这是为什么？？？
bin dev etc init lib linuxrc opt proc root sbin sys tmp usr var
我的文件系统明明就存在这个/init 文件。
下面是我的文件系统。 //这个文件系统在天嵌开发板上能够正常。自己弄的板子就不可以了。
bin dev etc init lib linuxrc opt proc root sbin sys tmp usr var
Jian Zhou：
请问你是在SD卡上启动，还是NAND FLASH。出现这种情况一般是文件系统不正常。

回复 Jian Zhou:
sd卡启动uboot后，
（1）复制文件系统到nand flash
fatload mmc 0 0x83C00000 root.binnand erase 0xa80000 0x3C00000 (60M )nand write.yaffs2 0x83C00000 0xa80000 0x3C00000
(2)设置启动环境变量
setenv bootargs console=ttyO0,115200n8 root=/dev/mtdblock8 rootfstype=yaffs2 rw rootwait=1 init=/init ip=off
这里有个奇怪现象： root=/dev/mtdblock8 把这个位置修改 root=/dev/mtdblock7 这位置后，应该是找不到这个位置？？？按照我的理解应该是cannot open mtdblock7。。。。（这里求指导一下）

(3) 然后将内核放到内存上运行
fatload mmc 0 0x82000000 uImage.bin
bootm 0x82000000
这是我操作的流程。出现上面的告警，挂载不上文件系统。
