Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0039] Generally speaking, when the hardware platform of the product is fixed, the possibility of modifying the bootloader and operating system is very small, and the improvement in the later period is more about the fine-tuning of the application program or driver module, so it is better to upgrade the application program and driver module independently. solution.

[0040] This embodiment provides a method for online upgrading of embedded firmware, such as figure 1 As shown, it involves a remote client and an embedded terminal, both of which complete the online upgrade of firmware through a communication protocol recognized by both parties. This method adopts the embedded linux operating system to realize the update of the main application and the driver at the applica...

Abstract

The invention discloses an embedded firmware online upgrade method. The method comprises the steps that a remote client issues an update file to an embedded terminal through an upgrade port; an upgrade service program of the embedded terminal runs at the background, the upgrade port is monitored, and the update file is transmitted abiding by a protocol accepted by both parties once a demand is made; after the embedded terminal judges that the update file is transmitted successfully and is intact, the update file is saved into an update directory, and then a system is rebooted; after the embedded terminal is started to enter the system, a start detection script of the embedded terminal judges whether the update file is under the update directory, and if yes, the update file is copied to a corresponding application program directory and a driving directory; and after copying is completed, the original file under the update directory is deleted, a driving module, a main application program and the upgrade service program are loaded, and upgrade is completed. Through the method, upgrade of the application program and the driving module can be realized quickly and effectively.

Description

technical field [0001] The invention relates to the field of computer embedded software, in particular to an online upgrade method for embedded firmware. Background technique [0002] For traditional embedded terminal equipment, due to the limitation of resources and environmental conditions, the software code needs to be solidified during the production stage, and it cannot be modified online after the equipment leaves the factory. Once there is a demand for upgrading, either the equipment must be returned to the factory for maintenance, or the equipment must be disassembled on site to replace component boards or program memory chips. [0003] In order to meet the continuously changing needs of customers and prolong the life cycle of products, it is necessary to continuously improve the functions of embedded terminal equipment, and the online upgrade capability is very important. The common upgrade method is to upgrade the entire equipment system. In the real environment, ...
