imx6ullemmc开发板通过NFS挂载内核、设备树一直显示Loading: T T T T T T T T T T的问题

首先是基础配置我是使用的ubuntu实体机其有两个不同的网段，一个有线网段 ip（192.168.2.73）一个无线网段 ip (192.168.1.73),无线网段用于与笔记本ssh链接，有线网段用于与开发板链接，在此前提下我的ssh链接正常，ubuntu主机 ping www.baidu.com正常可连接，ping笔记本可正常连接，imx开发板ping   ubuntu的有线网段 ip（192.168.2.73）可通，ping无线网段 ip (192.168.1.73)提示Using FEC1 device## Warning: gatewayip needed but not set
host 192.168.1.73 is aliv
由于使用的是有线网段，故我直接忽略后续操作直接访问nfs
=> nfs 80800000 192.168.2.73:/home/tt/linux/nfs/zImage
Using FEC1 device
File transfer via NFS from server 192.168.2.73; our IP address is 192.168.2.74
