METHOD AND DEVICE FOR UPGRADING FIRMWARE

摘要

The present disclosure discloses a method and a device for upgrading firmware, so as to improve the security during upgrading firmware. The method comprises: when it is determined that firmware of a first chip needs to be upgraded, identifying (S101) a first partition of a flash memory in a second chip, for downloading firmware of the second chip; downloading (S102) new firmware of the first chip to the first partition; and copying (S103) the new firmware of the first chip from the first partition to an effective position in the first chip. The technical solutions of the present disclosure may avoid conflict caused by upgrading firmware of a plurality of chips simultaneously, so as to improve the security of upgrading firmware, and avoid additional control logic during the upgrading and save resources of the intelligent device.
