Re: EEPROM STM32 is now read only

ok, so ! i've connected my stm32 to the stm32cubeprogrammer and i've seen that all the flash was not protected. so as you said, the problem dont come from this point. after that i tried to re upload the same bootloader (just in case) but it not changed nothing. finaly, i found this video : https://w...

have i to re-upload the originla bootloader ?
thank you
