STM32N6 flash failed to erase memory

[Brenden_PLUS]

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)

Hello @Brenden_PLUS ,
Could you please provide any other information that may help investigating this? I've tried doing this sequence with a similar setup and it worked on my end.

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?

Closing this.  It did just start to work again.  Don't know what changed
