I don't think that you compiled the _ELDK_!

I hope with "used" you mean that you made sure it is NOT set.

You make a fundamental error. You're using an U-Boot configuration
which has not been correctly ported and configured to your board, and
you're using a Linux kernel which has not been correctly ported and
configured to your board.

This cannot work. Go back to square 1.
