**** BEGIN LOGGING AT Mon Apr 14 03:00:00 2014
Apr 14 03:05:11 <nyt-> owl-v-: for what?
Apr 14 03:05:49 <nyt-> thats really vague.. what language? to what purpose?  there are tons of examples
Apr 14 03:12:05 <BobCat> my bbb always boots fron uSD too
Apr 14 03:12:13 <nyt-> same
Apr 14 03:12:15 <BobCat> no button press needed
Apr 14 03:21:02 <owl-v-> nyt-: C/C++ ( and maybe java later...)
Apr 14 03:21:51 <nyt-> get the adafruit bb io library
Apr 14 03:21:53 <nyt-> its python
Apr 14 03:21:59 <nyt-> but underlying layers are all done in C
Apr 14 03:22:03 <nyt-> so it will give you all you need to know
Apr 14 03:27:49 <foreverska> I can't seem to get making a flashing SD card right since I installed debian.  There's nothing extra weird about flashing debian back off BBB is there?
Apr 14 03:46:56 <learath> I have dumb questions.  How does the beaglebone black connectivity over USB work?
Apr 14 03:47:24 <learath> Is it stock linux drivers?
Apr 14 03:49:41 <nyt-> [    7.354938] usbcore: registered new interface driver rt2800usb
Apr 14 03:49:42 <nyt-> [    8.948272]  gadget: using random self ethernet address
Apr 14 03:50:16 <learath> Ok, and the serial and filesystem work the same way?
Apr 14 03:51:46 <nyt-> dont think theres console on usb
Apr 14 03:51:50 <nyt-> rest of it is usb mass storage i believe
Apr 14 03:53:18 <learath> something came up :) cdc_acm 2-3:1.2: ttyACM0: USB ACM device
Apr 14 03:53:36 <learath> (that's from the box the beaglebone is plugged into)
Apr 14 03:54:43 <nyt-> ah
Apr 14 03:54:44 <nyt-> look at that
Apr 14 03:54:46 <nyt-> it does
Apr 14 03:54:51 <nyt-> well there you go
Apr 14 03:55:00 <nyt-> gadget serial up on com7 on my pc hah
Apr 14 03:55:06 <learath> looks like it's Inventra HDRC USB Controller
Apr 14 03:55:17 <learath> Whatever that means :)
Apr 14 03:55:46 <nyt-> i dont have any activity on the usb serial port interestingly enough
Apr 14 03:56:23 <learath> showing up as ttyGS0 on my bbb
Apr 14 03:56:56 <learath> I've got an agetty running against it
Apr 14 03:57:40 <nyt-> what dist?
Apr 14 03:57:44 <learath> stock
Apr 14 03:57:46 <nyt-> ah
Apr 14 03:57:48 <nyt-> running debian
Apr 14 03:57:53 <nyt-> i stirpped a lot of stuff out of mine though
Apr 14 03:57:59 <nyt-> but only gettys are on ttyO0
Apr 14 03:58:01 <nyt-> and tty1
Apr 14 03:58:03 <learath> Angstrom v2012.12 (Core edition)
Apr 14 03:58:13 <nyt-> oooooold
Apr 14 03:58:28 <learath> this is only the second time I've powered it up.  an update is scheduled
Apr 14 04:04:47 <learath> Thanks
Apr 14 04:05:12 <nyt-> np
Apr 14 04:05:14 <nyt-> ugh shoot me
Apr 14 04:05:16 <nyt-> fucking hate writing docs
Apr 14 04:05:41 <learath> hah.  Join the club.
Apr 14 04:05:43 <learath> Sunday night?
Apr 14 04:06:00 <BobCat> Write a Gantt chart instead
Apr 14 04:06:03 <nyt-> yeaaaaaaaaa
Apr 14 04:06:13 <nyt-> writing rdoc for this gem i just wrote
Apr 14 04:06:14 <nyt-> painful
Apr 14 04:07:22 <learath> based on my experience with ruby code, I thought docs were incompatible
Apr 14 04:07:43 <nyt-> most ruby I find to be fairly well documented
Apr 14 04:08:09 <learath> hah.  wish I could trade you
Apr 14 04:20:44 <xyz__> anyone know beablebone can do PWM hysteresis control
Apr 14 04:22:33 <tbr> still haven't read the TRM and SRM?
Apr 14 04:23:38 <xyz__> from where I can get information about TRM and SRM
Apr 14 04:23:43 <xyz__> can you send the link
Apr 14 04:23:53 <xyz__> I checked spec sheet several time
Apr 14 04:24:17 <xyz__> ?
Apr 14 04:30:14 <xyz__> tbr?
Apr 14 04:32:34 <xyz__> tbr sorry....I read TMR but I didn't got information regarding PWM hysteresis control
Apr 14 04:33:09 <tbr> the TRM has several thousand pages...
Apr 14 04:33:45 <xyz__> I think only 92 pages ...please can you send me the link please
Apr 14 04:34:46 <tbr> http://bit.ly/1nm6aVx
Apr 14 04:37:29 <tbr> also you were given a link more than 6h ago:
Apr 14 04:37:33 <tbr> 20:43:41< veremit> http://elinux.org/Beagleboard:BeagleBoneBlack#LATEST_PRODUCTION_FILES_.28B.29
Apr 14 06:47:37 <jaw221> Hi guys, http://beagleboard.org/Support/BoneScript/#pin and #analogio anchors seem to have been removed... is there a handier reference for pins than the SRM?
Apr 14 06:48:57 <jaw221> Hmm, I guess http://beagleboard.org/Support/bone101/#headers is pretty handy
Apr 14 07:29:41 <jaw221> If I want to access /sys/bus/iio/.../in_voltageY_raw in C by way of open() and then mmap(), what length should I use as the 2nd argument to mmap?
Apr 14 07:32:44 <nyt-> it outputs a string so it can vary
Apr 14 07:33:10 <nyt-> up to 5 bytes i believe
Apr 14 07:33:25 <nyt-> not sure mmap is going to do for you what you want
Apr 14 07:33:33 <nyt-> might be better to fopen and frewind
Apr 14 07:42:41 <jaw221> I was thinking that. but won't I run into issues due to the volatility of those files? like, the value changing mid-read?
Apr 14 07:50:57 <atsampson> jaw221: no -- looking at the sysfs code, the kernel sticks the value into a buffer when you do a read that starts from 0, so you can read in as many chunks as you like and you'll always get a consistent result
Apr 14 07:51:22 <atsampson> http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/fs/sysfs/file.c#L115
Apr 14 07:57:18 <jaw221> nyt-, atsampson: thanks a bunch. does that mean I should just use fread, and the kernel will use sysfs_read_file to service fread?
Apr 14 07:58:51 <LetoThe2nd> jaw221: basically yes.
Apr 14 07:59:26 <LetoThe2nd> jaw221: have a look into LLD3, especially the fops chapter for some more detail.
Apr 14 08:00:44 <LetoThe2nd> *LDD3
Apr 14 08:02:42 <jaw221> hmm, I don't see that chapter https://lwn.net/Kernel/LDD3/
Apr 14 08:04:23 <LetoThe2nd> jaw221: 3.3 until end of chapter.
Apr 14 08:08:00 <jaw221> k, thanks very much
Apr 14 08:14:16 <heeen> does anyone know how musb_hdrc works
Apr 14 08:14:22 <heeen> tbr: ^
Apr 14 08:14:34 <heeen> specifically how to restart the usb subsystem
Apr 14 08:15:13 <tbr> unload / load
Apr 14 08:15:31 <heeen> is it a kernel module
Apr 14 08:15:32 <tbr> I don't know more, managed to avoid ever looking deeper.
Apr 14 08:15:35 <tbr> yes
Apr 14 08:15:47 <heeen> hm I don't see it
Apr 14 08:15:54 <tbr> maybe it's built in?
Apr 14 08:15:55 <heeen> I unplugged my hub, it still shows in lsusb
Apr 14 08:24:34 <_av500_> you see the root hub
Apr 14 08:24:36 <_av500_> always
Apr 14 08:24:39 <_av500_> pastebin
Apr 14 08:29:56 <nyt-> ugh
Apr 14 08:30:00 <nyt-> writing this rdoc
Apr 14 08:30:05 <nyt-> my eyes may or may not be bleeding
Apr 14 08:30:42 <nyt-> _av500_: published gem, just documenting now, should hopefully be complete either later tonight or tomorrow
Apr 14 08:30:45 <nyt-> depending on when i fall asleep
Apr 14 09:05:15 <RagBal> Can anybody recommend me a 5 inch capacitive touchscreen which has a device tree compatible driver for Linux?
Apr 14 09:06:04 <av500> I dont know any
Apr 14 09:06:42 <RagBal> Or just the touch controller =)
Apr 14 09:07:57 <av500> usb
Apr 14 09:08:04 <av500> no need for DT
Apr 14 09:12:15 <RagBal> I don't want a USB interface
Apr 14 09:14:18 <jacekowski> any screen used in a android phone
Apr 14 09:14:22 <jacekowski> an*
Apr 14 09:16:22 <RagBal> Hmm good idea jacekowski
Apr 14 09:16:35 <av500> good luck

Apr 14 09:21:29 <RagBal> av500, thank you for the suggestions, will have a look at them!
Apr 14 09:31:52 <philenotfound> av500: iirc chipsee has a non dt kernel
Apr 14 11:14:49 <ne0h> hi question is: can i use all gpio pins on beaglebone black for i/o?
Apr 14 11:15:09 <LetoThe2nd> no.
Apr 14 11:15:10 <jkridner> ne0h: not unless you disable HDMI and eMMC
Apr 14 11:15:30 <LetoThe2nd> ne0h: -> http://eskimon.fr/beaglebone-black-gpio-interactive-map
Apr 14 11:16:33 <djungel_crabz> "how hdmi Pin (for the display, can eventually be used as GPIO) ". "eventually" as in "alternatively"?
Apr 14 11:17:57 <ne0h> hmm...is it possible to disable pwm1a/b to use P9_14/16?
Apr 14 11:19:40 <LetoThe2nd> well they are shown as available, not?
Apr 14 11:21:06 <ne0h> i do not understand how the page you sent works, sorry
Apr 14 11:21:21 <ne0h> is there a button i have to press?
Apr 14 11:21:35 <LetoThe2nd> check the box: "show available pin"
Apr 14 11:21:36 <ne0h> after i marked e.g. "show availible pin"
Apr 14 11:22:04 <ne0h> i did so but there seems to be no effect
Apr 14 11:22:07 <LetoThe2nd> then the two pins you questioned get marked. so they should be available.
Apr 14 11:23:09 <ne0h> aaahh after page reload it works, thank you
Apr 14 11:23:41 <ne0h> this is pretty cool
Apr 14 11:24:38 <ne0h> and what can i do when gpio# is undefined? disable something else?
Apr 14 11:24:59 <Dan1> LetoThe2nd: whos page is that?
Apr 14 11:25:23 <LetoThe2nd> Dan1: no idea. you're free to find out for yourself
Apr 14 11:25:25 <av500> an eskimo
Apr 14 11:25:45 <Dan1> LetoThe2nd: ahh thought it might have been yours or something, its exactly what ive been wanting :)
Apr 14 11:25:47 <Dan1> cheers
Apr 14 13:00:58 <mistawright> so I saw that I am able to pre-order the beaglebone black with 4gb of emmc from seeedstudio's but its the embest version. Is there anywhere I can pre-order the 4gb version from circuitco?
Apr 14 13:01:46 <jkridner> http://www.digikey.com/product-search/en?lang=en&site=us&keywords=BB-BBLK-000-ND&WT.z_slp_buy=TI_BeagleBoard is the Rev C
Apr 14 13:02:16 <jkridner> look for Rev C in the order.
Apr 14 13:04:16 <mistawright> any expectation on shipping?
Apr 14 13:04:36 <mistawright> I know they ere expecting them to be manufactured by the end of april
Apr 14 13:25:05 <jkridner> I'd expect shipping in mid-May
Apr 14 13:38:13 <k-man> hi
Apr 14 13:39:42 <k-man> i deleted (well moved to MLO.old) the MLO file on the fat partion so the BBB would boot from the sd card automatically,  but now it doesn;t boot at all, it gets to uboot and give me this error:  ** File not found /boot/uImage **
Apr 14 13:39:50 <k-man> any idea how i can fix it
Apr 14 13:39:54 <k-man> lukily i have serial
Apr 14 13:40:36 <keesj> Did you remove the power between the rm and the test?
Apr 14 13:40:48 <k-man> yes
Apr 14 13:42:18 <keesj> It still can be uEnv.txt that points to the wrong device
Apr 14 13:42:31 <k-man> if i hold down the button and power on, i just get Cs continuously on the the serial port
Apr 14 13:42:34 <keesj> as http://ahsoftware.de/Beaglebone_Black_Boot_explained.svg shows
Apr 14 13:43:13 <keesj> yea that sounds like your sd-card is not properly done
Apr 14 13:43:49 <keesj> the CCC is the rom code waiting for serial upload
Apr 14 13:44:11 <k-man> yeah - it was a debian image i wrote to the sd card
Apr 14 13:44:16 <k-man> hmmm...
Apr 14 13:44:28 <k-man> can i move the MLO file back from within uboot?
Apr 14 13:45:19 <keesj> it's probably easier to boot something else.
Apr 14 13:45:37 <k-man> oh, like another sd card?
Apr 14 13:45:51 <keesj> the thing is that you want MLO/u-boot.bin loaded from sd-card and if you fix that problem ... no problem..
Apr 14 13:47:06 <k-man> ok - i don't have a way to boot it right now to fix it. so i either need working bootable image or a way to fix this one
Apr 14 13:48:05 <keesj> also check out the uEnv.txt it sometimes assumes "no button pressed" -> boot from internal hardware. while in this case it is not true
Apr 14 13:49:14 <k-man> ok but how to proceed now?
Apr 14 13:51:02 <keesj> so check the content of your sd-card's first partition ( uEnv.txt  )
Apr 14 13:51:45 <keesj> if you want to put back MLO you will need to download any sd-card image (arch linux for example) and move MLO back
Apr 14 13:52:15 <k-man> ok
Apr 14 13:54:42 <k-man> ok, turned out the MLO file i moved was on the sd card, not on the MMC
Apr 14 13:54:45 <k-man> emmc
Apr 14 13:55:00 <keesj> :P
Apr 14 13:55:01 <k-man> so i moved it back and it seems to have booted fine
Apr 14 13:55:13 <k-man> so i was wrong on may levels :-/
Apr 14 13:55:32 <k-man> thanks for your hellp keesj
Apr 14 13:55:40 <keesj> np
Apr 14 13:55:57 <k-man> now, now do i safely make this thing boot from the sdcard at power on?
Apr 14 13:56:06 <k-man> *how*
Apr 14 13:57:55 <LetoThe2nd> k-man: IIRC grounding pin 8_43 with a 10k resistor or such forces it to always boot from mmx
Apr 14 13:58:22 <LetoThe2nd> *mmc
Apr 14 13:58:58 <LetoThe2nd> you can read up on it, buzzword is SYSBOOT and the order defined by it.
Apr 14 13:59:18 <keesj> also modifing uEnv.txt can help (but MLO and u-boot will still be loaded from internal storage)
Apr 14 14:00:44 <k-man> ok, i don't mind that.
Apr 14 14:11:27 <keesj> k-man: so open the uEnv.txt and try to understand where to hack :P
Apr 14 14:13:28 <k-man> i did a but - then i felt a bit faint - then i decided to leave that problem for another day
Apr 14 14:13:39 <k-man> a bit, i mean
Apr 14 14:13:43 <k-man> typing not good
Apr 14 14:15:58 <k-man> ok, thats my nights hacking done, thanks for your help guys
Apr 14 14:16:00 <k-man> night
Apr 14 14:30:55 <dogrocket> anyone using the new debian think its a lot slower than older distrobutions?
Apr 14 14:31:19 <XorA> nope
Apr 14 14:31:53 <dogrocket> wonder if something didnt go right in install of data... hrm
Apr 14 14:32:55 <dogrocket> in console mode i can hit a key and actually see a bit of delay in character echo on screen :/
Apr 14 15:09:51 <yatharth> Hi I want to interface eink screen
Apr 14 15:11:11 <yatharth> omap 36xx application processors are extensively for epd
Apr 14 15:11:35 <yatharth> but I couldnt find any board based on omap 36xx application processor
Apr 14 15:14:05 <tbr> you want to interface which screen to what?
Apr 14 15:26:19 <dogrocket> i had heard t.i. has quit development of the omap processors, anyone know if they will continue to make the current omap lineup?
Apr 14 15:28:25 <ogra_> nope
Apr 14 15:28:50 <tbr> note that the beaglebone doesn't use an OMAP though
Apr 14 15:29:04 <ogra_> right
Apr 14 15:29:22 <dogrocket> we may need to go to OMAP if beagle doesnt support our needs
Apr 14 15:30:14 <dogrocket> throwing a lot of duties at the beagle, in the end dont know if it will handle it all
Apr 14 15:34:47 <tbr> mh, there are those automotive chips that are sort of omap based, but they don't get any community love
Apr 14 15:34:53 <tbr> jacinto or somesuch
Apr 14 15:35:43 <dogrocket> we are making a prototype audio system with beagle, but it will need to handle talking to a DAC, Wifi, and a separate Wifi audio chip, and of course database and web content pushing..
Apr 14 15:36:51 <dogrocket> big task for little beagle :O
Apr 14 15:38:21 <tbr> depends™. I'd be most concerned about the WiFi. Not the strong side of this hardware, unless you go for sdio, but that can do only one card
Apr 14 15:39:29 <dogrocket> i noticed the new wifi18xx chip uses both PRU's you think that will offload cpu a bit?
Apr 14 15:41:24 <dogrocket> no idea how much of cpu hog 18xx is, would be interesting to know before we buy it
Apr 14 15:42:22 <tbr> no idea
Apr 14 15:45:10 <myself> the automotive chips are usually hard to get datasheets for; the community's kinda SOL there
Apr 14 15:48:12 <dogrocket> hrm... i will have to check those out, thanks
Apr 14 15:53:38 <dogrocket> i know about lacking documentation on T.I. products, just got this dac and its not working right,  i dont know if its broke or im just not configuring it right
Apr 14 15:54:04 <dogrocket> codec rather
Apr 14 17:28:51 <mthiffau> Hello, anybody around with knowledge about configuring timers/clocks?
Apr 14 17:32:47 <mthiffau> Does anybody know what the frequency of CLK_M_OSC is on the beaglebone black, or how to go about finding out? It's not in the TRM, I think it's a platform specific thing
Apr 14 18:52:44 <techwiz> Hey guys, I have a question
Apr 14 18:52:59 <myself> congratulations! I had a question once.
Apr 14 18:53:04 <myself> I was so proud.
Apr 14 18:53:39 <techwiz> Great. Now are you going to continue to be sarcastic or should I wait for a more helpful community member
Apr 14 18:54:43 <mdp> see topic
Apr 14 18:54:55 <KotH> or see not, your choice
Apr 14 18:54:55 <mdp> 20 goto 10
Apr 14 18:54:58 <prpplague> techwiz: ask away! if someone is available, can help, and has time, they will...
Apr 14 18:55:12 <mdp> because the topic is not enough
Apr 14 18:55:18 <KotH> or continue to be sarcastic anyways
Apr 14 18:56:15 <techwiz> I have a beaglebone black that I think has blown it's power circuitry. What's the ETA for getting an RMA back in the mail? If possible could I pay for expedited shipping et al?
Apr 14 18:56:49 <KotH> i think you should ask that cco directly
Apr 14 18:57:17 <KotH> of the people in this channel only one works for cco and i am not sure he knows the answer
Apr 14 18:57:49 <techwiz> Who is CCO and how do I get in touch with said person
Apr 14 18:58:01 <prpplague> techwiz: you'll have to email the rma account
Apr 14 18:58:14 <KotH> techwiz: chircuitco the company behind the bbb
Apr 14 18:58:18 <prpplague> techwiz: it all depends on what's wrong with it  and how backed up they are
Apr 14 18:59:40 <prpplague> techwiz: http://elinux.org/Beagleboard:BeagleBoneBlack#RMA_Support
Apr 14 19:02:29 <prpplague> techwiz: no problem
Apr 14 20:37:00 <adnc_> hello, I've a beaglebone black and I would like to feed out the reset button to an enclosure I want to buidl the beaglebone into it. Are there any pins for reset reserved or do I have to solder to the button on the board?
Apr 14 20:47:09 <BeagleGithub> [kernel] RobertCNelson created 3.14 (+1 new commit): http://git.io/ebyyfA
Apr 14 20:47:09 <BeagleGithub> kernel/3.14 5b345e1 Robert Nelson: 3.14: update to v3.14.1...
Apr 14 20:56:34 <Vaizki> adnc_: yes there are pins and yes they are all listed in the system reference manual
Apr 14 20:57:24 <adnc_> Vaizki: there are lot of pins but is the reset fed out?
Apr 14 20:58:12 <Vaizki> yes
Apr 14 20:58:30 <adnc_> but where?
Apr 14 20:58:41 <Vaizki> do you really need me to look it up?
Apr 14 20:59:25 <adnc_> that would be nice since I can not find it in the system reference manual pdf
Apr 14 21:02:14 <Vaizki> https://github.com/CircuitCo/BeagleBone-Black/blob/master/BBB_SRM.pdf?raw=true
Apr 14 21:02:19 <Vaizki> P9.10
Apr 14 21:02:51 <adnc_> Vaizki: thank you very much. I'll read it
Apr 14 21:03:14 <Vaizki> also https://github.com/CircuitCo/BeagleBone-Black/blob/master/BBB_SCH.pdf?raw=true
Apr 14 21:04:58 <Vaizki> so basically GNDing P9.10 is the same as pressing the reset button
Apr 14 21:05:31 <adnc_> I must have been blind
Apr 14 21:05:52 <adnc_> Vaizki: great thank you very much. same applies to power button
Apr 14 21:06:00 <adnc_> P9.9
Apr 14 21:06:21 <Vaizki> yes
Apr 14 21:06:32 <adnc_> Vaizki: is it also possible to get the led fed out?
Apr 14 21:06:39 <adnc_> in particular the power led
Apr 14 21:09:12 <Vaizki> umm not directly but you have access to 3.3V and 5V system power on P9
Apr 14 21:10:33 <adnc_> I see, you mean hooking up an led to 3.3v and it gets light up when powered
Apr 14 21:10:33 <Vaizki> sleepy time&
Apr 14 21:10:39 <adnc_> thank you again
Apr 14 21:52:30 <Duffhurdhjn_huma> Hello I want to make a purchase. How do I trust beagleboard? How are you accountable for a faulty product?
Apr 14 21:53:14 <MLM> Duffhurdhjn_huma: return policy of wherever you bought it
Apr 14 21:54:26 <thurgood> how do you trust any store?
Apr 14 22:49:12 <foreverska> I keep trying to flash the angstrom flasher but it never seems to work.
Apr 14 22:49:55 <foreverska> I mean it goes on the SD card fine (dd) but the BBB refuses to boot to it.
Apr 15 01:05:12 <hm> can anyone tell me if I can connect to the bbb via the mini-usb port while powering it via the barrel jack?
Apr 15 01:05:25 <veremit> sure
Apr 15 01:07:42 <hm> can you explain please?
Apr 15 01:09:19 <myself> "sure" is an affirmative, considered casual in most of English usage. You can safely treat it as a "yes".
Apr 15 01:11:52 <hm> I meant an explanation on how it is ok to connect both of them at the same time.
Apr 15 01:12:37 <veremit> plug & go lol
Apr 15 01:12:59 <hm> thanx anyway
Apr 15 01:13:06 <honestly> myself: or as "no" when it's the answer to "do you mind?" :P
Apr 15 01:13:51 <myself> I'm not familiar with that usage, honestly, but I'll take your word for it. I try to be more clear, myself.
Apr 15 01:14:23 <myself> hm: A look at the board schematic will explain that. :)
Apr 15 01:15:12 <MLM> The board will only consume the current it needs. The two power supplies are isolated somehow so they don't blow each other up.
Apr 15 01:19:31 <hm> myself and MLM: thank you for your help. I will take a look at the schematic.
