Power Loss Vulnerability in System ROM Firmware Update Process

Revisions Affected

E

Details

The firmware update process, including HSM, Secondary Bootloader, and application updates, executed by the System ROM may be unexpectedly interrupted if a power loss occurs during operation. Since the ROMAPI register is not retained across power cycles, the System ROM is unable to resume and complete the firmware update process.

Workaround

None. The permanent fix is to use Silicon Revision PG2.1 (Rev F).
