Feb 25 05:11:28 <Ayyappa> hi all
Feb 25 05:14:47 <snowstaff> Hello everyone! Who has worked with manchester code on PRU?
Feb 25 08:52:57 <SAK> hey guys i am back. I am trying to compile a simple code of opencv to convert colors of src image. i get this error at cvtColor method http://pastebin.com/s0Y1iY6D
Feb 25 08:53:14 <SAK> same code works on my machine. but not in beagle bone
Feb 25 08:53:46 <SAK> veremit if you can look into this. should i do kernel build for it
Feb 25 08:53:46 <SAK> ??
Feb 25 09:13:53 <tbr> is that some sort of TI patched openCV?
Feb 25 09:14:28 <SAK> it is simple opencv
Feb 25 09:14:32 <SAK> not TI patched
Feb 25 09:14:50 <SAK> i followed this link http://indranilsinharoy.com/2012/11/01/installing-opencv-on-linux/
Feb 25 09:14:55 <SAK> but with opencv 3.0.0
Feb 25 09:16:14 <tbr> so why does it ask for cmem, which seems to be a TI thing
Feb 25 09:17:19 <SAK> i got this issue couple of days ago and thought i need to kernel build my stuff
Feb 25 09:17:55 <veremit> cmem is a ti shared mem thing
Feb 25 09:18:03 <veremit> no idea why you need to use it
Feb 25 09:18:19 <tbr> so why would vanilla opencv try to use it?
Feb 25 09:18:25 <SAK> but it never worked. i got stuck at point where all LEDs lit solid and i had to start over again
Feb 25 09:18:51 <veremit> yeah you crashed it lol
Feb 25 09:18:58 <veremit> very possiblewith shared mem lol
Feb 25 09:19:09 <tbr> I'd abandon the whole cmem idea
Feb 25 09:19:12 <veremit> me2
Feb 25 09:19:26 <SAK> i am not even considering this cmem
Feb 25 09:19:29 <tbr> make sure to build opencv in a way that it doesn't think it needs cmem
Feb 25 09:19:30 <SAK> but it comes from nowhere
Feb 25 09:19:39 <SAK> ok
Feb 25 09:21:05 <tbr> refer to the opencv documentation on how to do this
Feb 25 09:21:11 <SAK> sure
Feb 25 09:21:15 <tbr> I suspect it's one of the CMAKE options
Feb 25 09:22:28 <SAK> yes i am drilling it down
Feb 25 09:22:32 <SAK> thanks for pointer :)
Feb 25 09:31:09 <Strontium> zmatt: I saw the earlier conversation about More USB ports for BBB.  As it turns out im designing the smallest and cheapest possible hub specifically for the BBB to give it 4 USB ports. http://imgur.com/a/xnqsl
Feb 25 09:38:59 <veremit> usb2504 gives you 4 ports iirc
Feb 25 09:39:08 <veremit> usb2507 .. gives you 7.
Feb 25 09:39:21 <veremit> both available via microchip now :) used both.
Feb 25 10:07:33 <Strontium> veremit: theres barely enough space for 4 ports, let alone 7.
Feb 25 10:07:44 <veremit> :]
Feb 25 10:07:45 <Strontium> Plus im trying to keep the price and size down.
Feb 25 10:08:39 <Strontium> I had thought about one with Type C connectors.  That might fit 7.  But Type C cables are not so common nyet.
Feb 25 10:08:53 <Strontium> But it would still be more expensive.
Feb 25 10:55:57 <snowstaff> I have one trouble: i am using PRU1 and i try to write byte to C25, but nothing has changed. I can only read c25 from PRU1.
Feb 25 14:24:54 <Yurion> Good afternoon gentleman.
Feb 25 14:25:25 <dwery> hello. I remember I saw a small and simple C library to handle gpios.. but I can't find the link :( any clues?
Feb 25 14:26:29 <Yurion> Is there anybody who is willing to advise me on debian published here?
Feb 25 14:33:25 <av500> DJW|Home: here: http://www.cnx-software.com/2016/02/25/gpd-win-windows-10-portable-gaming-console-launched-on-indiegogo-for-299/
Feb 25 14:43:14 <Bastiaan> How can I solder a QFN package what kind of materials do I need?
Feb 25 14:47:03 <chanakya_vc> Hello everyone. I am interested in participating in this year's GSOC  and I am really interested in the idea about  Co-processor support in open source operating systems.
Feb 25 14:48:38 <chanakya_vc> I have a few doubts regarding the same.Does the project expect, for example, just writing a library for enabling UART communication between Arduino and BeagleBone?
Feb 25 14:49:31 <chanakya_vc> Could someone please help me?
Feb 25 14:50:13 <av500> Bastiaan: soldering iron?
Feb 25 14:50:34 <av500> chanakya_vc: sign up to the mailing list
Feb 25 14:51:16 <av500> Bastiaan: and a youtube capable device: https://www.youtube.com/results?search_query=solder+qfn
Feb 25 14:53:15 <chanakya_vc> av500 : I did to the BeagleBone mailing list,unless there is some different list for GSOC? I did ask on that but I did not receive any response.
Feb 25 14:55:01 <av500> chanakya_vc: there is a beagle-gsoc list
Feb 25 14:55:47 <av500> https://groups.google.com/forum/#!forum/beagleboard-gsoc
Feb 25 14:57:24 <Bastiaan> yeah I am using the chipqick and soldering Iron, for some reason the pins dont stick to the board... is it possible that there is a different size in simular packages?
Feb 25 14:58:02 <av500> what part?
Feb 25 15:00:39 <chanakya_vc> av500: Yes I am already signed up to this mailing list.I will ask again on this list.
Feb 25 15:02:33 <av500> chanakya_vc: the list is moderated, I just approved your posts
Feb 25 15:07:46 <chanakya_vc> av500: I did not know that. Thanks a lot!! So any new question that I post will also have to approved?
Feb 25 15:09:23 <av500> not sure
Feb 25 15:13:35 <chanakya_vc> av500:Thanks anyway. Will ask on the list.
Feb 25 15:55:44 <chanakya_vc> av500:Please check if you would have to approve my new post? Really sorry to bother you.
Feb 25 16:01:20 <av500> chanakya_vc: what is your email?
Feb 25 16:01:30 <av500> ah
Feb 25 16:01:32 <av500> I see the post
Feb 25 16:02:37 <chanakya_vc> av500:vaibhav96.india @gmail.com
Feb 25 16:04:43 <av500> chanakya_vc: yes
Feb 25 16:07:54 <alexhiam> chanakya_vc: just posted some more info on that thread
Feb 25 16:09:30 <philenotfound> anyone still has a VGA cape and want to part with it?
Feb 25 16:10:18 <alexhiam> av500, jkridner: perhaps we should pin a new first steps for prospective students message on the ml
Feb 25 16:10:42 <jkridner> well, let's be sure they are on the ideas page too.
Feb 25 16:10:52 <alexhiam> oh, good point...
Feb 25 16:11:02 <chanakya_vc> av500: I really did not get what you are saying?
Feb 25 16:11:34 <alexhiam> jkridner: I guess it is
Feb 25 16:11:52 <chanakya_vc> alexhiam:I did post again on the list.Had some doubts.
Feb 25 16:15:39 <alexhiam> chanakya_vc: Vaibhav Choudhary on the mailing list?
Feb 25 16:31:00 <chanakya_vc> alexhiam: Yes
Feb 25 16:31:39 <chanakya_vc> alexhiam:Thanks!
Feb 25 18:50:57 <Donna> help
Feb 25 18:51:23 <Guest78885> I am trying to buy a beagleboard
Feb 25 18:51:51 <Guest78885> but my order has been canceled through AVNET
Feb 25 18:52:27 <Guest78885> I need a number to call to tlak to someone about the order
Feb 25 18:59:04 <anuja> hello
Feb 25 18:59:09 <anuja> anyone there?
Feb 25 18:59:50 <anuja> i have question regarding C programming of beaglebone black
Feb 25 19:00:30 <jkridner> Guest78885: stick around a bit after asking your f-ing question.
Feb 25 19:00:36 <jkridner> :(
Feb 25 19:00:56 <jkridner> I mean, there's a phone number right on http://beagleboard.org/about for **** sake.
Feb 25 19:03:50 <KotH> jkridner: you need more chocolate in your life :)
Feb 25 19:03:57 <jkridner> _1
Feb 25 19:03:58 <jkridner> +1
Feb 25 19:04:12 <anuja> hello
Feb 25 19:04:16 <jkridner> KotH: -o?
Feb 25 19:04:24 <KotH> i dont like to stick out
Feb 25 19:04:28 <jkridner> :-D
Feb 25 19:04:31 <KotH> i can always get +o when i need it :)
Feb 25 19:04:43 <mwillbanks> With jessie, is there a change that makes it so that the /etc/ssh/ssh_host* keys are not being regenerated?
Feb 25 19:04:48 <KotH> (which is quite rare these days
Feb 25 19:04:54 <jkridner> anuja: read http://beagleboard.org/chat regarding how to ask smart questions.
Feb 25 19:05:12 <KotH> mwillbanks: have a look at /var/log/auth.log
Feb 25 19:05:28 * jkridner hasn't been on IRC as much as desired lately. coming back to it in a bad mood I guess.
Feb 25 19:05:35 <KotH> mwillbanks: it might also be that your client side rejects the key, if you still have a dsa key
Feb 25 19:06:02 <KotH> jkridner: it's never a good idea to join a user support channel when yoou are in a bad mood
Feb 25 19:06:12 <jkridner> :-D
Feb 25 19:06:23 * KotH doesnt want to know how many unsuspecting DAUs suffered under his mood
Feb 25 19:06:30 <jkridner> you mean this isn't a vent channel? :-)
Feb 25 19:06:34 <mwillbanks> KotH i think you might be misunderstanding, basically, if i were to flash the device previously and add a ssh.regenerate into /etc/ssh/ it would create all of the associated keys for the host
Feb 25 19:06:45 <mwillbanks> after moving to jessie this no longer happens
Feb 25 19:06:46 <KotH> jkridner: it's actually quite a good vent channel ;)
Feb 25 19:07:01 <anuja> can u suggest c libraries for bbb?
Feb 25 19:07:07 <KotH> mwillbanks: uhmm.. is your / writable?
Feb 25 19:07:15 <mwillbanks> indeed it is
Feb 25 19:07:32 <KotH> hmm.. other than the obvious RTFM on ssh, i dont know what would be wrong
Feb 25 19:07:52 <KotH> anuja: you are aware that you are programming a unix system, are you?
Feb 25 19:08:25 <mwillbanks> KotH yeah, well, i can always reconfigure openssh-server but i'll dig deeper for wherever this changed.
Feb 25 19:09:35 * KotH goes *poof*
Feb 25 19:09:45 * jkridner reboots beagleboard.org webserver to try to resolve an openid issue.
Feb 25 19:10:27 <anuja> KotH: yes ! but i want to use cross-compiler and do bare-metal programming for BBB
Feb 25 19:10:39 <mwillbanks> whoa - dpkg format database was corrupted.  that's a new one :)
Feb 25 19:13:44 <alexhiam> anuja: you're probably looking for starterware
Feb 25 19:14:23 <anuja> ok. is CCS available for free?
Feb 25 19:14:37 <alexhiam> yeah, but it's code size limited I believe
Feb 25 19:18:55 <anuja> ok. what is the solution for the limited code size of CCS?
Feb 25 19:19:21 <alexhiam> money
Feb 25 19:19:44 <alexhiam> it's only a problem if it ain't enough for your application
Feb 25 19:20:10 * jkridner just noticed BeagleBot is blocked lately w/o SASL
Feb 25 19:20:29 <alexhiam> what bot do you use jkridner?
Feb 25 19:20:38 <jkridner> pircbot
Feb 25 19:20:44 * alexhiam just started playing with sopel
Feb 25 19:20:55 <jkridner> USER PircBot 8 * :PircBot 1.4.6 Java IRC Bot - www.jibble.org
Feb 25 19:21:08 <alexhiam> java?! yucky
Feb 25 19:22:54 <anuja> okay.thank you.
Feb 25 19:30:30 <zmatt> ew
Feb 25 19:34:12 <nerienna> zmatt I found the two lines that define the 1000MHz
Feb 25 19:34:32 <nerienna> and I found a patch that assumes Board is Beaglebone
Feb 25 19:35:19 <nerienna> you told me, where to look for something like that
Feb 25 19:35:25 <nerienna> thx
Feb 25 19:36:16 <zmatt> yeah if you comment out those two lines it should pay attention to eFUSE even if the board is considered to be a BBB
Feb 25 19:37:36 <nerienna> yes, and with the patch, uboot assumes the board is a BBB if it finds nothing
Feb 25 19:48:39 <zmatt> if your board is sufficiently close to the BBB that might still make sense though
Feb 25 19:54:00 <nerienna> it is close
Feb 25 19:54:54 <nerienna> doesn't look that similar, but the greatest differences are other connectors and the missing hdmi
Feb 25 19:55:42 <zmatt> yeah the main thing u-boot cares about is the processor, the pmic, the ram, and your boot storage medium
Feb 25 19:56:15 <zmatt> the rest is flavoring
Feb 25 19:56:16 <zmatt> ;)
Feb 25 19:56:32 <nerienna> ok, processor is AM3357, but that changes not very much
Feb 25 19:56:50 <nerienna> just the 800MHz
Feb 25 19:56:50 <zmatt> no, AM335x is all the same to it
Feb 25 19:57:10 <zmatt> if it weren't for the weird hardcoded 1GHz rule it would have worked right
Feb 25 19:58:28 <zmatt> if your pcb layout for the DDR3L ram traces is different, then you may want to reoptimize the leveling parameters for your board
Feb 25 19:59:08 <nerienna> this part of the layout is the same
Feb 25 20:30:48 <zmatt> hmm, I should fix some breakfast/dinner/time-of-day-neutral-edible-object
Feb 25 21:19:27 <DJW|Home> av500: a rip off of a device that was 'borrowing' from more than a few devices ;). Interesting but they could have done a better job withthe mocks ;)
Feb 25 23:04:14 <dwery> hello. I remember I saw a small and simple C library to handle gpios (not via sysfs)... but I can't find the link :( any clues?
Feb 25 23:28:07 <gevans> dwery: I found one a while back but unfortunately, I didn't keep track of the URL either.
Feb 25 23:28:20 <gevans> A quick GitHub search brings up some results though: https://github.com/search?l=C&q=gpio&type=Repositories&utf8=%E2%9C%93
Feb 25 23:29:46 <dwery> gevans: ty
Feb 25 23:31:58 <dwery> https://github.com/topnotcher/beaglebone-gpio this one seems similar to what I was searching
Feb 25 23:32:55 <ZeekHuge> Hey ! my BBB asked me to do " sudo dpkg --configure -a" and it just seemes to stuck then after a lot of output...
Feb 25 23:33:09 <ZeekHuge> the lot of output is here http://pastebin.com/rDSrnTuy
Feb 25 23:33:45 <gevans> dwery: np :)
Feb 25 23:36:18 <ZeekHuge> if required, this is my BBB :root@beaglebone:~# uname -a .......... Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55 UTC 2015 armv7l GNU/Linux
Feb 25 23:37:38 <veremit> ZeekHuge: just download a new image .. don't bother with the old one unless you really need the legacy stuff.
Feb 25 23:44:45 <ZeekHuge> ohk, thank you veremit :)
Feb 25 23:45:42 <veremit> http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2015-11-03
Feb 25 23:50:03 <ZeekHuge> veremit, I am having that same image you pointed to ..?
Feb 25 23:50:20 <ZeekHuge> root@beaglebone:~# uname -r 3.8.13-bone79
Feb 25 23:50:24 <veremit> oh .. and it wants you to do what?!
Feb 25 23:50:52 <veremit> I'm sure 3.8 was deprecated .. yeah 3.(8) was deprecated a LOOONg time ago
Feb 25 23:50:52 <ZeekHuge> it asked me to " sudo dpkg --configure -a"
Feb 25 23:51:06 <veremit> 3.*18* I've seen .. but that should be *4.1* ...
Feb 25 23:51:18 <veremit> so you're not on those images, sorry :)
Feb 25 23:51:56 <veremit> owait
Feb 25 23:52:04 <veremit> maybe I'm thinking jessie .. damn you zmatt ..
Feb 25 23:52:10 <alexhiam_> the two "official stable releases" have 3.8 and 4.1
Feb 25 23:52:17 <alexhiam_> yeah, jessie is 4.1
Feb 25 23:52:42 <alexhiam_> wheezy is 3.8
Feb 25 23:52:59 <veremit> http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot_lxqt <=
Feb 25 23:53:05 <alexhiam_> stuck around because the old capemgr
Feb 25 23:53:07 <veremit> my bad .. I'ma blame zmatt squarely :D
Feb 25 23:53:14 <veremit> but he's on sid :D
Feb 25 23:53:23 <veremit> crazy nutter
Feb 25 23:53:26 <veremit> lol
Feb 25 23:53:33 <veremit> alexhiam: indeed, my bad :)
Feb 25 23:53:49 <veremit> bloody legacy software
Feb 25 23:55:30 <alexhiam_> we need this round of gsoc to get everything upstreamed to mainline!
Feb 25 23:56:05 <ZeekHuge> ahh, so what should i do now ? with this problem ?
Feb 25 23:57:24 <ZeekHuge> I cant go onto 4.1.* as i need to try PRU_framework on BBB and it has issues with 4.1.*
Feb 26 00:03:17 <ZeekHuge> veremit, as per this here https://github.com/shubhi1407/PRU-framework/issues/2 , 4.1* has got issues with remoteproc. And i need to use remoteproc.
Feb 26 00:03:37 <veremit> yeah they renamed it from remoteproc to something new
Feb 26 00:04:24 <veremit> something slightly more meaningful lol
Feb 26 00:04:40 <ZeekHuge> can i get an image of the branch pointed by RobertCNelson in that same issue ?
Feb 26 00:05:46 <ZeekHuge> or can i manually install the kernel headers for my image ? 3.8.13-bone79 ?
Feb 26 00:09:56 <ds2> *yawn*
Feb 26 00:12:35 <veremit> ZeekHuge: there should be a few kernel options available via apt-get .. not sure what the most sensible way of listing them is, though ..
Feb 26 00:13:24 <ZeekHuge> and how can i rectify do with this dpkg error ?
Feb 26 00:18:45 <veremit> hmm no idea why you should need to do that .. sounds like something's got corrupted somewhere
Feb 26 00:20:15 <ZeekHuge> well, the process got stuck at "c9-core-installer:Installing node-gyp@2.0.2". I skipped it using "ctrl-C" and now its downloading "ti_cgt_pru_2.1.2_armlinuxa8hf_busybox_installer.sh"
Feb 26 00:21:13 <veremit> you haven't run out of emmc "disk"space? what does 'df -h' say?
Feb 26 00:22:03 <veremit> you'll really upset apt if you ctrl-c out of it
Feb 26 00:22:16 <zmatt> ZeekHuge: note that 4.1-bone still has uio_pruss afaik
Feb 26 00:24:10 <zmatt> and capemgr is in all of them, although 4.1 and later additionally has the mainline configfs mechanism to load overlays
Feb 26 00:24:18 <ZeekHuge> zmatt : yes, but I need to work on remoteproc.
Feb 26 00:24:33 <zmatt> ok, then you need 4.1-ti
Feb 26 00:25:13 <ZeekHuge> and how can i get that ?
Feb 26 00:27:08 <dwery> https://github.com/dwery/nrf24le1-bbb for those interested in the nrf24le1
Feb 26 00:27:17 <zmatt> ZeekHuge: it's default in current jessie images
Feb 26 00:27:47 <zmatt> or rather, 4.1-ti-rt is default in the latest snapshots, but you can easily apt-get install a different kernel image if you want to
Feb 26 00:32:18 <ds2> ewwwwwwwwwwwwwww capes
Feb 26 00:41:00 <veremit> <zmatt> ZeekHuge: it's default in current jessie images
Feb 26 00:41:00 <veremit> [Fri 12:27 am] <zmatt> or rather, 4.1-ti-rt is default in the latest snapshots, but you can easily apt-get install a different kernel image if you want to
Feb 26 00:47:22 <ZeekHuge> ohk so veremit, the latest jessie image would allow me to use remoteproc on it ?
Feb 26 00:47:44 <veremit> I defer to zmatt on that ....
Feb 26 00:47:49 <zmatt> should yes
Feb 26 00:48:05 <veremit> but neither of us have used the pru's yet
Feb 26 00:48:21 <alexhiam_> ZeekHuge: all those PRU things from gsoc 2015 should run on the jessie image
Feb 26 00:48:43 <ZeekHuge> Ohk :) thank you :)
Feb 26 00:57:05 <zmatt> and once I do start using it'll most likely be using uio_genirq_pdrv :P
Feb 26 01:04:12 <veremit> is that another zmatt-special?! :P
Feb 26 01:04:19 <zmatt> ?
Feb 26 01:04:42 <veremit> ah ofc .. its uio :P
Feb 26 01:05:03 <veremit> zmatt: zmatt's special library
Feb 26 01:05:35 <zmatt> it's a mainline driver enabled in all of rcn-ee's recent kernels (I think all series, all the way down to 3.8-bone), hence avoids any dependency on a particular kernel version
Feb 26 01:06:14 <veremit> oh I'm confusing it with the other thingy then
Feb 26 01:06:24 <veremit> I'll blame it on tiredness .. long day :/
Feb 26 01:07:51 <zmatt> it's a bit like /dev/mem but it restricts access to just the range(s) designated in DT for that device, lets non-root users use it (given appropriate udev rules), and allows receiving irqs in userspace
Feb 26 01:08:19 <veremit> or was it the one you did create ..
Feb 26 01:08:30 <zmatt> I did not create it, it's been mainline since ancient history
Feb 26 01:08:57 <veremit> ok scratch that .. vortex in memory ..
Feb 26 01:10:05 <zmatt> the only linux "driver" I've ever created is a dummy alsa "codec" to be able to just enable McASP without the kernel knowing anything about a codec
Feb 26 01:10:39 <zmatt> I'm no linux kernel programmer nor do I pretend to be
Feb 26 01:11:13 <veremit> hmm yeah that much I shjould know
Feb 26 01:11:18 <veremit> 2+2=5 lately though
Feb 26 01:11:56 <zmatt> that would be unfortunate, since that implies 0=1 which is only true in the https://en.wikipedia.org/wiki/Zero_ring
Feb 26 01:12:23 <veremit> oh I've mistakenly proven 0=1 many times with Indentities (maths trig functions)
Feb 26 01:12:31 <veremit> Identities*
Feb 26 01:13:01 <veremit> you always knew something had gone wrong at that point lol
Feb 26 01:13:08 <zmatt> a screwed up proof doesn't make something true ;)
Feb 26 01:13:41 <veremit> no...
Feb 26 01:14:01 <zmatt> and trigonometry sucks
Feb 26 01:26:04 <veremit> its quite useful though
Feb 26 01:26:17 <veremit> I could do that.
Feb 26 01:26:33 <zmatt> sometimes, if for some reason linear algebra doesn't get the job done
Feb 26 01:26:36 <zmatt> :P
