Thanks pointing me to the right direction. 
I think I got it. 

Old u-boot might be NOT support uImage larger than 2M.
I need to update u-boot (Nand) to support uImage(>2MB).

If my understanding is wrong, please correct me. thanks.

BTW, can I moniter u-boot process though usb (which can access the
u-boot commands) without debug board? 

Please point me to the right direction. A link will be do ;)

Thanks very much!
