08:27 <AstralixNB> Does anyone have a Datasheet for companion chip RK618?

12:27 <deviker> Hi, I've been using a mk908 v3 stick for weeks without problems and I bought another one. It looks the same with the same rev number 2013.05.13 but it has DIFFERENT RAM chips. Now I've flickering allways. The only custom kernel I found working well is jjh_V_#135 but the latest jjhmod kernels give the same probem.

12:30 <deviker> The stick that works well has GEIL 1331-1320 chips and the "faulty" one GEIL 1330-1324

12:31 <deviker> both sticks have the same silkscreen (netxeon mk908 v3.0 2013.05.13)

12:35 <deviker> the faulty one only works well with jjmod kernel jjh_v_#135 but it's /proc/config.gz is not different.

13:33 <mosquito520> AstralixNB: what kind information that you need?

15:03 <AstralixNB> mosquito520: best would be a complete datasheet. I bet it is a HDMI interface as it replaces the ITE chip in some newer tablets.

16:03 <mosquito520> AstralixNB: well, first request has been reject...:p

16:04 <mosquito520> AstralixNB: the second, it's not only HDMI transmitter, it combined some block that RK3188 does not include in:)

16:06 <mosquito520> hm... I can't find it on google:~

16:06 <mosquito520> :/

16:08 <AstralixNB> believe me, I already used google before requesting it here

16:09 <mosquito520> Ha, I mean...If I can find the exactly file name on google, maybe i can figure out which link that you need:)

16:13 <AstralixNB> It is more likely to find something on these chinese datasheet search / exchange engines. But I don't write enough chinese...

16:18 <arokux> hi Astralix1

16:18 <arokux> and hi AstralixNB :)

16:18 <arokux> any progress with RK bootloader?

16:18 <AstralixNB> hi

16:18 <mosquito520> Hi arokux :)

16:18 <AstralixNB> Too much work

16:19 <arokux> I see

16:19 <AstralixNB> actually I just did some small progress on the mainlining

16:19 <AstralixNB> But it is progressing slowly cause I am despreately missing PMU and CRU documents

16:21 <AstralixNB> the whole clock setup has to be reproduced by reverse engineering

16:23 <arokux> AstralixNB: what about the released code?

16:24 <AstralixNB> It is open source, just check me and mmind00 at github

16:25 <arokux> AstralixNB: no-no, I mean, is chinese code not enough to understand clocking business?

16:25 <AstralixNB> check the linux-rockchip repo and in that use the topgit/devel branch

16:29 <arokux> AstralixNB: no-no, I mean, is chinese code not enough to understand clocking business?

16:30 <AstralixNB> Sometimes yes, sometimes not.

16:32 <AstralixNB> Problem is, that there are some bugs inside the SOC. Not really bugs, but if you see that some GPIO cofigs are reversed, compared to others...

16:33 <AstralixNB> So if you look at the data sheet you just ignore this by scrolling it. But if you then see the code and see that there is additional logic implemented, you check the datasheet twice. And this combination brings you to the goal.

16:34 <arokux> AstralixNB: same with Allwinner. one can see that the docs are not really full and are written on-demand.

16:34 <arokux> https://grabcad.com/library/radxarock-1

16:34 <AstralixNB> Same with RK

16:35 <AstralixNB> I got the comment from RK that they do not release some of the docs as they are still busy writing them, or they wrote them, but never checked validity

16:35 <arokux> :)

16:35 <arokux> AstralixNB: there have been rumors in this channel RK has added support to U-Boot

16:36 <arokux> mosquito520 hinted at that :p

16:36 <arokux> AstralixNB: do you know something about it?

16:39 <AstralixNB> I heared only rumors

16:40 <arokux> mosquito520 hinted at device which should have it, haven't checked it out yet.

16:42 <arokux> AstralixNB: I've odered pins from Hongkong, but they haven't come yet :(

16:42 <AstralixNB> pins?

16:42 <AstralixNB> bowling pins?

16:43 <arokux> AstralixNB: 2.54" pins

16:43 <arokux> AstralixNB: http://a.pololu-files.com/picture/0J1036.300.jpg?acbb5b9ff41797e00c356bd801e43fa2

16:43 <AstralixNB> Ok, I order them at farnell or digikey

16:43 <AstralixNB> call today, get tomorrow

16:44 <arokux> AstralixNB: Radxa ppl forgot to solder UART pings...

16:44 <arokux> AstralixNB: how do you cope with minimal order at digikey?

16:44 <AstralixNB> You should have asked, I probably would have sent you some for free

16:44 <AstralixNB> I collect orders from mates in the company

16:45 <AstralixNB> So, have to leave now

16:45 <AstralixNB> see you later

16:45 <arokux> have a nice evening AstralixNB

16:46 <AstralixNB> thx

16:51 <mosquito520> hm:/ AstralixNB is offline...

16:58 <mosquito520> 2.54" pins... We have some electronic accessory store in Taiwan, but that is expensive in the shop :/

17:00 <mosquito520> usually I'll buy it from the shop, but if I need lot of electronic parts, I'' buy it from taobao, a China C2C website

17:02 <mosquito520> for example... a micro usb connector just need 8.3 cent USD, uh.. 0.083USD

17:02 <mosquito520> It's very cheap :D

17:04 <mosquito520> well~ I got to take a shower and sleep, maybe I can answer some question later, if AstralixNB back:)

17:05 <mosquito520> see yep:_
