DM385的板子，原来是用nfs挂在文件系统的，能正常运行
bootargs=root=/dev/nfs console=ttyO0,115200n8 mem=54M rw notifyk.vpssm3_sva=0xBFD00000 nfsroot=192.168.86.253:/opt/prj/dm385/sdk/Source/ipnc_rdk/target/filesys,nolock,tcp ip=dhcp eth=00.0C.0C.02.38.45 cmemk.phys_start=0x83600000 cmemk.phys_end=0x85600000 cmemk.allowOverlap=1 earlyprintk
现在使用nand上的文件系统：
setenv bootargs console ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=54M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=dhcp eth=$(ethaddr) cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk
确定nand上有文件系统，仅仅更改了bootargs，其他的一切都没有变，可怎么也启动不了。

就在这个地方停了下来，试了很多，都还是这样！
有谁知道如何解决这个问题吗？谢谢了！
