  • Hi,

    thanks for your inquiry.
    the "-" values indicate that flash programming of this target device is not yet supported by J-Link, but the device can be selected and debugged with the current version.


    Best regards,

  • Hello Nikla,

    thanks for the explanation.
    Official support for this Titan device is very welcome.
    So far there were no problems with the internal flash programming.

    The question just showed up with J-Link 5.10+ software because our scripts did not give the device in the expected order
    and the "Unspecified" -> please select.. appeared, both with MB9DF125 and MB9EF226.

    When beeing in
    "C:\Program Files\SEGGER\JLink_V510c"
    and running

    Source Code

    1. JLink.exe
    2. -If JTAG
    3. -Speed 25000
    4. -Device MB9DF126
    5. -CommanderScript atlas_l.jlink
    6. -JLinkScriptFile Samples\JFlash\ProjectFiles\Fujitsu\MB9DF126.JLinkScript


    where the commander script is

    Source Code

    1. loadbin sample.bin,0x01000000


    This now triggers a IRPre/DRPre question:

    Source Code

    1. SEGGER J-Link Commander V5.10c (Compiled Dec 4 2015 17:25:58)
    2. DLL version V5.10c, compiled Dec 4 2015 17:25:20
    5. Script file read successfully.
    6. Processing script file...
    8. J-Link connection not established yet but required for command.
    9. Connecting to J-Link via USB...O.K.
    10. Firmware: J-Link Ultra Rev.1 compiled Dec 3 2013 14:27:53
    11. Hardware version: V1.00
    12. S/N: 501200383
    13. License(s): RDI, FlashBP, FlashDL, JFlash, GDB
    14. Emulator has Trace capability
    15. VTref = 4.588V
    16. Target connection not established yet but required for command.
    17. Device position in JTAG chain (IRPre,DRPre) <Default>: -1,-1 => Auto-detect
    18. JTAGConf>
    Display All


    when adding the [code]Config 0,0[code] in first line of the commander script
    i get the Device Selection message "The selected device "UNSPECIFIED" is unknown to this version of the J-Link software..".

    What is the correct sequence to automatically conncet here?
    Is there some equivalent command line option for the Config command?

  • no not solved. It seems i can not avoid the JTAGConf> prompt,
    even when doing "config 0,0".

    Source Code

    1. si JTAG
    2. speed 25000
    3. exec Device CORTEX-..
    4. config 0,0
    5. Device CORTEX-..
    6. connect


    results in

    Source Code

    1. Cortex-.. identified.
    3. Device position in JTAG chain (IRPre,DRPre) <Default>: -1,-1 => Auto-detect
    4. JTAGConf>

  • Hi,

    Sorry for the delay in response.
    Could you try to invoke J-Link commander with this command line instead of setting the parameters in a commander script?
    jlink.exe -device MB9DF126 -if JTAG -speed 25000 -JTAGConf -1,-1 -AutoConnect 1

    >>config 0,0<< does not set all variables required. We will fix this behavior in future versions of the J-Link software & documentation pack .

    Best regards,

  • Hi all,

    A new version of the J-Link software (5.11a), which comes with flash programming support for MB9EF226 is planned to be available later today.
    The version will be available for download here: segger.com/jlink-software-beta-version.html

    Best regards

  • I have installed JLink_V510g, and

    Source Code

    1. JLink.exe -If JTAG -Speed 25000 -Device MB9EF226 -JTAGConf 0,0 -AutoConnect 1 -JLinkScriptFile .... -CommanderScript ...

    works very well now, and does no longer prompt for any device or JTAG position.
    Many Thanks!

  • Thanks for confirmation and good to hear that you are up and running now!
