Lpc2000

Been working with LPC2138 with IAR just fine.  Trying to move to smaller
LPC2131.  When I download the same app it won't run to main.  Anybody do
this yet?  
 
I think I'm looking for the equivalent LPC2138.i79 and iolpc2138.ddf
(device description file) for the 2131.  Anything else?
 
Thanks, Jeff
