mount连接不上arm开发板，很急，先谢谢了

机器装的是红旗桌面6.0
实验箱用的是s3c2410

用一根网线直连进入箱子
无法mount
提示信息为：
# mount 192.168.1.180:/tftpboot /mnt/nfs
mount: 192.168.1.180:/tftpboot failed, reason given by server: Permission denied
mount: nfsmount failed: Bad file descriptor
mount: Mounting 192.168.1.180:/tftpboot on /mnt/nfs failed: Invalid argument
# Connection closed by foreign host.

再次谢谢各位
