May 08 03:51:32 did you create the 3d model yourself? May 08 04:14:15 mrpackethead yes i am going to machine that May 08 04:14:24 i made the model May 08 04:14:33 what mateirals? May 08 04:15:29 probably 6061 May 08 04:15:42 whatever i can find though May 08 04:16:38 i might pocket out the top, put some kinda design there May 08 04:16:58 this is just rough model i will finish it later i am tired May 08 04:17:26 it takes 4-40 Phillips machine screw May 08 04:18:15 the bottom machine screws will be thread locked on (purple loctite) May 08 04:18:41 so the top ones can be loosened without the standoffs turning May 08 04:19:49 for easy access May 08 04:19:52 :D May 08 06:23:22 hello May 08 06:23:50 anyone here ? May 08 06:28:06 no May 08 06:53:25 hello May 08 07:05:10 Hi All, I have BBB, I am connected to BBB using ethernet. I have given fixed IP through server for board mac address. Now as I am already in BBB. I have installed linux-kernel header and kernel devel. I want to do some changes in my mmc driver. May 08 07:06:02 for this do I need download and z image. Any suggestions are welcome. I am new to kernel programming. I have tried hello kernel code building on board. able to insert as module for hello kernel code. May 08 07:07:49 well whats the problem? May 08 07:08:18 How to get mmc driver source and build kernel. May 08 07:08:29 mmc driver source is in the kernel. May 08 07:08:29 root@beaglebone:~# uname -a May 08 07:08:30 Linux beaglebone 3.8.13 #1 SMP Thu Sep 12 10:27:06 CEST 2013 armv7l GNU/Linux May 08 07:08:30 root@beaglebone:~# May 08 07:08:34 usual build rules apply. May 08 07:08:46 alternatively, you can just crossompile May 08 07:08:51 sorry but how to get mmc source and compile it. May 08 07:08:54 installation will depend on the distro running May 08 07:09:08 I am running angstrom May 08 07:09:49 well then get the kernel source tree. May 08 07:10:26 angstrom kernel workflow is well described May 08 07:10:43 http://beagleboard.org/linux May 08 07:10:57 is this link steps will help to checkout source May 08 07:11:31 * tbr wonders why sachin wants to rebuild the kernel if he has no experience with it. May 08 07:11:47 on a first glance this page looks good May 08 07:12:59 so with this page I will download source code and I will able to build specific module , am I right ? May 08 07:13:35 sachin: no you are wrong. this page gives a person that knows how to do things the necessary, beagle-specific knowledge May 08 07:14:05 that does *not* necessarily mean that it is enough for *you* May 08 07:14:35 sachin: you should really learn how to configure and build a kernel basically first. May 08 07:15:03 hi May 08 07:15:12 mooo May 08 07:15:22 Ok Understood. Any link or any suggestions are welcome. I have alredy tried to browse lot of link but all tries to explain zImage build process not any specific kernel module. May 08 07:15:41 sachin: because it does not work like that. May 08 07:15:44 because that goes hand in hand May 08 07:16:02 sachin: you always have to build all together. the modules have to fit the zImage. May 08 07:16:32 so: really learn the basics first! May 08 07:16:38 Ok I tried helloKernel which just print on load when i insmod hello.ko May 08 07:17:01 so through similalrly I will try and build mmc driver ko May 08 07:17:17 *sigh* May 08 07:17:20 well whatever. May 08 07:18:35 sachin: if you don't want help, that's fine, just don't ask for it. May 08 07:19:46 Please I need help. May 08 07:20:17 Ok so as per your suggestion I will download linux kernel source for BBB May 08 07:20:28 and then try compile whole together. May 08 07:20:35 then do what we told you. get the complete kernel sources and learn how to build it all together. then, learn how to run it. May 08 07:22:29 Ok sure. Lets say I have build it all together. Then what need to install on board. So whole kernel together or how it will be. May 08 07:22:51 *sigh* May 08 07:23:22 just make sure you can buld/run your own zImage, please. May 08 07:24:07 Ok Sure. Thanks for help so with help of linux kernel source I need to build and final output will be zImage. which I need install. May 08 07:43:58 @tbr, sorry for late reply. I dont want to build kernel. main intention is add some feature in mmc driver. May 08 07:45:39 sachin: yes and we told you how to do that. you ignored it and you continue to have a problem. May 08 07:47:05 I am not sure which problem you ar talking but LetoThe2nd gave me information about download kernel source and now I am checking out from http://beagleboard.org/linux May 08 07:47:37 we told you to search for the angstrom linux kernel workflow May 08 07:48:19 somehow I missed it, I will search for kernel workflow as well. Thanks for reminding. May 08 07:51:47 Any idea about how much size of beagleboard/kernel. May 08 07:52:00 It is getting downloaded , May 08 08:37:09 Hello ! Can I disable VDD_3V3EXP on my BB ? May 08 08:38:00 Stee: I don't think so, but the schematics will certainly tell you. May 08 08:39:25 Ok :( I took a look, but i didn't find how May 08 09:10:11 Hi LetoThe2nd, I have download linux kernel and executed following steps. now it is compling. May 08 09:10:22 git clone git://github.com/beagleboard/kernel.git && cd kernel May 08 09:10:23 git checkout 3.8 May 08 09:10:23 ./patch.sh May 08 09:10:23 downloaded am335x-pm-firmware.bin from http://arago-project.org/git/projects/?p=am33x-cm3.git;a=tree;f=bin May 08 09:10:23 copy it to kernel/firmware May 08 09:10:25 cp bin-am335x-pm-firmware.bin /home/sachin/greenzone/source/kernel/kernel/firmware May 08 09:10:27 cd kernel May 08 09:10:29 cp ../configs/beaglebone .config May 08 09:10:31 sudo apt-get install gcc-arm-linux-gnueabi May 08 09:10:33 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage dtbs May 08 09:12:01 now how to run uImage on BBB May 08 09:55:23 shawnbon206_: i have multiple, and bunches of mics May 08 09:56:46 Hello every1 May 08 09:57:14 hav run into a bit of a issue.. my BBB refuses to boot May 08 09:57:44 it gets stuck at searching for Btrfs while booting.. May 08 10:02:17 ? May 08 10:03:50 since when? running which image? May 08 10:14:41 I have built beagleboard kernel using gcc-arm-linux-gnueabi by installing (sudo apt-get install gcc-arm-linux-gnueabi), will it work or I need to install toolchain like angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2 May 08 10:14:52 I have angstorm on my BBB May 08 10:20:05 where u compiling in? May 08 10:20:32 where u compiling from? May 08 10:21:25 sachin: u can use default apt's arm-gcc May 08 10:21:36 I am compiling on ubuntu 13.10 May 08 10:22:06 Ok Thank you so default installed sudo apt-get install gcc-arm-linux-gnueabi May 08 10:22:11 is enough right . May 08 10:22:35 yes May 08 10:22:51 Thanks. May 08 10:56:11 Hi LetoThe2nd.. I have been trying with a lot of Images May 08 10:56:32 Ubuntu, debian, angstrom, cloud9... both SD and eMMC Flasher ones.. May 08 10:56:45 i just get the hearbeat on USRLED 0 and then kernel panic May 08 10:59:28 Rahul_: 1) keep things in channel 2) i am busy otherwise now. May 08 10:59:59 Rahul_: 1) keep things in channel 2) i am busy otherwise now. May 08 11:01:16 Okhay May 08 11:05:00 BBB Stuck while booting.. I have a Hearbeat on USR0 constant USR3 LED's and Any suggestions? May 08 11:27:11 ? May 08 11:27:46 Rahul_: how do you know it's stuck? May 08 11:27:56 Rahul_: do you have a serial cable attached to see what it's doing? May 08 11:35:24 Anyone know what is planned for BBB rev. d? if there will be such a ting May 08 11:38:04 rev c is just about to ship, no real info on rev d May 08 11:50:19 on angstrom I could run something like "systemctl disable gdm" to disable X starting by default. I can't find any reasonable service to disable on the debian image. Any ideas? May 08 12:44:47 hi May 08 12:45:18 I'd like to build a BBB from scratch May 08 12:45:41 but I am in doubt May 08 12:45:42 get the files and get crackin' then May 08 12:47:17 if i assemble a BBB hw, i need to flash something to start May 08 12:47:35 ROM i mean May 08 12:48:08 no May 08 12:48:16 the ROM is in the CPU May 08 12:48:58 but if i assemble an power, how can know howto load system May 08 12:49:33 the ROM code knows May 08 12:49:46 i assemble, put the sd in and all ok? May 08 12:49:59 who put the rom code? May 08 12:50:03 if you made no mistake, yes May 08 12:50:07 TI put it May 08 12:50:28 it's explained in the TRM, isn't it? May 08 12:55:13 im lookin for trm May 08 13:11:59 av500: where can i find trm? May 08 13:23:40 seriously?

May 08 13:30:35 about 447 mio. people according to wikipedia May 08 13:30:54 Anyone know how I can emulate a BBB with QEMU? May 08 13:33:18 hello someone speak spanish? May 08 13:34:52 http://www.teachertube.com/viewVideo.php?video_id=197025 May 08 13:36:31 i have a beagle 4 years old with sintoms of beagle pain syndrome someone has a dog with this discease? May 08 13:37:00 teobauwer: more people discuss http://beagleboard.org here than real-life beagles May 08 13:37:36 teobauwer, http://beagleboard.org ... this channel is not about dogs May 08 13:37:47 ok sorry May 08 13:38:09 hope your dog gets better though May 08 13:47:12 thanks May 08 13:51:22 Hello everyone, I have a quick question. I am gathering research on starting a alarm/home automation project. My current question is, Would it be better to do two projects, one beagle board for each section, or can I run both projects off of one board? May 08 13:59:31 you'll probably need to explain more about the two sections before anyone can avaluate that May 08 14:03:12 seifres: you can put as many "projects" onto one bbb as you want, as long as you have enough resources (memory, cpu, i/o) May 08 14:03:28 seifres: but depending on the kind of projects it can make sense to seperate them May 08 14:42:48 Hi there! May 08 14:46:06 I've been messing with a BBB all week triying to stream over tcp a logitech 160 webcam(uvcvideo) with gstreamer with no success... May 08 14:46:50 the gstreamer pipe i'm using is : gst-launch v4l2src ! video/x-raw-yuv,framerate=30/1 ! jpegenc ! multipartmux ! tcpserversink host=127.0.0.1 port=5000 May 08 14:47:19 this works properly at my x86 ubuntu but nothing happens when i try it on de BBB May 08 14:47:23 any thoughts? May 08 14:47:31 javier_: not a gstreamer expert by any means, but where is it failing? can you narrow it down by using a gstreamer testsource? May 08 14:48:17 it works ok with the "videotestsrc" element May 08 14:50:53 and when I use the same pipe with the v4l2src element it seems as it starts ok but nothing happens and nothing is streamed May 08 14:51:44 and same webcam works on the PC? May 08 14:51:56 yep May 08 14:53:00 i've tried other uvcvideo webcam with the same results May 08 14:53:27 are you sure the kernel module is loaded? May 08 14:54:22 lsmod lists uvcvideo and videobuf2_vmalloc used by uvcvideo May 08 14:57:20 the green led of the camera even turns on May 08 15:00:37 how does the CPU load look when you run gstreamer? May 08 15:03:17 0% for the "v4l2src" element 60% for the "videotestsrc" element May 08 15:04:10 anything in dmesg? May 08 15:05:02 nothing special May 08 15:07:04 i've tried with another uvcvideo webcam (which don't hotplugs at the BBB ) with the same results May 08 15:07:25 and both webcams work ok on a x86 ubuntu... May 08 15:14:00 with the other webcam i get a bunch of errors of "Got unexpected frame size of xxxxx" and the stream stops May 08 15:18:07 tried to ask in #gst? May 08 15:18:57 nop... thought it was a BBB related problem and give it a try with you guys May 08 15:19:05 anyway... thanks for your help! May 08 15:20:36 #gstreamer May 08 15:24:22 javier_: it might be beagle related, but we are no gst experts May 08 15:27:53 I imagine... anyway it's a marvelous piece of hardware... hope it keeps evolving and improving May 08 15:54:20 help me out here folks. i am designing a case. its meant to leave the sides open for access to the gpio and buttons. i need help on the asthetic parts. for example, is the chamfer on the contour too agressive? https://drive.google.com/folderview?id=0B0XzvqNi9HIdM0dZS3VHVDlwQWM&usp=sharing May 08 15:55:28 its going to have 4-40 machine screws in it May 08 15:56:27 with the bottom ones loctited in May 08 16:04:54 <_av500_> we need to decide on a color first! May 08 16:05:03 <_av500_> i must be muave! May 08 16:05:22 youre _av500_ May 08 16:05:34 <_av500_> it* May 08 16:05:34 <_av500_> darn May 08 16:05:36 hi guys May 08 16:06:01 Do you guys know if the beaglebone is being discontinued? May 08 16:06:08 the bikeshed must be blue! all bikesheds are blue! May 08 16:06:13 oh i can Anodize it May 08 16:06:19 having hard time to get hands on large quantities of bb's May 08 16:06:34 Guest35689: Yeah, because everyone else is trying to get their hands on large quantities of BB's.. May 08 16:06:40 knock it off :P May 08 16:06:59 why is there such a shortage? May 08 16:07:10 we built it into our energy monitoring product, we need like 100x May 08 16:07:15 the trouble is that it's priced so low, they can *only* use the cheapest manufacturing, there's no slack to ramp up to a higher-volume mfr because it would cost a smidge more May 08 16:07:22 and the only place i can find it is on ebay from shenzhen May 08 16:07:31 umm, did you read the thing about contacting circuitco before using it in a commercial product? May 08 16:07:37 ok, so its not been discontinued, i heard some i2c problmes May 08 16:07:56 no, contacting circuitcco? May 08 16:08:12 as in contracting them to specifically guarantee us batch sizes? May 08 16:08:21 (Thanks for the help btw) May 08 16:08:26 Guest35689 can you please change your nick May 08 16:08:30 sorry May 08 16:08:54 to something that isn't taken :) May 08 16:09:01 jeez, how do i do that.. May 08 16:09:07 /nick nick May 08 16:09:51 nice, thanks May 08 16:09:53 could i ask whether the i2c problem has anything to do with the potential shortage? May 08 16:11:46 there's no shortage May 08 16:11:56 it's just that people are buying a fuckload of boards May 08 16:12:08 so when a shipment comes in, it goes to fill the back-orders first, and they never sit around in stock May 08 16:12:14 ok ok, so still being produced ... gotit May 08 16:12:16 simply place a back-order, and you'll get your boards. simple as that. May 08 16:12:29 you've got to get in line in order to get to the front of the line May 08 16:12:32 ok got it. is there any way to buy directly from circuitco May 08 16:13:31 you'd have to email them, but I'd guess not, that's what distributors are for, after all May 08 16:13:54 unless you're talking many thousands of units like any other distributor May 08 16:14:29 for 100, umm, no, just get 'em from $ResellerDuJour May 08 16:17:19 (btw I'm just a lurker and resident curmudgeon, my word should be taken as just that -- blatherings of some dude on IRC not associated with the project, but, some dude who's heard all this before.) May 08 16:21:06 appreciate the answers May 08 16:21:08 what is $resellerdujour May 08 16:21:08 or who? May 08 16:22:34 thats a variable May 08 16:22:39 $reseller May 08 16:23:02 dujour means popular May 08 16:24:18 do you have a specific recommendatin? May 08 16:25:54 du jour is actually translated as "of the day" May 08 16:31:28 can anybody suggest a good reseller of beaglebones who has good stock availability and ships to EU? May 08 16:32:48 good stock availability is kind of a problem with the bbb at the moment May 08 16:32:53 they are selling way too fast May 08 16:33:04 but you can try farnell, they seem to get them regularly. May 08 16:33:07 good stock availability would make me very suspicious May 08 17:14:31 Hi, any advice on how I could emulate a BBB with QEMU? May 08 17:15:10 Work has two BBB's, and supposedly they had a to pay a premium for them. May 08 17:15:36 varad: Uh, get a QEMU target for ARM? May 08 17:19:10 varad: do you specifically need to emulate a BBB, or just any arm board? May 08 17:19:32 agmlego: I can't find am335x cpu model in QEMU's cpu support list. May 08 17:19:40 vagrantc: specifically the BBB May 08 17:20:51 varad: Do make one. May 08 17:20:54 *So May 08 17:21:19 Or, just buy a bone. May 08 17:21:21 ;-P May 08 17:21:30 Probably cheaper and faster than trying to emulate. May 08 17:22:23 agmlego: that's the issue! no bones in stock anywhere. I'm stuck... May 08 17:22:44 varad: Did you read the channel topic?> May 08 17:23:59 varad: No one shows stock because more people are wanting bones than can be produced. Stock means bones are sitting idle in warehouses, which is boring and not useful. Buy a bone from a distributor and wait like everyone else; you cannot get to the front of the line unless you are in the line. May 08 17:25:19 agmlego: I know. Already ordered, waiting. I have some stuff I need to test, and emulating it would be my best option for right now. May 08 17:25:21 varad: allegedly this contains support for it: https://git.linaro.org/?p=qemu/qemu-linaro.git May 08 17:25:51 oh wait, that's just beagleboard May 08 18:11:44 hello May 08 18:12:13 can you read me? May 08 18:12:29 hello? May 08 18:12:49 maybr May 08 18:13:02 ask and we may tell May 08 18:13:11 ok shawnbon206 May 08 18:13:20 hows it on cloud 9? May 08 18:13:21 i have a problem with my beaglebone black May 08 18:13:33 my beaglebone black is near of me May 08 18:13:42 and normaly i conect using ssh May 08 18:13:44 too close? May 08 18:13:46 help_cloud9: please be specific and patient May 08 18:13:50 far May 08 18:13:51 sorry May 08 18:13:54 far May 08 18:13:59 too far. May 08 18:14:01 yes May 08 18:14:02 too far May 08 18:14:10 only can conect with ssh May 08 18:14:16 help... slow down, press enter fewer times May 08 18:14:31 so, my bealglebone black is a datalogger May 08 18:14:43 and now the memory is full May 08 18:14:52 and i canĀ“t conect with ssh May 08 18:15:24 oh i see May 08 18:15:30 it is posible delete the memory of a determinate folder using cloud9? May 08 18:15:57 only can conecto to beaglebone black using cloud9 May 08 18:16:43 the answer is dificult? May 08 18:17:45 so the storage is filled up and you cant ssh to it. i dont have a bbb yet, but the storage is on the same partition as / or what? May 08 18:18:01 ssh_exchange_identification: Connection closed by remote host May 08 18:18:16 yes May 08 18:18:21 is in the same partition May 08 18:19:30 if i put ip board with :3000 in firefox, i can enter in cloud9 May 08 18:19:52 i only have this alternative May 08 18:20:53 you can run scripts in there to do all sorts of stuff. May 08 18:21:37 you might have an issue with your ssh key. There have been some fixes shared on-line.... I'll grab a link for you. May 08 18:21:57 thank you jkrinder May 08 18:22:32 the problem began went the storage fill May 08 18:22:52 help_cloud9: https://groups.google.com/d/msg/beagleboard/Ya2qE4repSY/ihEP5n2BNGUJ May 08 18:23:05 you can see each 'exec' line runs a linux command May 08 18:23:30 The new cloud9 in the Debian images is a LOT nicer.... with a real terminal directly in the browser. May 08 18:24:58 is RT5370 WiFi dongle compatible with the BeagleBone Black? May 08 18:25:03 https://docs.c9.io/terminal.html May 08 18:25:26 awesome May 08 18:25:54 thats nice i need to set something like that up on my pi May 08 18:26:46 thank you jkridner May 08 18:27:01 i think that i can to update to debian May 08 18:27:02 ... May 08 18:28:35 youll want to make your logs rotate next time May 08 18:29:54 and if possible keep in separate file system than / May 08 18:31:16 you can work out of a "disk image" May 08 18:31:23 which mounts loopback May 08 18:31:44 as an alternative to partitioning May 08 18:35:15 alex001: Are you the same alex who was asking about the quadcopters before? May 08 18:50:20 hello, I am using debian 3.8 on my beaglebone, I installed a fresh cloud9 clone and now having trouble launching it automaticly, anyone has any experience on this? May 08 18:50:35 trevize: why a fresh clone? May 08 18:50:41 receiving Cannot GET / on browser May 08 18:51:20 because I had issues with the old one May 08 18:52:07 trevize probably easier to re-image or reinstall using Robert's steps than to try to debug a different version. I've had headaches debugging various versions. May 08 18:52:22 they don't always leave their tree in an easy-to-run state. May 08 18:53:17 hmm I see, so u recommend going back to the stock one May 08 18:53:29 could you link robert's steps May 08 18:54:49 http://cheezburger.com/7720007936 May 08 19:12:48 @jkridner out of the cl9 versions you tried which onw was the most stable? May 08 19:13:17 trevize: the one on the Debian image that they don't have on their public tree yet. :( May 08 19:13:34 :) thanks, May 08 19:13:45 trevize: http://github.com/beagleboard/image-builder May 08 19:14:17 * jkridner wonders about the issues you had May 08 19:14:34 trevize: latest images at http://beagleboard.org/latest-images May 08 19:15:16 well copy / paste didnt work, debug never started at first run. I had to stop & re-run multiple times before I could debug May 08 19:15:45 but copy/paste was the major reason, I couldnt find a solution May 08 19:19:34 thanks for your help btw May 08 19:22:50 jkridner are you my god May 08 19:23:09 thank you, now i can do ssh May 08 19:23:30 only i use the instruction exec() and the command rm May 08 19:23:39 trevize: sure, I do copy-paste all the time from my mac. May 08 19:24:08 trevize: are you using the one that was packaged with Debian or the older one? May 08 19:24:20 trevize: huge difference in stability. May 08 19:24:49 other question May 08 19:24:54 is beter debian? May 08 19:25:03 than amstrong? May 08 19:25:44 They are different. May 08 19:26:07 Angstrom is highly flexible for professionals looking for just the right image. May 08 19:26:18 Debian is easy and more familiar to the majority of users. May 08 19:26:38 Angstrom is more customizable. May 08 19:26:44 Debian has more pre-built packages. May 08 19:26:52 Angstrom is buggy as shit. May 08 19:26:59 Debian is the universal operating system. May 08 19:27:07 hi agmlego May 08 19:27:25 yeah I could copy/ paste but then not sure what happened but copy/paste was gone, I was using this : debian-7.4-2014-03-04 May 08 19:27:53 jkridner: Hey. May 08 19:28:09 agmlego: I'm headed to a node.js meetup in Detroit tonight. May 08 19:28:22 and there are more resources on debian May 08 19:28:28 jkridner: Neat. May 08 19:28:41 * jkridner tries to draw people to the node.js dark side May 08 19:28:44 jkridner: I am probably pulling another 12-14-hour day today. :-/ May 08 19:29:25 trevize: get to the 2014-04-23 image. May 08 19:30:12 downloading atm May 08 19:32:45 the main problem with that image is that there is very little space left once u flash it May 08 19:33:37 Easy enough to fix that. May 08 19:35:01 how? May 08 19:35:48 lat time I removed gnome packages as to get some space May 08 19:37:11 THat would be a big one. May 08 19:37:20 THe other is...the microSD card slot. May 08 19:38:18 :) May 08 19:38:59 But yeah, there is a lot of stuff in a base install like that that you can get rid of. May 08 19:39:27 i love the raspbian headless install method May 08 19:39:59 you only get the bare minimum required to boot, ssh in, and get stuff from apt-get May 08 19:40:10 do you have anything else in your mind that would probably not needed? May 08 19:40:22 Yeah, that sounds like a standard debian ssh-enabled netinstall. May 08 19:40:37 trevize: Not until I know what the installation is being used for. May 08 19:41:48 robotic application , no gui needed May 08 19:42:07 running on wifi May 08 19:42:19 But honestly? run aptitude and wander through the categories, reading the description of things, and setting things to uninstall or purge. May 08 19:42:40 localepurge is a useful package to install too. May 08 19:43:09 apt-get purge && apt-get autoremove --purge May 08 19:43:13 You know, the same way you streamline any installation base. May 08 19:43:26 shawnbon206: Right, that works if you know the package. May 08 19:43:36 I tried aptitude, takes ages to browse through for very small packages May 08 19:43:46 Well, yeah. May 08 19:44:04 I never said it was a fast process, especially on a slow machine like the bone. May 08 19:44:25 THis is why my first suggestion was to use the microSD card slot. May 08 19:44:56 agmlego does locale purge remove tz stuff too? May 08 19:45:28 No idea. I bet the project documentation says one way or another though. May 08 19:46:05 I want to keep the slot free for mounting stuff :) May 08 19:46:30 trevize: Sure. You also have not mentioned what you want all this free space *for*. May 08 19:47:36 http://manpages.ubuntu.com/manpages/precise/en/man8/localepurge.8.html May 08 19:48:54 oh deborphan May 08 19:49:06 theres another tool May 08 19:49:12 well I needed it to install a few networking tools, logs & stuff. I dont have a precise project in my mind, just testing how things can be done. last time I tried to update cloud9, I ran out of space May 08 19:49:27 deborphan is only useful if you have orphaned packages. A new installation will not. May 08 19:49:43 trevize: Sure, because 2GiB is small. May 08 19:50:28 yeah, thats why I am waiting for the 4gb rev May 08 19:50:45 Or just change the part out yourself. May 08 19:52:01 u mean the sd or the emmc? :P May 08 19:52:11 The eMMC. May 08 19:52:42 IIRC, it is a discrete component on the board. Just pull it and put a bigger one on. May 08 19:55:27 Of corse I'd change it if you try it on your board first :P May 08 19:55:56 Not like they are that expensive, and i have a hot air station. May 08 19:56:06 Matter of a few minutes. Might even have the right part in stock. May 08 19:56:09 Next! May 08 19:56:41 http://heisdnast.files.wordpress.com/2012/08/goatse-mobile.jpg May 08 19:57:04 /kick shawnbon206 Inappropriate. May 08 19:57:04 ok shoot a video on youtube and I'll click your ad link 1000 times May 08 19:57:17 trevize: Maybe sometime when I have free time. May 08 19:57:18 think thats a Photoshop? May 08 19:57:30 trevize: But I will point out, I never boot from eMMC. May 08 19:58:40 what do you think about the sd power usage then? May 08 19:58:55 Negligible? May 08 19:59:12 on mobile devices running os on sd has impact on battery usage May 08 19:59:33 Pretty sure if you are using the bone in an application where the amoun t of power an SD card draws is critical, you should not be running Linux or a scripting language on it. May 08 19:59:48 Just saying. May 08 19:59:49 thats true May 08 20:00:02 Also, bigger battery. May 08 20:00:43 Especially if you are thinking about robotics...your motors and WiFi are the power draw that matter. May 08 20:01:14 (The only rule of optimization is profile first. Premature optimization is not useful, relevant, or effective) May 08 20:01:36 AKA, stop optimizing until you know what to optimize. May 08 20:01:49 you are right :) May 08 20:02:25 I am not optimizing stuff I still have ways to go May 08 20:02:39 just asking your opinion as not sure about the power drainage May 08 20:02:50 * agmlego 's degrees are focused around embedded systems and controls. ;-P May 08 20:03:01 for now I have 2x 3.7v 2200 liion batteries May 08 20:03:09 Series or parallel? May 08 20:03:18 series May 08 20:03:44 OK, and a decent high-efficiency switching regulator for the 5V to the bone? May 08 20:03:54 I have an ubec May 08 20:04:03 it is running fine May 08 20:04:04 I like the LM2576 or similar from National/TI. May 08 20:04:07 ubec? May 08 20:04:08 not heating too much May 08 20:04:49 http://www.hobbywing.com/uploadfile/Multi-Angle/ACC/UBEC/UBEC-3A-1.jpg May 08 20:05:35 I have tried some voltage regulators but they were heating as hell, consumes too much power May 08 20:05:55 Yeah, that is a switcher. May 08 20:06:32 Linear regs are the wrong approach, in general really, but especially with that big a voltage difference and when power consumption matters. May 08 20:06:38 it has a jumper u can set it to 5 or 6 v May 08 20:06:38 And with the current draw you expect. May 08 20:06:52 Not switcher like that. THat is just adjsutable output. May 08 20:07:06 Switcher as in switch-mode power supply. May 08 20:07:38 It changes voltage level by high-speed interruption, basically PWM-ing the input to make a stable output. May 08 20:10:08 it does the job well :) May 08 20:10:38 Probably upwards of 80-90% efficient. May 08 20:10:48 Although China. May 08 20:10:55 So might be as low as 60%. May 08 20:11:01 Still better than linear. May 08 20:11:29 I burnt my finger on a linear one May 08 20:12:03 as the total output of my batteries at full charge is about 8.4 V May 08 20:12:34 Yeah, Li-Ion float is around 4.2V, so 2S is 8.4V. May 08 20:13:00 the difference goes to heat and you are in trouble if you dont have a heatsink May 08 20:28:10 Yes, I am aware. ;-P May 08 20:28:18 And, that is power you are wasting as heat. May 08 20:38:47 I have decided to go with your method and run it on sd May 08 20:39:27 ok I have a 8gb sd, donwloading a 2gb sd version atm. which means I can use the remaining 6 gb only if I partition it right? May 08 20:44:36 just need to expand the partition May 08 21:18:02 trevize_: Yeah, it is trivial to expand the partition and filesystem. Just, not from the booted image. May 08 21:18:53 trevize_: Use a different computer--if you do not have a machine natively running Linux, download one of the GParted live images and boot a machine from it with the SD card in a reader, and expand the partition and filesystem there. May 08 21:26:59 hi May 08 21:32:03 hi all May 08 21:32:35 I am so interested in becoming a distributor of beaglbone in morocco May 08 21:36:47 Awesome. YOu should contact circuitco directly, or talk with jkridner. May 08 21:37:29 technobis: I'd forward you to sales at the 'ol circuit the co... m even May 08 21:38:06 technobis: they haven't been taking on distributors lately until they catch up with demand. May 08 21:38:10 but, they are ramping production fast. May 08 21:39:49 technobis: you can still drop me an e-mail anyway May 08 21:41:03 can you pl give me your email May 08 21:41:36 Thanks all for your help May 08 22:57:58 anyone know of any good channels for m2m/iot questions? i'm interfacing a bbb to gsm/gprs cellular module. thanks! May 08 23:13:21 trevize_: Yeah, it is trivial to expand the partition and filesystem. Just, not from the booted image. May 08 23:13:30 its super trivial May 08 23:13:42 theres even a script that makes it even easier May 08 23:47:34 Has anyone been able to get the SPI to work on BBB May 08 23:48:11 I am trying to use SPI0 and it appears that I have the CS, Clock, to work but the MOSI seems to be behaving weird May 08 23:48:30 i.e. the MOSI pin is outputting when BBB idle May 08 23:50:03 spi works fine May 08 23:50:21 you should probably consider setting spi mode May 08 23:53:22 I changed the SPI mode and no luck May 08 23:58:18 well without seeing what you're doing May 08 23:58:20 its hard to say May 08 23:59:05 https://github.com/notnyt/beaglebone#spi ezmode spi May 09 00:05:10 BeagleBot! May 09 00:07:50 Do I need to change the pin multiplex to use SPI? May 09 00:15:06 .... yes May 09 00:15:24 or use a lib that does it for you May 09 01:43:15 you can't get stuck in analogue May 09 01:44:32 wat May 09 02:04:50 hi guys i had a question. If I am not using external power am I able to power an apc220 rf module from the p9 header? May 09 02:10:22 should be able to hook it to vdd5v May 09 02:26:04 nyt-, do you think i will need a logic level converter to use it with the beaglebone black? I know it works fine with an arduino May 09 02:41:18 Are there any known issues with A6A? Or was it upgraded only because AM3359's unavailability? May 09 02:54:22 unavailability **** ENDING LOGGING AT Fri May 09 03:00:01 2014
