I’ve tried to plug my Arduino UNO board to my Macbook Pro (using OS X Lion 10.7.5) for the first time (I’ve used it in a Windows environment previously and it did work) and I get an error uploading.
First of all I’ve chosen Arduino UNO as board and dev/tty.usbmodemfa131 as Serial Port, when I try to upload the blink example and I get the following error (while compiling both TX and RX green leds blink):
avrdude: stk500_recv(): programmer is not responding
processing.app.debug.RunnerException: Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Please let me know if you have any idea about this problem and how to solve it. I don’t have a PC, only my Mac and I need to make it work!
