4. Ethernet 使用¶
4.1. dts 配置¶
4.1.1. 公共的配置¶
kernel/arch/arm64/boot/dts/rockchip/rk3568-firefly-port.dtsi
&gmac0 {
phy-mode = "rgmii";
clock_in_out = "input";zzz
snps,reset-gpio = <&gpio2 RK_PD3 GPIO_ACTIVE_LOW>;
snps,reset-active-low;
/* Reset time is 20ms, 100ms for rtl8211f */
snps,reset-delays-us = <0 20000 100000>;
assigned-clocks = <&cru SCLK_GMAC0_RX_TX>, <&cru SCLK_GMAC0>;
assigned-clock-parents = <&cru SCLK_GMAC0_RGMII_SPEED>, <&cru CLK_MAC0_2TOP>;
pinctrl-names = "default";
pinctrl-0 = <&gmac0_miim
&gmac0_tx_bus2
&gmac0_rx_bus2
&gmac0_rgmii_clk
&gmac0_rgmii_bus>;
tx_delay = <0x3c>;
rx_delay = <0x2f>;
phy-handle = <&rgmii_phy0>;
status = "disabled";
};
&gmac1 {
phy-mode = "rgmii";
clock_in_out = "input";
snps,reset-gpio = <&gpio2 RK_PD1 GPIO_ACTIVE_LOW>;
snps,reset-active-low;
/* Reset time is 20ms, 100ms for rtl8211f */
snps,reset-delays-us = <0 20000 100000>;
assigned-clocks = <&cru SCLK_GMAC1_RX_TX>, <&cru SCLK_GMAC1>;
assigned-clock-parents = <&cru SCLK_GMAC1_RGMII_SPEED>, <&cru CLK_MAC1_2TOP>;
pinctrl-names = "default";
pinctrl-0 = <&gmac1m1_miim
&gmac1m1_tx_bus2
&gmac1m1_rx_bus2
&gmac1m1_rgmii_clk
&gmac1m1_rgmii_bus>;
tx_delay = <0x4f>;
rx_delay = <0x26>;
phy-handle = <&rgmii_phy1>;
status = "disabled";
};
4.1.2. 板级的配置¶
kernel/arch/arm64/boot/dts/rockchip/rk3568-firefly-roc-pc-se.dtsi
&gmac0 {
status = "okay";
tx_delay = <0x4a>;
rx_delay = <0x2e>;
};
&gmac1 {
status = "okay";
tx_delay = <0x3e>;
rx_delay = <0x32>;
};
4.2. Android双以太网的使用¶
此设备的双以太网口分内网和外网。 内网又称局域网（Local Area Network，LAN，是指在某一区域内由多台计算机以及网络设备构成的网络，无法连通外部网络；外网为广域网，又称公网，是连接不同地区局域网或城域网计算机通信的远程网，可以连通外部网络，如访问百度，搜狗。
eth0 : 副网口，用于内网
eth1 : 主网口，用于外网
Android 系统Settings -> Network & internet -> Ethernet/Ethernet2， 可以查看主副网口的 IP 地址。
4.2.1. 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 eth0 eth0 Link encap:Ethernet HWaddr b2:d1:83:54:0e:62 Driver rk_gmac-dwmac inet addr:192.168.1.102 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::721f:ee30:f2a3:7bac/64 Scope: Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:189 errors:0 dropped:0 overruns:0 frame:0 TX packets:135 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:18349 TX bytes:7022 Interrupt:41
ifconfig eth1 eth1 Link encap:Ethernet HWaddr ae:d1:83:54:0e:62 Driver rk_gmac-dwmac inet addr:168.168.108.98 Bcast:168.168.255.255 Mask:255.255.0.0 inet6 addr: fe80::641:354:8888:73fe/64 Scope: Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2016 errors:0 dropped:0 overruns:0 frame:0 TX packets:41 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:128098 TX bytes:4374 Interrupt:51
4.2.2. 连通性测试¶
