Jul 23 05:49:14 <Rahul> hi
Jul 23 05:49:41 <Guest66268> hi
Jul 23 06:30:36 <buggerhead> what's uppppppppppppppppppppp
Jul 23 06:31:54 <tbr> everything that's not down
Jul 23 06:32:12 <buggerhead> good one
Jul 23 06:49:56 <Shadyman> jkridner: Nice Hack-a-day article ;) http://hackaday.com/2014/07/22/talking-beagleboard-with-jason-kridner/
Jul 23 09:33:01 <c10ud> hello, did anyone ever tried an usb webcam with bbb? i get garbled output...and google suggests (through rpi results) some kind of usb host drivers fuckup
Jul 23 09:33:29 <c10ud> i'm with rcn kernels, tested both 3.8 to 3.15
Jul 23 09:36:46 <tbr> c10ud: hard to say. might be a usb bandwidth issue, might be something else.
Jul 23 09:37:24 <tbr> the RPi has a very screwed up USB port, mind you. The MUSB on the beagle is just screwed up.
Jul 23 09:37:54 <tbr> c10ud: did you just fetch one frame or did you try something more advanced?
Jul 23 09:38:27 <c10ud> tbr, well I tried capturing a single frame, yuyv, at 1280x800
Jul 23 09:38:41 <c10ud> it shouldn't be an issue
Jul 23 09:39:33 <tbr> right, single frame should work
Jul 23 09:39:42 <tbr> tried the same on a linux desktop?
Jul 23 09:39:49 <c10ud> yup
Jul 23 09:40:31 <c10ud> actually I coded a little app on my own, tried on desktop, ok, tried on bbb, garbled output...then used one of those small utities to get a single frme..still garbled
Jul 23 09:41:15 <c10ud> https://groups.google.com/forum/#!category-topic/beagleboard/beaglebone-black/9OzPYEbLq4w
Jul 23 09:41:26 <c10ud> i posted it some days ago
Jul 23 09:48:59 <luastoned1> hey, does anyone here know a little more about iio drivers?
Jul 23 09:52:14 <jhn>  iio is what?
Jul 23 09:52:42 <luastoned1> industrial io
Jul 23 09:53:31 <jhn> Modbus, P0rofibus, ethercat, CAN?
Jul 23 09:54:51 <LetoThe2nd> jhn: no, ADC/DAC, things like that
Jul 23 09:54:52 <luastoned1> well I'm trying to run a dac at a high frequency and someone on here suggested to give that a shot
Jul 23 09:55:16 <tbr> c10ud: no idea then :/
Jul 23 09:55:58 <tbr> luastoned1: define high frequency
Jul 23 09:56:07 <luastoned1> 10-60k/s
Jul 23 09:57:53 <LetoThe2nd> luastoned1: just ask your specific question, instead of metaquestion-fishing for people who admit they've used IIO before.
Jul 23 09:58:30 <luastoned1> I want to know if the IIO system is capable of that
Jul 23 09:59:15 <luastoned1> on the BBB that is
Jul 23 10:01:34 <LetoThe2nd> 60kS might be tough, you' have about 10k cycles per value then.
Jul 23 10:01:49 <LetoThe2nd> a little more, just very rough numbers
Jul 23 10:03:30 <LetoThe2nd> from the feeling in my guts i'd say that without any additional load, and the system set up carefully 60kS might be doable. but i wouldn't rely on the system to do anything beyond that.
Jul 23 10:07:35 <XorA> BBB can do about 4 16 bit channels of audio at 48K, anything more and you start losing samples
Jul 23 10:07:43 <XorA> so you can use that as a guide
Jul 23 10:07:54 <LetoThe2nd> XorA: sounds about the same range, right.
Jul 23 10:08:23 <XorA> the problem is other subsystems start to take too long in atomic state after that point
Jul 23 10:08:31 <XorA> writing to SD card is a real problem
Jul 23 10:08:49 <av500> maybe PRU can help here?
Jul 23 10:09:06 <av500> XorA: got 4 ADCs hooked up?
Jul 23 10:09:24 <LetoThe2nd> XorA: yeah, RT folks once told me that 10^5 cpu cycles is about what you can expect from a usual PREEMPT_RT system, if its silicon was not optimized, but the kernel is rt-clean
Jul 23 10:09:29 <XorA> av500: I had 16 ADCs hooked up to beagle board for a project
Jul 23 10:09:36 <av500> nice
Jul 23 10:09:40 <av500> pics?
Jul 23 10:09:47 <av500> or $secret?
Jul 23 10:09:58 <XorA> av500: no longer have that board, and $secret$ as well :-(
Jul 23 10:10:03 <av500> ic
Jul 23 10:10:10 <av500> what interface?
Jul 23 10:10:18 <XorA> i2s
Jul 23 10:10:45 <av500> [11:58] <luastoned1> 10-60k/s
Jul 23 10:10:48 <XorA> the problem was not the audio interface that could keep up, there was just no time left to write it to SD or send it over network etc
Jul 23 10:11:03 <av500> right
Jul 23 10:11:13 <LetoThe2nd> yeah the problem is the other subsystems blocking
Jul 23 10:11:17 <av500> but one audio channel is already more than 10-60k/s
Jul 23 10:11:27 <av500> so that sounds easily doable
Jul 23 10:11:37 <av500> given you use an interface that DMAs
Jul 23 10:11:41 <av500> like e.g. I2S
Jul 23 10:11:54 <LetoThe2nd> av500: i2c is a stream optimized interface, he wants to use plain spi
Jul 23 10:12:03 <LetoThe2nd> (or she, that is)
Jul 23 10:12:04 <av500> SPI can DMA too, no?
Jul 23 10:12:17 <XorA> i2s is SPI with a sync clock, BTW :-D
Jul 23 10:12:32 <av500> its shift registers all the way down
Jul 23 10:12:51 <LetoThe2nd> of course i have no idea what additional protocol overhead the DAC in use needs.
Jul 23 10:13:05 <av500> DACs can be changed
Jul 23 10:13:11 <av500> or set on fire
Jul 23 10:13:36 <LetoThe2nd> in theory, yes.
Jul 23 10:13:36 <XorA> LetoThe2nd: just DACs then you just let them run
Jul 23 10:13:52 <XorA> SPI on omap3 is rated for 2mbits from memory
Jul 23 10:14:17 <av500> my memory of omap3 is fading
Jul 23 10:14:32 <LetoThe2nd> but as the original poster is very short on details, like type, number of bits, etc... we're all crystalballing here.
Jul 23 10:14:46 <av500> aint that the fun part?
Jul 23 10:14:57 <LetoThe2nd> partially
Jul 23 10:15:16 <LetoThe2nd> i'd rather be bowlingballing
Jul 23 10:31:29 <luastoned1> alright, sorry for being afk.. here is some more info: i'm trying to run a rgb laser with the bbb, the dac receives 6 16bit values (x, y, r, g, b, a)
Jul 23 10:33:19 <luastoned1> with just straight up c code I could get ~10k writes at the cost of maxing the cpu..
Jul 23 10:42:23 <notserpe> luastoned1: just curious what's the hardware exactly (laser/driver) i mean?
Jul 23 10:46:37 <av500> there was this guy as FOSDEM with a laser scanner
Jul 23 10:46:56 <av500> driven from USB audio I think
Jul 23 10:47:11 <av500> 4 channel, x,y,intensity and failsafe
Jul 23 10:48:37 <jkridner> Thanks Shadyman
Jul 23 10:49:41 <av500> https://www.youtube.com/watch?v=yEG68O6jpjo
Jul 23 10:50:04 <av500> he also talks at laser speed
Jul 23 10:50:36 <LetoThe2nd> well some minutes ago it was 60kS. now it is 6x60kS...
Jul 23 10:50:47 <av500> Ill go for lunch
Jul 23 10:50:54 <av500> lets see how much its when I am back
Jul 23 10:51:42 <av500> fun starts at 2:26
Jul 23 10:51:53 <LetoThe2nd> 6*2*60000 = 720kB/s payload
Jul 23 10:52:08 <av500> that is still nothing
Jul 23 10:53:09 <LetoThe2nd> yes, if you can do chunking and only have to get out the kB/s, its no problem.
Jul 23 10:53:20 <av500> VGA at 60fps is 36MB/s
Jul 23 10:53:22 <LetoThe2nd> if you have hard timing restraints... no idea.
Jul 23 10:53:26 <av500> and the BBB can output that
Jul 23 10:54:25 <LetoThe2nd> not sure comparing VGA to a standard spi is a good idea :P
Jul 23 10:54:49 <av500> its shiftregisters all the way down
Jul 23 10:54:58 <LetoThe2nd> hrhrhr
Jul 23 10:55:20 <av500> nobody forbids you to hook up SPI to the pixel clock of the LCD interface
Jul 23 10:55:35 <av500> and use the data lines as SPI data out
Jul 23 10:56:16 <av500> DMA over GPMC might do the same for you
Jul 23 10:56:18 <LetoThe2nd> yeah but you have multiple data lines, which intantly gives you that super cool higher MB/sec number.
Jul 23 10:56:51 <av500> 640x460x60fps is 18mbits/s
Jul 23 10:57:05 <av500> on every single bit
Jul 23 10:57:30 <av500>  /8 and you get 2MB/s
Jul 23 10:57:55 <LetoThe2nd> yeah.
Jul 23 10:58:06 <av500> http://bellard.org/dvbt/
Jul 23 10:58:18 <LetoThe2nd> so we have the solution: abuse VGA out for feeding the DACs :)
Jul 23 10:58:28 <av500> it worked in 2005
Jul 23 10:58:59 <av500> http://bellard.org/dvbt/
Jul 23 10:59:00 <av500> oops
Jul 23 10:59:03 <av500> http://www.erikyyy.de/tempest/
Jul 23 10:59:06 <av500> 2001 even
Jul 23 10:59:17 <LetoThe2nd> av500: dont know about 2005 or even 2001.. i'm still young, y'know?
Jul 23 10:59:42 <av500> yeah
Jul 23 10:59:53 <av500> ask your dad to tell you about that time
Jul 23 11:00:02 <av500> ok, lunch
Jul 23 11:00:11 <LetoThe2nd> an guadn
Jul 23 11:01:55 <vvu> how to
Jul 23 11:02:06 <vvu> how do i stop dmesg to throw to console the messages ?
Jul 23 11:04:33 <luastoned1> LetoThe2nd: du sprichst deutsch?
Jul 23 11:05:30 <luastoned1> notserpe: it's a swisslas rgb
Jul 23 11:06:06 <LetoThe2nd> luastoned1: depends. but in general, i do only support in english here so non-german speaker can also help and/or profit.
Jul 23 11:06:35 <luastoned1> LetoThe2nd: yeah sure - "an guadn" is halt sehr mundart
Jul 23 11:10:08 <av500> vvu: dmesg -n something
Jul 23 11:10:28 <av500> guden apo!
Jul 23 11:20:03 <luastoned1> av500: thanks for the suggestions.. im really not sure what would be the best way to approach this
Jul 23 11:25:05 <av500> do you need DC from the DAC?
Jul 23 11:26:06 <luastoned1> the DAC itself is powered, since the output goes straight to the laser
Jul 23 11:26:12 <av500> no
Jul 23 11:26:21 <av500> does the DC need to output down to DC?
Jul 23 11:26:53 <av500> e.g. the openlase guy used USB audio, audio DACs dont output down to DC usually
Jul 23 11:30:09 <luastoned1> Well, if I'm getting this right.. the DAC outputs +- 2.5V for RGB and +-10V for X/Y
Jul 23 11:30:22 <av500> yes
Jul 23 11:30:37 <av500> but that does not answer my question
Jul 23 11:31:02 <av500> does it need to go down to 0Hz aka DC
Jul 23 11:31:56 <luastoned1> alright, yeah it needs to
Jul 23 11:32:23 <av500> ok
Jul 23 11:41:12 <av500> luastoned1: what DAC do you have?
Jul 23 11:41:18 <luastoned1> homemade
Jul 23 11:43:50 <av500> ?
Jul 23 11:43:58 <av500> you made the chip yourself?
Jul 23 11:44:14 <luastoned1> no.. the board, let me pull the specs
Jul 23 11:55:22 <luastoned1> Okay so I'm using a TI DAC8554 and two TI 74AC244DW
Jul 23 11:55:45 <luastoned1> 16 / 2x 12bit
Jul 23 11:56:26 <av500> Low Power SPI™ Compatible Serial Interface with Schmitt-Triggered Inputs: Up to 50MHz
Jul 23 11:57:02 <luastoned1> Yeah, sounds about right
Jul 23 12:05:43 <luastoned1> in the end I'm looking for a way to drive the laser with either this (my already built dac, via spi) or any other way that the bbb can handle
Jul 23 12:05:44 <cityoflights2> Hi
Jul 23 12:05:49 <cityoflights2> I want to count the pulses as they come from this sensor:
Jul 23 12:06:00 <cityoflights2> http://davidegironi.blogspot.co.il/2012/11/avr-atmega-hall-effect-water-flow.html#.U8-RUdZ3TPQ
Jul 23 12:06:11 <cityoflights2> need I change the GPIO to edge?
Jul 23 12:06:31 <cityoflights2> can I poll the pin every 1ms, or should it be better to define it as an event?
Jul 23 12:06:45 <cityoflights2> I want to count 5 pulses and then stop the water flow
Jul 23 12:07:13 <xiqy> do I need the proprietary blob to play audio over hdmi on bbb?
Jul 23 12:07:45 <tbr> xiqy: should work out of the box on the standard images
Jul 23 12:09:27 <xiqy> tbr: do you know if the standard debian image is blob-free by default?
Jul 23 12:10:16 <av500> luastoned1: well, SPI is not much more than a clock and data line
Jul 23 12:10:19 <av500> and the right content
Jul 23 12:10:26 <av500> many ways to achieve that
Jul 23 12:10:32 <av500> we listed some today
Jul 23 12:11:16 <luastoned1> yeah I noticed, I'm really curious what would be the best in terms of stable output rate / cpu usage
Jul 23 12:12:07 <cityoflights2> av500, how do I count pulses?
Jul 23 12:12:43 <cityoflights2> they are at a rate of 6 per min
Jul 23 12:12:52 <av500> ultraspeed
Jul 23 12:12:54 <tbr> xiqy: I don't think there are any closed source bits on that, but you'll have to look through the image generation instructions to verify that.
Jul 23 12:14:12 <LetoThe2nd> cityoflights2: at 6/min just poll the line once a scond or so ;)
Jul 23 12:14:21 <av500> or connect to a 4 bit counter
Jul 23 12:14:28 <av500> and poll the 4 bits every minute
Jul 23 12:14:35 <LetoThe2nd> av500: ++
Jul 23 12:14:37 <av500> handle the rollover
Jul 23 12:14:39 <av500> done
Jul 23 12:16:03 <av500> 7493
Jul 23 12:16:42 <av500> 74590 for 8 bit
Jul 23 12:16:54 <av500> and check every 42 minutes....
Jul 23 12:19:21 <xiqy> tbr: thanks, I'll do that.
Jul 23 12:20:55 <cityoflights2> LetoThe2nd: does the BBB have a counter? can I set it up using device tree?
Jul 23 12:21:37 <LetoThe2nd> cityoflights2: ask av500 the counter was his idea :P
Jul 23 12:21:54 <av500> cityoflights2: WHAT?
Jul 23 12:22:07 <cityoflights2> while the pin had the edge cleared I pulled the value every sec and didn't see it change
Jul 23 12:22:42 <av500> google for 7493
Jul 23 12:23:03 <cityoflights2> this why I was thinking of using an event to trigger when a change happens
Jul 23 12:23:12 <cityoflights2> av500: yes
Jul 23 12:23:27 <cityoflights2> av500: I prefer to use the BBB
Jul 23 12:23:31 <cityoflights2> its easier
Jul 23 12:24:05 <cityoflights2> so, assume the negative pulse are short, I may miss them if I use a 1 sec poll rate
Jul 23 12:24:16 <cityoflights2> how to avoid this?
Jul 23 12:25:17 <cityoflights2> was thinking of using a capacitor and using the adc to find the average voltage
Jul 23 12:25:26 <av500> use a counter
Jul 23 12:25:30 <cityoflights2> ok ok
Jul 23 12:46:10 <newbr> hello  I'm using QT with beaglebone, how to read analog input in qt?
Jul 23 12:47:17 <av500> https://www.google.com/search?q=beaglebone+analog+in
Jul 23 13:40:15 <janki> hi
Jul 23 13:41:22 <janki> i want to know about beaglebone black?
Jul 23 13:42:06 <vvu> janki: beagleboard.org
Jul 23 13:42:16 <vvu> and questions here
Jul 23 13:42:56 <janki> i want to know about, how to write android os image into beaglebone internal memory
Jul 23 13:42:57 <janki> ??
Jul 23 13:43:52 <vvu> http://eewiki.net/display/AOA/BeagleBone+Black
Jul 23 13:46:41 <janki> vvu: how to write android os into internal memory not SD card??
Jul 23 13:47:32 <vvu> shouldn't it be the same procedure as SD card
Jul 23 13:49:05 <vvu> janki: http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide#Fastboot_and_eMMC
Jul 23 13:50:13 <janki> vvu: we can write android image into sd card by using card reader. but how to write image into BBB internal memory  ??
Jul 23 13:51:44 <janki> vvu: i mean how to write directly image into BBB controller ??
Jul 23 14:53:06 <ragnar76> hi all
Jul 23 14:53:58 <ragnar76> i've made a mistake layouting my pcb. is it possible to remap the pins using software?
Jul 23 14:54:42 <ragnar76> i mean i wanted to use p9.19 and p9.20 but my traces go to p8.19 and p8.20
Jul 23 14:55:34 <LetoThe2nd> "remap"?
Jul 23 14:55:58 <LetoThe2nd> if its gpios you use, you can use others. if its peripherals... probably no.
Jul 23 14:57:03 <ragnar76> not sure wha you mean with peripherals it's the i2c
Jul 23 15:02:35 <melonipoika> ragnar76, I think that you might be able to change the i2c pins by modifying the kernel device tree (if the p8 pins are not used by something else)
Jul 23 15:03:38 <melonipoika> check www.derekmolloy.ie, he has some good tables listing how the gpio pins are used
Jul 23 15:03:48 <LetoThe2nd> ragnar76: i2c is a peripheral.
Jul 23 15:03:56 <LetoThe2nd> ragnar76: it can be bitbanged, though ;)
Jul 23 15:04:40 <av500> also traces can be cut and wires soldered
Jul 23 15:04:50 <LetoThe2nd> av500: böring
Jul 23 15:05:33 <ragnar76> av500: i also cut layout a new pcb, tonertransfer it and do the acid stuff ;)
Jul 23 15:07:28 <ragnar76> also. strange thing is, i have this dht11 temp. and humity sensor. it does not work correctly on my bbb (false data) but on an atmega it does
Jul 23 15:08:33 <notserpe> [A
Jul 23 15:14:29 <ragnar76> rebuilding the dtc is much harder than rewirering or building a new pcb
Jul 23 15:32:43 <nathaniel_in_ks> Is the Debian distro as well supported as the Angstrom distro?
Jul 23 15:32:59 <nathaniel_in_ks> eg by the community.
Jul 23 15:35:19 <nathaniel_in_ks> Or, in other words, my board arrives today, and I am preparing the ssd card.  Which distro will give me the least headaches for a new user?
Jul 23 15:35:40 <jhn> What is the recommended method to adapt 5V SPI to the BBB 3V3 SPI.
Jul 23 15:36:11 <ragnar76> nathaniel_in_ks: if you allready are familiar with debian, take this one
Jul 23 15:36:58 <ragnar76> jhn: have a look
Jul 23 15:37:00 <ragnar76> http://www.exp-tech.de/Shields/Strom-Spannung-79/Sparkfun-Pegelwandler-Bidirektional.html?XTCsid=0041f8eb8aa6a2ac8485812cf36ee778
Jul 23 15:37:02 <nathaniel_in_ks> great, that is what I was hoping - actually I am most familiar with Ubuntu. Is that distro even better?
Jul 23 15:37:04 <jhn> nathaniel: I would do the first steps with the distro on board. Only after having aquainted with the board I would change the distro, else you cannot judge imprvement - or lack thereof.
Jul 23 15:38:13 <nathaniel_in_ks> jhn: thats true.  I have a lot of cloud server experience with ubuntu and I was hoping to be able to transfer my skills a bit.
Jul 23 15:38:35 <nathaniel_in_ks> debian seemed the closest to what I know.
Jul 23 15:38:59 <jhn> Yeah, tinker around and then change the distro. You can always revert.
Jul 23 15:42:29 <jhn> ragnar, mercie, was looking or an integrated chip for less soldering points.
Jul 23 15:43:52 <ragnar76> jhn: i german. ich hab mir das teil als ttl pegelwandler zugelegt. funktioniert wunderbar
Jul 23 15:46:08 <jhn> Si si, ho capito:-) Suche was für eine Platine, Hühnerfutter lötn finde ich immer so mühselig…Wir sollten englisch bleiben zum Nutzen aller.
Jul 23 15:47:51 <ragnar76> jhn: sure, it was much easier atm because we have a russian visitor here in our hackerspace and english is not my native lang
Jul 23 15:49:27 <jhn> :-)
Jul 23 15:53:06 <ragnar76> however, i used this level converter to speak with an atmega8 which sits on the pcb i was talking above
Jul 23 16:10:54 <nathaniel_in_ks> does the board have a way of updating itself or should I follow the instructions for burning a new sd card?
Jul 23 16:11:03 <nathaniel_in_ks> for angstrom
Jul 23 16:20:44 <gurki> https://learn.adafruit.com/beaglebone-black-installing-operating-systems/angstrom-faq
Jul 23 16:21:14 <gurki> 2s google oO
Jul 23 16:57:46 <nathaniel_in_ks> @trigpoint I read that.  It wasnt my question.
Jul 23 16:58:15 <trigpoint> Huh, what did I say?
Jul 23 16:58:20 <nathaniel_in_ks> @gurki sry I meant you.
Jul 23 16:59:16 <nathaniel_in_ks> My question is.  Can rhe os update itself once it is up and running (a better way to ask?)
Jul 23 17:00:16 <trigpoint> Am running wheezy and it certainly can, 'apt-get update' as root
Jul 23 17:00:30 <nathaniel_in_ks> ok, standard linux - cool.
Jul 23 17:22:11 <gurki> you will hardly find any distribution that does not have any method to update itself...
Jul 23 17:22:47 <gurki> i didnt quite get why "u can update it by doing blabla" doesnt answer the question "is it possible" :P
Jul 23 17:23:18 <nathaniel_in_ks> that was my thought but in the getting started section it talks about burning images rather than updating.
Jul 23 17:24:14 <gurki> u can do both. depending on ur needs
Jul 23 17:29:24 <nathaniel_in_ks> The board just arrived.  I now realize that it doesn't seem to come with a micro sd card with the os on it.  I am guessing that is what I was hung up on.
Jul 23 17:31:39 <jhn> BBB has two memories - onboard and flash. You can boot from either of the two.
Jul 23 17:31:54 <nathaniel_in_ks> ahhh
Jul 23 17:33:55 <nathaniel_in_ks> ok, that was actually very simple.  Those are some bright onboard leds
Jul 23 17:37:38 <vagrantc> the beagleboneblack is quite the 1GHz nightlight
Jul 23 17:57:00 <upwardindex> Any idea why the receiver is enabled on the TX pin of uart1 in BB-UART1-00A0.dts?
Jul 23 17:59:06 <xultz_> hi, I would like to knwo which command I use to write the Angstrom .img file to a sd card under Linux. I tried "dd bs=1M if=name_of_file.img of=/dev/sdb1" but the flashing procedure didn't work (following the Windows procedure, worked fine)
Jul 23 18:00:54 <beng-nl> xultz_: don't write to a partition (*1) but to a device
Jul 23 18:01:22 <agmlego> hjdyo'p
Jul 23 18:01:30 <agmlego> (er. sorry)
Jul 23 18:01:33 <xultz_> ah! that's ritgh! how dumb I am! I'll try it tonight, thank you very much!!!
Jul 23 18:02:01 <beng-nl> good luck :)
Jul 23 18:15:59 <upwardindex> Does 3.8.13 work in PREEMPT ?
Jul 23 18:29:19 <nandub> I have a beaglebone black that cannot boot from SD nor emmc I think I brick it.
Jul 23 18:29:54 <nandub> IS there anything I can do to try to fix it
Jul 23 18:30:19 <_av500_> prepare sd card
Jul 23 18:30:21 <_av500_> insert
Jul 23 18:30:30 <_av500_> power on with user button pressed
Jul 23 18:31:52 <nandub> _av500: you mean the boot button pressed?
Jul 23 18:32:13 <vvu> yes
Jul 23 18:32:21 <vvu> S2
Jul 23 18:33:12 <vvu> nandub: if you want to flash via usb check https://github.com/ungureanuvladvictor/BBBlfs
Jul 23 18:33:18 <nandub> I have been trying to do that since yesterday to no avail
Jul 23 18:33:38 <vvu> flashing via usb ?
Jul 23 18:33:59 <vvu> i pushed today a new version that supports the latest debian images
Jul 23 18:34:28 <nandub> No haven't try that because the instructions on the web were pretty old and difficult to do.  will try that github link
Jul 23 18:34:58 <vvu> if u have any issues please report them, i restarted working on the tool
Jul 23 18:37:59 <nandub> vvu: thanks I let you know how it goes
Jul 23 18:39:09 <vvu> nandub: you have the 4 gigs BBB ?
Jul 23 18:39:45 <nandub> No, I have revision A6A
Jul 23 18:40:01 <nandub> 4gb is revision C
Jul 23 18:40:04 <nandub> ?
Jul 23 18:40:07 <vvu> ok, i was just interested for a tester with 4 gigs BBB
Jul 23 18:40:11 <vvu> dunno
Jul 23 18:40:39 <nandub> ok
Jul 23 18:40:59 <nandub> so your repo may not work with this device version?
Jul 23 18:41:09 <vvu> with the 4 gigs one, need a tester :(
Jul 23 18:41:36 <vvu> nandub: wait 2 mins and then checkout the code, need to push a fix now
Jul 23 18:41:55 <nandub> ok
Jul 23 18:43:44 <vvu> nandub: pull now
Jul 23 18:44:11 <nandub> does you report works with debian from armhf.com site or the ones provided by beaglebone?
Jul 23 18:44:22 <nandub> I meant repo
Jul 23 18:45:12 <mistawright> hey guys can someone tell me what the default makeopts on a beaglebone black should be set to? I changed mine and cant remember now that i am no longer using distcc
Jul 23 18:45:16 <nandub> did a git pull a nothing got updates.  Did you push the fix?
Jul 23 18:45:26 <vvu> yes
Jul 23 18:45:33 <vvu> do a git stat
Jul 23 18:45:44 <vvu> and tell me the last commit message or commit hash
Jul 23 18:45:53 <vvu> git log sorry
Jul 23 18:46:58 <nandub> the last commit was 5 hours ago
Jul 23 18:47:10 <vvu> yes, i can see that...but I am on master
Jul 23 18:49:01 <nandub> I'm on master too
Jul 23 18:52:17 <nandub> my computer does not recognize when I plug USB cable and press S2
Jul 23 18:56:31 <nandub> I think my BBB is completely hose
Jul 23 18:57:08 <tpw_rules> i have a couple Qs: does the beaglebone black A6 support all sdhc and sdxc uSD cards? the bootloader can't recognize a partition table, can it?
Jul 23 18:59:40 <nandub> Never mind I think I case see the USB now, but my vbox is trying an error when it tries to connect to the BBB
Jul 23 19:01:45 <tpw_rules> so: vdd5v is the power coming in and sys5v is regulated?
Jul 23 19:02:18 <tpw_rules> ahh i see
Jul 23 19:10:50 <nandub> vvu: are you there?
Jul 23 19:13:08 <vvu> nandub: sorry internet down
Jul 23 19:13:27 <nandub> ok
Jul 23 19:13:33 <vvu> nandub: can you do dmesg and see what you have
Jul 23 19:13:35 <vvu> of lsusb
Jul 23 19:13:52 <vvu> and see if any Texas Instruments RNDIS appears
Jul 23 19:14:24 <nandub> I can see the BBB usb on my VBOX but cannot use it yet..  I just added a filter and rebooting to see if it let me use it
Jul 23 19:15:41 <nandub> I can see Texas Instruments AM335x USB but it keep telling me that is in use by something else.. my host is Mac OS X and guest ubuntu saucy
Jul 23 19:19:43 <nandub> vvu: the lsusb now show Texas Instrument Inc on the list
Jul 23 19:19:49 <vvu> that is good
Jul 23 19:19:58 <vvu> one sec let me see what is wrong with the git
Jul 23 19:20:36 <nandub> ok
Jul 23 19:25:00 <nandub> vvu: do your repo support flashing using the debian distro created by armhf.com?
Jul 23 19:25:15 <vvu> any flash
Jul 23 19:25:19 <vvu> it just does dd in the background
Jul 23 19:26:01 <vvu> try and run using the instructions on git now
Jul 23 19:26:03 <vvu> my connection is really bad
Jul 23 19:26:07 <nandub> yeah but recently the files distributed by armhf does not have img.gz files
Jul 23 19:26:36 <vvu> look in runscript.sh
Jul 23 19:26:43 <vvu> change the methoid i extract things
Jul 23 19:26:56 <nandub> I do not see changes on your repo
Jul 23 19:27:03 <nandub> or you havent?
Jul 23 19:27:21 <vvu> i cannot push them :(
Jul 23 19:28:02 <vvu> edit runscript.sh and change the command there
Jul 23 19:39:07 <vvu> nandub: pull now
Jul 23 19:41:18 <nandub> got it.
Jul 23 19:41:39 <nandub> usb_flasher says Something Wrong message
Jul 23 19:41:58 <vvu> it cannot open the device
Jul 23 19:42:02 <nandub> No such file or directory
Jul 23 19:42:22 <vvu> please be sure the BBB is connected to the VM
Jul 23 19:42:30 <vvu> after each step a new RNDIS interface comes up
Jul 23 19:42:36 <vvu> all of them must be forwarded to the VM
Jul 23 19:50:45 <upwardindex> Sending data over uart really messes up my gpio irq latency on 3.8.13-bone53 (the problem is not present on 3.2)
Jul 23 20:19:48 <nandub> vvu: are you still there?
Jul 23 20:20:17 <nandub> I can info on the dmesg
Jul 23 20:20:20 <nandub> see
Jul 23 20:20:39 <vvu> yes
Jul 23 20:20:40 <vvu> so what is happening now
Jul 23 20:23:12 <nandub> so when it runs usb_flasher it segfaults per the dmesg
Jul 23 20:23:31 <nandub> usb_flasher[1974]: segfault at 0 ip 00007f27724ab2f0 sp 00007fff5d289b58 error 4
Jul 23 20:24:17 <nandub> I can see rndis_host 2-2:1.0 usb0: register 'rndis_host' at usb-0000:00:06.0-2, RNDIS device, 9a:1f:85:1c:3d:0e on the dmesg
Jul 23 20:24:42 <vvu> can you give me the VID/PID of the device ?
Jul 23 20:25:42 <vvu> i did not try the stuff using a VM
Jul 23 20:25:54 <vvu> that is the root of the evil :)
Jul 23 20:26:18 <nandub> How do I get that?
Jul 23 20:26:44 <vvu> it should be in dmesg
Jul 23 20:26:52 <vvu> pastebin the log
Jul 23 20:28:09 <nandub> I will paste the tail of the file
Jul 23 20:30:21 <nandub> http://pastebin.com/90MmFGZu
Jul 23 20:31:32 <nandub> vvu: did you get the log?
Jul 23 20:31:56 <vvu> nandub: yes
Jul 23 20:32:04 <vvu> it breaks after the 1st libusb calls
Jul 23 20:32:40 <vvu> nandub: i cannot reproduce the bug, don't you have a native linux box ?
Jul 23 20:33:30 <nandub> No sorry, used too my two old laptops die so I do not have any
Jul 23 20:34:00 <vvu> :( i cannot reproduce this
Jul 23 20:34:16 <nandub> Do you have a vbox with linux in it?
Jul 23 20:34:25 <vvu> i have one at work
Jul 23 20:34:30 <vvu> 2morrow will be there and check
Jul 23 20:34:45 <nandub> ok
Jul 23 20:35:04 <nandub> It could be just my set up
Jul 23 20:35:37 <nandub> At least my BBB is not completely dead.  I was about to dump it when I remember IRC
Jul 23 20:35:47 <vvu> :)
Jul 23 20:36:18 <nandub> Thanks I'm going to go eat..
Jul 23 20:37:06 <nandub> if you want to keep in touch, go to my github/nandub page my email should be there
Jul 23 20:37:20 <vvu> nandub: perfect
Jul 23 20:37:52 <nandub> Thanks again for your help
Jul 23 20:38:08 <vvu> anytime
Jul 23 20:42:07 <upwardindex> Sending more than two characters to /dev/ttyO1 causes unacceptable latency on my irqs. Doesn’t the uart driver use dma?
Jul 23 20:42:14 <upwardindex> Anyone knows the name of the uart driver?
Jul 23 20:52:25 <nandub> vvu: I think I know the problem I was running the programs not inside the bin folder
Jul 23 20:53:01 <nandub> usb_flasher was failing because it could not find spl tool
Jul 23 20:53:45 <vvu> cd bin
Jul 23 20:54:00 <vvu> sudo ./runscript debian.img.xz or how your image is called
Jul 23 20:56:44 <nandub> uab_flasher is failing now with an out of memory error
Jul 23 20:57:23 <vvu> ok now i have no clue why this happens, today i tested on 3 machines and 2 other people tried the code
Jul 23 20:59:28 <nandub> where should I download the image from? location? armhf does not provide img.xz anymore
Jul 23 20:59:52 <vvu> change the runscript command
Jul 23 20:59:57 <vvu> i do xzcat there
Jul 23 21:01:40 <nandub> I will download the one from beagleboard I found them
Jul 23 21:02:57 <nandub> can I use this one http://debian.beagleboard.org/images/BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz
Jul 23 21:03:58 <vvu> no, use the normal one not the flasher
Jul 23 21:04:19 <vvu> http://debian.beagleboard.org/images/bone-debian-7.5-2014-05-14-2gb.img.xz
Jul 23 21:10:12 <nandub> ok
Jul 23 21:18:51 <nandub> I think it is the way I'm trying to use this.  I don't think your repo will work over a VM.
Jul 23 21:19:23 <vvu> i will use a VM tomorrow maybe i can push more fixes
Jul 23 21:20:25 <nandub> I increate the CPU and memory on my box and I still get the Out of Memory, but I can see if trying to do something with the USB because I saw a name RNSDIS or something like that..
Jul 23 22:56:36 <MrYaah> could I get some help figuring out the correct way to enable the uart serial ports on the beaglebone black?
Jul 23 22:56:43 <MrYaah> I managed to get it to work using "echo BB-UART1 > /sys/devices/bone_capemgr.*/slots"
Jul 23 22:56:57 <MrYaah> but having a script that just runs that command on startup seems like a hack
Jul 23 23:07:46 <veremit> MrYaah - you can add something that fakes the capemgr in your uEnv.txt .. something like capemgr.enable=BB-UART1 iirc
Jul 23 23:38:34 <DrDaemonEye> I am curious to know what the maximum input voltage for any one pin on the beaglebone black is.  I thought I read somewhere it was 1.8v, but I cannot find the source again
Jul 23 23:43:04 <veremit> check the Beagle System Reference Manual
Jul 23 23:43:37 <DrDaemonEye> thanks
Jul 24 02:10:56 <ryanneufeld> the USER/BOOT button is the one nearest the SDCard slot, corret?
