Hy folks!

I have a problem with a STM32Discovery board, after a wrong programmation seems impossible to recover the board.

I follow exactly this procedure:

in switch off state connect the Boot0 Pin to 3v

then i switch on the board

now i try to erase the memory using the flash loader demonstrator (via USART1 PA9 and PA10)

when i try erasing the tool says that there are a reading protection...

i try using IAR, via usb, clicking Project->Download->Erase memory

but it says that there are no MCU

Can you help me. please

Perhaps then you need to look at what happen to the ''Option Bytes''

If you get these set wrong, it will enter various read protection modes, some irreversible.

You could look to see if the Flash Loader Demonstrator can address these in the F0 boards (I assume this is what you're using, but you should be specific about which Discovery board we're talking about). The other would be to see if the ST-LINK utilities will resolve this.
