3. Ethernet 使用

目前 ROC-RK3588-PC 只支持 1 个 千兆网口（Ethernet0） ，但通过 164 Pin 接口可以扩展第 2 个千兆网口（Ethernet1）。

3.1.1. 公共的配置​

kernel-5.10/arch/arm64/boot/dts/rockchip/rk3588-diff.dtsi

&gmac0 {
    /* Use rgmii-rxid mode to disable rx delay inside Soc */
    phy-mode = "rgmii-rxid";
    clock_in_out = "output";

    snps,reset-gpio = <&gpio3 RK_PC7 GPIO_ACTIVE_LOW>;
    snps,reset-active-low;
    /* Reset time is 20ms, 100ms for rtl8211f */
    snps,reset-delays-us = <0 20000 100000>;

    pinctrl-names = "default";
    pinctrl-0 = <&gmac0_miim
            &gmac0_tx_bus2

3.1.2. 板级的配置​

3.2. 如何使用以太网​

3.2.1. 查看IP地址​

  • 以太网口接入网络，可以通过调试串口或者adb来查看IP地址，比如

    ifconfig eth0
    eth0  Link encap:Ethernet  HWaddr 36:0a:d2:60:c9:05  Driver rk_gmac-dwmac
          inet addr:168.168.101.68  Bcast:168.168.255.255  Mask:255.255.0.0 
          inet6 addr: fe80::3290:2dc:3624:1dec/64 Scope: Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:15804 errors:0 dropped:1 overruns:0 frame:0 
          TX packets:68 errors:0 dropped:0 overruns:0 carrier:0 
          collisions:0 txqueuelen:1000 
          RX bytes:1811566 TX bytes:6748 
          Interrupt:75

3.2.2. 连通性测试​
