Is there any way to read the program once IFR region with a debugger? Can the debugger tell the flash module to execute the Read Program Once Command (Assuming the device is un-secure)? For security reasons, external access to this region is unacceptable in our application.
MCU: MK22FN512
Debugger: Any
Thanks,
Partly answered my own question.
Even if the debugger could not read that region,
If security is a concern, someone could issue a mass erase command and put their own program on their to read the IFR region themselves. So we will not be doing this.
