In allegato trovate il core Tiny 0022 modificato per il supporto al 4313.
Scompattate l'archivio e sostituite la cartella ottenuta a quella presente in /hardware/tiny/cores.
A me compila senza problemi, però ho avr-gcc 4.3.5, tengo a precisare.
Dovete anche creare una board virtuale nel file /hardware/tiny/boards.txt.
Come test io ho usato questa:
