MPC 8260 has been widely used in communication and network areas because of its powerful ability of communication processing and support to many protocols. Taken MPC8260 as an example, the hardware design of the fast Ethemet in embedded system is discussed and the architecture of network system in VxWorks is analyzed. Then the driver programming of Ethemet based on VxWorks is described in detail. It has a reference value for other network device driver developers.
