debug error with stm32h755 on cube ide

[Ruồi]

I configured adc+dma of h755 on cubemx and generated code for cube ide.
I compile (have not changed the code since it was created) and it's normal.
However, when debugging, it runs to this line and cannot exit.

H755 board is NUH755ZIQ$AT3, while I debug on NUH755ZIQ$AT1 and it's normal.

Thanks for any solution

Hello,

Have a look at his thread: https://community.st.com/t5/stm32cubeide-mcus/stm32h755-nucleo-m4-core-debugging-problem/m-p/650982

Hello,

my problem lies in the fact that it cannot escape while((__HAL_RCC_GET_FLAG(RCC_FLAG_D2CKRDY) != RESET) && (timeout-- > 0));
I looked at your suggestion but none of the solutions worked.

Thanks

I run it on AT1 board with no problem.
But running on AT3 board, I get this error. Is there any difference between the two nucleo boards H755 AT1 and AT3?

The solution is to load the code for CM4 first and reload the code for CM7 to solve this problem.
