Maybe my answer didn't reach the list.
I send it again...
See below.
Jul 23 12:59:35 freescale auth.info sshd[1816]: User igotre password
has expired (root forced)
This means that sshd found a zero in the sp_lstchg field in the
/etc/shadow file (if yours has the same layout as mine, it's the field
immediately after the encrypted password).
Yes, the field value was zero.
So what's happening is that sshd thinks your password has expired so it
runs "passwd", but passwd either isn't clearing the setting that says
that the password needs changing, or it's deliberately resetting it.
It seems that passwd doesn't do anything with that field. It remains zero
also after a password update.
Note that I'm using busybox passwd command an my board.
You can probably work around it by manually editing /etc/shadow to
remove the zero from that field.
Yes, I did this way and the problem has been solved.
Does your passwd program actually support the shadow password expiry
fields? If you run it from a shell, does it clear the field?
It doesn't affect the "password expiry field" as I told.
Oh, and since the sp_lstchg field is "days since Jan 1, 1970", does your
board have a clock, or does it think it's still in the 70s? If the
apparent date is still Jan 1, 1970 that would probably cause passwd to
write a zero to that field when a password is changed.
When the board starts it's in the '70s but I set up the correct date
by hand. At this time it goes this way... I'm still in the beginning stage
of my project development....

Jul 23 12:59:35 freescale auth.err sshd[1821]: error: open /dev/tty
failed - could not set controlling tty: Permission denied
That's a separate problem but probably unrelated: the permissions on the
/dev/tty device special are probably wrong. It should be mode 666.
Yes, this was a completely different matter and I could solve it in
the meanwhile
changing the file permission of the tty device as you said.
Thanks a lot Darren for your detailed and clear answer.
Igor.
