#181270 - Often special lock bits for boot regions Responding to: ???'s previous message |
Andy Peters said:
Flash protection? Yes, but the firmware update program necessarily sets those to write-allowed.
-a Many processors have multiple flash protect bits for different flash areas, so that the boot loader can be protected even when the normal code space gets erased. Some chips even have so strong protection of a boot area that they can lock the lock bit making the boot loader incapable of accidentaly clearing its own lock bit. |
