关于嵌入式Linux启动过程的问题
各位大虾，请教一个linux启动过程的问题
本人用的dm365，移植文件系统后，添加自启动语句，平时跑的好好的，有时会突然启动到一半就停住不动了，且一旦出现上述情况，以后每次启动都这样，系统没有死，在串口敲回车还有反应，一下是正常启动和非正常启动的部分打印
正常

其中打印上出的111、2222、@@@、####等是我在一些配置文件中加的打印，“CMEM....”是我应用程序启动前加载的部分驱动
我看了下两个启动过程，若是能打印“INIT: Entering runlevel: 5”（系统默认登陆级别是5）则能正常启动，但是若换成登陆级别6的话，非正常启动的板子会重启，说明，它是进入了该级别运行了。搞了好些天没整理出头绪来，希望各位大虾指导下感激不尽，刚申请的号，没多少分，见谅。
若需要其他信息，请留言，我会贴下，谢谢各位！！！ Linux 启动过程 嵌入式 启动级别
[解决办法]
没细看你的log。你为啥要改init 6。 init 6就是相当重启。
[解决办法]
有几处No such file or directory，是不是文件系统挂载有问题
[解决办法]
应该是文件系统挂载有问题文件系统挂载有问题
