Look at the forum's sticky posts for a how to do a loop-back test. Note this might have indicated a problem with the 8u2. In your previous case, multiple copies of avrdude were stuck for some reason. (just running lsof would list every open file-keep in mind everything in an UNIX operating system gets a file handle, even devices.) When you get the "Serial port in Use" error, the combination of lsof piped to grep lets you see what processes has the specific serial port open. Lsof stands for "list of open files." grep takes results returned and filters by the keyword. The grep usbmodem isn't returned with anything either even if the UNO is plugged in and blinking away. chmod would only return something if it failed. mkdir tries to create the directory, chmod sets the permissions. The mkdir command is returned with a "mkdir: /var/lock: File exists"īoth makes sense.

I'm asked for password but the terminal doesn't return with anything.

I would be very greatful if someone out there has any thoughts on this… I’m going to reboot the computer and see if I get a different result in the terminal. What can this be if I have nothing plugged into the usb ports of the computer? I tried running this in the terminal both with the UNO plugged and un-plugged and the result is the same. I have no idea what this means, but I’m guessing it looks wrong.

The terminal returned this after I typed in the pw: mkdir: /var/lock: File exists.

I went through the steps suggested by James and here is what I got: Thanks for the replies! Much appreciated!įirstly, I had selected the correct board and serial port. I've found a few posts describing similar problems but most of them are quite old and none of the info there has been helpful in my case. In "Networks" a new network was made but is constantly "disconnected" (and can't be connected). I did NOT get a pop up regarding a new modem when I plugged it into the computer. I followed the the installation instructions to the letter (tried 3 times already). When I plug it into the computer the green "on" light comes on and the L led blinks orange. I have no other programs running, nothing plugged to the board and nothing plugged to other usb ports of the computer. Here is some additional info that may or may not be relevant:

In short, I get this message when I try to upload to the UNO: Serial port '/dev/tty.usbmodem411' already in use I just received my Arduino UNO board in the mail (my first ever, so I'm a complete virgin) and have spent the whole day trying to get it working but with no luck.
