| 摘 要： | 在嵌入式系统开发中,正确引导开发板是嵌入式软件开发的关键所在.引导加载程序Bootloader是严重依赖于硬件而实现的,建立一个通用的Bootloader几乎是不可能的.紧密结合PXA270嵌入式系统的主要硬件构成,对Bootloadcr的启动过程和存储映射进行了研究.针对本嵌入式系统的基本硬件设计,以u-boot-1.1.4为例探讨了Boofloader的移植方法和要点,并最终实现了嵌入式开发板的引导.

| Abstract: | In the embedded system development, it is very important to guild the development board correctly in the embedded software development. The realization of Bootloader is quite dependent on hardware and it is impossible to establish a common Bootloader.In close connection with the main hardware composing of embedded system based on PXA270, the startup process and the memory map of Bootloader are mainly studied. Finally, according to the basic hardware design of embedded system, u-boot-1.1.4 is taken for example to discuss the method and point of Bootloader porting, and the guide of embedded development board is eventually realized. |
