Problem loading linux

Chemapo
Hi,

I have a micro2440 sdk and a mini2440. I'm trying to load my own kernel to
micro2440 but i'm having some problems. Using dnw i erase nand (x) then
load supervivi (for 128 MB board), then zImageN35 and then root_qtopia (128
mb board). If i use the pre-compiled zImage that is on the cd all works
fine. 

Now i have gcc4.2 and linux 2.6.29 (downloaded from the site) on my centos
5 pc, i copy the mini2440_n35 config file to .config then i compile the
kernel, kernel succesfully compiles and zImage is succesfully generated but
when i try to load this image using dnw the kernel doesn't boot up.

Please could you tell me if i'm missing some step or something?

Regards

gcc 4.2 or gcc 4.3.2?
