Abstract
A system-on-a-chip includes a first memory and a processor. The first memory is configured to store a boot code. The processor is configured to (i) access the first memory, and (ii) execute the boot code when booting up. The processor is configured to, while booting up, determine whether a first one-time-programmable memory has been previously programmed based on the boot code. The processor is configured to, in response to the first one-time-programmable memory not having been previously programmed based on the boot code, (i) load firmware from a second memory into a third memory, and (ii) execute the firmware loaded into the third memory. The processor is configured to, in response to the first one-time-programmable memory having been previously programmed, verify a digital signature of the firmware.
