Olimex has always been about producing community-friendly boards, not about the
software. Nevertheless, Olimex has been involved with the linux-sunxi community
from the early days and has always been very supportive, by providing developers
with hardware to work on, taking part in the community, etc.
What software they ship, or used to ship by default is IMHO a bit irrelevant.
They shipped whatever Allwinner provided but always supported community free
software effort. Also, when they started with Allwinner, mainline software
wasn't an option.

Huh? This is factually not correct. Olimex has released the PCB source designs
of a number of Allwinner boards. That's what those .brd and .sch files are at:
Better yet, the latest one (A64) was designed with KiCad, so those design
sources can even be handled with free software! This is an unprecedented
achievement that even the EOMA68 project has not reached (yet).
linuXino_Rev_A and open it up with KiCad if you wish to see for yourself!

Of course, I do agree that free mechanical designs are important and a great
thing to have, so I'm very happy that the EOMA laptop housing design is free.
But my focus here was about digital technology, not mechanical parts. This is
out of that scope.

I don't share that perspective. I think his contribution to freedom in digital
technology has been solid and significant. The devices he's producing show as

Of course, we all know that, but that's how you move forward! We can't just wait
for the situation to be magically resolved before considering producing hardware
with it, and staying away from it with a teen-feet-pole before. Simply because
no change will ensue of that. Olimex has the ability to create boards early-on,
that will encourage the community to work on this chip, and also create leverage
So it's really not about what the situation is right now, but about what it can
possibly become. Allwinner chips have *always* been a mess to deal with at
first, but efforts from companies like Olimex and the community made it possible
to have the kind of support we know today for chips like the A20.
Also bear in mind that you were able to get the EOMA68 together, with that level
of free software support, in part thanks to people like Tsvetan who put together
(free hardware) boards for the community to work on those chips and supported
their efforts early on, when the situation is indeed a mess.

Again, you're looking at the situation right now, which indeed matches what you
describe. However, I think Olimex sees a lot of potential in A64 and so do I.
Only time will tell whether it was a dead-end or not.

Frankly, I don't care that a device doesn't work with free software right now if
it has potential to be liberated eventually and if producing that device can
create the leverage to drive exactly that effort. This is what has always
happened with Allwinner chips.
But of course, Olimex and you are not in the same position. They can afford to
produce boards with chips that still have very early free software support. On
the other hand, you need something that has good free software support. One
comes after the other.
I'm really surprised that you don't see things this way and attack Olimex for
what level of support their latest products have *right now*.

From what I can see, the actual improvements (again, from the digital technology
side of things, so I'm not including the mechanical design) come down to not
including a Wi-Fi chip that requires proprietary software in a laptop design,
which is what had been lacking from the ARM Chromebooks. If you see anything
else, please state it clearly.
There are also rare occurences in your design, meaning that only few products
before (such as the ARM Chromebooks or the Novena) had reached that level of
support, such as: using a SoC that has few freedom flaws (GPU), having a free
software keyboard controller. We could also add free hardware design there (but
I'm still a bit confused about what the situation actually is and didn't take
the time to look it up properly).
If you feel like I'm missing something substantial, please let me know.

Again, everything you can do with modularization you could do by producing new
versions of boards. It solves the environmental problem and is convenient to
users, but has little to do with freedom in digital technology. If you have
actual specific point to counter those points (other than vague statements like
"part of a strategy"), I'd be happy to react to them.

So if we're talking about free hardware projects, then I'll agree that the
situation hasn't been that great. As far as I know, only Olimex, Novena and a
few others have been producing free hardware computers that work well with free
But again, I'm still confused about the hardware freedom situation of your
device. The most meaningful part is, of course, the EOMA68 board with the A20,
not the carriers (even though having them as free hardware is very nice).
On the other hand, the availability of boards that have components that work
well with free software have never been a problem, there's not discussion to

That's not what I'm saying. I'm saying that there are easy and nearly painless
ways to solve these problems, by using external ath9k_htc USB dongles. This fact
(and this fact only) reduces the presence of a Wi-Fi peripheral that requires a
non-free firmware to a minor annoyance.

Glad to hear it.

Well, I have been talking about the freedom situation in digital technology all
along, not commitment. I do agree that commitment such as the one displayed with
your project is a rare thing. And that is indeed groundbreaking (even though
projects like the Novena were here before), because that kind of intent is
clearly lacking from e.g. companies producing Chromebooks, so it rather feels
like we got lucky (or that people inside these companies care a lot, but it
doesn't reflect in the company's PR).
Commitment is important for the long run, so I'm really glad you're around. We
can't just rely on sheer luck to get devices that do well with free software
from mainstream manufacturers, even though we've had good luck a great number of
times already (and bad luck an astonishingly greater number of times, too).

I wouldn't include Olimex in that list, but I share your views on that.

Definitely, that's a (if not the only) reliable (but harder and perhaps more
dangerous) way to achieve progress for freedom in digital technology. Going with
luck has worked well in some areas (again, ARM Chromebooks), but we knows when
our luck will turn.
Even though this conversation may have taken a harsh tone at times and places, I
do believe we share the same views and only disagree on details (which fill up
most of our discussions here). I hope this is clear and this discussion doesn't
come across as a strong attack against what you're doing!
