如图:
原因:nfs模块未配置加载到内核中。
解决办法:加入nfs模块到内核中,重新配置
配置如下:
File systems --->
[*] Network File Systems --->
<*> NFS client support
[*] NFS client support for NFS version 3
[*] NFS client support for the NFSv3 ACL protocol extension
[*] NFS client support for NFS version 4 (EXPERIMENTAL)
[*] NFS client support for NFSv4.1 (DEVELOPER ONLY)
[*] Root file system on NFS
[*] Networking support --->
Networking options --->
[*] IP: kernel level autoconfiguration
配置完后编译uImage
make uImage
重新烧写内核
