Updating IF800 Aircraft Firmware

This page is a guide for updating the firmware on an IF800.

This firmware is compatible with Herelink aircraft using Gremsy VIO, Sony LR1, Sentra cameras, and LIDAR payloads only. If you have any custom solutions, Micasense, PhaseOnes, A7R, A6500, SROC controllers, LRT models, etc, this update is not compatible. Please contact Customer Support for more info.

For safety, remove IF800 batteries and keep IF800 arms folded and propeller holders installed during upgrade process. Powering on the aircraft is not required for this update.

  1. Open Mission Planner on a PC.

  2. Connect a USB-C to USB-A cable between the aircraft's USB port and the PC's USB port.

  3. Connect to the vehicle using the MavLINK Com Port Connection.

  • Note: the COM number may change but always select the "MavLink" option.

  • Then, select Connect in the upper right corner.

  • If "MavLink" option is not available, choose "AUTO" and connect.

  1. Save your current parameters for your records

  • Click, Config

  • Select Full Parameter List

  • Save to File as “Pre-update_Params

  1. Check the Lua Scripts on your aircraft

  • Navigate to Config

  • Select, the MAVFtp tab

  • Then, double-click on APM to expand

  • Once the folder expands, double-click on scripts

  1. Ensure the following two Lua Scripts are on your vehicle:

    • IF800 script v1_0_flipped_front.lua

    • payload_1.lua OR payload_1_final.lua

    If the scripts do not match the above file names, you will need to download the correct scripts and install them on the aircraft. Delete the incorrect scripts by right clicking and selecting delete.

  2. The two correct scripts can be downloaded from the links below.

8. Drag and drop the needed script(s) from the computer's local drive into the script folder

  • IF800 script v1_0_flipped_front.lua

  • Payload_1.lua

9. Verify the Cube Firmware

  • Navigate to the Messages tab.

  • Select Disconnect to stop the Messages list from populating.

  • Scroll through the Messages list and locate the Cube Version for your aircraft (see screenshots below).

  • There is a different firmware file available depending on your airframe and Cube type. It is very important to download the correct cube software. The two options for the IF800 are as follows:

    • IF800 4.4.4: IF800 Airframe with a Blue Cube

    • IF800-CubeOrangePlus: IF800 Airframe with Orange+ Cube

IF800 Blue Cube

IF800 Orange Cube+

10. Download correct firmware file

Installing the wrong Cube firmware can cause vehicle instability, so be sure to check Cube version before installing firmware.

11. Ensure the USB cable is still connected to the aircraft and computer.

  1. Select Setup from the top menu

  • Select Install Firmware from the left side menu

  • Select Load Custom Firmware from the lower right menu.

DO NOT select a vehicle type, as this will reset your vehicle's parameters.

If you are receiving the warning below, you did not click disconnect inside mission planner. Do not upgrade the bootloader. Click NO, and then click disconnect in the top right hand side.

  1. Locate the previously downloaded firmware file on your PC and install the firmware

  • Wait for the firmware to update.

  • The progress bar will fill and a "Complete" message will pop up.

14. Once the updates are complete, unplug the USB cable.

15. Verify Accelerometer and Compass

  • Install a single aircraft battery. (This is an additional safety precaution, as the vehicle will not arm with a single battery.)

  • Turn on the GCS and aircraft.

  • Open the IGC App.

  • Select the IFT logo in the top left.

  • Select Vehicle Setup.

  • Select Summary.

  • Frame, Radio, and Sensors should all have a green circle next to them.

  • In the Frame window, ensure Frame Class is Quad, Frame Type is V, and Firmware Version is 4.5.6

In the event that one or more of the status circles is not green, do not attempt to recalibrate. Please contact IFT Customer Success before continuing, as there may be another issue that needs to be addressed.

  1. The firmware update and scripts install are now complete. Restart IGC and reboot the drone.

  • If your aircraft is paired with the Sony LR1, or Gremsy VIO, payload update next steps are below.
