Hello!
I have just gotten my genuino uno and im trying to upload a sketch to the device. I get some error messages and i dont really know why.
I have tryed looking for awsers but dont really find any thing. It says in the set up that the serial port should be something like /dev/tty.usbmodem but i can only find (as you can see on the picture) /dev/cu.usbmodem1421.
Could this be the problem and how do i fix that?
I think that's the right port.
Does the loopback test work? Try that (see instructions in sticky thread at top of installation and troubleshooting section).
/dev/cu.usbmodem1421
You will find both cu.usbmodem1421 and tty.usbmodem1421 in the /dev directory when your Genuino is plugged in. As far as I can tell they behave identically. The IDE used to show both under Tools->Port but in recent version has chosen to show only the 'cu.' version.
