<Tsvetan> 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 ;)

<FergusL> hi AutoStatic
cnxsoft has joined #linux-rockchip
<AutoStatic> 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

<hipboi> FergusL, this is rockchips channel :)
<FergusL> sorry
<FergusL> 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

<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> yes jochen is trying to rescue something
<Astralix1> as what was written there is completely wrong
<Astralix1> what a mess
<FergusL> you could have changed you too
<Astralix1> what?
<FergusL> what was wrong ! you could have modified it too !
<FergusL> it's open
<Astralix1> Yes
<Astralix1> Toolchains are wrong
<Astralix1> and reversed
<Astralix1> you can compile 2918 with 4.6.3 hf but you can do 30xx and 3188 only with 4.5.3 maximum
<Astralix1> the wressling with initramfs is part of separate manual of how to create your own linux booting up, not Android
<Astralix1> You cannot mix the several listed github sources as most of them are incompatible
<Astralix1> so picking out your matching board file doesn't work
<Astralix1> description of making the kernel image is simply wrong
<Astralix1> just make kernel.img works fine

<naobsd> 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'
<naobsd> 'preparing images'
<naobsd> http://linux-rockchip.info/mw/index.php?title=Installing_new_kernel_image kernel can be read from kernel partition if recovery partition doesn't have kernel
<naobsd> I'm not sure it's good thing to split kernel from recovery.img (if kernel is dead, recovery is also dead)
<naobsd> I'm not sure non-GPL host tool such as mkbootimg/rkcrc can be added into kernel source tree
<naobsd> ah, source code of host tool, of course
<naobsd> but if it needs to be GPL, I can change rkcrc license to dual BSDL/GPL license
<naobsd> cya
