I'm using a stm32l151cct6 MCU and I want to protect a sector of the flash memory using Option Bytes in ST-LINK Utility.

When I try to use the mode 'write protection', the application code works fine. When I try to use the mode 'read/write protection', it seems that the selected sector memory is erased and the application code don't work.

How I can solve the problem please?

Thanks.
