iTOP-i.MX6开发板_V2.7.1 网络问题

官方提供的 1.imx6q光盘资料\04 源码_android 4.4文件系统这套源码功能不完整？
使用这套源码调试EIM接口发现内核未初始化EIM接口，增加初始化后正常
现在继续调试网络，怎么都调不通，连ping开发板或开发板ping主机都不通【开发板IP 默认是192.168.1.230，我的主机是192.168.1.55】
[root@iTOP-iMX6]# ip addr show dev eth0
3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000

link/ether 08:90:90:90:90:90 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.230/24 brd 192.168.1.255 scope global eth0

[root@iTOP-iMX6]# PHY: 1:00 - Link is Up - 10/Full

[root@iTOP-iMX6]# ping 192.168.1.55
PING 192.168.1.55 (192.168.1.55): 56 data bytes

这里就不动了，等待一段时间后出现下面打印》》
