from battery hole area, maybe we can find another place without changing 
more parts layout, but it's still need to evaluate.[3] This avt2 v1.0 
tried to keep most partly layouts same as Ben initially and verify 
different layout shape of jz4720. So now the new shape layout for die is 
work, so we can do step by step and change additional layout way on 
others parts as well. But we still need s/w hacker to help us to test 
the stability.

So we have now get 16 pcs {without glue die}can boot with 32MB SDRAM but 
4 pcs I am still debugging them.
Still working on this.
