file system

I build mini profile enviroment in custom board. The problem is that I can not login into system. I have try to use in MFG, it does not work.

But if I use ubuntu demo file system, it works well.

I think the problem is script about rc.conf or rcS,but I don't know how to modify it.If someone can give me a hint,that will be appreciated.

The syslog shows below.

EXT3-fs: barriers not enabled

What is the error on the MFG? BTW, the rootfs expected by MFG should end with bz2, not bz. Make sure the MFG's configuration matches the file you are placing on under the Profile folder.

I used rootfs.tar.bz2 built in the MFG.The u-boot.bin and uImage  are generated by ltib.

There is no error at the stage of downloading files. I can't login into file system when I input "root" in prompt freescale login:

as the same as I download these files by command dd. If I deselected the []boot up with a tty and login under ltib top menu,

the prompt shows that the currect user is root,but there is response yet if I input command.

I think the error caused by script. How do you think of this question?
