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?
