Abstract
A system and method for firmware updates on Execute-in-Place (XIP) devices with multiple memory partitions is disclosed. Firmware files include instructions coded to one of the partitions, while another partition runs the active firmware. An address remapping technique redirects the fetching addresses in the instructions to the partition storing the active firmware, so the instructions may be executed properly when the firmware files are installed in either partition. As a consequence, the firmware update file only requires one version, instead of multiple versions for multiple partitions, and this simplifies the firmware update process, such as compatibility verification and version control, saves memory space on the server, and reduces bandwidth usage.
