Upgrade method of embedded operating system

Abstract

The invention relates to a method for upgrading an embedded operating system. The method comprises the following steps of: (1) unpacking a start program for upgrading, a system program, operation configuration information and upgrade structure information into an upgrade file and storing; (2) detecting whether the upgrade file exists or not when the start program is operated, if not, normally starting the system program and implementing the step (6), and if so, implementing the step (3); (3) acquiring the upgrade structure information in the upgrade file; (4) sequentially upgrading each module to be upgraded according to the upgrade structure information till the end of upgrade of all the modules; (5) finishing the upgrade and operating the system program after the upgrade; and (6) reading the operation configuration information during the operation of the system program, and operating in different states according to the configuration information. According to the method provided by the invention, the upgrade efficiency of the embedded operating system can be effectively improved, and the problem of systematic chaos caused by mistakes when the operation is upgraded through an external communication port in the past can be simultaneously avoided effectively.

Description

technical field [0001] The invention relates to a system upgrading method, in particular to an embedded system upgrading method. Background technique [0002] At present, there are generally two ways to upgrade software. One is that during the development process, the developer uses the debugging serial port to specify the content of the file to be updated by command, and burns the corresponding file to the target board in turn. This operation The process is relatively cumbersome, and requires a certain understanding of commands and is dependent on data connections. The other is the update and maintenance after the software is released. If there are multiple applications that need to be upgraded, it is necessary to avoid confusion caused by too many files. The method is used to detect and verify, which eventually leads to the failure of the upgrade. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present inventi...
