Hi!...I have problems when trying to compile at32uc3b demo project.

I have this screen:

I suspect most of your problems will relate the the first error: "../../BOARDS/EVK1101/led.c:46:22: error: avr32/io.h: No such file or directory"

However, note the UC3 port is old, and only works on old revisions of UC3 chips. Your best bet is to take a demo from http://asf.atmel.com
