Development and Realization of END Network Driver Design in VxWorks Systems
Uav Special · Computer Measurement & Control · 2009
With the advantage of extensive application and convenience of network resources and its resources sharing,network technology has found more extensive application in various fields,and Embedded System is no exception.However,the number of network cards supported by the Embedded Operating System is limited,which greatly limits the real-time operation system Vxworks' utilization of network resources,so the design of Network Driver in Vxworks systems comes to be a hotspot and difficulty.This paper gives a detailed representation of the development process of End Network Driver in MUX environment and a detailed research into and discussion of the configuration and function of Board Support Package(BSP) and MUX's function in the End Network Driver in Vxworks environment.Combined with network card RTL8139D's usage in the design of the driver in real-time operating system VxWorks,this papers lays out the basic framework and development process of END driver,which may have a reference value for other network device driver developers.
