Hi Everyone,
I am try to use the u-boot to program the NOR flash on my proprietary
board based on AMCC sequoia board. I can boot from 1Gb NAND flash ok
but everytime I try access the last 4K of NOR flash, U-boot gives me
following error and reboots:-
{{{

I get the same error if I press "ENTER" after u-boot gives me the
prompt. If I type some command its ok and then its fine thereafter.
I know the NOR flash is ok because I used BDI to program it and also I
can access this address when I boot from NOR flash.
Any Clue?
Thanks In Advance!
