U-Boot在S3C44B0上的移植方法

Porting Method of U-Boot in S3C44B0 Board

Bootloader(引导加载程序)是嵌入式系统CPU加电后第一个开始运行的代码.在内核映像执行之前完成相关的底层硬件的初始化,建立内存空间的映射图等重要工作,然后为内核提供引导参数,启动内核.DasU Boot(UniversalBootloader),是一个功能十分强大的Bootloader,本文深入研究了U Boot的工作机理,详细分析了U Boot在基于三星公司S3C44B0处理器的嵌入式系统板上的移植方法、过程与移植要点.

Bootloader (Boot Load Program) is the first running program after powering up an Embedded Board. Bootloader performs the specific hardware initialization and sets up the memory space map and other tasks before the Embedded Operating System kernel image executes. After that, it provides the boot parameters for the kernel and starts up the kernel. Das U-Boot(Universal Bootloader) is a powerful Bootloader. This paper particularly analyses the porting method, process and porting main feature of U-Boot in an Embedded System board based on the SAMSUNG S3C44B0 CPU.
