**** BEGIN LOGGING AT Wed Jan 28 02:59:59 2015
Jan 28 03:29:38 <ocamlman> anyone have ideas about my GPIO problem?
Jan 28 08:29:25 <tars_> how to download scipy and matplotlib on BBB having debian , anyone ?
Jan 28 08:32:05 <tars_> ^^ anyone ?
Jan 28 08:32:09 <tbr> that's a simple debian question and doesn't have anything specific to the BBB.
Jan 28 08:49:26 <veremit`AFK> apt-get maybe?
Jan 28 09:15:13 <cityoflights2> does anyone have a gEDA layout of the beaglebone black?
Jan 28 09:16:14 <cityoflights2> I had the footprint for the the two double pin connectors, but I also need a layout with the Ethernet connector
Jan 28 11:21:27 <vmayoral> hi everyone
Jan 28 11:21:46 <vmayoral> does anyone knows if it's possible to load dtb files in the bootloader without capemgr support?
Jan 28 11:24:57 <cityoflights2> which kernel are you using (uname -a)
Jan 28 11:30:53 <akhil> hai
Jan 28 11:39:00 <asac> panto: so in ubuntu-core #snappy channel we were discussing how to best realize overlay dtbs
Jan 28 11:39:16 <panto> asac, ok
Jan 28 11:39:24 <asac> we have a feature built in that allows oems and appliance makers to provide their own dtb
Jan 28 11:39:43 <asac> but dont provide their own kernel... and hence we wondered if
Jan 28 11:40:02 <asac> we can combine overlay dtbs with the generic dtb for beaglebone that we produce
Jan 28 11:40:14 <asac> or if not that if u-boot has a built in feature to load overlay dtbs
Jan 28 11:40:27 <asac> or what other options we have given that capemgr isnt upstream etc.
Jan 28 11:41:15 <asac> panto: thoughts?
Jan 28 11:41:26 <asac> if none that's fine.
Jan 28 11:41:27 <asac> :)
Jan 28 11:42:08 <panto> don't do overlays on the bootloader
Jan 28 11:42:26 <panto> the capemanager, or something similar, I will update when 3.19 is out
Jan 28 11:42:27 <asac> ok so that leaves us only with runtime loading and pre-building the right dtb
Jan 28 11:42:34 <panto> don't do that either ;)
Jan 28 11:42:43 <asac> runtime loading?>
Jan 28 11:42:52 <asac> or prebuilding the right dtb for the appliance?
Jan 28 11:43:02 <panto> ok, let's take it from the top
Jan 28 11:43:06 <asac> :)
Jan 28 11:43:07 <asac> thanks!
Jan 28 11:43:16 <panto> the overlays is a generic mechanism
Jan 28 11:43:22 <cityoflights2> ok,,
Jan 28 11:43:41 <panto> other parts of the kernel can use it to build 'things' with it
Jan 28 11:43:55 <panto> one 'thing' is/was the capemanager idea on the beaglebone
Jan 28 11:44:16 <panto> another is some kind of generic board revision control
Jan 28 11:45:10 <panto> what the problem is with device tree and devices is the need to lug along a different dtb for each different device/revision combo out there
Jan 28 11:45:32 <panto> which is pretty cumbersome for generic distributions and end user support in general
Jan 28 11:46:33 <panto> for instance having the end user fiddling bits in the bootloader to make it point to the right dtb is a recipe for disaster
Jan 28 11:47:12 <panto> if I understand correctly your problem is that you want to do a ubuntu release for 'appliances'
Jan 28 11:47:24 <panto> that lies at the realm of board revision control
Jan 28 11:47:47 <panto> I will address that use-case in an RFC patch I'll release shortly
Jan 28 11:47:54 <panto> (maybe today or tomorrow)
Jan 28 11:48:44 <panto> the idea is that instead of having a different dtb for each different board revision, you'll have a single dtb which will include the revision information as overlays in the base tree
Jan 28 11:49:12 <panto> think of it as quirks for device tree, that get applied automatically
Jan 28 11:49:53 <panto> now for optional hardware blocks like the beaglebone capes we'll do something similar to the capemgr
Jan 28 11:50:04 <panto> asac, are you following?
Jan 28 11:50:05 <cityoflights2> you mean that once I read from the ADC it will magically appear?
Jan 28 11:50:11 <cityoflights2> and udev will load it?
Jan 28 11:50:26 <panto> cityoflights2, are you talking to me?
Jan 28 11:50:40 <cityoflights2> yes, I am listening to what you where saying
Jan 28 11:51:00 <cityoflights2> will the device tree move to a dynamic approch?
Jan 28 11:51:01 <asac> panto: so our way of thinking is to give appliannce builder some way to enble their board modifications
Jan 28 11:51:06 <asac> without having to maintain their very own kernel...
Jan 28 11:51:20 <asac> panto: the new snappy ubuntu core world
Jan 28 11:51:29 <panto> yes
Jan 28 11:51:39 <asac> aims to offer official means to enable all types of ecosystem participants
Jan 28 11:51:46 <asac> one of them is those that do the appliances and release products
Jan 28 11:51:50 <panto> if you have a way to identify the model/revision of the appliance it will just work
Jan 28 11:52:04 <asac> so we have a build in feature for the idealistic case where you just need dtb do those modifications
Jan 28 11:52:44 <asac> panto: its in the end the manufacturer who preinstalls the right oem part at factory process that would ship the right dtbs
Jan 28 11:52:55 <asac> and they can update that part pretty easily by directly uploading etc.
Jan 28 11:53:13 <panto> yes, but you need to support that as part of your updates/standard distro release
Jan 28 11:53:53 <asac> panto: support in which sense?
Jan 28 11:53:57 <asac> you mean lockstep?
Jan 28 11:54:17 <panto> let's say you update the kernel in the device
Jan 28 11:54:25 <asac> right
Jan 28 11:54:41 <panto> the kernel-dt deb will include all the applicable dtbs/dtb fragments
Jan 28 11:56:01 <panto> the dtb fragments that contain the hardware configuration for a particular appliance are not standalone
Jan 28 11:56:24 <panto> they are meant to be resolved against the base dtb of the booting kernel
Jan 28 11:57:21 <asac> panto: right so for overlay binary case you need to have exact lockstep. is the same true for dts?
Jan 28 11:57:23 <vmayoral> @cityoflights2 never replied, sorry. We are trying to figure out if it's possible to do so with mainline kernels (with a few patches that ubuntu core kernels require)
Jan 28 11:57:33 <asac> panto: i heard that at least for a single dtb the idea is that it continue working on upgrade
Jan 28 11:57:52 <panto> right
Jan 28 11:58:11 <panto> it is conceivable that you might get by without lockstep, but it's tricky
Jan 28 11:58:29 <panto> especially if you rely on hardware manufacturers to get it right
Jan 28 11:58:34 <panto> (they won't)
Jan 28 11:58:46 <asac> get what right? building the dtb?
Jan 28 11:58:57 <panto> bundling the correct dtb
Jan 28 11:58:58 <asac> i know theyw ill get it wrong for their BSP kernels
Jan 28 11:59:44 <panto> you need to always have a dtb fragment that's built in such a way that it will work on any up-revved kernel
Jan 28 12:00:11 <panto> while with lockstep, you just build every time you update the kernel
Jan 28 12:03:53 <panto> and please note, that if you even think of doing a vendor kernel instead of mainline, I guarantee you that the DT binding won't match
Jan 28 12:04:10 <panto> so binary dtb overlay for that case is impossible
Jan 28 12:04:14 <asac> right
Jan 28 12:04:21 <asac> vendor kernels are not part of the story i try to solve here
Jan 28 12:04:24 <asac> they have a separate story
Jan 28 12:04:38 <asac> this is really about solving the most idealistic casees where folks can use generic kernel
Jan 28 12:04:54 <asac> and just want to do some board modifications that also can be done with all generic modules/drivers etc.
Jan 28 12:05:18 <asac> hey ppisati :)
Jan 28 12:06:26 <asac> ppisati: http://paste.ubuntu.com/9916223/
Jan 28 12:06:26 <panto> if you want I can CC you on the patches when I post them
Jan 28 12:06:28 <asac> the log
Jan 28 12:06:45 <asac> panto: what are those patches about?
Jan 28 12:07:10 <panto> implementing something like the new capemgr/revision functions
Jan 28 12:07:55 <asac> panto: i think ppisati mentioned that upstream has something like overlaydtb now in 3.19?
Jan 28 12:08:25 <panto> yes, overlays will be included in 3.19
Jan 28 12:08:44 <panto> but that's the core kernel functionality, not the end user one
Jan 28 12:11:56 <ppisati> panto: are those patches a new capemgr using the OF_OVERLAY in 3.19, am i getting it right?
Jan 28 12:12:24 <panto> sort of, yeah
Jan 28 12:12:42 <panto> it's going to be an RFC because we'll have to talk about a lot of things that we need to get right
Jan 28 12:12:51 <ppisati> panto: oh, ok
Jan 28 12:13:07 <panto> you're not the only ones that need something like this
Jan 28 12:13:21 <ppisati> panto: last question: can i use a dtb fragment that was working with capemgr with this mechanism?
Jan 28 12:13:56 <panto> ppisati, I aim for this
Jan 28 12:14:04 <ppisati> panto: nice
Jan 28 12:14:12 <panto> the syntax of the overlays hasn't changed
Jan 28 12:14:23 <panto> but I don't know if some details will have to change
Jan 28 12:14:42 <ppisati> panto: i'll keep an eye on lkml for your rfc then
Jan 28 12:14:44 <panto> it's open source stuff - chaos reigns ;)
Jan 28 12:15:06 <ppisati> panto: chaos, long revisioning, etcetc :)
Jan 28 15:20:00 <David_____> ola
Jan 28 15:20:08 <David_____> alguem em portugues
Jan 28 15:20:54 <David_____> I need help
Jan 28 15:30:23 <cooper_> hi i am
Jan 28 15:32:40 <av500> you are
Jan 28 15:32:58 <cooper_> hi i have just plugged in my new beaglebone black and not able to update the os , debian , as soon as i write the command apt-get update , it gives a series of error
Jan 28 15:33:27 <cooper_> Err http://debian.beagleboard.org wheezy-bbb Release.gpg   Could not resolve 'debian.beagleboard.org' Err http://security.debian.org wheezy/updates Release.gpg   Could not resolve 'security.debian.org' Err http://ftp.us.debian.org wheezy Release.gpg   Could not resolve 'ftp.us.debian.org' Err http://ftp.us.debian.org wheezy-updates Release.gpg   Could not resolve 'ftp.us.debian.org'
Jan 28 15:34:12 <cooper_> any help would be appreciated !!
Jan 28 15:34:14 <LetoThe2nd> cooper_: well probably the bbb just has no internet connection.
Jan 28 15:34:35 <cooper_> i have connected it via USB
Jan 28 15:35:18 <LetoThe2nd> cooper_: i doubt that your laptop, without further measures, is bridging its network connection to the virtual ethernet over usb. so that is by good chances your problem.
Jan 28 15:37:34 <cooper_> it might be a silly alternative but if i connect my BBB with ethernet and operate via USB , would that work ? QLETO
Jan 28 15:38:07 <LetoThe2nd> cooper_: probably.
Jan 28 15:38:51 <LetoThe2nd> although i have no idea what a QLETO is. OLED-O? QWERTO?
Jan 28 15:38:58 <Trouyan> Hello. All LEDs o my BBB are off. If I plug power, pwr LED flashing one time and switch off.... rev A. Somebody know how to solve this problem ?
Jan 28 15:41:25 <Trouyan> And most interesting is that I have ping between BBB and host, but I can't login to BBB, paswords wrong, but I didn't change it.
Jan 28 15:42:55 <cooper_> thanks a lot @leto , it worked !! :D
Jan 28 16:03:22 <Guest79758> Is anyone active in here?
Jan 28 16:03:33 <Trouyan> yes I am
Jan 28 16:03:53 <karki__> no, we all are on standby mode.
Jan 28 16:04:10 <Trouyan> =)
Jan 28 16:04:38 <Guest79758> Oh ok. Well I was looking for some help on a beaglebone black rev c boot issue.
Jan 28 16:05:13 <Trouyan> I'm too looking some for help me )))
Jan 28 16:05:40 <Trouyan> but with BBB rev A
Jan 28 16:06:19 <Guest79758> Well I'm probably not in any position to help, sorry...
Jan 28 16:07:10 <av500> ask, dont ask to ask
Jan 28 16:07:59 <Trouyan>  All LEDs o my BBB are off. If I plug power, pwr LED flashing one time and switch off.... rev A. Somebody know how to solve this problem ?
Jan 28 16:08:48 <Trouyan> If push Power Button, PWR LED flash again,
Jan 28 16:13:32 <av500> reflash it
Jan 28 16:13:43 <av500> get an sd card and follow the instruction to flash the board
Jan 28 16:13:49 <av500> or just boot from SD for a test
Jan 28 16:15:23 <Trouyan> I've  tried update software (by instructions) , but all LED still off
Jan 28 16:20:31 <Guest79758> My problem is I have 2 BBB rev c's, one running Ubuntu and the other running the pre-installed Debian. On about 1/10 reboots the board will not boot, only the power led comes on.
Jan 28 16:21:21 <Guest79758> And sometimes when the board does boot, the ethernet port is not detected on boot. So I have to reboot to fix that problem.
Jan 28 16:22:45 <Guest79758> I have done a lot of research and found it has something to do with the board going into u-boot. Apparently you can recompile the MLO and u-boot.img files and this is suppose to fix it.
Jan 28 16:23:25 <Guest79758> But I must not be doing something correct because it doesnt help my problem.
Jan 28 17:09:22 <weresquid> Is there any way you can connect the Beaglebone Black to this (http://www.clientop.com/products_pic/201352215343429481.jpg) through the GPIO pins?
Jan 28 17:19:22 <DarkShymia> Boa tarde
Jan 28 18:34:03 <Sangu143> hi
Jan 28 18:34:25 <ocamlman> hi
Jan 28 18:34:56 <Sangu143> wanna know how to intrface headphone to BB black??????
Jan 28 18:35:06 <Sangu143> ny1 help?
Jan 28 18:35:20 <stt_michael> u need a sound card
Jan 28 18:35:47 <Sangu143> i wanna audio output frm BBB
Jan 28 18:35:58 <Sangu143> how can I?
Jan 28 18:36:16 <ocamlman> does the HDMI have audio channels?
Jan 28 18:36:22 <ocamlman> if so, you can use something like this: http://www.knoxed.com/luxi/hdmi-audio-extractor/
Jan 28 18:37:06 <Sangu143> can I using USB?
Jan 28 18:37:15 <ocamlman> http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2013/05/28/bbb--audio-notes
Jan 28 18:38:40 <Sangu143> thanx
Jan 28 18:38:51 <Sangu143> it may helpful
Jan 28 18:39:40 <stt_michael> usb is easier . I think there is a serial bus for audio also available if you want to go hard-core
Jan 28 18:42:18 <Sangu143> ohhh...
Jan 28 18:42:19 <Sangu143> kk
Jan 28 18:44:41 <Sangu143> i also wanna interface USB web cam as input
Jan 28 18:45:37 <Sangu143> can I connect both sound card and usb webcam to same port?
Jan 28 18:46:08 <stt_michael> you're going to want a usb hub I suspect .. the next thinig you're gonna say is wifi isn't it ?! :p
Jan 28 18:46:38 <Sangu143> nope
Jan 28 18:47:13 <Sangu143> :D only web cam and audio
Jan 28 18:47:15 <stt_michael> heh ok
Jan 28 18:48:47 <Sangu143> but can I interface both at a time? one as input and another as output?
Jan 28 18:49:09 <stt_michael> of course - they are client devices
Jan 28 18:49:54 <Sangu143> ok..... thanx, if u dont mind can I get ur mail id? if i need further help
Jan 28 18:50:11 <thurgood_> lol
Jan 28 18:50:28 <Irvin_> How i enable a web server or service so i can use php with mysql?
Jan 28 18:50:33 <stt_michael> I suggest you revisit this room .. plenty of advice here
Jan 28 18:50:46 <stt_michael> Irvin_: you've installed your LAMP stack?
Jan 28 18:51:03 <stt_michael> ie . linux, apache (or else), php and mysql ?
Jan 28 18:51:10 <Shadyman> GET LAMP
Jan 28 18:51:11 <Irvin_> yes
Jan 28 18:51:23 <stt_michael> if you're using debian, it should have configured itself
Jan 28 18:51:38 <Irvin_> yes, is debian
Jan 28 18:51:40 <stt_michael> apache will likely autostart
Jan 28 18:51:59 <stt_michael> so just go to the web interface .. check for the start page .. you can then copy php test pages, and off you go
Jan 28 18:52:05 <stt_michael> you may fine phpMyAdmin useful
Jan 28 18:52:21 <stt_michael> s/fine/find
Jan 28 18:53:47 <Irvin_> done that, the issue comes when i call a php page to insert data to mysql, and have a error saying that i can't post, i search on internet and was related to web server not running or installed
Jan 28 18:54:49 <thurgood_> did you install php with apt-get?
Jan 28 18:55:13 <stt_michael> you may need to load the php module in apache
Jan 28 18:55:34 <thurgood_> apt-get should handle that apache/php configuration
Jan 28 18:55:53 <stt_michael> "should" :) depends on the order of installation I suspect
Jan 28 18:55:55 <Irvin_> yes i used sudo
Jan 28 18:56:17 <Irvin_> ok, i will reinstall everything
Jan 28 18:56:37 <thurgood_> and you put your pages in the webroot?
Jan 28 18:57:48 <thurgood_> you cannot call php from arbitrary locations., unless you configure it to do that (which you shouldn't)
Jan 28 18:58:37 <Irvin_> yes, it was on the root location, they are running fine, the problem comes when i call php
Jan 28 18:59:35 <thurgood_> kinda guessing in the dark as I don't know what steps yo uactually took
Jan 28 19:01:03 <Irvin_> i will start from the begining to see how it works
Jan 28 19:01:07 <stt_michael> pastebin what comes in the browser ..
Jan 28 19:01:25 <stt_michael> or .. wherever you#'re getting an error/msg
Jan 28 19:01:43 <stt_michael> it can be also instructive to check the apache logs in /var/log/apache or similar
Jan 28 19:02:09 <thurgood_> or the relevant error log portions
Jan 28 19:02:30 <stt_michael> and/or pastebin from the logs too ;)
Jan 28 21:48:20 <cityLights> does anyone here use gEDA?
Jan 28 21:48:49 <cityLights> I seek a layout of a bealebone black for geda, including the ethernet port
Jan 28 21:49:12 <stt_michael> lol
Jan 28 21:49:14 <cityLights> I only have the two dual pin connectors
Jan 28 21:49:30 <stt_michael> do you mean a shield .. not the whole board?
Jan 28 21:49:37 <cityLights> eagle has a nice layout
Jan 28 21:49:57 <cityLights> no I mean something like this:
Jan 28 21:50:19 <cityLights> https://lh6.googleusercontent.com/-5RVOumhneBc/VMin4fLAMhI/AAAAAAAABK8/E6eKvGZ8n_4/w346-h204/1-white.gbl.png
Jan 28 21:50:53 <cityLights> you can see the location of the ethernet port and the two connectors
Jan 28 21:51:06 <cityLights> this is as I intend to put a relay...
Jan 28 21:51:25 <cityLights> and dont wants the pins to touch the ethernet shield
Jan 28 21:52:07 <cityLights> btw, anyone knows when the offical 3.19 will be out?
Jan 28 21:52:28 <stt_michael> if you're online tomorrow .. I have an approx PCB layout you can have
Jan 28 21:52:37 <cityLights> thanks
Jan 28 21:52:41 <stt_michael> has the P8/9 headers and ethernet cutout
Jan 28 21:52:48 <cityLights> great
Jan 28 21:52:51 <stt_michael> and outline iirc
Jan 28 21:52:57 <stt_michael> will have a look
Jan 28 21:52:58 <cityLights> happy to see more ppl use geda
Jan 28 21:53:13 <cityLights> good night
Jan 28 21:53:18 <stt_michael> yeah its kinda under-used tbh .. very good base schematic/layout package
Jan 28 21:53:36 <stt_michael> aritey .. time to gtfo .. bbl on alter ego :D
Jan 28 22:04:26 <ocamlman> I am using the BB-BONE-PRU-01 which uses p9_27 -- the code TODO:\n QBBS TODO, r31, 5 does not loop infinitely as I expect, whether p9_27 is attached to 3.3v or gnd
Jan 29 00:05:05 <paul175> I am trying to build a different version of the linux kernel for the beaglebone, does anyone know what this build error means: *** No rule to make target `firmware/am335x-pm-firmware.elf', needed by `firmware/am335x-pm-firmware.elf.gen.o'.  Stop.
Jan 29 00:09:16 <veremit> you broke it (tm) .. lol .. seriously .. it needs a bit thats not been built or included somewhere
Jan 29 00:09:55 <veremit> be careful if you're cutting and pasting bits together unless you knw what you're doing :)
Jan 29 00:36:21 <ds2> jkridner: ping?
Jan 29 00:42:45 <veremit> pong lol
Jan 29 00:43:08 <ds2> veremit: you setup to troubleshoot issues on beagleboard.org ? :D
Jan 29 00:44:35 <veremit> rut roh .. :)
Jan 29 00:44:54 <veremit> I did threaten to start making notes about broken things ...
Jan 29 00:45:12 <veremit> that said .. jkr said there was an issue tracker in the site github
Jan 29 01:15:39 <ocamlman> is my GPIO issue better suited for the mailing lists?
Jan 29 01:30:41 <replaceodroid> has anyone compared odroids with beaglebone's cpu speed?
Jan 29 02:40:18 <beest> it is exactly 33.4% similar
