  • [SOLVED] J-Trace Pro Firmware Update & Firmware Restoration fail

    Dear Sirs at Segger,

    I just downloaded the JLink package for Windows V6.82.

    As soon as I tried to connect my J-Trace Pro to the IDE, the prompt came up to update the firmware, which I have always done without any glitch.

    But this time was different. Don't know how, but something went wrong with the update procedure.
    Now, when trying to connect to the probe (e.g. from the command-line JLink) this message pops up:

    "The firmware of the connected J-Link will now be restored.
    The connected J-Link is running in bootloader mode. This happens if no valid firmware has been found on the J-Link.
    Without a valid firmware, J-Link cannot be used."

    The restoration process seems to conclude successfully, saying "Firmware updated successfully".
    But after connecting the J-Trace probe, the firmware restoration message appears again.

    I tried to use the J-Link Configuration tool, but the probe is not listed in the USB panel.
    If I connect it to the Ethernet, then it appears in the TCP/IP list. But when trying to update it from here (right-click) I get the message:

    "Error, Failed to open DLL".

    Now I am really stuck, with my J-Trace no longer usable. :(

    Thanks for any help
    Giuseppe
  • Hi Giuseppe,
    Thank you for your inquiry.
    Such an issue is not known to us.

    Could you please try the following:
    1) Open the J-Link Commander (JLink.exe/JLinkExe)
    2) Connect to the J-Trace PRO Cortex-M that is stuck in bootloader mode (if the J-Trace is the only probe connected to your PC, this happens automatically)
    3) Issue the following commands:

    Source Code

    1. exec invalidatefw
    2. usb
    This will
    1. reset the firmware of the J-Trace and
    2. then update the firmware again.

    Does everything work as expected after these steps?
    If it does not, could you please send us a screenshot of the full Commander output?

    Best regards,
    Fabian

  • Thank you Fabian, for your prompt reply.

    As soon as I connect the J-Trace Pro to the USB port, I get what you see in pic1.png.
    I press O.K. to restore the firmware, then I get pic2.png.
    When closing the dialog and return to the command prompt, I see what is in pic3.png
    Now there is no way to give the command you suggest me:


    exec invalidatefw


    as soon as I try, the first pop-up (pic1.png) appears again.
