Abstract
Systems and methods for performing flash updates during runtime are discussed. More particularly, the amount of secure memory required to prevent tampering during the update process is limited by storing hashes of logical blocks of the update image in secure memory after initial validation while storing the update image in non-secure RAM or another non-secure memory location. Additionally, disruptions to the computing platform are limited by dividing the logical blocks into smaller progress units to minimize the amount of time spent in the secure operating environment performing the update.
