Agree that it's the wrong mailing list. 

However, to try and answer the OP's question: You shouldn't have to use -march, 
as that sets the architecture. You should just use the -mpart=uc3a0512 switch 
to set the device that you want to use. The archictectures of ucr1, ucr2, and 
ucr3 are just generic architecture names that select the instruction set to use.
