  • [ABANDONED] segmentation fault on linux ARM

    Hello,

    I'm getting a segmentation fault execption when running the same test multiple times. It works well for the first tests, and then fails with this segmentation fault.
    Probably out of scope, but the target is a tms570lc4357 from TI, and the probe is a JTrace Cortex Pro.

    Attached the output log generated during execution of the test.

    I can reproduce the behavior with both version 6.90a and 6.96.

    Don't know if it helps, but I had a similar issue a few years ago, here is the thread: [SOLVED] Segmentation fault: 11 exception when connecting/disconnecting gdb multiple times

    Thanks in advance for your feedback and regards,

    Guillaume

  • Hello Fabian,

    Sorry for the delayed answer. I guess the steps to reproduce are available in the log file joined in my previous post?
    Let me know what you are expecting to receive from my side otherwise

  • Hi,

    Actually the “log file” you provided is not a log file. It is just the output of J-Link that happens during connect etc.
    It does not show which functions you call or what commands you pass to JLinkExe.
    How to get a log file:

    Can you please get us such a log file?

  • Hello Alex,

    Sorry for the late answer. Attached the full log, as requested.
    The evaluation board is the official HDK from TI (tms570lc4357). The probe is a J-Trace Pro (v1).
    Worth mentioning the host is a Raspberry Pi 4B revision 1.4.

    Please let me know if you need more information from my side.

    Best Regards,

    Guillaume

  • Hi Guillaume,

    Thanks for providing the log file.
    I do not see anything in the log file that indicates a crash / segmentation fault.
    The connection to the device is established, followed by a very loooong sequence of
    IsOpen()
    IsConnected()
    IsHalted()
    calls.
    In the end there is a Close() call and the log file is cleaned gracefully at the end.
    If a segmentation fault occurs, I would expect the software to crash somewhere, so we should see the log to stop abruptly, even in the middle of any API call etc.

  • Hi Alex,

    I sent you the wrong file, sorry. It appear to fail in function JLINK_DEVICE_GetIndex, as shown in the log bellow:
