morning all, does anyone know where i can get an RK3288 Reference Design that has 4 DDR3x16 RAM ICs and eMMC? i need PADS 9.5 for the PCB layout
<lkcl>
i'm finding a few people on taobao who sell them (!) and some also on prog3.com but it's in chinese and i can't work out how to download from there

stdint: ping
<stdint>
lkcl, hello
<stdint>
pong
<lkcl>
stdint: really grateful to paul for introducing us.
<lkcl>
just replied to your message
<stdint>
that is what I have known
<lkcl>
perhaps an immediate thing you may be able to help with: i need an RK3288 reference design (PADS) so i can begin immediate work on prototyping a board. any ideas where to get one?
<stdint>
I am sorry, my supervisor may not understand what I said, but I would try
<stdint>
lkcl, I don't think the rk3288 could support more than two dram chip
<lkcl>
stdint: ah can i suggest waiting until we have established a bit more background for you? this is a *long* project i have been doing
<lkcl>
stdint: i've seen a number of designs out there which allow 4 RAM ICs

* lkcl
goes to look for some...
<stdint>
lkcl, I think the rk3288 only have two cs line for dram
<stdint>
but please give me a introduction a bit more about background
<stdint>
it is a little difficult to collect things together and convince a supervisor
<lkcl>
stdint: sure. i'm a software libre engineer who is also now a hardware engineer, i've created a modular standard called EOMA68 as a way to make it possible for people to upgrade and save money.
<stdint>
you don't need to buy those document I think, but I have let my supervisor whether I could release some documents
<lkcl>
EOMA68 is designed as a long-term mass-volume standard, so although it's just starting out, it's designed to ramp up to millions of units within a few years.
<lkcl>
stdint: base units (called "Housings") are designed around the principle that they never have to be modified ever again.
<lkcl>
there are two housings currently available: a micro-desktop unit and a 15.6in laptop unit.
<lkcl>
stdint: it's quite complex and comprehensive, and can take a *lot* of explaining.
<lkcl>
stdint: it may be best if you view some of the videos, for example this one:
<stdint>
and please tell me where I could find your name like in kernel source or some other place
<lkcl>
stdint: search for "luke kenneth casson leighton" or "lkcl".
<stdint>
I see thank you
<lkcl>
i've been involved in software libre since 1996. i'm one of the original team that worked on samba
<lkcl>
i was directly responsible for bringing NT Domains interoperability to samba
<lkcl>
i've published over 200 articles online
<lkcl>
i stopped adding to my c.v. a few years ago after it got to 15 pages in length
<lkcl>
:)
<stdint>
I am in charge of hardware video encoder/decoder now
<lkcl>
stdint: oo interesting!
<lkcl>
stdint: that's an area which, if it is libre, makes a big *big* difference to the acceptability (and also product reliability) of a processor

phh, hi, the bug of hevc is found
<stdint>
the application and driver would be released in a short time
<stdint>
but please ignore the code quality
<stdint>
paulk-collins, I have bought a wifi dongle and I would try it in the weekend
<phh>
Awesome thanks
<phh>
It will be vaapi?
<stdint>
no, but plugin in gstreamer
<stdint>
vaapi have been proven can't work in parrallel
<stdint>
so it would perform badly at 4K resolution
<stdint>
I am going home now, talk to ayaka
<paulk-collins>
stdint, yay, thanks a lot!

ayaka: erm I've got nothing against gstreamer, but when I wanted to test it, I couldn't find how. only software I could find which uses it is gstreamer, and I've read that's it's incompatible with gstreamer-vaapi because of window initialisation
<ayaka>
phh, do you use the vaapisink?
<ayaka>
I think that plugin would be dropped
<ayaka>
I have talked to the Intel gays, it seems that they have dropped the display system in VA-API
<ayaka>
leaving those job to external application
<phh>
I don't know. I just started totem, i've seen hw accel doesn't work, i got some google result telling me it's expected, and i stopped there
