Hi @JerryChang,
I am using the latest Jetpack-6.2. I already read the link you suggesteda nd applied them but the problem is that the /dev/videoX is not created on my custom board. I would like you confirmation that using the device-tree overlay with the Jetson-IO tool is the only way to register a custom camera driver so that /dev/videoX is present and this could also be applied to a custom board instead of only developer kits as you said?
Thanks and best regards,
Khang
