Trying to use the NOIR raspberry pi camera with my jetson nano

Do you have a monitor connected to Jetson or are running headless ?

If you have a local display, be sure that no other process is using camera. Suggest to retry after a fresh boot.
Be sure you have a /dev/video0 node created by the IMX219 driver. If not, the camera has failed to be probed by driver.

If running headless, nvoverlaysink wouldn’t work.
You would connect from host to Jetson with ssh -X and in Jetson use:

gst-launch-1.0 nvarguscamerasrc ! nvvidconv ! xvimagesink
