**** BEGIN LOGGING AT Fri Nov 22 03:00:00 2013
Nov 22 03:00:17 <frege> we had this conversation last night for an infrared photodiode
Nov 22 03:00:27 <frege> it used to work but it doesn't now
Nov 22 03:10:08 <frege> I'm getting 1 all the time
Nov 22 03:16:47 <NovaKitty> I've used DD to copy the second (rootfs) partition from a SD card to the first partition of a USB hard drive.  What file to I edit on the sd card to force it to use the USB drive for the root filesystem instead of the SD card?  This is the Debian armhf image.
Nov 22 03:19:57 <vagrantc> which Debian armhf image?
Nov 22 03:21:05 <NovaKitty> the one from armhf.com
Nov 22 03:21:21 <NovaKitty> wheezy
Nov 22 03:21:31 <vagrantc> in any case, you'd need to pass root= on the boot prompt ... possibly in uEnv.txt?
Nov 22 03:23:21 <frege> guys
Nov 22 03:23:24 <frege> can someone help me here?
Nov 22 03:25:04 <jonpry> it just can't work like that
Nov 22 03:25:22 <jonpry> IR diode is going to have a reverse voltage of < 1V
Nov 22 03:25:49 <thews> frege if I remmeber from last night you had just the resistor on one side of the sensor instead of resistor on one side having one end on the ground (pulldown) or the other end on 3.3v (pullup)
Nov 22 03:26:35 <frege> thews: yeah; did you see the circuit?
Nov 22 03:26:47 <NovaKitty> vagrantc: thank you
Nov 22 03:26:47 <thews> I think I did but you showed the resistor in series
Nov 22 03:26:53 <thews> instead of T-d off
Nov 22 03:26:56 <vagrantc> NovaKitty: did you find what you needed?
Nov 22 03:27:11 <frege> thews: this one? http://flockdraw.com/cvumwa
Nov 22 03:27:31 <NovaKitty> vagrantc: I think youre right, I'm just looking for some examples to make sure
Nov 22 03:27:41 <jonpry> short pin is anode?
Nov 22 03:28:06 <NovaKitty> vagrantc: I did this with a Pi and it was the same thing pretty much but a different file
Nov 22 03:28:44 <frege> thews: ?
Nov 22 03:29:50 <Sakai> We are Japan IT company, we would like to buy 2pcs of beaglebone black Revision A6. where can we buy?
Nov 22 03:30:11 <thews> frege: I would think you would need 3.3v on one side of the sensor by itself, and then the other side going to the pin to your input pin, and then a T off on the input pin that has a resistor and then to ground
Nov 22 03:30:45 <frege> thews: would you draw it for me?
Nov 22 03:30:50 <thews> because the diode needs enough forward voltage to cross the PN junction
Nov 22 03:31:24 <frege> let me try
Nov 22 03:32:29 <NovaKitty> Sakai: Beagleboard.org, if you click the buy button, it presents you with a list of vendors you can buy from.  I would see if you can find one of these that is in Japan or ships to Japan
Nov 22 03:33:09 <thews> frege: http://new.dave-auld.net/images/stories/Arduino/BasicIO/AnalogIn-PhotoResistor.jpg
Nov 22 03:33:28 <Sakai> now all is revision A6?
Nov 22 03:33:49 <NovaKitty> I got mine from Makershed in California, USA..it is rev R6
Nov 22 03:34:04 <Sakai> thank you.
Nov 22 03:34:50 <thews> frege: another http://www.me.umn.edu/courses/me2011/arduino/technotes/photocell/schem1.gif
Nov 22 03:35:25 <thews> of course for you the voltage will be 3.3v for digital pins, and resistor value could be different depending on the resistance measured across the photoresistor
Nov 22 03:36:16 <thews> http://www.bristolwatch.com/arduino/img/photores.jpg examples of pull down and pull up
Nov 22 03:37:06 <frege> thews: what do you suggest for resistance?
Nov 22 03:37:12 <frege> 10kohm?
Nov 22 03:37:26 <thews> if you have some choices I'd start with maybe 1k or 3k
Nov 22 03:37:36 <thews> unless you have a spec sheet on the sensor
Nov 22 03:37:47 <thews> multimeters take away all of the guesswork
Nov 22 03:38:36 <frege> I will buy one
Nov 22 03:39:04 <thews> you can measure the individual sections of resistance
Nov 22 03:39:33 <thews> at one point the photo resistor should have more resistance than the resistor
Nov 22 03:39:38 <thews> and otherwise have less
Nov 22 03:39:53 <thews> electricity takes the path of least resistance
Nov 22 03:40:14 <thews> depending on the exposure to light
Nov 22 03:41:09 <frege> interesting
Nov 22 03:41:26 <thews> view the photo resistor as a potentiometer
Nov 22 03:41:31 <thews> it's just a variable resistor
Nov 22 03:41:53 <thews> what changes it's resistance is the exposure to what it is sensitive to
Nov 22 03:41:54 <myself> but with only two leads, so you need to pair it with a fixed resistor to get a useful potentiometric output.
Nov 22 03:41:57 <thews> that's what makes it a ssensor
Nov 22 03:42:11 <myself> "potential" is another term for "voltage", by the way. A potentiometer is a voltage divider.
Nov 22 03:42:12 <frege> I had this shit working and it made total sense to me and I got what was what
Nov 22 03:42:22 <jonpry> photodiode != photoresistor
Nov 22 03:42:48 <thews> photodiode allows electricity to flow based on forward current
Nov 22 03:43:12 <jonpry> photodiode is a solar cell, it makes power
Nov 22 03:43:23 <thews> not necessarily
Nov 22 03:43:36 <frege> it's not working
Nov 22 03:44:27 <thews> there are photo diodes that just behave as diodes but have properties to make the PN junction gap lessened
Nov 22 03:44:33 <frege> this is an infrared sensor
Nov 22 03:45:00 <frege> 300nm to 1100nm
Nov 22 03:46:02 <jonpry> that isn't really sufficient to say what it is
Nov 22 03:46:29 <frege> jonpry: PT481
Nov 22 03:46:44 <frege> jonpry: P/N: OPTIC-001484
Nov 22 03:47:08 <frege> jonpry: Photo Transistor Dar. Peak(800nm) 400nm-1000nm
Nov 22 03:47:13 <frege> that's the exact specs
Nov 22 03:47:40 <frege> H.Sen Ic: 10mA    Vce(sat):0.7V
Nov 22 03:47:48 <jonpry> yeah phototransistor
Nov 22 03:48:00 <thews> all different things
Nov 22 03:48:10 <frege> so how do I get its value?
Nov 22 03:48:15 <frege> I need a pullup resistor
Nov 22 03:48:40 <frege> between VDD3.5 and longer pin of phototransistor right?
Nov 22 03:48:54 <frege> what should be the resistance?
Nov 22 03:49:02 <frege> I got all sort of resistors in front of me
Nov 22 03:49:16 <frege> from 0 to 1Mohm
Nov 22 03:49:33 <jonpry> i think you have it backward
Nov 22 03:49:46 <jonpry> short lead is the collect and it's pnp device
Nov 22 03:49:53 <jonpry> *collector
Nov 22 03:50:13 <frege> ahh shit
Nov 22 03:51:09 <thews> http://www.flickr.com/photos/61351883@N06/5846338891/
Nov 22 03:51:42 <frege> jonpry: so far VDD -----/\/\10kohm/\/\------(long-leg)(phototransistor)(short-leg)-------?
Nov 22 03:51:46 <frege> what's ?
Nov 22 03:52:06 <jonpry> gnd
Nov 22 03:52:10 <thews> http://dgraves.org/mailboxmonitor
Nov 22 03:52:20 <thews> looked like the long leg was ground on there
Nov 22 03:52:23 <thews> have to get some rest
Nov 22 03:52:27 <frege> weird
Nov 22 03:52:35 <frege> jonpry: what about the input pin?
Nov 22 03:52:58 <jonpry> wait
Nov 22 03:53:29 <jonpry> long leg is gnd
Nov 22 03:53:43 <jonpry> short leg is 10k to 3.3V
Nov 22 03:53:59 <jonpry> input is short leg
Nov 22 03:56:07 <frege> fuck it trurned off
Nov 22 03:56:19 <frege> hopefully nothing burned out
Nov 22 03:58:08 <Dr{Wh0}> http://hades.mech.northwestern.edu/index.php/Photodiodes_and_Phototransistors
Nov 22 04:00:02 <NovaKitty> vagrantc: Ok I'm looking at my uEnv.txt...It looks complicated.  I pasted it here - http://pastebin.com/0ZyYEpd0.  I see a line that looks to me like it sets a variable for "mmcroot" and its set to mmcblk0p2, which is the current rootfs.  Is this where I should plug in /dev/sdb1?
Nov 22 04:01:00 <NovaKitty> It looks to me like its checking for a SD card, booting from it if present, otherwise booting from the eMMC.
Nov 22 04:02:40 <vagrantc> NovaKitty: sounds promising
Nov 22 04:03:16 <frege> Dr{Wh0}: good link! thanks man!
Nov 22 04:03:18 <vagrantc> you could set up your own uEnv.txt and put it on an sdcard, probably
Nov 22 04:04:02 <frege> Dr{Wh0}: do you know what's RE http://hades.mech.northwestern.edu/images/8/82/Phototransistor_amplifiers.png
Nov 22 04:04:14 <frege> what does E stand for there?
Nov 22 04:04:37 <vagrantc> NovaKitty: just putting it on an SD card will allow you to revert back easily.
Nov 22 04:07:16 <Dr{Wh0}> Emitter resistance and Collector resistance.
Nov 22 04:09:14 <frege> I don't think that pullup resistor should connect to ground
Nov 22 04:09:17 <frege> doesn't make sense
Nov 22 04:10:04 <Dr{Wh0}> its not actually a pullup its a bias resistor for the transistor cicruit.
Nov 22 04:11:13 <NovaKitty> vagrantc: yeah i guess i can try.  I can edit the fat boot partition from anything.
Nov 22 04:12:19 <Dr{Wh0}> frege: to act as a switch I think your goal then you want a higher resitance value otherwise it is just an amplifier and is used to measer to amount of light.
Nov 22 04:12:49 <frege> Dr{Wh0}: I want to measure the amount of light if it's possible
Nov 22 04:12:57 <frege> Dr{Wh0}: how can I do that?
Nov 22 04:13:30 <Dr{Wh0}> oh.. ok. lower restance value will give you an output of voltage you can measer with a AtoD circuit.
Nov 22 04:14:06 <Dr{Wh0}> <5k but not too low where it will burn out the transistor 2-5k should be right dont go lower than 1k
Nov 22 04:15:02 <frege> I will go 3.3k
Nov 22 04:15:21 <frege> Dr{Wh0}: how can I measure it?
Nov 22 04:15:28 <frege> I'm using P8_10
Nov 22 04:17:03 <frege> Dr{Wh0}: can you give me a circuit please?
Nov 22 04:17:07 <Dr{Wh0}> and A/D converter but a multimeter will do to test.
Nov 22 04:17:31 <Dr{Wh0}> measure your voltage at Vout.
Nov 22 04:18:14 <frege> Dr{Wh0}: http://stuffwemade.net/post/beaglebone-pinout
Nov 22 04:18:18 <frege> where is Vout
Nov 22 04:18:46 <Dr{Wh0}> oh.. no i ment vout from the circuit. on that page I posted.
Nov 22 04:18:58 <frege> which one?
Nov 22 04:19:01 <frege> ahah
Nov 22 04:19:05 <Dr{Wh0}> does the bbb have an a/d? probably.
Nov 22 04:19:19 <frege> hope so
Nov 22 04:20:05 <Dr{Wh0}> to measure the low to high level use the Commond-Collector Amplifier bigger voltage = more light.
Nov 22 04:20:30 <NovaKitty> vagranc: it looks like the change had no effect.  The BBB booted normaly to the SD card.  I went to "File System" in in the file manager and the capacity indicates it's still the sd card.
Nov 22 04:20:52 <frege> Dr{Wh0}: yeah I made it
Nov 22 04:20:58 <frege> but I'm getting 0
Nov 22 04:21:08 <Dr{Wh0}> http://beaglebone.cameon.net/home/reading-the-analog-inputs-adc
Nov 22 04:24:25 <frege> naaah something is fucked
Nov 22 04:24:40 <Dr{Wh0}> we sure its a photo trans not a diode?
Nov 22 04:24:54 <frege> Dr{Wh0}: what if it's a diode?
Nov 22 04:25:01 <frege> I mean they could label it wrong
Nov 22 04:25:06 <Dr{Wh0}> it will produce a very low signal needing aplification.
Nov 22 04:25:13 <frege> I pasted the label
Nov 22 04:25:27 <Dr{Wh0}> datasheet?
Nov 22 04:25:33 <frege> >>> GPIO.input("P9_39")
Nov 22 04:25:33 <frege> 0
Nov 22 04:25:37 <frege> I keep getting 0
Nov 22 04:26:00 <Dr{Wh0}> dont test with the BBB yet. you will break it :)
Nov 22 04:26:06 <Dr{Wh0}> use a volt meter.
Nov 22 04:27:03 <frege> Dr{Wh0}: http://www.tel.uva.es/personales/tri/pt481-e.pdf
Nov 22 04:27:14 <frege> Dr{Wh0}: I think I've burned this one
Nov 22 04:27:17 <frege> gonna use another one
Nov 22 04:27:29 <frege> it's cheap though 0.98$
Nov 22 04:27:47 <frege> gonna be back in 30 mins
Nov 22 04:29:26 <Dr{Wh0}> they give you a test circuit and test values use those and test.
Nov 22 04:35:21 <Dr{Wh0}> needs an input resistor to limit current or POOF <50m can go as high as 6v but i think you are doing 3v3? so use the drawing in that schematic but put a limiting resitore on Vcc you can calculate it to get your ~20ma 150ohm at 3v3
Nov 22 04:35:41 <Dr{Wh0}> too late for this math. im out.. need food and zzz night all.

Nov 22 07:42:12 <Freddie_> HI all
Nov 22 07:44:02 <Freddie_> How can I read the "value" content of more gpio and collect them to form a binary string  with a single command (or script)??
Nov 22 07:44:45 <Freddie_> (perhaps more of a shell question than a beagle specific one...)
Nov 22 07:45:50 <Nedlinpopo> Has anyone fully understood the BBB USB problems yet?
Nov 22 07:46:24 <Nedlinpopo> I've seen many things suggesting noise/EMI on the data lines
Nov 22 07:46:29 <viv__> hi
Nov 22 07:46:39 <Nedlinpopo> and core voltage switching etc.
Nov 22 07:46:44 <Nedlinpopo> viv__: hello

Nov 22 10:13:51 <Uninstall_> av500: no sd card
Nov 22 10:15:11 <Uninstall_> av500: If I press reset I get this: "CCCCCCCC" printed out on minicom
Nov 22 10:18:30 <Uninstall_> av500: do I need to have u-boot on my SD card?
Nov 22 10:22:07 <av500> er yes
Nov 22 10:22:17 <av500> CCC is the ROM code begging to be fed with data

Nov 22 11:13:47 <ragnar76> anyone has an idea why mp3s are not playing on a bbb using mplayer? i mean, they play but i have no hearable output
Nov 22 11:14:02 <av500> over hdmi?
Nov 22 11:14:12 <av500> connected to?
Nov 22 11:14:17 <ragnar76> av500: no, an usb soundcard
Nov 22 11:14:37 <ragnar76> it plays wav, flac, ogg, ... fine but not mp3s
Nov 22 11:14:39 <av500> alsamixer?
Nov 22 11:14:42 <av500> oh
Nov 22 11:15:02 <av500> maybe you dont have the patent license?
Nov 22 11:15:50 <ragnar76> a license? with mplayer?
Nov 22 11:16:26 <av500> :)
Nov 22 11:16:29 <priyanka> hello
Nov 22 11:18:41 <av500> ragnar76: run with -vvv and see difference between mp3 and wav
Nov 22 11:23:44 <av500> ragnar76:  try -ao pcm and try to play the pcm file
Nov 22 11:24:09 <av500> priyanka: ask here
Nov 22 11:24:16 <av500> or send money
Nov 22 11:24:26 <av500> why would I answer you in pm?
Nov 22 11:25:00 <ragnar76> av500: -ao pcm does not work either
Nov 22 11:25:18 <av500> but it works for e.g flac?
Nov 22 11:25:24 <av500> what is the error?
Nov 22 11:25:34 <av500> mplayer from angstrom feed?
Nov 22 11:25:53 <ragnar76> gnarf, -ao pcm writes a wav file. i was expecting sound :/
Nov 22 11:26:08 <ragnar76> so, it works
Nov 22 11:26:44 <av500> the wav file works?
Nov 22 11:26:51 <av500> hmm
Nov 22 11:26:54 <ragnar76> but, the audiodump is pure silence
Nov 22 11:26:57 <av500> ah

Nov 22 11:34:37 <janne> ragnar76: please try mplayer --ac=ffmp3
Nov 22 11:40:52 <av500> ragnar76: try another mp3 file?
Nov 22 11:40:55 <av500> not John Cage
Nov 22 11:43:32 <janne> or at least a different track than 4'33"
Nov 22 11:43:42 <ragnar76> that works!
Nov 22 11:45:18 <janne> what? --ac=ffmp3?
Nov 22 11:45:54 <ragnar76> yes, that works
Nov 22 11:47:20 <priyanka> hi this is priyanka a student from India, having interest on embedded systems domain. I got introduced to BBB and by far my experience with BBB is enriching, I would like to take this experience forward and try and understand things in more depth. In this journey of my learning I would like to be associated with one of you geeks and take my learning to the next level. please let me know if I can be associated with one of you
Nov 22 11:47:36 <av500> no

Nov 22 11:59:11 * suihkulokki notes the beaglebone sd card formatting script was written by XorA 
Nov 22 12:00:29 <av500> yes
Nov 22 12:00:37 <av500> including the magic values
Nov 22 12:04:44 <XorA> magic values?
Nov 22 12:05:21 <ogra_> abracadabra factor
Nov 22 12:06:20 * XorA does not remember any magic
Nov 22 12:07:21 <suihkulokki> looks remarkably less magical than many of the other "oh we need something to make bootable sd card" scripts I'm checking
Nov 22 12:09:20 <XorA> denix: is to blame for any magic anyway, I just scripted it
Nov 22 12:21:25 <av500> echo ,9,0x0C,*

Nov 22 13:13:28 <Sam___> I build new Angstrom based image for BeagleBone black as per steps on eLinux.org but only user LEDs on BBB working .It is not detected by PC like with factory image ?
Nov 22 13:13:49 <av500> do you have a serial cable?
Nov 22 13:13:56 <Sam___> No
Nov 22 13:14:46 <Sam___> I just delete uImage-3.8.13 and replace  it with my uImage
Nov 22 13:15:40 <av500> well networking is hard to debug if you are blind
Nov 22 13:15:57 <av500> when you put back the uimage it works again?
Nov 22 13:16:42 <Sam___>  if I put original uImage its again work fine
Nov 22 13:17:46 <Sam___> Its user LEDs are blinking propery with new uImage but can't access via PC
Nov 22 13:19:17 <Sam___> hello
Nov 22 13:20:40 <KotH> echo
Nov 22 13:22:01 <Sam___> So what to do now ? Can use normal USB cable for serial debugging ?
Nov 22 13:22:38 <KotH> yes, yo can use a normal 3.3V serial2usb usb cable for serial debugging
Nov 22 13:24:47 <Sam___> 3.3 v means ? can I use only GND,USB+,USB- as GND.RX,TX for that in case of normal USB wire ?
Nov 22 13:26:05 <av500> no
Nov 22 13:26:09 <av500> 6 pin serial header
Nov 22 13:26:15 <av500> you need a usb2ttl cable
Nov 22 13:26:22 <av500> like $5 on ebay
Nov 22 13:31:40 <sam___> Can we delete factory uImage of BeagleBone black and replace it with newly build Image to verify it ?
Nov 22 13:32:47 <KotH> nope, we cannot do that
Nov 22 13:33:00 <KotH> you can't for obvious reasony, and i dont own a bbb
Nov 22 13:33:05 <KotH> reasons*
Nov 22 13:33:11 * KotH no typy today
Nov 22 13:33:22 <KotH> and not enough chocolate too
Nov 22 13:34:05 <sam___> No I am talking about SD card Image
Nov 22 13:34:38 <KotH> I dont talk, i type
Nov 22 13:34:54 <sam___> ok sorry
Nov 22 13:36:10 <sam___> because I delete uImage in SD card and replace it with new uImage but only user LEDs blinking but BBB is not detected by PC ?
Nov 22 13:36:43 <KotH> if you want answers, ask specific quesitions... not roundabout general questions, nobody feels inclined to answer because it is not clear what kind of answer you'd expect
Nov 22 13:37:02 <KotH> read the link in the topic for more informations on this
Nov 22 13:37:32 <sam___> which link ?
Nov 22 13:37:33 <av500> one can replace uimage of course
Nov 22 13:37:37 <av500> but it can also go wrong
Nov 22 13:37:42 <av500> image could be bad
Nov 22 13:37:45 <av500> wrong filename
Nov 22 13:37:51 <av500> etc
Nov 22 13:37:57 <av500> without serial, you are blind
Nov 22 13:38:03 <av500> so check again all steps you did
Nov 22 13:38:11 <av500> but not much we can help from here
Nov 22 13:38:23 <sam___> No I put same name as uIMAGE-3.8.13
Nov 22 13:38:25 <av500> I hate the fact that BBB has no serial out of the box as much as you
Nov 22 13:40:56 <sam___> Sorry but I am new to all this .And thanks for your everything.Bye !!
Nov 22 13:45:36 <jonand> BBB = eternal september
Nov 22 13:46:54 <KotH> no, september ended with the usenet
Nov 22 13:47:32 <IamTrying> http://beagleboard.org/Products/BeagleBone%20Black - I have this Beagle board. It has 46 pin headers. On which pins i can take out the VGA for monitor? and which pins i can take out to make microphone in and speaker output?
Nov 22 13:47:54 <av500> on no pin
Nov 22 13:47:58 <av500> it does not have VGA
Nov 22 13:48:04 <IamTrying> Oh my god??? av500
Nov 22 13:48:09 <IamTrying> NO VGA"???
Nov 22 13:48:14 <av500> nor does it have mic or speaker
Nov 22 13:48:18 <av500> it has HSMI
Nov 22 13:48:21 <av500> HDMI
Nov 22 13:48:27 <KotH> IamTrying: tune it down. av500 might be big, but he hasnt reached god status yet
Nov 22 13:48:33 <av500> you can add an audio cape for audio in/out
Nov 22 13:48:55 <av500> its 2013, vga is kinda antique :)
Nov 22 13:49:42 <IamTrying> av500, KotH , very confused and nervous now i thought i can with those 46x2 pins? i need to make VGA because my all screens are VGA only (Touch screen) and i have head phone mic/speaker how can i do this 3 options with this board please?
Nov 22 13:50:06 <av500> audio cape for audio
Nov 22 13:50:10 <av500> for VGA, there is no cape
Nov 22 13:50:17 <Russ> IamTrying, depending on how much room you have, there are devices that translate a hdmi signal into audio and vga
Nov 22 13:50:27 <av500> https://www.google.com/search?q=beaglebone+VGAy
Nov 22 13:50:35 <av500> Russ: that cost more than the beagle
Nov 22 13:50:44 <av500> http://makezine.com/2010/01/27/adding-vga-output-to-a-beagleboard/
Nov 22 13:50:59 <av500> https://www.google.com/search?q=beaglebone+VGA
Nov 22 13:51:43 <IamTrying> Russ, its too expensive then, if i have to add always new device extra on top of beagle (wanted to achieve in low cost)
Nov 22 13:51:48 <Russ> av500, actually a whole penny less
Nov 22 13:51:50 <IamTrying> Thank you av500 , Great
Nov 22 13:52:03 <av500> thank larry and sergey
Nov 22 13:52:09 <av500> I just used their website
Nov 22 13:53:05 <IamTrying> YES - thats what i mean man, if this works would be GREAT GREAT https://lh4.googleusercontent.com/-i96yPJMb4ic/T-cTXz5lJxI/AAAAAAAACVI/3-FUUQonV6s/s1600/DSCF2395.JPG
Nov 22 13:53:19 <av500> so go for it
Nov 22 13:54:05 <av500> ah right, ladder DAC on the LCD signals
Nov 22 13:54:16 <av500> actually fairly simple
Nov 22 13:54:33 <KotH> and cheap too
Nov 22 13:54:47 <KotH> apropos... need to write some mail to get some stuff for free
Nov 22 13:54:54 <av500> CC me
Nov 22 13:54:55 <av500> :)
Nov 22 13:54:56 <KotH> av500: thanks for the reminder ;)
Nov 22 13:55:01 <IamTrying> YES - Guru av500 . Last confusion, how can i receive Arduino pin signals in the Beagle boards? In my Arduino i have 3V, 5V, Gnd, Pin 1 , 2 is it possible to do the same ?
Nov 22 13:55:02 <KotH> *g*
Nov 22 13:55:02 <av500> ask for 2
Nov 22 13:55:18 <KotH> av500: i already plan to ask for 2, one for mranostay and one for me :)
Nov 22 13:55:22 <av500> IamTrying: BBB is also 3.3V
Nov 22 13:55:27 <av500> meh
Nov 22 13:55:32 * av500 is sad now
Nov 22 13:55:44 <IamTrying> Guru av500 , if i do not use Arduino + its Relay, can i use them in the Beagle Board (by not using Arduino i mean straight to the Beagle Board) ?
Nov 22 13:55:54 <KotH> av500: you got your barcelona-eltoro mug
Nov 22 13:56:04 <KotH> av500: and i didn't get your daughter
Nov 22 13:56:48 <av500> u so cruel
Nov 22 13:56:53 <KotH> me?
Nov 22 13:56:58 <KotH> you didnt pay me!
Nov 22 13:58:15 <av500> ...The Linux guys are likely frowning on my lack of guru-ishness while the BeagleBone guys are probably counting how long it will take for my setup to catch on fire....
Nov 22 13:58:18 <av500> nice
Nov 22 13:58:44 <av500> KotH: I have a stack of Milka with your name on it here
Nov 22 13:58:49 <honestly> is there a simple way to get something with a glibc and armhf or armel running in qemua
Nov 22 13:58:59 <av500> no idea
Nov 22 13:59:00 <honestly> or something similar
Nov 22 13:59:07 <av500> ask in #qemu maybe?
Nov 22 13:59:10 <KotH> av500: milka isn't equivalent payment to a daughter!
Nov 22 13:59:14 <honestly> prolly should
Nov 22 13:59:18 <thews> IamTrying: you can use two serial pins from arduino to BBB with logic converters to communicate
Nov 22 13:59:23 * KotH demands to get either läderach or the daughter
Nov 22 13:59:23 <av500> i'll add RitterSpocht
Nov 22 13:59:40 <thews> IamTrying: you can also control relays with BB
Nov 22 13:59:44 <IamTrying> thews, WOW
Nov 22 14:00:20 <IamTrying> thews, How does the 42x2 pins works? How do i know which one is 5V pin, which one is GND and which one is Pin1, 2 etc like Arduino ?
Nov 22 14:00:27 <av500> you read the doc
Nov 22 14:00:30 <thews> sainsmart makes cheap relay boards, I believe they have some 3.3v boards, but they aren't higher amp, they have 10 amp relays that work off of 5v, but can take 3.3v on signaling
Nov 22 14:00:33 <av500> or the net
Nov 22 14:00:42 <av500> same as you did for arduino
Nov 22 14:00:56 <av500> outrageous, I know
Nov 22 14:01:11 <thews> IamTrying: http://lmgtfy.com/?q=beagleboard+black+pinout
Nov 22 14:01:37 <av500>  http://lmgtfy.com/?q=beaglebone+black+SRM
Nov 22 14:02:13 <thews> :)
Nov 22 14:02:30 <thews> my brain is fuzzy this AM
Nov 22 14:03:04 <KotH> thews: well... a 10A relay is easy to switch with even 3V3... but how much current do you have to provide?
Nov 22 14:03:04 <IamTrying> WOW - great, thank you so much av500 , thews , this is my first week playing with beagle
Nov 22 14:03:51 <IamTrying> KotH, my relay is for a lights (like stadium lights too much consume) will a 3V relay enough?
Nov 22 14:03:54 <av500> http://www.youtube.com/watch?v=vvoGic3eig0
Nov 22 14:03:59 <thews> KotH: most cheap 10A 250V relays can't be switched off of 3.3v
Nov 22 14:04:10 <KotH> IamTrying: the voltage is not the problem
Nov 22 14:04:25 <KotH> IamTrying: if you try to switch a relay directly from a bbb pin, you will definitly fry your beagle
Nov 22 14:04:30 <KotH> IamTrying: electronics 101
Nov 22 14:04:57 <KotH> thews: i wouldnt use a relay to switch 240V anyways ;)
Nov 22 14:05:05 <IamTrying> KotH, with Arduino the stadium lights were not working relay shows working but light remains forever on
Nov 22 14:05:10 <av500> depends on the relay
Nov 22 14:05:13 <IamTrying> KotH, so i am switching to beagle for this reason
Nov 22 14:05:30 <thews> but sainsmart makes relay boards that have logic converters already built in that can take 3.3v with minimal latching current
Nov 22 14:05:42 * thews uses them for greenhouse automation
Nov 22 14:05:45 <av500> http://www.amazon.de/dp/B007KM065U/?smid=A2RQ26FRS9UTKN
Nov 22 14:05:54 <IamTrying> I have relay which is in 3V pin and GND and pin 1, the stadium light is always on, even i do relay switch off or on av500 , KotH
Nov 22 14:06:07 <thews> http://www.sainsmart.com/8-channel-dc-5v-relay-module-for-arduino-pic-arm-dsp-avr-msp430-ttl-logic.html
Nov 22 14:06:11 <KotH> IamTrying: it's probably not arduinos fault if you havent done the electronics right
Nov 22 14:06:19 <honestly> KotH: what would you use? huge transistors?
Nov 22 14:06:23 <av500> sorry, my crystal ball is broken
Nov 22 14:06:40 <KotH> honestly: either opto-FETs or electronic relays
Nov 22 14:06:54 <honestly> right
Nov 22 14:06:55 <IamTrying> thews, i am using those already for Stadium light and they do not work
Nov 22 14:07:06 <KotH> honestly: the later have the advantage of switching at the zero crossing, which reduces EMI
Nov 22 14:07:11 <IamTrying> KotH, please advise why the lights are on even arduino was power off and relay is switch off?
Nov 22 14:07:20 <av500> IamTrying: well of course
Nov 22 14:07:22 <honestly> lol
Nov 22 14:07:30 <av500> you cannot run stadium lights from tiny relay
Nov 22 14:07:34 <thews> IamTrying: I don't know what you mean by stadium light,  they work fine for HID MH HPS lights, which are often used for stadiums
Nov 22 14:07:39 <av500> you most likely fry your contacts
Nov 22 14:07:41 <av500> so they stick
Nov 22 14:07:53 <av500> get a proper relay
Nov 22 14:07:58 <IamTrying> av500, EXACTLY guru it was my wild junior guess. How can resolve it plz??
Nov 22 14:07:59 <thews> av500: HPS stadium lights work fine 250v with about 5 amps
Nov 22 14:08:08 <av500> if needed do 3.3V -> 220 and then use 220 to switch a big one
Nov 22 14:08:19 <av500> IamTrying: wrong channel
Nov 22 14:08:21 <av500> :)
Nov 22 14:08:27 <KotH> IamTrying: most probable reason: you welded the relay contacts together, because you used a too small relay for the load
Nov 22 14:08:28 <av500> but again
Nov 22 14:08:30 <av500> google it
Nov 22 14:08:35 <av500> google it
Nov 22 14:08:36 <av500> google it
Nov 22 14:08:54 <KotH> IamTrying: also be aware that releasing a relay needs force too
Nov 22 14:09:14 <av500> and listen to: http://www.youtube.com/watch?v=vvoGic3eig0
Nov 22 14:09:16 <thews> especially if you are using the wrong side of the relay's terminals
Nov 22 14:10:14 <KotH> thews: "15-20mA Driver Current"
Nov 22 14:10:27 <KotH> thews: that's more than your average arduino can supply per output pin
Nov 22 14:10:40 <KotH> thews: too much by a factor of 15-20
Nov 22 14:11:05 <thews> KotH: that board transistors / logic converters,  I've used them plenty
Nov 22 14:11:09 <thews> has*
Nov 22 14:11:15 <KotH> ah..
Nov 22 14:11:16 <KotH> ok
Nov 22 14:11:22 <KotH> the description is a bit weird, then
Nov 22 14:11:26 <thews> it's really off
Nov 22 14:11:36 <av500> http://www.amazon.de/dp/B007KM065U/?smid=A2RQ26FRS9UTKN
Nov 22 14:11:39 <thews> if you notice it says for RPI, which doesn't have nearly that kind of current on the pins
Nov 22 14:11:43 <av500> something like that
Nov 22 14:12:03 <av500> 3-phase is overkill of course
Nov 22 14:12:07 <av500> but there are 1-phase too
Nov 22 14:12:10 <KotH> av500: how many people here know what that is?
Nov 22 14:12:13 <thews> yeah
Nov 22 14:12:18 <thews> unnecessary
Nov 22 14:12:21 <IamTrying> OH ic av500 , those are really electrical relays i see them in my home made by professionals
Nov 22 14:12:32 <IamTrying> av500, you are 100% correct that is causing my problem
Nov 22 14:12:46 <IamTrying> av500, those small relay cant act like those relay u  linked
Nov 22 14:12:55 <KotH> lol
Nov 22 14:12:56 <IamTrying> OK - great thank you so much av500 its much clear now
Nov 22 14:12:57 <KotH> no it cannot
Nov 22 14:13:04 <KotH> small relay -> small load
Nov 22 14:13:04 <av500> http://en.wikipedia.org/wiki/Contactor
Nov 22 14:13:09 <KotH> large relay -> large load
Nov 22 14:13:19 <KotH> anyways... tea time
Nov 22 14:13:20 <av500> huge relay -> huge load
Nov 22 14:13:47 <IamTrying> Man you guys are genius thank you so much i was so deadly confused its much clear now, av500 , KotH , thews
Nov 22 14:13:48 <KotH> av500: i've once worked on a 600kV, 500A "relay" :)
Nov 22 14:14:05 <KotH> IamTrying: we are not genius, we just know more than you do ;)
Nov 22 14:14:15 <IamTrying> +1
Nov 22 14:14:45 <thews> av500: https://www.youtube.com/watch?v=XtqbfGJEOr8  my first attempt at an arduino web controlled relay box
Nov 22 14:14:51 <KotH> IamTrying: http://www.amazon.de/Halbleiter-Schaltungstechnik-Ulrich-Tietze/dp/3642310257/
Nov 22 14:14:55 <KotH> IamTrying: get this book!
Nov 22 14:15:05 <av500> :)
Nov 22 14:15:28 <KotH> av500: you should have been at my talk ;)
Nov 22 14:17:13 <av500> KotH: http://ecx.images-amazon.com/images/I/91v3-QLgCdL._SL1500_.jpg
Nov 22 14:17:48 <thews> is that the german bible?
Nov 22 14:17:54 * thews kids
Nov 22 14:19:56 <KotH> av500: if are throwing yours away, i'll take it ;)
Nov 22 14:20:13 <av500> I have 1-4
Nov 22 14:20:16 <av500> miss 5
Nov 22 14:20:44 <KotH> doesnt matter, i'll take them anyways
Nov 22 14:21:30 <av500> thews: like your 'lectric box
Nov 22 14:21:40 <av500> like that its not in my house
Nov 22 14:21:57 <thews> av500: here's some of the stuff I control http://www.youtube.com/watch?v=h9X91L9okyM http://www.youtube.com/watch?v=nwR6sDBNOTY
Nov 22 14:22:50 <av500> thews: the weed you grow any good?
Nov 22 14:23:00 <thews> don't grow any
Nov 22 14:23:05 <thews> other stuff grows like weeds though :)
Nov 22 14:23:50 <KotH> ah.. good.. i've found a vicitim!
Nov 22 14:24:04 <KotH> thews: are there any good books to learn about hydroponics?
Nov 22 14:24:25 <thews> KotH: yeah, if you have amazon prime there is a good one you can borrow for free
Nov 22 14:24:29 * thews digs it out
Nov 22 14:24:53 <KotH> there is no prime in switzerland
Nov 22 14:25:07 <thews> http://www.amazon.com/How-To-Hydroponics-Fourth-Edition-Roberto/dp/0967202612/ref=sr_1_1?ie=UTF8&qid=1385130292&sr=8-1&keywords=how+to+hydroponics
Nov 22 14:25:08 <thews> ahh
Nov 22 14:27:50 <janne> I think book lending is also US prime only
Nov 22 14:28:35 <KotH> i think, i can lend/borrow books without prime and outside US ;)
Nov 22 14:34:54 <thews> :)
Nov 22 14:39:19 <janne> KotH: I've heard there are buildings hosting shelfes filled with books which you can lend ;)
Nov 22 14:40:48 <thews> scholar.google.com is the best if you want really good information, but a book helps you piece it all together to start with
Nov 22 14:41:05 <thews> once you have the basic understanding, then you can expand into the science parts
Nov 22 14:41:52 <thews> lots of research into bioavailability, enzymes, aquaculture, organics
Nov 22 14:43:46 <thews> it's a good hobby though
Nov 22 14:44:13 <thews> not very expensive, and it's a field that is critical to survival and thriving, but most people don't care about at all
Nov 22 14:44:37 <KotH> most people dont care about anything but their next bigmac and whom to sleep with next
Nov 22 14:46:52 <thews> because a large group of people clandestinely grow pot in america, sometimes I can get some really good deals buying stuff in bulk
Nov 22 14:47:19 <thews> some parts that cost $12 normally each, I can get for a dollar or two
Nov 22 14:47:52 <thews> if you are growing a lot of the same type of crop, you can grow a LOT of it for not much extra cost, and no extra maintenance
Nov 22 14:48:38 * KotH doesnt grow pot
Nov 22 14:48:44 <KotH> and i dont inted to
Nov 22 14:48:53 <KotH> actually, i dont even have the space for growing anything :-(
Nov 22 14:49:06 <av500> grow a beard
Nov 22 14:49:56 <thews> you don't need more than a closet sized area to grow plants
Nov 22 14:50:06 <thews> you can actually make it multi level and grow quite a bit
Nov 22 14:50:23 <thews> one person I helped out getting started grew lettuce beside their monitor on their desk getting started
Nov 22 14:50:39 <thews> then they upgraded to make a rack shelf system above their desk and grow maybe 50 plants indoors
Nov 22 15:05:50 <bbm> hii
Nov 22 15:06:25 <bbm> can any give me the link for beagle bone compiler toolchain please
Nov 22 15:06:42 <av500> hmm
Nov 22 15:06:42 <_vicash_> Hi all. Does the BBB have OpenGL native driver support in the default Angstrom image ? I see that my OpenGL application uses nearly 95% CPU all the time which makes it difficult to run other things
Nov 22 15:06:48 <av500> no
Nov 22 15:06:54 <av500> no openGL yet
Nov 22 15:06:56 <av500> eta unknown
Nov 22 15:06:59 <av500> probably never
Nov 22 15:07:06 <_vicash_> sucks. why do they call it open hardware then
Nov 22 15:07:27 <SpeedEvil> Because it's way more open than most.
Nov 22 15:07:33 <_vicash_> and they advertise the SGX processor like the second coming of christ
Nov 22 15:07:43 <av500> where?
Nov 22 15:07:45 <_vicash_> thanks !
Nov 22 15:07:49 <SpeedEvil> Unfortunately, in mobile space, TI is about as good as it gets.
Nov 22 15:07:56 <SpeedEvil> And they're getting out.
Nov 22 15:08:07 <SpeedEvil> (from a documentation and openness perspective)
Nov 22 15:08:37 <_vicash_> that is too bad.
Nov 22 15:08:46 <_vicash_> the BBB is really nice hardware
Nov 22 15:09:11 <bbm> can any give me the link for beagle bone compiler toolchain please
Nov 22 15:09:27 <thews> av500: is there an older angstrom release with opengl ?
Nov 22 15:09:37 <thews> or opengles or whatever that one is
Nov 22 15:10:00 <av500> old releases for BBW had opengl
Nov 22 15:10:06 <av500> based on 2.6.32 or sp
Nov 22 15:10:06 <thews> ahh
Nov 22 15:10:14 <av500> with some chnages they can be made to run on BBB
Nov 22 15:11:00 <_vicash_> av500: Here you go. In the first paragraph it says that BBB has OpenGL, http://www.h-online.com/open/news/item/BeagleBone-Black-aims-to-compete-with-Raspberry-Pi-1847904.html
Nov 22 15:11:07 <jkridner> bbm: source or binary?
Nov 22 15:11:16 * _vicash_ finding other press releases
Nov 22 15:11:40 <jkridner> av500: 3.2.x had OpenGL support
Nov 22 15:11:47 <av500> jkridner: good
Nov 22 15:11:56 <jkridner> TI just released SGX code for 3.12, but it needs integration.
Nov 22 15:11:58 <av500> give the man a link to download
Nov 22 15:12:14 <av500> jkridner: yes, it needs integration since ever :)
Nov 22 15:12:52 <_vicash_> jkridner: when you say integration you mean the 3.8 angstrom linux kernel has to be upgraded to 3.12 ?
Nov 22 15:12:59 <jkridner> http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_UserGuide
Nov 22 15:13:28 <thews> jkridner: I saw that release and I'm really hoping it gets tied in
Nov 22 15:13:33 * thews would be very thankful
Nov 22 15:15:25 <_vicash_> jkridner: so basically if I run Android JB on the BBB I can get OpenGL acceleration ?
Nov 22 15:17:03 <KotH> jkridner: what's missing for full graphics support on the bbb?
Nov 22 15:17:13 <KotH> jkridner: just SGX in mainline?
Nov 22 15:17:18 <jkridner> yup.
Nov 22 15:17:29 <KotH> what holding that back?
Nov 22 15:17:38 * KotH remembers having seen patches a year ago
Nov 22 15:17:44 <jkridner> I'm not sure.
Nov 22 15:17:59 <KotH> please dont tell me it's ACPI?
Nov 22 15:18:07 <thews> DRM kernel changes
Nov 22 15:18:36 <thews> I don't think ARM has ACPI
Nov 22 15:18:52 <SpeedEvil> ACPI is x86
Nov 22 15:19:05 <jkridner> _vicash_: you just need a kernel with SGX integrated and the associated userspace libraries. The Android release uses the 3.2 kernel.
Nov 22 15:20:41 <thews> jkridner: do you think it'd be worth crowdsourcing some funding for getting that issue resolved?
Nov 22 15:21:08 <thews> It's worth 30 bucks to me
Nov 22 15:21:17 <jkridner> don't think it could hurt.
Nov 22 15:21:27 <jkridner> would need to figure out who to pay.
Nov 22 15:21:46 <jkridner> I have some other work I'd like to pay for as well.
Nov 22 15:21:50 <thews> I'd figure someone over at TI on the SDK team
Nov 22 15:22:00 <jkridner> they are already getting paid.
Nov 22 15:22:08 <jkridner> crowdfunding wouldn't help there.
Nov 22 15:22:13 <thews> maybe TI would take notice
Nov 22 15:22:19 <thews> or accept it as a customization fee
Nov 22 15:22:42 * jkridner is kinda reluctant to hand over money without a commitment.
Nov 22 15:22:48 <thews> definitely
Nov 22 15:23:21 <jkridner> I could try asking if a certain amount of money would generate a commitment, but I'm not sure how that would look for TI.
Nov 22 15:23:37 <jkridner> I mean, are they supposed to do this work anyway or not?
Nov 22 15:23:42 <jkridner> they == we
Nov 22 15:23:53 <thews> I work for a software company and we accept $ for customizations that aren't part of our normal business
Nov 22 15:24:14 <jkridner> k.  I like attaching the word "customizations" onto it.
Nov 22 15:24:38 <jkridner> guess I could try to get a quote.
Nov 22 15:24:45 <thews> that's the only way I see it fitting into a model and not calling it a bribe
Nov 22 15:24:56 <thews> or extortion :)
Nov 22 15:25:22 <jkridner> you want to run the campaign and I can get a quote?
Nov 22 15:25:32 <dwery> wasn't there a web site to post bounties for open source features?
Nov 22 15:25:50 <thews> I can definitely check out some of the crowdsource options and make some accounts to publicize it
Nov 22 15:26:12 <thews> indiegogo maybe + twitter and google plus campaign
Nov 22 15:26:30 <Crofton|work> we should place some bounties on TI managers
Nov 22 15:26:45 <dwery> I;m not that interested in OpenGL but I'm certainly in with a few bucks for the sake of supporting the BBB
Nov 22 15:26:56 <KotH> SpeedEvil: you are behind the times!
Nov 22 15:27:27 <SpeedEvil> KotH: err?
Nov 22 15:27:36 * SpeedEvil fails context.
Nov 22 15:27:40 * SpeedEvil needs more coffee.
Nov 22 15:27:44 <SpeedEvil> Or less coffee.
Nov 22 15:28:04 <KotH> SpeedEvil: http://lwn.net/Articles/574439/
Nov 22 15:28:27 <SpeedEvil> I'm not a subscriber alas.
Nov 22 15:29:04 <KotH> SpeedEvil: it's a damn huge thread on linux-arm/devictree
Nov 22 15:29:16 <KotH> SpeedEvil: man up and get an lwn subscription ;)
Nov 22 15:29:20 <jkridner> dwery: https://www.bountysource.com/ ?
Nov 22 15:29:35 <SpeedEvil> KotH: At the moment this room is at 7C because I can't afford heating.
Nov 22 15:29:35 <thews> looks good
Nov 22 15:29:42 <KotH> SpeedEvil: ouch
Nov 22 15:29:47 <KotH> SpeedEvil: what did you do wrong?
Nov 22 15:29:51 <thews> it's 20F here right now
Nov 22 15:29:52 <thews> :S
Nov 22 15:29:59 <SpeedEvil> KotH: Catch a virus at age 12.
Nov 22 15:30:03 <KotH> :-(
Nov 22 15:30:26 <thews> going outside in a bit is going to suck
Nov 22 15:30:29 <SpeedEvil> -> Chronic Fatigue Syndrome.
Nov 22 15:30:58 <KotH> SpeedEvil: what damn country are you living in that you dont get enough money for proper heating?
Nov 22 15:31:03 <thews> SpeedEvil: you on any amphetamines ?
Nov 22 15:31:06 <dwery> jkridner: yes, I think it was that one
Nov 22 15:31:08 <SpeedEvil> The UK.
Nov 22 15:31:20 <SpeedEvil> There are no specific benefits that cover heating.
Nov 22 15:31:28 <KotH> SpeedEvil: damn.. another victim of that third world country :-(
Nov 22 15:32:10 <SpeedEvil> I do get $200/year, to help with heating - but due to the poor insulation if I was to actually heat properly to 20C say that would be used up in several weeks.
Nov 22 15:32:41 * KotH knows how english houses are insulated...
Nov 22 15:33:58 <thews> even here in mega capitalist america the poor get heating
Nov 22 15:34:08 <thews> it comes from donations to the electric company though
Nov 22 15:34:47 <KotH> thews: afaik, the uk is only slightly better than the us, when it comes to social welfare
Nov 22 15:39:57 <_vicash_> SpeedEvil: you can heat yourself by running a 100% CPU using application on the BBB ;)
Nov 22 15:40:28 <SpeedEvil> KotH: It's complex.
Nov 22 15:41:00 <SpeedEvil> KotH: Suffice it to say I've spent the past couple of years in much of my limited free time reading and understanding benifit rules, and caselaw, and primary legislation.
Nov 22 15:41:12 <SpeedEvil> Rahter than doing actual productive stuff.
Nov 22 15:41:19 <_vicash_> jkridner: i like the idea of the crowdsourcing.. if there can be an estimate on the amount of effort needed that would be useful
Nov 22 15:41:21 <SpeedEvil> (free time = time in which I'm mentally competant)
Nov 22 15:41:23 <KotH> SpeedEvil: i know how that is. even living in .ch i had my fair share of that
Nov 22 15:41:27 <jkridner> dwery: hmmm... how do I figure out a price for it?
Nov 22 15:41:49 <jkridner> I could try to get a quote from TI to do it, but I don't know that TI could respond on bountysource.
Nov 22 15:41:57 <dwery> jkridner: that's the hardest part. first think to figure, is who can do it. TI only? any programmer?
Nov 22 15:42:06 <dwery> s/think/thing/
Nov 22 15:42:43 <jkridner> argh, everytime I want to share something that happens here, I see BeagleBot is down. :(
Nov 22 15:42:57 <dwery> jkridner: don't tell them it's crowdsourced
Nov 22 15:43:28 <thews> SpeedEvil: I've read that the treatment for that problem is the same as it is for narcolepsy,  mostly amphetamine based stuff
Nov 22 15:43:31 <elyezer> hi all. On beaglebone black I saw that /etc/network/interfaces comes with a configuration for usb network device. When configuring the board must I need to leave the usb configuration untouched?
Nov 22 15:43:55 <SpeedEvil> thews: There is no effective treatment.
Nov 22 15:43:57 <SpeedEvil> At all.
Nov 22 15:44:01 <thews> jkridner: if you can get a quote, we can probably make it happen one way or another
Nov 22 15:44:14 <thews> SpeedEvil: have you tried the amphetamine based stuff?
Nov 22 15:44:17 <SpeedEvil> No treatment has been found to be clinically viable in a significant proportion of cases.
Nov 22 15:44:19 <jkridner> k, gonna start that effort now.
Nov 22 15:44:55 <thews> jkridner: In the last week I've been idling here I've seen that issue come up a lot, and I'm sure it'll get worse once tre is shipped
Nov 22 15:44:57 <SpeedEvil> Stimulants don't help - for many of the same reasons they don't really help people to stay up 96 hours.
Nov 22 15:45:16 <thews> SpeedEvil: amphetamines are notorious for helping people stay up 96 hours
Nov 22 15:45:29 <thews> SpeedEvil: but staying up 96 hours has it's own side effects
Nov 22 15:45:53 <SpeedEvil> Much of the time I'm in a very similar state.
Nov 22 15:45:55 <jkridner> Integration into Angstrom images and Debian images, right? What else?
Nov 22 15:46:00 <SpeedEvil> After, for example, doing the washing up.
Nov 22 15:46:07 <SpeedEvil> Anyway - off topic.
Nov 22 15:46:13 <thews> jkridner: that's all that matters to the majority I think
Nov 22 15:46:46 <_vicash_> jkridner: if OpenGL libraries can use the native SGX driver to run that will be great. i think the kernel driver for SGX should be handling that seamlessly
Nov 22 15:46:58 <KotH> SpeedEvil: you're in #beagle
Nov 22 15:47:06 <KotH> SpeedEvil: being on-topic is off-topic here
Nov 22 15:47:33 <jkridner> hmmm... http://logs.nslu2-linux.org/livelogs/beagle/beagle.20131122.txt log seems incomplete.
Nov 22 15:47:50 <thews> for smaller channels staying fully on topic stifles ideas
Nov 22 15:48:14 <SpeedEvil> To restate it - I'm not especially interested in conversing about this in depth. If it was found that cutting my legs off would cure me, I'd have them off tomorrow. I've been doing research into actual clinical outcomes and there is nothing promising.
Nov 22 15:48:15 * jkridner sees nslu2-log
Nov 22 15:48:23 <jkridner> guess it takes a while to refresh?
Nov 22 15:48:32 <thews> must
Nov 22 15:51:48 <thews> SpeedEvil: I sent you a pm
Nov 22 15:57:29 <_vicash_> jkridner: maybe you could contact Robert Nelson to get an idea of how much effort it would take to port the SGX from Android JB to Angstrom.
Nov 22 15:58:50 <thews> if the android jb is on 3.2 as someone said earlier it would be completely different
Nov 22 15:59:04 <thews> but a few TI documents showed 3.8 and 3.12
Nov 22 15:59:12 <thews> one specifically said they were testing 3.8
Nov 22 16:00:53 <thurgood>  what port of sgx? they're running a kernel that is still supported
Nov 22 16:00:57 <dury> hi there channel :-) I've just ordered yesterday beagleboard black :-)
Nov 22 16:01:25 <thurgood> namely 3.2
Nov 22 16:01:51 <thurgood> they've just adapted the kernel to run with the bbb
Nov 22 16:01:58 <dury> one unit 56 € I guess
Nov 22 16:02:24 <dury> what other accessories can I add to it?
Nov 22 16:02:35 <_vicash_> thurgood: if you try to build Angstrom from scratch there is only the option to run linux 3.7 or 3.8 .. if 3.2 works shouldn't that be an option for those who need SGX support
Nov 22 16:03:13 <dury> a touchscreen display is it possible?
Nov 22 16:03:20 <thurgood> 3.2 default does not support the bbb
Nov 22 16:03:22 <thews> dury: since the BBB has several interfaces there are almost unlimited possibilities
Nov 22 16:03:48 <_vicash_> dury: yes there are many possibilities check elinux.org for more details on what you can do with LCDs and which LCDs to pick
Nov 22 16:03:55 <thews> dury: there are touchscreen capes, also you can use hdmi + another interface
Nov 22 16:05:35 <dury> are there any video on youtube or whatever to see the possibilities?
Nov 22 16:06:19 <_vicash_> dury: Yes please read this guy's blog . he does a lot of work on the BBB and has great tutorial videos http://derekmolloy.ie/beaglebone/
Nov 22 16:07:22 <dwery> dury: check the cape list
Nov 22 16:07:43 <jkridner> _vicash_: he's already looking at it
Nov 22 16:08:39 <_vicash_> jkridner: that's cool
Nov 22 16:08:46 <dury> dwery cape list... sorry to ask ... but where is it
Nov 22 16:09:07 <dwery> dury: http://elinux.org/Beagleboard:BeagleBone_Capes
Nov 22 16:12:18 <ubitux> any arm64 beagle boards available?
Nov 22 16:13:11 <thews> ubitux: I don't think any arm64 popular devboards will be around for a while
Nov 22 16:13:40 <ubitux> that's unfortunate
Nov 22 16:13:41 <dury> dwery: so I can use BBB as personal computer as well
Nov 22 16:14:01 <dwery> well..it depends on what you want to do with it
Nov 22 16:14:44 <thews> ubitux: http://microcontrollershop.com/product_info.php?products_id=4129  pretty cheap, but the popular arm64 stuff is just getting started
Nov 22 16:14:46 <dury> what are the possibilities then?
Nov 22 16:15:38 <dwery> dury: embedded, home automation, micro server, etc
Nov 22 16:16:20 <thews> dury: you might be interested in ninja blocks, which use BBB
Nov 22 16:16:37 <thews> http://ninjablocks.com/collections/ninja-blocks/products/ninja-shield-for-beaglebone-black
Nov 22 16:17:23 <_vicash_> dury: you can run Debian on the BBB and use it as a Linux PC to do things except run 3D software. it maybe be slightly slower than an x86 PC depending on what you're trying to do but otherwise works fine. I build display software that runs on the BBB connected to a TV via HDMI
Nov 22 16:17:50 <thews> or watch videos in many formats
Nov 22 16:18:45 <thews> arm7 devices are considerably slower than atom x86 for almost everything unless there are onboard chips that handle specific tasks
Nov 22 16:19:18 <thews> but they're much cheaper and can accomplish a wide range of tasks very well
Nov 22 16:22:59 <bbm> hii
Nov 22 16:23:23 <bbm> can anyone please see why this is coming

Nov 22 16:23:54 <dury> can I connect a sata HD with BBB?
Nov 22 16:24:12 <bbm> i am cmpiling the u boot
Nov 22 16:25:11 <_vicash_> bbm: u-boot has a separate channel on #u-boot . you will get more help there
Nov 22 16:25:30 <bbm> thanks
Nov 22 16:25:30 <_vicash_> dury: via USB you can connect anything to the BBB
Nov 22 16:28:23 <dury> can it build a dronner?
Nov 22 16:31:08 <dury> a drone I mean sorry
Nov 22 16:32:46 <ubitux> dury: yes; as said, everything is through usb, so you have to plug this and you're done: https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcQyULr0l0OVhR-UgjrPOuwmUruqV9Ca00CKloVau1ZsuVvoaqmD
Nov 22 16:34:21 <dury> ubitux all right
Nov 22 16:34:24 <Nedlinpopo> have any of you guys had awesome hard lockups with a *lot* of USB traffic?
Nov 22 16:34:51 <thews> Nedlinpopo: I've had strange lockups, but I don't know what to account it to
Nov 22 16:35:03 <ubitux> (dury: that was a joke, right?)
Nov 22 16:35:21 <Nedlinpopo> thews: do you have any USB devices attached which do big bulk transfers?
Nov 22 16:35:28 <dury> no worries
Nov 22 16:35:56 <Nedlinpopo> i.e. cameras, network dongles, GSM modems, some soundcards
Nov 22 16:36:15 <thews> Nedlinpopo: I've maxed out usb on data transfer, and I've had a few lockups early on,  I'm not sure if it was because of wifi drivers that also gave me problems, or usb drive or what
Nov 22 16:36:30 <Nedlinpopo> bummer
Nov 22 16:36:33 <thews> Nedlinpopo: I also have video and sound through hdmi, but usually don't run X
Nov 22 16:36:45 <thews> Nedlinpopo: everything is much more stable now
Nov 22 16:36:55 <thews> Nedlinpopo: the major thing was compiling my own wifi driver
Nov 22 16:36:55 <Nedlinpopo> what kernel are you running?
Nov 22 16:37:10 <Nedlinpopo> (with which patches)
Nov 22 16:37:12 <thews> 3.8.13-bone20 or 30 I think
Nov 22 16:37:14 <thews> not at home right now
Nov 22 16:37:55 <Nedlinpopo> where did you get the source?
Nov 22 16:37:59 <thews> Nedlinpopo: https://github.com/justinledwards/beaglebone-debian-scripts/blob/master/wireless-fix.sh
Nov 22 16:38:08 <Nedlinpopo> great
Nov 22 16:38:10 <Nedlinpopo> thanks
Nov 22 16:38:10 <thews> that's some of the stuff I did for the wireless drivers
Nov 22 16:39:21 <Nedlinpopo> My work had had some serious sucking with USB, and on the previous project there wasn't time to debug it, but now i'm getting back to it.  Hopefully I'll fix it for good.  I've heard rumors of EMI/noise issues as well there.
Nov 22 16:39:39 <thews> I haven't had those problems with the BBB
Nov 22 16:39:58 <thews> I've majority had those problems when working with long traces / wires with other ICs
Nov 22 16:40:04 <thews> majorly
Nov 22 16:40:17 <Nedlinpopo> heh, you know the sayuing:
Nov 22 16:40:47 <Nedlinpopo> "there are 2 kinds of electrical engineers, those with Signal integrity problems, and those who will have them"
Nov 22 16:40:58 <thews> definitely
Nov 22 16:41:21 <thews> I toss capacitors on most things now and try to keep the busses as short as possible
Nov 22 16:41:50 <Nedlinpopo>  my rule of thumb is one cap per power pin
Nov 22 16:41:54 <thews> not worth the complications that happen otherwise
Nov 22 16:42:18 <thews> I put a cap on every IC that takes / pushes signaling if they're not really close together
Nov 22 16:42:28 <thews> and cap the power on input and output
Nov 22 16:42:52 <thews> if there is voltage regulation / conversion
Nov 22 16:43:26 <Nedlinpopo> i'm always leery ov caps on signal wires, but otherwise sound advice
Nov 22 16:43:49 <Nedlinpopo> also, apparently i can't type to save my life today
Nov 22 16:43:55 <thews> for SPI you can cap the latch I think, that's about all for signalling
Nov 22 16:46:16 <dury> all right guys... really appreciate your suggestions. I'll be back in other time cheeerss :-)
Nov 22 16:46:22 <thews> yeah capacitor on the latch pin for SPI doesn't hurt,  stops flickering
Nov 22 16:47:34 <Nedlinpopo> sounds plausible.  some chips rely on set-up time from that, but probably fine mostly
Nov 22 16:48:52 <bpetersen> Anyone know good chats about electrical design? For example, I have a power mosfet and I want to test the output current using a load resistor. How do I determine a good power rating for the load resistor
Nov 22 16:51:55 <Nedlinpopo> just do ohms law
Nov 22 16:51:58 <Nedlinpopo> and watts law
Nov 22 16:52:05 <Nedlinpopo> I*I*R
Nov 22 16:52:18 <Nedlinpopo> and add 20% for safety
Nov 22 16:54:45 <corrosion> is Gerald from the google group here?
Nov 22 17:05:32 <Nedlinpopo> okay, off to the races. thanks for the info
Nov 22 17:11:08 <paolo_> hi
Nov 22 17:11:45 <paolo_> the BeagleBone Black boot up when i insert a power supplay?
Nov 22 17:12:22 <paolo_> or i can push power botton?
Nov 22 17:15:27 <paolo_> please answere
Nov 22 17:15:43 <paolo_>  the BeagleBone Black boot up when i insert a power supplay? or i can push power botton?
Nov 22 17:15:49 <carpman> paolo_: it will boot as soon as you connect power.

Nov 22 18:46:58 <_av500_> what board?
Nov 22 18:47:10 <_av500_> on BBB, you need to hold the boot button while powerin up
Nov 22 18:47:29 <_av500_> also, get a serial cable
Nov 22 18:47:54 <mn_> im using bbb.. im doing the same..ive everything with me..
Nov 22 18:48:06 <mn_> i'll paste the logs here..
Nov 22 18:48:10 <mn_> plz wait..
Nov 22 18:48:49 <thurgood> use pastebin please

Nov 22 18:49:42 <_av500_> pastebin please
Nov 22 18:50:04 <thurgood> invalid partition 2... where is your rootfs?
Nov 22 18:50:21 <mn_> i dont want to boot linux
Nov 22 18:50:31 <mn_> i want to boot only uboot
Nov 22 18:50:43 <mn_> which i have compiled
Nov 22 18:51:31 <mn_> i want the 1st bootloader to detect sd card and boot MLO and uboot.img from ext sd card
Nov 22 18:52:16 <_av500_> pastebin please
Nov 22 18:52:46 <vinifr> you already did get :)
Nov 22 18:52:59 <mn_> what is pastebin
Nov 22 18:53:05 <mn_> i didnt get you
Nov 22 18:54:04 <vinifr> http://pastebin.com/
Nov 22 18:55:43 <mn_> http://pastebin.com/gvJAchWF
Nov 22 18:56:14 <mn_> could you check there please
Nov 22 18:56:54 <thurgood> that's uboot trying to hand off to the rootfs
Nov 22 18:57:05 <mn_> yeah...
Nov 22 18:57:19 <mn_> but it is not from my sd card
Nov 22 18:57:31 <mn_> it is executing from emmc card
Nov 22 18:57:36 <thurgood> probably from the emmc
Nov 22 18:58:08 <mn_> yes but.. I am trying to boot u boot from my sd card
Nov 22 18:58:19 <mn_> where I have some changes to u boot
Nov 22 18:58:21 <thurgood> you should be able to hold the boot button while applying power
Nov 22 18:58:49 <thurgood> to change the boot order
Nov 22 18:58:59 <mn_> yes.... i am holding it for  a long time but there is not response
Nov 22 18:59:12 <mn_> no led is blinking
Nov 22 18:59:39 <mn_> as long as  i press the boot button
Nov 22 19:00:39 <vinifr> mn_, you booted from SD card, not emmc. "MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1"
Nov 22 19:01:34 <mn_> I didnot get you vinifr
Nov 22 19:01:40 <mn_> how to confirm that
Nov 22 19:04:19 <vinifr> "MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1" and "micro SD card found" and "mmc0 is current device"
Nov 22 19:04:48 <vinifr> eMMC is a nand memory
Nov 22 19:05:13 <vinifr> "NAND:  No NAND device found!!!"
Nov 22 19:05:35 <mn_> the uboot from emmc is detecting the sd card
Nov 22 19:05:38 <sam___> can we use BF-810 (GND,Rx,TX pins) as serial debug wire for Beaglebone Black ?
Nov 22 19:05:52 <mn_> I hope this is happening
Nov 22 19:06:13 <thurgood> check the date of uboot...
Nov 22 19:08:12 <mn_> it is june 19 2013
Nov 22 19:08:17 <mn_> not my build date
Nov 22 19:08:24 <mn_> I have built just now
Nov 22 19:10:59 <vinifr> If you remove the sd, is the log the same?
Nov 22 19:11:07 <mn_> yes
Nov 22 19:11:12 <mn_> the same log
Nov 22 19:11:20 <vinifr> :o
Nov 22 19:11:43 <mn_> expect sd card detection
Nov 22 19:11:44 <sam___> can we use Bafo BF-810 (GND,Rx,TX pins) as serial debug wire for Beaglebone Black ?
Nov 22 19:11:45 <mn_> :)
Nov 22 19:12:17 <mn_> @sam_s you can use
Nov 22 19:13:39 <sam___> But can this damage 3.3v pins ?
Nov 22 19:13:56 <vinifr> mn_, how do you write uboot-image for SD?
Nov 22 19:15:35 <mn_> first im formating the sd card in FAT32. then im copying the MLO and u-boot Image files inti it..
Nov 22 19:15:58 <thurgood> also did you set the partition to bootable?
Nov 22 19:16:23 <mn_> ]and connecting to the board and holding the boot button gave the power.
Nov 22 19:16:31 <vinifr> do you use 'cp' or 'dd'?
Nov 22 19:16:39 <mn_> cp
Nov 22 19:16:55 <mn_> im doing it in windows..
Nov 22 19:17:32 <vinifr> so really does not work :)
Nov 22 19:18:14 <mn_> what am i supposed to do now.. plz help me out..
Nov 22 19:18:19 <thurgood> you can do the boot partition in windows fine, although in general I'd suggest having a linux box for dev work with the bbb
Nov 22 19:18:37 <thurgood> did you set the partition to bootable?
Nov 22 19:18:51 <mn_> i've linux in my laptop..
Nov 22 19:19:02 <mn_> how to do that..?
Nov 22 19:20:03 <sam___> is Bafo BF-810 is compatible for Beaglebone Black serial debug pins ?Are you sure they don't destroy GND,Tx,RX pin On Beaglebone Black ?
Nov 22 19:20:04 <mn_> im new to use this board..
Nov 22 19:20:52 <thurgood> not entirely sure on windows but you should be able to do it through the disk management panel
Nov 22 19:21:17 <vinifr> mn_, there is a site, but in portuguese: http://sergioprado.org/desenvolver-sistema-linux-zero-beaglebone-black/
Nov 22 19:21:26 <thurgood> it may use the term active rather than bootable
Nov 22 19:27:34 <mn_> i didnt get it completely
Nov 22 19:27:46 <mn_> Can you tell now pls
Nov 22 19:32:51 <mn_> vinifr ??
Nov 22 19:33:30 <vinifr> Can Google Translate help you?
Nov 22 19:34:43 <vinifr> i can translate, but take a while :o
Nov 22 19:35:13 <mn_> Can I do in any other way like in linux
Nov 22 19:35:25 <mn_> Can I do dd
Nov 22 19:35:32 <mn_> to these files
Nov 22 19:35:51 <mn_> mailny I dont want linux to boot as of now
Nov 22 19:36:18 <sam____> is Bafo BF-810 is compatible for Beaglebone Black serial debug pins ?Are you sure they don't destroy GND,Tx,RX pin On Beaglebone Black ?
Nov 22 19:37:35 <mn_> @sam__ yes
Nov 22 19:37:56 <sam____> Thank You !!
Nov 22 19:38:35 <vinifr> i think you can use 'dd'
Nov 22 19:38:43 <thurgood> mn, in linux just use fdisk to set the paritition active/bootable
Nov 22 19:39:31 <mn_> in bootable partition if i write the MLO and uboot.img
Nov 22 19:39:42 <mn_> will it boot from sd
Nov 22 19:40:59 <thurgood> it should
Nov 22 19:41:12 <vinifr> mn_, http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Bootloader:U-Boot
Nov 22 19:42:35 <vinifr> http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSD/SDcard
Nov 22 19:44:16 <mn_> vinifr I dont know why he is using dd
Nov 22 19:44:35 <mn_> it is only making 0 of 1MB memory
Nov 22 19:46:04 <vinifr> erase SD memory
Nov 22 19:47:51 <vinifr> you must follow step by step
Nov 22 19:48:31 <vinifr> mn_, Setup microSD/SD card, Install Bootloader, uEnv.txt based bootscript
Nov 22 19:52:05 <mn_> is uEnv.txt is necesary
Nov 22 19:52:06 <mn_> ??
Nov 22 19:52:25 <mn_> I want to stop after the U boot propt only
Nov 22 19:53:40 <mn_> vinifr what is this http://pastebin.com/t2xXTb4i
Nov 22 19:53:45 <mn_> how to do that
Nov 22 19:54:47 <vinifr> it create 2 partitions
Nov 22 19:56:54 <vinifr> try type the whole command
Nov 22 19:58:21 <vinifr> EOF split the command in lines
Nov 22 20:00:21 <vinifr> for my particular board I use: (Format) http://rhombus-tech.net/allwinner_a10/a10_mmc_boot/
Nov 22 20:00:59 <mn_> ok
Nov 22 20:01:18 <mn_> I have created the two partitons
Nov 22 20:01:45 <mn_> and i have copied the MLO and uboot.img to the /dev/sdb1 partion
Nov 22 20:02:15 <mn_> do i need to create any boot directory in the /dev/sdb1
Nov 22 20:02:16 <mn_> ??
Nov 22 20:02:59 <vinifr> i think that is enough
Nov 22 20:03:02 <thurgood> nope,
Nov 22 20:03:16 <mn_> ok i will check it on the board once
Nov 22 20:06:43 <mn_> no....
Nov 22 20:07:12 <mn_> nothng is happening on the board
Nov 22 20:07:57 <vinifr> mn_, "uEnv.txt based bootscript"
Nov 22 20:08:51 <mn_> what is it compulsary to load the uboot from sd card
Nov 22 20:09:04 <mn_> when i press the boot button   CCCCCCCCCCCCCCCCCCCCCCCCCCCC
Nov 22 20:09:22 <mn_> this format is prining in tera term
Nov 22 20:09:58 <vinifr> mn_, sorry, uEnv.tx is only for load linux
Nov 22 20:10:08 <mn_> yes
Nov 22 20:10:09 <mn_> hmm
Nov 22 20:10:32 <vinifr> nothing? log?
Nov 22 20:10:43 <mn_> no log
Nov 22 20:10:53 <mn_> only CCCCCC are priniting
Nov 22 20:11:12 <vinifr> how did you compile images?
Nov 22 20:11:52 <vinifr> "make ARCH=arm CROSS_COMPILE=${CC} am335x_evm_config"?
Nov 22 20:12:04 <mn_>  make ARCH=arm CROSS_COMPILE=/myspace/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/arm-linux-gnueabihf-
Nov 22 20:12:07 <mn_> yes
Nov 22 20:12:10 <mn_> i did that
Nov 22 20:12:37 <mn_> after that i have given the above command
Nov 22 20:13:56 <mn_> is the first stage bootlade able to detect sd card and load the MLO??
Nov 22 20:14:05 <vinifr> strange! unfortunately I do not have a bbb
Nov 22 20:14:53 <thurgood> should be able to do that as it does for other boards like the xM
Nov 22 20:15:06 <mn_> hmm
Nov 22 20:16:09 <mn_> If I overwrite the emmc with my uboot from sd card
Nov 22 20:16:25 <mn_> I can boot my own image na
Nov 22 20:16:28 <mn_> ??
Nov 22 20:18:06 <vinifr> bbb is strange, because i use 'dd', not 'cp' in order to install uboot
Nov 22 20:18:18 <vinifr> in my board
Nov 22 20:18:33 <thurgood> yeah, but it sounds like you don't want to do that
Nov 22 20:18:52 <mn_> in dd how many files you have given
Nov 22 20:18:58 <vinifr> "dd if=spl/sunxi-spl.bin of=/dev/sdX bs=1024 seek=8"
Nov 22 20:19:10 <vinifr> "dd if=u-boot.bin of=/dev/sdX bs=1024 seek=32"
Nov 22 20:19:22 <vinifr> my board is cubieboard
Nov 22 20:19:23 <thurgood> the evm board is not the same as the bbb as far as I know... could be wrong there for the sake of MLO
Nov 22 20:20:08 <vinifr> yes, they are differents
Nov 22 20:20:47 <vinifr> both are arm, but still differents
Nov 22 20:21:08 <mn_> how to overwrite emmc image
Nov 22 20:21:09 <thurgood> same CPU line, but different boards
Nov 22 20:21:52 <mn_> i want to overwrite MLO and Uboot.img images in the emmc
Nov 22 20:22:01 <thurgood> it'd be like flashing a bios for one mobo onto a different mobo and hoping it works because they boath support the same CPU
Nov 22 20:23:03 <mn_> how to this any idea
Nov 22 20:29:38 <honestly> augh, which package is ptrace in in ubuntu?
Nov 22 20:31:56 <thurgood> try the command at the console, it will probably tell you the package if it's not already installed
Nov 22 20:32:43 <honestly> nope
Nov 22 20:32:52 <thurgood> hmm
Nov 22 20:33:30 <mn_> why my uboot.img is PPCimage
Nov 22 20:33:33 <thurgood> python ptrace?
Nov 22 20:33:37 <thurgood> python-ptrace?
Nov 22 20:33:40 <honestly> no.
Nov 22 20:34:00 <honestly> oh nvm
Nov 22 20:34:03 <honestly> ptrace is a system call
Nov 22 20:34:09 <mn_> [root@vijay mnt]# file u-boot.img u-boot.img: PPCBoot image
Nov 22 20:34:26 <honestly> I dun goofed
Nov 22 20:35:23 <thurgood> ah...
Nov 22 20:41:08 <nohearth2> dose any know the ubuntu 13.10 root password i try useing ubuntu ubuntu but it did not work.
Nov 22 20:46:44 <nohearth2> ow can one link one or more BBB together ?
Nov 22 20:47:15 <nohearth2> how *
Nov 22 20:48:15 <agmlego> Ethernet? SPI? I2C? RS232? USB? GPIB on the GPIO lines?
Nov 22 20:52:27 <nohearth2> ah ok thank you :) one last think thou i have a BBB with ubuntu 12.04.3 i log as ubuntu ubuntu but i just get the command line windowed how get to the normal ubuntu 12.04 desktop ?
Nov 22 20:56:28 <nohearth2> any one :O
Nov 22 20:59:22 <nohearth2> is any one running ubuntu are there BBB ?
Nov 22 20:59:25 <etch> nohearth2 I believe the default user is ubuntu and pass is temppwd. If you want a root user password, you can set one with sudo passwd
Nov 22 21:03:02 <nohearth2> allright i try temppwd  will it take just to the command line windowed or the  environment
Nov 22 21:04:01 <etch> nohearth2 never used a BBB with a monitor so I'm not sure. Always used the prompt
Nov 22 21:04:33 <nohearth2> ah ok  thank you etch
Nov 22 21:04:54 <nohearth2> can the BBB run Xbmc or no ?
Nov 22 21:05:53 <nohearth2> i got to go guy but thank  you for the help :D
Nov 22 21:06:03 <etch> i see no reason why it can't. UI won't be as snappy as a PC
Nov 22 21:06:05 <etch> np
