We are adding features and making updates on a regular basis. You can keep track of what's happening on the Flybrix GitHub Page. 

This page will help you update the firmware on your flightboard using the simplest method available. Follow the steps below!

Step 1: Install the Teensy Loader Application

You need to download a small program to download firmware from your computer to your flightboard. Follow the instructions on the Teensy Loader Download Page that correspond to your operating system.

Please note that you only need to install the Teensy Loader application. You don't need to download or install the "blinking firmware" examples from the Teensy webpage.

Step 2: Connect your flightboard to your computer

Attach your flightboard to an available USB port on your computer using the cable from your kit, and plug in a charged battery.

Step 3: Download the latest Flybrix firmware HEX file to your computer

Visit the Flybrix Firmware Releases Page on GitHub. Click to download the HEX file from the latest release.

Step 4: Open the firmware HEX file in the Teensy Loader Application

Launch the Teensy Loader Application and select "Open HEX File" from the "File" menu.

Open the hex file you downloaded earlier in Step 3. (Please note that the filenames you see in these esample images may not exactly match the name of the file you downloaded since the tutorial images might be out of date. You will see something like "flybrix-firmware-a.b.c.hex" where a.b.c is the version code for the latest release file you downloaded.)

Step 5: Press the PROGRAM button on your flightboard

You will find the PROGRAM button near the USB port on the top side of your flightboard.

Step 6: Click the "Program" menu bar buttom in the Teensy Loader Application

You should see a progress bar as the firmware is copied to the flightboard.

The firmware should download with no error messages.

Step 7: Click the "Reboot" menu bar buttom in the Teensy Loader Application

Your flightboard will reboot with the new firmware.

Congratulations! Your firmware is now up to date!

To confirm that you have installed the latest firmware, unplug and replug your battery and observe the LED pattern when the board reboots. Version 1.5.0 shows one red LED and one purple LED as seen below.

*  If you happen to get an error message that states the hex file is too large,  you may have a faulty USB cable.
