**** BEGIN LOGGING AT Tue Jan 31 02:59:58 2012 Jan 31 04:16:33 anyone using this distro? trying to figure out how to ssh into Beaglebone with it installed https://wiki.ubuntu.com/ARM/OMAP Jan 31 04:18:10 jvcleave: try #ubuntu Jan 31 04:29:27 looking at this page Jan 31 04:29:30 http://dev.gentoo.org/~armin76/arm/beaglebone/install.xml Jan 31 04:29:52 Due to a bug on the USB driver used in the beaglebone, once you unplug the first USB device, it won't detect any new USB device. Jan 31 04:29:52 The quick fix to make the USB port work again, you must do: Jan 31 04:29:52 # echo F > /proc/driver/musb_hdrc.1 Jan 31 04:30:03 Is that still true? Jan 31 06:19:34 <_av500_> why not just try it? Jan 31 06:20:17 / Jan 31 06:37:19 hi, may i know how to rebuild kernel for beagleboard? what is the software I need and if there is any tutorial that I could follow on? :) Jan 31 06:50:00 you need a native gcc for arm or a cross-gcc and, obviously, the kernel Jan 31 06:51:08 you might try compiling a kernel for a pc first, then start with building one for the beagle. Jan 31 06:51:37 getting linux-experience is much easier using a pc than a beagle Jan 31 07:34:27 http://blog.makezine.com/2012/01/30/electro-wire-stripper/ Jan 31 08:10:53 DJWillis: every ES rev has its own package now, so the old ES2 will stay in the feeds Jan 31 08:12:17 koen: ahhh, ok, little harder to work out for an 'on device' image that won't nessessarly have net access but that makes perfect sense :D. Jan 31 08:14:33 DJWillis: the revision script might need to fixup some extra symlinks, but the binaries are available, which is the important thing Jan 31 08:19:39 koen: yep, I can work with that ;). Thanks. Jan 31 09:24:25 is it possible to disable x11? i want only terminal to work Jan 31 09:25:11 maybe shipping the bone in a tin can was not such a good idea since users seem to assume they can just drop it inside and run it... Jan 31 09:49:13 i have a big problem... Yesterday i wrote "opkg upgrade" but today when i came it was not installed, instead somewhere at installation 'killed' was written. And now 'lsmod' result is nothing.. Jan 31 09:50:28 what can i do now? Jan 31 11:52:09 Where to set loading kernel module at startup? Jan 31 11:52:37 * etheretic wibbles muchly at http://radargadgets.com/index.htm (120€ AIS receiver) Jan 31 11:53:25 it probably runs on free energy, makes it cheaper Jan 31 11:54:03 mru: can't help youself, can you? :D Jan 31 11:54:22 more worryingly, can't seem to help you Jan 31 11:55:20 bother to put your preconceptions aside, investigate a bit on your own. go off the beaten path. Jan 31 11:57:00 the above means that the 1000$ goal for the LinCruiser (or whatever) is a notch closer to realism. Jan 31 11:57:21 I didn't know you cared about realism Jan 31 11:57:34 it's much easier to just believe Jan 31 11:57:41 indeed. Jan 31 11:58:40 the majority has never been right about anything fundamental throughout known history. ever. Jan 31 11:59:05 yes, scientists are sadly a minority Jan 31 11:59:29 * av500 reminds people that we have not yet reached friday Jan 31 11:59:32 seriously afflicted by groupthink. Jan 31 12:00:07 what use is that above gadget? Jan 31 12:00:26 * etheretic flagwaviums at av500 Jan 31 12:01:02 ah, there is one for ships too Jan 31 12:01:12 av500: I suppose it receives some messages broadcast by ships/planes Jan 31 12:01:13 aye. Jan 31 12:01:29 mru: yes, but why a gadget when there are websites that provide that.... Jan 31 12:02:12 websites are 1) not realtime, and 2) not accessible at sea Jan 31 12:02:33 mru: spot on. Jan 31 12:02:36 mru: yes, the ship one makes sense, but the plane one is useless Jan 31 12:02:51 av500: not for use in a plane Jan 31 12:03:01 its not like you stand a chance to run into a plane in your living room Jan 31 12:03:05 av500: i was referring to the marine gadget. Jan 31 12:03:07 if you're flying about in the sky it's nice to know what's around you Jan 31 12:04:09 I hope people flying around are not constantly looking at a laptop :)= Jan 31 12:05:08 bet it costs no more than 20€ from factory, if ordered in bulk. Jan 31 12:05:25 av500: it could sound an alarm if something is too close or on a collision course Jan 31 12:05:40 mru: the ship one, yes Jan 31 12:05:47 and why not the plane one? Jan 31 12:06:12 that's why planes send out those messages in the first place Jan 31 12:06:13 it can be interfaced with OpenCPN which runs on the Beagleboard. Jan 31 12:06:19 because it would scare me to know that people rely on this :) Jan 31 12:06:35 no sane pilot would _rely_ on it Jan 31 12:06:35 there is always ATC and sidewinders Jan 31 12:07:15 but as an added safety measure, it can't do any harm Jan 31 12:07:47 do you use a seat belt when driving? Jan 31 12:07:55 Where to set loading kernel module at startup? Jan 31 12:08:18 http://www.chartsandtides.co.uk/chartplotter/gpsdongle may be more relevant/specific. Jan 31 12:08:31 juhsis: in the configuration file your distro uses for that purpose Jan 31 12:08:49 i am asking for that file Jan 31 12:09:19 i use angstrom 3.0.14+ Jan 31 12:13:18 mru : ^ Jan 31 12:13:37 you're better off asking koen Jan 31 12:14:01 so koen : ^ Jan 31 12:21:02 i think koen is not here, anyone else know this? Jan 31 12:21:08 anyone know a clever way to find out what (uart, timer, pwron) was the source of a suspend wakeup? Jan 31 12:21:32 juhsis, write a script and place it under /etc/rc5.d Jan 31 12:21:51 I have a stupid way to find out if it was a timer :) Jan 31 12:21:55 the name should start with Sxx Jan 31 12:22:06 where xx is a number Jan 31 12:22:13 like s01? Jan 31 12:22:20 sorry S01 Jan 31 12:22:26 like S25myscript Jan 31 12:22:29 yeah Jan 31 12:22:57 isn't there already some startup script that loads a list of modules? Jan 31 12:22:58 the number defines the order of script execution Jan 31 12:23:11 so primitive Jan 31 12:23:35 ok sundar_ thx much Jan 31 12:23:56 as mru said, there is an easier way to do this Jan 31 12:24:09 probably /etc/modules ? Jan 31 12:24:16 depends on the rootfs you use Jan 31 12:24:28 3.0.14+ my kernel Jan 31 12:24:29 also on the init Jan 31 12:24:33 dig around /etc and see what you find Jan 31 12:24:39 init scripts* Jan 31 12:24:50 sundar_ doesnt work.. Jan 31 12:25:25 juhsis, which one Jan 31 12:25:35 i create "vi S01modprobe" under /etc/rc5.d Jan 31 12:25:46 and inside i write "modprobe g_ether" Jan 31 12:26:03 but it didnt load at startup Jan 31 12:27:00 for modprobe to work you need to the module dependencies Jan 31 12:27:42 ? Jan 31 12:28:21 you need execution permission for the file you created Jan 31 12:28:33 aah ok Jan 31 12:28:43 second you need module dependencies for modprobe to work correctly Jan 31 12:29:40 g_ether doesnt need any other module, as i know.. Jan 31 12:30:33 then use insmod its simple Jan 31 12:31:46 always use modprobe Jan 31 12:32:06 and just find the file with auto-loaded modules and add it Jan 31 12:32:12 there has to be one somewhere Jan 31 12:32:15 every distro has one Jan 31 12:32:16 sundar_ : when i write after startup ./S01modprobe Jan 31 12:32:31 it loads modules but still dont loads at startup Jan 31 12:33:01 mru : i am seeking for it nearly last 1 hour Jan 31 12:33:55 * ogra_ would just try creating /etc/modules and drop a line with "g_ether" in it Jan 31 12:33:58 wow, one hour Jan 31 12:34:07 that must be a record Jan 31 12:34:33 :) Jan 31 12:36:30 ogra_ doesnt work Jan 31 12:36:54 of course he does not work Jan 31 12:37:14 :) Jan 31 12:37:16 he just hangs out on irc like the rest of us Jan 31 12:37:18 lol Jan 31 12:38:37 av500 : do you know ? Jan 31 12:39:02 I would have suggested something like the above Jan 31 12:39:14 hmm, i always thought /etc/modules was an upstream default from module-init-tools (kerneltools.org) Jan 31 12:39:49 seems i'm either wrong or angstrom doesnt use module-init-tools Jan 31 12:40:08 juhsis: do you see other scripts in etc/rc.something? Jan 31 12:40:15 yes Jan 31 12:40:19 http://26-26-54.hardwarebug.org/19 Jan 31 12:40:22 so, add yours Jan 31 12:40:40 maybe you are no in runlevel 5... Jan 31 12:40:41 not Jan 31 12:40:42 juhsis, under which runlevel have you put your script Jan 31 12:40:43 i added Jan 31 12:40:54 5 Jan 31 12:41:09 how can i learn which level am i in? Jan 31 12:41:49 https://www.google.com/search?q=find+out+runlevel Jan 31 12:42:20 if you have the runlevel command, run it Jan 31 12:42:28 or see /etc/inittab Jan 31 12:42:38 but why are you messing with init scripts? Jan 31 12:42:42 ok it was 1 .. Jan 31 12:42:45 JUST ADD THE MODULE TO THE LIST Jan 31 12:42:54 runlevel 1 wtf? Jan 31 12:43:18 what you need is to know how to google rather than getting answers for thousand little trivial questions Jan 31 12:43:31 enjoy runlevels before lennart makes them go away.... Jan 31 12:43:51 or convince koen to use something sane :P Jan 31 12:43:53 av500 : i copy my script to rc1.d Jan 31 12:43:59 but still not works Jan 31 12:44:37 and it executable? Jan 31 12:44:40 you used the right format (with start and stop etc ? Jan 31 12:45:16 probably systemd ignores it if its not written in the right way Jan 31 12:45:30 ogra_: that would imply looking into one of the existing ones Jan 31 12:45:30 i used google : but in every webpage they said init modules is in "somewhere i dont have" and "somewhere doesnt works" Jan 31 12:45:49 av500 : yes it is Jan 31 12:45:54 av500, indeed, i was blantly assuming he had done that (or googled for the right format before) Jan 31 12:46:03 when i write "./S01modprobe" Jan 31 12:46:06 it loads Jan 31 12:46:34 cos it just executes your insmod command wriiten in Jan 31 12:47:39 juhsis: did or did you not compare it to existing scripts? Jan 31 12:47:40 i mean even though it loads with "./S01modprobe" it doesnt load at bootup.. Jan 31 12:47:42 like ogra_ said, you need start) case Jan 31 12:47:51 and if not, why not? Jan 31 12:48:34 paste your file Jan 31 12:49:40 av500 : they are long scripts.. Jan 31 12:50:36 modprobe g_ether Jan 31 13:59:59 anyone from Always Innovating here? Jan 31 14:00:15 sometimes Jan 31 14:03:39 sometimes innovating... Jan 31 14:06:27 always something? Jan 31 14:12:13 http://www.alwaysinnovating.com Jan 31 14:12:19 yes Jan 31 14:13:57 make their touchbook weatherproof, add a few features, and voila; the LInCruiser! :D Jan 31 14:14:40 will making it wetherproof also mean it wont fall on its lid all the time ? Jan 31 14:15:17 ogra_: if you add some inertial stabilisers, sure Jan 31 14:15:20 ogra_: depends on how many sheets of stainless steel you weld on Jan 31 14:15:40 mru, you mean beyond the taped in lead bars it already has ? Jan 31 14:15:41 and where Jan 31 14:16:12 (which loosen after a few weeks of usage) Jan 31 14:16:22 ogra_: not a problem - it'd be mounted on the cabin wall facing the cockpit. Jan 31 14:17:25 it will make the boat capsize then Jan 31 14:17:34 P Jan 31 14:17:36 heh, yeah Jan 31 14:18:37 though the lead bars are just attached with double sided tape, easy to remove Jan 31 14:18:47 these are mawkish comments. Jan 31 14:18:55 (or just use it for a week and they fall off on their own) Jan 31 14:19:12 (rattling around inside the case) Jan 31 14:19:16 etheretic: now you made me google Jan 31 14:19:33 ... Jan 31 14:21:17 ogra_: i'm speaking of possibly using the tb as a starting point. the result would have little in common with the vanilla tb. Jan 31 14:21:47 well, why not just use a proper tablet then ? Jan 31 14:22:11 thet're expensive and power hungry. Jan 31 14:22:16 y Jan 31 14:22:16 ? Jan 31 14:25:06 the capacity of a 120Ah boat battery is limited. Jan 31 14:26:26 product i'm thinking of is aimed at <30ft sailboats. Jan 31 14:26:53 etheretic: sailboats? Jan 31 14:27:11 dwery: aye. Jan 31 14:27:52 what are you going to place on a sailboat? Jan 31 14:28:14 primarily. can obviously be used aboard mb's too (power consumption is less of an issue). Jan 31 14:28:49 dwery: a low-cost Linux-based navigation system. Jan 31 14:29:43 low-cost=1000-1200€/$. Jan 31 14:30:33 that would be nice. how about the maps? Jan 31 14:30:40 obviouly, it can be used as a normal laptop/notebook too. Jan 31 14:33:22 etheretic: use an android tablet Jan 31 14:33:46 av500: they aren't watertight. Jan 31 14:33:59 wrap it in plastic Jan 31 14:34:01 and which ones are? Jan 31 14:34:31 so use the guts of an android tablet inside a watertight enclosure Jan 31 14:34:42 av500: the box i'm thinking of will (must) be. Jan 31 14:35:44 for it to be usable under harsh/wet/salty conditions. Jan 31 14:35:58 are you buying or building? Jan 31 14:36:01 no hacks. Jan 31 14:36:28 want to have it built so i can buy it. Jan 31 14:36:54 ah Jan 31 14:37:03 etheretic: if you need an nmea200 interface, drop me a note ;) Jan 31 14:37:53 there's a big market for such a product. 10000s of "nutshells" which'd love to have one. Jan 31 14:38:40 etheretic: how about the maps? Jan 31 14:39:24 dwery: they're open source. or you can buy them. sd card. Jan 31 14:39:37 etheretic: open source navigation maps? Jan 31 14:40:06 dwery: the box would certainly benefit from a NMEA port or two. Jan 31 14:40:36 etheretic: I just built a can bus cape for the beaglebone. nmea2000 is can based. Jan 31 14:41:36 dwery: yes - http://map.openseamap.org/map/index.php?lang=en Jan 31 14:43:02 etheretic: quite nice.. I guess they do not qualify as electronic charts as per law requirements, but it's a nice addition Jan 31 14:43:07 dwery: ah, you're still with towertech Jan 31 14:43:18 koen: yep Jan 31 14:43:37 dwery: I almost added a "PS: does Alessandro still work there?" to the mail I sent this morning Jan 31 14:44:06 * koen checks Jan 31 14:44:16 12:42, so s/morning/afternoon/ Jan 31 14:44:20 koen: the spam filter got your email Jan 31 14:44:21 :D Jan 31 14:44:23 dwery: they'll develop towards professional standards. Jan 31 14:45:19 dwery: should I resend it? Jan 31 14:45:21 koen: will get back to you later today with that email Jan 31 14:45:26 thanks! Jan 31 14:46:04 the spam filtered emails are checked as well Jan 31 14:46:12 unless they get rejected at smtp level Jan 31 14:48:15 etheretic: I'm downloading the ipad app :D Jan 31 14:48:30 yo bro. Jan 31 14:48:53 i've got navionics too, quite well made Jan 31 14:49:31 importance is that they're vector, imo. Jan 31 14:49:37 yes Jan 31 14:49:45 scaleable/editable. Jan 31 14:50:38 koen: the patch is based on v3.1-meta-ti-r2f+gitr1d84d8853fa30cf3db2571a5aec572accca4e29d Jan 31 14:54:40 etheretic: this one looks rugged: http://www.aceeca.com/products/product_overview.php/cPath/24/products_id/17 Jan 31 14:55:05 I worked with aceeca products for a while.. their palmos unit was pretty nice Jan 31 14:55:28 i got it from reading your website :) Jan 31 14:55:32 we are still on their partners page :D Jan 31 14:55:38 XD Jan 31 14:55:54 I like "...Palm OS® is the leading operating system for the handheld market, covering more than the 80% of sold devices..." Jan 31 14:56:06 a bit outdated, isn't it? :D Jan 31 14:56:10 on your website :) Jan 31 14:56:23 I'll drop a note to the webmaster Jan 31 14:56:40 if he has not retired :) Jan 31 14:56:56 years ago you could interface a lot of thins on the aceeca devices :( Jan 31 14:57:19 * av500 still has a stack of 7 PalmOS developer training DVDs... Jan 31 14:57:33 it was the only expandable palmos platform since the demise of the springboard based devices Jan 31 14:57:45 av500, sell them to HP then :) Jan 31 14:57:54 * av500 looks at the french Visor on his desk Jan 31 14:58:01 ogra_: yeah Jan 31 14:58:21 I think they still sell palmos based units, but I wonder what the market share is Jan 31 14:58:32 its screen is a bit on the small side for navs/general usage. Jan 31 14:58:35 access tried to sell us palm a few years back Jan 31 14:58:40 we politely declined Jan 31 14:59:03 not the whole "palm", just a license :) Jan 31 14:59:32 I believe there's android on their roadmap Jan 31 14:59:55 etheretic: http://www.engadget.com/2011/10/10/motorola-unveils-rugged-et1-android-tablet-for-enterprise-types/ Jan 31 14:59:56 face-palm Jan 31 15:00:19 http://www.engadget.com/2011/06/16/panasonic-unveils-android-toughbook-slate-for-q4-sledgehammer-s/ Jan 31 15:00:58 http://www.linuxfordevices.com/c/a/News/Raptor-ID-RapidOne-and-RapidPad/ Jan 31 15:01:35 etheretic: the app in in german :( Jan 31 15:02:01 pretty unusable on th eiphone with that overlay in the middle of the screen Jan 31 15:02:01 av500: its form factor is very close to what i'm thinking of. Jan 31 15:02:26 dwery: didn't ask u to dl anything. 8) Jan 31 15:02:44 :D Jan 31 15:02:55 just ranting Jan 31 15:03:44 "less than 1000$" sounds promising. but that's without built-in GPS/AIS. Jan 31 15:04:42 sp it will $1000+ Jan 31 15:04:44 so Jan 31 15:04:55 but motorola isn't very open-anything. Jan 31 15:07:09 * etheretic decides to like "Gorilla Glass" Jan 31 15:10:01 etheretic: so you want an open, NMEA, GPS, AIS and rugged tablet for <$1000 Jan 31 15:10:16 that sounds like a plan :D Jan 31 15:10:36 av500: if doable. Jan 31 15:11:20 av500: u forgot "low power demand" - that's crucial. Jan 31 15:14:24 etheretic: right Jan 31 15:15:04 av500: sound ambitious/impossible (at that price)? Jan 31 15:15:56 not impossible Jan 31 15:16:23 but i fear your will not make this happen by pure willpower.... Jan 31 15:17:13 the software is the lowest cost (0), the ruggedness ~+30-50% of what youd expect for a similar but non-rugged. Jan 31 15:17:41 av500: i know. count on the butterfly effect. :D Jan 31 15:18:50 why not use the emacs command? Jan 31 15:19:05 erk, out of coffee. must procure. bbl. Jan 31 15:19:25 NishanthMenon: no trolling Jan 31 15:19:35 av500, :) Jan 31 15:19:53 av500, after all the learnings about ohm's law... could'nt resist ;) Jan 31 15:24:49 koen: i have been trying to find how to load g_ether module at startup from this morning on... Do you know how? Jan 31 15:25:39 my kernel is 3.0.14+ Jan 31 15:26:50 parana: juhsis had the same issue... Jan 31 15:27:01 :) i am also juhsis Jan 31 15:27:39 my irc client switches names sometimes.. Jan 31 15:36:30 Is anyone here familiar with gst-openmax? Jan 31 15:40:28 av500 : is it everytime get much time to do something in angstrom or in beagleboard? or is it specific for me ?:) Jan 31 15:42:43 I can't say Jan 31 16:11:24 av500 : what is u-boot for? may be i should put it there.. Jan 31 16:11:41 put what there? Jan 31 16:13:04 g_ether Jan 31 16:27:25 koen : are you here? Jan 31 16:41:06 wherever you go, there you are. Jan 31 16:52:14 hi guys, anyone willing to offer some guidance on getting the mainline 3.2.2 kernel up and running on a beagle xm rev c using bitbake? I've got a basic familiarity with the tools and I suspect what I need to do is create a recipe for the 3.2.2 kernel but I'm not sure. **** BEGIN LOGGING AT Tue Jan 31 17:23:32 2012 Jan 31 17:49:38 cat /sys/devices/platform/omapdss/display0/timings Jan 31 17:49:38 74250,1280/110/220/40,720/5/20/5 Jan 31 17:49:39 I executed that command and I got those numbers. what does that mean?

Jan 31 17:50:22 is that the pixel clock? or something like that Jan 31 17:52:51 that looks like pixel clock in kHz Jan 31 17:53:58 oh thx i got those number on Angstrom's distro Jan 31 17:55:23 but when i try to do echo "74250,1280/110/220/40,720/5/20/5" > /sys/devices/platform/omapdss/display0/timings on ubuntu that pixel clock is only 7200 Jan 31 17:55:41 i mean that is the max value Jan 31 17:55:58 do you have any idea why? Jan 31 17:57:50 do you mean 72000? Jan 31 17:58:20 sry yes i do Jan 31 18:02:03 does your kernel have CONFIG_OMAP2_DSS_DSI set? Jan 31 18:04:32 Im using rcn-ee's distro Jan 31 18:05:01 I haven't memorised his configuration Jan 31 18:05:11 let me see Jan 31 18:06:09 yeap. ;) CONFIG_OMAP2_DSS_DSI=y Jan 31 18:06:32 then that's not it Jan 31 18:07:00 compare the various OMAP2_DSS options between the kernels Jan 31 18:07:05 hi rcn-ee Jan 31 18:08:01 hi tholm, care to test a patch, i don't have a montor that needs (so can't test it), it but this might fix it for you: http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/meta-texasinstruments/tree/recipes-kernel/linux/linux-3.0/beagle/0011-beagleboard-reinstate-usage-of-hi-speed-PLL-divider.patch Jan 31 18:08:40 what clock source does it use without that? Jan 31 18:09:23 i belive the slow very limited one.. Jan 31 18:10:04 rcn-ee: sry but i need to recompile the kernel? Jan 31 18:10:33 yeah. ;) but if you give me a few minutes, you'd just have to wait for the download. .;) Jan 31 18:11:02 oh many thx :-D Jan 31 18:11:44 not problem.. I've been eyeing the patch for a few days, as i know some monitor don't work with my kernel setup.. But all my monitors work, so i haven't been able to test it personally. ;) Jan 31 18:17:05 Hi rcn-ee Jan 31 18:17:24 hello Jan 31 18:17:25 I've been eyeing your repo on github Jan 31 18:17:46 fork away ;) Jan 31 18:17:58 the v4l guys have advised me I should start work from mainline on my camera driver for the beagle xm Jan 31 18:18:12 so I'm trying to get 3.2.2 built Jan 31 18:18:45 is it erroring out or? Jan 31 18:19:20 heh, it will be nice when I'm to the poit things are that simple. I'm still at the for, uh, lets see... "man git / fork" read read read stage Jan 31 18:20:12 oh, nothing of the sort, first things first I've got to create a recipe and gather the appropriate beaglexm patches Jan 31 18:20:54 right now, mainline is in pretty good shape for the xm, the biggest set of patchset i have, is just the expansion board stuff.. Jan 31 18:20:56 I was more just hoping to pick your brain to see if there were any specific patches you knew were critical in getting 3.2.2 up on the xm Jan 31 18:22:32 My understanding is that I still need to patch the board file to enable the vaux3 * 4 for the camera expansion header. Jan 31 18:23:58 so since there isn't a recipe at present I guess I should submit it when I write it? Jan 31 18:25:18 hi, can someone help me about how to compile code for beagleboard? I installed ubuntu on my beagleboard and i just want to write arm assembly code and run it Jan 31 18:26:02 my board version is C4 Jan 31 18:34:33 tholm, can you give the uImage/modules here a try: http://rcn-ee.homeip.net:81/testing/3.2-hi-speed-PLL/ (just rename the *.uImage as uImage in your boot and extract the modules to the rootfs) Ps, sorry it's a cable modem, so little slow.. Jan 31 18:35:23 dont worry ;-) thx Jan 31 18:35:52 spacecolonyone, is for that leapord board camera or a something else? Jan 31 18:42:05 rcn-ee: https://github.com/Angstrom-distribution/meta-ti/blob/master/recipes-kernel/linux/linux-3.0/beagle/0011-beagleboard-reinstate-usage-of-hi-speed-PLL-divider.patch ? Jan 31 18:42:26 * koen reads backlog Jan 31 18:42:48 koen, that's for a much faster pixel clock right? Jan 31 18:57:29 rcn-ee: this is for a built-from-scratch imager that is composed of a FPGA, a pair of 4 channel muxing 8bit ADCs and 8 Hamamatsu linear CMOS arrays. When you are building an astronomical spectrograph you wind up with rather custom needs ;). I'll be using the ccdc in raw 8-bit parallel grayscale cam_pclk will be 80MHz which means the cam_fclk needs to be >=160MHz, cam_mclk will probably be 80MHz. Jan 31 18:57:59 spacecolonyone, that sounds cool Jan 31 18:58:15 oh, it also has an i2c-2-parallel chip since the module has to be controlled over i2c Jan 31 18:59:47 Thanks, hellishly intimidating though. this is my first time mucking with linux in any serious fashion and my embedded experience is limited to avr-gcc! Jan 31 19:01:22 koen, would it be helpful for me to try and write my recipe for 3.2.2 i a nice, neat way with the intent of submitting it for inclusion in meta-ti?

Jan 31 19:02:51 oopd Jan 31 19:08:28 koen, so far i really like the musb drivers in v3.2-staging for the bone.. So far it's so much more solid swapping usb devices.. ;) Jan 31 19:09:04 rcn-ee: i used the new kernel and i didnt work. so I tried with 3.1.6-x6( original) and work again. Jan 31 19:09:41 same uEnv.txt on both boot Jan 31 19:10:07 humm very strange.. Jan 31 19:10:11 yep Jan 31 19:13:00 um I only see this difference omapfb omapfb: no driver for display: lcd <<<--- new kernel Jan 31 19:19:45 rcn-ee: yes, for the pixclock Jan 31 19:20:05 rcn-ee: I have 3.2 working on bone with the capes and adc Jan 31 19:20:16 rcn-ee: debugging PWM problems right now Jan 31 19:20:56 yeap, saw that this morning, and pulled in... I was having fun with the touchscreen changes last night.. ;) Jan 31 19:23:05 I think I'll remove the pwm stuff and then propose the update Jan 31 19:23:35 i'd say for the usb bus alone, it's well worth it... Jan 31 19:23:43 koen: what's the PWM for? Jan 31 19:24:00 ds2: backlight Jan 31 19:24:06 Oh that PWM Jan 31 19:24:18 thought you got the AM33x's PWM going Jan 31 19:24:20 PSP only hooked up ecap for backlight Jan 31 19:24:24 but CCO uses ehrpwm Jan 31 19:24:31 CCO? Jan 31 19:24:35 circuitco Jan 31 19:24:43 oh Jan 31 19:24:46 am33x has 2 kind of pwms, ecap and ehrpwm Jan 31 19:25:00 rcn-ee: work!!! Jan 31 19:25:00 they are not using the PMIC's backlight drive? Jan 31 19:25:06 no Jan 31 19:25:08 good job rcn-ee Jan 31 19:25:11 Oh Jan 31 19:25:16 that is F'ed Jan 31 19:25:22 i changed uEnv.txt Jan 31 19:25:23 tholm, it works? pixel clock much higher? Jan 31 19:25:30 yep Jan 31 19:25:37 with the new kernel Jan 31 19:25:45 hmmm Jan 31 19:25:54 looks like my design will have conflicts Jan 31 19:26:01 sweet, thanks for testing.! ;) Jan 31 19:26:02 oh well Jan 31 19:26:35 as long as the conflicts are well designed, it might be ok ;) Jan 31 19:26:38 dvimode="hd720 omapfb.vram=0:8M,1:4M,2:4M" Jan 31 19:26:47 that was the change Jan 31 19:30:21 no choice on the conflicts Jan 31 19:30:31 using up 95-99% of the resources Jan 31 19:31:37 rcn-ee: doesnt work the mouse and keyboard Jan 31 19:31:40 any idea? Jan 31 19:32:13 those should be hid modules in the modules tar file.. Jan 31 19:32:20 this might be a really stuid FAQ, but I got my 'bone rev A4 today, and eventhough I installed the drivers supplied on the sd-card I get two unknown devices called "BeagleBone" and no extra comport... anyone that care to bash me with a cluebat ? Jan 31 19:32:58 but i installed the modules Jan 31 19:33:04 Any ideas why the display with console-image and a BB-xM would quit working after running oebb.sh update? Jan 31 19:33:05 tholm, if the /lib/modules/3.2.2-x3.1/ directory is there, you can go thru serial and do "sudo depmod -a" to force it.. Jan 31 19:34:12 I was so thrilled to have the display just work when I built this past time using the angstrom setup scripts, now I update and it seems to have regressed Jan 31 19:34:28 rcn-ee: http://pastebin.com/yQsXZm4w Jan 31 19:36:09 tholm, ah, looks like the modules failed.. put the sd card back in your x86 "sudo tar xfv 3.2.2-x3.1-modules.tar.gz -C /media/rootfs/" Jan 31 19:36:31 ok Jan 31 19:43:33 fixed it Jan 31 19:43:47 sweet, good to hear.. Jan 31 19:44:18 thx for your help rcn-ee Jan 31 19:44:22 * emeb was highly amused to find out about the undocumented ARM9 in the OMAP3530 Jan 31 19:44:55 <_av500_> emeb: the 926? Jan 31 19:45:29 _av500_: not sure. Just heard that there's an ARM9 hanging off the C64 DSP that isn't in the TRM. Jan 31 19:45:49 <_av500_> yes Jan 31 19:45:54 etheretic: the sw is the lowest cost? sounds much like "I have a dream". Jan 31 19:46:06 I'm sure that's old news, but I'm usually late to the party. Jan 31 19:46:26 <_av500_> emeb: it used to be a so called "sequencer" for hd decode, something custom to drive the hw accels Jan 31 19:46:46 <_av500_> then it morphed into a 926 which was way easier to program Jan 31 19:46:51 _av500_: makes sense. Jan 31 19:47:02 it's a 968 Jan 31 19:47:11 <_av500_> you can do clever thigns with it, like color convert yuv while the dsp decodes the next frame Jan 31 19:47:16 aholler: you mean the eventual costs of hardware integration? Jan 31 19:47:16 * emeb wonders how long before the PRUs become Cortex M0s Jan 31 19:47:17 <_av500_> 968, yes Jan 31 19:47:31 etheretic: no Jan 31 19:47:38 emeb: there's already an m3 in the 33xx Jan 31 19:47:41 emeb: there was talk about replacing them with msp430 or m4 Jan 31 19:48:03 koen: heh Jan 31 19:48:04 emeb: iirc there isn't much difference in Si realestate between pru andm4 Jan 31 19:48:34 how can that be? Jan 31 19:48:37 koen: yoiks - the PRU must be fairly large then, or I'm overestimating the complexity of the M4 Jan 31 19:48:43 m4 seems a lot more complex Jan 31 19:48:55 <_av500_> its all tiny compared to the a8 Jan 31 19:49:01 of course Jan 31 19:49:04 heh Jan 31 19:49:09 the am33x m3 is funny Jan 31 19:49:17 it needs firmware for suspend/resume Jan 31 19:49:21 where is it? Jan 31 19:49:22 aka 60s delay in boot Jan 31 19:49:38 <_av500_> when we talked to a fabless silicon company to do our own chip they said we can put as many arm7 as we want ) Jan 31 19:49:39 etheretic: do you expect you can use some existing sw, run it on the beagle and it becomes automagically usable by a touchscreen? Jan 31 19:49:41 <_av500_> :) Jan 31 19:50:09 _av500_: I've heard from a fabless silicon company that if you license a9 you get as many arm7 as you want Jan 31 19:50:10 11 arm cores in a ti chip isn't special Jan 31 19:50:46 koen: someone told me that there are 7 in the OMAP44xx, of which only 5 are documented. Jan 31 19:50:47 aholler: depends. the company making it may already have the code. Jan 31 19:51:23 emeb: sounds about right Jan 31 19:52:12 koen: is the AM33xx M3 documented? Jan 31 19:54:40 derp - right in the TRM. How'd I miss that? Jan 31 19:55:54 rcn-ee: musb still dies if too much traffic. at least it looks so here (using 3.2.2). Jan 31 19:56:05 on a beagle classic Jan 31 19:56:30 aholler, fifo = 5? Jan 31 19:56:50 hmm, don't know about that Jan 31 19:56:58 dmesg | grep FIFO Jan 31 19:57:08 mom, have to turn on the thingy ;) Jan 31 19:58:50 rcn-ee: mode 4 Jan 31 19:58:51 aholler, laughs.. (can't reboot my panda es, cause i didn't connect it to my network power switch..) but next time, add this to the bootargs to force it " musb_hdrc.fifo_mode=5 " then you'll atleast be using the 8k of usb mem intead of 16k of which 8k doesn't work on the omap34x Jan 31 19:59:54 ah, ok, thanks. if it doesn't work, why isn't that set by default? stupid question, I know ;) Jan 31 20:01:40 last i check it is set in TI's psp stuff, but when last brought up for merge to mainline it didn't happen.. and up until, 3.2.x i forced it for all boards with my image.. (now if it's older beagle i just pass the bootarg) Jan 31 20:02:44 hmm, but that really that would explain why problems only occure when a lot traffic happens. Jan 31 20:03:27 back before we knew about it, i could only trigger it with file transfer greater then 2Gb.. Most of the time it just would work.. Jan 31 20:03:44 rcn-ee: thanks a lot, will se if it helps when I do emerge --sync the next time ;) Jan 31 20:04:26 up to know that was my case where it always failed Jan 31 20:04:42 or better, died ;) Jan 31 20:08:43 s/know/now/ ;) Jan 31 20:25:48 <_av500_> aholler: see what our kernel does Jan 31 20:26:02 rmed it ;) Jan 31 20:26:07 <_av500_> but that fifo thing sounds familiar Jan 31 20:30:06 I now have "mpurate=720 musb_hdrc.fifo_mode=5" in my uEnv.txt and it still boots and musb still works. so at least it doesn't do any harm ;) Jan 31 20:39:32 that was the last problem I had with musb I couldn't find a workaround for Jan 31 20:45:35 Hi. I tried to compile a simple hello world program using "gcc helloworld.c Jan 31 20:45:52 but got the error "bash: gcc: command not found Jan 31 20:46:08 gotta install the toolchain on bb if you are doing it there Jan 31 20:46:08 could someone help me? Jan 31 20:46:38 cc: ^^^^^ Jan 31 20:46:49 opkg install task-sdk-native or task-native-sdk Jan 31 20:47:03 someone should write that into a faq Jan 31 20:47:18 or the frontpage of beagleboard.org ;) Jan 31 20:47:19 assuming you did opkg update ... first Jan 31 20:47:44 and you don't us an image with root in ram Jan 31 20:48:02 aholler: these guys left me to google it iirc Jan 31 20:48:08 djlewis, aholler: thank you Jan 31 20:49:10 notice the toolchain name changes from time to time to keep us guessing ;) Jan 31 20:49:29 every friday I assume ;) Jan 31 20:50:39 was there some sort of regression with the default boot args in the past week or so? Jan 31 20:51:29 hey! we never digress but we drink :) Jan 31 20:51:34 I miss the time where regression were called bugs or problems ;) Jan 31 20:52:19 if the new stuff dont work, stay with the last known good ;) Jan 31 20:52:20 :) i miss having my display just work Jan 31 20:52:40 on a beagle? Jan 31 20:52:45 and that in an experimental world Jan 31 20:52:58 well, my git foo isn't up to snuff so I'm not sure how to roll back the changes oebb.sh update made Jan 31 20:53:07 yea beaglexM Jan 31 20:55:11 I was all excited that I didn't need to muck about creating a uEnv.txt last time I built with oe & angstrom then I update and BAM! no monitor for me! Jan 31 20:55:39 DSI PLL got fixed Jan 31 20:56:29 koen, you referring to this? Jan 31 21:00:21 koen: hm? what was that comment related to? (fixed an issue at work today where I couldn't get the pixelclk I wanted because I didn't use DSI PLL, so I'm curious) Jan 31 21:01:50 you have to use dsi pll to get arbitrary pixel clocks Jan 31 21:03:09 koen: what item got fixed? patch? Jan 31 21:03:54 just found time to try out my newly returned beaglebone, and network agine/still seems b0rked. if i start up the image that came with it and conenc tvia serial it falls into the avahi/zerocanf/whatever ip range. if i connect a usb ethernet adapter, it instantly works :/ Jan 31 21:04:42 well, atleast you get to connect to serial. mine seems to be borked and doesnt give me a comport. Jan 31 21:14:18 gerald doesnt return boards half loaded. check your stuff real good Jan 31 21:17:23 i didn't get my RMA'ed one back, i got a new one. the error is also not identical. on the RMAed one RC count on eth was stuck at 0, whereas this one at least seems to be partially alive. Jan 31 21:18:57 what i really don't get at the moment is why now again i receive nothing on serial again, thought the leds are blinking happily Jan 31 21:20:43 LetoThe2nd: it hates you, plain and simple..... Jan 31 21:21:24 prpplague: probably. Jan 31 21:21:56 prpplague: do you think it might be helpful to shout at it and give it names? Jan 31 21:21:57 LetoThe2nd: i think heard it say something about a phobia of worms Jan 31 21:22:00 LetoThe2nd: its trying to make you really earn its respect ;) Jan 31 21:22:46 djlewis: all it's going to earn is another night on my desk and several reboots. ;) Jan 31 21:23:32 prpplague: hope you at least checked the relevant parts with SPICE ;) Jan 31 21:23:40 HA Jan 31 21:24:38 koen: pssst Jan 31 21:24:51 koen: i am bringing a box of sharp pointy sticks Jan 31 21:24:59 * djlewis never hears of koen, mru, av500, prpplaque or ds2 complaining of non working beagle products Jan 31 21:25:08 hmmm Jan 31 21:25:23 gods be gods.. Jan 31 21:25:28 lol Jan 31 21:25:42 prpplague: sticks? where and when? ;) Jan 31 21:26:22 LetoThe2nd: https://events.linuxfoundation.org/events/embedded-linux-conference/kooi Jan 31 21:26:37 prpplague: charrcharr Jan 31 21:26:53 djlewis: only when i do the damage that results in non-working beagle products Jan 31 21:30:58 i slowly get the suspicion that it's just having issues with my 1GbE systme here. will leave it for tonight and bring a 100MbE switch tomorrow to verify. Jan 31 21:31:35 so laters, folks. Jan 31 21:31:43 LetoThe2nd: later Jan 31 21:58:25 does anyone know off-hand where angstrom is setting the default kernel command line args. My suspicion is they changed in this past commit and I just need to find it... Jan 31 21:58:40 which past commit? Jan 31 21:58:57 isn't it set buy u-boot anyway? Jan 31 22:02:36 I was on e68325e..28db5ce and updated to head Jan 31 22:03:13 I'm looking through the diff atm trying to figure out what relevant changed. Jan 31 22:03:37 well look at changes in u-boot Jan 31 22:04:34 would that be in meta-oe, meta-angstrom, or somewhere else? Jan 31 22:04:48 for beagle? Jan 31 22:04:56 yea, xm Jan 31 22:05:00 meta-texas-instruments I think Jan 31 22:06:18 * spacecolonyone looks Jan 31 22:08:59 I am sort of guessing :) Jan 31 22:09:28 there were some changes, so it isn't absurd... Jan 31 22:09:50 I'm just slow as im still learning git syntax Jan 31 22:14:43 hi there, why cpu frequency on BB-xm is just 8000? Jan 31 22:15:14 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies Jan 31 22:15:14 300000 600000 800000 Jan 31 22:15:30 did you set mpurate in uEnv.txt? Jan 31 22:15:30 i mean 800mhz Jan 31 22:15:35 yep Jan 31 22:15:40 1000 Jan 31 22:16:09 can you pastebin your uEnv.txt.... just in case? Jan 31 22:17:15 Pastebin.com is under heavy load right now :'( Jan 31 22:18:14 mpurate=1000 Jan 31 22:18:59 that may not be enough to get it into your bootargs, depending on how it's configured Jan 31 22:19:47 Kernel command line: console=ttyO2,115200n8 console=tty0 mpurate=1000 buddy=none buddy2=none camera=none vram=32M omapfb.mode=dvi:hd720 omapfb.vram=0:16M,1:4M,2:4M omapdss.def_disp=dvi root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait fixrtc Jan 31 22:20:12 ok, should work then Jan 31 22:20:24 but it doesnt work Jan 31 22:20:31 :( Jan 31 22:21:04 i only get 800MHZ Jan 31 22:21:17 weird Jan 31 22:21:29 which kernel/distro? Jan 31 22:21:42 rcn-ee's distro Jan 31 22:21:43 open the hood and pull that governor off the carb . . . Jan 31 22:21:50 haha Jan 31 22:22:34 yea that i was thinkin' Jan 31 22:23:00 I've heard of speed issues in ubuntu on the xM, but I don't follow that closely Jan 31 22:23:58 there's a ways to hardwire the speed with a uboot command, but I'd have to look it up Jan 31 22:25:31 "mpurate=1000" but i'll still lock up the board on boot.. there's still quite a few of patches need for a mostly mainline kernel.. Jan 31 22:26:46 no, you can do a register write and skip the governor... but if theres stability issues it wouldn't be a good idea Jan 31 22:27:44 rcn-ee: so that's a bug? Jan 31 22:28:43 thurbad: do you have any idea how can i disable that governor? Jan 31 22:29:50 tholm, it's a feature not in mainline yet.. to get 1ghz on the xm the voltage needs to be increased and monitored... patchset: http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/meta-texasinstruments/tree/recipes-kernel/linux/linux-3.0/pm-wip/voltdm Jan 31 22:30:10 koen: just answered your mail, sorry for the delay. Jan 31 22:31:10 rcn-ee: just wanted to say thanks for all the hard work you do with Ubuntu and the BB Jan 31 22:34:00 ok thx Jan 31 22:35:36 rcn-ee, when you say it isn't in mainline yet, you mean it hasn't propagated to any of Linus' repos yet, right (e.g. 3.2.2 stable) Jan 31 22:37:00 spacecolonyone, well technically, it's a "feature" so doesn't qualify as "fix" for a stable release.. But at the same point, small bits are slowly heading to a mainline.. (if you look closely, mainline still doesn't set the C4/C5 as 720mhz devices either.. ;) ) Jan 31 22:37:40 so then it would wait for 3.3? Jan 31 22:39:23 So where is the default command line defined? I've found CMDLINE defined in recipes for thinkgs like the n900 but I've yet to find it for the beagleboard. I've never been confident in my uEnv.txt and I'd like to figure out how to make this happen as part of my image build. Jan 31 22:39:37 I don't think it made v3.3-rc1... Hey koen, if your still around who's responsible/working on mainline-ing the SR 1.5 stuff (1ghz for the xm) Jan 31 22:50:15 rcn-ee: nobody Jan 31 22:50:41 awesome! ;) Jan 31 23:02:27 aholler: earlier u suggested installing task-native-sdk, I did (my internet is slow), now it says "cannot find -lgcc_s" when I "gcc helloworld.c" Jan 31 23:02:32 could u help me out? Jan 31 23:12:22 no, sorry, I don't use angstrom myself Jan 31 23:21:29 av500: that outdated section of the website has been removed, ty ;) Jan 31 23:25:09 would someone be so kind as to verify this is a sane beaglexM uEnv.txt: Jan 31 23:25:12 console="tty0 console=ttyO2,115200n8" Jan 31 23:25:12 mpurate=1000 Jan 31 23:25:12 camera=none Jan 31 23:25:12 vram=32M Jan 31 23:25:13 dvimode="1280x1024MR-32@60 omapfb.vram=0:8M,1:4M,2:4M" Jan 31 23:25:37 spacecolonyone: remove the " Jan 31 23:26:42 it appears to work as is Jan 31 23:26:59 so why ask? Jan 31 23:28:21 since I've never seen any (complete-ish) documentation on uEnv and there are such a wide variety of recommended settings I wanted to make sure I wasn't omitting anything critical Jan 31 23:28:46 for instance someone earlier had buddy=none and buddy2=none Jan 31 23:29:40 spacecolonyone, "buddy" is used for passing expansion board information from u-boot to the kernel.. Jan 31 23:30:22 thanks rcn-ee, I suspected as much. Jan 31 23:30:33 and though it is working , the monitor only comes up after boot, with the login prompt. In the past I had it coming up right away. Jan 31 23:30:45 spacecolonyone: iirc dvimode="1280x1024MR-32@60 should be max of 24 bit Jan 31 23:31:00 not sure if it matters ... Jan 31 23:31:14 I was basing it off of http://www.sakoman.com/OMAP/how-to-change-the-display-resolution.html Jan 31 23:31:40 I always use 16bit Jan 31 23:32:02 I'll be happy if I can just get the monitor to come up before it gets to the login prompt Jan 31 23:34:44 hrm, something isn't right. df is showing root to have 2.7G available. I'm using a 16GB microsd Jan 31 23:36:55 what does the MR in the modeline mean? Jan 31 23:37:00 correction 4GB sd card, nm Jan 31 23:37:29 what a fright! Jan 31 23:37:32 jay6981: it makes it incompatible with some monitors. I never understood why that is used everywhere Jan 31 23:38:55 something like premature optimazation and everyone copied it ;) Jan 31 23:39:02 this is bizarre, whenever I insert my sd card the first time the boot partition mounts as read only. eject -> reinsert -> now read/write Jan 31 23:39:44 aholler: cargo cult ftw :) Jan 31 23:40:27 should only eject and plug card into a OFF beagle Jan 31 23:40:50 I am. Jan 31 23:41:04 wait, I think I'm hitting the lock switch Jan 31 23:41:17 ok guys I think I should call it a day! Jan 31 23:44:46 ttyO2 is the serial port on the board and tty0 is the monitor, right? Jan 31 23:53:36 night guys Jan 31 23:54:17 aholler: M is for vesa compatible modes and R is for reduced blanking to account for the low pixclock on omap3 Jan 31 23:57:18 I know that ;) Feb 01 00:02:11 and that R is imho evil. Feb 01 00:02:54 jay6981: btw. it is explained in /usr/src/linux/drivers/video/modedb.c Feb 01 00:03:08 cool, thx for the code ref Feb 01 00:03:32 the code isn't of interest, the comments are ;) Feb 01 01:14:33 hmm, either I see something else or we have a red moon here ;) Feb 01 01:18:02 no moon at all here Feb 01 01:18:16 it's hanging very low here Feb 01 01:31:06 lol - RPI has to explain why they can't ship kits w/ BGAs & POP. Feb 01 01:33:15 tax? Feb 01 01:36:08 heh - how many n00bs out there can hand-assemble a BGA w/ POP? Feb 01 01:36:56 It'd be an RMA nightmare: "You mean you can't use a solder gun for this?" Feb 01 01:38:09 everyone with a fry pan can ;) Feb 01 01:38:32 yeah - throw a little bacon in and you can have breakfast too. Feb 01 01:39:50 emeb, please, only for rohs setups Feb 01 01:40:11 Russ: oops - sorry. Feb 01 01:40:31 wouldn't want anyone to get lead poisoning form their breakfast. Feb 01 01:40:39 s/form/from/ Feb 01 01:42:47 ust read an (german) article about that: http://www.heise.de/mach-flott/artikel/Loeten-in-der-Pizzapfanne-Kleiner-Nachschlag-1406642.html Feb 01 01:43:25 in short: possible and usable ;) Feb 01 01:47:19 * emeb has reflowed on a hotplate. Works OK Feb 01 01:47:35 still wouldn't want to try it with BGAs. Feb 01 01:47:46 emeb: for bga's and grilled cheese Feb 01 01:48:01 prpplague: yum! Feb 01 01:48:07 crunchy! Feb 01 01:48:26 gotta get your daily dose of lead some way Feb 01 01:48:39 "that which does not kill you..." Feb 01 01:48:59 not really valid for cumulative poisons though. Feb 01 01:49:48 but you don't need to care about a pension Feb 01 01:50:04 I knew there was an upside in there somewhere. Feb 01 01:51:28 pen what? what sion? Feb 01 01:53:16 I think that's something old people used to get. Feb 01 01:57:49 we just will get funny weather and a run out of resources of any kind ;) Feb 01 01:58:31 Ah the excitement of the grim meathook future. Mad Max here we come! Feb 01 01:58:47 waterworld Feb 01 01:59:51 and the earthquake in sf is missing too Feb 01 02:00:13 not to mention the exxchange of the poles Feb 01 02:01:18 at least it seems we don't get bored to death ;) Feb 01 02:06:10 Anyone happen to know which page on the Beaglebone manual describes the analog to digital converter a little bit further? I'm trying to figure out the resolution... Feb 01 02:06:48 I assume you have to look at the trm, not the srm Feb 01 02:07:40 hmm trm? Feb 01 02:07:47 havent seen that page Feb 01 02:07:55 is that for the proccessor it self? Feb 01 02:08:11 technical reference manual Feb 01 02:08:24 es, it describes the registers and such Feb 01 02:09:30 Where can I the link for the trm? Feb 01 02:10:07 Xenland: beagleboard.org has the trm download links Feb 01 02:10:25 thanx prpplague | you the man Feb 01 02:16:10 does trm stand for something or is that a fancy word? Feb 01 02:17:37 technical reference manual Feb 01 02:25:39 Well i can't find the trm but I know that the Analog signal will produce a value up to 4096 isn't that 16 bits? Feb 01 02:26:07 Xenland: how many bits does it take to express 4096? Feb 01 02:26:14 heh Feb 01 02:27:08 no, 12 Feb 01 02:27:08 * Xenland thinks.... Feb 01 02:27:38 64? Feb 01 02:27:42 log2(4096) != 16 Feb 01 02:28:03 Oh? log2() thats how you figure it out? lol i was doing sqaure roots LOL Feb 01 02:28:24 heh Feb 01 02:28:50 you might want to review some math :) Feb 01 02:29:07 well the easy way is 2^10 is 1k, 4 k takes 2 more bits Feb 01 02:29:24 I knew there was a reason why my college stuck me in math for a pre-req for computer science and electrical engineering Feb 01 02:29:44 but log2 will give the correct answer as well Feb 01 02:30:32 Xenland: hehe, don't get frustrated, you are asking questions that can be answered with a little research, but atleast you are asking.... Feb 01 02:31:00 I've already done the research, i don't mean to sound like i want you guys to do the work for me -- I only ask questions to verify not to be lazy :) Feb 01 02:31:20 I alreayd fried a beaglebone once so thats the last time i want to do that Feb 01 02:31:52 Xenland: yea, i am just saying you probably should look into bit math to get a little better idea of what you are dealing with Feb 01 02:33:45 Yeah i guess you guys/gals arn't my hired knowledged ninjas Feb 01 02:33:55 Xenland: hehe Feb 01 02:33:57 Xenland: not that Feb 01 02:34:03 Thanks for the plentiful information i appreciate it :D Feb 01 02:34:41 In your opnion whats the point of an IRC then if its not helping? Just curious, maybe i have the idea of an irc all wrong( or more specifically spark funs irc) Feb 01 02:34:53 lol #beagle Feb 01 02:34:55 (not spark fun) Feb 01 02:35:18 Xenland: just remember 8bits = 1byte = 256. add one bit and you have 256*2=512, add another = 1024, than 2048 than 4096 Feb 01 02:35:54 it's taht easy ;) Feb 01 02:36:04 irc is for helping, sure... but it doesn't replace searching on the web first Feb 01 02:36:51 See when you put it that way I can recall that 4096 is apart of that 1024 incrmental system.... Feb 01 02:37:15 so the answer to my question is that the Beaglebones adc is 4096bits? Feb 01 02:37:35 * prpplague bangs head on desk Feb 01 02:37:59 1k, 1M, 1G... etc are all 2 to some multiple of 10 Feb 01 02:38:25 I mean i've done all the reasearch i can, I've been studing the beaglebone for 2 months and wrote 3-4 tutorials, Its just little information like this that is confusing -- sorry for being annoying Feb 01 02:38:59 Xenland: the research is in binary math Feb 01 02:39:16 ahh! Feb 01 02:39:18 Xenland: if you intend to work with computing devices, you need to understand how data is represented inside the computer Feb 01 02:40:23 I already understand -- I just needed to know the resolution of the Beaglebones analog to digital converter scince its not in the SRM and there is no available trm that i can find Feb 01 02:41:09 Anyways thanks again, i think i got what i needed to allow audio inputs and outputs for the beaglebone Feb 01 02:52:09 Hey does anyone know if the beaglebone has a /etc/profile.d/ folder Feb 01 02:52:34 dastalegummybear: depends on if it is loading with a root filesystem that has one..... Feb 01 02:54:02 sorry i'm not going to lie i'm new with linux really. but i just want to lanch a python script and i want it to be after log in Feb 01 02:54:38 how can i go about doing it with the beagle bone, because with the xm i can just use the Gnome startup launcher Feb 01 02:55:28 hello Feb 01 02:55:38 hi Feb 01 02:57:49 dastalegummybear: people are doing other things while on irc, they will respond as they have time Feb 01 02:58:15 dastalegummybear: the /etc/profile.d is a directory than can be created as part of the root file system Feb 01 02:58:39 dastalegummybear: depending on how and who created your root file system will depend on if the directory exists **** ENDING LOGGING AT Wed Feb 01 02:59:57 2012
