**** BEGIN LOGGING AT Thu Oct 09 03:00:00 2014 Oct 09 06:27:24 Good morning all, I tried to flash emmc to our cloned bbb board with this BBB-eMMC-flasher-2013.06.20.img. When i apply power after removing SD card. i hang in filesystem check , see log "http://pastebin.com/tyRhQh0r". how to overcome this check? Oct 09 06:29:52 this doesn't look like a fsck, but the try to open something on ttyUSB0 (which fails) Oct 09 06:37:23 letoThe2nd : Am sorry , I copied that log after disconnected debug port thats why its showing "Cannot open /dev/ttyUSB0! Oct 09 06:37:23 " Oct 09 06:43:23 letoThe2nd : Actually it hung up here " systemd-fsck[85]: Angstrom: clean, 48938/112672 files, 272096/449820 blocks Oct 09 06:43:23 " Oct 09 06:43:50 embed: this still doesn#t look like an fsck, just like it doesn't open a getty after that Oct 09 06:58:48 embed, I think systemd doesn't output all boot info to your console, there should be much more of it Oct 09 07:36:11 letoThe2nd & MK_FG : please see this log " http://pastebin.com/tASUbGML " this happen after sometimes Oct 09 07:38:19 embed: no idea what you'Re doing there, sorry (and actually no time to dig deeper here) Oct 09 07:42:07 MK_FG : can you sort out ?? Oct 09 07:43:40 embed, Looks like some kernel bug, maybe worth checking if it might be fixed in newer version (with rcn patches) Oct 09 07:44:24 But there's still no output from systemd boot process, as you'd expect on console, and no journal either Oct 09 07:45:27 embed, Here's what I get on uart - https://ezcrypt.it/5I9n#LS90p7zuZBFlpQ9cjXc8cxx5 Oct 09 07:45:48 (scroll to the end, where systemd stuff starts) Oct 09 07:46:10 I think you might want to look at system.conf and journald.conf in /etc/systemd for how to enable that Oct 09 07:46:29 Or maybe just check out journal in /var/log/journal on sd card Oct 09 07:46:46 (if flush is often enough there) Oct 09 07:46:58 (and enabled at all) Oct 09 07:51:39 MK_FG : SD card boot works fine. But when i flash the same image to emmc am getting this type of log. Oct 09 07:52:03 This log does not show what goes wrong with systemd Oct 09 07:52:32 It'd help *a lot* to see systemd journal or what it outputs to console Oct 09 07:52:33 I got the same log while fusing the same image to SD card Oct 09 07:52:40 Otherwise I've no idea what happens there Oct 09 07:53:08 Read what I wrote above about how to enable (or access) these logs Oct 09 07:53:31 yes i will that follow Oct 09 07:53:48 And if I had to guess, it's probably some entry in your fstab, but again, logs should show it very clearly Oct 09 08:01:27 MK_FG : There are num of variables , all disabled in system.conf and journald.conf , Can you post your conf files?? Oct 09 08:02:58 Mine are pretty much default - all settings there are commented-out Oct 09 08:04:12 I think in my case systemd just shows all that due to some console=* cmdline arg (and starts serial getty there) Oct 09 08:04:22 here is mine "http://pastebin.com/sf0jycph" Oct 09 08:05:06 Also all-defaults in your case Oct 09 08:05:21 MK_FG : yes Oct 09 08:05:37 I'd read up "man journald.conf" on ForwardToKMsg= and ForwardToConsole= Oct 09 08:05:59 Either one seem to be what you might want (what you see in console is kmsg) Oct 09 08:06:30 I couldn't get you MK_FG Oct 09 08:06:46 Which statement? Oct 09 08:07:55 the above last two statement Oct 09 08:08:38 What you see in http://pastebin.com/tASUbGML is kernel log (kmsg) Oct 09 08:09:11 So I'm suggesting you to read up docs on ForwardToKMsg= and ForwardToConsole= options in journald.conf Oct 09 08:10:11 yes, this is clear enough. Oct 09 08:10:19 First one should probably make journal output visible there, in particular, but last one (or figuring out why there's no getty there) might be a better way Oct 09 10:00:31 hi Oct 09 10:15:52 hi, i would like to know how to connect the BBB to the router? as i am new, when i connect the BBB to the router, will it get internet connection automatically? Or do i need to make some settings? Oct 09 10:16:40 no Oct 09 10:16:43 if your router has DHCP server active it will give an IP to the BBB so u will have internet connection Oct 09 10:16:44 just hook it up Oct 09 10:16:52 it should DHCP nicely Oct 09 10:18:52 If "internet connection" would also mean that it's port 22 will be accessible to anyone there, might be a good idea to change root password first ;) Oct 09 10:19:42 I assume a DSL behind a NAT Oct 09 10:27:25 thnx guys, will give a try :) Oct 09 10:51:45 Hi, is there a way to send BBB events to a remote server using javascript? (BBB running Debian) Oct 09 10:53:32 amila: yes Oct 09 10:53:43 amila: js is a programming language like any other Oct 09 10:54:00 amila: you can write all kinds of programs with it, even those that speak to other computers Oct 09 11:01:25 KotH: thanx for ur reply mate. as i am new, is there any tutorial to watch or some important information that i can get? I successfully done with ios push notifications. Now i am trying to send BBB events to our own server and save them to analyze later Oct 09 11:02:46 amila: well.. beside learning how to program and computers in general? Oct 09 11:03:10 amila: maybe you should tackle some easier problem first Oct 09 11:03:36 * KotH misses the times when kids were happy when their transistor circuit blinked a LED Oct 09 11:05:18 koth: no mate i think you didn't get me. I am good at programming, but this is the first time i am dealing with electronics. So i would like to use inbuilt cloud 9 and node js to access a remote server. Thats why i was asking about a tutorial o r smthng. Appriciate your help.cheers Oct 09 11:06:18 amila: the BBB is a computer like your PC until you try to really deal with electronics (ADCs, DACs, motors, relais,..) Oct 09 11:06:35 amila: there is nothing different in programming a networked application on a BBB than on a normal linux PC Oct 09 11:07:15 amila: if you dont feel confortable with cloud9, choose something else. perl, c, java, ocaml, eifel,... Oct 09 11:07:35 koth : il give a try mate, cheers. Oct 09 11:07:40 amila: hint: as long as you write "r u" or "yo mate" or "smthng", people will whink you're a kid that just wants his homework done. using standard english shows (at least a bit) that we are communicating with a person who cares to put thought into what he/she says, instead of just, well... burping up something. Oct 09 11:08:14 LetoThe2nd: i guess amila is in his/her late teens, early tweens... not only from "yo mate" & co Oct 09 11:08:26 hmm... Oct 09 11:08:35 amila: how old are you? if i may ask Oct 09 11:08:40 amila: for the channel statistics ;) Oct 09 11:10:14 amila: and as you are talking about node.js, its api is properly documented here http://nodejs.org/api/ Oct 09 11:10:36 amila: pick you transport mechanism (http, udp, whatever) and start reading up on it. Oct 09 11:11:25 KotH: i didnt think that using chat language will make a differance to the conversation. I am sorry, my bad. I just thought that this is a simple chat service instead of tying all the english words. But I appriciate all your help and suggesions. Btw, i am not a native english speaker. Oct 09 11:12:01 LetoThe2nd : thanks alot. Il search more and il give a try. Cheers Oct 09 11:12:53 ..these words are in no relation to native speaker or not Oct 09 11:13:43 amila: well, the only information we have on you are your written words Oct 09 11:14:00 amila: they suggest a certain image by the choice of words Oct 09 11:14:56 amila: e.g. if you would come and start of with "i have a doubt" i would picture an indian student who has been given some homework with the bbb... Oct 09 11:16:27 amila: an for you personal information, none of the persons that spoke to you today is a native speaker either. Oct 09 11:16:39 amila: alternatively, think what kind of image you'd have of me whenn i aafange wür eso z'rede? würsch überhaupt öbbis verstoh oder würsch eifach denke, dass i nume uf de taschtatur umehau? Oct 09 11:16:56 KotH is a bayer? Oct 09 11:17:04 Humpelstilzchen: are you trying to insult me? Oct 09 11:17:22 do you want an answer ;) Oct 09 11:17:35 KotH: i am sorry if i did a wrong thing mate. i am a student living in united kingdom from Sri Lanka, trying to learn something new. Cheers. May u all reach the ever success in everything you do !!! Oct 09 11:17:55 amila: dont worry about doing things wrong. just learn from them :) Oct 09 11:18:53 as long as there's no blue smoke.. no harm, no foul :) Oct 09 11:20:07 smoking is not permited on these premises Oct 09 15:00:56 Is it possible to change the pinmux without specifying a driver? For ex: http://pastebin.com/r9a32jPQ Oct 09 15:02:47 sheridp: I think mdp or panto might know that Oct 09 15:10:09 sheridp, yes Oct 09 15:11:07 http://roshan.info/blog/2014/03/03/beaglebone-black-pinmux-and-dts-helper/ Oct 09 15:11:31 https://github.com/beagleboard/meta-beagleboard/blob/master/common-bsp/recipes-kernel/linux/linux-mainline-3.8/not-capebus/0100-Pinmux-helper-driver.patch Oct 09 15:12:51 panto: the problem is that it doesn't work, unless I add another fragment with target = <&spi0>; but maybe I just need to target &ocp? Oct 09 15:13:14 err, what? Oct 09 15:13:42 you got to use the pinmux helper driver Oct 09 15:13:45 it's not optional Oct 09 15:13:48 sorry, taking a look at that now Oct 09 15:23:07 panto: it worked! thanks Oct 09 18:08:16 Is there something in the dss(-driver) that lets you clip/clamp the output values? Oct 09 18:08:50 <_av500_> tomba: ^^^ Oct 09 18:09:14 <_av500_> tasslehoff: there is something for full vs restrcited luma for video I think Oct 09 18:10:19 _av500_: interesting. we have a quite vivid gui+video experience, and I'm looking for a way to tone it down a bit. Oct 09 18:12:00 <_av500_> erm Oct 09 18:12:03 <_av500_> by clipping? Oct 09 18:14:55 _av500_: yes. patent pending :p Oct 09 18:15:32 I'm on shaky ground here, but was told to investigate if something like that could be done Oct 09 18:17:22 wonder if the people asking think that audio and video behave the same Oct 09 18:17:32 I want to lower the volume of the video! Oct 09 18:17:45 Well, they *are* eventually waves. Oct 09 18:17:57 But I thyink desaturation is what you are looking for. Oct 09 18:18:43 agmlego: yes. that is what I'm looking for. the IPA has taken my words away. thanks. Oct 09 18:22:48 tasslehoff: maybe tuning the gamma table? Oct 09 18:23:16 not supported in the mainline, though, but I have a patch for that (for omapdrm) Oct 09 18:23:57 tomba: then it can be done through sysfs? I'm on 2.6.39. Oct 09 18:25:02 tasslehoff: well, if you implement sysfs support =) Oct 09 18:25:31 tomba: that could be done :) Oct 09 18:26:11 tasslehoff: setting the gamma table is not that difficult. I don't have the patch with me now, though. but it's basically just writing 256 values to a register. Oct 09 18:27:23 but you say kernel 2.6, which is from the last millenium, so I presume you're using omap1, which doesn't have gamma table ;) Oct 09 18:27:54 tomba: heh, I'm on omap3 Oct 09 18:28:16 the 3530. had to stay at 2.6.39 because of power management. Oct 09 18:29:22 haven't found a sweet spot with working suspend and graphics drivers beyond that version Oct 09 18:31:03 I think my last omap3 device died some time ago, so I can't even test those anymore Oct 09 18:31:47 tomba: buy a lg p970. omap3 based, very cool phone Oct 09 18:32:12 tomba: but I should have a gamma table there I hope? Oct 09 18:33:14 tasslehoff: yes, I'm 99% sure omap3 had gamma table. it should be trivial to create a sysfs/debugfs file, and a function which writes the values to the gamma register. presuming you have some kernel coding knowledge. Oct 09 18:33:57 tomba: yes, I don't think that will be hard. thanks. Oct 09 18:34:52 I can send you my patch tomorrow, if you want. just send me an email to tomi.valkeinen@ti.com, and I'll reply to that when I'm at office. Oct 09 18:35:48 thanks a lot! Oct 09 18:36:25 I'm seeing a very strange behavior when I set PIN34 of MODULCTRL for the MC_SPI0. With this bit set, the CLK no longer toggles, but according to the TRM, PIN34 should not affect SCLK Oct 09 18:37:26 <_av500_> tasslehoff: tomba: ah right, gamma ray table Oct 09 18:37:33 <_av500_> omap3 has been so long ago :) Oct 09 18:39:03 _av500_: lucky you. Oct 09 18:39:07 <_av500_> :) Oct 09 18:39:09 I'm still stuck :) Oct 09 18:39:19 Now I have to listen to gamma ray Oct 09 18:39:21 <_av500_> tasslehoff: sometimes I wish I could go back Oct 09 18:42:11 _av500_: I hope to get to the place where I can wish that too Oct 09 19:09:01 _av500_: just buy a moto360 and you'll be back in the OMAP3 days Oct 09 19:10:52 <_av500_> right Oct 09 19:11:11 <_av500_> port the video player Oct 09 19:11:27 avos on moto360! Oct 09 19:11:36 <_av500_> yep Oct 09 19:11:48 libav500? Oct 09 19:44:24 hello Oct 09 19:45:55 moo Oct 09 19:50:40 Does somebedy can help me with me bb xm rev c Oct 09 19:52:11 maybe... if you're more specific Oct 09 19:52:56 hello thurgood Oct 09 19:53:15 have u installed ubuntu on you bb xm rev c Oct 09 19:53:51 no, but I image rcn-ee has Oct 09 19:54:17 don't think he's here at the moment though Oct 09 19:54:56 still no real question though... Oct 09 19:54:59 i didnt get it ,, rcn-ee is a user or a webpage,, sorry Oct 09 19:55:37 well mi question is, If you have solve the resolution problem on de Envr.txt file Oct 09 19:55:38 user, aka Robert C Nelson Oct 09 19:56:00 when you are using ubuntu Oct 09 19:56:01 what's "the resoultion problem"? Oct 09 19:56:21 i can not get it,, what it´s the problem Oct 09 19:56:30 uEnv.txt? Oct 09 19:56:36 yeah Oct 09 19:56:51 what is your current setting? Oct 09 19:57:03 and what are you trying to set it to? Oct 09 19:57:06 sorry for my low write Oct 09 19:57:32 i´m from colombia so i have think in spanish then traslate to english Oct 09 19:58:31 mi current setting is 1280x1024 Oct 09 19:59:02 and i´ve tried all resolutions in blogs Oct 09 19:59:10 but nothing happend Oct 09 19:59:23 always the same ghost screen Oct 09 19:59:28 is your aspect ratio 4:3 ? Oct 09 19:59:38 umm Oct 09 19:59:53 on the monitor itself Oct 09 19:59:54 you have to set the ratio too?? Oct 09 20:00:15 i´m using a hdmi cable Oct 09 20:00:25 1280x1024 is a 4:3 ratio Oct 09 20:00:56 not extremely common anymore, but still possible Oct 09 20:01:16 ohh men,, i´m working right now, and found this group Oct 09 20:01:35 i don´t have my sd card here Oct 09 20:01:49 no worries we'll be here later :P Oct 09 20:02:15 when are u connected again, Oct 09 20:02:44 by the way, do you have a usb-serial connection ? Oct 09 20:02:58 but this is a official blog for the bb Oct 09 20:03:08 most of the day Oct 09 20:03:34 thurgood you are so nice,, thank for find me Oct 09 20:03:46 about as official as it gets, most people are using the beaglebone black these days Oct 09 20:04:18 when i have my sd card next to me. Oct 09 20:04:29 i´ll connnect again Oct 09 20:04:32 ok Oct 09 20:04:50 or could you please give your email Oct 09 20:05:43 no, I don't do email support... but someone will likely be around when you reconnect Oct 09 20:06:21 ok, thank u again.. finally some help Oct 09 20:06:23 bye Oct 09 20:10:08 jpic1212 is gone. how sad Oct 09 20:13:13 Does anyone know of an IRC chat for Sitara processors, or is this the best venue for that? Oct 09 20:13:59 Sitara is ARM. Oct 09 20:14:32 sheridp there is none as far as I know Oct 09 20:15:16 Find an ARM-compiled IRC client that runs on your ARM-compiled OS. Oct 09 20:15:16 THere is probably a binary for irssi by now in the debian repos for armhf. Oct 09 20:15:42 agmlego he did not use the term client Oct 09 20:16:08 <_av500_> sheridp: the best place is TI e2e forums Oct 09 20:16:15 <_av500_> if you are a professional Oct 09 20:16:24 Nope, but since an "IRC chat " is not a thing...I made a reasonable assumption. Oct 09 20:16:39 <_av500_> it is a thing for some :) Oct 09 20:16:46 But the point still stands--unreal probably crosscompiles OK. Oct 09 20:16:53 I think netflix has to be the worst thing ever :( Oct 09 20:17:28 Jonnyw2k-home wait what? Oct 09 20:18:00 When I was younger I used to be quite productive, and eager to learn Oct 09 20:18:08 these days I just sit here watching netflix Oct 09 20:18:29 And telling others about it in an of-topic way on IRC. Oct 09 20:19:48 It was kinda a wrong channel kind of thing, but someone asked before I realised Oct 09 21:07:56 agmlego: sorry I did mean channel, not client Oct 09 21:08:20 sheridp: So you want an IRC *server*. Oct 09 21:08:32 _av500_: thanks for the e2e info Oct 09 21:08:38 Like Unreal or ircd Oct 09 21:09:11 yeah I'm not exactly hip on the IRC lingo, but essentially like the #beagle channel but specifically for TI processors Oct 09 21:10:30 oh, sorry, no not a server or a client, but a location in which others are discussing the processor Oct 09 21:10:40 So channels are served up by servers. Oct 09 21:10:44 Oh. Oct 09 21:10:51 You are not looking for software. Oct 09 21:10:59 right Oct 09 21:11:00 YOu are looking for a discussion forum. Oct 09 21:11:09 Yup,. e2e. Oct 09 21:11:44 I know of no TI-specific IRC channel on any network. Oct 09 21:11:50 Just out of curiosity, are most people here professionals? Oct 09 21:13:07 No. Oct 09 21:13:09 Yes. Oct 09 21:13:10 Maybe. Oct 09 21:13:31 Probably most people here are employed, and thus professionals at whatever it is they are paid to do. Oct 09 21:15:13 I suppose, but what I meant was professional developers / embedded systems designers; not professsional swing dancers who have a hobby of using the beagle boards Oct 09 21:15:53 In that case, no, most are hobbyists or worse. Oct 09 21:18:25 I see; right now I'm a graduate student and am trying to get an idea of what the corporate world of embedded system development is really like Oct 09 21:19:37 sheridp uhm uh Oct 09 21:21:51 like programming in general, with less available resources :P Oct 09 21:24:58 ^^^ Oct 09 21:25:12 sheridp: THis is what internships and co-ops are for. Oct 09 21:26:50 agmlego ah thanks internship was the word Oct 09 21:27:01 * djlewis is professionally unprofessional Oct 09 21:27:32 its an acquired art Oct 09 21:36:56 So, I've finally found the source of my problems, but I still don't understand the why: Setting PIN34 in MODULCTRL causes the MCSPI not to transmit; any ideas why? Oct 09 21:37:13 (same thing if setting SINGLE) **** BEGIN LOGGING AT Fri Oct 10 00:03:14 2014 Oct 10 02:37:02 hello some expert in the room Oct 10 02:37:26 "never ask to ask, just ask" Oct 10 02:37:41 jejeje thank u agmlego Oct 10 02:38:06 i have a bb xm rev c , and i tried to install ubuntu 14 Oct 10 02:39:15 i made all steps ok, install de OS in sdcard and turn on in the BB and i get a ghost screen Oct 10 02:39:37 i barely can see asking for login> Oct 10 02:39:52 but it's impossible to see Oct 10 02:40:30 also i have tried to change the resolution but i really desperate with this stuff Oct 10 02:40:57 can somebody help me with this Oct 10 02:42:05 thurgood are u there_ Oct 10 02:42:21 have you had it work at any resolution? Oct 10 02:44:25 when i bought the BB it came with the sd card with angstrom, i turn on , connect the hdmi cable and works fine Oct 10 02:45:01 but with ubuntu i get no pass from the login black screen Oct 10 02:46:34 with angstrom works with 720p 60hz Oct 10 02:47:04 i've tried the same resolution but nothing Oct 10 02:48:13 so maybe it's the way the card was setup, rather than the resolution Oct 10 02:48:24 do you have a usb-serial connection? Oct 10 02:49:48 no, there is no more connected than the power, sdcard and hdmi cable Oct 10 02:50:15 sorry and keyboard and mouse Oct 10 02:51:00 did you follow a tutorial on setting up the card? Oct 10 02:51:19 yes, on internet Oct 10 02:51:33 the web page is let me see my historial Oct 10 02:51:42 what's the link? Oct 10 02:52:04 http://leonvr.blogspot.com/p/blog-page_5.html Oct 10 02:52:08 and Oct 10 02:52:32 http://wlbeagleboard.wordpress.com/2014/07/27/installing-ubuntu-14-04-on-beagleboard-xm/ Oct 10 02:53:06 in all this tutorials always talk about some file called QUANTAL Oct 10 02:53:22 but there is no such a file in the webpage Oct 10 02:53:41 should I buy an element14 beagleboard? Oct 10 02:53:46 beaglebone black Oct 10 02:54:17 thurgood can u recommend me a better tutorial to install ubuntu, i'm really desperate Oct 10 02:54:39 I read some not so good things about element 14's beaglebone Oct 10 02:54:49 no, I've never tried ubuntu, on the xM personally Oct 10 02:56:00 did you put MLO and uboot on the boot partition Oct 10 02:56:16 the tutorial does not seem to mention the bootloaders Oct 10 02:56:25 umm what are those Oct 10 02:56:41 ... yeah Oct 10 02:57:08 MLO is the first loader, which hands off to uboot, which starts up the kernel Oct 10 02:57:30 strukturalna: I was unaware that element14 was still offering their own version. Last I saw, that product had vanished from the Internet. Oct 10 02:57:54 i'm looking in my sdcard and there is a MLO file Oct 10 02:58:04 what i have to do. Oct 10 02:58:11 some change in the file Oct 10 02:58:16 agmlego element 14 started producing a clone because the original company cannot produce enough Oct 10 02:58:19 is uboot.bin there too? Oct 10 02:58:27 it's apparently an 'official' clone Oct 10 02:58:34 not sure what an official clone could mean **** ENDING LOGGING AT Fri Oct 10 02:59:59 2014
