摘要
Bootloader是嵌入式系统开发中的第一个环节,它将系统的软硬件紧密联系在一起,其性能的好坏对系统的稳定性有着至关重要的影响。U-Boot功能强大,可移植性好,适合作为S3C44B0开发板上引导μCLinux的BootLoader。重点介绍了U-Boot的运行机理,结合代码详细分析了U-Boot的移植方法,并成功地将U-Boot移植到开发板上。
Bootloader is the first step in developing embedded system, which ties tightly software with hardware. Its performance has a crucial effect on the stability of the embedded system.Because of U-Boot＇ s strong function and easy porting, it is very fit to become a Bootloader for μCLinux on S3Cd4BO.This paper stresses the running mechanism of U-Boot,then analyzes the porting measure of U-Boot in detail combined with the code, and has ported U-Boot to the board successfully.
