4. Ethernet 使用

4.1. dts 配置​

4.1.1. 公共的配置​

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

&gmac1 {                                                                                                                                                                
    /* Use rgmii-rxid mode to disable rx delay inside Soc */
    phy-mode = "rgmii-rxid";
    clock_in_out = "output";

    snps,reset-gpio = <&gpio3 RK_PB7 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 = <&gmac1_miim
            &gmac1_tx_bus2
            &gmac1_rx_bus2
            &gmac1_rgmii_clk
            &gmac1_rgmii_bus>;

    tx_delay = <0x42>;
    //rx_delay = <0x4f>;

    phy-handle = <&rgmii_phy1>;
    status = "disbaled";
&#125;;

4.1.2. 板级的配置​

kernel-5.10/arch/arm64/boot/dts/rockchip/roc-rk3588s-pc.dtsi

/* gmac1 */
&gmac1{
 	snps,reset-gpio = <&gpio0 RK_PD3 GPIO_ACTIVE_LOW>;
	tx_delay = <0x43>;
	status = "okay";
&#125;;

4.1.3. 查看IP地址​

  • 双以太网口接入网络，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 52:22:4b:e4:f8:3c  Driver rk_gmac-dwmac
          inet addr:168.168.104.210  Bcast:168.168.255.255  Mask:255.255.0.0
          inet6 addr: 240e:3b1:f175:9df0:ea6d:9993:33e6:202d/64 Scope: Global
          inet6 addr: 240e:3b1:f175:9df0:e0e8:b021:fc7a:dafc/64 Scope: Global
          inet6 addr: fe80::9cd8:e64d:b9c2:6f4/64 Scope: Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:229 errors:0 dropped:0 overruns:0 frame:0
          TX packets:62 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:40526 TX bytes:6698
          Interrupt:70

4.1.4. 连通性测试​
