摘　　要：VxWorks操作系统在嵌入式系统中的应用越来越广泛。但是当PCI总线出现故障时,VxWorks操作系统无法正常启动,并且人工检测故障的方法效率低下。介绍了一种VxWorks下对PCI总线设备的故障诊断方法,重点描述了VxWorks对PCI总线初始化的配置过程以及故障诊断的思路和流程。The application of VxWorks OS in Embedded System is being used widely.But when the PCI Bus breakdown,the VxWorks OS can not start up in normal mode,the efficiency of fault detection with manual Method remains very weak.This paper mainly introduces a method of failure diagnosis scheme of PCI Bus under VxWorks OS,particular describes the ideas and flow chart under VxWorks for the initialization of PCI bus configuration process and failure diagnosis.
