I realized about the Bad CRC warning afterwards. Anyway, the U-Boot
after that message and I do not see stdout, stdin and stderr that should
come up 
on the console. How can I change that to my target LCD? I know that
stdin cannot
be LCD, it has to be UART, But how can I change stdout to LCD? Can any
one help?

This warning is nothing to worry about; it just means you have not saved
a copy of your environment into flash.  The built in defaults will be
used then.  If you do a 'saveenv' then reboot the message will go away.
It's a little more work in a production sense to program up a proper
per-device value but its doable, though a little harder for things like

In the past I have added such support into u-boot for an OMAP device.
That code likely would be a good starting point and probably would work
with a few tweaks.
