摘　　要：AT91RM9200是基于ARM920T处理器构建的具有丰富的外设、低功耗、低成本、高性能等特点的单芯片系统,可广泛应用于工业、自动控制、通信等领域。在基于AT91RM9200平台的嵌入式系统设计过程中,遇到的第一个难点是Boot loader(启动引导)设计。将分析U-boot的架构,并描述其在软件设计中一些需要注意的重点。AT91RM9200 is a system-on-chip constructed on the basis of ARM920T ARM Thumb processor. It incorporates a rich set of application peripherals and could provide a solution for a wide range of applications, including industry, autocontrol, and communications that pursue maximum functionality at minimum power consumption and lowest cost. In the design process of embedded system,the first nodus is the design of boot loader. This article analyzes the framework of U-boot, describes some focuses on software design.
