Thanks for the response. I am working with zhuda on this. Here’s some additional information for you:
We have actually tried 3 Nano Developer kits, all with JetPack 4.6 installed and on one of them the camera works well with v4l2-ctl, but on the other two we get the errors mentioned by zhuda most of the time. We have several cables and RaspI HQ cameras and have tried many combinations with our boards. We have also cloned the SD card to rule out any differences in the installation status.
It appears as if JetPack 4.6 solves the problem for other users (see Nano 2GB + Raspi HQ Cam nvarguscamerasrc working but not v4l2-ctl - #19 by JerryChang) but, at least for us, it appears to be dependent on the particular DevKit hardware being used.
