EDIT: As of the latest nightly, CE-NG should now boot on ATV14 s905x4 devices.
Currently CE-NG doesn’t boot on the ATV14 s905x4 devices, only CE-NO works. CE-NO doesn’t support DV FEL.
ATV14 is still very new, and there is hope that CE-NG can be made to boot on ATV14 boxes, but this will take patience.
