I have Jetson Nano 2gb with camera imx 477 and it can’t recognize the camera.
Command:
gst-launch-1.0 nvarguscamerasrc sensor_mode=0 ! ‘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

Result:

Please help me. I have tried everything at this point. Thank you.

hello AlexLee44867,

may I know which JetPack release you’re using?
had you use the Jetson-IO to update device tree overlay for loading IMX477 camera driver?
please configure [Jetson Nano CSI Connector] to select overlay file.
