  • [SOLVED] Halt on Connect

    How can I get debugger to halt on connect?
    I have a code hang and want to check where it's spinning?

    Segger Embedded Studio for ARM V5.68

    Thanks,


    More to my issue; code/system behaves fine when debugger is connected; but seems to hang up if debugger not connected. In such a hang; connecting the debugger seems to let the processor run again from where the hang was.

    I am suspecting a RTT related issue; I am using three sets of RTT buffers; all of which should be skip/no block. But I am suspecting the connect of the debugger is flushing the buffers and therefore letting the target proceed. I am sure there used to be an option to let one halt on connect or am I thinking of IAR.

    I can connect using Jlink commander and halt; but then I don't have the facility of a nice stack backtrace.

  • Hi,
    Thank you for your inquiry.

    There is no such option in Embedded Studio (ES).
    You can however use Ozone, which offers attach & halt.

    If this is actually related to RTT, I would suggest to recheck your buffer configuration.
    You can also disable RTT handling in ES and close all applications using RTT.
    In such a case, RTT would not be activated on attach, and your application would still hang in the print routine,
    as the buffers are not emptied.

    Please note:
    Some targets have a reset as part of the device specific connect.
    This reset is currently also executed when attaching to the device.
    In such a case, the reset might also be the reason for the application to stop hanging.

    Best regards,
    Fabian
