**** BEGIN LOGGING AT Sun Sep 14 02:59:59 2014 Sep 14 03:15:36 hello I have found an old beaglebone white laying around. It has a flash card but i am sure it has been fdisked. Is there a way to pxeboot install headless this white board with a version of linux or openbsd? Sep 14 03:16:11 you should be able to get uboot up on a network and tftp Sep 14 03:16:31 i do not have a microsd card adapter so I cannot dd an image Sep 14 03:16:36 uboot... ok Sep 14 03:16:46 would be a first step Sep 14 03:17:00 yeah i have a network and tftp i just reinstalled the soekris last night Sep 14 03:17:03 ok Sep 14 03:17:11 thanks for push in right direction Sep 14 03:17:20 embedded essentials - uSD/SD usb adapter/ usb->3v3 debug cable :D Sep 14 03:17:51 hopefully you can tftp a kernel image .. and then perhaps nfs a rootfs? Sep 14 03:18:14 you could tftp a rootfs if its squashfs or somethign maybe Sep 14 03:18:31 there's a few optoins :) Sep 14 03:19:40 or i could just goto bed and get an microsd card adapter tomorrow... Sep 14 03:19:43 =] Sep 14 03:19:51 ok i will check it out thanks Sep 14 03:20:08 lol indeed Sep 14 03:29:39 hello? Sep 14 03:38:49 Hello guys Sep 14 03:39:11 I tried using the vncserver on my BBB to run opencv Sep 14 03:39:42 when I try to display an image I get - GTK Warning cannot display Sep 14 03:39:58 What could be the solution for this !? Sep 14 04:56:04 Can i practice device driver development with beagleboard black or other boards ? Sep 14 04:56:38 I'm seeking a device for linux device driver development Sep 14 08:07:19 Hello ! I used my BBB over vncserver on my laptop and tried displaying an image using OpenCV Sep 14 08:07:36 I get a GTK Warning cannot display Sep 14 08:07:51 What could be a possible solution ? Sep 14 08:08:31 I'm a newbie to linux so i was not able to understand lot of answers in other websites Sep 14 08:14:37 an important thing to understand is that you are experiencing a problem that is solely software related and not connected to hardware Sep 14 08:15:19 nevertheless, please provide more information on what exactly you are doing Sep 14 08:44:00 hello, my bbb doesnt show serial debug and when i run setserial on ttyO1 i get /dev/ttyO0, UART: undefined, Port: 0x0000, IRQ: 88 how can i fix it? Sep 14 08:45:11 why do you get an error message for ttyO0 if you run it on O1? Sep 14 08:55:30 sorry i mistyped 0 -> 1, btw i get this error for all ttyO* tbr i tested all terminals minicom ,screen but no lock communicating with serial port Sep 14 08:56:09 only ttyO0 is muxed by default Sep 14 08:56:23 have you enabled any of the other serial ports? Sep 14 08:56:44 no i didn'r change anything. Sep 14 08:57:03 also ttyO0 has this problem Sep 14 08:57:12 then look into muxing, DT overlays Sep 14 08:57:39 where are they? Sep 14 08:59:18 enabling serial ports on the BBB is a well covered topic. Sep 14 08:59:21 Have you tried perusing the internet search engine of your least distrust, yet? Sep 14 09:00:50 I'm trying to use my BBB over vnc and run opencv programs Sep 14 09:01:16 yes but by default the serial debug should work but for me, ! Sep 14 09:01:26 I get GTK warning cannot display when I try to display an image Sep 14 09:01:59 raj_: as I told you before: Sep 14 09:02:00 08:14:37< tbr> an important thing to understand is that you are experiencing a problem that is solely software related and not connected to hardware Sep 14 09:02:03 08:15:19< tbr> nevertheless, please provide more information on what exactly you are doing Sep 14 09:02:41 I'm using opencv appliction for image processing Sep 14 09:02:44 milad: yes, the debug port should be enabled if you are using the standard debian image Sep 14 09:03:02 raj_: you said that already. what exactly are you doing? Sep 14 09:03:24 I want to display image and video Sep 14 09:03:48 I dont have a HDMI screen so using my laptop Sep 14 09:04:31 raj_: how are you running that software of yours? Sep 14 11:02:36 so, who is in ELCE now? Sep 14 11:30:03 hey, anyone here who used the PRU on the BB Black? Sep 14 12:17:35 hi! Sep 14 12:17:59 is there an image for a BBB with g++ 4.8? Sep 14 12:19:36 debian doesn't have 4.8. Stable has 4.6, testing 4.9 Sep 14 12:20:23 Humpelst1lzchen: thanks... maybe i'll try testing... Sep 14 12:20:52 * tbr was about to suggest the same, try a jessie image, if you can find that. RCN might have it Sep 14 12:23:30 well, maybe g++-4.7 is enough... Sep 14 12:23:50 just wanted to play around with some c++11 features Sep 14 12:30:28 yay, seems to compile and even work.... no new image needed (for now) :) Sep 14 14:42:27 hi guys I have built a realtime kernel on my desktop for my beaglebone black and I have done this by following the ardupilot instructions. I am using ubuntu on on my beaglebone black and doesnt appear that the instructions for copying the kernel to the boot partition is right for my situition Sep 14 14:42:40 i don not have a zImage file in my boot partition Sep 14 14:43:15 what did it create? Sep 14 14:46:22 thurgood: http://dev.ardupilot.com/wiki/building-for-beaglebone-black-on-linux/ in this article it creates a zImage file Sep 14 14:47:12 i do not see one in my current boot partition nor do is a uInitrd that is referenced as well Sep 14 14:50:33 yeah I think you should have the uInitrd for debian :/ Sep 14 14:53:46 these are the files and folders in my boot directory: http://pastebin.com/bWvi93EB Sep 14 14:55:24 what's in your /boot/uboot folder? Sep 14 14:55:38 nothing Sep 14 14:56:38 hmm, I thought that's where the kernel is supposed to go now Sep 14 14:57:05 as well as everything uboot needs Sep 14 14:57:39 you're sure it's empty? Sep 14 14:57:49 mistagood, you need to mount your SD card on your pc and then run the commands Sep 14 14:58:30 let me know where you are stuck, are you using these instructions: https://github.com/erlerobot/wiki/wiki/Installing-ArduPilot Sep 14 14:59:18 or similar ones Sep 14 14:59:31 sounds like your uboot partition is not being mounted to /boot/uboot/ Sep 14 20:23:16 hi. which kernel is recommended for playing with the PRUs? i tried 3.8.13-bone47 (original) and 3.8.13-bone64 but both seem to give empty /sys/class/uio after modprobe uio_pruss Sep 14 20:23:50 this is a bbb from digikey, 2 months ago, running debian Sep 14 20:32:48 Question... how difficult would it be to set up a PSP screen for the beaglebone black? Sep 14 20:33:47 doelie what do you want to do with /sys/class/uio? Sep 14 20:35:44 LuaStoned: access the PRUs using libprussdrv.so -- is there another way? Sep 14 20:37:25 well, I just started reading about the PRU two days ago.. this getting started guide helped me quite a bit: http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/05/22/bbb--working-with-the-pru-icssprussv2 Sep 14 20:42:58 thanks i'll have a look at the device tree stuff. Sep 14 20:43:22 what i read though is that kernel 3.8 has problems with the driver: Sep 14 20:43:35 https://groups.google.com/forum/?fromgroups=#!topic/beagleboard/gqCjxh4uZi0 Sep 14 20:44:00 ppl mention using 3.2 Sep 14 20:44:10 i wonder if a more recent one is better? Sep 14 20:44:12 I tested various example programs and they seem to run fine? Sep 14 20:44:26 what kernel are you running? Sep 14 20:44:36 btw I'm on 3.8.13-xenomai bone53 Sep 14 20:44:49 did you compile from source? Sep 14 20:44:53 Yeah Sep 14 20:45:21 ok i should probably try that.. where did you get the xenomai tree? Sep 14 20:45:47 https://github.com/cdsteinkuehler/linux-dev Sep 14 20:46:29 I'm pretty sure the default / most recent kernel works just fine if you follow the steps mentioned Sep 14 20:47:53 ok. thanks! Sep 14 20:50:00 doelie im sorta curious, what do you want to use the PRU for? Sep 14 20:55:14 LuaStoned: interest peaked by logic analyzer mentioned on hackaday - some links gathered here http://zwizwa.be/-/electronics/20140724-000847 Sep 14 20:57:15 LuaStoned: in general i like the combo of general purpose linux box + small microcontroller. used xenomai before but still nothing beats a high MHz cycle-accurate core. Sep 14 20:59:09 LuaStoned: the BeagleLogic http://www.theembeddedkitchen.net/tag/logic-analyzer/ Sep 14 21:19:03 doelie looks like a cool project, will give it a read Sep 14 22:09:49 good morning all, i have a BBB i bought early last year. i suspect it's quite outdated now and i'd like to update it completely before playing with it again. i suspect i just download the latest image and follow the instructions? is there something else i'm missing? also, i notice there is both a debian and angstrom distribution, any reason for choosing one over the other other than "I'm more used to this distro"? Sep 14 22:16:54 my beaglebone black root usb is connected to a hub on this hub my mouse and keyboard work yet when i open a terminal and type sudo fdisk -l i do not see my usb flash drive why? Sep 14 22:25:43 Moult .. personal preference .. latest images should be on the beagleboard main site. Sep 14 22:26:06 is python or java better for robotics? Sep 14 22:26:12 or does it not matter? Sep 14 22:28:28 c :P Sep 14 22:28:36 not a whole lot in it I'd say Sep 14 22:32:47 veremit: cheers :) Sep 14 22:34:06 np **** ENDING LOGGING AT Mon Sep 15 02:59:59 2014
