Hi I have tried to upload sketches on my Arduino Due many times, but this error appears. I think that the problem must be because in the option "Tools>Boards" is selected "Arduino Mega (ATmega1280)" but I haven´t found "Arduino Due" on the List, and I don´t know why it isn´t on it.

error: avrdude: stk500_getsync(): not in sync: resp=0x00

you should download the - Arduino 1.5.2 - version on the download page - it is the second one NOT the top download
