Lightpack on Pi3 with Hyperion – screen flickers

Posted on Author Kodi Community Forum - All Forums

Hi,

Any users of the original Lightpack hardware on Pi2/3 who had jumped the Krypton bandwagon?

Can’t seem to get mine to set up properly, very erratic behaviour is observed. It worked absolutely flawlessly on Jarvis (using the same config), albeit the colours are dull compared to what Prismatic software can output, but that’s OK. What I’m seeing on Krypton (LibreELEC 8.0.1) is that you could play something and it would kick on the LEDs OK for a while, but then it starts glitching and turning the screen off to a black image and going back to whatever was on the screen. Sometimes this flickering gets to a point of not being able to use the kodi menus at all.

The add-on was installed and configured via HyperCon, the build is the latest for the Pi I believe.

Code:
LibreELEC:~ # cat /storage/logfiles/hyperion.log | head -4
Hyperion Ambilight Deamon (464)
        Version   : V1.03.2 (brindosch-99d9396/d3713a8-1469452981
        Build Time: Jul 25 2016 06:54:40
INFO: Selected configuration file: /storage/.config/hyperion.config.json

Initialises correctly and plays the knight rider animation just fine.

Code:
LEDDEVICE INFO: configuration:
{
        "colorOrder" : "rgb",
        "name" : "PiCon",
        "output" : "",
        "type" : "lightpack"
}

But then every screen flash to black is accompanied by the following in the log:

Anyone with similar issues out there or perhaps was facing these and had them addressed?
Thanks in advance.
