imx6啓動網卡以及IPV4方式

操作步驟

 01、進入開發板命令行，輸入 ifconfig -a 查看當前開發板網卡信息

       參考內容

root@imx6qdlsolo:/etc# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 82:B4:42:7D:59:A3  
          inet6 addr: fe80::80b4:42ff:fe7d:59a3/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:28 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:8107 (7.9 KiB)  TX bytes:648 (648.0 B)

lo        Link encap:Local Loopback  
          LOOPBACK  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:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

sit0      Link encap:IPv6-in-IPv4  
          NOARP  MTU:1480  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:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

wlan0     Link encap:Ethernet  HWaddr CC:B8:A8:1D:1E:B6  
          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 (0.0 B)  TX bytes:0 (0.0 B)

root@imx6qdlsolo:/etc# 

02、結合查看的網卡信息，輸入 ifconfig eth0 up，等待網卡啓動完成

      說明

             啓動網卡發現是以ipv6方式啓動，參考下面的解決辦法

     參考內容

root@imx6qdlsolo:/etc# ifconfig
eth0      Link encap:Ethernet  HWaddr 82:B4:42:7D:59:A3  
          inet6 addr: fe80::80b4:42ff:fe7d:59a3/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:28 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:8107 (7.9 KiB)  TX bytes:648 (648.0 B)

03、輸入命令 udhcpc -i eth0     ，以自動獲取IP地址方式啓動網卡

     參考內容

root@imx6qdlsolo:/etc# udhcpc -i eth0
udhcpc (v1.22.1) started
Sending discover...
SW4 loosen
sw5 close
SW3 close
Sending select for 192.168.1.150...

/etc/udhcpc.d/50default: Adding DNS 192.168.1.1
root@imx6qdlsolo:/etc/sysconfig/network-scripts# ifconfig
eth0      Link encap:Ethernet  HWaddr 8A:0B:3F:28:0F:0E  
          inet addr:192.168.1.150  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:25 errors:0 dropped:0 overruns:0 frame:0
          TX packets:14 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:8344 (8.1 KiB)  TX bytes:1652 (1.6 KiB)
