Hi,
One possibility of this happening is when you forget the chown -R
<working directory> for the corresponding users.
This especially happens if you switch between root and <user>
frequently.
Try chowning the rootfs to the appropriate user once again.
Hope this may land up in some clue.
Cheers,
Deepak

Subject: TMS320DM355 DVEVM: Login problem
Hi every one,
I am having a problem that I can not login the target board as root
user, it always responds "login incorrect". I tried to open file
/etc/passwd and /etc/shadow and sure that the root user has no password.
I am using boot mode via TFTP using NFS file system and I also upgraded
the target to the newest version 5.0.0.0 and file system also. You can
see on the console:
