**** BEGIN LOGGING AT Sun Apr 07 02:59:58 2013 Apr 07 03:13:52 So I just updated to kernel 3.6 on my beaglebone. Noticed that /sys/kernel/debug/omap_mux is not there anymore. Quick look online and it has been replaced. The new interface is called pinctrl. Can't seem to find any documentation on it for usage with the beaglebone. Does anyone know how to use it or where I can find a manual? Apr 07 03:23:27 there are docs man :) Apr 07 04:02:50 Documentation/pinctrl.txt Apr 07 05:05:50 heh. http://retailcomic.com/comics/april-7-2013/ Apr 07 06:15:22 <_av500_> gah Apr 07 06:49:33 hai Apr 07 07:02:50 Can I reset the beaglebone from the command line (over the fdti usb)? I am currently using CCS just for that purose Apr 07 07:03:25 <_av500_> linux? Apr 07 07:03:28 <_av500_> or minix? Apr 07 07:04:45 I am currently running Linux (on my development system), MINIX doesn't have usb ftdi support Apr 07 07:05:09 but I am porting MINIX 3 to the bone Apr 07 07:05:36 <_av500_> you could do something like: http://arduino.cc/forum/index.php?topic=152919.0 Apr 07 07:05:38 as it will allow us to have networking :P Apr 07 07:05:49 <_av500_> use RTS or DTS on the FTDI to reset the bone Apr 07 07:07:31 yes, I also (already have a similar setup) where I connect to the arduino over serial and enter "reset" but it'snot a portable setup Apr 07 07:07:50 <_av500_> ? Apr 07 07:08:20 I like the bone as it's just a one or two wire setup and I move from home/work a lot Apr 07 07:08:33 <_av500_> and one wire is not serial? Apr 07 07:09:15 <_av500_> well, since you are on bone white, you can also use openOCD to reset Apr 07 07:09:16 it's usb on the bone Apr 07 07:09:27 <_av500_> yes Apr 07 07:09:29 <_av500_> and? Apr 07 07:09:56 <_av500_> your laptoip has no usb? Apr 07 07:11:26 "and one wire is not serial?" -> no , it's usb. My laptop does has usb. I will try openocd. usually it fails badly Apr 07 07:12:12 BTW I did some of the initial work on getting openocd to support the TI hardware(getting the scan chain discovered) Apr 07 07:14:18 <_av500_> well yes, usb serial Apr 07 07:14:28 <_av500_> is what I meant Apr 07 07:17:06 <_av500_> ok, there is something hooked up to SYSWARMRESET on the bone Apr 07 07:17:08 <_av500_> from the FTDI Apr 07 07:17:32 <_av500_> so using FTDI on bitbang mode should get you to toggle that pin Apr 07 07:17:44 <_av500_> since DTS is not broguht out Apr 07 07:20:18 DTS all things! Apr 07 07:22:46 there is also S(ystem)RST on the jtag header Apr 07 07:23:14 hmm. I don't use that. Apr 07 07:24:17 that is optional Apr 07 07:24:42 <_av500_> arf, reset is on ACBUS0 Apr 07 07:24:52 <_av500_> which is not a bitbang gpio Apr 07 07:25:08 <_av500_> what is this MPSSE? Apr 07 07:25:23 Thanks I have enough to work on ! Apr 07 07:27:18 did someone say bitbang? Apr 07 07:27:28 inverse bit bang Apr 07 07:27:31 sucks Apr 07 07:27:38 cycles Apr 07 07:28:32 is that legal there? Apr 07 07:28:53 is it legal anywhere? Apr 07 07:31:10 heh Apr 07 07:31:34 mrpackethead: why not run it through it a inverting hex buffer? Apr 07 07:31:40 or the prop delay a problem? Apr 07 07:32:29 inverting hex buffer waht? Apr 07 07:33:41 mrpackethead: what you need that is a 'inverse' bit bang? Apr 07 07:34:15 the inverse of bit baning is receiving a data stream without a uart Apr 07 07:37:52 was pretty happy about the phone thing. Apr 07 07:38:00 i lost my phoen last night Apr 07 07:38:08 even with GPS tracking.. coud'tn find it Apr 07 07:38:41 out by the sheep barn? Apr 07 07:38:47 at the beach Apr 07 07:42:25 mranostay: are there any uarts on teh AM3559? or is it all vai the USB? Apr 07 07:44:55 there are Apr 07 07:45:07 TTL though Apr 07 07:47:35 yeah, that might be the way i need to do things Apr 07 07:47:53 if i can get a 250k clocking rate Apr 07 07:47:59 which might be problematic. Apr 07 07:58:45 * mranostay sleeps Apr 07 08:07:36 <_av500_> mranostay: plugged in? Apr 07 08:09:39 <_av500_> mrpackethead: 250k should be no problem Apr 07 08:10:33 _av500_: i see in the TRM, theres 4 or so.. Apr 07 08:10:36 uarts that is Apr 07 08:10:39 <_av500_> yes Apr 07 08:13:31 moin boys Apr 07 08:13:58 if the bone cannot do 250k, then i dont know what can Apr 07 08:14:14 i'm not worried abou it not reaching at least 250k Apr 07 08:14:22 i'm worrieda bout how close to 250k it will get Apr 07 08:14:33 1% Apr 07 08:14:47 prolly even better with the high clockrate of the bone Apr 07 08:16:13 its hard to remember the entire 4593 pages of the SPRUH73 Apr 07 08:16:28 <_av500_> mrpackethead: I don 1mbit uart on the omap3 Apr 07 08:16:39 <_av500_> do* Apr 07 08:16:45 nobody said you have to know it by hard Apr 07 08:16:49 heart* Apr 07 08:16:51 <_av500_> by soft Apr 07 08:16:56 300 - 3.6MM Apr 07 08:17:12 thats right.. i just said it was hard! Apr 07 08:17:12 <_av500_> below 300 you can GPIO is from user space :) Apr 07 08:20:01 wonder how many are avaialble. Apr 07 08:20:12 mranostay: TTL is ok, and actually helpful Apr 07 08:20:13 :-) Apr 07 08:20:32 * KotH doubts that the bone does actually do TTL Apr 07 08:20:54 well, its not -/+ 12V RS232 anyway. Apr 07 08:21:21 it's not 0/5V either :) Apr 07 08:23:28 mrpackethead: just take a 1$ uC with an usb port and let it do the serial port for you Apr 07 08:23:51 that is a real possiblity Apr 07 08:23:56 buecase if i do that Apr 07 08:24:01 all the work is largely done. Apr 07 08:24:02 :-) Apr 07 08:24:29 but why do you need exactly 250k? Apr 07 08:24:36 that's kind of an odd number Apr 07 08:24:46 (ok, not as odd as the usuall baud rates) Apr 07 08:24:53 oh, jsut because i wanted to do something different Apr 07 08:24:54 :-) Apr 07 08:25:04 I thought it might annoy the swiss Apr 07 08:25:21 E1.30 Apr 07 08:25:25 sorry E1.20 Apr 07 08:25:31 e? Apr 07 08:25:38 moin woglinde Apr 07 08:25:41 e1.20 is the reason Apr 07 08:26:03 mranostay: i think we found somethign KotH is not an expert on. Apr 07 08:26:10 lol Apr 07 08:26:11 Apr 07 08:26:17 gm Apr 07 08:28:13 hmm.. i see... odd backstage device standard Apr 07 08:29:16 DMX512, millions of devices using it Apr 07 08:29:39 i didnt say it isnt being used ;) Apr 07 08:29:45 sadly, the industry we work in has a habbit of creating stupid standards Apr 07 08:30:35 it's the same in every industry :-( Apr 07 08:31:10 Im hoping the work we are doign on E1.31 and E1.33 has drastically improved thigns Apr 07 08:31:20 thats the DMX over IP standard Apr 07 08:32:14 if other ip'izations of communication protocols are any reference, it will only get more complex Apr 07 08:33:02 unless there is someone on board who understands networking and has a big company backing him Apr 07 08:36:11 we have both. Apr 07 08:36:58 i and i think ( and hope ) we got it right Apr 07 08:37:02 so far, its going well. Apr 07 08:37:33 i hope it will Apr 07 08:38:25 does anyone know a good RSS stream on papers in electronics? Apr 07 08:41:48 is it on your web site KotH? Apr 07 08:42:07 on my website? Apr 07 08:42:28 yes.. i was guessing answers to your question Apr 07 08:42:33 ^^' Apr 07 08:42:44 KotH hm I think you must bee ieee member and in the electronics society Apr 07 08:43:24 yes i am, but there is too much that passes under my radar Apr 07 08:44:15 * KotH needs someone like av500, but not for funny embedded/linux stuff, but for serious electronics business Apr 07 08:44:40 becuase embbeded is not serious? Apr 07 08:44:44 mmm.. Tell TI that Apr 07 08:44:48 lol Apr 07 08:45:00 you know what av500 writes about all day :) Apr 07 08:45:21 sometimes KotH you come across really badly. Apr 07 08:45:39 hmm? what did i do wrong now? Apr 07 08:45:54 what is serious electronics business? Apr 07 08:46:07 I woudl say that embedded systems are serious Apr 07 08:46:17 ^^' Apr 07 08:46:20 and you just aid they are funny and not serious Apr 07 08:46:38 My staff hope that i think its serious Apr 07 08:46:54 mrpackethead hm are you CEO too? Apr 07 08:46:56 becuase the depend on it to be serious enough that their pay gets to them each month Apr 07 08:47:01 i didnt say that it isnt serious, but that av500 proxies the funny stuff that happens in the embedded and linux area Apr 07 08:47:19 as i say KotH, sometimes you come across poorly. Apr 07 08:47:35 o.O Apr 07 08:47:42 * KotH makes a note to become a native english speaker like mru Apr 07 08:48:03 woglinde: I'm teh photocopier filler upper, box filler, CTO and general what ever needs doing guy Apr 07 08:48:13 mrpackethead he wants a news aggregator for electronics stuff Apr 07 08:48:28 but I doubt that this exist in this form Apr 07 08:49:07 woglinde: I need to hire a CEO! Apr 07 08:49:17 lol Apr 07 08:49:32 it would be your boss Apr 07 08:49:35 than Apr 07 08:49:39 no. Apr 07 08:49:47 becuase i own 60% of the company Apr 07 08:49:48 :-) Apr 07 08:49:53 lol Apr 07 08:50:15 the 40% owner in effect is a semi CEO Apr 07 08:50:45 but we are growing to a point where we need more people Apr 07 08:50:53 and that sadly means some more managment Apr 07 08:51:04 mrpackethead: how many are you now? Apr 07 08:51:26 17 full time, and about 6 part time / casusal Apr 07 08:52:16 and how many do managment/team leader stuff? Apr 07 08:52:40 <_av500_> KotH: I'll block you now Apr 07 08:52:49 NOOOOOOOOOOO! Apr 07 08:53:18 2.5 Apr 07 08:53:37 we run a different from normal structure Apr 07 08:53:43 juup Apr 07 08:53:45 i'm really at the bottom of the pile. Apr 07 08:53:47 2.5 is pretty lean Apr 07 08:53:49 2.5 for 17 people Apr 07 08:53:51 hm hm Apr 07 08:54:09 you need more scrum master Apr 07 08:54:10 my job is just to make everyone elses job easier Apr 07 08:54:42 woglinde: does scrum work for electronics? Apr 07 08:54:42 <_av500_> mrpackethead: do you have a website? :) Apr 07 08:54:51 <_av500_> KotH: scream works Apr 07 08:54:56 www.stellascapes.com Apr 07 08:55:00 but its massively out of date Apr 07 08:55:04 koth why not? Apr 07 08:55:32 <_av500_> KotH: http://www.theinquirer.net/inquirer/news/2259381/arm-says-its-chips-and-linux-will-sweep-the-industry Apr 07 08:55:42 koth RUP for sure will not work Apr 07 08:56:50 <_av500_> mrpackethead: I read that as Stella's Capes :) Apr 07 08:56:51 we actuall are in teh process of getting our web site sorted out Apr 07 08:56:52 :-) Apr 07 08:57:48 woglinde: because it seems to be too much geared down for software development Apr 07 08:58:13 woglinde: the complexities and difficulties in hw development lie elsewhere... and i'm not sure whether scrum can manage that efficiently Apr 07 08:59:10 <_av500_> KotH: just let the HW be fixed in SW Apr 07 08:59:31 woglinde: actually, most of our hw design is in a way similar to RUP Apr 07 08:59:46 is done* Apr 07 09:00:27 _av500_: i find that mildly amusing :) Apr 07 09:02:05 <_av500_> RUP? Apr 07 09:02:43 rational unified process Apr 07 09:03:07 Rup. another bs system invented by beanies Apr 07 09:03:21 _av500_: can be sumarized as a glorified waterfall process Apr 07 09:03:33 destroys creativeity Apr 07 09:04:10 mrpackethead: depends on what you need Apr 07 09:04:22 waterfall is nothing more than reality really though Apr 07 09:04:29 mrpackethead: there are stuff where you need an elaborate and paperheavy process to keep things straight Apr 07 09:04:31 Hard to get to teh end without going there Apr 07 09:05:11 Agile development is where we work Apr 07 09:05:22 if you want to call it something Apr 07 09:05:43 mrpackethead: eg if you are doing medical, or even worse aerospace, then you first produce a lot of paper about the design and the risks the design involves, before you even start doing the schematics of the prototype Apr 07 09:07:00 <_av500_> KotH: and then you use the paper to burn the guy that mixed up the units Apr 07 09:07:07 juup Apr 07 09:07:09 yup. Apr 07 09:07:19 and thats why i got out of doign thigns that matter Apr 07 09:07:22 :-) Apr 07 09:07:27 funny thing: with space stuff, you can actually do that Apr 07 09:07:48 one project we are in, does have something around 5000 pages only for the proposal Apr 07 09:07:56 and jsut do fun non serious stuff... Apr 07 09:08:10 but that's esa.. their in the paper industry Apr 07 09:08:19 they are* Apr 07 09:08:27 meh.. english not working today Apr 07 09:09:49 mrpackethead: have you read "just for fun" by torvalds/diamond ? Apr 07 09:09:58 no. Apr 07 09:10:03 i recomend it Apr 07 09:10:10 probalwm is just for fun became serious Apr 07 09:10:20 when people wanted to buy what i did jsut for fun. Apr 07 09:11:47 poor boy! Apr 07 09:13:25 http://www.youtube.com/watch?v=GAt6A98lXQw Apr 07 09:13:42 put this on my front lawn one crhsitmas a while ack. Apr 07 09:15:38 then things got out of crontrol Apr 07 09:16:15 http://www.youtube.com/watch?v=3F9fOFOcr9o Apr 07 09:17:06 http://www.youtube.com/watch?v=WoiSgqnyyaU Apr 07 09:21:18 this si the sort of nuttyness we do Apr 07 09:21:24 see nothing serious Apr 07 09:21:37 and nothing that will kill anyone if it stops Apr 07 09:21:38 :-) Apr 07 09:28:20 ERROR: YouTube said: This video contains content from Warner Chappell and IODA, one or more of whom have blocked it on copyright grounds. Apr 07 09:32:28 no, all paly for me. Apr 07 09:32:37 we love this about youtbue Apr 07 09:32:49 they block everythign for the swiss Apr 07 09:32:50 :-) Apr 07 09:32:59 nah.. the germans have it worse Apr 07 09:33:19 is't .ch part of .de? Apr 07 09:33:19 at one time, youtube threatened the gema to block germany completely :) Apr 07 09:33:20 anyway Apr 07 09:33:46 or is it part of .fr, or .it? Apr 07 09:37:03 <_av500_> no Apr 07 09:37:08 <_av500_> .ch is on its own Apr 07 09:37:30 <_av500_> but they speak all of the above languages Apr 07 09:37:32 <_av500_> and some more Apr 07 09:37:44 thats what they tell the swiss to keep them quiet Apr 07 09:37:52 they even give them their own money Apr 07 09:38:12 but really.. they are europeans.. Apr 07 09:38:22 don't tell them, they might go on the rampage Apr 07 09:38:58 mrpackethead: do you have a sound system outside, so your neighbors get the full experience? Apr 07 09:39:11 depends.. Apr 07 09:39:15 at my house we do Apr 07 09:39:19 but i live in teh country Apr 07 09:39:35 next house is 800m away! Apr 07 09:39:50 many people run a small FM transimitter Apr 07 09:39:57 this is common in the USA Apr 07 09:40:04 eh.. Apr 07 09:40:13 and people tune to the music as they sit in their cars outside the show Apr 07 09:40:18 a small transmitter would cost you dearly here in .ch Apr 07 09:40:44 they are $80-$100 on ebay for a .5W thing Apr 07 09:40:47 that does the job nicely Apr 07 09:40:53 that's not the issue Apr 07 09:41:11 the swiss will have rules about such thigns no doubt Apr 07 09:41:12 :-) Apr 07 09:41:21 unlicensed transmission Apr 07 09:41:46 in NZ, we have a band and power limit where you can do these thigns Apr 07 09:42:01 i cant remember what the EIRP is Apr 07 09:42:04 but its not a lot Apr 07 09:42:10 but still useful to get you 200-300m Apr 07 09:42:28 you can pick any frequency between 101.0 and 101.9 Apr 07 09:42:47 well.. the fm radio spectrum in .ch is full, so any such device would compete with some radio station Apr 07 09:42:48 but there are no guarrentees things will be free from interfernace Apr 07 09:43:33 do you have digital FM ? Apr 07 09:43:47 DAB? sure Apr 07 09:43:51 they are implementing it here shorlty Apr 07 09:44:00 shortly? Apr 07 09:44:01 o_0 Apr 07 09:44:10 we are just in teh process this year of finally turning off the analog TV Apr 07 09:44:31 we've had digital tv for about 10 years i think Apr 07 09:44:45 but they are finally actually turning off the old analog Apr 07 09:44:45 .ch shut down analog tv in 2006 Apr 07 09:44:58 dab was introduced when i was still a kid.. dont know.. prolly early 90s Apr 07 09:45:14 one of the issues in NZ, is we have massive areas to cover Apr 07 09:45:19 juup Apr 07 09:45:25 with hardly anyone living there Apr 07 09:45:28 juup Apr 07 09:45:33 but we have to be abel to get them signal Apr 07 09:45:46 DAB was originally thought as means to free up more spectrum Apr 07 09:45:49 so, they stuck very large VHF transmitters on teh top of large mountians Apr 07 09:46:14 we now have free satellite tv Apr 07 09:46:20 so, that mets teh govenrments obligations Apr 07 09:46:32 however, the 'free' satellite is high compresssed Apr 07 09:46:39 it looks gastly Apr 07 09:46:49 looks like a video coming down a 28k modem Apr 07 09:46:51 :-) Apr 07 09:46:57 lol Apr 07 09:47:02 but it's cheap! Apr 07 09:47:07 yup. Apr 07 09:47:16 we have UHF terreistial at home Apr 07 09:47:31 "supposably" we shoud'nt be able to receive it here Apr 07 09:47:42 however.. Apr 07 09:47:51 interstingly, although we still have UHF transmission, you dont see the yagis on the houses anymore Apr 07 09:47:55 i was unstatisified with that response. Apr 07 09:48:03 most people have cable .. and had it for decades Apr 07 09:48:23 the govenrment here is rolling out fibre to 85% of homes Apr 07 09:48:26 i think radio is the only thing that people still generally get over the air Apr 07 09:48:35 wow! Apr 07 09:48:41 who covers the cost for that? Apr 07 09:48:44 i think, that we will end up getting our TV Apr 07 09:48:48 "tax payers" Apr 07 09:48:58 is it worth it? Apr 07 09:49:18 well, i might have a fibre that is capable of 40Gbps-1 Apr 07 09:49:26 i man, .nz is such sparsly populated, getting fibers to every hose will cost a damn lot Apr 07 09:49:28 but what the hell is on the other end? Apr 07 09:49:41 thats why its only 85% Apr 07 09:49:42 your standard shitty link to asia and the us? Apr 07 09:50:00 wwe actually have pretty good connectitiyt o the US Apr 07 09:50:21 theres a dual ladder WDM fibre system Apr 07 09:50:47 hooks, Australia, USA, hawaii, Fiji together Apr 07 09:51:02 and there is a new fibre going up to Singapore Apr 07 09:51:18 Once you get to singapore Apr 07 09:51:23 you can get *anywhere* Apr 07 09:51:42 well.. but rtt is shitty to europe Apr 07 09:51:43 95% of the fibre in teh ocean right now is 'dark' Apr 07 09:52:09 250ms or so i'd guess Apr 07 09:52:33 more Apr 07 09:52:46 most of singabpore is routed over the us Apr 07 09:52:52 -b Apr 07 09:54:02 hmm.. 380ms from here to www.sg Apr 07 09:54:05 not too bad Apr 07 09:54:50 i used to do nasty things to my junior engineers Apr 07 09:55:07 i had some good latency/jitter tools Apr 07 09:55:08 :-) Apr 07 09:55:59 eh.. you're mean! :) Apr 07 09:57:12 coudl simualte routers gettign very large delays in them Apr 07 10:56:05 Hello. I need some advice on using the Beagle wit OpenCv for a project. Apr 07 10:57:03 What I want to do is to use a camera and take a picture of someone's lips that will have 4 x red dots, 4 x green dots, and 4 x blue dots and return the X,Y cords of each Apr 07 10:57:19 This needs to happen about 5 to 10 times a second Apr 07 10:57:55 The camera will be positioned with lenses so it will only really see the lips for processing Apr 07 10:58:36 all the students got their assignments it seems. or are they already getting due? Apr 07 10:59:03 No. This is a project to create real time lip synciong and emotion pickup for animatronics Apr 07 10:59:56 If you have seen Avatar and know how they made the facial pickup - I am trying to do the same. I have already tried with a Rasp Pi but it does not have the processing power needed Apr 07 11:00:04 I'd start out by getting the camera to work on a desktop linux with opencv Apr 07 11:00:09 and then move that to the bone Apr 07 11:00:38 hm 5 to times should be possi ble Apr 07 11:00:44 ups 5 to 10 Apr 07 11:01:36 I am not sure how the Beagle compared to the R-Pi Apr 07 11:02:05 omsg hi, is there any one who worked on dsp devkit8500d?i need helppppp. Apr 07 11:05:26 zardari: in addition to random character duplication you could throw in question and exclamation markes and try repeating yourself about 20 times. I'm sure that will increase your chances for success... Apr 07 11:06:53 do you know how to do it? Apr 07 11:07:46 Woglinde: thanks for the info. trying to comare small portable board capabilites bewteen each other is never easy :) Apr 07 11:08:04 marcwolf_ thats not a 100% yes Apr 07 11:08:25 marcwolf_marcwolf_ but you have the dsp on the beagle Apr 07 11:08:37 besides it got not many love in the last time Apr 07 11:09:15 zardari ask your sail contact Apr 07 11:09:19 I understand - what I might do first is create the experiment on my normal desktop and then work down. I believe there are some faster camera options for the Beagle too (Leapord?) Apr 07 11:09:20 I am not that Apr 07 11:09:45 marcwolf yes Apr 07 11:09:56 leopard cam is fastest option Apr 07 11:10:15 ups Apr 07 11:10:18 sail Apr 07 11:10:19 lol Apr 07 11:10:33 zardari I meant ask your selling contact about help Apr 07 11:10:35 Either way - ita a method of travel :) Apr 07 11:12:57 am not concerned with the speed yet i want to know which way i use to transmitt video Apr 07 11:13:11 i mean how to stream video? Apr 07 11:15:49 marcwolf_ I tought you already have something ready, otherwise how could measure it on rpi? Apr 07 11:17:19 Yes - today I powered uyp a Rasp Pi and using the SimpleCV I was ttesting the speed of grabbing frames. After seeing how fast some of the example were runing esp the once that checked olors at pixel locations I realised it would be too slow Apr 07 11:18:31 Previously I was working with Wii IR Camera and strobing 4 camera's at a time. This might still be a possibility Apr 07 11:19:30 With the Wii - to get more than 4 positions one would have to wear the IR Leds rather than using reflective dots. Apr 07 11:20:23 bro,my devkit is in working condition m using angstrom linux tell me a way to stream video on angstrom? Apr 07 11:20:30 lunch now Apr 07 11:20:45 9:30pm here in Bris Au Apr 07 11:20:49 zardari like on anyothetr linux too Apr 07 11:21:19 how? Apr 07 11:21:24 zardari like marcwolf get it run on desktop linux and then its easy to switch embedded board Apr 07 11:21:36 otherwise you have no knowledge about tools at all Apr 07 11:21:40 till llater Apr 07 11:23:12 Many thanks for your advice.. Apr 07 11:23:22 i've done it on desktop linux using vlc player g streamer,but when i mv to embedded sys i get a problem of ramdisk bus error. Apr 07 11:31:42 ? Apr 07 11:31:45 ? Apr 07 11:31:47 ? Apr 07 11:31:47 ? Apr 07 11:31:49 ? Apr 07 11:31:50 ? Apr 07 11:31:51 ? Apr 07 11:31:52 ? Apr 07 11:31:53 ? Apr 07 11:31:54 ? Apr 07 11:31:58 ?? Apr 07 11:31:58 ? Apr 07 11:31:59 ? Apr 07 11:32:04 ?

Apr 07 11:37:21 zardaris read this http://www.catb.org/esr/faqs/smart-questions.html Apr 07 11:44:28 on devkit8500D using angstrom linux i made ramdisk.gz and now most of my application such as: mplayer aplay opkg giving bus error. Error mesage is: attempt to access beyond end of device. ram0: rw=0, want=134690, limit=131072 Apr 07 11:45:11 looks like your ram disk is to small Apr 07 11:45:26 or you do not have enough ram Apr 07 11:45:41 why do you need a ramdisk at all Apr 07 11:47:32 yup i made it agian increased memory from 16MB to 80 MB,m player was working with 16MB but with 80MB ramdisk its giving an BUS ERROR. Apr 07 11:49:07 its possible the ramdisk is mapped to reserved array Apr 07 11:49:21 ups area Apr 07 11:49:22 to install drivers and softwares m using ramdisk without ramdisk it does'nt operate even. Apr 07 11:49:31 ? Apr 07 11:49:52 mostly you only need a ramdisk to get some storage medium up Apr 07 11:50:03 than the rest can be loaded from the storage medium Apr 07 11:50:36 and 80 mb ram disk is quiet big Apr 07 11:52:29 so what should i do now ?i even hav tried with a 30 MB ramdisk its not working giving same error,total ram=512mb Apr 07 11:52:47 do you have none sdcard or internal nand? Apr 07 11:54:06 sd card of 4gb is used and it also have internal nand. Apr 07 11:56:05 so why you need all stuff inside the ramdisk? Apr 07 11:57:51 ramdisk contains my rootfs file if i don't use ramdisk my sys does nt operate. Apr 07 11:58:00 ? Apr 07 11:58:34 why is it not possible for you doing the following Apr 07 11:59:07 put your image to sdcard Apr 07 11:59:35 use the ramdisk to bring up the sdcard use ramdisk chroot mechanism to work further on sdcard Apr 07 11:59:54 thats how all other is doing it Apr 07 12:00:09 besides most do not need a ramdisk anymore Apr 07 12:00:49 what is chroot mechanism ? Apr 07 12:01:53 its mounting the / from sdcard to the actual / chroot into it runs init from it Apr 07 12:02:40 zardari you should unpack a ramdisk from your desktop distribution and look the commands which will be executing Apr 07 12:06:10 ok i try it Apr 07 12:06:32 is the ramdisk provided by your supplier? Apr 07 12:06:40 or did you wrote it yourself? Apr 07 12:07:23 first i used the provided ramdisk,then i made my own. Apr 07 12:08:39 and why did you put all stuff into the ramdisk? Apr 07 12:10:10 i follwed the manual procedure i don't knw any alternative thts why am here:) Apr 07 12:10:57 * ogra_ would try to boot with noinitrd and root= pointing to the SD Apr 07 12:11:06 (on the kernel cmdline) Apr 07 12:11:44 ogra_ maybee its not possible with the devkit Apr 07 12:11:56 might be, thats why i said "try" :) Apr 07 12:12:49 generally initrds just slow down your boot ... they are important for general purpose distros where you might change bits and pieces ... but embedded usually doesnt urgently need one Apr 07 12:42:19 on devkit8500D using angstrom linux i made ramdisk.gz and now most of my application such as: mplayer aplay opkg giving bus error. Error mesage is: attempt to access beyond end of device. ram0: rw=0, want=134690, limit=13107 Apr 07 13:38:16 Hey guys, I havec ompiled kernel and RFS according to the angstrom "how to" on their webpage, but when I let the BB boot, it shows Emergency mode, and I cannot even "mkdir folder". It logs - Read-only filesystem. Thanks for any advice.

Apr 07 15:14:07 fix your filesystem Apr 07 15:46:17 koen: am I doing the right things with the pull requests to http://github.com/Angstrom-distribution/meta-ti? Apr 07 16:17:20 jkridner_: did you send the patches to beagle-alpha as well? Apr 07 16:18:12 nope. can I just send URLs to the github pull requests? Apr 07 16:18:47 just do like everyone else and send the patches as well Apr 07 16:19:39 and run newly created recipes through oe-stylize.py first Apr 07 16:21:41 ka6sox: did you see https://github.com/raumfeld/linux-am33xx/commit/169d1157aef52f2e3a91c2f53aeacfffd455d90f already? Apr 07 16:24:00 koen, have not seen it...will see what detheridge has done and how this fits. Apr 07 16:26:11 koen, iirc there was a ML item where people were seeing swapping of buffers (probably the interrupts being late) that this might help. Apr 07 16:58:43 morning Apr 07 17:07:44 mranostay, it was minor...you can still type. Apr 07 17:46:18 jkridner_: I fixed up the bone101 recipe myself and doing a build with your 3 commits Apr 07 17:46:58 k, which repo? Apr 07 17:47:33 guess that recipe should be super simple. what on earth could I have done wrong with that one even after running it through oe-stylize? Apr 07 17:48:21 I squashed them down to 2 patches when I sent to the mailing list. Apr 07 17:48:48 oh uh jkridner_ is here Apr 07 17:49:04 using 'git send-email' is a PITA with my current setup, but can do. Apr 07 17:50:14 jkridner_: git send-email understands gmail: http://hastebin.com/kanavuwefe.avrasm Apr 07 17:50:25 jkridner_: it will ask for your password before sending Apr 07 17:50:29 * jkridner_ has used it through gmail many times. Apr 07 17:50:50 k Apr 07 17:51:07 jkridner_: you did test the recipes, right? Apr 07 17:51:16 so I cloud9 still works? Apr 07 17:51:45 I didn't add bone101 to the image, only loaded the built .ipk Apr 07 17:51:59 ok Apr 07 17:52:21 didn't touch anything with cloud9... only what gets dropped into /var/lib/cloud9 Apr 07 17:53:48 bonescript is now global, can cloud9 still run bonescript apps? Apr 07 17:53:51 latest beaglebone-getting-started might be too big with the apps. guess we should leave them out. they'd be kinda nice to know there is a known-good browser when walking up to windoze machines. Apr 07 17:53:55 yes. Apr 07 17:54:09 I did test that I can create and run apps in cloud9. Apr 07 17:54:42 I'll poke Eric tomorrow about the meta-browser backport status, if not I can replace the repo in layers.txt with a fork for the time being Apr 07 17:55:23 * koen stabs 3.9-rc5 for being *$#(@*#(@#$ broken Apr 07 17:55:25 jkridner_, I've been testing what darren did this weekend so I've had no time to work on the musb stuff. Apr 07 17:55:40 DT based boot for beagleboard-xM only works without DSS2 Apr 07 17:55:49 too late for USB patches. :( Apr 07 17:55:57 HDMI audio or bust! Apr 07 17:56:06 focusing on that. Apr 07 17:57:17 koen: I might have confused myself in my testing of apps in cloud9 with a localized copy. I can run from the command-line, but in Cloud9 it isn't picking up NODE_PATH. :( Apr 07 17:57:31 sorry... was a late night after all. Apr 07 17:57:51 looking at how to fix now Apr 07 17:58:20 you might need to add an EnvironmentFile=/etc/profile.d/node into the cloud9 recipe Apr 07 17:58:28 s/might/will/ Apr 07 17:58:59 I'm not sure if our version of systemd can already do profile directories, but single files work Apr 07 17:59:32 in the [Service] section Apr 07 18:00:29 hmmm... didn't work with the existing /etc/profile.d/node.sh I dropped in there. Apr 07 18:02:12 that's for logged in users, not for daemons Apr 07 18:03:41 is there difference in the syntax if you specify the file using EnvironmentFile? Apr 07 18:04:11 googling just seems to show up pretty much the same thing, but no 'export' typically Apr 07 18:04:30 EnvironmentFile=/etc/profile.d/node.sh should do what we need Apr 07 18:04:55 that what I tried. not sure what is up.... Apr 07 18:04:57 oh, wait... Apr 07 18:05:01 I know what is up... Apr 07 18:05:11 node is invoked within cloud9.... Apr 07 18:05:16 not using the node4. Apr 07 18:05:28 need to look at the environment picked up within cloud9 Apr 07 18:11:05 jkridner_: should we extend the node4 patch with module.paths.push(" or a wrapper? Apr 07 18:11:14 (or patch node4 to add it globally) Apr 07 18:11:59 we don't want to extend node4... we want to extend the main node. Apr 07 18:12:13 oh, you mean the same patch Apr 07 18:14:08 as a quick test, I made a /usr/bin/nodeX with #bin/sh\nNODE_PATH=/usr/lib/node_modules node $@ and put nodeX in ide.js---that worked Apr 07 18:14:21 you probably have a much better idea of what is clean Apr 07 18:15:24 so install that wrapper, change the patch to point to that wrapper, right? Apr 07 18:15:47 that's the approach I just tested on the system. Apr 07 18:16:41 is that on my to-dos then? Apr 07 18:17:26 * jkridner_ still wants to try to add 'dtc' and 'pasm' too. :( Apr 07 18:21:55 koen: do I need to give up on SYSFS for PWM for the release? Apr 07 18:22:43 you can try to extact the pwm bits from the replicape patch and test those Apr 07 18:22:52 (and then test an LCD with pwms as well) Apr 07 18:23:25 My BB stucks on-> usbcore: registered new interface driver smsc95xx... using 3.2.28 kernel, have you met this somebody? There is already a thread(https://groups.google.com/forum/#!topic/beagleboard/CKtPRRZtWoU) but no answer Apr 07 18:24:12 k, so testing the same kernel with an LCD3 A2 would cover that requirement? Apr 07 18:24:33 it should Apr 07 18:24:39 koen: thanks for the advise before, it helped to a point Apr 07 18:24:51 jkridner_: btw, something like http://www.hobbyking.com/hobbyking/store/__6320__TURNIGY_5_7_5A_8_42v_HV_UBEC_for_Lipoly.html works great combined with 5-6 AA batteries Apr 07 18:25:11 k, I'll give it a go. messing with the USB is definitely a non-starter at this point, but I still need to clean up a lot around bonescript too. Apr 07 18:26:01 * jkridner_ scrolls back to read about meta-browser Apr 07 18:26:24 ah... to use a fork if the patch isn't accepted. Apr 07 18:26:38 jkridner_: I've already accepted the fact that we'll need to do a new image release in a month from now with usb, audio, etc Apr 07 18:27:11 well, with 20,000+ boards out there with this image, I think we want to shove as much in as we can. Apr 07 18:27:24 jkridner_: the patches are in their test env now, not sure how long that takes Apr 07 18:27:41 jkridner_: I agree we need to fix as much as possible today/tomorrow Apr 07 18:28:02 USB DMA and Audio seem like survivable casualties (to be resolved with opkg update; opkg install kernel...), but the out-of-box needs to be smooth. Apr 07 18:28:57 the fact that I'll be doing all of my training over the next 3 months using stock images makes me a bit nervous too. :) Apr 07 18:29:38 ...and all the examples in the book have to run out-of-the-box... Apr 07 18:29:51 jkridner_: borrow some rum from prp^2 Apr 07 18:30:02 that has been a lot of fun testing over the last couple of weeks. Apr 07 18:30:16 PWM is the nightmare right now. Apr 07 18:30:36 no USB/audio in the book. :) Apr 07 18:32:48 jkridner_: I pushed out all the pending patches, minus the chromium ones Apr 07 18:32:57 jkridner_: and you really need to do git commit -s Apr 07 18:33:39 k Apr 07 19:00:19 koen: where is your FRI2 image located? Apr 07 19:02:21 mranostay, do Myth's have images? Apr 07 19:02:45 well the myth is in my closet Apr 07 19:06:20 picture with today's newspaper or its a myth... Apr 07 19:07:40 mranostay: http://dominion.thruhere.net/koen/angstrom/fri2/ Apr 07 19:35:25 *sigh* how do I mount the vfat partition for beagle when I have it in sdcard image in a file Apr 07 19:35:47 looks I am to stupid for losetup Apr 07 19:42:12 pop it out? :) Apr 07 19:43:15 ? Apr 07 19:44:02 woglinde: google losetup :) Apr 07 19:44:03 sorry, channel changed position on my channel bar Apr 07 19:44:34 kpartx is handy Apr 07 19:44:38 solved Apr 07 20:00:44 woglinde: kpartx -a -v file.img Apr 07 20:01:08 woglinde: I'm amazed how unknown kpartx is, very few people know about it Apr 07 20:01:14 require an enthusiam boost today Apr 07 20:01:18 its monday Apr 07 20:01:24 and i have stuff i have to finish Apr 07 20:01:26 :-( Apr 07 20:03:08 koen yes google helped Apr 07 20:03:40 koen is the kernel 3.7 know to work on beaglexm? Apr 07 20:03:55 * woglinde tries to setup jenkins test stuff Apr 07 20:04:42 latest kernel that is workign well is 3.2 Apr 07 20:04:50 3.7 should at least boot Apr 07 20:04:59 * koen is trying to get 3.9-rc5 working on xM today Apr 07 20:08:27 * woglinde wonders why we do not have patched u-boot for beagle in oe Apr 07 20:08:29 ups Apr 07 20:08:30 qemu Apr 07 20:19:45 hm why the hell bitbake do not read the linux-mainline 3.7.0 bb Apr 07 20:25:44 hm ah its 3.7 only Apr 07 20:29:42 hm no Apr 07 20:34:37 hm ah compat I guess Apr 07 20:38:35 okay another case solved Apr 07 20:38:48 re mrpackethead Apr 07 20:39:10 hi woglinde Apr 07 21:09:02 troll troll troll Apr 07 21:09:49 hi mru Apr 07 21:21:43 mru how was the bar? Apr 07 21:23:02 the bar? Apr 07 21:24:13 hm ah plane Apr 07 21:25:59 koen: is there a method for updating /etc/environment? Apr 07 21:28:01 plane did have booze Apr 07 21:30:40 koen: the reason EnvironmentFile didn't work for me was because it was the wrong format.... it doesn't want a script, but key=value pairs Apr 07 21:31:04 If I create /etc/node_env (name to use???) and put that in the service files, it works fine. Apr 07 21:42:57 wmat: that cable internet video is so true :) Apr 07 21:43:19 mranostay: no doubt Apr 07 21:43:55 mranostay: did he say "oligobble"? Apr 07 21:44:31 hmm i would like to think so Apr 07 21:45:28 heh, optimum cockbag levels Apr 07 21:45:59 yep, you can oligobble down our balls, you're paying for it Apr 07 21:47:51 wmat: for the tech center of the world the internet here really blows :) Apr 07 21:48:47 it blows everywhere, just at different speeds Apr 07 21:49:00 at pricepoints Apr 07 21:49:02 *and Apr 07 21:49:16 good nite Apr 07 21:49:54 what weirdo timezone are you in? Apr 07 21:52:25 cest probably Apr 07 23:30:38 koen: do you have any hints on how to make 'dtc' using the patched kernel sources within the linux_mainine recipe? Apr 07 23:55:41 sigh. http://pastebin.com/N67PM1u7 Apr 07 23:59:47 urgh. seems it was just a naming thing. Apr 07 23:59:51 maybe I have it now. Apr 08 00:11:12 hmmm pinmux didn't get set properly for some reason Apr 08 00:17:23 argh... devicetree is so annoying to debug!!! Apr 08 00:17:50 no warnings about why pinmux wasn't set :( Apr 08 00:18:20 I'm guessing that pwm_test is missing the pinctrl calls, but I wish I knew Apr 08 00:18:47 I don't even know how someone is supposed to know what the drivers are meant to do with all of this data thrown at them. :( Apr 08 00:26:53 k, I can see clearly now that pinctrl isn't being called in pwm_test and needs to be. applied patch and building now. Apr 08 00:27:45 wmat: unicorn hunting is the national sport in North Korea mind you :P Apr 08 00:55:07 mranostay, I guess Intel doesn't love me... Apr 08 01:01:08 jkridner_: which board files warn when a pinmux isn't set? ;) Apr 08 01:01:49 but I can figure out where to add printfs for those. :) Apr 08 01:01:53 if your driver doesn't print a warning when pins aren't set from the driver then it's doing something wrong Apr 08 01:01:59 not that that isn't laborious too Apr 08 01:02:02 all the other drivers print a warning Apr 08 01:02:17 yeah, pwm_test is crap Apr 08 01:02:52 oh, that's the TI thing ,right? Apr 08 01:03:06 ka6sox: we all love you does that count? Apr 08 01:03:51 snif...yes... Apr 08 01:03:55 it isn't for end users... just for kernel testing... Apr 08 01:04:11 of course, if it is needed for testing... wouldn't you expect end users to need it? Apr 08 01:04:13 :( Apr 08 01:04:35 rebooting now with updated pwm_test that calls pinctrl Apr 08 01:04:51 jkridner_: I see "unable to select pin group. PWM not muxed right" Apr 08 01:05:05 in the version i just googled Apr 08 01:05:35 http://hipstercircuits.com/wp-content/uploads/2013/03/pwm_test1.c Apr 08 01:05:40 k. I could figure out that it wasn't muxed right by looking at the muxes... Apr 08 01:05:57 I just really get wrapped around the axle to figure out where these things are supposed to happen. Apr 08 01:06:15 step away for a day and I forget it all. Apr 08 01:06:17 the call always happens in probe() on all the drivers Apr 08 01:06:26 it's pretty much boilerplate stuff Apr 08 01:06:38 except people like to print varying messages to confuse everybody Apr 08 01:07:30 that might only be the updated one... I just applied his patch. Apr 08 01:08:11 that the best thing about out-of-tree drivers..there's so many and of varying quality Apr 08 01:12:44 heh Apr 08 01:12:49 it is just odd to me that there isn't a pinmux driver. panto's pinmux-helper makes one when there isn't a driver to call the pinmuxes, but the architecture is a bit wonky to me Apr 08 01:13:29 er, I guess pinctrl is a driver, but you can't load devicetree parameters for it without having some other driver's probe function actually make the calls. Apr 08 01:13:37 really freaky if you ask me. Apr 08 01:14:21 can nodejs help here? Apr 08 01:14:25 I mean, if I give you the pinctrl parameters and there is a pinctrl driver, why can't you use them? why does every driver need to know about pinctrl? Apr 08 01:15:30 what you need is a pinmux deconflicter. Apr 08 01:15:50 jkridner_: pinctrl is a kernel subsystem Apr 08 01:16:06 something that says NO...Bar Driver can't have a Pin that FOO driver is using. Apr 08 01:16:34 it provides an api for client drivers to claim resources they need Apr 08 01:17:02 mdp, are we using it Apr 08 01:17:22 ka6sox: some drivers use it, others should. Apr 08 01:17:30 ka6sox: on upstream stuff, yes. jkridner_ is using a bad driver Apr 08 01:18:06 jkridner_: so, the reason why is that pins are resources just like all the other resources you are used to drivers claiming Apr 08 01:18:08 I don't think our hdmi audio is using it. Apr 08 01:18:18 mem, dma, gpio _signals_, etc. Apr 08 01:18:23 the concept is still a bit broken to me, but it'll get worked out. Apr 08 01:18:47 ka6sox: it depends on a lot..none of that is upstream so it doesn't get good review Apr 08 01:19:12 I'm fine with a driver being aware and complaining, but as a kernel user, if the pin isn't claimed I should be able to configure it. Apr 08 01:19:35 the audio drivers were claiming i2c1 and setting it up when it had NOTHING to do with that. Apr 08 01:19:40 needing to create a consumer for it is a pain. Apr 08 01:20:14 the helper that panto created is an interesting stop-gap, but the interface for providing the information to the kernel is cumbersome. Apr 08 01:20:15 ka6sox: bug Apr 08 01:20:42 jkridner_: you know I already pointed koen to the upstream thing that allows you to select pin groups from userspace Apr 08 01:20:45 * jkridner_ is sad HDMI audio won't make it into the release Apr 08 01:20:48 he said he integrated it Apr 08 01:21:07 * jkridner_ doesn't know where to look for that. Apr 08 01:21:17 jkridner_: these corner cases you bring up just lack developers Apr 08 01:22:07 but then, eventually they've all been addressed as I just mentioned Apr 08 01:23:02 I'm a little confused as to what you think is missing still Apr 08 01:25:31 jkridner_, I'm sad too. Apr 08 01:26:29 mdp: /sys/kernel/debug/omap_mux was easy to use for components that didn't have completed drivers. Apr 08 01:27:00 mdp: I think what is missing is simply the system integration components and I find they are harder to put together then I think they should be... Apr 08 01:27:07 for example, if you want to use a pwm. Apr 08 01:27:33 * jkridner_ has to deal with running out of eMMC space now. :( Apr 08 01:27:51 not sure if it is my work that has taken all the space. Apr 08 01:32:26 jkridner_: it's been known that omap_mux was gone for eons now…why just bringing it up now? Apr 08 01:33:40 not picking specifically on you…it's just been a known problem from the beginning and nobody cared Apr 08 01:34:33 surely nobody expected people from other architectures to notice some omap-specific hack interface buried in mach-omap/ Apr 08 01:34:56 omap folks should have been reviewing and commenting appropriately if it was important Apr 08 01:35:04 this doesn't seem to be headed anywhere. Apr 08 01:35:40 well, this is a kernel change from 2011 is my point Apr 08 01:36:05 can you tell me if you are aware of the patches koen brought in late last week? Apr 08 01:36:14 I'm not Apr 08 01:36:22 no audio on the next gen bone? Apr 08 01:36:44 thru the hdmi it seems Apr 08 01:36:52 the other driver still works. Apr 08 01:37:00 thurbad: it'll have to be a download. Apr 08 01:37:04 the DVI+Audio. Apr 08 01:37:06 for the hdmi Apr 08 01:37:13 ah... :( Apr 08 01:37:30 mdp: I see pinconf-groups, but it has a limited number of groups. Apr 08 01:37:39 .... and I'll need to look up how to add to it. Apr 08 01:39:47 http://www.spinics.net/lists/arm-kernel/msg235412.html Apr 08 01:48:04 k, pinconf-config isn't there as of the build I have installed. I'll see if it is on the new build here. Apr 08 01:48:28 as soon as I can truncate some of my sloppy massive git history. **** ENDING LOGGING AT Mon Apr 08 02:59:58 2013
