Hello,
I’m trying to connect tiscamera(The imaging source) to my verdin imx8 plus platform running yocto reference image. I built the image using yocto layers.

I have copied arm libraries to the /usr/lib and /usr/bin folders and when running tcam-ctrl utility to list available cameras it won’t show anything, if there is something that have been tried, please share

Hello,

To connect and use a Tiscamera with your Verdin iMX8 Plus running a Yocto reference image, you can follow these steps to troubleshoot the issue:

  1. Verify Camera Compatibility: Ensure that your Tiscamera is compatible with the Verdin iMX8 Plus and that the necessary drivers are included in your Yocto build. The camera should be recognized as a Video4Linux2 (V4L2) device.

  2. Check Library Paths: Confirm that the ARM libraries you copied are in the correct directories (/usr/lib and /usr/bin). Make sure these libraries are compatible with your system architecture and that there are no missing dependencies.

  3. Use v4l2-ctl: Before using tcam-ctrl, try listing video devices with v4l2-ctl --list-devices. This command will show if the camera is recognized by the system. If the camera appears, it confirms that the kernel recognizes it as a V4L2 device.

  4. GStreamer Pipeline: Test the camera using a GStreamer pipeline. For example, you can use a command like gst-launch-1.0 v4l2src ! autovideosink to see if the camera can capture and display video.

  5. Check tcam-ctrl Utility: If tcam-ctrl is not listing the camera, ensure that it is correctly installed and that all its dependencies are met. Check for any error messages that might indicate what is missing or misconfigured.

  6. Device Tree Overlays: If your setup requires specific device tree overlays for camera support, ensure they are correctly applied. This might involve editing the /boot/overlays.txt file and rebooting the system.

  7. Kernel Logs: Check the kernel logs (dmesg) for any messages related to the camera when it is connected. This can provide clues if there are driver issues or hardware recognition problems.

By following these steps, you should be able to diagnose and potentially resolve the issue with the Tiscamera on your Verdin iMX8 Plus. I hope this helps!

Hello @gaurav!

Sorry for the late reply.

Can you share some more information about your setup?
Which layers are you using? Do you tried to build the reference multimedia image, or is it another one?

Best Regards,

Marcio
