I'm new in this forum...i switched from Windows to Mac (Macbook Pro with 10.8.2 OS X) some weeks ago and i'm having problems setting up my arduino board. I got an Arduino UNO with ATmega328 but i can't upload sketchs to my board...
First problem is that i can't find "Uno" on Tools>Board (i'm using the latest software) and i'm using instead "Arduino Duemilanove or Nano w/ATmega328. My arduino is on with the green and orange LEDs but i just can't upload anything. In Tools>Serial Port i selected /dev/tty.usbmodem1411 and when i try to upload something the orange LED and rx LED blink but nothing comes after...i got this message when trying to upload the Blink sketch:
Binary sketch size: 1008 bytes (of a 30720 byte maximum) avrdude: stk500_recv(): programmer is not responding avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xe0
Thank you for helping me Greetings!
