Hi,
We are using SerDes cameras from Appropho and FE-PI AUDIO Z V2 audio modules on Jetson Nano.
First we intall the cameras and after we enable the audio board with /opt/nvidia/jetson-io/jetson-io.py
After this we cannot access the cameras any more.
We try with the following gstreamer comand
$ gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=0 gainrange=“1 16” ispdigitalgainrange=“1 1” ! ‘video/x-raw(memory:NVMM), width=(int)1948, height=(int)1096, format=(string)NV12, framerate=(fraction)30/1’ ! nvvidconv ! fpsdisplaysink video-sink=xvimagesink -e
GST_ARGUS: NvArgusCameraSrc: Setting Gain Range : 1 16
GST_ARGUS: NvArgusCameraSrc: Setting ISP Digital Gain Range : 1 1
Setting pipeline to PAUSED …

But the cameras are visible under:

We tried this on 4.4.1 and 4.5.1 releases but the result is the same. Its not even needed to attach the FE-PI to the Nano after

Do you have any idea what can go wrong?
Thanks you!
