Flash ROM Fusing Method Of Processor Board

摘要

PURPOSE: A flash ROM fusing method is provided to normally download a header of a new firmware program via a disk or an IPC(Inter-Process Communication), and fuse only a newly updated part of the firmware program to a corresponding flash ROM. CONSTITUTION: The method comprises steps of dividing a flash ROM into a basic flash ROM and a backup flash ROM, executing a bug management program(S31), checking if a CRC in the basic flash ROM is normal(S32), executing an initial loading program(S33), checking if a new firmware program header is loaded(S34), checking if a header of a checkup program is loaded(S35), comparing the newly updated firmware program with a backup program, downloaded via a disk or an IPC(S36), fusing the firmware program to the backup flash ROM in the case that the newly updated firmware program is not identical to the backup program(S38), and fusing the firmware program, fused to the backup flash ROM, to the basic flash ROM(S39).
