3. Ethernet 使用
3.1. dts 配置
3.1.1. 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";
};
3.1.2. 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";
};
3.2. 如何使用双以太网
Android 双以太网口分内网和外网。
注意：eth1副网口为usb2.0拓展网口因此最高速率为百兆
| 硬件设备名 | 驱动 | Android 系统设备名 | 主副关系 | 网速 |
|---|---|---|---|---|
| eth0 | rk_gmac | Ethernet | 主网口，用于外网 | 千兆网 |
| eth1 | r8152 | Ethernet 2 | 副网口，用于内网 | 百兆网 |
3.2.1. 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 eth0eth0 Link encap:Ethernet HWaddr 52:22:4b:e4:f8:3c Driver rk_gmac-dwmacinet addr:168.168.104.210 Bcast:168.168.255.255 Mask:255.255.0.0inet6 addr: 240e:3b1:f175:9df0:ea6d:9993:33e6:202d/64 Scope: Globalinet6 addr: 240e:3b1:f175:9df0:e0e8:b021:fc7a:dafc/64 Scope: Globalinet6 addr: fe80::9cd8:e64d:b9c2:6f4/64 Scope: LinkUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:229 errors:0 dropped:0 overruns:0 frame:0TX packets:62 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:40526 TX bytes:6698Interrupt:70ifconfig eth1eth1 Link encap:Ethernet HWaddr e2:76:ef:f2:13:4f Driver r8152inet addr:168.168.105.2 Bcast:168.168.255.255 Mask:255.255.0.0inet6 addr: 240e:3b1:f175:9df0:7355:7ec7:fed3:ecab/64 Scope: Globalinet6 addr: 240e:3b1:f175:9df0:2e23:792d:f04a:2975/64 Scope: Globalinet6 addr: fe80::564f:1114:e491:4bbd/64 Scope: LinkUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:124 errors:0 dropped:1 overruns:0 frame:0TX packets:18 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:12387 TX bytes:2072
