  • GDB + Multi-thread Awareness

    How can I use a Segger J-Link with GDB and view the state of multiple RTOS threads?

    My setup:
    * J-Link Ultra+
    * J-Link GDBServer 4.97I
    * GNU GDB client
    * STM32F207
    * ThreadX RTOS
    * Eclipse IDE

    I can connect to the MCU and debug just fine (single-step, view memory, etc). However it only shows one thread. Issuing the GDB command: 'info threads' only returns one thread as well.

    I believe my GDB client is capable of receiving thread events from the RTOS (ThreadX) as I can view multiple threads using OpenOCD. How can I view multiple threads using J-Link?

    Any insight would be greatly appreciated.


    Thanks

  • Hello,

    To view multiple threads and their information the debug server (GDB Server / OpenOCD) requires information about which OS is running and how it is handled.

    For J-Link GDB Server, there is currently no OS Awareness available, so it is not possible to view multiple threads.
    This is on our long-term todo, but with no fixed schedule, yet.

    Best regards
    Johannes
