Abstract

The present disclosure provides a method for over-the-air update of compressed firmware, including the following steps: step S1: dividing firmware of an electronic device into a plurality of partitions at a firmware compilation stage, where each partition includes one or more functional modules, and each partition has substantially a same size after being compressed; step S2: compressing the firmware of the electronic device on a partition basis, recording relevant information of a compressed partition during the compression, and storing relevant information of all compressed partitions in a header of compressed firmware of the electronic device in a form of a data loading table; step S3: generating an update file table, obtaining differential data of the data loading table and differential data of each partition, and sequentially assembling to obtain a differential update file; and step S4: updating, by the electronic device after acquiring the differential update file for new compressed firmware and old compressed firmware, the data loading table, and then updating the firmware on a compressed partition basis. According to the present disclosure, a best differential effect is achieved, and a small storage space is occupied by power failure protection in an update process.
