5. Ethernet 使用¶
5.1. dts 配置¶
5.1.1. 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";
};
5.1.2. 板级的配置¶
kernel-5.10/arch/arm64/boot/dts/rockchip/rk3588s-firefly-aio-3588sg.dtsi
/* gmac1 */
&gmac1{
snps,reset-gpio = <&gpio1 RK_PA1 GPIO_ACTIVE_LOW>;
tx_delay = <0x37>;
status = "okay";
};
5.1.3. 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 02:df:a5:01:03:cf Driver rk_gmac-dwmac UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 TX bytes:0 Interrupt:80
5.1.4. 连通性测试¶
eth0
