Is the problem with rpi-2 booting with 7.0.0-image known about?
This shows up for me when using a rpi-2 with a HiFiBerry-digi overlay(dtoverlay=hifiberry-digi), in which the hifiberry evice is only seen on the first boot, on the secound boot the overlay directory content has been deleted! Then on the neat reboot the overlay directory itself is gone!!
If not known about I can post more info, otherwise does anyone have a work arround, I here others may have worked arround by installing an OpenElec image then after configuring it (so rebooting a few times), using the upgrade 7.0.0.tar file to update I have not confirmed this yet.
