Stepping through the course “Getting Started with AI on Jetson Nano”, I started with Jetpack 4.2 but reinstalled with Jetpack 4.3.3 when the update came out.
I have a 8GB Nano with a Raspberry Pi V2 CSI camera and a USB Logitech C525 webcam.
When running the “Hello Camera” with the csi_camera.ipynb from the Jupyter notebook, the CSI camera is not detected.
ls /dev/video*
/dev/video0 /dev/video1
video0 is the CSI camera, video1 is a Logitech

Receive run-time error on the import CSICamera
Could not read image from camera
Camera works fine with g-streamer so it isn’t a hardware issue
gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=960, height=616’ ! nvvidconv ! nvegltransform ! nveglglessink -e
I have switched to using the USB camera and am able to continue the lab sucessfully, but I am curious why the Raspberry Pi CSI camera no longer works with Jetpack 4.4.1
