**** BEGIN LOGGING AT Mon Mar 24 02:59:59 2014 Mar 24 03:01:00 I've flashed mine 3 times today :D. This should be the last one though (making a personal dropbox using owncloud) Mar 24 03:02:17 i am at a complete loss here Mar 24 03:07:47 is there even anyone in here Mar 24 03:08:31 might help to ask your question instead of being vague Mar 24 03:08:55 well some sort of sign of life is always a good start Mar 24 03:09:35 What PurpleDog said Mar 24 03:09:57 when i use cloud9 ide i can use any preloaded code with no problem but when i attempt my own code or any code from anyone elses site then i lose connection with my board Mar 24 03:10:25 (1:38:57 PM) psyko: well some sort of sign of life is always a good start <--- reading the topic on entry is an even better start..... but you know.... Mar 24 03:11:20 ohh my bad what ever was i thinking that a chat room would be doing anything like chatting. Mar 24 03:12:27 apparently this is one of those rooms where people just sit around waiting on someone to come along looking for help and then they can just start mouthing off like a stupid little 12 year old and not actually address any real problems Mar 24 03:12:39 <_Aqua> ;) Mar 24 03:13:04 loooool Mar 24 03:13:19 good luck with your problems with an attitude like yours :) Mar 24 03:13:32 <_Aqua> well he isn't wrong. Mar 24 03:14:03 says someone who only just entered said room..... good work champ Mar 24 03:14:17 <_Aqua> case proven right there. Mar 24 03:14:21 an attitude like mine. I was looking for some body that would be talking instead of a bunch of bots or idiots that forgot to sign off but the first response couldnt be hello or hey man whats up Mar 24 03:15:01 dan1 how old are you and what is ur actual experience with the board Mar 24 03:15:58 guessing by your attitude... im old enough to be your father Mar 24 03:16:11 and been playing with embedded boards for a few years now Mar 24 03:16:23 ill be flat out honest here. im 28. computer engineering student looking to learn on my own and having problems that i can not solve in a rather crappy FAQ and Beagle is less than a week old to me Mar 24 03:16:26 <_Aqua> haha... this is just funny ppl. Mar 24 03:17:00 so i am old enough to be your father :) Mar 24 03:17:01 lol Mar 24 03:17:16 dan1 if all you can do is mouth then shut the hell up Mar 24 03:17:37 but its fun trolling morons.... Mar 24 03:18:23 so... if your old enough to be my father then that means your sorry ass would be cake walk in person and what person over the age ohh say 20 would go into chat rooms looking to "troll" Mar 24 03:19:17 <_Aqua> psyko, what are you needing help with? they'll be as repetative as moth flying into the light... it's called low self-esteem with a big ego that needs attention. Mar 24 03:20:26 i keep losing my board connection when i use the cloud9 ide. is there not some way to download the ide for offline use and am i just flashing the eeprom or will my code stay when i turn off the power Mar 24 03:20:41 <_Aqua> *waiting* for the improper grammer response. Mar 24 03:21:27 i have had too much to drink for proper grammar use lol Mar 24 03:21:30 <_Aqua> I usually ditch cloud9 and use eclipse with remote ssh. Mar 24 03:21:47 <_Aqua> less overhead on the bbb. Mar 24 03:21:53 ok cool Mar 24 03:22:25 <_Aqua> https://www.eclipse.org/ Mar 24 03:22:32 do you know of a good tutorial? Mar 24 03:22:46 ive used eclipse in class so its already on my comp Mar 24 03:23:37 <_Aqua> derek molloy has some good video's on using eclipse if you wanna watch 45 mins of babble. Mar 24 03:23:39 <_Aqua> http://derekmolloy.ie/beaglebone/setting-up-eclipse-on-the-beaglebone-for-c-development/ Mar 24 03:24:09 also i was told that the beagle was linux language but everything i have found seems to be more c based. I dont know crap on linux is it like linux or was i told wrong Mar 24 03:24:33 <_Aqua> or just basically go into eclipse and add a new connection, pretty straight forward. Mar 24 03:24:47 <_Aqua> you can use python script... Mar 24 03:24:59 <_Aqua> adafruit has a nice bbio library. Mar 24 03:25:40 hold up isnt eclipse more of a java ide? Mar 24 03:25:56 <_Aqua> nope, it's just about every language. Mar 24 03:26:04 <_Aqua> just gotta install the plugins for them. Mar 24 03:26:28 <_Aqua> it's built off of java I believe. but I do c++, html, python... etc. etc. no probs. Mar 24 03:27:01 sounds awesome _Aqua 10 points for not being a deuche Mar 24 03:28:57 *douche Mar 24 03:29:11 cant even get that right.... Mar 24 03:29:37 <_Aqua> see, that's about all they all know how to do. Mar 24 03:30:21 <_Aqua> what's the point of fuckin pointing this shit out Dan? fuckin moron. Mar 24 03:30:42 im the moron? haha Mar 24 03:30:47 go fuck yourself champ :) Mar 24 03:30:49 <_Aqua> yeah, actually... you are.. Mar 24 03:31:02 <_Aqua> feel bigger now? Mar 24 03:31:25 not in the slightest Mar 24 03:31:48 just hate fuktards Mar 24 03:31:55 <_Aqua> then quit being one. Mar 24 03:32:07 "i know you are" Mar 24 03:32:17 <_Aqua> yeah, this is your game... I'm just playin it with yeah. Mar 24 03:32:34 its a game now? Mar 24 03:32:36 his mom is obviously helping on his comebacks at this point Mar 24 03:34:29 _Aqua: maybe if you had some clue of where this whole thing started... rather than coming in at the end of it you wouldnt be coming across the same way Mar 24 03:34:59 but thats ok, your comfortable in your smugness, i get it Mar 24 03:35:02 <_Aqua> nah, I can see the truth. typical day in the ole'bbb community. Mar 24 03:35:15 you obviously cant see shit Mar 24 03:35:29 <_Aqua> haha... you're funny man. Mar 24 03:35:36 but hey, i know a lot of people who love to live in denial Mar 24 03:35:52 <_Aqua> it's like here reflecting on his own mind or something. Mar 24 03:35:59 <_Aqua> here/he's Mar 24 03:36:01 dan1 put the cheetos down and venture out into whats called the real world Mar 24 03:36:27 actually its a mushroom Mar 24 03:36:36 and i will be as soon as im finished lunch Mar 24 03:36:58 but hey, keep up the good work Mar 24 03:37:11 if its shrooms u wouldnt go near the comp afraid the keys were lava and the screen would eat u Mar 24 03:37:38 nope, swiss brown i believe Mar 24 03:38:08 seems every step your wrong so far Mar 24 03:38:25 still placing money ur a fatty that lives with mommy Mar 24 03:38:45 * Dan1 has already pointed out im old enough to have been your father Mar 24 03:39:09 doesnt mean u have reproduced Mar 24 03:39:17 or moved out Mar 24 03:39:26 maybe your mistaking "my mother" with "a mother"... seems your guessed have been wrong the whole way Mar 24 03:40:47 as for being a fatty, im australian dumbarse, its only you americans with that problem Mar 24 03:41:13 but i notice u havent actually addressed anything related to the board so u must b a poser? Mar 24 03:41:33 u admit ur an australian dumbass? Mar 24 03:41:35 fuck another swing and a miss.... Mar 24 03:42:14 i m american but obesity isnt my prob Mar 24 03:42:17 just because i didnt waste my time on you dosnt mean i havnt helped others... just means i think your a fuktard and beneath my help Mar 24 03:42:47 <_Aqua> holly guys... I'm outta here... enjoy. Mar 24 03:42:50 caus in fact... the very first thing i said to you was enough help to solve your problem Mar 24 03:42:52 beneath u? wow egotistical much? Mar 24 03:43:18 but your to fucking stupid to have realised Mar 24 03:43:53 id call that feeling entitled Mar 24 03:43:58 ur too dumb to spell right (since u wanna point out my misspellings) Mar 24 03:44:04 which is fairly typical for a yank... Mar 24 03:44:39 no, i pointed out your misspellings caus if your gonna insult me at least try and show some intelligence :P Mar 24 03:44:42 no yank here so come on down to the south a see a real country boy Mar 24 03:45:10 lol "south" Mar 24 03:45:23 explains a lot Mar 24 03:45:56 does it? cause u would b using ur manners round here boy Mar 24 03:46:15 wow... just.... wow Mar 24 03:46:26 your amazing Mar 24 03:46:28 really Mar 24 03:46:34 i know i m Mar 24 03:46:50 you are exactly the reason the civilised world hates america Mar 24 03:46:54 lol Mar 24 03:47:18 no see u got the wrong info there Mar 24 03:47:26 the absolute epitome Mar 24 03:47:55 go study ur politics and see how many southeners are the " epitome" of what the world dislikes of america Mar 24 03:48:24 my politics? or yours? Mar 24 03:48:31 i know enough of both already thanks Mar 24 03:48:50 politics in general, its called world politics Mar 24 03:49:00 i highly doubt it Mar 24 03:49:33 have you got any actual idea what your talking about? Mar 24 03:49:53 or just heard it on late nite tv one nite and thought you would try and sound intelligent? Mar 24 03:50:19 caus you just come across so stereotypical to me Mar 24 03:50:27 were a bunch of bible thumpin gun toting self dictating "rednecks" that will put a bullet in u if u even think to cross our freedom Mar 24 03:50:48 looooool Mar 24 03:51:05 cant tell if stupid or... well... no just stupid Mar 24 03:51:29 do the research of how many southeners have actually put up with anyones bullshit Mar 24 03:51:41 bwahahaha Mar 24 03:51:45 seriously dude Mar 24 03:51:47 stop it Mar 24 03:51:49 your killin me here Mar 24 03:52:02 can barely see through the tears of laughter Mar 24 03:52:08 ur no australian i can tell that Mar 24 03:52:24 born and bred Mar 24 03:52:39 maybe bored and inbred Mar 24 03:52:41 6th generation or something..... quite the "first fleeter" as people say Mar 24 03:52:51 isnt that you southerners? Mar 24 03:52:56 all fucking your sisters? Mar 24 03:53:11 6th gen gets u abilty to claim ur an aussy? Mar 24 03:53:18 oh, you thought i didnt know that either i guess? Mar 24 03:53:33 you claiming your 'mercan? Mar 24 03:53:40 didnt realise you were native..... Mar 24 03:53:48 so ur best comeback is an internet joke? Mar 24 03:54:18 which part is an internet joke? keeep up son your to slow Mar 24 03:54:23 ive got quite a bit of indian in my blood too Mar 24 03:54:39 ur the internet joke Mar 24 03:54:56 lol Mar 24 03:55:00 "quite a bit" Mar 24 03:55:28 dude, your just a joke from beginning to end.... one that dosnt have a punch line Mar 24 03:55:53 anyways im done with ur ssorry excuses and ive got my shit to workin now. hope you have fun with ur pathetic life and tell your mom hi for me Mar 24 03:56:12 the closest thing to a punch line you got is what your daddy does to your mommys face every nite Mar 24 06:18:47 I am getting a error select timeout when using a 640x480 webcam to capture video Mar 24 06:18:59 can someone help? Mar 24 06:20:30 does the webcam work on a linux desktop? Mar 24 06:20:39 yes Mar 24 06:21:39 Sorry we haven't tried in linux we have tried it in windows only. Mar 24 06:25:56 well, then make it work on a desktop linux first Mar 24 07:43:55 Hi !! Suppose I make a prototype of a wearable device using a beaglebone. How would i miniaturize it to something that is actually wearable ? Mar 24 07:44:59 miniaturise the BBB? or the rest of the stuff you would need to make it work? Mar 24 07:45:15 leave out everything that you don't need, use smaller packages, etc. Mar 24 07:46:56 Oh Mar 24 07:46:59 or hire someone who knows how to miniaturize electronics... like us, for example Mar 24 07:47:04 or just define a backpack as "wearable" Mar 24 07:47:50 yeah, or cough up a few 100k$ and tell $PEOPLEWHOKNOWTHEIRJOB what you would like to have Mar 24 07:47:59 haha....I'm still working on it !! I'm also looking at Flora from Adafruit Mar 24 07:48:29 in what way ist that comparable to a BBB? Mar 24 07:48:30 I went to a lot of trouble for the 45$ for a black :| Mar 24 07:49:49 ok. so what are you actually expecting us to tell you? Mar 24 07:50:30 Ok..I guess it was a stupid question ! Mar 24 07:53:06 not stupid per se, but showing a lack of understanding ;) Mar 24 07:53:35 electronics miniaturization is easy. especially today. but you need to know what you are doing. and most people don't Mar 24 07:54:05 Been a web dev guy for a long time...just venturing into hardware :) Mar 24 07:54:47 what kind of hardware? Mar 24 07:54:59 doing electronics design? or just programming embedded hardware? Mar 24 07:56:33 programming Mar 24 07:59:00 that's easy Mar 24 07:59:20 you just need to have a very good understanding of linux, especially the low level stuff. Mar 24 08:19:09 hi to all, i have a question Mar 24 08:19:14 ask Mar 24 08:19:23 or even Mar 24 08:19:24 http://www.catb.org/esr/faqs/smart-questions.html Mar 24 08:19:51 i need to clone the internal memory of my bbb into another Mar 24 08:20:59 why? Mar 24 08:21:03 how can i make an image like armhf images? Mar 24 08:21:17 dd Mar 24 08:21:32 login over ethernet Mar 24 08:21:40 dd if=/dev/mmsd* of=your_file Mar 24 08:21:51 /dev/mmcsd or similar Mar 24 08:23:17 i think i have to do with a live system Mar 24 08:25:52 ? Mar 24 08:33:17 pablognu: you can mouunt the rootfs RO (edit /etc/fstab) then your dump from a live system is even consisten Mar 24 08:33:20 t Mar 24 08:34:10 pablognu: but maybe ist easier to boot from an sdcard and dump the eMMC to that card Mar 24 08:36:04 you can still dump it to the PC directly Mar 24 08:57:24 If i want a debian on my beaglebone without all the beagle services preinstalled, can I use the standard arm image by debian and still use GPIO? Mar 24 09:06:19 brainvoid: you can use a debian image for bbb Mar 24 09:06:28 brainvoid: and you can deinstall all the "standard services" Mar 24 09:06:41 brainvoid: dpkg -P is your friend Mar 24 09:21:27 yeah that sounds lot easier than starting from the standard image Mar 24 09:21:56 you can spkg -d and then save your image for future use Mar 24 09:22:05 dpkg* Mar 24 09:46:25 Does anyone know of a large touch screen (preferably 15" or larger) that is compatible with the BBB? (I found this (http://shop.udoo.org/eu/accessories/video-kit-15-6-lvds.html) but I'n not sure if it is compatible and I think that is rather a high price for my tight budget. Mar 24 09:50:13 http://www.amazon.com/Dell-E2014T-Screen-LED-Lit-Monitor/dp/B00FE8MLY6 Mar 24 09:50:17 KotH, jules: thanks for that =) Mar 24 09:53:55 av500: Oh, I didn't think of that market yet. Thanks! Mar 24 10:28:18 Hello everybody, on small question: Has anyone tested the BBB in terms of vibration (with a shaker)? Mar 24 10:28:53 it's not certified for vibration, if you mean that Mar 24 10:29:52 yep, but did anyone try to test it - I don't need a certification, just want to make shure, it is not disassembling, when used on a small uav... Mar 24 10:33:18 where can I find information on potenially performed vibration testing? Mar 24 10:35:28 not certified means that you cannot be sure whether a board surivives vibration or not Mar 24 10:35:47 the whole production process is not controlled in that regard Mar 24 10:36:05 you can have one lot that is fine under heavy vibration, while the next one falls appart when you touch it Mar 24 10:37:01 if you want to use the bbb in any application that is vibrating, you are on your own Mar 24 10:37:07 it might work, or it might not Mar 24 10:37:11 depending on your luck Mar 24 10:37:29 if you want to ensure stability, pot the whole board in epoxy Mar 24 10:37:53 ok, I understand - but does that mean, no one tried to shake an "average" BBB in terms of vibration? Mar 24 10:37:59 but make it glass filled epoxy to ensure thermal conductance Mar 24 10:38:06 yes Mar 24 10:38:14 hey Mar 24 10:38:24 Thats a good hint - thanks for the explanation!! Mar 24 10:38:30 if vibration is a requirement, then you have to design for it Mar 24 10:38:40 otherwise vibration testing is just a waste of money Mar 24 10:39:16 bbb_ef: what is your application and what do you want to use the board for? Mar 24 10:39:24 uav Mar 24 10:39:38 yet another german uav attempt? Mar 24 10:40:42 we try to build up an experimental flight control computer for a small uav project... Actually it should be of no great damage, if the computer fails, as we are secured below a main fcc... Mar 24 10:41:41 we just want to use a powerful general purpose system (cheap and flexible) in order to try different control law features... Mar 24 10:42:46 eh... Mar 24 10:43:01 i really hope you have a good backup system Mar 24 10:43:10 we are not trying to get systems fulfilling MiL-STD810C are similar, just a "robust" system, that is yet flexible... Mar 24 10:43:20 bbb_ef: there are vendors that will sell you BBBs or similar things with all funny kinds of testing/certification. Mar 24 10:43:41 bbb_ef: maybe just talk to circuitco. Mar 24 10:43:54 bbb_ef: oh.. and get a good insurance Mar 24 10:44:18 we're going to do that:-)) Mar 24 10:44:22 bbb_ef: if an uav goes out of control and crashes into anything, you will have a hard time explaining why you have not used flight certified components Mar 24 10:45:17 KotH: That issue is covered by our "outer shell" fcc - we should be free to do anything a given - small - envelope Mar 24 10:45:26 bbb_ef: fcc? Mar 24 10:45:34 flight control computer Mar 24 10:46:09 bbb_ef: it will not matter whethe the bbb was the problem or not. it's enough that it's in there and connected to the control system Mar 24 10:47:21 we're building some extra base board for the BBB featureing issues like galvanic separation, further interfaces, power outages... Mar 24 10:47:40 bbb_ef: university project or industrial? Mar 24 10:47:50 academic Mar 24 10:48:16 then you might be lucky and get just a fine ^^' Mar 24 10:48:28 :-)) Mar 24 10:49:38 but seriously: flying any electronic that is somehow connected to critical systems needs a lot of paperwork to get certification. i dont know what the legal situation regarding uavs in germany is, but i guess they are as strict as in the rest of europe Mar 24 10:50:33 and just for reference: doing a medical implant is easy and straight forward compared to do anything aerospace related. the paperwork is humongus. certifications difficult at best.... Mar 24 10:51:39 You are right, but we think that our concept (outer shell) should be capable of mitigating the risks. We are not going to do anything like a full certification like EASA C-25/23 etc. Mar 24 10:52:23 Galvanic isolation ! ... also of the power supply ? Mar 24 10:52:34 teralaser: that's standard practice Mar 24 10:52:52 yes, onboard microwave transmitter and receiver Mar 24 10:52:52 not on the BBB Mar 24 10:53:32 Going to introduce a respective DCDC converter Mar 24 10:53:43 "respective" ? Mar 24 10:53:50 a flyback? Mar 24 10:54:53 * teralaser is using Linear's LT3748 series, but if you find something, please let me know. Mar 24 10:54:56 teralaser: galvanic isolating supplies can be bought of the shelf Mar 24 10:55:03 Not really a fan of the mandatory load thing Mar 24 10:55:10 eh.. Mar 24 10:55:21 real world sucks, doesnt it? Mar 24 10:56:26 a DCDC converter with the capability to cover minor power outages - your Linear LT3748 looks promising! Mar 24 10:57:44 :) Mar 24 10:58:35 bbb_ef: all DC/DC switching converters can do that Mar 24 10:58:39 KotH, LetoThe2nd, teralaser: Thanks for your input and discussion! Unfortuantely have to quit now... Mar 24 10:58:41 bbb_ef: it's part of their working principle Mar 24 10:59:03 bbb_ef: actually, it works even with LDOs Mar 24 10:59:18 bbb_ef : Cya Mar 24 10:59:44 bbb_ef : Use a low-impedance FET instead of a diode ... insider tip :P Mar 24 11:04:29 teralaser: a fet? Mar 24 11:04:40 teralaser: how do you replace a diode by a fet? Mar 24 11:05:44 reverse a P-ch FET and control the gate when you want to work as a diode Mar 24 11:05:50 +it Mar 24 11:05:54 ANYWAYS, lab time Mar 24 11:07:03 teralaser: yes, how do you control the gate? Mar 24 11:21:53 KotH : well the simplest way is to just to put the G to the D pin. For a flyback/battery/... solution you can use other controls Mar 24 11:23:46 and then of course it can go infinitely advanced like a bridge of FETs http://www.electronicsweekly.com/news/design/power/in-depth-linear-technologys-active-bridge-rectifier-2013-06/ Mar 24 11:28:18 Can anyone suggest a decently built (inside), and cheap (or at least not overpriced) 7-port USB hub? Mar 24 11:35:28 google? Mar 24 11:37:50 Sadly most sellers don't show PCB shots. :-/ Mar 24 11:55:36 ZiNC: I use a D-Link one, it seems to work pretty well: http://www.amazon.co.uk/D-Link-DUB-H7-Port-USB-External/dp/B0002AFZVM/ref=sr_1_1 Mar 24 11:56:39 I'd assume D-Link would have a decent circuit in there. Mar 24 11:56:42 But too expensive. :) Mar 24 11:57:31 (And not the physical layout I'm after, but I think the chances of finding both the layout and good design are slim.) Mar 24 11:57:43 teralaser: rotfl Mar 24 11:57:55 teralaser: that will not work like a diode, not at all Mar 24 11:57:59 dwatkins: Have you opened it up to look inside? Mar 24 11:58:20 teralaser: you need active control of the fet Mar 24 11:58:55 ZiNC: no Mar 24 12:00:25 Why doesn't some hobbyist sell well designed USB hub PCBs? :) Mar 24 12:01:19 ZiNC: why do you care how the usb hub looks inside? Mar 24 12:01:35 I'm more concerned with how well it works, and mine works fine. Mar 24 12:01:38 Because I want it safe. Mar 24 12:01:46 in fact, I have two. Mar 24 12:01:46 ZiNC: and it's cheap, well build and available... choose one of those three Mar 24 12:02:08 ZiNC: buy an industrial usb hub. or a medical one Mar 24 12:02:12 ZiNC: they are safe Mar 24 12:02:22 dwatkins: It depends also on the devices you connect to it, usage, randomness, etc. A $3 hub could function just fine in many cases. Mar 24 12:02:49 KotH: The difference between a good/safe hub and a cheap one is what, 1-2$ of parts? Mar 24 12:03:07 ZiNC: no, the parts are the same Mar 24 12:03:13 This divide of cheap $4 hubs, then $30 ones is annoying. Mar 24 12:03:20 ZiNC: the difference is in the design, production and how well they are build Mar 24 12:03:32 ZiNC: oh.. and post production control Mar 24 12:03:38 KotH: Nah. The cheap ones would skimp on capacitors, not to talk about overvoltage/current/ESD protection. Mar 24 12:04:05 there aint no overvoltage/current/esd protection in consumer hardware Mar 24 12:04:39 Sure there is. Why not? Mar 24 12:04:39 it's too expensive Mar 24 12:04:49 What, a little chip from TI, or a few diodes? Mar 24 12:04:58 that's >0.01$ Mar 24 12:05:14 How do you define "consumer" hardware? :) Mar 24 12:05:37 in cosumer hardware, people try hard to save 10^-3 usd Mar 24 12:05:47 That D-Link hub is probably fine. Mar 24 12:05:55 stuff like usb hubs, that are build in the millions/year Mar 24 12:06:09 Though I get the feeling the USB data lines don't always get protection, for some reason. Mar 24 12:06:21 as i said, protection chips are expensive Mar 24 12:06:23 yeah, I'd go with a D-Link product over a Belkin one. Mar 24 12:06:24 you dont put that in Mar 24 12:06:32 people usually dont touch those Mar 24 12:06:38 hence no protection "needed" Mar 24 12:06:55 KotH: you're sounding like a sex-ed lecture Mar 24 12:07:12 honestly, i am a sex-ed lecture Mar 24 12:07:34 So I should focus elsewhere. Mar 24 12:08:06 Where one can find a good PCB design for a 7-port hub? :) Mar 24 12:08:17 2 layers, if possible. Mar 24 12:08:50 ZiNC: http://www.exsys.de/index.php?page=product&info=51 Mar 24 12:08:53 ZiNC: get one of these Mar 24 12:08:54 If small, 10 PCBs for $15 is quite nice. Mar 24 12:09:13 do you want to build an usb hub yourself? Mar 24 12:09:22 SMD soldering might pose some problem, but it's doable. I suppose. Mar 24 12:09:51 That'd be interesting, yeah. Mar 24 12:10:08 I'm not qualified, but if the PCB is already layed out... who knows. Mar 24 12:10:10 it'll cost you more than the exsys hub Mar 24 12:10:11 much more Mar 24 12:10:15 Why? Mar 24 12:10:22 you dont buy millions of parts Mar 24 12:10:30 you wont get the parts cheap Mar 24 12:10:31 You don't have to. Mar 24 12:10:35 and NRE is not as low as you think Mar 24 12:10:42 Besides the PCB, the main cost is the controller. Mar 24 12:10:49 So I'll pay $6 for a USB2517 instead of $3. Mar 24 12:10:52 no, it's the PCB Mar 24 12:11:09 even a small PCB is >10$ in single quantities Mar 24 12:11:10 What, production? Mar 24 12:11:18 yes Mar 24 12:11:33 10x5cm is quite cheap. Mar 24 12:11:49 Even 4 layer might be okay. Mar 24 12:12:34 unless you know what you are doing, you will need 4 layers or you will have serious EMI problems Mar 24 12:12:43 And hey, maybe there's some market for assembled well designed USB hub boards? I know I'd want one. :) Mar 24 12:12:53 mayhe Mar 24 12:12:58 maybe Mar 24 12:13:00 look in china Mar 24 12:13:01 Does it matter if you don't care about FCC/CE/whatever? Mar 24 12:13:08 but be prepared to buy 1000 of them Mar 24 12:13:14 yes, it does matter Mar 24 12:13:26 In what ways? Mar 24 12:13:33 the use of non certified stuff is prohibited by law Mar 24 12:13:51 if you cause problems for other people, you will pay a hefty fine Mar 24 12:13:53 99% of the hubs on the market are not certified. Mar 24 12:13:59 they are Mar 24 12:14:06 they all have FCC/CE conformance Mar 24 12:14:22 otherwise they wouldnt be allowed to be sold Mar 24 12:14:37 oh. and they are checked by the authorities from time to time Mar 24 12:14:59 ZiNC: let me guess, you've never done electronics design, have you? Mar 24 12:15:12 No. Mar 24 12:15:23 yappari Mar 24 12:15:45 Anyway, I'd expect D-Link or Belkin or whatever to be, Mar 24 12:16:01 take my word for it: it's not as easy as writing software, and there are thousands of boobytraps that will get you. some of which you will not notice until much later Mar 24 12:16:17 but $5 hubs that skimp on solder? Mar 24 12:16:46 I'm sure there are many things to consider and do. Mar 24 12:17:07 That's why an existing PCB layout. :) Mar 24 12:17:31 What about USB1 vs USB2, BTW? Mar 24 12:17:39 hi! Mar 24 12:17:57 Hi. Mar 24 12:18:53 KotH: E.g., http://www.george-smart.co.uk/wiki/Cheap_CCY-01_USB_Hub Mar 24 12:18:54 ZiNC: that are protocol differences Mar 24 12:18:59 I mean EMI-wise. Mar 24 12:19:02 and 2 layers. Mar 24 12:19:08 ZiNC: i doubt that you will find stuff that are only USB1.x compliant Mar 24 12:19:18 ZiNC: everything should be at least 2.0 if not 3.0 compliant Mar 24 12:20:13 ZiNC: FCC/CE compliance does not mean the device works as advertized ;) Mar 24 12:20:22 ZiNC: If it is important, it always works, look for the red-blue USB certificate Mar 24 12:20:47 Red blue? Mar 24 12:21:11 http://commons.wikimedia.org/wiki/File:Certified_Hi-Speed_USB.svg Mar 24 12:21:23 KotH: I guess if you don't connect the ports anywhere you're likely to have less emission. Mar 24 12:21:35 there is also a superspeed version Mar 24 12:22:09 But stickers are almost as cheap as diodes. :) Mar 24 12:22:25 ZiNC: exactly :) Mar 24 12:22:46 ZiNC: the sticker is not a bad idea Mar 24 12:22:47 you can only attach that sticker if you make a certain series of tests Mar 24 12:23:13 ZiNC: put that sticker on a product that isnt actually usb compliant, and you'll have a million lawyers hunting you donw Mar 24 12:23:15 (maybe some cheat of course... or don't know they can't use it unless they tested) Mar 24 12:23:28 Of course that's the idea. Mar 24 12:23:48 And a million lawyers would be a drop in the ocean in China. :) Mar 24 12:26:49 I doubt there are armies of lawyers who bother to hunt down fly-by-night shanzhai usb hub makers Mar 24 12:27:41 On second thought, that's a small geographic region with a high concentration of manufacturers. Might be easier to handle. Mar 24 12:35:59 ZiNC: .cn internal stuff is not a problem, nobody cares about them (too much a hazle and too little gain). but as soon as they start to export into western countries, they get hunted down Mar 24 12:37:43 Even besides direct sales on the internet, you do see these sorts of products in retail, at least in some countries. Mar 24 12:39:25 * av500 throws usb hubs at DJWillis Mar 24 12:39:58 I wonder what this might be: http://www.frys.com/product/5713722 Mar 24 12:44:28 If certified, and if this might imply better design, maybe there's hope. Mar 24 12:49:53 ZiNC : No separate power ? Mar 24 12:50:00 certified? Mar 24 12:50:05 * honestly snugs Mar 24 12:50:15 disregard that. Mar 24 12:50:36 teralaser: Dunno. Maybe there's something on the board directly. Mar 24 12:50:45 av500: Not? Mar 24 12:51:01 what is certified? Mar 24 12:51:33 It defends on what you connect. If you want to charge 4 Android phones e.g. , it is probably better with a separate power supply for the hub Mar 24 12:52:26 PRU experts: what am I missing to set up R30 as pru_r30_xy output? works in mode 7 as ARM GPIO, set to mode 5 for PRU. any more PRU internal settings required? Mar 24 12:52:29 teralaser: Sure. Mar 24 12:53:06 av500: If we assume large US retail stores only carry FCC approved stuff. Mar 24 13:02:19 ZiNC: yes, they all have CE/FCC Mar 24 13:02:32 though that does not garantee it works properly Mar 24 13:09:30 Are there any binary SPL builds for am335 around online? All searches point to building one yourself. I have done that, but get different behavior on different hardware. Trying to determine if it's a HW or SW fault. Mar 24 13:20:47 miken: there are binaries for the beagleboard and bone Mar 24 13:35:32 Anyone know when the IRC logs come out? I asked a question yesterday, got disconnected, and don't want to ask again if it was answered :-/ Mar 24 13:37:27 droidicus: if you were disconnected, then it has not been answered Mar 24 13:37:37 this is not mail, after all Mar 24 13:39:25 av500: found some ti binaries DL on http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html , will give it a try. Mar 24 13:39:58 it's not a BBB but it's still cooler then the BSD toaster, http://ovens.reviewed.com/news/some-dude-hacks-microwave-puts-manufacturers-to-shame?utm_source=taboola&utm_medium=cpc Mar 24 13:40:00 what's an SPL? Mar 24 13:40:11 Koth: oh I know, what I meant to say was that I was AFK for a couple hours, and chrome crashed on me before I could check the freenet web client Mar 24 13:40:21 a typo maybe ment to type SPI? Mar 24 13:42:12 av500: hm. they were for flash boot. Do you know of any bootloader bins, that load from uart? U-boot SPL for example. All prebuilt bins I found, are made to run from flash. Mar 24 14:01:24 miken: compile one from source Mar 24 14:01:31 mainline uboot is fine for BB and BBB Mar 24 14:04:29 whats a good way to control my beaglebone black through a bluetooth android app? and is there a recommended application? I want to use my phone as a gamepad to control the beaglebone black that will then also be controlling an arduino nano v3 through i2c which controls a rc car. Any recommendations on a client and how to control the beaglebone through bluetooth Mar 24 14:05:54 http://forum.xda-developers.com/showthread.php?t=1501060 Mar 24 14:05:59 (random google) Mar 24 14:06:06 av500: have already built on. It just only works on some of my hw, so wanted to try an 'official build', if there exists such. Mar 24 14:06:41 most official builds are form sd/mmc boot Mar 24 14:07:02 https://code.google.com/p/bluetooth-remote-control/ Mar 24 14:19:56 Did you see the Embest BBB? Mar 24 14:20:37 First time I see a Chinese replica that's more expensive than the original. :) Mar 24 14:20:59 But I guess it might be difficult to do other in this case. Mar 24 14:25:00 av500, u-boot is not fine..there is no spec Mar 24 14:25:14 mdp, +1 Mar 24 14:25:18 droidicus: just ask again Mar 24 14:25:29 mdp: i can write a spec Mar 24 14:25:33 mdp: if you need one Mar 24 14:25:43 the best specs are written from the completed s/w Mar 24 14:25:46 mdp: but it will cost you a lot of money to read it Mar 24 14:25:50 since u-boot is never done it is unpossible Mar 24 14:25:59 write a kernel spec Mar 24 14:26:22 KotH, I will d/l it from a .ru site for free Mar 24 14:28:22 Is the Embest variant an officially sanctioned one? Mar 24 14:29:25 yes Mar 24 14:29:33 did the Embest version add/change any features? Mar 24 14:29:39 I doubt it Mar 24 14:29:41 Is it just to add more production capacity? Mar 24 14:30:18 something like that Mar 24 14:30:46 Hmm... why doesn't TI give them good prices on the chip(s)? :) Mar 24 14:32:10 chip price is not everything Mar 24 14:33:01 If it's China-oriented it might be. Mar 24 14:33:59 ZiNC: unless you have extensive knowledge in building electronics in china, i would not talk too big Mar 24 14:34:10 Building? Mar 24 14:34:17 I mean the audience. Mar 24 14:34:28 ZiNC: especially not to people who work with china on a daily basis Mar 24 14:34:55 Just curious about the thing. Mar 24 14:36:36 i would guestimate that only something like a quarter of the retail price, or even less is chips Mar 24 14:37:26 I was looking up the prices a while back, Mar 24 14:37:39 I think the AM3358/9 was something like $28. Mar 24 14:37:47 nah Mar 24 14:38:07 And all the other components together were something similar. Mar 24 14:38:25 At least for a few thousands. Mar 24 14:38:47 Which was surprising given the retail of the BBB. Mar 24 14:39:51 $22 in 1k quantities, sayeth the budgetary pricing section on the product page Mar 24 14:40:08 do both have ethercat support or only 3359? Mar 24 14:40:27 ethercat need PRU IIRC Mar 24 14:40:32 and it's magic 'firmware' Mar 24 14:41:08 did we figure out how to compile and run programs on the pru yet Mar 24 14:41:11 panto: it also needs a licensing fee ;-) Mar 24 14:41:29 hence the 'magic' firmware Mar 24 14:47:14 myself: I think I looked at Digikey. Is the TI pricing a sort of manufacturer suggested price? Mar 24 14:47:29 digikey will always cost a lot more Mar 24 14:47:33 try searching octopart Mar 24 14:47:59 ignore public pricing for semiconductors Mar 24 14:48:20 Looks like the 3358 is closer to the TI pricing than the 3359. Mar 24 14:49:18 digikey has to make their profit when you buy from them Mar 24 14:49:18 For chips similar to this, or anything on Digikey/Mouser/etc.? Mar 24 14:49:58 the prices on ti's site probably assume that you are going to call your account rep and book a chunk of their production capacity Mar 24 14:50:17 and are a starting point for that discussion Mar 24 14:50:23 yes Mar 24 14:51:36 So the on-site prices for 1000-10000 are the same as MSRP in consumer shops? Mar 24 14:51:40 Silly. Mar 24 14:52:22 Does this apply also to basic components? Mar 24 14:55:12 the distributor can charge double because the items you buy from them have already been manufactured and are instock Mar 24 14:55:53 So these prices are only for emergency buys? :) Mar 24 14:56:21 the factories that make these things run backlogs of 4-25 weeks Mar 24 14:56:33 if you sent a PO your stuff would be scheduled at the end of the queue Mar 24 14:56:54 you'd also have to buy entire cartons/reels Mar 24 14:58:09 if you want piddly quantities or shipment from stock on-hand, you're going to pay more for the hassle Mar 24 14:58:24 budgetary pricing is so you can figure out what your mass-produced gizmo's BoM is gonna look like. Mar 24 14:58:49 How much of a difference would one expect for basic components? Mar 24 14:58:54 100% or more Mar 24 14:59:06 Even for simple passive things? Mar 24 14:59:27 Sure if you go to mouser and buy a 1000 ammo pack of resistors for $6 Mar 24 14:59:46 probably if you went to china and bought a carton of those ammo packs you could get 10x more for double that Mar 24 15:00:15 Same maunfacturer? Mar 24 15:00:31 mousers $6 ammo packs are generally house brand Mar 24 15:00:52 they hide the actual manufacturer Mar 24 15:00:54 And specific parts? Mar 24 15:01:36 depends on market conditions, if there is a shortage of something in stock then prices will go up Mar 24 15:02:51 never buy one of anything, if you can help it ;) Mar 24 15:03:17 Sometimes you only need 1. :) Mar 24 15:03:32 JFK, still no PRU docs? Mar 24 15:03:33 I share a lab with a bunch of friends (hackerspace) and we enjoy the power of buying in bulk.. it's pretty amazing Mar 24 15:04:00 myself: Buying 5 of anything? ;) Mar 24 15:04:07 ZiNC: i heard some people had some info, and i heard there were some details in earlier revs of datasheet Mar 24 15:04:43 ZiNC: 5 is appropriate for certain modules and higher-priced components. Passives always in qty.100 if we can :) Mar 24 15:05:01 when will you "not need" 5k resistors Mar 24 15:05:11 That's okay. Mar 24 15:05:12 bag of 2n3904s for a penny each, sure Mar 24 15:05:26 But what about 1000s of AM335x? :) Mar 24 15:05:50 JFK911: There are some docs available. Mar 24 15:06:28 im not ready to start until gcc has the pru as a target Mar 24 15:07:51 ZiNC: as said, ignore prices given by silicon manufacturers on their websites Mar 24 15:09:23 av500: I was expecting the stores to be closer to reality. If it can be less than even the mfgs' list prices, that's even nicer. Mar 24 15:09:57 JFK911: What do you plan to use it for? Mar 24 15:17:10 ZiNC: no plans yet, but if i had time and all the details i'd "play" with it Mar 24 15:19:09 For locally controlling some basic functionality assembly isn't too bad, though. Mar 24 15:21:18 ZiNC: you should go and work in electronics manufacturing for a while Mar 24 15:21:23 ZiNC: you'd learn a lot Mar 24 15:21:51 KotH: Could be interesting. Mar 24 15:21:58 But not long term. Mar 24 15:22:07 ZiNC: or if you know how to weild a soldering iron, as a soldering slave in an electronics design shop Mar 24 15:22:25 Less interesting. Mar 24 15:22:37 what is your background,btw? Mar 24 15:22:41 Software. Mar 24 15:22:46 web programming? Mar 24 15:23:02 Mostly C/++. Mar 24 15:23:09 In some cases some Java, sadly. Mar 24 15:23:18 what kind of c/c++? Mar 24 15:23:27 What kinds are there? Mar 24 15:23:38 many Mar 24 15:23:55 End-user software. Mar 24 15:24:49 gui? non-gui? medical? consumer? industrial? nuclear power plant control? Mar 24 15:24:59 If something I said upset you, I apologize. This wasn't the intention. Mar 24 15:25:12 dont worry, people in #beagle cannot upset me Mar 24 15:25:25 End-user as "consumer", I suppose. Mar 24 15:25:34 Yes, usually there's a GUI. Mar 24 15:28:37 PRU experts: what am I missing to set up R30 as pru_r30_xy output? works in mode 7 as ARM GPIO, set to mode 5 for PRU. any more PRU internal settings required? Mar 24 15:29:11 KotH: And yes, I've done some web, but I can't say PHP is my favorite thing. JS is rather cute, though, also for non-web. Mar 24 15:36:16 mazzoo, assuming there's no mistake on your pinmuxing, that is, you've actually implement what you say above then that's all you need Mar 24 15:36:37 mazzanet, this all assumes you've left CFG in the default direct connection mode rather than the optional shift out mode Mar 24 15:37:10 but the shift-out mode only changes the r30[0-1] behavior, in any case Mar 24 15:37:51 mazzoo, pastebin your dts with the pinmux you are using and somebody can take a look Mar 24 15:40:29 mazzoo: which pin is it? R30 bits 4 and 6 are both routed to GPIO pins which need to be put it high-Z mode for the PRU outputs to work Mar 24 15:42:00 mdp: bare metal, no linux, no dts. just registers Mar 24 15:42:40 show your pinmux register writes then Mar 24 15:42:44 alexanderhiam: pin V9 / GPIO1_31 / pr1_pru1_pru_r30_13 Mar 24 15:43:14 connector P8, pin 20 Mar 24 15:44:21 OMG it works Mar 24 15:44:47 mdp: thanks for asking to dump the register. my code still had the old 7 :P Mar 24 15:44:57 it's always pinmux! Mar 24 15:44:59 ;) Mar 24 15:45:13 * mdp nudges panto Mar 24 15:45:26 mdp: if not pinmux, it's toolchain Mar 24 15:45:32 +1 Mar 24 15:45:41 but first quadruple check pinmux Mar 24 15:45:46 nah, its always pebkac Mar 24 15:45:55 yes Mar 24 15:46:44 I'm adding that to my magic 8-ball Mar 24 15:46:57 case-sensitive filesystem Mar 24 15:47:00 permissions problem Mar 24 15:47:07 device isn't physically connected Mar 24 15:47:12 pinmux Mar 24 15:47:19 * panto hides Mar 24 15:47:20 endianness Mar 24 15:47:36 it's EVERY PROBLEM YOU'VE EVER HAD condensed into a paragraph Mar 24 15:47:48 missing ; Mar 24 15:48:12 ooh, good call. Wrong line-ending or terminator character. Mar 24 15:53:28 On the hardware side: Grounds not connected, floating pin, rising/falling edge, enable/chipselect line, dirty or bad connector, inadequate power decoupling... Mar 24 16:01:04 Any firmware 8-balls? Mar 24 16:04:15 -E_BEPCAK Mar 24 16:43:40 hi when i connect more than 11 devices to my beaglebone black it cant use them is this normal Mar 24 16:44:47 vi usb? Mar 24 16:44:52 yes Mar 24 16:45:22 dunno about usual, but not surprising Mar 24 16:45:35 whys that Mar 24 16:45:46 limited number of end points available Mar 24 16:45:50 usb is a weak link on the beagle line Mar 24 16:46:19 is there any device like a beagle that can handle more Mar 24 16:46:22 not sure how many devices can even be enumerated Mar 24 16:47:13 pauljbl: most low power processors are not designed to enable larger number of end points Mar 24 16:47:33 pauljbl: why do you need so many usb device end points? Mar 24 16:47:58 Isn't that just a question of software? Mar 24 16:48:05 for my bitcoin mining equipment Mar 24 16:49:15 it's a limitation of the USB OTG controller that has finite endpoints Mar 24 16:49:21 unlike an EHCI controller Mar 24 16:50:06 so there are no low power devices with a ehci controller Mar 24 16:50:15 I didn't say that Mar 24 16:50:20 I was referring to BBB/am335x Mar 24 16:50:33 do you know of any? Mar 24 16:50:39 you can get a BBxM that has a DM3730 w/ EHCI Mar 24 16:51:51 I flashed my BBB with debian and I notice that whenever I plug in an ethernet cable, the power LED starts flickering rapidly and the board becomes nonfunctional - is this a hardware problem or is it the OS? Mar 24 16:52:36 I'm also unable to boot up the board if the ethernet cable is already plugged in prior to booting up Mar 24 16:53:07 hmm... sounds like your board might not be getting enough power. How are you powering it? Mar 24 16:53:25 I'm using the 5V power supply Mar 24 16:53:45 PurpleDog: and what current rating? Mar 24 16:53:57 2A Mar 24 16:54:08 mdp: How's that setup? Why's there a need for it to have hardware resources (other than some buffering)? Mar 24 16:54:18 it was the suggested power supply from AdaFruit when I ordered the BBB Mar 24 16:55:18 pauljbl, by low power, I mean that part, in suspend, in a production system can have a total dissipation of ~2mW. Mar 24 16:55:31 for the whole system Mar 24 16:55:38 mdp: is there any where it says the number of endpoints Mar 24 16:56:14 PurpleDog: well that should be plenty Mar 24 16:56:31 pauljbl/ZiNC, the details on the musb are not in the TRM. the information is available separately from Mentor on how that OTG controller works Mar 24 16:56:52 that's what I thought tdreyer1, I have no idea what's going on - I even tried unplugging everything except for the SD card and the ethernet cable, but it still don't work Mar 24 16:56:59 mdp, you mean it works? Mar 24 16:57:20 I can try re-flashing the Angstrom image I guess Mar 24 16:57:53 mdp: I'm curious in general, not necessarily this specific one. Mar 24 16:58:01 actually I noticed a whole bunch of problems after trying to connect the ehthernet cable - it actually seemed to "brick" the BBB because it was completely unusable after that Mar 24 16:58:10 and when I tried to re-flash Debian, it failed the first time Mar 24 16:58:38 there are errata on scheduling various transactions back to back for different endpoints on the same controller hardware endpoints of all sorts..scheduling issues with waiting for nacks..blah blah blah. Mar 24 16:58:58 the end result is that there a finite limit on how many devices one can practically connect when it's operating in host mode Mar 24 16:59:26 So it's about the worst case conditions? Mar 24 17:00:27 ZiNC, it's best that you read drivers/musb/musb_core.c Mar 24 17:00:36 drivers/usb/musb/musb_core.c Mar 24 17:00:48 better get an exorcist while you're there too Mar 24 17:00:51 Okay. :) Mar 24 17:01:06 would a different distro make any difference? Mar 24 17:01:21 no, everybody uses the same driver Mar 24 17:02:19 so the bbxm could take alot more endpoints Mar 24 17:02:33 you have to use the EHCI port though Mar 24 17:02:42 xM exposes both the musb and EHCI Mar 24 17:03:12 the full-A connector on xM is the EHCI Mar 24 17:03:41 ok Mar 24 17:04:05 is that same as on a laptop Mar 24 17:04:34 the ehci Mar 24 17:06:41 pauljbl2, it's an ehci compliant...just has different errata than other ehci implementations Mar 24 17:09:05 is the musb a otg port Mar 24 17:15:00 is the musb a otg port Mar 24 17:20:45 pauljbl: you can run both ports in host or device mode, true OTG, I'd be very surprised if it would work. Mar 24 17:21:59 do you mean if it wouldnt work? Mar 24 17:22:46 true OTG is complicated, with dynamic host/slave negotiation and foo. Nobody does that. Mar 24 17:25:18 <_av500_> Nokia did it and see where they are now Mar 24 17:25:20 so you think i can connect lots of devices to the xM then? Mar 24 17:30:35 what is the proper way to power down the BBB after flashing the eMMC? Mar 24 17:30:37 if you use a usb hub, you can connect more than one at a time. Mar 24 17:30:51 PurpleDog: all leds solid? Mar 24 17:30:56 yup tbr Mar 24 17:31:17 PurpleDog: press reset or power cycle. system is idle and safe. Mar 24 17:31:27 thanks Mar 24 17:32:27 tbr: what about a cubieboard Mar 24 17:33:18 pauljbl: I have no knowledge of that platform. Mar 24 17:37:41 tbr: but with the ehci i should have a lot more end points Mar 24 17:39:53 pauljbl: I do not understand what you are getting at, at all. Mar 24 17:40:09 pauljbl: what is your use case? what are you trying to achieve? Mar 24 17:41:56 i want to connect about 20 usb devices all running at the same time on the beaglebone black i can only get 11 max running Mar 24 17:43:13 what sort of devices? Mar 24 17:45:20 they are used for bitcoin mining Mar 24 17:48:24 powered hub wattage? Mar 24 17:51:54 the hub has enough power i can get them all working in windows Mar 24 17:53:06 how much bandwidth does each of them consume on the bus? Mar 24 17:53:37 not sure Mar 24 17:53:49 pauljbl: in most cases, other methods of connectivity are a better option with you have that many devices Mar 24 17:54:29 Day 289, I had to hexedit my modules because someone broke the out-of-tree vermagic ... Mar 24 17:54:45 what methods would you suggest Mar 24 17:55:51 das: for what? Mar 24 17:56:22 pauljbl: i can't suggest any without know what you are doing.... hint "bitcoin mining" is not a valid answer Mar 24 18:00:39 pauljbl: I highly suspect you're running out of USB bandwidth Mar 24 18:04:04 what device would have more usb bandwidth Mar 24 19:13:56 is there a way to write the SD card images to the card so that it uses all free space instead of just the minimal amount? Mar 24 19:14:45 you mean so it writes zeroes to the balance of the card? Mar 24 19:15:21 I mean so that I can have a home folder of 32GB (size of my sd card) instead of only having 200MB of free space left after writing the image to the card Mar 24 19:16:02 oh, to expand the filesystem in the image on the card Mar 24 19:16:10 right Mar 24 19:16:37 terms like "partition" and "fdisk" and "resize" will be your googly friends Mar 24 19:17:39 that's what I figured, I guess I can just power off the BBB and use a disk utility to enlarge the partition Mar 24 19:21:36 PurpleDog: Yeah, that would be the best way to do it. YOu *can* grow an ext filesystem live, but it is risky. Better offline. Mar 24 19:23:12 alternately just add a new filesystem and move /home there? Mar 24 19:23:26 that might turn out to be more complicated Mar 24 19:23:49 yeah I think just expanding the root partition is easiest Mar 24 20:35:14 Hello Mar 24 20:35:42 Il y a des français? Mar 24 20:38:56 pas du tout. Mar 24 20:54:05 are folks successful compiling am335x-boneblack.dts with dtc from recent kernels? Mar 24 20:54:45 I keep getting "FATAL ERROR: Unable to parse input tree", but it's just the first #include, so it's difficult to debug Mar 24 21:03:51 privet! Mar 24 21:28:37 trying to install gqrx (software defined radio interface) that has ARM builds enables for saucy, raring, precise and quantal ubuntu - anyone got a clue which one would be best for Beagleboard XM Angstrom? or would it really matter Mar 24 21:29:53 the companion - gpredict buildt successfully a few days ago with no promises from the developer - so am optimistic Mar 24 21:46:44 \av500 how's things? Mar 24 21:54:22 Do the official Debian images have a realtime kernel? If not, how can I get a realtime kernel for my live audio application? Mar 24 21:58:17 jesselang, download kernel.org kernel, apply rt patchset and build Mar 24 22:02:02 joel_, I can probably get that far. Installing said kernel might the tricky part for me. Any place you can point me for that bit? Mar 24 22:08:42 will the rt patchset apply over the debian kernel source package trees? Mar 24 22:15:09 pjustice, that's a good question. Mar 24 22:15:37 try it and find out, keep a fire extinguisher handy! Mar 24 22:15:38 What about RT_GROUP_SCHED, is that in the official kernel? Mar 24 22:15:59 myself, doesn't sound promising. Mar 24 22:18:42 migh tneed to ask the rcn-ee dude .. he's good at that kinda thing Mar 24 22:20:33 joel_: ping Mar 24 22:24:09 hi! Mar 24 22:24:11 I'm very close to a usable solution without a realtime kernel. I think RT_GROUP_SCHED or PREEMPT_RT are what will help push it over the edge into the "very usable" area. Mar 24 22:25:11 I'm very close to a usable solution without a realtime kernel. I think RT_GROUP_SCHED or PREEMPT_RT are what will help push it over the edge into the "very usable" area. Mar 24 22:25:29 Oops. Sorry for the re-post. Mar 24 22:25:33 can someone confirm <10MB for hdparm -t with an USB hard drive Mar 24 22:51:33 I have installed the latest version of fusionpbx with freeswitch on the BBB. I'd like to post the image so others can use but don't know where Mar 24 23:42:55 is anyone running a mainline kernel? Mar 24 23:46:54 eewiki.net Mar 24 23:47:04 3.13 workin fine on mine Mar 24 23:48:30 those aren't quite mainlined, are they? Mar 24 23:48:57 I have been using a beaglebone for a while, and am interested in getting more involved with the open source side of things. Where is a good place to look for this? Mar 24 23:49:25 its git clone from kernel.org with patches by rob nelson aka rcn-ee Mar 24 23:50:11 neat set of scripts Mar 24 23:50:12 right, the patches ... Mar 24 23:50:18 i.e. not mainline Mar 24 23:50:33 though the 3.14 based ones have arely any patches Mar 24 23:50:52 you try to convince Linus Torvalds that Beagle patches are a priority ;) Mar 24 23:51:10 and not iMX or any other ARM chipset :) Mar 24 23:51:56 it's just not mainline if it's ... not in mainline. no judgement other than that :P Mar 24 23:52:23 I don't think therre EVERwill be .. Mar 24 23:52:30 but its as close as you'll get Mar 24 23:52:42 so its a loose definition at best :p Mar 24 23:52:59 its better than the 2.6 kernel previoulsy popular on ARM systems Mar 24 23:53:22 like i said, 3.14 looks to require almost no patches, i wouldn't be surprised if 3.15 worked mainline Mar 24 23:53:43 I've always wondered, when we run apt-get update/upgrade, does it also upgrade the kernel? Mar 24 23:53:44 who knows Mar 24 23:54:02 granito .. if it pulls in 'linux-image' or similar .. yes .. Mar 24 23:54:06 but not normally Mar 24 23:54:45 hmmm. I'm guessing rcn-ee images don't have that? Mar 24 23:55:11 kernel is build-yourself Mar 24 23:55:21 I don't think the debian repos have a kernel package even Mar 24 23:55:44 *those Mar 24 23:56:10 ok. I'm just wondering if it could be an attack vector if left unupgraded. I'm using owncloud and a BBB to replace my dropbox/calendar/contacts Mar 24 23:56:38 I assume you are running iptables or similar firewall on it? Mar 24 23:56:53 and you've removed the root account, etc all the usual security measures? Mar 24 23:56:56 working on it? :D Mar 24 23:57:02 yea root can't ssh in Mar 24 23:57:23 I have to setup a firewall Mar 24 23:58:02 I'm making a manual for all of this (http://www.gnube.hcoop.net/wiki) Mar 24 23:59:17 yeah, i'd like to get a proper kernel packaged up... likely in future updates for the bbb Mar 25 00:09:57 veremit, do you just load the kernel and dtb file, then do a 'bootm 0x80200000 - 0x80000000'? Mar 25 00:10:21 something like that, yea Mar 25 00:10:43 you point to the kernel image, point to the dtbs, point to the uEnv .. hit Go. Mar 25 00:11:51 I'm running the RobertCNelson / linux-dev script now, but when I did that with the mainline for my evmsk board it just froze at 'Starting Linux...' Mar 25 00:12:08 yeah .. you MUST do the UUID bit at the bottom :) Mar 25 00:13:03 and I gotta recommend keepin a serial debug cable, just in case :D Mar 25 00:13:17 what is that for? Mar 25 00:14:28 debugging :P esp when it don't boot and you got no console ! Mar 25 00:53:57 I have an image of Beagle Bone Black with Debian and fusionpbx I can post if anyone is interested and knows where it can be posted Mar 25 00:55:12 beagle forums? .. create a blog/wiki page Mar 25 00:59:22 thanks Mar 25 01:27:39 Any opinions on driving something like this: http://www.amazon.com/SainSmart-4-CH-4-Channel-Relay-Module/dp/B0057OC5O8 ?
