Aug 24 03:19:21 <mranostay> m_billybob: drink some natty for me
Aug 24 03:20:13 <tacon> bleh
Aug 24 03:41:39 <ztahenakos> on boot, what does "bad device mmc 0" mean?
Aug 24 03:49:50 <joel_> ztahenakos, if you post more details maybe you'll get a better answer
Aug 24 03:51:02 <ztahenakos> joel_: thats all I really have.. during boot, I can see that print from uboot.. then later on I get devtmpfs: error mounting -2 and a kernel panick
Aug 24 03:52:37 <mrpackethead> doh doh dh
Aug 24 03:52:41 <joel_> ztahenakos, what exactly are you trying to do?
Aug 24 03:53:03 <ztahenakos> joel_: trying to port an OS I have thats not currently on the BBB to the BBB
Aug 24 03:53:17 <joel_> udev mounts on /dev as devtmpfs
Aug 24 03:56:07 <joel_> ztahenakos, I am using you are talking about the already developed Linux Kernel, and "porting" some custom userspace ;)
Aug 24 03:56:34 <joel_> ztahenakos, most likely you don't have the DEVTMPFS config option enabled in your kernel
Aug 24 03:56:54 <ztahenakos> Im using an already existing kernel, OK I got past the devtmpfs issue by creating /dev, but I still get a kpanic
Aug 24 03:57:04 <joel_> Make sure these are set in kernel config:
Aug 24 03:57:04 <joel_> CONFIG_DEVTMPFS=y
Aug 24 03:57:05 <joel_> CONFIG_DEVTMPFS_MOUNT=y
Aug 24 03:57:27 <ztahenakos> Im using the kernel supplied from the debian wheezy image from armhf.com, so I know I have a working kernel
Aug 24 03:57:40 <joel_> working has many definitions
Aug 24 03:58:01 <ztahenakos> Well I know if I use the debian wheezy image, the system actually boots and is usable
Aug 24 03:58:02 <joel_> depending on the filesystem, the kernel may or may not "work" at all after you get past init
Aug 24 03:58:15 <ztahenakos> its ext4.. what debian wheezy uses
Aug 24 03:58:51 <ztahenakos> so.. what I see during boot now is :/bin/sh: can't open fixrtc, then the kpanic
Aug 24 03:58:53 <joel_> I meant, the userspace in general, the init daemon whatever it is, there are dependencies on the way a kernel is configured/built
Aug 24 03:59:27 <ds2> stop letting process 1 die
Aug 24 03:59:35 <ztahenakos> Im sorry :(
Aug 24 03:59:40 <joel_> exactly
Aug 24 03:59:47 <joel_> check your boot args, most like you're passing some garbage to init=
Aug 24 04:00:02 <ztahenakos> the bootargs are what the optargs variable in uEnv.txt?
Aug 24 04:00:16 <joel_> that's a part of it
Aug 24 04:00:24 <joel_> check your U-boot sources for the whole thing
Aug 24 04:00:30 <ds2> it can be anywhere
Aug 24 04:00:33 <ds2> depends on ur configuration
Aug 24 04:00:44 <ztahenakos> I dont have u-boot sources, I am using an existing u-boot image from debian wheezy
Aug 24 04:01:03 <joel_> are you're "porting" an OS? ;-) Get the bootloader sources and build it yourself
Aug 24 04:01:11 <joel_> *and
Aug 24 04:01:42 <ztahenakos> yeah.. I was sort of being naive, seeing if I could take the rootfs and slam it into the required boot components, it worked for me before
Aug 24 04:03:09 <joel_> as ds2 said, get init to a point where it doesn't throw anything nasty
Aug 24 04:03:23 <ztahenakos> Well id like to do that, I dont know why inits dying
Aug 24 04:03:29 <joel_> and focus on passing the right bootargs, and configuring your kernel build correctly so that userspace is happy
Aug 24 04:04:39 <joel_> fixrtc rings a bell as some bootarg as such , which points to the fact that you probably have messed that up
Aug 24 04:05:03 <ztahenakos> Well yeah, but I dont know what it is and so far havent been able to get rid of it
Aug 24 04:06:21 <joel_> that goes back to what I said about bootloader sources, get those and figure it out from there. configure everything correctly
Aug 24 04:06:25 <joel_> night
Aug 24 04:06:39 <mranostay> joel_: don't leave us now!
Aug 24 04:06:44 <joel_> mranostay, heh
Aug 24 04:07:12 <mranostay> #beagle after dark
Aug 24 04:07:53 <joel_> usually the kernel will spit out the bootargs after decompressing so you can look at it there
Aug 24 04:08:21 <mranostay> cat /proc/cmdline from userspace
Aug 24 04:08:30 <joel_> but he can't get to userspace, that's his problem
Aug 24 04:08:55 <mranostay> can nodejs help here?
Aug 24 04:09:14 * joel_ chokes
Aug 24 04:09:49 <ztahenakos> hmm, its still gettin fixrtc, gotta figure out where thats comming from
Aug 24 04:10:49 <joel_> iirc that's some bootarg again....
Aug 24 04:11:04 <ztahenakos> yes it is
Aug 24 04:45:45 <mranostay> woot found the RLE bug!
Aug 24 04:46:21 <mranostay> seems nobody uses the OLS or Sigrok if nobody noticed in a commit from 4 months ago
Aug 24 04:47:27 <ka6sox> b00m
Aug 24 04:48:11 <mranostay> and triggers were broke too
Aug 24 05:09:58 <mranostay> two birds one stone here.. yah!
Aug 24 05:13:17 <ds2> Russ: SDK6 doesn't do DS0 but standby works using the stock image
Aug 24 05:13:32 <ds2> surprisingly the power draw in suspend vs DS0 isn't much different
Aug 24 05:21:05 <mranostay> gah pot lofting into my window
Aug 24 05:23:12 <_av500_> not pot lobbing?
Aug 24 05:26:54 <mranostay> this is suppose to be a smoke free building
Aug 24 05:29:20 <_av500_> you americans and your regulations
Aug 24 05:29:28 <tacon> lol
Aug 24 05:32:08 <mranostay> _av500_: no usually isn't the case
Aug 24 05:32:20 <mranostay> this building has that part of the lease
Aug 24 05:33:38 <_av500_> I guess you also signed for no trash burning?
Aug 24 05:35:30 <mranostay> _av500_: i live in a high rise it is probably implied :)
Aug 24 05:35:42 * mranostay doesn't recall if candles are allowed
Aug 24 05:36:20 <_av500_> plastic ones
Aug 24 05:36:28 <_av500_> like on your christmas tree
Aug 24 05:36:40 * mranostay isn't a christmas person
Aug 24 05:38:02 <_av500_> roasting a pig over open fire is a nono too?
Aug 24 05:38:56 <mranostay> well there is a common area with a grill does that count?
Aug 24 05:39:10 <_av500_> you mean like outside?
Aug 24 05:56:39 <mranostay> _av500_: yeah it effing scarey out there
Aug 24 05:56:52 <mranostay> dammit this bug is annoying me
Aug 24 05:57:00 <mranostay> i should go be social and forget it
Aug 24 05:59:36 * _av500_ throws another garbage can on the fire and turns the pig around
Aug 24 06:01:23 <mranostay> _av500_: you live in rural Germany right?
Aug 24 06:23:29 <_av500_> yeah
Aug 24 06:25:14 <mranostay> weird
Aug 24 06:35:51 <mrpackethead> your weird
Aug 24 06:36:00 <mrpackethead> mranostay: which bits did you need for your FPGA
Aug 24 06:36:07 <mrpackethead> i have quite a few spares
Aug 24 07:06:04 <_av500_> spare parts for FPGAs?
Aug 24 07:13:00 <ka6sox> _av500_, of course...we always have spare gates laying around.
Aug 24 07:54:11 <_av500_> spare a gate, mate?
Aug 24 08:11:15 <dm8tbr> mhh a Mate drink could work now
Aug 24 08:16:40 * mranostay pours vodka at dm8tbr 
Aug 24 08:24:10 * dm8tbr adds some piripiri sauce and drinks it
Aug 24 08:28:33 * mranostay should be sleeping
Aug 24 08:40:00 <ttnghiabk> hi
Aug 24 08:40:08 <ttnghiabk> I'm newbie  here
Aug 24 08:43:27 <_av500_> ttnghiabk: ask, dont ask to ask
Aug 24 08:44:53 <cxphong> Hello , Can anyone give me the name of the hardware component use to encode/decode in gstreamer on beagle bone black? Thanks!
Aug 24 08:46:29 <cxphong> gstreamer use for live video streaming
Aug 24 08:47:55 <cxphong> I use BBB to streaming video capture from usb camera
Aug 24 08:53:28 <mranostay> trolls!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Aug 24 08:58:16 <Defiant> cxphong: BBB doesn't have hw video accel
Aug 24 08:58:42 * SpeedEvil ponders PRU accel.
Aug 24 08:58:44 <SpeedEvil> :)
Aug 24 08:59:02 <mranostay> PRU!!!!!!!!!!!!!!!!!!!!
Aug 24 09:00:08 <SpeedEvil> I suspect it's probably a silly idea.
Aug 24 09:03:06 <mranostay> SpeedEvil: the PRU is my god! :P
Aug 24 09:07:16 <cxphong> PRU! ok thanks all!
Aug 24 09:10:20 <mrpackethead> lol.
Aug 24 09:10:39 <mrpackethead> can you install opencv on the PRU?
Aug 24 09:12:16 <mranostay> with god there is no limits

Aug 24 10:15:07 <woglinde> thats an absoluting fail
Aug 24 10:15:16 <woglinde> by transcend
Aug 24 10:15:36 <woglinde> and maybe case for gpl-violations.org
Aug 24 10:20:19 <woglinde> lol checking forms on the client
Aug 24 10:30:25 <woglinde> ah okay source is available

Aug 24 11:33:22 <ds_> LTSP on BBB. any ideas ?
Aug 24 11:41:35 <ds_>  LTSP on BBB. any ideas ?
Aug 24 11:42:32 <derRichard> ds_: ... what about asking a real question?
Aug 24 11:43:29 <ds_> you mean ? :)
Aug 24 11:43:37 <woglinde> any idea?
Aug 24 11:43:42 <woglinde> many solutions
Aug 24 11:44:08 <ds_> plz list out...
Aug 24 11:44:45 <derRichard> ds_: what exactly is the problem you're trying to solve?
Aug 24 11:45:16 <ds_> i wish to make a zero client using the BBB...
Aug 24 11:45:42 <ds_> PCoIP
Aug 24 11:45:53 <derRichard> then install whatever client you need on it :)
Aug 24 11:46:44 <ds_> will it be fast enough ?
Aug 24 11:47:14 <derRichard> ds_: try it...
Aug 24 11:47:37 <ds_> I want to use it on a 120x1280 res LCD
Aug 24 11:48:52 <ds_> Taking a powerful server, i want to replace 5-10 destops with the BBB...
Aug 24 11:49:54 <_av500_> sure
Aug 24 11:50:10 <ds_> but im not ubnderstanding where to start
Aug 24 11:50:19 <ds_> *understanding
Aug 24 11:50:54 <woglinde> hm av500 dejavu
Aug 24 11:50:59 <woglinde> he asked some days ago
Aug 24 11:51:04 <ds_> yup...
Aug 24 11:51:14 <derRichard> btw: currently there are not sgx-pvr drivers available
Aug 24 11:51:20 <woglinde> so he will get the same answers
Aug 24 11:51:21 <derRichard> so no fast graphics for you
Aug 24 11:51:33 <ds_> ok...
Aug 24 11:52:09 <woglinde> derRichard tomorrow he will ask the same questions
Aug 24 11:52:23 <ds_> this was the last of my effort...
Aug 24 11:52:44 <ds_> I wanted to re-think about this
Aug 24 11:53:21 <derRichard> woglinde: okay. did not know that
Aug 24 11:57:44 * derRichard can't await the bbb gpu drivers
Aug 24 12:20:01 <woglinde> derRichard hm there was some runmor nobody is working on it
Aug 24 12:20:08 <woglinde> rumor even
Aug 24 12:20:22 <derRichard> hm, very sad.
Aug 24 12:21:18 <derRichard> currently you are even unable to watch a simple video :(
Aug 24 12:35:42 <woglinde> buy a rpi for video
Aug 24 12:41:41 <derRichard> i have already a pi
Aug 24 13:00:24 <anujdeshpande> does anybody know what happened to python-opencv package in angstrom ?
Aug 24 13:15:53 <anujdeshpande> ping pdp7
Aug 24 13:16:54 <Tenkawa> pdp7: no response from host.
Aug 24 13:16:57 * Tenkawa laughs
Aug 24 13:17:03 <Tenkawa> :)
Aug 24 13:17:19 <Tenkawa> sorry
Aug 24 13:17:30 <Tenkawa> I'm a bit sarcastic
Aug 24 13:19:05 <anujdeshpande> hehe
Aug 24 13:19:26 <Tenkawa> anujdeshpande: I miss pdp11's though
Aug 24 13:19:33 <Tenkawa> and tandem
Aug 24 13:20:55 <anujdeshpande> i don't know what i missed really.. should've been born earlier :)
Aug 24 13:21:23 <Tenkawa> heheh
Aug 24 13:21:30 * Tenkawa is ancint
Aug 24 13:21:32 <Tenkawa> er anciet
Aug 24 13:21:34 <Tenkawa> fdahsmgh
Aug 24 13:21:36 <Tenkawa> ancient
Aug 24 13:21:44 <Tenkawa> wow my typing is great this morning...not
Aug 24 13:22:07 * anujdeshpande wonders where python-opencv is ..
Aug 24 13:22:45 <Tenkawa> which distro?
Aug 24 13:22:56 <derRichard> angstrom
Aug 24 13:23:12 <anujdeshpande> yepp
Aug 24 13:23:14 <Tenkawa> no idea.. I only run debian/slackware based stuff on my bbb
Aug 24 13:23:25 <anujdeshpande> its listed here http://www.angstrom-distribution.org/feeds/next/ipk/eglibc/armv7a/python/Packages
Aug 24 13:23:40 <anujdeshpande> but can't get it
Aug 24 13:25:43 <Tenkawa> what error you get?
Aug 24 13:26:26 <anujdeshpande> Unknown package 'python-opencv'
Aug 24 13:27:19 <Tenkawa> ahhh
Aug 24 13:27:32 <Tenkawa> what utility does angstrom use to get packages?
Aug 24 13:27:48 <Tenkawa> you might have to use a different search/packagename
Aug 24 13:28:54 <Tenkawa> you've run opkg update right?
Aug 24 13:30:05 <anujdeshpande> opkg
Aug 24 13:30:05 <anujdeshpande> yupp
Aug 24 13:30:10 <Tenkawa> intriguing
Aug 24 13:30:42 <Tenkawa> ahhh
Aug 24 13:30:47 <Tenkawa> try just opencv
Aug 24 13:49:42 <anujdeshpande> opencv comes installed by default
Aug 24 13:55:53 <Tenkawa> well darn
Aug 24 14:17:19 <woglinde> anujdeshpande koen had some trouble whie building it so he disabled it in his last builds
Aug 24 14:17:53 <Tenkawa> woglinde: ahhh... good reason
Aug 24 14:21:08 <anujdeshpande> woglinde: i see . i was hoping to give a demo for that on a workshop tomorrow.
Aug 24 14:21:22 <anujdeshpande> *at a workshop
Aug 24 14:21:37 <woglinde> anujdeshpande hm you could try to compile it yourself
Aug 24 14:22:25 <anujdeshpande> could give it a shot.. but have some other demos to work on too..
Aug 24 14:22:32 <woglinde> 2.2 is old anyway and if I remember right it was 2.4 where they switched to numpy for storing images
Aug 24 14:23:42 <anujdeshpande> woglinde: i think we have 2.4.2 on angstrom
Aug 24 14:24:26 <woglinde> yes but without python
Aug 24 14:25:12 <alphacentauri> Date.getFullYear() doesn't work in cloud9 ide--missing method?  solution, please?
Aug 24 14:25:21 <woglinde> what you found has python-opencv 2.2.0+svnr4812-r3.9
Aug 24 14:25:32 <anujdeshpande> indeed.
Aug 24 14:25:47 <anujdeshpande> so if i have to compile it, i'll have to do 2.2
Aug 24 14:25:53 <anujdeshpande> that's a shame ..
Aug 24 14:26:15 <woglinde> hm?
Aug 24 14:26:16 <woglinde> why
Aug 24 14:26:19 <anujdeshpande> i guess i'll call a c++ executable to get images and then run a python script
Aug 24 14:26:27 <woglinde> try to compile latest 2.4.6.2
Aug 24 14:26:32 <woglinde> ups 2.4.6.1
Aug 24 14:27:00 <woglinde> alphacentauri few working with the javascrpt foo
Aug 24 14:27:08 <woglinde> ask jkridner
Aug 24 14:27:55 <anujdeshpande> woglinde: you know if this has been fixed in the image release yday ?
Aug 24 14:28:01 <anujdeshpande> *released
Aug 24 14:29:14 <woglinde> do not think so
Aug 24 14:29:29 <anujdeshpande> hmm.. thanks
Aug 24 14:29:36 <alphacentauri> woglinde, got BBB few days ago and already pulling my hair :p   i'm trying to set eclipse cdt up...
Aug 24 14:30:13 <anujdeshpande> alphacentauri: it was pretty straight forward for me.
Aug 24 14:30:31 <anujdeshpande> i have eclipse+cdt+angtrom cross compilation on my machine
Aug 24 14:31:29 <alphacentauri> my pc is windows, not linux so i'm trying to set up
Aug 24 14:31:44 <woglinde> hm okay latest recipe in meta-openemebdded has it enabled again
Aug 24 14:31:58 <woglinde> I meant opencv-python
Aug 24 14:32:14 <woglinde> so you could try to build your own image
Aug 24 14:33:18 <anujdeshpande> alphacentauri: ahh ..
Aug 24 14:33:43 <anujdeshpande> woglinde: thanks. will do
Aug 24 14:35:06 <woglinde> alphacentauri I wonder why you need arm cross compiler for javascript
Aug 24 14:37:53 <alphacentauri> woglinde: cross compiler for c/c++, not javascript
Aug 24 14:38:28 <woglinde> sure but what language Date.getFullYear() comes from?
Aug 24 14:38:34 <woglinde> you did not tell us
Aug 24 14:39:04 <alphacentauri> woglinde: date.getfullyear() -> javascript
Aug 24 14:39:54 <woglinde> ah
Aug 24 14:40:02 <woglinde> now you see your conflict
Aug 24 14:41:31 <alphacentauri> but Date.getFullYear() doesn't work in cloud9 and i wonder why...
Aug 24 14:42:37 <woglinde> hi emeb
Aug 24 14:43:35 <alphacentauri> Date.getYear() doesn't work too, strange
Aug 24 14:43:59 <derRichard> alphacentauri: var d = new Date(); d.getYear(); does not work?
Aug 24 14:44:03 <derRichard> please define "does not work"
Aug 24 14:44:08 <derRichard> do you get an error?
Aug 24 14:45:23 <alphacentauri> hmm...i have to make an instance of Date?  how to get the system date?
Aug 24 14:45:38 <alphacentauri> bbb's system date/time, i mean
Aug 24 14:45:58 <derRichard> please read javascript docs
Aug 24 14:46:48 <derRichard> IIRC cloud9 is just a node.js thingy.
Aug 24 14:47:06 <alphacentauri> var year = Date.getYear() won't work, right?
Aug 24 14:47:47 <derRichard> again, please read js docs
Aug 24 17:17:53 <woglinde> gm prpplague
Aug 24 17:18:12 <prpplague> greetings
Aug 24 17:18:34 <NOUK> Hi guys anyone experiences with hooking up Beagle Bone BLACK INputting DMX?
Aug 24 17:18:58 <NOUK> Aswell Xbee + Beagle Bone Black - I could only found normal Beagle Bone + Xbee
Aug 24 17:20:26 <woglinde> what is DMX?
Aug 24 17:20:42 <maxinux> light control protocol
Aug 24 17:20:44 <maxinux> dmx512
Aug 24 17:21:20 <NOUK> Serial communication is mainly the thing
Aug 24 17:21:32 <NOUK> Setup / configuration question
Aug 24 17:22:23 <woglinde> ?
Aug 24 17:26:36 <SpeedEvil> dmX is a multi-drop serial (not rs232) bus for light controls.
Aug 24 17:26:51 <SpeedEvil> so you can make lights flash at the right time in a performance
Aug 24 17:27:32 <NOUK> yes
Aug 24 17:27:34 <NOUK> correct
Aug 24 17:27:38 <NOUK> anybody experience
Aug 24 17:31:35 <NOUK> How to make a serial port open so it can connect with any wireless device, thsi would already be enough
Aug 24 17:31:39 <NOUK> The DMX part I would know
Aug 24 17:37:08 <woglinde> NOUK o.O first you must wire it
Aug 24 17:39:04 <mranostay> morning
Aug 24 17:39:16 <woglinde> moooning mranostay
Aug 24 17:40:53 <NOUK> huhu
Aug 24 17:47:21 <mranostay> blech foggy day
Aug 24 17:48:13 <ka6sox> and you live where?
Aug 24 17:53:12 <woglinde> gm ka6sox
Aug 24 17:56:08 <mranostay> yes i know :)
Aug 24 17:59:25 <ka6sox> morning woglinde
Aug 24 18:01:50 <_SY_> hello
Aug 24 18:02:11 <_SY_> having fun with node, pretty funcky :)
Aug 24 18:03:27 <NOUK> This is what I found now
Aug 24 18:03:28 <NOUK> http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/
Aug 24 18:03:50 <NOUK> But it sounds much more complicated than when we would try to archieve the same but on an notrmal beagle bone
Aug 24 18:03:53 <rien_> I understand "never ask to ask" but I just wanted to see if anyone is running Armpit here that would have some tips for my getting started
Aug 24 18:04:20 <woglinde> what is armpit?
Aug 24 18:04:30 <_SY_> I've done this for a couple of UARTS on my two BBB's, enabling UART4 and UART5...I'll just get evernote up and then post how.
Aug 24 18:04:38 <rien_> armpit scheme
Aug 24 18:04:53 <rien_> woglinde: a scheme that runs right on ARM without an OS or anything
Aug 24 18:05:24 <NOUK> Also - experience with connecting Xbee without Xbee adapters to Beagle Bone Black
Aug 24 18:05:41 <_SY_> To enable UART4:
Aug 24 18:05:42 <_SY_> echo BB-UART4 > /sys/devices/bone_capemgr*/slots
Aug 24 18:05:51 <NOUK> Thank you _SY_!
Aug 24 18:06:03 <_SY_> To enable at boot, add to uEnv.txt in /media/BEAGLEBONE/
Aug 24 18:06:03 <_SY_> mount /dev/mmcblk0p1 /media/BEAGLEBONE
Aug 24 18:06:41 <woglinde> rien_ I dont know anybody here doing this
Aug 24 18:06:46 <_SY_> vi uEnv.txt
Aug 24 18:06:46 <_SY_> optargs=quiet drm.debug=7 capemgr.enable_partno=BB-UART4,BB-UART5
Aug 24 18:07:09 <woglinde> _SY_ fist he has to connect his xbee to the right pins
Aug 24 18:07:20 <rien_> woglinde: ok, thanks, that's what I wanted to know.
Aug 24 18:07:20 <woglinde> first even
Aug 24 18:07:32 <_SY_> UART4 Pins:
Aug 24 18:07:32 <_SY_> CTSN P8-35
Aug 24 18:07:32 <_SY_> RTSN P8-33
Aug 24 18:07:32 <_SY_> RXD  P9-11
Aug 24 18:07:33 <_SY_> TXD  P9-13
Aug 24 18:07:33 <_SY_> GND  P8-1
Aug 24 18:07:33 <_SY_> UART5 Pins:
Aug 24 18:07:34 <_SY_> RXD  P8-38
Aug 24 18:07:34 <_SY_> TXD  P8-37
Aug 24 18:07:40 <woglinde> ieeehlks
Aug 24 18:07:45 <woglinde> pastebin please
Aug 24 18:07:59 <woglinde> btw. it  is on the hipsterpage too
Aug 24 18:08:26 <woglinde> _SY_ but so far he did not tell us if he already has done the connecting
Aug 24 18:09:24 <_SY_> ok, np, I'll shut up :)
Aug 24 18:09:37 <woglinde> _SY_ hm btw. cannt you connect the stuff to what ever pins youn want and than setup the dto file right?
Aug 24 18:09:41 <NOUK> SY - can I email u
Aug 24 18:09:47 <woglinde> lol
Aug 24 18:10:30 <_SY_> No the pin functions are dedicated, if you don't have it already download the beaglebone PDF, all the PIN functions are detailed there.
Aug 24 18:10:46 <woglinde> hm yes saw it now
Aug 24 18:11:02 <woglinde> so two extra serial consoles
Aug 24 18:13:01 <_SY_> I have written a small C libary to communicate with the ports and provide JNI routines so I can call it from Java.
Aug 24 18:18:10 <_SY_> email received and response sent
Aug 24 18:18:42 <woglinde> _SY_ hm rxtx lib was to complicated?
Aug 24 18:19:23 <woglinde> _SY_ are you using angstroem?
Aug 24 18:19:32 <_SY_> I couldn't get it to work properly so after a few frustrating hours I decided to write my own, yes I'm using Angstrom
Aug 24 18:19:39 <woglinde> good
Aug 24 18:19:51 <woglinde> so you are using the java stuff from me
Aug 24 18:20:17 <_SY_> what would that be ?
Aug 24 18:20:42 <woglinde> or are using the oracle 8 pre arm kit?
Aug 24 18:20:53 <_SY_> For setting up Java I found these links helpful, I'm using the openjdk
Aug 24 18:21:01 <_SY_> Download Java from
Aug 24 18:21:01 <_SY_> http://bradsmc.blogspot.co.uk/2013/05/installing-openjdk-6-on-beaglebone-black.html
Aug 24 18:21:01 <_SY_> Java remote debugging:
Aug 24 18:21:01 <_SY_> http://www.ibm.com/developerworks/library/os-eclipse-javadebug/
Aug 24 18:21:13 <woglinde> good I am the maintainer of meta-java
Aug 24 18:21:24 <_SY_> cool
Aug 24 18:21:46 <_SY_> I've written a couple of apps using the openjdk for the BBB....both I'm quite proud of.
Aug 24 18:22:37 <_SY_> The first is a floating IP address manager, which enables me to cluster two BBB, the floating IP address app allows a client to talk to either BBB using one IP address, if I power down the active BBB, the IP moves to the other.
Aug 24 18:23:08 <_SY_> The other application I wrote is an industrial PLC modbus slave application, that allows any Modbus TCP master to read I/O from the BBB.
Aug 24 18:23:13 <woglinde> hm looks like I have to RDEPENDS giflib abd libffi
Aug 24 18:24:02 <_SY_> For remote debugging java I wrote a script containing:
Aug 24 18:24:03 <_SY_> jdbg script:
Aug 24 18:24:03 <_SY_> java -Xdebug -Xrunjdwp:transport=dt_socket,address=192.168.1.160:1044,suspend=y -jar mmsqlsvr.jar
Aug 24 18:24:22 <woglinde> yes I know
Aug 24 18:24:38 <_SY_> the IP address is my own BBB IP and the jar file at the end is my Modbus slave sql server application.
Aug 24 18:25:02 <woglinde> are using 6 or 7`
Aug 24 18:25:29 <_SY_> can't remember, hold on will power up BBB and check
Aug 24 18:26:56 <woglinde> okay I will be back in some minutes
Aug 24 18:28:32 <_SY_> java version "1.6.0_24"
Aug 24 18:28:33 <_SY_> OpenJDK Runtime Environment (IcedTea6 1.12pre) (6b24-1.11.1+1.11.2-devel+hg1+54ceda20a02c)
Aug 24 18:28:33 <_SY_> OpenJDK Zero VM (build 20.0-b12, mixed mode)
Aug 24 18:49:32 <woglinde> _SY_ hm this older and has some security flaws
Aug 24 18:50:06 <_SY_> ok, my BBB aren't online so I'm not to worried
Aug 24 18:50:22 <woglinde> gm mrpackethead
Aug 24 18:51:20 <woglinde> but good to see my work is still usefull for some
Aug 24 18:51:30 <woglinde> most switching to the oracle arm
Aug 24 18:51:47 <_SY_> Works fine :)
Aug 24 18:52:40 <_SY_> I'm not a big fan of Oracle...since Oracle has purchased various open source projects, such as mySQL they are actively trying to find out whose using it and trying to find some ways of charging for it.
Aug 24 18:58:31 <mrpackethead> And oracle are cheats
Aug 24 18:58:54 <mrpackethead> Team NZ will hopefully will whip them though on the race track
Aug 24 19:01:12 <norbi> hi guys, i followed this example for pwm http://forum.beaglefu.com/topic/59-quick-beaglebone-black-pwm-commands/
Aug 24 19:01:26 <norbi> but i cant see anything like pwm on the pin 13 on P8
Aug 24 19:01:32 <norbi> why is that?
Aug 24 19:01:41 <norbi> it need reboot
Aug 24 19:01:42 <norbi> ?
Aug 24 19:02:35 <_SY_> Do you have an oscilloscope?
Aug 24 19:03:26 <mrpackethead> did you set the pin mux ccorrectly
Aug 24 19:06:55 <norbi> yes i have an osciloscope, a RIGOL ds1102e
Aug 24 19:07:00 <norbi> now ive found the problem
Aug 24 19:07:28 <norbi> my pwm_test_p8_12.#  wasnt 15 but it was 14
Aug 24 19:12:47 * mranostay stabs the advanced pointers
Aug 24 19:16:42 <KJH_> Hi. I'd like to create an encrypted partition image on a beaglebone black, using the OS installation it came with. It has dmsetup, but no device mapper in the kernel. Or so it seems.
Aug 24 19:17:27 <KJH_> That seems strange - to have dmsetup and no device mapping in the kernel. Or a kernel module that you can load.
Aug 24 19:17:52 <KJH_> That is to say - dmsetup is relatively useless executable that way.
Aug 24 19:18:45 <rien_> Hey folks. I know 0 about electronics. What should I read to be able to understand what I'm doing when I start playing with the beagleboard? I plan on running scheme on it. Is there some material that is usually recommended for beginners (in electronics, not programming)?
Aug 24 19:19:51 <_SY_> Try the Dummies guide to electronics, its a pretty good book, goes through the basics
Aug 24 19:20:00 <mrpackethead> oh, your professors where from the Lisp camp huhm
Aug 24 19:20:11 <woglinde> mrpackethead who?
Aug 24 19:20:34 <mrpackethead> woglinde rien_:
Aug 24 19:20:49 <rien_> _SY_: ok! yes those dummy books are either very very good or very poor. will check it out
Aug 24 19:21:06 <_SY_> Got mine on Amazon
Aug 24 19:21:14 <rien_> mrpackethead: yes indeed, I want to get to the point of running a webserver on scheme without an OS
Aug 24 19:21:39 <mrpackethead> how are yu going to implement scheme without an OS
Aug 24 19:21:41 <mrpackethead> ?
Aug 24 19:21:50 <mrpackethead> that is a serious hunk of effort
Aug 24 19:21:53 <rien_> _SY_: by Lowe or McComb?
Aug 24 19:22:22 <_SY_> Gordown McComb
Aug 24 19:22:26 <_SY_> *Gordon
Aug 24 19:22:37 <rien_> mrpackethead: I won't, it's already done, it's called Armpit, and it runs on the Beagleboard, I just have no clue how to actually get started (things like, you know, transferring the payload onto the board and starting it up and so on)
Aug 24 19:22:54 <rien_> _SY_: thanks again
Aug 24 19:23:05 <_SY_> np :)
Aug 24 19:25:00 <rien_> mrpackethead: I want to understand e.g. why is the LED accessed the way it is... then understand ports, I think. I barely know the terminology but I have a vague idea of the knowledge I lack
Aug 24 19:25:12 <mrpackethead> rien_: have you got a link to the "bare metal" installation of scheme
Aug 24 19:25:19 <rien_> mrpackethead: yes give me a sec
Aug 24 19:26:05 <rien_> mrpackethead: here you are (incidentally, that's what I'd like to understand - the low level operations it's doing (I already know scheme :) ) -> http://armpit.sourceforge.net/v0171/armpit_0171_TI_Beagle_examples.html
Aug 24 19:27:14 <rien_> it's interesting that it isn't more well known given that running scheme on bare metal is many a lisper's wet dream (myself included)
Aug 24 19:27:21 <mrpackethead> rien_: armpit has an OS
Aug 24 19:28:08 <mrpackethead> minimal
Aug 24 19:28:15 <mrpackethead> but still has a kernel
Aug 24 19:28:26 <rien_> mrpackethead: you mean the runtime? that's not really an OS, it's an expected part of any lisp.
Aug 24 19:28:40 <rien_> and it's turtles all the way down, which is what matters
Aug 24 19:29:43 <mrpackethead> well, good luck to you
Aug 24 19:29:56 <mranostay> hmmm finding a pointer alias.. fun fun
Aug 24 19:32:25 <rien_> mrpackethead: do you use the beagleboard for software or hardware endeavors?
Aug 24 19:32:39 <rien_> mrpackethead: I'm curious because you seemed interested in checking out the scheme link :)
Aug 24 19:32:46 <mrpackethead> dont' use the beagleboard
Aug 24 19:32:49 <mrpackethead> use beaglebones
Aug 24 19:33:22 <mrpackethead> but you have to use them for both heardare and software
Aug 24 19:35:42 <rien_> mrpackethead: I don't plan on running anything atop Linux. or do you mean use the beaglebones and chuck linux?
Aug 24 19:36:09 <mrpackethead> i use beagleboneblack and debian
Aug 24 19:37:30 <rien_> mrpackethead: hmm, maybe if I can install scheme atop that linux then that might be enough to kickstart this journey; you're right.
Aug 24 19:38:21 <rien_> obviously it comes with gcc and other dev tools?
Aug 24 19:38:48 <rien_> I love debian, that's what I use for my servers, so... interesting :)
Aug 24 19:41:57 <rien_> there's no beagleboard that comes with wifi already working and configured on its linux?
Aug 24 19:42:05 <rien_> I understand there are dongles etc
Aug 24 19:45:20 <mranostay> koen: ok this C stuff is too hard i'm going to do nodejs here on out :P
Aug 24 19:45:22 <woglinde> o.O
Aug 24 19:45:45 <rien_> hahah
Aug 24 19:45:46 <Spirilis> lawl
Aug 24 19:46:14 <rien_> re the beaglebone black, says it's 1 GHz, how much is that in x86 terms?
Aug 24 19:46:32 <mranostay> woglinde: i see the err of my ways :P
Aug 24 19:46:51 <norbi> is a 620ohm 0.2W resistor consuming too much power on the BBB output pin?
Aug 24 19:46:56 <woglinde> mranostay I do not know what you are working on
Aug 24 19:47:20 <norbi> i have a 0.2W resistor on the pwm pin and is that a problem ?
Aug 24 19:47:54 <rien_> it also doesn't say how many mips
Aug 24 19:50:01 <SpeedEvil> 5 volts / 620 ohms = about 8mA
Aug 24 19:50:11 <SpeedEvil> 8ma*5V = 40mw - .04W
Aug 24 19:50:56 <norbi> SpeedEvil: 3.3V on the beagleboard
Aug 24 19:51:10 <SpeedEvil> err, yes
Aug 24 19:51:13 <SpeedEvil> so 20mw ish
Aug 24 19:52:05 <norbi> SpeedEvil: so this resistor is too big?
Aug 24 19:52:16 <SpeedEvil> what are you trying to do with it
Aug 24 19:52:37 <norbi> protecting the board from too high drain
Aug 24 19:52:49 <norbi> but the resistor itself produces a drain
Aug 24 19:53:04 <_av500_> ?
Aug 24 19:53:10 <_av500_> put it in series
Aug 24 19:53:12 <norbi> SpeedEvil: or im not calculating it right
Aug 24 19:53:29 <SpeedEvil> 'too high a drain' ?
Aug 24 19:53:44 <norbi> 250mW is the max drain on it? and the resistor doesnt have too much by itself?
Aug 24 19:54:12 <SpeedEvil> you are not making significant amounts of sense.
Aug 24 19:54:19 <SpeedEvil> What do you hope the resistor will do.
Aug 24 19:54:29 <norbi> SpeedEvil: i mean BBB can give max 6mA on a GPIO and a led consumes 20mA and thats already high, im trying to protect the pin and limit the current to 6mA
Aug 24 19:54:49 <_av500_> so calculate what you need
Aug 24 19:55:00 <_av500_> 3.3v - V_led / 6mA
Aug 24 19:55:09 <_av500_> +(   )
Aug 24 19:55:25 <_av500_> and I think it was 4mA, no?
Aug 24 19:56:56 <norbi> 6
Aug 24 19:57:57 <_av500_> ok
Aug 24 19:59:29 <norbi> so the mcu pin will be not dmged by the resistors load, right?
Aug 24 20:00:03 <_av500_> depends
Aug 24 20:00:08 <_av500_> on how you load it
Aug 24 20:00:27 <_av500_> 3.3V/6mA = 550 Ohm
Aug 24 20:00:29 <_av500_> no?
Aug 24 20:00:36 <_SY_> nite all,
Aug 24 20:00:41 <_av500_> 620 should be fine
Aug 24 20:00:44 <_av500_> in all cases
Aug 24 20:01:11 <_av500_> still: (3.3V - V_led) / 6mA to be exact
Aug 24 20:02:24 <norbi> _av500_: i was more affraid from the disipated current because i want to protect the board as much as possible
Aug 24 20:07:25 <_av500_> ?
Aug 24 20:07:35 <_av500_> what current?
Aug 24 20:48:49 <mrpackethead> eww, the Kiwis just thumped the itlains
Aug 24 21:55:27 * mranostay goes out to bike
Aug 24 22:56:41 <JViz> does anyone happen to have the pcblib from the Altium design files for the bbone black?
Aug 24 23:04:32 <mranostay> JViz: eh?
Aug 24 23:04:46 <mranostay> sure you have the right version?
Aug 24 23:05:15 <JViz> no, it's the one off the circuitco wiki
Aug 24 23:06:02 <JViz> it's the best version i've been able to find so far though
Aug 24 23:07:53 <mranostay> i mean of Altium
Aug 24 23:07:59 <JViz> oh
Aug 24 23:08:27 <Thefatpinkpig> hello
Aug 24 23:09:19 <Thefatpinkpig> will the beaglebone black work with an HDMI to VGA?
Aug 24 23:10:26 <JViz> mranostay, version 13.2.5
Aug 24 23:11:19 <JViz> lol
Aug 24 23:11:21 <JViz> he left
Aug 24 23:11:33 <JViz> i don't think the beagle has a ramdac, so no
Aug 24 23:22:00 <JViz> mranostay, are you still there?
Aug 24 23:37:42 <mranostay> JViz: yeah kinda
Aug 24 23:38:24 <JViz> :)
Aug 25 02:06:05 <Alviur> Hi can you give some link about how to use the DSP micro from beagleboard c3
