4. Ethernet 使用¶
4.1. dts 配置¶
4.1.1. 公共的配置¶
gmac: ethernet@21c70000 {
compatible = "rockchip,rv1126b-gmac", "snps,dwmac-4.20a";
reg = <0x21c70000 0x10000>;
interrupts = <GIC_SPI 200 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 197 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "macirq", "eth_wake_irq";
rockchip,grf = <&grf>;
rockchip,php_grf = <&ioc_grf>;
clocks = <&cru CLK_GMAC_125M>, <&cru CLK_50M_GMAC_IOBUF_VI>,
<&cru PCLK_GMAC>, <&cru ACLK_GMAC>,
<&cru CLK_GMAC_PTP_REF>;
clock-names = "stmmaceth", "clk_mac_ref",
"pclk_mac", "aclk_mac",
"ptp_ref";
resets = <&cru SRST_ARESETN_GMAC>;
reset-names = "stmmaceth";
snps,mixed-burst;
snps,tso;
...
4.1.2. 板级的配置¶
kernel-6.1/arch/arm64/boot/dts/rockchip/rv1126b-firefly-aio-1126bjd4v0.dtsi
#ifdef FF_GMAC
&gmac {
phy-mode = "rgmii";
clock_in_out = "output";
snps,reset-gpio = <&gpio5 RK_PA6 GPIO_ACTIVE_LOW>;
snps,reset-active-low;
/* Reset time is 20ms, 100ms for rtl8211f */
snps,reset-delays-us = <0 20000 100000>;
assigned-clocks = <&cru CLK_MAC_OUT2IO>;
assigned-clock-rates = <25000000>;
pinctrl-names = "default";
pinctrl-0 = <ðm1_miim_pins
ðm1_tx_bus2_pins
ðm1_rx_bus2_pins
ðm1_rgmii_clk_pins
ðm1_rgmii_bus_pins
ð_clk_25mm1_out_pins>;
tx_delay = <0x2f>;
rx_delay = <0x2d>;
phy-handle = <&rgmii_phy>;
status = "okay";
};
&mdio {
rgmii_phy: rgmii-phy@0 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <0x0>;
clocks = <&cru CLK_MAC_OUT2IO>;
};
};
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 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
ifconfig eth1 eth1 Link encap:Ethernet HWaddr 32:0a:d2:60:c9:05 Driver rk_gmac-dwmac inet addr:168.168.101.38 Bcast:168.168.255.255 Mask:255.255.0.0 inet6 addr: 240e:3b1:f174:f00:d3fe:4d8e:fda9:3c0/64 Scope: Global inet6 addr: fe80::b556:9d3f:e684:bec4/64 Scope: Link inet6 addr: 240e:3b1:f174:f00:9d78:e75f:6167:15c1/64 Scope: Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:913 errors:0 dropped:1 overruns:0 frame:0 TX packets:210 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:108473 TX bytes:24906 Interrupt:127
4.1.4. 连通性测试¶
