Last I checked the A20 only goes up to 960MHz or so:

% cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 
144000 312000 528000 72 864000 912000 96

You can try to overclock it, of course.

Your datasheet is a bit hard to read, but I think it shows size as
100mm x 56.?mm. The FRD39751040V datasheet states 97mm x 57mm. They
both seem quite close in size and I might be able to use the larger. I

Yeah, there it is. I just ran it smoothly on my Beaglebone Black (1 GHz). I've 
yet to try PrBoom on my Raspberry Pi B+ (700 MHz), but I'm guessing it will run 
well on the EOMA68-A20 with it's 1.2 GHz.

Correct. I don't know why I just said "Freedoom". I've tried Freedoom with 
Vavoom and something called "Chocolate Doom" and was rather disappointed...

AFAIK, Freedoom is just a BSD-licensed IWAD (i.e. game content) that can be
used instead of the proprietary IWAD with any number of source ports of the
Doom engine. And since these source ports vary widely in the number of
additional features and capabilities bolted on, it may be a question of
which source port you're using.

I haven't messed with Doom on anything below 1GHz for some years, so I
don't have any specific recommendations for lightweight/efficient source
ports, but you might try several and see if it makes a difference.

I almost find this incredible! Considering games like Doom ran on a few Mhz and 
NO 3D acceleration, I expect them to run comfortably on modern 1 Ghz computers, 
but in my experience Freedoom runs slow as a snail on an ARM board. Is there 
some factor I'm missing? Perhaps the SDL abstraction layer gets in the way of 
fast direct-architecture code?

I'm tempted to see about compiling that free Descent source and see what you 
mean. I have the data files in my possession somewhere.

Maybe you can also use the 4.5” 480x854 IPS LCD that we want to use.

I sent it to Luke, but I don’t know if he can use it.

The price is very similar to FRD39751040V. $8 without touch panel, and
$9.5 with RTP. The problem is that this LCD hasn't entered into mass
production now (now Frida only send samples), and we need to buy
5000 units to enter into mass production.

Here you can see the drawing that Frida sent me:

 yes, but they have to make them by hand (if they're not part of an
existing production run right at the time you ask) so give them a
couple of weeks.

2016-10-18 Thread Hrvoje Lasic
Hello,

Just one piece of advise.

Look on TAOBAO as well. Site is completely in Chinese but it is much more
relevant for sourcing electronic parts in China if you know little bit
around. For example you can register on some of Taobao agents (like
www.bhiner.com), you can copy/paste link from Taobao (and Aliexpress) and
you will be able to see complete translation (fair one at least) as well
they will be able to send goods to you for a small fee. Of course, long
term it is the best to have direct access to factory or some help in China,
however being able to buy on Taobao can be helpful.

I've been looking on aliexpress and found some 3.97" LCD's based on
the nt35510/nt35512. They are similar to the FRD39751040V but have
different pinouts. Does Frida sell sample/single LCD's anywhere online?

The linux driver you posted appears to be for MIPI/DSI mode so
probably not useful for us. I found this RGB24 initialization driver
for u-boot/nt35510. It could be modified for RGB18, then I assume we
could just use the sunxi-fb lcd linux driver?

this happened with descent and descent 2.  the first 3d game ever to
have 6 degrees of freedom. you can look it up (on sourceforge i
believe) and compile it up for DOS as well as linux.  the data files
are non-free (but still accessible) and there is a community around
the engine creating their own maps.

the really *really* nice thing about descent is that it actually works
well on 320x240 on 16mhz 386s all the way up to modern systems.

I had a similar idea, where written into the liscense for the game is a 
"self-destruct" feature. Basically X number of years after initial 
release the game code goes GPL and the assets CC (possibily GPL 
depending on how the copyright law works with re-using the assets in 
later games, especially where voice actors and celebrety cameos are 
concerned)


I can't help but think of Microsoft Train Simulator as a great example 
of why this should exist. It's a codebase old enough that it doesn't 
work well on modern systems, there's still a community interested in 
playing it, and Microsoft isn't doing anything with it. It's not 
available anywhere except for original retail copies getting resold and 
passed around amongst those who are actually interested in some old 
railroad simulator. If that game got GPL'ed Microsoft wouldn't miss out 
on a dime, but they won't bother doing so because "nobody's interested 
in that old thing," and they're Microsoft.

If the ZEOMA will "just plug it in" and work with an EOMA68-A20 cards on offer, 
meaning the drivers provided by the OS can run the screen, wi-fi, etc., then I 
think it is already over half-way done! For instance, I'd just need to install 
the Xorg Joystick driver or make it automatically launch EmulationStation. 
EmulationStation can be configured to launch any libre games practicable. I've 
been experimenting with Zeroinstall for fetching games or versions that are not 
in repos.

Solarwolf runs well on as low as 1 Ghz processors without any 3D acceleration. 
Freedink is probably a good candidate, too. I haven't tried many libre games on 
low-powered hardware so this list needs expansion. Also, games with no built-in 
joystick support will require extra accommodations.

Of course, someone would need to put in the work to derive a pre-configured 
gaming ISO from a Debian or Parabola base. This could be sold on eoma68 cards 
or put on a "specially prepared" SD card to flash eoma cards. If anyone can 
offer some expertise in this area, please chime in.

P.S. I'd like to thank and welcome GaCuest to this mailing list. I had heard 
the ubrewit-zeoma project was a little hard to reach. Collaboration between 
these two communities should be beneficial.

This is true, although programs delivered via non-free Javascript are so 
ubiquitous on the web and the demand for them so high the general practice 
seems to be just letting the user have this Javascript as it is expected 
behavior.

I don't think much can be done except trying to push a user toward a js-off 
experience, but letting them turn it on easily when their website doesn't work. 
This is far from a comprehensive solution though.

Is this the thread about the handheld device? Talk about getting off-topic! :-P

I think that most components are in large quantities in China:

- Linear potentiometer (trigger) and joystick -- Favor Union/Polyshine
(a Hong Kong company). MOQ is higher, but price is very good.
- TFT + RTP -- Frida.
- Battery -- Kamcy (a Chinese company). A lot of chinese companies
sells this battery.
- EEPROM -- The same that you use on laptop/tablet.
- STM32F072 -- The same that you use on laptop.
- Audio IC -- The same that you use on laptop.
- TS4408A button -- a lot of stores sell its in Aliexpress/Alibaba with
good prices: https://aliexpress.com/af/4mmx4mmx0.8mm.html
- SKRTLAE010 button -- you use it on laptop. Have you found a
chinese replacement?
- USB 2.0 -- you use it on laptop. Have you found a chinese
replacement?
- PMIC -- you use it on tablet.
- MicroUSB, microSD and Audio Jack -- you use it on laptop (Runde).
- XPT2046 -- a clone of ADS7843. A lot of chinese stores sell it on
Aliexpress/Alibaba.

What do you change?

I have little idea about electronics, so I try to use the schematic of the
tablet that Luke was doing.

I have seen this:
http://hands.com/~lkcl/eoma/kde_tablet/tablet5.pdf

So it seems, he uses SY7208 to provide 5V to EOMA68.

Yes, my choice of AXP209 is cost-effective and the possibility to reuse
the work of Luke.

As I mentioned earlier, I have little idea about electronics. If I use
SSD2828, possibly I could never do it.

In addition, FRIDA has given me a good screen (IPS, 4.5inch,
480x854, and RGB 18-bit) with resistive touch panel for a good price
($9.5). Perhaps the problem is that the MOQ is 5000 units, but if I
want to do ZEOMA, that should be the minimum selling amount, as
the costs of injection molds for plastic are also high. Produce ZEOMA
in lower amounts would do that the price was very high (as with Pyra).

Do you have a chip picked out to provide 5V boost to the EOMA card
yet? The AXP209 does not appear to provide it.

My plan for handheld computer was to use a TI brand LiPo charging IC
and 5V boost. The AXP209 seems like a better idea than the TI charging
solution since it has configurable regulator outputs and lower cost.

Also, I see you are not using SSD2828 for RGB to MIPI conversion

Yes, our idea is to support all that. I still keep my GP32 and GP2X,
I'm a fan of retro games and emulators.

As I said above, it may be interesting to launch a EOMA68-A20
completely libre with this type of software. Without proprietary
drivers for the GPU to be completely free.

A game console based on emulators and ports can be really interesting even 
before adding non-free software.

For starters, you may be able to find public domain or even free software ROM 
for most of the emulators, and they could even be shipped with the device 
operating system as part of the free software included! Users looking for a 
device to play classic games will of course download what they want, but that 
base set of games will be there, pre-installed, free, and legal. It would take 
some searching and verification, but even a handful of free ROM would be good. 
[PD Roms](http://pdroms.de/) [Community Software](

RetroPie has an interesting project they call 
[Ports](https://github.com/retropie/RetroPie-Setup/wiki/Ports). Some of the 
engines and games they are porting are free software.

Lastly, it could be really helpful to provide a platform target for free 
software games developers. I'd guess that a device that can run/test games

I understand you say.

I also prefer libre games, but the quality of these games are usually
low (projects are very small and without money, I understand it and
I'm not criticizing that games).

My idea is similar to the idea of Luke, when you go to download a
proprietary game, you will be warned that it is a proprietary game
and its consequences.

In my opinion, the problem of libre software is not the existence of
proprietary software. The problem is that developers barely get
economic benefits doing libre software. Maybe we should think
about how developers can make profits doing libre software.

Debian and the FSF have agreed to differ on this: Debian folk have problems
with GFDL with invariant sections, for example. Ask John Sullivan what 
the FSF posiiton is.

Non-free is NOT a part of Debian, nor is contrib - but they are provided
as a covenience for users. It's also worth knowing that security updates
for non-free are almost impossible.
 
BUT ... If you've got a Broadcom chipset, for example, you may have no option 
but to use
proprietary software. Most Intel wifi chips also require firmware - what are 
you going
to do when that's emebedded in a new laptop / nettop ? 

They repostiories do have to be explicitly enabled: the question of whether you 
want
to install non-free software is asked explicitly in the installer - so the 
notifications
are there.

Ironically, if wifi adapters / Ethernet cards still came with burnt-in firmware,
Debian would be a fully free distribution (and it's worth remembering that 
Debian
was endorsed and funded by the FSF for a while).

If you want any architecture other than Intel / AMD as a primary supported 
architecture
then your choice is prety much Debian from the mainstream distributions and 
Trisquel / GNewsense
are forks which don't yet support all other architectures. So, if you want to 
do work to
enable your project on a Cubietruck - you use Debian, probably.

Not a all, but that was a rhetoric question.
I am looking forward to make pedagogic help for basic users, I was one
myself and I know that even a bit of more help (more that just a popup)
isn’t that hard to help, it's just very time consuming.

Debian's approach of this isn't really ethical.
Anyone has the freedom of install installing propitiatory software even
non tech users.

Including non-free software in the repository is insisting/proposing
users, especially non tech ones, to give up their freedom for simplicity
without understanding the importance of them and the technical problems
that non free/libre software brings (a good example of that is the game
modding community).

Mainstreams users like you seem to refer to them are what makes software
and hardware go in decadence.
I don't say that they are directly concerned, but it is how their were
treated like, that made them what they are now and ask the same bad
products.

If you continue to give them what they are made of the project will
slowly become like them and only enforce the already bad circle.

Their are already lots of free software games, seek the libre game wiki
encyclopedia.
https://libregamewiki.org/Main_Page

Note: emulators can be free software but the roms/blobs shouldn’t be
included, f-droid already does that.

My idea is to offer a completely libre console that anyone can improve
it and anyone can do whatever he wants with it.

My idea is that this freedom allows you to install what you want. For
example, if you want, you can install a completely libre OS (like Parabola
OS) or you can install a proprietary OS (like Windows, if there is a
EOMA68 compatible in the future).

On the other hand, my idea is to focus on a EOMA68-A20 with
GNU/Linux OS (Debian perhaps?). Would be sent without any proprietary
software. When you turn on it (first time), the OS will ask if you want to
download the proprietary drivers for the GPU and if you want to activate
the repository with proprietary software (such as proprietary games or
emulators).

I would also like to offer a EOMA68-A20 card with Parabola OS and other
with Android OS. While we may not provide support for these cards
(for lack of money and time).

 it's an *ethically* focussed project of which it so happens, by way
of the four freedoms being designed around the extremely rare and
hard-to-understand *joint* combination of software development *and*
ethical considerations, that libre software is a huge part *of* the
project but it is not *the* focus of the project.

 now, if people want to *ignore* those ethical considerations they are
entirely free to do so and to experience the consequences of doing so
(which, if they piss on anything that is part of this project,
interfering with it or bringing it into disrepute in any way, then to
say that those consequences would be bad for them would be a massive
understatement).

 they're not [out of the question].  they will not be able to receive
an RYF Certificate, that's for sure, but that's nothing to do with
EOMA68.

 if you recall a couple weeks ago i began writing up the specification
to incorporate the circumstances under which proprietary software is
acceptable, as well as outlining the [rather large] burden of
responsibility that proprietary software vendors will be taking on as
a result.

 if that proprietary software is installable by the end-user (over the
internet) *after* the product ships, that burden is greatly reduced.
if there isn't *any* choice *other* than proprietary software however,
such that that proprietary software might as well already be on the
device, i might however get a bit unhappy about that.

 it's still all forming, basically, but the fundamental underlying
rule is: ethical considerations FIRST.  stop causing people pain and
distress just because they're buying technology devices.

Actually, I personally take a hybdrid approach to my libre software. I 
focus on the important components being libre, but if some high-level 
software isn't, I can live with that as long as I'm not dependent on it.



So with that in mind, I know I would play some emulators on there. Also, 
if we just focus the EOMA68 projects on fully-libre usecases, we will 
miss out on many mainstream users who are necessary if we want the 
standard (or whatever revision its reached by then) to be at all

libre software stack, but with easy options for the user to choose to 
add non-free components if they wish (like the Debian non-free 
repository being only a couple of clicks away)

Hello everyone.

I suppose many of you know the handheld games console project
based on EOMA68 (the provisional name is ZEOMA).

The website (it is outdated (the images are also outdated), when the
project is more advanced I'll update) (thanks to Peter Bouda) is:
http://www.ubrew.it/

The features of the console are:
- 4.5 inch 480x854 IPS screen.
- Resistive touch panel.
- DPad + A B X Y buttons + R button + L button + 2 Analog triggers
+ 2 Analog Joystick (with push button) + Start + Select + Home
+ Vol +/- + 2 extra buttons.
- 4000 mAh battery.
- Stereo.
- MicroSD slot.
- USB 2.0 Host.
- MicroUSB (for charging).
- STM32F072 for controls.
- AR9271 WIFI.

I have done a small block diagram you can see here:
http://george.the-petries.co.uk/shared-write-access/eoma/Block%20Diagram%20ZEOMA/Block%20Diagram%20Console%202.0.jpg

I have placed the datasheets of the components here:
http://george.the-petries.co.uk/shared-write-access/eoma/Datasheets%20ZEOMA/

I have no prior experience designing schematics and PCB, but I will
try to do my best. If I have any questions, I will ask you.

I will publish all the schematics and PCB under GPLv3+.

If anyone have any suggestions or improvement, I appreciate it.

Thanks to Luke for all his help. Also thanks to Alexander for allowing
us to store the files of the project in his server.
