Add 'dtparam=i2c=on' and 'dtoverlay=imx219' to the config.txt file on the
first partition, reboot and (dependent on your configuration) load the
module via 'modprobe imx219' (or re-build your buildroot image with
'/dev management' set to Dynamic mdev or eudev which will enable the
udev autoload magic of the kernel modules)...

Regards,
Peter
