Single board software restoring method and single board thereof

Abstract

The invention discloses a single board software repairing method and a single board; the method in the invention includes that if the basic BIOS jumps to the extensible BIOS when the basic BIOS operates over, the extensible BIOS operates over to detect the integrity of the single board APP; if the single board APP is damaged; the extensible BIOS starts the upgrading function to repair the damagedsingle board APP; if the basic BIOS jumps to the single board APP, the single board APP operates over to detect the integrity of the extensible BIOS; if the extensible BIOS is damaged, the single board APP starts the upgrading function to repair the damaged extensible BIOS. When the single board software repairing method and the single board are adopted, the single board software can be repaired automatically when the single board software is damaged; the maintenance is convenient; the service interruption time is reduced and the maintenance cost is saved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for repairing single board software and a single board. Background technique [0002] In the field of access network, the physical form of product equipment is mostly frame-slot type, and the main control board and service single board are inserted into the slots of the frame, and communicate through the backplane of the frame. Single-board software usually includes basic BIOS (Basic Input Output System), extended BIOS, and single-board APP (Application Program). Basic BIOS, extended BIOS and single-board APP are all stored in the single board without power failure. Lost media (such as FLASH). The basic BIOS mainly performs the initialization of some basic hardware (CPU, memory) and the loading function of the extended BIOS. After the basic BIOS runs, it jumps to the extended BIOS operation. The extended BIOS mainly implements some lower-level hardware (networ...

AI Technical Summary

Problems solved by technology

[0006] During the research and practice of the prior art, the inventor found at least the following problems in the first prior art: the distribution of equipment sites in the field of access network is very wide, and the maintenance personnel need to go to the site to solve the problem and the cost is very high; For a single board with integrated BIOS and extended BIOS, the single board needs to be mailed back to the manufacturer for repair, which is costly and takes a long time. If there is no spare board for temporary use, it will cause service interruption; maintenance personnel must obtain the correct single board software and be familiar with the The loading process, which requires certain technical and skill requirements for maintenance personnel, is prone to errors and the reliability is not high enough

[0008] During the research and practice of the prior art, the inventor found at least the following problems in the second prior art: since the number of single boards is generally large, enlarging the storage medium of the single board will greatly increase the hardware cost of the single board
