  • FIRMWARE UPDATING CIRCUIT AND FIRMWARE UPDATING METHOD
    Publication number: 20070169098
    Abstract: A firmware updating circuit of the present invention includes an identification part and an address inversion part. The identification part stores identification data corresponding to an address of a boot loader in a non-volatile memory for storing the boot loader and a main program. When the controller updates both the boot loader and the main program, the address inversion part changes an address for reading the boot loader, output by a controller to the non-volatile memory, and an address for writing another boot loader to be updated according to the identification data so that those addresses come to be different from each other and at least one of the boot loader and the boot loader to be updated comes to exist in the non-volatile memory.
