I don't know, which is why I'm wary of just making either change.
I know next to nothing about which cubox models there are nor what
features/rtcs they might each have. Does anyone have a cu-box with only
the SNVS driver they can try?
At the moment my inclination is to enable both drivers and see what
happens.
Ian.
