**** BEGIN LOGGING AT Tue Jan 08 02:59:59 2013 Jan 08 03:00:35 of course casual dress can go too far Jan 08 03:00:55 if you wear flip flops to work i wish death on you :) Jan 08 03:01:57 I wear flip flops to my current job Jan 08 03:01:59 :P Jan 08 03:02:11 thurbad: die! Jan 08 03:02:58 technically teva... so not /quite/ flip flop... but still Jan 08 03:03:36 emeb_mac: wears pyjamas to his job Jan 08 03:03:59 nice Jan 08 03:04:48 mranostay: hehe, well my "casual" is a dress shirt and slacks Jan 08 03:05:11 at least i don't dress like a hipster Jan 08 03:05:25 suits one size too small? Jan 08 03:05:37 yeah that would be one thing Jan 08 03:05:46 porkpie hat Jan 08 03:05:52 lol Jan 08 03:05:55 i am at work in shorts and t-shirt today Jan 08 03:06:04 the guys down stairs are complaining Jan 08 03:06:14 that they have their overalls on Jan 08 03:06:29 what are you sheep farmers in your spare time? Jan 08 03:06:40 got any banjos? Jan 08 03:06:40 :) Jan 08 03:06:50 lol.. they are runnign the machines. and they ahve 7 fingers on each hand Jan 08 03:07:17 7 fingers would be handy for banjo playing Jan 08 03:07:43 finally a inbreeding defect that works out Jan 08 03:07:56 lol, you can type at 280wpm Jan 08 03:08:27 human polydactyls Jan 08 03:08:55 * emeb_mac has a polydactyl cat - good thing he's too dumb to know what to do with those thumbs. Jan 08 03:08:57 I don't think there is a 7 finger dvorak variant Jan 08 03:09:19 polydactyl cats tend to be smarter than average Jan 08 03:09:50 this one is just gifted at getting into trouble. Jan 08 03:09:50 apparently in your case that not a rule Jan 08 03:10:30 we say that when they were handing out brains, he got in line for more toes. Jan 08 03:10:45 heh Jan 08 03:45:32 oh boy stuffs from intelz Jan 08 03:47:16 whadja get? Jan 08 03:47:59 cardboard box! packing peanuts! pink bubble wrap! Jan 08 03:48:14 ssssh :) Jan 08 03:53:10 love the loan period section of this agreement Jan 08 03:53:22 aka never sell this thing Jan 08 03:53:28 awwww - you have to give it back Jan 08 03:54:34 only if they want it Jan 08 03:55:16 is this like those processor loans that they do for employees? got some buddies who work there who do that. Jan 08 04:16:33 which I doubt they will... Jan 08 04:16:47 when i get homze I'll will have to look if Santa brought me a pressie. Jan 08 04:17:18 fish river? Jan 08 04:18:56 2 Jan 08 04:19:55 fishy! Jan 08 04:21:16 kraken river is too scary Jan 08 04:22:04 wonder who goes to Android Builders Summit Jan 08 04:22:32 RELEASE THE FISHY! Jan 08 04:23:32 ds2, android builders! Jan 08 04:23:42 I'm just sayin' Jan 08 04:23:54 emeb_mac: +1 Jan 08 04:25:46 wonder if should send in a proposal just for the hell of it Jan 08 04:27:38 yeah it for my north lab :) Jan 08 04:36:42 why are many of the embedded linux kernels stuck at 2.6 and not something newer? Jan 08 04:36:54 hehe Jan 08 04:37:07 yates: there are many reasons Jan 08 04:37:14 yates: but some of the top ones are Jan 08 04:37:36 yates: not enough employee resources to update a hardware platforms kernel to a newer verson Jan 08 04:38:02 yates: newer kernels can introduce sutle new bugs which are bad for a commercial product Jan 08 04:38:32 prpplague: well, can't you just grab the kernel source and have at it yourself? i.e., configure and recompile? Jan 08 04:38:38 yates: companies don't push their device supprot into mainline so it makes it very difficult port their hacks forward to new kernels Jan 08 04:38:57 yates: only if the company has pushed the support mainline which most don't Jan 08 04:39:30 what companies are you referring to? the cpu vendor? board mfr? Jan 08 04:39:47 yates: all of the above Jan 08 04:39:56 yates: they build on the failure Jan 08 04:40:17 yates: it is a long debated topic Jan 08 04:40:27 hum.. Jan 08 04:40:44 HE HE HE HE HE HE HE Jan 08 04:41:05 prpplague: thanks for the education Jan 08 04:41:19 never heard this topic before Jan 08 04:42:00 hehe Jan 08 04:42:05 what kernel does the beagle-xm support? Jan 08 04:42:19 hohohahaheehee Jan 08 04:42:23 * prpplague wanders off to read a data structure book Jan 08 04:42:36 must be trying to go to sleep Jan 08 04:43:04 prpplague: just read K&R again instead Jan 08 04:43:39 prpplague: try Knuth's "Art" Jan 08 04:44:10 * mdp abandons dmaengine until tomorrow Jan 08 04:44:12 bbt Jan 08 04:45:46 any job that requires you to read a data structure book ain't worth working for Jan 08 04:46:06 let's focus on reality... circuit analysis, phasors, etc Jan 08 04:46:20 phasors? you been watching too much star trek. Jan 08 04:46:36 does the beagleboard use the arm cortex A8? Jan 08 04:46:38 mdp: abandon all hope ye that enter Jan 08 04:46:45 (true quote from one of my dynamics profs in college) Jan 08 04:48:06 if so, why do the instructions for the beagleboard here refer to "linux-omap" - that's like the 4460 from TI, right? Jan 08 04:48:12 http://elinux.org/BeagleBoard#Linux_kernel Jan 08 04:48:49 emeb_mac: whatever you spell that... the complex exponential stuff Jan 08 04:49:10 Euler's theorem Jan 08 04:49:28 ds2: I know exactly what you mean, but that ME prof didn't. Jan 08 04:49:53 oh okay Jan 08 04:49:59 :) Jan 08 04:50:11 ME's have their own quirks Jan 08 04:50:11 ask Cauchy and Riemann. Jan 08 04:51:02 if so, why do the instructions for the beagleboard here refer to "linux-omap" - that's like the 4460 from TI, right? Jan 08 04:51:19 is there an echo in here? :) Jan 08 04:51:36 the ECAN is broken Jan 08 04:52:03 emeb_mac: i was hoping to find an answer. Jan 08 04:52:37 the panda was based on omap but not beagle, unless that was an earlier version. right? Jan 08 04:52:59 yates: the original beagleboard used an OMAP3530 processor Jan 08 04:53:20 ah. Jan 08 04:53:32 the DM35xx used on the Beagleboard XM is closely related, even though it's not officially an OMAP. Jan 08 04:53:51 kissing cousins? Jan 08 04:54:04 dm37XX Jan 08 04:54:10 derp Jan 08 04:54:20 there is an am35xx part though ;) Jan 08 04:55:05 the am35xx are very similar to the am33xx Jan 08 04:55:49 200 different Jan 08 04:57:11 the rev3 schematics call it an "OMAP3730" Jan 08 04:57:46 talk to your friendly local TI rep Jan 08 04:59:14 i was confyoosed - sorry Jan 08 04:59:39 tongiths effort will be to try to get the TI ICE to fire up Jan 08 04:59:48 the 3730 IS an ARM Cortex A8... Jan 08 05:00:38 i'm seeing the acronym "OE" in some of the kernel stuff - what is that? Jan 08 05:01:03 mrpackethead_: in-circuit-emulator? Jan 08 05:01:20 Industrial Communications Engine Jan 08 05:01:20 wouldn't firing an ice melt it? Jan 08 05:01:28 its like a beagle but different Jan 08 05:01:46 OE is the Obfuscation Engine Jan 08 05:02:24 eschew obfuscation Jan 08 05:03:11 ds2: were you serious? Jan 08 05:06:02 oh yeah, the DM37x has the ARM plus the TMS320C64x+ core. Jan 08 05:07:13 the AM-series don't have the 64x Jan 08 05:09:14 the AM3359 is a very useful device Jan 08 05:09:22 when you get your head around the PRUSS Jan 08 05:11:12 PRUSS: sounds architecturely similar to the CLA on the TMS320F28x Jan 08 05:15:12 i should say, functionally similar Jan 08 05:15:42 mrpackethead_: what did you use pruss for? Jan 08 05:15:55 i have two projects Jan 08 05:16:00 i'm usin it for Jan 08 05:17:07 for example? Jan 08 05:17:44 to handle data xfers between the arm and dsp? Jan 08 05:18:55 for doign stuff. Jan 08 05:20:46 oh, well you da' man Jan 08 05:20:55 i can't talk about the 2 projects Jan 08 05:21:06 but there are some good examples Jan 08 05:23:25 can you run you own custom 64+ code on the DM37x? Jan 08 05:31:14 of course Jan 08 05:48:14 * mranostay opens his nixie tube package Jan 08 05:49:29 A NEW PACKAGE! Jan 08 05:49:46 mranostay gets a lot of late deliveries Jan 08 05:50:32 that is a late late Jan 08 05:52:52 emeb_mac: he shops under bridges Jan 08 05:53:14 ds2: you can find some good stuff there. Jan 08 05:53:42 mranostay, pics or it didn't happen Jan 08 05:53:45 yes, but they can get rather 'warm' Jan 08 05:53:50 ™ Jan 08 06:13:37 guess I better head home...otherwise I'll never know if I have a toy. Jan 08 06:23:07 ka6sox: getting a late delivery of nixie tubes? Jan 08 06:28:24 fish I think Jan 08 06:29:24 ooo Jan 08 06:30:16 http://www.youtube.com/watch?v=_7VgDSNxlGU Jan 08 06:31:51 Russ: ok vfd tube stuffs Jan 08 06:36:25 ka6sox: FRI2? :) Jan 08 06:40:00 yes, a fish FRi2 Jan 08 06:40:14 (beer batter is the best) Jan 08 06:43:08 dammit "# CONFIG_USB_SERIAL_TI is not set" Jan 08 06:43:33 koen: *ahem* :) Jan 08 06:47:13 well this thing is as warm i would expect an x86 system Jan 08 06:47:36 oh.. so that means you can cook eggs on it? Jan 08 06:47:49 make donuts. Jan 08 06:48:10 or maybe even melt steel on it? ;) Jan 08 06:48:16 foot warmer Jan 08 06:58:33 you having special character in my SSID was probably a bad idea Jan 08 07:02:39 wtf does this mean "cfg80211: Calling CRDA to update world regulatory domain" ? Jan 08 07:03:40 stay right where you are - the MIB has been dispatched to your location. Jan 08 07:10:35 good morning boys Jan 08 07:11:36 who you calling boy? Jan 08 07:11:39 mranostay: wlan cards use different frequecies and are allowed different tx powers depending on which country they are used in Jan 08 07:12:08 ah yeah Jan 08 07:12:09 mranostay: at init, the kernel calls some user space program to load the necessary tables Jan 08 07:12:40 well the FCC isn't at my front door yet Jan 08 07:13:01 usually nobody will find out if you are using wrong settings Jan 08 07:13:04 usually.. Jan 08 07:13:41 blech grub Jan 08 07:17:42 mranostay, did you pass? Jan 08 07:20:15 yeah about that.. had some other fun that night and didn't wake up in time :) Jan 08 07:20:28 next weekend maybe :) Jan 08 07:21:01 * ka6sox wires up mranostay's phone friday night to shock him saturday in time... :P Jan 08 07:21:27 missed an exam? Jan 08 07:21:43 15 demerits Jan 08 07:24:17 opposite sex comes over any silly ham radio test :) Jan 08 07:24:34 there will always be another exam for instance Jan 08 07:26:56 there will always be another girl too ;-) Jan 08 07:27:55 and ofc, if you are gay, the opposite sex doesn't really matter ;-> Jan 08 07:28:26 * mranostay smacks KotH Jan 08 07:37:37 mranostay: are you a ham yet? Jan 08 07:37:52 oh n/m Jan 08 07:39:26 ds2, just call him "sleeping beauty" Jan 08 07:39:48 * mranostay curses wpa_supplicant Jan 08 07:41:35 hi there, I need to get notified when the framebuffer/display blanks in a userspace application. What is the interface for this? I need something like FB_EVENT_BLANK but for userspace... Jan 08 07:42:16 you asked this already Jan 08 07:42:29 yes, and the answer was: use FB_EVENT_BLANK Jan 08 07:43:11 but I now realized that in linux/fb.h there is a #ifdef __KERNEL__, so I can't use this event in userspace Jan 08 07:46:15 STOP DOING CRAP IN USERLAND Jan 08 07:46:22 this is stupid Jan 08 07:46:39 why? Jan 08 07:46:43 sp00k: what do you want to do? Jan 08 07:47:44 do you also try to drive to work with a legos car? Jan 08 07:49:11 I have a app that streams from a mt9p031 cam and relies on omapdss (and the whole omap3isp). While streaming the user can suspend the device or the console can get blanked, so I need to turn off streaming Jan 08 07:49:15 doing FB in userland is like BitBanging Video :P Jan 08 07:50:13 sp00k: why would you want to stop streaming when the console is blanked? Jan 08 07:50:28 someone say bitbanging? Jan 08 07:51:28 mranostay: move along, you're not a ham yet Jan 08 07:51:47 KotH: "echo 1 > /sys/class/graphics/fb0/blank" disables also the display and crashes the omap3isp when a streaming is going on Jan 08 07:55:27 KotH: yeah well i may be a nerd but i'm not a dork : Jan 08 07:55:28 :) Jan 08 07:57:06 prpplague: ping-ish Jan 08 07:58:50 how to use optional JTAG in beaglebone RevA5 ? do need to anything to switch the JTAG connection from FTDI to optional JTAG ? Jan 08 07:58:51 sp00k: then fix the crash Jan 08 07:59:08 chainz: how are your soldering skills? Jan 08 07:59:12 sp00k: on unix, applications are supposed to continue running as if nothing happend, if the display is blanked Jan 08 08:00:01 the optional jtag requires some rework that will totally void the warranty :) Jan 08 08:00:12 well one board I got RMA'ed with it on Jan 08 08:00:18 mranostay, are you trying to wake up those who *should* be in bed. Jan 08 08:00:23 KotH: jup, the app keeps running, but the omap3isp kernel module crashes ;) Jan 08 08:01:17 KotH: so I have to look if it is supposed to crash or of it is really a bug Jan 08 08:01:42 sp00k: the answer is simple: nothing is ever supposed to crash Jan 08 08:01:53 sp00k: unless it's an airplane Jan 08 08:02:01 ka6sox: isn't this like really late for you? :) Jan 08 08:02:42 boo. Jan 08 08:05:46 mranostay, ya, us OLD folks should have shuffled off to bed about dark right? Jan 08 08:06:11 <_av500_> right Jan 08 08:06:44 old folks from germany are taking over Jan 08 08:06:56 hey! Jan 08 08:06:59 i'm not german! Jan 08 08:07:09 * ka6sox hands the Torch to av500 Jan 08 08:07:14 KotH: you are what? 30? Jan 08 08:07:26 that's a horrible insult for any non-german! Jan 08 08:07:52 mranostay: we had that a couple of weeks ago already Jan 08 08:08:14 i have a short memory Jan 08 08:08:54 onset of dementia? Jan 08 08:09:04 Thanks for your replies. Jan 08 08:09:17 its working nice for me now Jan 08 08:09:17 chainz: you are welcome Jan 08 08:09:52 anyone past 30 is old to me anyway Jan 08 08:10:18 @koth : but its difficult to do Jan 08 08:10:30 _av500_: how is it rocking in the FRA? Jan 08 08:10:50 ka6sox: shouldn't u old folks be getting ready for the buffet lunch at 8AM? Jan 08 08:11:45 9am Jan 08 08:12:27 seems QEI cape has overrun everyone Jan 08 08:16:52 <_av500_> mranostay: in the .fr now :) Jan 08 08:17:12 _av500_: for fun? Jan 08 08:17:23 <_av500_> well Jan 08 08:19:50 _av500_: admitt it! you just want to meet j-b! Jan 08 08:21:00 why would anyone go to France? :) Jan 08 08:24:51 right panto? Jan 08 08:25:05 good morning Jan 08 08:25:15 what ever you say mranostay I support the opposite Jan 08 08:26:24 panto: that isn't completely true :) Jan 08 08:26:50 rarely Jan 08 08:32:32 they have nice cheese in france Jan 08 08:32:58 but the french people :) Jan 08 08:33:24 which cape is winning. Jan 08 08:33:33 well they have to judge it Jan 08 08:33:47 i noticed i forgot to upload BOM file today Jan 08 08:34:14 mranostay: you are the weakest link. Jan 08 08:34:19 BUZZZ! Jan 08 08:34:31 you have been voted off the island. Jan 08 08:34:49 yeah well i uploaded it pretty easily Jan 08 08:36:28 hpefuly they missed it Jan 08 08:36:30 :-) Jan 08 08:37:03 who's side are you on? :) Jan 08 08:37:18 the french Jan 08 08:38:45 im pretty pleased with my two days of solid beagle effort Jan 08 08:40:00 i've got a pair of beagles converting time into Linear Time code Jan 08 08:40:12 and then decoding them over a UHF radio link. Jan 08 08:42:18 cool i think Jan 08 08:51:07 i know its just moving code over from well know librarys Jan 08 08:51:19 but there was a cople of gotchas with the the arm stuff Jan 08 08:51:29 but the librarys are mostly all good Jan 08 08:51:37 good help from some smart people Jan 08 08:54:21 mranostay: hopefully you do that at a ns precision Jan 08 08:59:57 KotH: eh? Jan 08 09:00:05 * mranostay should sleep Jan 08 09:04:59 er... yes.. Jan 08 09:05:03 mranostay: you've to wrong nick! Jan 08 09:05:12 mrpackethead_: hopefully you do that at a ns precision Jan 08 09:05:39 no need to do it to ns precison Jan 08 09:05:41 * mranostay zzzzzzz's Jan 08 09:05:57 for this applicaiton 1ms is sufficent Jan 08 09:06:45 i would need to measure things but i suspect the precison is about sub 100us Jan 08 09:06:58 mranostay: sleep well! Jan 08 09:07:09 mrpackethead_: 1ms isnt fun! Jan 08 09:07:21 mrpackethead_: even dcf77 can do that Jan 08 09:07:53 mrpackethead_: with a bit of fiddling <100us is even possible Jan 08 09:08:01 with uhf you should be able to do <1us Jan 08 09:08:10 yup. Jan 08 09:08:17 but as i said, its not required for this Jan 08 09:08:28 must be a boring project then ;) Jan 08 09:08:46 no in fact its very interesting Jan 08 09:09:06 what are you doing? Jan 08 09:09:28 but since there are considerably larger system variances, +/- 5ms would'nt matter Jan 08 09:09:54 show control Jan 08 09:10:04 show control? Jan 08 09:10:27 lights, audio, pyro, mechanicals Jan 08 09:10:43 ah! Jan 08 09:10:56 well.. yes.. then ms precision is enough Jan 08 09:10:58 how can pryo not be ifun. Jan 08 09:11:10 *boooom* is always fun :) Jan 08 09:11:13 the pryo launch system is pnematic Jan 08 09:11:23 air cannon launches the shells Jan 08 09:11:59 a few lb/in differnece in pressure will result in a bigger differnce than a 2ms time variance. Jan 08 09:12:27 the signal on the UHF is low bandwidth audio Jan 08 09:12:31 its a very old protocol Jan 08 09:12:32 lb/in ^^' Jan 08 09:12:51 but is widely used show control Jan 08 09:12:58 .o0(when will people learn not to use their feet for measuring but walking) Jan 08 09:13:11 i can also work in kPa Jan 08 09:13:34 but most here seem to be of the imperial genre Jan 08 09:13:57 * KotH plays the imperial march Jan 08 09:14:09 are you in china? Jan 08 09:14:23 ^^' Jan 08 09:14:26 no.. switzerland. Jan 08 09:15:35 es ist alles Metrik in der Schweiz Jan 08 09:15:51 s/M/m/ Jan 08 09:15:55 s/ik/isch/ Jan 08 09:16:18 在瑞士,它的所有指标 Jan 08 09:16:21 that will fix you Jan 08 09:17:08 sorry, i dont read chinese... japanese would be ok though Jan 08 09:17:20 sorry i dont' do japanese Jan 08 09:17:24 and i only do chinese poorly Jan 08 09:17:45 my japanese isn't better, probably Jan 08 09:18:03 im actually quite blown away by these beagles Jan 08 09:18:04 i've barely spoken a word in years Jan 08 09:18:32 mrpackethead_ how so Jan 08 09:18:33 highly capable bits of kit! Jan 08 09:18:45 well, maybe not so much teh beagle itself Jan 08 09:19:09 but the AM3359 packs a lot of stuff into a small package Jan 08 09:19:46 juup Jan 08 09:19:52 modern SoCs are cool! Jan 08 09:19:58 yes. Jan 08 09:20:18 KotH i love modern SBC's Jan 08 09:20:20 but they are so complicated that you have to learn how to use them Jan 08 09:20:29 * KotH liked the integrated dc/dc power supply, complete with li-ion charger in the i.mx23... but its documentation sucks Jan 08 09:20:32 which is a tall task for people used to the old ways Jan 08 09:20:48 many will shoot me, but beig able to run debian ( which i'm familar with ) on it made a big starting point Jan 08 09:20:51 panto: well.. how old? Jan 08 09:21:01 panto: i grew up with hc11 and pic16c54 Jan 08 09:21:13 KotH, I caught the tail end of 68HC05 Jan 08 09:21:24 some people are still stuck there Jan 08 09:21:36 i'm suspecting that our PIC days might be numbered Jan 08 09:21:37 well, maybe got to pics or avrs Jan 08 09:21:39 mrpackethead_: why shoot you? it's better than running ubunto or even worse android Jan 08 09:22:00 mrpackethead_: pic is still going strong, especially in the low end, ultra low power segment Jan 08 09:22:21 mrpackethead_: and they are trying to get into the 32bit, arm7-class segment as well Jan 08 09:22:26 yup, my compnay used more than 100k PICs last year Jan 08 09:22:30 KotH, yes, but, the cortex M0s are coming Jan 08 09:23:01 but when you line up a PIC32 vs an ARM-8.. Jan 08 09:23:02 almost same power envelope, and much better s/w support Jan 08 09:23:27 panto: but more expensive :) Jan 08 09:23:41 for the styff we are involved with a few watts does'tn feature! Jan 08 09:23:46 KotH, silicon is stupid cheap nowadays Jan 08 09:23:55 it's the s/w costs that kill you Jan 08 09:23:55 our systems generally require 100's of kW's Jan 08 09:24:16 i do not worry about saving .5W on a processor Jan 08 09:24:31 when i am controlling 25kW pumps Jan 08 09:24:45 panto: not cheap enough Jan 08 09:24:49 right, and I bet that's what most people use embedded parts Jan 08 09:24:57 KotH, give it time Jan 08 09:25:07 panto: i've done projects, where the decision which chip to use was based on a 0.01chf difference of price Jan 08 09:25:09 we are not all buildign phones. Jan 08 09:25:25 KotH, that's a bad project to do then Jan 08 09:25:31 panto: no Jan 08 09:25:34 panto: high volume Jan 08 09:25:36 if you build enough of something then that is a valid decison Jan 08 09:25:50 how long did the decision take Jan 08 09:25:51 panto: several 10k units produced... per month Jan 08 09:25:56 KotH, for that kind of price difference you better sell millions Jan 08 09:26:02 yup Jan 08 09:26:18 and I still posit that's a bad decision that will hurt you down the road Jan 08 09:26:35 the impact of a single part change probably is a day of engineering time if you are lucky Jan 08 09:26:45 lets say thats 800 sFr Jan 08 09:26:52 you will sell for a couple of years, and then a competitor will come using an updated SoC Jan 08 09:26:54 at 0.01 Jan 08 09:26:59 panto: the first version of it peaked at iirc 200k/month.. then they did a redesign to use an asic to get the price even lower Jan 08 09:27:21 KotH, well, that's a clever decision Jan 08 09:27:36 thats 800,000 uniyd Jan 08 09:27:37 panto: the decision wasnt bad Jan 08 09:27:40 but I bet the application was a pretty simple one Jan 08 09:27:50 not huge gobs of s/w Jan 08 09:28:07 panto: iirc in the first year it already paid for a couple of weeks of development time Jan 08 09:28:22 i'm glad i dont' build massive scale electronics Jan 08 09:28:24 KotH, right Jan 08 09:28:29 ie large runs Jan 08 09:28:42 we build 1000's of stuff, not 1,000,0000's Jan 08 09:28:49 mrpackethead_: same here.. our usual volume is <100 .. in total ^^' Jan 08 09:29:04 but throw in something with a large software base, and the porting from a small constrained part will hurt you Jan 08 09:29:09 our latest project has a volume of 1 :-) Jan 08 09:29:33 hehe Jan 08 09:29:42 what kind o things do you build Jan 08 09:29:54 anything that is unusual Jan 08 09:29:55 :) Jan 08 09:30:29 I would like you to build a robotic octopus to use against by enemies in my underground lair Jan 08 09:30:35 is that unusual enough? Jan 08 09:30:44 <_av500_> no Jan 08 09:30:49 <_av500_> thats so 2010 Jan 08 09:30:55 from medical implants, over harsh environment electronics (high temp variations, high acceleration >10k g,..) to computer systems and space stuff Jan 08 09:31:08 <_av500_> space isa harsh mistress Jan 08 09:31:48 _av500_: we're currently in discussion with a guy who wants to build a deep space probe Jan 08 09:31:56 _av500_: that's fucking harsh ^^' Jan 08 09:33:00 * panto has done some ESA work Jan 08 09:33:09 KotH, what's the name of the guy? Jan 08 09:33:17 maybe you can build a probe to measure the price of eggs in mansrtrays residence Jan 08 09:33:18 sorry, confidential Jan 08 09:33:35 mr obama Jan 08 09:33:52 all our real projects are confidential Jan 08 09:34:14 our pretend ones are just bait to keep our competition guessing Jan 08 09:34:37 <_av500_> KotH: is deep space more harsh than shallow space? Jan 08 09:35:40 _av500_: as long as you are around earth, you have some protection from the remaining atmosphere and magnetic field Jan 08 09:35:56 <_av500_> right Jan 08 09:36:10 by the time its getting close to the target you are sending it to, you'll be dead Jan 08 09:36:15 so theres no need to worry Jan 08 09:36:16 :-) Jan 08 09:39:43 mrpackethead_: you dont have to believe anything i write... we are on irc after all Jan 08 09:39:58 mrpackethead_: but there are people here who know what kind of projects i usually do :) Jan 08 09:45:09 my stuff doe'snt ahve to survive space Jan 08 09:45:17 it just has to survive stage hands Jan 08 09:45:24 and lampies Jan 08 09:45:42 they are a fate possibly worse that the monsters in deep space Jan 08 09:45:44 lampies? Jan 08 09:45:59 a lampie is a lighting tech Jan 08 09:46:02 yeah.. i know how backstage looks like Jan 08 09:46:25 not that we use many (any) lamps now Jan 08 09:46:28 its all LED Jan 08 10:03:24 mrpackethead_: doesnt that give a very different light? Jan 08 10:03:39 and make things look odd... Jan 08 10:03:49 light is light Jan 08 10:03:57 you just need to learn to use it Jan 08 10:03:59 but spectrum is different Jan 08 10:04:09 is it? Jan 08 10:04:18 yes, very different Jan 08 10:04:18 yes, its diferent Jan 08 10:04:23 not that differnt Jan 08 10:04:49 but its time to go to bed Jan 08 10:04:55 sleep well Jan 08 10:05:12 Hi, I'm selling my board at the groups. If anyone's interested, please contact me. Jan 08 11:29:46 as we've just talked about e-papers: http://www.theregister.co.uk/2013/01/07/papertab_flexible_monitor/ Jan 08 11:32:15 tech is getting closer to the real paper thing Jan 08 11:41:40 but as the title of one of those pictures already said, get rid of the cables, please. ;) Jan 08 11:41:57 what about their batteries? Jan 08 11:44:30 I have a question about a BeagleBone with the latest ubuntu. What config is needed to connect the board through USB. Jan 08 11:44:55 My host computer is an Ubuntu 12.10 LapTop. Jan 08 11:48:01 what do you mean connect? get a usb console? Jan 08 11:52:31 usbnet? Jan 08 11:53:02 I mean an IP connection. The Ethernet connection works, but it must be configured through DHCP. Jan 08 11:53:28 I would like a static IP connection to may PC over USB, if possible? Jan 08 11:54:07 I vaguely recall various hotplug incantations on older ubuntus to live with netmanager, but dunno on newish ones Jan 08 11:54:33 killall -9 NetworkManager Jan 08 11:54:43 aholler_: now, if they would bind a hundred of them to a book, that would be a form factor i would imediatly buy :) Jan 08 11:55:42 mdp: last time i tryed to get networkmanager to use a fixed ip (about a year ago) i failed miserably Jan 08 11:56:10 joakimo: thats basic networking setup. you have linux on both sides, so just read a book or tutorial about setting up network Jan 08 11:56:28 aholler_: with networkmanager, that's not so basic Jan 08 11:56:42 aholler_: actually, with networkmanager it becomes rocket science Jan 08 11:56:43 KotH: I *think* back when we had to do this a lot it was 9.xish timeframe and our lab machines just disabled netmanager..so that sounds about right..in that timeframe networkmanager could do much less than the little it can do now Jan 08 11:57:18 Have anyone tried to connect an IP (Ethernet) cable between a PC and BeagleBone directely? Jan 08 11:57:33 KotH: I do remember thinking that they designed the network scripts and such for the 99% use case rather than somebody hosting a usbnet connection to a target ;) Jan 08 11:58:04 KotH: but we had to document it for customers...reason we at least tried to use Ubuntu Jan 08 11:59:28 for usbnet the pc has to play server, and most people wouldn't start networkmanager on a server. but the only problem is, tutorials for configuring networkmanager seems to be rare Jan 08 12:00:09 hrm, I wonder if anybody would care about a J6-based Beagle*. Jan 08 12:00:17 but it has a config as everything and this config isn't that complicated Jan 08 12:00:24 J6? Jan 08 12:00:34 panto, a g+ reference ;) Jan 08 12:00:54 https://plus.google.com/u/0/108244279740379322507/posts/WHUUoGPBtbL Jan 08 12:00:55 jacinto? Jan 08 12:01:15 TI sure has a love affair with vertical markets Jan 08 12:01:17 J6/OMAP Jan 08 12:01:30 it's love in an elevator Jan 08 12:01:56 phones burned, now attack the cars ;) Jan 08 12:02:03 the new warewolf6 omap processor for the women's changing rooms pervert market! Jan 08 12:02:28 better feature recognition, less chance of capture! Jan 08 12:02:33 panto, when you read Brad's post, you can see the excitement just like we sorta had before the reality of that automotive market sets in. Jan 08 12:02:50 vertical markets suck IMO Jan 08 12:02:55 mdp: 99% use case? have fixed ips become so out of fashion? Jan 08 12:03:02 that particular one real sucks Jan 08 12:03:03 but what do I know? I'm a stupid engineer Jan 08 12:03:10 KotH: AFAICT, yes ;) Jan 08 12:03:18 * KotH is outfashioned then Jan 08 12:03:22 me too Jan 08 12:03:26 (with a slight automotive industry burn) Jan 08 12:03:28 mdp: all my machines at home have fix ips Jan 08 12:03:35 mine too Jan 08 12:03:36 mdp: and public at that too.. including the printer :) Jan 08 12:03:43 well, it works fixed for an ethernet device Jan 08 12:03:49 what's so hard with dhcp? Jan 08 12:03:59 I recall that networkmangler just had it's hate of usbN hardcoded Jan 08 12:04:01 * panto admits settings up dnsmasq and doing it assignments of the home network there Jan 08 12:04:43 I have stuff like network printers and infrastructure doing dhcp with a fixed IP lease via MAC..I find that more convenient for those Jan 08 12:04:48 panto, +1 Jan 08 12:04:51 it's an admission of the fact that everything is consumer oriented nowadays, where everything is dhcp based Jan 08 12:05:25 until v6 arrives Jan 08 12:05:30 the fact that dnsmasq has a fully rocking tftp server is even better Jan 08 12:05:40 aholler_: with the year of the linux desktop? Jan 08 12:05:45 aholler_: it's yet another system that might fail Jan 08 12:05:54 aholler_, even if ipv6 arrives most people are too stupid to be directly connected to the internet Jan 08 12:06:06 aholler_: my network at home is designed in a way that each and every machine can fail w/o much impact on what i can do Jan 08 12:06:08 panto: that never will change Jan 08 12:06:15 aholler_: a dhcp server would be a spf Jan 08 12:06:21 hence nat will live on Jan 08 12:06:39 KotH: use two of them Jan 08 12:07:02 aholler_: two of them to have kept in sync Jan 08 12:07:19 impossible to manage Jan 08 12:07:25 juup Jan 08 12:07:31 it's just a matter of complexity Jan 08 12:07:38 i can do everything of that Jan 08 12:07:40 no problem Jan 08 12:07:43 panto, I find myself looking at the latest state-of-the-art in pci bus analyzers...it's been so long :) Jan 08 12:07:44 but it takes time Jan 08 12:07:54 mdp, hehe Jan 08 12:07:56 fix ips are easy to do, easy to manage Jan 08 12:08:21 aholler_: and as long as it just works for me... Jan 08 12:08:30 aholler_: on wireless otoh, i use a dhcp server Jan 08 12:09:33 KotH, wait until you have to tell your wife/gf how to setup fixed ips to use her laptop in your house :) Jan 08 12:10:11 panto: windows: no problem (at least xp, havent tried win7), macos: no problem, ubunto: no way in hell will that enter my home! Jan 08 12:10:17 ;) Jan 08 12:10:34 omg Jan 08 12:10:42 will you allow Linux? Jan 08 12:11:03 only GNU/Linux Jan 08 12:11:25 <_av500_> BSD/Linux Jan 08 12:11:27 with extra RMS compliance Jan 08 12:11:35 * panto wonders what password rms uses in his wifi AP Jan 08 12:12:01 panto: someone who browses the web using email does not have wifi Jan 08 12:12:25 gee, forgot about that one Jan 08 12:12:27 <_av500_> KotH: of course not, there is no "free" wifi driver Jan 08 12:12:38 <_av500_> i guess he is bitbanging ethernet Jan 08 12:12:45 <_av500_> or maybe uucp Jan 08 12:12:48 <_av500_> over serial Jan 08 12:12:58 * panto wonders if it's possible to bitbang 10M ethernet on the PRU Jan 08 12:13:09 without rms we all would have to use win. Jan 08 12:13:13 panto: probably Jan 08 12:13:36 panto: i'd even say that a 100mbit should be possible Jan 08 12:13:46 panto: you only have to get 4bit@25MHz out Jan 08 12:13:50 that should be possible Jan 08 12:13:55 with PRU, all things are possible Jan 08 12:13:56 hmm, yeah Jan 08 12:14:02 not bad, not bad at all Jan 08 12:14:16 mdp: 32bit DAC? Jan 08 12:14:25 just use ethercat and forget ip networking ;) Jan 08 12:14:33 KotH: "fix it in software!" Jan 08 12:14:37 lol Jan 08 12:15:09 there is actually something i want to do, that would require a DAC that acheives 32bit resolution Jan 08 12:15:39 KotH, err, actual 32bit resolution? Jan 08 12:15:47 yes Jan 08 12:15:55 <_av500_> koCALIBATE YOUR GOLDEN EARS? Jan 08 12:15:57 <_av500_> OOPS :) Jan 08 12:16:00 <_av500_> oosp Jan 08 12:16:06 <_av500_> rgh Jan 08 12:16:06 mdp: the demise had touched you hard ;) Jan 08 12:16:13 1bit delta sigma maybe? Jan 08 12:16:36 aholler_: "I'm not dead yet!" Jan 08 12:16:39 panto: getting from there to 32bit w/o being burried in noise is damn difficult Jan 08 12:16:49 dunno, making a 32bit dac directly is pretty hard Jan 08 12:17:00 panto: on the other hand... getting 32bit w/o being burried in noise is damn difficult no matter what ^^' Jan 08 12:17:00 you're fighting with noise Jan 08 12:17:28 in other words you might have a 32bit adc but it's only worth for 24bits or something at best Jan 08 12:17:47 >24bit is doable Jan 08 12:18:01 and has been demonstrated doing PWM based DACs Jan 08 12:18:06 <_av500_> KotH: make a resistor ladder DAC :) Jan 08 12:18:15 there's always the physical world you connect to Jan 08 12:18:30 what kind of physical properties require 32bits of precision? Jan 08 12:18:38 something very expensive/and or scientific Jan 08 12:18:45 anyway, I have to eat Jan 08 12:18:46 later :) Jan 08 12:18:48 <_av500_> panto: female color vision Jan 08 12:18:55 lol Jan 08 12:18:55 omg Jan 08 12:18:59 never though about that Jan 08 12:18:59 *g* Jan 08 12:19:03 64bit color! Jan 08 12:19:13 <_av500_> deep color Jan 08 12:19:19 panto, _av500_ is *wise* Jan 08 12:19:19 it's fuschia you dolt? can't you tell the color? Jan 08 12:19:36 "teal! teal is the color of the dresses!" Jan 08 12:19:38 men have at best 16color palette Jan 08 12:19:41 "Huh?" Jan 08 12:19:43 hehe, l8r Jan 08 12:21:50 _av500_: actually, AD makes a ADC with 31bit resolution (iirc 28bit real) Jan 08 12:22:57 * KotH wonders whether colourblindnes is a predominantly male feat Jan 08 12:22:58 panto: thanks for confirming that noone can spell fuchsia correctly: http://blog.xkcd.com/2010/05/03/color-survey-results/ Jan 08 12:24:20 koen, I spell it as "reddish-purple" thank you. Jan 08 12:24:48 I will not be trained Jan 08 12:25:09 koen: beige is also a nice name that isnt possibly spelled correctly Jan 08 12:26:42 though, interstingly, i hardly know any non-english natives who have problems with either spelling fuchsia or beige Jan 08 12:27:20 "tan" Jan 08 12:27:31 non-english doesn't exist for native english people Jan 08 12:27:51 aholler_: it's a simplified state of affairs ;) Jan 08 12:28:59 * KotH wonders how long it will take until the english speakers will fix up their spelling Jan 08 12:30:09 like the germans did... eg "portemonaie" became "portmonee" Jan 08 12:30:15 KotH: I'm hoping we can get the UK to drop their antiquated spellings and use our improved versions. Jan 08 12:30:33 color colour? Jan 08 12:30:38 KotH: thats just wrong Jan 08 12:30:42 dough -> doh ? :) Jan 08 12:30:57 aholler_: hehe Jan 08 12:30:58 bradfa, yes, we have the correct spelling in the *nix tradition ;) saving bandwidth for the world! Jan 08 12:31:10 C Jan 08 12:31:17 mdp, while we're at it, can we make them pronounce things correctly? Jan 08 12:31:18 aholler_: most people who've learned the french spelling still use it, but the new spelling is taught at school Jan 08 12:31:21 pavement and sidewalk are both 8 chars Jan 08 12:31:26 bradfa, in time, in time! Jan 08 12:31:29 aluminum anyone? Jan 08 12:32:05 mdp, the Canadians too Jan 08 12:32:10 <_av500_> bradfa: yes, I have a nice Louisville Slugger :) Jan 08 12:32:10 bradfa, I suspect there's a movement on to get the rest of world of that weird scientificy metric system. Jan 08 12:32:12 we have a bunch of those around here Jan 08 12:32:20 s/of the/off the/ Jan 08 12:32:23 mdp: can you in turn adapt the worlds numeral system: ie a billion is 10^12 not 10^9 Jan 08 12:32:31 <_av500_> mdp: mention metric only when ds2 is asleep Jan 08 12:32:46 mdp, I'm OK with metric, so long as I can keep my distance per unit volume for calculating car fuel economy Jan 08 12:32:50 _av500_, a trigger? Jan 08 12:32:54 none of this volume per unit distance junk Jan 08 12:32:54 <_av500_> yes Jan 08 12:33:00 at least we accept that people have different feet Jan 08 12:33:14 <_av500_> happy feet Jan 08 12:33:20 very happy Jan 08 12:33:27 <_av500_> very feet Jan 08 12:33:27 aholler_: we are conformists Jan 08 12:33:45 <_av500_> not confederates? Jan 08 12:35:28 _av500_: that ship has sailed Jan 08 12:35:34 _av500_, confederates aren't really that popular up north Jan 08 12:35:44 _av500_, maybe down in Texas? Jan 08 12:36:11 bradfa, go East ;) Jan 08 12:37:08 mdp, confederates are more popular if I go east? To where? Syracuse? :) Jan 08 12:37:29 you stated a starting point of Texas...at least implicitly Jan 08 12:37:48 taht would be spain then :) Jan 08 12:37:54 mdp, sorry, coffee has been put in mug but not yet put into head Jan 08 12:37:59 * bradfa puts coffee into head Jan 08 12:38:15 bradfa, in any case, confederates are popular in pockets here..especially in the rural areas. Jan 08 12:38:28 "popular" Jan 08 12:38:34 mdp, I can see that in ohio Jan 08 12:38:45 probably some rural areas around here, too Jan 08 12:38:49 yes Jan 08 12:39:09 there's a reason it's a swing state Jan 08 12:39:22 many reasons Jan 08 12:39:26 I saw a confederate flag on the back of a car at the supermarket this weekend, it had flat tires. correlation or causation? Jan 08 12:39:40 correlation Jan 08 12:41:06 I had a brake light out and and NRA sticker on my vehicle...that's probably correlation too. :) Jan 08 12:41:28 mdp, No Reasonable Assumptions? Jan 08 12:41:47 no reasonable arguments Jan 08 12:41:53 prejudice does flow in all directions...that's a given. :) Jan 08 12:42:19 bradfa, you having a "heat wave" up your direction too? Jan 08 12:42:28 mdp: i was surprised when i learned that a friend of mine, who has been working in SF for a couple of years, joined the NRA :) Jan 08 12:43:08 mdp, yes, it's nice out this morning, supposed to hit 40 this weekend Jan 08 12:43:25 calm before the rest of winter... I presume Jan 08 12:43:32 KotH: most people don't understand the difference between NRA, the educational org and owners club..and the NRA-ILA, the separate entity that's the lobbying org...that helps to better understand things Jan 08 12:43:46 meh.. oo programming.. as if procedural isnt already hard enough for most people!

Jan 08 12:48:27 mdp: it's not only about entitlements Jan 08 12:48:42 mdp: part of it is also that if all that shit fails, people will be starving Jan 08 12:48:57 and that w/o any natural catastrophe or war Jan 08 12:48:57 <_av500_> mdp: somebody comes to take away your heated driveway, people rebel!

Jan 08 12:50:48 mdp: not being taken care of? Jan 08 12:51:13 mdp: uhm.. i dont know whether it's true, but we heard stories about people getting up to 18 months of salary per year in .gr Jan 08 12:51:38 mdp: if they have been working for the government that is Jan 08 12:51:50 KotH: we have that type of thing here too Jan 08 12:51:53 bbl Jan 08 12:52:14 mdp: oh.. so you will be out on the streets as well, in the near future? :) Jan 08 12:55:58 KotH, the .gr story is pretty simple; there are the chosen ones (working in the .gov sector) and the slaves that have to feed them (the private sector) Jan 08 12:56:38 panto: sounds like in any "democracy" Jan 08 12:56:52 KotH, well, the money has run out Jan 08 12:57:04 and the increased taxes are just delusional Jan 08 12:57:15 if people pay them Jan 08 12:57:27 they have tried anything besides reducing what's causing it; the size of the government Jan 08 12:57:34 aholler_, they won't Jan 08 12:57:51 panto: and many didn't Jan 08 12:58:27 aholler_, the only way to survive is not paying taxes that aren't doing anything good to _you_ Jan 08 12:58:39 but they do pay the pensions of people you know at the ripe age of 50 Jan 08 12:58:42 * KotH ponders forbidding anyone w/o proper training in software architecture to write oo code in his company Jan 08 12:59:04 KotH: you want to leave? ;) Jan 08 12:59:17 so paying taxes in .de (no problem - you get something in return) Jan 08 12:59:20 aholler_: no i want to beat a few people with a lart Jan 08 12:59:32 paying taxes in .gr (no benefit to you personally) Jan 08 12:59:37 panto: that isn't true, it's annoying here too Jan 08 12:59:50 panto: actually, ze germans come to .ch because they pay less taxes here Jan 08 12:59:59 panto: beside earning more money in general Jan 08 13:00:33 I think Thatcher said it best, the socialist will eventually run out of other people's money Jan 08 13:00:46 * panto <- points to his home country Jan 08 13:03:00 well.. do you think such arguments will convince anyone?

Jan 08 16:02:15 v4 is imminent..and will remove the RFC label..looking to hit the next window Jan 08 16:02:24 * mranostay hands that off to panto Jan 08 16:02:25 mdp: ok, nice Jan 08 16:02:40 mdp: seems am335x is broken in mainline atm though Jan 08 16:02:45 first version that addresses all known issues Jan 08 16:02:58 jacmet, how? I'm running on -rc2 Jan 08 16:03:02 ish Jan 08 16:03:20 mdp: ahh, with an appended dtb? Jan 08 16:03:35 mdp: I'm seeing the same hang as Paul: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg82297.html Jan 08 16:03:36 no, mainline u-boot and dtb passed in properly Jan 08 16:03:49 mdp: ok, will give that a try Jan 08 16:04:15 mdp: appended dtb is just easier to manage Jan 08 16:04:30 IMHO, if the whole point of DT is kernel independence, appended dtb is silly Jan 08 16:04:50 mdp: don't get me started on the pro/cons of DT ;) Jan 08 16:04:58 would DT help with that? Jan 08 16:05:17 mdp: actually it is not Jan 08 16:05:17 mdp: for most embedded designs people don't really care about board independence Jan 08 16:05:22 Jacmet, what's the problem? Jan 08 16:05:24 I build one .config + 3 dtbs for the 3 am33x boards I test..then load each from Jan 08 16:05:36 mdp: if you have silly bootloaders who dont know how to handle dtbs then it's cool to append them Jan 08 16:05:45 Jacmet: you're preaching to the choir..I've been down this path long before ARM decided to do DT ;) Jan 08 16:05:48 mdp: eg the i.mx bootloader is one of those cases Jan 08 16:05:55 panto: problem about dt in general or seperate dt? Jan 08 16:05:56 mdp: cant even properly pass kernel parameters Jan 08 16:06:04 mdp: I know, I also used to do ppc Jan 08 16:06:06 Jacmet, I have it fixed in my kernel Jan 08 16:06:35 the issue is that the dtb's are now generated in the boot/dts/ directory, instead of boot/ Jan 08 16:06:41 hang on Jan 08 16:06:43 KotH: or if you just got your fingers burned in the past with version dependencies between dtbs and kernels, so you now want them together Jan 08 16:06:58 panto, yeah, I had to update my build/deploy script for the constant churn :-/ Jan 08 16:07:03 churn churn churn Jan 08 16:07:05 panto: what does that have to do with the early boot hang? Jan 08 16:07:36 oh.. and i like dt! for a dumbfuck like me dt is much easier to handle than boardconfigs Jan 08 16:07:37 are you sure that the concatenated image contains a dtb? Jan 08 16:07:40 * Jacmet updated buildroot to handle the new location around xmas Jan 08 16:07:57 Jacmet: at least this shows how many corner cases there are for "works" and "doesn't work" Jan 08 16:08:23 and what is your config? Jan 08 16:08:38 if you enable early printk for example you will hang Jan 08 16:08:39 panto: yes: make ARCH=arm CROSS_COMPILE=arm-linux- && cat arch/arm/boot/dts/am335x-bone.dtb >> arch/arm/boot/zImage&& make ARCH=arm CROSS_COMPILE=arm-linux- uImage Jan 08 16:08:56 panto: this is with bog standard omap2plus_defconfig Jan 08 16:09:00 KotH: when done correctly it becomes data stored in a .c file version data stored in a .dts file. same crap, different format Jan 08 16:09:12 the latter allows some different use cases is all Jan 08 16:09:22 there's no such thing as bog standard I'm afraid Jan 08 16:09:31 omap2plus_defconfig breaks more often than not for me Jan 08 16:09:39 mdp: ack Jan 08 16:09:45 KotH: there is zero change to the requirement to have knowledge of what data to put in those files though Jan 08 16:09:51 mdp: but for me dt was easier to grasp and modify Jan 08 16:10:02 mdp: yes, call me dumb :) Jan 08 16:10:11 anyway, I'll build a new u-boot and try with a seperate dtb Jan 08 16:10:14 thanks Jan 08 16:10:20 KotH: nope, not dumb..it's standardized acorss all platforms and that has value Jan 08 16:10:40 versus each arch/subarch having a different abstraction and data structure format for handling board file level data Jan 08 16:11:10 KotH: so it makes sense that it's easier to understand Jan 08 16:11:40 but that only extends as far as the device specific bindings ;) Jan 08 16:12:09 mdp: even the rest Jan 08 16:12:14 cpsw looks vastly different than a gianfar h/w description...but both are gige. Jan 08 16:13:14 mdp: i worked with a soc that was barely supported in linux at that time. doing modifications using the dt system (not just the dt file, but c code related to dt as well) was easier for me, then the arm board structs Jan 08 16:13:19 KotH: I suspect once *everything* has bindings, people will find the .dts* to be nearly incomprehensible. Jan 08 16:13:40 mdp: tried the later first, failed. i was quite glad dt support was introduced just a week or two prior to that Jan 08 16:13:48 heh, cool Jan 08 16:14:29 with dt it was litterly just a day of reading docu, another day of trying the settings and it magically worked Jan 08 16:14:34 litteraly* Jan 08 16:14:57 mdp, not everyone has spend ages hacking a board files like us Jan 08 16:15:24 but that's probably because i have had hardly any exposure to embedded linux prior to that task, so i never learned the board config stuff at all Jan 08 16:15:24 we know our way around it now, but for a fresh guy, the dt is more easily understood Jan 08 16:15:40 exactly Jan 08 16:15:54 panto, you can't compare a typical shitty ARM subarch level of board file abstraction with one that has proper DT support...it's an unfair comparison Jan 08 16:16:17 mdp: all SoC manufacturer supplied code is shit Jan 08 16:16:20 well, let's talk specifics Jan 08 16:16:28 mdp: so it's not unfair at all ;) Jan 08 16:16:28 take am33xx Jan 08 16:16:43 panto: the difference is that most people hacking on linux/embedded stuff knows C, but not everyone knows DT Jan 08 16:16:50 panto, as you know, it can be done just as nicely in C, but you give up some of the features of the independent data format approach of DT is all Jan 08 16:16:50 which do you think is easier to modify? the am335xevm board file or the dt? Jan 08 16:17:02 I disagree there Jan 08 16:17:15 panto, you can't use am33xx...it's been an example of a shitty vendor tree board file "abstraction" Jan 08 16:17:19 as is omap in general Jan 08 16:17:33 mdp, that's a completely fair use :) Jan 08 16:17:41 all the SoC manuf. board code is like that Jan 08 16:17:51 I think you need to travel away from ARM to find good examples Jan 08 16:17:54 mdp: are you telling us, that there are no nice board files in the arm subtree? ;) Jan 08 16:17:55 and on top of that, each one is different, and has different conventions Jan 08 16:18:14 KotH: I've never seen one, but haven't work on all arches Jan 08 16:18:19 dt might have issues, but they are common issues for all Jan 08 16:18:33 just samsungs, fsl, and ti Jan 08 16:18:42 and ones that aren't upstream ;) Jan 08 16:18:48 and unfortunately ppc is not all that used for most people Jan 08 16:18:58 panto, that's why it's better Jan 08 16:19:26 it's simpler because it deals with a simpler problem space Jan 08 16:19:29 panto, it was..and it was an example of how things were properly abstracted and easy to port with a .c/.h abstraction Jan 08 16:19:44 DT provided features other than "readability" there ;) Jan 08 16:19:44 apropos fsl... has anyone here tried the olinuxino boards from olimex? Jan 08 16:19:59 they are as cheap as the rpi, but w/o all that bitbang shit Jan 08 16:20:12 unfortunately as you know, we can't fix the way the ARM move to DT has been done Jan 08 16:20:23 panto, and do note, that ARM is barely even started with implementing all the bindings needed to cover the complete problem space that implemented in just _existing silicon_ Jan 08 16:20:31 agreed Jan 08 16:20:34 panto, but we can bitch about it, yes? Jan 08 16:20:38 you don't have to tell me about it :) Jan 08 16:20:41 * panto stabs the world Jan 08 16:20:41 ;) Jan 08 16:20:52 that's what I was trying to get out of you Jan 08 16:21:06 I'm pissed off already messing with early printk Jan 08 16:22:07 add early console too ;) Jan 08 16:22:18 panto, did you see arnd's comments about ev3 on g+? Jan 08 16:22:32 he's downright giddy about getting upstream support for it..hehe Jan 08 16:22:40 1:) Jan 08 16:22:42 -1 Jan 08 16:22:43 hehe Jan 08 16:22:49 lol Jan 08 16:23:06 ev3 is a shiny thing like mobile phones Jan 08 16:23:16 ev3-with-one-motor.dts ev3-with-two-motors.dts ev3-with-motor-and-sensor.dts Jan 08 16:23:23 LOL Jan 08 16:23:31 #dtallthethings Jan 08 16:23:43 DT can help with that Jan 08 16:23:49 we'll need edma for ev3, no? Jan 08 16:23:59 panto: can it walk the dog? Jan 08 16:24:15 koen, a little foreshadowing...we need edma for _everything_ ... Jan 08 16:24:26 it's proliferating Jan 08 16:24:52 also in dra7xx Jan 08 16:25:47 though it may be mostly intended for the c6ks that are publicly mentioned as being in there Jan 08 16:25:59 Basic stuff here, I deleted uImage and replaced it with a new one and u-boot complains it cannot find /boot/uImage, any clue what I messed up? Jan 08 16:26:26 jsabeaudry: never delete just move :) Jan 08 16:26:33 dpaste.org Jan 08 16:28:07 Jacmet: btw, I was extremely pleased with how jonhunter's DMA OF helpers/bindings made defining/routing dma channels in .dts. so don't think I hate on DT :) Jan 08 16:29:11 mdp: ;) Jan 08 16:30:02 Jacmet: being able to just add a "dmas = <&edma 12>;" in one of my test driver DT nodes is quite sexy, IMHO. Jan 08 16:31:32 mranostay, so I have to format the partition and copy files in the right order? Jan 08 16:31:48 panto, btw, I think I'm going to submit the .dts pieces "correctly" the way we talked about Jan 08 16:31:56 * panto nods Jan 08 16:32:01 panto, where it can actually be used by the in-driver pinctrl support Jan 08 16:32:16 I can't stand all the dmesg noise Jan 08 16:32:25 oh god the early printk code is such a crufty relic Jan 08 16:32:28 I don't want to fight with the other people submitting stuff done incorrectly Jan 08 16:32:52 panto, are you going to add "early DT" support so we can have earlyprintk again? ;) Jan 08 16:33:39 I tried for a couple of hours, but it's more work than that Jan 08 16:33:49 there's nothing that disallows it Jan 08 16:34:05 it's just software, we can do anything ... with enough budget Jan 08 16:34:22 but you'd have to walk the flat tree in assembly to find the address of the uart registers ;) Jan 08 16:34:57 maybe you should do something more useful and go resolve the proper way to fix the debugss clock issue upstream? joel_ seems to have given up on that one Jan 08 16:35:12 so I said screw it, use the MACH_AM335XEVM defines for now Jan 08 16:35:13 :P Jan 08 16:35:38 panto, I went back to log_buf dumping myself Jan 08 16:35:40 seems like it's u-boot related Jan 08 16:35:44 mdp, don't Jan 08 16:35:46 but still needed the debugss clock hack Jan 08 16:36:11 use this: http://pastebin.com/unYz1urZ Jan 08 16:36:17 this works Jan 08 16:36:34 yeah, I was happy with my one line jtag fix Jan 08 16:36:44 mdp: openocd? Jan 08 16:36:56 yes, unmodified beaglebone Jan 08 16:36:57 did you see the hwmod crash protection fix I posted? Jan 08 16:37:04 yes, very nice Jan 08 16:37:22 it's one thing to fail, but crash like this... meh Jan 08 16:37:34 it's a feature Jan 08 16:37:54 RMK: "So much for DT sorting out world hunger Jan 08 16:37:55 and it never failing to solve any problem..." Jan 08 16:38:35 hehe Jan 08 16:38:42 I shouldn't start railing on RMK, but I just might Jan 08 16:39:54 panto: peace and love man Jan 08 16:40:11 this mach-id mess is all ARM specific crap Jan 08 16:40:30 I still don't get it even after all this years Jan 08 16:40:33 *these Jan 08 16:41:21 I btw find it odd how TI strips all mention of crypto support in the public TRM but then happily writes about it on the wiki Jan 08 16:41:29 err, mdp, how can I go about to fix the debugss clock thing? Jan 08 16:43:27 it's a semantics issue upstream...see this: http://comments.gmane.org/gmane.linux.ports.arm.omap/89575 Jan 08 16:43:52 and http://www.mail-archive.com/linux-omap@vger.kernel.org/msg81248.html Jan 08 16:45:36 so as you see, the technical issue is trivial...on current mainline I just use: https://gist.github.com/4485361 to do my work Jan 08 16:45:52 it just needs somebody to drive an acceptable patch that meets requirements Jan 08 16:46:05 Vaibhav seems to handle it, but what do you want? a kernel command line switch? or a dt one? Jan 08 16:47:58 panto, with u-boot's poor support for env load/save from mmc, I personally find it quicker in a devel env to just rebuild the dtb and reboot ;) Jan 08 16:48:13 in a perfect world I'd edit bootargs easily Jan 08 16:48:16 * panto whispers (me too) Jan 08 16:48:29 don't get me going about uEnv.txt Jan 08 16:48:41 say mdp, what's the deal with uEnv.txt? Jan 08 16:48:42 I would kill for a nand Jan 08 16:48:57 does anyone know if pandaboard can do dual output to HDMI and LVDS? Jan 08 16:48:57 the failure is not saving that crummy file Jan 08 16:49:11 AFAIK barebox actually does mmc-based env seamlessly (correctly) Jan 08 16:49:15 not cloning, but two framebuffers Jan 08 16:49:38 panto, makes me want to explore switching to barebox Jan 08 16:50:01 it will just be broken in a different way Jan 08 16:50:04 panto, uEnv.txt is a special case... Jan 08 16:50:08 panto, probably Jan 08 16:50:13 buZz: it will depend if the gen9 frankenkernel supports that ;) Jan 08 16:50:21 panto, need more trained bootloader writing monkeys Jan 08 16:50:52 dm8tbr: hehe well kernels are ment to be recompiled right ;) Jan 08 16:51:28 buZz: sure for infinite amounts of time Jan 08 16:51:44 there is a reason i just work 24 hours a week :P Jan 08 16:51:55 rub it in Jan 08 16:51:57 mdp, last message http://www.mail-archive.com/linux-omap@vger.kernel.org/msg81272.html seems to imply it is going to be handled Jan 08 16:52:24 the implication was a little weak to me Jan 08 16:52:29 but hopefully, yes Jan 08 16:52:49 I think I'll just go ahead and try to use robclark's drm driver Jan 08 16:53:54 I just decided to stop to see which tree solidifies best...too much churn. Jan 08 16:53:58 I'm back to driving tests Jan 08 16:55:08 mdp: whats so hard loading the dtb with u-boot? Jan 08 16:56:13 aholler_: nothing, that's what I do Jan 08 16:58:01 I do it just like with uEnv.txt and through uEnv.txt the filename for the dtb is variable Jan 08 17:00:34 panto, let me know if you see a patch submitted since the discussion ended 1.5 months ago..I might have missed it in my mbox Jan 08 17:00:42 and searches Jan 08 17:00:54 err, no I haven't seen it Jan 08 17:02:15 that was right before the great purge and slowdown though. Jan 08 17:14:11 mdp: even stalin would be impressed? :) Jan 08 17:16:26 :( Jan 08 17:19:17 just use an eeprom to provide the u-boot env Jan 08 17:19:28 if no flash is available Jan 08 17:19:53 arn't those already required for capes? Jan 08 17:20:27 u-boot-env-cape ;) Jan 08 17:21:23 aholler_, actually there is an eeprom on the baseboard Jan 08 17:21:34 which no-one uses Jan 08 17:21:40 yep Jan 08 17:21:55 actually, it's used for single u-boot image operation Jan 08 17:22:03 so it should be a thing of minutes to use that for the u-boot env Jan 08 17:22:16 aholler_: does it require development? Jan 08 17:22:29 I don't think so. Jan 08 17:22:45 Tartarus: ^^^ Jan 08 17:22:48 I assume u-boot can already read/write from eeprom Jan 08 17:23:04 it can...wondering why our people don't do this by default Jan 08 17:23:24 as the eeprom on the baseboard is required by all the ref boards in the am33x family Jan 08 17:23:47 so it's something like read_to_mem;env import Jan 08 17:24:10 or env export;write_from_mem Jan 08 17:24:59 I wonder how to monetize such ideas ;) Jan 08 17:25:24 av500 is all about monetization, check with him Jan 08 17:25:29 should make a patent :) Jan 08 17:25:43 unfortunately I don't live in the us Jan 08 17:25:48 some of us just do it for hack value ;) Jan 08 17:26:34 aholler_: I have an IP lawyer friend who will take care of the filing as long as you allow me to join in the patent disclosure Jan 08 17:27:25 disclosure of exact steps? Jan 08 17:27:36 aholler_: and clearly this is a great invention, congrats to us ;) Jan 08 17:28:07 I'm awaiting an ev30 sample ;) Jan 08 17:28:16 me too Jan 08 17:28:39 just send it to me ;) Jan 08 17:28:59 s/ev30/ev3/? Jan 08 17:30:19 ups, yes ;) Jan 08 17:30:30 mrs mdp asked me why we don't get a free sample of all the cool stuff that comes across my desk...I say, "life is cruel and unfair!" Jan 08 17:32:00 brick would be enough, I have enough of the required plastic around ;) Jan 08 17:33:09 +1 Jan 08 17:35:29 ugh, drive dying...hurray for raid Jan 08 17:40:05 panto, also still have the fortran numbered IPs upstream ;) Jan 08 17:40:16 yes Jan 08 17:40:49 every time I change something in my series I have to quadruple check my thinking there..good grief Jan 08 17:45:56 hmm, I should look around at lego, sometimes they have a dev program Jan 08 17:50:02 i'm back don't anyone panic Jan 08 17:59:10 we worry when we don't hear from you. Jan 08 18:00:32 mranostay, I almost alerted your local family members Jan 08 18:00:38 please be more careful Jan 08 18:08:57 hi pfefferz ! Jan 08 18:09:10 * mranostay flings some binary blobs at pfefferz Jan 08 18:09:15 hi mranostay Jan 08 18:09:21 splat Jan 08 18:11:56 heh Jan 08 18:20:33 * mranostay orders more geiger tubes Jan 08 18:21:12 i have a problem :) Jan 08 18:21:36 you are radiationd00d Jan 08 18:36:44 aholler_: bah, yes, u-boot can read/write the eeproms found on the bone, both the base one and any cape ones Jan 08 18:37:02 the 'eeprom' command even is enabled for a while now which does the batch write operation rather than individual i2c mw .... Jan 08 18:41:51 hey balister_ Jan 08 18:47:28 urg Jan 08 18:47:43 hi Crofton! Jan 08 18:47:57 better Jan 08 19:06:26 wmat: moose and quadcopters? :) Jan 08 19:06:43 absolutely! Jan 08 19:07:27 To bad it wasn't a bull moose though, as it would have charged Jan 08 19:07:45 don't pet the moose Jan 08 19:09:38 * wmat tries to keep BitBake/OE/Yocto separate :/ Jan 08 19:13:27 /Poky Jan 08 19:29:46 damn netmanager... making my hilight active Jan 08 19:30:07 mdp: type network manager next time Jan 08 19:30:26 everyone! switch to connman, quick! Jan 08 19:30:34 NetworkManager(tm) Jan 08 19:30:40 con man! Jan 08 19:36:36 Hi have a question: If I wanted to have a secure communication between the beaglebone, and a host through the network, what would be the best library to use? I have read into OpenSSL, would that work? Or is there something better out there? Jan 08 19:37:12 rot13 is all you need Jan 08 19:37:26 stunnel might be sufficient, depending on your needs Jan 08 19:37:30 ahmed_: and i think you mean a secure shell right? Jan 08 19:39:02 don't use a network if you need security Jan 08 19:39:33 irda? Jan 08 19:39:39 don't give physical access if you need security! Jan 08 19:39:42 don't snoop my photons! Jan 08 19:40:54 Lets say I have a server and client application running on host and pc respectively Jan 08 19:41:09 there will be a bunch of client Jan 08 19:41:33 they will take info from the environment and send it back to the server Jan 08 19:41:44 perhaps the host is not the correct term to use Jan 08 19:42:18 soso thats why was thinking to using openssl, which would something like stunnel work for server/client Jan 08 19:42:28 ?* Jan 08 19:44:08 sure, openssl or gnutls should do the trick Jan 08 19:46:36 * alan_o needs a nap Jan 08 19:46:51 or some caffeine..... Jan 08 19:47:13 alan_o: BEER! Jan 08 19:47:32 I think that's the opposite of what I'm looking for Jan 08 19:47:35 caffeinated beer? Jan 08 19:47:55 I think they've outlawed that here Jan 08 19:48:05 boooo! Jan 08 19:48:20 dump a 5 hour energy shot in a Sam Adams Jan 08 19:50:32 usually the ssl library is chosen due to licensing... Jan 08 19:51:12 if one doesn't need to exchang keys, just use any cipher, like aes Jan 08 19:52:08 aholler_: i read DES for a second... :) Jan 08 19:52:14 I am gonna have to look into this, but aren't we suppose to use certificates? Jan 08 19:52:33 we? Jan 08 19:52:49 if you look at the boost examples Jan 08 19:52:50 http://www.boost.org/doc/libs/1_52_0/doc/html/boost_asio/example/ssl/client.cpp Jan 08 19:53:33 who certificates your certicates? Jan 08 19:53:46 uups +f* Jan 08 19:53:58 who watches the watchmen? Jan 08 19:54:54 mranostay: green arrow Jan 08 19:55:33 mranostay: just bombed a phone interview, did good right up until they asked me to write a small drawing program :( Jan 08 19:55:37 I am not sure exactly, I will work without the CA set up, and just generate certificates Jan 08 19:56:00 or set up my own CA actually Jan 08 19:56:15 I am still looking into OpenSSL Jan 08 19:56:32 prpplague: i hate phone interviews Jan 08 19:56:38 agreed Jan 08 19:56:42 esp coding ones over the phone Jan 08 19:56:59 they are probably having a good laugh right about now, hehe Jan 08 19:57:34 prpplague: don't you fly today? Jan 08 19:57:49 mranostay: tomorrow morning Jan 08 20:05:36 prpplague: I bet you didn't bomb it Jan 08 20:06:57 i've learned usually the inverse of what i think actually happens :) Jan 08 20:07:08 unless i completely bomb it :) Jan 08 20:16:36 prpplague: what do they mean by drawing program? Jan 08 20:16:54 and how can you code that over the phone? Jan 08 20:17:07 * dm8tbr thinks of 'LOGO' Jan 08 20:17:10 mranostay, ✈ Jan 08 20:17:17 dm8tbr: woot, logo Jan 08 20:18:06 so is there a useful distro i can load on the FRI2? :) Jan 08 20:18:28 yocto^wangstrom Jan 08 20:18:35 mranostay: I use ubuntu on the desktop and it's great! Jan 08 20:18:45 mranostay: you should try it on your FRI2 Jan 08 20:18:53 * alan_o ducks Jan 08 20:23:33 dm8tbr: well correct if me i'm wrong but poky/yocto has no central package repo Jan 08 20:24:32 mranostay: as koen mentioned it takes zero time to build a repo yourself ;) Jan 08 20:25:26 ah that post Jan 08 20:25:32 alan_o: i think they were more interested in how i would organize the data structures Jan 08 20:26:01 alan_o: with generic shapes, i.e. circle, triangle, square, rectangle, parallelagram Jan 08 20:30:21 prpplague: so they were fishing for polymorphism? Jan 08 20:30:30 class Shape { } Jan 08 20:31:19 virtual void draw() = 0; Jan 08 20:31:47 * alan_o is begging for a stabbing from mranostay Jan 08 20:32:22 hehe Jan 08 20:32:37 prpplague, did you ask for requirements? Jan 08 20:33:43 Russ: i was about to ask for a SoW and, keeping with the training from TI, 6 check point meetings.... Jan 08 20:34:32 hehe Jan 08 20:34:36 exact steps? Jan 08 20:34:40 prpplague: I live in fear of those "coding interviews" ... I would fail miserably Jan 08 20:34:59 you probably did way better than you think Jan 08 20:36:30 mdp: hehe, well i didn't vomit on anything, so that is a plus Jan 08 20:36:49 good Jan 08 20:37:49 a friend shared me her google interview questions once...I was left thinking that I could never live through that shame ;) Jan 08 20:39:21 mdp: yeah, every time I see interview questions from somewhere big like that, I always wonder where they get people who can pass them. Jan 08 20:39:50 mdp: so I'm glad to see someone other than me say that :) Jan 08 20:40:06 one was relatively softball, explain processes and threads Jan 08 20:40:20 I bet a lot of people blow that one Jan 08 20:40:32 I have a friend who asks people to implement memcpy or memcmp Jan 08 20:40:35 and _most_ fail Jan 08 20:40:40 completely fail Jan 08 20:41:02 other was similar to prpplague's coding question..basically trying to see how you would approach breaking a problem into data sets Jan 08 20:41:21 yeah but doing it over the phone is a pain Jan 08 20:41:45 doing it f2f in an interview env period is a pain Jan 08 20:42:20 bed time Jan 08 20:42:47 cya tomorrow Jan 08 20:48:44 "tell me about your self" Jan 08 20:50:22 "I see you reporting to me in less than a year." Jan 08 20:50:29 try that one Jan 08 20:51:29 when i'm interviewing people Jan 08 20:51:43 i'm trying to figure out a few thign Jan 08 20:51:49 (a) what does this person know Jan 08 20:52:20 (b) what woudl i need to do to give them an environmetn where i'll get the best out of them, and they will want to stay and play Jan 08 20:52:29 …what will they do if I leave them in an office alone for 4 hours Jan 08 20:52:29 (c) what they want to do Jan 08 20:52:49 Russ, I don't want to know that. Jan 08 20:52:59 (d) how they will work with th rest of our team. Jan 08 20:53:41 (e) will they get blasted at linux conferences and end up in a fountain Jan 08 20:54:04 +1 I'm guessing? Jan 08 20:54:15 also, tell me more Jan 08 20:54:20 hehe Jan 08 20:54:52 Russ: wasn't that the 2002 OLS? Jan 08 20:55:17 I wasn't there Jan 08 20:55:54 Russ: hehe iirc it was 2002, they had like 10 people in the fountain out in front of the US embassy Jan 08 20:56:16 Trying to boot the kernel from angstrom/demo/beaglebone the kernel hangs at Waiting for root device /dev/mmcblk0p2, I tried fsck but it did not help, anyone else encountered the issue? Jan 08 20:57:05 I also formatted sd card, and started from scratch Jan 08 20:57:26 well u-boot can read it Jan 08 20:57:30 prpplague: yes, and it was repeated as an example of what not to do at the opening of each successive OLS ;) Jan 08 20:57:41 probably pastebin your boot log, maybe someone will take a look Jan 08 20:57:56 and elc has no such rule? Jan 08 20:58:40 there were no rules back then Jan 08 20:59:05 mdp: hehe Jan 08 20:59:38 prpplague: nice keeping up CA to US relations :) Jan 08 20:59:48 indeed Jan 08 20:59:53 prpplague: new death in paradise starting now on bbc1 Jan 08 21:00:05 koen: nice! no spoilers! Jan 08 21:00:08 koen: what is that? Jan 08 21:00:18 Russ, OLS is one of the confs cited by Val Aurora for "incidents"..that led to the LF anti-harassment policy Jan 08 21:00:20 true crime show? Jan 08 21:00:26 prpplague: I'm DVR'ing it, but signal quality is at 26%, so we'll see how it looks Jan 08 21:00:40 mranostay: a TV series modeled after prpplague's past Jan 08 21:00:57 http://en.wikipedia.org/wiki/Death_in_Paradise_(TV_series) Jan 08 21:01:06 the fountain incident in particular? Jan 08 21:01:45 mranostay: basically the first season is like my first year living in barbados, minus the murders Jan 08 21:01:53 Russ, the incidents were general comments and groping Jan 08 21:02:24 .oO(needs creeper cards...) Jan 08 21:03:20 dm8tbr: yea i've ordered some of those for ELC/ELCE, but in general i have not seen a need for it Jan 08 21:03:29 so have the policies weeded some of them out? Jan 08 21:03:33 dm8tbr: ELC seems to be a lot more professional Jan 08 21:03:46 prpplague: bummer Jan 08 21:03:57 we get plenty of professional at work :) Jan 08 21:04:02 hehe Jan 08 21:04:08 prpplague: you might want to read up on the 29C3 creeper-card fiasco though Jan 08 21:04:23 what happened? Jan 08 21:04:35 dm8tbr: hmm, i seem to recal reading that, but i don't recal the details Jan 08 21:05:51 they were handed out without any explanation. The event never really had a harrassment problem before. As it was a hacker conference, people got 'creative' with them. Jan 08 21:06:00 that's the very very fast forward version Jan 08 21:06:29 dm8tbr: oh right Jan 08 21:06:42 dm8tbr: seems like the creeps were keeping track of how many they got Jan 08 21:06:49 can we do the fountain thing at ELC, but without creeps? Jan 08 21:07:12 well there weren't creeps really, people made fun out of it and tried to obtain cards Jan 08 21:07:20 Russ: only if we can get mans to wear one of those borat swimsuits Jan 08 21:08:11 but there are much better accounts than what I can provide Jan 08 21:08:27 yes Jan 08 21:08:28 blog.fefe.de has some. use google translate Jan 08 21:08:32 * prpplague will go back an re-read Jan 08 21:09:20 dm8tbr: Rachel Blum on G+ keeps on a lot of these types of issues - https://plus.google.com/u/0/107226275692313566931/posts Jan 08 21:10:18 by no means I'm belittling the subject. Just the specific event was not done well in this context Jan 08 21:10:31 dm8tbr: understood Jan 08 21:10:42 I know you did, but there might be others Jan 08 21:11:07 dm8tbr: one of my goals for 2012 is to work on getting more women embedded developers active with ELC/ELCE for 2014 Jan 08 21:12:40 the elc deadline was extended to the 10th, right? Jan 08 21:12:47 yea Jan 08 21:12:55 as well as the android builder summit Jan 08 21:14:49 weeeee, my flight is ready for online checkin... Jan 08 21:16:47 does any know how how much the beagles clocks can drift over time? Jan 08 21:17:46 prpplague: I'm still thinking if I can come up with a topic that wouldn't sound like completely out of the wazoo... Jan 08 21:18:00 dm8tbr: hehe Jan 08 21:20:08 prpplague: you were kind of encouraging meta topics, weren't you? like not strictly 'this is how I fought embedded device XYZ into submission' Jan 08 21:20:49 but more like 'where is this embedded thing going?' 'why's this so blurry and overlapping' etc Jan 08 21:20:50 dm8tbr: correct Jan 08 21:21:06 prpplague: how many joke submissions do you typically get? Jan 08 21:21:16 "trolling the IRC for fun and profit" Jan 08 21:21:18 stuff like that Jan 08 21:21:33 alan_o: surprising we haven't had any Jan 08 21:21:47 alan_o: that could actually be a valuable submission. it would take place on the exact steps to the venue, right? Jan 08 21:22:21 dm8tbr: yeah, now you're getting somewhere.... Jan 08 21:22:48 prpplague: I'll think about it if I am confident to come up with a coherent enough story to fill a time slot etc Jan 08 21:22:50 "oh no, you don't understand; I don't _need_ presentation room" Jan 08 21:22:58 * prpplague heads of to prepare for tomorrow Jan 08 21:23:03 dm8tbr: dandy! Jan 08 21:23:06 s/need/want/ Jan 08 21:23:07 FTFY! Jan 08 21:24:40 alan_o, they're in dire need of a submission that violates "The Policy" Jan 08 21:24:48 that'll be a good start Jan 08 21:25:13 Thinking of making an account named Dave Anders and submitting some..... Jan 08 21:42:30 aholler_: looks like you also hit the lockdep splats Jan 08 22:17:31 welcome davest Jan 08 22:21:16 has anyone had any expereince with the LCD3 cape? Jan 08 22:24:03 mdp: with udlfb? yes Jan 08 22:24:31 I hit it on a similar driver...st7735fb that also uses defio Jan 08 22:24:40 that patch fixed it for me as well Jan 08 22:24:48 I may add my reply in to the ever growing thread Jan 08 22:28:30 morning mranostay Jan 08 23:08:03 mdp: but I'm not sure about what you are talking, I've just assumed it's udlfb, because that was the last patch I've posted ;) Jan 08 23:10:26 alan's original patch: https://patchwork.kernel.org/patch/1757061/ Jan 08 23:11:02 ah, that one. hmm, i didn't need it. Jan 08 23:11:36 at least I think so. but i use it anyway, so I can't really say ;) Jan 08 23:13:26 just write a "I am crap" helper ;) Jan 08 23:20:52 jkridner1: so how goes the judging? :) Jan 08 23:22:21 is the 'stache twitter active? Jan 08 23:22:45 stache twitter?

Jan 08 23:29:37 *is Jan 08 23:30:10 yes, also, sexual harassment is ok, so long as it occurs within an HR training video Jan 08 23:31:04 heh Jan 08 23:31:26 never had to take one of those.. yet... Jan 08 23:32:00 the TI one takes the above rule to new levels Jan 08 23:32:52 Russ: what is the training video an episode of Mad Men Jan 08 23:34:21 no, but I think the punishment for violating HR policies may be to appear in a future HR video Jan 08 23:35:10 hehe Jan 08 23:35:21 it is all TI employees in it? Jan 08 23:37:39 does it display creeper-cards when one touches it? Jan 08 23:38:08 mranostay, I can see Mad Men episodes be used in the HR training videos... "I'll not be talked to that way by a woman!!!" Jan 08 23:38:34 hmm..who was it that posted a link to those old videos on employing women? Jan 08 23:38:53 the good old days? :) Jan 08 23:39:05 i'm kidding of course Jan 08 23:39:12 mranostay, "What's wrong with this scenario?

Is there a tool for reading/writing registers on omap3? Jan 09 00:03:06 I would use omapconf, but README.md says OMAP3 is not supported. Jan 09 00:05:15 gabrbedd: hehe - over dependence on TI tools Jan 09 00:05:39 gabrbedd: devmem2 can be easily used to read/write physical registers on any linux based system Jan 09 00:07:42 prpplague: Thanks! I'll check it out. :-) Jan 09 00:08:19 gabrbedd: http://elinux.org/Board_Bringup_Utilities Jan 09 00:09:28 prpplague: so, just statically compile it and go? Jan 09 00:09:56 gabrbedd: yea if you don't have the same libs for your cross-compile environment Jan 09 00:10:12 gabrbedd: its has very few dependencies Jan 09 00:12:08 yo prpplague Jan 09 00:12:13 XorA: hey bud Jan 09 00:13:37 prpplague: whats going down?

Jan 09 00:28:36 best just to be logged in as root and be careful huh.. its like wiring the mains live Jan 09 00:28:47 if you know it dangerous you're always careful Jan 09 00:29:04 if you rely on the safeguards to keep yourself safe, you'll kill yoruself one day Jan 09 00:29:09 mmmm, AC juice Jan 09 00:29:11 when they fail.

Jan 09 02:54:21 mranostay, about 0.01 baud Jan 09 02:56:39 you can also multiplex Jan 09 02:56:39 and its probably handy to use pre-emphasis **** ENDING LOGGING AT Wed Jan 09 02:59:59 2013
