U-Boot在S3C2440上移植和设置

BootLoader是嵌入式系统开发的重要环节,是操作系统和硬件平台联系的桥梁,对嵌入式系统的后继开发十分重要.简介了BootLoader U-Boot目录结构、工作流程及其移植的思路和引导内核的方法；给出了移植uboot-2010-03到ARM微处理器S3C2440上,所需操作环境的搭建、具体代码的修改、具体参数的设置、所需的操作命令及常见错误的处理方法等要点.最后将编译生成了U-Boot.bin文件下载到ARM微处理器S3C2440上,经过测试U-Boot可以达到设计的功能要求并能够稳定的运行而且通过对其正确的配置成功的引导了内核.

Porting and Setting Method of U-Boot on S3C2440 Platform

This paper introduces directory structure,workflow,a porting thought and a booting kernel method of bootloader U-Boot,and gives those points of transplant uboot-2010-03 to S3C2440 which include particularly recommended the environment established,the specific changes to the file,the specific settings to parameter,the demand of operation command and the familiar faults.Finally porting U-Boot.bin to the platform,attain request of project,run steadily and boot the kernel successfully through the proper configuration of the uboot.
