摘要
引导程序是嵌入式系统的重要组成部分,主要完成系统底层硬件的初始化、内核引导等功能。基于ARM9 S3C2440开发平台,分析U-Boot工作机制,给出U-Boot移植和添加命令的步骤以及关键代码。
As one of important parts of the embedded system, the bootloader performs full system＇s underlying hardware initial- ization, and loads the kernel. Based on ARM9 S3C2440, U-Boot working mechanism was analyzed, the key code and steps for trans- plantation and command of U-Boot were proposed.
