摘　　要：大多数的嵌入式Linux引导加载程序(Bootloader)都是基于开发应用的引导代码,做成产品需要裁剪。为了减少Bootloader的代码容量,加快系统启动速度,以S3C2440开发板硬件特点和嵌入式Linux启动需求的两个方面为主进行了Bootloader的分析与设计。并提出了一种设计Bootloader的一般方法,该方法简单易行,编写的Bootloader大小不足4k。Most embedded Linux Bootloaders are based on the development and application, the codes need to cut at the last product release. In order to reduce the capacity about Bootloader code and quicken the startup speed, the Bootloader analysis and design based on the S3C2440 board hardware features and embedded Linux needs for reboot. A simple method to design Bootloader was presented and codes written using this method less than 4k.
