zynq-7000 7Z020 双网卡调试

zynq-7000 7Z020 双网卡调试

1. 网卡芯片
   采用两片RTL8201F MII模式
   
   注意：图中R920需要去掉。

2. 设备树添加
   &gem0 {
   compatible = “cdns,zynq-gem”;
   status = “okay”;
   phy-mode = “mii”;
   clock-frequency = <25000000>;
   xlnx,ptp-enet-clock = <0x69f6bcb>;
   phy-handle = <&phy0>;
   local-mac-address = [00 0a 35 11 22 34];
   mdio
   {
   phy0:phy@1{
   compatible = “ethernet-phy-id001c.c816”;
   device_type =“etherne-phy”;
   reg = <0x01>;
   };

   phy1:phy@2{
       compatible = "ethernet-phy-id001c.c816";
       device_type ="etherne-phy";
       reg = <0x02>;
   };
   

   };
   };

&gem1 {
compatible = “cdns,zynq-gem”;
status = “okay”;
phy-mode = “mii”;
xlnx,ptp-enet-clock = <0x69f6bcb>;
phy-handle = <&phy1>;
local-mac-address = [00 0a 35 11 22 35];

};

4. 打印结果
   

5. 系统启动后ifconfig -a查看状态
