Please restrict your line length to some 70 characters or so.

And please provide more dsetails: what exactly is your board name, and
which exact version of U-Boot are you running on it?

Please also show the corresponding boot messages of the Linux kernel
so we can see how which partition is where, on which device, etc.

Argh... Your mix of your text and quoted command output is basically
unreadable.  Please try and make your mails a bit easier to read.

Apparently your config file is wrong, but you don't provide enough
information to spot the actual issue.

In any case your flash sector size (2 MB) is totally bogus.
