  • [SOLVED] Debugging STM32H745

    Hello,

    I am trying to debug a dual core STM32H745 with Ozone V3.30d.
    While I can flash and step thought the code on the M7, it does not work on the M4. Flashing works, but I cannot debug.
    Console output after clicking Resume:

    Source Code

    1. T-bit of XPSR is 0 but should be 1. Changed to 1.
    Subsequent Resumes result in the same message.

    Is this essentially possible with Ozone?
    What am I missing?

  • ...I missed the logic of the default STM32Cube code. M7 will timeout until I am able to start the second debug session and M4 will end up in stop-mode.
    After fixing that, now both cores are running, but halting the CPU on either Ozone instance will only stop the M4, the M7 keeps running.

    How can I halt the M7 or both at once?

  • Hi,
    Both at once:
    Executed via cross trigger.
    Not supported yet. It's on our list but without a fixed schedule at the moment.

    M7 only:
    You should be able to halt the M7 in the M7 debug session.
    If this does not work, could you please share a J-Link log file of this session with us?
