Is switched tho, IIRC Jul 12 06:27:04 so shuts down when BBB powers down. Jul 12 06:27:12 oh.. Jul 12 06:27:14 bugger Jul 12 06:27:14 joho! Mr Packethead! Jul 12 06:27:17 VDD_5V is always on.

Jul 12 06:49:28 ds2: yes, it is flat Jul 12 06:49:41 seems like all of kiwiland is a huge mountain Jul 12 06:49:46 (lotr) Jul 12 06:49:50 ahh.

Jul 12 06:52:28 no, bottom layer of a two layer Jul 12 06:52:40 so lucky. Jul 12 06:52:55 then why a dremel? Jul 12 06:53:04 cut some track Jul 12 06:53:11 wow Jul 12 06:53:15 like a boss Jul 12 06:53:18 I usually use an xacto knife for that Jul 12 06:53:18 :3 Jul 12 06:53:26 you can do Jul 12 06:54:17 i like the dremel with an engraving bit Jul 12 06:54:24 it requires less force Jul 12 06:54:28 and you dont' slip Jul 12 06:54:37 the vibration sends the dremel all over Jul 12 06:54:54 no. Jul 12 06:55:07 anyway, back shortly. Jul 12 06:58:42 just got my BBB today! but when I connect I don't get the green banner saying your board is connected instead it has a feild for me to enter my boards ip add. Jul 12 06:59:08 and the bone script doesnt' work I'm on ubuntu 12.04 lts Jul 12 07:01:20 hi guys gm... anyone knows how to do serial interrupt on BBB Jul 12 07:04:30 to update the BBB you have to have an sd card huh? Jul 12 07:04:54 it helps to have on Jul 12 07:05:06 one Jul 12 07:06:50 I currently don't have one I know I should've just bought one but my friend has a bunch they don't use b/c the upgraded to a bigger card for their phones. can one use a usb stick? thumbdrive? Jul 12 07:07:20 to upgrade? Jul 12 07:08:19 yes and no Jul 12 07:08:23 it cannot boot from the usb stick Jul 12 07:08:29 so you need some sw already running Jul 12 07:08:37 that could read new data from the stick Jul 12 07:08:38 etc.. Jul 12 07:09:04 let's call it "non-standard" Jul 12 07:09:10 getting a $5 sdcard is easier Jul 12 07:11:10 well right now I just have the BBB Rev a5c hooked up to my laptop running ubuntu 12.04 using the usb cable. but It won't do step 3 right Jul 12 07:12:58 and i can't get it to say "your board is connected" SNxxxxxxxx etc Jul 12 07:13:31 it askes for it's own ip Jul 12 07:23:43 mrpacket_: dont worry, i wont emmigrate soon. there are still things i need to do here in chocolate land Jul 12 07:30:11 KotH. Dont' worry, about sending a CB Jul 12 07:30:14 CV Jul 12 07:30:18 we can't afford you anyway. Jul 12 07:30:22 ^^' Jul 12 07:30:27 * KotH is not that expensive Jul 12 07:30:35 given i'm paid in chocolate and the job is fun Jul 12 07:30:48 we have the *best* chocolate factory, just 10km away Jul 12 07:31:00 mrpackethead: where in nz are you? Jul 12 07:31:11 mrpackethead: i know it.. got a sample of that a couple of months ago Jul 12 07:31:19 Pauatahanui Jul 12 07:31:23 mrpackethead: or what they market as "as good as swiss chocolate" Jul 12 07:31:39 KotH: what brand was it Jul 12 07:31:44 mrpackethead: did taste nearly exactly as one brand of ours... Jul 12 07:32:10 http://www.whittakers.co.nz Jul 12 07:33:57 mrpackethead: whittakers creamy milk Jul 12 07:35:11 the factory is across the harbour from us Jul 12 07:35:41 the stack comes to life! Jul 12 07:36:35 idle bbb, doe'nt really use much power Jul 12 07:36:50 0.04A @ 24.0V Jul 12 07:38:03 mrpackethead: tastes nearly exactly the same as http://www.chocolatfrey.ch/de/produkte/milch-extra/285/3 Jul 12 07:38:18 mrpackethead: with one difference: the whittakers has a bitter aftertaste Jul 12 07:38:22 so, the good news, if you come out here.. Jul 12 07:38:29 you can get some resonable chocolate Jul 12 07:38:36 ha ha Jul 12 07:38:38 mrpackethead: and the whittakers is probably more expensive as frey is the cheap chocolate in .ch :) Jul 12 07:39:01 They make a 70% cocoa, which is more to my liking Jul 12 07:39:08 with some good coffee Jul 12 07:39:46 https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-prn2/971837_10151725976367661_291443902_n.jpg Jul 12 07:39:50 hey, it works! Jul 12 07:40:12 what does it do? Jul 12 07:40:17 beside blinking leds Jul 12 07:40:36 theres a 24V-5VDC regulator Jul 12 07:40:42 that back feeds all the capes and BBB Jul 12 07:40:55 got a BCC FPGA cape, and an audio cape in there Jul 12 07:41:09 and a break out for four universes of DMX Jul 12 07:41:24 https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-ash4/255039_10151725872937661_2005671035_n.jpg Jul 12 07:41:29 theres a closer look Jul 12 08:00:25 whats a nice way to hardware force a beagle bone to shutdown. Jul 12 08:07:43 push the power button for 5 seconds Jul 12 08:07:57 that will shutdown the pmic Jul 12 08:08:05 but beware Jul 12 08:08:12 you can only turn it on again with the powerbutton Jul 12 08:08:29 Im jsut thinkng about orderly shutdowns Jul 12 08:08:39 and where 'powerbutton' read 'powerbutton or the powerbutton pins on the expansion' Jul 12 08:08:52 the powerbutton gives a KEY_POWER event to the kernel Jul 12 08:09:21 so it you just press it userspace can initiate a shutdown Jul 12 08:24:53 I don't know why I bother with the beagle mailing list, it infuriates me; but I also can't stand people being so blatantly wrong on the internet! _the dilemma_ Jul 12 08:25:53 * dm8tbr hands jackmitchell a family pack of chill-the-f*ck-out pills ;) Jul 12 08:27:11 jackmitchell: you can always browse some rpi forums to calm down Jul 12 08:27:16 * jackmitchell hasn't had his caffeine yet Jul 12 08:32:42 jackmitchell: can we help Jul 12 08:33:24 WHAT? Somebody's *wrong* on the Internet? Call the papers! Jul 12 08:34:32 * vvu hides Jul 12 08:35:00 * mrpackethead aark Jul 12 08:35:08 who. Jul 12 08:35:13 mark this day.

Jul 12 09:19:36 linus is a myth Jul 12 09:19:56 I thought it was only populated with googlebots Jul 12 09:20:38 g+ communites are not the solution either Jul 12 09:21:12 they aren't. and they are a b*tch to filter in gmail :( Jul 12 09:45:04 wow, apple has its own utf8 Jul 12 09:45:58 uh, then it's not utf8 Jul 12 09:46:04 it is Jul 12 09:46:09 utf-8, UTF8 or UTF8 ? Jul 12 09:46:13 but they store stuff in the filesystem as decomposed Jul 12 09:46:19 wtf8 Jul 12 09:46:25 hell Jul 12 09:46:30 huh? Jul 12 09:46:47 ...For example, an Á (A acute) can be encoded either precomposed, as U+00C1 (LATIN CAPITAL LETTER A WITH ACUTE), or decomposed, as U+0041 U+0301 (LATIN CAPITAL LETTER A followed by a COMBINING ACUTE ACCENT). Precomposed characters are more common in the Windows world, whereas decomposed characters are more common on Apple platforms.... Jul 12 09:46:51 this stuff has been misnamed from the beginning Jul 12 09:47:04 ...For example, HFS Plus converts all file names to decomposed Unicode... Jul 12 09:48:14 they call that utf8-mac Jul 12 09:48:24 the mistake was adding the latin1 charset as separate codepoints Jul 12 09:48:45 wasnt that to be compat with some codepage? Jul 12 09:48:56 it's not Jul 12 09:49:16 they are still multibyte characters Jul 12 09:49:52 WTF8 Jul 12 09:50:12 hah, someone made it already :( Jul 12 09:53:00 mru: what do you mean? Jul 12 09:53:14 Á should not be a code point? Jul 12 09:53:19 or Ä? Jul 12 09:54:19 there should not be multiple ways of encoding the same character Jul 12 09:54:49 well, A could be / + \ + - Jul 12 09:55:21 so either use combining diacritics only or add codepoints for _every_ conceivable combination Jul 12 09:55:35 the latter is not realistic Jul 12 09:56:17 but the French and the Germans would argue very much that Á or Ä are a character Jul 12 09:56:49 well, one could decompose all the chinese and other asian scripts too Jul 12 09:56:54 would make for far less chars Jul 12 09:58:04 and you would shift the burden of composition/decomposition to everybody Jul 12 09:58:21 not realistic for widespread adoption, as "clean" as it might be Jul 12 09:59:30 hi, does the beaglebone black have a RTC? Jul 12 10:00:58 av500: world was young when we only had ASCII Jul 12 10:01:16 ant_work: there never was such a world Jul 12 10:01:33 dnai23: no Jul 12 10:03:55 dnai23: yes, but no battery, so practically speaking av500 is right Jul 12 10:05:25 well, then implementations should be required to normalise the encoding before sending/storing Jul 12 10:07:31 mru: normalise how? Jul 12 10:08:16 ant_work no EBDIC? Jul 12 10:08:31 make sure things like á are only ever stored one way Jul 12 10:08:51 disambiguate Jul 12 10:12:56 koen: and it's not possible to connect a battery? No pins for that? Jul 12 10:16:10 dnai23: there is no useful RTC on teh BBB Jul 12 10:16:18 you have to add / create one Jul 12 10:16:27 why is there a useless RTC on BBB ? Jul 12 10:16:49 because Jul 12 10:17:21 no more money after bailout ? Jul 12 10:17:23 because there is'nt. Jul 12 10:17:56 im using a DS3231 on the i2c bus Jul 12 10:18:05 backed up with 3V lithium Jul 12 10:23:45 the 3231 is useful beucase its temp compensated, has an internal xtal and is supported by the kernel Jul 12 10:23:51 so, its an easy option. Jul 12 10:24:00 kk thx :) Jul 12 10:42:04 does anyone here have orcad pcb design software? Jul 12 10:42:45 nope Jul 12 10:42:53 I once had the DOS version Jul 12 10:43:03 25ys ago :) Jul 12 10:43:08 Hi guys Jul 12 10:44:05 Im wanting to convert the BBB design files into Eagle Jul 12 10:44:35 have you tried orcad =chinese=> eagle ? Jul 12 10:44:43 hi guys cant u tell me how to clear the uart rx n tx buffer in BBB Jul 12 10:44:49 das what? Jul 12 10:45:04 mrpackethead: I was trolling Jul 12 10:45:15 i want to clear the RX buffer in BBB Jul 12 10:45:18 and I ruined it by mentioning it :( Jul 12 10:45:40 av500 u ther? Jul 12 10:46:05 vin_, tcflush() Jul 12 10:46:28 ok thanks will try it panto Jul 12 10:46:36 如果翻译成普通话首先是有帮助的 Jul 12 10:46:37 我能做到这一点 Jul 12 10:47:47 lachen heraus laut Jul 12 10:48:01 das, i dont' speak that Jul 12 10:48:04 panto wat parameters to pass in tcflush()?? Jul 12 10:48:33 to clear the tx n rx buffer Jul 12 10:48:33 man tcflush Jul 12 10:48:34 man tcflush Jul 12 10:48:55 didnt get you sir.? Jul 12 10:49:08 哈哈 | lol | lachen heraus laut Jul 12 10:49:09 use a unix host Jul 12 10:49:13 http://linux.die.net/man/3/tcflush Jul 12 10:51:02 got it guys... Jul 12 10:51:37 just want to know the value of int tcflush(int fd, int queue_selector); queue \_selector to be put to clear it?? Jul 12 10:54:34 thanks sir got it working Jul 12 10:55:12 I see panto applied the man-hammer Jul 12 10:56:19 av500, sounds dirty as you phrase it Jul 12 10:59:05 [kernel] koenkooi pushed 1 new commit to 3.8: http://git.io/Yxv2QA Jul 12 10:59:06 kernel/3.8 d9c49a7 Koen Kooi: 3.8: add PRU rpmsg driver, fix ADC mapping... Jul 12 11:26:47 Hm, I wonder how could I interpret this statement? :) "Once you purchased devkit, you also have right for the license of the source code." - I've asked manufacturer for license terms of their firmware source code and this is the reply I've got. Does it mean, that it's kind of a public domain? :D Jul 12 11:27:47 license to "use " the code Jul 12 11:28:36 sure, my "use" case is opensource compliant product Jul 12 11:29:20 I didn't signed NDA or any crap like that, they don't even forbid any redistribution of their documentation, there's just small note "do not reproduce without written permission" Jul 12 11:30:10 well, IANAL... Jul 12 11:34:03 this is disclaimer from the docs where the registers are described "© 2008 XYZ, Inc. All rights reserved. The reproduction of this document is NOT allowed without approval of XYZ, Inc." Jul 12 11:34:36 it could be interpreted in a way, that I'm allowed to create C header with description of this registers publicaly available, right? Jul 12 11:37:29 ynezz, you can't copyright facts Jul 12 11:37:37 such as register addresses Jul 12 11:37:59 you can copyright an implementation of writing them down in a pretty table, though Jul 12 11:38:19 so just don't make your table look like the table in the doc, make your table be C code :) Jul 12 11:38:27 but ianal Jul 12 11:38:37 I also didn't stay in a holiday inn express last night Jul 12 11:38:51 sure, but you've to describe the registers somehow Jul 12 11:39:00 jackmitchell: another thing I'd noticed is that people ask here for help, we give them the solution and a while later they post to the list Jul 12 11:39:05 jackmitchell: that just weirds me out Jul 12 11:39:21 they post the help to the list? Jul 12 11:39:33 no, the original question Jul 12 11:39:40 koen: heh yeah; quite often get dejavu like that Jul 12 11:39:43 ynezz, calling something its name isn't copyrightable either, in itself Jul 12 11:40:09 good point Jul 12 11:40:09 if you describe the thing the exact same way the data sheet does, then you're getting closer to an issue Jul 12 11:40:17 like if you write a paragraph for each register Jul 12 11:40:29 I suppose they ask in here, get an answer that is too hard or not what they wanted, so post to the list in a desperate attempt to get another answer, or someone to post #exactsteps Jul 12 11:40:32 just using one or two words that match what the data sheet says isn't copyright infringement Jul 12 11:40:35 but you usually have "reproduction of document and/or parts" wording Jul 12 11:40:58 ynezz, just don't distribute the document yourself in its exact form and you're fine Jul 12 11:41:07 if you're writing code using register names you have nothing to worry about Jul 12 11:41:20 all TI data sheets and user manuals are copyright Jul 12 11:41:39 linux is full of the same names used in the data sheets Jul 12 11:42:22 Anybody here know someone @ti.com I can contact about CC3000 part? Jul 12 11:42:53 KotH, ka6sox, ^^^ do you know? Jul 12 11:43:19 apparently all TI engineers keep leaving for greener pastures Jul 12 11:43:42 you hit some bug in cc3k? Jul 12 11:43:45 :p Jul 12 11:43:57 ynezz, another engineer I work with is throwing cc3000 dev kits at walls Jul 12 11:44:02 screaming Jul 12 11:44:04 :D Jul 12 11:44:10 you know? Jul 12 11:44:35 nope, just been reading it's source code yesterday Jul 12 11:44:56 aparently example code for the CC3000 works just as well as sample code for all other TI parts... Jul 12 11:45:45 bradfa: I know some TI sales people thay tried to sell is to us Jul 12 11:53:13 thanks, av500! :) screaming is subsiding slightly for the time being Jul 12 11:54:52 bradfa: hmm... not really Jul 12 11:55:04 bradfa: i usually go past our local sales when i have questions about specific parts Jul 12 11:55:12 bradfa: they then forward me to the respective engineer Jul 12 11:55:55 KotH, we were trying that but we work through Avnet for most of our buying and their FAE for TI has been less than stellar lately Jul 12 11:56:10 bradfa: conntact ti sales directly Jul 12 11:56:20 KotH, yes, that's next step Jul 12 11:56:23 thanks! Jul 12 11:56:37 bradfa: we useally buy from farnel/mouser/msc, but send questions to the ti sales Jul 12 11:56:46 usually* Jul 12 11:57:15 KotH, I don't think we've got a contact at TI directly for sales but av500 gave some names associated with CC3000 so we're gonna try screaming at them next Jul 12 11:57:27 bradfa: also an idea Jul 12 11:57:45 TI documentation is as good as always for CC3000 Jul 12 11:57:51 bradfa: and dont worry about volumes. we are one of the very small companies they sell to, but they have been very helpfull nonetheless Jul 12 11:57:58 k, good to know Jul 12 12:02:40 ah, rday is playing obtuse again Jul 12 12:05:18 he reminds me of a slightly more informed LKCL Jul 12 12:05:39 ARGHH! A datasheet in FRENCH! Jul 12 12:05:40 ^^; Jul 12 12:06:04 maybe it is french data Jul 12 12:06:22 av500: lpa** ! Jul 12 12:06:57 playing fair Jul 12 12:07:04 ok, so it is a documentation problem only. Jul 12 12:08:32 sure, it's never silicon problem Jul 12 12:10:09 rs485, what is suppose to give an enable signal;? Jul 12 12:10:55 http://www.lvr.com/rs-485_circuits.htm Jul 12 12:12:23 change the direction? Jul 12 12:15:45 R2E4: only one device may drive the RS-485 bus at any time Jul 12 12:16:03 R2E4: hence you have to be able to control the time when you send, which you do by using the enable signal Jul 12 12:17:54 R2E4: oh.. and forget that circuit with the 555, control the enable directly by the uC/uP that does the transmit Jul 12 12:20:27 or use a 4 wire bus and hardwire it Jul 12 12:21:46 there is a name for that: RS-422 Jul 12 12:22:12 one particular implementation is very well known: appletalk Jul 12 12:35:10 Hello, need assistance about RTC on Beaglebone Black, please ... Can someone help me? Jul 12 12:35:14 * panto 's first work on a bus was on a serial multi drop bus Jul 12 12:35:36 totally hacked out way to communicate with a bunch of HC05's Jul 12 12:37:42 panto: huh? the HC05's contained a whole section how to do that in their databook Jul 12 12:38:18 Bels: RTC on BBB was discussed 2 hours ago, check the logs Jul 12 12:38:44 KotH, yes, but the protocol running on top was custom Jul 12 12:39:12 * KotH shudders Jul 12 12:39:23 i had enough "custom protocols" for a life time Jul 12 12:39:38 it was 1995-1996 Jul 12 12:39:55 that might be an excuse, but it is no reason at all Jul 12 12:40:37 it was a time when using a C compiler was cutting edge Jul 12 12:40:51 the slave boards were HC05's the controller was HC11 Jul 12 12:56:46 Emmmm Jul 12 12:57:29 mrpackethead: Idiot Jul 12 12:57:45 we know it's you andrew ... Jul 12 12:57:57 Lol Jul 12 12:58:09 Yup Jul 12 13:01:40 dont' tell us you are attached to that nickname and you feel sorry to change Jul 12 13:02:12 (someone did, must be a new trend) Jul 12 13:09:13 LetoThe2nd, got the post-card Jul 12 13:09:16 that was nice :) Jul 12 13:09:16 Hey guys, Im kinda new to beagle board, I now know how to program arduino. But I have a couple of questions Jul 12 13:09:47 panto: :) Jul 12 13:09:49 lardeshwarao: just think of the beagle as a linux computer. that brings you already 90% there Jul 12 13:10:33 panto: jsut met another athenoid on tuesday... robert berger was in munich for a couple of beers :) Jul 12 13:10:47 oh thanks dm8tbr Jul 12 13:11:06 in arduino there are shields, are there shields in beagle boards? Jul 12 13:11:26 Assuming it is a microcontroller Jul 12 13:11:37 . Jul 12 13:12:07 lardeshwarao: there are 'capes' that are very similar to shields. those are for the BeagleBone devices Jul 12 13:12:15 lardeshwarao: for the beagle_BONE_ there are so-called capes, but it is _not_ a "microcontroller" in the arduino sense. Jul 12 13:12:30 there's the pru... Jul 12 13:12:37 LetoThe2nd, hehe Jul 12 13:12:38 note, that the beagle is much more powerful than a microcontroller. as I said, linux computer. Jul 12 13:12:41 I should give him a call Jul 12 13:12:58 Oh, but is it possible to program it as a microcontroller using the I/O pins? Jul 12 13:13:20 What programming does beagle bone use? Jul 12 13:13:23 lardeshwarao: theoretically yes, practically no, under linux things work differently Jul 12 13:13:47 you don't have to run linux... Jul 12 13:14:02 mru: you can also walk or swim it, yes ;) Jul 12 13:14:09 panto: :) Jul 12 13:14:19 Oh so do you guys know any good sites for beginners? Jul 12 13:14:25 google Jul 12 13:14:33 thanks mru..... Jul 12 13:15:01 lardeshwarao: the beagleboard group on G+ has lots of getting started "tutorials" and "videos" ;) Jul 12 13:15:17 LetoThe2nd: he asked for good Jul 12 13:15:23 a.k.a. see this clip of my first JS pin toggling ;) Jul 12 13:15:30 mru: not for god? Jul 12 13:16:25 Oh ok thanks Jul 12 13:16:40 I will def look into it Jul 12 13:16:52 LetoThe2nd: well, that would be you Jul 12 13:18:40 mru: i would be one amongst a variety of choices. Jul 12 13:18:52 * dm8tbr toggles LetoThe2nd's credit card PIN with some JS Jul 12 13:19:24 * LetoThe2nd doubst that JS can handle such simple things as a couple of numbers in a string. Jul 12 13:19:29 is it possible to bitbang money if you don't have any of the real stuff? Jul 12 13:19:43 I wish Jul 12 13:19:51 mru: that's called "mining" these days Jul 12 13:20:04 KotH: wasn't it always? Jul 12 13:20:27 I have 2.5LTC for sale btw Jul 12 13:20:48 pan handling is pretty close to bit banging for money Jul 12 13:20:58 das__: how much would that be in gold pressed latinum? Jul 12 13:22:49 LetoThe2nd: I thought you preferred spice Jul 12 13:23:07 LetoThe2nd: that'd be about 31.5 Jul 12 13:23:10 or 1 art Jul 12 13:23:34 mru: are you messing me up with the guild? Jul 12 13:27:21 anyways, worktime is over. have a nice {troll,fri}day everybody Jul 12 13:27:34 Already? Jul 12 13:27:43 later Jul 12 13:28:10 he either lives in the future or in germany Jul 12 13:28:10 KotH: what schematic capture do use. Jul 12 13:28:18 Guest7896: altium designer Jul 12 13:28:32 Guest7896: not the best, but good enough Jul 12 13:28:34 Mmm. Jul 12 13:28:41 Guest7896: but i would probably choose something different these days Jul 12 13:28:51 Like? Jul 12 13:28:56 KotH: I thought you draw it by hand with liquid chocolate? Jul 12 13:29:15 liquid chocolate? what kind of abomination and abuse is that? Jul 12 13:29:30 heat does that to it Jul 12 13:29:47 unless you prefer the "cold pressed" variety Jul 12 13:30:07 Guest7896: cadstar from zuken seemed to be quite nice Jul 12 13:30:20 Guest7896: if you have money, go for cr-5000 Jul 12 13:30:44 av500: latinuum pressed chocolate, please Jul 12 13:31:38 I want to stea Jul 12 13:31:41 Guest7896: the thing is, altium is these days in a price region, where the old expensive cad/eda tools aren't that much more expensive anymore Jul 12 13:31:52 Guest7896: and they are quite a bit better Jul 12 13:31:52 av500: is chocolate like olive oil in that sense? Jul 12 13:32:19 Guest7896: hint: what will be really expensive is the schematic and layout symbol libraries. either you get some that you can trust, or you have to draw each one yourselves Jul 12 13:32:54 I want to take the bbb design files and use them as a basis for a new project Jul 12 13:32:56 symbol libraries... :| Jul 12 13:34:06 Guest7896: if you give me an email, i can give you some info i got from zuken on pricing and stuff Jul 12 13:34:32 Guest7896: then cadstar might not be a bad idea, it has quite a few import filters Jul 12 13:36:03 Guest7896: commercial or hobby? Jul 12 13:36:14 Commercial Jul 12 13:36:15 av500: same difference for Guest7896 :-) Jul 12 13:36:42 Av500 it's mrpackethead here Jul 12 13:36:48 On iPad. Jul 12 13:36:53 lol Jul 12 13:37:19 ok Jul 12 13:37:46 I'd love to just suck the orcad into eagle Jul 12 13:38:05 write a little perl script Jul 12 13:38:53 Guest7896: oh.. i have an orcad for dos at home, full license including dongle Jul 12 13:39:25 but do you have a printer port? Jul 12 13:41:12 There is a export format apparently that can be read by eagle Jul 12 13:41:13 someone could make a parallel port cape Jul 12 13:41:29 * dm8tbr did some funky stuff in the past... virtual machine, pci-lpt card, export port to virtual machine Jul 12 13:41:32 suihkulokki: they did. Jul 12 13:41:33 and it actually worked Jul 12 13:41:48 mru: i still have computers that have a printer port :) Jul 12 13:41:52 managed to retire some old P2 machine and replace it with a P4 at that time Jul 12 13:41:57 Every good geek has a computer hardware junk yard in their basement, right? Jul 12 13:42:03 no Jul 12 13:42:13 these days I throw it all away Jul 12 13:42:14 Oh... guess Im special Jul 12 13:42:16 in case of av500 it's next to his desk ;) Jul 12 13:42:22 only EVMs Jul 12 13:42:31 I dont keep old PC parts any more Jul 12 13:42:40 ah Jul 12 13:42:41 I found that I dont ever really use them for anything Jul 12 13:42:48 av500: Is there a 12 step program for this? Jul 12 13:42:50 I have a pile of old PCs Jul 12 13:42:52 KotH: Thanks, sorry, didnt see tyour post earlier. Jul 12 13:43:02 dm8tbr: they have e-waste boxes here now Jul 12 13:43:06 it's starting to get hard to move in my room Jul 12 13:43:07 next to the glass containers Jul 12 13:43:14 fit a whole PC in the slot Jul 12 13:43:15 how convenient! Jul 12 13:43:17 yes Jul 12 13:43:25 we *filled* one last week Jul 12 13:44:21 I found a mouse living in a Pentium. Probably time for it to go, eh? Jul 12 13:44:27 for the mouse? Jul 12 13:44:32 yeah :) Jul 12 13:44:40 no, both Jul 12 13:44:42 replace it with a trackball ;) Jul 12 13:44:48 dm8tbr: I did Jul 12 13:45:03 yeah, we know your magic 8-ball Jul 12 13:45:53 I was going to get a trackball, then I remembered I have a wrist. Jul 12 13:46:32 how inconvenient Jul 12 13:47:37 KotH: could u try an export? Jul 12 13:49:34 * av500 feels plagued Jul 12 13:53:11 * dm8tbr wonders if it eventually will evelove into die_Plage Jul 12 13:54:24 or the correct term: Purpurpest Jul 12 13:54:58 that exists: http://en.wikipedia.org/wiki/Purpura Jul 12 13:55:03 NSFWS Jul 12 14:08:06 av500, happy to report Avnet is now scrambling as their TI FAE looks pretty bad when we complain to your contacts plus a few other US TI people :) Jul 12 14:08:18 screaming here has stopped and is turning to laughter at Avnet reactions Jul 12 14:13:09 bradfa: :) Jul 12 14:15:42 does anyone know in a scenario where external signal triggers an edma transfer from a register to the ddr3 what may be the maximum throughput ? Jul 12 14:23:11 Hello, I'm working on a beagleboard-xM and I'm trying to read the user button through /sys/class/gpio/ but I have a couple of issues... Jul 12 14:24:24 more specifically, the rev.C should have the GPIO4 connected to the user button, but apparently the resource is busy and I can't seem to find who is using it Jul 12 14:50:16 moo Jul 12 14:54:15 morning everyone Jul 12 14:54:25 * m_billybob waves Jul 12 14:55:30 is it normal to a BBB take 4 to 5 times longer to boot when ethernet is unplugged? Jul 12 14:55:51 sounds like dns lookups failing Jul 12 14:56:05 and with that said: a good evening everyone Jul 12 14:56:06 gui_: and dhcp timeout Jul 12 14:56:11 the default dhcp timeout is 1minute Jul 12 14:56:22 this day and age, ethernet is a human right Jul 12 14:57:07 well... why couldn't ubuntu resolve DHCP issues after booting? Jul 12 14:57:34 ask #ubuntu Jul 12 14:58:38 just did Jul 12 14:59:26 happy friday everyone Jul 12 14:59:37 gui_: disable eth0 on boot and it will fix that Jul 12 15:00:08 so, timeout is most likely to be the problem. However, it feels that either: (a) timeout is set to 2 min (or more than 1) (is it even possible) Jul 12 15:00:18 (b) there's something else delaying it Jul 12 15:00:35 dmesg Jul 12 15:00:37 no maxinux, I want to use ethernet Jul 12 15:00:51 gui_: then staticlaly configure it :) Jul 12 15:00:54 I'm just wondering why it was taking so long Jul 12 15:00:59 its the dhcp timeout Jul 12 15:01:00 dmesg Jul 12 15:01:00 fix it Jul 12 15:01:10 static assign ip will take care of it Jul 12 15:02:24 no need to fix Jul 12 15:02:37 I just wanted to know the reason Jul 12 15:02:58 gui_, or get a network daemon that doesn't stall the boot Jul 12 15:03:02 thanks for explaining Jul 12 15:09:15 Narf!

Jul 12 15:25:09 that joke was made before Jul 12 15:25:28 you could always make a BeagleBone Cyan by colouring it Jul 12 15:25:31 must have been my other alias Jul 12 15:25:38 sorry i didnt read the manual at all. but it worked yesterday. Jul 12 15:25:44 bugle bone black...it literally blows Jul 12 15:27:02 what about a robotic prothetic leg Jul 12 15:27:24 for professional surfers who may have lost a leg Jul 12 15:28:02 or you could make a prosthetic Arm Cortex8 Jul 12 15:28:37 someone didn't wait the 2.5h for beer time apparently Jul 12 15:29:12 no sir Jul 12 15:29:38 I think I will just turn my beagle bone into an over engineered heating blanket Jul 12 15:30:21 bonos could you boot now? Jul 12 15:32:24 no it doesnt start with holding boot button switching on nor reset or on button Jul 12 15:33:54 no light shines except for power led Jul 12 15:34:10 hmm Jul 12 15:34:52 so it might be trying to boot from the SD, which is good, but your setup might not be ok Jul 12 15:35:09 which system are you using? Jul 12 15:36:44 linux Jul 12 15:37:11 no feces, sherlock Jul 12 15:37:11 ok the lights do shine now but hdmi output not on screen Jul 12 15:37:25 do you have a keyboard plugged? Jul 12 15:37:42 no Jul 12 15:37:58 serial cable? Jul 12 15:38:55 i read sometimes i have to wait several minutes but just while installing newos?

Jul 12 15:51:35 Qt on BBB question... Jul 12 15:51:48 k shoot Jul 12 15:52:16 Want to run a Qt app and have it display on HDMI output... to the desktop essentially. Jul 12 15:52:47 That is to say... no LCD or TFTP. Jul 12 15:53:22 Tried app -display:0 but no joy. ;) Jul 12 15:56:37 av500: hey i need a recommendation on a guinea pig to do some testing Jul 12 15:56:52 av500: if you know anyone that has experience with arduino and has a bbb give me a shout Jul 12 15:57:10 stupid, are you trying to run the command from the serial terminal? Jul 12 15:57:25 nope... at the command line in the desktop env Jul 12 15:57:34 perhaps it installs ubuntu? no its another system....johnny? Jul 12 15:57:51 using an xterm and an external keyboard? Jul 12 15:58:01 How do I set up vnc on my beaglebone black? Jul 12 15:58:12 do you mean you're connected via ssh or something? Jul 12 15:59:04 Yeah I'm connected by ssh. Jul 12 15:59:10 Well over usb. Jul 12 15:59:15 And I want vnc. Jul 12 15:59:44 I was talking to the other guy Jul 12 15:59:49 Oh sorry Jul 12 16:00:08 what's wrong with the howtos of installing vnc? Jul 12 16:00:20 there's nothing different than what your linux box does Jul 12 16:01:09 Is there a howto on how to do it on the BBB? It isn't connected to the internet, but it's on ssh over usb. Jul 12 16:01:36 Re: VNC - we do it this way... Your milage may vary... I HAVE A QUESTION BUT WILL RESPOND TO THIS Jul 12 16:01:46 INSTEAD Jul 12 16:01:54 stupid, export XAUTHORITY=`ls /var/run/gdm/auth-for-root-*/database` ; export DISPLAY=:0.0 Jul 12 16:02:19 on your host... like ubuntu - thanks will try that... back to answering other Jul 12 16:02:39 VNC - on your host... like ubuntu... Jul 12 16:02:52 1. install xtightvncviewer Jul 12 16:03:36 2. copy the Qt4 plugins to the target rootfs to enable frame-buffer VNC operations Jul 12 16:04:12 3. $HOME/oe/arago-tmp/work/armv5te-arago-linux-gnueabi/\ qt4-embedded-4.7.2-r29.0-arago7/image/usr/lib/\ qtopia/plugins/gfxdrivers Jul 12 16:05:01 3. the files you are interested in are libqgfxvnc.so and libqscreenvfb.so Jul 12 16:05:25 4. copy those files to target /usr/lib/qtopia/plugins/gfxdrivers Jul 12 16:06:42 5. on the target... export QWS_SIZE=800x400 (your size may be different) Jul 12 16:06:43 Woah Jul 12 16:07:06 6. then run app... ./applicationName -qws -display VNC:0 Jul 12 16:07:13 Uhm. My board isn't recognizing the usb wifi thing I'm using. Jul 12 16:07:19 7. go to your host machine... Jul 12 16:07:41 And the light on it isn't flashing. Jul 12 16:08:39 8. start the vncviewer application... vncviewer -x11cursor Jul 12 16:09:07 9. oppps provide vncviewer app (little bity dialog) with the target ip address. Jul 12 16:09:13 9. viola Jul 12 16:09:48 its a usb key Jul 12 16:10:07 Hi Jul 12 16:10:50 please, where to buy beaglebone boards in spain??? Jul 12 16:11:38 anybody know this? Jul 12 16:11:56 perhaps my hdmi adapter has a defect now....?!! Jul 12 16:12:19 pablo at ebay around the world Jul 12 16:13:39 ok, but beaglebone have distributors in spain? Jul 12 16:13:47 thanks Jul 12 16:15:28 read about us ... all i really know is they dont care about us (M Jackson) Jul 12 16:16:03 What the hell is happening? I have my usb hub plugged in and a usb dongle plugged into that but it's not being recognized. Jul 12 16:16:21 And the light on the usb is off. Jul 12 16:18:03 panto... both variables are and have been exported from the beginning... no joy still. Jul 12 16:18:34 what about a single xterm? Jul 12 16:19:04 <_av500_> pablo_: check the website Jul 12 16:19:19 Anyone? Jul 12 16:19:20 <_av500_> it lists distributors Jul 12 16:19:28 I'm really annoyed. Jul 12 16:19:38 Why would it not be powered? Jul 12 16:20:09 willdude use a powered one Jul 12 16:21:10 I have a powered hub. Jul 12 16:21:25 And it's powered/ Jul 12 16:21:32 panto... using built in console thingy... invoking xterm pops up xterm with no wmanager controls and freezes all graphics. ;( Jul 12 16:21:50 my screen is completely black yes, its a beaglebone BLACK isnt it? Jul 12 16:21:59 is that angstrom or ubuntu again? Jul 12 16:22:08 angstrom Jul 12 16:22:16 06-20 image. Jul 12 16:22:26 hub Jul 12 16:23:22 Arrrgh Jul 12 16:23:41 Lsusb lists two hubs. Jul 12 16:23:50 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Jul 12 16:23:52 Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Jul 12 16:25:16 <_av500_> one can never have enough hubs Jul 12 16:26:03 Argh I'm so annoyed. Jul 12 16:26:11 Why the hell is it not working? Jul 12 16:29:25 use a powered usb hub why cant i see anything? Jul 12 16:30:40 cause its a split hub design and the support for that is funky Jul 12 16:31:03 I do use a powered usb hub. Jul 12 16:31:19 And it isn't being recognized. Jul 12 16:31:39 Ahah Jul 12 16:32:01 what the hell is broken perhaps i ask avril lavigne aarrghhhh Jul 12 16:32:05 The usb to pc connection can't provide enough ampage to even run the usb post. Jul 12 16:32:16 *host Jul 12 16:32:18 lol Jul 12 16:34:46 500 mA should be enough for anybody, "reworded Bill Gates Quote" Jul 12 16:35:00 Except it isn't. Jul 12 16:35:16 I think you have a crappy hub Jul 12 16:35:21 Must pop to maplin and buy a proper one. Jul 12 16:35:26 *supply Jul 12 16:35:32 I need a proper power supply. Jul 12 16:35:40 yeah Jul 12 16:35:49 oh ihad 2 from china1 is broken Jul 12 16:36:05 Because when the BBB is powered with the 5v supply from the hub, it can run the wifi dongle just fine. Jul 12 16:36:21 my board should be here by today or tomorrow so I'll initially power it with my bench seupply and get a semi accurte current reading Jul 12 16:36:35 yes BBB ihave on micro sd Jul 12 16:37:16 How can I use puttty for ssh to bbb? Jul 12 16:37:25 Is it port 22? Jul 12 16:37:32 if you are running a usb device and getting power from the usb plug you cant supply the full 500mA Jul 12 16:37:57 unless you changed it Jul 12 16:38:02 22 default Jul 12 16:38:35 if your wifi dongle is thirty then its going to droop the power Jul 12 16:39:03 This could be fun, installing usb wifi drivers over ssh. Jul 12 16:39:36 ifdown wlan0 Jul 12 16:39:38 damn Jul 12 16:40:05 do i have to press on button for getting hdmi output? the lights do shine now. Jul 12 16:40:27 I've done the ifdown on a remote location before and forgot to add the ;ifup, long drive Jul 12 16:41:18 when we designed system for phase 2 added remote serial Jul 12 16:41:36 So how do I make my wifi dongle work? It recognizes it, and knows the model/ Jul 12 16:42:05 first you need the 5V from an adpater Jul 12 16:42:34 so you can supply 500mA to usb host and current required for the system Jul 12 16:43:27 since I jumped into your sandbox late WildDude: sorry if I missed some details Jul 12 16:44:07 but I think your wifi dongle is drooping the power once it starts to go into its full on state Jul 12 16:44:54 and its becuase you are getting the power from the usb upstream Jul 12 16:46:15 most decent usb hubs have an IC that has an overcurrent pin. This pin is connected to some other chip that then sends the disable to the ICs enable pin Jul 12 16:46:45 you may be experiencing that Jul 12 16:47:43 Hmm. Jul 12 16:48:03 I have an RTL8187 based dongle. Jul 12 16:48:50 so are you powering the BBB via the usb Jul 12 16:49:14 what should i do? cry like a wolf? Jul 12 16:49:18 No Jul 12 16:49:24 5v power supply. Jul 12 16:49:42 what is the 5V current rating Jul 12 16:49:48 on the wll wart Jul 12 16:50:03 2a Jul 12 16:50:12 you is screwed LOL Jul 12 16:50:20 I think. Jul 12 16:50:30 it says it Jul 12 16:50:33 should Jul 12 16:50:48 2A is plenty of headroom Jul 12 16:51:00 the bbb uses http://www.ti.com/lit/ds/symlink/tps2051.pdf Jul 12 16:51:13 So it's okay then? Jul 12 16:51:15 for its IC to signal overcurrent Jul 12 16:51:23 yeah 2A is plenty Jul 12 16:51:28 Right. Jul 12 16:51:45 So how the hell do I install the drivers with no internet? Jul 12 16:52:08 that gives 500mA for usb and 1.5 A max for entire system - efficiency losses Jul 12 16:52:21 debug serial terminal Jul 12 16:52:29 How? Jul 12 16:52:59 hold on I forgot the name gotta google Jul 12 16:53:29 xmodem Jul 12 16:53:35 ymodem or zmodem Jul 12 16:54:15 Ive transferred file using xmodem over sat link so it works Jul 12 16:54:21 So I type xmodem? Jul 12 16:54:28 depends Jul 12 16:54:43 are you using hyperterminal Jul 12 16:54:50 No putty. Jul 12 16:55:24 Can I just check that there are drivers first? Jul 12 16:55:38 ok not sure but If I remember I would start xmodem on my embedded system(beagle variant) Jul 12 16:55:55 yeah you probably need the driver first Jul 12 16:56:15 did you try to just modprobe Jul 12 16:56:25 the dongle Jul 12 16:56:38 Willdude123, have you checked dmesg to see if it is actually recognised at all when plugging it in ? Jul 12 16:57:05 or lsusb Jul 12 16:57:10 idd Jul 12 16:57:36 aeh turn to that station..... connect toa pc drivers from board? Jul 12 16:58:27 Stanto: I checked lsusb that's how I found what chip it was based on. Jul 12 16:58:44 i can send u but sure u have sb for that.... Jul 12 16:59:25 Willdude123, Then if it's detected, and you're using the default angstrum distro, have you tried modprobe-ing the driver for it and/or checking packages for the distro to see if it's in the kernel and/or there's a package for it ? Jul 12 16:59:36 Modprobing? Jul 12 16:59:47 How? Jul 12 17:00:09 http://linux.die.net/man/8/modprobe Jul 12 17:00:25 This actually just worked out of the box on ubuntu on my pc. Jul 12 17:00:26 You'll need to know the name of the driver in angstrum to modprobe it Jul 12 17:00:49 Right. Jul 12 17:00:57 This is so confusing. Jul 12 17:01:10 I know what chip it's based on, and that's all I know. Jul 12 17:01:22 How do I modprobe? I don't understand it. Jul 12 17:02:02 Willdude123, you'll have to do a bit of research then, Jul 12 17:02:39 fyi if you actually need to use xmodem then get terratem Jul 12 17:02:46 term Jul 12 17:02:47 Argh wtf. Jul 12 17:02:55 I'm a noob. Jul 12 17:03:00 I can't help it. Jul 12 17:03:00 thats fine Jul 12 17:03:08 I don't understand any of this shit. Jul 12 17:03:21 ARrgh Jul 12 17:03:22 at least you have the debug serial connected Jul 12 17:03:39 I draw the support line there Jul 12 17:03:59 type this lsusb Jul 12 17:04:11 bunch of noise occurs Jul 12 17:04:16 " Jul 12 17:04:22 paste that to pastebin sned me the link Jul 12 17:04:30 Bus 001 Device 002: ID 0846:6a00 NetGear, Inc. WG111v2 54 Mbps Wireless [RealTek RTL8187L] Jul 12 17:04:43 that's the relevant bit. Jul 12 17:06:52 I saw the relavent bit wilddude Jul 12 17:07:07 now find some relavent stuff in dmesg Jul 12 17:08:01 like try dmesg | grep wlan Jul 12 17:08:34 Nothing returned. Jul 12 17:08:54 ok dmesg | grep the chip name you told me Jul 12 17:09:25 Nope/ Jul 12 17:09:26 i forgot the rt chip you said Jul 12 17:09:29 Nothing. Jul 12 17:09:56 well dmesg | less then eyeball scan it Jul 12 17:10:41 Won't fit on the scrollback. Jul 12 17:10:41 if nothing then less /var/log/syslog eyeball scan Jul 12 17:11:04 that what less if for Jul 12 17:11:09 less is more :) Jul 12 17:12:24 so n00b train the | sends the std out in to the stdin of the command Jul 12 17:13:20 so dmesg spits out chars to the stdout. The pipe | then takes the stdout and connects it to the stdin of the command Jul 12 17:13:59 Ah right. Jul 12 17:14:16 Nothing there. Jul 12 17:14:35 what was the rt chip you said earlier Jul 12 17:14:42 /var/log/syslog doesn't exist. Jul 12 17:14:58 ok angstrom I forget the log on it Jul 12 17:15:09 someone chime in on that Jul 12 17:15:54 anyways repaste the lsusb stuff Jul 12 17:16:09 my connection broke eariler Jul 12 17:16:55 Bus 001 Device 002: ID 0846:6a00 NetGear, Inc. WG111v2 54 Mbps Wireless [RealTek RTL8187L] Jul 12 17:17:39 try this Jul 12 17:17:42 modprobe rtl8187 Jul 12 17:18:01 Nothing. Jul 12 17:18:07 thats perfect Jul 12 17:18:28 when you modprobe and command prompt returns thats good Jul 12 17:18:36 now check dmesg Jul 12 17:18:43 dmesg | grep wlan Jul 12 17:19:50 Shit I took it out and now it doesn't power up. Jul 12 17:19:50 in linux modprobe is same as windows do you wish to install driver -> next next next next next next next next next finish Jul 12 17:19:54 I'll reboot. Jul 12 17:20:18 ok you'll have to run the modprobe again Jul 12 17:20:40 Shoot this is getting really hot. Jul 12 17:20:49 what is Jul 12 17:21:22 hot as in touchable hot or hot as in burnt finger Jul 12 17:21:50 touchable. Jul 12 17:21:56 that aint hot Jul 12 17:22:02 Okay Jul 12 17:22:08 thats just heat dissapation Jul 12 17:22:40 hot is F___ just toughed tip of soldering iron .... again Jul 12 17:22:46 touched Jul 12 17:23:07 Right. Jul 12 17:23:37 anyways do the modprobe rtl8187 Jul 12 17:23:44 then look at dmesg Jul 12 17:23:59 Yep nothing in there. Jul 12 17:24:12 did you modprobe Jul 12 17:24:18 Yup Jul 12 17:24:22 lsmod Jul 12 17:24:30 Ah it's the RT18187L Jul 12 17:24:44 Does that make a difference? Jul 12 17:25:28 Well there is no module for the 'L so I presume not. Jul 12 17:25:34 no modprobe uses the .ko name in the /lib/modules/`uname -a`/blahh Jul 12 17:26:10 http://pastie.org/8135126 Jul 12 17:26:13 but lsmod should show the rt Jul 12 17:26:19 It does. Jul 12 17:26:39 driver installed Jul 12 17:26:49 I can temporarily use ethernet btw, but it's the same one as the PC I'm using uses/ Jul 12 17:26:58 Right now how to connect? Jul 12 17:27:04 so now ifconfig Jul 12 17:27:27 ifconfig hopefully contains wlan0 Jul 12 17:27:52 http://pastie.org/8135128 Jul 12 17:28:17 you almost home Jul 12 17:28:30 now past /etc/network/interfaces Jul 12 17:29:01 What do I do with it? Past? Jul 12 17:29:06 so cat /etc/network/interfaces Jul 12 17:29:10 copy paste Jul 12 17:29:11 Oh paste Jul 12 17:29:23 yeah i think faster than i type Jul 12 17:29:36 No such dir or file. Jul 12 17:30:01 are you running default bbb Jul 12 17:30:15 yup Jul 12 17:30:25 I am waiting on mine so letme google real quick Jul 12 17:30:41 what uname -a say Jul 12 17:31:01 How do you know this when you haven't got one yet? :P Jul 12 17:31:12 Linux beaglebone 3.8.13 #1 SMP Tue Jun 18 02:11:09 EDT 2013 armv7l GNU/Linux Jul 12 17:31:59 Linux user since forever Jul 12 17:32:24 Ah right. Jul 12 17:32:26 it's all the same once you get rid of windows mentality Jul 12 17:32:53 but looking on google you should have na /etc/network folder Jul 12 17:32:58 Windoze is fine for most people.

Jul 12 17:43:55 I use this line $java -jar dacapo-9.12-rc1-bach.jar eclipse > results.txt Jul 12 17:44:49 the lines starting with ==== are the most important, but they are missing in my output file Jul 12 17:46:48 Bash_, try using &> instead of > to redirect both stdout and stderr Jul 12 17:47:15 okay I try that, thank you Jul 12 17:53:53 thank you that worked great. is there a possibility to write it into my text file and to display it in command line at the same time? Jul 12 17:54:21 yeah 2>&1 | tee yourfile.txt Jul 12 17:56:56 laymans terms redirect stderr into stdout then send all that into the tee program which saves stdin into a file and prints to screen Jul 12 18:04:26 $java -jar dacapo-9.12-rc1-bach.jar eclipse 2>&1 | tee results.txt Jul 12 18:05:08 that did not work. I am sorry, I am new to linux I looked up the tee connection and understood what you meant Jul 12 18:05:28 but the >& is still my prob Jul 12 18:06:18 stdout gives me no useful information anyway. Best would be to store in my text file just the stderr Jul 12 18:08:30 that should send both stdout and stderr to tee Jul 12 18:08:54 i just emulated it with echo yoyoyo 1>&2 | cat 2>&1 | tee yo.txt Jul 12 18:09:37 which echoed yoyoyo to the stderr then catted both to stdout then teed it Jul 12 18:09:46 worked fine Jul 12 18:11:59 ya thanks that example worked for me fine as well. I look again into my syntax. My prob is, that it does not execute my dacapo benchmark when I am using $java -jar dacapo-9.12-rc1-bach.jar eclipse 2>&1 | tee results.txt Jul 12 18:12:32 jsarman: Hi again Jul 12 18:12:41 Do I have to start again after a reboot? Jul 12 18:13:02 what is the eclipse for in the java command Jul 12 18:13:17 wildman you have to modprobe again Jul 12 18:13:24 Ok Jul 12 18:13:58 if you want it permanent the just add the driver to /etc/modules Jul 12 18:14:03 Right now where were we?? Jul 12 18:14:14 How? Jul 12 18:14:21 the dacapo benchmark suite offers a couple different benchmarks and expects a command like eclipse, xalan, h2 or tomcat Jul 12 18:15:20 heres a interfaces pastebin http://pastebin.com/t2f943HD Jul 12 18:15:41 oh ok Jul 12 18:16:03 so its just String[] args the args[0] Jul 12 18:16:36 jsarman: how do I find the driver and move it? Jul 12 18:16:43 Also, what do I do from here? Jul 12 18:16:44 what are these commands called like > and &> and 1>&2 so I can look up their help Jul 12 18:16:45 you dont Jul 12 18:16:57 I/O redirection Jul 12 18:17:18 the > | all IO stuff Jul 12 18:17:19 Oh so a symlink? Where is the driver I need to link to? Jul 12 18:17:29 pretty simple after you get it Jul 12 18:17:35 no Jul 12 18:17:45 what was the modprobe again Jul 12 18:18:00 i forgot already Jul 12 18:18:16 okay thank you jsarman :) have a nice weekend Jul 12 18:18:23 modprobe rtl8187 Jul 12 18:18:45 so echo rtl8187 >> /etc/modules Jul 12 18:19:00 Done. Jul 12 18:19:14 so after reboot should be permanent Jul 12 18:19:36 Now how do I set up a network? Jul 12 18:19:48 the pastebin i sent you Jul 12 18:19:52 is a start Jul 12 18:20:05 that'll get your interfaces file Jul 12 18:20:34 then you have to change the my stuff Jul 12 18:20:44 in the wlan0 section Jul 12 18:20:55 maybe you should bring up eth0 first Jul 12 18:20:56 Oh sorry I missed that. Jul 12 18:21:17 can you hook up the ethernet port Jul 12 18:21:45 No Jul 12 18:21:47 have extra eth cable and open port on your router Jul 12 18:21:51 damn you Jul 12 18:22:00 Sorry Jul 12 18:22:03 lol Jul 12 18:22:10 Err Jul 12 18:22:21 Can't find that paste you sent. Jul 12 18:22:33 Ah seen it. Jul 12 18:22:49 http://pastebin.com/t2f943HD Jul 12 18:23:12 So I do vim /etc/network/interfaces and paste that? Jul 12 18:23:28 yeah if you know vi Jul 12 18:23:45 wasn't sure if you spoke vi Jul 12 18:24:32 I use vim but the vim on here is pretty old by the looks of it and messed up/ Jul 12 18:24:47 try :set paste first Jul 12 18:24:50 then i Jul 12 18:24:55 then paste it Jul 12 18:25:34 Nothing pasting to vim atm. Jul 12 18:25:39 Could just wget that. Jul 12 18:25:39 leave out the word first Jul 12 18:25:51 or use nano Jul 12 18:26:16 nano /etc/network/interfaces Jul 12 18:26:45 How to save with nano? Jul 12 18:27:04 im vi guy Jul 12 18:27:13 I think its ctrl W Jul 12 18:27:14 Done. Jul 12 18:27:17 Right. Jul 12 18:27:31 Now I'll reboot. Jul 12 18:27:43 no Jul 12 18:27:50 Oh oops. Jul 12 18:27:55 this is linux my friend Jul 12 18:27:56 :P Jul 12 18:28:03 Oh dammit. Jul 12 18:28:06 reboots not needed so much Jul 12 18:28:08 There's more, isn't there. Jul 12 18:28:12 yeah Jul 12 18:28:29 Ah well. Jul 12 18:28:32 you gotta edit the mynetworkname to your essid Jul 12 18:28:44 Oh yeah duh Jul 12 18:28:44 and the mysecretpassword part Jul 12 18:28:50 Silly me. Jul 12 18:28:54 plus prayer may help Jul 12 18:29:02 cause the wlan stugg Jul 12 18:29:05 stuff Jul 12 18:29:10 can just work or not Jul 12 18:29:33 if you are using wpa Jul 12 18:29:59 that should work assume wpa-supplicant is in the default image Jul 12 18:30:27 if not then you are going to have to get it but Im guessing its there Jul 12 18:30:56 are you rebooted yet Jul 12 18:31:03 Yup Jul 12 18:31:25 lsmod to test that the /etc/modules permanent worked Jul 12 18:31:43 Yep Jul 12 18:31:46 cool Jul 12 18:32:01 now nano /etc/network/interfaces Jul 12 18:32:02 Now the settings are correct, another reboot? Jul 12 18:32:08 no Jul 12 18:32:16 Really? Jul 12 18:32:16 did you upgrade the kernel Jul 12 18:32:22 Err. Jul 12 18:32:25 no you didn't Jul 12 18:32:32 so you dont have to reboot Jul 12 18:32:34 :) Jul 12 18:32:39 Shit Jul 12 18:32:42 Doesn't work. Jul 12 18:32:49 just type ifup wlan0 Jul 12 18:33:30 No lease, failing Jul 12 18:33:40 After sending discover 3 times. Jul 12 18:33:58 yeah thats where you are going to be learning wpa-supplicant and ifup Jul 12 18:34:04 it'll work Jul 12 18:34:23 you just gotta get the interfaces file right Jul 12 18:34:29 But it doesn't yet Jul 12 18:34:37 How do I "get it right"? Jul 12 18:34:40 yeah the interfaces is wrong Jul 12 18:34:49 Why? Jul 12 18:34:57 I dunno Jul 12 18:35:09 like I said the wlan0 has tons of settings Jul 12 18:35:16 * Willdude123 bangs head against desk. Jul 12 18:35:16 I just did the vanilla Jul 12 18:35:26 Is there not some utility to do it for me? Jul 12 18:35:36 not sure Jul 12 18:35:45 Surely can't it detect these said settings? Jul 12 18:35:45 but s your network wep or wpa Jul 12 18:35:51 wpa Jul 12 18:37:58 yeah the interfaces that is suppose to ship with the bb has some other stuff Jul 12 18:38:09 but I dont have that file Jul 12 18:40:51 soory wild since I dont have hardware in my face Im at a loss, but you are past the driver part Jul 12 18:41:14 and my first modprobe experience took me 2 days Jul 12 18:41:40 so you got to learn driver installs without wasting 2 days of your life Jul 12 18:42:04 I spent 2 days to learn how to type 1 line Jul 12 18:42:14 when I was a n00b Jul 12 18:43:51 trying wireless-tools. Jul 12 18:46:36 <_SY_> Hello Jul 12 18:47:05 anyone know the device tree file magic to make sysclk2 output 24 MHz on the bbb? Any pointers would be helpful. I'm not finding anything... Jul 12 18:47:31 <_SY_> and goodbye...got to go shopping for ice cream.... Jul 12 18:54:09 just got my BBB Jul 12 18:55:31 a moment of silence please... Jul 12 18:55:46 How do I set up wpa with iwconfig? Jul 12 19:02:19 Hi everybody. I'm interest to buy my own BBB, but I have some questions in my mind. Can BBB run any Linux distro which supports ARMv7? This is very unclear to me: why there are many 3rd party Linux ARMhf-images by Robert Nelson? Isn't the normal kernel ok? There are also prebuild Ubuntu/Debian images. Why couldn't we just download the "real" installation image? Jul 12 19:03:04 heh Jul 12 19:03:13 "normal kernel" Jul 12 19:03:26 Willdude123: that was one of those google easies Jul 12 19:03:52 mranostay: gm Jul 12 19:08:14 djlewis: how is the AR? Jul 12 19:08:56 Hey I tried your example "echo yoyoyo 1>&2 | cat 2>&1 | tee yo.txt" again. It executes and displays in commandline, but the yo.txt stays empty?! Jul 12 19:09:52 koen: is GateOne known to work under any particular circumstance? Jul 12 19:11:14 * jkridner sees it working under Firefox, but not Chrome these days. Jul 12 19:11:20 6/20 image Jul 12 19:11:46 Ulaanbaatar, Angstrom supports armv7 Jul 12 19:12:20 Bash_: what are you trying to do? Jul 12 19:12:58 trying to write the output of a java program into a text file Jul 12 19:14:09 What "normal kernel"? Did I misunderstand something wrong? Jul 12 19:14:25 is your filesystem writable Jul 12 19:14:28 $java -jar java-program &> output.txt worked fine. Jul 12 19:15:21 cat yo.txt shows nothing ? Jul 12 19:15:42 yes, it is, if I have some lines allready stored in the yo.txt and run "echo yoyoyo 1>&2 | cat 2>&1 | tee yo.txt" then the text-file is cleared after that execution. Jul 12 19:16:08 I am running that on BBB Arch Linux Jul 12 19:17:28 <_SY_> Bash_: What are you using as an IDE ? Jul 12 19:18:23 how can I figure that out? Jul 12 19:18:24 yeah thats broke I just tested it Jul 12 19:18:38 <_SY_> Are you using the openjdk-6 Jul 12 19:18:48 oracle jdk7 Jul 12 19:18:51 embedded arm Jul 12 19:19:20 <_SY_> For example, I use Eclipse Juno to write the code and remote debug on beagle. Jul 12 19:19:59 I guess I got just an IO command problem, the rest should be fine Jul 12 19:20:18 the 2>&1 | tee file Jul 12 19:20:24 that should work though Jul 12 19:21:09 What is the dhcp client on the bone? Jul 12 19:21:36 $echo yoyoyo 1>&2 | cat 2>&1 | tee yo.txt Jul 12 19:21:57 my test script was bad Jul 12 19:22:08 $echo yoyoyo 2>&1 | tee yo.txt Jul 12 19:22:11 I had the file there already on prevoius test Jul 12 19:22:50 well echo will go to stdout so thats not generating any stderr Jul 12 19:22:58 nice, that works!! Jul 12 19:23:04 gcc Jul 12 19:23:08 oops Jul 12 19:23:50 dhcpcd is not on there, so how do I connect ???? Jul 12 19:25:32 udhcpc Jul 12 19:25:37 Willdude123 ^ Jul 12 19:27:01 And how do I connect? So in dhcpcd I'd do dhcpcd -A wlan0 Jul 12 19:27:18 yeah I just wrote a c program printed to stderr and stdout Jul 12 19:27:27 the 2>&1 worked fine Jul 12 19:27:29 dhcpd is the server component Jul 12 19:27:36 and did it on my brand new BBB Jul 12 19:27:53 comes with gcc out of box :) Jul 12 19:28:07 x56: I'm really confused. Jul 12 19:28:22 x56: I have a wireless connection on wlan0 Jul 12 19:28:25 if you're looking for the client command for configuring a specific interace: "udhcpc -i " Jul 12 19:28:33 my final test was ./a.out 2>&1 | tee yo.txt Jul 12 19:28:44 and both outs went in the file Jul 12 19:29:31 willdude: I just plugged in my wifi dongle to see Jul 12 19:29:36 yeah nice I am running the new benchmark allready and the output is going into my txt-tile and the screen :) Jul 12 19:29:58 cool so first time you must of had a PEBKAC Jul 12 19:30:06 cause I told you same thing Jul 12 19:30:19 WTF???? Jul 12 19:30:27 Sending discover... Jul 12 19:30:39 Over and over and over and over and over and over again Jul 12 19:31:02 oh and willdude the interfaces file was missing cause the out of box uses networkmanager Jul 12 19:31:14 jsarman thanks Jul 12 19:31:19 Oh and I am using wpa_supplement Jul 12 19:31:30 which can be accessed if you have hdmi plug keyboard mouse Jul 12 19:31:32 *supplicant Jul 12 19:31:38 yeah Jul 12 19:31:50 And it should work. Jul 12 19:31:59 it thats used regardless of iterfaces or networkmanager Jul 12 19:32:11 But this fucking udhcpc thing is on an infinite loop of sending discover. ffs Jul 12 19:32:17 ctrl c Jul 12 19:32:32 cause your setup still wrong :) Jul 12 19:32:35 Now I see why linux isn't used for saving any lives. Jul 12 19:32:40 somehow something is wrong Jul 12 19:32:49 hahaha Jul 12 19:32:49 Oh ffs wha the fuck can be wrong? Jul 12 19:33:03 dude if you had the hdmi keyboard mouse it would have been a few clicks Jul 12 19:33:03 [15:31:02] oh and willdude the interfaces file was missing cause the out of box uses networkmanager Jul 12 19:33:11 ;) Jul 12 19:33:35 But I don't. Jul 12 19:33:54 FFS this is impossible. Jul 12 19:33:54 me either like I said just got my BB like 15 minutes ago Jul 12 19:34:07 * mranostay 's noob meter is registering 11 Jul 12 19:34:07 found an old wifi dongle not even sure if it works Jul 12 19:34:19 Im trying now Jul 12 19:34:27 Please tell me your wifi dongle is the same. Jul 12 19:34:30 Please. Jul 12 19:34:40 Well. Actually. Jul 12 19:34:41 it wont matter Jul 12 19:34:46 It doesn't matter. Jul 12 19:34:51 the driver stuff remember Jul 12 19:34:54 mine is above average Jul 12 19:34:56 Let's do it together! Jul 12 19:34:59 look at your lsmod Jul 12 19:35:21 the driver is used by higer level driver to abstract the hardware out Jul 12 19:35:38 Torvolds and crew are geniouses Jul 12 19:35:47 jsarman: Okay... Jul 12 19:37:16 Right Jul 12 19:38:19 URRRGH this whole thing is fucked up and will it even recognize the interfaces file? Jul 12 19:38:33 Because it should be bloody setup for god's sake. Jul 12 19:38:35 * Willdude123 cries Jul 12 19:38:41 n00b Jul 12 19:38:51 Sorry? Jul 12 19:39:22 WTF? Please help rather than calling me a noob.

Jul 12 19:54:06 * ezequielgarcia is trying and lcd4 and shivers with geek excitement Jul 12 19:54:55 I'm trying to get a USB WLAN adapter (AWUS036H, rtl8187 chipset) working with a Beaglebone Black. I've tried loading the module and bringing up the interface to no avail. Strangely, I can only seem to get it working by connecting the device and running "lsusb -v" (just "lsusb" does not suffice) Jul 12 19:55:09 I'm running the latest Angstrom distro Jul 12 19:56:29 Did you load the correct module? Jul 12 19:56:38 yes Jul 12 19:56:40 win18 Jul 12 19:56:43 rtl8187 Jul 12 19:57:29 and ip link set dev wlan0 up works? Jul 12 19:58:38 alright got my serial debug serial working Jul 12 19:58:45 Hi jsarman Jul 12 19:58:55 and now the belkin is showing Jul 12 19:58:59 the device does not exist until I run "lsusb -v" Jul 12 19:59:05 so I gotta go down driver route Jul 12 19:59:06 Can you help me yet? Jul 12 19:59:19 im trying Jul 12 19:59:24 kk Jul 12 19:59:29 thx Jul 12 19:59:50 it's not that the interface is down, "ifconfig -a" does not show wlan0 until after running the "lsusb -v" command Jul 12 19:59:56 x56: lsusb doesn't bring it up Jul 12 20:00:04 weird Jul 12 20:00:08 yeah Jul 12 20:00:14 it has me baffled Jul 12 20:00:17 what happens if you try and bring it up Jul 12 20:00:24 my crap wifi dongle needs some nonfree firmware so Im tracking that down Jul 12 20:00:55 mranostay, from up here in my tree I can spell D S L R Jul 12 20:00:56 :) Jul 12 20:00:57 lsusb should have nothing to do with it Jul 12 20:01:01 that's insane Jul 12 20:01:10 little question here Jul 12 20:01:13 so I'm sure there's something underlying, but I have no idea what it is Jul 12 20:01:22 if i got a raw lcd panel Jul 12 20:01:25 and this http://www.ebay.com/itm/170929941835 Jul 12 20:01:34 and a mini hdmi to vga cable Jul 12 20:01:43 would it "just work" with beaglebone black? Jul 12 20:01:54 or am i over simplyfying it Jul 12 20:01:58 x56 so you can bring it up fine after lsubs? Jul 12 20:01:59 bradfa: have a 'real' camera coming.. you know what those are? Jul 12 20:02:02 lsusb* Jul 12 20:02:06 EasyAt yes Jul 12 20:02:13 haha odd Jul 12 20:02:16 lsusb -v Jul 12 20:02:19 not lsusb Jul 12 20:02:23 haha Jul 12 20:02:30 if it's not verbose, it doesn't do anything Jul 12 20:02:34 mranostay, do you have an old camera yu're not using then? Jul 12 20:02:36 it's a real wtf Jul 12 20:02:41 if so, I can pay for shipping it to me Jul 12 20:03:00 I'm about to start looking at lsusb source if no one has a better idea xD Jul 12 20:03:07 heh nope just my iphone Jul 12 20:03:11 I'm really curious Jul 12 20:03:14 mranostay, you can ship that to me :) Jul 12 20:03:21 ah how about no Jul 12 20:03:35 mranostay, you don' thave one of those atom based phones yet?

Jul 12 20:16:19 NIN did the music for quake, and it's logo was heavily used Jul 12 20:16:20 oh right Jul 12 20:16:34 thurgood_: yeah i knew it was one of those two Jul 12 20:16:38 * mranostay wasn't a gamer Jul 12 20:16:55 ouch 75$ GA tickets Jul 12 20:18:13 ok got my wlan0 to show with ifconfig Jul 12 20:18:31 had to track down rt73.bin and drop it in /lib/firmware Jul 12 20:18:45 getting closer Jul 12 20:19:07 man willdude you would of had a real bad day if you would have had to figure that out Jul 12 20:19:08 Nice Jul 12 20:19:16 Heh Jul 12 20:19:35 * mranostay blares some NIN at bradfa Jul 12 20:19:38 oh and to get files transfered just plug in the BBB to the PC and drop file into tit Jul 12 20:19:41 * bradfa rocks out Jul 12 20:20:14 then it is at /media/BEAGLEBONE Jul 12 20:21:57 Ah Ok Jul 12 20:22:00 Yey! mainline linux! Jul 12 20:22:11 * bradfa dances Jul 12 20:22:28 So basically you will eventually have the same problem as me. Jul 12 20:22:31 ? Jul 12 20:22:47 bradfa: #beagle mosh pit? Jul 12 20:22:52 mranostay, YES! Jul 12 20:23:07 * bradfa punches randomness! Jul 12 20:23:22 oooo 24 MHz clocks! Jul 12 20:23:22 * mranostay punches fuzzyness! Jul 12 20:26:38 hmm, somehow I seem to have lost mac addresses... Jul 12 20:26:42 * bradfa searches for them... Jul 12 20:31:22 bradfa: i wonder what the NSA thinks of my music listening habits Jul 12 20:31:49 jsarman: How's itmgoing? Jul 12 20:31:53 mranostay, they like it Jul 12 20:32:31 bradfa: "who listens to Bob Dylan and Lamb of God... really?" :) Jul 12 20:32:41 mranostay, they like variety Jul 12 20:39:15 ah, found my mac addresses, apparently that patch is not yet mainlined... Jul 12 20:40:28 can anybody give me any hint for a simple way of testing an lcd on a bbb? Jul 12 20:40:50 fb-test? Jul 12 20:41:10 Can anyone give me a sample network interface file from the BBB? Mine doesn't have one. Jul 12 20:41:54 anyone have trouble compiling rob nelson's debian kernels? Jul 12 20:43:58 Why on windows can I just plug it in and it works, whereas with this I have to do at least 3 hours of frustrating work? Jul 12 20:44:21 Willdude123: because you're lacked of experience Jul 12 20:45:33 So at least one of you must have some experience? Jul 12 20:45:57 I've set up the wpa_supplicant connection, and the dhcp client won't connect. Jul 12 20:46:40 sure there's plenty of experienced guys, they're just busy living their own lives Jul 12 20:46:53 Ack] Jul 12 20:46:57 So annoyed. Jul 12 20:48:09 don't. just work harder and do your own work, *by yourself*. Jul 12 20:48:53 How the fuck am I going to do that? Jul 12 20:48:59 It won't fucking work when I try Jul 12 20:49:07 Then what the fuck do I do? Jul 12 20:49:19 maybe you could start by learning linux.. Jul 12 20:49:25 And how the fuck do you expect me to solve this fucking problem? Jul 12 20:49:32 ffs Jul 12 20:49:55 he... wanna know my problems? wanna solve this instead? Jul 12 20:50:05 i bet mine are tougher... Jul 12 20:50:37 fuck off Jul 12 20:50:44 right... Jul 12 20:51:02 * Willdude123 wants to die now Jul 12 20:51:15 Willdude123: do us a favor ;) Jul 12 20:51:18 Willdude123: ... are you trying to connect to a secured network? Jul 12 20:51:19 against all my instinct... what's your problem? Jul 12 20:51:20 feck off Jul 12 20:51:26 thurgood_: Yest Jul 12 20:51:29 &yes Jul 12 20:51:39 trying to connect to a secured network Jul 12 20:51:47 oi, you aren't going to get any help with that attitude/language Jul 12 20:51:53 Sorry Jul 12 20:51:59 are you using a windows manager? Jul 12 20:52:02 this isn't #rpi, so its ok to cuss now and then, but calm down a bit Jul 12 20:52:04 No ssh Jul 12 20:52:33 ah... hard to set up ssh if you don't have a network connect Jul 12 20:52:43 My problem is http://pastie.org/8135643 Jul 12 20:52:50 I'm using ssh over usb Jul 12 20:53:32 Are you using wpa_supplicant? Jul 12 20:53:39 I set up wlan0 with wpa_supplicant Jul 12 20:53:42 Yep Jul 12 20:53:48 is wlan0 up? and connected? if not dhcp is going to have a hard time Jul 12 20:54:06 How do I check? Doing lsmod lists it. Jul 12 20:54:44 what's the output of ifconfig? Jul 12 20:54:44 Make sure wpa_supplicant negotiated correctly Jul 12 20:54:46 Actually ignore the latter part. Jul 12 20:55:16 http://pastie.org/813565 Jul 12 20:55:23 ifconfig should show it if it's up Jul 12 20:55:51 Above is the output. Jul 12 20:56:03 Russ: yeah some of us are too young to see those naughty words :) Jul 12 20:56:18 I'm 12 Jul 12 20:56:22 *13 Jul 12 20:56:43 that paste shows up as blank Jul 12 20:56:45 the last pastie is empty Jul 12 20:56:50 Oh Jul 12 20:56:59 maybe missing a digit? Jul 12 20:57:01 This? http://pastie.org/8135651 Jul 12 20:57:05 Ah yeah Jul 12 20:57:13 that explains a lot Jul 12 20:57:20 I take it from this that it's not up. Jul 12 20:57:31 Yet I have set it up. Jul 12 20:58:07 it's up but not necessarily connected Jul 12 20:58:21 Oh I connected it. Jul 12 20:58:25 did you run wpa_supplicant manually? Jul 12 20:58:38 Willdude123: Yeah, run wpa_supplicant manually and see what it says Jul 12 20:59:04 once you have it working on the command line you can move it into the interfaces file Jul 12 20:59:45 http://pastie.org/8135668 Jul 12 20:59:53 Run it manually? Jul 12 21:00:17 That's what I did Jul 12 21:00:40 -B runs it in the background Jul 12 21:00:45 don't do that Jul 12 21:02:10 http://pastie.org/8135674 Jul 12 21:02:49 you can add the -B when you move it to your interfaces file Jul 12 21:03:06 take out the space after -c as well Jul 12 21:03:09 Move what? Jul 12 21:04:23 When I take the B out, that's what I got ^ Jul 12 21:06:43 So what's the problem? Jul 12 21:07:18 yeah... you might want to double check the passphrase for starters Jul 12 21:08:16 It's correct. Jul 12 21:09:58 One sec. Jul 12 21:10:16 Ah the LED on the wifi dongle wasn't blinking- I'm rebooting. Jul 12 21:11:21 Ooh Jul 12 21:11:28 A different error message. Jul 12 21:12:33 http://pastie.org/8135698 Jul 12 21:13:47 you had that error before as well Jul 12 21:14:19 Reallu? Jul 12 21:14:22 *really Jul 12 21:14:30 Don't recognize it. Jul 12 21:14:32 Anyway. Jul 12 21:14:37 Why is it doing it? Jul 12 21:14:51 not sure Jul 12 21:15:00 is the driver loaded? Jul 12 21:15:11 Yes Jul 12 21:15:34 so it shows up properly in lsmod> Jul 12 21:15:36 > Jul 12 21:15:37 ? Jul 12 21:15:45 Yup Jul 12 21:18:05 what adapter are you using? Jul 12 21:18:35 rtl8187l based netgear thing Jul 12 21:24:23 Willdude123: If you want a pretty good general guide for setting up wifi in Linux, read this: https://wiki.archlinux.org/index.php/Wireless_Setup Jul 12 21:24:44 georgem: Okay. Jul 12 21:24:47 I'm fighting with a rtl8187 device myself Jul 12 21:24:49 But it should be working. Jul 12 21:25:12 https://wiki.archlinux.org/index.php/Rtl8187_wireless Jul 12 21:25:16 sounds likely to be a different issue, as you're stuck at a different point Jul 12 21:25:39 I'll report back if I find anything relevant though Jul 12 21:25:48 Does it matter that there's no network interfaces file? Jul 12 21:26:01 Willdude123: Not for setting it up manually Jul 12 21:26:44 As opposed to setting it up with the gui? Jul 12 21:26:50 Can you get it to list wifi networks? Like with "iw dev wlan0 scan" or "iwlist wlan0 scan" Jul 12 21:27:04 If you can't its screwed for some reason Jul 12 21:28:05 if that works at least you know the driver and hardware appear to be working Jul 12 21:28:22 root@beaglebone:~# iwlist wlan0 scan Jul 12 21:28:22 wlan0 Interface doesn't support scanning : Network is down Jul 12 21:28:34 Argh ffs Jul 12 21:28:38 try: iwconfig wlan0 up Jul 12 21:28:54 iwconfig: unknown command "up" Jul 12 21:29:08 So this means the driver isn't working. Jul 12 21:29:10 ugh. my memory is faulty. let me check the man page Jul 12 21:29:14 or `ifup wlan0` Jul 12 21:29:16 But it bloody well should do. Jul 12 21:29:23 once I get my interface up, scanning works fine, and I'm using the same chipset Jul 12 21:29:31 the driver is probably not the issue Jul 12 21:29:44 rtl8187 that is Jul 12 21:29:50 http://pastie.org/8135741 Jul 12 21:30:16 but can you scan now? Jul 12 21:30:28 ok. try: ifconfig wlan0 up. then iwlist wlan0 scan Jul 12 21:30:42 Yeah Jul 12 21:30:46 I can now. Jul 12 21:30:53 ok. now run wpa_supplicant Jul 12 21:31:16 root@beaglebone:~# wpa_supplicant -i wlan0 -D nl80211 -c L Jul 12 21:31:18 Right? Jul 12 21:31:33 Same error Jul 12 21:31:43 L is your configuration file? Jul 12 21:32:07 Yeah it's the one i did wpa_passphrase to Jul 12 21:32:40 paste the contents of it so we can see if it looks correct Jul 12 21:33:18 Or double check it yourself against the information here: http://linux.die.net/man/5/wpa_supplicant.conf Jul 12 21:34:33 that man page actually sucks pretty bad Jul 12 21:34:50 http://paste.ubuntu.com/5869362/ Jul 12 21:39:05 it still says "WPA: 4-Way Handshake failed - pre-shared key may be incorrect"? Jul 12 21:40:02 Yeah Jul 12 21:40:22 try putting the passphrase directly into your config file with quotes Jul 12 21:40:58 yeah. thats what I was going to suggest Jul 12 21:41:04 psk="very secret passphrase" Jul 12 21:41:08 root@beaglebone:~# wpa_supplicant -B -i wlan0 -D nl80211 -c network={ ssid="linksys" #psk="wbridge45" psk=f808897b689662637686462d3fd204b0890e16575441f876256c9bbf42a7a57d } Jul 12 21:41:11 Failed to read or parse configuration '/home/root/network={'. Jul 12 21:41:52 put it in a file. then do: wpa_supplicant -B -i wlan0 -D nl80211 -c file Jul 12 21:42:09 Tha't what I did though. Jul 12 21:42:26 You tried psk both ways? Jul 12 21:43:20 Both ways? Jul 12 21:43:29 psk="" Jul 12 21:43:36 yeah Jul 12 21:43:37 I'll try that. Jul 12 21:43:39 vs psx=123 Jul 12 21:43:42 right Jul 12 21:43:44 err psk Jul 12 21:43:56 Can't pass directly to it evidently. Jul 12 21:44:08 Have to use a file. Jul 12 21:44:11 yeah Jul 12 21:44:33 So with no passphrase Jul 12 21:44:54 so #psk="whatever" and psk= ? Jul 12 21:44:59 no with psk="wbridge45" Jul 12 21:45:02 or whatever Jul 12 21:45:06 Oh shoot Jul 12 21:45:08 heh Jul 12 21:45:12 Right Jul 12 21:45:22 without the # on the first one Jul 12 21:45:27 If I come all the way to your house I think you've got bigger problems :P Jul 12 21:45:39 lol Jul 12 21:45:55 Should I include the second psk= too? Jul 12 21:45:58 no Jul 12 21:45:58 no Jul 12 21:46:10 just put a # in front of it Jul 12 21:46:42 Too late, deleted. Jul 12 21:46:48 ok Jul 12 21:46:58 Same error Jul 12 21:48:19 Exactly Jul 12 21:49:23 and your ssid is still linksys? Jul 12 21:49:38 Yeah Jul 12 21:49:57 you've connected something else to this network recently right? Jul 12 21:50:28 ... with dhcp Jul 12 21:50:30 oh crap... Jul 12 21:50:32 haha Jul 12 21:50:43 I bet someone else has a linksys network and you're connecting theirs Jul 12 21:50:48 No. Jul 12 21:50:54 possibly Jul 12 21:50:56 good morning beaglers Jul 12 21:50:58 Nobody else has one/ Jul 12 21:51:08 howdy cwicks! Jul 12 21:51:13 Well not here,# Jul 12 21:51:13 hrm. ok. if you say so Jul 12 21:51:18 I Jul 12 21:51:22 am not# Jul 12 21:52:05 well... I gotta drive home now before traffic gets bad. If you're still here I should be on in 30 min Jul 12 21:52:13 hi jkridner, i'm training some interns on how to use the irc for support! Jul 12 21:52:48 Oh shit Jul 12 21:53:05 Willdude123: What? Jul 12 21:53:22 You're leaving and I have no hope of getting this working. Jul 12 21:54:11 you're sure that dhcp is enabled on the router currently? Jul 12 21:54:43 Slightly Jul 12 21:54:55 its giving him errors about like ""WPA: 4-Way Handshake failed - pre-shared key may be incorrect"?" Jul 12 21:55:20 yeah I saw that too Jul 12 21:55:44 cwicks: great. consider it 'interaction'. 'support' is such a dirty word. Jul 12 21:56:12 * mranostay harlem shakes in Jul 12 21:56:14 hi jk Jul 12 21:56:18 jkridner: even Jul 12 21:56:39 thurgood_: Yes, I am Jul 12 21:57:23 Willdude123: Google for the error messages WPA Supplicant gives you to find solutions. Jul 12 21:58:58 Willdude123: Maybe you need to specify more details like WPA mode, encryption type etc Jul 12 21:59:07 Not looking promising Jul 12 21:59:18 But how, I don't even know them? Jul 12 21:59:47 howdy mranostay Jul 12 22:00:11 And how the hell am I supposed to pass them as args? Jul 12 22:01:05 jkridner: how is it in node world lately? :) Jul 12 22:01:58 jkridner sorry my browser crashed - ype got that as part of the training - sorry for the vocab Jul 12 22:02:34 are you using wpa or wpa2 on your network? Jul 12 22:03:19 wpa, I think. Jul 12 22:04:28 perhaps add -dd to the command line to get more debug info? Jul 12 22:04:39 Shit it's WPA2 Jul 12 22:04:41 I feel stupid Jul 12 22:04:47 So so so stupid Jul 12 22:05:17 Do I still use the same utility? Jul 12 22:05:25 I think you have to specify the key-mgmt type then Jul 12 22:05:33 How? Jul 12 22:05:53 Is that something I need to do when writing the conf file? Jul 12 22:06:54 Right. Jul 12 22:06:59 I see where it should go/ Jul 12 22:07:17 But should it be key_mgmt=WPA2 then? Jul 12 22:08:08 I think key_mgmt=WPA2-PSK Jul 12 22:08:36 yes, it goes in the configuration file Jul 12 22:09:46 or perhaps key_mgmt=WPA-PSK Jul 12 22:09:51 and proto=WP2 Jul 12 22:10:16 The former is invalid. Jul 12 22:11:07 And so is the latter. Jul 12 22:12:22 what does it show with -dd added to the command ? if you take that stuff out then>? Jul 12 22:13:20 Even when running normally now: rfkill: WLAN hard blocked Jul 12 22:13:21 Could not set interface wlan0 flags: Operation not possible due to RF-kill Jul 12 22:14:25 And led on it is not lighting. Jul 12 22:15:58 Reboot I guess. Jul 12 22:18:27 what does `rfkill list` display? Jul 12 22:19:43 Right, rebooted, all fine. Jul 12 22:19:58 Just pasting the output of -dd Jul 12 22:20:38 http://paste.ubuntu.com/5869452/ Jul 12 22:24:42 thurgood_: There's a lot there that I don't understand. Jul 12 22:25:06 hmmm, what distro are you using? Jul 12 22:25:32 default Jul 12 22:28:55 Right. Jul 12 22:29:05 Well I need some way to use WPA2/ Jul 12 22:30:34 But none are available evidently. Jul 12 22:34:41 Right. Jul 12 22:35:06 Used this code http://wiki.gentoo.org/wiki/Wpa_supplicant#WPA2_with_wpa_supplicant modified a bit. Jul 12 22:35:24 EXACTLY THE SAME PROBLEM!!!! Jul 12 22:35:38 Wait Jul 12 22:35:43 Sorry for caps Jul 12 22:36:15 Half the error has gone :) http://paste.ubuntu.com/5869484/ Jul 12 22:36:20 It's only that now! Jul 12 22:36:52 have you tried -Dwext Jul 12 22:37:10 anybody here with experience with usb g_serial ? i'm trying to talk to g_serial on BBB from an Android device with host capabilities. Jul 12 22:37:37 No what does it do? Jul 12 22:38:26 uses the default wireless extensions if your driver supports it Jul 12 22:39:23 http://paste.ubuntu.com/5869496/ Jul 12 22:39:30 That's the error when I use that Jul 12 22:40:17 The irony of the term "busy" it's been sat here since 7 pm doing buggar all. Jul 12 22:40:31 okay are the lights off again? Jul 12 22:40:51 After running the command yes, but during it they are on. Jul 12 22:45:34 WTF? Jul 12 22:46:05 Why would it be busy? Jul 12 22:46:20 Is anyone actually around? Jul 12 22:47:23 is it still busy from the previous wpa_supplicant call? Jul 12 22:48:14 Doubt it, I control c-ed it. Jul 12 22:48:19 And rebooted it. Jul 12 22:48:41 So yeah, shouldn't be busy, and isn't/ Jul 12 22:51:09 I'm never gonna get this sorted am I/ Jul 12 22:59:18 Anyway I have to sleep now. Jul 12 22:59:55 This fucking thing will never work, so anybody got suggestions for a better wifi dongle? Jul 12 23:01:22 swearing will not help Jul 12 23:01:40 it might a little Jul 12 23:01:56 the dongle might feel shame Jul 12 23:07:37 Threaten it with a big hammer. Jul 12 23:08:12 SpeedEvil, I recogmize you from somewhere. Jul 12 23:08:27 You a HABer or a wikipedian? Jul 12 23:08:28 Willdude123: openmoko? Maemo? electronics? physics? Jul 12 23:08:32 hab Jul 12 23:08:38 * SpeedEvil is not awake at the moment. Jul 12 23:08:40 Ah right. Jul 12 23:08:49 #highaltitude :-) Jul 12 23:08:52 gah adb has no shell control Jul 12 23:09:19 Russ, you a habber? I recognize your nick. Jul 12 23:09:30 what's a habber? Jul 12 23:09:37 Obvs not Jul 12 23:09:45 High altitude ballooning. Jul 12 23:09:55 Someone that launches high altitude balloons, or is interested in the same. Jul 12 23:10:12 doing a google search for habber is decidedly unhelpful, and somewhat scary Jul 12 23:10:31 Russ: ud first link? Jul 12 23:10:50 what's wrong with people? Jul 12 23:11:18 not only that, but habberdasher is already a word Jul 12 23:11:40 er, haberdasher Jul 12 23:11:58 what is a extra b among friends? Jul 12 23:12:17 depends on if it's /b/, I'm pretty sure that's who writes most of the ud entries Jul 12 23:12:34 So is there any point comtinuing with my attempts at the wifi dongle? Jul 12 23:12:44 Russ: *touche* Jul 12 23:12:44 I feel suicidal now, afk. Jul 12 23:12:54 oh boys Jul 12 23:16:22 Russ: should we tell him tech gets worse when you have to do it for a day job :) Jul 12 23:20:22 wifi is an unpredictable medium, errors are normal Jul 12 23:20:29 I'm having issues getting 3.3v from VDD_3V3EXP Jul 12 23:21:02 Anyone has any clue what may be happening? It reads 1.21v instead of 3.3v Jul 12 23:33:32 mranostay, what are you working on these days? Jul 12 23:46:23 hello Jul 12 23:47:05 I'm looking for help with the 3.3v port in my BB white. For some reason I'm reading 1.4v instead of 3,3v Jul 12 23:47:19 The revision is A3 Jul 12 23:52:08 which pin? Jul 12 23:54:58 Pint: P9 - 3, VDD_3V3EXP Jul 12 23:58:03 xj6: what are you readin it with? Jul 12 23:58:13 Voltimeter Jul 12 23:58:22 DC Jul 12 23:58:22 yeah how cheap? :) Jul 12 23:58:39 Very...., but th 5v reading is ok, 4.98v Jul 12 23:58:57 i doubt the 1.4v number Jul 12 23:59:06 is it running? :) Jul 13 00:00:00 xj6: heh you aren't measuring the 5v pin to 3.3v pin right? :) Jul 13 00:00:03 Yeah. I have a nodejs app running. It works. I can do the blinking led and all. But VDD_3V3EXP is reading 1.4v Jul 13 00:00:28 1.4v to ground, correct? :) Jul 13 00:00:32 Nope, measuring from GND, pin P9-1 Jul 13 00:00:58 ok good because 5v - 3.3v is aweful close :) Jul 13 00:01:29 Yeah, just realized the same and went to check my design... no luck though :( Jul 13 00:03:45 Let me check a different multimeter Jul 13 00:05:14 i'm going to guess a crappy multimeter Jul 13 00:05:22 but DC voltage shouldn't matter too much Jul 13 00:05:52 The other multimeter measures 1.35v... there's something wrong here. I'll measure a IO pin at HIGH to see if its 3.3 or less Jul 13 00:08:47 Output on the pin is 3.3v...GRRRR, what's going on? It doesn't make sense Jul 13 00:17:29 hi everybody Jul 13 00:18:43 I got some problem with a beaglebone Jul 13 00:19:49 I am working on linux and i saw that when it is connect via usb there should be /dev/ttyUSB0 and /dev/ttyUSB1 Jul 13 00:20:00 but i only get the first one Jul 13 00:26:45 need some help to find a modem board... Jul 13 00:29:57 and me to just communicate with the beaglebone Jul 13 00:31:24 hey busrsy, what do you intend to do? Jul 13 00:31:29 beaglebone or Pi Jul 13 00:33:37 bursy why should there be a /dev/ttyUSB1 Jul 13 00:34:08 jsarman: i saw this on a website Jul 13 00:34:26 ok it was wrong or you read it wrong Jul 13 00:34:54 i can give you the link if you want to ceck Jul 13 00:34:55 ttyUSB* is a usb to serial dev Jul 13 00:35:08 so 1 per usb to serial Jul 13 00:35:27 if you had two usb to serials then yeah Jul 13 00:35:43 first time yes now no Jul 13 00:36:19 you gotta lsusb and show the two unique devs Jul 13 00:39:05 sorry english is not my native language. when i do lsusb what might i get? Jul 13 00:39:41 the usb listing Jul 13 00:44:22 ls = list Jul 13 00:44:23 ok i can also see it with ls in /dev no? Jul 13 00:44:23 lsusb list the usb devices Jul 13 00:44:23 ok it's done Jul 13 00:44:23 lspci the pci Jul 13 00:44:23 lsmod the modules Jul 13 00:44:23 so did you see two usb to serial devices Jul 13 00:44:23 this guy has a modem board for beagle/Pi http://elhep.ise.pw.edu.pl/node/124 Jul 13 00:44:24 I see 8 lines numbered from device 001 to 008 so i guess 8 device Jul 13 00:44:29 Bus 001 Device 002: ID 050d:705a Belkin Components F5D7050 Wireless G Adapter v3000 [Ralink RT2571W] Jul 13 00:44:32 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Jul 13 00:44:35 Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Jul 13 00:44:37 is my BBB Jul 13 00:44:56 I have 0 usb to serials Jul 13 00:44:58 yes things likes this Jul 13 00:45:39 so dont look at the bus stuff or the root huba Jul 13 00:45:40 hubs Jul 13 00:46:10 just search the names of the devices like in my case I would search F5D7050 Jul 13 00:47:02 it says wireless G adapter so I know it is not a Usb to serial Jul 13 00:47:18 i have one USB-UART is it this ones Jul 13 00:47:33 thats ttyUSB0 Jul 13 00:48:13 you could grep your log files for ttyUSB0 and get more info Jul 13 00:48:32 maybe dmesg | grep ttyUSB Jul 13 00:49:35 that say FTDI usb serial converter now attached to USB0 Jul 13 00:49:49 ttyUSB0* Jul 13 00:50:15 yep Jul 13 00:50:24 thats why you have 1 Jul 13 00:50:34 ok Jul 13 00:53:22 so how am i suppose to access to the beaglebone ? i tried with screen /dev/ttyUSB0 115200 but it doesnt work Jul 13 00:55:36 well screen wont do it Jul 13 00:55:41 try minicom Jul 13 00:56:33 same line just replacing screen by minicom? Jul 13 00:58:56 http://www.lvr.com/beaglebone.htm it was on this website that said screen and two serial ports Jul 13 00:59:08 minicom is a serial terminal for linux Jul 13 00:59:38 it lets you send output and read input from a serial port Jul 13 00:59:53 plus tons of ole school serial functionsl Jul 13 01:00:11 ok i have to install it Jul 13 01:00:18 but you just need to open it configure it Jul 13 01:00:20 it's not on my linux Jul 13 01:00:30 yeah apt-get install minicom Jul 13 01:00:39 if ubuntu Jul 13 01:01:07 debian but the same Jul 13 01:02:29 how can i change the port?

Jul 13 01:08:20 after that goto modem and dial up Jul 13 01:08:24 erase all that Jul 13 01:08:41 jmoyerman: yep Jul 13 01:08:55 mainly A the init string Jul 13 01:09:28 have you noticed any pinout issues on the JA-JC header? Jul 13 01:09:35 when finish goto Save setup as dfl Jul 13 01:09:44 the exit Jul 13 01:09:56 heres the dumb part Jul 13 01:09:58 I'm pulling my hair out right now, triple checked the UCF and schematic (copied your .ucf file) Jul 13 01:10:06 i erase everything in modem? Jul 13 01:10:24 otherwise it prints to the serial when you open Jul 13 01:10:41 you dont have to but it makes it cleaner Jul 13 01:11:09 minicom is ole school serial modem frontend Jul 13 01:11:35 so it can send all the ATDT blah blah commands Jul 13 01:11:46 to make an actual modem command Jul 13 01:11:53 but you dont need all that Jul 13 01:12:04 ok Jul 13 01:12:14 anyways the dumb part is after you save to dfl Jul 13 01:12:17 then exit Jul 13 01:12:26 you have to ctrl A then Q Jul 13 01:12:33 which closes program Jul 13 01:12:37 then restart it Jul 13 01:13:17 ok give the time to erase everything Jul 13 01:13:25 yeah Jul 13 01:13:35 that part sucks Jul 13 01:18:08 ok i restarted it Jul 13 01:19:01 if you are connected to the debug serial port then if you hit enter you should see something Jul 13 01:19:05 sorry to bug in the conversation you have a modem attached to the BBB ? Jul 13 01:19:08 emeb: never mind Jul 13 01:19:15 if you are connected via the usb then the baud rate need to be 9600 Jul 13 01:19:17 nah Jul 13 01:19:32 hes just using mincom with null modem serial cable Jul 13 01:19:49 jmoyerman: tease. :) Jul 13 01:19:51 to speak from BB where? Jul 13 01:20:01 right beside him Jul 13 01:20:15 hes just doing the serial conn locally Jul 13 01:20:21 ahh Jul 13 01:20:26 thought he had g_serial active Jul 13 01:20:39 and tried to speak through that Jul 13 01:20:45 emeb: I apparantly just can't read. Jul 13 01:20:48 but this thing would do modem all day the pins are available for controlling full modeme Jul 13 01:21:50 yes it works Jul 13 01:22:00 you welcome Jul 13 01:22:06 i justed log into angstrom Jul 13 01:22:12 Give me a thank you in your native language Jul 13 01:22:17 thank you so much Jul 13 01:22:20 merci beacoup Jul 13 01:22:26 beaucoup Jul 13 01:22:39 je parle pais francais comme se comme sa Jul 13 01:22:59 just kidding I took french in high school thats all i remember Jul 13 01:23:43 almost good Jul 13 01:23:44 are you from USA? Jul 13 01:23:44 i learned je naige (Im swimming) slang for I dont know Jul 13 01:23:44 yeah Jul 13 01:24:15 ok I am in California right now Jul 13 01:24:17 my teacher taught the the I dont know so I used that for the rest of class :) Jul 13 01:24:26 Florida Jul 13 01:24:58 alright bursy get to hacking Jul 13 01:25:24 thank you again Jul 13 01:26:03 so now i guess i can copy a file from my computer to the BB Jul 13 01:26:36 well yeah but the easy way to do that is to just plug into the usb Jul 13 01:26:55 then it comes up as a SD card like device Jul 13 01:27:04 drop your file into the folder Jul 13 01:27:18 then you can find it at /media/BEAGLEBOARD Jul 13 01:27:37 i am dumb i didn't thought that Jul 13 01:27:38 at least thats true on the beagleboneblack bbb Jul 13 01:28:00 it's much easier i guess Jul 13 01:28:04 if you wanna do it over minicom then you gotta learn xmodem Jul 13 01:28:24 which I'm not going over that tonight Jul 13 01:28:30 what is that? Jul 13 01:28:38 thats your lesson Jul 13 01:28:56 i mean xmodem Jul 13 01:28:57 wanna work to bad ass then learn xmodem without help Jul 13 01:29:15 xmodem is ole school way to move a file over a serial port Jul 13 01:29:37 very effective, but nowadays not needed Jul 13 01:30:17 ok Jul 13 01:30:22 now we have ssh the usb gadget, and many more high bandwidth solutions Jul 13 01:30:24 thank you again Jul 13 01:31:12 De rien Jul 13 01:31:15 i have to go now Jul 13 01:32:16 jsarman: any experience with usb g_serial? Jul 13 01:33:13 nah Ill google it though Jul 13 01:34:20 i know now :) Jul 13 01:34:47 thats how they make the BBB's client usb look like a serial device to the host OS Jul 13 01:34:56 ok now for the 2nd question any knowledge about android host java api? Jul 13 01:35:08 im a Java guru Jul 13 01:35:16 i have an awkward problem Jul 13 01:35:25 i compiled the BBB kernel with g_serial in it Jul 13 01:35:30 but android not yet cause nobody has contracted me Jul 13 01:35:42 so no modprobe, just from the start g_serial on usb port Jul 13 01:36:01 if i do cat ttyGS0 on BBB and echo on the ttyACM0 on android it works like a charm Jul 13 01:36:17 this is from console *root required* Jul 13 01:36:18 well if you set it to Y and not M you dont need to modprobe it Jul 13 01:36:26 yep Jul 13 01:36:31 i did like that Jul 13 01:36:50 you compiled into the kernel Jul 13 01:36:54 yep Jul 13 01:37:12 so whats the issue Jul 13 01:37:30 console to console *cat on BBB echo on Android* communication works Jul 13 01:37:52 but if i cat on the tty port on BBB and try to send data from Java usb host api i don`t receive stuff Jul 13 01:38:07 well you may need to use setserial Jul 13 01:38:18 google that Jul 13 01:38:42 mhmh but if i send from BBB and try to read form java i can do it with no rpoblem Jul 13 01:38:43 problem Jul 13 01:39:04 in java when i do serial i use rxtx Jul 13 01:39:21 im not sure with andriod Jul 13 01:39:40 android is a bit tricky, i am using the host api to avoid rooting the device Jul 13 01:39:52 what I would be checking for Jul 13 01:39:58 is baud correct Jul 13 01:40:07 is flow control disables Jul 13 01:40:28 yeah but wouldn`t this affect reading data also? Jul 13 01:40:46 not always flow control can make things weird Jul 13 01:40:53 if you arent sure Jul 13 01:41:01 so just disable it Jul 13 01:41:27 need to figure out how from inside android Jul 13 01:41:45 my guess is that its sticking in a buffer waiting for proper RTC /CTS signals Jul 13 01:41:51 RTS Jul 13 01:42:38 mhmh need to see Jul 13 01:43:08 So the language is usually like 8_N_1 none Jul 13 01:43:30 jsarman: http://beagleboard.org/project/BBBabb/ Jul 13 01:43:32 this is the project Jul 13 01:43:34 which means 8 bit no parity 1 stop and no flow contol Jul 13 01:43:53 it is for Google Summer of Code Jul 13 01:46:21 send me the link to the android javadocs for the serial stuff Jul 13 01:46:37 jsarman: this is the catch there is no serial stuff Jul 13 01:46:47 just communication with usb device Jul 13 01:47:04 i see the BBB as a usb device Jul 13 01:47:05 hmm g_serial makes it into a serial port for host Jul 13 01:47:13 the host would need a driver Jul 13 01:47:24 yes but i disconnect the driver from the kernel and take over the device Jul 13 01:47:31 and need to write my own *driver* Jul 13 01:47:49 * vvu|Mobile did this for RNDIS to usb boot the AM335x chip Jul 13 01:47:58 wow Im cool with that but I cant help without some source in this case Jul 13 01:48:30 jsarman: http://developer.android.com/guide/topics/connectivity/usb/host.html Jul 13 01:48:35 you actually have a non noob problem Jul 13 01:48:37 this is the thingie i need to use Jul 13 01:49:02 mainly http://developer.android.com/reference/android/hardware/usb/UsbDeviceConnection.html#bulkTransfer(android.hardware.usb.UsbEndpoint, byte[], int, int) Jul 13 01:49:28 so you are writing the host driver to interface with g_serial Jul 13 01:49:34 for andriod Jul 13 01:49:46 yep Jul 13 01:50:18 to see the bigger picture at this point i can boot the BBB from an android device. boot as in having a small ramdisk with busybox in it Jul 13 01:50:23 furthurmore you have been able to send data to the android device from the BBB Jul 13 01:50:35 now i want to flash the eMMC with data received from android Jul 13 01:50:42 yes, with the host API Jul 13 01:50:46 I read the link you sent me Jul 13 01:51:01 but i can`t send the other way around android->BBB *java* Jul 13 01:51:13 but now I just doing what my professor taught me. Jul 13 01:51:20 1. Solve hardest problem Jul 13 01:51:20 to be noted that from terminal on both ends works with no problem Jul 13 01:51:35 2 repeat step 1 until all problems are solved Jul 13 01:51:37 this is the curious thing :) Jul 13 01:52:19 how did you send the data Jul 13 01:52:31 terminal or java? Jul 13 01:52:37 did you echo noise > /dev/theserialdev Jul 13 01:52:41 yep Jul 13 01:53:09 then do something like less /dev/theserialdev Jul 13 01:53:12 and get nothing Jul 13 01:54:02 can`t test right now, have all things packed at another location :( Jul 13 01:54:15 cause if so you have to do the setserial Jul 13 01:54:31 I think you need to mess with seterial Jul 13 01:54:42 its cryptic Jul 13 01:54:48 setserial on the BBB or android? Jul 13 01:54:54 on the BBB Jul 13 01:54:55 if it is on BBB it`s ok Jul 13 01:55:04 but heres the hack Jul 13 01:55:09 set up minicom Jul 13 01:55:12 on android i need to avoid all terminal/rooting stuff Jul 13 01:55:30 then if you saw me telling the french dude ow to set it up then do that Jul 13 01:55:49 minicom just uses setserial Jul 13 01:55:51 did not follow the discussion Jul 13 01:56:00 just at the end popped up Jul 13 01:56:03 ok minicom is a modem app Jul 13 01:56:27 it also configs the serial port using setserial internally Jul 13 01:56:40 yep used it a couple of times but not extensively Jul 13 01:56:51 so if you brought up minicom configured it for the serial port Jul 13 01:57:07 one of the options is Hardware flowcontrol Jul 13 01:57:16 once you disable it Jul 13 01:57:30 then you may see the data from the Andriod Jul 13 01:57:42 if so then you know its a flow control issue Jul 13 01:58:11 mhmh Jul 13 01:58:17 thats the easy way test Jul 13 01:58:34 the harder way is to learn how to communicate with setserial Jul 13 01:58:54 yup but what is the trick that terminal to terminal *cat echo* style works both ways *reading/writing from Android to BBB*? Jul 13 01:59:51 Im shooting from the hip here Jul 13 02:00:10 true Jul 13 02:00:17 but have went down the s__t flow control was the problem road Jul 13 02:00:30 mhmh at least i have an idea what to debug Jul 13 02:00:40 yeah thats all Im doing Jul 13 02:00:52 giving you debug ideas Jul 13 02:01:02 you better be opensourcing your code Jul 13 02:01:09 yep Jul 13 02:01:10 it is Jul 13 02:01:13 ok Jul 13 02:01:28 http://beagleboot.vdev.ro/ Jul 13 02:01:42 make a small guide how to boot that thingie up Jul 13 02:02:02 hey gang Jul 13 02:02:03 maybe someone will use the project even if it has sooo many hacks in it :) Jul 13 02:02:07 hello! Jul 13 02:02:14 quick question Jul 13 02:02:29 i wanna enable serial on UART4 Jul 13 02:02:51 jsarman: thx for the tips. i`m off to zz 5AM here Jul 13 02:02:52 i was wondering if its possible with the ftdi cable plugged in Jul 13 02:03:01 havea a great day/night on ur part of the world! Jul 13 02:03:30 well tty04 Jul 13 02:03:33 beaglebone black Jul 13 02:03:35 good night Jul 13 02:04:24 can i use UART4 if i have an ftdi cable plugged in? Jul 13 02:04:52 i tried using minicom to switch to serial to tty04. but when i run minicom i get a lockfile error Jul 13 02:04:56 guest I see /dev/ttyS3 on my BBB Jul 13 02:05:00 so you should Jul 13 02:05:32 hmmm this tutorial told me to swich it to tty04 Jul 13 02:05:46 serials are ttyS* Jul 13 02:05:55 0 indexed Jul 13 02:06:19 so UART4 == ttyS3? Jul 13 02:06:25 yep Jul 13 02:06:31 ... Jul 13 02:06:40 they didnt 0 index the UARTS i see Jul 13 02:07:06 it just something you TIL today I learned Jul 13 02:07:46 whenever i change the serial file in minicom setup Jul 13 02:07:50 if you had a pc rnning linux with serial port it woudl be ttyS0 Jul 13 02:07:52 it returns to ttr04 Jul 13 02:08:11 minicom is alway misconfigured first use Jul 13 02:08:13 tty04 Jul 13 02:08:24 what should i do? Jul 13 02:08:32 minicom Jul 13 02:08:36 Ctrl A Z Jul 13 02:08:39 0 Jul 13 02:08:43 setup serial Jul 13 02:08:57 change A to /dev/ttyS3 Jul 13 02:08:59 minicom -s Jul 13 02:09:05 brings up setup options Jul 13 02:09:05 change flowcontrol to nonce Jul 13 02:09:08 ok Jul 13 02:09:17 however you get there is fine Jul 13 02:09:40 erase all the modem init strings Jul 13 02:09:47 exit Jul 13 02:09:52 ctrl A Q Jul 13 02:09:54 minicom Jul 13 02:09:56 works Jul 13 02:10:23 * mranostay bikes in Jul 13 02:11:10 oh my bad do the save as dfl Jul 13 02:11:32 thanks. Jul 13 02:12:00 now im getting strange results. i cant see what i type but it is there and when i press enter everything starts slannting over Jul 13 02:12:16 baud problems Jul 13 02:12:39 set your baud rate Jul 13 02:12:45 then save as dfl Jul 13 02:12:49 ctrl A Q Jul 13 02:12:52 minicom Jul 13 02:13:10 you always have to restart minicom after changing settings Jul 13 02:13:30 thats the caveat Jul 13 02:13:53 i nevr got minicom to run. only minicom setup. minicom always said lockfile cannot be created. Jul 13 02:14:05 sudo minicom Jul 13 02:14:05 which setting allows me to change baud rate and what is the propper number? Jul 13 02:14:16 im on armstrong root. so no sudo Jul 13 02:15:00 ok well can't fix that Jul 13 02:15:28 if oyur root and cant create a file means filesystem is readonly Jul 13 02:16:24 the minicom file is .minirc.dfl Jul 13 02:16:24 hmmm i thought it was because i was trying to use UART4 while having the ftdi cable plugged in. Jul 13 02:16:39 nah Jul 13 02:17:10 I have used minicom several times on the omap 3530 on a custom board Jul 13 02:17:11 strange Jul 13 02:17:18 I set up a few Jul 13 02:17:23 they all worked fin Jul 13 02:17:24 i was trying to mimic this setup Jul 13 02:17:25 e Jul 13 02:17:25 http://www.armhf.com/wp-content/uploads/2013/06/bbb_serial_debug.jpg Jul 13 02:17:44 except i would have the pins go into UART4 on both devices Jul 13 02:17:53 since i can attach my pins to j1 Jul 13 02:18:01 cant* Jul 13 02:18:33 you need some molex female pins :) Jul 13 02:18:50 I have tons here :) Jul 13 02:19:00 lols. i have male to male. Jul 13 02:19:22 but taking those from UART4 on both devices should work though right? Jul 13 02:19:24 old PC's have em if you are willing to steal em Jul 13 02:19:59 in te jpeg the one bone is I guess uart4 Jul 13 02:20:04 the other is uart0 Jul 13 02:20:16 my setup has both with uart4 Jul 13 02:20:16 aka debug port Jul 13 02:20:26 Hi, I am working on BBB with OpenCV. I face an issue with the windowing issue. Doing the simplest OpenCV Hello World Sample Window does not work. Jul 13 02:20:43 you got a baud rate flow control issue Jul 13 02:20:53 how do i set the baud rate? Jul 13 02:21:00 minicom :) Jul 13 02:21:05 A thread is created, but no solution yet. https://groups.google.com/forum/#!topic/beagleboard/rIkQYTEFrEI Thanks Jul 13 02:21:06 or setserial Jul 13 02:21:15 i didnt see the option in the setup... Jul 13 02:21:26 minicom Jul 13 02:21:33 Ctrl A then Z Jul 13 02:21:35 then o Jul 13 02:22:40 E Jul 13 02:22:44 wont even open. just closes once it says the lockfile can't be created. but you have been more than helpful. Jul 13 02:22:54 i guess i will need to learn a bit more. Jul 13 02:22:58 delete your .minirc.dfl file Jul 13 02:23:04 ok. Jul 13 02:23:15 hmm do you know the directory? Jul 13 02:23:26 ~/.minirc.dfl Jul 13 02:30:10 Hello just got the beaglebone black today and am having some trouble imaging linux unto it. I have the file to image it and 7zip but now am unsure where to go from here. Any help would be greatly appreciated. Jul 13 02:30:56 finally got minicom to open. Jul 13 02:31:46 nice Jul 13 02:32:04 angrycoast: just start plying with it Jul 13 02:32:17 you dont have to image it yet Jul 13 02:32:33 im one step closer now. thanks jsarman Jul 13 02:32:36 im taking a break now. Jul 13 02:32:48 may the Lord give you a double blessing for helping me. Jul 13 02:32:56 I want to be able to use Python Jul 13 02:32:59 too bad szhao couldnt find help like me. Jul 13 02:33:08 im new Jul 13 02:33:15 to the irc Jul 13 02:33:29 true but you were on at the right time to help me. Jul 13 02:33:46 plenty others watching but already tired of helping Jul 13 02:34:05 dont blame them. you get worn out quick by scrubs like me. Jul 13 02:34:12 I dont. Jul 13 02:34:42 good to know. see ya around Jul 13 02:34:43 In fact one of the possible watchers invented all this Jul 13 02:34:52 oh Jul 13 02:34:55 nice. Jul 13 02:34:56 in the 80's 90's Jul 13 02:35:17 the true master may be watching us talk Jul 13 02:35:49 we all have our domains Jul 13 02:36:08 if curious just search Apple newton Jul 13 02:36:47 yep. night for now. unless i get kicked in the ribs by this. Jul 13 02:40:53 holy crap! working with GPIOs on BBB is like pulling teeth compared to BBW. Jul 13 02:43:52 is there an easy way to set mux mode other than creating these stupid DTS files? what a NIGHTMARE! What ever happened to the /sys/kernel/debug/omap_mux Jul 13 02:45:26 SeeMitchPlay: pincontrol came around Jul 13 02:49:56 mranostay: https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-prn2/1039923_10151727544377661_1671696228_o.jpg Jul 13 02:50:05 output from the Bcc fpga Jul 13 02:52:11 mrpackethead: dmx512 i assume? :) Jul 13 02:52:17 yes. Jul 13 02:52:21 thats a logic16 decoding it Jul 13 02:52:31 nice Jul 13 02:53:18 mranostay: making it damn near impossible to write a simple script to blink an LED? Jul 13 02:55:21 no it isn't Jul 13 02:56:06 http://hipstercircuits.com/capture-input-events-via-gpio-on-beaglebone-black/ <-- that's how they say to mux a pin Jul 13 02:56:34 vs a simple "echo 7 > omap_mux/gpmc_ad6" Jul 13 02:57:25 yeah problem is it sucks for a real driver :) Jul 13 02:58:08 well drivers does not a simple script make Jul 13 02:58:28 Does anybody use OpenCV on BBB encountered windowing issues? Jul 13 02:58:46 szhao: when is your homework due? **** ENDING LOGGING AT Sat Jul 13 02:59:58 2013
