libcamera and libcamera-apps added to the armv* repos - note that piCore-13.1 is required.
Add the following to config.txt: to enable the camera: camera_auto_detect=0
dtoverlay=imx219
Load libcamera-apps and then: sudo chown tc:staff /dev/media*
sudo chown tc:staff /dev/dma_heap/*
Check things are OK with: libcamera-hello -n
libcamera-still -r -n -o test.jpg
* tested with an RPi3
* RPi camera v2.1 used - a different dtoverlay will be required for other cameras
* there is a fix for /dev/media permissions in tc git
