Check your setting for /dev/console, it should read:

[root at other images]# ls -l /it/dev/console
crw-------    1 root     root       5,   1 Dec 31  1969 /it/dev/console

Note that the major number is 5.

Also, make sure that you assigned a console in /etc/inittab:

# inittab for uClinux
# Format:
# ttyline:termcap-entry:getty-command
inetd:unknown:/bin/inetd
# boa:unknown:/bin/boa
ttyS0:vt100:/bin/agetty 115200 /dev/ttyS0

ALSO(!) Don't assume that anything is understood by the members of the
list:

1.  Give a complete capture of the boot messages.

2.  What distro did you begin with?  uClinux-Coldfire,
uClinux-distribution-20010622, uclinux-2.0.38-pre4, ...

3. etc...
