Feb 15 08:15:19 scrts: linux is not an RTOS, hence comparisons are unfair Feb 15 08:15:57 dm8tbr: not bad, but seems to be pretty much qt-targeted Feb 15 08:18:09 ack Feb 15 08:18:11 KotH -> well yes, but I don't want to use linux, so interested in RTOSes available :) Feb 15 08:18:33 KotH: linux-rt ? Feb 15 08:20:05 * ka6sox leaves KotH with 1 thought....Asteroids are closer than you think Feb 15 08:21:03 ka6sox-away: not so much a problem here Feb 15 08:21:17 ka6sox-away: as we know from the movies, catastrophes always happen in the us Feb 15 08:21:21 ka6sox-away: hence europe is safe Feb 15 08:21:37 scrts: well... how about googling? Feb 15 08:21:54 scrts: there are tons of RTOS around, nobody knows them all... Feb 15 08:22:12 scrts: and each has a different problemclass in mind Feb 15 08:22:22 KotH -> I'm not so dumb not to google, I'm just doing some research about "what people use most" Feb 15 08:22:58 depends on the vendor that you ask. Feb 15 08:24:24 most people in here use linux, that's why you get such answers :) Feb 15 08:25:04 some also Start A Ware, but only very rarely End It. **** ENDING LOGGING AT Fri Feb 15 08:38:45 2013 **** BEGIN LOGGING AT Fri Feb 15 08:40:19 2013 Feb 15 10:25:53 http://26-26-54.hardwarebug.org/18 Feb 15 10:26:27 gm mru Feb 15 10:35:56 good moaning Feb 15 10:36:03 gm all Feb 15 10:36:49 * jackmitchell ordered his colorhug this morning, excited :D Feb 15 10:51:03 <_av500_> hug all the colors Feb 15 10:51:48 * KotH hugs _av500_ Feb 15 10:51:53 <_av500_> +1 Feb 15 10:52:03 * mru colours KotH Feb 15 10:52:06 * KotH feels like hugging a tree Feb 15 10:55:42 <_av500_> tree hugger!

Feb 15 12:21:21 <_av500_> jackmitchell: its important that you drag whole glib in for a single g_strdup Feb 15 12:22:27 I'm excited about the in kernel IPC that Greg-KH is looking at implementing and hoping that it will feature a non-glib library implementation that is sane to use Feb 15 12:23:32 but for now.... I suppose I'll try and cordon off a glib infected area Feb 15 12:27:02 jackmitchell: we went whole hog... the initial motivation was just the handy lists, strings etc Feb 15 12:27:12 i.e. not having to reinvent the wheel, again Feb 15 12:27:17 <_av500_> g-strings Feb 15 12:27:36 but the cross-platform stuff is important as well Feb 15 12:27:52 course that doesn't hold for all projects Feb 15 12:28:42 <_av500_> I once had a lib that pulled in glib for a g_strdup and a g_strcat Feb 15 12:28:54 <_av500_> I patched that out per define in the header Feb 15 12:29:00 haha Feb 15 12:29:00 <_av500_> later, we really needed glib Feb 15 12:29:07 _av500_: /facepalm Feb 15 12:29:09 <_av500_> that coworker spent quite a while on that :) Feb 15 12:30:32 <_av500_> er, not per define, but per stub function of course, so the linker picks it up :) Feb 15 12:31:48 av500 you sneaky fox Feb 15 12:31:53 the poor co-worker Feb 15 12:34:22 gm Feb 15 12:35:09 jo panto Feb 15 12:35:16 <_av500_> jo guys Feb 15 12:35:25 hi woglinde Feb 15 12:35:36 g'day panto Feb 15 12:36:23 hi jackmitchell Feb 15 12:36:36 * _av500_ waves to panto from .bg Feb 15 12:37:01 av500 hu?

Feb 15 14:32:46 that's when friday spill over into, say, tuesday Feb 15 14:33:32 isnt tuesday the day before pre-pre-friday, thus technically very similar to a friday? Feb 15 14:33:44 yes Feb 15 14:38:35 * KotH prods everyone to watch a couple of jpop videos on youtube Feb 15 14:38:42 just to make things a bit more sureal Feb 15 14:41:09 KotH: you should join g+ Feb 15 14:42:11 koth get your work done Feb 15 14:43:10 woglinde: it's friday 15:42... do you think i will get any work done when i havent the whole day? Feb 15 14:43:19 mru: so you say.... Feb 15 14:43:22 mru: i wonder if i should Feb 15 14:43:45 then you could post youtube links for us to watch Feb 15 14:44:02 and, more importantly, watch the ones we post Feb 15 14:44:12 koth I can Feb 15 14:44:30 mru: just type "jpop" into youtube :) Feb 15 14:44:46 mru: or if you want to have something not so weird: "akb48" Feb 15 14:45:08 I know what that is Feb 15 14:45:11 mru: i recommend "akb48 aitakatta" Feb 15 14:45:34 mru: though "kibou ni tsuite" is the nicer song Feb 15 14:46:11 there's more to youtube than jpop and lolcats Feb 15 14:46:23 but hardly anything more fun Feb 15 14:52:53 heres a conceptual question, if someone, wanted to interface with a stand alone ADC through SPI or the like, get data from ADC at a rate of around 100,000 to 200,000 samples per second, and spit out the data other ethernet using UDP packets, which development kit / MCU would you guys go for, or, besides being overkill, is the beagle bone okay Feb 15 14:53:49 yes Feb 15 14:54:51 if you have no prior experience with doing uC software, i'd go for the beagle for a one-off project Feb 15 14:55:11 the availability of linux as a framework simplifies a lot of things Feb 15 14:56:03 other than that.... any modern uC with clock speeds above 10MHz should be able to get the job done Feb 15 14:56:48 but then you have to add ethernet to that uC board..or get one with ethernet...arduino + shield etc. Feb 15 14:57:08 there are enough uCs out there that have an ethernet mac on chip Feb 15 14:57:13 for one-off, as KotH points out, you quickly hit price parity for ethernet plus "doing something" Feb 15 14:57:14 some even with phy included Feb 15 14:57:40 okay, well , if you decided to go for one, without an OS, which one would be considered to be the nicest to work with in terms of a friendly programmer interface? Feb 15 14:57:56 or API documentation Feb 15 14:58:02 cortex-m3 based uCs are all the rage these days Feb 15 14:58:03 arduino Feb 15 14:59:54 https://www.olimex.com/Products/ARM/ST/STM32-H103/ Feb 15 15:00:08 that one should be fast enough for simply that job Feb 15 15:00:26 and afaik there are stm32 oss frameworks around that could be used as a starting point Feb 15 15:00:34 or you can use something like nuttx Feb 15 15:00:39 nuttix* Feb 15 15:00:40 well I had a look inside both arduino dev kit, and atmel studio 6, and I would prefer atmel studio, as it has real examples such as how to properly trigger ADC's, I would not trust software triggered ADCs Feb 15 15:01:51 wow, that one looks very nicely priced Feb 15 15:02:04 olimex has a lot these kinds of boards Feb 15 15:02:09 most of them are reasonably cheap Feb 15 15:04:10 but as i said, doing uC stuff is more intricate than doing something on linux if you've never done it Feb 15 15:05:20 and often easier Feb 15 15:06:29 I have done alot of linux, I have done alot of FPGA, I have done soft uc stuff that runs on on FPGA, but that was the NIOS II processor, I havent done much main stream uc Feb 15 15:07:14 main stream uCs are nothing more than a NIOS with more preipherials Feb 15 15:07:33 and clever branding Feb 15 15:09:55 mostly not so clever branding Feb 15 15:10:50 from my experience, the better the documentation the vendor provides, the better the experience Feb 15 15:11:03 then stay away from freescale Feb 15 15:11:18 ti, st and atmel seem ok Feb 15 15:11:23 okay, Feb 15 15:11:41 with atmel, you will have undocumented silicon bugs Feb 15 15:11:56 ti seems to be quite open with the errata sheets Feb 15 15:12:17 though i have yet to see what ti does when a (small) customer finds a silicon bug Feb 15 15:12:26 no real experience with st yet Feb 15 15:21:05 apperently more arm cpus have been sold than x86 cpus Feb 15 15:21:24 more arm cpus are sold per year than x86 in total Feb 15 15:21:26 or something Feb 15 15:22:22 HappyHippo: that's nothing Feb 15 15:22:40 HappyHippo: the 6800 family is the most sold uc/up ever Feb 15 15:23:08 HappyHippo: and it's still quite widely used, although it has been deprecated for a decade or two Feb 15 15:23:42 in the 80s there has been no washing mashine sold without a HC05 or an HC11 in it Feb 15 15:24:29 these days, we have a much more diverse field Feb 15 15:26:38 thats been one of the biggest problems for me, choosing Feb 15 15:27:20 choice is an illusion Feb 15 15:28:31 as michael ende has shown us in his (iirc) "freedom" short story Feb 15 15:28:51 correction "the prison of freedom" Feb 15 15:29:05 I was about to buy some whacky japanesse thing called a Gr Sakura board (renesas), but when I looked at their online development IDE and documentation, I said no Feb 15 15:29:40 what cpu does that one use? Feb 15 15:29:50 * KotH is surprised that renesas is still alive Feb 15 15:30:03 mru, I think thats true, what I understand, is the actual arm core is intellectual property to some british people, and they just license it out to everyone Feb 15 15:30:04 they've gone arm Feb 15 15:30:20 HappyHippo: yes, that's more or less how it workss Feb 15 15:30:36 a few companies also design their own arm-compatible cpus Feb 15 15:30:49 qualcomm and marvell are the most well-known Feb 15 15:30:55 and recently apple joined those ranks Feb 15 15:31:56 HappyHippo: using something arm based isn't a bad choice these days Feb 15 15:32:24 HappyHippo: using something from one of the big names (ti,st,atmel,freescale,microchip) is also mostly safe Feb 15 15:32:42 most of those will be using arm cores Feb 15 15:32:59 well I am guessing, arm has outsold for a good reason Feb 15 15:33:14 at the moment arm has an advantage in 3rd-party tooling support Feb 15 15:33:19 think gcc and such Feb 15 15:34:00 all major vendors support arm Feb 15 15:34:45 HappyHippo: arm has become the x86 of embedded systems Feb 15 15:35:04 except without the quirky instruction set Feb 15 15:35:12 juup Feb 15 15:37:23 which reminds me... i still havent finished reading the ARM ARM... Feb 15 15:41:21 okay, well I am going to see how well I go with the beaglebone and starterware, Feb 15 15:42:25 oh.. i forgot nxp in the list above Feb 15 15:42:58 morning Feb 15 15:43:12 I had a look at nxp, the problem that made me shy away from them was their compiler prices for Keil Feb 15 15:43:19 and you'll find horror stories about _any_ vendor Feb 15 15:43:33 HappyHippo: for the arm parts? Feb 15 15:43:36 if it's arm-based you can use any compiler Feb 15 15:43:42 HappyHippo: you know, that you can use any compiler? Feb 15 15:43:58 ooops, I didnt know that one Feb 15 15:44:11 and yes, i know people who buy keil, because it is so much better than gcc... Feb 15 15:44:26 a few years ago it was Feb 15 15:44:33 gcc has improved massively Feb 15 15:44:42 mru: $customer was impressed by a shiny gui Feb 15 15:44:47 From experience, the more professionaly compiliers have better documentation Feb 15 15:45:00 mru: $customer didnt think about that a lot of stuff would need porting when he uses keil Feb 15 15:45:13 mru: $customer spend a lot of time and money on porting when he had neither Feb 15 15:45:17 KotH: for such customers there is DS-5 Feb 15 15:45:31 gcc with a shiny wrapper Feb 15 15:46:15 said customer thought he knew better than listen to us Feb 15 15:46:31 then you weren't charging him enough Feb 15 15:46:47 we are still charging him for his mistakes :) Feb 15 15:47:01 HappyHippo: btw: if you work on windows, have a look at yagarto Feb 15 15:47:09 HappyHippo: at least for arm uC stuff Feb 15 15:47:20 HappyHippo: for developing linux stuff, work on linux itself Feb 15 15:50:14 Yagarto looks good, they link to embed4fun Feb 15 15:50:21 morning prpplague Feb 15 15:50:26 greetings Feb 15 15:51:58 yo prpplague purple lord! Feb 15 15:52:26 hehe Feb 15 15:54:17 salut prpplague Feb 15 15:54:24 greetings all Feb 15 15:54:36 * prpplague is running around trying to get everything ready for ELC Feb 15 15:55:03 * mru thought there was no try Feb 15 15:56:49 morning Feb 15 15:57:16 morning central- and pacific-time trolls Feb 15 15:57:26 no mountain time? Feb 15 15:57:30 no love for mountain? Feb 15 15:57:49 Well, mranostay and prpplague specifically said hi Feb 15 15:57:56 I have plenty of love for mountain :) Feb 15 15:58:07 which are the mountain trolls? Feb 15 15:58:11 ah, hi then! Feb 15 15:58:23 morning mountain-time trolls Feb 15 15:59:27 mru: AZ is in mountain time Feb 15 15:59:35 kinda :) Feb 15 16:02:10 nowdays it's pacific time for more of the year than mountain Feb 15 16:05:11 lol Feb 15 16:06:35 alan_o: wrong - AZ is always MST. It's you daylight-savers who can't make up yer minds. Feb 15 16:06:59 and they still have only 24h per day Feb 15 16:09:37 unless you have a "Slow watch for children", then you have more hours per day. Feb 15 16:10:04 or is that less? I'm confused... Feb 15 16:10:05 DST is a scam :) Feb 15 16:10:36 promulgated by clock makers? Feb 15 16:10:54 the farmers! Feb 15 16:10:58 Here is a puzzle, why does it crash, and why does it not crash if I comment line 53? http://pastebin.ca/2314182 Feb 15 16:11:14 By crash I mean beaglebone heartbeat stop blinking Feb 15 16:11:16 can dt help here? Feb 15 16:11:19 emeb, +1, AZ has it right Feb 15 16:11:57 mdp: we don't need to save daylight. Got plenty. Feb 15 16:12:07 amen to that Feb 15 16:13:25 One thing that no DST does - it drives home how much sunrise/sunset times change through the year. Feb 15 16:16:04 time to call this friday a friday Feb 15 16:16:11 have a nice weekend boys Feb 15 16:16:20 late KotH Feb 15 16:16:22 dont troll to much... or to little, depending on your preferences Feb 15 16:16:26 s/late/later/ Feb 15 16:17:11 n7segment: a swiss is never to late, nor is he early, he arrives precisely when he means to. Feb 15 16:17:32 so dann, bis bald! Feb 15 16:17:44 KotH: or when he's meant to? Feb 15 16:18:06 highly dependent on the point of view Feb 15 16:19:09 When using GPMC, do I need to take special precautions so that linux wont use the memory region is that all configured for me already? Feb 15 16:20:07 oh well, here's something for the texans and the japanophiles alike: https://www.youtube.com/watch?v=oAmxGglMXYg Feb 15 16:24:01 emeb: yeah, its the other 49 states that have the problem :) Feb 15 16:25:40 Most people I talk to interestingly say they wish we could be on DST all year long. I don't know whether they have actually thought about it much, or if they just wish we had the long days of summer all year :) Feb 15 16:25:48 alan_o, it's an AZ thang...you wouldn't understand Feb 15 16:26:22 hehe Feb 15 16:26:57 alan_o, soon as that sun goes over the horizon, it's time to BBQ and sit outside ;) Feb 15 16:27:33 * mdp wants a prize for all of his elinux edits today Feb 15 16:31:51 right, I think I'm just about done too. gdbus-codegen can sod off - how anyone can bare to integrate that is beyond me Feb 15 16:32:54 another week, another method; maybe a websocket based ipc Feb 15 16:33:02 mdp you have to wait for elc Feb 15 16:33:32 I'm waiting until the prize is a rigol dso Feb 15 16:36:21 rigol ? get yourself one of the x3000 series from agilent :-) Feb 15 16:36:25 mdp: Feb 15 16:36:42 hehe Feb 15 16:37:02 my employer doesn't provide those kind of tools ;) Feb 15 16:37:20 I'm going to keep my wishlist sane, like a PCIe analyzer Feb 15 16:37:45 eh Feb 15 16:37:47 *he Feb 15 16:37:57 <- can't type Feb 15 16:39:14 mdp: :-( Feb 15 16:39:21 mdp: your employer isn't the nicest one around :-p Feb 15 16:39:35 your isn't so great either ;) Feb 15 16:39:36 mdp: oh yeah... a sexy lecroy PCIe analyzer ?? Feb 15 16:40:06 that would be great ;) Feb 15 16:40:10 nice employers? those exist? Feb 15 16:40:39 mranostay: I hear EA used to be a cool place to hang out Feb 15 16:40:43 :-p Feb 15 16:57:37 Electronic Arts?!? Feb 15 16:57:44 If I change the mask at line 53 from 0xFFFF to 0xFFFE it does not crash, huh? Any silicon erratas regarding the gpmc? http://pastebin.ca/2314182 Feb 15 17:06:58 Anyone with a beaglebone and 5 minutes to spare to run that program and tell me if it crashes too Feb 15 17:07:23 No doing anything fancy just writing all valid values to gpmc 10 million times Feb 15 17:07:40 crahes the beaglebone in less that 15 seconds Feb 15 17:09:27 CareBear\: http://elinux.org/BeagleBone_6502_RemoteProc_cape Feb 15 17:12:30 mdp : oh sweet! Feb 15 17:14:14 pru assembler (c) 2005 !! Feb 15 17:14:39 hehe Feb 15 17:14:51 I guess I should link over to the slideware and video to be complete Feb 15 17:15:32 I think this is fine Feb 15 17:15:38 as long as the exact steps are there Feb 15 17:15:49 ok, now I'm nervous Feb 15 17:15:58 there's never enough exact steps ;) Feb 15 17:16:34 exact steps please Feb 15 17:16:58 do you have a youtube of it? Feb 15 17:17:26 I should sit in the dark with an led blinking like most people do their youtube videos Feb 15 17:17:37 mdp : now that, people would understand Feb 15 17:17:49 you would be right up there with the cat videos Feb 15 17:18:25 mdp: no idea, it just seems current meme is people demanding videos of people typing commands into consoles as just a list of commands doesnt do it for them! Feb 15 17:18:34 indeed, the internet is for po^H^Hcats Feb 15 17:18:43 see how many how to root you XXX videos there is on youtube now! Feb 15 17:19:26 XorA: I can't figure that one out either. I got an search for exact steps on some thing (like a good little googler does) and I get those same videos...not sure why they expect me to wait 10 minutes while they typo crap Feb 15 17:19:47 it's multimedia Feb 15 17:20:34 that reminds me..it seems instagram interest died off pretty quick Feb 15 17:21:03 urgh... no dosfstools in the Angstrom 2012.12 feeds. :( Feb 15 17:22:39 mdp: what is the EA felipebalbi talks about? Feb 15 17:22:55 mranostay, ours Feb 15 17:22:58 RIP Feb 15 17:26:59 FYI.... https://learn.sparkfun.com/tour Feb 15 17:27:33 CareBear\: come to think of it, isn't that what I did at ELCE? typing a bunch of commands live that I could have just listed? ;) Feb 15 17:43:37 jkridner, are you around? Feb 15 17:43:44 yup Feb 15 17:44:00 jkridner, have you seen enyojs? Feb 15 17:44:22 http://enyojs.com/ Feb 15 17:44:25 yes Feb 15 17:44:43 some guys got it running under nodejs Feb 15 17:45:03 do you know about node-webkit as well? Feb 15 17:45:11 yes Feb 15 17:45:23 but webkit is just the rendering engine Feb 15 17:45:36 this is more like a app/gui framework Feb 15 17:45:56 right... but the idea is that you can make remote apps and desktop apps with the same code. Feb 15 17:46:18 for example, this would be great to add a gui to some kind of flashing tool and getting-started tool for BeagleBone. Feb 15 17:46:42 I started to write a node-webkit app for getting started with BeagleBone, but I got hung-up on socket.io not working under node-webkit. Feb 15 17:46:59 jkridner, I see Feb 15 17:47:16 what I was more interested in was for a local GUI Feb 15 17:47:29 I didn't want to start calling the node methods directly within the browser, so I want to get socket.io to work across platforms---to provide same experience and source in local app or over the web. Feb 15 17:47:34 full blown desktop is overkill for 99.999% of the bone's use cases Feb 15 17:47:43 yeah, enyo looks pretty good for making GUIs. Feb 15 17:48:03 I don't necessarily care what GUI framework is used, but I do care about seeing it done under a browser. Feb 15 17:48:09 and the same GUI works over the browser too Feb 15 17:48:16 exactly. Feb 15 17:50:30 panto, for my 'Bone projects I am using enyo.js and node.js Feb 15 17:50:40 works well Feb 15 17:50:41 ka6sox-away, cool Feb 15 17:50:54 got something you can share? Feb 15 17:51:08 not yet, next week after SCaLE Feb 15 17:51:44 ka6sox, just fine with me Feb 15 17:51:51 next week is a void anyway :) Feb 15 17:52:11 no kiding Feb 15 17:52:23 6 days of Conferences Feb 15 17:52:41 6 days is nothing Feb 15 17:53:04 in a row? Feb 15 17:54:39 in anything Feb 15 17:55:44 jkridner, good email re: patchset trees Feb 15 17:56:25 ka6sox: hopefully we can get some collaboration with the Xenomai guys and more. Feb 15 18:01:53 jkridner, I hope so. Feb 15 18:03:21 panto: beer, women, and talks! well two of those :P Feb 15 18:03:48 * mranostay suspects someone updated java on this machine and didn't tell him Feb 15 18:03:57 jsabeaudry: swag..something about the gpmc implementation's lack of byte decoding? I vaguely remember something about limitations there..could be entirely wrong Feb 15 18:04:01 * mranostay adjusts tin foil hat Feb 15 18:04:51 mranostay: so if I skip the talks...? Feb 15 18:05:37 i can skip every talk except mine Feb 15 18:05:54 same here Feb 15 18:06:20 that goes double for me Feb 15 18:06:50 I'm skipping mine Feb 15 18:06:58 sounds boring anyway Feb 15 18:07:12 instead of talking to the chair we will just stare at it? Feb 15 18:13:25 mranostay: I'm skipping the whole event. beat that! :( Feb 15 18:13:45 but then you miss all the women Feb 15 18:15:14 "Yeah, well... I'm gonna go build my own theme park, with blackjack and hookers. In fact, forget the park!" Feb 15 18:19:51 dm8tbr: you suck Feb 15 18:20:16 now that's not a very nice thing to say Feb 15 18:20:17 you well you can get a few of those around the area we are in SF :) Feb 15 18:20:19 my budget does, since it disappeared into a black hole... Feb 15 18:21:08 what, you got married? Feb 15 18:21:38 if we aren't invited to a troll wedding i'm going to be mad Feb 15 18:22:42 it's all about the groupies Feb 15 18:22:48 mranostay knows Feb 15 18:23:42 mru: no, the company 'reorganized' and essentially I fell through the grid. Has anybody seen my stapler? It's a red swingline, they don't make them anymore... Feb 15 18:26:43 they actually didn't make those before the film came out Feb 15 18:26:54 I know :) Feb 15 18:27:11 they started making them later though due to popular demand Feb 15 18:27:20 I think the prop was spray-painted? Feb 15 18:27:37 yeah, they just painted one for the set Feb 15 18:30:53 mdp, byte decoding? what do you mean by that? Feb 15 18:48:48 mranostay : I'll take beer and women Feb 15 18:59:56 Trivial program crashes the beaglebone 10/10 @ 720 MHz but crashes 0/10 @ 600 MHz: http://pastebin.ca/2314233 Feb 15 19:00:49 how are you powering it?

Feb 15 19:05:26 I'll attach one, give me a sec Feb 15 19:08:58 jsabeaudry: I thought gpmc didn't have byte level decoding..just halfword on am335x Feb 15 19:09:09 or maybe that was in some particular mode Feb 15 19:09:39 just not sure, but your change in mask made me think of that Feb 15 19:09:46 mru: http://pastebin.ca/2314239 Feb 15 19:10:07 mdp: looks like halfword to me Feb 15 19:12:19 maybe I read wrong..but did he say he changed the mast from 0xffff->0xfffe and it worked? Feb 15 19:12:30 ugh nm Feb 15 19:12:56 can I go on holiday now?

Feb 15 19:16:32 gpmc I see Feb 15 19:16:36 Russ, I mapped gpmc there Feb 15 19:19:39 Possible that the gpmc is not exactly stable @ 720 MHz ? Feb 15 19:21:05 doubtful, people would be pretty upset if nand didn't work at all Feb 15 19:21:12 at that OPP Feb 15 19:23:09 I'm running in NOR mode Feb 15 19:23:13 (the GPMC) Feb 15 19:24:20 NOR also gets tested Feb 15 19:24:34 it's on the EVM Feb 15 19:24:56 well, on the "GP daughtercard" Feb 15 19:25:03 What is the typical write cycle time for these memories? Feb 15 19:26:16 i.e. Could it be that my write cycle time is too long and that a second write happens before the first one completed? Feb 15 19:26:38 Hmmm, nvm that couldnt explain the mask thing Feb 15 19:28:04 16uS/word Feb 15 19:30:00 Oh not a problem I'm at 120ns/word Feb 15 19:32:31 I reproed the problem both on A3 and A6 Feb 15 19:34:48 It repros with or without the gpmc end point attached (in my case a fpga) Feb 15 19:44:57 anybody want to tell me real quick where to write to the pinctrl sysfs to change the mux mode? Feb 15 19:45:15 jkridner, not supported Feb 15 19:45:17 does the answer also have to be accurate? Feb 15 19:45:27 that's nuts. Feb 15 19:45:48 * jkridner kicks pinctrl repeatedly until dead. Feb 15 19:46:05 ok, I'm ready to go back to 3.2. Linux has only gotten worse. ;-) Feb 15 19:46:17 pinctrl will rise again Feb 15 19:46:24 why not 2.6.32 while at it? Feb 15 19:46:33 perhaps. :) Feb 15 19:46:58 some of my beagles are still running 2.6.32 Feb 15 19:47:04 so, I guess I need to make syscalls to change the mux mode? Feb 15 19:47:10 jkridner, if we quit making new processors and laying off people, there'd be time to work on these things ;) Feb 15 19:47:56 well, new processors add more value than changing interfaces, but I agree with your point. Feb 15 19:49:26 I expect CCO will handle it now Feb 15 19:49:37 I wonder what happens when I try to call pin_config_set when running a pre-3.7 kernel. Guess I'll find out. Feb 15 19:50:44 nice how the function call doesn't even abstract the meaning of the configuration value. Feb 15 19:50:57 any why shouldn't I just poke the registers directly again? Feb 15 19:51:22 poke them from where? Feb 15 19:51:40 er, userspace. Feb 15 19:51:45 can't Feb 15 19:52:01 they're privileged, need to do it from a kernel module Feb 15 19:52:01 quick little kernel patch could fix that. Feb 15 19:52:12 yep Feb 15 19:52:35 or you could lead by example and do a not-so-quick little kernel patch and put it upstream Feb 15 19:52:45 just sayin' Feb 15 19:52:57 if it was quick enough for me, I would. Feb 15 19:53:20 I'm busy enough trying to show dummies like me how to use what is there, let alone change it. Feb 15 19:53:36 personally, I would ask CCO if they can have their paid beagle developers look at this Feb 15 19:53:37 jkridner, you're trying to subvert the idea behind pinctrl Feb 15 19:53:49 I'll start with a hello_pinctrl.c and go from there. Feb 15 19:53:51 you shouldn't change mux settings manually Feb 15 19:54:10 it's supposed to be done via a device Feb 15 19:54:29 which it will set those pinctrl settings when it's activated Feb 15 19:54:29 Can someone please repro my 600MHz/720MHz GPMC issue, here is a script to config the gpmc http://pastebin.ca/2314242 and here is the trivial c code: http://pastebin.ca/2314245 Feb 15 19:54:36 panto: I wasn't serious about poking the registers, but it is reasonable for apps to directly access devices, such as GPIO. Feb 15 19:54:49 You only need a beaglebone, gcc and devmem2 Feb 15 19:54:55 panto is about to tell you that you need to wait for dynamic overlays and capemgr upstream Feb 15 19:55:03 jkridner, heh Feb 15 19:55:14 but I have those downstream now to play with. Feb 15 19:55:16 yeah, it's trivial to do it with !capebus Feb 15 19:55:36 jkridner: so why don't you use those then? Feb 15 19:56:07 great. I'll go back to trying to get the modified 'dtc' compiled natively on Bone. Feb 15 19:56:14 the problem with banging at the pinmux registers directly is that by themselves they are meaningless Feb 15 19:56:30 seems like the .dtbo loading is a bit ugly though. Feb 15 19:56:42 jkridner, just devmem the pinmux config registers Feb 15 19:56:49 beholder Feb 15 19:57:16 compared to "echo 7 > mux_mode" Feb 15 19:57:17 jkridner, it's how firmware is loaded in linux Feb 15 19:57:35 let me get 'dtc' compiled and come back with an opinion. Feb 15 19:57:36 jkridner, that command is super dangerous Feb 15 19:58:15 you're affecting hardware configuration without tracking who owns what Feb 15 19:58:19 jkridner, if you ever sit back and really think about all these blogs showing how to whack pinmuxes...it's not easy Feb 15 19:58:26 it's confusing to everybody Feb 15 19:59:11 The 'dtc' I have compiled from upstream doesn't understand fragments. I'm going to compile the patched version now. Feb 15 19:59:31 what panto's trying to point out is that if you accept the dt/pinctrl part, then it's much easier to follow grouping and ownership of those pin resources Feb 15 19:59:59 I accept that the interface is whacky Feb 15 20:00:00 jkridner, that's indeed, important Feb 15 20:00:24 yeah, I get that, but 'echo 38 > /sys/class/gpio/export' should know to perform the pinmux allocation! Feb 15 20:00:25 but it's an interface for !TI parts too Feb 15 20:00:38 panto, "pinctrl totally whacky???" ;) Feb 15 20:01:02 yet '/sys/kernel/debug/pinctrl/44e10800.pinmux/pins' shows that the pin is still in mux mode 1. Feb 15 20:01:19 which I don't know how it ever got into mux mode 1 to begin with. Feb 15 20:01:19 jkridner, what you need is a way to interface gpio-lib to pinmux Feb 15 20:01:50 but that is something that the omap gpio lib driver should do Feb 15 20:01:58 agreed, gpio functions should know about pinctrl. Feb 15 20:02:33 jkridner, it's not so simple though Feb 15 20:02:36 so, perhaps I should just jump straight to fixing that? Feb 15 20:03:01 jkridner, if you manage not to break all other omaps in the process sure :) Feb 15 20:03:10 yeah, even if the GPIO is allocated, it might be routed out at multiple pins. :( Feb 15 20:03:21 jkridner, right Feb 15 20:03:37 so what the real problem is, is a problem of kernel infrastructure Feb 15 20:03:39 plus, the platform information mapping GPIOs to pins isn't currently part of the kernel as far as I know. Feb 15 20:03:50 coming up with generic interfaces is not easy Feb 15 20:04:34 so that's why it's easier for people to start hacking around until they get their part working (but in a non-portable way) Feb 15 20:05:02 yeah, yeah, we've all been there. Feb 15 20:05:16 FWIW even the gpiolib interface with gpio numbers is bogus IMO Feb 15 20:05:35 the gpio number is a totally meaningless quantity Feb 15 20:05:55 but I guess they're trying to fix it now Feb 15 20:06:05 panto, yes, I wondered if you missed that Feb 15 20:06:16 panto: for some reason, the patched dtc gives me an error when I try to compile... Feb 15 20:06:24 dtc-parser.tab.h seems to be renamed dtc-parser.tab.h_shipped Feb 15 20:06:25 it's a long known problem...not exactly broken just IYO Feb 15 20:06:31 is it safe to just rename it back? Feb 15 20:07:53 jkridner, it's how they ship it for inkernel use Feb 15 20:08:02 what sources are you trying to compile? Feb 15 20:08:17 kernel/scripts/dtc Feb 15 20:08:54 one thing you said, confused me panto, you are aware that the gpio subsystem does support pinctrl as a part of request()...it's just the gpio-omap doesn't support that feature Feb 15 20:09:10 right Feb 15 20:09:28 it's just that TI doesn't care yet ;) Feb 15 20:09:42 or somebody Feb 15 20:09:45 it's a don't care for TI Feb 15 20:10:00 at least tegra/samsung care ;) Feb 15 20:10:34 jkridner, I'm curious why it doesn't compile Feb 15 20:10:52 are you just trying to compile dtc from within the kernel sources? Feb 15 20:10:56 looks like I might be invoking make from the wrong directory or something... Feb 15 20:11:03 yeah Feb 15 20:11:05 looks like the Makefile isn't top-level. Feb 15 20:11:11 it's not Feb 15 20:11:12 yes Feb 15 20:11:38 just copy the kernel sources and do 'make dtbs' Feb 15 20:11:40 * jkridner tries 'make scripts' Feb 15 20:11:51 it should compile the dtc as part of that Feb 15 20:11:54 k Feb 15 20:12:12 the standalone dtc tool should be better to use Feb 15 20:20:06 k, dtc compiled now Feb 15 20:21:15 hmmm lots of command line arguments and include files seem to be required to make a dummy gpio-pinctrl test. Feb 15 20:22:11 panto: converting jkridner to the light? Feb 15 20:25:03 panto: do you pass *all* of the .dts files to dtc at the same time to make the dtbo? Feb 15 20:25:34 no Feb 15 20:25:39 nm, I missed th e-! Feb 15 20:25:40 just the fragment Feb 15 20:25:43 er, -@ Feb 15 20:25:58 right that's the switch that enables it Feb 15 20:26:29 'dtc -O dtb -o x.dtbo -b 0 -@ cape-boneblack-hdmi-00A0.dts' worked for me, now I'll try to make one that is just my GPIO pin. Feb 15 20:27:42 ok, I have to take off now Feb 15 20:27:49 have a kickass weekend everybody Feb 15 20:28:18 hmm, where are those to be found? Feb 15 20:30:06 no weekend for me for another few hours Feb 15 20:31:06 * prpplague thinks Crofton is already drinking Feb 15 20:31:49 can't blame him Feb 15 20:32:30 there is liquor in the freezer Feb 15 20:33:15 this wine bottle isn't quite empty... Feb 15 20:33:23 and there's always the scotch Feb 15 20:33:27 so, to mux pins from within the kernel, do I just make a pinmux_config struct and call setup_pin_mux? Feb 15 20:34:02 or should i just set them manually with memory writes? Feb 15 20:36:06 the clean way on 3.2 is indeed with the struct in the board file Feb 15 20:37:18 ok, thanks jsabeaudry! Feb 15 20:39:15 * jkridner just realizes this means I can instantiate gpio-keys, not just GPIO. very nice. Feb 15 20:49:36 mrnaostay, there is no light on mainline Feb 15 20:49:43 mranostay, even Feb 15 20:49:56 mdp: someone broke your tab key? Feb 15 20:49:57 Is it possible to skip the EEPROM called for on a cape and just init the bone pins manually. The EEPROM route seems like it is more trouble than it is worth unless you're using a lot of different capes. Feb 15 20:50:20 Guest23197: trouble? Feb 15 20:50:24 mru, I was trying to prove I could do it the old fashioned way...and failed Feb 15 20:50:31 I need to use the tab crutch Feb 15 20:50:41 Should just be a bunch of SFRs to set up, no? Feb 15 20:50:42 you can do a prototype without it Feb 15 20:50:43 mdp: my dad's old typewriter had a tab key... Feb 15 20:50:54 ;) Feb 15 20:51:00 what is a typewriter? Feb 15 20:51:46 * mdp gets one off the storage rack for a photo shoot Feb 15 20:52:28 https://lh4.googleusercontent.com/-qDPtIMdvAV8/ULtl9uBJYPI/AAAAAAAAC4w/X3C0Bx9FFeU/s0/ Feb 15 20:52:47 everything is on the internets! Feb 15 20:53:05 hmmm Feb 15 20:53:08 that gives me an idea Feb 15 20:53:23 you know the alphabet books with a page for each letter and a picture to go with it? Feb 15 20:53:30 We need one for errno Feb 15 20:53:30 sure Feb 15 20:53:34 +1 Feb 15 20:53:40 Russ: but they're all E Feb 15 20:54:12 -ETOOMANY Feb 15 20:54:36 -EWRONGSTEPS Feb 15 20:56:05 well he didn't wait long enough. Feb 15 20:56:26 ETIMEDOUT Feb 15 20:56:37 mranostay : a typewriter is the reason that you have a qwerty keyboard layout Feb 15 20:57:32 and that's why i refuse to use it Feb 15 20:57:38 * mru senses retelling of LIES in the offing Feb 15 20:57:57 aoeui4ever! Feb 15 20:58:19 wouldn't it be "',.pyf"? Feb 15 20:58:25 the truth is qwerty was designed to minimise jamming Feb 15 20:58:37 had nothing to do with typing speed Feb 15 20:58:58 good old typewriters Feb 15 20:58:59 mru : minimise jamming while typing the word "typewriter" with one hand Feb 15 20:59:12 it has everything to do with making your fingers move further for common character sequences Feb 15 20:59:18 Russ: LIES Feb 15 20:59:23 is it possible to manually configure the headers on a bone and not use the eeprom setup that is suggested in the SRM? Feb 15 20:59:41 mru, it's why qwerty doesn't put t and h together Feb 15 20:59:43 beagle357 : the eeprom is not a suggestion Feb 15 20:59:50 beagle357 : it's a specification. Feb 15 20:59:53 Russ: so? Feb 15 21:00:10 beagle357 : if you believe that specifications are suggestions then people will consider you ignorant Feb 15 21:00:22 Russ, mru doesn't see a reason that key proximity should be related to typing speed. Feb 15 21:00:26 adjacent type arms link to vertically adjacent keys Feb 15 21:00:34 so thee is no way to configure he pins via SFRs? seems weird. Feb 15 21:00:44 i.e. 1qaz2wsx Feb 15 21:01:07 beagle357 : what is possible is documented. you will obviously not get any help to implement something that does *not* follow the specification Feb 15 21:01:21 if you scan the keys in that order, you'll find few sequences that occur naturally in english words Feb 15 21:01:44 noobish_: proximity has little to do with speed Feb 15 21:01:51 i know you think that. Feb 15 21:01:54 if you know how to type properly Feb 15 21:02:00 which clearly you do not Feb 15 21:02:02 you type with your fingers flailing about Feb 15 21:02:30 you seem to know me very well Feb 15 21:02:38 i assume you use qwerty. Feb 15 21:02:39 okay well then thanks for critiquing my language at least. Feb 15 21:02:46 noobish_: so? Feb 15 21:03:00 that's where the "flailing about" comes from. Feb 15 21:03:08 fuck you Feb 15 21:03:19 watch someone type quickly with dvorak and you'll understand the "flailing" of qwerty. :P Feb 15 21:03:20 bloody hipsters Feb 15 21:03:22 ~.~ Feb 15 21:03:23 hahah Feb 15 21:04:01 if you type with two fingers, perhaps Feb 15 22:01:32 Hmmmm Feb 15 22:16:25 * mranostay scrolls up Feb 15 22:17:11 scrolling, scrolling, scrolling... Feb 15 22:17:56 mru: testy mood today? Feb 15 22:18:08 mranostay, thats not testy Feb 15 22:18:35 hmm, there's a film on netflix titled '54' Feb 15 22:19:10 only 15-rated though Feb 15 22:19:11 * mru skips Feb 15 22:19:37 as in Studio 54 in NYC Feb 15 22:20:19 http://uk.imdb.com/title/tt0120577/ Feb 15 22:21:03 wrong, its paris. Feb 15 22:21:06 my bad Feb 15 22:22:37 so, what is the value of the the internal pull-up/down resistor on the gpio? Feb 15 22:22:51 sorry, I lost all interest in helping you Feb 15 22:22:51 i can't seem to find it. in the dc electrical specs, i see leakage for when pullup/down is enabled Feb 15 22:23:10 is this the pull-up/down current? Feb 15 22:23:24 cool story mru. Feb 15 22:29:45 hello trolls Feb 15 22:32:13 hrmm...doesn't look like the pull up/down impedance is in the datasheet Feb 15 22:32:28 unless they're labelling it as leakage...which would be not surprisingly silly. Feb 15 22:32:42 after all, they probably don't use dvorak Feb 15 22:35:36 lol, ok fine. I'm sorry for saying you had flailing fingers, mru. please take this apology as a token of my wanting you to stop whining. Feb 15 22:40:02 i'm not very good at conflict resolution :( Feb 15 22:43:27 hmm... I don't think my firmware files are loading. Feb 15 22:43:47 when I echo "gpio-pinctrl-test" > /sys/devices/bone_capemgr.8/slots, I get -sh: echo: write error: No such file or directory Feb 15 22:44:29 if I 'cat /sys/devices/bone_capemgr.8/slots', 6: ff:P-O-- Override Board Name,00A0,Override Manuf,gpio-pinctrl-tes shows up for every time I issue the echo Feb 15 22:46:04 cd to /sys/devices/bone_capemgr.8 Feb 15 22:46:06 see if slots is there Feb 15 22:46:53 yes, that is how I cat it.

Feb 16 00:34:48 YuckTo Feb 16 00:34:54 if that doesn't get his attention Feb 16 00:35:02 mranostay: you have to admit though, tizen has more potential Feb 16 00:35:24 pick your poison... you'll still be dead :P Feb 16 00:36:10 holaaaa Feb 16 00:36:29 SGX works with 32bpp these days, right?

Feb 16 03:20:36 er isn't that just pwm? :) Feb 16 03:20:39 it is Feb 16 03:20:57 but ecap can also function as a counter, which I call 'ecap in' Feb 16 03:21:31 which is the useful part :) Feb 16 03:21:43 how fast of a clock have people tried ecap out? Feb 16 03:22:19 I've only used ehrpwm so far Feb 16 03:22:46 koen-: you know how long a GPO pulse is from the PRU? i can't find it in the TRM i know i've seen it Feb 16 03:22:57 i would guess ~1 clock cycle Feb 16 03:24:16 yes, in theory ~1 clock cycle Feb 16 03:24:19 koen-: how fast of a clock have you used it with? Feb 16 03:24:31 but I don't know how a 100MHz signal looks when it comes out of the header Feb 16 03:24:45 depends on what you are doing ;) Feb 16 03:25:00 ds2: 100k driving a fet with a cap, so that is practically DC :) Feb 16 03:25:18 koen-: for what i am doing, that is desireable Feb 16 03:25:29 doing an audio out w/o using a CODEC Feb 16 03:35:19 prpplague: hey purple dude Feb 16 03:35:27 mranostay: greetings Feb 16 03:37:14 * mranostay sips a Stella Feb 16 03:39:00 prpplague: weird thing with interviews now they ask for your github page :) Feb 16 03:39:15 mranostay: yea i heard some people say that was happening Feb 16 03:39:34 mranostay: they always ask about for my G+ spock albums url Feb 16 03:40:41 prpplague: mine is weird it is a combo of python, c, poky recipes, Eagle PCB library mods, and presentations :) Feb 16 03:40:50 * prpplague looks to see what the name of the beer he is drinking Feb 16 03:41:16 franziskaner weissbier Feb 16 03:42:46 +10 Feb 16 03:43:11 prpplague: _av500_ would be proud Feb 16 03:51:01 everyone shout Yocto at davest on the count of three Feb 16 03:55:05 e Feb 16 03:55:07 3 Feb 16 03:55:10 2 Feb 16 04:31:44 i'm trying to use omap_mux_init_signal (from mux.c) from my kernel module, but when I try to install my module, I get a "WARNING: "omap_mux_init_signal" undefined" error Feb 16 04:32:07 is there a kernel module i need to load first? Feb 16 04:34:34 and is it an exported function? Feb 16 04:35:38 checking Feb 16 04:36:13 ugh...doesn't look like it. Feb 16 04:36:39 so, what does the sysfs stuff use!? Feb 16 04:36:54 are they calling their own, redundant, functions or something? Feb 16 04:37:01 err..kernel debug stuff i suppose. Feb 16 04:37:49 er yeah Feb 16 04:38:23 unless are you using DT Feb 16 04:38:36 no. just stock angstrom. Feb 16 04:39:57 any idea what the sysfs stuff uses? Feb 16 04:40:57 ugh, if they're not going to use a standard interface, why should i!? memory writes it is! :D Feb 16 04:43:21 guess i'll dig through the code and see what functions they're using, and hope they're exported (hahahah!) Feb 16 04:45:51 err wait, looks like ioremap *is* the only way, cause, why would they export that shit? who would want to mux a pin in the kernel? Feb 16 04:46:52 guess i'm happy about it. will take me 2 minutes rather than 2 hours digging through undocumented code. Feb 16 05:00:20 newberish, there's only room for one of us Feb 16 05:01:03 haha Feb 16 05:01:15 i'll interrupt everyone Feb 16 05:01:29 hahah, pru humor!!! Feb 16 05:01:45 i'm lonely :( Feb 16 05:02:17 I think you are on the wrong channel Feb 16 05:03:37 * mranostay notes that and goes to drink Feb 16 05:04:09 Hmmm Feb 16 05:04:47 Question: I started messing around with Arduino and found several good books that bring you through the learning process along with examples in each section. Is there such a book for the beagle bone? Feb 16 05:05:06 no. lots of tutorials online now though Feb 16 05:05:21 using the javascript library and stuff Feb 16 05:05:41 and, there are a few python libraries too if you're controlling gpio Feb 16 05:05:59 (at several mhz rather than the ludicrously slow sysfs stupidity) Feb 16 05:06:58 I just recently started learning javacript @ codecademy.com, I am a complete newb to linux. How should I start the learning process? Feb 16 05:07:00 i think you'll find it very easy actually, especially if you're just doing slow things. Feb 16 05:07:45 if you're fast, there are many "getting started with linux" type tutorials Feb 16 05:07:58 or, if you're slow, you can check out some of the online video courses for introduction to linux Feb 16 05:08:17 Would you please provide a link that you recommend for a slow person? Feb 16 05:08:26 although, if you just want to get started programming the beaglebone, there's not all THAT much linux involved Feb 16 05:08:45 except normal directory traversing and whatnot, which isn't any different that windows command prompt. Feb 16 05:09:03 sure, one sec Feb 16 05:09:49 http://bit.ly/14XGplH Feb 16 05:10:49 here's an example of bonescript: http://www.gigamegablog.com/2012/01/05/beaglebone-coding-101-blinking-an-led Feb 16 05:11:58 and, when i say "especially if you're just doing slow things" i mean, not wiggling wires too quickly. Feb 16 05:12:39 or, at least in strange ways (uart, i2c, and stuff is built in and can wiggle plenty fast) Feb 16 05:16:24 Ok, so the initial setup shows plugging the beaglebone into your network and getting an IP via DHCP. Can you not "console" in via the usb? Feb 16 05:16:42 you can. Feb 16 05:16:51 after you install the drivers, it'll show up as a virtual comm port Feb 16 05:17:00 it'll also show up as a mass storage device Feb 16 05:17:26 then, you can "console" in and disable that, and enable "ethernet over usb" to give it network access.. Feb 16 05:17:56 but, you can start programming on it from the web server and ide that comes with it. Feb 16 05:18:45 i think it's covered in the introduction slideshow, "beaglebone 101" or whatever. Feb 16 05:19:14 the links in the slideshow work, so you can go to the ide right from the slideshow. Feb 16 05:21:04 damn it...the current DT status is a bigger mess then right after a hurricane Feb 16 05:21:53 I see, thank you PRU Feb 16 05:22:49 don't expect much help in here btw...most of these guys are jerk faces that are doing really complicated stuff. Feb 16 05:22:55 :D Feb 16 05:23:52 :p Feb 16 05:54:06 is it ok to give iounmap a null pointer? Feb 16 05:57:55 doesn't look like it's ok. Feb 16 06:01:22 how many red box turtles does it take to fill a 40g barrel? Feb 16 06:01:32 nm, got it. Feb 16 06:01:42 forty gallon or 40Grams? Feb 16 06:02:07 40grains? Feb 16 06:18:38 if its 40graines I want to stay out of the way Feb 16 06:18:49 s/graines/grains/ Feb 16 06:19:50 have a good weekend everyone!!! Feb 16 06:23:32 mranostay: you still awake? Feb 16 06:24:05 a better question is whether sober. Feb 16 06:31:23 ka6sox: cute Feb 16 06:32:21 mrpackethead: sup? Feb 16 06:32:46 someone alleged your blood alcohol level Feb 16 06:33:49 not 0.00 i'll admit :) Feb 16 06:34:50 i was just hunting in the TRM for the pulse width Feb 16 06:34:52 but cant' find it Feb 16 06:35:15 yeah i know i've seen it before not 100% in was in the TRM now Feb 16 06:35:45 the PRU chapter is one paragraph Feb 16 06:35:50 is there another document? Feb 16 06:38:56 pru reference guide Feb 16 06:39:22 although i can't find it in there even Feb 16 06:39:49 i know i've seen the actual pulse length number in some doc.. Feb 16 06:39:54 I thought I saw it in the AM18XX PRU guide Feb 16 06:40:00 ah! Feb 16 06:41:46 ka6sox: i'm interested to know why the PRU sends these pules rather than setting a state Feb 16 06:46:20 the AM335x in the current form is sure F'ed Feb 16 06:47:03 ds2, I'm not sure I'd say that... Feb 16 06:47:07 its "different" Feb 16 06:47:14 ka6sox: everywhere i turn, there is an errata Feb 16 06:47:27 apparently the RTC is a power guzzler due to an errata Feb 16 06:47:35 and it is basically broken Feb 16 06:48:03 there is a RTC? Feb 16 06:48:08 I need a GPS anyways to syncronize things... Feb 16 06:48:16 EVM? Feb 16 06:48:21 so I just keep disciplining it. Feb 16 06:48:28 it is in the SoC itself Feb 16 06:48:37 but it requires cooperation of the PMIC Feb 16 06:48:44 a RTC an help the GPS lock quicker Feb 16 06:49:47 I just leave the GPS running Feb 16 06:49:55 I need it to keep things in Sync. Feb 16 06:50:07 u got lots power :D Feb 16 06:50:26 I need at least 25W for the transmitter! Feb 16 06:50:35 some are 25kW Feb 16 06:53:24 power is not an issue Feb 16 06:53:47 with a 25KW xmitter nearby, I can parasite power it with a diode ;) Feb 16 06:54:27 if there is that much energy in the building..I dont' want to be there. Feb 16 06:54:35 heheh Feb 16 06:55:09 Sign I saw on a fence in one place: DANGER: Do not Enter! Your family line will END here... Feb 16 06:55:52 do you also carry flourescent tubes to the sites? Feb 16 06:56:10 only on Halloween, and Blackface too... Feb 16 06:56:58 to scare the beegeebers out of mischeif makers. Feb 16 06:57:44 oh... but it sounds like the places you goto, the tubes would just glow Feb 16 06:59:10 not till you you touch the towers... Feb 16 06:59:16 then they glow in the field Feb 16 07:00:51 oh Feb 16 07:03:18 I'm sure several of the taggers had to change their shorts(which was pretty funny since they had low rider shorts on) Feb 16 07:04:27 hahah Feb 16 07:06:15 dang...62C on that i7 now... Feb 16 07:06:37 there is an interstate I7 through the desert? Feb 16 07:07:03 no, I've been running a simulator on my i7 at my office Feb 16 07:07:22 I7 is a north south interstate, right? Feb 16 07:07:31 if there was one it would be Feb 16 07:07:50 I5, I15 are the 2 furthest west Feb 16 07:07:59 I8 runs down along the mexican border Feb 16 07:08:32 8hrs, and only 128,497 clock cycles simulated. Feb 16 07:08:42 trying to figure out what this I7 is you speak of... Feb 16 07:09:24 i7-3770K...intel 3rd generation processor. Feb 16 07:09:31 Ohhhhhh x86 crap Feb 16 07:09:33 blah Feb 16 07:09:43 its simulating a Virtex5 Feb 16 07:09:48 (and not very well) Feb 16 07:09:59 why not just get a virtex5 dev board? :D Feb 16 07:10:15 thats running too. Feb 16 07:10:48 ah... so your entire office is at 62C now? ;) Feb 16 07:11:11 the V5 rarely gets above 48C Feb 16 07:12:42 what is the virtex5 being configured to do? Feb 16 07:14:31 push 4TB files out serially Feb 16 12:27:04 morning trolls Feb 16 12:28:48 trololololo Feb 16 12:36:55 gm mru Feb 16 13:44:36 * koen- yawms Feb 16 13:45:55 gm koen Feb 16 13:48:11 hey woglinde Feb 16 13:50:15 and till later again Feb 16 13:50:31 basketball game is waiting for me as ref Feb 16 16:39:26 morning Feb 16 16:39:37 good moaning to you too Feb 16 17:22:24 mru: when you fly?

I have a beagleboard-xm, would it work to use expansion header pins UART2_TX, UART2_RX, and GND? Feb 16 18:18:51 alan_o: I know, just putting the barcelona shirt in context Feb 16 18:21:28 hehe, those things are _bright_. I've worn mine a couple times. Feb 16 18:22:49 * dm8tbr likes his Feb 16 18:23:07 I actually have two of those as they were giving them away at the end Feb 16 18:40:46 dm8tbr: score? Feb 16 18:41:37 mranostay: sorry? Feb 16 18:43:26 dm8tbr: two shirts Feb 16 18:45:05 they had lots of them left over on the last day when the whole yocto thing was going on and they were tearing down the place Feb 16 18:52:32 yocto will have that effect Feb 16 19:13:03 hi everybody Feb 16 19:14:47 i have beagleboard xM i boot linux oon this board but i can't get ethernet Feb 16 19:14:52 can i have some help Feb 16 19:15:25 which distro are you using? Feb 16 19:16:16 i use a simple linux kernel 3.6.0-rc7-12547-gc0a2203 Feb 16 19:16:52 no userspace? Feb 16 19:17:00 yes Feb 16 19:17:21 i want just to set up the ethernet interface Feb 16 19:18:03 well just build in the right kernel module then Feb 16 19:19:20 right... Feb 16 19:19:59 i do so Feb 16 19:20:08 re Feb 16 19:20:18 but i think that i have some problem with my smsc chip Feb 16 19:20:56 i will rebuild the kernel Feb 16 19:21:32 smsc makes always trouble same with musb Feb 16 19:21:50 let's simplify that: usb is trouble Feb 16 19:28:31 hehe yes and ethernet via usb ist trouble ^2 Feb 16 19:33:17 woglinde: USB in general Feb 16 19:35:25 *sigh* I know that Feb 16 19:36:09 but put something you have to poll on USB and *faceplam* :) Feb 16 19:38:11 hey all Feb 16 20:22:29 mranostay: usb itself is polled Feb 16 20:23:18 mru: yes i understand Feb 16 20:27:58 btw, anyone know what kind of display connections they're likely to offer at elc? Feb 16 20:28:05 for presentations Feb 16 20:28:51 mru: VGA likely Feb 16 20:29:09 it was in one of the emails Feb 16 20:29:13 vga only iirc Feb 16 20:29:21 I only saw one saying bring your own laptop Feb 16 20:29:27 and vga stinks Feb 16 20:30:11 tsk. I'd expect them to have DVI/HDMI nowadays Feb 16 20:30:35 I had expected dvi/hdmi years ago Feb 16 20:31:09 my dvi -> vga passive dongle is always a big hit at conferences Feb 16 20:31:17 it struck me as a good idea to make sure the external outputs on the laptop are working before I get there Feb 16 20:31:36 my laptop has hdmi and vga Feb 16 20:32:06 hdmi appears to be working properly Feb 16 20:35:01 now your problem is to find a VGA cable and a screen with such input? ;) Feb 16 20:35:13 I can't get the displayport -> vga dongle working under linux Feb 16 20:35:19 dp -> hdmi work Feb 16 20:35:22 dp -> dvi works Feb 16 20:35:26 dm8tbr: I have both of those somewhere around Feb 16 20:35:26 builtin hdmi works Feb 16 20:35:42 mac display port? Feb 16 20:35:47 I even used one not long ago Feb 16 20:35:58 so I'll either reboot into osx or borrow a laptop with vga Feb 16 20:36:06 has no analog signal that I'm aware of Feb 16 20:36:17 thurbad: hence the dongle Feb 16 20:36:23 it's an active one Feb 16 20:36:27 ah Feb 16 20:36:29 just like the dvi and hdmi ones Feb 16 20:36:52 dp has too many options Feb 16 20:37:09 or I could get prpplague to build me a hdmi -> vga active board Feb 16 20:37:17 now that we are coworkers and all Feb 16 20:37:32 I thought that wasn't supposed to be official Feb 16 20:37:57 #beagle, where secrets go to die Feb 16 20:43:52 don't worry i won't tell Feb 16 20:44:01 i can be bribed with beer at ELC :P Feb 16 20:44:02 yeah, right Feb 16 20:44:25 http://26-26-54.hardwarebug.org/140 Feb 16 20:45:56 mmm..

Feb 16 20:46:13 http://26-26-54.hardwarebug.org/93 Feb 16 21:05:40 uhhh koen spoiled it Feb 16 21:06:47 spoiler alert Feb 16 21:08:02 hah Feb 16 21:10:06 hi joel Feb 16 21:10:34 howdy mr joel_ !! Feb 16 21:12:43 hey guys Feb 16 21:13:11 I think they will have HDMI on this one. I confirmed with them couple of days back, just no display port so you've to get an adapter. Feb 16 21:14:40 i'll rent mine for $50 a hour :P Feb 16 21:15:36 :P Feb 16 21:15:41 or borrow koens' Feb 16 21:15:56 Guess everybody busy making slides? Feb 16 21:16:59 done Feb 16 21:17:13 mranostay: ah k. share them somewhere? Feb 16 21:17:26 mine's at: http://elinux.org/Fit-boot#Presentation Feb 16 21:17:47 joel_: excellent, saves me the trouble of testing vga Feb 16 21:17:52 weren't we supposed to send the slides in 2 days ago? Feb 16 21:18:06 we were Feb 16 21:18:15 heh Feb 16 21:18:21 but that's just first cut Feb 16 21:18:26 I sent them in yesterday :) Feb 16 21:18:36 incomplete of course Feb 16 21:18:38 I assume it's ok to make changes after submitting them Feb 16 21:18:45 * koen- complied to the letter, not the spirit Feb 16 21:18:49 completion will happen on the plane ;) Feb 16 21:19:19 I'm not presenting until thursday Feb 16 21:19:26 so completion can happen night before Feb 16 21:19:26 joel_: you missed the cake thing yesterday at TI Feb 16 21:19:28 after the bar closes Feb 16 21:19:41 koen-: was it a lie? Feb 16 21:19:44 koen-: I know :'( I had a conflicting meeting Feb 16 21:19:46 it was delicious Feb 16 21:19:48 will see y'all anyway at elc Feb 16 21:20:19 no raspberry filling, though Feb 16 21:20:23 heh Feb 16 21:21:13 joel_: http://elinux.org/ELC_2013_Presentations#Presenters Feb 16 21:21:13 too many 0's on the cake. one more 0 and you'd need to get 2 cakes. maybe in next yr, million beagles :-P Feb 16 21:22:24 mranostay: ah yes, thanks Feb 16 21:22:46 mmmm beagle pi wouldn't sell here Feb 16 21:23:37 heh Feb 16 21:23:42 that wiki is funny Feb 16 21:23:50 it swaps presenter and title a lot Feb 16 21:24:23 joel_: your time slot sucks btw :) Feb 16 21:24:32 what is with three TIers in the same one? Feb 16 21:24:51 can only troll one of you guys.. no fair Feb 16 21:25:02 think outside the box Feb 16 21:25:11 troll 1 talk, get escorted out Feb 16 21:25:14 mranostay: hehe. since we work together, we can always present to each other without being at elc ;) . its more efficient Feb 16 21:25:18 troll talk 2, get escorted out Feb 16 21:25:20 etc Feb 16 21:26:15 er the tables are effed up Feb 16 21:26:44 mranostay: it's a wiki... Feb 16 21:26:57 mranostay: that's what I said earlier :) Feb 16 21:27:04 maybe we should bitbake a wiki with gpio Feb 16 21:28:40 bitbang wiki? Feb 16 21:28:53 *trying to troll* Feb 16 21:33:52 fixed Feb 16 21:34:06 must be a wiki OCD Feb 16 21:40:40 joel_: one plus of an early talk i can troll back those that troll :P Feb 16 21:42:21 trolls trolls troll troll trolls Feb 16 21:42:47 that's how it works, right? Feb 16 21:59:24 mranostay: looks good. +1 on the colors too. mine's just bland red and white. red to blend well with the TI logo Feb 16 22:04:45 does anyone know if there are any half decent USB --> Ethernet Converters that work with the beaglebon. Feb 16 22:05:56 onboard ethernet no good? Feb 16 22:12:37 need two Feb 16 22:12:40 ports Feb 16 22:12:41 the bottleneck is not in the usb dongle Feb 16 22:12:45 the onboard one is just fine Feb 16 22:12:46 but in the MUSB controller Feb 16 22:13:27 i'd have to look to see if the second Ethernetport can be accessed Feb 16 22:13:40 via the headers.. but my guess is no. Feb 16 22:14:05 no, you're missing 2 rgmii signals Feb 16 22:15:07 how much of a bottle neck is the MUSB? Feb 16 22:15:22 it doesn't do DMA with the current software Feb 16 22:16:09 could you acehive 20Mb/s? Feb 16 22:16:29 mrpackethead lol Feb 16 22:16:35 thats probably not Feb 16 22:17:07 what could you acehive? Feb 16 22:17:28 test yourself Feb 16 22:17:33 i'm going to Feb 16 22:17:34 depends on many factors Feb 16 22:17:34 koen-: has musb ever worked? :) Feb 16 22:17:48 but you guys have plenty of good pointers Feb 16 22:17:49 or this a edma issue? Feb 16 22:18:17 koen-: the hdmi sniffer can be used to a vga adapter Feb 16 22:18:23 mranostay: never worked, and on am335x it's using CPPI, not EDMA Feb 16 22:18:49 mrpackethead just buy a usb<->ethernet adapter with a chipset mentioned in kernel Feb 16 22:18:56 does not cost much Feb 16 22:19:03 5 euros I paid on ebay Feb 16 22:19:27 what sort of throughput could i expect? Feb 16 22:19:34 *sigh* Feb 16 22:19:53 you have to test Feb 16 22:19:54 what sort of throughput do you get woglinde Feb 16 22:20:16 I did not make any tests on my ac100 Feb 16 22:22:06 Google is fun on this topic.. theres a lot of Ethernet over USB of course Feb 16 22:22:52 musb w/ cppi dma worked once upon a time. then again "worked" has many definitions Feb 16 22:23:47 mrpackethead: most usb-eth adapters use smsc or asix chips Feb 16 22:23:55 both have good drivers Feb 16 22:24:05 as good as any usb thing, that is Feb 16 22:25:37 I just use g_ether :x Feb 16 22:25:59 that works if you're connecting it to a usb host Feb 16 22:26:03 True. Feb 16 22:26:04 shadyman I do not think he wants connection via usb cable Feb 16 22:26:08 ah Feb 16 22:26:13 didn't read the backlog :) Feb 16 22:26:18 haha Feb 16 22:26:30 a lot of the really cheap ones seems to use davicom chips Feb 16 22:26:55 idealy, need an ethernet connection Feb 16 22:27:27 the beagle needs to sit between two broadcast domains Feb 16 22:27:35 there is another possible trick Feb 16 22:27:41 that i could do Feb 16 22:27:44 but its a bit guly Feb 16 22:28:20 i could connect a VLAN trunk to the beagle Feb 16 22:28:27 with a managed switch Feb 16 22:28:38 that probably would work. Feb 16 23:30:48 I have a beagleboard-xm that doesn't work, is there any way to understand what part is broken? Feb 16 23:31:09 did the magic smoke escape? Feb 16 23:31:30 there were no smoke Feb 16 23:31:45 what did you do that made it stop working? Feb 16 23:31:46 it might be because of gpio Feb 16 23:32:58 I was using gpio that one gpio outputs 3.3 V and another gpio get that signal via a relay Feb 16 23:33:17 now I cannot get video output and no serial console output Feb 16 23:33:37 beagle has 1.8V i/o Feb 16 23:34:06 right Feb 16 23:34:11 I confused it with beaglebone Feb 16 23:34:14 so 3.3V will fry it Feb 16 23:34:23 yes, bone has 3.3V Feb 16 23:34:46 I connected a gpio to another gpio basically Feb 16 23:34:54 it should be 1.8 V Feb 16 23:36:55 when I power the board, I see that D5 and D14 leds are constant green Feb 16 23:37:36 is there any way to understand what is the real problem? Feb 16 23:40:14 * mranostay trolls in Feb 16 23:40:35 you fried the chip Feb 16 23:40:49 oh when the punks, go trolling in.... Feb 16 23:41:11 angs: so you hooked up 3.3V gpio to what? Feb 16 23:42:23 hmm, this reminds me of my overvoltage protection for the beagle: http://hardwarebug.org/files/beagle_overvoltage.jpg Feb 16 23:42:36 should be good for at least 5kV Feb 16 23:43:06 mranostay: actually it is not 3.3V, it is 1.8V because I connected a gpio to a relay, then connected the relay output to another gpio to read. basically it was like connecting a gpio (output) to another gpio (input) Feb 16 23:43:28 mru: nice Feb 16 23:44:42 * mranostay suspects angs is not telling us a step Feb 16 23:44:52 I'm certain of it Feb 16 23:45:03 relays have more connections than that Feb 16 23:45:28 a typical relay has 4 terminals Feb 16 23:46:37 mru: three at least Feb 16 23:46:58 3 is not typical Feb 16 23:47:22 one purpose of a relay is to isolate the sides electrically Feb 16 23:47:24 yes i know Feb 16 23:47:33 it was a sensor's alarm relay output that has only NC and C terminals here is the sensor that I used http://resource.boschsecurity.com/documents/Installation_Guide_all_2627312395.pdf Feb 16 23:48:29 it was just cutting the signal when there is no motion and relay let the current flow when there is a motion. Feb 16 23:48:54 maybe I did something wrong on the gpio configuration, I could not understand what was wrong with it Feb 16 23:49:26 can it be used the board just for decoration now? Feb 16 23:49:58 would there be any use of it Feb 16 23:52:32 you could sharpen the edges and throw it at intruders Feb 16 23:54:21 encase it in epoxy and use it as a beer coaster Feb 16 23:55:20 mru: that is a use for the r-pi Feb 16 23:55:42 I'm afraid it would spoil the taste of the beer Feb 17 01:41:35 mru: how you do use your coasters exactly? :) Feb 17 01:42:49 to bludgeon intruders of course **** ENDING LOGGING AT Sun Feb 17 02:59:57 2013
