Hello !


I can see in UM that CPMA can be sealed and not possible to update it any more.


But what about other flash memory areas ?

Can some areas be written once only and protected from erase some how ?

Or application can set some protection to flash memory and next updated is not able to remove it ?


is this possible ?
