Installed the last img of ubuntu on khadas, then plugged in the camera (with the correct way and in correct spot), but it doesn’t even see it. Guvcview can’t find it, and there are no video50. It works with vim3, at list in Guvcview.
I checked on my side with a fresh installation of latest image with oowow, it works and I can use gstreamer to record a video from it.
