Hi all,

The FSF listing has Raspberry Pi's as *fatally* flawed because they have
a propietary boot blob run by the VideoCore processor (as i have seen
building Devuan for Rpi2):

I've been reading in Internet and now i'm more informed and more
confused. It's not a single board computer, but the Penguin Pocket Wee GNU:

https://www.thinkpenguin.com/gnu-linux/penguin-pocket-wee-gnu-linux-desktop

from Think Penguin is very small and fully supports libre software.

Al the same time, i'm currently looking at the following single-board:

https://www.olimex.com/Products/OLinuXino/open-source-hardware

and the operating system based on Debian:

http://www.armbian.com/olimex-lime-2/

which i can't really grasp if is fully Free Software/Hardware or blobed
down.

I just downloaded Armbian and there is an archive with the GPL licence.
So, the software is released under GPL, but i guess that the hardware of
this single-board rapes the licence in any way, being the required
software Open Source rather than Free Software.

Cheers,

Aitor.
