COMMUNICATION MODULE SOFTWARE UPGRADING METHOD AND SYSTEM, AND COMMUNICATION MODULE

摘要

Disclosed by the present application are a communication module software upgrading method and system, and a communication module. The method comprises: generating a differential package of the entire firmware according to source firmware before upgrading and target firmware after upgrading, that is, generating a differential package for the bottom-layer encoding of the entire firmware, rather than generating a differential package for each file in a file system; during module upgrading, generating complete target firmware according to the differential package and the firmware of the current file system of the module thereof, and burning the target firmware into the partition in which the firmware of the current file system of the module is located, thus implementing the overall upgrading of the entire file system. Since the firmware of an entire file system is re-burned, rather than each file in the file system being updated one by one, even if a power outage occurs during burning and the system cannot be restarted, it is only necessary to re-burn target firmware into the partition in which the firmware of the current file system is located, and it is not necessary to mount the file system, thereby avoiding the phenomenon of module system crashes.
