嵌入式引导加载程序的可裁剪性分析

摘要

随着嵌入式系统的不断发展,系统引导加载程序(Boot Loader)变得日益重要,文中针对Cortex M3内核,从Boot Loader的原理出发,详细分析了Stellaris Boot Loader源代码及其应用要点并举出了实例,同时探讨了其可裁剪性与可移植性,初步提出了可靠并安全地移植Bootloader的方法和相关注意点.%With the development of the embedded system,the Boot Loader becomes more and more important.This article focused on the principle of the Boot Loader based on the Cortex M3 cores,and analyzed the source code of the Stellaris Boot Loader in detail.Simultaneously,it also gave out some application key points based on some real examples,and discussed on the key point of its scalability and portability order to transplant it safely.
