Try change it to
bootargs=root=/dev/ram rw console=$consoledev,115200
and if you need change console then change consoledev environment variable

Ok on kernel boot up I got
*Kernel command line: root=/dev/ram rw console=ttyS1,115200*

That means it didn't changed

As per your saying I did following things
=> setenv console ttyS0
=> savenv
Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash... done

setenv console ttyS0
then
saveenv
end reboot board
Hope this help.

Is this question is after seeing this line

*_Well before making any changes I am getting

when I made

In /etc/intab it was

/command prompt is not visible it get stuck here

/Is there any command where I can show for

My MPC8xxx uses ttyS0 and I am pretty it's
external DB9
is not
connected and jumpered to an internal header
(by default).

ttyS1 is an odd tty for the console. Are
you sure
you are
connected
to ttyS1? Are you sure ttyS1 is brought
out to the
external
connector,
if there one?

My MPC8xxx uses ttyS0 and I am pretty it's
external DB9 is not
connected and jumpered to an internal
header (by
default).
