4.3.1.1 Recovery (Mutable Recovery Image)

Most of the recovery options listed in Assets include methods that require a section of memory that can be both updated and protected from modification. The Flash protection region feature supports the run-time control needed to protect against a corrupted image from execution, protects the corrupted image from modification until it can be extracted for analysis and protects the recovery image from modification unless authorized. Recovery from the Latest Firmware Version, Dedicated Recovery Image and Image Swapping represent a few examples of possible recovery implementations and how the Flash protection regions can facilitate the security objectives.
