LCD shows colored screen

Hello, after i formatted the NAND flash using dnw, i see a colored screen
on LCD (white-black with some vertical lines)
how to repair that ??
also is there any way to reset mini6410 or initialize factory settings for
NAND Flash? after that, i decided to use H-JTag. it detected SAMSUNG chip
but when i wanted to erase the nand flash it says the device is not
connected properly...
my mini6410 now is useless ):
please give me some instructions to define the nand flash just likes
factory. sorry for poor English.

The Mini6410 is programmed from SD cards. You need to prepare and SD card
with the images for the kernel and file system + superboot. Try this

thank you for reply. i already see this link but the link didn't say about
details of u-boot_XYZ.bin
i don't know how to use u-boot_nand-ram256.bin and u-boot_sd-ram.bin and
what is difference between them exactly ?
where to copy these files, is it must be fused to SD-Card ?
and how to config ini file with u-boot_XYZ.bin
(i already fuse superboot-6410.bin,u-boot_XYZ.bin in separated stages
but it had same problem.)
can you help me plz?

Hi Hesam i have same problem with my LCD but i write the nand flashwith SD
flash...
you should copy 2 files to your SD...one of them is your .bin file, for
example called main.bin
and the other one is a FriendlyARM.ini

and edit it:

Action=install
OS= UserBin
StatusType = LED 
############### UserBin part #################
UserBin-Image=mini6410-led.bin
userBin-StartAddress=0xC000000

you should copy them to the (H:\images) folder on your SD
in additional you have to load superboot.bin on your SD with SD Flasher at
first.
these document are available in your mother board CD...
good luck
