**** BEGIN LOGGING AT Fri Dec 27 02:59:58 2013 Dec 27 03:02:35 sheldonw: just pointing out when you use unsupported distro, you do have to understand the difference and why it is unsupported Dec 27 03:03:18 like I said, your real arrogant fuck, eh? Dec 27 03:04:03 sheldonw: most code that looks at the cape manager use 'bone_capemgr.*' when opening. The number is not a guarantee its the order it is loaded by the kernel. Dec 27 03:06:31 so, I want to enable a PWM on the P8 header, what is recommended to do this? Pins 45/46 specifically. Sorry for asking newbie questions, thought that's what an open chat system is for. Dec 27 03:07:07 a cape mgr file exists for that. I dont recall the name Dec 27 03:07:29 oh god do we have to have the Linux pissing contest again folks? Dec 27 03:07:38 there are number of pwm dtb entries with examples for PWM Dec 27 03:07:55 you can look at the bacon and bacone cape configurations as examples Dec 27 03:08:52 N2TOH: no pissing contest going on, exactly why none of the folks with experience help here any more... Dec 27 03:09:07 ^^^ words of an arrogant fuck Dec 27 03:09:45 oh darn Dec 27 03:09:55 ban me, boot me Dec 27 03:10:01 heh Dec 27 03:10:16 sheldonw: don't flatter yourself, i have other business to tend to Dec 27 03:10:18 I do have hopes that ubuntu will be more stable but last try a month or 2 ago it was a mess. Dec 27 03:10:33 then let other's answer and quit power trippin. Dec 27 03:10:41 sheldonw: I recommend learning how to conduct yourself properly on an "open chat" Dec 27 03:10:48 you are failing quite badly Dec 27 03:10:53 oh darn Dec 27 03:11:25 be courteous and show that you have done your own research, do not come in here with the attitude that you are entitled to any help Dec 27 03:11:28 * N2TOH conductive or amusing chat folks... Dec 27 03:11:50 oh this is quite funny actually. Dec 27 03:11:51 heh Dec 27 03:12:00 calling people "arrogant fucks" for telling you that what you are trying to do is not officially supported is... idiotic Dec 27 03:12:27 if you know better, then why are you here? Dec 27 03:12:32 didn't know this was the offically only support channel. been asking ubuntu related q's for months with legit answers bro. Dec 27 03:12:47 I'm not your bro Dec 27 03:13:06 ah hah. Dec 27 03:13:32 an epic hack is showing us we are all lazy, buy compiling a tut for porting your app over to a currently unsupported distro Dec 27 03:14:01 end transmission Dec 27 03:17:18 N2TOH: thanks for the link looks like a nice display will see how it does. Was surprised on its power usage though. Dec 27 03:17:25 honestly: hehe Dec 27 03:17:33 honestly: nice conclusion Dec 27 03:17:41 sad sad community going on here... Dec 27 03:18:10 and there was much rejoicing Dec 27 03:19:02 I do horrendously unsupported things on my beagleboards all day long Dec 27 03:19:25 I just don't expect anyone to want to help me until I've thoroughly done my homework Dec 27 03:19:26 Dr{Who} np your welcome as all of you are, you might want to set a reminder for the sample end date. as they seem to offer stuff on a regular basis Dec 27 03:19:28 honestly: hay now what you do with your bbb is between you and it :) Dec 27 03:19:31 *shrug* Dec 27 03:20:07 N2TOH: ya I bookmarked it thanks. Dec 27 03:20:28 don't forget to set a calandar reminder! Dec 27 03:20:33 not a bbb, bbxM Dec 27 03:20:37 10 of them Dec 27 03:20:50 bb4 and bb5 are dead and I haven't gone in to check... Dec 27 03:21:04 honestly, what about us poor ignorant BBB owners? Dec 27 03:22:03 I did something bad to a new bbb today but it didnt bite me. I reversed the polarity on the power supply I salvaged :) must be a diode built in lucky for me. Dec 27 03:22:13 yup Dec 27 03:22:25 * N2TOH bought a few RPi, and a single BBB in hopes of setting up an ultra low power draw cluster for the A/C cooling months Dec 27 03:22:28 bbxM survives wrong polarity too Dec 27 03:22:29 Dr{Wh0}: bbb is pretty robust with regards to damage Dec 27 03:23:00 funnily enough, it appears to draw pretty heavily since the power supply's status light becomes dimmer Dec 27 03:23:03 don't even want to know where it dumps that Dec 27 03:23:20 oh damn bb2 is also down Dec 27 03:23:22 heh. Dec 27 03:23:50 * N2TOH knows that the RPi will run from the stand by power from an common ATX PSU Dec 27 03:24:20 hopefully it will come back up in 2 hours if crond is still running and makes it reboot Dec 27 03:26:24 Nice idea N2TOH how many amps does that standby power support? I figured it was minimal but never checked any specs Dec 27 03:27:47 o.O Dec 27 03:28:14 sucking up to ops *does* work, I knew it! Dec 27 03:28:26 hehe Dec 27 03:30:25 Dr{Who} off the top of my head the spec says 2+ amps @ 5 volts Dec 27 03:31:05 keep in mind it's not the cleanest power, but it IS persistent Dec 27 03:36:14 N2TOH: C2 @10uf should handle any bounces. Dec 27 03:36:38 good to know Dec 27 03:37:31 other then my high AC line current, care to explain my higher then normal DC voltages from My classic Heathkit power supply? Dec 27 03:38:20 N2TOH: schematics plz Dec 27 03:38:32 hang on Dec 27 03:40:04 https://archive.org/details/HeathkitHp-23aPowerSupplyAssemblyManual Dec 27 03:40:17 I used the PDF link from that site Dec 27 03:40:17 N2TOH: by current I presume you ment voltage. Dec 27 03:40:32 yes Dec 27 03:41:11 the AC power at my OTH/10-20 is on the high side of the US spec Dec 27 03:41:22 typically around 125VAC Dec 27 03:42:05 so I have 125/250VAC rather then 120/240VAC Dec 27 03:42:22 not unusual. Dec 27 03:45:07 right right, well the power supply in question is circa late 60's Dec 27 03:47:14 I just resto-modded it with an update PCB board with modern parts, BUT this new board still has ZERO regulation. it's just a modern parts update of the original design. Dec 27 03:50:46 yep this is all analog and no regulation its all about that transformer and the voltage doublers. Dec 27 03:50:59 I am guessing you are a little high on the voltage? Dec 27 03:51:40 N2TOH: what are you expecting and actually getting. This thing is a swiss army knife for outputs :) Dec 27 03:53:08 I'm getting 275/350VDC for the switchable voltage, and about 820VDC for the high voltage. Dec 27 03:53:42 the filament voltage is 12 something, but still in spec Dec 27 03:54:07 820 is in spec Dec 27 03:54:20 but looks to drop fast with load. Dec 27 03:54:25 * N2TOH crap I thought I recorded my results someplace... Dec 27 03:55:07 yeah I'm not concerned with the HV or 820VDC specs, it's the selectable voltage that seesm high Dec 27 03:55:14 although 250ma at that voltage is a lot. Dec 27 03:55:37 the Heathkit docs reference 250VDC/300VDC Dec 27 03:56:37 well yeah this power supply commonly feeds a pair of 6146B+plus driver tube for about 120 Watts of RF output into a 50 Ohm load! Dec 27 03:58:12 keep in mind this is a power supply for many of Heathkits products, most of them were 90 < 100% tube based Dec 27 03:58:35 it does show 275 - 350 with no load Dec 27 03:58:52 AH! thank you!!!! Dec 27 03:59:09 so it will drop fast when it has some load and be fine. Dec 27 03:59:22 just be sure you are not hte load :) ouch. Dec 27 03:59:27 * N2TOH dumb dumb me! I forgot about that... Dec 27 04:00:06 yeah I almost forgot about that when making the test plug to bypass the AC switch Dec 27 04:00:46 the HP-23 has contacts to allow the load device to control the input power... Dec 27 04:01:27 N2TOH: check out my spectrum analyzer running off a BBB. ill pm it so it does not get trashed :) Dec 27 04:01:57 I'll have to reference the docs again as I have an SB-101, and an HX-1681 Dec 27 04:02:14 please send links, as I would like another SA Dec 27 04:06:08 its scanning that range so a licenses or unlicensed radio will show up when I test. Dec 27 04:07:23 I built a node.js addon module in C++ to talk to the scanner Dec 27 04:19:53 * Dr{Who} goes back to playing diablo III ttfn Dec 27 04:53:29 any timeline on production for BBB? Dec 27 04:54:18 are they out of stock or somethin? Dec 27 04:54:37 * Stoob is hecka outta the loop Dec 27 04:56:31 sorry dropped out. None of the Australian distributors seem to have BBB stock, nor Adafruit. Dec 27 05:05:54 <_av500_> new ones are being made every day Dec 27 05:05:59 <_av500_> in three shifts Dec 27 05:11:56 we just got a box of 20 in last week.. Dec 27 05:12:05 so, yeah, no supply chain problems of which I'm aware **** BEGIN LOGGING AT Fri Dec 27 06:01:12 2013 Dec 27 10:43:06 HI Dec 27 11:14:11 LO Dec 27 11:44:04 hi Dec 27 11:44:30 i am not able to connect BBB with usb cable to my PC Dec 27 11:44:40 what should be the problem Dec 27 13:08:26 hey, does anyone know what the output voltage of the beagleBone Black header pins are? Dec 27 13:14:39 either 1.8v or 3.3v, but the SRM knows for sure per pin. Dec 27 13:19:11 Anyone know what my Beaglebone doesnt boot when power is applied I need to hit the power button for it to turn on Dec 27 13:34:24 what power? Dec 27 13:34:28 usb or DCin? Dec 27 14:14:10 av500: DCin Dec 27 14:23:54 power button? Dec 27 14:56:12 Is it possible to emulate beaglebone? Dec 27 14:56:33 theoretically yes Dec 27 14:56:43 practically i dont know of anyone who did it Dec 27 14:56:50 why do you ask? Dec 27 14:58:31 good luck emulating PRU Dec 27 15:00:34 emulating PRU is not that difficult Dec 27 15:00:41 it's a very simple machine Dec 27 15:01:13 but then, if you want to have a complete, cycle exact emulation, then i wonder why you dont take the real thing... it's cheaper and less work too! :) Dec 27 15:10:03 KotH: cause i mounted the BBB in an enclosure and left it at work Dec 27 15:10:11 KotH: now i cant get it back and tomorrow is saturday so i cant get one :( Dec 27 15:10:25 tough luck ^^' Dec 27 15:11:23 i would recommend to enjoy your holiday and stay away from the computer for a while... go outside, do something with you family and friends, etc pp :) Dec 27 15:12:40 I hav a deadline on the 31st :"( Dec 27 15:12:50 maybe ill get a raspberry pi instead. Is it the same Processor core Dec 27 15:13:13 if it's just software you are doing, then you can run it on your pc as well Dec 27 15:13:25 interacting with the outside world is different though Dec 27 15:16:08 KotH: i am doing DSP.. and parameters need to be tweaked so it works on a less powerful comp like bbb Dec 27 15:16:33 hmm... Dec 27 15:16:55 you can do the same on the pc as well. just optimize it for lower cpu usage Dec 27 15:17:21 ofc unless you have a lot of assembly, but then you need exact the same hardware to test, even the rpi wont help much there Dec 27 15:18:29 I notice there is a qemu version of Beaglebone not black. do you think that can simulate its performance Dec 27 15:18:52 probably Dec 27 15:19:12 you can probably use qemu to simulate the arm-a8 core of the bbb as well Dec 27 15:19:26 i dont know how realistic the performance numbers of qemu are Dec 27 15:20:01 afaik it was optimized for simulation speed, not for being cycle exact Dec 27 15:20:50 zump: the rpi is not the same CPU core Dec 27 15:21:02 ARM11 vs Cortex A8 Dec 27 15:21:05 armv6 vs armv7 Dec 27 15:21:26 if you need to optimize ARM assembly, you dont need a BBB emulator Dec 27 15:21:45 you just need any ARM emulator with the same core Dec 27 15:22:11 "Qemu is not cycle accurate. There is no particularly meaningful way to translate between qemu performance and how fast something will run on real hardware." - mailing list guy :'( Dec 27 15:23:25 even if it was ... it would still depend on the hos CPU ... Dec 27 15:23:31 *host Dec 27 15:23:49 any arm dev boards using the same core as BBB? Dec 27 15:24:08 (imagine a 500MHz Celeron vs a 3GHz Xeon you run the VM on) Dec 27 15:24:21 zump: many Dec 27 15:24:30 beagleboard XM :) Dec 27 15:24:32 zump: the question is, can you get any of those Dec 27 15:25:20 Beaglebone 1 in stock.. but double the price.. damn you RS!! Dec 27 15:25:22 http://www.arm.com/products/tools/models/fast-models/ Dec 27 15:25:31 zump: its not RS Dec 27 15:25:37 it does cost more Dec 27 15:25:52 BBW was $89 or so Dec 27 15:26:01 WaaAa Dec 27 15:26:06 and why is this? unoptimized bom? Dec 27 15:26:19 different design criteria Dec 27 15:26:34 zump: smaller batches Dec 27 15:26:38 different BOM Dec 27 15:26:45 2ys earlier... Dec 27 15:26:46 etc.. Dec 27 15:26:56 also, Ferraris Dec 27 15:27:30 or use your N900 Dec 27 15:27:58 somebody should host BBBs in the cloud and rent them out Dec 27 15:28:19 make a kickstarter project for that :) Dec 27 15:28:24 +1 Dec 27 15:28:32 maybe they can dual boot too Dec 27 15:28:36 haha Dec 27 15:28:52 ogra_`: also, pls stop confusing with facts! Dec 27 15:28:58 lol Dec 27 15:29:02 sorry :) Dec 27 15:29:12 has anyone got that parallela board? Dec 27 15:29:54 zump: yes, this guy: http://a-hackers-craic.blogspot.de/ Dec 27 15:30:01 he wrote like 20 posts about it Dec 27 15:30:30 http://a-hackers-craic.blogspot.de/search/label/parallella Dec 27 15:30:33 26 in fact Dec 27 15:31:49 thats some low level stuff Dec 27 15:32:16 wish i had time to do this independent research Dec 27 15:33:08 dont look at it as research, but as a hobby and you will have time Dec 27 15:33:09 its about low level Dec 27 15:33:28 parallela wont run ubuntu faster by magic Dec 27 15:33:38 not?? Dec 27 15:33:53 * KotH throws his xmos boarda away Dec 27 15:33:58 wait, that was something different Dec 27 15:34:44 yeah but im supposing there would be some sort of api provided Dec 27 15:35:21 not just be like 'uh yeah, we've soldered a magic chip on there.. good luck!' Dec 27 15:35:35 err... Dec 27 15:35:44 parallela is a highly parallel computing environment Dec 27 15:36:03 it's a totally different architecture than a superscalar processor Dec 27 15:36:42 right Dec 27 15:36:46 there is no way "some sort of api" can magically convert a sequential program into something that scales into something parallel Dec 27 15:37:07 unless that sequential program was unoptimized crap Dec 27 15:37:37 if you want to know more about that kind of machines, i suggest you read "parallel computer architecture" by culler, singh, gupta Dec 27 15:38:14 ok Dec 27 15:39:37 http://openmp.org/wp/ ? Dec 27 15:39:51 that's a website Dec 27 15:40:10 or rather an url that leads to a website if loaded using a webbrowser Dec 27 15:40:11 1) print hardcopy of website Dec 27 15:40:16 2) place under CPU Dec 27 15:40:21 3) ...
