As long as you remember to program it before you solder it on and 
create a BRICK.
As long as you don't need to change the loader code.
As long as you don't need to debug the application with JTAG. 
All I'm saying is think of all the posibilities that can occur

In the last 35 years as a test engineer I've seen a lot of designers 
waiting for the paint to dry. :)
