摘　　要：主要研究ARM和Linux嵌入式系统中Bot Loader、Linux内核及文件系统的移植方法。目标板上的微控制器是S3C2440,其内核为ARM920T,存储器有64M的SDRAM、64M的Nand Flash以及2M的Nor Flash;板上还集成了串口、网卡、鼠标、键盘、LCD、声卡等多种接口。开发环境是在VMvare虚拟机平台软件下安装的Linux操作系统,并构建交叉编译开发环境,在此基础上试验移植了Linux系统,包括U-Boot移植、配置、编译,Linux内核的移植、配置、编译,根文件系统的构建、编译。The paper mainly researches migrationes methods for BotLoader, Linux kernel and file system in embedded system of ARM and Linux. The microcontroller in target board is S3C2440, which kernel is ARM920T. The memorizer has 64M SDRAM, 64M Nand Flash and 2M Nor Flash. The board also integrates interfaces such as serial port, network card, mouse, keyboard, LCD, sound card, etc. Development environment is the Linux operating system installed under virtual machine platform software VMvare. cross-compiler development environment is constructed. On this Linux system is transplanted, which includes the transplant, config- uration, compiling of U-Boot and Linux kernel,and the construction and compiling for the root file system.

关 键 词：ARM平台 BOOTLOADER LINUX内核 根文件系统 移植
