I did manual build a nightly Amlogic-ng-dv.arm CoreELEC-20.3.
So you can test it on one of the two devices. FEL may work, may not, not sure.
When it works don’t try to seek! It’s for sure not working and you will need to stop/start the video again.
FEL does not work yet on Amlogic-ne.
It’s preferred to make a new install with this image instead update as it’s now Kodi Nexus and not Kodi Omega anymore:
Happy testing!
