| 摘 要： | Bootloader是嵌入式系统开发的一个重要环节,它把操作系统和硬件平台衔接起来,对嵌入式系统后继软件开发十分重要.U-Boot是一个功能十分强大的Bootloader开发软件.尽管U-Boot支持大部分主流体系结构和操作系统,但是要将其运行在一个全新的硬件开发板上还是需要进行大量的修正.对U-Boot的结构及运行的流程进行了详细的分析,并根据以PXA270为核心的XSBase270实验平台的具体硬件配置情况,将U-Boot1.3.0-rc2移植到此实验平台.最后对实验结果进行了测试,目前,U-Boot可以成功从FLASH启动,并最终实现了引导Linux操作系统内核启动的功能.

| Abstract: | Bootloader is very important in embedded system development.It links OS and hardware platform.It is very important for later software development.U-Boot is a powerful software to develop a bootloader.Although U-Boot supports most of the architectures and operating systems,to run it on a brand new development board,there is still lots of work to be done.Based on the analysis to the structure of U-Boot and its run flow in this paper,the U-Boot1.3.0-rc2 has been ported to the platform XSBase270 which use PXA27... |
