摘　　要：Bootloader是嵌入式系统软件开发的第一个环节,用于初始化目标板硬件,给嵌入式操作系统提供板上硬件资源信息,并进一步装载、引导嵌入式系统的固件,其性能直接影响系统的稳定性。为了引导嵌入式操作系统,根据S3C44B0开发板上特定的硬件信息,在不改变Bootloader架构的前提下,对与硬件相关的代码,特别是FLASH芯片Intel 28F320C3B代码进行了添加修改,将U-boot成功地移植到了开发板上,并在基于μCLinux的智能机器人避障系统中使用良好。Bootloader is the first phase in developing embedded system software, which is used to initialize the hardware of target board and provides embedded operation system with hardware source information in board. It further bootloads embedded system firmware and the quality of performance directly affects the stability of the system. In order to guide embedded operation system,according to the special hardware information of S3C44B0 development board, on the premise that the bootloader structure is not changed and by appending and modifying code related to hardware in particular Intel 28F320C3B FLASH chip, U - boot is ported successfully to development board and well applied to intelligent robot obstacle avoidance system based on μClinux.
