You will need to add more RAM too, so that the image can be loaded
into it (currently starting at (iirc) 0x31000000) without being
overwritten by u-boot stack and u-boot itself at (iirc) 0x33f80000
before it is read by u-boot and written to NAND. You would face
exactly the same problem on a real hardware with dfu-util (writing to
Andrzej (away until September(?))
