**** BEGIN LOGGING AT Sat Jul 13 02:59:58 2013 Jul 13 03:03:22 ? I am not doing this for homework. Why? Jul 13 03:05:35 so how would I go about changing the P8 pin 3 to mode 7 on the new 3.8 kernel? I have been googling for over an hour and so far can only get Python code and how to do it on BBW Jul 13 03:06:05 mrpackethead: +1 Jul 13 03:12:25 mrpackethead, do you know the window issue with OpenCV and BBB? Jul 13 03:18:53 szhao: What class are you in? Jul 13 03:51:10 jmoyerman: I am doing this for a design challenge. This window issue is kind of annoying Jul 13 03:53:52 szhao: opencv and beagle is the #1 source of questions for #beagle. Mostly students who have been given assignments to do Jul 13 04:13:52 I guess no one told SeeMitchPlay that having the ability to change pinmux without recompiling the kernel is a good thing ? Jul 13 06:52:13 blah its so quiet Jul 13 06:54:50 head down, working Jul 13 06:59:21 Hi. Jul 13 07:07:15 Right so where was I ? Ah yes I have a conf file for my wpa2 network: http://pastie.org/8136898, however running WPA_Supplicant with the file as it's -c arg doesn't work. I get this error: http://pastie.org/8136901. After some googling I have found reason 3 means Deauthenticated because sending station is leaving (or has left) IBSS or Jul 13 07:07:20 ESS Jul 13 07:08:07 I have a RTL1817L based USB wifi dongle, for which the drivers are installed. Jul 13 07:08:32 Can anyone help? Jul 13 07:16:14 ka6sox: anythign interesting? Jul 13 07:45:25 No? Jul 13 07:45:44 OK Jul 13 07:49:40 no what? Jul 13 08:09:10 Help Jul 13 08:24:20 Right so where was I ? Ah yes I have a conf file for my wpa2 network: http://pastie.org/8136898, however running WPA_Supplicant with the file as it's -c arg doesn't work. I get this error: http://pastie.org/8136901. After some googling I have found reason 3 means Deauthenticated because sending station is leaving (or has left) IBSS or ESS Jul 13 08:24:26 Can anyone help? Jul 13 08:26:58 Hello! Jul 13 08:27:24 I am a newbie trying to build the android AOSP jellybean source for my beagle board and required some guidance. Jul 13 08:28:29 * emocakes is listening to "Dancing With Myself" by Billy Idol, from the album Billy Idol. 251kbps MP3 Jul 13 08:55:29 i wish everyone a weird saturday morning! http://www.youtube.com/watch?v=f2doyCL7Ogc Jul 13 08:57:02 KotH: ............... Jul 13 08:57:49 wtf nxp srsly Jul 13 09:02:36 Anyone around who can help? Jul 13 09:02:49 Willdude123: you are asking in the wrong channel Jul 13 09:03:09 Willdude123: this is not exactly beagle related, thus very little knowledge on wpa is available Jul 13 09:03:24 Oh but it's on my BBB. Jul 13 09:03:31 Willdude123: beside... it's fucking saturday morning! people are either drunk or still asleep Jul 13 09:03:59 because something runs on bbb doesnt mean it's related to the bbb Jul 13 09:04:39 or would you say that running ms office on a linux system would qualify you for asking about formating problems on the linux kernel mailinglist? Jul 13 09:05:07 Depends. Jul 13 09:05:24 no, it doesnt depend Jul 13 09:05:36 it would be plain wrong Jul 13 09:05:47 If the formatting problem would not exist on windows, maybe. Jul 13 09:05:58 it would still not be a linux kernel problem Jul 13 09:06:09 And nobody in ##linux has heard of angstrom. Jul 13 09:06:30 it's also not an angström problem Jul 13 09:06:34 it's a wpa suplicant problem Jul 13 09:13:40 KotH: are you sure it's not related to specific driver (either for USB core or for wifi adapter) making wpa supplicant work incorrectly? (as in, not sending/receiving certain packets or something) Jul 13 09:14:26 kfoltman: very unlikely Jul 13 09:14:34 KotH: I've had chipset-specific bugs with user-space software (specifically, libusb-based software not working on rk3066 based devices) Jul 13 09:15:16 *sigh* Jul 13 09:15:18 well, SoC-specific Jul 13 09:15:35 we are not talking about something libusb based Jul 13 09:15:38 it's a kernel driver Jul 13 09:15:46 the kernel is very robust on change of hardware Jul 13 09:16:03 either the driver is buggy in general or it's a config error Jul 13 09:16:12 i rather tempt to go for the config error unless proven otherwise Jul 13 09:16:19 well, the kernel I got with BBB wasn't very robust, it oopsed on every device disconnection ;) Jul 13 09:16:57 the later versions were much better though Jul 13 09:33:37 *sigh* Jul 13 09:39:30 KotH: can you help me with a relevant question Jul 13 09:40:00 KotH: shall i order 70% cocoa, or 50%? Jul 13 09:40:27 50%? :O Jul 13 09:41:03 mrpackethead: that depends on your taste Jul 13 09:41:13 mrpackethead: and on the quality of the chocolate Jul 13 09:41:22 since when does #beagle ever worry about on topic Jul 13 09:41:30 50% is much more forgiving on mistakes in the receip than 70% Jul 13 09:41:54 mrpackethead: chocolate is on topic though Jul 13 09:41:55 #beagle was born to be off topic Jul 13 09:42:34 Willdude123: i agree no one other than a few beagleheads knows about angstrum Jul 13 09:45:01 .o0(http://26-26-54.hardwarebug.org/22) Jul 13 09:49:40 KotH: don't suppose you have that Orcad handy? Jul 13 09:51:52 i have an 20y old version in the back room, why? Jul 13 09:52:10 ahh Jul 13 09:52:18 maybe thats not goign to cut it Jul 13 09:52:20 :-) Jul 13 09:52:57 well, it might be worth a try ;-) Jul 13 09:53:19 i just need to find a floppy drive first Jul 13 09:53:34 i'm getting the impression that i'm going to recreate from scratch Jul 13 09:53:49 what do you want to do? Jul 13 09:54:14 kfoltman: fancy a drink some time today? Jul 13 09:54:14 make a beagle-cloned-thingy Jul 13 09:54:31 hmm... Jul 13 09:54:35 what software? Jul 13 09:54:36 i want to merge down a stack of capes into a single pcb Jul 13 09:55:03 remove the stuff i dont' need Jul 13 09:55:18 do what TI wanted me to do . Jul 13 09:55:19 :-) Jul 13 09:55:42 sounds like you have some drug abuse problems Jul 13 09:55:47 ;) Jul 13 09:56:05 what software are you workign with? eagle? Jul 13 09:56:22 yes, currently Jul 13 09:56:26 gee.. Jul 13 09:56:28 boy! Jul 13 09:56:32 though, i'm considering that we need to change Jul 13 09:56:37 get yourself a better software Jul 13 09:56:44 it will save you hours if not days! Jul 13 09:57:22 eagle has been a faithful and useful product to date Jul 13 09:57:30 yes, has been Jul 13 09:57:36 but; Jul 13 09:57:42 but it is severly limited compared to the real stuff Jul 13 09:57:48 its showing its weekness's. Jul 13 09:57:57 the price was right too Jul 13 09:57:58 :-) Jul 13 09:58:16 which was an issue when i started out Jul 13 09:58:21 i guestimate that 2-3 designs of the complexity of a bbb and you will have amortisized the price of the software Jul 13 09:59:38 yes. quite likely Jul 13 09:59:47 and it doesnt do team desing well either Jul 13 10:00:40 i'd liek something that will run natively on mac/linux/windows Jul 13 10:01:02 the only one i know that does that is the cr-5000/cr-8000 Jul 13 10:01:18 but these cost a fortune (100k single seat floating) Jul 13 10:01:26 (iirc) Jul 13 10:01:34 and eagle Jul 13 10:02:43 hmm... orcad does too Jul 13 10:03:02 mm, really Jul 13 10:03:24 according to http://en.wikipedia.org/wiki/Comparison_of_EDA_software#Comparison_of_EDA_packages Jul 13 10:05:02 <_av500_> hmm, no PCAD Jul 13 10:05:08 <_av500_> thats what they use at work I think Jul 13 10:05:33 <_av500_> ah, killed for altium Jul 13 10:05:52 juup Jul 13 10:06:14 and altium is getting more and more expensive since they have a new ceo Jul 13 10:07:35 yup. Jul 13 10:08:07 * KotH wonders how much work it would be to write a half decent cad package from scratch Jul 13 10:08:24 years. Jul 13 10:08:36 yeah.. Jul 13 10:10:34 no pricing Jul 13 10:15:54 the demo version is limited to 75 nets Jul 13 10:15:58 lol. Jul 13 10:16:10 thats less than the power supply Jul 13 10:26:30 mru: sorry, I'm too much of a drooling idiot at the moment :) Jul 13 10:32:21 writing code is OK, but social interactions are probably best avoided Jul 13 10:32:33 kfoltman: ok Jul 13 10:34:12 KotH: why not start with, say, kicad? apart from using a crappy UI library, it can't be ALL bad? Jul 13 10:34:49 and it's not like wxwidgets is going to make or break the project Jul 13 10:38:05 Is wifi easier to set up in the gui? Jul 13 10:39:03 Willdude123: depends on your level of knowledge Jul 13 10:39:31 Cause it's hell to setup without one. Jul 13 10:41:07 Will this work with the 'black? http://www.ebay.co.uk/itm/Versus-Touchpad-7-Tablet-5V-2A-UK-Mains-AC-DC-Adaptor-Charger-Power-Supply-/160966960520?pt=UK_iPad_Tablet_Chargers_Sync_Cables&hash=item257a60e588#shId Jul 13 10:42:39 kfoltman: because kicad has a couple of design mistakes in the lower levels... and the UI design is like.. OMG WE CLONED EAGLE...POORLY Jul 13 10:43:08 KotH: what mistakes, apart from (I suspect) poor handling of mixed units Jul 13 10:43:31 kfoltman: have you ever done some larger electronics projects? Jul 13 10:43:36 KotH: no Jul 13 10:43:48 hmm.. then it will be more difficult to explain Jul 13 10:44:06 well, just try if it's not too much work, I might or might not be able to understand anyway Jul 13 10:44:30 but I've seen bad designs refactored into good designs in my life, it wasn't easy or quick, but it happened Jul 13 10:44:52 let me try it that way: kicad assumes you are drawing on paper, ever little operation involves many mouse clicks and/or key presses Jul 13 10:45:10 right, sometimes it's annoying Jul 13 10:45:22 there is hardly to no automation of the common tasks, like nobody ever took the time to figure out what you do when using an eda package Jul 13 10:45:50 but if the API to manipulate the schematic/pcb is cleaned up and exposed to, say, python scripts, it can be remedied? Jul 13 10:46:23 the orcad i used in highschool.. which was already a couple of years old back then, has done that right. and i really wonder whehter the kicad guys took the time to have a look at real eda tools (even geda!) before doing their ui Jul 13 10:46:33 python does not help Jul 13 10:46:40 it's not a matter of programming language Jul 13 10:46:43 it's a matter of design Jul 13 10:46:52 I recall orcad (pirated, well it was Poland :) ) annoying the hell out of me in my high school days Jul 13 10:47:13 well.. i had the full manuals Jul 13 10:47:15 maybe that helped Jul 13 10:47:38 but, I mean, if you can write a small script to generate you say, 8 op-amps in buffer configuration, together with net labels, it'd already be a kind of progress comparing to what's there now Jul 13 10:48:14 uhmm.. that's not the issue Jul 13 10:48:21 you dont "place 8 opamps" Jul 13 10:48:31 you have a design in your brain, you want to get that down Jul 13 10:48:57 yes, so you don't want to spend too much time switching tools etc. I suppose Jul 13 10:49:14 "i have an opamp here, of maybe type X from manufacturer Y, probably in case Z, i connecti it to a couple of resisotors and a transistor" Jul 13 10:49:34 that's the usual workflow of doing schematic entry Jul 13 10:49:40 kicad does not support this well Jul 13 10:50:53 gschem is better in that, actually geda is supperior in most regards to kicad. but geda has a very loose integration of the different tools, making efficient working in complex designs impossible Jul 13 10:51:29 hmm, how so, place components (assuming they're in the library, and they're usually not), place wires - sure, wire entry is annoying at times, but that could be improved without rewriting everything Jul 13 10:52:06 yes Jul 13 10:52:10 probably Jul 13 10:52:15 I don't know what's their representation of wires, it feels broken to me Jul 13 10:52:28 as in, operations like drag/grab often do something totally unexpected Jul 13 10:52:32 but geting substantial changes into a project that is already far is quite difficult Jul 13 10:52:45 especially if you are not a core member already Jul 13 10:53:01 well, that's mostly a social problem, not a technical one Jul 13 10:53:23 yes, but writing oss is always a social problem, and very little technical Jul 13 10:53:34 I'm not saying that it's easy (social problems are usually harder to solve than technical ones), but I wouldn't write it off totally Jul 13 11:01:12 How do I set the date on my beaglebone? Jul 13 11:01:19 Also, how do I set up wifi? Jul 13 11:01:37 Ah shit Jul 13 11:01:39 Shitty Jul 13 11:02:09 Shit shit. Dammit. The beaglebone gui only detects oh, it's not plugged in. Jul 13 11:05:09 Willdude123: keep in mind that it doesn't have a battery for the RTC, so the clock setting is gone when you switch the power off (not sure if it's also lost on reboot) Jul 13 11:05:24 shouldn't be but I recall something like that happening Jul 13 11:10:01 KotH: installed gschem, just out of curiosity, mixed feelings so far Jul 13 11:12:29 How can I connect to it over ssh without it being plugged in? Jul 13 11:13:17 haha Jul 13 11:13:32 I connected to my bbb over VNC, took under a minute to get wifi working. Jul 13 11:17:04 I accidentally deleted the time panel thing. Jul 13 11:17:08 How do I get it back> Jul 13 11:18:57 click undo Jul 13 11:18:58 ? Jul 13 11:19:24 greetings all Jul 13 11:19:53 Where? Jul 13 11:22:17 Willdude123: have you still got the box that your BBB came in? Jul 13 11:23:21 having trouble with your bbb? Jul 13 11:23:48 no, its having trouble with him. Jul 13 11:23:58 poor BBB Jul 13 11:24:08 heheh Jul 13 11:24:12 my bbb is working great Jul 13 11:24:27 I'm ssh'ed in typing through it now :) Jul 13 11:24:43 makes a great small experimental server Jul 13 11:24:46 mrpackethead: I think so yeah. I fixed that btw. Jul 13 11:25:07 Willdude123: cool. i can fix all your problems with the box it came in. Jul 13 11:25:21 RTFM I'm guessing. Jul 13 11:25:50 Hey.. any of you that are running bbbs.. have you noticed better speed with a good sd card or a usb attached ssd? Jul 13 11:25:52 its amazing those folks at CCO have designed such an amazing problem solving box Jul 13 11:26:01 (assuming anyone has tried this config) Jul 13 11:26:06 Get to the point. Jul 13 11:26:27 Willdude123: put your BBB back in the box Jul 13 11:26:30 tape up the box Jul 13 11:26:31 No Jul 13 11:26:33 and send it iback Jul 13 11:26:44 Willdude123: seriously.. whats wrong> Jul 13 11:26:46 er ? Jul 13 11:27:00 It's fine now, I'm just getting used to it. Jul 13 11:27:46 other than your wireless, your RTC? Jul 13 11:28:24 Oh so it doesn't have one so can't keep time?? Jul 13 11:29:37 I don't follow you here. Jul 13 11:30:00 I can't set the time because the application crashes when I try and set the preferences. Jul 13 11:31:33 use NTP Jul 13 11:33:58 Right. Jul 13 11:34:08 How should that be set up? Jul 13 11:36:33 WTH I just rebooted and now can't acess the board's ssh over usb. Jul 13 11:36:50 Oh hasn't booted completely, longer than I thought. Jul 13 11:37:46 'date' in the terminal gives the correct time, and date. Jul 13 11:37:55 Or it did. Jul 13 11:39:32 Willdude123: it will work just by plugging it into the netowrk Jul 13 12:08:44 How can I find compatible power supplies on ebay? Is there a name for the plug? Jul 13 12:51:47 http://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/gpio how do I locate P8_10? Jul 13 12:55:20 Willdude123: having a magnifying glass helps Jul 13 12:55:37 or looking at the drawings Jul 13 12:56:13 There aren't any. Jul 13 12:56:44 And P8_10 isn't labelled anyway. Jul 13 12:57:12 P8 is labelled, and pins 1/2 and 45/46 are labelled Jul 13 12:57:21 so just extrapolate from that Jul 13 12:57:26 also, http://elinux.org/BeagleBone Jul 13 12:57:46 (well, interpolate :P) Jul 13 13:16:42 mmm... my /dev/fb0 gets created but I cannot see anything. Jul 13 13:17:14 i'm using an LCD4 on a beaglebone black, and i modified a v3.2 SDK kernel Jul 13 13:17:27 i guess cat urandom > fb0 should work uh? Jul 13 13:18:01 also: the pwm backlight and lcd gpio keys are working... it's just the panel that it's not working :-( Jul 13 13:18:40 maybe it's a clk issue? Jul 13 13:27:42 will bblack play youtube at 720p ? Jul 13 13:34:51 hello Jul 13 13:35:18 who of you guys can help me concering the beagle bone black pcb and schematic Jul 13 13:35:23 ? Jul 13 13:38:11 <_SY_> hello, FTDI cable has arrived, connected and booted beagle...I have a serial console configured using Putty 115200 Jul 13 13:38:40 <_SY_> I'm in the shell now... Jul 13 13:43:26 How do I enable a uart on the bbb? Jul 13 13:43:33 Can I just open it? Jul 13 13:43:36 Willdude123: black? Jul 13 13:43:44 Yeah Jul 13 13:43:55 you need a special cable, do you have that? Jul 13 13:44:05 http://circuitco.com/support/index.php?title=BeagleBone_Black_Serial Jul 13 13:44:12 Willdude123: ^^^ this one Jul 13 13:44:13 <_SY_> first identify a UART that provides everything you need...I use UART4 and UART5 Jul 13 13:44:20 <_SY_> then... Jul 13 13:44:34 I haven't got the cable, I want to connect it to something else. Jul 13 13:44:54 <_SY_> echo BB-UART4 > /sys/devices/bone_capemgr*/slots Jul 13 13:45:19 <_SY_> mount /dev/mcblk0p1 /media/BEAGLEBONE Jul 13 13:45:35 <_SY_> vi uEnv.txt Jul 13 13:46:02 <_SY_> Modify entry to: Jul 13 13:46:02 <_SY_> optargs=quiet drm.debug=7 capemgr.enable_partno=BB-UART4,BB-UART5 Jul 13 13:47:03 <_SY_> Then you can connect PINS P9-11 RXD, P9-13 TXD, P8-1 GND for UART4, P8-38 RXD P8-37 TXD or UART5 Jul 13 13:48:01 Which pins are they on? Can't see them here: http://stuffwemade.net/assets/Uploads/_resampled/resizedimage600667-hwio-beaglebone-ports2.png Jul 13 13:48:05 omfg: my LCD works! Jul 13 13:48:40 Willdude123: do you have the BBB manual? Jul 13 13:48:46 No Jul 13 13:48:51 there's a comprehensive figure of the headers there Jul 13 13:48:56 ok... let me fetch the link Jul 13 13:49:05 https://github.com/CircuitCo/BeagleBone-Black/raw/master/BBB_SRM.pdf Jul 13 13:49:13 Also, _SY_ I don't understand your "you can connect to " bit Jul 13 13:49:14 <_SY_> On the long black female connectors, download the BBB PDR, they are listeed Jul 13 13:49:41 exactly Jul 13 13:49:52 he said long and black haha Jul 13 13:50:17 Question: When I first boot the beagle bone black, does it have a desktop to work off of? Jul 13 13:50:40 Willdude123: look at pages 80 & 82 in the BBB_SRM.pdf Jul 13 13:50:44 <_SY_> The pins of a 9 pin D-Type used for TX/RX and GND, these are pins 2, 3 and 5....you need to cross over TX and RX for it to work...so you would connect pins 2 and 3 to the pins I mentioned above. Jul 13 13:51:42 I want to put Lbuntu as my OS how hard is that to do? Jul 13 13:52:17 _SY_: Why cross over I really don't understand. Also is there a website that has everything you've just told me on it? Jul 13 13:52:42 <_SY_> You need the image, a flasher and an SD card, using the flasher, write the image to the SD card, once complete, insert the SD card into the BBB, with the boot button pressed and power up...thats it. Jul 13 13:53:34 <_SY_> Ok, in simple terms, you have a mouth to talk with and ears to listen with....RX is the equiv of ears, TX is the equiv of your mouth.... Jul 13 13:54:15 <_SY_> Now both ends have the same, ears and mouth, but you have to cross the mouth with the ear, in order for it to work, or one end can't hear the other...makes sense? Jul 13 13:54:55 <_SY_> So imagine you have two yogurt cartens with a bit of string...one end you hold to your ear the the other end to the mouth, if you both have the same then you will cross over the strings. Jul 13 13:55:04 <_SY_> Ear to Mouth and Mouth to Ear... Jul 13 13:55:12 <_SY_> same thing, RX to TX and TX to RX. Jul 13 13:55:49 Err Jul 13 13:56:13 Ah so the tx of the BBB goes to the RX of the thing I'm txing 2 Jul 13 13:56:15 *to Jul 13 13:56:26 <_SY_> Yep Jul 13 14:00:37 <_SY_> Is there anyone here who can help me debug my BBB with FTDI cable? Jul 13 14:01:19 make sure its 3v Jul 13 14:02:05 That makes sense! I knew that already.# Jul 13 14:02:15 <_SY_> it is...I'm connected to shell via serial port no problem, just not sure what I can do next....I've logged into the BBB, but it won't connect to the network, need help fault finding. Jul 13 14:02:59 _SY_: its a unix machine, fix it accordingly ;) Jul 13 14:03:42 <_SY_> thats brillant....but I'm not that experienced with Unix, hence the call for help :) Jul 13 14:06:05 microcontrollers may not be your best first linux experience ;) Jul 13 14:07:12 <_SY_> When I say not experienced, that isn't quite true...I use Linux at work on a daily basis and very experienced with QNX...but I haven't had to fix a BBB that fails to boot with FTDI before. Jul 13 14:08:01 <_SY_> It boots to serial, I log in with root password, I've had a look at the journalctl -xb, but nothing jumps out to explain why it won't boot up normally with network access Jul 13 14:08:40 journally will hve nothing to do with network Jul 13 14:08:43 journalling* Jul 13 14:08:51 somethings up with connmanager SY Jul 13 14:08:52 most likely your dhcp server is timing ou Jul 13 14:08:52 t Jul 13 14:09:37 <_SY_> I'll go through the montions of setting up my static IP again, might have missed or messed something up Jul 13 14:10:22 SY : cd /usr/lib/connman/test/ Jul 13 14:10:37 then run ./get-services Jul 13 14:11:07 <_SY_> I just tried that, but I don't think its available when booting using FTDI. Jul 13 14:11:20 what are you talking about Jul 13 14:11:26 <_SY_> got several errors reported Jul 13 14:11:36 doesnt matter how you access sit Jul 13 14:11:40 the console spits out of ttyS0 Jul 13 14:11:44 all ftdi is doing is giving you a console on ttyS0 Jul 13 14:11:49 has nothing to do with networking Jul 13 14:12:08 <_SY_> ok, well I am in /usr/lib/connman/test Jul 13 14:12:18 <_SY_> I entred: ./get-services Jul 13 14:12:20 now run ./get-services Jul 13 14:12:20 <_SY_> and get: Jul 13 14:13:00 <_SY_> http://pastebin.com/zjD4nGFG Jul 13 14:13:56 your all hosed up Jul 13 14:14:06 time to reflash you system Jul 13 14:14:25 <_SY_> again.... Jul 13 14:15:04 that is just saying dbus is not running Jul 13 14:15:10 why dbus is not running is the next question Jul 13 14:15:17 but reflash sounds logical to fix it Jul 13 14:15:20 Hi! I tested my BBB and boot time is 25". With ubuntu 13.04 the dmesg show 8.8 seconds, then 17" forgotten. How I can reduce the boot time ? Jul 13 14:15:38 drieran: that would be a #ubuntu qustion Jul 13 14:15:50 <_SY_> will start over. Jul 13 14:16:07 ubuntu is fine with 8 seconds. The problem is before ubuntu Jul 13 14:16:42 your not going to increase that speed Jul 13 14:16:49 beagle self tests, and the like Jul 13 14:17:57 <_SY_> ty for help, will go watch a movie, whilst BBB is flashing. Jul 13 14:23:32 SY when reflashing and you have the debug cable you can watch the progress somewhat Jul 13 14:23:40 just login Jul 13 14:23:59 journalctl -f Jul 13 14:24:22 currently mine is saying Extracting rootfs Jul 13 14:24:57 so thats gives me some security it is working over and beyond watching leds flash Jul 13 14:25:27 now its populating VFAT partition :) Jul 13 14:35:59 here another warm and fuzzy while reflashing watch -n 4 df /dev/mmcblk1p* Jul 13 15:19:10 hi everyone, I am a newbie, does anyone know any good books on getting into beagle board Jul 13 15:38:02 I think my gpio is inverted on a certain pin, low gives high and vica versa. Jul 13 15:38:23 Hi, I am a newbie, does anyone know any good books on getting into beagle bone Jul 13 15:39:21 dixit, http://www.amazon.com/Bad-Bone-Electronics-Beaglebone-BeagleBone/dp/1627051376 Jul 13 15:40:35 thanks @hatguy Jul 13 15:40:42 np Jul 13 15:41:04 Will this book help me even if i am a beginner at linux, currently I know arduino and java Jul 13 15:45:17 dixit, no idea... just know it exists Jul 13 15:48:03 having trouble sharing internet with bbb over usb with mac Jul 13 15:56:53 what Jul 13 15:56:58 oh ok Jul 13 15:57:09 thanks for help though @hatguy Jul 13 16:00:02 * dixit 'waves hello' Jul 13 16:30:39 I think my gpio is inverted on a certain pin, low gives high and vica versa. Jul 13 16:30:45 Why? Jul 13 16:31:54 <_av500_> turned the board upside down? Jul 13 16:33:22 Haha Jul 13 16:33:23 No Jul 13 16:42:02 I really don't get how to set up uart on bbb.

I have c code that will toggle between high and low. it appears that high is at 3.3 and low is at 0. however, when i dont export a value, 3.14 volts are still output on the port. is there a way to change this "default" behavior? Jul 13 17:07:25 define 'don't export a value' Jul 13 17:07:35 Do you mean when you have not set the pin as output? Jul 13 17:10:06 the c program does that when it exports the pin. but right before exiting the program the pin gets unexported which im guessing tells it to go back to default settings. default appears to be outputting some voltage, which is not desired Jul 13 17:13:08 using the code here basically https://github.com/derekmolloy/boneDeviceTree/tree/master/gpio Jul 13 17:14:05 <_av500_> circuit: pastebin the full thing Jul 13 17:14:09 <_av500_> pastebin.com Jul 13 17:14:35 https://github.com/derekmolloy/boneDeviceTree/blob/master/gpio/TestApplication.cpp Jul 13 17:15:04 the library the test application is using is here https://github.com/derekmolloy/boneDeviceTree/blob/master/gpio/SimpleGPIO.cpp Jul 13 17:24:05 What's the Min baudrate of the UARTs?

Jul 13 18:35:32 this is not rpi, THIS IS #BEAGLE! so the answer is obviously: yes Jul 13 18:36:00 yes!!!!!! *fist pump* Jul 13 18:36:44 great! im trying to make a beaglemesh network connected via wifi Jul 13 18:37:02 what do you want to use as meshing software? Jul 13 18:37:02 and ethernet to personal ap routers. Jul 13 18:37:12 cjdns. Jul 13 18:38:06 that does not build a mesh network, it builds an overlay network over an existing network Jul 13 18:38:49 oh. i was told only the original version did that. Jul 13 18:39:24 well.. i can be mistaken, but to my understanding cjdns is an overlay network, not a mesh network Jul 13 18:39:51 i was told its a layer 2 and 3 Jul 13 18:40:08 gimme a couple of minutes to read the docu Jul 13 18:40:31 ok Jul 13 18:42:17 Is anyone having trouble with permissions when loading DT overlays? Jul 13 18:44:14 I need to be root, sudo does not even work.. Jul 13 18:45:09 voem: yes, it's an overlay network Jul 13 18:46:15 ok. how does one come to that conclusion though? i get all these different answers from people. Jul 13 18:46:48 quite simple: cjdns never talks about how to set up a wireless device to do meshing Jul 13 18:47:13 all documents i've read in the last couple of minutes assume that cjdns can reach its peers somehow Jul 13 18:48:15 compare that to the B.A.T.M.A.N. documentation, where you have a complete section devoted to how to set up the wireless device that it can properly do what you need it to do.. and a list of compatible devices Jul 13 18:48:43 mmmm.... Jul 13 18:51:18 hi, i just have one question Jul 13 18:51:22 so to be considered true mesh a protocol has to control the hardware interactions. Jul 13 18:52:16 do the usb storage devices are automatically mounted on the beaglebone? Jul 13 18:52:50 voem: uhmm.. it's the definition of the term. a mesh network is a wireless network of multiple devices that potentially do not see all devices participating in the network, thus have to forward messages for each other in some way or other to enable communication between all participating devices Jul 13 18:53:43 isnt that cjdns? Jul 13 18:53:57 voem: while an overlay network is a network build ontop of an existing network. there potentially all nodes can talk to each other directly, but for some reason or other don't choose to, instead they route messages from node to node Jul 13 18:54:06 oh... Jul 13 18:54:19 voem: cjdns does not do anything special with wireless Jul 13 18:54:43 bursy: depends on what OS/distro you run Jul 13 18:54:49 well i know theres a wireless mesh and just a term mesh. Jul 13 18:55:01 not all mesh is wireless. Jul 13 18:55:06 KotH: angstrom Jul 13 18:55:11 bursy: no idea... Jul 13 18:55:22 voem: er... well... no! Jul 13 18:55:38 the internet is a mesh no? Jul 13 18:56:17 no to be argumentative. im merely trying to understand better. Jul 13 18:56:18 voem: those people who are working in the field have a certain nomenclature. people who are not trained in the art often use the terms loosely, or totally different, and make things confusing Jul 13 18:56:41 KotH: ok because i am not a linux user usually and i just want to copy a file from a usb device to the beaglebone Jul 13 18:56:46 voem: a network is per definition a "mesh", but people dont talk of it being a "mesh" but rather a "graph" Jul 13 18:57:07 voem: the term mesh network is "reserved" for wireless mesh networks Jul 13 18:57:25 ok. Jul 13 18:57:29 bursy: you can always mount by hand Jul 13 18:57:42 bursy: use "mount /dev/ /mnt" Jul 13 18:57:56 bursy: dont forget to unmount using "umount /mnt" before unplugging the usb stick Jul 13 18:58:32 KotH: ok is there a blankspace before /mnt? Jul 13 18:58:41 yes Jul 13 18:58:55 bursy: http://linux.die.net/man/8/mount Jul 13 18:59:16 KotH: thanks Jul 13 18:59:45 koth, so adhoc is also a protocol? Jul 13 19:00:25 voem: adhoc in 802.11 context means "without an access point", it does not denote a certain protocol Jul 13 19:01:01 im trying to minimize the mem usage on my bbb Jul 13 19:01:16 i dont want to add another protocol if i dont have to. Jul 13 19:02:06 im told to just throw my wifi into adhoc and cjdns can autopeer. Jul 13 19:02:26 dunno if that is what batman does? Jul 13 19:03:08 hmm... Jul 13 19:03:18 with that it might work Jul 13 19:03:27 the "adhoc + cjdns" Jul 13 19:03:51 but i dont know how 802.11 behaves if you have multiple devices that cannot see eachother Jul 13 19:04:31 im told it should scale to size of current internet (2 months ago) Jul 13 19:04:33 batman does a bit more than just running adhoc... it builds a reachability matrix and routing system ontop of 802.11 Jul 13 19:05:24 i havent had a deep look at cjdns, thus i dont know whether this claim is true.. but knowing how large scale routing performes, i would doubt that very much Jul 13 19:05:44 for reference: the world wide inter-ISP routing table is several 100MB large Jul 13 19:06:09 last number i heard 10y ago spoke of 400MB, but i dont know how realiable that source was Jul 13 19:06:25 yeah cjdns prunes to 1mb Jul 13 19:06:49 but its obligated to keep track of nodes in close address space. Jul 13 19:07:04 and this routing table uses a tremendus amount of pruning by prefix (no network smaller than /19 is in there, unless it's a PI) Jul 13 19:07:38 hmm...1mb... that sound very little for internet scale of things Jul 13 19:07:51
