I'm using a MacBook Pro with 10.13.6, an Official Arduino Uno Board and Arduino 1.8.13 IDE.
I'm having troubles uploading code to the Arduino Board. I have 5 ports available:
I'm not sure if any oh these ports is the correct one but I've already tried all of them and I keep getting errors like: "
avrdude: ser_open(): can't open device "/dev/cu.-AvneraSPPPort": Resource busy"
Some weeks ago I was trying Arduino on the same computer and all went good but right now I can't get it to work, however I don't remember wich port was selected.
In the IDE the board I have selected is "Arduino Uno" and as Programmer option I have "AVRISP mkll".
Does anyone know how to solve this?
