sudo mount -t cramfs -oloop rootfs_cramfs.stb225_nand.bin /home/cnh01994/nfsroot/rootfs_stb225
然后copy auImage.stb225_nand到tftp目录，并且改名为load的kernal文件.
如果你使用其他的目录来做nfs的root，那么你可以打断原来的rootfs_stb225的链接，使它指向你自己的目录。使用完以后使用如下命令恢复rootfs_stb225到你的project指定目录
prjmake control sub=rootfs.nfsexport 如果你记不住命令，那么你可以执行prjmake control sub=rootfs.系统会列出来所有有关的命令如下：
=*=*=*=*=*=*=*=*=*=*=*= START stb225/control/pnx8335-stb225-le =*=*=*=*=*=*=*=*=*=*=*=
make -  rootfs cpu=pnx8335-stb225 env=stb225/control/pnx8335-stb225-le

Make-targets for rootfs:
make rootfs.help
make rootfs.clean
make rootfs.init
make rootfs.create
make rootfs.nfsexport
make rootfs.realclean
make rootfs.copy
rootfs.realclean                 - Remove your $ROOTFS tree

同样的对于kernal p_w_picpath，你可以使用prjmake control sub=linux.install来恢复project的kernal文件到tftp目录，同样你也可以使用prjmake control sub=linux来查看相关命令如下：
=*=*=*=*=*=*=*=*=*=*=*= START stb225/control/pnx8335-stb225-le =*=*=*=*=*=*=*=*=*=*=*=
make -  linux cpu=pnx8335-stb225 env=stb225/control/pnx8335-stb225-le
