00:23 <naobsd> at office now... let's read log

00:23 <naobsd> btw I will be busy this week and I have to restore git repos at first :(

00:28 <naobsd> I saw some message about high/low voltage...is 3.1v/2.5v normal??? how about gpios?

00:44 <naobsd> akaizen: dev board with source code and schematic is good

00:51 <naobsd> Astralix1: when you mentioned something that you're not sure, please say "i guess" "I'm not sure" etc. you mentioned some things as if the fact (even if you didn't say "in fact"), field^Mop seemed to get some wrong input from discussion with you

00:53 <naobsd> can you tell me any example about rk31xxnand_ko.ko.*? for rk3188, all I have is only rk30xx

00:54 <naobsd> and SoC generic rknand_ko.ko.* too

00:54 <naobsd> and please point the code which does "The Linux kernel modified by RockChip will first try to load a SoC and Linux kernel version generic rknand_ko.ko module. If this fails it tries next the generic module name with the kernel version appended: rknand_ko.ko.<kVer>."

00:58 <naobsd> field^Mop: about "the note at the top about the source of information", all links are not original input. if there is any valuable input, can you point exact URI about it? I cannot find anything because those links point top page of forum/wiki/blog

01:25 <hramrach_> ok, so now I give you a bug report. you have a bug in rkflashtool. please fix it :>

01:26 <hramrach_> it's in one of your changes to the tool, of course :>

02:19 <naobsd> (just asking, I don't have anything yet)

02:19 <ganbold_> so they may offer?

02:21 <naobsd> no idea now, I'm just asking

02:38 <Tony_> who want to know a lot about ubuntu on rockchip.

02:38 <Tony_> I can talk with you. ;P

02:40 <Tony_> naobsd, I have a question about Audio.

02:41 <Tony_> naobsd, Is it likes Internet of Android kernel ?

02:41 <Tony_> naobsd, non root can't aplay some thing.

02:42 <Tony_> naobsd, It can works fine my host Ubuntu.

02:42 <Tony_> aplay /usr/share/sounds/speech-dispatcher/test.wav

02:42 <Tony_> non root account.

02:44 <Tony_> naobsd, need i join "audio" group ? but I have not join "audio" on my host ubuntu.

03:01 <akaizen> naobsd: cool. what do you think about the stability of the board

03:03 <naobsd> Tony_: what error did you get?

03:05 <naobsd> akaizen: stability of what? hardware is running, I don't use stock firmware so much

03:05 <akaizen> what do you use regularly?

03:05 <akaizen> im guessing ubuntu?

03:05 <akaizen> wondering how you feel about the stability and performance with whatever you use regularly

03:06 <Tony_> naobsd, can't play Music with GUI such as GNOME MPlayer or Audacious.

03:07 <Tony_> naobsd, the progress bar don't move.

03:09 <Tony_> from /var/log/syslog

03:14 <naobsd> akaizen: most frequently used should be rkflashtool and reset button...

03:14 <naobsd> akaizen: I have no regular use

03:14 <naobsd> akaizen: probably I'll use it as ubuntu desktop machine

03:15 <naobsd> akaizen: and some kind of "server" with mainline kernel

03:15 <akaizen> ok. trying to figure out how stable it is and what features are available

03:15 <naobsd> Tony_: sorry, I have no idea. I got some trouble with pulseaudio on RR

03:15 <akaizen> mine should be arriving this week

03:15 <Tony_> naobsd, after all. I can play music(mp3/wav) from command such as madplay.

03:17 <Tony_> naobsd, is pulseaudio problem ?

03:18 <naobsd> Tony_: no idea about your configuration, may be, may not be

03:20 <Tony_> naobsd, you can't play music on RR too ?

13:43 <rperier> so , electrically, it works

13:43 <rperier> I have something on TX

13:43 <rperier> the voltage level is at 3.16V

13:44 <rperier> and it did work on my friend's laptop... I think that it's a stability issue with the USBTTL converter

13:57 <rperier> and... it works here too...

13:57 <rperier> I think that my USBTTL converter is a bu***it :D

16:19 <hramrach_> hello

16:19 <hramrach_> do you have source for the kernel you are running on your device?

16:19 field^Mop has joined #linux-rockchip

16:19 <hramrach_> hello

16:19 <neyder_> no idon't

16:20 <hramrach_> then I cannot help you. you need the source.

16:20 <neyder_> but it runs acceptable with linuxium

16:20 <neyder_> one

16:20 <neyder_> only need to activate wireless and ethernet

16:21 <hramrach_> ok

16:21 <hramrach_> actually, it might be because you have wrong source that the devices don't work

16:21 <neyder_> WLAN: RTL8188 LAN: RTL8201F

16:24 <hramrach_> there are multiple linuxium kernel sources. what exactly did you use?

16:24 <neyder_> for the radxa rock (i'm using the pre-made sdcard images)

16:26 <hramrach_> yes, 8188 is disabled

16:26 <hramrach_> https://github.com/linuxium/rockchips-kk/blob/master/.config#L1273

16:28 <hramrach_> did you look here? http://www.linux-rockchip.info/mw/index.php?title=Building_Kernel_for_Linux_Distribution

16:28 <neyder_> yes I do but i cant enable 888188 in there so can't compile ata ll

16:29 <hramrach_> why can't you enable it?

16:31 <neyder_> make menuconfig and only let me enable one

16:35 <hramrach_> when you delete the line that says 8188 and rebuild the kernel it should ask you if you want to build it. say m

20:36 <Astralix> hey, rperier

20:38 <rperier> hi

20:39 <Astralix> Had a short duiscussion about the debug port circuitry with my colleagues...

20:39 <Astralix> Not so happy with the implemented solution and I will measure some details on my defective rock preview board.

20:58 <Astralix> So, I checked my boards and can say, that the original preview rock1 from 08/2013 do not have any protection circuitry at all, besides two diodes.

20:59 <Astralix> The rock pro features an additional FET that protects the TX output and works as a level shifter.

21:00 <Astralix> I was tricked by the schematics. There are two preview versions and one already has the protection, but the first one does not. So I was wondering where the parts are, that are mentioned in the schematics.

21:01 <Astralix> So early preview doesn't have FET, if TX is dead, it is may be dead in the SOC. But I'll check the diode the next days.

21:01 <Astralix> But good to hear, that your board is again talking to you
