I have a Raspberry Pi Zero W.
I installed latest version of Raspbian stretch (2018-10-09) on it and I have installed Tvheadend 4.2.4 to make work the tv hat.
The problem is that the adaptors folder in Tvheadend is empty (missing drivers or something similar?).
The same procedure works on a Raspberry pi 3.
Where am I wrong? Thank you.
