  • Can't connect to STM32-SK via IAR J-Link

    Hello,

    I'm trying to connect to a CortexM3-based development board, the STM32-SK, but I'm having some problems.

    Here's the output of the J-Link commander:

    I think that I created some problem experimenting with OpenOCD, I'd like to reset the board.

    Can anyone help me? Thanks.

  • Can you try the latest Beta to see if it behaves differently ?
    Do you have any other eval board to see if you can connect ? (Maybe the J-Link or target board has a hardware defect)

    What is strange is that J-Link can not pull RESET low. Can you check if the RESET line goes low when you use
    the command r0 ?
    If not, it may explain things: The STM32 may be in power down mode and needs a Reset, but it never gets a Reset
    because Reset line does not go low.

    Just guessing, maybe you can test this ?

  • Hello,
    I tried to connect the STM32-SK using another PC and it worked correctly.. I used the JLink software that comes in bundle with the IAR embedded workbench, here is the output:

    Can it be an issue related to the PC I was using? Maybe the USB controller...
    Anyway, thanks for your help.

    Have a nice day,
