Abstract

The invention is applicable to the technical field of computers, and provides a firmware upgrading method, which comprises the following steps: when a firmware upgrading request is detected, acquiringfirst firmware to be upgraded based on the firmware upgrading request; storing the first firmware into the second storage area, and updating second version information of the second storage area based on a preset version updating strategy; when the system is restarted, acquiring third edition information of the running area; obtaining target version information higher than the third version information from the first version information and the second version information, and obtaining target firmware corresponding to the target version information; and copying the target firmware to the running area, and running the target firmware. According to the method, rollback can be supported, the situation that the same firmware needs to run at different addresses can be avoided, and the firmwareupgrading efficiency is improved.

Description

technical field [0001] The present application belongs to the technical field of computers, and in particular relates to a method and device for upgrading firmware. Background technique [0002] In the prior art, the method of firmware upgrade mainly includes: 1. Temporarily store the firmware to be upgraded in the backup area, and overwrite the running area after restarting; 2. Divide into two running areas, set and run the firmware to be upgraded after burning . However, in the first method, this method does not support version rollback. If you want to roll back to the previous version, you can only "upgrade" the previous version to the target system through the upgrade process; in the second method, the firmware is required It can run in different operating areas, or when upgrading, it needs to upgrade the firmware that can run at the corresponding address according to the different addresses. That is to say, none of the existing firmware upgrade methods can support rol...
