Problem with NAND flashing qt image on mini2440

Hello friends,
I m a new user with little knowledge to play with mini2440.
I have a mini2440 with 64MB NAND flash.

I want to set qt environment on it. (either with qtopia or opie)
I have my own OpenEmbedded environment with bitbake ,etc. toolchains set.
Got from here: (http://code.google.com/p/mini2440/wiki/OpenEmbedded) 

I created console-image , trolltech-qtopia-core-gui-image-mini2440 ,
qt4-image-mini2440 and opie-image successfully  in my openembedded
environment , with all their jffs2 and etx3 files.

My kernel is -> uImage-2.6.31+git-r9-mini2440.bin

But when I NAND flash my jffs2 file system (any of
qt4i-mage-mini2440,trolltech-qtopia-core-gui or opie image), i can't get
display on mini2440. I only get a console login for it.

For NAND flashing , i followed the instructions mentioned here:
(http://narnia.cs.ttu.edu/drupal/node/131)

Also, when I set kernel parameters to tell mini2440 to take SD card as
filesystem drive, it refuses to read from SD card, but for NAND flashing it
can COPY my jffs2 files from SD card successfully.


Here is an output when flashing opie-image on
mini2440:(http://pastebin.com/m7cdffa73)

Here is output when flashing trolltech-qtopia-core-gui on
mini2440:(http://pastebin.com/m106e8671)

Plz help me................

I have same problem with OpenEmbedded images like x11-gpe-image with 7"
MINI2440: after power-on LCD stays white and has some random vertical
stripes. Only serial port gets console output. If I restore the backupped
factory Qtopia image to the NAND then it works again, so it's not a DC
power issue. I'm using uboot and kernel 2.6.31 from repo.or.cz mini2440.git
repository.

Do I need to enable the LCD display output by writing to some node in /dev
or /sys filesystem during init?

Fixed. In case of 7" LCD must supply mini2440=1tb kernel parameter.
