Firmware for the Güralp DM24 Mk3

Güralp DM24 digitisers manufactured after 2005 are of the Mk3 type. Firmware for these modules has a version number above v.100.

If you are visiting this page to download firmware to address the GPS WNRO problem, please click here to visit the special WRNO firmware download page instead, where you will find a simpler, more targeted procedure.

The digitiser has three firmware components, which can be updated separately: the main system program, the DSP code and the boot loader. The .zip files on this page each contain all three of these files. If the bootloader in use is not the latest version for the required firmware (i.e. bootloader 3.02 for v.107 firmware and bootloader 130 for v.103 firmware), it should be upgraded first.

To find out what firmware version you are currently using, right-click on the digitiser's icon (not the Local or the Comxx icons) in Scream!’s main window and select Configure from the pop-up menu. This will open the Configuration setup window. The version number is given in the Software revision box.

V.106 firmware has been deprecated because it does not support the latest Güralp GPS receivers. It will no longer be maintained. All users running v.106 are advised to upgrade to the latest v.107 build. This requires the latest v.3 boot-loader and, if you change the boot-loader, you need to reload the system code and DSP code. This means that a complete upgrade of all firmware components, starting with the boot-loader, is required.
If you are upgrading from either

it is necessary to run a command in order to reset certain system timing parameters. Failure to do this can compromise the accuracy of data time-stamps. After the upgrade is complete, allow the system to boot normally and then copy and paste the command below to the command-line of the digitiser, and then reboot the unit. This command sets a number of values in the non-volatile configuration memory and only needs to be executed once per system.

Firmware for units without USB support

This firmware should also be used for all instruments and data acquisition systems with embedded DM24 digitisers.

Download the latest v.107 DM24 Mk3 firmware, a 276K .zip file including:
  • system program v.107 build 29

Earlier versions

Earlier versions of the DM24 Mk3 firmware, for testing or reference, may be downloaded from: the DM24 Mk3 download directory.

Upgrade instructions

There are two ways to upgrade a DM24: automatic and manual. You should use the automatic method if you are upgrading any of the following:

If you are upgrading one of the systems listed above, follow the instructions under "Automatic Upgrades", below.

Only if you do not have access to an EAM and wish to upgrade a stand-alone DM24 or a DM24 embedded in a *TD instrument, please skip to "Upgrading without an EAM".

Automatic Upgrades

If you have an EAM or a system which contains an EAM, the EAM can be used to automate firmware upgrades of attached or integrated digitisers. This is the easiest and safest way to upgrade a DM24.

You should also use this method if you have a DM24SxEAM, a DAS-Sx, a 3TDE, a 40TDE or a 5TDE instrument.

The latest version of Platinum software always includes the latest DM24 firmware so, first, ensure that your EAM's firmware is up-to-date - see the release notes for Platinum firmware for details. Connect your DM24 to the EAM if necessary and then, from the web interface, visit the configuration page for the digitiser. If an upgrade is available, this page will notify you and a check-box near the bottom of the page will allow you to upgrade the firmware on the DM24 when the page is submitted.

If you prefer to use the EAM's command line, please see section 8.2.3 of the Platinum manual for details of the dm24-upgrade command-line tool.

Upgrading without an EAM

Loading firmware takes place in the bootloader environment, which does not properly support 230,400 Baud operation. There have also been rare reports of upgrades failing at other, high Baud rates. If Port 0 is set to a line speed higher than 38,400 Baud, we recommend reducing the line speed to at most 38,400 Baud before proceeding. Both ends of the serial link need to run at the same speed so you may also have to reconfigure Scream or your terminal emulator. The line speed can be safely reset to the original rate after the upgrade.

You can update the digitiser firmware using any terminal program which supports the X-modem protocol, such as minicom (for Linux users), ExtraPuTTYExtraPuTTY is an extension to Simon Tatham's free (both as in “free speech” and also as in “free beer”) and highly-recommended PuTTY software, an SSH client, telnet client and serial terminal emulator that runs under Windows and Linux. In addition to all the features of PuTTY, ExtraPuTTY provides x-modem, y-modem and z-modem file transfers over serial links. ExtraPuTTY can be downloaded from SourceForge's ExtraPuTTY page. or Scream!.

To install this firmware using Scream!:

  1. Right-click on the digitiser’s icon (Scream digitiser icon) in the main window and select Terminal from the pop-up menu:

    Scream terminal menu

    A terminal window should open. Check that there is two-way communication with the digitiser by pressing enter. The digitiser should reply with ok on a new line.

    scream terminal window
  2. Type re-boot to reinitialise the digitiser,

    scream terminal window, showing reboot command

    and confirm with y. As it is restarting, the digitiser will report its status over the terminal connection, followed by a maintenance menu. (The first few lines will scroll of the top of the screen so it is presented here in text form.)

    If you do not press a key in the next five seconds, the digitiser will start up normally. If you want a little more time to read the menu, press the space-bar and the time-out will be increased to thirty seconds.

  3. Look in the boot-up messages to find the version of the boot loader you are currently using. It will be reported in a line like this:

    Guralp Systems Ltd - ARM-BOOT v3.0 mgs 13/12/12 (Build _02)

    In this example, the current boot loader is version 3.0, build 2.

    If the boot loader in the firmware package is newer than the version you currently have installed, you will need to update it first. Press b at the maintenance menu to do this.

    You will be asked for confirmation: press Y to proceed. You will then be asked to select a file transfer protocol. Press X to specify the X-modem protocol.

    The digitiser will then request an X-modem file transfer.

    • If you are using Scream!, a file browser window will appear automatically:

      Navigate through the directories on your computer and select the file to be uploaded, or type in its full path and file name. Click the 'Open' button to proceed.

    • If you are using a different terminal emulator, you may need to manually initiate an X-modem upload at this point.

    Whilst the file is loading, a progress window will be displayed. Depending on the speed of the link, it may take several minutes to transfer the bootloader.

    When the transfer is finished, you will be asked if you want to
    Reboot to run NEW BootLoader Y/N?
    It is essential to respond with a y before proceeding to the next session. Failure to do so may cause your system to become unusable.

    Once the system has rebooted, the maintenance menu will appear again. If you do not press a key within five seconds, the digitiser will start up normally. You do not want it to do that so press the space-bar: the time-out will be increased to thirty seconds, allowing you time to read the next instructions.

  4. The next step is to update the system program.

    It is essential to ensure that the boot loader is up to date before proceeding with upgrading the system program. If in any doubt, please contact for advice before continuing.

    To update the system program, press s at the maintenance menu. The digitiser will display the message Updating Application and then prompt you for your choice of file transfer protocol. Press X to specify the X-modem protocol.

    The digitiser will then request an X-modem file transfer.

    • If you are using Scream!, a file browser window will appear automatically:

      Navigate through the directories on your computer and select the file to be uploaded, or type in its full path and file name. Click the 'Open' button to proceed.

    • If you are using a different terminal emulator, you may need to manually initiate an X-modem upload at this point.

    Whilst the file is loading, a progress window will be displayed. Depending on the speed of the link, it may take up to twenty minutes to transfer the system code. Once the file is fully transferred, the digitiser will return to the maintenance menu.

  5. The next step is to update the DSP code.

    It is essential to ensure that the boot loader and system program are both up to date before proceeding with upgrading the DSP code. If in any doubt, please contact for advice before continuing.

    Look in the boot-up messages to find the version of the DSP code you are currently using.

    DSP Code : 0103:0000 dsp1091.bin loaded 2016-09-29 Default 0104:0000 dsp1081.bin loaded 2016-03-16

    There are two slots available for DSP code. In this example, the version in use is dsp1091.bin, i.e. version 1.091.

    If the DSP code in the firmware package is newer than the version you currently have installed, you will need to update it. Press D at the maintenance menu to do this. The digitiser will reply with

    Enter 0/1 to select DSP code to update

    Press <0 or 1 to specify which of the two DSP code slots you want to overwrite, and then press enter. The default is slot 0. This is the recommended slot to use unless you are performing diagnostic comparisons. The digitiser will then prompt:

    Enter Filename/date – upto 31 characters

    You can enter a descriptive string for the particular DSP code here. The digitiser will print this string at every boot-up, to remind you which version of the DSP code you are using. It is advisable to include the version number and the upload date. If you leave this blank, the original file-name will be used.

    You will then be asked for your choice of file transfer protocol. Press X to specify the X-modem protocol.

  6. The digitiser will then request an X-modem file transfer.

    • If you are using Scream!, a file browser window will appear automatically:

      Navigate through the directories on your computer and select the file to be uploaded, or type in its full path and file name. Click the 'Open' button to proceed.

    • If you are using a different terminal emulator, you may need to manually initiate an X-modem upload at this point.

    Whilst the file is loading, a progress window will be displayed. Depending on the speed of the link, it may take up to three minutes to transfer the DSP code.

  7. When the upload is complete, the digitiser will reprint the maintenance menu. Press the enter key (without selecting a menu option) and the digitiser will respond with

    Invalid command - Starting System

    and then proceed to boot up using the updated firmware. Exit your terminal emulator in the normal way; In Scream!, you only need to close the emulator window.

2011-07-01 : v.106 build 55m + DSP v10.86 + Build 11 of the v2 bootloader
  • Fixes a problem where the ‘C’ stream (calibration return) sometimes appeared as ‘X’
  • Fixes a problem where using only very low sample rates (1sps) could trigger reboots via the watchdog timer
  • Adds support for other GPS receivers (e.g. GLONASS) which require higher Baud rate. This is specified as gps-type 4 and requires use of the 1 xxxx baud command to configure Port1 to the correct speed. The system will automatically report a problem if NMEA is not detected.
  • Improves system performance regarding interrupt response and timing control
  • Fixes a possible problem of spurious resynchronisation on GPS power cycle
  • Fixes setid and resetlabels to correctly restore default Z,N,E,X labelling
  • Adds n StrongMotion command to address lowlatency/SI configuration issues. The command takes a single numeric parameter ; 0 for off, 1 for a three-component system, 2 for two three-component systems.
  • Removes incompatibilities between original SoH and ModularSoh
  • Adds ‘BytePipe’ mode for packeting arbitrary data stream into GCF format

  • Adds support for newer Flash memory chips.
2010-05-24 : v.106 build 46
  • Provides fixes for unified status reporting of the clock difference flag (the algorithm now uses a fixed drift rate of 0.07µs/s when the clock is unlocked).
  • The GPS NMEA parser now understands $GPGSL sentences from a Guralp central timing facility (RTM), and correctly passes through information about the RTM’s GPS fix and drift to the DM24.
  • Fixes a problem which affected the broadband calibration facility (. RANDOMCAL).
2010-02-16 : Build 7 of the v2 bootloader
  • Fixed a problem which could occur during an update from v1 Boot when a new system fails to load correctly: the session will now stay at the boot menu until a valid system code update occurs.
2010-02-01 : v.106 build 42
This release was recommended for all Mk3 DM24s other than those with USB support, for which the latest v.103 build should still be used.

  • Adds support for 6/7 channel system with variable gain input stage.
  • Added short mux channel blocks for CD1.1 – 10 secsmux.
  • Added flush-flash command to ‘empty’ flash file. Use in preference to reset-flash: flush-flash simply sets the read pointer equal to the write pointer so the buffer is ‘empty’ – the data are still available until it is overwritten by wrapping round and the system continues to write from the current position.reset-flash resets the pointers back to the start so the old data gets overwritten straight away. The system uses the early part of the buffer more which is to be avoided in terms of durability (wear levelling).
  • Bug fixes :
    • %auto-centre rounding problem fixed
    • Improved handling for non-standard Baud rates
    • Scream TCP now reports version 4.5
    • .info command restored
    • Y/N handling of control chars
    • FireWire updated to handle full FAT size – 511 entries (as v103b70)
    • TCP/IP MSS issue fixed
2010-01-12 : v.103 build 82
  • This addresses issues with the accuracy and repeatability of data time-stamping and synchronising. Initial synchronisation to GPS has also been improved.
  • When updating from earlier firmware, the timing parameters will need to be reset using
    ok-1  0 [pwm] ! [pwm] nv! 59920 bias ! bias nv! $06010F dspsync ! dspsync nv!

    Newly manufactured units will be loaded with the correct defaults when initially run.

  • DSP1070 also addresses some potential problems for timing discrepancies between streams.
  • USP status now reports ‘calibrating’ for ‘ALL’ and the GPS sync/lock correctly.
  • GPS synchronisation always occurs after a startup/reboot – initial sync is better than 15 microseconds (this avoids a trim operation to align the clock from an initial 10 millisecond error, which would take a significant time, during which data would be inaccurately stamped).
2009-05-13 : v.103 build 78
  • Adds USB host support for memory sticks and improved trigger selection.
2008-06-30 : v.103 build 70
  • Properly handles GSL Disk filing – maximum 510 entries. Reports after transfer when insufficient space (number of files or free space) is left for next transfer and disables auto operation. Also advises when transfer size will result in more than 510 entries so disk capacity not fully utilised. Example status messages:
      2008  6 12 10:38:45 Data Ready to Transfer
      2008  6 12 10:41:25 Data Transfer Complete
      #Entries:  83 of 510
       Capacity   1.2GB        Used   1.0GB   Available 200.9MB
      Not enough space for next transfer   4.1GB FireWire Buffer
    
      2008  6 12 10:50:32 Transferring  30.0MB to Disk

      #Entries:  84 of 510
       Capacity  19.5GB        Used   1.0GB   Available  18.4GB
      FireWire buffer too  small for optimum  disk usage *****
  • Added PGA alarm setting, which operates on relay 1/3 on STA-DISP interface module (SI alarm is on relay 0/2). Use command SetPGAalarm to set the level in gal.
    Function of outputs on STA-DISP interface module.
    Measurement Current loop output Relay output Sensor
    SI 0 0 Sensor A
    PGA 1 1 Sensor A
    SI 2 2 Sensor B
    PGA 3 3 Sensor B
  • Added LLstreams disable to suppress output of data streams, so that only strong motion computed values are output. Use LLstreams enable to return to previous operation.
  • Added extra trap for baudrates divisible by 1200 to baud command. Use the new Forth command [baud] for other rates.
2008-05-23 : v.103 build 68
Fixes ADC sync problem, for both doesn’t stop and doesn’t start on GPS sync (fixes problem where timing could be 1 second out without any indication in status). Added support to switch between unified status and CD status. Defaults to CD status; use uspmonitor to re-enable unified status packets.
    2008-02-13 : v.103 build 65
    Addresses problem with undetermined SOH control line selection during startup. Initialises cal relay twice. Addresses issue of erroneous X channel selection. ADC sync failure does not re-boot, but instead forces another sync sequence. Fixed power switching of borehole SOH I2C. Added SetTriggerLevels (protected) for real-units setup of level triggering.
      2007-12-18 : v.103 build 64
      Updated firewire operation to allow multiple DMs to access a single disk on the same FireWire bus. Increased watchdog timeout. Flash bad block scan limited to 250 max.
        2007-10-30 : v.103 build 62
        Modified default modem init string (removed &H0 part). Remove spurious characters during setmodem$ command interaction.
          2007-10-26 : v.103 build 61
          Modem code now has configurable modem initialisation (command setmodem$). +modem supports option for ‘dial-in only’ mode.
            2007-10-17 : v.103 build 60
            Fixed bug in modem code.
