Someone brought up the EOMA68 at the Olimex forums and it is clear from that
discussion alone that there is a lot of bad blood between you two:
Frankly, I'm not interested in those kinds of ego clashes and speculated bad
intentions. I know you both have made contributions to freedom in digital
technology, that I appreciate. This is what I find to matter the most.
I am not sure Olimex's boards have shipped with Allwinner's GPL-violating
software preinstalled (some of them do not come with NAND). It is regrettable if
they did and it would have been much better to avoid that.
I think that offering the GPL-violating software for download separately would
have been a lesser evil (even though not quite acceptable). Perhaps this is what
they did, perhaps not.
Either way, I do not need to have an umbrella statement about Olimex as a
company. Their products helped the freedom in digital technology front and I'm
grateful for that. Perhaps they also did bad things, such as promoting and
distributing GPL-violating binaries. But so do a great number of other companies
that are also doing good on some aspects and much less on others. This is the
case of Google, IBM and many other.
I think such general considerations are only relevants to evaluate whether an
individual or a company is dedicated to helping us solve digital technology
freedom issues, or is only doing it sporadically. In that case, you may conclude
that Olimex falls in the latter position. I'm personally not quite sure about
it, but I do agree that shipping Allwinner's GPL-violating software is a
drawback in that regard. However, as I've mentioned before, I know first hand
that Olimex has been supportive of the linux-sunxi community (when many, many
other Allwinner board vendors barely acknowledges it).

I have to admit that had skipped my mind when writing those previous emails. I
do recall that linux-sunxi was initially started on the arm-netbook mailing
list. And indeed, I also recall seeing your name around for a long time.

That's making an umbrella statement about Olimex, which I don't think is very
relevant. There's good and there's bad there.

I have to say, this sounds over-exaggerated to me. In French, the word "crime"
only refers to the most serious offenses. But Wikipedia apparently states that
crime is not so precisely defined in English. Oh well.
Still, I don't really see a need for pointing fingers this way. Stating that the
distribute GPL-violating software is the informative thing to do. I don't see
the point of getting personal about the company with harsh considerations
(however technically correct these considerations may be). It also feels like an
attempt to discredit Olimex, to be honest. I believe all parties would be better
of without that kind of heat, by staying factual and informative.
Also, let's not forget that Allwinner's the culprit for all this mess in the
first place. Olimex may has been a distributor of it, which may be the same from
the copyright law's standpoint, but I think it makes a big difference. You may,
of course, disagree with these personal views.

Then you were, in fact, in the same position of distributing GPL-violating
binaries. Unless you stripped them off off that release?
I think this makes you understand the kind of tricky position this leads to.
People need those GPL-violating binaries (for some of them, for direct use, for
others, to do reverse engineering), so I wouldn't send the first stone to the
distributor, but to the company that caused the problem in the first place.
So nobody wants to distribute them, but people need them. I'm really not sure
what the right thing to do here. And frankly, if everyone had stayed away from
it with a ten-feet-pole, we wouldn't be here today.

You don't need to. Those are past stories, I'm rather interested in the state of

Of course, I'm not surprised. And I know that Olimex was only able to use KiCad
for such a complex project at the cost of lots of efforts, bugreports, etc. But
I'm really glad that they did and this is the kind of extra step that makes me
believe Olimex and Tsvetan are not only there to collect money but actually want
to push things forward on the freedom-in-technology front.

This is interesting background (I'm quite familiar with it, but others may not
be, so it'll probably help them realize what a task designing that kind of
circuit board can be). Thanks for sharing it.

I'm not sure this would solve the multi-layer requirement. Also, a standard
interface does have drawback, as it limits the possible number of interfaces
exported by the SoC board.

Yeah, definitely. We're still a long way from that being a reality comparable to

I wouldn't expect those kinds of automatic imports to be 100% reliable,
especially for complex designs though. But it's great that it's there.

Whatever suits you best! But why stick to Allwinner platforms? Rockchip
platforms such as RK3288 (and possibly the upcoming RK3399) do just as well in
terms of software freedom. I guess you've also considered the i.MX6. GPU support
is being reviewed upstream as we speak. Tegra K1 is also really nice, but
perhaps more power-hungry. Is this really an issue for a non-mobile device

Well, I guess it depends on your timeline. Perhaps free software support won't
be ready in time for the next generation of your products. Or maybe it's not
that interesting on the technical side either.

I would tend to agree with you on this one. Hardware manufacturers have leverage
in those situations, so it's sad that they don't use it.

There's probably a wide range of possible explanations for this. It's not
certain that these companies' volumes matter. But either way, I'd be interested
in starting that discussion to see where each actor stands on this.

Same here, sorry for not connecting the dots earlier. I'm now under no

It may not be the most efficient strategy, but I'm saying that it's something.
The situation is much worse on a number of other platforms, where we have no

Again, I'm not saying it's optimal and good as it is. But it's something and has
lead to results (that were, indeed delayed by years due to the technical burden
that Allwinner induced by requiring the community to do reverse engineering).

Again, I'm not sure I fully share your stand on Olimex, but I sure am glad to

That's probably a fascinating read, but you're again talking about an approach
here, not technical differences that matter from the perspective of freedom in
technology, about the product you're releasing now. This is the specific aspect
I wanted to highlight and get feedback on, not your general attitude.

I believe the PCB design is the source form of the technology. Printed circuit
boards are the product form and the technology itself can be referred to as
"circuit boards". Just like software (form of technology) has source code
(source form) and binaries (product form). We can distinguish that from
Integrated chips, another aspects of digital technology.
I will be (and have been) using this specific terminology. I rarely talk about
"free hardware" in general (and even less so about "open hardware'. However,
this confusion is very common, so it's good to bring it up.

Digital technology refers to digital electronic technology, which includes
software, hardware configuration, circuit boards and integrated circuits.

Well, what I asked was what I was missing about digital technology freedom
aspects, not what other aspects I was missing. I'm well aware that your project
comes with a much broader approach, that you have described a bit already
throughout this conversation.

Again, I think you're misunderstand what I'm asking here. I'm not asking about
the approach (but feel free to provide a comprehensive introduction to it, I
feel it is quite interesting). I'm talking about the specific level of support
of the products you're releasing now in regard to freedom in digital technology.
Also, I can guess how vast your effort is and how much work it represents. This
most certainly naturally explains why it took such a long time to actually get
something concrete produced from all these ideas.
And frankly, I'm not one to make personal attacks, so I don't think you have to
fear that sort of reaction from me :)

Yes, I am well aware! Such a great thing to have. It has severely alleviated the
pain associated with Wi-Fi.

True, they just got it shipping faster (Bunnie is quite used to EE and the
Chinese circuit-board-making ecosystem, so that must have been a great help).

Really? I haven't seen any such example, and I'm not sure that Google will allow
any company to do this under the ChromeOS brand name. But I'm all ears for

Well, they have been using eMMC modules on ARM devices because most of them
don't have SATA or PCI-e interfaces. But I seem to recall that earlier x86
Chromebooks did use SATA disks. This is anyway a very common practice on those
kinds of devices. And any MMC card (soldered or not), just like any USB storage
key, comes with a proprietary firmware.

From a technical perspective, I don't think this has been a drawback for
ChromeOS devices. And they're continuously updating the system, too.

Again, not sure it's that. SDIO Wi-Fi modules have been really common all along.
And either way, it would be hard to replace them as everything's soldered
together. As long as we can use an external Wi-Fi dongle that runs with a free
firmware, I think we're good. This is why I don't focus on the Wi-Fi part that
much. Other aspects such as GPU support are a clearly much bigger task to

Either way, I agree we can't expect them to always make the choices that will
benefit freedom first.

Glad that we're good on that :) And yeah, I guess having to explain things makes
it a lot easier to present them clearly afterward.
