2. Enable Camera Overlay
2.1 Ubuntu22.04 image to enable camera overlayβ
- Use nano to open the /boot/firmware/ubuntuEnv.txt file:
sudo nano /boot/firmware/ubuntuEnv.txt
- Find the "overlays=" keyword in the file, and add the following:
overlays=armsom-sige7-camera-imx415-4k
Shortcut keys: Ctrl + S to save, Ctrl + X to exit
After editing and saving, restart the device to change the Overlays settings to support the camera.
2.2 Armbian image to enable camera overlayβ
- Use nano to open the /boot/armbianEnv.txt file:
sudo nano /boot/armbianEnv.txt
- Find or add the "overlays=" keyword in the file.
overlays=armsom-sige7-camera-imx415-4k
Shortcut keys: Ctrl + S to save, Ctrl + X to exit
After editing and saving, restart the device to change the Overlays settings to support the camera.
3. Use the Camera
You can download cheese and then use the camera with the following commands:β
armsom@armsom: sudo apt update
armsom@armsom: sudo apt install cheese
armsom@armsom: ./cheese
Or you can also preview the camera using terminal commands:β
