Abstract

The invention relates to a method and device for updating a firmware. The method and the device are used for improving the safety in the firmware updating process. The method comprises the following steps that when the firmware of a first chip needs to be updated, a first partition, used for downloading the firmware of a second chip, in a flash memory of the second chip is identified; the new firmware of the first chip is downloaded into the first region; the new firmware of the first chip is copied to an effective region in the first chip from the first partition. The technical scheme disclosed by the invention has the advantages that the conflict occurring during the simultaneous updating on the firmware of a plurality of chips can be avoided, the safety during the updating on the firmware of the chips is improved, the adoption of additional control logics in the updating process is avoided, and resources of intelligent equipment are saved.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular to a method and device for upgrading firmware. Background technique [0002] The firmware upgrade refers to refreshing the embedded firmware of the embedded Micro Control Unit (MCU), so as to improve the functions of the smart device and enhance the stability of the smart device. In more complex smart devices, there will be multiple MCU or MCU-like chips and non-MCU chips that need to upgrade the firmware. Non-MCU chips such as Wireless Fidelity (WIFI) chips, Bluetooth chips, etc. . When upgrading multiple firmwares, if the multiple firmwares are individually upgraded, resources are likely to be wasted. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the embodiments of the present disclosure provide a method and device for upgrading firmware, so as to improve security during the firmware upgrading process. ...
