Hello,
I use a STM32F405 in a design.
I have a test softaware for the board to ttest GPIOs, CAN,...)
It was working well, but suddenly nothning work at all (also functions that was working before).
I try to reflash my program, but the flash memory seems to be locked.

Can the CPU be locked (protected)?
How can I unlock my STM32 and recover full operational working mode?
