4.1.2. 板级的配置​

        phy-mode = "rmii";
        clock_in_out = "input";

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

    root@rk3506-buildroot:/# ifconfig eth0 eth0 Link encap:Ethernet HWaddr C6:A3:0A:E9:63:59 inet addr:172.16.10.201 Bcast:172.16.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:131 errors:0 dropped:20 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:16537 (16.1 KiB) TX bytes:810 (810.0 B) Interrupt:49 Base address:0x6000

    root@rk3506-buildroot:/# ifconfig eth1 eth1 Link encap:Ethernet HWaddr CA:A3:0A:E9:63:59 inet addr:172.16.10.203 Bcast:172.16.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:70 errors:0 dropped:12 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:10235 (9.9 KiB) TX bytes:810 (810.0 B) Interrupt:51 Base address:0x4000
