Error: failed to erase memory

[SRebe.1]

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:

Hi @SRebe.1​ ,

is erasing of the external memory working using other means such as the MCU code or a compatible programmer?
