基于嵌入式系统的远程在线升级双BOOT设计

Design Of Dual-BOOT that can be upgraded on-line remotely Based on Embedded System

为了满足版本的正确稳定升级,满足嵌入式系统高可靠性的要求,要求在系统存储多个BOOT引导程序并能实现BOOT版本的在线升级。本文论述了一种基于嵌入式系统的支持远程在线升级的双BOOT设计和实现方式,目前这种双BOOT设计已在诸多3G基站的各通讯控制模块中得到广泛应用。

In order to upgrade version correctly and steadily and meet the requirement of high reliability of the embedded system, it is required that a number of boot programs should be stored in system and boot on-line upgrade should be realized. This paper discusses a principle and realization of dual boot based on embedded system supporting remote on-line upgrade and this dual boot design has been used broadly in most communication and control module in 3G Base Station.
