Jul 01 04:51:21 <Guest27879> cant open cloud9 any suggestions ?
Jul 01 04:54:57 <AE7IK> Bigger hammer.
Jul 01 06:03:59 <jaw221> hello everybody! I would like to "factory reset" my BBB Rev C by flashing the debian image, but the images at <http://beagleboard.org/latest-images> are explicitly labeled "2GB" whereas my BBB has a 4GB eMMC. Will this cause a problem?
Jul 01 06:04:43 <vagrantc> you can resize it once you install it
Jul 01 06:05:50 <vagrantc> jaw221: that just allowed the images to fit on both the old 2GB (although just *barely*) eMMC and SD cards...
Jul 01 06:06:12 <vagrantc> i.e. you can always use a smaller image in a larger space, ut the other way around has issues :)
Jul 01 06:10:10 <jaw221> are there directions for resizing?
Jul 01 06:13:16 <tbr> "like on any linux distro"
Jul 01 06:21:21 <jaw221> ok, thanks
Jul 01 06:22:30 <vagrantc> there's also a script in /opt/
Jul 01 06:23:08 <vagrantc> /opt/scripts/tools/grow_partition.sh
Jul 01 06:24:11 <jaw221> excellent, thank you
Jul 01 06:40:01 <jaw221> I would have tried fdisk
Jul 01 06:50:58 <vagrantc> you could do it manually, fdisk, resize2fs, etc.
Jul 01 08:04:46 <demeteor> Hey guys , I was here last day asking something about services. I have manage to make the service work. and do what it must do. but even though i follow what the guides say on the internet it does not start on boot .
Jul 01 08:04:53 <demeteor> can samone help ?
Jul 01 08:07:12 <_av500_> so the script works now?
Jul 01 08:07:29 <_av500_> pastebin the systemd unit
Jul 01 08:08:33 <_av500_> and the output of systemctl status <yourservice>
Jul 01 08:09:49 <demeteor> okay
Jul 01 08:09:51 <demeteor> give me a sec
Jul 01 08:12:47 <demeteor> I have actually made it from the bash file to go directly to root folder so i would not have to change the .service  here is the link http://pastebin.com/rR54A9KB
Jul 01 08:19:19 <_av500_> so its running now?
Jul 01 08:19:30 <demeteor> yes but it does not start at boot
Jul 01 08:19:50 <_av500_> so what is the systemctl status after boot?
Jul 01 08:20:13 <demeteor> I have to type systemctl start autocamera.service for it to start
Jul 01 08:20:20 <_av500_> so what is the systemctl status after boot?
Jul 01 08:20:28 <demeteor> the one i pasted
Jul 01 08:20:39 <demeteor> let me reboot with otu running it and check
Jul 01 08:20:57 <_av500_> well yes
Jul 01 08:21:08 <_av500_> if you start it manually as well, of course it runs
Jul 01 08:22:27 <demeteor> okay yea there is an error . but I dont understand it http://pastebin.com/uBE87hXn
Jul 01 08:23:02 <demeteor> the date seems to be wrong 14 years ago?
Jul 01 08:26:56 <_av500_> yes, its at early boot, no time yet
Jul 01 08:27:00 <_av500_> via ntp
Jul 01 08:27:05 <_av500_> so, you run to early
Jul 01 08:27:13 <_av500_> before your usb camera is there
Jul 01 08:28:24 <tbr> might want to define some dependencies
Jul 01 08:28:38 <_av500_>  10:07 <         _av500_@> pastebin the systemd unit
Jul 01 08:29:07 <demeteor> what do you mean by system unit ?
Jul 01 08:29:15 <_av500_> the thing you wrote
Jul 01 08:29:27 <demeteor> in the autocamera.service ?
Jul 01 08:29:37 <_av500_> yes, the service
Jul 01 08:29:41 <demeteor> its pasted on the 1st link . bellow the status
Jul 01 08:29:45 <demeteor> let me re paste it
Jul 01 08:30:01 <_av500_> ah
Jul 01 08:30:03 <_av500_> got it
Jul 01 08:30:18 <demeteor> okay
Jul 01 08:31:22 <_av500_> so, now do some googling to find out how to make a systemd service start after a usb device is attached
Jul 01 08:31:37 <_av500_> because in fact you dont want to start at boot
Jul 01 08:31:45 <_av500_> but when the camera is plugged/detecgted
Jul 01 08:32:17 <demeteor> oh okay let me check that out
Jul 01 08:37:03 <demeteor> I cant find something. it show me problem from people not finding their mouse when they plug in their usb -_-
Jul 01 08:37:53 <_av500_> you spent 5 minutes?
Jul 01 08:38:27 <demeteor> yeah I  look more. but what I find si something about dev
Jul 01 08:38:31 <demeteor> udev rules*
Jul 01 08:38:42 <demeteor> sorry accetendal use of the enter key
Jul 01 08:48:34 <demeteor> I would have to remake the hardlink to make my test?
Jul 01 08:54:19 <foertel> hey guys
Jul 01 09:02:01 <demeteor> cant find anything helpfull what I found I must change the wantedby=nameofdevice.something . but really now idea what to add there. trying to find out how to find the name of the usb but cant
Jul 01 09:02:58 <foertel> can you get me up to speed? my retailer said "pre-order" for beaglebone black, but i find blog posts from october 2013 working with it ... is it a new revision? or is it a regional thing?
Jul 01 09:03:14 <demeteor> this is the thing I have changed . : WantedBy=usb0.target
Jul 01 09:05:25 <_av500_> foertel: they are in hot demand
Jul 01 09:05:31 <_av500_> sold out immediately
Jul 01 09:05:41 <_av500_> so best is to find a retailer and order so you get into the queue
Jul 01 09:05:53 <_av500_> dont wait for it to be "in stock"
Jul 01 09:06:21 <jaw221> sparkfun isn't, I just ordered my 2nd from them. turnaround was less than 10 days
Jul 01 09:06:34 <jaw221> if you're in the US, that is
Jul 01 09:06:39 <foertel> i am from germany
Jul 01 09:06:50 <foertel> i just wonder why it was "pre-order", as it was not released yet ...
Jul 01 09:07:00 <foertel> "only available from 1. July"
Jul 01 09:07:18 <_av500_> dont trust retailers
Jul 01 09:07:20 <foertel> can you tell me if the beaglebone black's ARMv8 supports AES_IN?
Jul 01 09:07:52 <foertel> ha ha ... nice ... conrad tells me "will be delivered in 27 weeks"
Jul 01 09:08:25 <_av500_> AES_IN?
Jul 01 09:09:01 <_av500_> http://www.amazon.de/BeagleBone-Beagleboard-Black-Cortex-Speicher/dp/B00CO3MZCW
Jul 01 09:09:28 <_av500_> http://geizhals.de/beaglebone-black-bb-bblk-000-a944454.html
Jul 01 09:10:32 <foertel> yeah, aes extended instruction set ... hardware support for encryption
Jul 01 09:11:47 <_av500_> not that I know off
Jul 01 09:12:10 <foertel> is there some proc/cpuinfo out there?
Jul 01 09:14:21 <KotH> foertel: AES_NI is an intel thing. the BBB does not have an intel cpu
Jul 01 09:15:03 <KotH> foertel: there might be other accelerators though (AES accelerators have been comon in the uC/embedded world for 10 years or more)
Jul 01 09:15:30 <foertel> mh, AES_IN is in intel, amd, arm, sparc, etc :)
Jul 01 09:16:03 <foertel> https://en.wikipedia.org/wiki/AES_instruction_set#Supporting_CPUs
Jul 01 09:16:44 <foertel> "The ARMv8-A processor architecture, announced in 2011, will also have user level instructions which implement AES rounds."
Jul 01 09:16:51 <_av500_> v8
Jul 01 09:16:54 <_av500_> BBB is v7
Jul 01 09:17:23 <foertel> arrr ... damn ;) It's *A*8 ... but *v*7
Jul 01 09:17:25 <foertel> i am sorry
Jul 01 09:18:15 <_av500_> well, there is also A7 from apple and A7 from ARM :)
Jul 01 09:18:20 <_av500_> and an A7 in south Germany
Jul 01 09:18:33 <_av500_> anda gate in FRA
Jul 01 09:19:06 <jannau> A7 is in north germany too
Jul 01 09:19:27 <foertel> :p
Jul 01 09:19:28 <jannau> and there is a A80 from allwinner
Jul 01 09:19:39 * vvu votes with Audi A7
Jul 01 09:21:21 <_av500_> +1
Jul 01 09:31:01 <_av500_> so you can use an armv7 bases A7 in your A7 driving on the A7 to gate A7
Jul 01 09:32:23 <vvu> A7cepion
Jul 01 09:32:24 <demeteor> pff dced. amm one offtopc question does bbb have umbundu image ?
Jul 01 09:32:39 <demeteor> or only armstrong and debian ?
Jul 01 09:35:10 <_av500_> yes, there are some from 3rd parties
Jul 01 09:35:20 <_av500_> going forward, debian is the supported one
Jul 01 09:35:28 <_av500_> of course you can put anything you like
Jul 01 09:36:41 <jannau> or you can use an armv8 based A7 in your A7 driving on the A7 to gate A7
Jul 01 09:37:00 <demeteor> is it suggested to use 3rd partie ones or better use debian one ?
Jul 01 10:02:59 <socrat> can anybody help trace crash in .so file, i have backtrace
Jul 01 10:03:25 <_av500_> pastebin it
Jul 01 10:09:51 <_av500_> also, use pastebin
Jul 01 10:10:56 <_av500_> socrat: 1) stop PM'in me
Jul 01 10:11:18 <_av500_> 2) if there is anything you dont understand, google it
Jul 01 10:11:25 <socrat> ok
Jul 01 10:11:25 <_av500_> enter pastebin in google
Jul 01 10:17:16 <socrat> can anybody help me trace this crash http://pastebin.com/RtE1AnTM
Jul 01 10:20:47 <socrat> can anybody help me trace this crash http://pastebin.com/RtE1AnTM
Jul 01 10:23:38 <_av500_> no
Jul 01 10:23:44 <_av500_> its android
Jul 01 10:23:53 <_av500_> there are Android tools to do that
Jul 01 10:23:57 <_av500_> but this is the wrong channel
Jul 01 10:24:02 <_av500_> see #android
Jul 01 10:24:12 <_av500_> and go from there
Jul 01 10:24:22 <_av500_> there are android google groups
Jul 01 10:24:26 <_av500_> stackoverflow
Jul 01 10:24:28 <_av500_> etc..
Jul 01 10:38:32 <das> what was the rationale of the switch form Angstrom to DEbian ? (I wasn't very active this year)
Jul 01 10:38:47 <_av500_> support
Jul 01 10:39:50 <das> is it correlated to the influx of newbies on BB ?
Jul 01 10:40:02 <tbr> no
Jul 01 10:40:05 <_av500_> more to the outflux of angstrom supporters
Jul 01 10:40:44 <das> ok, ty ... all for the better IMO
Jul 01 11:10:12 <epsi> i am new to beaglebone...
Jul 01 11:10:45 <epsi> i would like to connect my touchLCD with beaglebone...how sholud i connect?
Jul 01 11:10:55 <epsi> any proper documentation is there?
Jul 01 11:11:06 <tbr> follow the instructions from the vendor of your LCD
Jul 01 11:42:12 <carbonizer> hello everybody
Jul 01 11:44:10 <KotH> greetings carbonizer. how may we abuse you today?
Jul 01 11:44:23 <woglinde> hi koth
Jul 01 11:44:33 <KotH> hoi woglinde
Jul 01 11:44:36 <carbonizer> is there a way to enable command line history in uboot, or is it enabled and am I doing something wrong (from a serial connection, the up arrow is just moving the cursor up)?
Jul 01 11:44:37 <KotH> woglinde: was macht die kunst?
Jul 01 11:44:54 <KotH> carbonizer: have you checked the uboot documentation?
Jul 01 11:45:31 <KotH> but a history is not something i'd expect in uboot.. it's just a "simple" bootloader, after all
Jul 01 11:45:45 <carbonizer> the only thing I'm finding is a reference to a compiler define that seems to have been added several versions ago
Jul 01 11:46:05 <KotH> that is your answer then
Jul 01 11:46:59 <carbonizer> you mean, you think that the uboot I'm working with was not compiled with the history option set?
Jul 01 11:47:25 <KotH> yes
Jul 01 11:48:20 <carbonizer> I agree that I wouldn't have been surprised if there was no history, but I keep finding uboot tutorials that seem to indicate it exists
Jul 01 11:49:17 <carbonizer> I should be able to find the code on the beaglebone git and check, right?
Jul 01 11:49:49 <KotH> where ever you have your binaries from
Jul 01 11:49:59 * KotH usually compiles a complete system from scratch using buildroot
Jul 01 11:50:07 <KotH> then i have everything under controll
Jul 01 11:50:35 <carbonizer> right now, it is just the system that shipped with the board
Jul 01 11:56:09 <woglinde> readline support
Jul 01 12:32:24 <_av500_> carbonizer: mainline uboot is fine for BBB
Jul 01 13:17:24 <abferm_> Is anyone having vbus issues on kernels 3.8, 3.12, and 3.14?
Jul 01 13:20:25 <woglinde> abferm_ aksing it frequently here does not help you
Jul 01 13:23:59 <thurgood> given the lack of response.. I would have to assume that no one else is experiencing it :/
Jul 01 13:26:46 <abferm_> I've seen a couple forum posts on the subject, but there are never any responses.
Jul 01 13:30:40 <abferm_> I beleive it has something to do with the USB power capacitor. From what I've read it is about20uf below the recomended value. I even have some scope readings from the bus. There are some nasty voltage spikes when I boot with an offending device connected.
Jul 01 13:43:02 <thurgood> ah, so it's a specific device doing it?
Jul 01 13:44:31 <KotH> abferm_: maybe it would be a good idea to tell _WHAT_ problems you experience
Jul 01 13:44:50 <KotH> (no, i'm not going to search my logs)
Jul 01 13:49:07 <jkridner> may: http://stackoverflow.com/questions/13385690/how-to-use-git-with-gnome-keyring-integration
Jul 01 13:59:16 <Ventura> Hi everyone. I am trying to use the last version (0.8.0) of openocd with beaglebone but for any reason the initialization fail. Anybody had already success using openocd with beaglebone ???
Jul 01 13:59:32 <abferm_> I see the problem with about half of the USB devices I've tried. The error only happens when booting with one of these devices, and the USB bus is disabled for the entire session if it happens.
Jul 01 14:00:03 <BennyB_> hi, having problems on boot with BBB it tells me this: (kernel 3.8)  net eth0: phy 4a101000.mdio:01 not found on slave 1
Jul 01 14:01:28 <Ventura> I barely remember that it worked in the past...
Jul 01 14:02:59 <BennyB_> yes I do so, i compiled different kernels 3.12, 3.8, 3.14, switched now back to latest 3.8 and now I do get this message. should I care? It seems networking is wirking
Jul 01 14:03:15 <BennyB_> ...working
Jul 01 14:05:41 <BennyB_> I also think the output on serial debug console is much less. I even looked into /etc/inittab for the getty ttyO0 , but it is there
Jul 01 14:07:09 <BennyB_> that is the complete output from serial console: http://pastebin.com/9qjnnta0
Jul 01 14:07:37 <BennyB_> I've seen much more in the past. what is wrong with my bbb?
Jul 01 14:11:26 <abferm_> KotH this is the error I'm seeing [    0.755202] musb-hdrc musb-hdrc.1.auto: VBUS_ERROR in a_wait_vrise (99, VALID), retry #3, port1 00000100
Jul 01 14:18:47 <BennyB_> demsg gives me this output: libphy: 4a101000.mdio:00 - Link is Up - 100/Full
Jul 01 14:19:13 <KotH> abferm_: sounds nasty
Jul 01 14:19:28 <KotH> abferm_: what does the approriate kernel mailinglist have to say about it?
Jul 01 14:19:38 <KotH> abferm_: as it sounds like a bug in musb
Jul 01 14:19:46 <_av500_> a bug in musb?
Jul 01 14:19:48 <_av500_> unheard of
Jul 01 14:19:54 <thurgood> lol
Jul 01 14:20:08 <BennyB_> strange.... first it complains not finding " libphy: PHY 4a101000.mdio:01 not found" but then it loads
Jul 01 14:20:12 <KotH> Ventura: what do you need openocd for?
Jul 01 14:20:17 <KotH> Ventura: are you debugging the kernel?
Jul 01 14:22:42 <KotH> BennyB_: could be because of the pin conflicts with the cape
Jul 01 14:22:55 <KotH> BennyB_: unplug the cape and try again
Jul 01 14:24:09 <BennyB_> Koth: i have no cape plugged but copied w1_00A0.dtbo (compiled on bbb) to /lib/firmware
Jul 01 14:25:09 <KotH> BennyB_: you have a conflict, find out where it comes from
Jul 01 14:25:20 <KotH> BennyB_: at least the kernel reports one
Jul 01 14:25:24 <KotH> BennyB_: that by itself is fishy
Jul 01 14:25:25 <BennyB_> Koth: I deleted the file and did a reboot, no change, same output
Jul 01 14:29:39 <BennyB_> KotH: where can I start to look for the error? It reports BB-BONELT-HDMIN conflict P8.45 ...  Nothing is connected to bbb besides the serial debug cord
Jul 01 14:29:59 <KotH> capemgr does detect something
Jul 01 14:30:00 <KotH> look there
Jul 01 14:30:05 <KotH> dunno about it, have never used it
Jul 01 14:30:26 <KotH> if you ask nicely, maybe _av500_ may help you with a link to google
Jul 01 14:30:34 <BennyB_> KotH: my Uenv.txt is from robertcnelsons eewiki guide
Jul 01 14:30:55 <KotH> BennyB_: step #1: understand what you kanged
Jul 01 14:31:08 <KotH> BennyB_: step #2: modify it to your needs
Jul 01 14:31:34 <KotH> BennyB_: step #3: do step #2 properly so that it doesnt let out the magic smoke
Jul 01 14:32:07 <thurgood> pastebin your uEnv.txt perhaps?
Jul 01 14:32:16 <BennyB_> KotH: sure. I'll try my very best.
Jul 01 14:33:02 <BennyB_> KotH: uenv.txt : http://pastebin.com/dv3FpJCu
Jul 01 14:34:01 <KotH> BennyB_: as i said, i never worked with capemgr, so i cannot help you there
Jul 01 14:34:22 <KotH> BennyB_: but it looks like you have either some conflicts in your DT, a cape gets misdetected, or something similar
Jul 01 14:34:32 <BennyB_> KotH: ok, anyone else here with experience in capemgr?
Jul 01 14:34:39 * KotH points at panto
Jul 01 14:34:48 <BennyB_> *g*
Jul 01 14:35:04 <KotH> er hat's verbrochen ;)
Jul 01 14:36:51 <BennyB_> verbrochen ist gut *g*
Jul 01 14:39:05 <BennyB_> the strange thing is that I 100% folloed the howto three times. for 3 different kernels. but now back on current 3.8 (.13 i think) something is wrong with my bone
Jul 01 14:39:47 * panto hides 
Jul 01 14:40:32 <thurgood> does everything function?
Jul 01 14:40:58 <tbr> the kernel is done, so everything works, by definition. *snerk*
Jul 01 14:41:00 <mike29> Hey Guys, Im new to electronics,, very new. Im studying AeroNautical & Mechanical ENG at uni and am keen to get  into electronics, I want to be able to design my own circuits, think hey, I want to design a 3d printer controller and spend a few months doing so, but where do i start in circuit design?
Jul 01 14:41:03 <BennyB_> not everything, my onewire sensor does not work, it's not detected
Jul 01 14:41:14 <KotH> mike29: step #1 learn german
Jul 01 14:41:31 <KotH> mike29: step #2 buy tietze&schenk halbleiterschaltungstechnik
Jul 01 14:41:57 <_av500_> #4 profit
Jul 01 14:42:05 <BennyB_> i installed owfs, seems to work, the owfs website is working, but no sensor detected
Jul 01 14:42:34 <KotH> mike29: the circuit designers companion by wilson is also recommended
Jul 01 14:43:23 <KotH> mike29: stay away from "the art of electronics", lots of circuits with no explanation which ones are good an which ones are not (yes, there are bad circuits in the book as well)
Jul 01 14:44:15 <BennyB_> is ther any advanced howto for the w1 driver? I've googled alot but not finding explanations for the onewire
Jul 01 14:44:40 <mike29> Thanks, Im very curious on how to get things working...blibking an LED doesnt float my boat really haha,  Why do I need a processor there, tdoes that need a resisot? that kinda thing...make a fully working board. Im big on 3D Robitics APM and would also like to be able to build my own RC autopilot
Jul 01 14:45:14 <KotH> mike29: oh.. lots of questions then
Jul 01 14:45:40 <KotH> mike29: please keep in mind that electronics design is an art, a craft. you cannot learn it from theory (alone)
Jul 01 14:45:57 <KotH> mike29: there are a couple of books that tell you bits and pieces, but in the end you have to try it yourself
Jul 01 14:46:07 <KotH> mike29: also note, that there is a damn lot of cargo cult out there
Jul 01 14:46:23 <KotH> mike29: few of those who call them selves engineers actually know what they are doing
Jul 01 14:47:08 <KotH> mike29: i also recommend you to get one of the kosmos electronic kits, if they are available in the uk
Jul 01 14:47:11 <KotH> mike29: or anything similar
Jul 01 14:47:12 <mike29> Yeah haha, Im up for  learning it all... Im just looking for a cool hobby that i can do in my uni halls, Cant take my UAVs to uni :L
Jul 01 14:47:17 <KotH> mike29: those stuff really teach how things work :)
Jul 01 14:48:06 <_av500_> a breadboard and some parts will get you very far
Jul 01 14:48:20 <_av500_> im sure there is a ton of free books/courses online
Jul 01 14:48:32 <_av500_> just start somewhere
Jul 01 14:51:10 <KotH> _av500_: see comment about kosmos :)
Jul 01 14:53:15 <_av500_> https://www.google.com/search?q=electronics+starter+kit
Jul 01 14:55:39 <abferm_> KotH I haven't looked into the mailinglists, but I believe it is more a hardware issue, as the devices work more frequently with an extender cable(I assume it is adding a small amount of capacitance). I see a slightly better readout on my scope with the extender as well.
Jul 01 14:57:06 <BennyB_> panto: when are you online? I have to leave soon, can I ask you something about the capemgr tomorrow?
Jul 01 14:58:03 <KotH> abferm_: if they work with a cable, then it's rather that the cable adds inductance
Jul 01 14:58:10 <KotH> abferm_: ie the device is drawing too much power
Jul 01 14:58:17 <KotH> abferm_: aka too much inrush current
Jul 01 14:58:40 <KotH> BennyB_: he is online unless he is on poop duty
Jul 01 14:59:02 <BennyB_> KotH: lol
Jul 01 16:24:18 <thaytan> I have a problem on my BBB with read timeouts in bash and I have no idea what's going on
Jul 01 16:24:28 <thaytan> with the pre-burnt angstrom image 'read -t 2' is reliable
Jul 01 16:24:47 <thaytan> with an arago image I built myself (same version of bash), it works once and doesn't time out on subsequent calls
Jul 01 16:25:36 <thaytan> same kernel in both cases
Jul 01 17:58:24 <__butch__> Dumb question: Anybody have experience using PWM with either python or ruby?
Jul 01 18:00:47 <VoltVisionSteve> All, has anyone ever implemented a capacitive touch sensor input using only the BBB GPIO or ADC?
Jul 01 18:21:44 <westcost> newbie question on /dev/tty for usb
Jul 01 18:22:13 <westcost> don't see an /dev/ttyUSB0 or /dev/tytUSB1
Jul 01 18:24:14 <westcost> want to write c program to talk to /dev/ttyUSB1
Jul 01 18:24:20 <westcost> thanks in advance
Jul 01 18:26:13 <tbr> westcost: there are good tutorials about writing software in C that talks to a serial TTY
Jul 01 18:27:56 <abferm_> westcost: http://lmgtfy.com/?q=c+linux+serial+communication
Jul 01 18:28:17 <woglinde> tbr yes and it mostly suckz with c
Jul 01 18:28:38 <woglinde> with python it is dream
Jul 01 18:29:28 <westcost> actually, trying to figure out what the /dev/tty device name is for the USB port, most documentation says that is should be /dev/ttyUSB0 /dev.ttyUSB1
Jul 01 18:29:52 <westcost> but on my Beagle, only see
Jul 01 18:30:30 <westcost> tty, tty0.. tty64
Jul 01 18:30:34 <tbr> westcost: what does your setup look like? what are you trying to do in the bigger picture?
Jul 01 18:30:51 <westcost> my bbb is right out of the box
Jul 01 18:30:56 <westcost> thanks in advance
Jul 01 18:32:44 <westcost>  root@beaglebone:/dev# ls tty* tty    tty14  tty20  tty27  tty33  tty4   tty46  tty52  tty59  tty8    ttyS3 tty0   tty15  tty21  tty28  tty34  tty40  tty47  tty53  tty6   tty9 tty1   tty16  tty22  tty29  tty35  tty41  tty48  tty54  tty60  ttyGS0 tty10  tty17  tty23  tty3   tty36  tty42  tty49  tty55  tty61  ttyO0 tty11  tty18  tty24  tty30  tty37  tty43  tty5   tty56  tty62  ttyS0 tty12  tty19  tty25  tty31  tty38  tty44  tty50  tty5
Jul 01 18:33:31 <abferm_> westcost: I think tbr wants to know how things are connected
Jul 01 18:33:52 <tbr> westcost: just what abferm_ says, what is the BIGGER PICTURE
Jul 01 18:34:28 <westcost> nothing has been connected to BBB
Jul 01 18:34:30 <tbr> we are not clairvoyant (at least my crystal ball is out for repair, it keeps showing soccer games)
Jul 01 18:34:44 <westcost> just ptty to console
Jul 01 18:34:46 <westcost> root@beaglebone:/dev# uname -a Linux beaglebone 3.8.13-bone47 #1 SMP Fri Apr 11 01:36:09 UTC 2014 armv7l GNU/Linux
Jul 01 18:34:59 <tbr> so, then the board is obviously OFF, if you have NOTHING connected to it, right?
Jul 01 18:35:16 <westcost> powered up and ptty to console
Jul 01 18:35:27 <tbr> _how_ are you powering the board?
Jul 01 18:35:38 <tbr> _how_ have you "pty to console"?
Jul 01 18:35:48 <abferm_> westcost: ttyUSB* will not show up unless there is a usb serial device, and what tbr said
Jul 01 18:35:50 <westcost> mini usb to windows and ptty
Jul 01 18:36:06 <tbr> I guess you mean PuTTY?
Jul 01 18:36:20 <westcost> yes PuTTY
Jul 01 18:36:28 <westcost> logged in as root
Jul 01 18:36:35 <westcost> and able to talk to shell
Jul 01 18:36:50 <tbr> ok, so, what device do you want to connect over a serial port to the BBB?
Jul 01 18:37:32 <westcost> first want to write c program to open /dev/ttyUSB port and write
Jul 01 18:37:55 <westcost> the device is a lcd with a usb port
Jul 01 18:38:12 <tbr> now we're finally getting closer...
Jul 01 18:38:31 <tbr> please realize that this is the _first_ time you mention the USB-serial port LCD...
Jul 01 18:38:32 <westcost> sorry about that and thanks your patiences
Jul 01 18:38:37 <abferm_> plug the device in and see what it enumerates as
Jul 01 18:38:44 <Vaizki_> well you have to connect the USB LCD first of all :D
Jul 01 18:38:56 <westcost> ok, will try that
Jul 01 18:38:57 <tbr> for bonus points, connect it before you turn on the BBB.
Jul 01 18:38:57 <Vaizki_> and check the last lines of 'dmesg' to see what happened
Jul 01 18:39:03 <Vaizki_> oh, right.
Jul 01 18:39:15 <tbr> as hotplug might not work
Jul 01 18:39:32 <westcost> quick question, what about the current usb port that I'm taking on with putty
Jul 01 18:39:45 <westcost> what is that in /dev/tty*
Jul 01 18:40:03 <Vaizki_> it's not there
Jul 01 18:40:38 <westcost> no, only see /dev/tty*, none with /dev/ttyUSB*
Jul 01 18:40:39 <tbr> it's probably listed as /dev/ttyGS0 or such
Jul 01 18:40:46 <Vaizki_> you are talking to the BBB over SSH over TCP/IP, the usb between the BBB and your computer shows up as a network interface and not as a serial tty
Jul 01 18:40:48 <westcost> ok, that makes sence
Jul 01 18:41:04 <tbr> unless he talks to the virtual COM port
Jul 01 18:41:16 <Vaizki_> or hmm.. ok I might be talking out of my ass because I never even tried Ångström
Jul 01 18:41:28 <tbr> this is probably debian
Jul 01 18:41:32 <Vaizki_> yea it's ttyGS0
Jul 01 18:41:44 <Vaizki_> for the usb gadget serial
Jul 01 18:42:26 <westcost> The usb port just show up as  ttyACM0
Jul 01 18:43:02 <westcost> thanks a bunch

Jul 01 19:52:34 <Fabian_> hi
Jul 01 19:53:09 <Fabian_> I had one question
Jul 01 19:53:29 <Fabian_> my BBB not boot
Jul 01 19:54:13 <Fabian_> My Pc has Debian
Jul 01 19:54:33 <Fabian_> not reconed the USB port
Jul 01 20:01:28 <Kamikazie> So I feel like a total noob but for the life of me I cant get the BBB to do anything via Cloud 9 or the webserver examples. Specifically I am trying to just blink the USR leds. Anyone got a minute to help troubleshoot me being a newb.
Jul 01 20:12:30 <thurgood> kamikaze, might help if you linked to the tutorial you're following and how far you get before you run into trouble
Jul 01 20:17:29 <day> im trying to figure out how to install irssi via opkg on my beaglebone black
Jul 01 20:23:56 <day> are there any thirdparty repositories for opkg/angstrom/beaglebone black with more compiled software?
Jul 01 20:26:30 <_av500_> day install the debian image
Jul 01 20:26:33 <_av500_> and go from there
Jul 01 20:27:04 <day> _av500_: was hoping i could avoid that :D
Jul 01 20:28:16 <day> btw. can i screw the system up to a degree that i need to use the hdmi port to see whats going on? Because i dont have a mini hdmi adapter
Jul 01 20:55:53 <__butch__> Anybody want to talk PWM using ruby or python?
Jul 01 20:57:11 <ds2> don't need more constrictors around here...
Jul 01 21:05:00 <day> how am i supposed to flash the emmc? the getting-started page only suggests the win32 disk imager. which doesnt work for the emmc, does it?
Jul 01 21:09:31 <day> nvm figured it out
Jul 01 21:17:59 <day> can i use a bigger than 2gb micro sd card to flash the board?
Jul 01 21:36:12 <__butch__> An actual PWM question: Using the ruby 'beaglebone' gem, I can enable PWM on P9_14 to flash an LED, but when I turn it off, the LED stays lit (i.e. the pin is high).  Why is that?
Jul 01 21:38:27 <thurgood> day, you can use as big a card as the bbb will support
Jul 01 22:03:21 <day> thurgood: it worked :). *damn that thing is slow* I wasnt sure because i thought that maybe the flash program tries to copy the sd card 1:1
Jul 01 22:07:35 <woglinde> woot kernel becomes bx lr
Jul 01 22:10:47 <_av500_> ?
Jul 01 22:11:05 <woglinde> av500 see the patch from rmk
Jul 01 22:11:52 <woglinde> next goal
Jul 01 22:39:38 <jeremyagost> is it possible to access the eMMC of a BeagleBone Black using the serial interface somehow?
Jul 01 22:39:57 <jeremyagost> I’ve got two BBBs and I’d love to clone the eMMC of one onto the other
Jul 01 22:40:53 <Shadyman> jeremyagost: You could probably use dd to make an image of it if you find the right /dev/ device
Jul 01 22:41:43 <jeremyagost> Shadyman: that would be suitable to get the image
Jul 01 22:41:49 <jeremyagost> but not to flash onto the second device
Jul 01 23:03:28 <shay_shay> heres a related question: if i get locked out for example i disable the root password nd i have no sudoer, normally on a PC i can just chroot to the system and reset the password
Jul 01 23:03:35 <shay_shay> even ona raspberry pi i can do that
Jul 01 23:03:45 <shay_shay> but here the emmc presents a challenge?
Jul 01 23:03:56 <shay_shay> can you mount the emmc from another computer?
Jul 01 23:21:43 <Kamikazie> Anyone have any experience on accelerometers?
Jul 01 23:22:43 <ds2> ddX/(dt)^2
Jul 01 23:31:19 <vagrantc> shay_shay: i don't see what's different about the eMMC in that case... youjust have to mess around with bootargs
Jul 01 23:31:39 <vagrantc> shay_shay: init=/bin/bash is a useful trick.
Jul 01 23:38:58 <shay_shay> vagrantc: you mean you can plug the emmc into another computer and chroot it?
Jul 01 23:39:15 <vagrantc> ah, yes, that's different.
Jul 01 23:39:32 <vagrantc> shay_shay: no, i meant booting the BBB from the BBB with different boot arguments
Jul 01 23:40:05 <shay_shay> can you boot up another OS the bbb from usb and then read the emmc?
Jul 01 23:40:05 <vagrantc> shay_shay: and then setting a root password or adding your user to sudoers or what have you
Jul 01 23:40:39 <vagrantc> or from microSD, not sure if the u-boot supports USB booting.
Jul 01 23:40:48 <shay_shay> ok from microsd
Jul 01 23:40:59 <shay_shay> as long as i can boot another system then its fine
Jul 01 23:41:12 <vagrantc> as long as the OS you're booting supports the eMMC...
Jul 01 23:41:18 <shay_shay> where would you put init=/bin/bash?
Jul 01 23:42:12 <vagrantc> either edit uEnv.txt on the fat partition, or drop a uEnv.txt on the microSD card, and edit the bootargs= line
Jul 01 23:42:53 <shay_shay> uEnv.txt on the sdcard can be made to boot to emmc?
Jul 01 23:43:00 <vagrantc> yes.
Jul 01 23:43:07 <shay_shay> ok that makes sense
Jul 01 23:43:21 <vagrantc> it's just a bunch of environment variables
Jul 01 23:43:55 <vagrantc> and the eMMC essentially looks to u-boot and linux pretty much like any other SD card.
Jul 01 23:48:43 <shay_shay> maybe i'll make my own irc client with blessed and twisted python modules
Jul 02 00:11:50 <nope3000> Hey, just unboxed my beaglebone black... And it's amazing!! Just have a really stupid question though.
Jul 02 00:11:57 <shay_shay> ya
Jul 02 00:12:06 <nope3000> How is it able to ssh through usb?
Jul 02 00:12:06 <shay_shay> if i can answer it i will
Jul 02 00:12:16 <nope3000> Like I know the command
Jul 02 00:13:08 <day> nope3000: i just finished flashing mine, what do you need to know? :)
Jul 02 00:13:19 <nope3000> But how does it do it? The reason I ask is because I'm thinking about switching to ArchLinux because I have been using it for years now, but I really like being able to ssh via usb
Jul 02 00:13:41 <shay_shay> you can do it on arch
Jul 02 00:13:51 <shay_shay> are you asking how to set it up on arch like that?
Jul 02 00:14:07 <day> isnt it just a driver thing? its basically simulating a tcp connection via usb?
Jul 02 00:14:12 <nope3000> Yep! Is it like a service?
Jul 02 00:14:30 <nope3000> How did they emulate a network adapter on top of a usb?
Jul 02 00:14:42 <day> i imagined it like a usb to rs232 emulator :/
Jul 02 00:14:47 <H-H-H> ssh over usb works fine in arch
Jul 02 00:14:48 <shay_shay> http://archlinuxarm.org/forum/viewtopic.php?f=48&t=5504
Jul 02 00:15:54 <shay_shay> https://developer.ridgerun.com/wiki/index.php/How_to_use_USB_device_networking
Jul 02 00:16:23 <day> may i ask why you want to use usb->ethernet? why not just plug it into your switch :?
Jul 02 00:16:34 <shay_shay> less wires
Jul 02 00:16:57 * day is way past that point xD
Jul 02 00:17:12 <H-H-H> btw i read somewhere that if the bb is run on usb it throttles the cpu due to under current
Jul 02 00:17:53 <shay_shay> yep
Jul 02 00:18:21 <H-H-H> thats why i run mine on a 5v 3amp supply
Jul 02 00:18:23 <nope3000> Thanks so much! I just needed to be pointed in the right direction. And I sadly only have a router that is far away, plus I want to be able to bring this to work. But my job has a very strict network.
Jul 02 00:18:35 <shay_shay> thank god for google
Jul 02 00:19:00 <day> shay_shay: does it only throttle if there isnt enough current available? Or usb power = throttled?
Jul 02 00:19:02 <nope3000> Lol I have been googling the wrong thing for a good 10 minutes
Jul 02 00:19:20 <H-H-H> afaik usb+throttled
Jul 02 00:19:34 <day> good to know
Jul 02 00:19:36 <H-H-H> err i mean usb = throttled
Jul 02 00:19:43 <shay_shay> day: no idea, havnt tested that. i have a powered usb hub so maybe i can do some unscientific tests
Jul 02 00:20:07 <day> im using it with an 1A capable usb power wall brick thats why im asking
Jul 02 00:20:10 <shay_shay> if i have a voltimeter i could make them official
Jul 02 00:21:04 <shay_shay> day: well i think a lot of people use those with a 5.5mm barrel jack adapter
Jul 02 00:21:15 <shay_shay> but yeah maybe it depends on the current
Jul 02 00:22:36 <shay_shay> or
Jul 02 00:24:01 <Jonnyw2k> I think it is software based, it know which port is being used
Jul 02 00:24:13 <day> cpufreq-info says cpufreq stats: 300 MHz:99.01%, 600 MHz:0.09%, 800 MHz:0.02%, 1000 MHz:0.88%  (93)
Jul 02 00:25:18 <Jonnyw2k> "It is not in the BBB manual because that is a fact. You can run at 1GHZ on USB, as long as you do not over load it with a bunch of stuff in the USB host or try to insert a cape"
Jul 02 00:25:31 <Jonnyw2k> BBB deploys DVFS that allows the frequency to flow from 300MHZ to 1GHZ as needed. It idles at 300MHZ in Angstrom, until you give it something to do, then it can pop up to 1GHz.
Jul 02 00:28:29 <H-H-H> i just read a google groups convo stating that a;; bbb,s shipped were upped from the 500ma to 1300ma linit in the pmic however it doesnt apply if your usb port on your pc only allows 500ma lol
