我属于嵌入式方面的小白，现在使用nanopi-m4 2GB 开发板，通过uboot引导启动linux，并使用NFS加载busybox构建的根文件系统。
搭建的NFS服务使用其它PC平台或uboot中的nfs命令都可正常访问，uboot、linux、busybox都使用的最新版源码。
1、使用ubuntu搭建的NFS服务端，防火墙已关闭
NFS /etc/exports 配置如下：
/home/gx/Downloads/nfs_root *(rw,sync,no_subtree_check,no_root_squash)NFS 查看支持的版本 sudo cat /proc/fs/nfsd/versions 输出如下：
sudo cat /proc/fs/nfsd/versions
+3 +4 +4.1 +4.22、linux内核编译时已经开启以下配置：
Networking support
- Networking options
- TCP/IP networking
- IP: kernel level autoconfiguration - IP: DHCP support
- IP: BOOTP support
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
- NFS client support for NFSv4.1
- Root file system on NFS3、uboot环境变量bootargs配置如下：
bootargs=console=ttyS2,1500000 rootwait root=/dev/nfs init=/linuxrc rw nfsroot=192.168.2.2:/home/gx/Downloads/nfs_root/rootfs_2 ip=192.168.2.3:192.168.2.2:192.168.2.1:255.255.255.0::eth0:off debug loglevel=8 nfsrootdebug4、使用uboot nfs测试NFS服务访问否正常，日志如下：
=> nfs 0x20008000 192.168.2.2:/home/gx/Downloads/nfs_root/rootfs_2/a.txt
Speed: 1000, full duplex
Using ethernet@fe300000 device
File transfer via NFS from server 192.168.2.2; our IP address is 192.168.2.3
Filename '/home/gx/Downloads/nfs_root/rootfs_2/a.txt'.
Load address: 0x20008000

done
Bytes transferred = 8 (8 hex)在uboot 运行uImage启动linux并加载根文件系统时总是有问题，linux日志如下：
Environment size: 1646/32764 bytes

有人说可能是linux启动时网卡未能正确驱动导致，我不知道该怎么验证此说法，是否能够给出一些验证此说法的操作方式。
希望能够通过NFS挂载根文件系统，在此感谢能提供帮助的朋友。
