lkcl: Rockchip ask $5000 to give you SDK with binary blobs and proper documentation
<Tsvetan>
also they do not have any distributor which have experience to sell chips outside china
<Tsvetan>
for the moment I try to buy 72 pcs via friend in China
<Tsvetan>
and after signing NDA they gave me schematic and BGA ball assignments
<Tsvetan>
free of charge ;)

Hi FergusL
<AutoStatic>
I've updated the Wiki
<FergusL>
*looks for the link or a tab of the wiki*
<FergusL>
ha, I see the modifications, nice
<FergusL>
if you read the backlog you'll see there was some more conversation about "who's this wiki and channel for"
<AutoStatic>
Yeah I've read it
<AutoStatic>
I'm all ok with that
<FergusL>
cool

<FergusL>
well actualy he is sure about it
<FergusL>
there's even a chance the chip itself is too

FergusL, this is rockchips channel :)

sorry

you're right

<hramrach__>
FergusL: still cubiboard.org has link to shop and miniand sells them too
<hramrach__>
well, link to miniand is there too iirc
<FergusL>
well, yes, it's marked as out of stock, I don't know about Europe stores
<FergusL>
not even sure there was stores selling it
<hipboi>
FergusL, if you want to buy, i can open the r0ckstore
<hipboi>
FergusL, about 15 pcs left
<FergusL>
hipboi: oh, it's very nice from new, but I don't need one so badly, I can wait
<hipboi>
FergusL, ok
<hipboi>
FergusL, then i will send mail to those who asked for notification when back in stock
<FergusL>
ok

eebrah|away is now known as eebrah
<FergusL>
is there CVBS aka composite video in Rk chips ?
<FergusL>
I just realised A10 (and maybe A20) has it
eebrah is now known as eebrah|away
<Astralix1>
nope. not known to me
<Astralix1>
the RK support some standarized digital video formats on their LCDC interfaces, so probably there are interface chips available.
<FergusL>
some Rk3x based devices are sold with thos RCA cables that do have video
<FergusL>
what they often cal "AV out"
<FergusL>
but that could just be very wrong
<Astralix1>
lcdc interface is part of separate document besides TRM what we dont have
<FergusL>
ok
<Astralix1>
TV Interface: ITU-R BT.656(8-bit, 480i/576i/1080i)
<Astralix1>
So with some simple interface chip CVBS should be possibel
<FergusL>
just looked at the RK3066 full doc and haven't found anything so probably yes, nothing there
<Astralix1>
the above is 3188
<FergusL>
where have you seen this ? confidential doc ? :)
<Astralix1>
as you said, confidential doc
<Astralix1>
TV Interface: ITU-R BT.656(8-bit, 480i/576i/1080i)
<Astralix1>
3066 has same option
<Astralix1>
chapter 22.1 of 3066
<FergusL>
idea : add a row to the CPUs table with "Available doc"
<FergusL>
ultimately maybe each processor could have its own page
<Astralix1>
we are thinking of how to supply the docs.
<FergusL>
what is "we" ? are you working with Rockchip ?
<Astralix1>
the 3066 are out in the wild but not anyone is willing to add an account o a hoster that has only characters that you cant even try to read
<Astralix1>
no
<Astralix1>
i am not related to rk in any way
<FergusL>
okay
<FergusL>
hm, maybe by tv interface it means the corresponding tv standard
<FergusL>
bt.656 is one
<FergusL>
color primaries, curve etc...
<FergusL>
because I can't find any other mention
<Astralix1>
Hmm... BT.656 is same as ITU656 and that is a simple digital video interface.
<Astralix1>
I think there are a lot of cheap and simple converters from CVBS to ITU656 but the other way round could be tricky
<Astralix1>
nobody wants to have such old analog signal anymore
<FergusL>
yes, true
<FergusL>
but the cheapest available small screens are analog video
<FergusL>
the rPi has is, the Cubie has it too
<Astralix1>
nope
<Astralix1>
RPI has TV out in SOC
<Astralix1>
and in the case you need small LCD, use one with compatible digital interface that works with LCDC inside RK directly
<Astralix1>
it is highly configurable
<Astralix1>
it tells to even support SPI LCDs
<FergusL>
yes rpi has tv out in soc, why "nope" ? is TV out not the same as cvbs ?
<Astralix1>
yes it is
<Astralix1>
nope for thinking the wrong way
<Astralix1>
If you want to connect an LCD you should use the LCD interface and not convert a singal as often as it neeeds to be a bad signal
<FergusL>
Astralix1: can you give reference or link for the lcd screens you're thinking about ?
<Astralix1>
uff...
<Astralix1>
There are a million different glasses outside
<Astralix1>
and most of them are available for some month and then the on glass controller is exchanged...
<Astralix1>
So some more details needed :)
<Astralix1>
what would you like to have in size and specs
<FergusL>
between 3.5" and 7"
<FergusL>
I've found small analog screens between 20$ and 50$, they are sold as screens for cameras in cars
<Astralix1>
ok
<Astralix1>
so you need the spec of the glass and compare it with the options of the RK3xxx
<Astralix1>
unfortunately the lcdc doc is not included so you need to contact RK
<FergusL>
I thought about going the other way roudn : what inputs are easily available or hackable, so that I could find a matching screen in the same price range
<Astralix1>
but datasheets are sold together with sdk, so you have to sign NDA and pay 5k$ for the data you need
<Astralix1>
you coud try a different approach
<FergusL>
we should pay it all together and leak everything
<Astralix1>
you buy an SPI compatible LCD and use one of the spi ports to run it
<FergusL>
true, yes
<FergusL>
also, are these recognized as true screens ? I guess the Video Out on RaspPi is
<Astralix1>
uh!
<Astralix1>
there was someone really busy writing wiki...
<FergusL>
I shouldn't say "true screen", rather, a screen that is detected by X
<FergusL>
ha ?
<Astralix1>
someone filled the complete procedure how to compile rockchip kernel...

Astralix1: "just make kernel.img works fine" because there is mkkrnlimg binary in kernel source tree?
<naobsd>
it will not work if someone try to make kernel.img on Linux/arm ;)
<naobsd>
boot.img(kernel+ramdisk) and kernel.img+boot.img(ramdisk) can be chosen, so there might be one another page between 'building kernel' and 'flashing images'
