I am using dragon Q6A with 8M219. The camera module is detected but when I try to display it didn't show anything but a blank white screen.pls help me if you know the solution. It would really really helpful🙏🏻

[Milir-Radxa]

Are there any log messages when you run the command to start the camera? You could shut down the system, reinstall the camera, and then try following the tutorial again.

The camera issue has been resolved on our side. We've updated the libcamera packages, but the documentation isn't ready yet — it will be included in the next release. Thanks for your patience.

Hello,
I face the same issue too. (With Radxa Q6A with IMX 219 8M camera)
Only a black screen appears even after following the libcamera zip version.
Expecting you to reply soon.

You mentioned earlier that the fault is on the software and you are sorting that out. You also shared the zip files and code to follow which is not working for us. So it would be nice if you inform us when the updated software would release, else we expect you to notice us if you are working on this issue and how to sort out things.

[chenchongbiao]

Let me try to reproduce the issue on my side first.

[chenchongbiao]

1. Use the official system image
   Make sure you're running the official RadxaOS image:
   Download: https://github.com/radxa-build/radxa-dragon-q6a/releases/download/rsdk-r2/radxa-dragon-q6a_noble_gnome_r2.output_512.img.xz

2. Install the updated libcamera packages

Download and install the pre-built debs
https://github.com/chenchongbiao/libcamera/actions/runs/27256200300/artifacts/7527665865

unzip libcamera.zip
sudo apt update
sudo apt install ./*.deb
sudo apt install -y gstreamer1.0-tools gstreamer1.0-plugins-base

3. Enable the camera overlay via rsetup

sudo rsetup

Navigate to: Overlays → Enable camera2 (for CAM2 slot) or camera3 (for CAM3 slot).

Check the board markings to confirm which slot your camera is connected to. The silkscreen labels on the board are CAM2 and CAM3.

Do NOT enable both camera2 and camera3 overlays at the same time — they will conflict and block each other (CSID arbitration issue). Only enable the one you are actually using.

After enabling the overlay, reboot:

sudo reboot

4. If hardware encoder causes reboot, apply the fix
   See: https://docs.radxa.com/en/dragon/q6a/faq#why-does-q6a-reboot-immediately-when-using-the-hardware-encoder

5. Verify the camera
   Hardware-encoded recording examples:

H.264 1080p
gst-launch-1.0 -e libcamerasrc \
        ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 \
        ! v4l2h264enc ! h264parse ! mp4mux \
        ! filesink location=/tmp/camera-h264.mp4
    
H.265 1080p
gst-launch-1.0 -e libcamerasrc \
        ! videoconvert ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 \
        ! v4l2h265enc ! h265parse ! mp4mux \
        ! filesink location=/tmp/camera-h265.mp4

If anyone gets the camera working after applying the radxa-docs but then runs into a pink/magenta color cast, or wants to run both IMX219 cameras simultaneously (fails with "msm_csid0 in use"), I documented the root causes and a fix for both here:

🔗 https://github.com/DuyLeTran/radxa-q6a-dual-imx219-libcamera-fix

[tangzz-radxa]

Thanks for sharing your root-cause analysis and the fix with the community — this is very helpful for other Dragon Q6A + 8M 219 users.

For anyone following this thread: Radxa has also updated the official libcamera packages (https://github.com/radxa-pkg/libcamera) to address the camera issues on Dragon Q6A, and the updated documentation will be included in the next release.
