    • 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:

      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:

      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?
