05:06 <naobsd> (I'm sorry if you already joined google ml)

05:13 <naobsd> well

05:13 <naobsd> I cannot remember who is "hbfs"...

05:16 <naobsd> and ncrmnt doesn't join long time...

05:24 <naobsd> ah, I found email address for ncrmnt

05:25 <naobsd> no info for hbfs... :(

05:42 <naobsd> I forgot why I'm doing "organize" things

05:43 <naobsd> anyway

05:44 <naobsd> is dl.linux-rockchip.org needed e.g. flashing tools, snapshot images, etc?

05:49 <eebrah> @naobsd: I'd like that

05:53 <naobsd> I see

06:19 <naobsd> https://github.com/linux-rockchip/rkflashtool/commit/6da95a860e856e559310a6d96830eb687c23a132 I pushed mask rom support for rkflashtool

06:20 <naobsd> no wiki, sorry.

06:23 <naobsd> oh, I forgot to fix usage... L is not only for USB loader(usbplug) ;)

06:24 <naobsd> btw

06:24 <naobsd> using stdin/stdout is terrible interface!

06:24 <naobsd> ^I'm the origin

06:36 <naobsd> same for 1 letter command

06:40 <Soopaman> hola naobsd, is the github url you listed the best place to find rk3188 and rk3288 appropriate linux kernels?

06:43 <naobsd> Soopaman: it depends your object. if you need Linux mainline, github/linux-rockchip is not best place.

06:45 <Soopaman> naobsd: other than a linux kernel that I can compile that enables the bluetooth hardware, I'm honestly not even sure where to start given the proliferation of kernel resources and patch "standards"

06:48 <naobsd> Soopaman: https://github.com/linux-rockchip/kernel_rockchip this repo contain up-to-date Rockchip 3.0 based kernel source. and I don't know any other "up-to-date" kernel source/repo

06:50 RayFlower has quit [Read error: Connection reset by peer]

06:50 RayFlower has joined #linux-rockchip

06:51 <Soopaman> do you know which kernel version this is?

07:05 <naobsd> Soopaman: you can get it from Makefile like https://github.com/linux-rockchip/kernel_rockchip/blob/rockchip-3.0-stable/Makefile

07:05 <naobsd> and Rockchip kernel version number is not equal to Linux kernel version number

07:14 <Soopaman> oh

07:14 <Soopaman> heh, just when i thought it was about to make sense :/

12:32 <naobsd> mmind00: thank you very much, and sorry for bothering you

12:32 <mmind00> naobsd: I don't even know who added me to this "owners" group ... wasn't me :-)

12:34 <naobsd> mmind00: first person just added/invited some people to default team "Owner" ;)

12:35 <naobsd> later I also added some people to "Owner" ;)

12:36 <naobsd> and now there is a person I cannot contact ;)

12:37 <naobsd> actually "who is owner" is not so important, what I want is some more public member ;)

12:38 <PaowZ_> about what ? :)

12:38 <naobsd> almost no communication on google-ml, few members on github, it still looks like "dead" community ;)

12:39 <naobsd> PaowZ_: https://github.com/linux-rockchip

12:41 <naobsd> ah, I should add google-ml on here...I have to remember IRC command again ;)

12:46 <PaowZ_> can't find the "follow" button to watch after this community ;)

12:48 <naobsd> PaowZ_: sorry, no idea...

12:48 <PaowZ_> anyway, I "follow" you Naoki ;)

12:48 <PaowZ_> only 3 people..

12:49 <naobsd> ah

12:50 <naobsd> We want people who can lead us :)

12:51 <PaowZ_> you're a leader, aren't you ?

12:51 <PaowZ_> AFAIK, you're the one of the most online person involved into the project..

12:52 <PaowZ_> this shall be sufficient..

12:52 <naobsd> I don't know ;)

12:53 <PaowZ_> (I "watch" each project in the community, instead of entering the people round..)

12:53 GriefNorth has quit [Ping timeout: 244 seconds]

12:54 <naobsd> or should I? but I don't want to bother anyone who are doing his own development work

12:55 <naobsd> (so I have to say sorry to mmind00 several times ;)

12:55 <PaowZ_> what is the trouble, actually, with mmind00 ??

12:56 <naobsd> I mentioned him frequently :)

12:56 <naobsd> ping ping ping ping ...

12:56 <mmind00> naobsd: :-D no need to be sorry

12:57 <PaowZ_> as long as you give credit to his work, I don't get why he should be upset..

12:57 <naobsd> PaowZ_: ah, sorry, no trouble at all

12:57 <naobsd> kind of joke

12:57 <PaowZ_> okay :) soory

12:58 <PaowZ_> If I had the time to propose mods, I'd be glad to take part of it..

12:58 <PaowZ_> I believe this is the best way to get into the kernel stuff and so on..

14:32 <AstralixNB> Funny... my radxa serial port doesn't work here on my notebook, while it works perfectly at home with my workstation.

14:33 <AstralixNB> same usb-serial adapter board at both places

14:38 <naobsd> AstralixNB: some radxa users mentioned it...

14:39 <AstralixNB> There was a modification for the later boards according ESD and over voltage protection. But My adapters work down to 1.2V...

14:50 <hramrach_> once my adaptor did not work and when I disassembled and reassembled everything it miraculously started to work again

15:01 <rperier> mmind00: can you power supply the marsboard through usb ? (like the radxa) or only through the power supply connector ?

15:01 <hramrach_> read their manual/schematic ;-)

15:02 <mmind00> rperier: I run my marsboard though the usb all the time

15:02 <rperier> I am looking for an usb relay to handle the power supply remotely, that's why I am wondering how the marsboard might be powered

15:02 <rperier> mmind00: through the usb otg ?

15:02 <mmind00> rperier: yep

15:02 <rperier> ok perfect, thanks

15:21 <PaowZ_> AstralixNB: mine is just one-way..

15:21 <PaowZ_> I can only receive data from the board but cannot send data, apparently..

15:22 <PaowZ_> so I end up with the console prompt.. no way to log in.

15:23 <AstralixNB> relocate serial port to a pin pair available through the side headers and keep care that you only adapt a USB-serial adapter that is not giving more than 3V3 on any pin.

15:24 <AstralixNB> You probably have caused an ESD shot to the input or got a latch-up by applying to high voltage to the input.

15:24 <PaowZ_> I'm talking about the serial console (FIQ0 ?) we get through the usb cable that ends with 3 wires

15:25 <AstralixNB> There where taken countermeasures against that in newer radxa hardware releases

15:25 <AstralixNB> Yes me too.

15:25 <PaowZ_> ah.. ok..

15:25 <PaowZ_> so you advise me to relocate serial port ??

15:25 <AstralixNB> You can set any other serial port for beeing console. In worst case you might miss some early kernel messages but can use any serial port as a tty

15:25 <PaowZ_> so we leave the 3 debug pins ?

15:27 <AstralixNB> That is at least one option to get full access again

15:27 <PaowZ_> the side headers are GPIO thing ??

15:28 <AstralixNB> With linux kernel it should be enough to check that one of the other serial ports is enabled and you could modify the kernel command line in parameter to use console=/dev/tty[0..x]

15:28 <PaowZ_> wooww.. ^^

15:28 <PaowZ_> fine..

15:28 <AstralixNB> And yes, I was talking of the headers at the side of the PCB

15:29 <PaowZ_> I have to ensure I blew the input, first..

15:30 <PaowZ_> that would be a shame, since I haven't made my RRPro works yet..

15:32 <AstralixNB> Have to leave now. Be back in an hour or so with my alter ego :)

15:49 <hramrach_> hmm, so how do I make a board.c or DT for booting on a board for which no config exists so far?

15:50 <hramrach_> and where do I get SPL or other DDR setup blob?

15:51 <hramrach_> I guess I need a kernel with graphics support

15:54 <hramrach_> I have a lcd and hdmi but no serial

16:06 <mmind00> hramrach_: display support for mainline kernels is still a bit away ... but in general for a dt you would ideally just use one of the available board .dts files as base [as rockchip boards often follow a reference design]

16:07 <mmind00> hramrach_: in mainline land, the kernel config itself and also the whole kernel code is supposed to be board-independent ... so the .dts is the only thing board-specific

16:07 <cristian_c> hi

16:08 <cristian_c> naobsd, is fbset contained in cwm recovery?

16:09 eebrah has joined #linux-rockchip

16:10 <hramrach_> presumably you can just upload it over adb if it is not

16:10 <hramrach_> mmind00: ok, no display rules out mainline then

16:11 <hramrach_> yes, presumably with DT you have all rk devices listed and you just set 'ok' on devices actually present

16:12 <hramrach_> or IPs or whatever
