upload wild-thumper

problen uploading wild-thumper

Hi everyone!!!

I've been tried to upload my wild thumper but when it's imposible. I tried with arduino relax patch 0022 and arduino 0018 but they give me this menssage: 

Binary sketch size: 3984 bytes (of a 14336 byte maximum)


avrdude: stk500_getsync(): not in sync: resp=0x81

avrdude: failed to write flash memory, rc=-1

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x80


The board is well selected in the arduino program, the port com too.


What can I do??
