Secure Boot ROM Emulation |
摘要 |
Secure boot ROM emulation with locking storage device. A locking storage device is provided by combining a nonvolatile memory device such as flash or EEPROM with one-shot locking logic which write enables at least a portion of the nonvolatile memory device upon power cycling of the overall digital device. This write enable is cleared during the stage 1 bootloader process, thus providing a protected update interval for updating a stage 2 bootloader once per power cycle.
