STM32MP157 DK2 M4 debug issue

fantasylsdo · ‎2023-09-20

Dears,

I'm using STM32MP157C-DK2 board in production mode.

Now I'm debugging the firmware in M4 core. However, when I insert a breakpoint at DMA interrupt handler and wait for a while, it will crash the whole system (A7+M4) and lead to the reset.

I also tried the example SPI_FullDuplex_ComDMA_Master. It still has the same issue.

Do you have any resolution?

Thanks for your help in advance.

Hi @fantasylsdo ,
Maybe a watchdog not set to be stopped in debug state ?

Maybe look at DBG section of RM0436 Reference Manual.
