然后就一直在那里不动了？请问是哪里出了问题呢？是挂的硬盘出问题了吗？
jm luo：
有大侠可以指导一下吗？
Chris Meng：
回复 jm luo:
你好，
能否用ip=dhcp尝试一下？
如果是静态IP，请尝试ip={ ipaddr }:{ serverip }:{ gatewayip }:{ netmask }:{ hostname }::off
jm luo：
回复 Chris Meng:
应该不是DHCP的问题，板子原来的好的，用着用着就变成这样了。
Eason Wang：
回复 jm luo:
有没有尝试重烧binary？
jm luo：
回复 Eason Wang:
是重烧 u-boot-dm6467t-evm.bin 和 uImage-dm6467t-evm.bin 吗？
junliang zhang：
回复 jm luo:
你好请问你这个问题解决了么，我现在也遇到了
kooking：
回复 junliang zhang:
可能的情况：
1.bootargs参数配置不正确，可以检查确证一下
2.文件系统已经损坏，重新烧写一下镜像文件
