Abstract
A data repair and synchronization method of dual flash ROM is provided, which includes a first flash ROM and a second flash ROM that store the same system data, wherein one of the first flash ROM and the second flash ROM is used to perform a data repair on the other flash ROM with damaged data and perform a data synchronization between the two flash ROMs, thereby ensuring that once the data in one flash ROM is damaged during the system operation, the complete system data stored in the other flash ROM is used to recover the damaged operating system and the files in the system. Meanwhile, through performing the data synchronization periodically, important configuration files in the system stored in the two flash ROMs are kept to be updated and completed.
