各位高手好，这个系统就卡在Kernel panic - not syncing: No init found. Try passing init= option to kernel这里，进不了。我已经搞了一个星期多了，五一也没得放假啊。
我想请问各位高手：这个系统问题出在哪里，是内核吗，还是根文件系统呢
内核的
Boot options --->
noinitrd root=/dev/mtdblock2 rootfstype=yaffs console=ttySAC0,115200 init=/linuxrc mem=64M) Default kernel command string
我烧学的根文件系统是yaffs.img
我也试过：
Boot options --->
noinitrd root=/dev/mtdblock2 rootfstype=cramfs console=ttySAC0,115200 init=/linuxrc mem=64M) Default kernel command string
我烧学的根文件系统是root.cramfs
但都是不行
想请问下面几行是什么意思，对根文件系统有什么影响：
yaffs: dev is 32505858 name is "mtdblock2"
yaffs: passed flags ""
