  • Hi,


    which version of the J-Link software do you use?
    Do you specify the device (iMX31)?

  • Hi,

    Could you please post a screenshot of J-Link Commander after following these instructions?:


    • Start J-Link Commander (jlink.exe)
    • Type "connect" in order to start a debug session
    • Type in the target device name if asked (Or type "?" for a target selection Dialog)
    • Choose the correct target interface (JTAG/SWD/etc..)
    • Use a valid speed (Default: 4000kHz, try 100-500 if default does not work)
    • [JTAG only]JTAG conf can be default(most of the times)
    • You should now be successfully connected.
    If anything fails, could you please post a screenshot of the complete session?

    Best regards,
    Niklas

  • Hi,


    from what I can see, the connect is successful.
    In order to confirm this, you could e.g. try to read memory using the mem32 command.
