**** BEGIN LOGGING AT Thu Jul 02 02:59:59 2015 Jul 02 08:15:41 Hello. in linux kernel source, what should i modify to change screen resolution? Jul 02 08:15:49 board is BBB Jul 02 10:49:04 hi Jul 02 10:50:09 i am able to run pointgray flycapture camera with its sdk application (created in glade) Jul 02 10:50:29 i have developed my own application in qt. it is not able to start camera previes Jul 02 10:50:45 it is telling that frame is not able to acquire Jul 02 10:50:51 what should i do Jul 02 10:54:15 dthepok does your qt application runs on your linux desktop with this cam? Jul 02 10:54:22 if not Jul 02 10:54:28 you are on the wrong channel Jul 02 10:58:47 Is anybode using here using a touchscreen and can tell me, that with tslib the tool ts_calibrate works well, but the pointer doesn't move in the normal Xserver? Jul 02 10:59:28 Here my X11 Log: http://pastebin.com/Y2WbMFL9 Jul 02 11:00:31 hm you still fighting with it? Jul 02 11:01:50 ^ this what meant for User1234 Jul 02 11:02:03 so tslib driver does not work also Jul 02 11:10:19 yeah. still fighting :-( Jul 02 11:10:54 is really annoying. I know the screen works Jul 02 11:10:59 @woglinde. yes i am able to run that qt application on ubuntu. it is woking fine. but not woking in beaglebone black Jul 02 11:11:43 because I can calibrate.. but why doesn't X11 use. I've never seen such sort of annoying software Jul 02 11:11:58 it's as faw away from "plug & play" as it can be Jul 02 11:12:46 I dont know where to ask. There is no really x11 support Jul 02 11:22:06 So any suggestions? 2 Weeks and no effort :-( Jul 02 11:33:45 hi all, i have developed point gray flycapture camera preview application in qt5. it is working in ubuntu. but it is not working on beaglebone black giving error that grab loop has an error : Isochronous image transfer is not started. since the camera preview application from its sdk is working fine (developed on glade). what should i do? thanks!!

Jul 02 12:21:36 Guest67454 repeating the question from time to time annoys most people here Jul 02 12:21:45 Guest67454 is the cam an usb camera? Jul 02 12:21:55 yes it is usb camera Jul 02 12:22:10 sorry for repeating question Jul 02 12:22:26 did you check with other tools from video 4 linux if the cam is working correctly? Jul 02 12:22:50 yes, i have used its sdk sample application. it is working fine Jul 02 12:22:54 User1234_ sorry you have this much trouble Jul 02 12:23:18 User1234_ and I think you need to look into the source code of tslib or evdev Jul 02 12:23:27 beaglebone is not able to acquire frame by camera Jul 02 12:23:31 giving error Jul 02 12:23:41 error : Isochronous image transfer is not started Jul 02 12:23:45 Guest67454 again the sdk app works on bbb and your qt ab not Jul 02 12:23:52 yes Jul 02 12:24:01 did you google for the error? Jul 02 12:24:15 did you use the same qt version desktop? Jul 02 12:24:20 yes, it tells that it doesnot have suffient power supply Jul 02 12:24:21 maybe qt has some problems Jul 02 12:24:24 yes Jul 02 12:24:31 same qt version i have used Jul 02 12:24:31 which is fixed in some later version Jul 02 12:24:33 okay Jul 02 12:24:42 sorry than I have no idea Jul 02 12:25:10 ok\ Jul 02 12:25:25 do you know anyone who can answer this Jul 02 12:32:19 i have developed point gray flycapture camera preview application in qt5. it is working in ubuntu. but it is not working on beaglebone black giving error that error :- grab loop has an error : Isochronous image transfer is not started. since the camera preview application from its sdk is working fine with beaglebone (developed on glade). i am not able to figure out whats wrong with it. what should i do? Jul 02 12:32:35 Did anyone here buy a BBB lately? how much time until you got it? Jul 02 12:33:05 I want to know if the lead time improve since a year ago Jul 02 12:33:38 around 6 month ago Jul 02 12:34:02 deep: did you order half a year ago? Jul 02 12:34:22 yes Jul 02 12:35:16 wow, can anyone give a shorter lead time? Jul 02 12:36:34 My rule of thumb is - if the price is right on ebay, they are in reasonable stock - I would just go ahead and order something like http://www.ebay.com/itm/Free-shipping-Original-ELEMENT14-beaglebone-black-Rev-C-AM335X-BB-Black-/111706595188?pt=LH_DefaultDomain_0&hash=item1a023b5f74 Jul 02 12:37:58 but, I need to buy from digi key to support rcn-ee - no? Jul 02 12:38:50 Don't know - living in Europe ordering from China tends to be the best option - both with regards to price and leadtime Jul 02 12:40:33 behnchod Jul 02 12:40:43 teri maa ka Jul 02 12:40:52 mai tujhe hath manga tu mujhe lavda de rha hai\ Jul 02 12:40:54 gandu Jul 02 12:51:12 hi, I've successfully built for bbb using latest stable buildroot (2015.05-rc3). created fat32 (bbotable) and ext4 partitions containing the result of the build. can't get the board to boot off microSD Jul 02 12:51:40 whats in the boot partition? Jul 02 12:51:44 no previous experience with bbb so I'm probably doing something wrong I guess Jul 02 12:52:12 zino_: i'd recommend you spend $5 on a cheap usb2serial Jul 02 12:52:24 going blind when doing stuff like that is always a pain Jul 02 12:53:00 av500: already ordered: I was hoping to ssh into the board (I've included dropbear in the build) Jul 02 12:53:05 http://git.buildroot.net/buildroot/tree/board/beaglebone/readme.txt Jul 02 12:53:20 I've followed ^^^, do here you see which files Jul 02 12:53:47 you can ssh once it boots Jul 02 12:53:53 so its no use to debug boot issues :) Jul 02 12:54:21 zino_ why you are using buildroot? Jul 02 12:54:56 woglinde: why are you asking this question? Jul 02 12:55:01 because I've used in the past with rpi and quemu and I'm quite productive with it Jul 02 12:55:10 woglinde: I have used buildroot too with BBB Jul 02 12:55:20 so ask me instead :) Jul 02 12:55:47 zino_: is the FAT partition marked "active" aka bootable? Jul 02 12:55:57 do you hold down the boot button at power on? Jul 02 12:56:16 av500: it' marked bootable and lba (seen with gparted) Jul 02 12:56:52 ok Jul 02 12:56:56 av500: I press S2 and power on the board but at the end I get to the fw in eMMC Jul 02 12:57:06 av500 just to know Jul 02 12:57:06 hmm Jul 02 12:57:17 then it does not see the boot loader on the card Jul 02 12:57:18 av500 maybe he is taking some paing Jul 02 12:57:25 as we see now Jul 02 12:57:47 the pain is the same for all Jul 02 12:57:49 again: no previous experience with bbb and I might be missing something obvious Jul 02 12:57:55 zino_: not really Jul 02 12:58:32 and using debian on both rpi and bbb is productive too these days Jul 02 12:58:38 woglinde: sure Jul 02 12:58:58 and no large cross compile overhead Jul 02 12:59:15 and easier deployment Jul 02 12:59:44 or has build root some package managment now? Jul 02 13:00:16 with debian you don't get a rootfs of 5 Mb Jul 02 13:00:27 I'm a big debian fan though Jul 02 13:00:31 lol Jul 02 13:00:50 you can create one though :=) but that wouldnt really be debian Jul 02 13:01:13 init=/bin/sh ... and only have busybox in your rootfs Jul 02 13:01:18 in my days we were happy to have a 5MB HDD Jul 02 13:01:22 back to my problem: would you suggest anything else? Jul 02 13:01:28 zino_: get a serial Jul 02 13:01:48 I've don it already... will have to wait until it arrives Jul 02 13:01:50 (i think the smalles real debian rootfs you can create is around 80MB) Jul 02 13:01:53 once you have it, you will find something like a tiny typo somewhere :) Jul 02 13:02:08 zino_: you could kill MLO and uboot on the EMMC Jul 02 13:02:26 I tried to kill MLO Jul 02 13:02:26 just to rule out that the buildroot MLO sees the other uboot Jul 02 13:02:32 it refused to die? Jul 02 13:02:58 I guess so. let me try to get rid of uboot too... bbl Jul 02 13:02:59 zino okay if you need 5 mb rootfs Jul 02 13:09:42 so, here's what I've done (and there's certainly something wrong in this): Jul 02 13:10:41 - unpluge/replug BBB Jul 02 13:11:10 on the windows device list I see drive L and delete from it MLO/uboot Jul 02 13:11:35 unplug/replub bbb (without caring about S2 button) Jul 02 13:12:03 zino just wait for the cable Jul 02 13:12:19 all other sutff now is like a functional crystal ball Jul 02 13:12:30 on the monitor (via HDMI) I see again the debian image starting up Jul 02 13:13:21 than you boot from emmc Jul 02 13:13:27 woglinde: if the current stable buildrootis known to work it must just work. if it does not it's me doing something wrong: not time for me to give up yet Jul 02 13:13:32 try to boot first from sd card Jul 02 13:13:44 zino_: then you are not killing MLO/uboot Jul 02 13:13:54 than find a way to copy your rootfs to the board Jul 02 13:14:07 ok, how do I access to emmc content? I guess i deleted from microsd Jul 02 13:14:26 *g* Jul 02 13:14:27 ssh into the board Jul 02 13:14:33 ok Jul 02 13:14:34 see whats mounted Jul 02 13:14:40 remove the card Jul 02 13:14:52 then you are sure you dont delete it from the card :) Jul 02 13:14:58 I would remove the card before booting Jul 02 13:16:16 I've done mount and see the list of partition. then I remove the microsd and run mount again Jul 02 13:16:27 /bin/mount no such command Jul 02 13:16:38 * zino_ confused Jul 02 13:17:11 so it's running off the microsd? Jul 02 13:17:33 which is not possible because I see debian graphical interface on the screen Jul 02 13:24:50 zino_: boot without the sd Jul 02 13:27:07 av500: without the microSD inserted, I get to a "eMMC flasher" screen with an error at the end Jul 02 13:27:20 (seen via HDMI) Jul 02 13:27:40 hmm Jul 02 13:28:05 flasher should only appear when booting with a flashing image Jul 02 13:28:09 IIRC Jul 02 13:28:14 ok, so do this Jul 02 13:28:18 get a 2nd card Jul 02 13:28:29 install the current debian flasher Jul 02 13:28:36 and let it reinstall debian Jul 02 13:28:42 then remove the card Jul 02 13:28:47 ssh into debian and kill MLO and uboot Jul 02 13:28:55 then you should have a system that does not boot Jul 02 13:29:08 then check your buildroot boot card Jul 02 13:29:11 and try with that Jul 02 13:29:21 * av500 curses that stupud emmc Jul 02 13:29:30 ok, will try that. than for your help Jul 02 13:29:38 thanx Jul 02 13:29:55 np Jul 02 13:30:44 av500: just to be sure, you mean http://beagleboard.org/latest-images Jul 02 13:31:52 yes Jul 02 13:31:58 just to get into a know good state Jul 02 13:32:20 but you need a flasher image Jul 02 13:32:21 OR Jul 02 13:32:25 you get the SD card image Jul 02 13:32:29 boot into thaT Jul 02 13:32:31 boot into that Jul 02 13:32:36 and kill MLO on the emmc from there Jul 02 13:32:40 you might need to mount it Jul 02 13:32:43 manually Jul 02 13:33:25 I'll start with reflashing debian first Jul 02 13:37:14 Hi I am looking for antenna wifi for beagle anybody knows which one can I use? Jul 02 13:38:55 TEPTO: I like the one that Logic Supply sells: http://www.logicsupply.com/blog/2014/07/18/beaglebone-black-wifi-adapter-installation-updated-tutorial/ Jul 02 13:45:36 @jkridner I think they don't have them any more, that is why im looking for an alternative Jul 02 13:46:01 says in-stock at http://www.logicsupply.com/components/networking/wireless/uwn200/ Jul 02 13:48:55 ok thank you I used to buy the cape and the boxes there but they don't have them any more so I though the antennas neither Jul 02 13:51:50 you know where can I buy the boxes? Jul 02 13:55:19 do you need that same design? Jul 02 13:55:40 I guess I could see if someone else would do it, but there are a ton of other cases out there. Jul 02 14:09:36 if yu can find it would b e great Jul 02 14:09:55 Another option for antenna? Jul 02 14:10:31 antenna? Jul 02 14:10:50 you can google for USB wifi sticks just as well as we can Jul 02 14:17:44 I think not all of the wifi antenas works for Beagle bone Jul 02 14:40:08 hello Jul 02 14:45:54 anyone can help with stdatomic.h Jul 02 14:46:06 can anyone help with stdatomic.h Jul 02 14:48:30 what about it? Jul 02 14:49:02 av500: It worked without reflashing debian. I've written the SD from my debian machine instead of the colleague's virtualbox VM Jul 02 14:49:23 now struggling with ssh into dropbear (ping is working)( Jul 02 14:50:50 trying to get it on the beaglebone Jul 02 14:51:10 http://clang.llvm.org/doxygen/stdatomic_8h_source.html, got this link Jul 02 14:52:01 but not sure how to get it on beaglebone, or where on beaglebone it should go Jul 02 14:52:29 ibrahim: why don't you just install a proper toolchain that brings along the headers it needs? Jul 02 14:52:49 I install clang Jul 02 14:53:11 in which version? Jul 02 14:53:33 zino_: good Jul 02 14:53:50 that I am not sure, I used sudo apt-get install clang Jul 02 14:54:36 av500: now is getting frustrating: I'm so close I can almost smell it:) Jul 02 14:56:15 please need help on this really bad Jul 02 14:57:46 ibrahim: find out the version first. Jul 02 15:46:15 invalid value 'gnu11' in '-std=gnu11' dose anyone know how to resolve an issue like this Jul 02 16:10:59 rcn-ee: so the mt7601, e.g. TP-Link TL-WN727N showing up as 148f:7601 Ralink Technology .... isn't really "working" yet I take it? Jul 02 16:11:41 using a driver from Debian Jessie, not compiled anyhow, got mt7601Usta loaded Jul 02 16:18:13 lol, I see in 3.19+ there is a brand new community-based driver for it Jul 02 16:19:55 Spirilis, it hasn't entered mainline yet (4.2-rc merge) Jul 02 16:20:15 yep, but it's available on a github site I guess. is it worth trying to compile that on a 4.1 kernel? Jul 02 16:21:21 i think so, untested.. Jul 02 16:21:31 gotcha ... I'll try and give it a roll Jul 02 16:22:41 Spirilis, did you install the modules: sudo apt-get install mt7601u-modules-`uname -r` Jul 02 16:22:48 yep Jul 02 16:23:02 that's what I was using to test (running 3.8 at the time) Jul 02 16:27:04 invalid value 'gnu11' in '-std=gnu11' can anyone help with this issue Jul 02 16:27:20 error: invalid value 'gnu11' in '-std=gnu11' Jul 02 16:29:46 ibrahim: thats why i told you to check the version. it might be that your compiler just doesn't know about c++11 so far. Jul 02 16:29:52 * LetoThe2nd sighs and is gone again Jul 02 16:31:09 I installed clang++ Jul 02 16:32:20 for other version... keep getting- Couldn't find any package by regex 'clang-3.5' Jul 02 16:39:31 sweet, got a wlan0 interface rolling with 4.4.1-bone9 Jul 02 16:39:36 now time to see if it works :) Jul 02 16:39:40 4.1.1-bone9 even Jul 02 16:40:54 ok, ifconfig wlan0 up and then iwlist wlan0 scan returns some ESSID's along with a bunch of unknown fields Jul 02 16:42:46 Spirilis, nice, the 4.1.x branch will be around for awhile, we are using that as the 3.8 replacement.. Jul 02 16:43:12 sweet :) Jul 02 16:43:38 I think the main reason I backed down to 3.8 was for bone_capemgr and enabling SPI support Jul 02 16:44:14 looks like bone_capemgr exists in 4.1.1 but IIRC things are a little different with the devtree files? Jul 02 16:56:06 Spirilis, a little, just follow the readme.md for hints. ;) Jul 02 18:29:24 Hi I am programming a beaglobone black with interface in VB.net Jul 02 18:30:09 I wanna to have any help or asesory of the steps that I should follow Jul 02 18:30:52 that doesn't sound very much like linux Jul 02 18:31:45 I try programming in python but is very hard difficult Jul 02 18:31:52 Do intrefaces graphics Jul 02 19:14:46 hello Jul 02 19:14:57 anyone here interested in the Nim language? Jul 02 19:15:42 if yes I have built a librari to be used with beaglebone here: https://github.com/xyz32/BeagleboneBlack_GPIO_nim Jul 02 19:16:05 And because Nim compiles to C, the output can be used inside C code as well Jul 02 19:17:25 I wasn’t interested until I read about it just now Jul 02 19:18:15 it is also fast. On my own test with recursive fibonacci of 50 Jul 02 19:18:18 how well can the BBB take advantage of Nim’s parallel programming features? idk how well ARM does hyperthreading Jul 02 19:18:23 nim is 3 seconds faster then C Jul 02 19:18:33 27s to 30s Jul 02 19:19:06 I did not get to the point of parallelism yet Jul 02 19:19:20 I was bussy implementing the library Jul 02 19:20:20 Oh and BTW Nim can compile to NodeJS Jul 02 19:20:38 so the lib can be used with cloud9 as well Jul 02 23:39:50 euh Jul 02 23:39:51 hello? Jul 02 23:40:07 nice how it posts my ip, great feature :S Jul 03 00:47:05 its out to get you Jul 03 01:32:46 Hello there! Jul 03 01:37:21 So, reading the Cape Wiki I understand that the expansion signals cannot be mixed. I currently am using the Beaglebone Black, with Debian on a custom 3.8 Kernel. I'm using the Circuitco LCD7 addon, I was curious if that new Mikrobus cape expansion would allow me to also populate the secondary headers with the Wifi PlUS module. Does anyone know if that would cause issues? Jul 03 01:38:05 I cannot find any documentation on which signals are used, and which can be mixed (if any). Thank you. **** ENDING LOGGING AT Fri Jul 03 02:59:58 2015
