Firmware in subregion replaces with the firmware in current system disk partition.
Further, whether the firmware content that firmware synchronization module is used to directly compare in two systems disk partition is identical.
The complete mirror image of two systems in the present invention, backups each other, and operation that can be independent simultaneously realizes embedded device
Repertoire.When a system can normally start, by the disk partition for being synchronized to another system in the system disk subregion,
Then preferentially renewal firmware is stored in the disk partition of back-up system when there is firmware renewal（Now current runtime is consolidated
Part is constant, and the firmware of back-up system is newest, and the firmware both when there is firmware renewal is asynchronous, and other situations are all synchronous
's）, when equipment starts next time, first start the last update system of crossing firmware, the firmware that so just can guarantee that equipment is most
New, the firmware of such as renewal is not normally functioning, then starts another system, because another system is last time normal operation mistake
, it can so complete to update, and can ensures have a system normally to start all the time during firmware renewal failure, thoroughly avoids
The situation that equipment can not start because firmware damages.
To sum up, the present invention has advantages below：
1. firmware can recover automatically, it is not necessary to manual intervention.
2. independent of network during firmware restoration.
3. system business is not influenceed during firmware restoration.
