STM32N6 flash failed to erase memory

Brenden_PLUS · ‎2026-02-05

I have a STM32N6570-DK and i can't seem to program it any more. I tried it in both the STM32 programmer gui and terminal application. So i can connect to the device read and read the flash but i can't seem to write to it any more. I can't even erase the flash. I have another

Boot 0 = 0 (L)

Boot 1 = 1 (H)

So i wish i could give you more info, but my board just stopped working for some reason it seems like.

Used to work
I bought a new STM32N6 DK and that one works.

but i don't know what could have caused it to not be able to write to the flash?
