摘要
从ARM7处理器SEP3203在无线通信平台中的应用实例出发,对无线通信平台的硬件结构和软件流程进行了分析;说明了其板级支持包(BSP)的基本构成;探讨并实现了SEP3203的启动代码,使之完成了从系统上电到主函数开始运行之间的底层相关任务,为主函数的运行创造了运行环境;对启动代码中的难点进行了分析,着重阐述了其启动代码的实现。
Based on the Wireless Transmission Unit which is an application of a ARM7 processor called SEP3203. Analyze the frame of the hardware and the flow of software in the application.Account for the frame of BSP.Realize the startup code based on SEP3203. The startup code will be executed to prepare for main function. Analyze the difficulty in the startup code . The method to write the startup code is described specially.
