Field update of boot loader using regular device firmware update procedure
Abstract:
Embodiments of the inventive concept include a boot loader update firmware (305), a system and method for producing the boot loader update firmware (305), and a method for using the boot loader update firmware (305) to update a boot loader module (160) in a device (110, 205, 210, 215). The boot loader update firmware (305) can include logic (310) to install firmware (315) in non-volatile memory (145). The firmware (315) can include a binary image (320) of the updated boot loader module (160). When the device (110, 205, 210, 215) is rebooted, the firmware (315) is activated, which can then copy the binary image 320) into non-volatile memory (150). When the device (110, 205, 210, 215) is rebooted again, the updated boot loader module (160) is activated.
