Unable to modify from U-Boot to Qi.

[ramsarvan]

Hi Andy,

Sorry for not making it clear.

Actually what happens is:

1) When I try booting 
(after flashing Qi into NAND from NOR flash mode and inserting SD card 
with ext3 partition containing Android images) by pressing the
Power button for 10 secs, the device stops at the splash screen.
Then I did cu to check what happened, I got the following:

NAND read: device 0 offset 0x880000, size 0x5000
 20480 bytes read: OK
Hit any key to stop autoboot:  0 

NAND read: device 0 offset 0x80000, size 0x200000
 2097152 bytes read: OK
## Booting kernel from Legacy Image at 32000000 ...

              36 append-GTA02
         2533736 uImage-GTA02.bin

It reads from NAND flash and not from SD card.
So it fails to read from SD and tries reading
from NAND. I dont know why.

2) After flashing QI, NAND menu should not occur
as per wiki, but i see NAND menu when I press 
Power first aux next. I dont know why? Dont know
whether I have flashed Qi or not?

Thanks
Ram
