[Arm-netbook] IC3128 1280x800 60fps confirmed

[Luke Kenneth Casson Leighton]

http://rhombus-tech.net/icubecorp/IC1T/news/

ok, it's kinda cheating, as it's only 8 bits per pixel, but i managed
to get a stable image at 1280x800 resolution, 60fps, on the
micro-desktop base. yet to be determined is what's actually the
limiting factor - i'm working with ICubeCorp to find out - it's either
that the DDR3x16 RAM IC (which is actually a 1600mhz samsung x16 DDR3
chip) is being clocked at only 266mhz or that there is an internal bus
which can't get memory fast enough when reading the current scan
line/pixel at the framebuffer's memory.location..

all kinda fascinating. what i am speculating is that this 55nm chip
could actually be run much faster than the reported 400mhz speed. a
processor in 55nm theoretically should be able to achieve 600mhz
comfortably, possibly even 800 and maybe 900 with a bit of luck.
however that's a huge jump in power requirements and i don't think the
power in (pins) have been designed to cope with that.

so... we shall see :)

ICubeCorp have asked to keep a little bit below the publicity radar for
now as they are busy dealing with clients on whom they are dependent to
prove that their *entirely new* instruction set is viable commercially.

the only reason that they are talking to me is because i am one of the
few people who willl a) not be a drain on their available resources b)
knows the software libre ropes c) can work things out and bugfix and help
them out occasionally.

to make it clear: the last thing they want is for lots of inexperienced
people to be contactting them at this very moment so a tweet would really
not be a good idea.

anyway: i have one final thing to sort out, it's the LAN9512 which i
slightly messed up, if i can show that there is a chance it can be
corrected then i can add ithe EOMA68-IC3128 cpu card to the crowdfunding
campaign. however i may just have to simply redo that circuit and find
another $1600 from somewhere to get another run of samples done. i am
reviewing beagleboard-xm and other circuits which use the LAN9512 to see
what i can do.

If that cpu card would imply endorsement by the FSF I would assume it
would be of value to the product and the campaign. Having suggested the
current proposal to some friends the response was that for them to buy a
board of relatively low performance, it would at least have to be
supporting free software. The argument of buying into freedom with
EOMA68 doesn't seem to cut it. Maybe others have got similar responses?

Is there any idea when the campaign will launch? I was considering
contacting all website where the Improve, Spark Tablet or Vivaldi tablet
were featured (Liliputing, Phoronix, Slashdot, Jupiter Broadcasting)
since it would be a great follow-up on this previous story. Also for the
updated story on e-waste tying into Phoneblocks or Fairphone and for
similarly It could be positioned as the low-cost alternative to the
Novena laptop, as I heard some complaints about the price during a
conference.

Maybe putting up a community-marketing page for coordination would be a
great way to make sure all mayor news outlets are target for the
campaign.

Can't wait.

noow you're getting it.

supporting free software.

well, a) the IC3128 has a compiler (i have the source now), android
ported (i have the source now) and a qemu emulator (still waiting for
the source on that) and *that's it*. so if you want anything else you
are *literally* going to have to compile it from scratch. but b) the
other one that's FSF-Endorseable is the ingenic JZ4775 card, and that
_does_ have full GNU/Linux OSes including of course debian
pre-compiled.

unfortunately however the current contract is finished so unless
someone comes forward with the money to pay to have a prototype made
up of the JZ4775 CPU Card it will remain unavailable.

when the things on the TODO list are completed. these include:

* completing the video (going to have another attempt today)
* completing the initial list of rewards
* waiting for the prototypers to complete the first wooden case

yeah the novena has a lot of features including extremely high-end
screen and an industrial-grade processor, and it's being made in small
quantities. although people may believe the price is high it actually
really isn't.

i want to wait until the pi-top is available and its CAD/CAM files
released, then we make a modified version that takes an EOMA68 CPU
Card.

good idea! do you want to start that? i created a blank page

hang on have to talk to phil as it's saying "do not have permission
to access....

I'd love that. Personally I'd be able to create a case myself, but I'm
afraid of buying incompatible peripherals (screen, battery). Buying a
kit would therefore be great option.

http://rhombus-tech.net/community_ideas/micro_desktop/marketing/

I've put up some initial content on the page. Seeing the list of
websites having covered related products, there is a need to get some
buzz going around the campaign in order to create similar or even
greater reach. When some marketing-material is available (like a more
elaborate landing page on crowdsupply) notifying the world about the
news would be great.

I was thinking about creating some templates (or even just sentences)
for contacting people about the project. In that regard I'd like to get
information and feedback on the marketing message.

I've set apart the category of podcasts because it offers the
opportunity of having interviews around the campaign (audio or video)
which creates a lengthier time-frame for getting the message across.

More importantly it would be great if everyone could spare a minute to
check the page for their known marketing channels and suggest the ones
that are missing. Thanks in advance!

i'll take a look.
