摘　　要：引导装载程序(bootloader)是用于初始化系统硬件,完成嵌入式操作系统装载、引导和运行的固件程序。U-Boot是一种当前比较流行、功能强大的bootloader,能够支持多种CPU体系结构,具有下载、引导程序的功能。本文从实际出发,根据移植的最小要求准则和系统的硬件资源,以U-Boot源码中自带的B2例子为基础,成功地将U-Boot移植到了以三星S3C44B0X为微处理器的嵌入式系统板上,并最终实现了引导嵌入式μClinux操作系统内核启动的功能。测试结果证明该方法行之有效,并具有一定的通用性和灵活性。Boot loader is a firmware program which can help initialize hardware system, and load embedded operating system executable codes. U-Boot is a popular, powerful Boot Loader, can support a variety of CPU architecture. This design successfully ports U-Boot to Samsung S3CA4BOX, which comes from the B2 demo of U-Boot source codes follows the standard of minimum requirement of porting based on hardware resources. It eventually achieves the function of booting Embedded μClinux operating system kernel start. Test results show that the method is effective, and has a certain generality and flexibility.
