 mini 2440 nfs 挂载文件系统出错(rootfs_qtopia_qt4-20140103.tar.gz)

内核和bootloader 都是原装烧录好的。 我想通过nfs 挂载文件系统 结果出现如下错误:

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "<NULL>" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:
1f00             256 mtdblock0 (driver?)
1f01             128 mtdblock1one_wire_status: 4
(driver?)
1f02            5120 mtdblock2 (driver?)
1f03          256640 mtdblock3 (driver?)
1f04          262144 mtdblock4 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
