摘　　要：开发嵌入式系统软件的关键是编写稳定可靠的设备驱动程序,VxWorks下的设备驱动程序开发难度尤其大。结合了多用于航空航天领域的嵌入式实时操作系统VxWorks的特点,详细描述VxWorks下的设备驱动程序的基本概念,以VxWorks下的板级支持包(BSP)作为比较对象,阐述设备驱动程序在整个嵌入式系统中的位置和结构,总结在系统上电后设备驱动程序的基本工作流程,最后以字符设备驱动程序为例演示驱动程序的工作流程,为VxWorks下设备驱动程序开发提供了技术途径。The key of software development of embedded system is to compile stable and reliable device driver,but the de-velopment of device driver in VxWorks is very difficult. According to characteristics of VxWorks using in field of aerospace,the basic concept of device driver in VxWorks is described,and the position and the structure of device driver in the embedded sys-tem are elaborated in this paper,which is compared with the board support package（BSP）in VxWorks. The basic workflow of device driver after power-on is summarized. Finally,the character device driver is taken as an example to demonstrate the work-flow of device driver. The research provided a technical approach for development of device driver in VxWorks.
