**** BEGIN LOGGING AT Mon Aug 20 02:59:59 2012 Aug 20 03:32:52 will the libgles stuff from the angstrom repo work in a custom kernel? Aug 20 04:43:13 Hi guys, I am new to beagle series. I want to know am i possible to run LAMP server, java and python on BeagleBone Aug 20 04:52:57 not sure what you can expect in the way of performance with such a setup, the SD storage is pretty slow Aug 20 05:12:12 sd storage is fine Aug 20 07:03:32 woot, finally got GLES running on my custom kernel/board Aug 20 07:42:22 thurbad: POIDNH Aug 20 09:50:22 hi Aug 20 09:54:02 Im not sure if I found a bug in rtc-twl.c running on a beagleboard. Aug 20 09:54:10 Is anybody interested in? Aug 20 10:07:47 hey Aug 20 10:25:31 I have gst-dsp working on my omap3 (kernel 3.5.2) but does anybody have ideas why I'm getting these errors frequently during the video encode: Aug 20 10:25:34 memory_regain_ownership: dma info doesn't match given params Aug 20 10:25:37 proc_end_dma: InValid address parameters b6302e00 4c80 Aug 20 10:31:48 kulve: no idea Aug 20 10:31:57 also, almost nobody here using gst-gst Aug 20 10:32:02 gst-dsp Aug 20 10:32:30 you are using the other dsp framework? Aug 20 10:32:54 well Aug 20 10:33:32 the ti proposed gst-ti goes via the other framework Aug 20 10:33:46 and personally I have used both, but not with such a "new" kernel... Aug 20 10:51:10 https://github.com/modmaker/am335x_pru_package/commit/e013e885725384c8d6a197bf35071c4dee9dae82 Aug 20 11:34:56 beep beep Aug 20 11:35:01 eins zwo Aug 20 12:01:40 koen: Sttt! Let the sleeping dogs lie! Aug 20 12:11:05 Hi! How to build Angstrom with Enlightment windows manager? Is it already a part of Angstrom? Aug 20 12:11:21 What other build targets do I have beside console-image, systemd-gnome-image etc.? Where can I find the list of them? Aug 20 12:11:30 Hell Aug 20 12:11:40 *Hello ? Aug 20 12:11:49 So far i could get console-image built and working using http://www.angstrom-distribution.org/building-angstrom Aug 20 12:12:54 Can anybody help me with beaglebone GPIO ? Aug 20 12:13:16 I want to read beaglebone input through sysfs. I did following steps: echo 7 > /sys/kernel/debug/omap_mux/gpmc_ad6 echo 38 > /sys/class/gpio/export echo in /sys/class/gpio/gpio38/direction cat /sys/class/gpio/gpio38/value 0 always ' 0 ' , if I give the input 3.3v also its showing 0. what may be the problem ? But output to this pin is working fine. Aug 20 12:13:51 sorry for messing, here it is again Aug 20 12:14:08 I want to read beaglebone input through sysfs. I did following steps: Aug 20 12:14:22 echo 7 > /sys/kernel/debug/omap_mux/gpmc_ad6 Aug 20 12:14:31 echo 38 > /sys/class/gpio/export Aug 20 12:14:44 echo in /sys/class/gpio/gpio38/direction Aug 20 12:14:54 cat /sys/class/gpio/gpio38/value 0 Aug 20 12:14:58 always ' 0 ' , if I give the input 3.3v also its showing 0. what may be the problem ? But output to this pin is working fine. Aug 20 12:16:50 jeshu, i vaguely remember something about a setting related to if it wanted an input voltage vs grounded Aug 20 12:19:03 Chainsawbike, Actually what I did is I gave beaglebone's P8 3rd pin which is 3.3 volts into this pin, and also tried with gnd but it doesnt work :( Aug 20 13:13:03 can the easycap videocapture drivers (compiled) be located for beagleboard xm ? Aug 20 13:18:50 http://code.google.com/p/easycap-somagic-linux/ Aug 20 13:22:14 av500, what is your secret? Aug 20 13:22:23 ? Aug 20 13:22:32 to locating them! Aug 20 13:22:33 if I told you, would it still be= Aug 20 13:22:35 if I told you, would it still be? Aug 20 13:22:40 *sigh* Aug 20 13:22:53 the force strong with this one it is Aug 20 13:23:00 * mdp returns to debugging "advanced pointer code" Aug 20 13:23:08 http://forum.easycap.co.uk/index.php?topic=448.0 Aug 20 13:25:23 * mdp hopes to be PMed the sekrit Aug 20 13:25:34 mdp: wow, _two_ pointers in the same function Aug 20 13:25:39 that is some serious shit, man Aug 20 13:25:47 lol Aug 20 13:26:14 mru, I'm stuck on grasping the advanced concept...need to stick with javascript Aug 20 13:27:18 mru, a friend was accused by a co-worker of writing code with "advanced pointer usage"...the idea remains stuck in my head forever. :) Aug 20 13:27:48 what made it advanced? Aug 20 13:29:52 apparently, any typical constructs in C are advanced...I did not get to directly see it but he said he was just doing normal container references in his patch Aug 20 13:30:15 yeah, I know the kind of people who say such things Aug 20 13:30:22 I suggested he could explain the exact steps to understand this advanced pointer usage Aug 20 13:32:28 I can't imagine how these types are able to grasp threads and processes :( Aug 20 13:34:34 av500: thanks Aug 20 13:36:59 av500: id have to compile from source these arent binaries Aug 20 13:38:36 mdp: they're not Aug 20 13:39:25 Hi! How to build Angstrom with Enlightment windows manager? Aug 20 13:39:34 av500: any idea? Aug 20 13:42:43 yegorich: no idea Aug 20 13:42:48 is it in the feeds? Aug 20 13:43:28 av500: where can I check this? I'm just learning OE. Aug 20 13:44:03 av500: at least I couldn't find it as a part of targets like console-image etc. Aug 20 13:44:28 av500: but I have seen lots of dead links pointing to such an image for testing Aug 20 13:46:34 koen: ^^^ ??? Aug 20 13:48:16 av500: id have to compile from source these arent binaries ? Aug 20 13:48:24 I guess so Aug 20 13:59:50 yegorich: use narcissus http://narcissus.angstrom-distribution.org/ Aug 20 14:00:23 yegorich: choose X11, then Enlightenment Aug 20 14:17:40 So I'm out of ideas and need some help. I'm using the mainline kernel + patches from https://github.com/beagleboard/kernel/tree/beaglebone-3.6/ and I can't seem to make the UARTs work, (other than of course UART0, which is the console). Aug 20 14:18:00 So that new kernel does pinmuxing from the device tree Aug 20 14:18:26 and in the device tree there are some pinmux items set up for the LEDs Aug 20 14:18:35 so I figured I could do similarly. Aug 20 14:18:55 Unfortunately, I've failed to find any setting that works. Aug 20 14:19:59 With a meter, I just sit at 2.5V on TXD and RXD, even when catting stuff to the port from the bone (cat /dev/urandom >/dev/ttyO2) Aug 20 14:20:06 tried with UART1 and 2 Aug 20 14:21:11 alan_o: meter may not be fast enough Aug 20 14:21:20 tried running a getty on it (because that's often the easiest way to configure the port settings to something usable). No worky either. I can getty with the same command on ttyO0 and it will create a new getty for me, so I know I'm doing the getty right Aug 20 14:21:21 you should really use a scope for that kind of thing Aug 20 14:21:59 jacekowski: yeah, I should. No doubt. If I only had a scope..... Aug 20 14:22:13 But I've done testing with the meter before on uarts Aug 20 14:22:44 when idle, it shows SPACE and when transmitting it goes somewhere between mark and space Aug 20 14:23:13 So maybe I should check my premises here..... Aug 20 14:23:49 UARTn in the TRM and board documents refers to /dev/ttyOn for values of n 0 - 4 ? Aug 20 14:24:28 UART0 seems to match ttyO0.... the other ones I haven't checked the addresses in the device tree. Maybe I should. Aug 20 14:25:26 The other premise I have is that I don't have to do anything other than set the pinmux to make the uart functionality appear on those pins. Aug 20 14:26:34 i seem to recal that it was number 2 not 0 Aug 20 14:26:51 jacekowski: the console? Aug 20 14:26:53 one bone? Aug 20 14:27:00 on bone? Aug 20 14:27:00 on bb Aug 20 14:27:12 but i may be wrong on that Aug 20 14:27:13 yeah, on beagleboard it's O2 Aug 20 14:27:21 on beaglebone it's O0 Aug 20 14:27:31 well i would try 2 as well Aug 20 14:27:48 well the console works fine.... Aug 20 14:28:03 on bone it's wired to an FTDI and out the USB connector Aug 20 14:28:12 the console is. Aug 20 14:28:17 I'm trying to get the other UARTs working Aug 20 14:28:32 So there's a couple websites talking about it. Aug 20 14:28:56 unfortunately they use the OMAP pinmux which doesn't seem to be what is used on the mainline kernel at the link I sent above Aug 20 14:29:43 where did you set up your pinmux ? Aug 20 14:33:03 in the device tree Aug 20 14:33:20 I just put my values in with where the LED stuff was Aug 20 14:33:43 keep in mind, this isn't the TI kernel, it's this one: https://github.com/beagleboard/kernel/tree/beaglebone-3.6/ Aug 20 14:36:34 so you tried setting it from the sysfs? Aug 20 14:36:43 I don't have it in sysfs Aug 20 14:37:08 the sysfs stuff that's exported, at least the stuff people talk about online, is specifc to omap-pinmux Aug 20 14:37:21 the kernel at the link above uses pinmux-single Aug 20 14:38:15 you still have to set up the muxing Aug 20 14:38:30 indeed Aug 20 14:38:33 ok, can you link to codewere you did the muxing? Aug 20 14:38:39 and I do it in the device tree Aug 20 14:39:04 let me pastebin it Aug 20 14:40:21 http://pastebin.com/ghhL575E Aug 20 14:40:25 So that's from the DT Aug 20 14:40:46 and the one line has the comment cut off. Don't worry, it does compile :) Aug 20 14:41:05 actually a bunch is cut off Aug 20 14:41:06 hang on Aug 20 14:41:11 * alan_o makes his terminal bigger Aug 20 14:41:55 http://pastebin.com/knbT18Q5 Aug 20 14:42:21 So the acutal values for UART2 are probably not right Aug 20 14:42:32 "grow a terminal like a hacker in only two weeks"? Aug 20 14:42:33 by the end last night I was just trying stuff trying to see a different result Aug 20 14:43:34 mru: I wish I could grow a VT320. I used one last year. Was really nice. I think it'd be cool to have one in the garage, hooked up to my main PC. Aug 20 14:44:08 mru: I think it takes too much watering and whatnot to grow one of those.... easier to buy on ebay Aug 20 14:44:09 I'm using rcn-ee Ubuntu 11.10 image on BeagleBoard XM. I was recently trying to upgrade to distribution to 12.04 but noticed that after completing the command didn't work. It gives error as no such command. How can I upgrade to 12.04 in such case? Aug 20 14:45:50 Or is there anything I am missing to upgrade distribution to 12.04 from command-line? Aug 20 14:53:21 have you tried using the TI's pinmux utility to generate the values? Aug 20 14:53:23 Hello people. I need some advice on a simple thing. I want to avoid writing the ./ from inside a folder (in my case /home/root) so that all the commands present in there can be typed in without ./ Aug 20 14:54:06 I tried to add a line to a startup script Aug 20 14:54:24 export PATH=/home/root/:$PATH Aug 20 14:54:34 but it doesn't work. Aug 20 14:54:47 I have Angstrom on Beagleboard. Aug 20 14:55:12 Any suggestions? Aug 20 14:56:47 you could try export PATH=./:$PATH instead Aug 20 14:57:33 I know that works for local paths Aug 20 14:57:34 where did you set the PATH, what startup scripts? Aug 20 14:58:16 It's a script I have in the root folder. It's launched at startup. It works for all the other commands. Aug 20 14:58:30 if the script is executed rather than sourced, your exports won't carry over Aug 20 14:58:56 is it launched when the board starts or when your shell starts? Aug 20 15:01:53 When the shll starts. Aug 20 15:01:58 Definitely. Aug 20 15:03:58 does echo $PATH show that /home/root is there? Aug 20 15:04:26 No. Aug 20 15:04:54 If I give the command manually, like PATH=/home/root/:$PATH Aug 20 15:04:58 then it works. Aug 20 15:05:23 I just don't know how to set this automatically at startup time Aug 20 15:09:06 can i connect my mobile which acts as a webcamera to my beagleboard xm for remote survillance over internet? Aug 20 15:09:56 i guess that your shell is busybox builtin ash which might read $HOME/.profile on start Aug 20 15:10:14 can i connect my mobile which acts as a webcamera to my beagleboard xm for remote survillance over internet? Aug 20 15:10:21 I'll try to create it in a minute Aug 20 15:10:24 so place your export line there an give it a shot Aug 20 15:10:31 ok Aug 20 15:11:09 please help me guys Aug 20 15:12:41 does your mobile have linux support for such a feature? Aug 20 15:13:59 no....i am able to use my mobile as a webcamera......i am able to gmail voice chat with my friend Aug 20 15:15:17 ? Aug 20 15:16:52 my mobile is micromax X276 Aug 20 15:19:24 no, you cannot do that Aug 20 15:20:50 thurbad: What is TI's pinmux utility ? Aug 20 15:21:38 please keep the conversation on channel, don't msg everyone with the same question Aug 20 15:21:55 pradeep I mean Aug 20 15:22:12 it's a windows app from TI that helps set up pinmux values Aug 20 15:22:13 Hey adj, I tried to create the .profile with "export PATH=/home/root/:$PATH" Aug 20 15:22:20 but it doesn't work. Aug 20 15:23:38 Where is the default PATH variable setup? Knowing this might solve. Aug 20 15:23:40 thurbad: Umm, was that your reply to my question to fix upgrade issue? How will that help? :S Aug 20 15:24:08 steak_: hmm, busybox might read also /etc/profile when shell starts. Is there such a file? Aug 20 15:25:37 for ubuntu on beagleboard xm apt-get install gstreamer0.10 isnt working keeps coming back with packages not found is there a reason for that? Aug 20 15:26:43 deffrag: no it was to alan_o Aug 20 15:29:32 thurbad: No, I haven't used used the pinmux utility. Looking at it now Aug 20 15:34:01 I'll take a look adj - thanks 4 help so far Aug 20 15:34:10 back in 1' Aug 20 15:35:07 did you put .profile inside ~/ Aug 20 15:35:48 which webcamera can i interface tomy beagle boardxm? Aug 20 15:37:05 arcanescu you have not included all repos? Aug 20 15:37:23 any camera that is supported by linux. Best bet is to buy uvc compatible camera Aug 20 15:37:50 woglinde: im not sure.... i just did this: apt-get install gstreamer0.10 gstreamer0.10-ffmpeg gstreamer0.10-plugins-ugly gstreamer-tools ivtv-utils Aug 20 15:38:00 it went on to say 404 notfound on many packages Aug 20 15:38:10 arcanescu apt-get update Aug 20 15:38:14 before Aug 20 15:38:41 adj but you will get lower framerates Aug 20 15:38:55 with uvc cams Aug 20 15:38:57 woglinde: i did ... Aug 20 15:39:05 let me paste the package it complains about Aug 20 15:39:11 arcanescu hm than the repos are borken Aug 20 15:39:49 Hey adj I found /etc/profile added my path to the PATH variable export in the script and it works Aug 20 15:39:56 Big thanks. Aug 20 15:40:07 Logitech Webcam?? Aug 20 15:40:17 woglinde: i thought so it isnt something complex really... but let me try it again maybe im being stupid Aug 20 15:40:30 missing something out Aug 20 15:40:55 @adj Big thanks. Aug 20 15:41:24 he crofton Aug 20 15:44:18 btw camera http://www.oz9aec.net/index.php/gumstix-overo/381-video-recorder-update Aug 20 15:44:33 and the problem with gstreamer is the colorspace conversion Aug 20 15:44:44 I found in another gumstick thread Aug 20 15:45:06 woglinde: slower, really? didn't know that. How slow? I guess they still beat most $random cheapo usb cameras Aug 20 15:45:29 adj 15 vs 30fps you get with ti cams directly connected Aug 20 15:45:46 I do bot find the colorspace posting at the moment Aug 20 15:45:49 pradeep:http://blog.galemin.com/2012/03/buildroot-2012-02-for-beagleboard-xm-with-li-5m03-mt9p031-camera-support/ Aug 20 15:45:59 this has demo images for interfacing to the camear aswell Aug 20 15:46:05 *camera Aug 20 15:46:51 woglinde: it started to work not repos not broken its me :( Aug 20 15:48:39 aranescu so you forgot apt-get update Aug 20 15:48:42 before Aug 20 15:48:53 i can assure you i did apt-get update Aug 20 15:49:06 otherwise 404 on so many packages do not occure Aug 20 15:49:25 that is true... Aug 20 15:49:30 can you pastebin your sources.list somewhere ? Aug 20 15:49:31 and hence the question here Aug 20 15:50:08 (and also the full log of your attept) Aug 20 15:50:22 ogra_: its busy trying to get the packages now.... but i think it might be the update Aug 20 15:53:20 hm damn I do not find this colorconversion posting Aug 20 15:53:24 again Aug 20 15:57:37 * ogra_ hands woglinde some red/green 3D glasses Aug 20 15:58:03 (analog color conversion :) ) Aug 20 15:59:29 ogra hm I think it was with opencv Aug 20 15:59:47 slow framte rate with uvc and opencv Aug 20 16:01:02 but this looks good to for uvc stuff Aug 20 16:01:04 http://www.oz9aec.net/index.php/gstreamer Aug 20 16:01:10 as information source Aug 20 16:03:45 i used friendly arm in that i suceeded to transmit webcamera(video signals) connected to friendlyarm to another place.My question is Using same codes that i used in friendlyarm can be used in beagle board? Aug 20 16:05:31 pradeep uvc cam? Aug 20 16:05:53 than you can use the same gstreamer pipeline Aug 20 16:06:02 wat about the codes? Aug 20 16:06:12 what codes? Aug 20 16:06:21 best you post your gstreamer line Aug 20 16:06:23 * ogra_ guesses he means codecs Aug 20 16:06:38 ogra I give up in guessing Aug 20 16:06:46 :) Aug 20 16:06:50 either he can make his question clear Aug 20 16:06:59 or I will not help Aug 20 16:07:00 codes to interface and to display over a internet Aug 20 16:07:46 pradeep should be, but again postin your gstreamer line and I can tell you for sure Aug 20 16:08:11 k sir i will try using uvc and gstreamer Aug 20 16:09:25 o.O Aug 20 16:09:33 SIR Aug 20 16:09:39 Woglinde Aug 20 16:09:47 like Sir Richard Branson? Aug 20 16:09:55 pradeep how did you capture the stream on arm friendly board? Aug 20 16:12:04 wait sir i will give description Aug 20 16:30:03 i compiled my own plugins (for angstrom) , i switched to ubuntu now they dont seem to load Aug 20 16:30:27 http://code.google.com/p/s3c2440camera/ Aug 20 16:30:27 is this a 'not compiled for the right kernel' fault? Aug 20 16:30:28 http://code.google.com/p/mjpg-streamer-mini2440/ Aug 20 16:30:42 http://sourceforge.net/projects/mjpg-streamer/ Aug 20 16:53:42 pradeep you need to compile the stuff for beagle Aug 20 16:58:56 thurbad: Did the pinmux by hand in a driver, and now it works Aug 20 16:59:10 alan_o: cool Aug 20 16:59:28 thurbad: looks like the device tree stuff isn't working right, or I did it wrong or something, maybe koen would be interested in that. Aug 20 17:00:02 in fact, koen, I have a hard time understanding how the values you have in there for the leds make sense with respect to the comments. Aug 20 17:01:06 so thurbad, the key was, reboot to the TI kernel, do it the published way, validate that all my hardware is connected correctly and works, then eliminate that as a possibility. I always end up with too many variables..... Aug 20 17:01:46 thurbad: thanks for your help earlier. the pinmux tool validated some of my assumptions and gave me more stuff to try (eliminating even more variables) Aug 20 17:08:38 alan_o congrats on getting it working Aug 20 17:16:33 is there something that will read/write in my beaglebone's microsd card that's more reliable than a microsd card? Aug 20 17:16:56 ext2 and a lot of unwritten data is not an acceptable alternative to a reliable storage medium Aug 20 17:22:08 koen: Aug 20 17:22:11 koen: ping Aug 20 17:23:46 jkridner_: fyi, I moved over the new content from the CC wiki to the elinux.org wiki Aug 20 17:24:28 wmat: did you put in easter eggs in the content? Aug 20 17:25:00 prpplague: but of course. Note: Don't Click the BunnyCape ;) Aug 20 17:25:37 hehe Aug 20 17:40:38 alan_o: you can see me complaining about those silly numbers on the l-o and dt mailinglists Aug 20 17:40:55 alan_o: from what I can see it's almost the same as the raw memory addresses Aug 20 17:41:54 koen: you have spam Aug 20 17:42:31 * koen checks the stock room Aug 20 17:42:35 nope, no spam there Aug 20 17:52:15 koen: hehe Aug 20 17:52:26 koen: let me know what you think of that BoB Aug 20 17:56:42 Does somebody have experience using the SGX530 module on the beaglebone? Does it make sense to use it to accelerate floating point matrix operations? Aug 20 17:56:42 koen: indeed, it's just raw memory access. I don't really understand the point. However, when I put my own numbers in there, it doesn't even seem to do that. Aug 20 17:57:11 Hitsch: i'd say no, anyway you've got a dsp Aug 20 17:58:43 koen: and the other thing is, the numbers in there for the LEDs are the defaults at power-up if I read/remember the datasheet correctly, so it's possible that something in the DTS is not configured correctly and it isn't processing that section at all Aug 20 17:59:14 alan_o: I need to refresh a number of patches with their latest versions Aug 20 17:59:24 alan_o: so it might be just a buggy pinctrl driver Aug 20 17:59:37 koen: or that Aug 20 17:59:50 koen: so are they getting close on DMA? Aug 20 18:00:04 koen, how was lowlands? Aug 20 18:00:05 was that mdp? Hard to remember. Aug 20 18:00:05 alan_o: yes Aug 20 18:00:13 Crofton: hot, dusty and a ton of fun Aug 20 18:01:19 alan_o, davinci-specific patches are up, I'm working on v2 atm and then was going to try a wip hack for am335x Aug 20 18:01:55 phh: thanks. what's the reason? Aug 20 18:02:13 there's several issues that need handled cleanly but I figure something wip will be useful for those wanting to use mmc Aug 20 18:02:35 Hitsch: i don't know, that's just a feeling :p anyway i'm pretty sure dsp would be faster than using the gpu Aug 20 18:02:37 mdp: and spi (ie: me) Aug 20 18:02:55 "PIO SPI ought to be good enough for anybody" ;) Aug 20 18:03:05 mdp: does it work? Aug 20 18:03:11 alan_o, yeah, that too, though I know there's a simple hack to run it pio only Aug 20 18:03:30 yeah, I can grab a link if somebody doesn't beat me Aug 20 18:03:34 I missed that memo apparently. I've been using spi-gpio. I can't complain. Aug 20 18:03:54 ah, so it got up to 24C? Aug 20 18:03:56 ahh, like an rpi user ;) Aug 20 18:04:04 alan_o, let me look...sec Aug 20 18:04:38 alan_o, https://patchwork.kernel.org/patch/1235631/ Aug 20 18:04:43 mdp: the difference btw me and an RPi user is that I'm not bit-baning it from userspace, and didn't have to write any code :) Aug 20 18:04:51 mdp: koen gave me a hard time about that too..... Aug 20 18:05:00 alan_o, really, j/k there..I know that's insulting at best Aug 20 18:05:12 hah, yeah I know. Aug 20 18:05:45 the difference with mcspi is that it already had all the pio paths in place to be able to make the decision to use PIO under the magic threshold value Aug 20 18:05:47 I had it on the real SPI when on the TI kernel, but had to switch away for the mainline stuff. Aug 20 18:05:56 whereas omap_hsmmc just has nothing of the sort to run PIO only Aug 20 18:06:21 what do you mean by magic threshold value? Aug 20 18:06:30 phh: dsp on am 3359? Aug 20 18:06:40 Hitsch: baah Aug 20 18:07:58 alan_o, DMA_MIN_BYTES=160 Aug 20 18:08:18 alan_o, spi transfers < 160 use PIO only Aug 20 18:08:24 in the mcspi driver Aug 20 18:08:47 oh, it switches between DMA and PIO in real time, not just deciding one or the other at startup. Aug 20 18:08:51 in davinci-land, it's interesting that even a 1 byte transfer has the entire dma setup/teardown overhead :( Aug 20 18:09:30 alan_o, exactly, so that path to use PIO was already there, just not engaged 100% of the time Aug 20 18:09:45 so the trivial patch just allows it to continue on if dma channel init fails Aug 20 18:09:50 phh: haha, am I sleeping? I got the gpu, sgx and pru Aug 20 18:10:00 oh.... so that's why it was in and then taken out. It worked sometimes and not others. Aug 20 18:10:02 Hitsch: sgx is the gpu Aug 20 18:10:41 mdp: all my transfers are small (<130), so I could have been using it the whole time probably then. Aug 20 18:10:47 mdp: if I had added it to the device tree. Aug 20 18:11:39 well, without the patch, the init would fail when it couldn't requsest a dma channel... Aug 20 18:12:25 mdp: I guess I should read the patch :) Aug 20 18:13:01 phh: sorry, ment the arm Aug 20 18:13:32 hmm so I guess that doesn't answer why it was in and then out... not that it's keeping me up at night. thanks for the link. I'll give it a go. Aug 20 18:14:04 alan_o, semantics of how it should be handled IIRC Aug 20 18:18:25 alan_o, IMHO koen's 3.6 series should have that patch added temporarily just to make mcspi work Aug 20 18:20:34 working on it :) Aug 20 18:21:04 can someone hand me the magic for the .dts to make spi work? Aug 20 18:23:34 koen: how similar would it be to what's already in omap3.dtsi? Aug 20 18:23:44 no idea, sorry Aug 20 18:30:54 stupid question but is there a way to opkg install easy cap driver? Aug 20 18:32:10 Hello... Two questions about beagle xM Aug 20 18:32:28 the limit is one for this channel Aug 20 18:32:54 I thought we voted to raise it to 1.414, as a nice approixmation to sqrt(2)? Aug 20 18:33:14 mranostay: if that was for me ive not consumed my 1 Aug 20 18:34:00 1) Can uart be configured with higher baud than 115200? Aug 20 18:35:11 2) Does someone know how to fix usb webcam feeds(usb isochronus transfer error or something like that)? Aug 20 18:35:54 koen: if it were me, and I'm not a dts expert by any means, I'd try it with this: http://pastebin.com/Cxedgifi Aug 20 18:35:57 2) my logitech webcams mjpeg video feed is glitchy Aug 20 18:36:39 Lauri___: do you have the same problem on a PC? Is it beagle-specific? Aug 20 18:37:09 no problems on pc. Aug 20 18:37:34 as far as i know then it is a bug in kernel Aug 20 18:38:55 Lauri___: or hardware, or cabling in between, or hubs... Aug 20 18:39:13 this: https://groups.google.com/forum/?fromgroups=#!topic/beagleboard/x8MT086mKe0 Aug 20 18:39:57 no hubs Aug 20 18:40:16 i have 2 identical webcams (logitech's), and they both behave similarly Aug 20 18:41:05 again, there were no problems when using pandaboard, but I need it to work with beagle Aug 20 18:42:38 what is the voltage output level on gpio pins on beaglebone ? Aug 20 18:43:23 is voltage level on beaglebone and on beagleBOARD Aug 20 18:43:38 the Bone is a 3.3V interface, Boards, 1.8V Aug 20 18:43:54 is there any doc on beagle bone interface to servo motor Aug 20 18:44:02 google has some Aug 20 18:44:09 djlewis Thanks! Aug 20 18:44:22 Lauri___: sounds likely to be hardware or kernel then. But that doesn't help you. Actually the error kind of sounds like hardware. If there are errors on the bus, all traffic besides iso will get re-transmitted, so you likely won't even notice. Aug 20 18:44:45 BTW video4l works with beagleBONE Aug 20 18:44:58 last time some one said here that it wont work Aug 20 18:45:30 Lauri___: what is the video spec you're using? Aug 20 18:45:50 mjpg output, 640x480, 30fps i think Aug 20 18:46:06 png 640X480 Aug 20 18:46:35 video4linux2 Aug 20 18:47:19 alan_o: "If there are errors on the bus, all traffic besides iso will get re-transmitted, so you likely won't even notice." yes, because only iso hasnt error checking, right? Aug 20 18:47:48 so any schematic(gpio) for beagleboard would work for beaglebone too ? Aug 20 18:48:16 i think the cause may be: unstable usb clock or kernel configuration error Aug 20 18:49:29 ================================================================== Aug 20 18:49:31 Lauri___: iso should have crc checking, but if packets are lost they are not retransmitted. this is because iso is designed for real-time streaming type applications where late data is just as good as no data. Aug 20 18:49:42 more likely it's the strain on the cpu handling that much bandwidth Aug 20 18:49:56 or that Aug 20 18:50:03 what's your CPU usage look like? Aug 20 18:50:12 barely Aug 20 18:50:21 < 10% Aug 20 18:54:45 alan_o, mdp: spi-pio patch is in, will patch the dts later Aug 20 18:55:12 Thanks! I'll test it tonight Aug 20 19:03:17 koen, cool, thanks Aug 20 19:03:49 updated to rc2 as well Aug 20 19:11:16 mru: #rpi is just a fountain of laughs Aug 20 19:11:32 mru: is there any way to take advantage of gpio interrupts in bash? Aug 20 19:12:25 what's so funny? I use gpio interrupts in bash all the time ;) Aug 20 19:13:09 hehe Aug 20 19:13:19 can you say 'gpio keys'? :D Aug 20 19:14:52 indeed Aug 20 19:18:04 ds2: hehe no one answered him Aug 20 19:27:21 how I spent my Sunday.. http://djlewis.us/files/projects/AmateurRadio/tower/towertakedown-1.jpg Aug 20 19:28:30 prpplague: it's so much fun that they banned me Aug 20 19:28:32 three times Aug 20 19:28:43 the third time I didn't even say anything Aug 20 19:29:00 mru: they find you so charming ;) Aug 20 19:29:28 I got banned for saying "is there any non-shit usb implementation?" Aug 20 19:29:43 like I said, Charming :) Aug 20 19:30:16 if they can't take straight and to the point talk then who needs them ;) Aug 20 19:31:40 it's that toy sheriff reggieuk that's the big asshole Aug 20 19:31:52 the rest are mostly just clueless Aug 20 19:32:16 he might be trying to keep intellect above his out of play Aug 20 19:58:51 koen: ping Aug 20 19:59:21 mru: get banned again? Aug 20 19:59:35 not since the other day Aug 20 19:59:40 haven't been back Aug 20 19:59:48 I'm assuming the ban is still in place Aug 20 20:00:01
