imx219-160IR 8MP is not connected to jetson nano

I put some code to Terminal.
DISPLAY=:0.0 gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM), width=3280, height=2464, format=(string)NV12, framerate=(fraction)20/1’ ! nvoverlaysink -e

And then, I got this sentence.
Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:645 No cameras available

I want to know what is 645 that is error code.
My jetson doesn’t recognize that camera. So I can’t do any more. Help me plz…

This is jetson TX2 forum. Is your issue on jetson nano or TX2?
