| 摘 要： | 嵌入式系统开发过程中的一个重要问题是如何开发Boot Loader。目前已有一些通用的Boot Loader，但如何根据特定的嵌入式系统平台，开发相应的Boot Loader，无疑是一个重点和难点。本文选用AT9IRM9200微控制器建立了一个通信接口平台，通过阐述U—Boot分析了BootLoader开发的特点和操作模式，并通过详细地分析AT91Basic Boot的源程序，具体地说明了Boot Loader需要完成的主要任务和实现方法。可见，Bot Loader是操作系统和硬件的枢纽，负责初始化硬件和引导操作系统的内核。

| Abstract: | A core problem in Embedd system's design is hocu to analysis and exploit Boot Loader. Currently, there are some common BootLoaders, but how to develop BootLoader on the basis of the specifical hardwane platform is an key toint and difficulty without question. The paper selects AT91RM9200 to make a communication interface plat-fornm. On the platform. U-Boot is illuminated to in troduce the performance character istic and operation mode. And the program of AT91 Basic Boot is analyzed in detail to illuminate the important tasks and realization method of Boothoader. From aboue, Boothoadev is the hinge of Embedd operation system and hardweme, implementing the initi lization of the hardware and leading of operation system's kernel. |
