Sorry guys i was a bit busy these days...
I have seen a post about Pi not really confirmed so i will answer, if there is other post to answer just tell me i have maybe not seen it.
Is there a Cbx wallet for rpi 3?
Raspberry Pi support is slated for within the next month or so I think, presumably RPi 3 will be in it or included, but Alex will have to confirm.
Not sure what the problem might be m33. If you have rebooted the client and it staked then I would suggest leaving it for a while again to see what happens. If it still won't stake then of course post here again and one of the devs will look into it.
A wallet for RPi should be done for next middle/end of next month. It will work on all RPi
