Abstract
Devices include a processor and a memory. The processor is configured to determine if a bootloader area does not contain a valid bootloader instruction set, to locate a bootloader instruction set, and to copy the bootloader instruction set to the bootloader area. The processor then executes the bootloader instruction set from the bootloader area.
Claims8
A device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- determine that a bootloader instruction set in a designated bootloader memory execution location in a memory does not contain a valid bootloader instruction set,
- access a replacement bootloader instruction set from a predetermined location in the memory;
- store the replacement bootloader instruction set in the designated bootloader memory execution location;
- validate the replacement bootloader instruction set utilizing a bootloader signature;
- and
- execute, the replacement bootloader instruction set from the designated bootloader memory execution location.
