U-boot mini2440 128 MiB Nand

Hello,

I have been trying to port a U-boot to a MINI2440 for last two weeks.
But So many problems are there.

The error is
nand_scan() cannot allocate buf

Please Help me to solve the problem

There is a Git tree.There is a workaround on making it work

Here is the Procedure.

1)Boot from NOR Flash
2)Download and Run uboot-nand2k.bin after compiling from the git tree.
3)Do nand scrub,createbbt.
4)!!IMPORTANT!! Reset the board and boot into NOR flash.
5)Select the Download Vivi option and download uboot-nand2k.bin
6)Reset into NAND Flash.
7)uboot boots up then run "dynenv set 40000"
8)run saveenv
9)You should see a Writing to NAND.

Setup is complete

I am newer in Embedded Linux
