Abstract
Method and apparatus for multi-block update using secure flash memory. An update package is received at a device containing update code to update existing code for the device stored in non-volatile memory. The received update code is stored in a first portion of the non-volatile memory, while pointers identifying storage locations of respective sets of the update code are written to a second portion of the non-volatile memory device. An update process is then performed with the update code by using the pointers to locate the respective sets and assembling the update code. Updated firmware and software images are then written to the non-volatile memory device to complete the update.
