STM32H755 dual core debugging problem

Good morning:

Please I would like to receive your help.

I am starting to learn to program the STM32H755 microcontroller using a nucleo board and the STM32CUBE IDE tools.

My first project is to blink two leds using individual CPUs. That is, the green LED with the M4 CPU and the red LED with the M7 CPU.

After configuring the debugger, the system only programs the M4 CPU and additionally the algorithm runs very slowly.

Please, I would appreciate your valuable help on this issue.

Thank you

    Hello again  @JUANdeJESUS 

    There are some suggestions in order to troubleshoot your issue :

    1-In debug configuration check "Halt all cores" in reset behavior

    2-Go to the Startup tab and select [Edit…]>[Disable Download]. This is required since the download is already
    performed by the Cortex®-M7 configuration

    3- You can launch the debug session on both cores with only one launch configuration as shown below

    Hello @JUANdeJESUS and welcome to the community!

    I recommend you this document AN5361 , which can help you in debug configuration with STM32H7.

    Thank you,

    Souhaib
