u-boot and qtopia on NAND

Hi all,

I bought this board a few days ago and i'm having some trouble to
restore the default Qtopia image that a got from the shipped CD.
I would like to boot QTopia from u-boot and not use vivi.

I'm new in this embedded world and really need some help.
I have a mini2440 128M.

Files used:
u-boot-128M.bin
uImage
root_qtopia-128M.img

I can load u-boot on the NAND, also downloaded the kernel uImage and got no
errors.
When a i try to download the root_qtopia-128M.img from SD it gets stuck.

MINI2440 # fatload mmc 0:1 0x31000000 root_qtopia-128M.img
reading root_qtopia-128M.img   <--- stuck here

I followed the steps on the link below but insted of using GPE i tried
QTopia because the link that points to the binarys for this tutorial seems
to be broken.

Would help if anyone could send me some images that works, just for me to
test the procedure of changing the environment. 

Many thanks in advance.

you have tu install the yaffs image by supervivi.. 
but you need a uImage of your kernel if you want to boot with u-boot

Thanks klom for the reply.

So i have to download the root_qtopia-128M.img by vivi? 
[y] Download root_yaffs image 

Is there a way to do this by u-boot?

what about the kernel? 
Could it be the uImage i already installed by u-boot or do i have to
install a new zImage_N35(example) also by vivi?

I know this is probably a basic question but i really need something to
start with.

Thanks..
