本人刚接触嵌入式，碰到一个问题好多天没解决，网上很多人都碰到了类似的问题，但我这边按他们的方法解决不了问题。求大神解惑。

问题描述：
开发板nfs挂载ubuntu虚拟机失败。提示：
mount: wrong fs type, bad option, bad superblock on 192.168.1.2:/home/hjr/share/nfs,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so.

网上很多人碰到这个问题，都说要安装nfs-utils。但我这是开发板，安不上啊。

在开发板的/proc/filesystems下有nodev nfs和nodev nfs4。但是在/sbin下没有mount.nfs。

ubuntu虚拟机的nfs服务器测试OK。

开发板也可以ping的通主机：
root@firefly:/sbin# ping 192.168.1.2

好几天没弄好。路过的大神帮忙解解惑吧。。。
