i am using STM32L4S5 series controller which contains 2MB flash. recently I got a problem like Read out protection activated. Because of that i am not able to read write as well mass erase also. And then i read the options registers from 2 boards (one is not working board and one working board). I have attached these option registers. Please check what could be the issue. The problem is i am not able to reprogram anything on FLASH even if i do power off and ON.
