The Upgrade Method of Embedded Operating System

Abstract

The invention relates to a method for upgrading an embedded operating system. The steps are as follows: (1) packaging the startup program for upgrading, system program, operation configuration information and upgrade structure information into an upgrade file and storing it; (2) when running the startup program Check whether there is an upgrade file, if not, start the system program normally, and execute step (6); if there is, execute step (3); (3) Obtain the upgrade structure information in the upgrade file; (4) Upgrade each Each module needs to be upgraded until all modules are upgraded: (5) End the upgrade and run the upgraded system program; (6) Read the running configuration information when the system program is running, and run in different states according to the configuration information. The method of the invention can effectively improve the upgrading efficiency of the embedded operating system, and at the same time, can effectively avoid the problem of system confusion caused by errors during upgrading through an external communication port in the past.

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...
