I've managed to build libreelec 9.2 with kodi 18.5 for orange pi pc plus (h3) 2 weeks ago.
At testing i found out it had problems maybe with drm (randomly green flashes till complete green lockup at playback) and random system freezes. so i'm back to nightly with kodi-git-18.3 from sometime in july.
i'll now try current master with kodi 18.5. maybe it run's better. for shure i'll share the images if it runs fine.
