It might help if you specified which version of U-Boot you run and for
which board it is built.
Note that if you're not using the mainline U-Boot but a custom vendor
one, you should inquire with the vendor.
Note also that if you're using the mainline U-Boot, then you should make
sure you're using the latest version.

Hello Albert Aribaud,
Thanks for your reply.
The board contains LSI ARM processor and the U-boot is customised for the
same.
Regards,
Balaji.

I think that your Environment is in NAND, and as there is
no NAND, u-boot couldn;t find an environemnt ...
Please send the u-bot version and on which board you use, so we maybe
can help you!
bye,
Heiko

Hm... Did you try google?
If you search for "Warning - bad CRC, using default environment"
google will show the relevant entry in our FAQ as the very first hit.
It's really quite difficult to miss that, and I kind of admire how you
manage to do that.

As Albert already wrote: without any information about CPU type,
board name, origin and version of the U-Boot code you are using it is
impossible to answer this question.
