Can i run application developed in QT 5 on Qtopia 2.2.0 on ARM9

I'm planning to develop a program in QT 5.X

I have a Mini2440 Board with QTopia 2.2.0 on it.

Will i be able to run it on the board?

I recall some old threads about people trying to run QT 4.x apps while they
still had 2.2.0 on the target.  Search <qt 4.6.2 qtopia 2.2.0> there is a
whole page of hits.

Good luck!
