These notes apply to firmware for EAMs, including embedded variants (such as the DM24SxEAM or any *TDE instrument). For DCM hardware, please see the DCM firmware upgrade page.

General instructions

If you need to do any pre-upgrade work on your system, such as changing the network configuration, check the current firmware version, as described in the previous paragraph.

• If it is above 10,000, the relevant manual is MAN-EAM-0003 ( PDF or HTML).

  You will find the upgrade instructions further down this page.

• If your Platinum system currently runs firmware before build 10,000, the relevant manual is MAN‑EAM‑0001 ( PDF or HTML).

  You will then need to follow the instructions on the EABI upgrade page to perform the upgrade itself, as described below.

Upgrade instructions

Important notices

• EAMs

  • Release 10942 or earlier

    After the upgrade, it will not be possible to use the web interface to reboot the EAM. Either use the command line (simply run the command reboot) or physically power cycle the EAM when the upgrade is complete.

  • Releases earlier than 10000

    See the EABI upgrade page for full instructions.

• NAM Mk2s

  No special action is required.

• NAMs

  • Release 10942 or earlier

    After the upgrade, it will not be possible to use the web interface to reboot the NAM. Either use the command line (simply run the command reboot) or physically power cycle the NAM when the upgrade is complete.

  • Releases earlier than 10000

    Before build 10000, use ssh (or serial port, if configured) to upgrade. After upgrading from a build earlier than 10000 to a more recent version, there will be several FATAL: kernel too old messages. Please run /sbin/manual-post-upgrade to resolve this.

2018-01-30 : release 15667

This release has three main components:

• Changes to how the CD 1.1 metadata flags are set when an Affinity loses GPS lock;
• A change in how the Affinity step-calibration signal behaves, introduced for DM24 compatibility; and
• A fix to gdi-link to stabilise connections when receiving data from a Minimus.

In detail:

• The DAS (now Affinity) ADC input driver, das-in, release 0.5.11
  • Changes to when the CD 1.1 metadata flags are set during GPS drop-outs.
  • Changes to the step calibration signal for DM24 compatibility. Note that this behaviour no longer follows the documentation, although the on-screen description is correct.
• platinum-builder/gpsd
  • Additions to identify the difference between no GPS information at all and no GPS fix information. This adds an online status to the shared memory interface used by das-in and gps-status to use to identify when lock is lost but NMEA sentences are still being received.
• GPS status reporting, gps-status, release 1.0.4
  • Changes to identify the difference between the absence of NMEA sentences and the case where sentences are present but missing any fix information.
• The sensor/digitiser command and control framework, Pt-web, release 0.2.25
  • Change the image for the instrument absolute step calibration to reflect the new behaviour.
• Code to link two (possibly remote) GDI multiplexers, with backfill, gdi-link, release 1.2.10
  • This fixes a problem that was causing dropped connections to Minimus digitisers when unknown GDI commands were received. Unknown GDI_COMMAND_MARKER messages now cause a LOG_NOTICE message to be printed, after which service continues.
• Code to send data using Block Recovery Protocol over a serial link, gcf-out-brp, release 1.0.13
  • No longer exits following a terminal mode request. The previous behaviour was causing data gaps because the last received block sequence number, which is used to monitor continuity, was held in memory and was being lost on service exit.
• The platinum firmware upgrade/mirror tool, Pt-firmware-tool, release 1.0.6
  • This release consolidates a feature which allows a NAM or other Platinum system with sufficient disk space to be used as a firmware mirror. This is useful when attempting to upgrade instruments with poor Internet connections and also when wishing to upgrade multiple systems on a network with no public Internet connection. Please contact for further information about this feature if you feel it could be of use to you.
• The client for Güralp Discovery, guralp-responder, release 0.0.2
  • This release reinstates the support for IP address aliasing which was reverted in the previous release.

2017-12-13 : release 15628

This release features the addition of a responding client for Güralp Discovery, allowing Platinum units to appear in the results when Discovery scans a network. Users can then access some Platinum data via the "Live view", "Show on map" and "Visit web-page" features of Discovery.

Other changes include:

• Platinum basic system files, Pt-baselayout, release 2.4.25
  • Add a default recycle value for gdi-record and a script to upgrade existing configurations.
  • Add default configuration files and an auto-start file for guralp-responder.
• The configuration interface, config-base, release 2.1.3
  • Correct a bug that mangled some error reports at the bottom of CGI pages.
• Configuration scripts and templates, config-scripts, release 2.3.11
  • Restores the configuration page for gdi2dbi. This is hidden by default: contact support if you would like to experiment with this feature.
  • Add a default recycle value for gdi-record.
  • Add the required configuration files for guralp-responder.
• A driver for storing sample data in a database, gdi2dbi, release 1.0.2
  • Update for libdbi-0.9.0 API change. Some functions have been deprecated.
• Common GCF block transmission functions, libgcf-out, release 1.0.17
  • Fix a bug in gcfout_chanlist_get() that caused channels to be displayed incorrectly in the serial port configuration for gcf-out-brp.
• The client for Güralp Discovery, guralp-responder, release 0.0.1
  • First release of the guralp-responder daemon in Platinum. This is the client side of the Güralp discovery protocol, which allows Platinum systems to identify themselves to the Güralp Discovery program.
    Please note this does not allow Discovery to change any values within the unit. It allows display of it's serial number and name, software version, unit type, uptime, IP address and netmask.
    
    This feature will not be enabled automatically after an upgrade: If wanted, the user must activate it explicitly.
• A tool for building the Platinum firmware, platinum-builder
  • Enable gdi2dbi on NAMs. Note this also rebuilds postgres and changes it from being a complete server implementation to a client only application. The update upgrades and rebuilds libdbi and libdbi-drivers. The change to client only is because there was not room on NAM-mk2 for the server code and there has only ever been a single customer for this.
  • Add guralp-responder to allow Platinum units to communicate with Güralp Discovery for the first time. This is a display-only process: changes to the configuration of the Platinum unit are not supported other than via the normal mechanisms (including, of course, the web interface).

• Bug-fixes:
  • Code to link two (possibly remote) GDI multiplexers, with backfill, gdi-link, release 1.2.9
    • Various changes to handle corrupt backfill files at the sender. Added more useful log messages for when things do go wrong. Also renamed corrupt backfill files to filename.corrupt when identified so they don't keep causing errors.
  • The SEEDlink server, seedlink-out, release 1.2.2
    • Fix a bug which meant the server did not display a BAD status if it had never received any data.
  • Platinum basic system files, Pt-baselayout, release 2.4.24
    • Add migration script for already existing gdi-link-tx backfill directory-cleaners. These will be renamed after the instance that they service. Also creates a directory-cleaner for any gdi-link-tx instance that has backfill enabled.
  • Configuration scripts and templates, config-scripts, release 2.3.10
    • Changes to the gdi-link-tx configuration mechanism so that, if backfill is enabled, a directory-cleaner instance is automatically created for it.

  • The library and tools for structured SoH representation, libxmlstatus, release 1.0.12
    • Downgrade a log message from Error to Warning.
  • A tool for building the Platinum firmware, platinum-builder
    • Efficiency improvement patch for libiso8601.

2017-08-01 : release 15455

This release provides a number of changes. In summary, it provides:

• changes to GDI metadata handling;
• the addition of Brown-noise calibration to Affinity (only);
• various bug-fixes;
• better control of clock drift on the Affinity; and
• a change to the SEED channel-name mapping to support the Minimus.

(Some package updates encompass changes from more than one of these categories.)

In detail, by category:

• Bug-fixes:
  • Common utility code, libgslutil, release 1.2.14
    • Addition of some safety checking to the reads_templatev() functions rather than blindly trying to access the data and potentially causing a crash.
  • Code to link two (possibly remote) GDI multiplexers, with backfill, gdi-link, release 1.2.8
    • Fix to prevent a crash in gdi-link-rx when receiving corrupt backfill information from a very old release of Platinum.

  • Configuration scripts and templates, config-scripts, release 2.3.9
    • Changes to improve the handling of GDI metadata within gdi2cd11 config. This includes changes to the help displayed and a change to the default value for the Max clock differential.
  • The SEED channel-name mapping library, libseedmap, release 1.0.6
    • Don't output duplicate names as this can be both confusing and cause problems if copied into the configuration.
  • The GDI meta-data handling subsystem, gdi-metadata, release 0.1.2
    • Changes to how metadata is handled improving and making it more efficient.
  • The DAS (now Affinity) ADC input driver, das-in, release 0.5.9
    • Addition of Brown-Noise calibration.
    • Changes for handling of GDI metadata.
    • Fixed a calibration monitor scaling problem that was causing problems when switching between regular operation and calibration.

    • Changes to GCF tap numbering.
• Calibration:
  • The sensor/digitiser command and control framework, sensor-control2, release 2.0.6
    • Addition of Brown-Noise calibration for Affinity only.
  • The sensor/digitiser command and control framework, Pt-web, release 0.2.21
    • Added sensor gain/offset to Data acquisition config page.

    • Addition of some help information on Data acquisition config page.
• Minimus support:
  • Stream-name mapping library, libgcfmap, release 1.0.2
    • Update mapping to support Minimus. This includes:
      • adding support for an alternate separator character
      • skipping leading zeroes (0s) in GDI names (as this cannot arise in a GDI to GCF conversion),
      • checking metadata for gcf-channel-name, then ChannelName,; and
      • supporting M-COMPONENT in metadata.
      Some of these changes have been fixed in the latest firmware build for Minimus but there may well be units running old software so it is better to handle this gracefully.

This release provides the following changes:

• The Linux message-handling subsystem, libmsgbus, release 3.0.1
  • Improve robustness when receiving a corrupted message. This should stop gdi-link-rx from occasionally restarting during backfill.
  • Fix a problem in the TCP buffering code that could occasionally cause corrupted messages. This should resolve a problem with stuttering or pausing gdi-link backfill that is sometimes observed.
  • Add a hybrid Unix blocking I/O model that is intended for some upcoming improvements to gdi-base handling of fast backfill. Does not affect anything yet.
• Platinum basic system files, Pt-baselayout, release 2.4.9
  • Fix a problem that could occur when configuring serial ports. From build 14052, it has been possible for the serial port service to start at an incorrect baud rate compared to the configuration. This is typically seen after use of the serial port diagnostics tool or after a full reset to factory defaults. This release permanently fixes the problem and no action is required from the user for any affected port; the proper settings will take place after the upgrade and reboot.

  The digital compass/orientation sensor subsystem, dcompass, release 1.0.5
  • Consolidate serial port settings into one file to avoid them getting out of sync with the configuration interface.
• Güralp data interconnect, gdi, release 1.4.0
  • Port to latest I/O libraries. This should not change behaviour (other than being very slightly more efficient) but provides features needed for some upcoming improvements for fast backfill.
  • Use system-wide policy file for multi-user socket control.
  • Do not directly display status from gdi-base. The input and output modules are the important ones. Under XML status the tab is now hidden by default and it is no longer displayed on LCD.
  • Time out stopped segments (caused by time tears in GCF) more quickly and efficiently.
• Support programs for DM24/CD24 (BRP mode), dm24-support, release 1.1.24
  • Switch to new I/O libraries.

  • Fix gdi-link-tx built-in backfill verification test for single-sample messages with state of health updates. In practice, this could have caused backfill on 1sps streams to have failed.

2014-08-18 : release 13665

A subtle tool-chain issue for the original NAM (not mk2) platform has been causing some ABI issues since release 13015. This has resulted in programs crashing with segmentation faults or illegal instructions. This has now been resolved in release 13665 which recompiled all packages for the NAM to flush out the issue. Testing for regression of this issue will now be carried out for each release.

2014-08-14 : release 13664

This release provides the following major changes:

• A new instrument control system (sensor-control2) has been implemented. It brings an improved control web page, and has features needed for the upcoming DAS (now Affinity) platform.
• gdi-link now disables terminal access by default, to prevent unauthorised DM24 configuration or firmware changes. Sensor controls can be enabled or disabled separately and are enabled by default, hopefully limiting the number of affected deployments.
• An Atom (RSS-compatible) feed is implemented for triggered events.

In Detail:

• The sensor/digitiser command and control framework, sensor-control2, release 2.0.0
  • A new subsystem for controlling instruments (sensor mass lock, unlock, centre and the digitiser's built-in calibration signal generator).
  • Works with existing Güralp equipment (DM24s and CD24s in low latency mode) as well as with the new DAS (now Affinity) digitiser.
  • Works through gdi-link so that e.g. a NAM can control instruments on any EAM or DAS (now Affinity) units from which it is receiving data, regardless of NAT. This mode also allows DM24 terminal access to be switched off while still allowing sensor control, in order to secure the system against accidental or malicious reconfiguration or firmware changes.
  • New web page.
  • Command line tool (sensor-control and also adc-command) remains 100% compatible so existing scripts will continue to work unchanged. There is, however, a new interactive, dialog-driven mode which is much easier to use.
  • On the DAS (now Affinity), supports configuring the polarity of the sensor control lines to "active-low", "active-high" or "automatically-detected".
• Code to link two (possibly remote) GDI multiplexers, with backfill, gdi-link, release 1.2.0
  • *IMPORTANT CHANGE TO DEFAULTS*: remote DM24 FORTH terminal access is now disabled by default. It can be re-enabled on the system that is running the transmitter, gdi-link-tx.
  • sensor-control2 subsystem integration.
  • New commands are available (if accepted during negotiation; so newer versions of gdi-link will continue to inter operate with older versions) for instrument control. Allows easy initiation of operations such as mass centring and calibration signal generation.
  • sensor control commands are logged on both the originating and the target system, with the peer names, so it should be clear from the log file who initiated an action and when.
  • remote sensor control can be turned on and off independently from remote DM24 FORTH terminal access. Remote sensor control defaults to enabled. This allows a system to be configured to protect against accidental or malicious reconfiguration or firmware changes of the ADC module while still allowing convenient remote control of sensors.
• The triggering, event recording and post-processing subsystem, gdi-trigger, release 0.2.2
  • Implement Atom feed of events.
• GPS status reporting, gps-status, release 1.0.2
  • Workaround for problem in gpsd shared memory transport.
• Common miniseed output code, libminiseed-out, release 1.2.0
  • Fixes for time-window retrieval mode. A cleaner, faster implementation of this function should resolve issues with client timeouts when requesting data by time window.
• The miniseed record generator for Platinum/GDI, gdi2miniseed, release 1.2.4
  • Updated to work with libminiseed-out release 1.2.0
• The SEEDlink server, seedlink-out, release 1.2.0
  • Fix some minor issues (such as status messages, or the results of a request that matches no records) relating to FIFO and time window requests.
  • Improve the implementation of time window retrieval to start returning records much more quickly than before, thus avoiding client timeouts.
• Support programs for DM24/CD24 (BRP mode), dm24-support, release 1.1.19
  • Integrate with new sensor-control2 subsystem.
• Code to acquire data using Block Recovery Protocol over a serial link, gcf-in-brp, release 1.3.2
  • Port to libgcf-in v1.3.0
• Code to acquire data using Scream network protocol, gcf-in-scream, release 1.0.7
  • Port to libgcf-in v1.3.0

  • Add gdi-trig-atom.cgi link (Atom feed generator for triggered events).
• The Platinum web interface, Pt-web, release 0.1.22
  • Fix confirmation being shown when saving timing configuration.
  • Add a new instrument control page:
  • Uses the new sensor-control2 subsystem.
  • Only a single link is shown in the left-hand menu, because the page lets you control all instruments, and because it prevents the menu holding stale data if the system is reconfigured.
  • Presentation of the controls has been greatly improved so that they are easier to use.
  • Improvements for trigger configuration:
  • Better dialog titles and buttons when configuring a trigger or a computed parameter
  • Highlight fields with invalid values that are preventing the configuration from being saved
  • Integration with gdi-trig-atom.cgi for Atom (RSS) feed of triggered events.
• Configuration scripts and templates, config-scripts, release 2.1.37
  • TCP to serial converter: fix saving of the IP address filter.
  • GCF over serial port receiver: fix disabling of BRP.
  • gdi-link: add some help, don't double-hide the advanced section, and add support to the transmitter for whether sensor control and/or DM24 FORTH terminal access are enabled (the options are independent).
• Simple network configuration scripts, console-config, release 1.2.0
  • Add some new, simpler command-line tools for manipulating configuration files. These will mainly be used by internal programs, but can also be useful for scripting automatic changes and for support queries.
• Code to record raw data from attached device on serial port, serial-recorder, release 1.1.0
  • Always close down and start a new file on an hour boundary; Don't rely on this process being triggered by more data arriving. This is better for systems configured to capture occasional output.
• A CGI program allowing control of various Platinum functions through XMLRPC, xmlrpc-control, release 1.0.3
  • Fix command for flushing to disk.
  • List all instruments we can control, including the new low-latency CD24 and DAS (now Affinity) instruments.
• Support code for Pt-web, libgslwt, release 1.0.7
  • Bug-fix for some internal library code that wasn't used anywhere visible.

  Code to display Quickstatus files on an attached LCD module, lcd-statuswatch, release 1.1.2
  • Move cleanup of quickstatus data on process exit into the library.
• GPS status reporting, gps-status, release 1.0.1
  • Initial release, for NAM and upcoming DAS (now Affinity) only.
  • This program will export GPS status information from gpsd to XML status.
• Platinum basic system files, Pt-baselayout, release 2.3.24
  • For NAM units with a GPS receiver, allow gpsd to accept TCP connections from remote hosts. This allows the use of e.g. the xgps program to get detailed realtime GPS information.
  • For NAM units with a GPS receiver, add a service to expose a new "GPS" status tab.
• Configuration and status monitoring for NTP, ntp-wrapper, release 3.0.2

2014-06-17 : release 13411

This release provides the following changes:

• Common functionality for CD1.1 modules, libdata-cd11, release 2.0.0
  • New frame splitting/building code to allow a common implementation of consistency tests across all modules.
  • Removed mux IPC code as it is no longer common between different modules.
  • Generally improve error checking and handling, and provide more common, consistent utility functions for parsing data.
• The CD1.1 sender, data-out-cd11, release 3.0.0
  • A new IPC mechanism has been implemented to allow for more robust data servoing. Now when there are multiple senders to different destinations they cannot interfere with each other or with receivers, and yet they are able to cope with vastly different link speeds and fault conditions.
• The CD1.1 multiplexer/frame database, data-mux-cd11, release 2.0.0
  • This release implements a new IPC mechanism which allows servoing of data rates independently for different modules. Receivers can now receive as fast as we can synchronise data to disk; senders now have notifications (fast) and data transfer (slow) decoupled. This allows all modules to be as independent as possible yet ensures data are never lost, even when inbound data rates are potentially much faster than outbound.
  • This release also implements "generation counters", which are simply a more explicit way of ensuring that a relay station does not transmit duplicate old data when one (or more) array element is back-filling.
• The pass-through CD1.1 receiver, data-in-cd11, release 2.0.0
  • Improve validation of inbound frames, to ensure we don't accept data on the TCP link that is later rejected by other parts of the system.
  • Implement a new IPC mechanism that allows the receiver to servo to the highest speed possible, ensuring that data are written to disk before it is acknowledged to the sender.
• The CD1.1 subframe generator for Platinum/GDI, gdi2cd11, release 1.4.0
  • Update to match new IPC scheme used by other modules. This is a much smaller change for this module, as the new semantics exactly match the way it was expected to work previously.
• The Quick Seismic Characteristic Data transmitter, qscd-out, release 1.3.1
  • Add XML status output to QSCD sender
• Support programs for DM24/CD24 (BRP mode), dm24-support, release 1.1.18
  • Update bundled firmware versions: CD24 to v.322 and DM24mk3 to 106b57s.

2014-06-14 : release 13360

This release provides the following changes:

• The Platinum web interface, Pt-web, release 0.1.19
  • Timing setup page: show the current timing mode at the top of the page, and skip rows when saving the NTP table and the peer has been left blank but the options are still filled out.
  • Trigger configuration page: changing the instrument labels now works again. Also fix the appearance of the save dialog.

2014-04-14 : release 13357

This release provides the following changes:

• The secure sockets layer library, OpenSSL, release 1.0.1g

• Platinum basic system files, Pt-baselayout, release 2.3.23
  • Fix for services displaying as "restarting" on long-running systems.
  • Fix for systems configured to 10BASE-T with no duplex setting: these are now considered to be half duplex.
  • Regenerate the SSL key used by the webserver, in case the old key material was leaked due to the openssl heartbleed vulnerability. A new key and self-signed certificate will be generated on each machine.

2014-03-06 : release 13349

This release provides the following user-visible change:

• Code to link two (possibly remote) GDI multiplexers, with backfill, gdi-link, release 1.1.6
  • gdi-link-tx now verifies its on-disk backfill records before transmission, avoiding a situation where a corrupt frame would cause the link to be dropped continually.

2014-03-03 : release 13345

This release provides the following user-visible changes:

• The pass-through CD1.1 receiver, data-in-cd11, release 1.3.1
  • Fix some problems encountered in the XML status code which could lead to crashing under some circumstances.

2013-11-19 : release 13015

This release contains a number of internal code changes such as resolving C
compiler warning messages, switching to a simpler and smaller event handling
library and using more tools from busybox to avoid bringing in large software
packages. The following packages have been affected by these changes:

• envirolog.cgi
• gcf-in-brp
• gcf-out-brp
• gcf-out-scream
• gdi
• gdi2gcf
• gdi2miniseed
• gdi-monitor
• libcgic
• libdata-gcf
• libframesettrack

• libgcf-in
• libgcf-out
• libxmlstatus
• power.cgi
• Pt-firmware-tool
• Pt-storage.cgi
• Pt-user-admin
• spyrus-utils
• xmlstatus.cgi

Another primary addition in this release is a new, consistent way of handling and reporting timing configuration across Platinum. Now a single web page allows configuration of the timing mode and makes it clear how the DM24 sample clock is synchronised separately from the Linux system clock.

There is some further preparatory work for the new DAS (now Affinity) platform which affects the following packages:

• gdi2gcf
• ioline
• libgcf-in
• libseedmap

• Pt-web

A detailed list of user-visible changes, excluding the smaller changes from above:

• The library and tools for structured SoH representation, libxmlstatus, release 1.0.9
  • Rate limit error messages to the system log.
• Support programs for DM24/CD24 (BRP mode), dm24-support, release 1.1.15
  • Fix two bugs in the configuration web page:
    • properly check and report whether unified status is enabled on a CD24
    • fix a memory corruption bug (which could have led to corrupt or crashing display, but would not have affected the actual DM24 itself)
  • Build system and install fixes.
  • Fix stale process detection in libdm24terminal. It should no longer mark a terminal as stale if the owning process executable is moved or a symlink.
  • Fix potential symbol clashes in libdm24terminal.
  • Fix build issue in libdm24terminal.
• Code to acquire data using Block Recovery Protocol over a serial link, gcf-in-brp, release 1.3.1

• The triggering, event recording and post-processing subsystem, gdi-trigger, release 0.2.0
  • Fixed a bug where the dimension was not recorded for periodograms.
  • Add programmable serial port output (sorry, no GUI configuration yet).
  • Add programmable email output (sorry, no GUI configuration yet).

2012-06-13 : release 11928

This release updates OpenSSH to version 6.0p1 and includes multiple changes.

• Platinum basic system files, Pt-baselayout, release 2.3.4

• Configuration scripts and templates, config-scripts, release 2.1.17
  • Minor improvements to file name entry.
  • Minor improvements to directory-cleaner page.
  • Add SAC file recorder configuration page.
• Configuration and status monitoring for NTP, ntp-wrapper, release 2.0.0
  • A rewritten NTP scanning subsystem which is much more sensitive to changes in NTP lock status. Now it will report that NTP is unlocked in some situations where is used to report a large difference instead.
  • Exposes some additional information about the clock source (NTP peer or GSL digitiser) via XML status.
  • Introduces a grace period of 30 minutes at system start where it will allow NTP time to lock on and synchronise the clock before highlighting an error state in XML status.
  • Also exposes the lock status in a machine-readable fashion for other programs on the system to use, so they are consistent with the status as reported by the scanner.
• Code to output NMEA and PPS based on NTP status, ntp-to-nmea, release 1.2.0
  • Use new NTP status flags from the new NTP scanning subsystem.

This release contains a number of technical changes with little or no user impact:

• GCF audit log library/tools, libgcflog, release 1.1.1
  • Various internal code tidy-ups.
• Library for manipulating unified status (SOH) information, libdata-unified-status, release 1.1.0
  • New status bit for mass centre operations (NB: not supported by DM24)
  • Bugfix where rapid GPS longitude changes would only propagate slowly

• Common utility code, libgslutil, release 1.2.0
  • Drop some unused functionality (forces ABI change).
  • Fix problem with serial ports sometimes being opened non-blocking when they should not have been; might have caused the odd strange error when e.g. upgrading CD24s. The majority of Platinum code uses non-blocking by default so the effects were very limited.
  • Add common code for writing logs to /var/crash.

2012-03-14 : release 11473

This release contains a number of minor improvements:

• The CD1.1 multiplexer/frame database, data-mux-cd11, release 1.3.3:
  • A system losing power at precisely the wrong point could end up with a frame that had duplicate sub-frames from another time-stamp. This has now been fixed.
• The Platinum basic system files, Pt-baselayout, release 2.3.2:
  • Provides a security fix for a symlink vulnerability in /tmp.
  • Some improvements to I²C/EEPROM handling on the EAM. This should make temperature sensors work reliably if they have been fitted, and provides an easy way to recover if the EAM fails to find ports/hardware after doing a factory reset (contact for instructions).
• The configuration scripts and templates, config-scripts, release 2.1.16:
  • This release removes some old configuration pages that aren’t used any more.
• The SoH library, libxmlstatus, release 1.0.7:
  • This release contains an internal code fix.
• The Platinum web interface, Pt-web, release 0.1.5:
  • Adds a new factory interface, which may also be used on support calls.
  • Saving trigger configuration no longer disables other services by mistake.
• The configuration interface, config-base, release 2.0.11:
  • Solves a problem that could prevent deletion of table rows in the web configuration interface.

2012-03-16 : release 11439

This release contains three minor changes:

• The triggering sub-system, gdi-trigger, release 0.1.10:
  • Fine-tuning of a timer used to detect errors.
  • Now takes GCF variable gain into account.
• Web page support, Pt-web:
  • Increased page load timeout.

2012-03-16 : release 11423

This release contains a number of minor bug-fixes and improvements:

• The main status display, system-status, release 1.1.1:
  • No longer displays a reading (voltage, current, temperature) as “0″ if it’s actually missing.
• The digital input/output library, ioline, release 1.0.11:
  • Fixes a problem with the error handling in CGI script.
• The triggering sub-system, gdi-trigger, release 0.1.9:
  • No longer records calibration channels.
  • No longer records partial events if some channels are missing. The event cannot be recorded in this case.
• The manual timing system, force-digitiser-timing, release 1.0.0:
  • Reworked script. No longer attempts to use NMEA to carefully control the time, as we could not always meet the tolerances required by the DM24 and this would cause data gaps and strange status reports. Instead, forcefully sets the RTC on any attached digitisers and reboots them. This is less elegant in principle but works well in practice.GSL always recommend that GPS is used as a timing source.
• Web page support, Pt-baselayout, release 2.3.1:
  • Fixes a bug where selecting the “System status” web menu entry to refresh that page while logged out would ask for user-name and password.
  • Switches to runtime detection of temperature sensor. This should improve the availability of this reading. Note that not all EAMs have temperature sensor chips fitted.
  • Fixes a bug in the NTP startup which was introduced alongside manual timing mode.
• The I²C support library, ioline-gsli2c, release 1.2.0:
  • Remove ioline-provider-lm92. The generic -hwmon provider can be used instead.
• The status monitoring and reporting system, libxmlstatus-parser, release 1.0.2:
  • Developer-only changes.

2012-03-16 : release 11390

This release contains a number of minor bug-fixes and improvements:

• The triggering subsystem, gdi-trigger, release 0.1.8:
  • The subsystem now uses first 100 samples of time series data to prime IJMA IIR filter, giving results more consistent with the original frequency-domain implementation.
  • The result file now includes raw IJMA value alongside the scale.
• The web infrastructure, PT-web, release 0.1.4:
  • Improved handling of warnings when triggered events are being displayed during windows where new events are being recorded or old events are being expired.
• The gcf receiver, gcf-in-brp, release 1.2.11:
  • Corrects operation when in manual timing mode. We no longer try to set the system clock in this case.
• Platinum infrastructure support, Pt-baselayout, release 2.3.0:
  • Switches to using the new ‘/run’ directory idiomatic to Linux (http://lwn.net/Articles/436012/)
  • Adds hardware monitoring support for the NAM-mk2.
  • Adds PicoLCD 256×64 support for NAM-mk2.
  • Incorporates a tweak to update the XML status display of the version number immediately after an upgrade (but upgrades should always be followed by a reboot!).
  • Fixes a potential problem with gdi-link-rx missing a required configuration value after re-flashing a system.
• The status subsystem, xmlstatus-assert, release 1.0.3:
  • Fixes a problem where the configuration file could become corrupted.
• Hardware support for the NAM-mk2 platform, nam-mk2-init, release 1.0.1:
  • Removes some redundant filesystem mounting code.
• IIR filtering support, libiir, release 1.0.2:
  • High-order Butterworth filters now use 2nd order components rather than 4th order. This should avoid numerical instability.

2012-03-01 : release 11353

This release contains minor changes to the iolinefacility and multiple changes to the new triggering subsystem:

• A hardware support infrastructure, ioline, release 1.0.10:
  • Fixes a potential problem for non-root users.
  • Now supports the generic Linux hwmon layer.
• The triggering system, gdi-trigger, release 0.1.6:
  • Level Trigger:
    • Another fix to ensure that operation without a configured filter works.
    • Fixes for floating-point source data.
    • Avoids possible corruption of the filter when triggered.
    • Level trigger messages are now inhibited for 1s of samples after any sample exceeds the threshold; this reduces CPU usage while ensuring long events (spanning multiple records) are properly supported and logged.
    • Improved log messages to contain the value and exact time-stamp of the sample that exceeded the level threshold.
  • STA/LTA Trigger:
    • Improved log messages to contain the STA value, LTA value and exact time-stamp when the ratio was exceeded at the point of triggering.
  • Trigger Matrix:
    • Remove all use of the Linux system clock from the equation. As long as data are flowing continuously and at a normal rate from the ADC module, the matrix will now function normally.
    • Re-factored and simplified the timers used to coalesce trigger messages from multiple sources. There is only one timer now, and it does not need to fire at an exact interval. This should be more robust now.
    • Re-factored and simplified the timer used to start the recorder, by adding in a new “pulsed” action mode. It now sends a message to the recorder every time any vote is added or expired, and when the internal coalesce timer fires.
    • Improve logging of exactly what condition caused an event to be recorded (e.g. the sample values and time-stamps from each level trigger that exceeded the threshold). The logging combines individual messages from multiple triggers when voting is in operation.
    • Further fixes to the GPIO support.
  • Trigger Recorder:
    • Add a queue for event processing. If a lot of very short events are recorded in a short span of time, then this enqueues the post processing to avoid overloading the CPU. The queue is not limited and does not use significant memory so there is no limit to how many things are queued (only to how much raw event data can be stored on flash).
• The new web interface, Pt-web, release 0.1.3:
  • Trigger configuration for FFT: add option for DC offset removal.
  • Trigger configuration: fix saving of recorder action voting weight threshold.
  • Triggered event viewer: properly sort the event viewer summary table. Newest events are at the top.
  • Triggered event viewer: ensure that pressing the “View event” button always displays the correct event.
  • Triggered event viewer: ensure that the event detail tab displays the correct timestamp.

2012-02-20 : release 11333

This release contains two user-visible changes:

• The data recording subsystem, gdi-record2, release 1.0.2:
  • Now allows creation of deep directory trees when using rsync to record non-seismic data files.
• The triggering system, gdi-trigger, release 0.1.5:
  • This release fixes operation when a trigger is constantly being fired. Previously, channels could get out of sync in this situation.

2012-02-10 : release 11317

This release mainly affects support for connected digitisers, the triggering user-interface and the reliability of CD1.1 authentication.

2012-01-07 : release 10942

This release updates the leap second table to include the recently announced June 30^th, 2012 leap second. Leap seconds cannot be computed in advance so it is necessary to signal the declaration of new leap seconds to running applications. Platinum includes a leap second table which lists all known leap seconds; this table has to be updated when a new leap second is declared.There are two ways that a customer can get the updated table. Platinum systems with a permanent internet connection will check every week for updates to the table and will automatically download any that they find. The check occurs at 02:17 UTC each Saturday morning and the HTTP protocol is used to download the updates. Platinum systems without a permanent internet connection will acquire the updated table when their firmware is updated; this is the first firmware release where the leap second table includes the 2012 leap second.It is possible to tell whether the table has been successfully updated by running the command:

ls -l /usr/share/libiso8601/leap-seconds

The output will look like this:

-rw-r--r-- 1 root root 108 Feb 26 2011 /usr/share/libiso8601/leap-seconds

The size of the file is given in the 5^th field of the output. If the size is 108 bytes (as in the example), it is the old (pre-2012-06-30) version. If it is 112 bytes, it is the new version.

2011-12-11 : release 10931

This release adds support for the new, rack-mounted EAM-R and the rack-mounted CD24R8. Changes have been made to:

• Pt-baselayout:
  • Support added for the EAM-R
  • Minor bug fixes: disk flush buttons and storage daemon permissions
• xmlstatus-assert:
  • Fixed parsing of “enabled” value in configuration file
• The I²C support library, ioline-gsli2c:
  • Added a drive for the PCA9593 I/O expander
• The GCF BRP receiver, gcf-in-brp:
  • This now correctly identifies disconnected devices.
• A new tool-kit for supporting the use of USB-to-serial converters, usbserial-support:
  • A script, add-USB-serial.sh, allows a permanent USB-to-serial cable installation.
  • A new program, tty_map_tool, aids mapping of physical ports to USB serial numbers for multi-port NAMs.
  • A new program, run-cd24r8, automatically detects and runs CD24R8 digitisers with a USB-to-serial converter.

2011-12-01 : release 10896

This release contains a single bug-fix for the BRP receiver, gcf-in-brp:

2011-11-16 : release 10879

This release fixes a potential crash in gdi-link-rx when new clients are in the process of connecting. This seems to only have occurred on the NAM-mk2.

2011-11-16 : release 10874

This release contains a fix for a race condition, observed on the NAM-mk2, where sometimes, at boot-up, a service would only listen on either IPv4 or IPv6 addresses, but not both. This occurred because the service was started before any address was configured on the physical network interface, and the support library’s behaviour was to check for configured addresses before activating results for an address family. This check has now been removed.

2011-07-29 : release 10473

• Bug-fix: gdi-record was over-zealous about error handling. Some obviously non-recoverable errors triggered an infinite loop of re-tries. Such errors are now handled gracefully.

2011-07-28 : release 10469

This release contains a large number of improvements, as detailed below:

• GCF serial receiver: gcf-in-brp
  • Feature: an instrument that stops transmitting data is now highlighted in the status display.
  • Feature: terminal events are now logged to /var/log/messages.
  • Bug-fix: Stream IDs which, when encoded, contained a certain character could cause an unwanted terminal session to be started. This is now detected and avoided.
• Internal message handling: libmsgbus
  • Enhancement: improved output buffer for queued messages
  • Bug-fix: when writing data faster than they could be consumed,there was potential for corruption; This is now fixed.

  • Enhancement: Improved diagnostic logging for situations that cause a module restart.
  • Bug-fix: Simplified and corrected generation of outbound ACK/NACK frames (which indicate to a receiver which frames we still have available).
  • Enhancement: Further improvements to ACK/NACK handling: Processing of incoming frames is no longer deferred, even if backfill is in progress, and an extra field to keep track of which frames have been sent in the current TCP session was added to avoid duplicates.
• CD1.1 library functions: libdata-cd11
  • Feature: subframe presence tracking. This is useful for seeing how sub-frames propagate through the software modules, and is more generally applicable as a way to look for data gaps.
  • Enhancement: a feedback path between the multiplexer and source clients may optionally be employed. This helps data-in-cd11 to extend the feedback path back over the TCP link to the sender.

• Bug-fix: Commands such as minicom PortA now don’t print an error message on start-up
• Bug-fix: directory-cleaner configuration page errors now let you resolve them rather than just displaying an error message.
• One or two terminology changes concerning sensors/instruments

2011-05-27 : release 10254

• Minor cosmetic changes only.

2011-05-26 : release 10250

This release provides a new sensor control framework, designed to ease the implementation of many current and future sensor control facilities. The main user-visible changes are listed below:

• New menu category: “Control → Sensors”.
• Menu “Configuration → System” changed to “Configuration → Sensors”.
• A new, prototype sensor control screen.
• A new (but currently non-functional) menu item: “Tools → Sensors → FORTH terminal access”.

2011-05-25 : release 10246

• Bug-fix: The cd24-lowlatency-in service now ensures that mass position commands and offset-null commands work by forcing the CD24 sensor-type to 3.

2011-05-24 : release 10183

• Bug-fix: The XHTML MIME-type list now supports the preview of the digital compass subsystem.
• Bug-fix: Configuring specific media-types for the Ethernet interface now works correctly. If you have been affected by this bug, you should perform the upgrade, then run the command
  

  rm /etc/init.local/net_eth0

  and then reboot the system.

2011-05-23 : release 10179

• Feature: The gcf-out-brp service now uses the XML Status infrastructure.
• Feature: A new option now allows you to record system log files to disk.
• Feature: A new tool, cd24fw, allows upgrading of firmware on attached CD24 digitisers.
• Feature: This release contains a preview of a new digital compass / orientation sensor subsystem. There is no configuration or recording of time-series data yet.Note: this feature is not supported on legacy DCM platforms.
• Bug-fix: The dircopy feature no longer creates empty directories on removable storage devices.
• Bug-fix: The --restore-defaults option to the upgrade tool now works correctly on EAMs.
• Bug-fix: The syslog subsystem can now be restarted properly.
• Bug-fix: EAM serial ports now stay powered up when a program is accessing them. This might lead to increased power consumption if ports are configured but not in use, but decreased power consumption if ports have been configured to None and were previously powered up. This resolves issues where DM24s had undetected framing errors during terminal access and where CD24s went to sleep if a terminal was left open.

2011-05-11 : release 10117

• A new feature can raise an external hardware alert if monitored status parameters drop below configurable thresholds.
• Fixes a bug which would trigger undesirable behaviour in some subsystems if an EAM booted with an invalid date (pre-1970) in the real-time clock. The date is now forced to 1/1/1970 under these circumstances.

2011-05-11 : release 10083

• Fixes a bug in the “linux system” status display which incorrectly reported the statistics (size, free-space etc) of root partitions larger than 2GiB.

2011-04-26 : release 10071

• Fixes a display issue under IE where IE would not correctly split up configuration pages into their sections.
• Adds u3-tool (EAM, NAM and NAM64 only) for repairing Sandisk Cruzers which have the U3 firmware “feature” where Win32 has inadvertently activated it and destroyed the data.

2011-04-26 : release 10064

• Fixes some issues with the SeedLINK XML info packet creator. Tested with IRIS slinktool and slinktool from seiscomp-2.6 and seiscomp-3.0.

2011-04-20 : release 10060

• Fixes a bug which marked a newly-changed password as expired when the date is 1^st Jan, 1970 (which will be the case for a freshly booted DCM with no GPS fix).

2011-04-18 : release 10056

This release contains fixes for bugs in subsystems that have not yet been formally released:

• cd24-lowlatency-in: fixed a “midnight rollover” bug, which was due to the integral discontinuity of GCF date/time at midnight;
• cd24-lowlatency-in: fixed a bug where the service wouldn’t start unless a TCP copy service name had been configured (this is now optional);
• libiir: version bump; upstream version has improved initial conditions for IIR filters based on analysis of filter (fixes numerical instability in computation of IJMA for gdi-eventproc-ijma)

2011-04-08 : release 10048

• New feature: XML status assert daemon. A GPIO line can now be asserted when a system SoH parameter value falls below a configured threshold.
• New feature: Support for low-latency mode of CD24 digitisers. The CD24 digitiser has been provided with a new, low-latency mode which required an special, low-latency protocol in order to transmit data without the delays associated with the packetisation of GCF. The EAM can now receive data from the CD24 using this protocol.
• Fixed a bug where the configuration page for the GSTM server could occasionally be only partially displayed in the web interface.

2011-03-31 : release 10008

• Fixed a bug where formatting a disk would lead to only 2.0Gbyte being available. Simply upgrade and reformat any affected disk, or format the disk on another machine. Also applies to USB sticks (internal or external).
• GCF TTL and DM type fields are now a hidden field in XML status.

2011-03-22 : release 10000

• Compiler update for EAM. GSL have upgraded the C compiler and system libraries used on the EAM. This results in almost every file needing to be replaced. Because this process is sensitive to being interrupted partway through, we recommend it is not carried out on deployed units, and instead is only carried out when units are brought in for servicing or when a backup unit can be deployed immediately. Details of the upgrade procedure can be found here.
• New feature: multi-user support. The next version of Platinum brings a major change: support for multiple users. Each user has a distinct password and level of access. A user with only basic access may only be able to view the status of various parts of the system, whereas an advanced user may be given rights to control or configure certain components. New user IDs can be created and modified through the configuration system where their access levels can also be set. For users familiar with Linux, this is implemented using true Unix users and groups, so it also brings system-wide security. Please note this feature required fundamental changes to various parts of the Platinum operating system and there may still be situations where a user cannot accomplish something they should have been able to: please contact in such cases for a speedy resolution.
• New feature: XML status subsystem. An advanced state-of-health reporting system has been added to this release of Platinum. A newly-designed front page now shows the status of the GPS, hard disk, sensors and virtually every software component on the system in a simple grid arrangement, which will instantly highlight any problems on the unit. Viewing this status does not require authentication, which removes a step from the process of checking system operation. This information can also be retrieved as an XML file (perhaps using the XMLRPC interface) for machine processing. ISTI have developed a forthcoming iPhone/iPad app for viewing this status, and Seisnetwatch integration is planned.
• Units with optional extra flash modules now have information about the flash module on the front page. All units programmed since April 2011 will now have a marker in their EEPROM if a flash module was present on the original sales order, which will allow instant identification of units where the flash is malfunctioning or not fitted.
• Some XMLRPC controls have been added for automation. At present XML status can be retrieved and sensor control (mass lock, unlock etc.) is supported, as well as initiating a flush to disk. Much more will be added in future. Contact Guralp support for more information.
• When using an EAM to transmit GCF data through a serial port, it is now possible to use Scream to configure any DM24 instrument connected to the EAM. This has always been possible when using the network protocol, but has not been possible until now when using the serial protocol (BRP).This feature does have the limitation that data are not buffered while the instrument terminal is open.Please note that when using an EAM, Guralp Systems recommends the use of IP networking over serial data transmission if at all possible. This can be achieved over a serial line connection using PPP; please contact support for details. The web interface also allows control and configuration of attached DM24 and CD24 digitisers.
• A new, more robust mechanism of controlling sensors (lock, unlock, centre and calibrate) has been added. This has been extensively tested with the DM24mk2.
• A new sensor control page has been added which attempts to determine from the DM24/CD24 which options it should display. There is an auto-detect feature and a manual override.
• Results of long sensor commands (e.g. DEPLOY) now automatically scroll.
• The last few terminal sessions to DM24 are logged for debugging failures; use the dump-serial-log program on files in /var/log/libterminal to view the logs (or send those files to ).
• Improvements to the web interface presentation and usability have been made in several areas (especially the configuration pages).
• A traditional cron daemon (vixie-cron) has been added.
• Outbound email configuration now works correctly. Remember to run newaliases if you update the alias file by hand.
• The gcf-out-scream Scream server now tries very hard to keep the same COMxx number for Scream4.4/Windows compatibility. COMxx numbers should no longer change whenever the Scream server is restarted.
• Compression of SOH information from DM24mk3s was improved, should lead to less noise (and less bandwidth) in the gdi-link/gsms-out protocols.
• data-mux-cd11: a bug where deferred data (e.g. from a faulty DM24mk3) was not transmitted on to the sender under certain circumstances was resolved
• Fixed a bug where the friendly service name of gdi-base was not used while configuring gdi2gcf with a channel map.
• Fixed a bug in the WIN sender configuration script’s UDP mode (it was not allowing the form to be submitted).
• Temperature sensors should be more reliable. However a large number of units were shipped without the temperature sensor chip.
• Fixed a bug where over-voltage settings in ioline were not saved.
• Resolved a longstanding bug where NTP status would stop being updated after some weeks, with Malformed or unexpected reply messages in the system log.
• serial-recorder now copes with recording from a GPS unit (control lines were previously confusing it).
• Upgrade now always correctly reports old and new release numbers.
• The upgrade option on the web page no longer reports success on failure.
• New Unix apps: base64, iostat, last, pmap, traceroute6, who, xz.
• Platinum code now copes with previously-unknown non-time-series blocks from the DM24mk3, such as TS (trigger summary), which are passed through verbatim.
• Fixed a bug where the digitiser configuration page would say “Load complete” even if loading failed.
• Bugfix in the configuration pages when deleting a table row with a check-box.
• VLAN configuration is improved and previously-configured VLANs can now be deleted through the web interface.
• Significant improvements to starting, stopping and restarting services have been made.
• GSMS sender will now cope with dynamic notification of leap seconds..
• Configuration of 230400 baud on DM24mk3 units that support it is now available through the web interface
• Improved behaviour of the system when a service failed to start correctly. This should improve the behaviour of the service control commands as well as reducing the scope for getting the system into a state where it does not boot.
• Improved the wording of the NTP configuration page.

2010-11-08 : release 3796

• Fixed an “off-by-one” in data-in-cd11, so now this code is consistent with the code in data-out-cd11, the AFTAC receiver and the standard (but not the CTBTO software);
• The CD1.1 subsystems now use extra information in the heartbeat frames from the sender to mark any unavailable frames as unavailable in the receiver, to stop the receiver gap list from building indefinitely (e.g. in the face of a bug like the above).
• Some TCP changes have been made which may help with an intermittent problem where the BRP sender could lock up.

2010-09-06 : release 3772

• This release corrects a second problem with the CD1.1 sender channel filtering.

2010-08-25 : release 3768

• This release fixes a bug in the data-out-cd11 configuration which affected the channel filtering.

2010-08-23 : release 3764

• This release fixes a problem with the data-terminal command’s menu-driven mode, which was broken in the last release; It would always say “No terminal selected”.
• New versions of the terminal command functions have been introduced in order to support the DEPLOY command on the latest OBS systems. Command usage and results should not change.

2010-08-20 : release 3756

• This release adds support for conventional /etc/rc.local and /etc/rc.local.d processing.

2010-08-20 : release 3751

• This release contains a single change to the OBS section of the instrument control page. The time-out associated with the DEPLOY command has been increased to 25 minutes.

2010-08-13 : release 3748

• This release contains a single change to the CD1.1 sender which fixes interoperability issues for a specific customer.

2010-08-09 : release 3744

• Added an option to allow a GCF input process to set the system clock whenever it sees a 00 status block from an attached DM24. This option is enabled by Configuration → Serial → Port? → GCF input → Advanced → GCF timing. It is off by default, as it is only intended for coarse timing with a Mark 2 DM24. DM24mk3 and CD24 digitisers produce more accurate timing information, embedded in the RTStatus packets.

2010-07-21 : release 3719

• The time-out value of the OBS DEPLOY command has been increased because a new DM24 firmware build requires the terminal to be kept open for longer.

2010-07-19 : release 3699

• Further improvements to the support for LCDs on EAMs.

2010-07-16 : release 3696

• Adds preliminary support for external Liquid Crystal Displays (EAMs only).
• Adds DM24 state-of-health information to LCD displays, including those on 5TDs. If Unified Status blocks are enabled, real-time GPS, clock and data-quality flag information is displayed; if not, the DM24 status blocks are displayed verbatim.
• The RTD sender, implemented for a specific customer, has been removed from the distributed firmware as that customer no longer has a requirement for it.
• Additional improvements have been made to the upgrade script to correctly handle symlink problems when upgrading DCMs. Note: DCM users should install this upgrade twice, once to install the new upgrade script and once to execute it.

2010-07-15 : release 3670

• A new upgrade script handles a problem involving undeletable symlinks when upgrading DCMs. Note: This upgrade should be installed twice: once to install the new upgrade script and once to execute it, although this is only necessary on DCMs.
• Fixes a problem that could cause incorrectly displayed dates in the back-fill database of the CD1.1 sender.
• Various other CD1.1 resilience improvements.

2010-07-12 : release 3641

• Fixes a problem affecting interoperation with one particular CD1.1 receiver.

2010-06-25 : release 3628

• Fixes a problem that could stop CD1.1 calibration values from being applied.

2010-06-23 : release 3624

• GCF handling improvements:
  • All GCF packets with zero sample-rates (other than *01 and *SM) are now treated as text and passed through accordingly. Previously, unrecognised zero sample-rate packets were rejected. This supports the newly added *TS streams and provides future-proofing for any other new text streams.
  • The digitiser type, FIR filter tap-table look-up and variable gain settings are now passed as meta-data to GDI. The GCF compressor, gdi2gcf has been modified to read these data from GDI and reconstitute them in out-going GCF packets.
  • GCF now correctly handles the situation where a segment end requires three GCF blocks to be generated (one at 8-bit, one at 16-bit, and one at 32-bit compression).
• CD1.1 sender changes: A non-standard receiver was encountered that required more laxity in validity checking and a longer connection time-out. Configurable options to handle this situation have been provided: these can be enabled and adjusted from the “expert mode” screen of the CD1.1 sender configuration dialogue.

2010-06-22 : release 3559

• The CD1.1 transmitter, data-out-cd11, now has a configurable transmit queue size. This used to be fixed at 128k but the new default is 512k. This has improved performance when back-filling an array over a VSAT link.
• The time-and-date library, libiso8601, now correctly handles invalid times in the system clock, preventing some display and logfile corruption on DCMs between booting and first synchronising.

2010-06-07 : release 3551

• Added a script to set ad-hoc mode on a wireless network adapter and configure the associated link layer. Designed for use with specific customer software only and not intended for operational use. For more details, please contact .

2010-05-27 : release 3547

• This release contains the latest DM24Mk3 firmware image (in the /usr/share/firmware/DM24mk3 directory). There are no changes to the Platinum firmware itself.

2010-05-26 : release 3543

• The seedlink server (seedlink-out) is now tolerant of arbitrary white-space in received command strings. This allows interoperability with Anthony Lomax’s SeisGram2K software.
• The configuration screen for the RTD server (rtd-out) produced an inappropriate error message when no sender had previously been configured. This has been fixed.

2010-05-21 : release 3535

• Added support for the USGS RTD protocol over IP or serial links.
• Added a serial port recorder: Any serial port can now be configured to record to a file all data received over the port. Individual lines in the file are time-stamped.
• Improved accuracy of voltage monitoring.
• All digitiser configuration changes now cause a re-boot of the digitiser module so that the changes take effect immediately.
• The DHCP client now behaves better when operating in a relayed network.
• Fixed a bug in the Spyrus support whereby generating a new key-pair in an unused slot changed the active slot.
• Fixed a few bugs in the digitiser configuration page related to tap settings, triggering settings and short IDs. Added checks for invalid configurations which could cause the digitiser module to continuously reboot.

2010-05-11 : release 3488

• Improves debug logging and fixes a bug in the CD1.1 sender which affected systems with multiple senders: one sender reconnecting could halt the other.

2010-05-10 : release 3480

• Fixes a bug in the CD1.1 sender whereby if the first reconnect attempt after a valid connection ended failed, the reconnect timer was not rearmed. This is now resolved.

2010-04-30 : release 3476

• The pppd-watchdog service’s process termination and reboot triggering are now switchable separately (for applications using this service to monitor things other than pppd).

2010-04-29 : release 3455

• Added cURL and libcurl. The cURL program performs file-transfers using a wide variety of protocols, including HTTP, FTP, SFTP, TFTP and more. The libcurl library provides the same facilities for platinum modules.
• Some CD1.1 updates announced for release 3420 were not actually included in that release: this release remedies that.

2010-04-27 : release 3420

• CD1.1 “aux status” information is now 8-bit rather than 10-bit, and can now be displayed in the multiplexer subframe viewer.
• CD1.1 sender no longer resolves IPv6 addresses (the protocol is strictly IPv4 at present).
• The CD1.1 multiplexer subframe viewer now highlights fields that have caused attention bits to be set (e.g. GPS, timing).
• Improved Spyrus behaviour when re-initialising the card while it is in use (and various Spyrus tidy-ups).
• We no longer associate to unsecured wireless access points when we already have an access point configured, just not available
• Authentication key ID in outgoing CD1.1 data frames now changes as expected when cd11-management-tool is used to change it at runtime.

2010-04-1 : release 3360

• Changed behaviour of wireless networking: The system will not now automatically bind to an insecure network when no recognised networks are available.

2010-03-31 : release 3314

• Improved DHCP client: dhcpcd-5.2.1 brings many robustness improvements. This fixes the longstanding issue where booting a DCM/EAM without the network cable plugged in would lead to never getting a DHCP assigned address. It also adds resolv.conf and default route metric support for better behaviour on units with wired and wireless networks active simultaneously.
• Change gdi-link-tx to using hourly files for backfill: A minor tweak, this allows the size of the backfill directories used by gdi-link-tx to be controlled in a more fine-grained manner, allowing the use of gdi-link-tx backfill on units with smaller amounts of flash (e.g. DCMs).
• Robustness and configuration improvements for GSTM server: GSTM server now uses a flat configuration file rather than XML, making it much easier to manipulate by script (or by hand). Along with this, additional logging, debugging and watchdog features have been added.

2010-03-24 : release 3271

• rdisk and gdi-record now support flushing to disk from an external button (e.g. on 3EX with integrated EAM)
• Improved status reporting from rdisk (it now reports flush failures and also reports status information to an attached LCD).
• Basic SoH information is now transmitted in MiniSEED headers.
• Improved implementation of INFO command in the SEEDlink server.
• Bug fix: calibration commands with frequencies expressed in seconds now work reliably. An error which occurred when a calibration command was issued while a calibration was already in progress has been fixed.
• Fixed a problem which could cause display corruption when viewing GCF logs.

2010-02-15 : release 3170

• 3170 is the first release with EAM LCD support, in anticipation of LCDs being fitted to EAMs. The NAM/NAM64 LCD support has been rewritten to use the same framework developed for EAMs.
• Python 2.5.1 has been removed from the NAM/NAM64 build as it is no longer required by current modules. Python 3 could be provided if requested.

2010-02-08 : release 3143

• Recording to disk: the configuration page now allows the user to choose a destination when there are multiple options (e.g. “record to internal USB disk in tray” or “record to external USB device”).
• Improvements to seedlink XML info output.

2010-01-10 : release 3063

• Fix for setting up gcf-out-brp (GCF out) on a serial port for the first time under recent Platinum (would complain about missing “gcfout_dbdir” or “brp_dbdir” configuration entries in the log).
• Initial modem dial-in support (mgetty).
• Improved DM24 terminal support.
• Support for newer DM24mk3 bootloader and firmware, including (InfoBlock retrieval).
• Improved envirolog graph plotting CGI.
• Fix for pushing to network broadcast address in Scream server.
• Improved extract_miniseed and seedlink. New features added. Many of the seedlink INFO commands should work now, as should time window extraction.

2010-01-05 : release 3020

• Fix crash caused by custom DM24 compression settings

2009-12-11 : release 3016

• This fixes a bug in the gdi2cd11 configuration file handling which caused the location part of a manually mapped channel name to be ignored.

2009-12-09 : release 3012

• Addition of a command-line tool adc-command that can be used to send calibration/mass control commands to attached ADC modules.

2009-12-07 : release 3008

• Improvement to the CD1.1 converter (gdi2cd11) configuration template: Configuration of the channel description fields is now fully supported.

2009-12-04 : release 2882

• Fixed a bug whereby one of our packages (libev) interfered with another (libevent), causing gdi-base to lock up.

2009-12-02 : release 2819

• Hierarchical navigation bars have been added at the top of each CGI page.
• Some Javascript to scroll to previous location when changing sample rates on DM24 configuration page
• Added summary of Baud rates on serial port configuration page
• Added “favicon” added to web interface.
• Improved robustness of NMEA input code.
• Improved interface when deleting items from network interface configuration (IP aliases, static routes, wireless network definitions, directory cleaner entries)
• nmea-out replaced by ntp-to-nmea. This is pretty transparent as configuration is unchanged. New option: threshold for max acceptable µs drift from NTP.
• libsysevents removed in favour of syslog. “System events” link gone from front page.
• Spyrus configuration menu entry only displayed if spyrus present.
• Improved user interface on environmental log plotter.
