Dec 03 03:25:18 <qqqq> hi guys, any help available for porting --> beagleboard rev c3 ? need some clarifications =s
Dec 03 03:26:21 <vagrantc> no promises, but it's easier to clarify an asked question than an unasked one
Dec 03 03:29:20 <qqqq> its ok, just need a little guide or so =s . am tasked to do a project, and given the beagleboard rev c3 . online references of beagleboard to android is mainly the beagleboard-xm or the later versions . even with the prebuilt image i cant seem to boot up on the beagleboard . does it even support android? or the prebuilt image still need configurations?
Dec 03 03:51:38 <qqqq> hihi, any help with porting android to beagleboard ~~ omap35x
Dec 03 04:10:07 <juicyjones> I accidentally erased the emmc on my new beaglebone black, and at the same time now none of the LEDs except power show any activity at all. Do I just need to create an SD card and reflash or is something actually wrong?
Dec 03 06:15:55 <sathish> Hi,, anyone help me to start with Beaglebone black board.. how to access the gpio pins in various modes?
Dec 03 06:21:46 <Dr{Who}> sathish: did you look at the nodejs examples already?
Dec 03 06:30:24 <sathish> No.. i didn't look.. can you pls explain.. any software needed?
Dec 03 06:34:03 <Dr{Who}> when you power up your bbb. access via web page. READ READ And read some more :) play with live samples and then look at the live code.
Dec 03 06:36:57 <sathish> ok.. thank you.. Can i use this board as a microcontroller havin all perpheral devices like i2c, ethernet etc.. ?
Dec 03 06:39:42 <Dr{Who}> does anyone know if WDIOC_SETTIMEOUT with /dev/watchdog works on stock A5 firmware? I dont have a way to test right now :( but want to confirm the wd works properly.
Dec 03 06:40:23 <Dr{Who}> sathish: that is documented well in the GPIO docs. Lots and lots of pins with lots of modes.
Dec 03 06:45:09 <sathish> yes.. i saw that.. my doubt is how to access those pins for programming..
Dec 03 06:45:22 <Dr{Who}> sathish: preferred language?
Dec 03 06:47:09 <Dr{Who}> sathish: the blinking LED example is live example of GPIO control using node.js. The LED's are standard GPIO pins.
Dec 03 06:47:57 <_av500_> https://www.google.com/search?q=linux+gpio+user+space
Dec 03 06:52:42 <Dr{Who}> _av500_: I just dont grok. I think that was the first thing I did when I got mine. And I did not have to look any place but the device itself. Just all around solid stuff this BBB :)
Dec 03 06:53:39 <Dr{Who}> sathish: ya read that link :).. anyway.. anyone have any exp with watchdog on the bbb?
Dec 03 06:57:18 <sathish> yes.. if i need to use the GPIO pins as a analog inputs or for SPI or I2C, how to do that?.. how to access various modes of the gpio pins
Dec 03 06:58:05 <Dr{Who}> _av500_: any chance you could compile and test this http://embeddedfreak.wordpress.com/2010/08/23/howto-use-linux-watchdog/ and the 'interval' setting.
Dec 03 07:03:46 <sathish> is there any other links(like the last one) for any peripheral interfacing like simple microcontroller..
Dec 03 07:09:03 <_av500_> Dr{Who}: is there a dev/watchdog?
Dec 03 07:09:06 <_av500_> on BBB?
Dec 03 07:15:18 <sathish> for example i need to connect a temperature sensor on the analog input pins of the BBB connector.. how to get the analog values & process them to display as a temp?..
Dec 03 07:15:50 <beagle13> can anyone please guide me on how to connect  to your windows machine via bluetooth from beaglebone
Dec 03 07:15:52 <Dr{Who}> _av500_: should be.. hmm brb.
Dec 03 07:16:27 <Dr{Who}> _av500_: i have one on Angstrom 2012.12
Dec 03 07:19:09 <LetoThe2nd> sathish: reading analog values: http://hipstercircuits.com/reading-analog-adc-values-on-beaglebone-black/
Dec 03 07:19:11 <beagle13> sathish: one option is you can use i2c tools utility
Dec 03 07:19:22 <LetoThe2nd> sathish: (5 seconds google)
Dec 03 07:19:41 <Dr{Who}> LetoThe2nd: hay :) i was just reading that :)
Dec 03 07:19:51 <LetoThe2nd> sathish: aligning them to temperature is your own job, as its highly sensor/circuitry dependent
Dec 03 07:21:01 <sathish> I am asking the procedure to read the analog values from BBB..
Dec 03 07:21:15 <LetoThe2nd> sathish: i gave you.
Dec 03 07:26:25 <sathish> tat is setting directions know..
Dec 03 07:28:12 <sathish> there are different modes of operations of the pins from mode0 to mode7.. how to access that in windows machine..
Dec 03 07:28:23 <_av500_> windows?
Dec 03 07:28:35 <sathish> yes
Dec 03 07:28:41 <Dr{Who}> I continue to not grok :)
Dec 03 07:29:16 <Dr{Who}> I think people are confusing the BBB with a LabJack
Dec 03 07:32:00 <sathish> means?
Dec 03 08:09:17 <zer0s> lol Dr{Wh0}
Dec 03 08:10:26 <zer0s> thats a little depressing
Dec 03 08:10:57 <zer0s> but then again raspberry pi has been monopolizing any media attention
Dec 03 08:11:20 <zer0s> beagleboard was sort of a me-two project from ti
Dec 03 08:11:32 <zer0s> or at least that's how i perceived it
Dec 03 08:12:02 <rektide> n/win 109
Dec 03 08:14:26 <_av500_> zer0s: a me too started years earlier, yes
Dec 03 08:15:15 <zer0s> _av500_, whoever is first to market is first
Dec 03 08:15:31 <zer0s> doesn't matter when they start
Dec 03 08:33:44 <KotH> zer0s: well, they were on the market..uhm. 3 years earlier or so?
Dec 03 10:19:21 <Kernle> Heyho... question of the day - how do I get a serial connection to my BBB?
Dec 03 10:20:25 <KotH> to the console?
Dec 03 10:20:28 <KotH> or in general?
Dec 03 10:20:43 <Kernle> in generel. I need to find out why it won't boot
Dec 03 10:21:28 <Kernle> I tried minicom -D /dev/`dmesg | grep FTDI | grep "now attached to" | tail -n 1 | awk '{ print $NF }'` (from the rowboat wiki) but that didn't do anything.
Dec 03 10:22:32 <tbr> Kernle: do you have a connection to the UART port or only to USB?
Dec 03 10:22:54 <Kernle> only USB
Dec 03 10:23:35 <tbr> then the answer is: you don't
Dec 03 10:23:36 <KotH> get an usb2serial cable with 3.3V level
Dec 03 10:23:42 <KotH> connect it to J1
Dec 03 10:24:03 <Kernle> Nah... Well, my paper is due in 1 1/2 hours. So probably not :D
Dec 03 10:24:09 <Kernle> Thanks anyway :)
Dec 03 10:24:18 <KotH> Kernle: then send some new cell phone to .fi and good chocolate to .ch
Dec 03 10:24:41 <Kernle> KotH: ?
Dec 03 10:25:12 <KotH> Kernle: tbr collects cell phones, i collect chocolate :)
Dec 03 10:25:38 <Kernle> Ah, you sit in ch? Cool :P
Dec 03 10:26:19 <tbr> :)
Dec 03 10:26:33 <tbr> I just got a Jolla phone, I'm happy for the moment
Dec 03 10:28:20 <Kernle> KotH: Where in ch? I'm in ch for 3 months starting january ;-)
Dec 03 10:28:41 <KotH> Kernle: in the big village called zürich
Dec 03 10:29:00 <ynezz> such a boring place
Dec 03 10:29:29 <Kernle> KotH: I'll be in Luzern :D
Dec 03 10:30:55 <KotH> Kernle: why luzern?
Dec 03 10:31:02 <KotH> ynezz: why boring?
Dec 03 10:31:06 <KotH> ynezz: ever been here?
Dec 03 10:32:11 <ynezz> yep
Dec 03 10:34:24 <Kernle> KotH: Because one of my customers (I'm a freelancer web and app developer) sits there, and has offered my an internship ;-)
Dec 03 10:34:44 <Kernle> Lucky, i need a 3 month internship for my uni :)
Dec 03 10:35:45 <KotH> Kernle: dont forget your arctic class winter gear
Dec 03 10:35:52 <KotH> Kernle: .ch is a lot colder than .de
Dec 03 10:36:00 <Kernle> KotH: Yeah, I fear so :S
Dec 03 10:36:01 <KotH> Kernle: and you are in one of the colder places in .ch too
Dec 03 10:36:11 <KotH> also expect snow
Dec 03 10:36:44 <Kernle> We didn't have snow in like 5 years where I live in germany (no kidding). So I'm actually towards this :D
Dec 03 10:37:01 <KotH> where in .de?
Dec 03 10:37:54 <Kernle> Around 45min by car from cologne
Dec 03 10:38:14 <KotH> lol
Dec 03 10:38:24 <KotH> expect _REAL_WINTER_!
Dec 03 10:38:36 <Kernle> Oh boy... if you thought Android on BBB was bad... don't try ANdroid on RaPi :S
Dec 03 10:38:44 <Kernle> Will do, thanks KotH ;-)
Dec 03 10:38:54 <KotH> also expect seeing people walking around in t-shirt and shorts in deep winter... casualy
Dec 03 10:38:58 <av500> so, Android is just bad
Dec 03 10:41:06 <Kernle> av500: You don't happen to have a brother called nexsoftware in #libgdx?
Dec 03 10:45:01 <KotH> Kernle: av500 doesnt need a brother, he is the size of 3 people already
Dec 03 10:45:38 <Kernle> KotH: tbr: Any other guess why my image won't boot? I don't want to give this much tought anymore, but it somewhat bothers me.
Dec 03 10:45:43 <KotH> Kernle: http://26-26-54.hardwarebug.org/87
Dec 03 10:45:54 <KotH> Kernle: gremmlins
Dec 03 10:45:58 <Kernle> :S
Dec 03 10:46:44 <tbr> Kernle: solar flares
Dec 03 10:46:48 <Kernle> Or let me reframe that... what does the BBB want to tell me besides "you suck" when it flashes its LEDs, and then turns tehm all off?
Dec 03 10:47:51 * KotH doestn know, doesnt own a bbb
Dec 03 10:48:04 <Kernle> :(
Dec 03 10:48:07 <tbr> something went wrong before kernel boots
Dec 03 10:48:16 <tbr> ROMBL, MLO, U-Boot
Dec 03 10:48:25 <Kernle> That sucks then
Dec 03 10:49:28 <Kernle> There isn't much that could have gone wrong here :/ https://code.google.com/p/rowboat/wiki/JellybeanOnBeaglebone_WithSGX#Build_Boot_Loader_%28MLO/u-boot%29
Dec 03 10:50:05 <keesj> "I'm stil there"
Dec 03 10:50:13 <KotH> Kernle: there is a lot that can go wrong
Dec 03 10:50:34 <Kernle> :/
Dec 03 10:50:46 <KotH> like that pesky msp430 board i have on my table that refuses to talk to me over JTAG although i havent touched the whole setup in 3 months
Dec 03 10:51:06 <av500> Kernle: what does the serial log say?
Dec 03 10:52:32 <KotH> av500: he doesnt have a usb2serial cable
Dec 03 10:52:38 * Kernle slaps av500 with a serial log
Dec 03 10:52:51 <KotH> Kernle: carefull!
Dec 03 10:53:01 <KotH> Kernle: do you see that @ infront of av500?
Dec 03 10:53:18 <KotH> Kernle: it's a big sign of "do not mess with me"
Dec 03 10:53:30 <Kernle> Challenge accepted
Dec 03 10:53:31 <KotH> Kernle: or "my dady beats your dady"
Dec 03 10:53:45 <av500> no serial cable?
Dec 03 10:53:47 <av500> too bad
Dec 03 10:53:58 <av500> why is he not in the shop to buy one?
Dec 03 10:54:01 <KotH> av500: and report due in 1h
Dec 03 10:54:10 <KotH> lazy students are lazy
Dec 03 10:54:13 * vvu|Log exports some serial cable to the channel
Dec 03 11:30:06 <Vaizki_> urf
Dec 03 11:56:23 <Kernle> Duh.... the RaPi is taking its time executing the 0xbench.... GPU support wheater or not, die BBB is a lot faster even without it.
Dec 03 11:56:38 <Crofton|work> rofl
Dec 03 11:56:41 <ogra_> lol
Dec 03 11:56:48 <Crofton|work> very very true :)
Dec 03 12:03:37 <ynezz> do you play correct 0xbench.mp4 with correct license key?
Dec 03 12:09:54 <kbfirebreather> Hello everybody, I was hoping to get a little bit of input on the various beagle boards
Dec 03 12:10:14 <kbfirebreather> I'm a little confused about the capabilities on each of the variations
Dec 03 12:10:41 <kbfirebreather> particularly between the BeagleBoard and the BeagleBoard-xM
Dec 03 12:11:03 <kbfirebreather> Can you get S-Video out of the BeagleBoard?
Dec 03 12:11:06 <kbfirebreather> or NTSC
Dec 03 12:11:32 <kbfirebreather> It looks like the xM has no problem with that, but I'm not quite sure about the non xM
Dec 03 12:14:14 <KotH> Kernle: you know that your report will be very unpopular?
Dec 03 12:15:09 <kbfirebreather> Nevermind, I think I found my answer
Dec 03 12:16:13 <KotH> kbfirebreather: yes, read the documentations on each of them
Dec 03 12:16:31 <KotH> kbfirebreather: it's not easy to compare them if you've never done something like this before
Dec 03 12:16:52 <Kernle> KotH: Yep
Dec 03 12:17:36 <KotH> Kernle: use something neutral as title, or something that makes the rpi look good
Dec 03 12:21:07 <KotH> Kernle: do you have anything that the rpi is good at?
Dec 03 12:21:53 <KotH> Kernle: if you have use that... like "rpi better at getting peoples money than the bbb"
Dec 03 12:30:31 <kbfirebreather> With the beagleboard, the manual states that the RS232 Transceiver allows operation from 3 to 5.5V. Looking at the Interface Design on Page 90 of the Spec it looks like the RS232 at the connector will always be 5 Volts, but internally the BeagleBoard uses 3V signal
Dec 03 12:30:56 <kbfirebreather> Am I accurate in that statement?
Dec 03 12:31:10 <av500> internally its 1.8V
Dec 03 12:31:16 <kbfirebreather> Oh right
Dec 03 12:31:21 <av500> the beagleboard has a level shifter from 1.8 to 5V
Dec 03 12:31:24 <av500> or so
Dec 03 12:31:51 <kbfirebreather> So the 5V gets converted to 3V via the SN65C... then level shifted down to 1.8 via TXS0102 chip
Dec 03 12:31:56 <Vaizki_> hmh?
Dec 03 12:32:09 <Vaizki_> first of all it's not rs232 but ttl serial?
Dec 03 12:32:18 <kbfirebreather> ??
Dec 03 12:32:26 <Vaizki_> oh sorry no
Dec 03 12:32:27 <kbfirebreather> It's labeled as RS232
Dec 03 12:32:29 <Vaizki_> my bad
Dec 03 12:32:37 <Vaizki_> beagleboard, not beaglebone
Dec 03 12:32:58 <Vaizki_> it's 6:32am and I just woke up :D
Dec 03 12:35:05 <av500> kbfirebreather: yes
Dec 03 12:35:20 <av500> 1.8 to 3.3V then to RS232
Dec 03 12:35:59 <av500> dont know the RS232 level
Dec 03 12:36:46 <KotH> +/- some voltage
Dec 03 12:36:52 <KotH> at least 3, usually 5 at most 18
Dec 03 12:37:03 <av500> 12!
Dec 03 12:37:12 <KotH> 12 was in the 60s
Dec 03 12:37:22 <KotH> i havent seen a device that did 12v in a long time
Dec 03 12:37:27 <av500> yes, use same voltage for tube heaters :)
Dec 03 12:37:28 <KotH> most do 5V these days
Dec 03 12:37:32 <KotH> heh
Dec 03 12:37:48 <KotH> av500: did you ever have a tube version of a MAX232? ;)
Dec 03 12:38:00 <tbr> that could look funny
Dec 03 12:38:18 <av500> KotH: I should build one
Dec 03 12:39:19 <av500> well, you only need a tube opamp and drive it rail to rail
Dec 03 12:40:31 <LetoThe2nd> av500: tubie on rails?
Dec 03 12:40:38 <av500> yeah
Dec 03 12:42:01 <KotH> av500: webserver build out of tubes?
Dec 03 12:44:39 <av500> http://en.wikipedia.org/wiki/File:K2-w_Vacuum_Tube_Op-amp.jpg
Dec 03 12:45:47 <mdp> it would be a nice cape
Dec 03 12:46:09 <av500> RS232 tube cape
Dec 03 12:46:34 <ogra_> there is also a clock cape http://www.jogis-roehrenbude.de/Leserbriefe/Bruegmann-Digital-Roehren-Clock/Digital-Roehrenuhr.htm
Dec 03 12:46:36 <ogra_> :)
Dec 03 12:48:09 <KotH> av500: hmm.. only two tubes?
Dec 03 12:48:19 <KotH> av500: any circuit of it available?
Dec 03 12:48:21 <ogra_> thats enough
Dec 03 12:48:34 * ogra_ has seen pre-amps with just one tube 
Dec 03 12:48:44 <KotH> yeah, i guess it's  pentodes or something similar
Dec 03 12:49:06 <ogra_> (though the ones i know flip the phase) ...
Dec 03 12:49:24 <rob_w> omg @ogra clock
Dec 03 12:49:39 <ogra_> awesome, isnt it :)
Dec 03 12:49:46 <ogra_> fully digital ...
Dec 03 12:50:20 <av500> KotH: yes
Dec 03 12:50:49 <av500> http://www.allaboutcircuits.com/vol_3/chpt_8/14.html
Dec 03 12:51:05 <av500> one LTP and an output driver
Dec 03 12:54:52 <mdp> ogra_, get the BOM for that <30USD and CCO will produce it ;)
Dec 03 12:55:54 <av500> ogra_: kalotte oder konus?
Dec 03 12:56:12 <ogra_> hmm ?
Dec 03 12:56:34 <av500> tweeter replacement for a '72 speaker
Dec 03 12:56:44 <ogra_> kalotte
Dec 03 12:57:37 * ogra_ is Bändchen fan though ... Hannoveraner ... grown up with Quadral speakers everywhere 
Dec 03 12:58:04 <av500> cone would be more authentic
Dec 03 12:58:21 <av500> but first I need to put new caps into the xover
Dec 03 12:59:10 <Rotti> hi!
Dec 03 13:23:25 <Vaizki_> ok wtf that nixie clock :)
Dec 03 13:26:45 <Vaizki_> I wonder what the power draw of that clock is
Dec 03 13:30:23 <KotH> av500: nice, simple and straight forward
Dec 03 13:43:44 <Kernle> KotH: The paper won't be submitted to the public. And that is a good thing. The report is limited to 5 pages. And there is NO WAY to put all the knowledge I've gained working with both plattforms into 5 pages.
Dec 03 13:44:06 <Kernle> I even had to omit certain benchmark results, since I was hitten the page limit -.-
Dec 03 13:44:51 <Kernle> The most informative testcase was the Android Testcase. That worked surprisingly good on both plattforms. Altough much better on BBB - even without hardware acceleration.
Dec 03 13:47:36 <gliako> hi all
Dec 03 13:48:36 <gliako> is there anyone available to direct me with some basic instructions on how to cross compile a kernel module for beaglebone black?
Dec 03 13:51:00 <KotH> Kernle: write a 20 page paper and put it on archix
Dec 03 13:51:19 <KotH> gliako: there are dozens of tutorials online
Dec 03 13:52:24 <gliako> i know, ifound many and follow many but none of them works
Dec 03 13:52:34 <gliako> all of them are different
Dec 03 13:52:53 <KotH> they look different, but under the hood they are the same
Dec 03 13:52:57 <KotH> what's your problem
Dec 03 13:53:01 <gliako> boot from Sd or not, different kernel, different patches, different source trees
Dec 03 13:53:08 <gliako> I AM LOST
Dec 03 13:53:12 <KotH> lol
Dec 03 13:53:24 <gliako> Let me be brief and not boring
Dec 03 13:53:26 <KotH> welcome to the brave new world of embedded systems, where even the engineers who build it are lost
Dec 03 13:53:27 <Kernle> KotH: I don't know. Will do maybe. But first I have to complete another paper I'm currently working on. And that one is an important 25 page beast about shadow calculation in modern games ;-P
Dec 03 13:53:45 <KotH> gliako: for the bbb, use koesn evil non-vendor tree
Dec 03 13:53:47 <gliako> sure
Dec 03 13:53:51 <KotH> gliako: koen
Dec 03 13:53:57 <Kernle> + my bachelor thesis will base on the shadow paper I'm working on
Dec 03 13:54:03 <KotH> gliako: it's on github somehwere
Dec 03 13:54:17 <gliako> keep working an in the mean time i will typr my bullet point  questions
Dec 03 13:54:54 <KotH> gliako: for testing, boot from sd card. this makes turn around faster
Dec 03 13:55:31 <KotH> gliako: if you want background, get the "embedded linux primer"
Dec 03 13:55:51 <gliako> In order to compile a kernel module (simple Hello routine) i have to download on my host machine a kernel source code in order to build it right?
Dec 03 13:56:01 <KotH> gliako: if you need even more background "the design of the unix operating system" by bach ;)
Dec 03 13:56:16 <KotH> gliako: you should _not_ compile modules seperately
Dec 03 13:56:32 <KotH> gliako: modules depend on having the same configuration as the kernel they are supposed to used with
Dec 03 13:56:39 <gliako> ok
Dec 03 13:56:51 <KotH> gliako: part of the modules also depend on having the same gcc version
Dec 03 13:57:34 <gliako> beaglebone black shows 3.8.13 kernel but i cannot find it and download it on my host machine
Dec 03 14:01:42 <Kernle> KotH: I'm driving to my local electric store. What should I get again? serial2USB?
Dec 03 14:07:28 <gliako> people
Dec 03 14:07:34 <gliako> i need your help
Dec 03 14:08:33 <gliako> can someone direct me to a tutorial or paper where i can achive from scratch (Linux host machine and beaglebone black) to build a simple "hello" kernel module?
Dec 03 14:08:57 <_Rotti> do you need cross compiling?
Dec 03 14:09:11 <gliako> i need steps/requirements for host and beaglebone black
Dec 03 14:09:19 <gliako> please guys!!!
Dec 03 14:09:34 <_Rotti> first start with compiling a simple module for your host
Dec 03 14:09:39 <gliako> google is CHAOS!
Dec 03 14:09:52 <_Rotti> when done, you need to build a kernel for your BB on the host
Dec 03 14:10:20 <_Rotti> then, just set KDIR (?) and CROSS_COMPILE to the BB sources
Dec 03 14:10:27 <_Rotti> this should be it
Dec 03 14:10:30 <gliako> I have done that!
Dec 03 14:10:37 <gliako> and it works!
Dec 03 14:10:50 <gliako> but then i need to match the kernel of my BBB
Dec 03 14:10:56 <gliako> and build it
Dec 03 14:11:04 <gliako> and here is where i am lost
Dec 03 14:11:28 <gliako> host kernel is 3.8.0.33 and BBB 3.8.13
Dec 03 14:12:07 <gliako> how do i find 3.8.13, download it on my host and cross compile my module for BBB on host???
Dec 03 14:13:08 <_Rotti> github.com/beaglebone or similar
Dec 03 14:13:21 <gliako> should i build a new kernel for BBB?
Dec 03 14:13:31 <_Rotti> yepp
Dec 03 14:13:40 <_Rotti> guess so, at least
Dec 03 14:14:04 <_Rotti> had problems when the module and the kernel were built on different machines with different versions of gcc
Dec 03 14:14:34 <gliako> this is what i have seen
Dec 03 14:15:02 <gliako> so your suggestion is to get sources for latest stable BBB kernel (ideally Angstrom)
Dec 03 14:15:21 <_Rotti> probably....
Dec 03 14:15:39 <gliako> build it
Dec 03 14:15:46 <gliako> then creat image and boot it from sd
Dec 03 14:16:00 <gliako> and then build kernel on host with same sources
Dec 03 14:16:12 <_Rotti> ...and same compiler, of course
Dec 03 14:16:15 <gliako> and finally import .ko file on BBB
Dec 03 14:16:29 <_Rotti> yes, this should be it
Dec 03 14:16:51 <gliako> hmmm, i will do it again
Dec 03 14:17:06 <gliako> i am sure this is what i have done before
Dec 03 14:17:11 <gliako> maybe i took bad sources
Dec 03 14:17:40 <_Rotti> did you set the board, CROSS_COMPILE=..., ARCH=arm, ...?
Dec 03 14:17:47 <gliako> do you have in mind a good link or paper which outlines these steps with working results?
Dec 03 14:17:55 <_Rotti> does the board boot the correct kernel?
Dec 03 14:18:00 <gliako> to be honest i dont remember
Dec 03 14:18:04 <gliako> maybe not
Dec 03 14:18:11 <_Rotti> sorry, no
Dec 03 14:19:02 <gliako> CROSS_COMPILE=..., ARCH=arm, ... must have the path of the downloaded sources and compiler
Dec 03 14:19:05 <gliako> right?
Dec 03 14:19:33 <_Rotti> CROSS_COMPILE=arm-linux-gnueabihf- (for my system)
Dec 03 14:19:49 <gliako> yeap
Dec 03 14:20:03 <gliako> Thanks for your time _Rotti
Dec 03 14:20:10 <gliako> much appreciated!
Dec 03 14:20:15 <gliako> Honestly!
Dec 03 14:20:24 <_Rotti> hope it helps ;)
Dec 03 14:20:25 <honestly> ok gliako
Dec 03 14:20:36 <gliako> haha
Dec 03 14:21:24 <KotH> gliako: if you want to write your own kernel module, get the ldd3
Dec 03 14:22:31 <gliako> what is this?
Dec 03 14:22:51 <_Rotti> http://lwn.net/Kernel/LDD3/ <- this one, koth? i'm still looking for a good book on development for modules
Dec 03 14:23:28 <KotH> _Rotti: yes, that one
Dec 03 14:23:48 <KotH> _Rotti: huh? ldd3 is _the_one_book_to_rule_all_modules_
Dec 03 14:23:56 <KotH> _Rotti: everyone should point you at it
Dec 03 14:25:21 <_Rotti> KotH: just asked co workers for now... they had more stuff regarding the network stack
Dec 03 14:26:31 <gliako> i have bought it 2 weeks now and still waiting on delivery
Dec 03 14:26:31 <gliako> GGGGRRRRRR
Dec 03 14:49:18 <KotH> _Rotti: there is specialized docu for certain subsys
Dec 03 14:49:42 <KotH> _Rotti: iirc mel gorman wrote a 200+ pages "paper" on how the memory managment works
Dec 03 15:00:42 <Kernle> Okay... so a serial2usb costs 20€ at our local electric store. Screw that, I will ask my professor in uni tomorrow. Plus I will look good for working on thr project even thoguh the project is over.
Dec 03 15:03:10 <av500> you need USB2ttl
Dec 03 15:03:14 <av500> not RS232
Dec 03 15:04:26 <av500> http://www.watterott.com/de/TTL-232R-USB-Serial-Converter-33V
Dec 03 15:04:58 <Kernle> Whats the difference av500?
Dec 03 15:05:06 <Vaizki_> voltage levels
Dec 03 15:05:08 <av500> one is TTL, the other is RS232
Dec 03 15:05:42 <Kernle> Well, google came up with this, so.... http://dave.cheney.net/2013/09/22/two-point-five-ways-to-access-the-serial-console-on-your-beaglebone-black
Dec 03 15:05:44 <carpman> if you try to connect RS232 voltages to the console on the BBB, you will burn out the console port. You need TTL voltage levels
Dec 03 15:05:50 <Vaizki_> if you have other dev boards etc, maybe you already have a usable ttl serial port on something
Dec 03 15:06:52 <Kernle> Well, the tutorial states that the voltage pin on the BBB isn't connected. Can someone confirm this?
Dec 03 15:06:59 <av500> true
Dec 03 15:07:03 <av500> so?
Dec 03 15:07:04 <Vaizki_> confirmed
Dec 03 15:07:15 <av500> its not about the voltage pin
Dec 03 15:07:28 <joom> Has anyone used PWM in u-boot?
Dec 03 15:07:36 <av500> you could do something wild and google "RS232" and then google "TTL"
Dec 03 15:10:42 <Kernle> TTL just comes up the transistor-transistor-logic ._.
Dec 03 15:11:06 <carpman> Kernle: you need a serial adapter that does 3.3 volt signaling on one side and USB on the other.
Dec 03 15:11:54 <KotH> Kernle: get "tietze&schenk"
Dec 03 15:12:05 <KotH> Kernle: that's step #2 in learning electronics
Dec 03 15:12:45 <Vaizki_> BBB also works with 5V ttl on the debug serial
Dec 03 15:12:48 <Kernle> I don't want to learn electronics :S I had that stuff 3 years in school._.
Dec 03 15:12:57 <Vaizki_> I know it's not official or recommended but it does ;)
Dec 03 15:13:02 <das> KotH: I take it step 1 is put the fingers in the electrical outlet to learn to never do that again ?
Dec 03 15:13:36 <Kernle> KotH: You learn to respect electronics, after one of your idiot classmates blows up a capacitor
Dec 03 15:14:03 <Kernle> Might this work then? http://www.amazon.de/USB-TTL-Konverter-Modul-mit-eingebautem-CP2102/dp/B008RF73CS
Dec 03 15:14:14 <KotH> das: no, step #1 is to learn german ;)
Dec 03 15:14:43 <Vaizki_> Kernle: yes, I have similar ones.
Dec 03 15:14:48 <Vaizki_> they are not as good as FTDI ones
Dec 03 15:14:53 <KotH> Kernle: oh.. we soldered capacitors into the power socked at our highschool. it was fun watching the teacher jump when he plugged something in :)
Dec 03 15:15:03 <KotH> sockets*
Dec 03 15:15:08 <Kernle> KotH: We should have done that :D
Dec 03 15:15:20 <Vaizki_> but for just debug serial access the cp2102 stuff is ok
Dec 03 15:15:33 <Vaizki_> you need to find the right drivers though
Dec 03 15:15:38 <Kernle> :S duh...
Dec 03 15:16:01 <Kernle> I guess I will do some further test before I get this crap.
Dec 03 15:16:08 <av500> das: www.jeanpierrepoulin.com/PDF/transistor.pdf‎
Dec 03 15:16:21 <av500> its about guitar amps, but the principles are the same
Dec 03 15:16:26 <av500> for you hifi project
Dec 03 15:16:40 <Vaizki_> you don't have anything like arduino or msp430 boards to use as usb-to-ttl converters?
Dec 03 15:17:10 <Kernle> Vaizki_: Nope, why would I. Never did anything productive with modern boards. The stuff I have is lend from university.
Dec 03 15:17:26 <Kernle> So, they should have this usb-ttl thingy laying around somewhere.
Dec 03 15:17:38 <Kernle> Maybe I'll find the cause for the BBB not booting without it though...
Dec 03 15:17:44 <Vaizki_> not even a raspberry pi?! :D
Dec 03 15:17:59 <Kernle> The RaPi is lend, too :D
Dec 03 15:19:02 <Vaizki_> well you can use it as a ttl serial server
Dec 03 15:19:18 <Vaizki_> it has a ttl serial port on the expansion connector
Dec 03 15:19:43 <bradfa> is it 12 or 21?
Dec 03 15:19:55 <av500> 54!
Dec 03 15:19:59 <Vaizki_> 42
Dec 03 15:20:23 <av500> no trolling
Dec 03 15:21:27 <KotH> lol
Dec 03 15:21:44 <KotH> p00r bradfa, he only tried to help!
Dec 03 15:22:44 <Vaizki_> http://www.ebay.com/itm/FT232RL-Serial-adapter-Module-USB-TTL-3-3V-5V-Mini-USB-TTL-Arduino-/300987591306?pt=LH_DefaultDomain_0&hash=item4614422a8a
Dec 03 15:22:51 <Vaizki_> I ordered a couple of those
Dec 03 15:22:53 <Kernle> Lol.... "for Raspberry Pi" - first image is a BBB :D http://www.adafruit.com/products/954
Dec 03 15:22:58 <Vaizki_> haven't gotten them yet
Dec 03 15:25:01 <Kernle> Anyhow, back to my board problem. If it doesn't boot, aka just flashes its LEDs and then goes black, its either MLO or u-boot, right
Dec 03 15:26:21 <carpman> Kernle: it could be a kernel problem. There is no way to tell without the output of the console.
Dec 03 15:26:25 <Vaizki_> well MLO is uboot "mini"
Dec 03 15:26:26 <mdp> av500, can we at least use foul language here?
Dec 03 15:26:52 <Kernle> okay carpman :( I will recompile my stuff then, and see if there are any errors
Dec 03 15:27:05 <Vaizki_> what flashes the leds in boot before the kernel is up?
Dec 03 15:27:14 <Vaizki_> I've never thought about it
Dec 03 15:27:15 <carpman> uboot
Dec 03 15:27:32 <Vaizki_> they put in special support for it?
Dec 03 15:28:36 <av500> superduper led driver
Dec 03 15:29:00 <Vaizki_> so at least he has MLO and uboot loaded
Dec 03 15:29:11 <Vaizki_> if the leds flash
Dec 03 15:29:31 <carpman> Vaizki_: most probably the kernel is panicking somewhere in the boot process. That somewhere is critical to fixing the problem, though.
Dec 03 15:29:56 <Vaizki_> yea, I've had my share of boot debugging...
Dec 03 15:30:06 <mdp> do you have jtag?
Dec 03 15:30:14 <Vaizki_> although I must admit I don't find the default BBB uboot very helpful in its boot messages either :)
Dec 03 15:30:22 <mdp> or perhaps you could enable earlyprintk?
Dec 03 15:30:51 <mdp> Vaizki_, you can enable debug in u-boot
Dec 03 15:31:58 <Vaizki_> yea I can. but look at all the people who come on this channel...
Dec 03 15:34:18 <Vaizki_> it would be nice if uboot at least printed out some basic stuff ... like when it loads a device tree, kernel etc.. just print out what device, what path, loaded into which address, what size :)
Dec 03 15:34:36 <Vaizki_> we would have so much more useful pastebins from the people coming and asking about boot
Dec 03 15:34:48 <carpman> and boot would take 3 times as long
Dec 03 15:35:03 <Vaizki_> why?
Dec 03 15:35:15 <Vaizki_> to print 5-10 lines more at boot?
Dec 03 15:36:33 <carpman> oh, just the devices. I guess that wouldn't be that much. Or they could google how to turn uboot debugging on and learn an important life lesson on how to search for things.
Dec 03 15:36:46 <mdp> Vaizki_, but it's a production build..it's abnormal to turn on debug for a production u-boot or kernel build. does that make sense?
Dec 03 15:37:16 <mdp> Vaizki_, BBB has a turnkey s/w load that's known to work so debug enabled by default is not needed
Dec 03 15:37:23 <av500> I wish BBB had usb serial
Dec 03 15:37:30 <Vaizki_> av500: yea me too :)
Dec 03 15:37:34 <Kernle> Well, I looked again at the boot. It just turns on the first two leds, and then shuts down. I made a short video: https://www.dropbox.com/s/4xyjz8684szlm9y/2013-12-03%2016.31.15.mp4
Dec 03 15:37:39 <mdp> av500, I wish BBB had miniPCIe
Dec 03 15:37:41 <av500> get
Dec 03 15:37:43 <av500> a
Dec 03 15:37:44 <av500> serial
Dec 03 15:37:52 <Vaizki_> mdp: look at all the people coming on to the channel asking about boot debugging
Dec 03 15:38:04 <av500> mdp: I wish it had ACPI
Dec 03 15:38:07 <carpman> Vaizki_: https://www.tindie.com/products/makertronic/beagle-bone-black-usb-console/, also the new RS232 cape will have access to the console.
Dec 03 15:38:11 <av500> then jonmasters would help debug it
Dec 03 15:38:15 <carpman> av500: no trolling
Dec 03 15:38:16 <mdp> av500, we can get that
Dec 03 15:38:37 <av500> carpman: clever play to sell more capes
Dec 03 15:38:41 <Vaizki_> I don't want a RS232 cape...
Dec 03 15:38:53 <mdp> Vaizki_, then you would have people coming asking to debug there USB HCI driver on their host
Dec 03 15:38:59 <mdp> s/there/their/
Dec 03 15:39:27 <mdp> Vaizki_, they very clearly offer places to get the usb->serial cable for BBB, you should get one
Dec 03 15:39:45 <mdp> Vaizki_, it's an essential tool for somebody not just hooking up to an HDMI display
Dec 03 15:39:54 <Vaizki_> hey I don't disagree. but they still come on here and bug the hell out of us :D
Dec 03 15:40:04 <mdp> past the link
Dec 03 15:40:07 <mdp> done
Dec 03 15:40:19 <Vaizki_> I have never hooked up a HDMI display to my BBB
Dec 03 15:40:32 <mdp> maybe I need to come out of retirement
Dec 03 15:40:51 <Vaizki_> that said, I did install arch linux on it without having a usb2ttl serial handy...
Dec 03 15:40:59 <mdp> that's nice
Dec 03 15:41:19 <Vaizki_> I did need a usb usd card reader though
Dec 03 15:41:24 <Kernle> Is there an overview what different led reactions at boot mean? Like, it turns on the first two, now what?
Dec 03 15:41:35 <av500> no
Dec 03 15:41:36 <av500> get
Dec 03 15:41:38 <av500> a
Dec 03 15:41:40 <Vaizki_> :D
Dec 03 15:41:41 <av500>  serial
Dec 03 15:41:42 <Vaizki_> SERIAL
Dec 03 15:41:56 <carpman> av500: lol

Dec 03 15:42:19 * Kernle puts av500 in place for a serial cable
Dec 03 15:42:25 <Kernle> Now talk serial thingy!
Dec 03 15:43:35 <carpman> oh wait, I just looked at the source. First 2 LEDs indicate "GET A SERIAL CABLE TO DEBUG FURTHER"
Dec 03 15:43:54 <Vaizki_> there should be an arduino cape with 328p and a usb-serial with jumpers to select whether it connects to arduino or BBB debug serial :)
Dec 03 15:43:59 <Vaizki_> that would sell to the newbies
Dec 03 15:44:11 * Kernle puts carpman into his fridge

Dec 03 15:45:58 <Kernle> Well yeah mdp. That tells me what the leds indicate. But this not answer my question.
Dec 03 15:46:13 <mdp> <Kernle> Is there an overview what different led reactions at boot mean? Like, it turns on the first two, now what?
Dec 03 15:46:17 <mdp> your question is poorly worded and vague. try again
Dec 03 15:46:24 <mdp> but first, GET A SERIAL
Dec 03 15:46:26 <Kernle> :(
Dec 03 15:46:34 <Kernle> *sad puppy face*
Dec 03 15:46:34 <Vaizki_> I guess those led descriptions only apply to when the kernel is up
Dec 03 15:46:43 <mdp> of course
Dec 03 15:46:56 <mdp> they are driven by the triggers framework in the kernel
Dec 03 15:47:13 <Vaizki_> he wants to know what they mean when uboot is running the show
Dec 03 15:47:31 <mdp> if he has no SERIAL, how does he know what is running?
Dec 03 15:48:02 <av500> female intuition
Dec 03 15:48:06 <Vaizki_> from the leds! .. just kidding ;)
Dec 03 15:48:26 <av500> as fefe would say: zeitbinder
Dec 03 15:50:42 <Kernle> c kernel
Dec 03 15:50:46 <Kernle> duh... wrong windows
Dec 03 15:51:30 <av500> java kernel
Dec 03 15:51:40 <Kernle> Java is awesome \o/
Dec 03 15:51:57 <KotH> people have been banned for less
Dec 03 15:52:04 <Kernle> o_o

Dec 03 15:52:41 <KotH> av500: could you please ban mdp?
Dec 03 15:52:48 <KotH> av500: he promotes the use of java
Dec 03 15:52:57 <Kernle> I develop games in java oô
Dec 03 15:53:07 <carpman> really...
Dec 03 15:53:11 <Kernle> Android...
Dec 03 15:53:22 <av500> KotH: java is grear
Dec 03 15:53:24 <av500> great
Dec 03 15:53:40 <carpman> all is explained
Dec 03 15:54:17 <Vaizki_> now get a serial
Dec 03 15:54:22 <Vaizki_> neeeext!
Dec 03 15:54:34 <mdp> I prefer Torvald's Java to Google's Java
Dec 03 15:56:42 * Kernle connects Vaizki_ and av500 with a serial cable
Dec 03 15:56:44 <Kernle> Now what?
Dec 03 15:57:24 <carpman> you stop using /me and get the hardware that multiple different people have insisted you need to diagnose the problem
Dec 03 15:58:01 <Kernle> Well, i send the mail to my prof, so I hope I got my stuff tomorrow.
Dec 03 15:59:30 <mdp> we'll note in the ticket that the user is acquiring a SERIAL and will report back tomorrow. will keep the ticket open

Dec 03 16:36:51 <__Rotti> Guest53406: does the sd card work in another device (cell phone, camera, ...)?
Dec 03 16:37:27 <Guest53406> ls: cannot access /dev/sda*: No such file or directory
Dec 03 16:38:16 <__Rotti> then the card seems to be broken
Dec 03 16:39:46 <av500> try:
Dec 03 16:39:49 <av500> 1) different card
Dec 03 16:39:53 <av500> 2) differen card reader
Dec 03 16:40:06 <Splat725> Hello all.
Dec 03 16:40:51 <Splat725> I am just wondering, Can the BBB play full 1080P video?
Dec 03 16:41:05 <av500> no
Dec 03 16:41:07 <av500> and no
Dec 03 16:41:34 <av500> at least not at fps rates that you would find agreeable
Dec 03 16:42:02 <Splat725> What about 720P?
Dec 03 16:43:06 <av500> no
Dec 03 16:43:15 <av500> also, 16bit output only
Dec 03 16:43:27 <av500> so even if it could decode and resize, it would still look like crap
Dec 03 16:43:44 <Splat725> Figured as much, just thought I would confirm with people who knew definitely
Dec 03 16:59:17 <Guest53406> It is puzzling, the problem with sd card. It should be working, when I successfully used it to update BBB. I am now trying the sdcard formatting utility and complete rewrite.
Dec 03 17:01:15 <av500> to update the BBB, the card was in the sdcard slot, no?
Dec 03 17:01:26 <Guest53406> yes
Dec 03 17:01:29 <av500> now its in an sdcard reader, no?
Dec 03 17:01:36 <Guest53406> yes
Dec 03 17:01:43 <Guest53406> can it mean problem with the reader_
Dec 03 17:01:45 <Guest53406> ?
Dec 03 17:01:54 <av500> [17:39] <av500> 1) different card
Dec 03 17:01:55 <av500> [17:39] <av500> 2) differen card reader
Dec 03 17:03:19 <Guest53406> Is there any ideal capacity for sd card? I can buy tomorrow, perhaps 4GB rather?
Dec 03 17:03:36 <av500> no
Dec 03 17:03:44 <av500> buy a card that says "sandisk" on it
Dec 03 17:03:50 <av500> and not from a street vendor
Dec 03 17:04:52 <Guest53406> What about usb reader vendor or successfully tested product?
Dec 03 17:05:15 <av500> there isa million different usb readers
Dec 03 17:05:37 <av500> under a trillion  different brands
Dec 03 17:05:44 <av500> all from the same factory in China
Dec 03 17:05:50 <Guest53406> ROFL
Dec 03 17:05:54 <av500>  successfully tested means nothing
Dec 03 17:06:09 <av500> luckily, they are cheap
Dec 03 17:07:20 <Guest53406> Thanks for info, I will try to be persistent and get it working:).
Dec 03 17:09:54 <juicyjones> Guest53406 a new reader will probably fix that right up
Dec 03 17:10:39 <juicyjones> Guest53406 were you ever able to format and flash your sdcard before, or has it failed every time you've tried?
Dec 03 17:11:58 <Dr{Who}> wow.. adafruit had 40 last night I got one but now they have none.. Glad I decided to get one.
Dec 03 17:12:16 <Guest53406> Never from beagle, I was always capable to acces the sd card from PC and format it there.
Dec 03 17:17:17 <Kernle> Hmm... I just checked. The TI Android Testbuild doesn't work with the same problem like my own Android build :S
Dec 03 17:18:22 <av500> compare the logs :)
Dec 03 17:18:56 <Kernle> av500: .... serial? ;-)
Dec 03 17:19:26 <av500> or parallel
Dec 03 17:20:17 <Kernle> Well... it does bother me that even the testbuild doesn't work :S Will try a different distro.
Dec 03 17:24:14 <Guest53406> It WORKS!  It was really transcend usb reader,who caused the problem. I found luckily old usb mmc/sd card reader and it mounted :).
Dec 03 17:24:23 <Guest53406> Thanks for help:)
Dec 03 17:28:23 <Dr{Who}> Q. I cant find a good page that confirms this. And I have not plugged mine BBB into a host ever. I presume the host can access the emmc and sd card via usb only because the running kernel has the host driver. Ie no kernel running no access to the bbb storage.
Dec 03 17:28:48 <av500> right
Dec 03 17:28:53 <av500> the kernel has a usb device driver
Dec 03 17:29:00 <av500> so it appears as a device to the PC host
Dec 03 17:29:23 <av500> in Linux lingo that is called a "gadget" driver
Dec 03 17:29:49 <Dr{Who}> yep. cool. just wanted to make sure no hardware magic existed.
Dec 03 17:30:12 <av500> it would be ROM code magic, but no
Dec 03 17:37:45 <Dr{Who}> wow 176k of rom space. Thats over 2 * of the size of the Pic chip on my own embeded boards. Thats lots of room. Wonder how much uboot stage 1 takes up.
Dec 03 17:38:17 <av500> what for?
Dec 03 17:39:28 <Dr{Who}> anyone know how much of the onboard rom on the AM335x is used on the BBB?
Dec 03 17:41:36 <Travis7s> Does anyone know if there is a distributor that actually has beaglebone blacks?
Dec 03 17:41:41 <av500> Dr{Who}: ?
Dec 03 17:41:48 <av500> the onboard ROM is fixed for amm AM335x
Dec 03 17:41:55 <av500> for all*
Dec 03 17:41:58 <Dr{Who}> yes I know.
Dec 03 17:42:02 <Dr{Who}> its "ROM"
Dec 03 17:42:13 <ogra_> Dr{Who}, enough to load the first stage bootloader ...
Dec 03 17:42:17 <Dr{Who}> but how much of the 180K was used
Dec 03 17:43:52 <Quinto> hi all..i have create a .service for to start my app at boot: http://pastebin.com/sqcvg4wV but at start i have this error ttyUSB0 dont exist... if i do systemctl stop myservice and systemctl start myservice it work correctly.. Someone can help me?
Dec 03 17:47:07 <av500> pastebin app.sh
Dec 03 17:47:44 <juicyjones> Travis7s Amazon just delivered one to me yesterday
Dec 03 17:49:01 <kartikeya> hiii
Dec 03 17:49:06 <kartikeya> i need help
Dec 03 17:49:11 <kartikeya> any1?
Dec 03 17:49:49 <kartikeya> >>>>>>>>>
Dec 03 17:49:55 <av500> <<<<<<<<
Dec 03 17:49:56 <Quinto> av500: http://pastebin.com/uFgBX4nZ
Dec 03 17:50:00 <juicyjones> no need to announce kartikeya just ask your question or not
Dec 03 17:50:31 <av500> Quinto: and what prints this error ttyUSB0 ?
Dec 03 17:50:44 <Quinto> av500: ttyUSB0 dont exist
Dec 03 17:51:00 <Quinto> i think that i must insert After=getty@ttyUSB0.service
Dec 03 17:51:05 <Quinto> and Required=ttyUSB0
Dec 03 17:51:08 <Quinto> i think...
Dec 03 17:51:21 <av500> what SW needs tty usb?
Dec 03 17:51:21 <Quinto> getty-serial@ttyUSB0.service
Dec 03 17:51:35 <Quinto> prova_qt_BBB
Dec 03 17:51:41 <Quinto> service run app.sh
Dec 03 17:51:41 <Vaizki_> if you think so, why not try it?
Dec 03 17:51:54 <Quinto> app.sh run prova_qt_BBB -qws
Dec 03 17:52:02 <Quinto> now i cant try it
Dec 03 17:52:18 <kartikeya> i just bought a new beagle bone black and i cannot find it in my computer
Dec 03 17:52:25 <av500> if you app needs ttyUSB, why run a getty on it?
Dec 03 17:52:31 <kartikeya> i installed the drivers...i m on win8
Dec 03 17:52:40 <av500> how is it connected?
Dec 03 17:52:45 <kartikeya> usb
Dec 03 17:52:53 <kartikeya> and DC power
Dec 03 17:53:01 <kartikeya> usb to mini usb port
Dec 03 17:53:09 <av500> and windows shows the usb device?
Dec 03 17:53:16 <kartikeya> nope
Dec 03 17:53:18 <kartikeya> nothing
Dec 03 17:53:25 <kartikeya> thats what concerns me
Dec 03 17:53:39 <Vaizki_> does the bbb boot? leds flashing?
Dec 03 17:53:44 <kartikeya> yes
Dec 03 17:53:49 <kartikeya> i see 3 led light
Dec 03 17:53:56 <kartikeya> however the 4th one wont start
Dec 03 17:54:16 <kartikeya> i have inserted the micro sd
Dec 03 17:54:22 <Quinto> av500: my app need ttyUSB0 for read and write
Dec 03 17:54:34 <Vaizki_> don't insert a uSD unless you want to boot from it
Dec 03 17:54:35 <kartikeya> by writting with win32disk soft
Dec 03 17:54:47 <Quinto> but my service when start at boot dont work and if i do systemctl status applicazione.service
Dec 03 17:54:55 <kartikeya> and NOOBS OS
Dec 03 17:54:57 <Quinto> i view error ttyUSB0 dont exist
Dec 03 17:55:15 <juicyjones> kartikeya first, unplug everything including your SD card, then plug just the BBB into your computer via usb
Dec 03 17:55:25 <kartikeya> okay
Dec 03 17:55:25 <Quinto> if i do systemctl stop applicazione and ssystemctl tart applicazione it work correctly
Dec 03 17:55:30 <kartikeya> let me do that...
Dec 03 17:55:31 <av500> Quinto: again, what has this got to do with a getty on ttyusb?
Dec 03 17:55:39 <juicyjones> isn't noobs OS for the rpi?
Dec 03 17:55:48 <av500> Quinto: I guess systemd runs your unit before USB is there
Dec 03 17:55:55 <Quinto> i think it enable ttyUSB0 before my app
Dec 03 17:56:02 <av500> you need to make it wait for USB devices
Dec 03 17:56:05 <kartikeya> done
Dec 03 17:56:07 <Vaizki_> yes NOOBS is for RPi, not BBB
Dec 03 17:56:16 <kartikeya> okay
Dec 03 17:56:19 <av500> wtf is noobs?
Dec 03 17:56:23 <kartikeya> didnt knew that
Dec 03 17:56:25 <av500> other than what comes to my mind
Dec 03 17:56:25 <juicyjones> a distro for rpi
Dec 03 17:56:27 <Quinto> no USB devices is already connected to USB port
Dec 03 17:56:34 <Quinto> at boot
Dec 03 17:56:36 <av500> sure
Dec 03 17:56:45 <av500> that does not mean the kernel has enumerated them
Dec 03 17:56:51 <kartikeya> nothing is shown in my computer
Dec 03 17:56:55 <kartikeya> stillll
Dec 03 17:56:59 <Quinto> so how i can resolve?
Dec 03 17:57:07 <av500> [18:55] <av500> you need to make it wait for USB devices
Dec 03 17:57:11 <juicyjones> kartikeya what is happening on the BBB?
Dec 03 17:57:13 <Quinto> and how?
Dec 03 17:57:27 <av500> by taking my words and reformulating them into a question for google
Dec 03 17:57:33 <av500> no?
Dec 03 17:57:36 <kartikeya> just one blue light is active
Dec 03 17:57:53 <kartikeya> the one near power source of DC
Dec 03 17:58:01 <Vaizki_> blinking?
Dec 03 17:58:06 <kartikeya> nope
Dec 03 17:58:14 <juicyjones> kartikeya did you try to flash the eemc already?
Dec 03 17:58:25 <kartikeya> how do i do that?
Dec 03 17:58:34 <juicyjones> kartikeya I'll take that as a no
Dec 03 17:58:55 <juicyjones> have you done anything at all besides plug in cables kartikeya?
Dec 03 17:58:58 <kartikeya> i have tried many things
Dec 03 17:59:03 <kartikeya> yes
Dec 03 17:59:05 <kartikeya>  i have
Dec 03 17:59:43 <kartikeya> i tried holding the boot button...that is what i believe for about 30 seconds with micro sd inserted
Dec 03 18:00:07 <kartikeya> the boot button should be the button along the big usb port
Dec 03 18:01:11 <kartikeya> help!!!
Dec 03 18:01:24 <juicyjones> I'm new to this, but all I know is that the first thing I did was accidentally erase the eemc and my sdcard. That caused a crash course in how to flash the BBB and my sdcards
Dec 03 18:01:58 <juicyjones> read up on flashing the OS to your SD card kartikeya, you have to pick something besides NOOBS
Dec 03 18:02:29 <kartikeya> so i was working correctly i take it
Dec 03 18:02:47 <kartikeya> that is the correct way to flash
Dec 03 18:03:01 <kartikeya> is there a xbmc os for beagle bone
Dec 03 18:03:10 <Vaizki_> no
Dec 03 18:03:20 <Vaizki_> beagle bone is not a good xbmc platform
Dec 03 18:03:50 <ogra_> s/a good//
Dec 03 18:04:00 <Vaizki_> there's about zero (0) reasons to run XBMC on BBB
Dec 03 18:04:09 <Dr{Who}> Vaizki_: just to confirm on that. It is on Ti's plate to add some acceleration drivers and that would be a different story?
Dec 03 18:04:24 <Vaizki_> not really
Dec 03 18:04:28 <ogra_> Dr{Who}, there is no hardware for video decoding ...
Dec 03 18:04:29 <Dr{Who}> othern than the lack of 1080p
Dec 03 18:04:34 <ogra_> no driver will help
Dec 03 18:04:38 <Dr{Who}> k. thanks.
Dec 03 18:04:45 <Vaizki_> and it's only 16bit color out
Dec 03 18:04:58 <ogra_> it does GLES but no video decoding with the HW it has
Dec 03 18:05:09 <Dr{Who}> I had read someplace about Ti needing to provide some data to get some acceleration I thought it was video.
Dec 03 18:05:38 <kartikeya> okay
Dec 03 18:05:47 <kartikeya> that was just for information
Dec 03 18:06:00 <kartikeya> so can you please help me to detect my bbb on my computer
Dec 03 18:06:07 <kartikeya> nothing seems to work
Dec 03 18:06:22 <Vaizki_> you are not accepting help
Dec 03 18:06:43 <Dr{Who}> kartikeya: if the BBB is not booting your USB host access is also down. You will need to read up on flashing and running from the uSD
Dec 03 18:07:03 <kartikeya> okay
Dec 03 18:07:16 <kartikeya> please provide me a good distro link for bbb
Dec 03 18:07:41 <Vaizki_> can I do your homework also?
Dec 03 18:07:51 <Dr{Who}> kartikeya: everyone will have diff opinion on that. I suggest putting back to stock angstrom at first.
Dec 03 18:08:22 <Ferris> µ
Dec 03 18:08:52 <juicyjones> IIRC once TI releases the DRM pieces the drivers can commence and they'll be fine.
Dec 03 18:09:13 <juicyjones> kartikeya you have to at least go to the homepage and read about what to do first. come on.
Dec 03 18:09:44 <kartikeya> Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.08.21.img.xz
Dec 03 18:09:48 <kartikeya> i have read people
Dec 03 18:09:51 <kartikeya> its not like that
Dec 03 18:10:03 <kartikeya> i just got confused with rpi and beagle bone black
Dec 03 18:10:07 <Vaizki_> even if you got video decoded on the BBB, you'd still be stuck with 16bit color and 720p if you want sound
Dec 03 18:10:11 <kartikeya> it seems i places the wrong order
Dec 03 18:10:11 <Vaizki_> just not worth it
Dec 03 18:10:40 <juicyjones> Vaizki_ until drivers are written
Dec 03 18:10:42 <Dr{Who}> av500: Finished reading on the rom boot code. So its private code and cant be factory loaded. Got it. I figured it was a flash once or something. Wonder if the ROM code passed the Auto industry and mill tests. They are giving out any details on it afaik.
Dec 03 18:10:47 <kartikeya> i guess i will just make a firewall out of iut
Dec 03 18:10:49 <juicyjones> kartikeya http://beagleboard.org/Getting%20Started
Dec 03 18:10:49 <Vaizki_> juicyjones: no, until forever
Dec 03 18:11:11 <juicyjones> kartikeya at the bottom of that page it has a whole section about distros that people are working on
Dec 03 18:11:18 <Vaizki_> the pixel clock and bus width on the board limit you
Dec 03 18:16:11 <Vaizki_> but I see they added 1080p @ 24fps .. which is nice. but it's always going to be RGB565
Dec 03 18:17:59 <Vaizki_> going to 24bit color would have wiped out 8 pins from the expansion headers
Dec 03 18:18:08 <Vaizki_> 8 more that is
Dec 03 18:18:53 <juicyjones> that should more than satisfy all but the XBMC'ers Vaizki_
Dec 03 18:19:07 * juicyjones tears his own eyes out trying to get his Edimax dongle to work.
Dec 03 18:20:56 <Vaizki_> xbmc'ers should stick with raspi, atv etc
Dec 03 18:22:19 <juicyjones> Vaizki_ exactly
Dec 03 18:40:13 <APRichelieu> It seems like the function to create a new project fails.
Dec 03 18:40:36 <Kernle> I want ma serial cable :S
Dec 03 18:49:30 <Kernle> I somehow have the feeling that its all about the mkmmc-android.sh script. Because no distribution that uses this method works with my BBB :S
Dec 03 18:51:06 <Crofton|work> we are all booking the St Nick for FOSDEM?
Dec 03 18:51:12 <karl-s> this may be a pretty basic question but is the BBB onboard ethernet tied to the USB host mode ethernet in any way?
Dec 03 18:51:26 <Vaizki_> no
Dec 03 18:51:40 <karl-s> they are separate and distinct adapters from the BBB perspective?
Dec 03 18:54:00 <APRichelieu> You can of course run Ethernet on top of USB by loading g_ether
Dec 03 18:55:18 <Vaizki_> karl-s: yes, they are separate devices
Dec 03 18:56:03 <Vaizki_> and on default ångström build, the onboard ethernet runs dhcp client while the usb gadget ethernet runs dhcp server
Dec 03 18:56:31 <karl-s> Vaizki_, APRichelieu thx!
Dec 03 18:58:20 <Kernle> Hmm, is a 1A power supply enough for the BBB?
Dec 03 18:59:09 <karl-s> are you using any usb devices on it? wifi, sound, etc?
Dec 03 19:00:51 <juicyjones> Kernle http://www.amazon.com/gp/product/B00BLDH7XI/
Dec 03 19:01:31 <KotH> karl-s: the ethernet port on the bbb is a real network card with direct connection to the SoC core
Dec 03 19:01:45 <KotH> karl-s: no we-do-everything-over-one-slow-usb-port-rpi-thing
Dec 03 19:01:47 <Kernle> karl-s: HDMI, USB and Ethernet
Dec 03 19:02:17 <KotH> Kernle: how much power you need depends on how much power you need
Dec 03 19:02:25 <KotH> Kernle: you can run the bbb with <500mA
Dec 03 19:02:25 <karl-s> KotH, thx. i'm coming from the rpi world. I have a few home-made apps to migrate over...
Dec 03 19:02:49 <KotH> karl-s: oh.. welcome to the bbb then
Dec 03 19:03:04 <KotH> karl-s: as long as you dont do any graphics or video heavy stuff, you will love the bbb :)
Dec 03 19:03:23 <juicyjones> <-- also new and enthusiastically excited :)
Dec 03 19:03:32 <karl-s> yea, i wanted to do temperature but it was kinda complicated on the rpi due to the lack of analog gpio
Dec 03 19:04:36 <Defiant> karl-s: why didn't you used an i2c sensor?
Dec 03 19:04:48 <karl-s> dont know enough about them...
Dec 03 19:05:05 <karl-s> i'm not a very knowledgable electronics guy but i'm getting better
Dec 03 19:05:12 <Kernle> KotH: Yep. I made some power measurements yesterday. But just wanted to be sure. Maybe there are some powerpeaks when doing heavy stuff on system or smth...
Dec 03 19:05:26 <juicyjones> a weather station is the first project my GF wants to build with her RPI
Dec 03 19:06:04 <KotH> Kernle: check the TRM how much the SoC uses
Dec 03 19:06:14 <KotH> Kernle: the SRM should have some numbers too
Dec 03 19:12:10 <karl-s> i notice the getting started guide mentions updating Angstrom via SD, what about updating what is on the built in mmc card?
Dec 03 19:12:54 <Kernle> Thi sis done via SD karl-s
Dec 03 19:13:08 <juicyjones> karl-s it should say something at the middle or end about that. basically the same procedure, but you boot from SD, then image from there to emmc
Dec 03 19:14:22 <karl-s> using dd?
Dec 03 19:14:35 <juicyjones> xz
Dec 03 19:14:51 <juicyjones> in my case
Dec 03 19:14:55 <karl-s> kk
Dec 03 19:15:03 <juicyjones> but tar works fine too. just need the images
Dec 03 19:15:18 <juicyjones> once you get your head around the partitioning scheme it's pretty straightforward
Dec 03 19:15:41 <juicyjones> and the onboard is already partitioned correctly so no need for fdisk on that ever
Dec 03 19:19:38 <karl-s> What do you guys usually use for 'project boxes' if say I wanted a box with the BBB in it and a few separate relay boards
Dec 03 19:26:29 <Vaizki_> empty coconut shells
Dec 03 19:26:42 <Vaizki_> no wait that was for drinks
Dec 03 19:29:26 <Kernle> Hmmm... now for something different. I forgot to hold the user button while booting from SD. Okay... so that means my Angström wont boot when there is an SD card but it. Nvm that, but if I hold the user button, the board just does nothing. The power LED goes on, but thats it.
Dec 03 19:37:49 <juicyjones> Vaizki_ got some transistors with little umbrellas on them?
Dec 03 19:48:52 <prpplague> karl-s: what kind of relay boards are you using?
Dec 03 19:53:38 <karl-s> prpplague, just the cheap standard 2-relay like this one here: http://www.ebay.com/itm/4-Channel-5V-Relay-Module-With-Optocoupler-For-Arduino-DSP-AVR-PIC-ARM-/221297164601?pt=LH_DefaultDomain_0&hash=item338656c139
Dec 03 19:53:52 <karl-s> (or 4 channel relay in that instance)
Dec 03 19:56:34 <eslavko> Hello..
Dec 03 19:56:44 <eslavko> Someone here?
Dec 03 19:57:45 <eslavko> ...need to calibrate LCD3 cape on debian.
Dec 03 20:05:37 <eslavko> bye
Dec 03 20:05:38 <prpplague> karl-s: interesting
Dec 03 20:09:56 <juicyjones> Go me. \o/      I got ubuntu saucy booting off the emmc
Dec 03 20:18:01 <Kernle> Okay. Not even the TI Devkit boots from SD. Duh...
Dec 03 20:19:01 <Kernle> Any idea? Not one LED besides the power LED activates.
Dec 03 20:20:37 <juicyjones> most likely formated the sdcard wrong?
Dec 03 20:21:00 <juicyjones> Kernle did you use xz?
Dec 03 20:25:20 <Kernle> juicyjones: Nope. I did just use the sh file that comes with the TI devkit. Let me look up what it does
Dec 03 20:28:37 <Kernle> Nope, i see no xy. Just dd
Dec 03 20:29:20 <juicyjones> not sure. I was able to flash the default image, archlinux, ubuntu 12 and 13, but I didn't try anything else
Dec 03 20:35:24 <Kernle> Yeah, those work. They are just img files, which I can copy to the SD card with win32diskimager
Dec 03 20:35:59 <juicyjones> oh you're using windows
Dec 03 20:36:22 <Kernle> Windows and Linux both actually ;-)
Dec 03 20:36:25 <juicyjones> no idea how to make anything work that's not unix
Dec 03 20:37:02 <juicyjones> I only use Mac OS or unix for this kind of stuff. windows makes no sense, even with cygwin
Dec 03 20:37:35 <juicyjones> I mean Mac OS or linux*
Dec 03 20:42:43 <Kernle> Its also amazingly great how noone in #rowboat cares to answer my questions.
Dec 03 20:42:50 <Quinto> hi all.. i'm using an embedded board and i have create a .service for to start my app at boot: http://pastebin.com/sqcvg4wV but at start i have this error ttyUSB0 dont exist... if i do systemctl stop myservice and systemctl start myservice it work correctly.. Someone can help me? What i must insert in AFTER=
Dec 03 21:00:34 <karl-s> Quinto, add a sleep 30; in your init.d script
Dec 03 21:01:02 <Quinto> karl-s: mmmm
Dec 03 21:01:07 <Quinto> not is a good solution :D
Dec 03 21:01:46 <karl-s> i agree, but it sounds like your service is starting before usb is up
Dec 03 21:02:06 <karl-s> I think there is a way to change the order of startup
Dec 03 21:02:18 <karl-s> but i'm not familiar with how in angstrom
Dec 03 21:05:25 <Quinto> yes i must create an udev rules: read: https://lists.fedoraproject.org/pipermail/devel/2012-January/160917.html
Dec 03 22:17:58 <Quinto> for autostart my app at boot i must use only service?
Dec 03 22:18:09 <Quinto> in old kernel version i used rc.local
Dec 03 22:19:20 <BeagleGithub> [kernel] RobertCNelson pushed 1 new commit to 3.12: http://git.io/JrFJ9g
Dec 03 22:19:20 <BeagleGithub> kernel/3.12 54ea05e Robert Nelson: 3.12: update to v3.12.2...
Dec 04 01:44:47 <mark4> is it possible to disassebmle a binary file? like objdump -D but not on an elf?
Dec 04 01:45:22 <agmlego> Sure.
Dec 04 01:45:31 <agmlego> Especially if you know the format already.
Dec 04 01:45:31 <mark4> i dont have IDA pro lol
Dec 04 01:46:15 <mark4> how would i disassemble an arm binary in linux that is not an elf file
Dec 04 01:46:26 <mark4> its flat binary. i know its entry point and start address
Dec 04 01:47:25 <agmlego> Are there ARM disassemblers? Your question is more specific than I have knowledge on.
Dec 04 01:48:02 <agmlego> Seems to me, if you know the architecture and the entry/start points, you can just parse out the opcodes and parameters.
Dec 04 01:48:21 <agmlego> Essentially, writing your own disassembler.
Dec 04 01:48:54 <agmlego> That would at least get you to the assembly language. Making the jump from that to something higher, like C, is more difficult.
Dec 04 01:49:47 <juicyjones> ok basic embedded linux device question: on my BBB, there are no libraries, so do I actually install all the libraries to make the wifi driver I need?
Dec 04 01:50:10 <agmlego> Depends on the distro.
Dec 04 01:50:28 <juicyjones> i've got the ubuntu shiny for BBB on there atm.
Dec 04 01:50:29 <agmlego> Also, I highly doubt there are no libraries on your bone.
Dec 04 01:50:42 <agmlego> Yeah, that totally has libraries all over the place.
Dec 04 01:50:46 <juicyjones> hmm i'll pastebin something more specific, one sec
Dec 04 01:50:53 <juicyjones> good to know
Dec 04 01:53:56 <juicyjones> ok, just extracted a tarball of znc and did "./configure" on it
Dec 04 01:53:57 <juicyjones> http://pastebin.com/yY4TSdLf
Dec 04 01:53:59 <juicyjones> is the result
Dec 04 01:54:16 <agmlego> WHy are you installing znc from source? Is the package not new enough?
Dec 04 01:54:46 <agmlego> Also, config.log would be helpful.
Dec 04 01:54:53 <juicyjones> I am migrating a current 1.2 install over from another serve
Dec 04 01:54:55 <juicyjones> I have it
Dec 04 01:55:09 <agmlego> My guess is that you did not install the necessary headers and such first.
Dec 04 01:55:56 <juicyjones> likely. i've never installed this distro, usually the ubuntu stuff has all this on it.
Dec 04 01:55:56 <agmlego> Ubuntu, and debian-like systems in general, tend to have a build-essential package that brings in things like a C/C++ compiler, helpful header packagaes, and so on that are not installed by default.
Dec 04 01:56:11 <juicyjones> ok, lemme check aptitude
Dec 04 01:59:33 <juicyjones>  I knew that rang a bell. it's installing it now
Dec 04 01:59:41 <juicyjones> +1 agmlego  :)
Dec 04 02:00:27 <agmlego> Well, when the configure output says the C++ compiler cannot make binaries...that is generally an indication that there is no C++ compiler.
Dec 04 02:01:11 <agmlego> And since you said you had Ubuntu, and Ubuntu oes not come with any compilation stuff by default (that is what the package manager is or--Ubuntu is a binary distro after all), I added 1 and 5 and got 6.
Dec 04 02:04:22 * juicyjones 's cooking with gas now.
