摘要
介绍了具有多重引导加载方式的嵌入式操作系统引导程序——Bootloader的概念和作用。在基于AT91RM9200处理器的嵌入式系统开发平台上,以加载ARM-Linux操作系统内核为例,阐述了通过三种常用通信接口(串口、网口和USB接口)实现文件下载功能的软件设计方法。
This paper introduced the concept and function of embedded operating system booting programme Bootloader which had multiple downloading interface. In the AT91RM9200-based processor embedded development platform, by loading ARM-Linux operating system kernel, it expatiated on software designing methods of file-downloading function via three common communicate port（ UART ,Ethernet0 port ,USB port）.
