摘要

具有复杂的嵌入式微处理器内部资源和丰富的外围设备的嵌入式系统，如果没有操作系统的管理，就无法高效地工作。如何基于特定的硬件平台开发Boot Loader无疑是一个重点和难点。介绍了具有多个通信端口的嵌入式操作系统启动程序boot Loader的概念和功能。在ARM & DSP双核嵌入式微处理器系统开发平台上，通过加载Linux操作系统内核，阐述了通过UART、Ethernet0、USB三种常用通信接口下载文件的软件设计方法。

Design of Boot Loader with Multiple Communication Port

An embedded system with complex embedded microprocessor inner resources and plentiful peripheral devices cannot work efficiently without the management of operating system. How to develop Boot Loader on the basis of the specific hardware platform is a key point and difficulty without question. The concept and function of embedded operating system booting program-Boot Loader which has multiple communication ports is introduced. In the ARM & DSP dual-core embedded microprocessor system development platform, by loading Linux operating system kernel, the authors expatiate on software designing methods of file downloading via three common communication interfaces (UART, Ethernet0, USB port).
