I realized about the Bad CRC warning afterwards. Anyway, the U-Boot hangs 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?
Thanks, Jigisha

Hello,
*** Warning - bad CRC, using default environment
This message is coming from common/env_common.c file. Can anyone help
me
identify the mistake?
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 NAND.
Is that all I have to do to enable my target LCD within U-Boot? My
goal
is to be able to write images on the LCD verify if it is OK.
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.
