摘要
在ARM7处理器NUC710ADN的第一个网口的基础上,利用网口驱动芯片DM9000AEP扩充了第二个网口,使系统实现双网口通信。给出了硬件设计电路,对DM9000AEP的驱动程序在μClinux下的移植过程进行了描述,测试结果表明双网口都能正常可靠的工作,达到了ARM7处理器进行双网通信的功能要求。
Based on the first ARM7 processor NUC710ADN port,using the network interface driver chip DM9000AEP expanded second network interfaces,allowing the system to achieve the dual network communication.Then the hardware design circuit, the DM90OOAEP driver under μClinux transplant process is described in this paper.Test results show that the dual network can be normal and reliable work,achieves the ARM7 processor for network communication function.
