**** BEGIN LOGGING AT Sun Mar 22 02:59:58 2015 Mar 22 03:29:00 in theory you should have access to full gpio on all pins except the (dedicated) voltage/ground/analog-in pins Mar 22 03:29:43 some gpios will default to serial, i2c, spi, pwm Mar 22 03:30:44 this one is really basic => http://graycat.io/beaglebone/beaglebone-pinout/ Mar 22 03:35:29 depending on kernel/device tree support it can be different, so that makes it extra fun... Mar 22 04:02:43 Hi, i upgraded the linux kernel to 3.19 on BB-xM Rev C. And on boot up I get mmc0: error -110 whilst initialising SD card Mar 22 04:02:57 Can someone please help? Mar 22 04:06:25 Nash_: do you ahve any support credits. Mar 22 04:10:15 no Mar 22 04:13:19 no soup Mar 22 04:15:04 where'd you get the 3.19 kernel? Mar 22 04:16:21 maybe wiki page is slightly behind, but i only see 3.18 rcn kernel as latest for beaglebaord Mar 22 04:16:36 i ran the update_kernel.sh in opt/scripts/tools Mar 22 04:17:22 in the armv7multi one? Mar 22 04:17:27 ya Mar 22 04:18:14 * nerdboy doesn't have beagleboard to test, so you'll have to ask robert Mar 22 04:19:07 you could bisect, or at least check the config to see if somethign got dropped Mar 22 04:20:59 does it have anything to do with omap2_set_init_voltage: unable to find boot up OPP for vdd_mpu_iv? Mar 22 04:25:24 And should we choose armv7 or armv7-lpae for conf_kernel for BBxM? Mar 22 04:35:00 don't use lpae unless that shows up in your cpu flags Mar 22 04:38:16 ok Mar 22 08:19:25 got new beagle board black C, can any one suggest android port with source code Mar 22 08:19:27 for same Mar 22 08:21:17 not many people around here bother with android on the BBB Mar 22 08:22:04 tbr, any other Linux port ok to start with . Mar 22 08:22:33 there are official debian images linked from beagleboard.org Mar 22 08:22:49 and in depth explanations on RCN-ee's website/wiki Mar 22 08:22:55 and the elinux wiki Mar 22 08:25:44 tbr, thank you Mar 22 09:55:20 my bbb usb is not working but it can power bbb Mar 22 09:55:44 chandy: did it work before? Mar 22 09:56:20 yes Mar 22 09:56:59 tbr:yes Mar 22 09:57:14 chandy: so, what did you change? Mar 22 09:58:34 tbr:i tried ubuntu 14.04 image then i have to experiment sone bonescript ,so i changed to amstrong Mar 22 09:59:29 it might be that the angst-rom image simply doesn't have the USB functionality enabled Mar 22 09:59:40 ok Mar 22 09:59:58 so what should do ? Mar 22 10:00:24 that depends Mar 22 10:00:39 is there a specific reason why you want to use angstrom? Mar 22 10:01:08 i want to work on bonescript Mar 22 10:01:22 <_av500_> is that not in the current debian? Mar 22 10:01:27 didn't the debian image also support that? Mar 22 10:02:14 tbr:i tried debian also Mar 22 10:02:19 same problem Mar 22 10:02:32 and flashed the emmc Mar 22 10:02:43 so, let's make sure you get this right Mar 22 10:02:57 take the flasher image, prepare a sdcard with it Mar 22 10:03:00 tbr:sure Mar 22 10:03:22 insert card, hold down the boot button, connect power. Mar 22 10:03:47 wait till it finnishes flashing. Mar 22 10:03:54 wait some minute more Mar 22 10:04:15 tbr:yes i have done that but no improvement Mar 22 10:04:18 remove card, reboot board, let it sit for 20min, check if USB works Mar 22 10:04:30 which revision is your BB? Mar 22 10:06:13 tbr:REV C Mar 22 10:06:39 what's the size of your SD-card? Mar 22 10:07:00 32gb Mar 22 10:07:29 tbr:but i created image using win32diskimager Mar 22 10:07:29 do you have a so called "FTDI cable" to attach to the debug UART? Mar 22 10:08:23 no Mar 22 10:09:36 hey.. new to beaglebone and to IRC as well.. was wondering if anyone could help me out with setting up the blacklib library. Mar 22 10:09:38 did you uncompress the image before feeding it to the imager? Mar 22 10:09:54 tbr:yes Mar 22 10:11:39 chandy: then it should work. just reflash the board again. this time give it ample time to flash AND for first boot wait 20min. If you then don't see it over USB, reboot the board once. Mar 22 10:11:56 also you could check if attaching ethernet to a LAN wouldn't work for you Mar 22 10:12:52 tbr:attaching ethernet to my PC directly not working Mar 22 10:13:27 tbr:but using router and then ssh is working fine Mar 22 10:13:38 chandy: you'd need to have a DHCP server and other things running for that to work. that's out of scope. If you want to go for a direct ethernet connection, learn about "Internet Connection Sharing" Mar 22 10:15:04 tbr:Internet Connection Sharing by direct connection? Mar 22 10:15:34 chandy: if LAN works for you, why do you need USB? Mar 22 10:16:32 can i use lan and router to run bonescript Mar 22 10:16:59 tbr:direct connection is not working in lan Mar 22 10:17:02 yes, if it's in the image, then it's irrelevant if you access it over USB or over LAN network Mar 22 10:17:54 ok Mar 22 10:19:08 tbr:so i can run bonescript using ssh via router ? Mar 22 10:19:42 why ssh? Mar 22 10:19:51 just access it directly Mar 22 10:20:03 how: Mar 22 10:20:11 how? Mar 22 10:20:20 just as you would over usb networking? Mar 22 10:21:02 tbr:excuseme i couldn't get it Mar 22 11:43:23 Hi i tried installing Trusty 14.04 on BBxM using the netinstall method. And after installation it says kernel panic - not syncing: Attempted to kill init! Mar 22 11:43:39 Any help is greatly appreciated Mar 22 11:44:07 * _av500_ wonders what a tursty is Mar 22 11:46:14 Ubuntu Trusty 14.04 Mar 22 12:52:10 ddrown: i just had a look at http://blog.dan.drown.org/tcxo-beaglebone-black/ and http://blog.dan.drown.org/tcxo-beaglebone-black-part-2/ Mar 22 12:53:08 ddrown: firt thing that strikes me: measuring the temp dependence of the BBB oscillator relative to an TCXO of unknown quality will not give you any good results. You should get one of the Rb normals from ebay instead Mar 22 12:54:18 ddrown: search on ebay for "FEI 5680" Mar 22 12:55:00 ddrown: as for the offset of the 24MHz TCXO, that's normal. the 2.5ppm are the variation over temperature, they do not include the offset of the nominal frequency Mar 22 12:55:30 ddrown: also, aging of 200ppb/day for a new, low quality crystal is pretty normal Mar 22 12:55:46 ddrown: probably dominated by the power cycle retrace Mar 22 13:03:41 ddrown: pinout for the FEI5680 can be found here: http://www.ko4bb.com/dokuwiki/doku.php?id=precision_timing:fe5680a_pin-out Mar 22 13:04:20 ddrown: please note that the FEI5680B and FEI5680A have different pin-outs, the first one (written by bob camp) is the one for the currently sold units Mar 22 16:55:42 KotH: I was measuring the TCXO's temp dependence against the GPS's PPS, but I agree with the rest of what you said. a Rb frequency source would be better Mar 22 16:56:50 I was expecting the TCXO's temp dependence to be better than it was, but I see now that I was expecting too much Mar 22 16:57:17 can the bbb run unvanquished(game) Mar 22 17:06:00 RicoSuave: does that game a) run on linux or android and b) have source you can compile or prebuilt binaries for arm? Mar 22 17:06:16 RicoSuave: if yes and yes, then yes. Mar 22 17:07:34 https://en.wikipedia.org/wiki/Unvanquished_%28game%29 Mar 22 17:07:49 https://github.com/Unvanquished/Unvanquished Mar 22 17:16:42 hello I want some technical help regarding driver development in BBB for posix system Mar 22 17:17:33 that system ported successfully on BBB and I can run helloworld sample example Mar 22 17:18:56 it would be great if some one can help Mar 22 17:22:53 ? Mar 22 17:24:47 namaste: nobody can help you unless you say what your problem is Mar 22 17:25:08 ddrown: oh.. then i misread your blog post Mar 22 17:25:51 ddrown: yes, manufacturers tend to cheap in all kinds of ways in datasheets. especially when it comes to noise performance, accuracy or stability Mar 22 17:26:24 KotH : I want develop driver for rtems on BBB. So basically I need to write gpio.h file Mar 22 17:26:24 ddrown: often i even have the impression, that the manufacturer does not know what these terms mean or how they are measured :) Mar 22 17:26:43 so want to ask that how can I proceed? Mar 22 17:27:49 namaste: i would read the available documentation, then the available source Mar 22 17:28:06 https://docs.rtems.org/doc-current/share/rtems/pdf/bsp_howto.pdf Mar 22 17:28:11 documentation Mar 22 17:28:19 namaste: ie, do what you would do when you would need to learn some random system Mar 22 17:29:54 KotH: developed for raspberry pi. https://github.com/asuol/RTEMS_rpi_testing/blob/master/GPIO/LIBGPIO_TEST/init.c Mar 22 17:54:13 KotH: am I not clear? Mar 22 17:56:38 namaste: well, you seem to expect that i read that documentation and tell you what to do Mar 22 17:56:46 namaste: i will not do that Mar 22 17:57:03 I doesn't actually . Mar 22 17:57:29 then i dont understand what you are asking Mar 22 17:57:54 I wish you to tell me how to proceed for the driver development any posix system Mar 22 17:58:13 like I want to develop for gpio Mar 22 17:58:28 what kind of things should be there Mar 22 17:58:39 18:27 < KotH> namaste: i would read the available documentation, then the available source Mar 22 17:59:44 any documentation available from BBB Mar 22 17:59:51 for drivers Mar 22 18:00:04 depends on what you are asking Mar 22 18:00:13 the processor is documented in the TRM Mar 22 18:00:29 writing drivers is documented in the kernel sources Mar 22 18:00:39 er.. wait, it's not linux you are asking for Mar 22 18:00:45 can I have link pls ? Mar 22 18:00:48 i dont know where rtems documents its drivers Mar 22 18:01:02 yep thats what I am asking Mar 22 18:01:26 ok but like i need to have i2c interface from arm to gpio chipset Mar 22 18:01:47 i dont know rtems Mar 22 18:01:49 never used it Mar 22 18:01:55 ya i knw Mar 22 18:02:00 lets take linux Mar 22 18:02:23 I will do other stuff like switching linux to rtems Mar 22 18:02:33 but in linux how does it happen? Mar 22 18:02:41 http://bit.ly/1C2Hiuf Mar 22 18:03:28 ok... :) Mar 22 18:03:30 thanks Mar 22 18:03:39 KotH: nice time with you Mar 22 18:05:42 hello i've got a question.. how to I get kernel headers into the beaglebone default OS Mar 22 18:06:08 i'm trying to compile v4l device firmwares Mar 22 18:06:19 so i can use a capture card with zoneminder Mar 22 18:09:03 apt-get install linux-header or something like that Mar 22 18:09:16 dont remember what debian used as package name for that Mar 22 18:10:16 aptitude search linux|grep header should give you what you are loking for Mar 22 18:13:39 "E: Unable to locate package linux-header" Mar 22 18:14:01 oh sorry didn't see last part Mar 22 18:14:07 excuse i'm a bit stupid Mar 22 18:17:38 sadly i unstalled a fuckload off pointless shit trying to figure this out Mar 22 18:17:40 so i'm diskfull Mar 22 18:17:53 will have to return everything to a pristine state Mar 22 18:19:04 what would be the smartest image to use for a fresh install Mar 22 18:19:20 given that i'll be doing zoneminder+v4l Mar 22 18:22:16 i have no idea Mar 22 18:22:31 * KotH doesnt use desktop distros on embedded devices Mar 22 19:56:16 KotH: heh yeah, I wouldn't be surprised to find TCXO manufacturers that just copied someone else's datasheet and said "good enough!" Mar 22 19:58:22 hello can I have file that have mapped all the registers of ARM beagleboard . can be known as beagleBoard.h Mar 22 19:58:51 I would like to have a copy, too.

Mar 22 20:14:39 ddrown: http://www.satsignal.eu/ntp/BBB-vs-RPi.html Mar 22 20:15:07 columns are: stratum(1), poll interval in 2^x (10), reachability bitfield, time since rx, offset[cooked offset] +/- stddev Mar 22 20:16:05 "To get the BBB working it was necessary to add a separate magnetic mount GPS antenna, as the board itself seems to produce enough interference to block nearby GPS reception" Mar 22 20:16:12 heh, I experienced that too Mar 22 20:16:14 ah.. ntpq -p output Mar 22 20:16:38 yes, the BBB is known to be an EMI nightmare Mar 22 20:16:47 "The first thing I note is that there is a lot more background CPU activity on the BBB" - well, there's your problem right there Mar 22 20:16:58 BBB should not be at 75% cpu serving NTP Mar 22 20:17:27 CPU heat will drive the oscillator to swing pretty wildly Mar 22 20:17:42 because it's not constant CPU usage Mar 22 20:22:04 does the default debian image of the bbb run systemd or sysV init?

Kindly help me Mar 22 20:36:17 .o0(and i am new to space travel. kindly help me) Mar 22 20:47:23 hello, I have mainline kernel 3.19 and I wonder how can I load a device tree overlay with this kernel Mar 22 20:47:54 it seems that device tree overlays were reintroduced with this kernel but I can't find any documentation how to use them Mar 22 20:55:48 hi all - is this the channel to ask questions about the beagle bone black rev.c board? new user here. Mar 22 20:58:52 am i in the right channel? Mar 22 21:05:01 yes it is Mar 22 21:10:45 ok, here's my question — i have the new Beaglebone Black Rev. C board with Debian 7.4 on it & linux kernel 3.8.13-bone47 Mar 22 21:13:21 i am connecting to it from a dev Chromebook, an Acer C720P, and i have the BBB connected via USB to that. my problem is: i cannot get the BBB to bridge its interenet connection from the Chromebook via the USB. i want to be able to update the node.js on the BBB to node 0.10.36 & update the npm on it and such, but can't do that with npm unless i have an internet connection. any help here? Mar 22 21:19:51 hi , someone have this cape http://openhacks.com/page/productos/id/981/title/BeagleBone-Black-Expansion-%28Capacitive%29-5-inches#.VQ8x8VmYreQ ? Mar 22 21:20:33 back, sorry. lost connection. do i need to re-state my quesition? i didn't see any answers come through. Mar 22 21:21:38 faddah_: why not use ethernet? Mar 22 21:22:26 don't have that where i am, just wifi coming into Acer C720P Chromebook, and usb to Beaglebone Black from there. Mar 22 21:22:57 tbr - shouldn't i be able to bridge the connection to the BBB so it sees the interent? Mar 22 21:23:05 internet, pardon. Mar 22 21:23:46 faddah_: that's mostly a chromebook question Mar 22 21:23:56 and I have zero clue about those Mar 22 21:24:43 ok, so anybody else ever bridge their ethernet from a Chromebook to a Beaglebone, black or otherwise, or from a vanilla Linux box? because under the hood, ChromeOS is just linux. Mar 22 21:31:36 back - irc server keeps restarting on me. grumble mumble mumble... Mar 22 21:32:21 so has anyone else successfull bridged internet connection from their Chromebook or Linux laptop to a Beaglebone Black Rev. C? that is what i need help with here. Mar 22 21:40:17 i'm also posting something on Beaglebone.org community forums. Mar 23 00:33:15 Hello. Maybe one of you can help me out here? Trying to install latest version of TOR (https://www.torproject.org/docs/debian.html.en) using a beagleboard C5 running debian from (https://rcn-ee.net/rootfs/2015-02-19/) but cannot seem to compile as no compiler found. I also tried to run Ubuntu to install latest version of TOR but no go. Any help? Would greatly appreciate it :) Mar 23 00:35:21 have you tried installing a compiler? Mar 23 00:36:20 I am fairly new to linux... Not sure how to intall one Mar 23 00:36:25 Tried gcc but no go Mar 23 00:36:58 I get this result "Package gcc is not available, but is referred to by another package.

Mar 23 00:46:42 been at this alll weekend Mar 23 00:46:57 it's build-essential, not base-devel Mar 23 00:47:01 I was wrong at first Mar 23 00:47:28 "Package build-essential is not available, but is referred to by another package.

Mar 23 00:56:03 *cross Mar 23 01:03:14 cross compile means to compile using a computer that isn't the computer you're running it on, especially if it's a different architecture Mar 23 01:03:29 but you need to set up the cross compilation environment to do that and that's a huge pain Mar 23 01:04:51 Well it seems i'm at a dead end trying to use my beagleboard... Mar 23 01:04:55 Might have to look into that option Mar 23 01:12:29 well, I found this http://marcin.juszkiewicz.com.pl/2010/10/19/how-to-cross-compile-arm-kernel-under-ubuntu-10-10/ Mar 23 01:12:39 will look into it tomorrow after work Mar 23 01:12:43 wish me luck! :P Mar 23 01:46:50 i need tslib for work my touchscreen? **** ENDING LOGGING AT Mon Mar 23 02:59:59 2015
