摘　　要：ARM广泛应用于嵌入式处理领域,AT91RM9200是基于ARM920T构建的处理器芯片,该芯片支持片内引导和片外引导2种方式,通过片内引导完成U-Boot在目标平台的加载和运行。以U-Boot为基础,完成了VxWorks在目标平台上的移植和运行。通过U-Boot和BootRom两种方式分别实现了嵌入式软件系统平台的构建,并介绍了实现方法和步骤。ARM is widely used in the field of embedded processing. AT91RM9200 is a processor chip based on ARM920T. Both internal boot and external boot modes are supported by AT91RM9200. Internal boot performs the loading and running of U-boot on the target platform. On the basis of U-Boot, the porting of VxWorks to the target platform is completed. The embedded software system platform is constructed with U-Boot and BootRom modes respectively, and the methods and procedures are introduced.
