No /dev/video0 folder

Hi Guys,

I’m using the TX2 with Avermedias EX731AAN1 carrier board and CN311-H HDMI input m.2 card. It’s a great small board and I’m currently in the process of trying to get the hdmi input to work. I’ve gotten a linux driver from Avermedia and I have installed this. However it does not seem to show up as a video device.

When I do “v4l2-ctl --list-devices” I get a "failed to open /dev/video0: no such file or directory?
This folder does indeed not exist in my folder structure.

How do I tackle this problem? Should I just create this folder? or should it be created automatically?

kind regards,


/dev/video0 will be created when a v4l2 driver is loaded. You should not create the device file manually.

Based upon your description it seems that you camera driver is not loaded or is failing to load. Run dmesg to look for clues as to why this might be.
