We have a problem with disable a Read Flash protection inside our application with the STM32F103RG.

We arrive in a situtation that the flash memory entire in a Read Protection state because there was a power supply failure. After a power reset, the system is in Flash Read Protection and we would like to disabled this protection without Flash Loader software and without to do an erase mass.

How can we do that ?

Can everybody help us ?

Thanks,

I'm not wholly convinced you can get the part in ROP using the method you describe.

You will however need to mass erase the part to remove ROP.
