Update (25-Apr-2016): Check out the video on Flite Test. If their instructions don't work, feel free to try what I did listed below.
Here's a short guide for anyone using a Mac to install the latest Cleanflight firmware in a new Naze32 rev6 flight controller. At the time of this writing, Cleanflight Configurator is version 1.1.0 and the Naze32 firmware is version 1.11.0.
Solder a bridge across the two pads marked "boot" on the board. See Figure 1. I did this simply using a bare wire; very easy to remove later.

Do not attach the Naze32 to your Mac. Be patient.
Download and install the USB to UART Bridge VCP Driver.
Download and install the Cleanflight Configurator at the Google Play store.
Restart your Mac.
Open the Cleanflight Configurator app in Chrome.
Do not make any changes to the Welcome screen. Switch to the Firmware Flasher by clicking the tab in the sidebar.
Figure 2. Switch to Firmware Flasher.
Choose the most recent, stable NAZE firmware from the drop down menu.
Switch on the options for "No reboot sequence", "Flash on connect", and "Full chip erase."
At the bottom of the window, click "Load Firmware [Online]".
Figure 3. Options in Configurator.
Connect a USB cable to the Mac and then the Naze32. The flight controller should only illuminate the blue LED.
Click "Connect" at the top of the window. The firmware will now transfer to your Naze32. An orange progress bar appears at the top of the window (sorry; no screen capture). LEDs on the Naze32 will not flash to indicate a file transfer. Instead, expect the LED to remain a solid blue.
Once transfer is complete (requires less than a minute), close Cleanflight Configurator and then disconnect the Naze32 from your Mac.
Remove solder bridge that connected boot pads in the first step. Desoldering braid works well for these small pads.
Re-open Cleanflight Configurator.
Connect a USB cable to the Mac and then the Naze32 rev6 board. The board should illuminate blue, gree, and red LEDs. Once the Mac has recognized the Naze32 (within a few seconds), the red LED will stop flashing and you will see a solid blue LED and a flashing green LED.
Click "Connect" at the top of the window and have access to the many configuration screens for the Naze32.
Since your Naze32 now has Cleanflight installed, you will not need to solder a bridge again in the future. If you choose to later install a new version of the firmware, do not choose "No reboot sequence" from the Firmware Flasher.
Good luck!
Before viewing this post, I did connect my Naze32 to my mac, without any drivers installed, but didn't attempt to flash it. And now I can't flash it at all, even following all of your steps. Did I shoot myself in the foot by connecting it earlier? Thank you for any help!
ReplyDeleteYou may also want to try connect to your board using Baseflight. If it works, then you'll know that it's simply a driver issue and not the board. Good luck!
