  • [ABANDONED] Starting bootloader... already started.

    Good day,

    I upgraded STM32CubeIDE to version 6.1 which then also indicated that the J-Link pod need to be updated which I duly did. Unfortunately the update process failed and now the J-Link is stuck in bootloader mode. I can't get the J-Link to upgrade using J-Link Commander (J-Link.exe) or J-Link Configurator (JLinkConfig.exe). Each time I start either of the pervious applications I get the following pop up window:
    "
    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.
    "
    When I click OK the SEGGER J-Link V7.50a Firmware Update window opens a the following is displayed:
    New firmware: J-Link V9 compiled May 7 2021 16:26:12
    Current firmware: J-Link V9 compiled Oct 12 2012 BTL
    Starting bootloader... already started.
    Sending firmware data...

    Unfortunately nothing happens and the progress bar stays at 0%.

    I have tried to uninstall J-Link and the driver for the pod and reinstall but I get the same result. I even tried to go back to V6.14h and try with an older version as the pod is a few years old, but I get the same result, it hangs doing the update.

    PS. I have tried both the 32-bit and the 64-bit version of J-Link.

  • Hi,
    Thank you for your inquiry.

    Did you try to change the USB cable + connect the J-Link directly to a USB port of you PC?
    If so, it is most likely that your J-Link is no longer functional.

    Could you please tell us the SN of the damaged J-Link?
    If you are concerned about sharing it publicly, feel free to send me a direct message with the SN.

    Best regards,
    Fabian
