**** BEGIN LOGGING AT Fri Jan 09 02:59:58 2015 Jan 09 03:15:12 * yates chomps at the chocolate truffles Jan 09 03:45:30 does the computational complexity of the spectral estimation algorithm that uses minimum relative entropy exceed the capabilities of a beaglebone black? Jan 09 03:50:40 Have you tried it yet to see? Jan 09 04:43:34 agmlego: yes. Jan 09 04:47:29 I have some teensy's, a couple arduino's and a raspi, I'm thinking of taking a look at BBB, I came here to pique my curiousity. Jan 09 04:48:20 Specifically for interfacing with Lego, I saw a project on Kickstarter that has a board for the BBB (is it okay to call it BBB?) Jan 09 04:49:49 it is indeed encouraged Jan 09 04:51:50 I see it has a kernel already on it, so my next question is that can you completely bypass the built-in kernal and use the OS off an SD? Jan 09 04:52:38 not built-in per se, it has emmc that you can put whatever you want on (ships with debian), you can also boot from SD, USB, or serial Jan 09 04:54:41 Ahh, cape, that's the term I was looking for. Arduino uses shield, I knew that wasn't right. Jan 09 04:55:02 same idea Jan 09 04:56:01 Best place to pick one up? I get most of my drugs from Sparkfun. Jan 09 04:57:20 at the moment, whoever has one in stock :P there are two different makers out there right now, circuitco (out of stock most places at last count) and ones branded by element14 ... i have an element14 bbb from adafruit Jan 09 04:57:54 they are identical. Jan 09 04:58:16 SF has 463 in stock Jan 09 04:58:20 the element14 bbb does not have a little doggie screened on the pcb, that is its biggest drawback Jan 09 04:59:05 Oh, it takes a microSD instead of SD, I think I like that. Jan 09 05:00:19 yup, although you can easily get by without ever using the µSD at all Jan 09 05:03:30 Thanks, I appreciate the help. Jan 09 05:03:36 no worries Jan 09 05:04:16 Now to think up a project for it. Jan 09 05:05:03 My RasPi is connected to an RTL2832 (SDR), and the arduino's being used as a rotational mount to track satellites. Jan 09 05:05:27 Project: Lego replacement for NXT brain. Jan 09 05:05:33 SOLD! Jan 09 05:06:38 AI6K: are you using a feedback control system to track? Jan 09 05:07:06 Not yet Jan 09 05:07:23 so how? satellite ephemerus data? Jan 09 05:08:14 XBee to send commands manually (I didn't say it was a good system :) Jan 09 05:08:21 i used to work for a little company that did that sort of thing, GTE Government Systems. Jan 09 05:08:29 AI6K: sure. baby steps. Jan 09 05:08:52 Just some simple parallax continuous rotation servos on a camera tripod with an Elk log periodic Jan 09 05:10:03 http://www.elkantennas.com/product/dual-band-2m440l5-log-periodic-antenna/ Jan 09 05:10:32 Bought it a couple years ago at Pacificon, radio is an Icom IC-91AD Jan 09 05:10:34 AI6K: long time no see Jan 09 05:10:47 ¿¿¿ Jan 09 05:10:56 I don't recall ever being on this channel :) Jan 09 05:11:09 i'm kidding, I just saw you in #rasberrypi Jan 09 05:11:14 AI6K: how do you control polarization? Jan 09 05:11:49 I don't Jan 09 05:12:09 I walk to the patio and rotate the arms? Jan 09 05:12:45 lol! Jan 09 05:13:36 we used to run dual-channel monopulse tracking systems at GTE, with selectable V, H, LHC and RHC polarizations. Jan 09 05:14:19 Costing thousands of ???? Jan 09 05:14:28 millions Jan 09 05:14:40 about 40M at the time (early 80s) Jan 09 05:14:42 I don't make quite that much yet. Jan 09 05:14:49 want a loan? Jan 09 05:15:13 we had a feed that provide sum and difference channels, and they were phase and gain matched all the way through to the autotrack unit. Jan 09 05:15:14 I need to build up collateral first. Jan 09 05:15:29 it was pretty cool. Jan 09 05:15:36 Admit it, you were working for SETI :) Jan 09 05:15:48 We phoned home for ET... lol Jan 09 05:16:47 AI6K: have you ever heard of a Watkins Johnson 8618 receiver? Jan 09 05:17:06 we have about 16 of them, $30k each... Jan 09 05:17:08 had Jan 09 05:18:09 http://watkins-johnson.terryo.org/photos/equipment/CEI/WJ-8617-8618/WJ-8617B-26.jpg Jan 09 05:19:08 "Gee. No, GTE" ... remember that? Jan 09 05:19:14 Oh yea Jan 09 05:19:37 anyway, ancient history Jan 09 05:19:55 I always got GE & GTE mixed up. Jan 09 05:20:21 I did contract work for GE, inspecting nuke plants in Pennsylvania (Beaver Valley) Jan 09 05:20:29 GTE Government Systems is now General Dynamics. Jan 09 05:20:39 that sounds cool. are you still glowing? Jan 09 05:24:20 Glowing? It wasn't the Nuke plants that did that, it was the Boomer submarine I served on, sleeping in Missile Compartment. Jan 09 05:24:55 at least you were warm at night.. Jan 09 05:27:20 my dad was USAF for 21 years. Jan 09 05:27:30 thank you for your service. Jan 09 05:30:28 You're welcome, I was glad to do it. Jan 09 05:30:44 (And glad to get out after 6yrs :) Jan 09 05:31:11 ha. Jan 09 05:31:26 i'm the good-looking kid on the left: http://www.digitalsignallabs.com/family.jpg Jan 09 05:33:06 ai6k.com, I'm the one not in the picture Jan 09 05:34:10 That picture cracks me up, you and your brother damn near military post. Jan 09 05:34:21 posture Jan 09 05:34:25 ha. yeah, dad was pretty strict Jan 09 05:34:38 you're in San Ramon? Jan 09 05:34:49 i lived in Silicon Valley for 14 years. Jan 09 05:35:11 mainly san joser. Jan 09 05:35:32 GTE was in Mountain View (still is). Jan 09 06:04:39 Yes, still here in San Ramon, I work in Pleasanton. Worked down in San Jose many times in the past. Jan 09 06:19:55 so no Verizon Gov't Systems? Jan 09 11:11:38 Hi guys Jan 09 11:11:53 I am running a Ubuntu 14.04 on a BeagleBone Black Jan 09 11:12:04 fine Jan 09 11:12:07 I got the image from here: http://elinux.org/BeagleBoardUbuntu Jan 09 11:12:27 Now I have a camera cape attached to the board Jan 09 11:12:28 yes Jan 09 11:12:48 But I am not sure how to load the kernel driver that will mount the cape as a V4L device Jan 09 11:13:02 ON Angstrom I see a /dev/video0 Jan 09 11:13:14 which does not exist on Ubuntu Jan 09 11:13:55 yes Jan 09 11:13:59 diffrent kernels Jan 09 11:14:26 Do I have to compile my own kernel to get access to the camera cape on Ubuntu? Jan 09 11:15:12 possibly Jan 09 11:16:33 online hai koi bc? Jan 09 11:16:59 bc reply karo bsdi walo! Jan 09 11:17:25 hello... is there anybody in there?

Jan 09 11:19:24 eric cartman says hello! Jan 09 11:19:36 mkay? mm? Jan 09 12:50:24 hey Jan 09 12:51:17 can anyone help me with BBB issue? reflashed mmc with debian, as this was it's original OS. However, Cloud9 ide does not work Jan 09 12:51:39 define doesn't work Jan 09 12:52:03 systemctl status cloud9.service tells me that the VFS socket does exist Jan 09 12:52:14 also which image did you use? exact name Jan 09 12:52:59 latest image from beaglebone site Jan 09 12:53:00 Debian (BeagleBone, BeagleBone Black - 2GB SD) 2014-05-14 - Jan 09 12:53:45 root@beaglebone:/var/lib/cloud9/.c9/metadata# systemctl status cloud9.service cloud9.service - Cloud9 IDE Loaded: loaded (/lib/systemd/system/cloud9.service; static) Active: active (running) since Thu, 15 May 2014 02:48:43 +0000; 13min ago Main PID: 1123 (node) CGroup: name=systemd:/system/cloud9.service ├ 1123 /usr/bin/node server.js --packed -w /var/lib/cloud9 ├ 1172 /usr/bin/tmux new -s devel.142 ; set-option -g Jan 09 12:53:58 May 15 02:49:26 beaglebone cloud9ide[1123]: VFS socket disconnect: false 6U0cOaxpX14ETMK0 hwqz1d8r7acnoz May 15 02:51:29 beaglebone cloud9ide[1123]: VFS socket disconnect: false 6U0cOaxpX14ETMK0 hw4z62bs1jbu49k May 15 02:51:29 beaglebone cloud9ide[1123]: VFS connection does not exist Jan 09 12:54:33 cloud9 never accually worked on my end. it always got stuck at startup Jan 09 12:56:21 what's the upside of using cloud9? not questioning your choice here, just curious Jan 09 12:56:33 not sure, just wanted to try it Jan 09 12:58:12 only got the BBB a few weeks ago, so am still trying to figure out the how and what. Had to reflash mmc cos tried reinstalling cloud9 from scratch. which didn't work either Jan 09 13:04:27 you do need cloud9 Jan 09 13:04:31 +not Jan 09 13:05:49 i know that :-) Jan 09 13:06:11 the old fashio way is still the best way Jan 09 13:06:20 *fashion Jan 09 13:06:32 texteditor and command line Jan 09 13:06:37 but still, wanted to try it Jan 09 13:12:53 so? No one? Jan 09 13:13:38 cloud9? no idea Jan 09 13:14:00 damn Jan 09 13:14:03 ok thanks Jan 09 13:45:04 Hi all, I'm a bit confused regarding the SPI-interface towards the expansion header on BBB. It is also connected to the HDMI-driver. How to use it without talking to that cirucit as well? Jan 09 13:45:40 use another SPI? :) Jan 09 13:47:23 there is only one SPI in the expansion header?! Jan 09 13:47:59 nope, 2 Jan 09 13:48:32 I only found SPI1 on pins 29,31,28 and 30 Jan 09 13:48:38 spi1 shares pins with hdmi but spi0 does not Jan 09 13:49:10 17,18,21,22 Jan 09 13:49:17 on P9 Jan 09 13:49:55 yes, but it would like to use I2C1 as well... Jan 09 13:50:16 you can always disable HDMI Jan 09 13:52:28 yes, but that is not a option since I need to use HDMI... Jan 09 13:52:30 and you can move i2c1 to other pins Jan 09 13:53:11 but that will kill access to some MMC, don't remember if it's the eMMC or SD card Jan 09 13:53:30 I was going to fix a dead link on http://elinux.org/Beagleboard:BeagleBone_Black_FAQ but it seems my new wiki account doesn't have the right to make edits Jan 09 13:53:39 anyone know how I go about getting edit rights? Jan 09 13:53:44 pins 24 & 26 Jan 09 13:55:02 hmm actually no.. P9 pins 24 & 26 are not used by eMMC Jan 09 13:55:10 so you could move I2C1 to those pins Jan 09 13:55:37 it's mode 3 on them Jan 09 13:56:20 http://elinux.org/Beagleboard:Cape_Expansion_Headers Jan 09 13:56:28 seems like some nice pinout examples there Jan 09 14:04:03 Great Vaizki! Thanks a lot, that should work =) Jan 09 15:14:19 join OpCharlieHebdo Jan 09 15:14:43 almost. Jan 09 15:27:07 I now want to add more info on supported HDMI cables and screens to the wiki Jan 09 15:27:17 so still interested in how to get edit privs Jan 09 15:31:24 jwatt: Register for an account and wait for moderation? Jan 09 15:31:46 agmlego: I have created an account Jan 09 15:32:07 but I didn't get any notification that a moderator would later enable editing Jan 09 15:32:26 jwatt: Be patient then? Jan 09 15:32:32 and the edit link doesn't appear, so I can't make my changes and await for them to be approved Jan 09 15:32:43 Or, contact one of the people who runs the wiki directly and ask. Jan 09 15:32:46 agmlego: I've no problem waiting Jan 09 15:33:05 I'm just saying I'm left in the dark as to what the process is Jan 09 15:33:18 if that's the process, I'm happy to wait Jan 09 15:33:19 thanks Jan 09 15:33:39 As are we, mostly because none of us are that affiliated with the eLinux wiki. Jan 09 15:33:49 THis is not really the right channel for the query. Jan 09 15:33:55 ah, ok Jan 09 18:30:23 still hoping someone has insight on why a previous release (7.6) works but bone-debian-7.7-console-armhf-2014-10-29-2gb.img does not (on my bbb). Jan 09 18:32:31 is there a know problem with that specific release? Jan 09 18:32:33 known Jan 09 18:38:05 ddrown: i ordered that cable but it probably won't get here til Monday. Jan 09 18:38:48 yates: ah cool. The Fry's store near me had a thing that worked if you have a nearby store with wierd electronics pieces Jan 09 18:39:05 just the Shack Jan 09 18:39:21 I wouldn't think they would have it this decade :) Jan 09 18:39:46 yeah, they're not the DIY store they used to be Jan 09 18:40:00 wish we had a Fry's in this area Jan 09 19:13:31 so i came across this a while back and have been dying to find out more. does anyone know anything about this? I am unable to find it on oshpark. http://uploads.oshpark.com/uploads/project/bottom_image/iLFjrsxJ/i.png Jan 09 19:22:59 mistawright: Looks like the Gaming Cape by Alex Aungurencei, (C)2014. Jan 09 19:24:34 mistawright: And that project (iLFjrsxJ) does not appear to be shared; maybe try contacting the guy directly? Jan 09 20:44:03 hello Jan 09 20:44:22 i would like to install android on my beaglebone Jan 09 20:44:32 but i dont know how Jan 09 20:44:41 could you help me plear Jan 09 20:46:47 Which version? KitKat? Jan 09 20:48:00 any Jan 09 20:48:23 i'm tryin to use the .img andrew henderson Jan 09 20:48:27 but no boot Jan 09 20:48:57 I'm sure you've probably seen this already... Jan 09 20:48:58 http://2net.co.uk/tutorial/android-4.4-beaglebone Jan 09 20:49:45 yes i seen this but i need a manual to dummies Jan 09 20:50:27 Hehehe, ok Jan 09 20:50:47 I'm of no use, I don't own a BBB yet, still researching uses. Jan 09 20:50:59 But I'm leaning towards a NXT replacement. Jan 09 20:51:58 what means NXT Jan 09 20:53:48 maybe lego nxt? Jan 09 21:00:10 does anyone keep up on the RS485 serial driver? I had it working with kernel 3.2 and it broke for me in 3.12. Jan 09 21:03:09 Yes, Lego NXT Jan 09 21:03:21 There's a Kickstarter for a cape for it. Jan 09 21:39:41 Hello, may I ask a question about an issue I'm facing with Yocto build a BeagleBoard image? Jan 09 21:46:48 xultz: shoot Jan 09 22:00:24 Thank you FileNotFound. I followed a tutorial to generate an image (using QT5 and stuff), but when I boot the board, it claims it cannot find the kernel uImage. By looking into the rootfs partition, inside /boot, there's only a zImage kernel. What should I do? Jan 09 22:59:09 rcn-ee: hi I booted your 3.19-rc3 , please tell me how to load a device tree to pull up gpio48 Jan 09 23:00:29 add a node in the dts to do it.. Jan 09 23:01:21 thanks , I found this page to learn how to do it: http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/gpio/gpio.txt Jan 09 23:01:29 any better advice? Jan 09 23:01:45 where to send you fixes to your scripts? Jan 10 01:26:24 anyone know how to get lxc working on th BBB? **** ENDING LOGGING AT Sat Jan 10 02:59:59 2015
