Still needing C5 SPI Enabling

It’s a year on from my first ask if anyone can help with enabling an Ordoid C5’s SPI so I can use Hyperion.

I have tried what little information I can find, but nothing works.

Tried getting things to work on my Odroid N2, at least SPI could be enabled through the CoreElec configuration under Kodi, but it was unstable and a known issue, so I invested in a C5 :frowning:

Please can someone help me figure this out?

I just use a €5 Arduino UNO with USB as a SPI converter with adalight firmware.

It just works for any Hyperion-ng device, not only with SPI interface (what is a limited number available).
