Just got my HP4 square this eve, unpacked it read everything, ok so there was nothing but the receipt…
Got out a RPI3B+ with OS 05/27/20
plugged in the header extender, ran the HW setup, shut down, installed the HP onto the header extender, fired it up.
Got a rainbow on both the HP and my 7" HDMI display, then 1/2 the HP went plack the other 1/2 looked like it had “rainbow scratches” running down the screen, SO i THOUGHT maybe the installer didnt finish.
Ran the one line installer and it seemed to install, but ended on a message sayng “Can not continue unsupported hardware”
The ONLY other item plugged in aside fomr the traditional mouse keyboard etc is my new HQ camera
now I could unplug that, but since the goal is to extend THIS project
which has the HiQ and the HP it would be kind of pointless.
anyone have some good suggestions?
