[Coco] Drivewire on an original Raspberry Pi

[Walter ZAMBOTTI]

Just to be clear.

I haven't got this working on a PI.

I'm using Ubuntu 21.10 on a ODROID N2 (ARM based and 64bit OS).

I have the armhf DEBs to that should get it going but...

I don't have a PI to test that.

Theoretically it should work on a PI, but those sound like famous last 
words!
