问题:
eth0采用dhcp方式获取ip，启动的时候是可以获取到的

done.
可以ping通网关

进入系统以后 ，执行
ifconfig eth0 down
ifconfig eth0 up
出现以下显示
[ 347.538091] net eth0: initializing cpsw version 1.12 (0)

ifconfig也能够也显示获取到了ip

回复 leo chen:
后面的DHCP没获取到IP啊，用Wireshark抓个包看一下，后面失败的原因是DHCP请求没法出去，还是Server端没回应，亦或者是收到回应后板子这边没应答。

回复 Gary Wu:
非常感谢你的回复，不过EVM的网络接口和beaglebone black的网络接口 硬件不一样的，一个是千兆，一个是百兆
难道是硬件设计的问题？
谁有BBB的板子，可以试一下啊，非常感谢

回复 leo chen:
你好，你的问题解决了么，我重新移植的内核也出现了这个问题，然后网卡就废了，感觉像是找不到网卡配置信息？我之前用BBB是没有这个问题的，现在用的BBG才出现这个问题，而且比较频繁

回复 yongt chen:
对比一下BBB的内核配置文件，可能网络配置不同
