I'm using BF706 for my project. I was able to read the Factory Serial Number from the OTP memory using the function below:
However, after I locked the processor, I'm getting the error below when using the function above.
A non-recoverable error or exception has occurred.Description: Attempted to use a Supervisor register or instruction from User mode (Exception with EXCAUSE=0x2E).General Type: UnhandledExceptionSpecific Type: SupervisorResourceError PC: 0x04003ad2
May I know:
1) Is there any restrictions on querying the OTP memory data after processor is locked?
2) How I get rid of this?
