There is a known bug in this image that causes stuttering, it is for testing purposes only.

Pre-Release Notes:
This image uses the FPVue project rather than gstreamer to display the video. It includes an OSD as well as DVR video recording. (OSD is NOT recorded, only displayed to the screen)
On first boot, the stream will not start to give the user the ability to set up the system. Please perform the following steps.

  • Step 1 - Flash the image to either your onboard emmc or a micro SD card.
  • Step 2 - Connect a screen and a wired keyboard to your radxa (you may need a usb-a to usb-c adapter or hub) and boot the system.
  • Step 3 - The system should boot to a CLI. Login as either radxa/radxa or root/root (I personally use the radxa user but some prefer using the root account)
  • Step 4 - cd /home/radxa/scripts and then run ./resizefs.sh to repartition and resize your filesystem. Ignore all the red text and let the script finish.
  • Step 5 - Use the onboard wifi to connect to your home network: while in the scripts folder, run the wifi-connect.sh script with your home network name and password as follows: ./wifi-connect.sh NetworkName NetworkPassword. Replace NetworkName and NetworkPassword with your home network credentials. To check your connection after, run nmcli and your wlan1 connection should be green. Make a note of your ip address. We will need this to ssh into the system later.
  • Step 6 - Set your desired screen resolution and refresh rate in the screen-mode file. sudo nano /home/radxa/scripts/screen-mode and change to your desired specifications. Format is WxH@fps -- Common values would be 1920x1080@60, 1920x1080@120. 1280x720@60, 1280x720@120
  • Step 7 - Set your WFB-ng channel in /etc/wifibroadcast.cfg and transfer your gs.key to /etc
  • Step 8 - Shutdown the system, disconnect the keyboard, and connect your wifi card. Boot the system and SSH from a separate computer.
  • Step 9 - Test the system. Run wfb-cli gs and plug in your camera. Make sure you are properly getting video and telemetry packets. Hit CTRL-C to exit the wfb-cli. Run sudo systemctl start openipc.service and the display connected to the radxa should change to your video feed with OSD. Press your DVR button. The stream should stop and a new stream being recorded should start. Press the dvr button again to stop the saving stream and go back to the display stream. Confirm there is a .ts video file in home/radxa/Videos. Run sudo systemctl stop openipc.service to stop testing.
  • Step 10 - Last and final step. Once you have confirmed the system is working and you have set your desired settings, run sudo systemctl enable openipc.service to have the stream begin on boot.

This is a prebuilt image for the Radxa Zero 3w to stream OpenIPC video. Simply setup your keys and desired channel, give the system a reboot, and after the stream will begin automatically on plug-in.

How to flash the image to your onboard emmc

On first boot, connect a keyboard and enter a terminal with CTRL+ALT+F1 -- login is root/root (user/password is radxa/radxa)

cd to the scripts folder: cd /home/radxa/scripts

Run ./resizefs.sh to repartition and resize your filesystem. Ignore all the red text and let the script finish.

Run wfb_keygen (located in your path) and transfer the keys. Run sudo cp gs.key /etc to transfer your gs.key to the groundstation's /etc directory. To transfer the drone.key file, connect your camera and radxa to your home network, then run scp drone.key [email protected]:/etc and replace x.x.x.x with your camera's local ip address. (You will need to set up your network accordingly.)

Stock settings will set the display to 1920x1080@60fps. You will want to change this behavior in the screen-mode file in the scripts folder found in your home directory. -- sudo nano /home/radxa/scripts/screen-mode
e.g. for HDZ goggles -- change to 1280x720@100

You can use the handy wifi-connect.sh script found in the scripts folder in the radxa home directory. Run the script with your home network name and password as follows: ./wifi-connect.sh NetworkName NetworkPassword. Replace NetworkName and NetworkPassword with your home network credentials.

You can also manually setup the onboard wifi for SSH connectivity. (udev rules and networkmanager are already configured in this image, you only need to execute the nmcli commands)

This image includes DVR functionality; It requires a push button to be installed to the gpio header between physical pins 25 and 27 like so:

radxagpio

To record DVR, push the button once. The preview stream will end and the the recording stream will start; DVR will begin recording. When finished, push the button once to stop the recording and save the file. The recording stream will end and the preview stream will return.

DVR is saved to the Videos folder in your home directory. DVR can be accessed either at /home/radxa/Videos or via a media server. Connect your groundstation to your home network and it can be accessed via a web browser at x.x.x.x:8080 -- replace x.x.x.x with your groundstation's local ip address.
