**** BEGIN LOGGING AT Wed Sep 10 02:59:58 2014 Sep 10 03:21:38 I've got a question about starting a python script that requires a console on boot. Sep 10 03:21:57 It runs just fine, but I don't know enough about systemd to tell it to run inside a console. Sep 10 03:22:58 Or would it be better to follow this guide: https://fedoraproject.org/wiki/Systemd#How_do_I_set_automatic_login_on_a_virtual_console_terminal.3F Sep 10 03:23:04 And then set up the process to run on tty8 Sep 10 04:55:27 join #barebox Sep 10 04:55:30 fuck Sep 10 06:51:45 hi to all Sep 10 06:52:12 i used bone-debian-7.6-console-armhf-2014-09-04-2gb.img with a sd Sep 10 06:54:04 the bbb boot but how can i connect to it? no usb 192.168.7.2 Sep 10 06:56:18 gerod: what OS do you use? Sep 10 06:57:05 win 7 Sep 10 06:57:10 why? Sep 10 06:57:55 never tried on windows, did you follow the instructions? Sep 10 06:58:15 img written to sd Sep 10 06:58:18 gerod connect serial console Sep 10 06:58:30 how? Sep 10 06:58:34 otherwise you do not know whats going on Sep 10 06:58:43 use ftdi compatible cable Sep 10 06:58:53 i dont have Sep 10 07:18:33 I am new to Yocto project, but will start exploring it with my beagle board. Does any one have done it ? any one has any recommendation. Sep 10 07:19:37 sachin_: yocto has good documentation, and the meta-ti layer (that you would be using) has http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/tree/README Sep 10 07:19:56 sachin_: should be enough. Sep 10 07:21:37 Ok Thanks. But my main concern is If I start exploring and trying to map to my project It is going consume my time. So does it will help for future embedded projects. Does community people started taking interest on. Will it help to improve as addition skill Sep 10 07:22:00 sachin_: that sentence makes not much sense. Sep 10 07:22:37 Ok fine. I will try for my beagleboard. Sep 10 07:22:49 with Angstrom OS. Sep 10 10:16:39 hi, my bbb won't boot until it's connected to the network, how should i fix it! ? Sep 10 10:24:35 whash: what makes you think it doesn't boot if it's not connected to the network? Sep 10 10:25:33 i have lcd connected to it, it stuckes when loading kernel (pinguin logo on upper left) Sep 10 10:27:16 but when i attach the ethernet cable to it (dhcp configured), ... it comes up Sep 10 10:30:27 whash: sounds like something in your boot process. I'd look at serial console and boot logs. Sep 10 10:34:51 tbr: i dont have any serial cable right now, it is my uEnv.txt: http://pastebin.com/aynAT0V8 can it be related to the problem? Sep 10 10:35:18 whash: no logs, no analysis. simple as that. Sep 10 10:35:58 sorry here it is: http://pastebin.com/injxg88W Sep 10 10:36:26 that's not a boot log Sep 10 10:38:25 i know but i thout it's related to bootloader, btw is there any way to get boot log without serial cable? Sep 10 10:48:37 Hi, I have a question about BBB Sep 10 10:49:33 I have only 4.7V on SYS_V5 rail and USB, inspite of powering from PC USB or external 3A power adapter Sep 10 10:49:36 Is it ok? Sep 10 10:52:26 hello, can you help me about code python to control lcd 20*4 with beaglebone black Sep 10 10:52:55 Apologies for disturbing. Could anybody confirm if the Beaglebone White is discontinued? Thanks! Sep 10 10:54:59 hi Sep 10 10:55:46 hello Sep 10 11:12:08 hey Sep 10 11:14:40 tahoemph: mind fixing your network connection? Sep 10 11:15:32 Maybe someone here uses GEDA pcb and can help me with this error? Sep 10 11:16:37 matwey: yes , the bbb infact uses 3.3V Sep 10 11:16:48 so the 4.7 is converted to 3.3v Sep 10 11:18:43 nivw__: it's easier if you ask in ##geda Sep 10 11:18:49 tbr: I am considering installing a water flow counter to my home. as the one I use in the gardening irrigation system Sep 10 11:19:06 this is also a big data concept... Sep 10 11:19:20 ok Sep 10 11:19:32 thanks KotH, I was only aware of a geda channel in OFTC Sep 10 11:19:52 nivw__: hmm.. it could have been on oftc Sep 10 11:20:04 nivw__: i dont keep track on whcih network these channels are, as i'm on both :) Sep 10 11:21:10 thanks KotH Sep 10 11:21:30 tbr, I don't really know what to do with the data yet Sep 10 11:23:34 nivw__: go wild, log it all, do interesting analysis later Sep 10 11:23:55 yep Sep 10 11:24:07 corellate water consumption with power consumption with chili stew cooking, etc ;) Sep 10 11:24:25 and the odor in your toilet ;) Sep 10 11:27:45 this may alert of a leak... Sep 10 11:28:15 hi koth Sep 10 11:28:43 hey woglinde Sep 10 11:28:55 woglinde: wie geht's wie steht's? Sep 10 11:29:28 good Sep 10 11:29:35 hotel is booked for elce Sep 10 11:29:48 flight too Sep 10 11:31:09 * tbr is all riled up for ELCE Sep 10 11:32:30 what is ELCE? Sep 10 11:33:18 http://events.linuxfoundation.org/events/embedded-linux-conference-europe Sep 10 11:33:19 woglinde: meh.. i still need a hotel Sep 10 11:33:28 koth mom Sep 10 11:33:30 woglinde: also: seek out the guy with the chocolate at ELCE :) Sep 10 11:33:31 KotH: tried radisson yet? Sep 10 11:33:36 tbr: fully booked Sep 10 11:33:42 also by phone? Sep 10 11:33:49 tbr: hmm.. didnt do that Sep 10 11:33:59 their website is lying Sep 10 11:34:01 tbr: good idea, i'll try later today Sep 10 11:34:29 as said previously, I got monday added to my reservation despite site claiming full Sep 10 11:37:02 oh.. that was monday? Sep 10 11:37:06 * KotH takes notes Sep 10 12:21:07 Hi everyone Sep 10 12:21:34 Is anyone able to help me with USB hub problem on my linux+BBB board? Sep 10 12:22:15 sure. no hub, no problem Sep 10 12:22:44 Yeap, sound about right, but I need this HUB to work. Sep 10 12:23:15 well.. _WHAT_ is your problem? Sep 10 12:23:21 If I plug it after boot everything works nice, if I plug it and than boot, it is not recognized at all Sep 10 12:24:42 fun USB times, courtesy of musb Sep 10 12:25:13 I do not know why, I searched google, etc. and many people experience similar problem, but so far I did not found any solution to it. Sep 10 12:25:48 konrad: which distro are you running on it? Sep 10 12:25:49 If it is plugged and working, and you reboot, does it work? Sep 10 12:26:32 nope, it is not working in that case either. Sep 10 12:27:27 machinekit, which is kernel 3.8.13xenomai-bone26.1, based on the official Debian release for the BeagleBone using Robert C Nelson's omap-image-builder scripts Sep 10 12:28:09 konrad: there have been lots of fixes in the usb code since 3.8 Sep 10 12:28:15 konrad: try a newer one Sep 10 12:29:44 no idea about the xenomai patched stuff and how in sync with latest fixes that is Sep 10 12:30:00 but yeah, trying something more recent might be an idea too Sep 10 12:30:15 "differently broken" ; Sep 10 12:30:18 ;) Sep 10 12:31:29 probably you can try to reset the supply of the USB host connector, but I don't know how :) Sep 10 12:31:45 xenomai is real time kernel mod Sep 10 12:32:44 konrad: I know that. the question is how much it's kept in sync with RCNs kernel Sep 10 12:33:22 no idea, searching now Sep 10 12:40:41 I think I might have to compile it my self, I can not find anything fresher than 3.8 Sep 10 12:49:05 thanks, bye Sep 10 13:27:39 hi all... i need help to configure my BBB, can anyone help? I need 3 physical ethernet ports on the BBB.. i have 2 right now (the ethernet port and the usb host that i hooked to an ethernet adaptor)... i need a 3rd one so i am hoping to use the mini-usb to that end. I connected an ethernet adaptor to it but it always comes up as usb0 and i cannot have the ethernet adaptor working... anyone know what should be disabled/enabled to a Sep 10 13:32:31 samantha_a: use an usb hub on the host port Sep 10 13:36:51 tbr: i know i could do that... but specifically for what i intend to do... i need 3 physical ports and a hub, a switch or connecting to a desktop using the usb cable just won't allow me to do what i want.. thanks for the answer, but i really need that physical ethernet adaptor to be hooked up Sep 10 13:37:14 <_av500_> samantha_a: I think you need a hardware change to use the mini USB as host Sep 10 13:37:23 <_av500_> it is not wired for that Sep 10 13:37:28 correct Sep 10 13:37:36 <_av500_> so for all practical purposes, BBB has one USB only Sep 10 13:37:40 also I wouldn't want to rely on usb nor usb-ethernet Sep 10 13:39:28 really?.... ahhhh... i thought sw config could fix that up.... Sep 10 13:42:47 @_av500_... you're sure nothing can be done? Sep 10 13:43:34 samantha_a: you could use a phytec wega.. it has 2eth+usb Sep 10 13:47:31 samantha_a: Use two USB Ethernet adapters and a USB hub on the USB host port. Sep 10 13:47:52 samantha_a: Or, use one of the many SPI-connected Ethernet modules out there. Sep 10 13:48:50 samantha_a: Or, use a different board with more Ethernet ports--the Alix boards from PCEngines have models with that many. Sep 10 13:56:39 <_av500_> samantha_a: something can be done Sep 10 13:56:43 <_av500_> soldering involved Sep 10 13:56:44 <_av500_> google for it Sep 10 13:56:48 <_av500_> it has been discussed Sep 10 13:57:02 <_av500_> agmlego: SPI is dead slow, no? Sep 10 14:08:33 _av500_: I think you can usually get at least 10Mbps out of iot. Sep 10 14:08:50 _av500_: But since she has not really mentioned what the hell she is doing... Sep 10 14:08:50 <_av500_> wow :) Sep 10 14:30:10 _av500_: the beagle spi? or spi in general? i thought spi is used on mainboards for usb, pcie etc. interfaces :o Sep 10 14:31:37 <_av500_> werm Sep 10 14:31:38 <_av500_> erm Sep 10 14:31:39 <_av500_> no Sep 10 14:34:18 day: PCIe is an LVDS system, as is USB. Sep 10 14:34:42 day: Mainboards tend to throw USB controllers onto a PCI bus, which itself is generally fed off a PCIe to PCI bridge. Sep 10 14:35:04 day: Mainboards do tend to have an I2C bus or two for hardware sensors, using the SMBus software protocol. Sep 10 14:35:23 sorry agmlego.....just need to have traffic on ethernet cable... whether its 100mps or 10... it's fine for me... just ned data to flow... Sep 10 14:35:27 :-) Sep 10 14:35:45 samantha_a: I really, really think you are using the wrong board for this. Sep 10 14:36:30 samantha_a: But, may I ask what you are actually trying to accomplish? Sep 10 14:41:29 well.... i am using LLDP protocol as a discovery mecanism for ports and it needs physical ports Sep 10 14:41:46 i was hoping to have 3 physical interfaces Sep 10 14:41:54 no virtual ones Sep 10 14:45:06 agmlego: ty Sep 10 14:45:40 samantha_a: OK, but what is the overall project? Sep 10 14:50:05 agmlego: doesnt a differential signal require two data lines? i2C only has one iirc. Sep 10 14:52:10 Hi Sep 10 14:54:37 day: I2C is not a differential bus. It is, however, a two-wire interface (hence TWI), with a clock line and a data line. Sep 10 14:55:11 (and a ground line which is often forgotten) Sep 10 14:55:34 Sure, but since *every* bus requires that, it is irrelevant. Sep 10 14:55:45 agmlego: yes. but your LVDS threw me of. Or doesnt it mean low voltage differential system? Sep 10 14:55:51 It does. Sep 10 14:56:04 I2C is *not* used for PCIe or USB... Sep 10 14:56:20 It is used for SMBus, for the hardware sensors around the mainboard and peripherals. Sep 10 14:56:25 Also for EDID. Sep 10 14:56:32 agmlego: :X Sep 10 14:56:46 im miss read it completely Sep 10 14:57:05 Heh. It happens. Sep 10 14:58:10 agmlego: does the pcie bus has a name as well? Sep 10 14:58:15 <_av500_> yes Sep 10 14:58:16 <_av500_> PCIE Sep 10 14:58:23 day: What _av500_ said. Sep 10 14:58:27 oh shit Sep 10 14:58:33 <_av500_> though I call mine Bob Sep 10 14:58:45 <_av500_> Bob, pass me the framebuffer please Sep 10 14:58:48 day: Time for more caffeine maybe? ;-P Sep 10 14:59:07 17:00 time to go home :) Sep 10 14:59:24 Or that, whichever. Sep 10 14:59:33 <_av500_> day: look for night Sep 10 14:59:33 but also caffeine :p Sep 10 14:59:52 Six more hours here to that. Sep 10 15:00:24 east coast i assume Sep 10 15:00:58 day: Detroit area, but same timezone. Sep 10 15:01:26 i almost managed to get an internship in that region. but then i didnt :( Sep 10 18:56:49 question... can i use the hdmi to have another ethernet interface? Sep 10 18:59:29 <_av500_> no Sep 10 18:59:45 <_av500_> unless you can live with ethernet over i2c Sep 10 19:01:07 not aware of i2c.. am not a hw guy... Sep 10 19:01:25 don't really care about the speed.... Sep 10 19:01:56 <_av500_> so, no Sep 10 19:02:13 do you suggest me some hardware to add to my beagle board? Sep 10 19:04:36 simonz: USB Ethernet interfaces exist. Sep 10 19:04:56 Also, SPI-connected Ethernet modules exist. Sep 10 19:05:43 am pretty dumb with these components... i dream of a plug&play solution ;-) Sep 10 19:05:59 well. what exactly are you going to do? Sep 10 19:06:09 <_av500_> usb hub Sep 10 19:06:12 <_av500_> usb2eth modules Sep 10 19:06:15 <_av500_> done Sep 10 19:06:27 can these be connected to the beagle bone and an ethx appearing in there like magic? without using my 2 precious usb ports ;-) Sep 10 19:06:49 huh? Sep 10 19:06:52 <_av500_> no Sep 10 19:06:53 <_av500_> hence the usb hub Sep 10 19:09:46 Hi, I have a problem with the BBB. When I Ioose the wifi signal (because someone turn off the router or i get out of the wifi cover) the BBB doesn't automatically reconnect to the known wifi signal Sep 10 19:10:52 What should I do, for the BBB to reconnect automatically once the wifi signal is on again? Sep 10 19:11:39 Mario___: Use management software like connman or wicd to automatically reconnect. Sep 10 19:12:36 I am currently using connman but is not working Sep 10 19:12:49 what type of configuration should I use? Sep 10 19:13:25 One that does automatic reconnection. Sep 10 19:13:30 * agmlego is not familiar with connman. Sep 10 19:13:40 But I am sure there is documentation on the program. Sep 10 19:14:35 * djlewis recalls connman was evil if one tried to use static ip. Sep 10 19:15:07 We are trying to use dhcp Sep 10 19:16:47 do you have any suggestion? Sep 10 21:22:29 Anything interesting going on in the beaglebone world today ? Sep 10 21:23:57 Nope. Everyone is out either swimming, or playing with their Edisons. Sep 10 21:24:44 Define Edisons Sep 10 21:25:12 Only Edisons I know of is batteries Sep 10 21:26:41 Intel Edison, announced yesterday. Sep 10 21:26:57 Little dual-core x86 dev platform 10% larger than an SD card. Sep 10 21:28:18 hmm ill have to go google that, and very surprised I did not get any kind of email indicating that. must fix that Sep 10 21:28:32 Sparkfun had a post about it. Sep 10 21:28:36 Hackaday has had two. Sep 10 21:28:44 THis was not a silent announcement. Sep 10 21:31:42 recently reinstalled my desktop as in a couple months ago i gues i hmm gues i never had HAD notifications Sep 10 21:32:26 possible i read about it just forgot about it. Sep 10 21:32:57 "The best part? Edison will retail for about $50. That’s a dual core x86 platform in a tiny footprint for just a few bucks more than a Raspberry Pi." wonder if these guys actually tried getting an rPI for retail cost Sep 10 21:34:48 m_billybob: Even still it is definitely in the same ballpark as the other common SBCs. Sep 10 21:36:09 Timing is way late. I mean its interresting, but i was looking for somethign like this well over a year ago. Now im kind of liking arm Sep 10 21:36:31 I'd probably still buy one Sep 10 21:36:55 If for nothing else. to have something else to tpy with Sep 10 21:41:10 I really like that it is so physically small, and multicore. Sep 10 21:41:34 And, being an Intel product and x86, probably has really strong Linux driver support for all the hardware. Sep 10 21:41:40 yeah thats very nice Sep 10 21:41:51 (and gcc will optimize pretty effectively for it) Sep 10 21:41:57 and i did hear of this -> IntelGalileo I did not realize they were related Sep 10 21:42:15 Yeah, though those are different in a lot of ways. Sep 10 21:42:30 is that minnowmax out? Sep 10 21:42:42 Galileo was an i586 QUark; Edison is a pair of underclocked Atom cores with a low-speed QUark. Sep 10 21:42:51 Arduino i have no love for Sep 10 21:43:52 im kind of an MSP430 fan, and if i needed mroe horsepower I'd go with an M0+ /M3 devboard Sep 10 21:44:11 m_billybob: +1 to msp430 ! Sep 10 21:44:12 Depends on what level of horsepower, really. Sep 10 21:44:14 I have 4 TI LM120 kits here in front of me Sep 10 21:44:26 But yeah, for low-performance stuff, MSP430 is nice. Sep 10 21:44:42 hard to beat the MSP430 for low power Sep 10 21:45:02 I like the Edison and others because I can do high-level things like vision processing with them, and still get decent realtime performance for hardware control. Sep 10 21:45:10 I've only ever used the 2553 but its still got plenty of stuff Sep 10 21:45:24 Yeah, I am a fan of the architecture for its purpose. Sep 10 21:46:05 I'm a "tweaker / tinkerer Sep 10 21:46:27 love to tinker with things and tweak for efficiency Sep 10 21:54:00 although heh, would have liked a better clockspeed Sep 10 21:54:32 really cant complain though, and yeah looks like the sleeping giant finally woke up Sep 10 21:56:21 m_billybob: Well, the Atom itself is normally 1.2GHz. Sep 10 21:56:49 this is no heatsink or fan though Sep 10 21:56:59 It is underclocked to 500MHz for power consumption--I have no doubt it is reasonably easy to undo that if you have a stiff enough power supply and a good heatsink. Sep 10 21:57:02 Right. Sep 10 21:57:21 im reading the hardware guide right now Sep 10 21:57:30 seems there is a BSP already for it too Sep 10 21:57:31 And, but the hands-on review by an Intel engineer from a different project, the unit does not get hot at all. Sep 10 21:57:37 Of course there is. Sep 10 21:57:47 YOu think Intel would issue something like this without? ;-P Sep 10 21:57:55 yeah but im curious for which OS(s) Sep 10 21:58:03 definately LInux Sep 10 21:58:08 Yocto. Sep 10 21:58:17 And maybe Debian and Android down the road. Sep 10 21:58:28 intel can't recognise linux if they're in bed with m$ surely .. Sep 10 21:58:40 ...what? Sep 10 21:58:42 its x86 no BSP required for those lol well maybe for the periphs Sep 10 21:58:44 it'll have to run windoze inbedded :p Sep 10 21:58:54 veremit: Are you trolling? Sep 10 21:59:00 pfft Sep 10 21:59:04 windows embedded Sep 10 21:59:05 * veremit goes back to lurkin Sep 10 21:59:15 Because Intel is the golden child in the Linux world for device driver support. Sep 10 21:59:17 and reflashing my new router >,< Sep 10 21:59:29 Like, Linus uses their drivers as the model. Sep 10 21:59:30 thats cos they actually do coding Sep 10 21:59:36 rather than farm it out Sep 10 21:59:49 So, I have no idea where you are going with that "in bed with MS" stuff. Sep 10 21:59:50 and if you're writing it once in C ... Sep 10 22:00:05 (never mind the fact that Yocto is an Intel-funded project) Sep 10 22:00:07 its their license I'd imagine Sep 10 22:00:09 This'll run with windows on it i have no doubt. Sep 10 22:00:28 m_billybob: Probably, though with no obvious display output, it might be trikcy to do so. Sep 10 22:00:28 wont run well though Sep 10 22:00:51 naw thats all configurable with windows embedded Sep 10 22:01:02 its kind of like linux, but non OSS Sep 10 22:01:09 very modular Sep 10 22:01:59 oh andthe most important part when only paying 50 bux for this sort of thing. the OS would cost more than the hardware Sep 10 22:02:25 Yup. Sep 10 22:03:34 ok, im a bit lost with this ----> Dual Core IA-32 @ 500 MHz, 32-bit Intel® Atom™ Processor Z34xx Series @ 100 MHz Sep 10 22:03:50 The 100MHz is the Quark onboard. Sep 10 22:03:55 There are three cores. Sep 10 22:03:55 100MHz FSB ? Sep 10 22:03:59 ah Sep 10 22:04:02 video ? Sep 10 22:04:09 Two x86 Atom cores, one Quark realtime processor. Sep 10 22:04:12 No. Sep 10 22:04:22 somethign similar to a PRU ? Sep 10 22:04:22 The QUark is sort of Intel's PRU. Sep 10 22:04:39 The Galileo solely uses the Quark, at 400MHz, IIRC. Sep 10 22:05:18 Quark is an i586 architecture designed for low-power, low-performance things like IO maintenance and such, much like the PRU. Sep 10 22:06:18 been so busy with the BBB forgot to pull my head out of the sand to look around once in a while Sep 10 22:07:11 Heh. Sep 10 22:07:28 Yeah, I think it is going to be an interesting product, and maybe will shake up the SBC market. Sep 10 22:15:23 Intel has a way od disturbing the water around itself Sep 10 22:15:27 of* Sep 10 22:24:51 Ok, i want one. Sep 11 00:06:23 hi guys i had some questions. I have been using the l298n h bridge breakout that i bought on ebay. I had them working fine with my arduino's. I am not sure if I am sending pwm wrong to the device as i have had two work initially with speed control of the hbridge but after using it for a bit it has stopped working. do you guys recommend a better hbridge to use with the beaglebone and know what i could have done to damage the hbrid Sep 11 00:27:33 probably toasted the beagle pins .. Sep 11 00:27:54 although the h-bridge board has a transistor array, no? Sep 11 00:29:48 have you tried them again with an arduino? Sep 11 00:30:01 the arduino has a much more protected and higher current outputs than the beagle Sep 11 00:45:04 ok I gotta sleep .. nite all Sep 11 01:10:18 d Sep 11 02:22:12 The topic answers one question I had, Ordered faster than produced, now I'll have to find a place I can back order one from :P Sep 11 02:46:57 where do start-up scripts for the debian image go? Sep 11 02:47:30 just put bash scripts in /lib/systemd/? Sep 11 02:50:07 On RaspPi's it's been in /etc/rc.local iirc? Sep 11 02:50:19 IDK Beagle stuff yet, intending to learn soon :) Sep 11 02:51:01 ha, it's tough finding info right now since the major kernel change... a lot of articles are now incomplete or wrong Sep 11 02:51:26 You could try that, but someone else who knows will likely be in here soon :) Sep 11 02:51:51 (If you don't know, it's best to SAY you don't know, and realize it, that's good engineering :P) Sep 11 02:51:52 both /lib/systemd and /etc/init.d/ Sep 11 02:52:19 script in init.d and then service referencing it in systemd? Sep 11 02:52:53 either or.... systemd runs any script under /etc/init.d/ that doesn't have a matching service file.. Sep 11 02:53:11 oh nice, that's very simple **** ENDING LOGGING AT Thu Sep 11 02:59:58 2014
