Hi
I connected IMX415 camera sensor in Jetson nano and done device tree and driver configuration.I was able to get the v4lt-tools based raw image capture from the sensor. So this means that the device tree configuration and the video path is working. I am getting the kernel log as the “imx415 detected” as well as the /dev/video0 node.But when I tried to fetch video from camera using gstreamer pipeline it is throwing an error:no cameras available.
Pipeline used and error log is mentioned below.
“gst-launch-1.0 nvarguscamerasrc sensor-id=0! ‘video/x-raw(memory:NVMM), width=(int)3840, height=(int)2160, framerate=16/1’ ! nvvidconv flip-method=0 ! ‘video/x-raw, format=(string)I420’ ! xvimagesink-e”
Error Log :

Setting pipeline to PAUSED …
Pipeline is live and does not need PREROLL …

Please help me.
Thanks in advance
It could be the tegra-camera-platform context of the device tree have problem cause “No cameras available”
And have you verify the “v4l2-ctl --stream-mmap --stream-count=100 -d /dev/video0” to confirm the sensor driver?
Hi
Thanks for your reply.I tried with the v4l2-ctl --stream-mmap --stream-count=100 -d /dev/video0
The log I am getting is given below

Could you please help me?
The devname is incorrect. The bus# should be 6 instead of 30
devname = “imx415 30-001a”
Thank you so much .I changed the devname and it is working fine now.
