**** BEGIN LOGGING AT Fri Aug 03 02:59:59 2012 Aug 03 04:36:12 mikeg jsabeaudry I used the config from mikeg's patch which almost applied cleanly and rt_preempt-3.2.23-rt37 patch on the latest meta-ti (3.2.23) and it built and booted no prob, I logged in over ethernet but haven't done anything else. THANKS! Aug 03 04:36:20 Linux omap 3.2.23-rt37 #1 PREEMPT RT Thu Aug 2 21:19:02 PDT 2012 armv7l armv7l armv7l GNU/Linux Aug 03 04:39:37 last time I tried rt_preempt patch I used rcn's script and it wouldn't boot, but that was a few months ago Aug 03 04:43:28 3.2.23-r14h... Aug 03 05:27:21 <_av500_> guys, the #rpi channel is ruined now Aug 03 05:29:34 _av500_: you took over? Aug 03 05:38:54 <_av500_> no Aug 03 05:39:06 <_av500_> all the beagle troll are lining up there Aug 03 05:39:08 <_av500_> trolls Aug 03 05:39:21 <_av500_> poor kids wont get a decent compter learning now.... Aug 03 05:40:09 teehee Aug 03 05:40:42 explains the silence Aug 03 05:40:47 <_av500_> when I joined I get almost kicked out for asking why it cannot decode mpeg2 Aug 03 05:40:52 <_av500_> got* Aug 03 05:40:58 <_av500_> since the hw supports it Aug 03 05:42:13 :) Aug 03 05:43:03 <_av500_> the answer is they do not license the mpeg2 part Aug 03 05:43:41 <_av500_> i wonder why ti can offer the mpeg2 decoder blob and bcm cant Aug 03 05:43:53 <_av500_> oh wait, is mpeg2 in the mix? Aug 03 05:45:57 <_av500_> but then I dont think ti covers any license fees - and they do offer h264 and mpeg4 Aug 03 05:57:41 why is it raspi + arduino...nobody knows how to "bitbang" the raspi? Aug 03 05:59:00 <_av500_> dont they use bitbang to talk to the arduino? Aug 03 05:59:13 <_av500_> which then bitbangs whatever is connected... Aug 03 05:59:18 <_av500_> bangception Aug 03 05:59:31 sigh... Aug 03 06:00:00 all that power and its back to stone knives and bear skins. Aug 03 06:07:41 stone knives are collector items! Aug 03 06:13:58 and fur is still DEAD Aug 03 06:14:38 I really don't want to drive 300miles tommorrow. Aug 03 06:14:50 why can't the beagle drive my car for me? Aug 03 06:15:37 where are you going, ka6sox? Aug 03 06:16:00 SW San Jose, Sunnyvale Aug 03 06:16:09 SE San Jose that is. Aug 03 06:16:17 sounds fun Aug 03 06:16:20 :D Aug 03 06:16:27 you can smell the ripe garlic Aug 03 06:16:47 Mt. Hamilton Aug 03 06:17:03 that's more like E SJC or NE SJC Aug 03 06:17:06 I'll smell the garlic too early tommorrow. Aug 03 06:17:16 okay EAST SJC. Aug 03 06:17:28 but Mt Hamilton road is fun to drive Aug 03 06:17:31 aborn road. Aug 03 06:17:45 ya it is Aug 03 06:17:49 av500: serial is bitbanged in rpi Aug 03 06:17:54 you are doing that route? not alum rock? Aug 03 06:18:15 alum rock to aborn Aug 03 06:18:27 eh? they don't cross Aug 03 06:19:28 * ka6sox looks at his GPS. Aug 03 06:20:03 some parkway to aborn Aug 03 06:20:27 aborn is further south, you wind up the mtn to connect to mt hamilton rd Aug 03 06:20:48 I have to stop 1/2 way up and work on something..then going to Lick Aug 03 06:21:07 are you getting to climb towers? Aug 03 06:21:20 no, I'll let the WISP do that... Aug 03 06:21:54 adding another stream though..HD3 Aug 03 06:23:02 basic stuff Aug 03 06:23:53 ya, just reconfigure the mux, add the new encoder. Aug 03 06:24:01 (after the WISP gets done) Aug 03 06:24:40 leave the xM behind... Aug 03 06:29:32 <_av500_> koen: http://cdn.memegenerator.net/instances/400x/24371862.jpg Aug 03 06:36:19 I already have that a -1000 on g+ Aug 03 06:37:01 <_av500_> pah Aug 03 06:37:08 <_av500_> there is only +1 Aug 03 06:37:12 <_av500_> :) Aug 03 06:37:30 <_av500_> you have to +1 100 of my posts and then revoke them all at the same time Aug 03 06:37:41 <_av500_> 1000* Aug 03 06:39:03 * _av500_ has reached the time of day when 2g is faster than mesh wifi Aug 03 06:58:20 <_av500_> koen: raspcapes: http://www.cnx-software.com/2012/08/03/raspicomm-raspberry-pi-expansion-board Aug 03 10:10:22 Can I get some assistance with pin muxing? Aug 03 12:32:35 "this patch series implements Xen support for ARMv7 with virtualization" - can I run rpi on beagle? Aug 03 12:40:04 ynezz: its not easy to run virtualized arm systems because arm is patented and thus virtual machine thats free and open wont be touching most arm Aug 03 12:40:05 enjoy Aug 03 12:40:36 what that says that you pasted is that they got Xen hosting working on armv7 hosts i assume Aug 03 12:41:48 luckily for arm though, armv4 compiled stuff should run on armv7 for example like how 386 runs on 686 and so forth Aug 03 12:42:04 well luckily for open source projects ^ Aug 03 12:43:11 ynezz: no, it would run to fast Aug 03 12:43:21 ynezz: screws up all the timings for bitbanging the ports Aug 03 12:44:16 wtf? Aug 03 12:44:25 omap5-evm has a barometric pressure sensor?!?!?! Aug 03 12:44:44 for those robot makers of course Aug 03 12:45:48 well sure its usefull for homes too Aug 03 12:45:50 -.- Aug 03 12:45:54 * ccssnet shuts up Aug 03 13:21:47 koen: you don't have that omap5-evm board under your pillow yet? Aug 03 13:22:08 that fishbone... Aug 03 13:28:40 koen, you said bitbanging Aug 03 14:20:28 What happened at the time of the great bit bang? Aug 03 14:22:27 koen: they stole the idea from the snowball!!!one!eleven! Aug 03 14:56:31 I'm logged in to my beagleboard via the serial connection, screen running on my laptop. I can't seem to kill a running app using "ctrl-c", is there something i'm missing ? Aug 03 14:57:27 Maybe there is something I have to enable in the kernel/uClibc/busybox ? Aug 03 15:03:05 no job control on the terminal Aug 03 15:03:11 iirc it's not enabled by default on serial terminals Aug 03 15:04:29 aha.. I have a busybox switch, CONFIG_ASH_JOB_CONTROL, which is not set.. Aug 03 15:04:45 and I'm using ash Aug 03 15:05:31 i'll try turning it on, but you suspect it will still not work ? Aug 03 17:38:58 I'm using a BeagleBoard xM with an image generated via Narcissus, and looking for a fix for the random MAC address. There's a lot of confusing/outdated information out there, what's the latest recommended approach? Aug 03 19:05:41 no matter what a do, "-c clean" or "rm -rf build/tmp-angstrom_v2012_05-eglibc" when I build the kernel the deploy/images/... deirectory has images/modules from last night instead of the new build Aug 03 19:06:22 anyone having any good guides on preparing a sd card for boot an xm. Aug 03 19:07:11 shawn_, i've had good luck with http://www.elinux.org/BeagleBoardUbuntu Aug 03 19:08:48 thanks, i will check it out. i spent hours looking at different one on-line. I tried one from sakoman.com. it however didn't turn out so well. the beagle board didn't boot Aug 03 19:10:48 you don't have to use his ubuntu images, there is a bunch of info on setting up uboot there, preparing a uImage, etc... Aug 03 19:13:20 well, i used buildroot to generate all the stuff i needed. now i need to get the stuff onto a card "the correct way" to see if it works Aug 03 19:28:14 burris: -c cleansstate Aug 03 19:28:28 burris: or increase PR for changes you make, as you're supposed to Aug 03 19:40:43 koen thanks! do I just add PR to the uImage bb? (linux-ti33x-psp_3.2.bb, it doesn't have PR) Aug 03 19:41:06 change the MACHINE_KERNEL_PR_append Aug 03 19:41:14 that resolves to PR in the end Aug 03 19:41:24 ok, thank you Aug 03 22:28:08 Hi, I am trying to configure a webcam with Beaglebone. I look for this in Google and many people seem to have the same problem, but I couldn't find a solution. Can anybody help me? Aug 03 22:28:50 I used the following command: Aug 03 22:28:52 gst-launch v4l2src num-buffers=1 ! ffmpegcolorspace ! video/x-raw-yuv,width=320,height=240 ! jpegenc ! filesink location=test.jpg Aug 03 22:29:30 and I got a picture from my webcam (of course, connected to the beaglebone). It is low resolution, but it seems to work. Aug 03 22:31:38 But I am a simple OpenCV ptogram doesn't work Aug 03 22:44:33 I just build a console-image of Angstrom v2012.05 with kernel 3.2.18 and I'm also getting the "Cannot make/remove an entry for the specified session" error when logging in as root as the console. This isn't happening with prebuilt demo binaries. Aug 03 23:15:24 Hi folks. New here. I have just bought a BeagleBone and am looking for some advice on using my BB to trigger the button on my intercom to release my security door. I know need a relay to do the switching but im sure there are other components required. Can anyone offer some advice to an eager to learn noob.? Aug 03 23:16:49 do you have linux driver experience? Aug 03 23:17:57 @mikejones: me? I do not. Aug 03 23:20:46 defecta: yea you, ok, well the BB has a bunch of things exposed with the sysfs interface Aug 03 23:20:51 To be more specific, it's advice about what hardware/electronic components I need rather than the software code side. That I can experiment with till it works without breaking anything. It's making sure I don't damage my BB or intercom because of a poorly constructed circuit that I need some guidance with. =) Aug 03 23:21:03 ah Aug 03 23:21:22 relays can consume a bit of current Aug 03 23:21:32 so you're going to need a BJT/MOSFET Aug 03 23:21:38 definitely Aug 03 23:21:44 that is controlled by a GPIO pin Aug 03 23:21:48 and some protection against voltage spikes Aug 03 23:22:02 Yep sounds good. Aug 03 23:22:11 inductors can be nasty things Aug 03 23:22:25 MOSFET? Is that a solid state relay? Aug 03 23:22:54 it's a metal oxide semiconductor field-effect transistor Aug 03 23:23:03 I was looking at some low voltage reed SPST relays Aug 03 23:23:34 Oh ok, I'm still following. Aug 03 23:23:44 has console-image been replaced with systemd-image? could that be why I'm getting the "Cannot make/remove an entry for the specified session" error? Aug 03 23:23:52 * mru suggests a reed-solomon relay :) Aug 03 23:23:56 to protect against errors Aug 03 23:25:37 mru: if I knew what that was I would use it Aug 03 23:25:53 lucasrangit: sorry, that wasn't for you, nor was it serious Aug 03 23:26:38 Haha, yeah I was just googling it. Lol Aug 03 23:27:08 mru: no problem, but you may be on to something... if I could learn coding theory I probably could learn OpenEmbedded Aug 03 23:38:33 Looking into BJT/MOSFETs now. I have not yet measured the switch on the intercom with my multimeter yet but sort of current/voltages would be too much for a BJT/MOSFET? Aug 03 23:40:12 I don't think the voltage is going to be very much. It's just CAT5 cable that it's wired up with. Aug 03 23:51:59 @mikejones & mru: can I ask why you recommending using transistors over a reed switch? Aug 03 23:52:52 I mean, relay Aug 03 23:53:02 that's not what I said Aug 03 23:53:10 you need a transistor to drive the relay Aug 03 23:53:20 Oh sorry. Aug 03 23:54:09 Looking back, I misread. Thanks for clarifying Aug 03 23:56:29 Would I be right in saying, for my application it doesn't really matter if I use a BJT or a MOSFET? It would probably come down to just cost? Aug 03 23:57:49 And what should I be using to protect against voltage spikes? Aug 04 00:00:58 if you use a mosfet, just be sure to check the voltage used by the original switch to make sure you have enough gate voltage to turn the fet fully on/off Aug 04 00:03:48 @russ: ok thanks so in my application where it will be driving a relay I need to match it with the specs of the chosen relay in order to ensure proper operation? Aug 04 00:06:48 Of the MOSFET that is.. Aug 04 02:29:25 hey guys, i am trying to connect to my beaglebone via USB to ethernet for the first time. I am using OS X Mountain Lion and I couldn't get the ethernet gadget to connect as easily as its explained in the guides, so I deleted it from the System Preferences > Network. How do I get it back? Aug 04 02:30:23 (I have previously connected VIA ethernet OK but thats not practical for what I want to do now.) Aug 04 02:31:10 have you tried plugging into a different usb port on your mac? Aug 04 02:31:24 no i haven't Aug 04 02:31:28 trying now Aug 04 02:31:35 I usually get a new device every time I change ports Aug 04 02:32:33 still on snow leopard though so that might be a little different for you Aug 04 02:33:19 yeah it's not showing me any love when using a different USB port either. Aug 04 02:34:08 I am meant to have the SD card in while trying all this right? Aug 04 02:34:36 yes, if you want the board to actually come up Aug 04 02:34:59 yeah thats what i thought. Aug 04 02:35:04 hrrmmm Aug 04 02:35:42 given that 'no drivers are required' for USB to ethernet on OS X I'm a little stuck. Aug 04 02:40:00 do you think Mountain Lion could be complicating things? Aug 04 02:47:01 i just just got it working again using ethernet. its seems to be working fine otherwise. Aug 04 02:47:11 just USB to ethernet is shagged. Aug 04 02:49:32 hmm, "high gain omni-directional wireless antenna" Aug 04 02:49:38 that's wrong in so many ways... **** ENDING LOGGING AT Sat Aug 04 02:59:58 2012
