Nov 05 09:08:40 Hello everyone, I recently got a beaglebone with a canbus cape but i'm having troubles sending can frames with it (but receiving is OK) I read on http://beagleboardtoys.com/wiki/index.php?title=BeagleBone_CANBus in the known issues section that there is a hardware bug on the cape preventing it to send data on the bus. Does anyone already had troubles with it and found a solution ? Nov 05 09:22:27 glabarthe: it says to bypass the buffer Nov 05 09:33:42 jacekowski: I saw this but before starting to solder things (i am not a hardware person) i was wondering if there was another explanation (probably software) but i will look into this bypassing thing thx. Nov 05 09:34:56 glabarthe: how much did that thing cost? Nov 05 09:36:09 glabarthe: hmm, for price of that thing you can buy working and tested usb to can adapters Nov 05 09:39:38 jacekowski: SInce i have this cape i would prefer using it i'll see if i can do the soldering myself or having it done by the manufacturer Nov 05 10:10:16 greetings, oh front row troll Nov 05 10:12:32 morning trolls and gentlemen Nov 05 10:13:08 mranostay, need to order nick t-shirt like av500 Nov 05 10:14:09 heh Nov 05 10:14:48 * dm8tbr should get a MI style button and a pirate hat. The button would say: "Ask me about: trolling" Nov 05 10:15:14 heh Nov 05 10:15:30 trolling, is it right for you? Nov 05 10:16:02 "Follow me to exact steps for trolling" Nov 05 10:17:03 "I know the exact steps!" "I followed the exact steps and all I got is this lousy T-shirt!" Nov 05 10:17:45 you know we are dorks.. we are talking via irc and we are all under meter away Nov 05 10:18:11 psssst Nov 05 10:18:32 coordinated troll attack on alan_o Nov 05 10:18:53 less troll-fire-power in here though Nov 05 10:19:37 is mru in here? Nov 05 10:20:16 he must be under his bridge Nov 05 10:20:38 does he pack a bridge in his luggage? Nov 05 10:43:55 sorry, I was held up Nov 05 10:44:06 did do some trolling at the tizen booth though Nov 05 10:44:17 they're not giving out the tshirts until tomorrow Nov 05 10:46:25 jkridner, hey i have the serial stuff disabled in energia i'll pus to github later today Nov 05 10:58:26 I downloaded Narcissus builder whith dsplink demos. If a try to call the /etc/init.d/gstdsplink init there's an error about cmemk (invalid address). I did copy preformated uboot-dsplink-512MB-16bpp.cmd.src to /media/BOOT/boot.scr But it seems cat the kernel cmdline is not passed to kernel (cat /proc/cmdline shows sthing else). So where is the right place for this file, if actually loaded by u-boot ? Nov 05 11:27:42 shall the boot.scr loaded by script ? I don't see such cmd in the environment Nov 05 13:30:43 Well boot.scr does not seem to be loaded. according to bootcmd script and startup the uEnv.txt is loaded if the user button has been pressed. Nov 05 13:31:56 At boot I get : CMEMK Error: Failed to request_mem_region(0x86300000, 16777216) Nov 05 13:50:58 <_av500_> cmem Nov 05 13:51:40 <_av500_> what does your /proc/cmdline say? Nov 05 13:51:49 <_av500_> you need a mem= there Nov 05 13:51:57 <_av500_> that reserves space for cmem Nov 05 14:02:29 _av500_: true. I did but not correctly. I did set a mem='' in the uEnv.txt file but is wasn't read via the bootcmd. After reading the 'printenv' I set the optargs that's automatically included in the bootargs Nov 05 14:04:12 Surprisingly Angstrom/dsplink works better that the dvsdk for bbxM Nov 05 14:05:13 * _av500_ is not suprised Nov 05 14:05:16 <_av500_> +r Nov 05 14:05:59 I mean I have a long video that blocks around 2min15s with the dvdsdk and I passed this step with angstrom. Nov 05 14:09:22 hi Nov 05 14:10:48 i would like to make my own beagleboard -xM Nov 05 14:11:17 <_av500_> go on Nov 05 14:11:31 i want to boot it from SATA or NAND flah. can i get any help in this regard Nov 05 14:12:15 I did some videotest with gstreamer and got during playback my screen off. How can I disable it ? I don't have X displayed the sink is directly the omapfb ? Nov 05 14:13:27 viswa: MLO used to boot from Nand. I think you just have to reconfigure it. about SATA I don't know Nov 05 14:14:37 thanks bizulk, sorry i didn't get you what is MLO? Nov 05 14:15:57 viswa: the x-loader. But I think that the boot also has to do with the gpmc selection. You may read the TI doc, for their EVM platforms it is possible to select eMMC, UART, NAND boot Nov 05 14:19:59 bizulk : thank you, ill look in to it. Is there any open design available like Beagleboard-xM? Nov 05 14:21:36 * jkridner looks to see if anyone has reported back from elc-e Nov 05 14:25:15 hi ! does somebody know if the omapfbpplay-dce (distributed codec engine support) support omap3 or is reserved to omap4/5 ? Nov 05 14:25:42 When I launch it I have no display on screen whereas gstreamer tests work fine Nov 05 14:27:23 => according to omappedia that shall not be confused with codec engine, and is reserved to OMAP4/5 as it is based on syslink Nov 05 14:37:27 jkridner: I can report that trolling is going full steam ahead at ELCE Nov 05 14:37:46 <_av500_> +1 Nov 05 14:37:54 <_av500_> bizulk: dce is omap4 Nov 05 14:38:13 <_av500_> and its for old dce, so it does not work any more Nov 05 14:39:00 jkridner: all is well Nov 05 14:41:27 Wish I could have gone to ELCE Nov 05 14:43:29 yay i got the cache working.. Nov 05 14:43:44 now i need to get the dma working on top of that Nov 05 14:44:56 Hi! Documentation/sound/alsa/soc/DAI.txt describes 3 DAIs AC97, I2S and PCM. And in Documentation/sound/alsa/soc/codec.txt they talk about Codec DAI and PCM configuration. TLV320AIC23 can only handle i2s. Right? Nov 05 14:46:46 yegorich wouldnt google answer that for you ? Nov 05 14:47:26 mru: was the default config of L2 inner or outer cache on the omap3/dm37xx ? Nov 05 14:47:32 impossible Nov 05 14:47:58 UnsoloWrk: I try to understand, if PCM has two meaings Nov 05 14:48:39 UnsoloWrk: check the trm Nov 05 14:48:58 mru thanks Nov 05 14:48:59 I'm trying to get si9022 chip working. Video output is functioing and the next step is audio over HDMI Nov 05 14:50:03 yegorich: if its connected to MCASP or MCBSP id suggest using i2s Nov 05 14:50:13 if it supports i2s Nov 05 14:50:26 but thats just my opinion Nov 05 14:51:11 btw mru thanks for all the help with the cache.. Nov 05 14:54:38 As far as I can see davinci-pcm.c will be built for am33xx and not davinci-i2s.c, that's why I think PCM can mean something else Nov 05 14:56:01 arch/arm/mach-omap2/devices.c registers .name = "davinci-pcm-audio", Nov 05 15:00:00 yegorich or perhaps not hard to say i only use the omap + twl slightlty modified on my end (and yes with enough grounding the sound in the twl is perfectly fine) Nov 05 15:04:25 I fear I'll have to write a mfd driver for si9022, so video stuff and audio stuff could be configured via the same i2c address Nov 05 15:16:40 hi any one there to help me?? Nov 05 15:17:08 mranostay: is your talk archived? Nov 05 15:17:23 er, video recorded, slides available, whatever? Nov 05 15:17:29 I want help regarding USB HOST in Beagleboard rev B6 Nov 05 15:17:58 shree_: there are people here. have you read the guide at http://beagleboard.org/chat? Nov 05 15:18:35 from where can i get mini-A to mini-B cable Nov 05 15:19:43 or how to make mini-A cable from normal mini cables?? Nov 05 15:21:03 per http://www.digikey.com/beagleboard: http://www.digikey.com/scripts/DkSearch/dksus.dll?lang=en&KeyWords=10-00003-ND&WT.z_slp_buy=TI_BeagleBoard&cur=USD Nov 05 15:21:34 or http://www.digikey.com/scripts/DkSearch/dksus.dll?lang=en&KeyWords=wm17135-nd&WT.z_slp_buy=TI_BeagleBoard&cur=USD Nov 05 15:24:19 thank you very much for the links... Nov 05 15:25:37 can you please help me to construct my own mini A cable from mini AB cable.. since Mini A cables are costly for me.. Nov 05 15:28:46 I suspect if you had the skills to do it, you'd be able to Google the information. Nov 05 15:30:36 jkridner: I think it was recorded Nov 05 15:35:17 can i make Google a Linkedin skill? Nov 05 15:35:55 ya i googled and i got some sources also but after soldering the cable I am still not able to make it out .. Nov 05 15:37:37 please clear one more thing.. do you think that beagleboard rev B6 support for USB HOST.. without any additional things ..? Nov 05 15:47:07 koen: you around? Nov 05 15:47:14 ya Nov 05 15:52:06 I have installed ubuntu 12.04 in to my beagleboard c3 and I also connected to internet through beagleboard.. please help me in configuring the audio on it Nov 05 15:52:35 means I want to hear audio from beagleboard c3.. Nov 05 16:04:40 help me regarding audio out put in beagleboard Nov 05 16:06:02 morning folks Nov 05 16:06:20 why does debian not spawn dhclient with -nw? Nov 05 16:06:41 or more specifically, why does dhclient not behave like dhcp clients on other distros? Nov 05 16:06:54 if it fails to get an address, it just gives up Nov 05 16:07:29 what would you have it do? make one up? Nov 05 16:08:36 OSX make one up Nov 05 16:08:56 and what's the chance of that working? Nov 05 16:09:25 none, but it knows when it's self-assigned and won't work Nov 05 16:09:36 then why do it? Nov 05 16:10:34 dunno Nov 05 16:11:08 why do half the things apple has decided is "the right way" Nov 05 16:11:30 even if they're right it's not standard Nov 05 16:12:29 and now for the beer trolling! Nov 05 16:27:44 does somebody know if the omapfbplay (so the libavcodec) does use dsp video acceleration. I think this is the case but I have a doubt because with gstreamer to plugin cpu load is about 15% when omapfbplay consumes 40%. Nov 05 16:43:48 mru so from what i can tell the proper procedure for dma write from phys ram to io is cache clean(using lets say MVA), dsb, then dma transfer. To dma from io to ram dma read, cache invalidate mva, then dsb. ram to ram would require both clean and invalidate ? Nov 05 16:44:21 that last one is more of a theoretical thing Nov 05 16:56:21 sorry, work is really busy today Nov 05 16:56:44 mru: i would want it to daemonize and continue trying in the background Nov 05 16:59:02 mru: come on down and troll Nov 05 17:14:33 do somebody know if ffmpeg support any DSP dsplink/tidspbridge acceleration ? I try to find aout but that's not easy Nov 05 17:18:26 bizulk i know the gst plugins work (after you fix all the ifs buts and oddities) Nov 05 17:18:44 hmm simple cache invalidate didnt do the trick Nov 05 17:19:55 UnsoloWrk: I know I did make them work. But I was wondering about the libavcodec but I've seen a thread from ffmpeg-devel and the patch seem to have been rejected Nov 05 17:20:14 ffmpeg guys are quite strict ;) Nov 05 17:20:27 * UnsoloWrk rembers that from doing some ps3 stuff Nov 05 17:46:32 hmm something is wrong with my invalidate.. Nov 05 17:54:40 something tells me that if i do a copy to ram then invalidate that it should say kaboom Nov 05 17:55:46 ? Nov 05 18:04:52 woglinde im trying to do dma after i enabled l2 cache Nov 05 18:05:15 but so far im not even sure im invalidating the right way Nov 05 18:28:16 It's so nice there is a ton of unused cache code in u-boot Nov 05 18:28:27 that does more or less odd things Nov 05 18:29:49 most interesting is how they obtain the cache line size.. Nov 05 18:39:50 argh, DST, feel like lunch was a second breakfast :( Nov 05 18:45:25 can we get rid of that abomination yet? Nov 05 19:08:02 * UnsoloWrk tries to make sense of Russ Nov 05 19:10:04 * djlewis tries to make sense of dst Nov 05 19:10:31 I'm a sunrise to sunset wirk operator Nov 05 19:10:38 work Nov 05 19:18:28 * UnsoloWrk knows that dts is but what is dst Nov 05 19:33:52 djlewis do you also move between north and south pole to make sure it's as little time possible Nov 05 19:34:32 <_av500_> gm Nov 05 19:38:51 hmm, to make it even more interesting the US has 9 time zones Nov 05 19:40:57 well currently if you move far enough north there is no sunset and sunrise Nov 05 19:41:55 * UnsoloWrk is in shock i somehow made dma work with L2 cache and living to tell the tale Nov 05 20:07:23 is the ethernet i/f on the beaglebone gigabit? Nov 05 20:08:08 or better? Nov 05 20:08:13 and would the board be capable of sustained 80 MB/s transfer rates over the network? Nov 05 20:09:16 i'm looking at using it as a data collection system.. Nov 05 20:09:41 UnsoloWrk: I dont work 24 hr. 7day/week, thanks Nov 05 20:09:52 would a modern laptop be capable of storing 80 MB/s? Nov 05 20:09:53 no tht's 7sb Nov 05 20:10:02 no tht's usb !(!8+ Nov 05 20:10:10 no tht's usb AFAIK Nov 05 20:10:10 receiving/storing Nov 05 20:10:21 meh, i hate my phone Nov 05 20:10:23 wow, 640Mbit/s? Nov 05 20:10:29 yup. Nov 05 20:10:59 just cuz there specs does not mean a product meets them Nov 05 20:11:00 only 64 percent of gigabit ethernet - easy, right? Nov 05 20:11:10 :) Nov 05 20:11:28 just inquiring / scoping things out. Nov 05 20:11:47 beaglebone ethernet is 10/100 Nov 05 20:11:53 doh! Nov 05 20:11:54 not 10G or anything like that Nov 05 20:12:05 darn. Nov 05 20:13:36 i'm thinking of basing a VOR radio around it. Nov 05 20:13:53 VHF Omnidirectional Range Radio Nov 05 20:15:23 why would you need gbit for VOR? Nov 05 20:15:41 you certainly would not for the VOR function Nov 05 20:15:59 i was hoping i could also simultaneously use it as a data collection system Nov 05 20:16:00 dm8tbr: because metal? *SCNR* Nov 05 20:16:31 LetoThe2nd: my metal detector just asploded, you now owe me a beer! Nov 05 20:16:57 i'm thinking of a direct-conversion scheme running at 40M samples/second, 16 bits per sample. Nov 05 20:17:10 * LetoThe2nd tries not to imagina an "asploding" metal detector Nov 05 20:17:37 don't see why not if you build the right expansion board Nov 05 20:18:06 32 bit wide bus... that's a 2MHz clock rate Nov 05 20:18:14 LetoThe2nd: yea, duck and cover because all of the metal shards... Nov 05 20:18:30 ds2: yeah, but how to get it out of the sitara? Nov 05 20:18:46 to a laptop, e.g. Nov 05 20:18:49 very very carefully of course Nov 05 20:18:53 of course :) Nov 05 20:19:21 dm8tbr: yeah... Nov 05 20:19:25 details are left as an exercise for the reader. Nov 05 20:19:27 nm - it's not that important - just pie-in-the-sky thinking. Nov 05 20:19:39 It Would Be Nice(TM) Nov 05 20:19:43 dm8tbr: guess you are also ending the evening slowly? Nov 05 20:20:21 ea Nov 05 20:20:31 yea Nov 05 20:20:39 dm8tbr: how many casks have you guys emptied so far? Nov 05 20:21:30 * LetoThe2nd is gone then again. seeya all tomorrow(in person or maybe here.) Nov 05 20:22:12 ds2: plenty, I guess Nov 05 20:45:04 dm8tbr haha Nov 05 21:55:30 does anyone have advice on fixing nand boot issues? Nov 05 21:56:39 it just works. Nov 05 22:02:08 dodn't do it? Nov 05 22:05:44 any ideas what 60 refers to? Nov 05 22:06:54 cpu boot code? omap3530 for instance is 40something Nov 05 22:08:30 ok, im having trouble getting past the nand boot to get to the u-boot prompt using the user button. Nov 05 22:08:49 which board? Nov 05 22:08:57 xm Nov 05 22:09:09 doesn't have NAND in most cases Nov 05 22:09:29 you need an SD that properly configured Nov 05 22:10:39 ah ok, i was on the wrong track... I keep flash sd ards with imgs, Nov 05 22:28:52 anyone knows how to resolve this spl: mmc init failed: err - -19 Nov 05 22:28:52 ? Nov 05 23:03:57 mru: where are you guys? Nov 05 23:06:11 anyone downstairs at the hotel bar? Nov 06 00:27:55 don't have a board here, is omap3530 virtual address starting from 0xc or 0x80000000 Nov 06 00:28:07 i mean 0xc0000000 Nov 06 00:28:35 ok i think virtually it's 0xc, physically it's 0x8 **** ENDING LOGGING AT Tue Nov 06 02:59:58 2012
