Hello there
I was trying to debug my stm32h750 with an stlink-v3 mini. I'm currently working with an external flash as my code area. The bootloader and external loader worked before, but suddenly I can't load code on my external flash. Does anyone know why this happens?
This is the error I receive when trying to debug:
