Hello.
Im trying to add UVC support to a ConnectCore6UL developement kit.
I followed this tutorial on making temporary changes to the kernel and included support for the UVC class. I touched absolutely nothing else, because, as you might have guessed, Im a complete noob when it comes to compiling kernels.
I then saved the changes, uploaded the zImage file as mentioned in the tutorials and rebooted the device.
Running ls /dev/video* now correctly displays the webcam.
However, wifi won’t load anymore.
