3.1.3. View IP Address¶
Double The Ethernet port is connected to the network. You can check the IP address through the debug serial port or adb, such as
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
