NVIDIA Camera virtual enumerator not found in proc device-tree error at TX1 r28.2

I run command “camera_jpeg_capture”, find the error “NVIDIA Camera virtual enumerator not found in proc device-tree”

Hi sensor_test,

Have you followed the suggestion in [url]https://devtalk.nvidia.com/default/topic/1035461/jetson-tx1/error-is-run-quot-nvgstcapture-1-0-quot-at-jetson-tx1-r28-2-/post/5260209/#5260209[/url] to get your device tree working?

Please update the status back to origin thread first.

Thanks

Hello kayccc,

I can use v4l2-ctl capture a picture.

What define string I must add to dtsi file?

nvidia@tegra-ubuntu:~/tegra_multimedia_api$ ls /dev/video0*
/dev/video0
nvidia@tegra-ubuntu:~/tegra_multimedia_api$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100
