I gave up trying to reply to your questions. You supply _zero_
information. We don't know which board this is, which exact version
of U-Boot you are running on it, which modifications you made to the
code you are running, how you configured and built U-Boot for this
board, what the MTD configuration in your Linux kernel is, nor how
you set up the fw_env configuration file, etc. etc. etc.

You must not expect any help without providing essential information.
I explained this to you before here:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/64344
and here:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/68424A
and again here:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/68521

All you told us was that you are running some heavily modified code
based on a 5 year old version of U-Boot.

I then told you that we will not waste efforts in supporting such old
code.


No matter how often you will ask the same questions again: we _cannot_
help you in this situation.

Update and use current code, please. If you cannot do this yourself,
then hire someone who can. Please feel free to drop me a note when you
need help with this, but note that this help will not be available for
free.

Also, reading http://catb.org/esr/faqs/smart-questions.html might be
beneficial to you.

Best regards,

Wolfgang Denk
