Loading uboot on 1Gb Nand

Hi ,
i have purchased mini2440 with 1Gb Nand, it came with Wince loaded onto it,
now i want to load it with uboot. can any one plz help me on it.

Currently i am using windows platform with DNW and tftpd32 for loading it.

The following were the step by me to load kernel.

   1. Powered mini2440 on NOR mode.
   2. Selected v option and loaded uboot1gb.bin using DNW thro USB.
   3. Switched to nand mode and reset the board.


In: serial                                              
Out: serial                                             
Err: serial                                             
MAC: 08:08:11:18:12:27                                  
Hit any key to stop autoboot: 0                           

after the above appeared on hyper terminal, i entered the following cmds.

MINI2440 # setenv serverip 10.0.0.4
MINI2440 # setenv ipaddr 10.0.0.2
MINI2440 # setenv bootfile uImage
MINI2440 # setenv loadaddr 0x32000000
MINI2440 # saveenv

   1. Selected 10.0.0.4 address on tftp.      
   2. In tftp window, clicked on BROWSE tab and have selected path to
Image/Linux.
   3. Then Clicked Show Directory to load kernel image, selected uimage.bin
and clicked OK Tab

MINI2440 # tftp

As soon as i enter # tftp cmd, i receive the error saying "TFTP ERROR: 
File not found"
                                                                           
               Starting again.
