Hello, I’ve got a A-Star 32U4 Micro and it’s stopped accepting uploads from Arduino IDE 1.6.5. It was originally working, i loaded some sketches after it first arrived. The error I get is: “can’t open device “/dev/cu.Bluetooth-Modem”: Resource busy” … I’m on OS X.
So I tried following along with this, under section 10.1:
I’ve successfully attached the reset button, and I see the orange light flashing after I push button twice. However I never get the new serial port that’s referred to multiple times in each of the paths for fixing it. I look either in the arduino IDE or on the terminal under /dev/ and I never see a new device pop up, nor can I get the Arduino IDE into a state where no port is selected, or the menu is greyed out as the directions say.
Any ideas?
