看这个
[ 1.621307] Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
应该是没有指定内核启动参数或参数错误吧

制定的了

内核没问题的话，看一下文件系统有没有少东西。/sbin/init,/bin/init,/bin/sh

usecool 发表于 2014-7-7 17:41
mmcrootfstype=ext4 rootwait

完整的如下，也不行，一样的现象

先试试网络文件系统是否能够启动，如果可以，再试试烧写到Flash是不是也可以，如果都没问题，看看内核镜像是不是有问题。

usecool · 发表于 2014-7-8 10:39:46

先用ramdisk启动（ram文件系统）

我估计是没按正确的方法烧进去，还有你确定是烧到/dev/mmcblk0p2里了？这个字有没有写错？

看你这个NFS没问题，那你看看内核镜像是不是支持你的文件系统，再看看制作的文件系统是不是有问题，记得文件系统制作工具好像有错误，需要自己修改，最后看看是不是烧写有错误。
