Analysis and design based on ARM bootloader

In any embedded system application,the system software architecture can be divided into three parts: Bootloader,Kernel,and Application.Bootloader works at the bottom of the architecture stack,and facilitates kernel booting,also application development.It is very important to implement a reliable bootloader.This paper mainly focus on the general bootloader design and implement ation.Otherwise,based on the deeply understanding of the principle and the process of booting,it discovers and implements a new efficient technology for testing peripheral,which is different with the classic peripheral hardware testing method.
