Abstract

The embodiment of the invention provides a firmware upgrading method and device which are applied to electronic equipment, original firmware to be upgraded is arranged in the electronic equipment, and the method comprises the steps of obtaining a description file of the original firmware to serve as a first description file; wherein the description file is a preset file used for recording the content attribute of each file in the firmware to which the description file belongs; obtaining difference information determined by utilizing the first description file and a second description file; wherein the second description file is a description file of target firmware to be upgraded from the original firmware, and the difference information is used for indicating a target file identifier of a file with content difference between the original firmware and the target firmware and a target upgrading operation; and executing a target upgrading operation by utilizing a file indicated by the target file identifier so as to upgrade the original firmware. Through the scheme, the firmware upgrading efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data updating, in particular to a firmware upgrading method and device. Background technique [0002] Firmware is a general term for software required to maintain normal operation of electronic devices, basic components in electronic devices, and pre-installed applications. A firmware includes at least one file. In order to improve the operating performance of the electronic device, when the device manufacturer releases new firmware, it is necessary to upgrade the firmware running in the electronic device to the new firmware. [0003] Existing firmware upgrades generally adopt a differential upgrade method, that is, the device manufacturer releases new firmware in the form of an upgrade package in advance, and the upgrade package released by the device manufacturer contains all files of the new firmware. When the electronic device needs to upgrade the firmware, the upgrade server needs to perform a binar...
