Hi,
We have a camera based on the ov10640.
I’m using the d3-jetson-bsp-D3-RELEASE-5.0.0. I’ve followed everything in the release notes.
The v4l2-ctl “shows” streaming - but the argus_camera utility doesn’t show that the camera exists.
dev@ubuntu:~$ v4l2-ctl --stream-mmap -d 0
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.39 fps
<<<<<<<<<<<<<<<<<<<<^C
dev@ubuntu:~$ v4l2-ctl --stream-mmap -d 0
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 28.70 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<< 29.50 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 29.80 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 29.92 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps dev@ubuntu:~$ v4l2-ctl -D -d 0
Driver Info (not using libv4l2):
Driver name : tegra-video
Card type : vi-output, sc9732cam 2-0063
Bus info : platform:15c10000.vi:0
Driver version: 4.9.253
Capabilities : 0x84200001
Video Capture

Extended Pix Format

I’m not sure what to do about the isp file.
I put a sc9732cam.isp file (based on the ov10640.isp) into /var/nvidia/nvcam/settings on the AGX, but when I reboot, there are no d3_X_sc9732cam.isp links to the file.
I also placed the sc9732cam.isp file into /d3-jetson-bsp-D3-RELEASE-5.0.0/d3-jetson-util/target-overlay/var/nvidia/nvcam/settings/sc9732cam.isp and rebuilt the d3 dtb and image. Still no difference.
I even manually linked d3_3_sc9732cam.isp to point to sc9732cam.isp and rebooted - but still the argus_camera utility doesn’t find the camera.
Please help so that we can start seeing video with our proprietary device.
Thanks,
Mechi
Hi,
For clarification, do you use D3’s OV10640? Or you use your own OV10640? The package d3-jetson-bsp-D3-RELEASE-5.0.0 shall enable Xavier + D3’s OV10640 and it should work well.
We use the D3’s OV10640 cameras and see video with the argus_camera application. We used the drivers of the ov10640 to build the drivers for our camera.

do you have logs for reference? did the error report no camera available?
please also share device tree sources of tegra-camera-platform{} fields for checking.
Hello Jerry,
Thanks very much for answering.
A very improbable solution was all that was needed.
I erased from the Makefiles all of the compilations for the different D3 and Nvidia products that we don’t have.
The kernel Image is much smaller and video started streaming.
This may be a good first step for anyone experiencing similar problems.
Thanks again,
Mechi
