  • [ABANDONED] Ozone STM32MP1 Coprocessor debugging

    Hi there,
    I am trying to debug the Cortex-M4 coprocessor of a STM32MP1 multi-core micro using Ozone, but connecting to target fails. Here is the console output:

    Debug.Start();
    Device "STM32MP15XX_M4_DUALFLASH" selected.
    ConfigTargetSettings() start
    ConfigTargetSettings() end
    InitTarget() start
    J-Link script: InitTarget()
    InitTarget() end
    TotalIRLen = 9, IRPrint = 0x0011
    JTAG chain detection found 2 devices:
    #0 Id: 0x6BA00477, IRLen: 04, CoreSight JTAG-DP
    #1 Id: 0x06500041, IRLen: 05, Unknown device
    Failed to power up DAP

    I did setup an empty Ozone project with a simple "Hello World" program and selected the "STM32MP15xx_m4_dualflash" as device, but it seems that I missed something... Does anyone can tell me the correct settings for accessing the M4 core insight the STM32MP1?

  • Hello Karsten,

    Thank you for your inquiry.
    Are you using custom hardware or an eval board?
    You can find an example project for the STM32MP15X-EVAL on our Wiki:
    wiki.segger.com/STM32MP15x#Tracing_on_STM32MP15x

    Could you give the TMC/ETB trace sample a try?

    Does it work for you as well?


    If not could you check the following troubleshooting steps and provide a screenshot of the Commander session?

    Best regards,
