Hi everybody, I'm using an Arduino uno on a Macbook Pro 5,1 with OSX 10.5.8. I'm new to Arduino, I'm using the "blink" sketch from examples to follow some tutorials but I'm always getting the same message
avrdude: stk500_recv(): programmer is not responding
This must be something with my software because I've tried different perfectly working Arduino Uno boards and I always get the same result. It works perfectly on the same Macbook Pro on Windows Xp under Bootcamp.
I've read the troubleshooting guide and previous similar topics but I cannot find a solution. I'm pretty desperate because I want to use my board under OSX but It's impossible :( Any help is WELL appreciated This is the verbose output during upload:
