Sep 12 03:12:11 <yates> what kernel version is this? https://rcn-ee.net/deb/testing/2014-09-03/lxde-4gb/BBB-eMMC-flasher-debian-7.6-lxde-4gb-armhf-2014-09-03-4gb.img.xz
Sep 12 03:12:36 <yates> and is it stable enough to try for prototype code?
Sep 12 03:16:15 <yates> is there a recommended method of delivering OS plus custom code? i was thinking of configuring my personal SD to taste, then creating a .gz file of the image for others to flash. is that reasonable?
Sep 12 03:57:20 <agmlego> ./c
Sep 12 09:16:39 <yates> i'm confused about the purpose of the "flasher" versus "standalone" images here: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Image_Testing_Snapshots
Sep 12 09:16:50 <av500> one flashes the image to emmc
Sep 12 09:16:52 <av500> the other does not
Sep 12 09:17:03 <av500> think "install" vs "live CD"
Sep 12 09:17:06 <yates> av500: right, but when would you ever use the one that does not?
Sep 12 09:17:28 <yates> how do you get the os onto the internal emmc?
Sep 12 09:17:33 <av500> I dont
Sep 12 09:17:37 <av500> I keep it on SD :)
Sep 12 09:17:57 <yates> ok, but then in that case you always have to boot while holding the button, right?
Sep 12 09:18:03 <av500> no
Sep 12 09:18:11 <av500> if there is nothing in emmc, it boots from SD
Sep 12 09:18:16 <av500> clever little thing
Sep 12 09:23:18 <yates> av500: how long does it take for yours to boot?
Sep 12 09:23:30 <av500> few seconds
Sep 12 09:24:10 <yates> less than 60?
Sep 12 09:25:14 <av500> probably
Sep 12 09:25:53 <yates> with probability > 0.85?
Sep 12 09:26:09 <KotH> p < 0.05
Sep 12 09:26:59 <yates> KotH: can you provide the probability density function for this random variable? :)
Sep 12 09:27:18 <KotH> it's av500 shaped
Sep 12 09:27:40 <yates> i see..
Sep 12 09:29:19 <av500> yates: boot times depends much on what you boot
Sep 12 09:29:26 <av500> Unity or command lind
Sep 12 09:29:27 <av500> line
Sep 12 09:29:28 <yates> i have a strange issue. when i boot with the usb plugged in, all is well.
Sep 12 09:29:49 <yates> however, when i boot without the usb plugged in, it comes up fine for about 5 minutes, then dies.
Sep 12 09:30:17 <yates> any ideas why?
Sep 12 09:30:34 <yates> this behavior is consistent.
Sep 12 09:30:53 <yates> and i'm booting from the external SD in both cases.
Sep 12 09:31:05 <tbr> yates: what is your power supply?
Sep 12 09:32:09 <yates> a PC PS, feeding 5V in on the expansion connector, which looks to me to the identical mode of having 5V on the dc input connector
Sep 12 09:34:10 <tbr> humor us and use the barrel connector. I believe we've told you before.
Sep 12 09:34:28 <tbr> also ensure that the 5V is stable
Sep 12 09:34:34 <tbr> try a different PSU
Sep 12 09:34:41 <yates> tbr: watch your assumptions.
Sep 12 09:35:18 <tbr> yates: why the aggressive stance?
Sep 12 09:36:05 <yates> in my hardware, the bbb is mounted on a large board performing other functions. it is necessary to have it operate with this board's power since the final application will not have a usb available.
Sep 12 09:36:36 <KotH> what tbr said still holds though
Sep 12 09:36:42 <KotH> try the barrel connector
Sep 12 09:36:52 <av500> +1
Sep 12 09:37:00 <KotH> feeding power from a random connector might not do what you expect it to do
Sep 12 09:37:48 <tbr> if you have a oscilloscope, observe your supply voltage
Sep 12 09:38:47 <KotH> tbr: observing power supply fluctuations with an oscilloscope is not something the average engineer should do... most dont know what to look for and how to be sure that what you measure is actually what is happening on the board
Sep 12 09:39:13 <KotH> also, a rigol will fail horribly at that task, as do most of the low-end oscilloscopes
Sep 12 09:40:04 <tbr> KotH: *nod*
Sep 12 09:42:33 <yates> KotH: i learned how to use a scope in my first trimester at DeVry.
Sep 12 09:43:22 <yates> what's magical about looking at DC power?
Sep 12 09:44:00 <yates> i guess you could have high frequency oscillations that you wouldn't see with a low-bandwidth scope.
Sep 12 09:44:07 <yates> e.g.
Sep 12 09:44:37 <KotH> well.. if you have to ask, you should not do it
Sep 12 09:44:43 <KotH> google for transient measurement
Sep 12 09:44:53 <yates> if you make the assertion, you should back it up.
Sep 12 09:45:43 <KotH> if you have ever measured signals with a BW in the GHz range, then you know where my assertions come from
Sep 12 09:45:50 <KotH> if not, learn about it first
Sep 12 09:45:56 <yates> yes, i've used LeCroys..
Sep 12 09:46:07 <KotH> using a tool does not make you an expert in it ;)
Sep 12 09:46:18 <KotH> also, lecroy has low end scopes as well ;)
Sep 12 09:46:38 <yates> KotH: well i guess you just piss farther than i.
Sep 12 09:46:39 <LetoThe2nd> plus, anybody claiming "i've learnt proper measurement in a trimester" is plain wrong.
Sep 12 09:46:56 <yates> PhD in Power Supply Measurements...
Sep 12 09:47:06 <LetoThe2nd> not from his own POV of course, but just from the experience that cannot be gathered in a few months.
Sep 12 09:47:16 <KotH> yates: really.. measuring transients on power supplies is black magic
Sep 12 09:47:26 <yates> no, of course not... this is really really fancy stuff, DC and all.
Sep 12 09:47:45 * yates hears "Spooky" in the background...
Sep 12 09:47:57 <KotH> yates: lots of cargo cult stuff and incantations to get it right... and in the end you still dont know whether you see an artifact of your measurement or something real
Sep 12 09:48:12 <LetoThe2nd> yates: believe it or not, properly measuring DC can be hard, once timing and capacitances come into play. and that is the case in such boards.
Sep 12 09:48:23 <KotH> also, if you dont see anything it does not mean there isnt something there
Sep 12 09:48:49 <LetoThe2nd> yates: if you don't believe it, google around a bit on what hoops people jump through to only measure power consumptions on modern PCBs
Sep 12 09:49:17 <LetoThe2nd> yates: and then from there on, think a bit about what is needed *on* *top* if you want to find problems in that said power consumption...
Sep 12 09:49:48 <LetoThe2nd> sure, anybody can hold a probe onto a pin and say "hey, that is 5V DC. measurement accomplished."
Sep 12 09:50:04 <LetoThe2nd> thats not real engineering life problem solving, though.
Sep 12 09:50:46 <KotH> LetoThe2nd: measure it with an 8.5 digit MM ;)
Sep 12 09:51:02 <yates> yeah, i wouldn't know anything about real-life engineering problems.
Sep 12 09:51:12 <LetoThe2nd> yates: i'm not saying that.
Sep 12 09:51:46 * tbr wonders if the board exhibits that behaviour when not connected to anything, just powered
Sep 12 09:52:19 <LetoThe2nd> yates: i just said: "when you clain to know how to properly measure power lines, and learned that in a few months at some educational institution, then chances are that you do not really know what you are talking about"
Sep 12 09:52:24 <LetoThe2nd> (no offense meant)
Sep 12 09:52:36 <yates> does the package adafruit sends the bbb in include a barrel power supply?
Sep 12 09:52:48 <yates> i've misplaced mine if so.
Sep 12 09:52:51 <yates> i think.
Sep 12 09:53:30 <tbr> no, PSU is always extra
Sep 12 09:54:09 <tbr> that way it doesn't drive up the price unnecessarily, as some people don't want more bricks for the pile or will power the board otherwise
Sep 12 09:54:56 <yates> do you know (i could look it up on the datasheet) what the AC input voltage range is on the TPS65217?
Sep 12 09:55:20 <yates> i have a wart ps that is 12 v...
Sep 12 09:55:27 <tbr> 'nope'
Sep 12 09:55:35 <tbr> the board takes 5V DC
Sep 12 09:56:05 <yates> guess i'll have to hack a cable and hook up my lab supply
Sep 12 09:56:08 <tbr> IIRC upper bound is 5.1 or 5.05. The SRM will know
Sep 12 09:57:18 <yates> so, if i do that, and the board behaves identically (i.e., hangs after 5 minutes), any conjectures on what would be happening?
Sep 12 09:58:13 <KotH> hardware or software bug
Sep 12 09:58:33 <tbr> then I would disconnect the board from whatever it's connected to and try again.
Sep 12 10:01:07 <yates> could it be an SD flash memory problem?
Sep 12 10:01:31 <av500> it can be anything
Sep 12 10:01:35 <av500> serial hooked up?
Sep 12 10:01:39 <yates> no
Sep 12 10:01:48 <av500> do it and observe when happens when it locks up
Sep 12 10:01:53 <av500> otherwise you are "blind"
Sep 12 10:02:06 <yates> well, i'd have to double check, but i don't think so.
Sep 12 10:02:41 <KotH> first rule about debugging problems: dont assume anything. always double check
Sep 12 10:02:56 <KotH> second rule about debuging problems: check the basics
Sep 12 10:03:15 <yates> that's basic... :)
Sep 12 10:03:52 <yates> PS, I'm stuck with a crappy Bitscope for a scope - I believe it's 100 MHz.
Sep 12 10:04:58 <yates> going back to bed... couldn't sleep...
Sep 12 10:05:19 <yates> thanks for your thoughts.
Sep 12 10:10:25 <yates> 20-V Tolerant USB and AC Inputs
Sep 12 10:33:51 <KJH> Does anyone know of a shop that still has the -XM board in stock?
Sep 12 10:59:09 <av500> KJH: how many do you need?
Sep 12 11:05:02 <hitlin37> anyone planning to go to ELC next month? I might go...
Sep 12 11:05:40 <av500> yes
Sep 12 11:05:44 <av500> at least one day
Sep 12 11:09:00 <hitlin37> great.
Sep 12 11:14:45 <hitlin37> first two days looks good to attend.
Sep 12 11:17:30 <KJH> @av500, Just the one.
Sep 12 11:19:20 <KotH> KJH: send av500 a big bar of good swiss chocolate
Sep 12 11:20:52 <KJH> Just give us his home address and a big bar of Swiss Chocolate will be on its way
Sep 12 11:21:52 <tbr> hitlin37: the usual people are going. this time including me.
Sep 12 11:22:23 <hitlin37> great.
Sep 12 11:22:32 <hitlin37> i might make it too.
Sep 12 11:23:38 <KotH> KJH: just type av500 into your phonebook app
Sep 12 11:23:54 <KotH> KJH: but be aware that av500 is spoiled. he only eats the best of the best of swiss chocolate
Sep 12 11:28:29 <KJH> Ok. But in seriousness - nobody knows a shop with an -XM in stock?
Sep 12 11:29:02 <av500> KJH: see my pm
Sep 12 12:10:17 <ritz> hi every one
Sep 12 12:11:20 <ritz> who isa this
Sep 12 12:12:05 <Rotti> hi
Sep 12 12:12:18 <ritz> whats ur name
Sep 12 12:13:22 <av500> ritz: please play somewhere else
Sep 12 12:13:23 <ritz> is there anyone
Sep 12 12:13:49 <ritz> i would like to chat ...
Sep 12 12:14:01 <av500> ritz: find some other place to chat
Sep 12 12:14:12 <ritz> mind ur bussiness
Sep 12 12:15:56 <KotH> ritz: watch your mouth
Sep 12 12:16:00 <notserpe> hi ritz, hows the crackers?
Sep 12 12:16:11 <ritz> fine ..
Sep 12 12:16:18 <iomari> greetings, I'm currently booting from sdcard with the debian image from chipsee direct. All is going well. Is it possible to flash the emmc with this?
Sep 12 12:16:31 <KotH> iomari: afaik yes
Sep 12 12:16:43 <KotH> iomari: there should be flasher images somewhere
Sep 12 12:16:57 <ritz> yes , u need to load flasher  image .
Sep 12 12:17:08 <av500> iomari: no idea about chipsee images
Sep 12 12:17:13 <av500> ask chipsee
Sep 12 12:17:24 <ritz> who is chipese
Sep 12 12:17:45 <iomari> I have flasher images but they are don't contain the drivers for the chipsee screen like the chipsee debian image does.
Sep 12 12:18:03 <iomari> chipsee makes the 7inch cape screen for BBB.
Sep 12 12:18:12 <ritz> angstrom image is good for ur answer
Sep 12 12:18:16 <av500> nonsense
Sep 12 12:18:27 <ritz> what nonsense  ha..
Sep 12 12:18:59 <iomari> ritz: I prefer debian
Sep 12 12:19:05 <ritz> k..
Sep 12 12:19:11 <av500> ritz: please say something useful or dont say anything
Sep 12 12:19:29 <ritz> i would like to make friends ...
Sep 12 12:19:54 <av500> ritz: you dont make friends like that here
Sep 12 12:20:00 <ritz> now u donot say ,this is not te plae  k
Sep 12 12:20:22 <ritz> thats what am abt to tel u yar..
Sep 12 12:20:23 <av500> iomari: you would need to add your drivers to the image that the flasher flashes
Sep 12 12:20:33 <av500> ritz: 1) please speak english
Sep 12 12:20:48 <av500> 2) stop the nonsense
Sep 12 12:20:55 <ritz> am telling u in english ..
Sep 12 12:20:59 <KotH> 3) insulting an op is a bad idea
Sep 12 12:21:08 <ritz> what is op
Sep 12 12:22:18 <ritz> is there anyone to  talk to me
Sep 12 12:22:20 <av500> ritz: please read this: http://www.mahdiyusuf.com/post/6176918750/survival-guide-irc-1
Sep 12 12:22:24 <av500> ritz: and follow it
Sep 12 12:22:27 <av500> last warning
Sep 12 12:22:51 <ritz> whats wrong with u
Sep 12 12:23:47 <iomari> fav500: that was the problem I had yesterday. All the info I found for the chipsee lead nowhere. I eventually found the compete image on their site which works perfectly from sd. Now I want to flash then use sd as storage.
Sep 12 12:24:08 <av500> so
Sep 12 12:24:13 <av500> take apart the flash image
Sep 12 12:24:20 <av500> find that part that it flashes
Sep 12 12:24:25 <av500> and put the chipsee image there
Sep 12 12:24:27 <av500> hope that it works
Sep 12 12:24:37 <av500> or, much more easy: keep running from SD and be happy
Sep 12 12:24:44 <iomari> av500: sounds like a plan. thanks.
Sep 12 12:25:20 <iomari> av500: I thot running form emmc would be faster.
Sep 12 12:25:43 <av500> ah well
Sep 12 12:25:51 <av500> not really
Sep 12 12:25:58 <av500> emmc is an sdcard soldered to the PCB
Sep 12 12:26:23 <iomari> av500: then that settles it. Can the emmc be used as storage.
Sep 12 12:26:38 <av500> yes
Sep 12 12:26:47 <av500> but your random sd card has probably more storage
Sep 12 12:26:54 <av500> vs the 2 or 4GB on board
Sep 12 12:28:34 <s> how to use beagle bone seria lport
Sep 12 12:29:37 <Guest19006> plaese let me know
Sep 12 12:30:00 <Guest19006> let me know
Sep 12 13:08:25 <iomari> is there an onscreen keyboard when using chipsse display and debian?
Sep 12 13:10:01 * KotH doubts that
Sep 12 13:10:12 <KotH> unless you started a specif app that does that
Sep 12 14:17:10 <chandan__> hey
Sep 12 14:17:37 <Guest66157> i want to know how can i connect normal audio cap with beaglebone black
Sep 12 14:24:55 <Guest66157> hey i want to know how can i connect normal audio cap with beaglebone black
Sep 12 14:25:52 <agmlego> YOu asked that already.
Sep 12 14:26:24 <Guest66157> yaa but know one answed that question
Sep 12 14:26:40 <agmlego> ...you waited seven minutes.
Sep 12 14:26:53 <agmlego> PLease read the topic.
Sep 12 14:27:14 <Guest66157> means
Sep 12 14:28:24 <Guest66157> ok
Sep 12 14:57:36 <kaczor> hi all
Sep 12 14:58:16 <kaczor> I'm using Debian image on microSD. Does anyone know how can I disable the splash screen(penguin) during the boot ?
Sep 12 14:58:56 <kaczor> I'ts not loading till the login screen (get's stuck on this penguin splash) and I don't know what can be wrong
Sep 12 15:04:28 <sheridp> Hi, does anyone have experience using SPI on the BBB directly via mmap?
Sep 12 15:05:28 <tbr> kaczor: sounds rather like you want to attach to the serial console
Sep 12 15:10:09 <kaczor> tbr thanks this might help but I would need to have some extra equipment. it's not possible to disable this splash and see the regular boot process ? (I don't know maybe some flag in  the /boot/uboot/uEnv.txt ?)
Sep 12 15:10:39 <tbr> kaczor: I don't know if the kernel is compiled with fb-console
Sep 12 15:11:27 <kaczor> ahh ok. in that case guess I'll have to buy a serial cable for it
Sep 12 15:11:56 <tbr> you could also check the kernel config and recompile if necessary
Sep 12 15:12:20 <tbr> also you could just mount the sdcard on your pc and look for psplash or whatever is used for it
Sep 12 15:12:22 <KotH> kaczor: you want to have the serial cable anyways. the serial console is the way how you debug stuff on embedded systems
Sep 12 15:12:33 <tbr> but yeah, what KotH says
Sep 12 15:12:49 <woglinde> hm somebody should put it in the topic
Sep 12 15:13:04 <KotH> woglinde: what exactly?
Sep 12 15:13:16 <woglinde> ask your question about booting, when you own a serial cable and know how to use it
Sep 12 15:13:25 <KotH> hehe
Sep 12 15:13:30 <KotH> a bit long
Sep 12 15:13:34 <woglinde> hm yes
Sep 12 15:13:36 <KotH> dunno whether that will fit
Sep 12 15:13:44 <tbr> boot problems? get a UART cable!
Sep 12 15:13:52 <woglinde> tbr yes nice
Sep 12 15:14:21 <KotH> meh..
Sep 12 15:14:51 <tbr> can we drop the production issues? I think that's no longer the case?
Sep 12 15:15:43 <woglinde> tbr right
Sep 12 15:15:54 <woglinde> there was none asking it in a month
Sep 12 15:18:41 <mistawright> so has anyone used there beaglebone black to create a rtsp stream that does not require an sdp file?
Sep 12 15:21:50 <woglinde> mistawright hm wrong channel?
Sep 12 16:01:44 <iomari> anyone know of any good virtual keyboards for debian on BBB?
Sep 12 16:03:06 <woglinde> iomaro you mean for X-server?
Sep 12 16:09:04 <tee_jay7> I upgraded from kernel 3.2 to 3.15 and now I have no /proc/driver/musb_hdrc.0 entry.
Sep 12 16:09:19 <tee_jay7> Does this mean something to anyone?
Sep 12 16:10:53 <iomari> woglinde: yes
Sep 12 16:12:03 <iomari> i installed florence but it looks distorted. some of the buttons are all black.
Sep 12 16:22:01 <milad> hi, when i compile a qt application with hard float toolchain, does the latest debian image in beagleboard site support hard float?
Sep 12 16:23:02 <milad> i mean does it use the float registers on the board!
Sep 12 17:32:21 <Guest97392> hey, In beaglebone black usb port is connected by spi or i2c connection ?
Sep 12 17:32:37 <Humpelstilzchen> I hope not
Sep 12 17:32:53 <Humpelstilzchen> I hope its connected with usb
Sep 12 17:33:21 <Guest97392> yaa ..but usb connection is used which one i2c or sp1
Sep 12 17:35:59 <Humpelstilzchen> I'm not sure if I - or someone else here - do understand your question
Sep 12 17:36:15 <Humpelstilzchen> how do you want to combine usb and i2c/spi?
Sep 12 17:47:10 <_av500_> Guest97392: niether i2c nor spi
Sep 12 17:47:13 <_av500_> neither
Sep 12 17:47:18 <_av500_> usb is native to the SoC
Sep 12 17:48:18 <Guest97392> ok
Sep 12 18:12:39 <Guest19567> hi, i want to interface cmos camera using i2c (not usb) with beaglebone black.how can i do that?
Sep 12 18:13:12 <_av500_> i2c?
Sep 12 18:13:24 <_av500_> what camera is that?
Sep 12 18:15:04 <Guest19567> cmos camera
Sep 12 18:15:57 <Guest19567> something like this http://www.uctronics.com/640x480-03mega-pixel-cmos-camera-module-ov7660-sccb-i2c-compatible-ov7670-p-231.html
Sep 12 18:17:08 <_av500_> ah yes
Sep 12 18:17:17 <_av500_> so, it is an I2C device
Sep 12 18:17:24 <Guest19567> so how can i do that
Sep 12 18:17:30 <Humpelstilzchen> uhm I doubt that its sends the image over i2c
Sep 12 18:17:33 <_av500_> google beaglebone and i2c and you will learn how to access I2C devices
Sep 12 18:17:37 <_av500_> Humpelstilzchen: it does
Sep 12 18:17:43 <Humpelstilzchen> you sure?
Sep 12 18:17:49 <_av500_> there were UART based cams too
Sep 12 18:18:05 <_av500_> sparkfun had them for the 'duino crowd
Sep 12 18:18:20 <_av500_> its 0.3MP
Sep 12 18:18:31 <Guest19567> ok
Sep 12 18:18:46 <Guest19567> https://www.sparkfun.com/products/11745  ?
Sep 12 18:19:05 <Humpelstilzchen> _av500_: actually looks more like i2c is control interface only
Sep 12 18:19:19 <_av500_> Guest19567: no, this is Video out
Sep 12 18:19:53 <_av500_> Humpelstilzchen: ah you are right
Sep 12 18:19:59 <_av500_> its 8bit data
Sep 12 18:20:00 <_av500_> my bad
Sep 12 18:20:04 <_av500_> not like the UART one
Sep 12 18:20:19 <_av500_> Guest19567: so, not so easy then
Sep 12 18:20:26 <_av500_> you need to bang some bits too
Sep 12 18:20:34 <Guest19567> ohk
Sep 12 18:20:52 <Humpelstilzchen> Guest19567: Why don't you get an USB Webcam? Way simpler
Sep 12 18:21:03 <Guest19567> i m going for i2c insted of usb bcz usb will be slow ? Is this so ?
Sep 12 18:21:03 <agmlego> Or an Ethernet one. ;-P
Sep 12 18:21:12 <agmlego> Guest19567: USB >>>> I2C
Sep 12 18:21:20 <_av500_> Guest19567: it is NOT I2C
Sep 12 18:21:21 <agmlego> In terms of speed.
Sep 12 18:21:26 <agmlego> I2C is really, really slow.
Sep 12 18:21:29 <_av500_> i2c is for control only
Sep 12 18:21:36 <_av500_> agmlego: try gigI2C :)
Sep 12 18:21:48 <agmlego> _av500_: Dear $deity, all the skew.
Sep 12 18:21:51 <agmlego> ::shudders::
Sep 12 18:22:08 <Guest19567> what about spi comapre to usb.. usb > > spi ?
Sep 12 18:22:15 <_av500_> yes
Sep 12 18:22:17 <agmlego> Generally, yeah.
Sep 12 18:22:28 <Guest19567> ohk
Sep 12 18:22:49 <_av500_> hmm, too bad, I wanted an I2C camera :)
Sep 12 18:23:03 <agmlego> Guest19567: THis is all pretty easily gotten from the respective Wikipedia articles on the protocols you are talking about. ;-P
Sep 12 18:23:40 <Guest19567> actully i want to interface two camera with bbb
Sep 12 18:23:48 <woglinde> good luck
Sep 12 18:23:55 <Guest19567> bbb usb can handle 2 camera?
Sep 12 18:24:07 <agmlego> Guest19567: I2C is either 100kHz or 400kHz, with one bit sent per clock. SPI is generally around 20MHz or so, with one bit sent per clock. USB is more complex, but can theoretically hit mid to high hundreds of megabits per second.
Sep 12 18:24:27 <agmlego> Guest19567: Define "handle"
Sep 12 18:24:34 <agmlego> YOu certainly can connect two.
Sep 12 18:24:41 <agmlego> YOu can probably pull image data off two.
Sep 12 18:24:53 <agmlego> YOu might even get more than single-fps performance off two.
Sep 12 18:24:56 <_av500_> the answer is: "it depends"
Sep 12 18:24:58 <Humpelstilzchen> agmlego: actually since your Master does the clock you have more speed options
Sep 12 18:25:00 <Guest19567> handle means it can do processing with two cmaeras
Sep 12 18:25:11 <agmlego> Humpelstilzchen: I am aware.
Sep 12 18:25:34 <agmlego> Guest19567: How fast? What processing? What size image? Are they color? Is the bone doing anything else?
Sep 12 18:25:44 <Humpelstilzchen> Guest19567: whats your use-case?
Sep 12 18:26:00 <_av500_> "...some light image processing..."
Sep 12 18:26:52 <Guest19567> like object regonization ?
Sep 12 18:27:05 <_av500_> we are asking you
Sep 12 18:27:21 <Guest19567> object recognization type thing
Sep 12 18:27:34 <agmlego> Guest19567: Object recognition using which algorithms? BLob finding? Watershed? Hough transforms? FFT? COlor analysis?
Sep 12 18:27:38 <Guest19567> i want it should take less then 1 sec
Sep 12 18:27:45 <_av500_> and did you try?
Sep 12 18:27:46 <agmlego> Per frame? Per analysis?
Sep 12 18:27:48 <_av500_> with a still image?
Sep 12 18:27:54 <_av500_> no need for a camera
Sep 12 18:28:00 <Humpelstilzchen> less send 1 sec, so you are fine with 1fps?
Sep 12 18:28:09 <Guest19567> ya
Sep 12 18:28:15 <_av500_> and did you try?
Sep 12 18:28:17 <_av500_> with a still image?
Sep 12 18:28:29 <Guest19567> i want 2-3 pfs
Sep 12 18:28:35 <_av500_> did you try?
Sep 12 18:28:40 <Guest19567> yaa...
Sep 12 18:28:43 <_av500_> and?
Sep 12 18:28:47 <Guest19567> with only one webcam
Sep 12 18:28:52 <Guest19567> and it was working
Sep 12 18:28:53 <_av500_> on BBB?
Sep 12 18:28:55 <Guest19567> ya
Sep 12 18:29:01 <agmlego> Then try two.
Sep 12 18:29:01 <_av500_> good
Sep 12 18:29:05 <Guest19567> using usb
Sep 12 18:29:08 <agmlego> And get back to us on the results.
Sep 12 18:29:30 <Guest19567> i have to give extra supply if i m connecting two webcam
Sep 12 18:29:43 <agmlego> Yeah, probably.
Sep 12 18:29:51 <Guest19567> ohk
Sep 12 18:29:59 <agmlego> Generally a poor decision to power USB devices from the bone anyway.
Sep 12 18:30:14 <Guest19567> ohk
Sep 12 18:30:42 <Guest19567> actully i also have to use a audio jack  with two webcam
Sep 12 18:31:01 <agmlego> So?
Sep 12 18:31:27 <Guest19567> what u think if i connect all of them with usb , then it will be gud thing or should i connect some one with other usb or spi?
Sep 12 18:31:47 <Guest19567> means i2c or spi
Sep 12 18:32:11 <Humpelstilzchen> Guest19567: try with USB first
Sep 12 18:33:07 <Guest19567> some one told me don't use usb it will be show, conect 2 camera and sound jack with i2c or spi. this this cool ?
Sep 12 18:33:33 <agmlego> Guest19567: I think the trouble here is, is you keep trying to think of USB, I2C, and SPI as equivalent data busses. THey really, really are not, and I *strongly* recommendreading the Wikipedia pages for each, in your native language and then in English, until you understand why.
Sep 12 18:34:59 <Guest19567> ohk
Sep 12 18:36:31 <agmlego> Maybe if you told us more of what your project actually is, we could be more useful to you.
Sep 12 18:36:40 * m_billybob looks for firewire implementation over UART
Sep 12 18:37:35 <Guest19567> actully i want to process the image with webcam and give the output using sound jack in 'Ear Phone '
Sep 12 18:37:48 <agmlego> What output?
Sep 12 18:38:14 <Humpelstilzchen> and what jack?
Sep 12 18:38:59 <Guest19567> after proocessing some image like a red ball , i tell user there is rad ball in Ear phone
Sep 12 18:39:13 <agmlego> Ah.
Sep 12 18:40:04 <Guest19567> <agmlego > for this i m making a project
Sep 12 18:40:56 <agmlego> Well, yeah, audio output is pretty easy to do either with a USB sound card or using the onboard audio hardware on the bone. THe bone supports I2S, or you could use the audio cape which appears to use I2C and SPI.
Sep 12 18:41:51 <Humpelstilzchen> well one thing at a time, first image processing then audio
Sep 12 18:41:51 <Guest19567> how can i connet audio cape in i2c oe spi
Sep 12 18:42:41 <_av500_> you cannot
Sep 12 18:42:52 <_av500_> please stop throwing random buzzwords around
Sep 12 18:42:55 <_av500_> educate yourseld
Sep 12 18:42:58 <_av500_> yourself
Sep 12 18:43:08 <_av500_> in this day and age, it is very easy to do so
Sep 12 18:43:52 <Guest19567> nop i m asking for device like this which i serach for usb https://www.google.co.in/search?q=logitech+usb+to+3.5mm+jack+audio+adapter&newwindow=1&biw=1366&bih=667&source=lnms&tbm=isch&sa=X&ei=xwUTVIy1B8yPuASd_YHoDw&ved=0CAYQ_AUoAQ
Sep 12 18:44:05 <Guest19567> like this or spi or i2c
Sep 12 18:44:08 <_av500_> yes, that is one option
Sep 12 18:44:16 <_av500_> STOP with I2C and SPI
Sep 12 18:44:37 <_av500_> please stop throwing random buzzwords around
Sep 12 18:44:45 <_av500_> go educate yourself
Sep 12 18:44:46 <Guest19567> ohk
Sep 12 18:45:28 <Guest19567> by educate means what?
Sep 12 18:45:41 <_av500_> I give up
Sep 12 18:45:46 <_av500_> have a nice day
Sep 12 18:46:01 * _av500_ answers only to his beer from now on
Sep 12 18:46:11 <m_billybob> heh
Sep 12 18:46:21 <Guest19567> please tell bro
Sep 12 18:46:28 <m_billybob> I bet you'd answer to mine if i sent you one :P
Sep 12 18:46:48 <Guest19567> ok
Sep 12 18:46:59 <m_billybob> Guest19567, you're being difficult, go educate yourself
Sep 12 18:47:32 <agmlego> Guest19567: Stop talking here, right now, and read the WIkipedia pages on USB, I2C, and SPI. DO not come back until you fully understand all three, and why you continually treating them as equivalent is pissing off the people you are trying to get help from.
Sep 12 18:48:05 <agmlego> Guest19567: Seriously, everyone here is starting to hate you a little because you are refusing to do anythign yourself.
Sep 12 18:48:37 <_av500_> Guest19567: free education: https://www.youtube.com/watch?v=vvoGic3eig0
Sep 12 18:49:12 <Guest19567> thanks
Sep 12 19:22:52 <bborg_builds> build #36 of runtests started (including [ed929a1234cdb21a07d9f8034277073e9cfa7976, 45aada52ba79c50ea8bdd366ab37e163067fa44e] and 43 more)
Sep 12 19:37:43 <Young_> Hi
Sep 12 19:39:44 <bborg_builds> build #36 of runtests is complete: Success [build successful]  Build details are at http://builds.beagleboard.org/builders/runtests/builds/36
Sep 12 19:57:02 <bgamari> It would be really nice if uboot ignored the value of the $(dtb) variable if USER is pressed
Sep 12 19:57:25 <_av500_> patch it
Sep 12 19:57:42 <bgamari> _av500_, I will do so once I can boot again
Sep 12 19:57:59 <bgamari> it may be easier to just start with a new installation
Sep 12 20:00:35 <bgamari> _av500_, Do you know which repository the uboot configuration is tracked in?
Sep 12 20:08:39 <_av500_> in uboot git
Sep 12 20:08:40 <_av500_> no?
Sep 12 20:08:48 <_av500_> BBB is fully supported there
Sep 12 20:08:58 <_av500_> should be all there
Sep 12 20:09:02 <_av500_> Tartarus: ^^^^
Sep 12 20:16:17 <Tartarus> Right
Sep 12 20:16:20 <Tartarus> mainline is good
Sep 12 20:16:41 <Tartarus> If the user button is pressed on BBB the HW boots from SD not emmc
Sep 12 20:16:49 <Tartarus> So you can do whatever you like in uEnv.txt
Sep 12 20:16:53 <Tartarus> since that'll be read and parsed
Sep 12 20:16:59 <Tartarus> you can re-whack fdtfile
Sep 12 20:17:04 <Tartarus> hardcode a new bootcmd into uenvcmd
Sep 12 20:17:08 <Tartarus> Go crazy :)
Sep 12 20:39:57 <challinan__> anyone around this friday? I'm trying to boot a black via microSD.  Holding down the boot switch during a power cycle, as in the manual, results only in a continuous display of 'C' characters on the FTDI serial console. It boots find from eMMC.  Any idea what I'm doing wrong?
Sep 12 20:40:25 <veremit> CCCC means its not seeing the uSD .. have you tried to re0write it
Sep 12 20:40:31 <veremit> or check its readable in another reader?
Sep 12 20:40:42 <veremit> you shuol dbe able to see the FAT partition even in windoze
Sep 12 20:40:58 <challinan__> or a mac even ;)
Sep 12 20:41:05 <challinan__> i'll check, thanks for the info
Sep 12 20:41:52 <challinan> hmm, don't know why my nick was decorated with __
Sep 12 20:42:16 <pumapops> does anyone know how capable the beaglebone black rev c would be at running a small phpbb installation
Sep 12 20:42:45 <veremit> puma .. theoretically possible .. but performance wouldn't be too good .. depends on how many users I guess
Sep 12 20:43:28 <pumapops> users would be about 20 max registered and maybe 7 or 8 max online at the same time
Sep 12 20:45:36 <challinan> veremit: my uSD is readable.  is the partitioning critical, i.e. must the FAT partition be a particular size? It contains MLO-beaglebone and u-boot.img
Sep 12 20:46:05 * challinan arbitrarily made it 128MB
Sep 12 20:46:12 <veremit> its better if its an even number of flash blocks
Sep 12 20:46:16 <veremit> round* number
Sep 12 20:46:35 <veremit> might be worth just having a quick look at Rob Nelson's page at eewiki.net for how he does it
Sep 12 20:47:17 <veremit> CCCC on console means its not finding U-boot if I recall correctly
Sep 12 20:47:23 <challinan> ah, thanks. I have a dozen tabs open already, but missed that one.  I formatted according to the release notes on yoctoproject.org, which is how I built my image
Sep 12 21:14:37 <challinan> ah ha.  Rob's instructions worked. thanks veremit, now I'm getting errors I know how to handle ;)
Sep 12 21:15:06 <veremit> awesome .. good stuff.. welcomes
Sep 12 22:15:17 <sheridp_> Does anyone know which of the SPI drivers from https://github.com/beagleboard/linux/tree/3.8/drivers/spi the beaglebone black uses?  (repeating because of server split)
Sep 12 22:16:13 <_av500_> spi-omap2-mcspi.c
Sep 12 22:16:15 <_av500_> I guess
Sep 12 22:17:05 <sheridp_> thanks
Sep 12 22:17:17 <_av500_> it was last touched by mdp here :)

Sep 13 01:01:40 <yates> i'm having a problem with my beaglebone black dying about 5 minutes after power-up when powered over the connector (via P9-5 and P9-6)
Sep 13 01:02:02 <yates> when powered over usb, or from a lab supply via the ac adapter input, things are fine
Sep 13 01:02:45 <yates> for the first five minutes over the expansion connector, everything works fine - can ssh, etc.
Sep 13 01:03:15 <yates> this power is supplied by a PCATX power supply and i've tried two power supplies now - both act the same.
Sep 13 01:03:38 <yates> any ideas?
Sep 13 01:03:52 <yates> rev c, btw.
Sep 13 01:04:03 <yates> running deb 3.8
Sep 13 01:04:44 <yates> shouldn't applying +5v at P9-5 and 6 be identical to supplying 5v to the ac adapter input?
Sep 13 01:04:54 <yates> it's the same node on the schematic!
Sep 13 01:09:42 <yates> ?
Sep 13 01:16:12 <yates> if something was hanging on one of the MMC1_xyz signals on P8, would that hose the BB?
Sep 13 01:16:30 <yates> isn't that the bus to the microSD?
Sep 13 01:23:19 <yates> if something was hanging on one of the MMC1_xyz signals on P8 on a beaglebone black rev c, would that hose the BB?

Sep 13 01:40:05 <yates> i'm not familiar with it...
Sep 13 01:40:55 <yates> can i go watch a Star Trek TOS episode on my big screen, then?
Sep 13 01:41:05 <yates> (my idea of a wild Friday night...)
