Firmware differential upgrade package manufacturing method and device and readable storage medium

Abstract

The invention provides a firmware differential upgrade package manufacturing method and device and a readable storage medium. The firmware differential upgrade package manufacturing method comprises the steps of obtaining a target file of a current version of target firmware and a target file of an upgrade version; wherein the source code corresponding to the target file of the current version andthe source code corresponding to the target file of the upgraded version are obtained in an address-independent compiling mode, and the connection sequence of the target file of the current version and the target file of the upgraded version is consistent; determining a difference target file with difference in the target file of the current version and the target file of the upgraded version; carrying out difference analysis on the difference target file to respectively obtain difference information of the current version and the upgraded version; and generating a differential upgrade package according to the difference information. According to the method, the applicability of the differential upgrade package is improved.

Description

Technical field [0001] This application relates to the technical field of the Internet of Things, and in particular to a method and device for making a firmware differential upgrade package, and a readable storage medium. Background technique [0002] With the rapid development of Internet of Things technology, embedded Internet devices have been widely used in various fields. In the Internet of Everything, the scale of device terminals is huge, and the industry will have a demand for online upgrades of IoT devices due to functional requirements and security requirements. The full upgrade of embedded devices will transmit a large amount of data, which may not be applicable in some network environments. Traditional differential algorithms have certain requirements for processor capabilities and are not suitable for low-end applications. [0003] In the prior art, the upgrade file is divided into blocks, the differences of the corresponding blocks of the new and old upgrade files a...

AI Technical Summary

Problems solved by technology

Although the algorithm provides two calculation methods, forward and reverse, and takes a minimum upgrade package method, when multiple program blocks are modified in the old and new programs or the size of the modified program segment changes, the calculated difference files are compared. Large, not optimally provide differential upgrade packages

[0004] Therefore, the way of generating the differential upgrade package of the firmware of the existing embedded device is poor in applicability
