Hi to everyone,

I'm working on STM32F411 and I'm wondering if it's possible at the start of a code, detect if a new flash code is in progress to stop the code execution and wait for the flash. This strange problem is due to working with a code continuosly updated and flashed; I'd like, when my board powers up, that the code execution stops if it detects that I'm flashing a new code. Is it really possible or it is only a dream ?

Kind regards

Davide Urbano

No, it's not.

Your MCU has only one Flash bank, and any code execution from Flash stalls while an erase/program is in progress.
