Upload Debug

This is the error I receive while trying to upload to the Arduino. I have installed FTDI drivers for mac. (http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_18.dmg)

The board is part of a quadcopter: https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=50460

The processor is an Atmel 328P. Do I have the correct drivers?

What else could be the issue?

  • You shouldn't need to load any drivers for your Mac; it should (mine does) recognize your FTDI USB device the moment you plug it in. – JRobert Sep 6 '14 at 0:07

You may have wrong port: /dev/tty.usbserial-A9007LXq works with Duemilanove on my Mac.

  • You can check this by opening a terminal and typing in ls/dev/tty. and then hitting tab. It should tell you all the open ports – Treesrule14 Sep 5 '14 at 14:05
