**** BEGIN LOGGING AT Sat Mar 23 02:59:59 2013 Mar 23 03:17:52 prpplague, I think I'm going to pull the trigger on the tick Mar 23 03:18:43 Russ: aww man Mar 23 03:18:44 so in the cape eeprom, if you set a pin to bidirectional, will it be set as input or output? Mar 23 03:18:52 Russ: you are going to call it the Tick? Mar 23 03:18:52 prpplague, why's that? Mar 23 03:19:09 it goes on a beagle's back, doesn't it? Mar 23 03:19:20 even though it's bidirectional, i'd like to know what voltage will be on it after the board comes up. Mar 23 03:19:30 Russ: i tried to sell the name for mranostay 's board as Tick, jkridner and gerald hated it Mar 23 03:19:42 Russ: i have a good logo for it Mar 23 03:20:46 * prpplague points to mranostay and complains Mar 23 03:21:12 Russ: mranostay seems to think he has to do _some_ work for his day job Mar 23 03:21:42 what's wrong with this logo? http://i.imgur.com/GWoIo2D.png Mar 23 03:21:46 Russ: instead of messaging me and says "what is thy bidding, my master?" Mar 23 03:22:02 Russ: hehe Mar 23 03:22:36 Russ: http://bp0.blogger.com/_xdBjq8Zu2QQ/RktxZYQqU2I/AAAAAAAAAPw/F-fdV19iarQ/s400/mutant+dog.jpg Mar 23 03:22:58 heh Mar 23 03:23:52 Russ: ewww, it has some "dead beagles" on the images google pulled up Mar 23 03:24:28 prpplague: 12V beagles? Mar 23 03:24:48 *cough* Mar 23 03:24:54 more like 220AV beagles Mar 23 03:25:01 s/av/ac Mar 23 03:27:15 mru: BeagleBone is not compatible with 12V power supplies - http://www.uer.ca/locations/galpics/norm/75018.jpg Mar 23 03:27:16 prpplague, I would have guessed your link was going to lead here http://i.imgur.com/yoSkSfK.jpeg Mar 23 03:27:29 Russ: hehe Mar 23 03:27:38 prpplague, but what if I'm powering *two* beagles, then I need a 12V power supply, right? Mar 23 03:28:03 Russ: hehe Mar 23 03:28:12 I have protection: http://hardwarebug.org/files/beagle_overvoltage.jpg Mar 23 03:28:34 which is what a software engineer on a project I was on actually believed Mar 23 03:28:49 after a couple pieces of destroyed prototype military hardware, they put in fixed supplies Mar 23 03:29:28 Russ: no shite? Mar 23 03:29:44 no shite Mar 23 03:30:02 software developers and hardware Mar 23 03:30:19 hehe Mar 23 03:30:28 hmmm Mar 23 03:30:54 * mranostay enters beer mode Mar 23 03:31:31 Russ: better yet, what i have been dealing with for three weeks now... a narcissistic software developer who thinks his CS degree is just as good as any EE Mar 23 03:31:43 heh Mar 23 03:32:01 prpplague: what i love is the CS people that take no circuits classes :) Mar 23 03:32:03 I'll talk to koen, don't worry Mar 23 03:32:21 Russ: hehe Mar 23 03:32:54 what did koen study? EE or CS Mar 23 03:33:06 mranostay: iirc he was EE Mar 23 03:33:12 * mranostay assemblies the dropout section of the channel Mar 23 03:33:34 yes, EE Mar 23 03:33:53 * prpplague hands mranostay the didgeridoo to summon the clan meeting Mar 23 03:34:14 EE ftw Mar 23 03:34:29 and silly mru was like one semester away :P Mar 23 03:34:45 one _FUCKING THESIS_ away Mar 23 03:34:46 mranostay: and so was i Mar 23 03:34:55 * mranostay facepalms Mar 23 03:34:56 * prpplague ran out of money Mar 23 03:34:57 waste of precious time Mar 23 03:35:03 ;oi Mar 23 03:35:10 oops Mar 23 03:35:34 prpplague: do 100k of student like all the cool kids Mar 23 03:35:47 mranostay: hell no Mar 23 03:35:56 mranostay: my father would have killed me Mar 23 03:36:04 i love the people i know that have 80-100k of debt in a shitty BA in Dance/blah/blah Mar 23 03:36:08 why spend time on something where form obviously is all that matters, content being mostly irrelevant? Mar 23 03:36:15 when you have a nice job offer Mar 23 03:36:15 mru, me too, finishing my thesis still Mar 23 03:36:30 but in CS Mar 23 03:36:35 Russ: wait you have a EE right? Mar 23 03:36:38 oh, and I have no debt Mar 23 03:36:39 mranostay: funny thing, my father put over 50 people through college Mar 23 03:36:39 CSE Mar 23 03:37:01 mranostay: but not one of them were his children, hehe Mar 23 03:37:07 prpplague: er story? Mar 23 03:38:33 mranostay: he was old school, didn't want his children to get an "easy ride" for school/work Mar 23 03:38:48 mru: i never said college generally isn't a waste of time.. like the first two years are bullshit classes Mar 23 03:39:26 oh, the 4 years I studied were definitely time well spent Mar 23 03:40:02 mru: hehe just not in most of the classes? Mar 23 03:40:25 oh, right, I wanted to find out from oshpark if I could put a breakaway on the pcb Mar 23 03:40:34 prpplague: i love the whole line "well we just want to see if you can stick it out for 4 years" :) Mar 23 03:40:36 many of the classes were useful, actually Mar 23 03:40:46 HR people i know have said this.. Mar 23 03:40:48 * prpplague learned more in 6 months in the army signal core, than three years of college Mar 23 03:41:04 that I can believe Mar 23 03:41:06 Russ: and? Mar 23 03:41:13 prpplague, waiting Mar 23 03:41:16 prpplague: i suppose 7+ years of working in a row in tech isn't enough to show i can stick with something :) Mar 23 03:41:30 mranostay: i have a good one for you Mar 23 03:41:34 * prpplague checks his email Mar 23 03:41:39 mranostay: of course not Mar 23 03:41:53 my undergrad CSE program was actually really good, I think less that half of the students actually stuck it out and graduated with it Mar 23 03:41:54 5 of those were with the same company effectively Mar 23 03:42:05 so of course, with such low rates of success, after I graduated, they gutted it Mar 23 03:42:09 mranostay: sticking with something _pointless_ is what they care about Mar 23 03:42:17 +1 Mar 23 03:42:44 if it was paid work, it doesn't count Mar 23 03:43:22 mranostay: "They're seeking an EMBEDDED Engineer who's experienced with 8- 16- 32- bit programming." Mar 23 03:43:33 :-/ Mar 23 03:43:42 mranostay: wait for it Mar 23 03:43:43 * mranostay facepalms Mar 23 03:44:03 mranostay: "- Work with the best! As a result they hire only the best; academics are important so you must have GPA above a 3.0!" Mar 23 03:44:26 heh Mar 23 03:44:31 hey, the head hunter found a canidate that has programmed basic on an 8 bit, 16 bit, and 32 bit computer Mar 23 03:44:46 prpplague: techically my ending GPA was 2.99.. not kidding :) Mar 23 03:44:54 * mru has never programmed basic on a 32-bit computer Mar 23 03:45:02 round it you #@$@#$holes :) Mar 23 03:45:16 * mru rounds it to 2 Mar 23 03:45:34 not floor() Mar 23 03:45:42 cellar() Mar 23 03:47:11 * prpplague decides to wander off in search of more beer and some sort of media viewing experience that does not involve words suchs as "factor, real, housewives, and/or dancing" Mar 23 03:47:49 for the cape eeprom, if i set a pin to output after boot, how to i control if it's high or low? Mar 23 03:48:19 or is it just random? Mar 23 03:48:36 * mru does not need more beer tonight Mar 23 03:48:37 PRU_EVTOUT2: depends on how long the pin is off it's meds and if it is extremely bi-polar or manic Mar 23 03:49:20 i'm guessing there's no control of the actual pin state on bootup, unless you roll your own kernel...cause why would that be included in the bootup pin config!?!? LOL! Mar 23 03:51:37 mru: lies! Mar 23 03:52:07 mranostay: you weren't here Mar 23 03:54:08 bear in mind it's soon 4am here Mar 23 03:54:15 heh Mar 23 03:54:30 sips Sam Adams Mar 23 03:55:01 and for some reason, it seemed like a good idea to pop down to the nightclub across the street a while ago Mar 23 03:55:14 hadn't been there for ages Mar 23 03:55:19 still as shitty as ever Mar 23 03:55:34 usually are Mar 23 03:55:38 the one with free entry, that is Mar 23 03:56:01 i hate nightclubs but seems if you want female to male ratio that isn't under 1 you have to Mar 23 03:56:07 nevertheless, if you enter with the right attitude, it can be entertaining Mar 23 03:56:40 i find slight apathy attitude works for me Mar 23 03:57:32 locate groups of 4-5 girls, watch from a safe distance how guy after guy tries his luck and fails Mar 23 03:57:38 sure would be nice if some of these reserved bits in the eerpom pin settings could be used to set the state of the output. Mar 23 03:57:56 i guess i'll go code digging. Mar 23 03:59:30 mrpacket_: nice connection there Mar 23 04:00:03 what? Mar 23 04:00:07 mru: yeah you have to have parity or n - 1 at worst to have a chance Mar 23 04:00:09 its not me, its you Mar 23 04:00:30 oh that line Mar 23 04:00:43 mranostay: groups of girls are always no-go Mar 23 04:01:07 i did a demonstration of laser cut stencils Mar 23 04:01:09 roar! Mar 23 04:01:10 mru: but how often do you see a girl alone at a bar? Mar 23 04:01:14 to the DIY christmas crowd Mar 23 04:01:14 never Mar 23 04:01:18 ^ Mar 23 04:01:18 exactly Mar 23 04:01:22 mixed groups with a surplus of girls are a different matter Mar 23 04:01:34 or a pair of girls Mar 23 04:01:40 giggity? Mar 23 04:01:50 i have a wife. thats enough woman for me Mar 23 04:01:52 3 or more on their own are usually a waste of time Mar 23 04:02:10 mmmm...laser cut stencils Mar 23 04:02:25 in mylar Mar 23 04:02:35 girls in mylar... Mar 23 04:02:40 steel, must have steel Mar 23 04:02:48 balls of? Mar 23 04:02:56 stencils of Mar 23 04:06:32 https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-prn1/601581_10151517050132661_1165791286_n.jpg Mar 23 04:08:21 stencil ya ya, but what's that stuff in the background?

Mar 23 04:11:22 heh, http://www.dimasmt.nl/cmpage/showphoto.asp?file=dotsize.jpg Mar 23 04:11:27 nice font spacing Mar 23 04:11:57 Russ: trying to piss off mru? :) Mar 23 04:12:02 basically Mar 23 04:12:02 mrpacket_: Not bad. What'd that run you? Mar 23 04:12:11 I bought it 2nd hand on ebay Mar 23 04:12:18 cost me USD$1800 Mar 23 04:12:25 they are $9k new Mar 23 04:12:38 Russ: :) Mar 23 04:12:43 nice Mar 23 04:12:47 its been a godsend Mar 23 04:13:15 so EIA0201? Mar 23 04:14:04 I like the rotation, that's nifty Mar 23 04:14:33 i have not tryed 201 Mar 23 04:14:35 mranostay: nice Mar 23 04:14:36 but you probalby could Mar 23 04:14:57 mrpacket_, 0402 isn't too bad with a vacuum pen Mar 23 04:15:07 i put 0402 down with this no problem Mar 23 04:15:24 i hav'nt had any call ( yet) to use 0201 Mar 23 04:15:49 mrpacket_, it does seem to offer some organization wins over my whiteboard method Mar 23 04:15:50 mranostay: paper on what? how to fail at girls? Mar 23 04:15:52 http://www.flickr.com/photos/russdill/8542960490/ Mar 23 04:15:54 I think that's been done already Mar 23 04:16:12 i use a bit of sofware http://alciom.com/fr/telechargements/ressources-gratuites.html Mar 23 04:16:24 that provides you layout data Mar 23 04:16:27 its pretty cool. Mar 23 04:16:47 Logiciel SMTassisteant Mar 23 04:16:49 its free Mar 23 04:16:57 I have a python app that does that for me Mar 23 04:17:04 web page in French, but instrucitons are in English Mar 23 04:17:20 does your python app, give you a graphic? Mar 23 04:17:23 to follow Mar 23 04:17:25 yes Mar 23 04:17:35 oh nice. Mar 23 04:17:40 and it wont' be in winblow Mar 23 04:17:42 ? Mar 23 04:17:49 any os you want Mar 23 04:18:02 http://www.flickr.com/photos/russdill/8395379215/ Mar 23 04:18:05 beaglebone-black on Mar 23 04:18:11 onboard Mar 23 04:18:12 :-) Mar 23 04:18:13 my dima Mar 23 04:18:34 ok!!! thats cool Mar 23 04:18:35 :-) Mar 23 04:18:42 Russ, is the soruce avaialbe? Mar 23 04:18:47 it probably has a bug or two, and could use some new features, like highlighting all matching components Mar 23 04:19:18 id put a beaglebone dedicated on the dima Mar 23 04:19:23 with a monitor Mar 23 04:19:27 just to run this Mar 23 04:19:28 :-0) Mar 23 04:20:06 do you give it the PNP data? Mar 23 04:20:16 one sec Mar 23 04:22:18 https://github.com/russdill/pnp Mar 23 04:22:43 it currently works with geda pcb, but it uses text files, it takes a bom, an xy file, and board images Mar 23 04:23:44 just one file? Mar 23 04:23:46 wow Mar 23 04:23:56 418 lines Mar 23 04:24:12 mmm...steel http://i.imgur.com/eMAABhR.jpg Mar 23 04:24:14 i had wondered if i could spin the bins automatically Mar 23 04:24:36 steel is good Mar 23 04:24:42 but $350/stencil Mar 23 04:24:47 for protoptypes Mar 23 04:24:53 and wait 3 days Mar 23 04:24:58 the pnp.py tool lets you crudely choose some sort order, and it will print out an ordered component list, so you can fill you bins in that order Mar 23 04:25:05 $350!?!? Mar 23 04:25:14 mylar = $2.50/m2 Mar 23 04:25:20 both advanced circuits and seeed are much less Mar 23 04:25:21 laser time = $1/min Mar 23 04:25:33 yeah, thats for small stencils Mar 23 04:25:37 http://www.4pcb.com/smtstencils/index.html Mar 23 04:25:38 $350 is a full framed one Mar 23 04:25:50 I got a full 8.5x11 stencil from advanced circuits Mar 23 04:25:56 $99 Mar 23 04:26:05 i'll give you that the steel ones are better than the mylar Mar 23 04:26:11 russ, what are you making? Mar 23 04:26:12 hmm...not quite 8.5x11, lets see Mar 23 04:26:25 was that framed? Mar 23 04:26:30 8x10 Mar 23 04:26:38 or was it one of their prototype ones with the fold up edges? Mar 23 04:26:41 PRU_EVTOUT2, quite a few things, can you be more specific? Mar 23 04:26:51 the actual board was 7x3, but the steel sheet was 8x10 Mar 23 04:27:02 just flat steel Mar 23 04:27:07 right.. Mar 23 04:27:15 what' the big red board? Mar 23 04:27:31 ah that one, that's me trying to finish my thesis Mar 23 04:27:38 fits into some slot, pci-e maybe? Mar 23 04:27:39 we are in the process of trying to get 3 hour turn around from Design to completed PCB Mar 23 04:27:55 parts loaded Mar 23 04:27:55 and back on engineers desk Mar 23 04:27:55 so, it's a thesis generator? Mar 23 04:28:06 PRU_EVTOUT2, here, this one has a description http://www.flickr.com/photos/russdill/8542591023/ Mar 23 04:28:19 mrpacket_, crazy Mar 23 04:28:45 why is that crazy Mar 23 04:28:55 mrpacket_, 3 hours is really short Mar 23 04:28:57 are you milling? Mar 23 04:29:03 we were Mar 23 04:29:07 isolation milling is crap Mar 23 04:29:15 *don't* do it Mar 23 04:29:17 ohh, that's pretty cool! Mar 23 04:29:23 what's your new plan? Mar 23 04:29:58 Direct Laser Imaging Mar 23 04:30:00 russ, what's been the most difficult part so far? Mar 23 04:30:29 PRU_EVTOUT2, I'm still doing bringup, I can configure the fpga and all that, currently I'm trying to talk to the ddr2 Mar 23 04:30:32 And other bit of advice, about rapid protyping. Mar 23 04:30:35 Avoid LPKF Mar 23 04:30:38 they are shockers Mar 23 04:30:40 once I figure out what all is working and what isn't, then I'll know :) Mar 23 04:31:09 so, your description mentions an arm processor is usually used? Mar 23 04:31:09 mrpacket_, so you start with copper clad and ablate it with laser? Mar 23 04:31:16 no.. Mar 23 04:31:25 http://www.bungard.de/index.php?option=com_content&view=article&id=144&Itemid=28&lang=english Mar 23 04:31:30 PRU_EVTOUT2, to interface to flash memory, yes Mar 23 04:31:40 mrpacket_, didn't know how direct you meant Mar 23 04:31:56 board is covered in photoresist Mar 23 04:32:02 UV laser exposes it direclty Mar 23 04:32:07 no immediated art-work Mar 23 04:32:21 how long/ Mar 23 04:32:24 ? Mar 23 04:32:26 how long to? Mar 23 04:32:37 russ, what's the benefit of an fpga over arm? Mar 23 04:32:40 draw out a pcb, like 3x3? Mar 23 04:32:56 A Double sided Eurocard PCB, is 12 minutes Mar 23 04:33:07 PRU_EVTOUT2, its hard to find an ARM available in small quantities that can talk to 10 flash channels at the same time Mar 23 04:33:16 mrpacket_, much faster than i'd expect Mar 23 04:33:20 yes. Mar 23 04:33:26 Isolation milling would be several hours Mar 23 04:33:29 I'm guessing no mask? Mar 23 04:33:33 and the results are crap Mar 23 04:33:40 solder mask is no problem Mar 23 04:33:51 so you do print one? Mar 23 04:33:57 same process Mar 23 04:33:57 lpi? Mar 23 04:34:02 once the board is finish Mar 23 04:34:09 cover it in mask Mar 23 04:34:12 expose it Mar 23 04:34:17 and develop it Mar 23 04:34:29 every process is exactly like a 'normal' pcb Mar 23 04:34:35 do you do pth? Mar 23 04:34:51 not now Mar 23 04:34:52 but i will be Mar 23 04:35:00 so its just 2 layer right now Mar 23 04:35:06 itsyes. Mar 23 04:35:11 but we are considering the multilayer Mar 23 04:35:22 its about 80,000 Euro Mar 23 04:35:26 for the whole lab Mar 23 04:35:26 is this for analog stuff then? Mar 23 04:35:52 no, mostly its all digital Mar 23 04:36:01 lots of control system stuff Mar 23 04:36:54 I'm heading up to Germay in June Mar 23 04:36:59 and will ahve a play Mar 23 04:37:02 and look Mar 23 04:37:25 unlike the rest of the world, we simply don't have the option of overnight PCB services Mar 23 04:37:40 because we dont' have an electronics industry to sepak of Mar 23 04:37:46 but i'm keen to change that Mar 23 04:37:52 big jump between 24hr turn and 3hr turn though Mar 23 04:37:58 yup. Mar 23 04:38:03 but its doable Mar 23 04:38:31 being able to have such fast turn, means that engineers dont' ahve to project swap Mar 23 04:38:45 that is a *massive* productivity increase Mar 23 04:39:28 I spend a lot more than 3 hours reviewing designs Mar 23 04:39:57 course, it takes 2 weeks for a 2 layer to come back from oshpark Mar 23 04:51:56 thyes. Mar 23 04:51:58 yes. Mar 23 05:25:02 Can the BeagleBoard xM recharge the RTC battery and, if so, what do I have to do to enable recharging? Mar 23 05:35:38 Dammit. Why are all the ICs that are perfect for what I want either obsolete or not recommended for new designs? Mar 23 05:35:42 grr Mar 23 05:56:03 better hit the bar for a brew Mar 23 06:00:59 sounds like a great idea Mar 23 06:01:11 What sounds good?

Mar 23 10:23:53 er wrong upscroll Mar 23 10:41:53 Has anyone been successful to run opencv on beaglebone? Mar 23 10:44:44 I haven't been able to get pass through a basic call of cvCaptureFromCAM for beaglebone 3.1 MP camera cape Mar 23 10:45:31 The call cvCaptureFromCAM fails at VIDIOC_REQBUF:Cannot allocate memory Mar 23 10:48:08 sounds like a pretty clear error description Mar 23 10:48:47 is it happening because of less memory on beaglebone Mar 23 10:48:58 or some bug in driver? Mar 23 10:49:31 I can get my USB camera working but cape camera doesn't work at all Mar 23 10:50:02 how should we know what consumes the memory on your system or how much memory you are trying to allocate? Mar 23 10:50:39 <_av500_> LinuxOmicron: try a simple v4l2 capture example and make that work first Mar 23 10:50:42 <_av500_> then move to opencv Mar 23 10:51:44 Yes. I did that. Found a source from here. http://moinejf.free.fr/svv.c Mar 23 10:52:00 I tried it. This code works fine most of the time. Mar 23 10:52:52 Noticed that the req.count is 4 in svv.c and in opencv source code also Mar 23 10:55:42 I have posted dmesg output on https://groups.google.com/forum/?fromgroups=#!topic/beagleboard/Yi1FJEr1R1Q Mar 23 10:56:18 you could use strace to see the error. or even gdb Mar 23 10:57:14 that would give you a hint about how much memory you are missing, if that error message is true Mar 23 10:58:06 ok.. I will try strace Mar 23 11:00:18 I created swap partition too but didn't work with swap too Mar 23 11:00:41 real memory is likely needed Mar 23 11:00:51 mru: did you know that there is a mosquito native to the london underground?

Mar 23 16:28:15 I am using csr based usb bluetooth device Mar 23 16:28:16 subash fine Mar 23 16:29:14 i am trying to receive file from my pc to the bbxm and can't do it and the other way transfer is not possible Mar 23 16:29:48 ? Mar 23 16:29:58 connect it via ethernet Mar 23 16:30:01 or usb Mar 23 16:30:34 i am able to pair with my pc and send a file from bbxm to the pc Mar 23 16:31:10 but when i try to send a file from the pc i cannot find the bbxm's bluetooth name listed in my pc Mar 23 16:31:23 is there any configuration or package that i need to install in my bbxm? Mar 23 16:34:20 i have marked the visible checkbox also but still it doesn't show up in my pc. Mar 23 16:35:20 is there any additional package available from angstrom that can make the bbxm receive files over bluetooth? Mar 23 16:37:16 again why tinker with bluetooth connect is via usb Mar 23 16:39:44 woglinde: my requirement is to validate basic file transfer from command line but the rfcomm connection times out. so i tried the gnome based solution. but again this seems to only send from bbxm but not receive. Mar 23 16:40:53 again usb to connect and you do not have to hassle with bluetooth Mar 23 16:41:59 woglinde: i could transfer the files via ethernet but my requirement is to use bluetooth. i want to setup this bbxm to receive files via bluetooth from mobile phones. Mar 23 16:43:52 \o/ Mar 23 16:44:06 linux-meta (3.8.0.14.28) raring; urgency=low Mar 23 16:44:06 * linux ABI 3.8.0-14 Mar 23 16:44:06 * Rename omap to generic. Leave omap in place as transitional Mar 23 16:44:06 packages. Mar 23 16:44:10 finally ... Mar 23 16:44:35 ubuntu has a multiplatform arm kernel now ... with BBXM support Mar 23 16:45:55 subash than google on obex on linux and what to setup Mar 23 16:46:39 I remember playing with some obex thing on linux once Mar 23 16:46:42 woglinde: is obex the package needed for receiving files over bluetooth? Mar 23 16:47:01 when I found that it would happily read or write any file in the filesystem it had permission for, I promptly deleted it Mar 23 16:47:16 that was years ago though Mar 23 16:47:21 maybe it's been fixed Mar 23 16:48:01 mru: could you please point me to the package or source that i can compile? Mar 23 16:48:33 I have no idea what would be suitable today Mar 23 16:58:30 subash you can soemthing find out on yourself? Mar 23 16:58:42 package manager under angstroem is opkg Mar 23 16:58:50 maybe google is down Mar 23 16:58:57 must be Mar 23 16:58:59 for obex are hundreds tutorials out there Mar 23 17:00:41 I have a beagleboard-xm (uname -a > Linux ubuntu 3.2.0-23-omap #36-Ubuntu Tue Apr 10 20:24:21 UTC 2012 armv7l armv7l armv7l GNU/Linux) that runs prebuilt ubuntu-server image. I don't have the spidev under /dev directory by default. what module do I need to load to get spidev? here are the existing modules http://pastebin.com/wtNxbkRU Mar 23 17:03:20 with 3.2, you need to recompile the kernel. I believe the eLinux.org wiki has documentation. Mar 23 17:03:46 well, at least I don't think you can just 'modprobe' it. Mar 23 17:04:10 angs: check out eLinux.org. Mar 23 17:04:22 jkridner, thank you I will do that Mar 23 17:15:25 angs: looks like with a kernel command-line argument (buddy=) you can actually turn on spidev: https://github.com/beagleboard/kernel/blob/beagleboard-3.2/patches/beagle/0019-Enable-buddy-spidev.patch Mar 23 17:15:49 not sure if that landed mainline. Mar 23 17:17:32 hmmm... looks like none of the buddy stuff is in http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/mach-omap2/board-omap3beagle.c Mar 23 17:18:17 new way would be all with devicetree, so I'd doubt the mainline would accept the patch now. :( Mar 23 17:18:42 so much stuff out-of-tree. :( Mar 23 17:18:54 well, at least it is on http://github.com/beagleboard/kernel Mar 23 17:19:04 so, your distro probably has it. Mar 23 17:19:19 angs: do you understand how to set 'buddy=spidev'? Mar 23 17:23:05 morning Mar 23 17:23:12 troll Mar 23 17:33:58 gm mranostay, mru Mar 23 17:34:44 I wonder if there's any chance someone will have time to show http://elinux.org/BeagleBoard/GSoC/Ideas some love. Mar 23 17:50:51 jkridner, thank you for your help! sorry that I could not understand how I need to set it. how can I do that? Mar 23 17:51:23 depending on your u-boot version, through either boot.scr or uenv.txt... Mar 23 17:51:44 if you have uenv.txt, you can simply add a line that says 'buddy=spidev', I believe... Mar 23 17:52:00 best to check your bootcmd to make sure it reads in the value of 'buddy' Mar 23 17:52:33 if not, it typically reads in some kind of optional arguments (optargs) and you can add something like (optargs="buddy=spidev") Mar 23 17:58:06 jkridner, here is my boot.script http://pastebin.com/bSq5W5nS does it matter where I add buddy=spidev on that file? Mar 23 17:58:16 morning jkridner Mar 23 17:58:43 angs: you'll need to add it to your bootargs line. Mar 23 17:59:05 is boot.script compiled into a boot.scr on your board? Mar 23 17:59:26 boot.scr? how old is this u-boot? Mar 23 17:59:26 I say compiled, I mean run through u-boot mkimage Mar 23 18:00:00 which ubuntu image are you using angs? Mar 23 18:00:49 mranostay: not everyone is the bleeding edge kernel wrangler you are! some of us are even happy spending more time in JavaScript. ;-) Mar 23 18:00:51 jkridner, I am using this image https://wiki.ubuntu.com/ARM/OMAP#Precise_Pangolin_.2812.04.29-1 Mar 23 18:01:32 do you have a boot log? just curious about the u-boot version, mainly. Mar 23 18:02:02 not sure where you found the 'boot.script', but you need to make sure your u-boot actually reads it and it isn't a source file. Mar 23 18:02:16 where can I dinf that log file? Mar 23 18:02:18 you want to have 'buddy=spidev' within your bootargs Mar 23 18:02:35 typically you'd make it by booting the board connected to a serial port. Mar 23 18:02:48 capture the serial port and viola Mar 23 18:03:32 typing 'dmesg' in the terminal will give you most of the output, but none of the bootloader stuff before the kernel starts. Mar 23 18:03:54 U-Boot 2011.12 (Apr 02 2012 - 18:10:22) I captured some data when I reboot it http://pastebin.com/5V4QHPxP Mar 23 18:04:58 angs: yup, that's pretty old. you probably need to run boot.script through mkimage to make boot.scr. Mar 23 18:05:21 Note that rcn-ee's Ubuntu images at http://elinux.org/BeagleBoardUbuntu#Demo_Image are typically better supported by the #beagle community. Mar 23 18:05:33 GSoC? isn't that too late? Mar 23 18:05:40 hmmm... preenv.txt eh? Mar 23 18:05:42 I will load rcn-ee's image Mar 23 18:05:56 ds2: they are taking applications until for several days still. Mar 23 18:05:58 thank you very much for your help jkridner Mar 23 18:06:11 Oh... thought jessica's message said friday? Mar 23 18:06:19 (yesterday) Mar 23 18:06:32 looks like you could probably just drop a preEnv.txt onto your FAT partition with some environment variables.... Mar 23 18:07:05 not sure what is picked up by their u-boot. would be best if you stopped it during boot and typed 'printenv' to get a look at what bootcmd is set to... Mar 23 18:07:26 ds2: that was the internal deadline she was trying to push to make sure we could get the application in on time. Mar 23 18:07:41 do people not realize all these hacks put in place are getting about as complex as doing it the normal way w/proper flash and such? Mar 23 18:07:45 she put it back on me to update the ideas page... which is the hard work IMO. :( Mar 23 18:07:55 jkridner: oh :( Mar 23 18:08:12 ds2: yeah... they are getting rather complex because they aren't consistent. Mar 23 18:08:28 I'm concerned 'saveenv' isn't being built into next-gen Bone. :( Mar 23 18:09:07 not sure why we shouldn't be able to support it. I'd want it ignored if booting off of uSD card, but it should be respected when booting off of eMMC! :-/ Mar 23 18:09:22 ds2: patches welcome! Mar 23 18:09:32 saveenv isn't being built cuz emmc is not natively supported Mar 23 18:09:38 (or mmc for that matter) Mar 23 18:09:59 jkridner: what about adopting the fastboot stuff? Mar 23 18:10:35 it isn't ideal but it will give you some of what you want Mar 23 18:10:44 ds2: even on the flat boot partitions? Mar 23 18:10:54 I don't know about the fastboot stuff. Mar 23 18:11:00 jkridner: yep. used it with nonandroid stuff on another chip Mar 23 18:11:22 basically you build boot.img's (zImages, wrapped with a potential initrd + commandline) Mar 23 18:11:33 that way you can customize the commandline on a presistant basis Mar 23 18:11:55 is FIT useful in the same regards? Mar 23 18:12:07 FIT? not familiar with that Mar 23 18:12:15 I'd love something that made a ramdisk easier to use. Mar 23 18:13:04 fastboot gets you there part of the way Mar 23 18:13:11 FIT is just uImage+devicetree where you can throw arbitrary objects into the devicetree (including uImages). joel_ has been pushing it and it is used on chromebooks Mar 23 18:13:24 and the rowboat folks seems to have done some of the work to get it into u-boot Mar 23 18:13:29 ds2: you can look up Joel's presentation at ELC. Mar 23 18:13:32 oh.. .this is different Mar 23 18:13:46 k. Mar 23 18:14:06 boot.img is what most android devices use Mar 23 18:14:35 you can patch in the fastboot support onto stock u-boot for a transition Mar 23 18:14:47 and did I mention, it works w/o a serial console? :D Mar 23 18:19:27 what do you mean 'works w/o a serial console?'? Mar 23 18:19:44 I don't see why not to enable fastboot, especially if it is just an 'extra'. Mar 23 18:19:44 all the fastboot stuff happens over USB Mar 23 18:19:55 not sure how it impacts the rest of the experience... Mar 23 18:20:00 including dfu support. Mar 23 18:20:01 it might upset the DFU folks Mar 23 18:20:06 how do you stop the boot over USB? Mar 23 18:20:17 ah. :( Mar 23 18:20:21 it waits for a handshake over USB, IIRC Mar 23 18:20:28 any chance you could still switch-over to DFU? Mar 23 18:20:31 fastboot does most of what the DFU stuff does Mar 23 18:20:48 so, would you have your host waiting on the device? Mar 23 18:20:51 not automatically Mar 23 18:20:53 yep Mar 23 18:20:54 don't want to slow the boot down. Mar 23 18:21:12 this isn't that different then how NOLO did things Mar 23 18:21:18 could we switch to DFU without a binary replacement? Mar 23 18:21:30 it would be fine if we could switch using a run-time config. Mar 23 18:24:05 you could put in a env.txt to do that Mar 23 18:45:43 jkridner: is a node.js kernel in the works? Mar 23 18:46:00 is it not a kernel? Mar 23 18:46:26 snow and maintenance in Denver .... Mar 23 18:47:25 Crofton: stuck in the airport? Mar 23 18:47:56 yeah Mar 23 18:48:41 shit Mar 23 18:48:44 boarding I think Mar 23 18:51:07 that's what they want you to think... Mar 23 18:51:42 also, it's the gate closing time that counts in punctuality statistics Mar 23 18:52:19 so if they lock you on the plane while sitting on the ground for 3 hours, it still shows up as departed on time Mar 23 19:12:26 mru: you are kidding right? Mar 23 19:12:36 I wish I were Mar 23 19:13:51 of course it'll still arrive late Mar 23 19:17:15 mru: that one is a little harder to fake Mar 23 19:18:35 i got grumped at by the gate staff a few weeks ago Mar 23 19:18:45 i was in the lounge Mar 23 19:19:01 and went to the gate at the time that they told me to be there Mar 23 19:19:22 I never have time to visit the lounge Mar 23 19:19:23 they had started to board the plane early, in an attempt to leave early Mar 23 19:19:34 yeah, they'll do that sometimes Mar 23 19:19:44 and then some arse has to show up late and ruin it all Mar 23 19:19:46 because of adverse wind consiions Mar 23 19:20:09 hey, if they had just said. i would have been happy to get home 1/2 hour earlier. Mar 23 19:20:56 lounge wait times are useful sometimes. Mar 23 19:21:06 however it certainly is not somethign i would pay for. Mar 23 19:21:35 I usually get to the airport late enough that there's no point thinking about it Mar 23 19:22:12 arriving 60-90 minutes before departure is typically what I aim for Mar 23 19:22:37 a bit more if it's a shitty airport or one I don't know Mar 23 19:23:18 for the local airport I leave home an hour before departure Mar 23 19:25:22 Anyone able to assist me getting past the "40W" prompt. Doing the "user" button while booting with no luck Mar 23 19:26:13 wtf is a 40W prompt? Mar 23 19:26:51 when booting that is all that comes up on console Mar 23 19:27:04 I'm a newbie Mar 23 19:27:18 which board? Mar 23 19:27:35 not that it matters, 40W is good news Mar 23 19:27:45 all you need now is a properly prepared sd card Mar 23 19:28:54 which means it should have a FAT partition with an even number of blocks, marked active/bootable, and containing MLO etc Mar 23 19:28:59 mru: is like WD40? Mar 23 19:29:45 speaking of which, I noticed the other day the local grocery store keeps the WD40 next to the booze Mar 23 19:32:02 interesting placement Mar 23 19:39:44 ok, I'll try again but I followed the procedure in docs and still couldn't get it passed that prompt. Thanks for the response Mar 23 19:52:34 exact steps! Mar 23 20:02:26 ROM says *halp*, I can't find MLO Mar 23 20:03:55 Joe_____: advise you to capture the complete serial log and paste it using pastebin.com Mar 23 20:04:19 oh.... guess you have a formatting issue.... should have read. Mar 23 20:04:32 did you copy your card using dd with a .img file? Mar 23 20:04:57 Joe_____: anyway "procedure in docs" is far too ambiguous. Mar 23 20:06:35 http://code.google.com/p/beagleboard/wiki/BeagleboardRevC3Validation Mar 23 20:06:47 <_av500_> that wiki still exists? Mar 23 20:06:48 tried fat and fat32 Mar 23 20:07:10 Joe_____: go with instructions on eLinux.org if you can. Mar 23 20:07:11 copied mlo... Mar 23 20:07:19 ok Mar 23 20:07:26 http://beagleboard.org doesn't link to that old stuff anymore. Mar 23 20:10:21 maybe I'll just try to use a prebuilt image Mar 23 20:10:26 wget http://rcn-ee.net/deb/rootfs/quantal/ubuntu-12.10-console-armhf-2013-02-16.tar.xz Mar 23 20:11:10 just make sure you follow the steps given to build an SD card. Mar 23 20:11:35 that probably is pretty reasonable to use. Mar 23 20:12:20 <_av500_> its either fat partition not bootable or that odd/even partition size thing Mar 23 20:16:30 <_av500_> speaking of dongles: http://imgur.com/gallery/M0ZjW Mar 23 20:21:03 whoa _av500_ you trying to get us all fired? Mar 23 20:21:21 <_av500_> if I can Mar 23 20:21:37 one can but try Mar 23 20:21:42 <_av500_> let me tweet a picture of you Mar 23 20:26:13 sssh let's blame jkridner Mar 23 20:26:20 in public?
