Hello forums! I bought jetson nano 4GB which has model name P3450 and a IMX219-120 camera . I used opencv2 to start interacting with camera but it didn’t work. The error said that it cannot find camera by index.?
Does the sensor driver probe successfully?
Have a check with v4l2-ctl --list-devices. Also check the kernel message by " dmesg | grep -i imx219"
Thanks for your response !
I got this message when typing this line “v4l2-ctl --list-devices”
vi-output, imx219 8-0010 (platform:54080000.vi:4):
and here is the message I got from this command “dmesg | grep -i imx219”

Could you confirm if below command working well?
v4l2-ctl --stream-mmap--set-ctrl bypass_mode=0
Also what’s you command to launch camera? Have you try sensor-id=1?
No the command resulted in
v4l2-ctl: unrecognized option ‘–stream-mmap–set-ctrl’
Unknown argument ‘bypass_mode=0’
I used opencv to turn on camera as well as chess webcam booth.
It’s could be the command line not type correct.
I don’t think the bayer sensor(imx219) can support chess webcam.
Hi ! The command v4l2-ctl --stream-mmap --set-ctrl bypass_mode=0
gave me this message
“VIDIOC_REQBUFS: failed: Device or resource busy”
Some APP acquire the video# node.
Try reboot the system and try it first.
Jetson nano can detect my camera now but I cannot turn on camera. I followed CSI-Camera instruction.
This command " gst-launch-1.0 nvarguscamerasrc sensor_id=0" gave me
Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:551 Failed to create CameraProvider
I tried “python test.py” and it showed “can’t open camera by index”
It’s original system image? what’s the version?
Check the BSP version by
How about the sensor-id =1?
gst-launch-1.0 nvarguscamerasrc sensor-id=1 ! 'video/x-raw(memory:NVMM),format=NV12' ! nvvidconv ! xvimagesink sync=false
Any message from the launch console?
Does your Nano have two camera connector? Try to connect to another connector.
OK I will try it! Thanks for your quick response
