**** BEGIN LOGGING AT Wed May 01 02:59:58 2013 May 01 03:04:49 Are there instructions for putting ubuntu on the internal storage of the beaglebone black? May 01 03:05:14 you want ExactSteps? May 01 03:06:19 if its something as simple as dd if=ubuntu.img of=/dev/mmcblk0p1 or something May 01 03:06:22 i would just need the device name May 01 03:06:31 if its more complicated then probably May 01 03:23:16 Any figure out the BBBLack io mux without using the bone script -- using C/C++ ??? May 01 03:23:24 how to get a uart4 working ? May 01 03:26:13 question I've yet to find an answer to ssh login to beagle bone credentals , I can get a password prompt tried: root user with (blank) and root and toor May 01 03:27:45 none of them worked May 01 03:27:58 on the beagle bone black May 01 03:39:26 i just did ssh root@192.168.7.2 from my laptop and then used password 'root' May 01 03:39:58 haven't done much past that point, poked around, ran 'top', had to run to dinner May 01 04:17:37 what sorcery makes the usb0 networking interface work in angstrom, and is it something that I could get working in another distro? May 01 04:18:33 enable usb networking in the kernel and setup the device? May 01 04:19:44 hm... lemme find it May 01 04:21:27 usb networking seems to be all enabled in the kernel I built... now to figure out which module it is :P May 01 04:21:50 is it a module? May 01 04:22:08 usually that I would build in unless you *want* to insmod it every time. May 01 04:22:14 sigh... why do people insist on the module crap May 01 04:22:30 ds2, kernel size is important for some devices May 01 04:22:44 modules still take up space May 01 04:22:49 and modules don't XIP May 01 04:22:56 true to both May 01 04:23:10 however...for testing its better than crashing or OOPSing May 01 04:23:12 I just took defaults to get *something* built, and yes most of it is modules May 01 04:23:23 but I don't know what hardware the usb network device is May 01 04:23:24 ssi, what distro? May 01 04:23:35 modules caues more problems then they solve May 01 04:23:36 I'm looking at the angstrom system at the moment May 01 04:23:39 and I see the usb0 device May 01 04:23:45 /dev/usbX is the usual name May 01 04:23:47 ya, that one May 01 04:23:50 in dmesg, but there's no hints as to which hardware or module it is May 01 04:24:15 ifconfig usb0 up 192.168.7.2 May 01 04:24:34 there is usually no /dev/usbX May 01 04:24:39 unless you got some wacky patches May 01 04:24:44 it's up in angstrom... lemme reboot into the debian image and see if it shows up in dmesg May 01 04:24:48 if you dont' get an ioctl error...then you ar golden May 01 04:25:36 before you go and reboot May 01 04:25:39 just try to bring it up May 01 04:25:47 it was already up on that one May 01 04:25:49 even without assigning an IP. May 01 04:25:50 and I've already rebooted :) May 01 04:25:54 oaky May 01 04:25:55 just chuck this silly concept of distros May 01 04:25:56 oaky May 01 04:26:03 build your own with exactly what you want May 01 04:26:27 ds2, if you have 100GB of free space and a machien with 4GB of RAM and a lot of time. May 01 04:26:48 it doesn't take 100GB of free space May 01 04:27:07 I do it with much less on a much smaller machine (1GB ram) May 01 04:27:35 linking some X things can be dicey with that :p May 01 04:27:47 I don't have issues May 01 04:27:47 unless you have switched to Gold. May 01 04:27:59 I have done Angstrom builds, Android builds, etc on that box May 01 04:28:05 and it is only a dual cored atom May 01 04:28:17 Hurt Me Baby! May 01 04:28:25 its important that everyone roll their own distros and kernels that way problems can not be reproduced! May 01 04:28:44 hence, I dispute all those claims May 01 04:28:44 this will keep the platform exclusive to us 1337 h4x0rz! May 01 04:28:54 Joe SixPack can't do that... May 01 04:28:54 nothing hard about it May 01 04:28:57 distros are a waste of time May 01 04:29:05 he can't even boot things right May 01 04:29:28 then he should use an appliance May 01 04:29:48 which uses a *distro* for its packages :P May 01 04:30:02 if computers become easy to use then anybody could learn computers and we would have job competition May 01 04:30:09 that can not be allowed to happen May 01 04:30:28 * crashovrd obfuscates some more C code May 01 04:30:52 doesn't have to May 01 04:31:01 no need to have packages May 01 04:31:44 IRC: arguing over nothing since 1988 :D May 01 04:35:13 the problems with using Linux thesedays is almost all distro sourced May 01 04:35:22 like the messed up windowing systems they try to push on people May 01 04:36:37 windowing systems (window manager) or Desktop GUI? (gnome3, unity, kde plasma) May 01 04:37:00 aha May 01 04:37:02 g_multi May 01 04:37:26 eewwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww May 01 04:38:05 why not g_android May 01 04:40:16 doesn't load though May 01 04:40:21 gadget: no file given for LUN0 May 01 04:40:31 g_multi musb-hdrc.0.auto: failed to start g_multi: -22 May 01 04:41:26 he hehe he he he May 01 04:47:53 prpplague: dude!

May 01 05:02:56 it could work May 01 05:03:01 ENOERROR May 01 05:03:03 :S May 01 05:39:50 quick noob question: I am following the tutorial that came onboard my beagleboard black. I have configured two led circuits to send blinks to. May 01 05:40:09 One of them is on P8_17 and it blinks fine. The other on P8_21. It does not blink May 01 05:40:28 what is the difference between these two. they are both set to be "out" and they are both listed as digital io May 01 05:43:31 DOH May 01 05:43:44 lemme test totally different ports. may be conflicting with HDMI driver for BBBlack May 01 05:45:16 well.. thats embarassing. carry on! May 01 05:47:07 glad we could help May 01 06:00:49 hi guys please help in on beaglebone webcam interface May 01 06:01:23 i have connected the web cam n download n extracted mjpgstremer on /home/root/ May 01 06:01:39 n then typed make May 01 06:01:50 anyone ther?

May 01 10:18:14 dm8tbr, Reall? Because there arent a lot of people who know that. May 01 10:18:19 really* May 01 10:20:00 * dm8tbr has seen more l10n and i18n issues than he wanted in his life already May 01 10:26:06 Hi, I'm interested to participate for Gsoc on the project which sugeested to build a librery files use with Wiring and Arduino IDE May 01 10:26:25 Im now making my proposal to submit May 01 10:27:05 also have a look at other possible ideas May 01 10:27:08 i need know your idea about the project May 01 10:29:11 whether it will usefull to the beagleBoard user May 01 10:29:28 can someone help me on this May 01 10:31:07 I did and choose the one i mentioned May 01 10:45:50 Can I readout IO pins easy when from userland ? May 01 10:51:21 -EPARSE May 01 10:51:43 ? May 01 10:52:09 what do you mean? is it possible to read gpio input values from userspace? May 01 10:52:11 Qantourisc: yes, you can easily read pins from userland May 01 10:52:13 the answer is yes May 01 10:52:16 next! May 01 10:53:19 sweet, so if i need ethernet an os, i pick beagle and not a µC :) May 01 10:54:31 Qantourisc: that has no correlation with your previous question, yes the beaglebone has ethernet, yet it can run an OS and yes it can read IO pins May 01 10:54:40 but so can a iC May 01 10:54:46 s/iC/uC May 01 10:54:56 jackmitchell: yea but the ethernet stack are often so-and-so May 01 10:55:26 maybe, but realtime performance on the beaglebone is so-and-so, depends what you want to do with it really May 01 10:56:18 jackmitchell: when we are talking "realtime" what time contrains are we talking about ? May 01 10:57:05 what time contraints do you need? If you need to read an IO pin once every 10ns without fail, then BeagleBone with Linux OS is not the correct choice May 01 10:58:03 jackmitchell: not every 10ns, to be fair, i Don't know the required speed yet :) May 01 10:58:25 it's a RS485 bus, but don't know it's speed yet May 01 10:58:26 going from knowledge of using a basic uC with a simple RTOS, to using a full blown Linux OS with a complex SoC is something that needs to be researched and fully understood May 01 11:01:22 the BeagleBone is a good choice, for a general purpose dev board, but you need to nail down your requirements and decide if Linux is the right choice, especially if you are used to using a traditional uC, it's a whole different kettle of fish May 01 11:04:11 jackmitchell: the pru can read an input every 10ns, but not a whole lot more May 01 11:39:48 Been thinking, no time contrains, and I could just use an UART May 01 13:02:09 hi May 01 13:02:14 lo May 01 13:02:55 i was just wondering how is that possible that beaglebone black has better specs but cheaper than the normal one? thanks May 01 13:05:13 jo mru May 01 13:05:47 write an email to ti May 01 13:06:02 velvet: I'd guess a very careful redesign that allowed to lower costs. Maybe also the chip is cheaper from TI for some reason? May 01 13:06:27 and less margins across the chain May 01 13:09:04 alright thanks, then obv im getting the black :) May 01 13:12:55 dm8tbr, nothing to do with the am3359 May 01 13:13:06 ok May 01 13:13:22 the board redesign..if you look at the components, it's less of the expensive stuff May 01 13:13:36 starting with the ftdi May 01 13:22:19 take a careful look at the missing connectors too May 01 13:36:34 moaning, channel May 01 13:36:42 hi bradfa May 01 13:36:46 hi bradfa May 01 13:36:51 howdy, folks May 01 13:36:55 hi panto May 01 13:37:01 hi woglinde May 01 13:37:07 hi jkridner|work May 01 13:37:12 he jkridner May 01 13:37:34 we're friendly today, eh? :) May 01 13:37:41 yes? May 01 13:37:44 * bradfa scans the horizon for trolls May 01 13:37:57 * bradfa should be looking under bridges May 01 13:41:21 hi panto, woglinde. May 01 13:42:52 jkridner how many participants we have now for gsoc? May 01 13:44:39 I've seen 13 applications from students. May 01 13:44:58 oh nice May 01 13:45:07 how many are realistic? May 01 14:00:21 jkridner|work: Hi, need some feedback about my proposal https://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/hustcalm/1, thx May 01 14:04:20 I want to make a happy land for novices to try beaglebone. May 01 14:04:25 _av500_, from the TI feed "We are continuing to spread the multicore love through the month of May!" May 01 14:04:36 McLovin May 01 14:04:54 remember to use protection May 01 14:04:57 * panto backs away May 01 14:05:14 shower your lover in dsp evms May 01 14:05:26 won't that hurt? May 01 14:05:32 those things are normally huge May 01 14:05:55 Anybody know how to acces the BBB UARTS from C ? May 01 14:06:00 I'm just following exactsteps May 01 14:06:33 ClemsonTim80, yes May 01 14:06:45 ClemsonTim80, http://stackoverflow.com/questions/10242648/programming-linux-serial-port-ttys0 May 01 14:06:46 like normal tty devices May 01 14:06:56 s/ttyS0/ttyO0/ or whatever May 01 14:07:09 first hit on google..standard *nix/linux May 01 14:08:01 Serial was working fine on BB using /dev/ttyO1 but that doesn't exist for BBB May 01 14:08:40 Hey! I contacted customer service for farnell, they say that if you order now you can have your BBB by May 11. May 01 14:09:18 For everyone in the UK. :-) May 01 14:09:22 disabled by default in the 3.8 dts May 01 14:09:45 Hey mdp :-) May 01 14:10:15 yes, I'm back to reviewing that May 01 14:11:38 Is there any way to add UART support from C or do I have to go back to original BB ? May 01 14:12:26 ClemsonTim80, of course May 01 14:12:59 firmware/capes/cape-bone-tester-00A0.dts contains an example of enabling UART1 May 01 14:13:20 panto, are there prebuilt dtbos for the uarts that can just be loaded? May 01 14:13:21 panto, or does he need to compile one? May 01 14:13:45 mdp, one has to compile one for now May 01 14:13:55 yeah, that's missing May 01 14:14:25 it's something like 10 lines of DT May 01 14:15:16 panto & mdp - Could somebody post something in the Forums addressing this ? I don't think I will be the last to ask about it. May 01 14:16:18 panto, it just made me think that it would be nice to have those prebuilt in a future image May 01 14:16:18 something for koen ;) May 01 14:19:09 lol May 01 14:19:13 forum again May 01 14:19:14 ClemsonTim80, quick and dirty May 01 14:19:14 http://hastebin.com/renoyeqive.avrasm May 01 14:19:23 it should work May 01 14:19:33 mdp, you're right May 01 14:19:50 panto, truth! May 01 14:19:53 :) May 01 14:20:12 it's just going to be a common thing..this made me consider that May 01 14:20:13 uart1 is the ftdi? May 01 14:20:29 no ftdi May 01 14:20:31 on the black May 01 14:20:35 ftdi was sent away May 01 14:20:48 uart1 which is brought on the headers May 01 14:21:03 along with the others May 01 14:21:13 err, BB-BONE-TESTER is obviously wrong May 01 14:21:54 http://hastebin.com/vihepemugi.avrasm May 01 14:22:05 panto - Thanks - I will take a look at the link right now. I was using UART_1, 2 and 4 on BB Classic. Will this apply to all ? May 01 14:22:32 ClemsonTim80, you have to modify pinmuxing for each May 01 14:22:39 but the idea is exactly the same May 01 14:23:44 ieehks May 01 14:23:45 target = <&uart2>;/* really uart1 */ May 01 14:23:59 *facepalm* May 01 14:24:28 does anyone have an idea what OMAP_ALTELECTRICALSEL does? May 01 14:25:28 Sounds dangerous. May 01 14:25:28 I would read it alternative electric selection May 01 14:25:42 woglinde, yes, facepalm May 01 14:26:00 blame the omap-isms that are in am33xx May 01 14:26:18 panto inconsisty at counting? May 01 14:26:23 morning May 01 14:26:27 one starts at 0 one at 1? May 01 14:26:29 omap has fortan numbering May 01 14:26:31 HO KA6SOX May 01 14:26:34 ka6sox: afternoon May 01 14:26:36 args caps May 01 14:26:48 not only that hwmod blows up if you move to base 0 numbering May 01 14:26:50 MORNING WOGLINDE! :) May 01 14:26:54 hi ka6sox May 01 14:27:13 I think they've fixed it in 3.9, but I haven't checked May 01 14:27:22 panto, you have explained why we need to remove it as a dep of the PRU stuff. May 01 14:27:33 morning panto May 01 14:27:46 ka6sox, I wish it was as easy May 01 14:27:51 *this May 01 14:28:07 I'm sure there are more "gotchas" May 01 14:31:18 panto, hehe, VH picked up my old patch to fix the fortran numbering and included other stuff that had since been dropped in with fortran numbering May 01 14:31:47 panto, dunno what happened to it though May 01 14:32:01 I have no idea May 01 14:32:34 TI has got to start testing DT booting for 3.9 to shake out the bugs May 01 14:32:38 panto, it would be nice if the beagleboard kernel folks would fix the numbering in that tree to avoid the inevitable support issues May 01 14:33:03 think that Friday is going to be enough :) May 01 14:33:13 mdp, we have to May 01 14:33:18 I'm not sure who works on that stuff upstream now May 01 14:33:19 it's all terribly confusing May 01 14:33:48 found it - pull up type for am33xx... May 01 14:36:24 panto: when you have the overlay, and compile it with dtc, how do you apply it? May 01 14:36:30 tsquar3d, have you dropped the idea of 3d visualization of the collected data? May 01 14:36:38 mdp: Nope. May 01 14:36:45 cmicali, you put the dtbo file in /lib/firmware May 01 14:36:58 mdp: it is a bonus. May 01 14:37:02 echo PART-NUMBER >/sys/devices/bone_capemgr*/slots May 01 14:37:06 and it should load May 01 14:37:15 ah you have to use bone_capemgr? May 01 14:37:19 yes May 01 14:37:20 panto: where PART-NUMBER is <= 16 characters in length May 01 14:37:25 right May 01 14:37:30 tsquar3d, have you looked at sigrok at all wrt data collection and analysis? May 01 14:37:46 panto: is there something keeping us from having them a bit longer (like 32)? May 01 14:37:51 you can use capemaps to use a more descriptive name May 01 14:37:59 panto: or write your own kernel driver that implements the overlay kernel API May 01 14:37:59 mdp: Yeah, I have... that might be a good way to go... although I am not especially familliar with it. May 01 14:38:00 alan_o, see above May 01 14:38:10 tsquar3d, you might consider looking at some creative uses of that as the data collection and analysis engine May 01 14:38:23 the PART-NUMBER 16 char limit comes from the eeprom format May 01 14:38:26 panto: but capemaps require modifying the main bone dtsi, which 3rd party cape vendors won't want to have to do May 01 14:38:33 oh May 01 14:38:43 alan_o, format limit :) May 01 14:38:53 hmm, so the name I'm using I can't stick into my eeprom anyway... May 01 14:39:04 tsquar3d, the framework is very flexible even though it originally focused on logic analyzer signal collection..it's expanded to a wide variety of data collection May 01 14:39:10 mdp: Honestly, I am up for trying different mothods -- we just need to see which is best... so I may be evaluating a few different approaches sigrok, js, etc. May 01 14:39:49 tsquar3d, if you found that interesting and tuned you proposal that direction, I think there could be clear and obvious impact on the community. May 01 14:40:14 mdp: towards visualization? May 01 14:40:20 Or towards using sigrok? May 01 14:40:36 one reason is that if you are developing support for some additional sensors collection paths from the kernel into sigrok...expanding that...it helps a wide variety of use cases May 01 14:40:54 mdp: Okay... well, I am certainly open to that. May 01 14:41:00 rather than building a new data acquisition and analysis engine project May 01 14:41:10 let me put it this way May 01 14:41:27 when I start a new project based on FOSS, I try not to write any code at all May 01 14:41:39 I want to reuse copy whatever I can...I'm very lazy May 01 14:41:48 mdp: Not lazy, smart. May 01 14:42:25 mdp: 3 virtues of a great programmer: laziness, inpatience and hubris. May 01 14:42:36 *impatience May 01 14:42:41 ... but not spelling. May 01 14:42:42 :-) May 01 14:42:47 so, my thought is that with sigrok's filter framework, you have the framework to do some analysis...chaining processing filters May 01 14:43:14 I'm not a sigrok expert so I don't know when you will run into limitations on streaming data through it May 01 14:43:21 mdp: Okay... well, would you be (or do you know of someone) who would be willing to mentor me on that? May 01 14:43:27 but biot may have some advice in that area May 01 14:44:00 it would be good to get his input on the sigrok part..if this is sane May 01 14:44:48 mdp: Well -- you are not the first to suggest sigrok to me, so I think that must be the way forward. May 01 14:44:50 since he's in .eu, he's probably around atm, let's see if he awakens May 01 14:45:25 tsquar3d, we've talked about it on this channel a few times in that past...in the scope of collecting data from iio and processing in sigrok May 01 14:45:26 I'm in .uk, so yeah... he should be awake. May 01 14:45:26 lol May 01 14:45:31 I think it's a common though May 01 14:45:36 thought May 01 14:46:12 sorry for being too slow May 01 14:46:30 mdp: Well, let's do it! I am good with the data analysis and viz part per my physics background and research interests... May 01 14:46:45 I need some Beagle bevavior advice May 01 14:47:04 Guest77585 guest throw some wood May 01 14:47:10 beagle brings back May 01 14:47:29 my beagle is almost 7 is is now very aggressive with food May 01 14:47:55 bit my nephew when going for his food this morning May 01 14:48:06 any ideas as to what might have brought this on? May 01 14:48:13 mdp: I will look further into sigrok this afternoon -- and update my proposal. I also need a mentor and someone else from the community that can write 1-3 paragraphs on how this would benefit the community. May 01 14:48:13 Yeah, wrong channel Guest77585, sorry May 01 14:48:13 try a new power supply May 01 14:48:24 Guest77585, sorry, this is not a Beagle (the canine) channel May 01 14:48:29 sorry May 01 14:48:29 Sorry, I only have a chihuahua. May 01 14:48:36 Guest77585, no problem ;) May 01 14:49:00 hm I thought it was a joke May 01 14:49:02 hm hm May 01 14:49:05 haha May 01 14:49:12 I was gonna say, who comes to IRC for advice on dogs? May 01 14:49:14 woglinde, we get them occasionally. May 01 14:49:22 Food agression is not a joke. May 01 14:49:37 I almost gave advice too ;) I have one that is very aggressive with food...bit her sister to take that bowl of food one time ;) May 01 14:49:37 that came afterwards May 01 14:49:55 mdp: Same here... my chihuahua will bite your hand off... May 01 14:50:15 The trick is to get them to realize that YOU are the provider of their food.... May 01 14:50:20 tsquar3d, two front the same litter...total opposites..sometimes have to separate them at feeding time May 01 14:50:48 anyway... :) May 01 14:50:56 mdp: Let me guess, one is a pig and the other one is more docile? May 01 14:51:51 so i am new here, just got a beagle board... was curious what proposal you have going May 01 14:51:51 Alright... I will have another look at sigrok and update my proposal. Still need the mentor and the second to back me up. May 01 14:54:39 smith_: Not marriage... got that out of the way already. May 01 14:55:09 .... yeah, I am not funny. May 01 14:55:16 shit, spent 5 minutes on here and found something cool I didn't know about before: sigrok May 01 14:56:23 marriage is not a joke tsquad May 01 14:56:53 Well -- if you do not subscribe to social norms and you believe that love transcends a piece of paper, it is. May 01 14:57:36 My wife and I got married so that she could get a dependant visa while we study in the UK. May 01 14:58:13 what do you study May 01 14:58:18 Computing. May 01 14:58:29 thats a big field May 01 14:58:36 Yep. May 01 14:58:48 That's the degree. May 01 14:59:05 focus? May 01 14:59:19 Specifically, I am doing an MPhil in Computing with a research emphasis on educational games for physis. May 01 14:59:22 physics* May 01 14:59:26 I hate it. :-) May 01 14:59:41 we all do while were here May 01 15:00:06 i've met a few computer folks lately interested in edu games May 01 15:00:11 I game design stuff is fun... the "educational" part is death. May 01 15:00:25 GBL is bullsh*t. May 01 15:00:34 well, you guys have made huge improvements in fields like bio that were stuck with problems May 01 15:01:20 tsquar3d, this is a family channel... May 01 15:01:21 any frameworks you recommend? pygame something else? May 01 15:01:33 ka6sox: That's why I put the asterix in. :-) May 01 15:03:48 Wait.... where does it say this is a family channel? May 01 15:06:16 mdp: Hmm... sigrock looks like a great idea.. May 01 15:06:21 sigrok* May 01 15:07:24 oh yeah, and I recall now that some LAs working in streaming fashion..and that's supported May 01 15:08:17 have you considered what type of data you would collect as the test vehicle for this? May 01 15:08:25 mdp: This would actually be very useful in the future of my PhD. :-D May 01 15:08:50 mdp, sigrok with he PRUs might be interesting too for a software based LA May 01 15:09:00 Yeah... I have a few applications in mind... the easiest would be measuring voltages... but I think that is pretty boring. May 01 15:09:57 ka6sox, right. for this case, I was thinking tsquar3d would probably be leveraging some sensor interfaced via IIO May 01 15:10:15 typical spi sensor for *something* May 01 15:11:36 But for the test, I am thinking either magnetic fields or pH levels. May 01 15:12:07 ka6sox, I thought you, panto, and mranostay were already actively working on that PRU LA May 01 15:12:12 The second one -- thinking about my wife, she is a biologist. May 01 15:13:38 Something as boring as temperature could be done... May 01 15:13:59 Point is... it is meant to be general purpose. May 01 15:14:29 https://www.sparkfun.com/datasheets/Sensors/MicroMag3%20Data%20Sheet.pdf May 01 15:14:44 sure, the key here is what is being newly developed? May 01 15:14:58 mdp: Agreed... and what is available. May 01 15:14:59 what new will benefit the community May 01 15:15:05 Ah... yes. May 01 15:18:08 Well, a) a use-case study for the device b) (if successful) a potential market for the device (other than just "education"... which is the pi's primary market atm) c) comprehensive documentation of the ADC. May 01 15:19:34 beagle bone black eMMC and HDMI header pin usage is hurting me May 01 15:19:35 I am all about getting application studies for the general public out there... May 01 15:20:43 If someone asks "what use is this thing?" you should be able to have an answer to excite them. May 01 15:21:31 hi .. how do i run the dhcp client on a beagle bone .. do I have to use conman test every time? or perhaps do I need to use opkg to install a dhcp client? May 01 15:21:45 I would say "oh, that? it's a handheld computer that can take all sorts of data and plot it on-the-go. And it is under $100!" May 01 15:21:50 dhclient is probably already installed. May 01 15:22:03 DotC: try udhcpc May 01 15:22:38 is there a default DT (.dts) file loaded on startup for the BBB ? which file is it ? May 01 15:23:01 And then the teachers start to drool and the uni labs start to drool and tell the administrators "BeagleBone! BeagleBone!" and the admins are all "I have no idea what that is, but the researchers and teacher want it!" May 01 15:23:11 halherta: /boot/am335x-boneblack.dtb May 01 15:23:23 And it becomes a buzzword.... and TI doesn't shut it down for lack of interest. May 01 15:24:44 ... and I would say having the hardware in production because people are interested in buying it is a pretty good thing for the community. May 01 15:24:45 :-) May 01 15:25:04 hi panto, ka6sox May 01 15:25:52 so I would say the big thing you would be creating is a generic IIO collection module for sigrok May 01 15:26:24 panto, you've studied the ever-changing IIO...is this feasible with the current userspace interfaces? May 01 15:26:35 Not "for"... "using". May 01 15:26:36 or are they strictly high-latency? May 01 15:27:13 It would be an inexpensive portable data collection / analysis / visualization module. May 01 15:27:24 tsquar3d: TI shut what down? May 01 15:27:28 * prpplague wonders what tsquar3d is ranting about May 01 15:27:37 with the current sysfs userspace interface no May 01 15:27:46 but I don't see why the high speed interface won't work? May 01 15:28:37 thanks cmicali: are there examples out there for enabling on chip peripherals such as spi and adc? May 01 15:28:45 prpplague: I shouldn't have said "ti", I should have said "vendors". May 01 15:29:01 "vendors and manufacturers" May 01 15:29:12 tsquar3d: referring to what? May 01 15:29:20 The BBB. May 01 15:29:32 I mean BB May 01 15:29:42 panto, I guess it's just as good as usb with the buffering May 01 15:29:53 tsquar3d: hehe not likely to happen May 01 15:30:01 halherta: not sure sorry, personally i got the latest 3.8 kernel @ github.com/beagleboard and modified the am335x-bon.dts file in arch/arm/boot/dts directly May 01 15:30:13 mdp, good and usb in the same sentence? May 01 15:30:23 lol May 01 15:30:35 sorry, you probably think I've been drinking ;) May 01 15:31:09 prpplague: Based on what reasoning? Why keep a project going if there's not a sustainable market? May 01 15:32:16 tsquar3d: hehe, well your statement is based on the assumption that "there's not a sustainable market", which is basically false, so your line of reasoning is false as well May 01 15:33:34 morning Turl May 01 15:34:02 mdp, we are May 01 15:36:23 mdp whats wrong with drinking? May 01 15:36:35 jkridner|work: ok i think most of the folks for GSoC for the userspace-arduino stuff have got their proposals prepared May 01 15:36:59 jkridner|work: i'll need that mentor info asap so i can start to plan around the schedule May 01 15:38:32 prpplague: Enlighten me, then? May 01 15:39:39 Pray tell how use-cases are not important for the success of a product. May 01 15:40:17 tsquar3d: don't have the time nor the desire to do so other than, there are hundreds (maybe thousands) of OEM customers for beagle products, and there are plenty of use cases, hehe May 01 15:40:44 prpplague, +1e5 May 01 15:41:17 So, the response is "we don't need more use cases because we have some already"? May 01 15:41:31 I'd start with the examples that ship with the IDE. May 01 15:41:48 there are more examples than could be made to work. May 01 15:42:06 jkridner|work: yea that is the plan, i meant more of what mentor responsibilties are May 01 15:42:13 I'd rank them in terms of complexity and start with the easiest. May 01 15:42:26 prpplague: I'm speaking to tsquar3d. May 01 15:42:44 jkridner|work: ahh ok May 01 15:43:09 prpplague: giving a set of expectations for you is more complicated, so I'm starting with the easy to solve problem first. :-) May 01 15:43:19 woglinde, the beer goggles sure do make USB look better May 01 15:43:45 * jkridner|work is finding the gsoc mentors to be high maintenance. :-) May 01 15:44:02 jkridner|work: Sorry, I am not sure of where your entery point was in the convo... May 01 15:44:06 * tsquar3d is confused. May 01 15:44:19 jkridner|work, this is all so nebulous and we want clarity! May 01 15:44:32 tsquar3d: use cases. May 01 15:44:50 jkridner|work: Okay? May 01 15:45:35 Oh.. I think I know what you are saying. May 01 15:46:26 jkridner|work: well as i have no experience with GSoC mentoring, i have somewhat at a loss to know what is exactly expected May 01 15:46:38 jkridner|work: Well, what we're going on about is that I am trying to make a case that it would be beneficial to carve a niche for use out in research and education... but prpplague seems to be sying that there is no use for it... May 01 15:47:35 jkridner|work: And the way I have attempted to do that is say... hey, here is a way we could build on the hardware to make it useful to teachers and researchers... May 01 15:47:55 ... and that having that niche would be beneficial. May 01 15:48:02 But apparently my reasoning is flawed. May 01 15:48:17 :-/ May 01 15:48:39 prpplague, ka6sox: there's a FAQ for that: http://en.flossmanuals.net/GSoCMentoring/ May 01 15:49:14 I'm working on an e-mail to level-set expectations from mentors, but I hardly feel like an information bottleneck here. May 01 15:49:38 hello all May 01 15:49:54 * jkridner|work will try to spoon feed... just taking a while as I also have distractions. May 01 15:50:34 i think i may have bricked my beaglebone black already (i just received it two days ago) May 01 15:50:39 those are the worst "manuals" i've ever read... May 01 15:50:54 it's powered on, all four leds are on and steady May 01 15:51:11 ka6sox: they aren't amazing, but I'm being asked for general guidance and not being given specific questions. May 01 15:51:29 * jkridner|work can't exactly say how many hours it'll take May 01 15:51:52 jkridner|work: ok thanks, i'll check May 01 15:51:52 kk May 01 15:51:52 hi May 01 15:52:05 hi May 01 15:52:13 jkridner|work: i just don't want to commit and not be able to provide 100% support May 01 15:52:25 johnmilton: if it never goes past there, you should likely reflash it to unbrick it. May 01 15:52:27 I wouldn't want teh Organization Administrator job. May 01 15:52:33 Is thisthe wrightplace to ask my doubts regarding beagle bone May 01 15:52:49 sankar, yes, dumb questions welcomed... May 01 15:53:04 ok May 01 15:53:09 jkridner: thats what i was thinking May 01 15:53:19 i went out and bought a micro sd May 01 15:53:38 followed the instructions here: http://downloads.angstrom-distribution.org/demo/beaglebone/ May 01 15:53:43 except no luck :/ May 01 15:54:04 Is the design of beagle bone is completely available/open source May 01 15:54:48 <_av500_> yes May 01 15:54:49 sankar: it is open source hardware using available components and running open source software May 01 15:55:11 jkridner: when i execute the following, should i be naming a partition or the whole card without partitions May 01 15:55:13 jkridner|work: So, sorry... I know you are busy and all, but do you think my project is worth it as a use case to help strengthen support for BB? May 01 15:55:13 xz -dkc Angstrom-Cloud9-IDE-eglibc-ipk-v2011.10-core-beaglebone-r0.img.xz > /dev/sdX May 01 15:55:32 johnmilton: whole card. May 01 15:55:36 ok May 01 15:55:42 thank you, i will give that a try May 01 15:55:44 that is a really old image name though, so I hope you aren't using that. May 01 15:55:45 So is that possible to get schematic/layout for the PCB? May 01 15:55:54 oh, is there a newer one? May 01 15:56:12 also, you do need root permissions and be *very* careful not to overwrite your drive. May 01 15:56:21 sankar: google! May 01 15:56:43 sure.. thanku May 01 15:57:13 I'm confused on how you even program the beaglebone May 01 15:57:25 with code May 01 15:57:29 duh May 01 15:57:38 it's a computer May 01 15:57:39 zero and ones May 01 15:57:47 not directly May 01 15:57:52 https://github.com/CircuitCo/-BeagleBone-Black-RevA5 May 01 15:58:27 * jkridner|work still has the task from ELC to write the audio bootloader for BeagleBone May 01 15:58:36 whistle to boot! :-) May 01 15:58:47 jkridner|work: is that the original or a fork? May 01 15:59:32 sankar: https://github.com/CircuitCo/BeagleBone-Black seems to be the new link May 01 16:00:08 Calc: that is the original, from the designer. May 01 16:00:15 thx May 01 16:00:43 afk May 01 16:01:02 * jkridner|work forks to beagleboard repo. May 01 16:02:25 I'm still trying to understand how github is setup, what do you mean it forks to the beagleboard repo? May 01 16:02:27 prpplague, "* Mentors should expect to spend at least 10 hours a week for each student." May 01 16:02:56 ka6sox: for those 10 hours are we required to be sober? May 01 16:03:29 I have more important things to do when sober May 01 16:03:35 sssh...if they are someplace else how would they ever know? May 01 16:03:48 jkridner|work: got time to review my proposal? As to bonescript, you are probably the mentor for summer, I guess May 01 16:03:55 the Balmer Curve... May 01 16:04:34 http://xkcd.com/323/ May 01 16:05:46 also applies to bowling, although the curve is different http://2.bp.blogspot.com/_IJpStFJV1l8/Sia7wDCtp4I/AAAAAAAAAa8/tHPR_1RqLqU/s400/figure+1.jpg May 01 16:11:06 jkridner|work: well, hope you get time to have a review soon. Got class for morning. Talk later. May 01 16:11:53 jkridner|work: are we suppose to get together and review the proposals? May 01 16:14:24 prpplague: review, yes. get together, perhaps. May 01 16:14:50 mdp Okay, so I updated my proposal to include sigrok :-) https://google-melange.appspot.com/gsoc/proposal/review/google/gsoc2013/tsquar3d/1 May 01 16:15:21 tsquar3d, now I don't know where it goes next May 01 16:15:51 check with jkridner|work as I think he approves these..I've never mentored gsoc before May 01 16:16:35 I approve these, but I'm fundamentally looking for connections with mentors as part of the approval process... May 01 16:16:39 mdp: Well, I still need a) A mentor statement on how this could be beneficial to the community, and b) Another community member statement. May 01 16:16:56 it seems it could be a real issue for us and I might limit us to very few slots if we aren't able to overcome this barrier. May 01 16:17:09 it seems the mentors are all really stressed out. May 01 16:17:23 Oh yeah.. and I have to cross-compile my hello world. May 01 16:18:08 From past GSoC experience, friction between student and mentor can really derail the development. May 01 16:18:39 also, multiple mentors really help to increase bandwidth to help the students. May 01 16:19:17 Tag Team Mentoring May 01 16:19:30 Well, I am pretty certain that mdp and I get along quite well. :-) May 01 16:19:47 :-) May 01 16:20:14 but who brings the Chair... May 01 16:20:34 ka6sox: eh? May 01 16:20:43 Oh. May 01 16:20:44 Wow. May 01 16:20:56 Really? Pro wrestling reference? May 01 16:21:02 :-p May 01 16:21:30 tsquar3d, I'll go on record,"The BeagleBone DAQ project will help the Beagle community because the output should include a general purpose sigrok hardware plugin for use with the Linux IIO API. This would enable a lot of other projects to be built on top of this framework." May 01 16:21:31 it was one of the reasons I gave up Cable... May 01 16:21:53 tsquar3d, as far as the rest of it, I'm not qualified to envision other benefits May 01 16:22:18 mdp: That's a paragraph, right? May 01 16:22:38 tsquar3d, ugh, they want a paragraph? May 01 16:22:52 I was trying to keep it short ;) May 01 16:22:57 mdp: It says 1-3 paragraphs. May 01 16:23:02 ok May 01 16:23:02 for a coder that *is* a paragraph... May 01 16:23:20 it filled alot of my screen so I thought... ;) May 01 16:23:20 mdp: I don't blame you.. and I appreciate it... I am going to be grading term papers coming up... sigh. May 01 16:23:33 87 size font does not count. May 01 16:24:13 jkridner|work, what is the limiting factor on # of slots for Beagle? May 01 16:24:24 Although I had a philosophy professor once who was legally blind and he used huge font. May 01 16:24:53 tsquar3d, following jkridner's advice, it's probably a good time to solicit other mentors May 01 16:24:54 I didn't get it from the backlog references. May 01 16:24:57 Although a blind philosopher is a little too cliche for my taste. May 01 16:25:17 * mdp pokes panto May 01 16:25:23 or ka6sox May 01 16:25:30 mdp, I've already poked him first! May 01 16:25:33 mdp: Well, I think ds2 was interested. May 01 16:25:44 ok May 01 16:26:06 I didn't think ka6sox was particularilly fond of my idea... or am I just reading into things, ka6sox? May 01 16:26:39 the Viz stuff wasn't in my area....but sigrok has possibilities... May 01 16:27:17 Well, the sigrok stuff is where I would need help, tbh. May 01 16:28:10 I know viz, but the other stuff (particularilly some of the more low-level hardware stuff) will be a learning experience for me. May 01 16:28:48 But it seems that the mentors have that handled, bagged and tagged. May 01 16:29:02 then thats probably a good focus for this summer. May 01 16:29:10 the issue is BW for the Mentors too... May 01 16:29:15 they don't want to overcommit. May 01 16:29:31 Well, I am sure it is the same for the students! May 01 16:29:32 :-) May 01 16:30:11 unless I'm reading things wrong..there are more students than Mentors currently. May 01 16:30:25 (ones who have spoken up here anyways) May 01 16:31:22 officially: Melange sucks...its dog slow May 01 16:31:34 if that were the only problem... May 01 16:31:53 mru, I'm sure there is more that could be said. May 01 16:33:37 I can't comment on things like minux as I've not used them for eons May 01 16:33:43 ka6sox, I mostly found Viz interesting..I can't help there either as I'm mostly a kernel-ish person May 01 16:33:58 sigrok is closer to something I might be able to help with May 01 16:34:09 but probably not alone ;) May 01 16:34:51 right, sigrok + IIO is a good way to go for making it usable across projects. May 01 16:34:54 And, as I said, data viz is kinda my thing. May 01 16:34:55 :-) May 01 16:36:01 I think the community is saying "The more interesting bit for us is the Sigrok/IIO stuff not the Viz" May 01 16:36:50 ka6sox: I thought mdp just said "I mostly found Viz interesting" May 01 16:37:27 Either way it's fine -- we can focus on that after the data collection bit... May 01 16:37:42 okay I will shut up now...moving along... May 01 16:37:52 *g* May 01 16:38:07 But if it is going to be a novel and useful device in the field, I think that real-time viz is a must. May 01 16:38:20 yes, so we keep hearing May 01 16:39:22 Have you ever done data collection in the physical science ka6sox? May 01 16:39:30 science* May 01 16:39:32 s* May 01 16:40:37 tsquar3d, I *only* found Viz interesting May 01 16:40:59 hi emeb May 01 16:41:41 mdp: Ah... okay... May 01 16:41:46 mdp: Noted. May 01 16:42:00 like a hackaday interesting May 01 16:44:26 back May 01 16:45:01 Right. I'd like to get this in the hands of researchers and educators, though... and the viz would be a selling point, methinks. May 01 16:45:32 Although I would not expect this gsoc to have an emphasis on it, if the mentors are not that interested. May 01 16:48:40 No one actually has a BBB on the shelf/in hand yet, do they? May 01 16:48:50 got 4 of them May 01 16:49:05 When did they come? May 01 16:49:13 last saturday May 01 16:49:22 I ordered from newark.com / element14 the day it came out within an hour or so May 01 16:49:30 Lucky! How do you like them? May 01 16:49:56 pretty cool, lots of bugs/gotchas/etc to work out though. I have full confidence the software teams will get 'em in good order soon. May 01 16:49:56 what revision of the board is shipping? May 01 16:50:01 A5A May 01 16:50:04 Hi woglinde. Wotsnew? May 01 16:51:17 I got one yesterday May 01 16:51:29 Did you have any old capes already to try? May 01 16:51:47 just tiptoed around in it a bit, all I have is the bare board May 01 16:52:10 I don't have any capes yet May 01 16:53:59 What should I look out for? May 01 16:56:35 the Node.JS Bonescript stuff currently doesn't support "pinmuxing", i.e. changing the function each I/O pin is assuming on the fly, it's a work in progress b/c the new version of Linux it uses totally changed things around May 01 16:57:15 I'm not sure what your familiarity/comfort level is with linux, but if you do SSH in and try doing the "opkg upgrade" stuff, be aware you may have to manually force the new kernel to install via "opkg --force-overwrite install kernel-image-3.8.8" May 01 16:58:17 I'm sure it's on my cheatsheet! ;-) May 01 16:58:56 debug access to its serial console requires another device, a 6-pin FTDI serial cable or comparable (e.g. Adafruit's FTDI Friend) May 01 16:59:17 I highly recommend getting one of those if you ever plan on tinkering with more than just bonescript or whatever :) May 01 16:59:39 also if you want to add an SD card for data storage, be sure to preload a "uEnv.txt" file with a few lines in it. otherwise it won't boot as long as the SD card is installed May 01 17:00:13 the uEnv.txt file needs to have: May 01 17:00:16 bootpart=1:2 May 01 17:00:22 mmcroot=/dev/mmcblk1p2 ro May 01 17:00:31 Thanks Spirilis! Have you added these to the wiki? May 01 17:00:38 no, didn't know there was a wiki :) May 01 17:01:53 http://elinux.org/BeagleBone May 01 17:02:39 I don't think they've separated the Black out (god that sounds bad when I say it like that) but the information will be most appreciated! May 01 17:04:18 Maxhirez, what do you want to find out? May 01 17:05:48 @panto-just the general buzz on the BBB at the moment. May 01 17:06:12 all I can hear is... bzzzbzzzzzzbzzz May 01 17:07:03 it's pretty fun so far as someone who lives in screen sessions all day long. Also discovered the fix for dropbear nuking my screen sessions on logout: https://groups.google.com/forum/#!msg/beagleboard/-iNTsNh94HI/faELHCJn_esJ May 01 17:08:09 dropbear is all kinds of evil May 01 17:08:17 mru +1 May 01 17:08:27 I only use it on uclinux devices May 01 17:08:32 av500, it's a bear talk, we need you, stat. May 01 17:08:36 and there it needs a few patches to not fuck up May 01 17:08:43 lol aye May 01 17:09:01 hmm k, openssh is available in angstrom May 01 17:09:21 sshd rather May 01 17:09:33 and one way it fucks up is by dumping _its_ stderr raw into the ssh stream May 01 17:09:44 haha May 01 17:09:45 which makes a client trying to connect spit errors and give up May 01 17:09:46 that's fabulous May 01 17:09:54 and you have no way of seeing the error message May 01 17:09:59 well, tcpdump gets it May 01 17:10:06 right May 01 17:10:14 as if anybody analyzes tcpdump ssh traffic... May 01 17:10:24 but that's not the first thing you try May 01 17:11:46 Thanks guys! Gotta bail May 01 17:13:56 mdp: Okay, I have update my proposal -- included your paragraph and added my own. Now I only need someone else to testify how they think the project would contribute to the community. May 01 17:18:13 tsquar3d: url? May 01 17:18:42 https://google-melange.appspot.com/gsoc/proposal/review/google/gsoc2013/tsquar3d/1 May 01 17:43:57 holy gsoc revision spamming batman May 01 17:45:33 yup May 01 17:47:59 Twice in three hours... I wouldn't exactly call that spamming. :-p May 01 17:48:59 Unless you are talking about the mailing lists. May 01 17:49:02 Then.. yeah. May 01 17:49:05 :-p May 01 18:06:40 <_av500_> panto: eh? May 01 18:07:54 there was a bear discussion May 01 18:07:56 drop bear May 01 18:08:48 <_av500_> these are the best May 01 18:10:24 anyone know where which .dtb file is loaded at boot is set? e.g., what ends up specifying the filename "am335x-bone.dtb" May 01 18:12:05 drop the bear with me? May 01 18:12:35 cmicali, u-boot default env configured in that config file May 01 18:12:39 * biot missed all the excitement May 01 18:12:43 cmicali, find ./ -name am335x-bone.dts May 01 18:12:56 and u-boot loads it the dtb May 01 18:14:05 ahh in uboot config May 01 18:14:08 thanks May 01 18:15:56 hatguy_: give me back my hat May 01 18:18:34 does anyone know where the dividing line is between a FAST and SLOW peripheral is? May 01 18:18:43 (on the am335X) May 01 18:19:18 * mdp wants to state the obvious but... May 01 18:19:51 if you say look at the TRM its NOT there...or any of the referenced documentation. May 01 18:20:43 ka6sox-farfarawa, does figure 10-1 help? May 01 18:20:47 circular references in Literature are NOT helpful. May 01 18:21:05 yeah, I want to say it's somewhere in between fast and slow, but ok May 01 18:22:02 not interconnects I/O pins May 01 18:22:19 there is a fast and slow setting for them May 01 18:22:59 so the I2C module maybe fast on the SoC side...but maybe considered SLOW on the I/O pin side. May 01 18:23:49 back into pinmux HELL. May 01 18:23:53 is there a good way to image the eMMC to copy to another bbb? Just dd/xz the eMMC device onto an sd card? May 01 18:24:06 <_av500_> yes May 01 18:24:14 joy May 01 18:24:24 <_av500_> or dd it over the net May 01 18:24:57 <_av500_> or do a tgz if its mostly empty May 01 18:25:02 <_av500_> should be much faster May 01 18:25:05 nc is a good idae May 01 18:26:05 <_av500_> but why copy on to the other? May 01 18:26:15 <_av500_> dont you have the original image on the pc anyway? May 01 18:27:10 anyone used the can utils on the beagle for can0, like candump May 01 18:27:25 i do, just have been configuring one (removing services, adding software, etc) May 01 18:27:30 and need to clone it to a few other bbbs May 01 18:29:25 mdp, can we all agree that 50Mhz is fast? May 01 18:30:47 mindblowingly May 01 18:32:00 panto: Goodday, Would you mind taking a look at my gsoc proposal? http://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/jj2baile/1 May 01 18:32:23 ka6sox-farfarawa, context is king ;) May 01 18:32:45 my bbb should arrive tomorrow! woohooo :D May 01 18:33:50 jj2baile: new buzzword 'software defined peripherals'? :) May 01 18:34:16 hehe, It rolls off the tongue. May 01 18:35:27 mdp, for a BeagleBone I/O pin May 01 18:35:44 jj2baile: btw i would interested in mentoring your proposal May 01 18:35:51 <_av500_> make we could do software defined I2C May 01 18:36:01 <_av500_> instead of that horrid bit banging May 01 18:36:06 <_av500_> maybe* May 01 18:36:15 mranostay, SDP *is* the new buzzword. May 01 18:37:29 software define all things...? May 01 18:37:39 heh May 01 18:38:14 who knows...maybe the Bone with the right Lovin' can do FireWire :P May 01 18:38:25 Oh. Dear. May 01 18:38:25 are there docs for bbb software dev? something that will explain how to blink an led, for example? May 01 18:39:33 <_av500_> shodan45: google "beagle blink led" May 01 18:39:47 the bonescript examples in the page that gets served by the bbb tells you how May 01 18:39:48 jj2baile, commented May 01 18:40:02 sudo google beagle blink led May 01 18:40:06 ka6sox-farfarawa: someone emailed about bitbanging firewire with GPIOs May 01 18:40:27 ka6sox-farfarawa, ok May 01 18:40:30 I'm thinking the PRUs can *just* about keep up wiht that. May 01 18:41:03 <_av500_> but firewire is dead May 01 18:41:21 <_av500_> better do sata May 01 18:41:38 the bone probably *can't* keep up with that. May 01 18:41:39 <_av500_> mdp: or QSPI? May 01 18:41:49 ka6sox-farfarawa: ? May 01 18:42:02 commented on the submission May 01 18:42:21 hm, thats what I thought, but I don't see any. May 01 18:42:31 wierd..okay May 01 18:42:39 * jj2baile blames it on melange May 01 18:42:48 Fair Assumption. May 01 18:43:09 nope..blame it on me...I did it wrong May 01 18:43:46 there... May 01 18:45:02 Ah yes. Ok. May 01 18:46:18 _av500_, quad read spi IP is pretty fast ;) May 01 18:46:31 <_av500_> on the bone? May 01 18:47:35 jj2baile, I'd be interested in Mentoring you on this proposal/project. May 01 18:48:29 mranostay: ka6sox-farfarawa, Alright, Thanks! May 01 18:49:33 mranostay, just remember I coined that expression :P May 01 18:49:57 prpplague, so did you have a look at my proposal? May 01 18:49:59 Ettus uses Software Defined Radio Peripheral... May 01 18:50:22 tsquar3d: yea May 01 18:50:41 tsquar3d: generally looks good, but not an item that i plan to mentor May 01 18:51:21 prpplague, cool... well, I do need someone to comment on how they think it would benefit the community... if you would be so inclined. May 01 18:51:56 tsquar3d: i'll leave that for someone else May 01 18:52:05 mdp, you are BAD.... May 01 18:52:07 i have my own cat skin May 01 18:52:16 you have me wanting one of these: http://www.ebay.com/itm/4-Axis-CNC-3020-ROUTER-ENGRAVER-DRILLING-MILLING-MACHINE-With-Claw-Chuck-/390390623824 May 01 18:53:00 prpplague, understood. Thanks, though. May 01 18:56:18 these "PRU" things use a custom instruction set? May 01 18:56:51 shodan45, yes May 01 18:57:16 but pretty simple May 01 18:57:53 heh, "no C" May 01 18:58:03 says the pdf May 01 18:58:17 * shodan45 wonders if that's a challenge xD May 01 18:58:45 to write a c compiler for it? Go For it...nobody will complain... May 01 19:00:13 they aren't quite "Go Fast and Turn Left" but they are pretty simple. May 01 19:00:24 HCF May 01 19:00:44 my favourite instruction. May 01 19:01:02 EIEIO is a strong contender May 01 19:01:11 and it has the advantage of being real May 01 19:01:26 don't make beagles catch fire, supply hasn't stabilized yet May 01 19:02:04 lol May 01 19:02:19 my beaglebone might be spending its first night away from home May 01 19:02:35 mru, okay...I guess that counts. May 01 19:02:37 gonna let this baby crank out its gcc magic uninterrupted in my office May 01 19:02:47 and VPN in/ssh in to check up on it May 01 19:02:58 * Spirilis sniff... and I remember when it was only 1 day old :( May 01 19:03:18 Spirilis, is it paper trained? May 01 19:03:32 it better be else I'll be pissed tomorrow morning May 01 19:10:21 mhaberler, let the pru's drive that posting I put here from FleaBay May 01 19:11:20 meaning you own it? May 01 19:11:39 * ka6sox-farfarawa resists temptation to push "buy it now" May 01 19:11:57 hey, that gantry is a joke May 01 19:12:03 great for foam cutting May 01 19:12:25 ka6sox-farfarawa: do it! May 01 19:12:27 I'm only interested in PCB milling May 01 19:12:44 <_av500_> LPKF May 01 19:12:51 oh no wonder... i dialed the fax number May 01 19:13:17 <_av500_> fax? May 01 19:14:26 looks doable wrt stepgens; we dont have a complete gpio hal driver for non-stepgens yet, but that's straightforward and one guy is working on it May 01 19:15:09 _av500_, how much is that device however? $10k? May 01 19:15:44 beagleboard newsgroup is turning into a, "how many ways can you write 'how do i do io access on new beaglebone'" list May 01 19:16:08 <_av500_> ka6sox-farfarawa: no idea May 01 19:16:21 <_av500_> they have been doing that since a long time May 01 19:17:14 ka6sox-farfarawa, I am. my theme song: http://www.youtube.com/watch?v=-u-HCHCuHMg May 01 19:18:39 of course you could control slightly more stable gear including toolchangers with linuxcnc, like this one ;) https://www.youtube.com/watch?v=Kh4YD0d071c May 01 19:19:39 ka6sox-farfarawa: these updates are getting old :) May 01 19:20:05 it is like the time i subscribed to lkml and forgot to put the filter on May 01 19:20:08 _av500_, the TI QSPI IP is so trivial it could be copied in a cheap fpga cape via gpmc May 01 19:20:22 _av500_, still just a glorified shift register May 01 19:23:25 PRU_EVTOUT_2, is going to get worse May 01 19:24:47 ka6sox-farfarawa: i hope ti gets that it's important to make io easy for people, without using nodejs May 01 19:24:55 how do i do io access on new beaglebone? May 01 19:25:19 <_av500_> one does not simply access io May 01 19:25:31 * tsquar3d trololololololo May 01 19:25:34 Does the beagleboardxM have a Single-Link DVI or Dual-Link DVI May 01 19:25:42 <_av500_> single May 01 19:25:58 <_av500_> it wont drive your 4K TV May 01 19:26:03 PRU_EVTOUT_2, do you have suggestions? May 01 19:26:12 _av500_: it will, but not at native resolution May 01 19:26:13 some people think sysfs is easy May 01 19:26:28 I do May 01 19:26:28 mdo: yeah, make an easy to use sysfs interface again, with a kernel module. May 01 19:26:31 mdp: isn't that why they invented it in the first place? May 01 19:26:32 i think it's easy to. May 01 19:26:50 better yet, recompile the old stuff as a kernel module for legacy apps. May 01 19:27:01 and hardware. not break everything that currently exists. May 01 19:27:31 <_av500_> sysfs is gone? May 01 19:27:32 mdp, if QSPI is trivial is it small enough for a CPLD? May 01 19:27:35 beagleboard.org is a community...patches accepted ;) May 01 19:27:53 ka6sox-farfarawa, "trivial" is relative May 01 19:27:58 i had a discussion about this yesterday...don't worry about getting kernel code put into mainline...make this stuff easy for the people buying and using your board to use. May 01 19:28:09 mdp, as I'm discovering about this channel... May 01 19:28:10 :) May 01 19:28:10 you're customer isn't the kernel mainline, it's everyone complaining on the groups right now. May 01 19:28:48 and a demo image (like shipped with the beaglebone) should support the customer May 01 19:29:01 PRU_EVTOUT_2, they have provided a serial port for access via a USB/serial adapter...thats pretty good! May 01 19:29:16 ka6sox-farfarawa, you can do a simple spi implementation in a xc9572...I tested a 65xx bus spi implementation somebody made in my dangerous prototypes xc9572 cpld May 01 19:29:40 ka6sox-farfarawa, the TI QSPI has other features that would preclude that though May 01 19:29:49 kk May 01 19:30:02 however, cplds and fpgas are a little blurred at the highend of cplds from what I've skimmed May 01 19:30:10 so you never know May 01 19:30:15 when i get my black, first thing i'm doing is making a sysfs mux interface for debug. it'll have pin settings too. May 01 19:30:20 mdp: fuzzy logic? May 01 19:30:29 it'll list pins by name or beaglebone pin header name. May 01 19:30:32 blurry/fuzzy...yep May 01 19:30:39 mru, isn't all TI logic that way? May 01 19:30:52 anti-spock logic May 01 19:31:34 pin access will be by header index, and it'll be restricted to header pins. May 01 19:31:43 everyone will use it, i'll get rich, and retire tomorrow. May 01 19:31:46 the end. May 01 19:32:05 mdp, sounds like the 64macrocell CPLD on the SSC will be enough. May 01 19:32:16 s/will/will not/ May 01 19:32:39 PRU_EVTOUT_2, TI only does core u-boot/kernel support for the am335x soc...all the other software comes from beagleboard.org...best to focus your efforts there to encourage that team May 01 19:33:29 isn't that where i am? :P May 01 19:33:42 sure, but you were telling TI to do stuff ;) May 01 19:34:01 TI doesn't give a crap about all this node.js/cloud9 stuff May 01 19:34:01 actually, i didn't realize that. i thought ti was in control of beagleboard.org! May 01 19:34:08 <_av500_> no May 01 19:34:10 <_av500_> we control TI May 01 19:34:14 you control the horizontal and the vertical May 01 19:34:16 <_av500_> controll May 01 19:34:22 controlll May 01 19:34:25 three l's in control, av May 01 19:34:43 Do not adjust your msp430 May 01 19:35:14 contrololololo May 01 19:36:00 mdp, I can put a 322Mhz 256 Macrocell CPLD on the board... May 01 19:37:07 might be enough May 01 19:37:14 maybe, yes May 01 19:37:30 I'm not sure of the resource usage of the gpmc logic May 01 19:37:49 I started looking into this at one time and didn't get far before going back to real work May 01 19:38:13 but that's probably 4x the cells on a 9572 May 01 19:38:50 the gpmc logic is far more than for the simple 65xx bus May 01 19:39:11 and why are we even speculating on this? you had a need for quad spi? May 01 19:39:26 it's only useful with spi flash when considering COTS parts May 01 19:40:03 I thought it meant "Queued" memory controller May 01 19:40:07 not Quad May 01 19:40:29 spi with more wires in simple Midwestern terms May 01 19:40:42 for like MMC May 01 19:40:56 to replace parallel NOR flash May 01 19:41:04 ah, okay May 01 19:41:08 with a low pin count cost effective solution May 01 19:41:13 performance is similar May 01 19:41:48 typically coupled with an XIP-capable caching/burst capable MMIO interface May 01 19:42:03 on the controller, I mean May 01 19:42:06 the wikipedia article says its "queued" DMA like action. May 01 19:42:19 so thats a marketting thing with TI I guess :P May 01 19:42:37 "wikipedia lies" as our local schools tell the kids May 01 19:42:59 http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus#Intelligent_SPI_controllers May 01 19:43:21 yeah, not it May 01 19:43:43 you are talking about: http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus#Multi_I.2FO_SPI May 01 19:44:10 http://www.xilinx.com/support/documentation/ip_documentation/axi_quad_spi/v2_00_a/ds843_axi_quad_spi.pdf May 01 19:44:15 xilinx IP May 01 19:45:19 ka6sox-farfarawa, TI version pictured in here: http://www.ti.com/lit/ds/sprt659/sprt659.pdf near McSPI May 01 19:46:01 ah, I read that as DRAT OMAP May 01 19:46:20 you are not alone May 01 19:46:42 okay enough...I have to finish this SSC design today and get it into review May 01 20:07:07 Just got a new bb black and wanted to get my dallas ds18b20 going like I did on the original beaglbone. However it seems the emmc is on the w1 pin... I need to move this to another pin which I think means doing it in the kernel anyone have any help? May 01 20:20:11 there, now all dlna crap is confined to a separate network segment May 01 20:20:15 does that make me paranoid? May 01 20:21:55 how would I get the beaglebone's hdmi to not underscan? May 01 20:24:01 mru: did you firewall all the things? May 01 20:25:14 most of them at least May 01 20:25:50 wifi is bridged off that segment with more firewall May 01 20:26:11 because stupid protocols don't work across multiple subnets May 01 20:27:43 mru, where is the RFC for stupid Protocols May 01 20:28:28 (yes, I know you can't (easily) do auto-discovery outside your subnet) May 01 20:28:50 not even nmap can do that May 01 20:28:57 well it can...but still... May 01 20:29:09 but why not let those who know specify the addresses manually? May 01 20:29:32 * mranostay mru shakes in May 01 20:29:40 now I'm just looking for a dlna controller for android May 01 20:29:46 Hi, im looking at the example page for GSOC and im wondering exactly what is meant by "secondary processor support". Does this just mean being able to control the processor and peripherals of another board like an MSP430 Experimenter? May 01 20:29:47 there are plenty on the play store May 01 20:29:54 but I need something special May 01 20:29:57 I need one that works May 01 20:30:25 dbartlett, things like PRU/MSP/Arduino May 01 20:30:41 mru: most dlna stuff let you punch in an ip address manually May 01 20:30:54 Turl: none that I've ever seen May 01 20:31:17 I recall seeing some that did May 01 20:31:24 but I gave up on DLNA long time ago May 01 20:31:37 mpd is what I use now May 01 20:31:41 I figured I'd give it another try May 01 20:31:50 since it's supported by some kit I've got May 01 20:33:30 ka6soz-farfarawa, okay, thanks a lot. I have access to an MSP430 experimenter so i'm considering hacking support for that May 01 20:34:40 dbartlett, excellent May 01 20:37:58 1day22h, /me gets worried May 01 20:39:27 What kind of voltage does an MSP430 take to power? May 01 20:40:39 anyone know how to specify an alternate DTB in uEnv.txt? May 01 20:42:22 tsquar3d, datasheet says 2.2 V to 3.6 V May 01 20:43:29 dbartlett, Hmm... so you should be able to connect it to a 3V watch battery... May 01 20:45:50 tsquar3d: perhaps, is it a launchpad or something similar you have? May 01 20:46:08 tsquar3d: http://www.ti.com/lit/wp/swra349/swra349.pdf May 01 20:46:20 MSP430 usually takes 1.8-3.6V DC May 01 20:46:39 the value-line chips usually need at least 2.2V to write their flash May 01 20:48:21 * ka6sox-farfarawa curses the guy who made the GPI/GPO outputs non-contiguous on the Bone :P May 01 20:48:42 Hmm... well, I dont want to write to it.... it is already written to. May 01 20:49:15 Just power it. May 01 20:49:26 .. and not fry it. May 01 20:51:32 mranostay, ping? May 01 20:53:04 mranostay, on your Gist for the GPI/GPO pins..you list input register bit 16 twice for PRU0...is that true? May 01 20:53:35 goes to P9_41 and P9_24 May 01 20:57:00 So.... for the gsoc application -- can I do it in fortran? I already did it in C, but that is boring. May 01 20:57:26 Do you mean the qualification test? May 01 20:57:32 ONly if its Cray Fortran May 01 20:58:04 No, f77 ftw May 01 21:02:59 tsquar3d: I thought you were a labview guy? May 01 21:03:20 PRU_EVTOUT_2, Not a chance in hell. :-) May 01 21:05:37 my second job, everything was written in labview. May 01 21:06:18 i couldn't stand it, so i would write up my own scripts using...visual basic macros in excel. May 01 21:06:40 wat May 01 21:06:46 sounds painful May 01 21:06:52 not as painful as labview! May 01 21:06:59 That's... Pretty painful. May 01 21:07:14 we were testing power supplies May 01 21:07:15 Yea... no proprietary software. May 01 21:07:17 simple efficiency curves May 01 21:07:58 they dropped labview and started using my stupid library when i wrote up an efficiency test in front of my boss in, literally, 2 minutes. May 01 21:08:22 the labview equivalent we were using literally took weeks and weeks for two guys to make. May 01 21:08:36 and was basically unmodifiable. May 01 21:08:39 Meh... I think I will just submit the C code I have.... I cant be bothered to find a fortran cross-compiler as well. May 01 21:09:05 but yeah, you can do h/gpib in excel, and plop the data right into a spreadsheet. lol. May 01 21:09:17 i just got that same ssh_exchange_identification error when trying to SSH to my bbb that others have seen May 01 21:09:23 vba is full vb6, so it can literally do anything. windows api calls and all. May 01 21:09:38 something is off with the stock image it hink May 01 21:09:39 literally and sadly. May 01 21:09:57 I once wrote a gui in VB to track a killers IP. May 01 21:10:13 /winlist hide May 01 21:12:21 wmat: please tell me that isn't a real story :) May 01 21:20:47 mranostay: nothing is real May 01 21:22:00 is the pinmux helper included in the latest demo image? May 01 21:27:21 err, is there any documentation for it? I don't see it mentioned anywhere except git code patches. May 01 21:35:54 who was it that stocked up on the stacking headers? May 01 21:39:34 @Russ, that woudl ahve been me May 01 21:40:06 which part number were they (looking for tail length) May 01 21:40:18 I got them out of China May 01 21:40:37 you can get 1's / 2's out of MajorLeauge electronics May 01 21:40:46 check on one of the cape BOm's for a part number May 01 21:41:25 erm, I was thinking about buying some from you, but wanted to know which ones you had gotten May 01 21:44:00 i've already sold what i wanted to get rid of May 01 21:44:03 rest are committed May 01 21:44:47 ah May 01 21:48:56 * rbarris would like to hear about good choices for small LCD monitors that work well with BeagleBoneBlack May 01 21:49:39 I apologize in advance - got a response earlier today but can't find where I wrote it down. I think I need to modify device tree and rebuild kernel for uart support. Can anyone point me in right direction ? May 01 22:01:26 Hey mentors... do we really need a makefile for the hello app? I mean, is it expected? May 01 22:02:21 how much of an impression do you want to make? May 01 22:05:56 you need to provide exact steps May 01 22:07:46 tsquar3d: yes May 01 22:08:20 mranostay, k. May 01 22:08:34 tsquar3d: if it comes down to it at the end, and theres 2 candidates two choose from and one had the make files, and one did'tn.. May 01 22:08:40 who would you pick May 01 22:08:50 you choose, how much effort you want to put into it May 01 22:09:16 the guy that spent time on making beautiful code than fighting with makefiles. :P May 01 22:09:17 I dunno... the one who did not put a silly amount of effort into a hello world program? May 01 22:10:15 makefiles are the king of legacy stupid extending into the 21st century. May 01 22:10:27 people make their entire career on fancy makefiles^WOE May 01 22:10:37 I will do it -- I mean, it is trivial... no problem. May 01 22:11:35 tsquar3d: you just said " silly amout of effort " May 01 22:11:41 and then said " its trivial " May 01 22:12:23 IMHO it wouldn't be terrible for the gsoc selection test to just copy the google 45minute tech interview format :) to test problem solving skills May 01 22:12:40 Right... assuming one of them made a silly amount of effort for a hello world file. May 01 22:12:40 mrpackethead: does the term *whoosh* mean anything to you? because *whoosh*. May 01 22:12:44 It is fine, I just wanted to know. May 01 22:12:45 PRU_EVTOUT_2: my advice: avoid speaking of that which you do not understand lest you make a fool of yourself May 01 22:13:22 PRU_EVTOUT_2: whoosh.. its the sound of a troll farting May 01 22:14:40 mru: if what i said was false, people wouldn't be moving to cmake and other alternatives as fast as humanly possible. May 01 22:14:55 PRU_EVTOUT_2: people are idiots May 01 22:15:15 PRU_EVTOUT_2: I don't know anyone who moved to cmake or other alternatives May 01 22:15:15 mru: true. which is why we need easy to use tools ;) May 01 22:15:51 (cmake is just a makefile generator anyway) May 01 22:15:51 so, tsquar3d, maybe if you want extra points, provide the maek files, and if theres a better solution that as well May 01 22:16:15 I am happy to provide them.... np. I just wanted to know. May 01 22:16:24 Well... it. May 01 22:16:25 Turl: exactly. makefiles are so convoluted you need a tool to make the tool! May 01 22:16:39 PRU_EVTOUT_2: not at all May 01 22:17:13 PRU_EVTOUT_2, for a non-trivial example, they can be a huge time-saver. May 01 22:17:15 PRU_EVTOUT_2: it's not a valid point anyway, you could say that of UI toolkits even May 01 22:17:50 Turl: tell that to the scons userbase. May 01 22:18:02 I tweaked the hello world code to print the actual date and not just a hardcoded one, did I go overkill? :P May 01 22:18:05 makefiles make simple things easy and complex things possible May 01 22:18:14 PRU_EVTOUT_2: you tell your point to android developers :) May 01 22:18:47 tsquar3d: i'm saying the difficulty of the tool is flawed, not the concept of it. May 01 22:19:01 few things are as simple as a basic makefile May 01 22:19:20 ask them why they build makefiles directly. it'll be something like "that's how it's done" May 01 22:19:43 PRU_EVTOUT_2: then C and assembler are flawed and everyone should use JS or python May 01 22:19:50 Well, I think a good portion of the population would say that few things are as simple as a basic makefile... but... yeah. May 01 22:20:17 And by would, I mean would not. May 01 22:20:45 most people have only seen makefiles as spat out by automake May 01 22:20:51 and _that_ is pure horror May 01 22:21:03 cmake likewise May 01 22:21:07 autohell, no! everyone run! May 01 22:22:04 Does the beaglebone black output audio via HMDI or just video? May 01 22:22:42 I am pretty sure most people dont care what the makefile looks like as long as it makes. Actually, I am pretty sure most people dont know what a make file even is. May 01 22:23:36 tsquar3d:surely the type of person who compiles from source cares what a makefile is ;) May 01 22:24:03 dbartlett, yes.. and that is not the majority of the population. May 01 22:24:11 what a horrible work ethic May 01 22:24:15 I am not saying that they are not important. May 01 22:24:17 you should ALWAYS do your best May 01 22:24:19 we're talking about developers here May 01 22:24:22 instead of taking every shortcut May 01 22:24:37 the majority doesn't even care about how computers work May 01 22:25:06 Turl, yep. May 01 22:25:38 that is pretty much the mantra of today's youth May 01 22:25:41 * crashovrd went there May 01 22:26:40 anyway, take pride in your work. make your makefile something you are proud of May 01 22:26:44 crashovrd, no... you should always be the most efficient. May 01 22:27:20 why clean your house if nobody is coming over? May 01 22:27:26 because YOU have to see it May 01 22:27:34 and its a reflection of YOU May 01 22:28:06 Because it is a waste of time and there are actual important things to be done? May 01 22:28:22 this is obviously work for the sake of work. they are not going to publish your helloworld.c May 01 22:28:45 crashovrd, lol... I am not in any way opposed to it! May 01 22:28:54 it says something about you May 01 22:28:55 I was just wondering if it was expected. May 01 22:29:03 you should work smart, not hard May 01 22:29:09 so whethere 'nobody cares' is not even an issue May 01 22:29:13 the audience is your mentor May 01 22:29:25 in this case smart means making a point that you know how to do the stuff you're asked to, and more May 01 22:29:45 Right -- but the question is, does it say *this guy is the kind of glue sniffer that worries about make files for hello world programs and wont actually get anything done* or *this is the kind of guy who pays attention to detail*? May 01 22:29:50 so 'here is my half ass makefile cuz u stupidly wanted me to waste my time making something nobody will even look at' May 01 22:30:01 is not really the statement you want to make May 01 22:30:28 "this is the kind of guy who worries about how he'll be perceived" May 01 22:30:49 Right... if that is how you read it, yes. May 01 22:30:56 Hence why I am asking. May 01 22:31:11 :-) May 01 22:31:20 you should be able to accomplish "helloworld' on your own May 01 22:31:24 without asking! May 01 22:31:31 ... sigh. May 01 22:32:10 if there was any doubt in your mind about whether a makefile was expected. you should have just made it. May 01 22:32:29 its more efficient that posting the question May 01 22:32:32 wating for reply May 01 22:32:41 debating that reply cuz u think its a waste of time May 01 22:32:42 Well, I guess jkridner should have written "you should be able to accomplish this on your own" rather than "if you have any questions, please ask" in this part of the application. May 01 22:32:47 and then doing it anyway May 01 22:33:17 its helloworld! May 01 22:33:35 just my thoughts on the matter. May 01 22:33:36 ;) May 01 22:33:40 carry on May 01 22:34:01 hello all May 01 22:34:07 hello world! May 01 22:34:11 Yes... and I have never seen a hello world with a makefile... thus why I am asking. May 01 22:34:12 haha May 01 22:34:16 touche sire May 01 22:35:56 then you haven't seen GNU Hello May 01 22:36:18 tsquar3d: maybe its a simple way of broadening a task so if you hit it later you've tackled it before? May 01 22:36:24 * NULLthought shrugs confusedly May 01 22:36:33 Sure.. I believe it... May 01 22:36:43 There. Is. No. Problem. May 01 22:36:47 I just thought it was odd. May 01 22:36:52 So I thought I would ask. May 01 22:36:52 id agree haha May 01 22:36:55 Like it says. May 01 22:36:57 is weird May 01 22:38:18 I got the cross-compiling done... no problem... tested it... documented... saw the makefile and thought... hmm.... it is weird that there is a make file included. Should I add that too? It might look like I am copying if I do... because I would normally not go out of my way for something as small as one line of code... May 01 22:38:38 So, hi. Here I am... asking... like it said.... following directions. May 01 22:39:00 :-) May 01 22:39:57 :) May 01 22:42:26 Whew. May 01 23:01:12 dbartlett, if it doesn't currently it will shortly have audio via the HDMI May 01 23:01:28 mranostay, ping? May 01 23:01:43 ka6sox:thanks May 01 23:03:13 dbartlett, yw May 01 23:07:24 Hey, mranostay, I think you were the one asking me about my code for my application yesterday, right? May 01 23:08:02 Anyhow. Done... https://github.com/trevortomesh/gsoc-application May 01 23:08:43 good luck.. tsquar3d.. May 01 23:08:46 Now all I need is one other mentor to comment on how they think my project might benefit the community. :-D May 01 23:08:54 Im not a mentor on this project May 01 23:09:18 mrpackethead, thanks... and thanks for all the guidance. May 01 23:09:48 Well... it says it does not NEED to be a mentor, but it is preferable. May 01 23:13:05 ds2, are you lurking? May 01 23:38:32 tsquar3d: two things re. your application May 01 23:38:51 Turl, k? May 01 23:38:54 1- your git hasn't been configured with a valid name and email May 01 23:39:05 2- please don't commit stuff as root :p May 01 23:39:37 The first one confuses me and the second one.... well.... fine... you got me. May 01 23:40:02 you're "root " May 01 23:40:11 root ain't your name and that's not your email :) May 01 23:40:14 Ah... yeah.. no.. I gotcha. May 01 23:40:21 Derp. May 01 23:40:40 tsquar3d: https://help.github.com/articles/setting-your-email-in-git May 01 23:40:42 Skippded a step. May 01 23:40:57 name is the same but user.name key on config May 01 23:41:06 Ha... I know how to do it... just kinda forgot to. May 01 23:41:21 Thanks for catching that... May 01 23:41:34 np :) May 01 23:41:53 I am on my piece of junk laptop and forgot that I didnt ever configure that. May 01 23:42:11 haha May 01 23:48:32 Turl, what do you think of it otherwise? May 02 00:01:30 yay! BeagleBone Black is plugged in and powered up! May 02 00:02:53 * vvu|Mobile still waits for that shipping to arrive here :( May 02 00:03:14 I ordered mine from AdaFruit this past Friday, and tadah! May 02 00:03:30 mine shipped yesterday May 02 00:04:08 i ordered from Conrad, germany and i live in germany but they are kinda late i see May 02 00:04:13 They tell me that it will not get to me until next week. May 02 00:04:21 I live in the UK... ordered from franell. May 02 00:04:24 tsquar3d: looks ok May 02 00:05:02 Cool. Thanks. May 02 00:05:12 Conrad germany had "shipping from 30th of may" May 02 00:05:12 You are not mentoring, right? May 02 00:05:32 tsquar3d: no, I'm participating as a student May 02 00:05:50 I'm tempted to apply for the BeagleBone GSoC, but I have too much going on. May 02 00:06:02 vvu|Mobile, dont trust the stated times... contact customer service. May 02 00:06:15 yeah i mailed em 2day but it`s free day here May 02 00:07:59 So, the PCB was designed to fit into an altoids tin, yes? May 02 00:08:16 Are there some standoffs I can purchase so it won't short while running inside the tin? May 02 00:08:17 yes May 02 00:08:29 I put masking tape on the bottom of my tin May 02 00:08:34 oh, sensible May 02 00:08:37 and so much cheaper! May 02 00:08:43 russ++ for better sense than me May 02 00:08:46 otherwise, you can get pretty much anything you want from amazon small parts May 02 00:15:08 i printed up some casess from thingiverse May 02 00:15:22 Has anyone hooked up to the TPS65217 pins yet? May 02 00:17:44 I'd like to keep a LiPo battery under my proto cape and be able to charge it from USB May 02 00:30:42 hmmmmm May 02 00:58:12 Hey ds2 May 02 00:58:34 hey tsquar3d-sleep May 02 00:58:57 who woke you up? ;) May 02 00:59:02 ds2, so I think I have everything in order now... May 02 00:59:07 lol May 02 00:59:13 I was ABOUT to go to sleep. May 02 00:59:25 Then I saw you came on. May 02 01:00:06 Oh so I woked you up ;) May 02 01:00:12 So, all I need to complete my application is for a second mentor to provide 1-3 paragraphs on how my project could help the community. May 02 01:00:13 tsquar3d: found a mentor? May 02 01:00:20 Okay... technically. May 02 01:00:20 lol May 02 01:00:39 I think that mdp is going to mentor me... May 02 01:00:44 ooohh May 02 01:01:07 got a quick 2 sentance description of the project? May 02 01:01:11 Although it never hurts to have more than one. May 02 01:01:18 Sure. May 02 01:01:36 The beaglebone's hardware -- especially the availability of ADC pin headers -- makes it a very good candidate for use as an all-in-one portable data collection and analysis device. Paired sigrok and the IIO framework, we will develop an inexpensive portable module that may be very beneficial to researchers and educators. May 02 01:02:13 I like that May 02 01:02:25 I could probally use that for my power measurement stuff May 02 01:02:35 :-) May 02 01:02:43 Would you be interested in co-mentoring? May 02 01:02:56 Or providing a statement so I can complete my application? May 02 01:03:13 maybe May 02 01:03:27 let see how the mentors distribute out May 02 01:04:09 Okay. Could you see how it might be able to benefit the community? May 02 01:04:25 the most immediate use I can see is it provides an opensource data collection platform which is different from open source data analysis May 02 01:04:33 I should include "hobbyists" in there. May 02 01:04:59 there are many projects that provide O-scope or Logic Analzyer functionality but none (that I know of) that will do long term data collection. May 02 01:05:15 In essence, I see this as a Oscope with a very very very long period May 02 01:05:30 you can grow on that May 02 01:05:56 ds2, ha... I was just looking at it as a daq with a screen. May 02 01:05:57 lol May 02 01:06:12 that also describes a scope May 02 01:06:30 but if you have slower changing data or you need information over a longer period that falls apart May 02 01:06:32 Right... but this beast will actually record the data. May 02 01:06:51 unless you get the more expensive data recorders (be it a paper chart recorder or one of those NI boxes) May 02 01:07:12 you can record stuff on an oscope too but it is for a very short duration May 02 01:07:28 Yeah, I am familliar... May 02 01:07:40 if I understand it correctly, it is a complement to a scope May 02 01:07:55 We had some really expensive oscopes in undergrad. May 02 01:08:08 I been personally looking at hacking scopes to do the long term data monitor stuff May 02 01:08:16 need that for some power management data May 02 01:08:24 or even battery characterization May 02 01:09:08 Well, first and foremost it is meant to be a data collection unit... and the viz will be exceptionally useful for those in the field that would usually have to take data blind and then analyse it later. May 02 01:09:23 I mean... not even analyze, but simply look at it. May 02 01:09:32 sigrok does some of the visualization May 02 01:09:48 ds2, very modest stuff, though. May 02 01:09:57 However, to start out with... that is really all we need. May 02 01:10:00 tsquar3d: I am easily satisfied :D May 02 01:10:21 ds2, lol... that is why you would be an ideal mentor. May 02 01:10:25 :-p May 02 01:10:28 :P May 02 01:10:42 but I am happy to quickly fail people ;) hehehe May 02 01:10:52 I also got the hello world thing up. May 02 01:11:04 The only part I need to finish is another statement from a community member. May 02 01:11:42 not sure who else to direct you to....talked to ka6sox? May 02 01:12:29 I havent ever asked ka6sox directly. May 02 01:15:34 mdp seemed enthusiastic about it and gave me my one statement of support. I am pretty sure he intends on being my mentor. May 02 01:16:48 I have had plenty of people look at my proposal and give the thumbs up... but no dice on someone willing to write a paragraph or two on how it would help the community. May 02 01:17:10 I do still have two days... so I dont think I should be too worried. May 02 01:18:18 1 day and 16 hours. May 02 01:18:57 you could turn what I said into a paragraph May 02 01:19:00 add another person May 02 01:23:52 The most immediate use I can see is it provides an opensource data collection platform which is different from open source data analysis. There are many projects that provide O-scope or Logic Analzyer functionality but none (that I know of) that will do long term data collection. May 02 01:24:52 Any comment addressing exactly how it will impact the beagleboard.org community directly? May 02 01:25:12 Measuring power consumption of a beagle board classic :D May 02 01:25:39 ou have slower changing data or you need information over a longer period that falls apart May 02 01:25:44 Woops May 02 01:25:57 If your project is successfully completed, what will its impact be on the BeagleBoard.org community? Consider who will use it and how it will save them effort. May 02 01:26:04 That is the exact question. May 02 01:26:59 btw, where in the world do you plan to be doing this? May 02 01:27:26 Err.. England? May 02 01:27:30 lol May 02 01:28:09 Is that what you are asking? May 02 01:28:20 yes May 02 01:28:27 thought you were moving to CA? May 02 01:28:37 At the end of the summer. May 02 01:28:46 Ohhh end May 02 01:29:06 Yeah. May 02 01:29:11 I seem recall you had connections to UT, CA, and UK May 02 01:29:33 a move in the middle of GSoC might be disruptive May 02 01:29:54 I was born and raised in US, I live in the UK and am moving to CA in the fall. May 02 01:30:09 *nod* May 02 01:30:11 Yeah.. it will not be until the fall, so the GSoC will be over by then. May 02 01:30:50 I fully intend on carrying this project on after the GSoC, though. May 02 01:30:58 I would like to work it into my PhD. May 02 01:31:31 what are you going to be doing for your PhD? May 02 01:31:55 in otherwords, how much higher and deeper are you piling it? ;) May 02 01:31:55 Data analysis and visualization. May 02 01:32:22 ah relevant stuff May 02 01:32:31 Yep yep. May 02 01:32:40 It could very well be a tool that I use in my PhD work. May 02 01:33:04 or you could be establishing a paper trail for a fake thesis ;) heheh May 02 01:33:05 j/k May 02 01:33:19 Shhh... now they know. May 02 01:34:02 Great... I need to change my identity again. May 02 01:34:08 :D May 02 01:34:53 Okay. So, I think that what I have from you will work.. do you maybe have a sentence on how it could benefit the BB community? May 02 01:35:08 see above May 02 01:35:31 Measureing the power consumption of BB classic? May 02 01:35:39 sure May 02 01:35:54 I thought you were saying that in jest. May 02 01:35:55 lol May 02 01:36:08 no, there is a desired to do that to some decent resolution May 02 01:36:14 existing solutions are pretty crude May 02 01:36:47 but no guarantees I will stand by it as a good use of it ;) May 02 01:37:57 So, you would say -- this tool could be of benefit to the community as a tool to improve and troubleshoot other beagleboard devices? May 02 01:38:09 future and past? May 02 01:39:19 or even other boards May 02 01:39:26 but that might be specific to me... May 02 01:40:53 Okay here is what I have May 02 01:40:55 The most immediate use I can see is it provides an opensource data collection platform which is different from open source data analysis. There are many projects that provide O-scope or Logic Analzyer functionality but none (that I know of) that will do long term data collection. May 02 01:40:56 This tool could be of immediate benefit to the community to improve and troubleshoot other beagleboard devices and community projects. May 02 01:44:14 Are you cool with that? May 02 01:45:07 ssh root@192.168.7.2 (...) ssh_exchange_identification: Connection closed by remote host. any idea what this might be ? May 02 01:45:50 i guess May 02 01:46:19 ds2 is there something I should change? May 02 01:46:32 not off hand May 02 01:46:38 run it by someone else to be sure May 02 01:47:56 Okay... I will try to get feedback tomorrow on my application. I need to get to bed, though... have to teach in the morning. :-p May 02 01:48:13 have fun with the students May 02 01:48:48 The students are great--- it is the colleagues that are a pain. May 02 01:48:53 Gnight all! May 02 01:49:12 And thanks again, ds2 May 02 01:49:50 ds2: can we talk a bit about the error handling for the android boot based stuff? i did a bit of research and only for the rootfs i can do some checking with fsck but for the kernel i have no idea May 02 01:50:18 before i run kexec() i can do a checksum for the kernel image to check its integrity but more than that... May 02 01:51:36 ok May 02 01:51:52 more than that i do not see what error handling i can do May 02 01:52:04 after i run kexec() the adk connection is lost May 02 01:52:16 okay, let me ask you this May 02 01:52:26 after htat happens, and you power cycle the bone, what happens? May 02 01:52:49 after the final kernel is loaded ? May 02 01:52:57 yes May 02 01:53:45 in case of success the fs should have e daemon that will start again adk connection and handle the framebuffer data and pass it to the android device May 02 01:54:00 no no May 02 01:54:23 let say you used your project to download a bad rootfs. it obviously hangs. May 02 01:54:32 after that if you power cycle it, what happens? May 02 01:56:19 i think the best way is to have a label in the android app to show in which state the board is : show in the label if the board is with the kernel+fs from the board or kernel+fs from the Android device May 02 01:56:33 like the user should see if booting was successful or not May 02 01:56:36 answer my question first May 02 01:56:46 does the board hang? or does it go back to download mode or ? May 02 01:57:15 if it hangs the user needs to restart the board and it will load the kernel+fs from MMC and will stay into dwld mode yes May 02 01:57:39 but does not start automatically to download stuff May 02 01:57:39 ah okay May 02 01:57:48 gotcha May 02 01:57:49 so it is not a fail loop May 02 01:58:05 wasn't sure if you attempt to cache the rootfs or not May 02 01:58:33 in that case, yeah.. displaying the status might suffice or require the use of the watchdog (I think the watchdog works, you need to verify it) May 02 01:59:28 yes but still if kernel panics you cannot save something on the sdcard and the device should check that specific file for an output or something May 02 01:59:45 the thingie with the status i would see to be most intuitive May 02 02:00:22 it does save stuff on the sdcard? May 02 02:00:36 so a good kernel + FS download would result in a unbootable system? May 02 02:00:44 no no May 02 02:00:57 i was saying when i run kexec() that output cannot be saved somewhere May 02 02:01:01 to be later checked May 02 02:01:09 ok May 02 02:04:19 i can define a timeout for the booting process and when user sends kernel+fs to the board to start a timer May 02 02:04:36 but it`s awkward, not really ok different boot times May 02 02:23:52 for jtag, does data ever come out on tdo during tms bit-strings?

May 02 02:37:40 eikeon, what version of OSX? May 02 02:37:51 10.8.3 May 02 02:37:51 ka6sox: yes if the schmatic is to be believed May 02 02:38:18 mranostay, I see what is is now..its MODE5 and MODE 6 pins. May 02 02:38:30 yeah May 02 02:38:36 * ds2 tags ka6sox, you're it! May 02 02:38:46 well mux settings May 02 02:38:48 ds2, nope...NOT it! May 02 02:39:09 ollie ollie oxen Freeeeeeee May 02 02:39:51 right pinmux HELL. May 02 02:40:02 ka6sox: you know.. when i do that at a bar, for some reason, i the ladies go the other direction from me May 02 02:40:04 pinmux is not hell.. it is easy May 02 02:40:20 i/find May 02 02:40:22 did i hear that usb->serial is built into the bbb? May 02 02:40:30 PRU_EVTOUT_2: no May 02 02:40:38 PRU_EVTOUT_2: it has been removed from bbb May 02 02:41:15 prpplague, right...this room is *safe* for such comments as there are few women here and I am married anyways. May 02 02:41:26 prpplague: i'm not sure what i was talking about. are you talking about the serial debug console? May 02 02:41:34 PRU_EVTOUT_2, yes May 02 02:42:22 ds2, it is when you have bits 0-5, 7, 14-16 in mode6 and 16 (input only) in MODE5 May 02 02:42:28 hrmm, so how do we view boot errors? May 02 02:42:42 PRU_EVTOUT_2, usb SERIAL cable May 02 02:42:46 PRU_EVTOUT_2: by connecting a serial cable May 02 02:42:57 But only if you can get the cable to work ;) May 02 02:42:58 copy cat May 02 02:43:01 PRU_EVTOUT_2: such as the one eikeon linked May 02 02:43:06 PRU_EVTOUT_2: http://tinyurl.com/c7ozlhc May 02 02:43:12 oops wrong url May 02 02:43:19 * ka6sox looks May 02 02:43:25 PRU_EVTOUT_2: http://www.adafruit.com/products/954 May 02 02:43:32 ka6sox: no pr0n May 02 02:43:32 ka6sox: I have yet to find a TI Pinmux that is consider hellish. other SoC's, yes. May 02 02:43:38 b00ring... May 02 02:43:54 Can you connect via serial while powering via usb? Or do I need to be powering via barrel connector? May 02 02:43:59 ahh, thanks prpplague. May 02 02:44:06 eikeon: yes May 02 02:44:18 PRU_EVTOUT_2: sparkfun.com sells them as well as digikey and mouse May 02 02:44:21 mouser May 02 02:44:29 * prpplague grumbles at being tired May 02 02:44:34 i've got a bunch already. :) May 02 02:44:55 mranostay, can I set GPIO3_18 to output mode and connect up to the output pin? May 02 02:45:14 output 4 mode_5, GPIO3_18 May 02 02:45:33 your note is not specific enough May 02 02:46:22 and what is GPIO0_7 normally used for? May 02 02:46:36 ka6sox: look at the schematic! May 02 02:46:42 LCD cape backlight iirc May 02 02:46:47 prpplague: ? May 02 02:48:28 I did May 02 02:48:45 pinmux HELL May 02 02:49:03 GPIO inputs and outputs are seperate from the pinmux May 02 02:49:30 So, like im noticing the bonexcipt examples on the onboard webserver pages dotn seem to work with firefox . .. May 02 02:49:31 pinmux has to be setup to route the signal but the GPIO has its own settings May 02 02:49:36 works fine with chrome though May 02 02:51:08 Considering BBB for some CANbus dev. Has anyone tried bonescript with CAN? how painful was it? May 02 02:54:29 mranostay, okay I get it now May 02 02:55:08 I jsut need to find the flea and that problem goes away... May 02 02:58:48 lets see...I want to say bad things about the sister of the guy who gave us bits 0-5, 7, 14,15 May 02 02:58:56 * prpplague looks in May 02 02:59:06 mranostay: who summons the plague? **** ENDING LOGGING AT Thu May 02 02:59:58 2013
