**** BEGIN LOGGING AT Tue Mar 26 02:59:58 2013 Mar 26 03:01:47 i suppose small antenna can be a factor Mar 26 03:02:41 ds2, I *did* say a biiiiiiiig antenna for 60khz Mar 26 03:07:08 so for practical sizes, WWV is better Mar 26 03:16:43 ds2, as long as it switches frequencies periodically. Mar 26 03:36:26 SONOFA Mar 26 03:36:46 need to route ONE trace on a densely-packed board. Mar 26 03:37:03 is there any info regarding the sgx module on the next-gen beaglebone yet? Mar 26 03:37:40 what kind of info? Mar 26 03:37:52 it'll be the same SGX as current Bone. Mar 26 03:37:55 eh, I really didn't want to route that trace anyways Mar 26 03:37:58 just clocked faster. Mar 26 03:38:04 speed.. say compared to the xM Mar 26 03:38:32 I thought the current bone had no graphics Mar 26 03:38:52 current Bone has SGX graphics, just no DSS. Mar 26 03:39:00 you use the LCDC for display. Mar 26 03:39:09 ah Mar 26 03:39:12 SGX renders to framebuffer. Mar 26 03:39:50 clock speed not announced yet, but expect something in the range of xM. Mar 26 03:40:11 yes, I understand that.. just ported ogre3d 1.8 to fb0 on a 3530 as a matter of fact :) Mar 26 03:40:40 nice. should be able to use it on Bone and next-gen Bone as well. Mar 26 03:40:52 note, there is currently an issue with the display driver on the newer kernels. Mar 26 03:41:11 you might have to run 3.2 for a while or integrate an old-style framebuffer driver. Mar 26 03:41:33 I don't need newest kernel.. still using 2.6.32 on our current board Mar 26 03:41:38 the driver we are using now for 3.8 is a DRM driver which has some nice features and works better for connecting up lots of various resolution monitors. Mar 26 03:41:48 wow! 2.6.32! Mar 26 03:42:20 got a few backported 2.635 and 2.6.38 features in it Mar 26 03:42:32 but the core is still 32 Mar 26 03:42:55 well, then you shouldn't likely have a lot of problems. Mar 26 03:46:35 I'd like to convince my boss to get out of the business of maintaining custom boards, but without any numbers that's not likely to happen Mar 26 03:47:27 if we could become modular and only support our proprietary hardware I'd be a happy camper Mar 26 03:57:21 interesting.. current white bone srm says nothing of sgx Mar 26 03:59:15 I take that back.. there's a block diagram that sows it but lists no details :/ Mar 26 03:59:27 who cares Mar 26 03:59:29 that block is F'ed Mar 26 04:01:21 ? Mar 26 04:09:07 ? Mar 26 04:13:39 TRM for the dm3730 and am3359 both say 20M polies per second is the next-gen bone going to be faster still? Mar 26 05:21:42 <_av500_> ? Mar 26 05:52:43 _av500_: howdy Mar 26 05:52:55 angles okay now? :) Mar 26 06:13:19 someone kick inmap and tell them that their machine is falling over. Mar 26 06:14:40 * mranostay pokes av500 or jkridner Mar 26 06:14:55 ? Mar 26 06:18:57 see the spam above? :) Mar 26 06:19:35 i haz no op Mar 26 07:23:04 new meat scandal! http://i.imgur.com/mrhDF0U.jpg Mar 26 07:23:21 seen it in local Lidl store this morning Mar 26 07:25:53 old Mar 26 07:25:59 :( Mar 26 07:38:08 [kernel] koenkooi pushed 1 new commit to 3.8: http://git.io/niC0FQ Mar 26 07:38:08 kernel/3.8 2d13a60 Koen Kooi: 3.8: more tester patches and 2 additional fixes for HDMI timings when using LCDC...

Mar 26 08:49:03 lo¡ Mar 26 08:50:44 tristate Mar 26 09:03:08 jojo Mar 26 09:24:39 Hi! Mar 26 09:25:00 How to get rid of '+' in kernel name http://arago-project.org/git/projects/?p=linux-am33x.git;a=summary Mar 26 09:25:39 uname shows 3.2.0+ Mar 26 09:32:16 yegorich: touch .scmversion Mar 26 09:41:43 koen: thanks. It helped! Mar 26 09:51:48 I am working on the beaglebone and tryging to configure TIMER1MS to use CLK_32KHZ (the clock derived from per pll). by default it's configured to bypass and use CLK_M_OSC (24 Mhz I think). Can U just change the value of the CLKSEL register ? What happens is that the first time I do it it looks good. but after a reboot I can't write my timer registers any more. Mar 26 09:52:31 and I don't get that. is there some gating involved and it that clock also the functional clock for the timer? Mar 26 10:01:49 powned macosx-user Mar 26 10:02:18 aholler: going for the easy prey? Mar 26 10:02:19 ;) Mar 26 10:02:34 I meant inmap Mar 26 10:04:01 I don't have rotten fruits, they end up in the trash bin here Mar 26 10:04:39 :q Mar 26 10:07:10 jackmitchell: apple never understood that non-us-users don't want unusable keyboard layouts Mar 26 10:08:40 aholler: I agree, I'm no Apple fan, but I am a vim fan... ;) Mar 26 10:09:33 maybe :q! works ;) Mar 26 10:16:24 aholler: well.. you're punished by german keyboards.. the swiss german layout is actually pretty decent :) Mar 26 10:18:56 I never feeled punished. I'm just happy with what I'm using and don't feel the need to adopt some borked apple-layout which would result in broken fingers (like when using emacs) Mar 26 10:19:48 isnt using emacs like asking for knots in your fingers? Mar 26 10:20:42 aholler: wrt emacs: http://lwn.net/Articles/540368/ :) Mar 26 10:21:00 ...."Automate process processes", he said. Things like coding standards, static analysis, spaces vs. tabs, or detecting the use of Emacs should be done automatically... Mar 26 10:23:51 * KotH wonders where av500 takes the time to read all those webpages Mar 26 10:28:28 it's just a matter of priorities Mar 26 10:32:10 KotH: I dont Mar 26 10:32:34 but I read a complaint that poor emacs was singled out :) Mar 26 10:33:27 also, this Google Reader that nobody uses is quite useful in the tram :) Mar 26 10:37:53 av500: I reckon that could be taken in two ways Mar 26 10:38:07 it could mean that certain settings are applied for when it finds emacs Mar 26 10:38:23 in order to suit the emacs environment better... Mar 26 10:38:49 but I'm not an emacs user, so I could be talking nonsense ;) Mar 26 10:39:24 jackmitchell: :) Mar 26 10:39:26 the equivalent of the vim tags which set the tabs, spaces and other settings Mar 26 10:39:35 emacs detected, code deleted Mar 26 10:39:56 i've just tried mainline u-boot and koen bone patch stack for 3.8 and I get overcurrent shutdowns when powering it via USB. is that a known problem? Mar 26 10:40:05 yes Mar 26 10:40:05 yes Mar 26 10:40:07 I don't know if it's right, bit I think people all jumped on the bandwagon rather quickly Mar 26 10:40:16 put that magic i2c command in your uEnv.txt Mar 26 10:40:18 OMG EMACS HATER Mar 26 10:40:33 av500: I can't find that magic i2c command, can you post it again? Mar 26 10:40:40 yes Mar 26 10:40:43 it seems there were patches in ti's u-boot to configure the usb current limit to 1300mA. but now we don't have that anymore Mar 26 10:41:27 preenvcmd=i2c mw 0x24 1 0x3e Mar 26 10:41:31 any specific reason they were removed? Mar 26 10:41:34 uenvcmd in your case Mar 26 10:43:31 or why they are not in mainline u-boot or as patches in meta-beagleboard? Mar 26 10:44:48 maybe it will kill the other side of the cable Mar 26 10:45:16 hmm, ok... Mar 26 10:45:34 so everyone using 3.8 simply uses the i2c commands to change the limit? Mar 26 10:46:15 but I don't know. usually usb-hw has overcurrent detection. but there might exist some hw with errata, unusual, but it happens Mar 26 10:46:28 ;) Mar 26 10:47:27 so the correct way would be to check for !AC power and then use only lower frequencies in the bootloader and kernel Mar 26 10:48:03 bootloader is fine, its the kernel that makes it shut down Mar 26 10:48:10 av500: thanks for the hint :) Mar 26 10:48:12 shoragan: I never use USB power Mar 26 10:48:25 shoragan: otherwise I would have applied them to my uboot patch stack :) Mar 26 10:48:33 patches welcome Mar 26 10:48:37 its convenient when sitting on the couch Mar 26 10:48:37 koen: me nither, but i just was on the train and forgot to pack my powersupply Mar 26 10:48:42 only laptop and bone needed Mar 26 10:48:54 I agree USB power needs to work Mar 26 10:49:05 just explaining why I keep forgetting about the issue Mar 26 10:49:09 koen: it'd probably write patches for barebox, not u-boot Mar 26 10:49:25 but as you say, actually we need kernel fixes Mar 26 10:49:44 does the bone really need 1.3A? Mar 26 10:49:44 the kernel has an mfd driver to the PMIC Mar 26 10:49:55 shouldn't be hard to teach that about current limits Mar 26 10:50:03 aholler: there are only 500 and 1300 limits available in the pmic Mar 26 10:50:13 koen: yes Mar 26 10:50:18 speaking of which, it should also mux the right line to AIN7 so we can do onboard current measurement Mar 26 10:50:31 * shoragan needs to catch the next train Mar 26 10:50:43 thanks :) Mar 26 10:51:00 can you put such register writes in uEnv.txt... you could do it with boot.scr Mar 26 10:51:16 why does it even need more than 500mA? Mar 26 10:51:21 unenvcmd=i2c mw 0x24 1 0x3e Mar 26 10:51:25 thurbad: ^^^ Mar 26 10:51:35 -n Mar 26 10:51:40 aholler: 1GHz, emmc, hdmi, etc Mar 26 10:51:40 ah, cool Mar 26 10:52:04 isn't it possible to disable the power drawing stuff like hdmi, eth and such? Mar 26 10:52:11 sure Mar 26 10:52:14 patches welcome Mar 26 10:52:14 sure Mar 26 10:52:14 I do that on my borad-board Mar 26 10:52:21 why does one need more than 640K memory :) Mar 26 10:52:37 thurbad: because ppl are lazy Mar 26 10:52:53 and paper is expensive Mar 26 10:52:55 nice Mar 26 10:53:09 too less mru's which want to write assembler ;) Mar 26 10:55:45 I wonder if that ti-rtos does run the bone Mar 26 10:55:54 +on Mar 26 10:56:07 bios? Mar 26 10:56:09 yes, it does Mar 26 10:56:39 I've never looked at it, just seen it yesterday ;) Mar 26 10:58:14 I might try it with the launchpad Mar 26 10:58:41 if I can use gcc and don't need a ide Mar 26 11:00:55 aholler : google lm4tools and use an arm-none-eabi toolchain, unless you need float Mar 26 11:01:18 I already have toolchains. Mar 26 11:01:34 then what would you need an ide for? :) Mar 26 11:01:46 the question was if ti-rtos can be compiled using gcc Mar 26 11:01:53 linux is an ide Mar 26 11:01:55 oh, sorry Mar 26 11:02:55 ti, as usual, advertises cc* Mar 26 11:03:34 hide! Mar 26 11:03:59 365MB? Mar 26 11:04:08 jupp Mar 26 11:04:10 one per day Mar 26 11:04:11 good luck on the launchpad with that :) Mar 26 11:04:43 don't know what's inside. sound like a enterprise java framework is inside Mar 26 11:04:47 back Mar 26 11:04:53 ;) Mar 26 11:04:55 front Mar 26 11:06:25 anyway, back to playing with nfc ;) Mar 26 11:06:59 aholler, heh Mar 26 11:10:34 panto: I just want to gather some missing knowledge and are utilizing the m24lr-discovery kit I have lying around Mar 26 11:11:43 its lying around here too Mar 26 11:11:49 aholler, what are you doing with nfc? Mar 26 11:11:57 where I currently don't even use the m24lr-part, just the cr95hf. Mar 26 11:12:06 but it seems to work Mar 26 11:12:08 I was dabbling with librfid a few weeks back Mar 26 11:12:16 panto: reading my geldkarte ;) Mar 26 11:12:36 is it rfid or nfc? Mar 26 11:12:39 there's a diff Mar 26 11:13:25 its ISO14443-A Mar 26 11:13:53 I'm not sure about the difference between rfid and nfc Mar 26 11:15:07 it's rfid Mar 26 11:15:50 where does rfid stops and nfc starts? Mar 26 11:16:07 err, no that nfc Mar 26 11:16:17 aholler, it's a grey area Mar 26 11:16:23 urg, looks like ogre is trying to use sse instead of neon... Mar 26 11:17:07 there was a request that gcc implement the -msse flag for arm Mar 26 11:17:48 its just SW Mar 26 11:25:18 aholler: nfc is the technology behind rfid... just nobody used it until someone needed a new buzzword Mar 26 11:25:50 av500: using libusb it's easy to control the cr95hf directly with the preflashed fw Mar 26 11:25:53 I always wondered as well, if NFC was anything more than a marketing term Mar 26 11:26:09 or if there was an actual protocol or such behind it Mar 26 11:27:28 well.. people turn the name of a technology into the name of a protocol and communication system Mar 26 11:29:44 nfc might be used to communicate directly between (active) devices, whereas rfid seems to apply to passive tags only. I think therefor they started to use nfc. Mar 26 11:29:59 s/nfc/the term nfc/ Mar 26 11:30:14 nah, there was always "active" RFID as well, e.g. car key fobs Mar 26 11:30:18 aholler: er.. no Mar 26 11:30:24 aholler: there are active rfid's as well Mar 26 11:30:32 have been around for decades Mar 26 11:31:10 although the distinction between "active RFID" and "RF" is lost on me ;-) Mar 26 11:31:31 anyway, two words for the same thing. Mar 26 11:32:10 biot: RF = classical radio system, RFID = modulation of the nearfield of an reading station provided field Mar 26 11:34:53 biot: or to put it differently: RF = two active transmitters, RFID = one active, one passive "transmitter" Mar 26 11:35:28 but how passive is a car key fob really? it's got its own battery after all Mar 26 11:35:45 morning Mar 26 11:36:22 maybe passive because it hasn't it's own intelligence and just works as an ID Mar 26 11:36:39 biot: car key fobs are actually not that passive.. most of those i know have active transmitters Mar 26 11:36:53 biot: there is one, i've seen that does not, but that was the exception Mar 26 11:37:16 there are two kinds of car key fobs Mar 26 11:37:16 so I guess they wouldn't really qualify as "RFID" as such Mar 26 11:37:31 the one with a button you press to (un)lock doors Mar 26 11:37:55 and the other which is merely required to be present in order to start the engine by a button on the dashboard Mar 26 11:38:04 biot: yes Mar 26 11:38:05 my keyfob has both systems Mar 26 11:38:19 come to think of it, mine works in the 800mhz range -- that's ISM, not RFID is it? Mar 26 11:38:31 you can run rfid in ism band Mar 26 11:38:34 biot: rule of thumb: if you can communicate without being near to some base station, then it's not an RFID Mar 26 11:39:31 it's like talking about coding styles Mar 26 11:39:33 biot: near as in "less than 2-5\lambda" Mar 26 11:39:44 KotH, define near Mar 26 11:39:53 * KotH just did ;) Mar 26 11:39:56 near on a cosmic scale? Mar 26 11:39:59 there's active rfid systems that go out to a few feet :) Mar 26 11:41:46 panto: most RFID systems work with 13MHz or somewhere in the 100kHz range... Mar 26 11:41:52 dammit, now I have to go sniff my car key fob, to be sure Mar 26 11:41:57 panto: you are well below 1 \lambda there Mar 26 11:42:06 the curse of having an inquisitive mind Mar 26 11:42:22 poor biot Mar 26 11:42:27 we pitty you Mar 26 11:42:32 heh Mar 26 11:43:17 biot: +1 Mar 26 11:44:37 sakoman, http://www.wired.com/dangerroom/2013/03/secret-service-reptile-aliens/?utm_source=twitterfeed&utm_medium=twitter Mar 26 11:44:52 crfoton what? Mar 26 11:45:28 hi alan_o Mar 26 11:46:26 hi panto Mar 26 11:46:43 apparently one of sakoman's kind works for the secret service Mar 26 11:47:06 sadly the bedop0er article revealing sakoman's true nature is gone Mar 26 11:50:06 surely those are responsible for the weather here too Mar 26 11:55:01 all those evil conspiracies Mar 26 11:56:14 Crofton|work: is it not logical to use a shape shifting alien to protect a shape shifting alien president? Mar 26 11:56:34 yes Mar 26 11:57:08 shape shift the clouds Mar 26 11:59:29 * alan_o makes a list of what he needs to get done today. Hacking is last ..... :( Mar 26 12:00:14 ahhh Mar 26 12:00:35 mdp: tough commute? Mar 26 12:04:00 btw., here's a good overview over rfid: http://www.youtube.com/watch?v=qWzyudL2rqY Mar 26 12:04:14 a video? sigh Mar 26 12:04:22 +1 Mar 26 12:07:53 biot, there's multiple variations of it Mar 26 12:08:04 ugh ugh Mar 26 12:08:06 nm Mar 26 12:08:37 alan_o, I managed to not spill my tea going downstairs Mar 26 12:08:47 it was uneventful Mar 26 12:08:50 no traffic Mar 26 12:12:44 mdp: what kind of tea you like these days? Mar 26 12:13:11 tea, earl grey, hot Mar 26 12:13:15 +1 Mar 26 12:13:21 I've been drinking Republic of Tea. Wife gets it at Whole Foods. Lots of flavors Mar 26 12:13:29 mru: +1 Mar 26 12:13:36 I like me some Earl too. Mar 26 12:13:45 I prefer Tesco Earl :p Mar 26 12:14:14 I find with Earl that it's better if I don't sniff the bag when I open it. Seems like if I do, then the tea doesn't taste as good (because I'm more used to the flavor from smelling it). Mar 26 12:14:34 it loses its Earlness Mar 26 12:14:34 we just had some twinings earl grey in the house...and felt like a change Mar 26 12:15:01 https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTLaIDMr4a9NQ_JWutiPTqLHlfEou2yHt-kb6K46a_xwjeNBHBx Mar 26 12:15:03 Twinnings is strange. They have some good stuff, and then they have some stuff that's horrible. Mar 26 12:15:19 I don't normally drink tea Mar 26 12:15:26 ynezz: is that the Earl himself? Mar 26 12:15:33 I like Redbush and Green Tea, along with my usual English Breakfast of course Mar 26 12:15:40 alan_o: it's his younger sister Mar 26 12:15:52 ynezz: hah! Mar 26 12:15:58 I tend to get mine from the local whittard shop Mar 26 12:16:20 I send my parents to india Mar 26 12:16:25 :D Mar 26 12:16:52 some cute girls on staff there :) Mar 26 12:17:25 mru: in India? Mar 26 12:17:37 at the local tea&coffee store Mar 26 12:17:44 never been to india Mar 26 12:17:52 though I'm sure there are cute girls there too Mar 26 12:18:07 you might have just gotten trolled :) Mar 26 12:18:16 unpossible Mar 26 12:18:21 jackmitchell: haven't read about Redbush before Mar 26 12:18:27 looks interesting Mar 26 12:18:44 mru: they've so much Earls there... Mar 26 12:18:52 in India? Mar 26 12:19:00 they got rid of them Mar 26 12:19:00 in that Chelsea store Mar 26 12:19:31 never been to the store in chelsea Mar 26 12:20:28 mru: are you in hantslug? Mar 26 12:20:34 whittard.com Mar 26 12:20:42 I'm in southampton Mar 26 12:20:51 they have a shop here Mar 26 12:20:58 with cute girls Mar 26 12:21:05 mru: I guess that's a no :) Hantslug is Hampshire LUG Mar 26 12:21:05 and tea Mar 26 12:21:13 looks yummy http://www.whittard.com/tea/black/english_breakfast_tea/english_breakfast_50_teabags.htm Mar 26 12:21:19 alan_o: oh, didn't know of that one Mar 26 12:21:28 afk Mar 26 12:21:47 mru: I have a friend in it and it just hit me that you might know him. Mar 26 12:21:54 guess not then Mar 26 12:22:05 I still might Mar 26 12:22:16 Ciemon Dunville? Mar 26 12:22:20 nope Mar 26 12:27:38 alan_o: it's like a naturally caffeine free English Breakfast, but with more "aroma" Mar 26 12:28:08 why are people so afraid of caffeine? Mar 26 12:28:16 that stuff is good for you Mar 26 12:28:26 especially at breakfast Mar 26 12:28:28 it is pre 1pm Mar 26 12:28:38 * mru makes another coffee Mar 26 12:28:39 post 1pm and I'm not sleeping well Mar 26 12:28:51 build your tolerance Mar 26 12:29:03 s/tolerance/dependence/ Mar 26 12:29:11 +1 Mar 26 12:29:17 I go on and off of caffeine Mar 26 12:29:21 jackmitchell: 4pm is my cutoff :) Mar 26 12:29:30 caffeine does nothing to me Mar 26 12:29:33 sadly Mar 26 12:29:45 I drink that stuff only for the taste Mar 26 12:29:52 unless I'm travelling, then I can drink it 24/7 and have no trouble sleeping Mar 26 12:29:54 english breakfast pre 1pm (4/5 cups), pure water 1pm - 5pm, post 5pm caffeine free green tea and Redbush Mar 26 12:29:57 The reason to be off of it is that if you're off, and you really need it, then it actually works, gives you a real kick. If you're on it every day it's just ho-hum. Mar 26 12:30:37 or beer post 5pm Mar 26 12:30:42 I'd rather be off all the time just for that, but it doesn't always work that way. After the first day, it's always, "man, I could use that again" Mar 26 12:30:49 koen: when I travel I usually dont drink coffee Mar 26 12:31:30 too much beer was had on Friday, so less of that this week.... :/ Mar 26 12:31:45 alan_o: you vary the level around any average for that effect Mar 26 12:31:59 like keep a moderate base level of 4 cups a day Mar 26 12:32:08 and occasionally spike it to 6 or 7 Mar 26 12:32:21 just scrolled by: https://lh4.googleusercontent.com/-cNFLB062rMs/UVGJqd-V-jI/AAAAAAAARXc/srNoBzH-24c/w497-h373/photo.jpg Mar 26 12:32:30 if I have 4 cups of coffee I get sick Mar 26 12:32:49 no tolerance there... Mar 26 12:32:55 lol av500 Mar 26 12:33:04 alan_o, you are a delicate flower Mar 26 12:33:28 yeah, I barely drink coffee; I just prefer tea Mar 26 12:33:56 jackmitchell: coffee is only worth the trouble if someone else has already made it. Mar 26 12:34:11 I have a fully automatic machine Mar 26 12:34:36 no effort required Mar 26 12:34:48 we have a nespresso here at work and it's ok, I indulge every so often Mar 26 12:34:57 aholler: looks like you dont need ccs to buildit Mar 26 12:35:02 but xdc and ti cc Mar 26 12:35:05 mostly when the fun flavours come in Mar 26 12:35:27 I find the nespresso "fun flavor" all awful Mar 26 12:35:31 +s Mar 26 12:35:36 +1 Mar 26 12:36:01 I liked the dark purple christmas one, but yeah on average you're best just sticking to coffee flavour Mar 26 12:36:24 http://www.youtube.com/watch?v=-f_dxLiuXuw Mar 26 12:41:52 aah, that last coffee really did the trick Mar 26 12:42:41 is it just me or is the thought about usians discussing coffee a bit weird... if not discusting? Mar 26 12:43:18 they wouldn't know good coffee if you threw it in their face Mar 26 12:43:40 * KotH can say the same about most europeans Mar 26 12:46:09 so as you can see, javascript is to blame for everything Mar 26 12:46:38 * KotH blames the viennese Mar 26 12:46:49 if they have surrendered, we would have good coffee in europe Mar 26 12:46:56 s/have/had/ Mar 26 12:47:04 have had Mar 26 12:47:36 KotH: +1 Mar 26 12:47:37 thanks Mar 26 13:00:05 mru: http://www.addedbytes.com/blog/if-php-were-british/ Mar 26 13:03:04 av500: why are you showing that to me? Mar 26 13:03:48 av500: Dear Sir, that was rather enjoyable, how charitable you are in your wisdom. Mar 26 13:06:12 jolly good Mar 26 13:10:28 mru: because you live amongst 'em brits Mar 26 13:10:38 so you can use it as a conversation starter Mar 26 13:21:24 hehe, G+ just asked me to suggest friends for Charlie Demerjian Mar 26 13:27:35 Hello, Mar 26 13:30:01 3rdstooG Mar 26 13:30:14 oh joy Mar 26 13:31:35 I have a litle problem with my BeagleBoard xM. I want to use the I2C, but I guess its disabled. I found some infos that I have to enable it at the u-boot.bin but I dont know how I can do that on my Windows PC. Does any of you have some tips for me ? Mar 26 13:35:56 get some virtualization software and install linux as a guest OS Mar 26 13:36:12 that would be a startig point Mar 26 13:37:16 ok. I have a VM. I will try to add the SD card to it. Thanks. Mar 26 13:38:26 you don't necessarily need to add the sd under the vm as long as it's already partitioned correctly Mar 26 13:39:02 password Mar 26 13:39:19 hunter2 Mar 26 13:40:09 so I have 2 partitons on it. the FAT and the (i guess) EXT3 Mar 26 13:41:54 sounds about right Mar 26 13:45:22 should not need any fiddling in u-boot to make i2c work Mar 26 13:45:40 pretty sure i2c on the expansion port is muxed as default Mar 26 13:45:48 and unter the ubuntu installation (at the board ) I see the I2C at the sys/kernel/debug. But if I try i2cdetect I get the massage "no I2c".So I guess I only have to change the boot.ini Mar 26 13:46:16 jkridner: https://github.com/beagleboard/meta-beagleboard/tree/master/contrib/bone-flash-tool Mar 26 13:46:35 Bernd: do you have /dev/i2c* ?? Mar 26 13:46:41 thanks. Mar 26 13:47:18 my autobuilder script is at http://github.com/jadonk/validation-scripts/tree/master/ec2-build/build.sh Mar 26 13:47:39 https://github.com/jadonk/validation-scripts/blob/master/ec2-build/build-angstrom.sh Mar 26 13:49:25 at /dev I have no I2C Mar 26 13:55:12 Bernd: have you tried using the demo images? Mar 26 13:55:22 Bernd: http://elinux.org/BeagleBoardUbuntu#Demo_Image Mar 26 13:55:23 XorA: but I have it at /sys/class (i2c-adapter) and the pins are in I2C mode. Mar 26 13:55:59 you should be able to do things like i2cdump -f -y 0 0x48 Mar 26 13:56:31 where 0 is the cpu bus and 0x48 is the device address Mar 26 13:56:41 will need run as root Mar 26 13:56:48 jackmitchell: I used a ubuntu Image 12.04. from the elinux side.yes Mar 26 13:57:20 Bernd: the one with the username: ubuntu and password: temppwd Mar 26 13:57:33 ubuntu-12.10-console-armhf-2013-02-16.tar.xz Mar 26 13:59:19 jackmitchell: "No size specified (using byte-data access) Error: Could not open file "/dev/i2c ..... No such file or directory Mar 26 13:59:28 Bernd: I would use the one on the page I showed you, the 12.10 version by Robert Nelson, he knows what he's doing Mar 26 13:59:46 Bernd: update to the new version and it should work# Mar 26 14:00:24 jackmitchell: Ok I will try the new version. Is there a reason why lubunto isnt used at these images? Mar 26 14:00:43 Bernd: because no one has made a version for beagleboard yet Mar 26 14:01:03 Bernd: so the issue you see is because the i2c userspace stuff is not built into your kernel, it may be a model? Mar 26 14:01:13 module? Mar 26 14:01:25 * XorA occasionally gets his letters in the right order Mar 26 14:02:00 Bernd: try modprobe i2c-dev Mar 26 14:03:26 XorA: I tried it but nothing happen Mar 26 14:03:41 Bernd: did /dev/i2c appear Mar 26 14:03:47 does lsmod show module loaded Mar 26 14:03:49 etc etc Mar 26 14:05:15
