摘　　要：很多32位SoC芯片没有在片上集成以太网控制器,需要通过外围芯片扩展以太网控制功能。嵌入式电源远程监控系统是利用RTL8019AS为32位SoC芯片SEP3203扩展网络功能实现其网络化。包括SEP3203与RTL8019AS的接口电路设计,以及结合驱动的工作机制、基本格式等,对设计在uClinux下的RTL8019AS芯片驱动程序的诸多要点进行了详细的分析探讨,给出了部分源代码,为SoC芯片的嵌入式系统的网络设备开发提供了参考。Many 32-bit SoC chips didn＇t integrate Ethernet controller on the chips ,so they need to extend the controlling functions of Ethernet through external chips. Embedded remote power control system uses RTLS019AS to extend the functions of the network for 32-bit SoC chips SEP3203 and to make them networked , including the interface circuit design of SEP3203 ＆ RTLS019AS, the working mechanism with driving,and the basic format. This paper ,which analyses and explores how to design the driver for RTL8019AS chips of uClinux in detail,and provides partial source codes, provides a reference for the development of the network devices of embedded remote power control system of SoC chips.
