STM32H757I-EVAL TouchGFX Project not uploadable with CubeIDE

[CBier.1]

I bought the STM32H7 dual-core EVAL board STM32H757I-EVAL and started with TouchGFX. I created some first buttons in TouchGFX Designer and flashed them to the board — that part works fine and runs without issues.

Now I want to continue programming in STM32CubeIDE, but I cannot start the CM7 debug session. CubeIDE shows:

• “Launching STM32H747I-EVAL_CM7 Debug has encountered a problem”

• “Failed to execute MI command: load …\STM32H747I-EVAL_CM7.elf”

• “Error message from debugger back end: Load failed”

The M4 upload/flash finishes without any error message, but it looks like the M4 application does not run. For M7, I always get the “Load failed” message above.

I followed this YouTube tutorial, but without success: https://www.youtube.com/watch?v=k3mXhPZSasw

Question: What is the correct workflow to flash/debug CM7 and CM4 on this EVAL board in CubeIDE (especially for TouchGFX projects)? Why does CM7 “load” fail while TouchGFX flashing works?

Hello @CBier.1 

You can refer to this Application Note to flash/debug CM7 and CM4 on the STM32H7 Eval board.

Could you please take a look at this post to see if it's similar to your issue?

Otherwise, try to connect your board using STM32CubeProgrammer tool and load the .elf file and check
