**** BEGIN LOGGING AT Mon Sep 29 02:59:58 2014 Sep 29 04:17:17 i love it, china is getting a taste of the occupy movement Sep 29 04:17:29 too bad it will have even less effect there than it did here :/ Sep 29 06:46:27 hi, i wish to show the to change the boot option from blank to text mode. i did change the cmdline option in /boot/uEnv.txt from clear to text but nothing happend. is there a different location where uEnv.txt is located ? Sep 29 06:46:41 Iam using ubuntu 14.04 and Beaglebone Black Sep 29 09:35:30 hi i am trying to connect beaglebone blck as usb mass storage to tv and audio system but none of them is recognizing it Sep 29 09:35:42 can somebody help me? Sep 29 09:38:16 ? Sep 29 09:38:23 ani_: that might be because it takes quite long between powering it up and the usb mass storage device appearing Sep 29 09:38:33 also rule 1: bring patience Sep 29 09:38:58 I am powering it using external power supply Sep 29 09:39:05 have you tried powering it through the barrel connector and only attaching it once it's booted? Sep 29 09:39:41 is there any kind of utility or command or setting? Sep 29 09:39:43 yes Sep 29 09:40:12 dmesg gives me CAUTION: musb: Babble Interrupt Occurred Sep 29 09:40:16 ok, then let's approach this differently: what are you trying to achieve? Sep 29 09:41:32 i just want to put some file on external mmc and change them over the period automatically, my tv does not have hdmi port but it recognizes usb Sep 29 09:42:13 any other approach to do so? Sep 29 09:43:07 changing the file would require you to disable usb mass storage mode, mounting it locally on the BBB, changing the file, unmounting, enabling mass storage mode Sep 29 09:43:45 if that works for you, then while a bit convoluted, this would probably work Sep 29 09:44:03 I have no issues doing that Sep 29 09:44:10 what OS are you running on the BBB? Sep 29 09:44:44 but the problem is my tv or any other similar device does not detect it as a mass storage device Sep 29 09:45:20 does a Laptop show you the mass storage device? Sep 29 09:45:25 armstrong ubuntu 14.04 and debian I tried with all Sep 29 09:45:26 didnt we have that last week already? Sep 29 09:45:32 yes the laptop shows Sep 29 09:45:41 ani_: did you disable everything that is not mass storage on teh bbb? Sep 29 09:45:57 there is no armstrong ubuntu. there is either angstrom OR ubuntu Sep 29 09:46:08 yes Koth but the issue remains the same Sep 29 09:46:22 wth.. there is an "armstrong ubuntu"? Sep 29 09:46:42 you must disable the composite device and only enable mass storage mode Sep 29 09:46:49 ani_: ok, get a beagle480 and debug the connection process Sep 29 09:46:55 Yes I know armstrong , ubuntu , debian Sep 29 09:46:57 ani_: most likely your tv is doing something weird Sep 29 09:47:03 ani_: anström! Sep 29 09:47:07 angström Sep 29 09:47:11 * KotH should learn to type Sep 29 09:47:25 ok thanks for the suggestion Sep 29 09:47:29 ani_: linux neither has a bicycle nor does it take doping Sep 29 09:47:55 i tried the same thing with multiple tvs Sep 29 09:48:24 from the same manufacturer? Sep 29 09:48:29 different manufacturers? Sep 29 09:48:33 differnt OS? Sep 29 09:48:39 different sony and lg Sep 29 09:49:05 ani_: _first_ disable the composite device≤ Sep 29 09:50:42 ok and then next Sep 29 09:51:33 hey tbr if please help me out if u know this i have spent almost a week on this Sep 29 09:51:33 09:46:42< tbr> you must disable the composite device and only enable mass storage mode Sep 29 09:51:48 ani_: is this work or home project? Sep 29 09:51:49 ok i will try this again ad let u know Sep 29 09:52:52 i am doing it as uni project Sep 29 09:53:29 then the journey is the goal and we're here to help you, but certainly not do do your assignments. Sep 29 09:53:59 hm at least he get the clue to ask here instead of telling the mentor it is not possible Sep 29 09:54:33 * KotH wouldnt be surprised if mentor answered with "make it possible" Sep 29 09:54:55 at university? Sep 29 09:55:02 hahahaaa lol Sep 29 09:55:15 the mentor might know it's possible :) Sep 29 09:55:23 hahahhahaha lol Sep 29 09:55:50 i have created a hotspot and deployed a small server on it but i want to achieve this anyhow Sep 29 09:56:04 woglinde: we are talking indian universities... the guys who send a probe to mars on a budget! Sep 29 09:56:26 ani_: what exactly is your goal? achieve what? Sep 29 09:56:26 KotH and? Sep 29 09:56:41 this usb related stuff Sep 29 09:57:43 ? Sep 29 09:57:45 i am creating a completely automated digital device which can work on anything Sep 29 09:57:53 ?? Sep 29 09:58:55 ani_: please try again without the buzz words, thanks Sep 29 10:01:14 ok thanks KotH Sep 29 10:05:11 Hi at all, somebody have experience to build a custom RFS with OpenEmbeded (Yoctoproyect), Sep 29 10:05:22 FRS? Sep 29 10:05:24 RFS? Sep 29 10:05:35 also, #yocto Sep 29 10:05:52 root filesystem Sep 29 10:05:59 complete Sep 29 10:06:31 get angstrom script, read documentation, …, profit! Sep 29 10:07:57 I know, but I want build a minimal systemd-image, because I have tried to mount this RFS over RAM Sep 29 10:08:31 yocto actually has really nice documentation, including on how to use systemd instead of an other init system Sep 29 10:08:31 to avoid corruption micro-SD Sep 29 10:08:43 minimal? systemd? i think you misunderstood something Sep 29 10:08:58 and there is meta-ti, which should give you the necessary add-ons. Sep 29 10:09:06 oteros2000: but what LetoThe2nd, tbr and av500 said Sep 29 10:09:35 Lol. Here w e go Sep 29 10:09:45 Swiss troll Sep 29 10:10:02 oteros2000: as said, there is yocto documentation Sep 29 10:10:03 * KotH hits Andrew_ with a 10kg bar of toblerone Sep 29 10:10:10 most people switched to Debian on BBB Sep 29 10:10:29 And some switched from Bibb Sep 29 10:10:30 I use Angstrom, Sep 29 10:10:43 Due to the silly supply Sep 29 10:11:00 angst-rom has nice minimal recipes, what are you missing? Sep 29 10:11:27 and as angst-rom is yocto compatible, where's the problem? Sep 29 10:12:30 +1 Sep 29 10:13:11 Baking powder Sep 29 10:13:15 fine I'm looking for this documentation Sep 29 10:14:49 oteros2000: angstrom, oe and yocto have quite some docs online Sep 29 10:15:02 there are also IRC channels for oe and yocto AFAIK Sep 29 10:15:21 here is not the best place for oe help, since BBB moved to debian Sep 29 12:55:53 hi guys i have a question. I installed gentoo on my beaglebone black. I pulled the latest kernel which was 3.14 and all the beaglebone specific patches. I can boot my bealgebone black fine. but I am not able to find a bone.capemgr directory under /sys/devices I have the argus manager compiled into the kernel as well as the beaglebone black helper I saw Sep 29 12:56:23 how does handling overlays work with the newer kernel work? Sep 29 13:11:30 have you applied pantos dt overlay patches too? Sep 29 13:11:33 overlays are not mainline Sep 29 13:11:40 they were in angstrom for a while Sep 29 13:11:48 they are still being discussed Sep 29 13:14:12 and will be for the forseeable future Sep 29 14:00:42 av500, so how does one go about handling the pins at this point if running a mainline kernel? Or it is better to just build a 3.8 kernel? Sep 29 14:03:48 KotH, no i have not applied that patch. does it work for the mainline kernel? Sep 29 14:03:52 mistawright: with DT Sep 29 14:03:56 but there are no overlays Sep 29 14:04:11 so you need the right DT at boot Sep 29 14:05:51 av500, so currently there is no way i could load an overlay on the fly as I am used to? Dont mind having to do it at boot Sep 29 19:09:36 Can the BBB write to the SD card at ~40MBs ? Sep 29 19:11:16 Can yourSD card accept data at ~40MB/s? Sep 29 19:17:43 Yes Sep 29 19:17:50 but that doesnt mean the BB can write that speed Sep 29 19:17:52 Really. Sep 29 19:17:55 is there any information about this ? Sep 29 19:17:59 Some cards can do 80 Sep 29 19:17:59 [citation needed] Sep 29 19:18:13 http://www.tomshardware.com/charts/microsd-cards-2014/-2-Sequential-Write-MB-s,3481.html Sep 29 19:18:39 HoloPed: In answer to your initial question, I think so. Try it and see. Sep 29 19:19:01 I dont have a card yet, I wanted to know before I buy one Sep 29 19:19:31 Do you have a need to actually write data that fast to the SD card? Sep 29 19:19:46 Or do you really just like big numbers? ;-P Sep 29 19:21:36 yes, I actually need Sep 29 19:21:47 I need to sample two 5mp cameras, machine vision camera Sep 29 19:21:49 once a second Sep 29 19:21:54 and write the image Sep 29 19:22:06 now I can either write it raw or compressed Sep 29 19:22:27 and I don't know if the BBB can compress two 5mp images in less than a second Sep 29 19:23:01 What interface are you bringing in the image data over? Sep 29 19:23:09 Probably usb Sep 29 19:23:29 (and raw data there would be 10MB, assuming 8-bit monochrome) Sep 29 19:23:41 one is monocrome, one is RGB Sep 29 19:23:45 ...does the USB subsystem have the bandwidth for that? Sep 29 19:23:55 another good question Sep 29 19:24:08 OK, so, then 20MB/s, again assuming 8-bit channels. Sep 29 19:24:19 is 10mb per chamera ? Sep 29 19:24:22 why Sep 29 19:24:24 ...no Sep 29 19:24:42 5MP * 1 byte per pixel monochrome = 5MB. Sep 29 19:24:47 yes Sep 29 19:24:51 and 15mb for the color Sep 29 19:24:55 5MP * 3 channels * 1 byte per channel = 15MB Sep 29 19:25:05 thats 20MB for 1 FPS Sep 29 19:25:06 5MB + 15MB = 20MB Sep 29 19:25:15 Ideally I would want 2 fps Sep 29 19:25:26 but I will settle for 1 Sep 29 19:25:31 Well, you said your operating rate was "less than a second", which yields 1fps. Sep 29 19:25:59 Because you have image acquisition, processing, and write-out that needs to happen for a frame. Sep 29 19:26:07 yes Sep 29 19:26:13 OK, so, 2fps is your 40MB/s Sep 29 19:26:20 so some cameras can compress in cam, but they are expensive Sep 29 19:26:31 Not really. Sep 29 19:27:16 for the good ones, I need C-mount or CS Sep 29 19:27:17 Most webcams and security cameras produce BMP or JPG natively for single-frame captures. Sep 29 19:27:29 yes, but these cameras are more than webcams, Sep 29 19:27:50 What vendor are you getting your cameras from? Sep 29 19:28:00 AVT? Basler? Sep 29 19:28:04 I'm looking at IDS, pointgrey Sep 29 19:28:11 (Point Grey? JAI? IDS?) Sep 29 19:28:15 Ah. Sep 29 19:28:16 JAI, yes Sep 29 19:28:27 Eh. Sep 29 19:28:49 Global shutter is another requirment, which cuts down the options Sep 29 19:28:53 * agmlego has not been impressed with most of the JAI stuff he has worked with. Sep 29 19:29:03 why ? Sep 29 19:29:31 was looking at this Sep 29 19:29:32 http://1stvision.com/cameras/JAI/GO-5000M-PMCL-GO-5000C-PMCL.html Sep 29 19:29:41 They are not terribly well-built, and their API sucks. Sep 29 19:29:49 * agmlego strongly prefers AVT. Sep 29 19:30:06 And I guess if you must have USB, the Basler ace is OK. Sep 29 19:30:10 I like PGR, but they have very little global shutter Sep 29 19:30:21 I just have issues with the way Basler does business. Sep 29 19:30:30 I see Sep 29 19:30:33 so back to the BBB Sep 29 19:30:36 HoloPed: I do machine vision for a living. ;-P Sep 29 19:30:37 do you think it is up to it ? Sep 29 19:30:43 cool :) me too Sep 29 19:30:44 Up to what? Sep 29 19:30:55 but i'm more on the software side Sep 29 19:31:06 capture/write Sep 29 19:31:14 either raw or compressed Sep 29 19:31:19 And nothing else? Sep 29 19:31:23 nothing else Sep 29 19:31:28 Kind of boring, but OK. Sep 29 19:31:32 the rest will happen offline Sep 29 19:31:40 HoloPed: Short answer? Try it and see. Sep 29 19:31:47 yeah :) thats what I thought Sep 29 19:31:53 HoloPed: Longer answer? Go get all the hardware...and try it. Sep 29 19:31:54 I was also looking at the UDOO Sep 29 19:32:04 HoloPed: Long answer? Probably. Sep 29 19:32:51 (actually, long answer is, look at the TRM and board designs, and see whether all the components used together will produce the bandwidths you need) Sep 29 19:33:03 But I assumed you did that already. Sep 29 19:33:25 i'm not a hardware guy, so that can be hard for me Sep 29 19:33:33 Ah. Sep 29 19:33:41 Then the asnwer is to try it and see. Sep 29 19:33:44 but testing - that I can do Sep 29 19:33:49 maybe help me choose a camera ? Sep 29 19:33:51 Or, pay someone else to do so. ;-P Sep 29 19:33:59 HoloPed: Choose how? Sep 29 19:34:02 havving a hard time finding the suitable model Sep 29 19:34:25 so it needs to be: global shutter, about 5mp, light weight Sep 29 19:34:44 OK, let us break this down. Sep 29 19:34:55 1. Global shutter- why? Sep 29 19:34:58 these cameras will be flying Sep 29 19:35:02 2. "About" 5MP? Sep 29 19:35:14 on a quadcopter Sep 29 19:35:15 3. "Light weight"? 100g? 200g? 10g? Sep 29 19:35:25 camera + lens < 300g Sep 29 19:35:51 4. Presumably you still must have USB. Sep 29 19:36:04 5. Camera must be capable of a minimum of 2fps. Sep 29 19:36:11 6. Camera must be C-mount. Sep 29 19:36:32 or CS-mount Sep 29 19:36:47 Fortunately you have budget available, so getting these is not that big a deal. Sep 29 19:37:07 Gige cameras also ok, if they can be sampled over 100m port Sep 29 19:37:18 budget exists, yes Sep 29 19:37:30 Sure can, but remember, the cameras you are looking at are industrial cameras and nearly universlaly run on 24VDC. Sep 29 19:37:37 (or PoE) Sep 29 19:37:46 right Sep 29 19:37:48 good point Sep 29 19:38:00 So be prepared to supply that if you go the GigE route. Sep 29 19:38:16 that is possible, but usb is much prefered Sep 29 19:39:14 So, from my experience, I would recommend the Basler acA2500-14u{c,m}. Sep 29 19:39:54 5MP, C-mount, USB3.0, 14fps, CMOS sensor, 80g. Sep 29 19:40:17 Ooh, but Basler did not use the Aptina layout that allows global shutter. Sep 29 19:40:20 Never mind. Sep 29 19:40:38 sad Sep 29 19:41:06 Well, now you know which questions to ask the various camera configurators. Sep 29 19:42:13 yup Sep 29 19:42:27 thanks ! Sep 29 19:42:38 (you are probably going to find it difficult to find USB industrial cameras, for reference) Sep 29 19:42:46 I know Sep 29 19:42:46 Because USB sucks, a lot. Sep 29 19:42:54 I know that too Sep 29 19:42:56 For the same reasons IEEE1394 sucked. Sep 29 19:43:05 god I hate firewire Sep 29 19:43:12 So, while it is the right solution in your case... Sep 29 19:43:25 ...that requirement severely limits your options. Sep 29 19:43:34 I noticed Sep 29 19:43:37 also global shutter Sep 29 19:43:38 Now, if we waived that... Sep 29 19:44:53 Also, how tight is the 5MP restriction? Sep 29 19:44:59 not tight Sep 29 19:45:10 this is a proof of concept phase Sep 29 19:45:11 OK, then. Sep 29 19:45:26 i'm flexible on almost everything Sep 29 19:45:41 Allied Vision Technologies' Mako G-419{B,C} Sep 29 19:45:56 4MP CMOS, global shutter, 26fps. Sep 29 19:46:09 80g. Sep 29 19:46:25 square sensor ? Sep 29 19:46:27 12-24VDC power, or 802.3af-compliant PoE. Sep 29 19:46:27 intersting Sep 29 19:46:29 Sure. Sep 29 19:46:32 Why not? Sep 29 19:46:40 Was not one of the restrictions. ;-P Sep 29 19:46:43 not complaning Sep 29 19:48:01 Do they have linux drivers ? Sep 29 19:48:30 Their API runs on Linux, yes. Sep 29 19:48:51 If you can withstand the wieght, the Manta G-504{B,C} are also good cameras. Sep 29 19:48:57 With a more conventional sensor. Sep 29 19:49:27 that one is probably too heavy Sep 29 19:49:47 what is the sensor size Sep 29 19:49:52 what does type 1 mean' Sep 29 19:50:04 The Mako will probably be in the ballpark of US$2100 apiece; the Mantas are a little more at US$2750. Sep 29 19:50:08 1" sensor. Sep 29 19:52:50 ok Sep 29 19:52:55 I have a lot to process Sep 29 19:52:57 (these of course being list prices; you may be able to negotiate better) Sep 29 19:53:01 Yup. Sep 29 19:53:14 what kind of machine vision do you do ? Sep 29 19:53:24 Industrial automation. Sep 29 19:53:43 Mostly gauging, assembly verification, auto ID, and robot guidance. Sep 29 19:54:06 We made the front cover of Vision System Design a couple months ago. Sep 29 19:55:04 nice Sep 29 19:55:07 June 2014 edition, apparently. Sep 29 19:55:38 Mostly automotive, being in the Detroit area. Sep 29 19:55:49 I'm in London, On Sep 29 19:55:56 But we get into aerospace and food processing. Sep 29 19:56:05 practically neighbors Sep 29 19:56:07 Ah, heh, some of our customers are out that way. Sep 29 19:56:30 What types do you do? Sep 29 19:56:56 computer vision stuff, mostly gesture recognition, people tracking Sep 29 19:57:02 Ah. Sep 29 19:57:07 Squishy stuff. ;-P Sep 29 19:57:12 but this new project is more about stiching and 3d reconstruction Sep 29 19:57:15 yes Sep 29 19:57:17 squishy Sep 29 19:57:55 * agmlego very much prefers to stick with the absolutely-controlled industrial environments, thankyouverymuch. ;-P Sep 29 19:58:02 I know the feeling Sep 29 19:58:41 * agmlego is also very happy to report vision systems happily chugging away at 6 nines. Sep 29 19:59:06 I'm happy if it works 80% of the time Sep 29 19:59:17 Heh. Sep 29 19:59:21 Different worlds. Sep 29 19:59:25 totaly Sep 29 19:59:29 industrial vision systems are pretty cool. Sep 29 19:59:30 I have to deal with sunshine Sep 29 19:59:32 clouds Sep 29 19:59:35 gloves Sep 29 19:59:43 buses Sep 29 19:59:45 you name it Sep 29 20:00:03 Need some computer vision people ? Sep 29 20:00:09 my wife has a PHD in it Sep 29 20:00:18 I get to deal with coolant, induction furnaces, forktruck drivers, and third-shift poorly-paid employees who like how their nail polish looks under the lights. Sep 29 20:00:28 haha Sep 29 20:00:42 HoloPed: Um, maybe. Lake Orion is one hell of a commute from London. Sep 29 20:00:58 remote :) Sep 29 20:01:06 Not so much. Sep 29 20:01:17 Physical hardware is hard to remotely build. ;-P Sep 29 20:01:25 yes Sep 29 22:16:49 I've been using the BBB with an Ubee Stick USB modem, and was experiencing intermittent freezes with an Ubuntu built off of the Linux 3.8 kernel, a la: https://groups.google.com/forum/#!topic/beagleboard/Nu5by49rQ6w Sep 29 22:18:54 I'm now using the latest Ubuntu Precise rootfs from http://www.armhf.com/download/ , which is kernel version 3.14.*, and I'm still experiencing the freezing issue. Sep 29 22:20:13 I have reason to believe it is USB related, and I was wondering if anyone else who was having this issue with the 3.8 kernel was able to resolve it, and with what version of the kernel. Sep 30 02:45:25 hi all **** ENDING LOGGING AT Tue Sep 30 02:59:58 2014
