Updating the Elios 2 Camera Firmware
If updating the Avionics Firmware does not work
Depending on the current Avionics version loaded into you Elios 2 drone the update process is different. Please check your current version and follow the corresponding process.
Also note that the camera firmware must not be updated if it is already at the latest version.
Connect a PC to you drone using via the USB cable, or, remove the Payload LOG SD card.
Download and copy the new Avionics firmware binary file (ELIOS2_Vxxxxx.BIN) to the root of the Payload LOG SD card.
Power up the drone with a fully charged battery. The update will not start if the battery voltage is too low.
The firmware process will begin and the 4 arm sensors LED will blink quickly, in a yellowish colour
The drone may reboot several times, you will hear the start up chime, do not unplug the battery until the update process is completed. This can take up to 5 minutes
When the arms LEDs blink one after the other and slower in a yellowish colour, the update is done, you can unplug the battery.
Plug back the battery and connect the GCS, go to Cockpit 'About' tab and verify the avionics firmware version.
