Hi,
Just trying to expand the EOMA ecosystem.
I've got Realtek RTD2660 dithered LCD driver I bought
with 800x480 7" display. It converts a 1024p HDMI signal
to 800x480 and dithers the pixels to give impression
of very high definition. (The illusion is a challenge
for small characters that need to be displayed.)
It works well for graphical OS like Ubuntu running on the EOMA.
Just wondering if anyone know of SDKs and all the
developer bits needed to get RTD2660 board built
for EOMA.
(I …
[View More]believe Raspi developers are thinking of making such
a device already and have a kickstarter like campaign
going.)
So effectively the project is to build a miniature open source
HDMI monitor for EOMA all done up in glorious KiCAD.
When I get access to a 3D printer, a 100% open sourced case design
is likely a done deal.
The chip cost <$2, and LCD about $14.
Add in all the components, and you could make
decent micro HDMI monitors with BOM of about $20.
Anyone out there wanting to cooperate on this one?
I can do all the layout and LCDs to get the thing going
from a hardware point of view.
I can buy a programmer to program the RTD2660 chip.
What I don't have is the SDK to customize the chip.
But obviously need some kind of SDK to make the firmware files.
I don't particularly know what to get it, or if there
are are open source projects out there that can generate the
firmware and/or program the RTD2660 chip
Any pointers greatly appreciated.

OK, so I got an MEBv2 eventually a week or so ago, and with some help
from phil hands at the mini-debconf last week proved my card would boot,
then we built suitable uboot, and tools and have just faffed about
soldering serial header, serial cable, power cable up and sorting out
level shifters, but now I can boot and get serial. Woo!
Now I just need to sort out rootfs and kernel, solder on IO header,
suitable sata connector and I can work on something useful like debian
installer support.
So, …
[View More]I have to fit htis in round way too many other things, but hope to at least contribute a bit now.
Wookey

Hi,
Luke/Aaron, you need to get some shoes on
and go make a mini HDMI connector that is a little bit smaller (so as to
prevent it being used as a video connector) and use it as ethernet
connector.
Notice all the tablets out there don't have physical ethernet?
For lack of a decent substitute ethernet connector that is thin enough
to go on a tablet.
It could be designed so that future EOMAs could have it and so too
should the Plasma Active tablets. And thin stacks of future server
boards.
…
[View More]You guys need to use your industrial contacts and muscle and go pull
some strings to make it happen. The alternative is I go make it in
mini-HDMI size and just make cable adapter (which will lead to
confusion). I'm sure my adventure will end in tears and a sorry mess but
it be better than nothing.
HDMI has at least 4 tx/rx pairs and a lot more - just use the tx/rx
pairs only and its good enough to get gigabit ethernet.
The ethernet magnetics chip is very small these days costing under $1,
so the overall solution could fit inside an EOMA.
There is some standard out there milling around
to support ethernet through HDMI, but I don't fancy that as a better
solution than a low profile dedicated ethernet connector long overdue
for the tablet market to replace the bulky RJ connector.

quick update. a few more tasks and this PCB will be pretty much ready
to go. it's far less complex and much less space-intense than the
tablet PCB (which could only be single-sided). a few scary areas like
the GbE routing. there will be plenty of stitching vias to earth that
lot...

uh... am i reading this right - that this router design could be up to
20 watts?? 4x USB2 @ 500mA (10W), 1x RTL8366 (3W) and an EOMA68 CPU
Card (4W). That's.... a hell of a lot.
anyone any experience at dealing with that much power on small boards
(4 amp @ 5V) ?

Dear OEMA68 developer community .
We are a team of Spanish engineers who are developing a Home Cinema
-Media Center to integrate XBMC on Linux on a modular concept .
We thought we had EOMA68 use platform for our project.
But note that not included SPDIF output included in the CPU to one of
the GPIO outputs as expecificacion see that the original is not
contemplated.
We think that in a Media Center is mandatory to have a SPDIF
connection because sometimes only play music and it is …
[View More]interesting to
connect the audio DAC you have, no need to convert from HDMI .
My question is ..
The EOMA68 espeficicaciones the A- 20 are closed or else you could ask
implement this output to a GPIO ??
- In event of failure to implement GPIO , I noticed that the photos of
the first prototype boards last is eliminated auxiliary bus had on top
.
It would be possible to go back on the design some kind of signal
SPDIF auxiliary bus and maybe some other CPU signal discarded but
interesting in specific applications .???
