Embodiment Construction

[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] Generally, the board software upgrade is due to the addition of new requirements or problems in the version. In both cases, the software is changed on the basis of the original version. Generally, the code changes will not be large. The previous software changes are changes to specific software modules, so some modules can be dynamically upgraded. This processing means that only the modified modules are upgraded during the software upgrade process, and the unmodified modules remain unchanged. Obviously, this processing will greatly increase the download speed.

Abstract

The present invention provides a board software upgrade method, including the following steps: the background module transmits an upgrade request to the foreground module; the load sub-module of the foreground module receives the upgrade request, reads the present state information from the parameter management sub-module of the foreground module, and transmits the present state information to the background module; the background module compares the present state information with the state information in the upgrade information, and upgrades the foreground module according to the compared result, thereby improving the load velocity in the board software on-line upgrade process.

Description

technical field [0001] The invention relates to a single-board software version upgrade technology in an embedded system, in particular to a method for more effectively improving the version download speed in the case of a single-chip software version upgrade and a single-board system for realizing front-end and back-end verification upgrades. Background technique [0002] In embedded system equipment, due to changes in requirements and defects in the software itself, the software is often upgraded. The method adopted in the early stage is to take out the chip on the single board in the system equipment, burn it through the burner and insert it back into the single board again. The disadvantage of this method is that the maintenance cost is high, the efficiency is low, and the single board service needs to be interrupted. [0003] At present, in order to improve efficiency and reduce maintenance costs, online upgrades have been realized, that is, each single board of the em...
