控制Uboot进入下载操作模式的方法及系统

Abstract

Provided is a method and a system for controlling U boot to enter a download operation mode. The method comprises that a Booter and a first operation system are established, the first operation system comprises a first kernel, a first file system, and a user App program; a second operation system is established, the second operation system comprises a second kernel, a second file system, and a Loader, and the Loader can be loaded as an App program by the second operation system; after a computer is started, the Booter judges whether upgrade requirements exist or not, and if the upgrade requirements exist, the second operation system is started to conduct upgrade operation through loading the Loader; and if the upgrade requirements do not exist, the first operation system is started. According to the method and the system for controlling the U boot to enter the download operation mode, related drive realized in the Loader is avoided, and thus development efficiency of software systems of embedded products is improved.
一种控制Uboot进入下载操作模式的方法及系统,该方法包括:构建一Booter以及一第一操作系统,该第一操作系统包括第一内核、第一文件系统以及用户App程序;构建一第二操作系统,其包括第二内核、第二文件系统以及一Loader,该第二内核能够将该Loader作为一个App程序进行加载;在开机后,该Booter判断是否有升级要求,如果有,启动该第二操作系统,通过加载该Loader进行升级操作;如果没有,启动该第一操作系统。本发明可以省去在Loader中实现相关驱动的必要,从而提高嵌入式产品的软件系统的开发效率。
