**** BEGIN LOGGING AT Fri Oct 11 02:59:58 2013 Oct 11 03:00:42 just curious, but why not use a simple micro? it would be cheaper and (I believe) easier to begin development for Oct 11 03:00:59 simple micro? Oct 11 03:01:05 oooooh Oct 11 03:01:07 b/c Oct 11 03:01:12 I want Python Oct 11 03:02:30 hmm, a micro (or even arduino) i still think would have a lower learning curve Oct 11 03:02:40 We are using python to record input from http://www.naturalpoint.com/optitrack/products/arena/ Oct 11 03:02:48 Two EEG's Oct 11 03:02:59 and incorporating all of this through LAN Oct 11 03:03:18 basically, the EEG recording being initiated will create a light on event Oct 11 03:03:32 and help synchronize the video Oct 11 03:03:52 I don't want to use USB cable Oct 11 03:03:52 interesting project Oct 11 03:04:13 I would be happy to send pictures to you, or even video once done Oct 11 03:04:20 we are hoping to begin trials soon Oct 11 03:05:34 ping me on here, I'd like to see this thing working Oct 11 03:05:40 will do Oct 11 03:06:11 if you have time, post on the beagleboard mailing list / google group with what you have done on the bone. I'm sure many people would find it interesting (especially if you include code :P) Oct 11 03:06:41 not proprietary code mind you! just the generic python for using bone pins Oct 11 03:06:48 more examples are always good Oct 11 03:12:09 I will! Oct 11 03:12:18 Never would have thought to look @ mosfet Oct 11 03:12:24 Really appreciate it! Oct 11 03:12:43 Off to Radioshack Oct 11 03:25:58 hello, have the following goal: use a beagleboard, running android, to test regular android apps i write. to do that, I would need to be able to interact with the UI .. so I need the screen shown (which can respond to mouse clicks) on my desktop; as well as my desktop keyboard events going to the beagle. is this possible ? Oct 11 03:30:34 g00s: should just be a matter of getting android up and running.... what's the purpose of using the beagle though you can run android in an emulator on your desktop Oct 11 03:30:58 ... unless you already have a beagle Oct 11 03:31:55 thurgood the emu is notoriously slow; x86 images have their issues too. i'm using genymotion at the moment, but it doesn't have bluetooth. i really need that ;) Oct 11 03:33:13 i would think a 'normal' install of android running on the device would require a panel (if it wasn't being used for embedded linux device). i'm trying to avoid that by bringing the device's graphics to my desktop Oct 11 03:33:44 so im trying to get into the whole angstrom => beagle magic Oct 11 03:33:51 any docs on how the whole sd boot works Oct 11 03:36:05 is there any docs on what the LEDs indicate during boot? Oct 11 03:36:09 i.e. do i have a bad flash? Oct 11 03:36:12 or whatever Oct 11 03:36:58 g00s: for starters which beagle are you considering... the beagle bone black is what a lot of people seem to have moved too recently Oct 11 03:37:21 thurgood i don't have either; i would use what is deemed most appropriate Oct 11 03:37:23 i have the bone black Oct 11 03:40:10 i would just like to know if others have done this, and there is some well travelled route - that would be good enough to satisfy my curiosity atm; i can delve deeper at a later time (assuming its possible) Oct 11 03:42:03 g00s: I'm not sure where android support is for the bbb especially if you need any 3d support you may have better luck in #rowboat if that's on this same server Oct 11 03:42:29 ok, thanks - only need 2d Oct 11 03:43:00 and are you talking about using vnc/etc rather than a dedicated display? Oct 11 03:43:58 vnc - like experience is fine Oct 11 03:44:28 i'd like the " vnc " window on my desktop as if it was the android emu or genymotion Oct 11 03:46:05 should be doable especially on the xM, but the bbb is a much cheaper solution and may work nearly as well, in either case you'll need your own bluetooth solution, dongle or whatnot Oct 11 03:46:57 thurgood thanks ;) Oct 11 03:47:09 most of the people in this channel are using more traditional linux distros rather than android, which is why I suggest checking out the androd channel Oct 11 03:47:39 the android channel being #rowboat Oct 11 03:47:47 android-dev is pretty much just apps; #android - i think thats dead these days but i'll try Oct 11 03:47:56 ah, #rowboat - ok Oct 11 03:47:59 thx Oct 11 03:49:21 not trying to chase you away or anything, just think you'll get better answers to android on beagle there Oct 11 03:53:17 sure, thanks :) Oct 11 06:35:24 Hello! Do I have to turn on the VDD 3.3V? Or can I just plug in my beaglebone black, hook up a pin out & expect 3.3V. I am trying to control a mosfet. Ty! Oct 11 06:35:47 I/O pins output 3.3V Oct 11 06:36:17 sooooooo, I'm assuming I need to use some GPIO on/off before I can get some voltage? Oct 11 06:36:42 I've never used mosfet's before Oct 11 06:36:54 my Vthreshold is 2.0V to 4.0V Oct 11 06:37:19 and I was looking for an instant gate voltage on the mosfet Oct 11 06:37:54 pins configured as GPIO and output will output 3.3V Oct 11 06:40:35 Has anyone run BONE_D64.exe on Win8? Oct 11 06:40:48 I can drop down to Win7 or WinXP if need be. Oct 11 06:40:56 Heck, I'll even go to debian... Oct 11 06:40:57 lol Oct 11 06:42:05 Currently getting http://mekanical.com/error.png Oct 11 06:43:07 Found the fix, and sorry for putting this in IRC logs! Oct 11 06:43:07 https://groups.google.com/forum/#!topic/beagleboard/_y-fIgg-J7I Oct 11 07:02:46 at least he posted the link to the solution? Oct 11 08:36:20 hi! Oct 11 09:40:06 Hi everybody Oct 11 10:00:45 anybody knows Javier Martin ? Oct 11 10:02:21 Martin or Martinez? Oct 11 10:02:43 javier_ in #linux-omap Oct 11 10:02:45 maybe? Oct 11 10:16:16 Is RobCNelson on here? Oct 11 10:42:24 Hello Oct 11 10:43:10 Does the beagleboard have support for openCL ? Oct 11 11:03:55 Jeckle: opencl is software. the beagleboard runs software Oct 11 11:17:28 brothers Lumière open at 11 Oct 11 11:17:47 hello, any techs here? Oct 11 11:17:57 maybe Oct 11 11:18:26 Can't get video to work after update to 2012-09-?? Oct 11 11:18:47 hdmi doesn't sense bbb on boot Oct 11 11:19:23 check the cable, I have had problems with mine. I thought it was just the cheap microHDMI cable Oct 11 11:19:30 errr 2013-09 I ment Oct 11 11:19:49 what board rev? Oct 11 11:20:08 I did. never touched it before, during or after update Oct 11 11:20:25 a5c Oct 11 11:20:37 I have Rev A5B, the later Rev A5C board has a few resistors changed to address HDMI issues Oct 11 11:20:58 have you tried readjusting the cable during boot up? Oct 11 11:21:03 Worked fine before update Oct 11 11:21:42 yes I unplugged it, checked the tiny little pins. plugged it back in wiggled it... nothing Oct 11 11:21:49 can you try downgrading ? Oct 11 11:22:20 I can I assume... how many times can you reburn the emmc on these things? Oct 11 11:22:46 I have my BBB powered from the 5V cosket, and the usb connected to this workstation for the serial console Oct 11 11:22:52 lots Oct 11 11:23:14 I read somewhere there was a limit. Oct 11 11:23:26 but never gave a number Oct 11 11:23:49 ok I'll try that for now.... Oct 11 11:24:01 thanks for your help Oct 11 11:24:03 what I have trouble comprehending is why people are so dead set on reflashing the emmc, when you can easily use the uSD card to boot Oct 11 11:29:45 it is shiney Oct 11 11:30:01 eh? Oct 11 11:41:45 Hey. Oct 11 11:47:01 http://pastebin.com/wpD1GtUj I'm looking to resolve that compiler error for ViewRF Oct 11 11:47:09 morning ZiNC Oct 11 11:47:22 Hi N2. Oct 11 11:48:44 know about compile errors? Oct 11 11:49:17 Far from it. Oct 11 11:50:44 Say, any opinion on BB vs RPI in terms of community? Oct 11 11:51:39 yeah I have both, the BBB has more processing power+ 2 PRU cores that can be dedicated to GPIO, the RPi has better video output Oct 11 11:51:57 Not spec-wise. :) Oct 11 11:52:05 How active the community is. Oct 11 11:52:23 I think there are at least 10 times more RPIs in the wild, Oct 11 11:52:27 so more people around. Oct 11 11:52:39 not sure about that, but the applications are also different Oct 11 11:52:41 When you need help, that is. :) Oct 11 11:52:57 10 times more noobs Oct 11 11:53:06 :) Oct 11 11:53:16 I don't seem to have trouble locating people, but then again I have a talent for finding odd bugs in almost anything Oct 11 11:53:29 Well, looking at BBB specifically, it's newer than RPI. I guess that's also a reason. Oct 11 11:53:33 lol yes never a shortage of them Oct 11 11:53:42 How are the applications different? Oct 11 11:53:51 Obviously it's not 100% the same, but there's more overlap than there isn't. Oct 11 11:54:16 the BBB will run more workstation oriented linux distros Oct 11 11:54:30 I have run Ubuntu and Angstrom on it Oct 11 11:55:01 Is there an inherent reason for it, or just because people already worked on that? Oct 11 11:55:37 Though I'm starting to suspect it's all theoretical in my case, and BBB would be a better match. Oct 11 11:55:37 it's a hardware difference, the BBB uses a later generation ARM processor that already has greater code support Oct 11 11:55:44 Oh v7. Oct 11 11:55:47 yeah Oct 11 11:55:53 Okay. Oct 11 11:56:03 But the rpi can encode/decode videos Oct 11 11:56:18 I'm more interested in USB. Oct 11 11:56:33 for example backtrack should run on the BBB, bit without the source it will not run on an RPi Oct 11 11:57:13 What's the quickest likely boot on BBB? Oct 11 11:57:13 * N2TOH IMHO the RPi it targeted more to home entertainment and tinkering Oct 11 11:57:27 a few seconds Oct 11 11:57:27 And BBB? Oct 11 11:57:45 industrial applications and automation Oct 11 11:57:46 How few? 10 is a lot. 5 is workable. 2 is good. Oct 11 11:58:06 I can reboot it now can count the seconds if you like Oct 11 11:58:14 Sure. :) Oct 11 11:58:19 What does it boot? Oct 11 11:58:29 angstrom from a class 10 uSD card Oct 11 11:58:43 Is the internal flash slower? Oct 11 11:59:41 about 8 seconds to boot after about a 5 second shut down Oct 11 11:59:52 Thanks. Oct 11 11:59:55 vanilla debian is significanly slower to boot Oct 11 11:59:59 I'm not 100% about the internal emmc speeds Oct 11 12:00:07 Shut down... Oct 11 12:00:18 I also have the swappiness lowered from the default of 60 Oct 11 12:00:24 Is the bottleneck there the storage? Oct 11 12:00:31 Or the hardware init? Oct 11 12:00:35 I think it is Oct 11 12:01:19 I know of the RPi it's the SD card, as a high end USB drive makes an enormous difference Oct 11 12:01:22 I wonder if what's loaded at boot could be minimized to speed it up. Oct 11 12:01:46 also the order of booting Oct 11 12:02:07 I.e., starting with the internal, then going elsewhere? Oct 11 12:02:30 What happens on shutdown, BTW? Oct 11 12:02:49 screen goes blank, then it pulls a reset vector Oct 11 12:02:56 I mean, why 5 seconds? Oct 11 12:03:05 What won't happen if you just turn off power? Oct 11 12:03:11 IHNFK Oct 11 12:03:24 Is that a valid acronym? :) Oct 11 12:03:35 writing out to the flash drive for one thing Oct 11 12:03:50 I have no fine klue Oct 11 12:03:58 Oh, korrect, korrect. Oct 11 12:04:05 Writing what? Oct 11 12:04:15 contents of ram to disk Oct 11 12:04:16 Well, I guess that part could be speed up to about 0 seconds rather easily. :) Oct 11 12:05:04 I have yet to play with the file that controls the boot options Oct 11 12:05:29 I have been told it can be modified to allow the selection of the boot device appon power up Oct 11 12:05:43 IE boot from emmc, uSD, USB etc etc Oct 11 12:06:05 I suppose even a DVD or CD even Oct 11 12:06:12 :) Oct 11 12:06:27 I want floppy support. Oct 11 12:06:31 Is there any recommendation for the slewctr on i2c 100k? Oct 11 12:06:31 360K Oct 11 12:07:20 no idea there was a guy in here the other day asking about i2c, seems he was having issue with 3v3 and 1v8 logic Oct 11 12:07:42 you cannot boot from DVD Oct 11 12:07:55 haha yeah USB floppy boot support would be good for a few laughs Oct 11 12:07:55 N2TOH, and it was about the slewctrl? Oct 11 12:08:16 what about it? Oct 11 12:08:17 N2: Why USB? Connect it directly! Oct 11 12:08:32 no, it was more about how to interface a 3.3v volt sensor the the 1.8V i2c port Oct 11 12:08:49 av500, fast or slow slewctrl on 100k Oct 11 12:08:59 cause a floppy controller would be more work Oct 11 12:09:37 refresh my memory about the slew rate options for i2c Oct 11 12:09:46 More lightweight than USB, I suppose. Not that it matters, really. Oct 11 12:10:09 usb floppy drives can still be purchased new Oct 11 12:10:33 but I do still have a pile of them in the other room Oct 11 12:10:37 I Oct 11 12:10:50 I'm sure you can purchase floppy-interface floppy drives new Oct 11 12:10:57 sure Oct 11 12:11:20 just bitbang it Oct 11 12:11:33 floppy drives are not like PATA IDE drives, they need an interface chip on the contorller Oct 11 12:11:35 But that couldn't possibly be faster than 30K/sec! Oct 11 12:12:24 from what I recall the read/write heads are wired directly to the controler chip on the interface card/mother board Oct 11 12:12:41 IE the I/O is analog Oct 11 12:15:08 mmm I thought it was a 250kbps serial Oct 11 12:15:43 I never hacked around with it though Oct 11 12:16:00 if it were that easy I would still use them Oct 11 12:16:26 Use for what? Oct 11 12:16:37 floppies were a essay in how to get things done as cheap as possible Oct 11 12:16:52 storage for AVR projects Oct 11 12:17:26 but the cost of SD cards is dropping so it's becoming pointless other then for amusement Oct 11 12:18:40 http://pinouts.ru/Storage/InternalDisk_pinout.shtml Oct 11 12:18:53 on that, RDATA and WDATA are serial I think Oct 11 12:19:14 falling edge indicates a transition in the magnetic state of the media Oct 11 12:19:16 Besides amusement, or unless you need to access old diskettes, I don't see how floppies could be an interesting storage medium in the last 15-20 years. Oct 11 12:19:57 http://www.youtube.com/watch?v=dmoDLyiQYKw Oct 11 12:21:03 First category above. :) Oct 11 12:22:18 http://bitsavers.informatik.uni-stuttgart.de/pdf/shugart/_appNotes/39003_SA400_8080_1771_App_Note_Nov77.pdf Oct 11 12:22:25 mmm... look at those fonts.. :) Oct 11 12:23:21 Very authentic. Oct 11 12:30:09 BUHAHAHA I haven't seen that document since I was a kid in the 80's Oct 11 12:34:29 that pdf was created the year I was born Oct 11 12:38:48 same here Oct 11 12:39:02 the document not the PDF Oct 11 12:40:24 well yes, the document Oct 11 12:41:14 an Unckel of mine used to work for Xerox, with the lack of CATV I got to read all the technical documents he had Oct 11 12:43:11 -c* Oct 11 12:45:19 Which one? Oct 11 12:47:17 Any idea what's the difference between BBB A5A and A5B? What's said on the wiki is very vague. Oct 11 12:47:23 http://circuitco.com/support/index.php?title=BeagleBoneBlack Oct 11 12:47:40 "the modification that was being done"? Oct 11 12:48:59 ZiNC, the only difference between the a5b and the a5c is the resistors used for the HDMI output. it was a small tweek to inprove the production yield Oct 11 12:49:30 But I wonder about 5A -> 5B. Oct 11 12:51:13 there were some early problems, namely signaling on the board and usability issues, as the BBB brings out almost all it's IO pins and that can cause bus errors based on where the traces go on the board Oct 11 12:53:01 What's "THE modification"? Oct 11 13:14:57 Recently got a BeagleBone Black rev. A5C with Angstrom 2012.12, whilst taking a screenshot it crashed... Its now done it 3 times and now refuses to boot. Oct 11 13:16:23 What are my options? Oct 11 13:16:41 can you boot from an SD card? Oct 11 13:17:30 I don't know yet, waiting for BBB-eMMC-flasher-2013.06.20.img.xz to download Oct 11 13:18:20 Should there be a problem geting BBB to act both as USB host and client simultaneously? Oct 11 13:19:35 ZiNC: On different ports? Oct 11 13:19:39 Yeah. Oct 11 13:19:56 I guess the host/client ports can't switch roles anyway? Oct 11 13:19:56 no. thats how it works out of the box Oct 11 13:19:58 was in the process of updating it using opkg. The action that crashed the BBB was creating an image within GIMP from a timed screenshot. Not sure what point the opkg was at, either downloading or applying the updates Oct 11 13:20:16 ZiNC: actually they can Oct 11 13:20:19 Really? Oct 11 13:20:28 How does that work? Oct 11 13:22:03 The mode is configured in device tree. I'm not sure if any minor hardware modifications would be needed but on a different board using the same CPU I have them both setup for host Oct 11 13:22:22 What board? Oct 11 13:22:36 Does this imply OTG, BTW? Oct 11 13:22:50 Isn't there a 5th line for that? Oct 11 13:23:27 I think OTG is a different mode. Let me look Oct 11 13:23:29 the 5th pin is needed only for auto-selecting mode based on the attached cable Oct 11 13:23:51 guys the BBB has both a Host and a device USB port Oct 11 13:23:57 you can always force the port to either host or device mode Oct 11 13:24:20 If it can be done with both ports, that could be useful. Oct 11 13:24:27 no Oct 11 13:24:31 No? Oct 11 13:24:40 the controller supports it, the phys and whatnot might not Oct 11 13:24:47 mru: You mean OTG, or specifically the BBB ports? Oct 11 13:24:55 other then USB OTG, the ports can not be changed Oct 11 13:24:55 the bbb Oct 11 13:25:23 Wait. So can they be forced on the BBB or not? :) Oct 11 13:25:29 the musb controller on the chip is an otg controller Oct 11 13:25:36 Okay. Oct 11 13:25:56 So it's just a question of wiring? Oct 11 13:26:02 it's probably possible to wire the external bits such that only one mode works Oct 11 13:26:07 and I don't know how the bbb is wired Oct 11 13:26:14 The RPI B has a problem due to the integrated hub. Oct 11 13:26:23 no hub here Oct 11 13:26:26 Yeah. Oct 11 13:26:36 I think mode 3 is auto selecting, mode 2 is client, mode 1 is host. Oct 11 13:26:37 If it can be switch no the fly, that's be ideal. Oct 11 13:26:42 ed Oct 11 13:27:03 N2TOH: Did you play with this? Oct 11 13:27:25 What's a small USB hub board that can be hooked easily to the BBB? Oct 11 13:27:33 any Oct 11 13:27:45 ZiNC: This is the board I was using: http://phytec.com/products/system-on-modules/phycore/am335x/ Oct 11 13:27:45 If the BBB can be turned dynamically, then it may not be needed. Oct 11 13:28:01 But if that's not the case, I might need a hub to get two hosts + client. Oct 11 13:28:22 the bbb has two physical usb connectors Oct 11 13:29:00 one full-size A and one mini-AB Oct 11 13:29:08 Without dynamic role changing I'd need 3. Oct 11 13:29:35 the mini connector can probably be used in either mode Oct 11 13:29:51 just try and see Oct 11 13:30:16 connecting a device to it won't fry anything Oct 11 13:30:17 mru: I suspect it can also Oct 11 13:30:21 I'm far from that stage. Still background research. :) Oct 11 13:31:36 I didn't need dynamic role changing so once I got two working host ports I was satisfied and haven't looked at it since :) Oct 11 13:31:40 mru: You mean the mini is more likely to be switchable than the A-type? Oct 11 13:32:18 it's an otg connector Oct 11 13:32:26 Oh. Oct 11 13:32:27 aka mini-ab Oct 11 13:32:30 5-pin Oct 11 13:32:42 right, selectable by the cable, correct? Oct 11 13:32:49 Are there 4-pin minis? Oct 11 13:32:58 Too many connector types... Oct 11 13:32:58 yes Oct 11 13:33:15 haha a OTG cross over cable Oct 11 13:33:31 georgem: I think there's a problem with that on RPI A even though the USB port is wired directly and there is nominally OTG support. Not sure if it's due to a lacking driver, or what. Oct 11 13:33:42 N2TOH: nothing to cross Oct 11 13:33:50 usb is half duplex Oct 11 13:34:07 ZiNC: the rpi usb controller is a piece of shit Oct 11 13:34:21 But in case that doesn't work, what are some cheap USB hub mini boards? Oct 11 13:34:25 I know, the OTG cables typically determin if the OTG port is host/device Oct 11 13:34:43 mru: The BBB USB driver isn't open source, right? Oct 11 13:34:58 it is Oct 11 13:35:03 Oh. Oct 11 13:35:09 no stinkin' blobs on the beagle Oct 11 13:35:11 That's nice. Oct 11 13:36:04 mru, the joke would be a OTG cable with the same connector on both ends and a switch to select the direction Oct 11 13:36:37 I haven't been able to get my bbb to boot from the sd card and am not sure what i'm doing wrong. When i hold down the button and then go to powerup only the power light turns on Oct 11 13:37:05 how long are you holding the button down? Oct 11 13:37:06 N2TOH: what would the switch do? Oct 11 13:37:14 there's nothing to switch Oct 11 13:37:19 Hmm... maybe my keywords are bad, but it seems it'd be cheaper to get a complete USB hub device rather than a board? Oct 11 13:37:23 N2TOH, two, maybe three minutes Oct 11 13:37:45 mru, it's a feature that makes the cable cooler the all the other :P Oct 11 13:37:56 these are the steps i followed Oct 11 13:37:57 http://avedo.net/653/flashing-ubuntu-13-04-or-debian-wheezy-to-the-beaglebone-black-emmc/ Oct 11 13:38:03 N2TOH: there is also HNP, where the devices decide who is to be host Oct 11 13:38:03 yeah that's WAY too long only a few seconds is needed Oct 11 13:38:23 N2TOH: it's not like ethernet where there are separate rx and tx wires Oct 11 13:38:30 i tried doing debian, but i have heard that sometimes debian is glitchy, so i'm thinking i'll try ubuntu Oct 11 13:38:32 mru, I know Oct 11 13:39:02 * N2TOH knows people have trouble determining when I am making a joke and when being serious Oct 11 13:39:28 N2TOH, everything i've see says "hold the button till the lights turn on" so i kept holding Oct 11 13:39:37 * N2TOH needs to invert the joke bit Oct 11 13:40:02 mariner, yeah that should not take more then 10 seconds Oct 11 13:40:22 so then somethings wrong with the card being not bootable, i assume Oct 11 13:41:03 * N2TOH is still fussing for a few weeks now on how to install ViewRF for an SDR application Oct 11 13:45:12 * mariner just tried with ubuntu... still nothing Oct 11 13:45:44 my sd cards aren't the greatest ever.... could that be the problem? Oct 11 13:47:36 that button seems to have caused a lot of problems. a jumper probably would have been a better idea. Oct 11 13:50:31 i get no lights Oct 11 13:52:49 You don't have access to uart0 I suppose? Oct 11 13:52:57 hi all, I need to toggle some relays connected to Beagle GPIO by mean of simple webpage from Beagle itself Oct 11 13:54:04 Freddie: 1) that's simple, just use some GPIO Oct 11 13:54:18 several days of web surfing without a ready or suggested project to work around, (I'm not able to programming thing level) Oct 11 13:54:28 Freddie: 2) dont forget to add some circuitry at the GPIO to drive the relay Oct 11 13:54:38 Could you please suggest some starting point ? Oct 11 13:54:39 Freddie: 3) do _not_ connect the relays directly to the GPIO Oct 11 13:54:55 Freddie: ok... 0) learn programming Oct 11 13:55:10 Freddie: you cannot expect to do programming work without being able to program something Oct 11 13:55:26 KotH : Hardware isn't a problem at all , programming is my fault !!! Oct 11 13:55:58 so, then learn it Oct 11 13:56:09 there are thousand of good programming books around Oct 11 13:56:19 ...I'm too old.... Oct 11 13:56:32 too old to learn something new? Oct 11 13:56:35 wooden brain... Oct 11 13:56:47 then burn your brain and make space for a new one Oct 11 13:58:58 hi... always thought this... anyway , for any suggestion I'll stay tuned Oct 11 14:00:00 well... Oct 11 14:00:27 you are asking for a house to magically appear, without building one Oct 11 14:02:22 if you cannot build it yourself, the only way to do it is to pay someone else to build it for you Oct 11 14:11:37 I found how to light up a led via beagle ubuntu shell , recall a script from an html page button shouldn't be so difficult, (i used to do times ago) Oct 11 14:11:52 but i don't know if it's the right way... Oct 11 14:12:26 If I want to grab some gpio in a kernel driver can I grab GPIO1_7 and GPIO1_8? Oct 11 14:13:21 I need a guide to what pins are free and available that isnt in the impregnable form of the SRM :D Oct 11 14:14:51 exosyst: that guide is called "schematics" and is available on www.beagleborad.org Oct 11 14:20:05 I'm trying to make sense of the schematics but the MUXing is confusing to a softy. I just want to know which GPIO come out of the headers that I can drive :( Oct 11 14:20:55 that's written in the TRM :) Oct 11 14:23:08 KotH, And no nice little webby thing exists that tells me I can grab Pin 15 on P9, it's free and that GPIO1_16? Oct 11 14:23:30 (am I reading that right? - as I could knock up a webscript for it :D) Oct 11 14:25:02 exosyst: real men (i.e. EE's) do it just by looking at the pinmux tables and the schematics ;) Oct 11 14:25:16 writing an app takes more time than looking that stuff up when you need it Oct 11 14:25:45 Yeah but with some help on the lookup, that one script I write could help a few hundred hobbyists :D Oct 11 14:26:58 Where are the pinmux tables? Can I not use the pin I expected? I wanted to do a gpio_request_pin(32 + 16) and have it work Oct 11 14:27:09 exosyst: feel free to do so :) Oct 11 14:27:21 the pin mux tables are in the TRM Oct 11 14:27:27 (technical reference manual) Oct 11 14:27:36 see the ti page for the am35xx Oct 11 14:29:35 The crucial support is knowing how to do the lookup - "pinmux" appears 5 times in the TRM... pin mux a few hundred. This sucks Oct 11 14:32:37 exosyst: well, every TRM is structured differently, uses different key words etc Oct 11 14:32:46 exosyst: you have to read it a couple of times to get the hang of it Oct 11 14:33:15 exosyst: but if you want to do anything usefull with a certain cpu, you do want to know what is written where in the TRM. there is no way around that Oct 11 14:34:14 Ugh. Can anyone suggest good forums for BBB? Google Groups is bad. Oct 11 14:34:39 what's wrong with emails? Oct 11 14:35:25 My current favorite forum method is something like phpBB, vB, etc. Oct 11 14:35:36 What Win software do you recommend for mailing lists? Oct 11 14:35:57 so if i'm trying to boot up from the sd card, does it matter if i power it via usb? Oct 11 14:36:21 ZiNC: the best way to find wrong information on the web is to look for webforums Oct 11 14:36:33 Not in my experience. Oct 11 14:36:36 ZiNC: especially those using phpBB, vB, etc Oct 11 14:36:39 Usenet is not longer useful. Oct 11 14:36:48 that's why most people switched to mailinglists Oct 11 14:36:52 KotH, Where would you suggest I start if I just want to know what pin i can call gpio_request_one() on? Oct 11 14:37:11 exosyst: schematic Oct 11 14:37:15 exosyst: look what's free Oct 11 14:37:27 exosyst: work back to the cpu pin Oct 11 14:37:40 exosyst: check the TRM/datasheet what gpio it corresponds to Oct 11 14:38:33 And free implies that it comes out of P8 or P9 and is set to GPIO - e.g. GPIO1_16 and GPIO1_17? Am I following? Oct 11 14:38:59 check what gpio the gpio corresponds to? I'm confused KotH, how do you mean? Oct 11 14:39:50 KotH: Mailing lists vs. web aside, you have to agree for web forums Google Groups is almost as bad a choice as you can make. :) Oct 11 14:40:16 exosyst: a physical pin is connected to a GPIO internally (it can be connected to multiple GPIO too) Oct 11 14:40:23 exosyst: that's a relationship that you must look up Oct 11 14:40:51 exosyst: pins are numbered by the package pins, GPIO are numbered by bank and number in bank Oct 11 14:41:10 ZiNC: that's why people do not use the web interface, they use the mail interface Oct 11 14:41:12 ZiNC, IRC seems good for chatting about projects, but what about bots that can answer noob questions? Oct 11 14:41:38 So KotH - you mean the P9.15 is what I should look up in the TRM? Oct 11 14:41:46 yes Oct 11 14:41:54 N2TOH: A very good idea. But they can't help transforming Google Groups into a usable web software. Oct 11 14:41:55 it might not be written that way Oct 11 14:42:20 It's not :-/ Oct 11 14:42:56 or a semi interegent bot that can run google foo for you and private msg it to you Oct 11 14:43:37 N2TOH: give us an AI that can parse and understand questions asked by people who neither know the problem they want to solve, have no clue what they are dealing with and use bad/brocken english to convey their "doubts" and we will feed it with the answers for the noob questions Oct 11 14:43:42 N2TOH: Better, just a phpBB/vB/IPS plugin that fetches data from Google Groups and adds it to the local db. Oct 11 14:44:17 ys Oct 11 14:44:19 yes Oct 11 14:44:22 KotH, Maybe I'm not understanding but on the BBW, I wanted to get GPIO1_7 to hook an interrupt so in my kernel module I perform a gpio_request_one((chip * 32) + pin, ..., GPIOF_IN). Do I really need to take it down to the TRM? Oct 11 14:45:19 I imagined it would be the same on the BBW - choose a gpio pin, request it and drive it. Has something changed? Oct 11 14:45:53 exosyst: if you know which GPIO it is, then you can use the same system (but with different constants) Oct 11 14:46:04 exosyst: if you dont know the GPIO you have to look it up Oct 11 14:46:07 does the BBW have the PRU cores? Oct 11 14:46:22 i dont know the bbb well enough to know what the mapping is and where it is written Oct 11 14:46:27 N2TOH: afaik no Oct 11 14:46:29 KotH, But you're saying that the gpio are connected to other gpio I should track down?? Oct 11 14:46:36 that white does Oct 11 14:46:53 the only one that doesn't is the A4Black Oct 11 14:47:06 exosyst: one gpio can be connected to more than one pin, one pin can be connected to more than one gpio. what is actually the case for the bbb i dont know Oct 11 14:47:16 exosyst: never studied the TRM closely enough for this Oct 11 14:47:42 ka6sox-away: so even the beaglboard? Oct 11 14:48:00 ay dios mio! See, understanding hardware sucks :D Oct 11 14:48:27 KotH, Beaglebone White and Black only Oct 11 14:48:53 moring ka6sox Oct 11 14:49:10 ka6sox-away: oki, thx Oct 11 14:49:16 ka6sox-away: now out with you again! ;) Oct 11 14:56:56 can the frame buffer in the BBB produce 1080 in monochrome mode? Oct 11 14:58:21 http://26-26-54.hardwarebug.org/30 Oct 11 15:20:11 KotH: http://xkcd.com/293/ Oct 11 15:34:44 ZiNC: sure, read the TRM Oct 11 15:34:52 ZiNC: it will tell you... maybe :) Oct 11 16:33:59 Hi, i own a Beagleboard Revision C3 - how can i upgrade u-boot? Oct 11 16:39:27 GeneralStupid: by replacing the files in the FAT partition Oct 11 16:39:52 dm8tbr: which FAT partition? But there is already a u-boot on my beagleboard? Oct 11 16:42:22 GeneralStupid: are you booting from SD or from NAND? Oct 11 16:42:57 dm8tbr: iam booting from SD, do i have to reconfigure my beagleboard to do that? Oct 11 16:45:07 no GS you just need to push the button near the SD card during boot Oct 11 16:47:17 I think i flashed UBoot to the NAND at ~2009 :) Oct 11 16:48:10 N2TOH: i dont want to press this button, anytime i boot up Oct 11 16:49:41 I only had to do it once Oct 11 16:49:56 it now boots from the SD card all the time Oct 11 16:50:18 Which button? "User" Oct 11 16:50:24 I only have two buttons Oct 11 16:51:01 "S2" eh only 2? what BB are you using Oct 11 16:51:13 as said above, Revision C3 Oct 11 16:51:22 S2 is reset for me Oct 11 16:51:32 white of black board? Oct 11 16:51:36 or* Oct 11 16:51:36 red Oct 11 16:52:03 sorry I don't have answerer for that board Oct 11 16:52:17 N2TOH: np, thank you anyway. Oct 11 17:05:47 generalstupid read here Oct 11 17:05:49 http://downloads.angstrom-distribution.org/demo/beagleboard/ Oct 11 17:05:58 should be newer than 2009 Oct 11 17:06:05 but not lastest Oct 11 17:07:39 woglinde: i try to install this one here https://code.google.com/p/beagleboard/downloads/list Oct 11 17:07:42 revc-4 Oct 11 17:10:51 its working again :-D Oct 11 17:11:10 this is what i did (for future problems) http://elinux.org/BeagleBoardNAND#U-Boot Oct 11 17:11:28 GeneralStupid you should update MLO too Oct 11 17:11:40 and the google code stie is rotten dead Oct 11 17:25:52 <_vicash_> hi BBB users. I am using Debian with my BBB. What is the recommended GUI desktop environment that runs efficiently on the BBB without slowing it down Oct 11 17:27:45 hi! via default the beagle board is booting from eMMC when no button is pressed. is there a way to force a boot from SD card? Oct 11 17:28:52 snomnom it boots from nand Oct 11 17:29:10 snomom overwrite mlo in nand Oct 11 17:36:32 hm removing the mlo will cause a boot from sd card but whats about the uEnv.txt file? Oct 11 17:41:29 snomnom hm dont know exactly but I think when booting from sdcard u-boot will load env from sd too Oct 11 17:51:39 hm have to check whats going on now. thanks for now Oct 11 18:25:55 <|PiP|> my beagleboard's sd card slot is damaged. is there anyway to boot off USB? Oct 11 18:26:03 <_av500_> yes Oct 11 18:26:26 <_av500_> google for pusb Oct 11 18:26:28 <_av500_> you need to boot off your PC Oct 11 18:26:38 <_av500_> it does not work off a USB stick Oct 11 18:44:01 Does anyone happen to know how to get GPIO on a BeagleBoard working in code entered by the boot ROM? Oct 11 18:45:06 huh? Oct 11 18:45:45 <_av500_> no-os I guess Oct 11 18:45:49 <_av500_> have a look at uboot Oct 11 18:45:57 <_av500_> it operates beagleboard GPIOs Oct 11 18:46:10 <_av500_> there is also TI Starterware Oct 11 18:46:21 I'm writing some code that runs when downloaded through the UART by the boot ROM Oct 11 18:46:36 I've been looking at u-boot and barebox Oct 11 18:46:50 I'm missing some detail to switch something on. Oct 11 18:47:07 <_av500_> pin muxing Oct 11 18:47:12 <_av500_> or some clocks not enabled Oct 11 18:48:27 I've enabled the functional and interface clocks for GPIO1, to try to detect user button presses. Oct 11 18:48:47 I'll look at the starterware and the muxing details. Thanks. Oct 11 18:50:07 Re: Pin muxing, should I be looking in the BB documentation or the omap35x? (or both!) Oct 11 18:54:53 OK, section 8.6.8 of teh BB manual, 7.6.2 of the omap35x TRM. Than-you. Oct 11 19:12:46 Does TI provide their own kernel API to setup the mux settings? Oct 11 19:16:48 most mux is done in DT or board codes Oct 11 19:20:23 [kernel] RobertCNelson pushed 1 new commit to 3.12: http://git.io/s2PHIQ Oct 11 19:20:23 kernel/3.12 51a5a24 Robert Nelson: 3.12: beaglebone: rebase patchset with what is in Benoit Cousson for_3.13/dts branch...

Oct 11 20:41:38 ZiNC: It seems to be stuck at 250 mhz or so I think Oct 11 20:41:54 cant find a cpu governor Oct 11 20:42:30 364.54 BogoMIPS which i'm fairly sure is way low for the bbb Oct 11 20:42:39 I'm not familiar with all that, just curious. Oct 11 20:42:44 ah ok Oct 11 20:42:47 Was it okay with the previous version? Oct 11 20:42:55 with 3.8 yes Oct 11 20:43:22 Any idea how low you can clock it? Oct 11 20:43:36 If anything, underclocking would be interesting for me. Oct 11 20:43:38 not off hand no Oct 11 20:44:07 Well, all in good time.

Oct 11 21:03:33 well darn.. Oct 11 21:10:14 guess I'll have to do some debugging of my own.. Oct 11 21:10:22 thanks all for the info though Oct 11 23:10:13 Hi, its me again. I'm using this image: http://elinux.org/BeagleBoardDebian#Demo_Image. Ive got U-Boot from 2010 installed, but it dosnt boot up Oct 11 23:16:51 what board? Oct 11 23:17:29 I dont think anything but a classic will boot with that uboot Oct 11 23:42:19 Beagleboard C3 Oct 11 23:43:01 it has got a uEnv.txt with the boot parameters. How can i tell u-boot to load the params out of the uEnv.txt Oct 11 23:44:07 uEnv.txt is for more recent uboot... boot.scr is what you're probably going to need to create Oct 11 23:44:30 is it not possible to get an recent uboot for my BB? Oct 11 23:44:46 sure Oct 11 23:45:05 but how? are there any precompiled? the newest i see was from 2010 Oct 11 23:45:18 thats the installed one Oct 11 23:45:36 there should be newer on the angstrom site if you want precompiled Oct 11 23:46:33 http://downloads.angstrom-distribution.org/demo/beagleboard/ Oct 11 23:48:38 thanks Oct 11 23:49:03 and the newer ones should normally find the uEnv.txt automatically? Oct 11 23:52:38 u-boot-beagleboard-2011.12-r4.img is offline Oct 11 23:53:04 * georgem_home looks out the window to figure out why there is stuff exploding Oct 11 23:54:51 try the uboot.beagleboard link it should be the same file Oct 11 23:58:58 oh yeah... its football season' Oct 12 00:00:12 * georgem_home wants to fireworks and shit to go off when his newly written kernel driver compiles, runs and works on the first go. Oct 12 00:03:33 so i've been trying to get my beaglebone black to boot up from sd, and am having absolutely no luck in the process Oct 12 00:05:14 lol, weren't you in here earlier today? Oct 12 00:05:24 yeah, still no luck Oct 12 00:05:35 Still trying Ubuntu? Oct 12 00:06:59 If you haven't already, try instructions from another page with a different image just to see if you can get SOMETHING to boot. Oct 12 00:08:56 i've tried several images now Oct 12 00:11:05 same SD card though? Oct 12 00:12:02 i've tried ubuntu, debian, and raspi noob... same card, but i did get a pi to boot on that card Oct 12 00:14:13 The entertainment value of this channel has plummeted since mranostay forsake us. Oct 12 00:15:59 georgem: Your driver isn't going to work on the first iteration. Oct 12 00:16:07 Unless you've written it in asm? Oct 12 00:16:42 ZiNC: heh Oct 12 00:17:29 after the first build... Oct 12 00:22:09 so... no matter what i do it seems like the little lights won't turn on for me when i try to boot from the sd Oct 12 00:22:54 i'm supposed to be holding it when i power up, right? Oct 12 00:26:34 Does your eMMC boot? Oct 12 00:27:01 yeah Oct 12 00:28:16 Then, if you push the button and it DOESN'T boot from eMMC you're doing the button pushing right :) Oct 12 00:28:34 if i plug it into my computer i can ssh into it Oct 12 00:28:48 but when i push the button with an sd card with an image on it, it won't boot Oct 12 00:29:01 then something is fucked Oct 12 00:29:15 Did you try a different SD card? Oct 12 00:29:40 no, but i used the same card to boot noobs on a raspi Oct 12 00:30:28 Are you able to see uart0 output? Oct 12 00:33:27 um... not sure Oct 12 00:33:33 youre talking about when i ssh in? Oct 12 00:34:37 no... nevermind you would know. if you have a TTL serial thingy you can hookup to it and see the u-boot output (if there is any) Oct 12 00:35:34 all i have is the cable that came with it... the usb power thing Oct 12 00:35:56 What images and instructions have you tried? Oct 12 00:37:21 http://avedo.net/653/flashing-ubuntu-13-04-or-debian-wheezy-to-the-beaglebone-black-emmc/ Oct 12 00:37:49 What size is your SD card? Oct 12 00:38:17 4 gig Oct 12 00:39:32 I'm trying to find the setup_sdcard.sh so I can take a look at it. Oct 12 00:40:41 alright Oct 12 00:40:59 i'm also redoing it... gonna try booting the raspi on debian instead of noobs so i know the image works Oct 12 00:43:11 "sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot bone_dtb" looks a bit suspicious. I would have expected "sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot boneblack_dtb" Oct 12 00:45:52 well, i can certainly try that Oct 12 00:47:20 mariner: look at these instructions also... http://circuitco.com/support/index.php?title=Ubuntu_On_BeagleBone_Black Oct 12 00:48:15 so i asked about this earlier, and people seemed to think it didn't matter Oct 12 00:49:15 but this is saying i need the 5v external power source thing Oct 12 00:49:20 so i should get one of those? Oct 12 00:49:43 good question Oct 12 00:50:08 I would suggest you get one no matter what Oct 12 00:50:50 But I can't tell you with any certainty whether its impossible to do what you're doing without one. Oct 12 00:50:50 also, no point in getting started before i have the ethernet hookup? Oct 12 00:51:27 I'm not sure why it says that Oct 12 00:52:33 but it should have been able to boot from the card on the usb... right? Oct 12 00:52:48 wait USB what? Oct 12 00:53:14 what is this about USB? Oct 12 00:53:15 the usb to microusb cord that came with it Oct 12 00:53:24 thats how i've been powering it up Oct 12 00:53:40 oh right... Oct 12 00:53:43 and, when i have the board connected to my laptop i can ssh into the bbb Oct 12 00:53:57 thought you meant booting from a USB sd card adapter or something. heh Oct 12 00:54:07 no no, i'm dumb, but i'm not quite that dumb Oct 12 00:54:08 close Oct 12 00:54:20 * mariner is rather dumb, but is trying to learn Oct 12 00:54:40 You sound like you're doing fine actually. Oct 12 00:54:50 i fake it well ;) Oct 12 00:56:14 the only other thing i can think of is that the board itself might be bad Oct 12 00:56:30 Its possible the BBB is unable to source enough power to boot off the SD card. Oct 12 00:56:35 though the fact that it will boot from the eMMC makes me mostly doubt that Oct 12 00:58:07 You said none of the lights come on when booting from the card? Oct 12 00:58:43 correct... the power light comes on, but the bank of 4 on the other side of the ethernet plug Oct 12 00:58:48 doesn't light up at all Oct 12 00:59:51 you hold the user/boot right? Oct 12 01:00:05 Seems some other people had similar problems: https://groups.google.com/forum/#!topic/beagleboard/UBuACCD3OG4 Oct 12 01:00:23 thats the button on the opposite side from the sd slot, right? Oct 12 01:00:23 im actually curious, i tried flashing the beagle from the sd card and it seemed to have worked, but now it won't boot without the sd card inserted Oct 12 01:02:31 I don't know the sequence for how the LEDs are turned on. If someone of them are turned on by u-boot and you're getting nothing its not getting very far Oct 12 01:02:43 some* Oct 12 01:03:54 yeah.... it just completely locks out Oct 12 01:08:59 is there any docs on the boot process? Oct 12 01:09:22 the boot process is pretty simple, what do you want to know about it? Oct 12 01:09:31 well the first thing Oct 12 01:09:35 somehow i managed to flash the board Oct 12 01:09:38 with an sd card Oct 12 01:09:45 but now it wont start up without the sd card isnerted Oct 12 01:11:17 What did you flash it with? Oct 12 01:11:47 first i tried the emmc flasher Oct 12 01:11:49 image Oct 12 01:11:54 which loaded up the console angstrom Oct 12 01:12:07 but then i flashed it with the default Angstrom with gnome image Oct 12 01:13:20 the gnome angstrom image also being the emmc flasher variant Oct 12 01:13:25 with BBB-eMMC in the package name Oct 12 01:13:39 And you get no indication that it's doing anything on boot? Oct 12 01:13:53 woah this is pretty interesting.. ddr3.. I'm newb :) Oct 12 01:13:56 i'm running fedora rawhide x86_64, ran mkdevrule.sh which created a 73-beaglebone.rules, but link in Step 3 of Get Started page doesn't seem to work on both Firefox and Chrome Oct 12 01:14:02 sec Oct 12 01:14:05 two of the leds just blink Oct 12 01:15:59 the EMMC light stays fully lit and heartbeat led pulses Oct 12 01:16:08 but the gnome desktop never loads Oct 12 01:16:25 this is so weird… how hardware programming is shifting to javascript? Oct 12 01:17:41 javascript provides you control over some "dumbed" down functionality but theres still alot of work thats done in C Oct 12 01:17:50 for the javascript to work :P **** ENDING LOGGING AT Sat Oct 12 02:59:59 2013
