4.5 以太网驱动调试
4.5.1 RTL8211F调试
4.5.1.1 查看原理图, 获取配置信息图1
图2
图3
图4
4.5.1.2 需要配置的信息如下
1、RTL8211F是挂载到gmac0上的
2、RTL8211F采用的是rk3568内部的时钟
3、RTL8211F的复位引脚是GPIO1_B0, 且是低电位有效
4、RTL8211F的地址是1
5、RTL8211F是工作在RGMII模式 4.5.1.3 RTL8211的完整配置&gmac0 { phy-mode = “rgmii”; clock_in_out = “output”; snps,reset-gpio = <&gpio1 RK_PB0 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>; assigned-clock-rates = <0>, <125000000>; pinctrl-names = “default”; pinctrl-0 = <&gmac0_miim &gmac0_tx_bus2 &gmac0_rx_bus2 &gmac0_rgmii_clk &gmac0_rgmii_bus &gmac_rst>; tx_delay = <0x3c>; rx_delay = <0x2f>; phy-handle = <&rgmii_phy0>; status = “okay”; }; &mdio0 { rgmii_phy0: phy@1 { compatible = “ethernet-phy-ieee802.3-c22”; reg = <0x1>; }; };<
4.5.2 YT8511C调试
4.5.2.1 查看原理图，获取配置信息图5
图6
4.5.2.2 需要的配置信息如下
1、GMAC1用的是GMAC1_M1组的IO
2、复位引脚是GPIO3_B0
3、YT8511时钟是由晶振直接提供的，但又没有通过PY8511C给到rk3568, 所以即要用内部时钟，否则RK3568的内部phy就没有phy时钟了。
4、通过phy的地址为0b00100,即地址为4
5、YT8511C用的是RGMII接口 4.5.2.3 完整配置&gmac1 { phy-mode = “rgmii”; clock_in_out = “output”; snps,reset-gpio = <&gpio3 RK_PB0 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>; assigned-clock-rates = <0>, <125000000>; pinctrl-names = “default”; pinctrl-0 = <&gmac1m1_miim &gmac1m1_tx_bus2 &gmac1m1_rx_bus2 &gmac1m1_rgmii_clk &gmac1m1_rgmii_bus &gmac1_rst>; tx_delay = <0x32>; rx_delay = <0x09>; phy-handle = <&rgmii_phy1>; status = “okay”; }; &mdio1 { rgmii_phy1: phy@4 { compatible = “ethernet-phy-ieee802.3-c22”; reg = <0x4>; }; };<
4.5.3 以太网测试
4.5.3.1 查看是否有以太网节点rk3568_aybering:/ # ifconfig eth0 Link encap:Ethernet HWaddr ce:7e:e7:30:dd:5a 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:43 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope: Host UP LOOPBACK RUNNING MTU:65536 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 eth1 Link encap:Ethernet HWaddr ca:7e:e7:30:dd:5a 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:55 dummy0 Link encap:Ethernet HWaddr 6e:57:01:1d:92:d9 inet6 addr: fe80::6c57:1ff:fe1d:92d9/64 Scope: Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 TX bytes:350 rk3568_aybering:/ #<
可以看出，有两个以太网节点
4.5.3.2 测试eth0将网线插入J17网口，等待一会后就会可以看到在状态栏（右上角）有以太网连接的图标<—->。执行命令查看IP地址和检查是否可以连网
