Abstract
A device includes a memory, a first firmware copy of the device stored in a first position of the memory and a second firmware copy of the device stored in a second position of the memory, where each of the first firmware copy and the second firmware copy includes instructions, when executed by the device, perform an operation of the device; and a first delta copy associated with the first firmware copy. The first delta copy includes instructions that differ from the first firmware copy when executed at the first position and are the same when executed at the second position. The device is configured to receive the first delta copy from an external system and store the first delta copy in the memory.
