**** BEGIN LOGGING AT Fri Jul 05 02:59:58 2013 Jul 05 03:24:10 howdy howdy Jul 05 03:24:18 so i got a beaglebone black, I want to use the CAN Bus Jul 05 03:24:30 i'm assuming I need a transceiver? or can I just PnP? Jul 05 03:24:56 i.e: one of these -> http://www.ti.com/product/sn65hvd231 Jul 05 03:37:11 from a software developer's standpoint, is the AM37x different than the OMAP3530? Jul 05 03:37:28 or are the peripherals/memory layout identical? Jul 05 03:57:21 ok, i feel so stupid. Jul 05 03:57:28 i solved my ssh problme. Jul 05 03:58:30 emocakes: yeah you need a transceiver Jul 05 03:58:40 something that can work with the sitara's 3.3V levels too Jul 05 03:59:22 ...which that SN65HVD231 seems to fit the bill :) Jul 05 04:02:09 cheers Spirilis Jul 05 04:02:44 so im guessing if i wanted more CAN channels, i'd be able to connect them to the same can bus or would i need to communicate with them someway else Jul 05 04:03:40 uhm, I know each CAN channel on the sitara is a unique & separate bus Jul 05 04:04:11 i.e. each set of CAN+ and CAN- I/O pins on the beaglebone is a separate can channel Jul 05 04:04:29 it's kinda silly that it has more than 1 can channel but it's probably to interface with multiple independent systems at once Jul 05 04:04:33 sitara being "industrial" and all Jul 05 04:05:01 but yeah each channel is a bus that can handle tons of devices Jul 05 04:05:31 each with their own transceiver and CAN controller of some kind, tapped into the differential CANH/CANL lines Jul 05 04:07:23 good, I plan on interfacing with my car Jul 05 04:07:39 yeah I'm considering playing with that soon Jul 05 04:07:45 making it do stuff like lock my doors once travelling above 40km/h Jul 05 04:07:51 close my windows when i lock the car Jul 05 04:07:52 etc Jul 05 04:07:52 also going to play with microchip's MCP2515 for getting smaller microcontrollers on the CAN bus Jul 05 04:08:14 kinda want to open the door for using CAN as a universal comm link for microcontroller projects that are hardwired Jul 05 04:08:48 one thing I'm not totally sure about is what the exact voltage levels are, or whether it matters Jul 05 04:09:10 like automotive vs. other industrial stuff, from what I read most transceivers can work with a wide range of voltages but it's something I'm not quite clear on Jul 05 04:11:00 I have been meaning to check that out spirilis Jul 05 04:11:14 maybe a good book is what I need. Jul 05 04:11:20 i got a new oscilloscope which can be battery powered, so I'm going to sniff some of the canbus traffic this weekend Jul 05 04:11:25 nice Jul 05 04:11:27 what sort of car? Jul 05 04:11:37 mine's a Subaru Forester (2008) Jul 05 04:11:44 alrighty Jul 05 04:11:47 volvo v70 2001 Jul 05 04:11:54 t5 model Jul 05 04:11:57 vroom vroom Jul 05 04:12:15 I know on top of all the CAN data link layer crap there's a whole nother world of protocol and complexity, but I'll cross that bridge when I get there Jul 05 04:12:23 its good fun, i got the volvo diagnostics tool Jul 05 04:12:28 which allows you to control everything Jul 05 04:12:29 neat Jul 05 04:12:38 i.e: windows, door locks, abs brake solenoids, lights Jul 05 04:12:56 so i can send commands via that and then sniff it to get a clearer idea Jul 05 04:13:01 or what is what Jul 05 04:13:31 Hello KotH Jul 05 04:13:40 where are you ? Jul 05 04:13:42 hes not here Rocky Jul 05 04:13:44 go away Jul 05 04:13:50 hes not ur bitch Jul 05 04:13:54 hes mine Jul 05 04:14:16 Ok, I want borrow your bitch for a moment Jul 05 04:14:19 is that ok ? Jul 05 04:14:46 why i can;t connect to the irc server in my company network Jul 05 04:14:55 but i can connect it through webinterface Jul 05 04:15:05 come to think of it my Logic Analyzer (saleae logic16) has a CAN analyzer plugin that works with the CMOS/TTL level (data link layer, i.e. behind the transceiver) Jul 05 04:15:36 dont ask us rocky Jul 05 04:15:41 they probably block port 6667 Jul 05 04:15:44 jeeze Jul 05 04:15:55 does it really spirlils? Jul 05 04:16:09 great, i'll give that a whirl when i set up the transceiver Jul 05 04:16:16 i got a saleae 16 as well Jul 05 04:16:16 :p Jul 05 04:16:19 nice Jul 05 04:16:22 yeah the software has it in there Jul 05 04:16:48 ah i see Jul 05 04:17:05 where you amazed at how small it is? Jul 05 04:17:05 lol Jul 05 04:17:09 haha yes Jul 05 04:17:11 i thought id be getting a big box Jul 05 04:17:15 and then i had this little square Jul 05 04:17:17 and was like wtf Jul 05 04:17:19 I don't use it that often but it saves my ass every time Jul 05 04:17:30 do you work in this field? Jul 05 04:17:37 nope Jul 05 04:17:41 it's just a hobby Jul 05 04:17:58 what area you work in? Jul 05 04:18:24 general IT administrative stuff Jul 05 04:18:26 unix/linux/storage Jul 05 04:18:42 some software development but mostly on the admin side of the role Jul 05 04:18:57 i.e. sysadmin Jul 05 04:19:11 or BOFH Jul 05 04:20:07 ahh k Jul 05 04:20:14 <- developer / sysadmin here Jul 05 04:20:22 werd Jul 05 04:20:26 werd up Jul 05 04:20:27 :p Jul 05 04:21:26 lol well this book would probably cover what I need to know but I don't care to spend $101: http://www.amazon.com/Understanding-Controller-Network-Communication-Protocol/dp/1461403138/ref=sr_1_3?ie=UTF8&qid=1372997560&sr=8-3&keywords=controller+area+network Jul 05 04:27:33 ah this looks nicer, even mentions the MCP2515: http://www.amazon.com/Controller-Network-Projects-Dogan-Ibrahim/dp/1907920048/ref=sr_1_1?ie=UTF8&qid=1372997560&sr=8-1&keywords=controller+area+network Jul 05 04:29:20 Spirilis Jul 05 04:29:21 http://www-inst.eecs.berkeley.edu/~ee249/fa08/Lectures/handout_canbus2.pdf Jul 05 04:29:45 <3 Jul 05 04:33:27 ah I see, range is -2 to +7V in theory Jul 05 04:33:57 but really probably can be whatever the hell you want, so long as there's a certain minimum difference between the H and L Jul 05 04:35:31 alright meanwhile bedtime Jul 05 04:35:31 bbl Jul 05 04:41:07 bai Jul 05 04:54:37 hhee Jul 05 04:54:48 slaa Jul 05 04:56:01 v Jul 05 04:57:50 w Jul 05 04:58:02 hello Jul 05 04:58:06 echo Jul 05 04:58:36 i hav a query Jul 05 04:59:00 i have a piece of bread Jul 05 05:00:48 i cant insert module in beagleboard xm Jul 05 05:01:38 showing error invalid module format Jul 05 05:02:12 then the module does not match the kernel Jul 05 05:02:29 just wait Jul 05 05:02:58 I have all day Jul 05 05:03:09 how can i switch to log channel using IRC client Jul 05 05:03:10 ? Jul 05 05:03:23 av500, any advices? Jul 05 05:03:46 ? Jul 05 05:03:52 in your client Jul 05 05:03:55 there is a setting Jul 05 05:03:59 to log the channel Jul 05 05:04:03 it depends on the client Jul 05 05:04:20 also, you need to stay online of course Jul 05 05:04:28 if you leave, no more logs Jul 05 05:04:38 but I think there are logs of #beagle somewhere too Jul 05 05:04:47 i hav a beagle board running in angstrom linux 2.6.30 Jul 05 05:05:32 HEELO Jul 05 05:05:37 yes Jul 05 05:05:39 we hear you Jul 05 05:05:53 I can not understand what you said Jul 05 05:06:02 IIRC the url mentioned in the topic here has links to two sets of channel logs. Jul 05 05:06:43 RockyZheng: as much as I like to help you, it feels like to much hand holding to me Jul 05 05:07:15 aa Jul 05 05:07:32 I feel like you dont google/baidu stuff before you ask here Jul 05 05:07:41 lazy Jul 05 05:07:44 boy Jul 05 05:07:45 I am Jul 05 05:13:52 av500, done, I have solved this problem,s Jul 05 05:13:58 good Jul 05 05:14:57 I just use command [find . -iname 'freenode*'] to find the local log file. Jul 05 05:16:02 what client are you using?

Jul 05 05:28:28 hi there Jul 05 05:29:02 I'm using a BB xM C2 board with angstrom linux 2.6.323 Jul 05 05:29:08 sorry 2.6.32 Jul 05 05:29:51 i'm not able to insert the driver module compiled ... what will be the problem Jul 05 05:30:17 how did you compile it? Jul 05 05:30:48 I'm using the arm-none-linux-gnueabi toolchain Jul 05 05:32:13 hi Jul 05 05:32:25 I downloaded a 2.6.32 src code from kernel.org and compiled using thr make omap3_beagle_defconfig command Jul 05 05:32:38 hi john Jul 05 05:33:10 where can i get the source for Kernel Linux 3.2.0-23-generic-pae Jul 05 05:33:45 john___: apt-get source 3.2.0-23-generic-pae Jul 05 05:34:05 john___: but that's not really a beagle question Jul 05 05:34:31 i want to compile driver for beagle xm Jul 05 05:34:41 oh.. by the way: HAPPY FRIDAY EVERYONE! Jul 05 05:35:16 ok Jul 05 05:35:19 john___: then you dont want to get a ubuntu kernel Jul 05 05:35:58 I'm using a BB xM C2 board with angstrom linux 2.6.32 Jul 05 05:35:58 john___: download either the 3.2.x from kernel.org, or if you have a working kernel already, the sources of the guy who compiled it Jul 05 05:36:18 where is av500? Jul 05 05:37:50 he isn't up (or moving) as he hasn't ruined my sleep with terrible images. Jul 05 05:38:19 I have compiled using the arm-none-linux-gnueabi toolchain Jul 05 05:38:32 KotH-i have downloaded 3.2.0 and compiled but while inserting it shoen invalid module format Jul 05 05:38:58 john___: kernel and module have to be compiled the same way Jul 05 05:39:13 john___: any deviation in toolchain or configuration and it wont work Jul 05 05:39:34 john___: so you are probably using a kernel someone else compiled with your self-compiled module Jul 05 05:40:05 ka6sox: dont worry, it's friday and av500 will deliver ;) Jul 05 05:43:28 Src: that does not work Jul 05 05:43:35 ah, koth said it already Jul 05 05:43:51 why? Jul 05 05:43:56 ka6sox: you will be spared for a fortnight Jul 05 05:44:34 fortnight. how... archaic. Jul 05 05:44:43 av500: why it is not working? Jul 05 05:45:09 av500: I have compiled the modul for 2.6.32 downloaded from kernel.org Jul 05 05:45:28 http://linux.die.net/lkmpg/x380.html Jul 05 05:46:08 if you made the effort to simply google for "Invalid module format" Jul 05 05:46:16 KotH-i have compiled kernel and module with arm-angstrom-linux-gnueabi-gcc Jul 05 05:46:17 ... Jul 05 05:46:29 can you keep one nick? Jul 05 05:46:38 or do you have a split personality? Jul 05 05:51:09 av500, ORLY? they don't have internet in France? Jul 05 05:51:37 (I know they don't have the formula for Ice) Jul 05 05:51:52 av500: the board has angstrom linux 2.6.32 but the downloaded src from kernel.org Jul 05 05:52:13 ka6sox: they have Jul 05 05:52:21 Src: exactly Jul 05 05:52:28 Will this be the problem for version mismatch? Jul 05 05:52:31 why dont you google and read a bit Jul 05 05:52:32 yes Jul 05 05:55:45 av500:cp /boot/config-`uname -r` /usr/src/linux-`uname -r`/.config. What this cmd is actually doing? Jul 05 05:56:11 try uname -r Jul 05 05:56:16 and you will see Jul 05 05:57:33 av500: that's right Jul 05 06:02:40 I have used the same command to know the version of kernel in board.its showing 2.6.32 Jul 05 06:03:53 av500: and in the module which i have buit for testing... also tells that its 2.6.32 Jul 05 06:04:15 yes Jul 05 06:04:25 it still has to to be the exact same kernel Jul 05 06:04:28 from the same souce Jul 05 06:04:30 source Jul 05 06:05:14 I dont have the source code of the board as It was shipped with the image files only Jul 05 06:07:36 the code is there Jul 05 06:07:40 Src, demand the source Jul 05 06:07:47 its angstrom Jul 05 06:07:50 angstrom.org Jul 05 06:08:06 :one more doubt... Jul 05 06:08:07 er Jul 05 06:08:25 http://www.angstrom-distribution.org Jul 05 06:08:56 oh, then the source is there (I saw it an hour ago) Jul 05 06:09:10 might be a bit tricky to get to the .32 one Jul 05 06:09:25 or is that still current for XM? Jul 05 06:10:00 will the src code downloaded from kernel.org for 2.6.32 and that the one in Board different (as it shows 2.632 on typing uname-r command ) Jul 05 06:10:08 yes Jul 05 06:10:21 one is mainline, one is "patched" Jul 05 06:10:27 same version, but different code Jul 05 06:10:32 thus the module mismatch Jul 05 06:11:50 av500: ok... Jul 05 06:14:13 av500: but there should have been some difference in 'EXTRAVERSION ' ...right? Jul 05 06:15:43 maybe Jul 05 06:19:58 I think i need to install some stuffs for kernel using open embedde Jul 05 06:22:48 yes Jul 05 06:22:58 its a bit heavy process if all you want is the kernel Jul 05 06:23:34 koen: is the github kernel also for XM? Jul 05 06:23:40 3.8 too? Jul 05 06:34:52 av500: you know how t get the kernel src code ? Jul 05 06:36:27 <_Sy_> Good morning Jul 05 06:36:49 lol, matroshka caps: http://diy-fever.com/misc/fake-capacitors/ Jul 05 06:36:58 fake cap inside a fake cap Jul 05 06:37:32 av500: the beagle* branches are for xM Jul 05 06:37:39 av500: the 3.11 branch will for for xM in the future Jul 05 06:37:46 3.8/3.9 are a disaster on x< Jul 05 06:37:47 M Jul 05 06:37:55 it doesn't work with DT Jul 05 06:38:00 and it doesn't work without DT Jul 05 06:38:05 koen: the silicon vendor oughta do something about it!!! Jul 05 06:39:15 * ka6sox is glad he has his boots on Jul 05 06:39:39 av500: the ex-WTBU guys have been doing great with DT support for classic and xM Jul 05 06:40:15 koen: trying to detect sarcasm Jul 05 06:40:15 Roger Quadros has been steadily improving the DT files Jul 05 06:40:24 or real praise Jul 05 06:40:27 not sure :) Jul 05 06:40:28 real praise Jul 05 06:40:33 oh wow Jul 05 06:40:51 and a dig at the sitara people for not doing anything productive as usual Jul 05 06:41:07 I guess they are on hold, pending a rename Jul 05 06:41:21 that name has been in use way to lonf Jul 05 06:41:23 long Jul 05 06:43:30 I also have sgx sources now Jul 05 06:43:50 just need to find the time to try and build them against the drm drivers for omap3 and am335x Jul 05 06:44:41 this tight coupling between 3d drivers and linux video stack of the day is annoying Jul 05 06:45:17 not so much linux video stack as vendor display drivers Jul 05 06:45:36 am335x doesn't compile because it depends in TI extensions to the driver which aren't in mainline Jul 05 06:50:16 xm is 3730? Jul 05 06:50:19 yes Jul 05 06:50:32 aka omap3, take 2 Jul 05 06:50:41 the "make it work" version Jul 05 06:50:50 they almost succeeded Jul 05 06:51:06 I started out in fake OMAP3...3430 Jul 05 06:51:23 nobody talks about 3430 any more Jul 05 06:51:31 or its civilian sibbling 3530 Jul 05 06:51:47 right...swept under the carpet Jul 05 06:51:52 "one of these days well look back on this, laugh nervously and change the subject" Jul 05 06:52:00 removed like all the people around stalin Jul 05 06:52:08 emeb_mac, +1 Jul 05 06:52:12 +1 Jul 05 06:52:13 or even the early 3430 silicon in certain products ;) Jul 05 06:52:27 they did look at me kind of sideways when we had one going 1.1Ghz Jul 05 06:52:31 the really cool products had 3440 Jul 05 06:53:41 I got my first 4460 and then the announcement...p00f Jul 05 06:54:11 3430, 3440, 3730, 4430, 4460, 4470 Jul 05 06:54:17 btdt Jul 05 06:54:35 no tshirt Jul 05 06:54:41 3430,3530,3620,4430,4460 Jul 05 06:54:44 bummers Jul 05 06:54:57 20 is the dsp less?

Jul 05 09:39:55 it's one of the days one ought to remember, if you are a member of the alliance Jul 05 09:40:05 but becide that? Jul 05 09:40:08 beside Jul 05 09:40:24 61 years since the birth of the transistor Jul 05 09:40:36 so ka Jul 05 09:40:39 shiranakatta! Jul 05 09:40:40 William Shockley and the Bell Labs Jul 05 09:40:59 and now look what we did with them Jul 05 09:41:03 we've made dog computer Jul 05 09:41:22 a whole family of those too! Jul 05 09:41:33 next we'll send them to space! Jul 05 09:41:37 and fruit Jul 05 09:42:03 we send them fruit? Jul 05 09:42:23 apples, blackberrys, and raspberrys Jul 05 09:42:33 a dog in space does not want fruit Jul 05 09:42:34 there was an apricot Jul 05 09:43:12 many went pear shaped Jul 05 09:45:16 av500: did you ever work with LPMx.5 on the msp?

Jul 05 09:45:54 all I did was blink leds Jul 05 09:46:10 soon I will step steps Jul 05 09:46:14 av500: sending the msp into eternal slumber, where even the RAM and registers lose power Jul 05 09:46:27 only to be left by a POR Jul 05 09:46:28 I do that by pulling the plug Jul 05 09:46:42 i'm old Jul 05 09:46:53 i know Jul 05 09:47:01 your kids are old enough to have kids themselves Jul 05 09:47:40 which thread Jul 05 09:48:32 the one on the right side of your shirt Jul 05 09:49:34 dangling* Jul 05 09:50:20 It is possible to generate a PPM Signal with the Beaglebone? Jul 05 09:50:47 what is a PPM signal? Jul 05 09:50:53 Pulse position modulation Jul 05 09:51:06 Pulse per Minute? Jul 05 09:51:21 Exactly what the answer is depends on the details. Jul 05 09:51:47 But, the PRUs can do it unless it's really, really complex. Jul 05 09:51:48 SpeedEvil: so, my answer then will be "maybe" Jul 05 09:52:09 spbaum: my consdiered answer is "maybe". but if you give us some mroe detail. Jul 05 09:53:17 Ok... i want to calculate 8 pwm channels into one ppm signal Jul 05 09:53:50 You mean you want to generate a servo waveform? Jul 05 09:53:54 To go to a transmitter? Jul 05 09:55:56 yes Jul 05 09:57:11 [ 0.091494] CPU: Testing write buffer coherency: failed, unable to map memory Jul 05 09:57:23 life in the fscking bleeding edge Jul 05 09:58:27 spbaum: The question is severalfold yes. A) The PRUs can do it trivially. B) It may be possible to do it with the PWM units, if they are flexible enough. C) DMA is another possible option. Jul 05 09:58:28 SpeedEvil: PWM and a monoflop? Jul 05 09:58:45 er spbaum Jul 05 09:59:21 av500: It's not that simple. You have servo waveorms. These are 20ms interval, between 0.5 and 1.5ms high - or so. Then you interleave these together - 8 or so, at 2ms spacing, leaving a gap Jul 05 09:59:34 each pulse width can vary Jul 05 09:59:45 beaglebone recives mutiple servo commands over wifi and transmit it over ppm to a controlling board Jul 05 09:59:47 Of course, there is D) bit-bang in sotware. But this sucks. Jul 05 10:00:34 And e) use an interrupt to reconifigure the PWM unit at ~1khz Jul 05 10:00:49 SpeedEvil: if pulse width varies, it's pwm, no? Jul 05 10:00:50 not ppm Jul 05 10:01:14 av500: technically Jul 05 10:01:20 use dma to reconfigure pwm Jul 05 10:01:30 mru: Oh - that'd work better Jul 05 10:01:40 f) then Jul 05 10:02:07 err, there is a hardware module on the am335x especially for driving motors Jul 05 10:02:07 g) DMA to a serial port, low-pass filter, and then schmitt trigger. Jul 05 10:02:16 h) use that. Jul 05 10:02:18 :) Jul 05 10:02:43 difficulty, there's no driver :) Jul 05 10:02:51 The motor driving module may not be able to do that sanely though Jul 05 10:02:58 It's not really a 'motor' waveform Jul 05 10:03:00 (eQEP) Jul 05 10:03:03 panto: no need for driver Jul 05 10:03:04 i) poke it with a pointy stick Jul 05 10:03:10 there is always /dev/mem Jul 05 10:03:15 j) stick your d**k in it Jul 05 10:03:16 mru: That's d) Jul 05 10:03:28 heh Jul 05 10:03:37 equivalent to i, but with less reach Jul 05 10:03:40 you can also use audio out Jul 05 10:03:55 it will at least sound good Jul 05 10:04:02 or lcd out Jul 05 10:04:13 hdmi can get tricky Jul 05 10:04:34 lcd should be fine Jul 05 10:04:53 can we have 0 sized porches? Jul 05 10:05:01 as in, pixels all the time? Jul 05 10:05:31 or does the electron ray that scans SDRAM need time to return? Jul 05 10:05:48 av500, it does Jul 05 10:05:53 hysterical raisins Jul 05 10:06:27 early tube based omaps? Jul 05 10:06:55 omap0.1 Jul 05 10:09:07 speedEvil you think with a it is possible Jul 05 10:33:00 they should rename kickstarter to 3dprinterstarter Jul 05 10:35:58 PRUs can indeed do it trivially - they're very fast microcontrollers. Jul 05 10:36:07 There may be easier ways Jul 05 10:36:44 "there may be easier ways" is kinda implied when PRU is mentioned Jul 05 10:37:31 That was basically the nuclear option - when the problem wasn't defined. Jul 05 10:50:23 if pru is the nuke, where is the orbit? Jul 05 10:54:41 Hi I have a question that I hope someone can help me with. I have a beagleboard black and are trying to install different OS on it but I get stuck at the same point everytime. If I understand it correctly u-boot should send some text on the serial communication port but I can't open any connection to listen to the communication. When I run Angstrom OS I get a port in realterm but it is never showing up when I try to boot another OS on Jul 05 10:56:00 Should I be able to listen to serial communication from u-boot? The reason I am asking is that both startware OS and QNX mentions that I should be able to get some information or send commands through serial communication Jul 05 10:56:53 have you connected a serial cable to the single row pin header? Jul 05 10:58:10 J1, 6 pins Jul 05 11:12:15 av500: being your own community now? Jul 05 11:12:23 "page" Jul 05 11:12:28 it Jul 05 11:12:32 http://penny-arcade.com/comic Jul 05 11:12:33 it's a "page" Jul 05 11:12:39 seems appropriate for this channel Jul 05 11:12:45 av500: being sileced for overtrolling? Jul 05 11:12:53 av500: silenced? Jul 05 11:12:58 I see your posts Jul 05 11:13:07 even the ones with porn links Jul 05 11:13:09 silence of the lambs Jul 05 11:13:22 mru: yeah same here Jul 05 11:13:43 oh, well, last post from yesterday 10pm Jul 05 11:14:05 mru: silenced, not eradicated Jul 05 11:14:32 cunning scheme of his really, post a comic-style pic with a link to a cat picture hidden in a porn site Jul 05 11:17:41 hello Jul 05 11:21:58 av500: in what manner have you been 'silenced'? Jul 05 11:23:19 my icon shows it Jul 05 11:23:49 i'm mute Jul 05 11:24:11 you're not making sense Jul 05 11:24:26 I cannot post Jul 05 11:24:28 or comment Jul 05 11:24:32 they took off and muted him from orbit Jul 05 11:24:36 +1 Jul 05 11:24:46 since when? Jul 05 11:24:50 this night Jul 05 11:24:53 you posted plenty yesterday Jul 05 11:24:59 I have a friendly email to tell me so Jul 05 11:25:04 oh Jul 05 11:25:09 you said something about weeks Jul 05 11:25:14 yes Jul 05 11:25:17 *for* 2 weeks Jul 05 11:25:20 not since Jul 05 11:25:42 what did you do? Jul 05 11:25:56 he didn't think of the children Jul 05 11:26:09 mru: I wont discuss that here Jul 05 11:26:15 see, we need those porn filters Jul 05 11:26:33 but lets say ka6sox-away could not sleep for weeks Jul 05 11:26:36 someone silenced av500 ? Jul 05 11:26:46 move to iran, they finally realised filters don't work Jul 05 11:27:00 they work Jul 05 11:27:05 not the technical ones Jul 05 11:27:16 its the psychological ones Jul 05 11:27:19 the shoot-on-the-spot ones do Jul 05 11:27:26 that too Jul 05 11:27:30 and the fear of that Jul 05 11:27:35 fear works Jul 05 11:27:49 it's curious though that even though facebook is banned, they used it in the election campaigns Jul 05 11:27:57 clearly they know people are using it regardless Jul 05 11:28:11 of course Jul 05 11:28:22 but you know Jul 05 11:28:29 if using it makes you suspicious Jul 05 11:28:35 let everybody use it Jul 05 11:28:42 then you can use it against everybody Jul 05 11:36:24 and then there are countries, that dont even need that Jul 05 11:50:33 hi, when trying to play audio over hdmi on my BBB it doesn't work. That's the output: http://pastebay.net/1245598 Jul 05 11:50:56 it seems as if the music would be played but you can't hear anything Jul 05 11:51:22 mixer channels muted? Jul 05 11:51:31 I don't know how to mute/unmute them Jul 05 11:51:36 alsamixer? Jul 05 11:51:40 when starting "alsamixer" there aren't any channels Jul 05 11:51:49 hmm Jul 05 11:52:10 I haven't tried it myself so I don't know what it's supposed to look like Jul 05 11:52:52 http://i.imgur.com/roCavE8.jpg Jul 05 11:53:13 That's what it looks like. Jul 05 11:53:51 how can there even be no channels at all? Jul 05 11:56:02 if there is no mixer, there are no channels Jul 05 11:56:18 I wasn't sure how alsa presents such a situation though Jul 05 11:56:26 jacki3333, cat /sys/dev/bone_capemgr*/slots Jul 05 11:56:40 check which hdmi cape is loaded Jul 05 11:56:44 it could have faked a single master channel with at least a mute control Jul 05 11:57:00 panto: are there supposed to be mixer channels visible? Jul 05 11:57:02 and boot with drm.debug=255 to see if there's audio support Jul 05 11:57:12 there's no mixer Jul 05 11:57:20 cause there is no volume control on the hdmi Jul 05 11:57:26 of course not Jul 05 11:57:36 but a sw mute would be trivial enough Jul 05 11:57:50 I can't recall Jul 05 11:57:51 and alsa likes faking things Jul 05 11:57:54 there might be Jul 05 11:57:55 there's no /sys/dev/bone_capemgr* Jul 05 11:58:08 only /sys/dev/block and /sys/dev/char Jul 05 11:58:21 I'm using debian, I should have mentioned perhabs Jul 05 11:58:24 *ps Jul 05 11:58:27 err, /sys/devices Jul 05 12:01:07 excuse me, for some strange reason my WLAN today works like shit Jul 05 12:01:22 have you gotten my output? Jul 05 12:01:26 http://pastebay.net/1245600 Jul 05 12:02:27 ok, boot with an angrom fs too Jul 05 12:02:37 I can't debug any issues with debian Jul 05 12:02:53 mhm. Jul 05 12:03:37 I'd really like to use angstrom for that reason, but it isn't able to start up with a fixed IP Jul 05 12:03:49 unlike debian Jul 05 12:03:57 I'm sure you can configure it Jul 05 12:04:06 debian is more familiar to you that's all Jul 05 12:04:17 configured /etc/network/interfaces which is the debianoid way of doing this Jul 05 12:04:36 and also the angstrom way, as I have found in many tutorials Jul 05 12:04:43 but it just gets ignored Jul 05 12:05:35 also the busybox binaries of angstrom are incompatible to the standard utils which you can see when using "date" Jul 05 12:05:57 hi Jul 05 12:06:09 "date -s" expects a very other syntax than the default GNU/Linux version of date Jul 05 12:06:41 you can install the standard utils no? Jul 05 12:07:20 I can't even connect properly cause I can't configure networking Jul 05 12:07:50 because in every tutorial it says things like "configure /etc/network/interfaces as you are used to do in debian" Jul 05 12:08:00 http://www.gigamegablog.com/2012/02/06/beaglebone-linux-101-assigning-a-static-ip-address-with-connman/ Jul 05 12:08:27 LOL Jul 05 12:08:52 in that blog I found one of the tutorials he is now speaking of Jul 05 12:08:54 thank you Jul 05 12:09:21 does this not work? Jul 05 12:10:11 I will have to flash Angstrom to a SD card at first place Jul 05 12:10:19 but thx for now Jul 05 13:37:54 KotH, How to save tmux's session in case linux crash or power down so that I can restore tmux to its last status when system is powered up? Jul 05 13:41:49 RockyZheng: RTFM Jul 05 13:42:06 KotH, what is RTFM Jul 05 13:42:12 read the fucking manual Jul 05 13:42:35 Ok, you are not god Jul 05 13:42:40 :) Jul 05 13:43:36 nothing to do with god Jul 05 13:43:42 but as you said, you are lazy Jul 05 13:43:46 and we are lazy too Jul 05 13:43:55 and we can outlazy you by quite a bit Jul 05 13:44:49 not to forget that we have much more and better chocolate than you do Jul 05 13:46:04 and i dont want to be god, too much responsibility Jul 05 13:46:50 KotH: the current one doesn't seem too responsible :/ Jul 05 13:47:03 few dudes and dudettes would use some smiting Jul 05 13:47:37 KotH: Think of it, everybody would hate you and they'd have nothing they could do Jul 05 13:48:26 is there something like narcissus for other architectures ? Jul 05 13:48:40 what other? Jul 05 13:49:19 atom Jul 05 13:49:25 x86 Jul 05 13:50:03 yup Jul 05 13:50:13 maybe once minnowboard ships Jul 05 13:50:21 and ARM starts to peter out Jul 05 13:50:48 das: I guess narcissus itself is open source Jul 05 13:50:55 all you need is a PC to run it :) Jul 05 13:51:04 :D Jul 05 13:51:15 the thing is, I have a buildroot from Intel Jul 05 13:51:26 but it's such a pain to add new packages Jul 05 13:51:40 and you think adding packages to OE is easier? Jul 05 13:52:46 I dunno; I'm willing to try something else ... I wrote a script to integrate new packages to what Intel gave us but I still need to modify a Makefile per package Jul 05 13:53:04 so 1-2 packages is alright; a bunch is just redhibitory Jul 05 13:53:10 oh well Jul 05 13:53:19 I added a few myself here Jul 05 13:53:33 most is copy a template file and change a few strings Jul 05 13:54:06 meh; I need to copy from/to /sbin /bin /usr, /lib etc ... Jul 05 13:54:26 so I need to think for each package Jul 05 13:55:37 that the install tagret of most packages Jul 05 13:56:47 could you please advice some beaglebone-like embedded hardwares for study? Jul 05 13:57:06 already done with the beaglebone? Jul 05 13:57:08 bored? Jul 05 13:57:30 no no no Jul 05 13:57:38 so, stay with us :) Jul 05 13:57:50 nothing to do with beaglebone Jul 05 13:58:26 I want to know all the kinds of beaglebone-like hardware Jul 05 13:58:39 maybe I will buy some. Jul 05 14:00:37 av500, how old are you? Jul 05 14:00:45 old Jul 05 14:01:12 don't be mystery Jul 05 14:01:13 What is meant by "beaglebone like"? Jul 05 14:01:28 There's always Raspberry Pi, Cubieboard, etc. Jul 05 14:01:33 tons Jul 05 14:01:36 MarsBoard, Olimex... Jul 05 14:01:37 Etc. Jul 05 14:01:43 small low-cost embedded device for study Jul 05 14:01:56 RockyZheng: buying random boards is not much help Jul 05 14:02:02 study one in depth Jul 05 14:02:05 you'll learn more Jul 05 14:02:19 good advices Jul 05 14:02:29 after you have done one, you'll find they are all the same :) Jul 05 14:02:39 Yeah, and if its for study, it doesn't even matter which one to get. If you have specific usecases in mind, there are some differences that need to be taken into account. Jul 05 14:02:47 actually, i want to know all kinds of this low-cost hardware, won't buy it Jul 05 14:03:00 Like for instance, the BBB is not a good solution for a media center device. Jul 05 14:03:03 http://animalboard.org/ Jul 05 14:03:42 http://eda360insider.wordpress.com/2012/06/26/39-low-cost-boards-for-embedded-linux-application-development-starting-with-raspberry-pi-want-the-list/ Jul 05 14:05:12 so detailed list Jul 05 14:05:14 thanks Jul 05 14:05:24 av500, nice people Jul 05 14:05:38 that is what i want Jul 05 14:05:49 dont thank me :) Jul 05 14:06:17 http://www.baidu.com/s?wd=low+cost+embedded+boards Jul 05 14:10:20 av500: you suddenly changed your search engine preferences? ;) Jul 05 14:13:08 av500: that 39 list is kinda incomplete/out of data now, isn't it? I mean, cubie, odroid, wand - and the ARM9 stuff, seriously... ;) Jul 05 14:14:06 kfoltman: I have seen promote ARM9 boards at an electornic fair some months ago Jul 05 14:14:11 depending on the use case, why not Jul 05 14:15:20 will be interesting what comes out of the A5 corner though Jul 05 14:15:29 av500: I guess the performance/cost or performance/power isn't that good for ARM9, comparing to lower-clock ARMv7? Jul 05 14:16:57 dm8tbr: what do you mean? Jul 05 14:17:15 I think bradfa started playing with a SAMA5D3 based board recently Jul 05 14:18:39 kfoltman: the core is meant to replace ARMv6 Jul 05 14:18:59 these "cheap embedded boards" are basically the porn stars of electronics Jul 05 14:19:08 the majority of "boards" is plain and boring Jul 05 14:19:10 so I'd expect to see it in cheap chinese phones and in cheap embedded boards Jul 05 14:20:05 FPU optional, SIMD optional, sounds like limited use stuff Jul 05 14:20:24 because your washing machine needs an FPU? Jul 05 14:20:48 av500: I think the washing machine might not need anything better than 8-bit AVR :P Jul 05 14:21:41 automatic washing machine Jul 05 14:21:45 but, yes, a cheap phone perhaps - but I wonder if the price reduction is worth the functionality reduction Jul 05 14:21:53 we can control it through our mobile app Jul 05 14:22:05 kfoltman: can you imagine somethone *between* said machine and your smartphone? Jul 05 14:22:12 "Hai guise, can you help me run opencv on my washing machine?" Jul 05 14:22:34 it can detect green Jul 05 14:22:41 thats for sure Jul 05 14:23:10 av500: sure, but is that market THAT price-sensitive? Jul 05 14:23:27 no idea Jul 05 14:23:31 I dont know all the markets Jul 05 14:23:51 still there are use cases that might not need an FPU Jul 05 14:37:17 av500, where are you from? Jul 05 14:37:39 Frankfurt Jul 05 14:39:20 I like your country football team Jul 05 14:39:47 not into football Jul 05 14:39:58 why? Jul 05 14:40:08 do I have to? Jul 05 14:40:19 ok,skip it Jul 05 14:40:48 not into sports I would not play myself Jul 05 14:40:57 one word: too much running :) Jul 05 14:42:14 too much foot Jul 05 14:42:29 and too much ball Jul 05 14:44:02 ball is fine Jul 05 14:44:44 playing with balls... Jul 05 14:44:56 dm8tbr: soldering a Sitara again? ;) Jul 05 14:45:20 * dm8tbr hasn't done any real BGA soldering, ever Jul 05 14:45:48 I only once tried to resolder a wifi card that seemed to have developed a fault and it even sort of worked for a bit Jul 05 14:54:39 i once watched someone desoldering a 1000 pin BGA and soldering in a new chip... in 5 minutes Jul 05 14:54:42 and it worked Jul 05 14:54:59 must have been a robot Jul 05 14:55:06 he wasnt Jul 05 14:55:17 are you sure? Jul 05 14:55:20 rebot-like man Jul 05 14:55:21 and yes, that was the moment, when i found enlightenment Jul 05 14:55:37 yes, i turing tested him Jul 05 14:55:37 they can be very convincing Jul 05 14:55:40 well if you don't need to reball the chip and put it back, it shouldn't take thaaat long Jul 05 14:56:00 reballing sounds painfull Jul 05 15:02:02 train security just detained some dude Jul 05 15:02:26 for drawing a picture of a gun? Jul 05 15:11:11 dear $DEITY ... OSGI for the unique sake of controlling ZigBee, kill me now Jul 05 15:15:26 hello Jul 05 15:16:23 that's very polite of him Jul 05 15:19:20 * ka6sox-away slowly moves away from das as he is afraid $DEITY will kill him and ka6sox-away will become collateral damage Jul 05 15:20:49 -ENOTENOUGHSLEEP Jul 05 15:21:38 ka6sox-away: welcome to the club ;) Jul 05 15:26:26 florian, you have children too? Jul 05 15:26:27 :) Jul 05 15:27:43 ka6sox: yes... Jul 05 15:27:51 ka6sox: as well as a small company, an old house, and an old car... Jul 05 15:28:38 florian, we can commiserate :>( Jul 05 15:29:21 the car just turned over 300,000kms a week ago Jul 05 15:29:38 ka6sox: :-) Jul 05 15:30:03 that's not too bad... Jul 05 15:31:05 I have tried my best to dig out the way that how does linux kernel(embedded or not) load a filesystem, but failed, I can't find any materials or books that make me have better understand on question. any advices? Jul 05 15:31:32 KotH, how about your options about this question Jul 05 15:31:45 av500, what do you think? Jul 05 15:32:22 hi guys Jul 05 15:32:32 im looking for a good field monitor for the beagleboard black Jul 05 15:32:39 what are some options? Jul 05 15:34:00 florian, 50% of them are offroad miles. Jul 05 15:34:14 in 4 wheel drive... :( Jul 05 15:34:29 RockyZheng: file systems are not loaded Jul 05 15:34:31 they are mounted Jul 05 15:34:39 RockyZheng: http://unixbhaskar.wordpress.com/2010/03/19/insight-into-gnulinux-boot-process/ ? Jul 05 15:34:43 RockyZheng: read "the design of the unix operating system" by bach Jul 05 15:35:02 deller: monitor as in LCD screen? Jul 05 15:35:23 load = mount Jul 05 15:35:40 in that sentence Jul 05 15:35:49 yea Jul 05 15:35:51 ka6sox: sounds like you have an interesting way to work... Jul 05 15:37:57 florian, :)...I need Mr. Fusion and a flying car...it would be easier on my Kidneys Jul 05 15:39:36 go to sleep Jul 05 15:39:47 bye-bye, guys Jul 05 15:40:05 nitey nite RockyZheng Jul 05 15:58:28 Stupid question that I can't find in the doc's. I can load a cape with echo "xx" > /sys/devices/bone_capemgr.9/slots manually, how can I do it at boot? Jul 05 16:00:25 how can i get analog video output from the beaglebone black? Jul 05 16:01:27 or even DSI for that matter Jul 05 16:01:57 jmoyerman, put capemgr.enable_partno=XXX in your kernel cmd line Jul 05 16:02:07 deller, no, you can't without external h/w Jul 05 16:02:19 i know Jul 05 16:02:22 which capes do it Jul 05 16:02:26 and how good are they? Jul 05 16:02:33 AFAIKT no cape has analog video out Jul 05 16:02:37 panto: d'oh so simple... thank you greatly. trying to get the dvi-d audio cape listening/playing music Jul 05 16:02:54 and DSI? Jul 05 16:02:56 some insane dude managed to get it via the PRU and a resistor lader Jul 05 16:02:59 *ladder Jul 05 16:03:06 That sounds painful. Jul 05 16:03:31 deller: Off-the-shelf HDMI-to-analog adapters are easiest. Jul 05 16:03:55 yea but i might as well buy an hdmi screen Jul 05 16:04:02 VGA via resistor ladder is possible, but crazy. Jul 05 16:04:07 I mean, really Jul 05 16:05:01 has anyone used the beaglebone LCD3 or LCD4 from beagleboardtoys.info Jul 05 16:05:26 * jkridner wonders what's inside http://www.ayagroup.com/product.php?productid=19426&gclid=CO7tnNDdmLgCFSUV7AodpRsArQ Jul 05 16:05:31 I've used both. Jul 05 16:05:34 and LCD7 Jul 05 16:05:42 how are they? Jul 05 16:05:55 good... Jul 05 16:05:56 a bit on the pricey side no? Jul 05 16:06:01 yeah... Jul 05 16:06:08 are there non touch versions? Jul 05 16:06:19 slightly high on price and the built-in distro doesn't have a great UI for 3" and 4" LCDs... Jul 05 16:06:30 but, you can run things full screen effectively. Jul 05 16:07:00 touch is resistive, which is handy for using a stylus, but it can be tough clicking stuff in corners... Jul 05 16:07:04 overall, they are pretty nice. Jul 05 16:07:35 do you know of any similar ones that are not touch screens? Jul 05 16:07:37 at 7", the built-in distro is pretty usable, but I use a tiny wireless keyboard/mouse. Jul 05 16:08:03 no. I know of a 10" capacitive touch that I like Jul 05 16:08:22 they might make a version without touch, but I doubt that'd save a lot on the cost. Jul 05 16:08:32 wait resistive is pressure based right? Jul 05 16:08:47 agreed that the touch isn't all that helpful with Gnome on tiny screens. Jul 05 16:08:51 yes. Jul 05 16:08:55 capacitive is what iphones have Jul 05 16:09:00 right Jul 05 16:09:01 static elec based? Jul 05 16:09:02 k Jul 05 16:09:08 so, you can use a stylus with the resisitive. Jul 05 16:09:29 how much is the 10"? Jul 05 16:09:39 I think it was about $150. Jul 05 16:09:43 chalk elec Jul 05 16:09:46 * jkridner googles Jul 05 16:10:41 $135: http://www.chalk-elec.com/?page_id=1280#!/~/product/category=3094859&id=13939433 Jul 05 16:11:12 I haven't tried it on Black, but it should work with a bit of devicetree magic. Jul 05 16:11:29 * jkridner submitted a driver for white. Jul 05 16:11:38 yea im now getting into all of that Jul 05 16:11:48 wrote my first semi serious driver last week Jul 05 16:11:55 lol Jul 05 16:13:30 what im interested in is the LVDS LCD interface board Jul 05 16:13:38 could i use an old laptop screen with it? Jul 05 16:13:41 if its LVDS? Jul 05 16:21:55 http://www.chalk-elec.com/?page_id=1280#!/~/product/category=3094861&id=14647633 Jul 05 16:22:00 really cool Jul 05 16:22:10 this + $6 nano screen Jul 05 16:22:34 nano as in netbook* Jul 05 16:23:36 d'oh.... Jul 05 16:24:04 deller: OK does that work? :O Jul 05 16:24:09 no idea Jul 05 16:24:17 gonna try Jul 05 16:55:04 hi. i could swear i saw somewhere how to setup my beaglebone to access internet via usb-pc instead of ethernet. Jul 05 16:55:15 i cant seem to find it now though Jul 05 16:55:20 hints? Jul 05 16:56:48 I think that is the Ethernet Gadget you are thinking of. Jul 05 16:57:23 And once you have that working, you will also need to bridge that connection with the host's other connection to actually get Internet. Jul 05 16:57:33 or just NAT Jul 05 16:57:49 Right, or internal NAT. Jul 05 17:10:53 looking into internal nat Jul 05 17:10:56 thanks Jul 05 17:29:13 panto: I added the cape to the optargs: capemgr.enable_partno=BB-BONE-AUDI-01 and it doesn't work, yet works if I use the echo > /sys/devices/bone-capemgr... method Jul 05 17:32:52 jmoyerman, you have an older release/kernel Jul 05 17:33:29 panto: I should note i'm using debian: Linux bbb-one 3.8.13-bone20 #1 SMP Wed May 29 03:11:01 UTC 2013 armv7l GNU/Linux Jul 05 17:37:38 ^May 29 is too old Jul 05 17:38:18 Ok. I'll update the kernel. I'd rather do that and it work, then it not work the proper way Jul 05 17:38:21 * mru spotted a car with licence plate 1-ATT-666 Jul 05 17:38:23 Thank you for the help. Jul 05 17:39:01 mru, thats awesome Jul 05 17:39:14 * ka6sox remembers the bloom county with the "Death Star" Jul 05 17:42:41 <_Sy_> Hello Jul 05 17:46:58 panto: do you think v3.8.13-bone21 will be up to date enough? Or will I have to pull down the latest and greatest and compile it myself? Jul 05 17:54:38 <_Sy_> quiet here tonight Jul 05 17:55:12 _Sy_, a lot of us are on holiday from burning meat and blowing up things. Jul 05 17:55:14 mru, you around ? Jul 05 17:55:26 jmoyerman, the latest official release works Jul 05 17:55:38 anyone here toying with ds5 ? Jul 05 17:55:42 <_Sy_> :) warm here for a change, probably means rain tomorrow Jul 05 17:56:31 panto: i'll do some more poking around, probably just compile it myself to be safe. Jul 05 17:56:47 morning everyone Jul 05 17:56:51 heh Jul 05 17:57:02 * m_billybob has been up for 6 hours already Jul 05 17:57:13 it's already 14:00 here Jul 05 17:57:20 nearly 11 am here Jul 05 17:57:42 nearly beer o'clock here Jul 05 17:57:43 actually ive been up for almost 8 hours Jul 05 17:57:50 3 mins for liftoff Jul 05 17:58:00 passed out at like hell idk 7-8 last night Jul 05 17:58:18 SO no one here has even heard of ds5 ? Jul 05 17:59:01 I think we all know ds2 Jul 05 17:59:04 is ds5 similar? Jul 05 17:59:38 many geeks here also know ds9 Jul 05 17:59:48 ds5 is some tool made by arm not sure exactly what it is. my buddy seems all hot and bothered by it, but yeah . . .hes not exactly a software developer Jul 05 18:00:00 yeah ive been watching ds9 for the last 2 weeks lol Jul 05 18:00:30 he was reading EDN and i guess they mentioned it Jul 05 18:01:05 <_Sy_> not a fan of ds9, never goes anywhere...prefer 7of9 :) Jul 05 18:01:15 ah, ok its just a tool chain. No thanks . . . Jul 05 18:01:38 http://www.arm.com/products/tools/software-tools/ds-5/index.php Jul 05 18:02:55 very much like CCS by TI Jul 05 18:03:07 or so it seems Jul 05 18:03:18 Everybody is using eclipse now Jul 05 18:03:30 i refuse to use eclipse. Jul 05 18:03:30 i am not Jul 05 18:03:38 whats eclipse? Jul 05 18:03:44 or anythign based on java Jul 05 18:03:46 not "everybody" but a lot Jul 05 18:03:50 <_Sy_> so many variants of eclipse about Jul 05 18:03:52 java based IDE ka6sox Jul 05 18:04:05 <_Sy_> whats wrong with java? Jul 05 18:04:18 whats wrong with visual studio Jul 05 18:04:53 ok, I'm outta here Jul 05 18:05:00 have a kickass weekend everybody Jul 05 18:05:06 <_Sy_> Although VS is from MS, it isn't a bad IDE. Jul 05 18:05:09 long story short, i dotn want JVM crapping up my windows machines. thats all Jul 05 18:05:12 <_Sy_> u2 panto Jul 05 18:05:31 <_Sy_> Java is a lovely language compared to C++ Jul 05 18:05:46 Java is much more verbose than C++, and slower imo Jul 05 18:05:56 now ask a real programmer their thoughts about java ;) Jul 05 18:06:17 nite Panto Jul 05 18:06:24 cu monday! Jul 05 18:06:28 <_Sy_> it is slower because it isn't compiled...but it is better in terms of its OO approach...C++ lets you do just about anything and break the OO model Jul 05 18:06:29 night panto Jul 05 18:06:40 speed is going to be similar Jul 05 18:06:50 interprited languages versus native Jul 05 18:06:56 Embedded + Java....Just Say NO! Jul 05 18:07:03 interprited will definately use more CPU though Jul 05 18:07:17 <_Sy_> Java and Native are possible, do it all the time. Jul 05 18:07:35 lots of people use JNI Jul 05 18:07:38 java runs on C++ :P lol. Jul 05 18:07:40 <_Sy_> yep Jul 05 18:07:57 I just dont like java as a language Jul 05 18:08:05 dont like php or perl either Jul 05 18:08:21 running Java on a 'Bone ranks right up there with compiling on one....Just Say NO! Jul 05 18:08:30 yep. Jul 05 18:08:46 <_Sy_> these days they are all very similar, only main difference between java and others is you can't do pointers, althought there are a lot of similarities between references and poiinters. Jul 05 18:08:49 ka6sox running java on the bone though might be better than running javascript . . . but im a native type of person myself Jul 05 18:08:56 I wouldnt run python on the BBB either Jul 05 18:09:16 I honestly dont see the point Jul 05 18:09:38 more CPU usage == more power usage Jul 05 18:09:52 <_Sy_> With a lot of projects there are a ton of portable classes already written that you can use Jul 05 18:10:20 there are many many more libraries for C than most seem to think Jul 05 18:10:21 <_Sy_> The socket interface works very well in Java on BBB. Jul 05 18:10:37 and if that wont cut it there is always C++ Jul 05 18:10:43 boost . . .etc Jul 05 18:10:45 <_Sy_> but with C they aren't as portable and in most cases specific to hardware Jul 05 18:11:11 why does portable matter Jul 05 18:11:34 if you need the native to run on a slightly different software platform you just recompile for that platform Jul 05 18:11:40 <_Sy_> Because you can take code written for x86 and run it on Arm without modification, that can't be said for almost all C code. Jul 05 18:12:12 but its not written for x86 Jul 05 18:12:19 its written for the JVM Jul 05 18:12:23 python makes perfectly sense if you want to do prototyping stuff or if performance has no high priority Jul 05 18:12:27 the JVM abstracts that away Jul 05 18:12:54 Most C code is widely portable, if you don't make assumptions about things like integer sizes and endian-ness Jul 05 18:13:05 yeap Jul 05 18:13:15 and if those things matter to your code, using something like python wouldn't have been a serious option anyway. Jul 05 18:13:16 <_Sy_> Thats the point, Java is really portable, C was supposed to be portable but never really is. Jul 05 18:13:18 just means you need to know more about your hardware is all whcih is a good thing Jul 05 18:13:37 (or java) Jul 05 18:13:48 <_Sy_> If you do anything with C in terms of hardware, most of the time it isn't platform independant. Jul 05 18:14:17 its going ot be the same for any language Jul 05 18:14:26 only difference is runtime Jul 05 18:14:34 Strangely, code that deals directly with hardware often isn't platform independent. :) Jul 05 18:14:56 strangly ? Jul 05 18:15:02 I was being ironic. Jul 05 18:15:03 ;) Jul 05 18:15:08 <_Sy_> With the project I have now on PC104, x86 running in QNX, if we changed the hardware it would take me less than a week to port the code to the new platform, thats because only the hardware driver which provides JNI routines is coded in C, the rest of the project is written in Java. Jul 05 18:15:20 It seems like a tautology, code to write to hardware isn't hardware independent. Jul 05 18:15:47 _Sy_ accessing sysfs from java, python, C/C++ etc is all "basically" goign ot be the same Jul 05 18:16:02 that code is goign ot be portable Jul 05 18:16:07 from one distro to the next Jul 05 18:16:32 <_Sy_> Yes, true there are guide lines for writing portable C like the POSIX standards...but its easier in Java. Jul 05 18:17:11 I guess that depends on your skill level with the languages in question Jul 05 18:17:29 have to let the language fit the project in my opinion. Jul 05 18:17:51 different aspects though jmoyerman Jul 05 18:17:56 you could argue either way Jul 05 18:18:05 <_Sy_> I consider myself pretty good with C / C++ and Java...I've written the device driver in C for the PC104 TomCat...but I prefer using Java because the code is more elegant and the model is nicer. Jul 05 18:18:13 you could for example argue ease versus CPU usage Jul 05 18:18:17 It's easier in java as long as you distribute packages for all your intended platforms that includes the right JVM for each of them. Jul 05 18:19:10 You don't see many apps distributed as just jars, "run this on whatever JVM you happen to have", because java changes so much. Jul 05 18:19:10 <_Sy_> Better crack on...have a nice weekend Jul 05 18:19:52 I dont have a very high opinion of java. syntactically I think its a butt ugly language Jul 05 18:20:30 C# ( one of my favorite interpreted langauges can be just as bad though Jul 05 18:20:47 I think Java had some good ideas (interfaces were an improvement on C++) but problems with JVMs made it awful. Jul 05 18:21:30 Its a regular security hazard on Windows ( JVM that is ) and for the systems I use, it can sometimes be dog slow Jul 05 18:22:55 I've been told it can be slow like that because of a few different reasons . . . but yeah I dont really care any more. JVM is oneof those things Iavoid now days, and my windows systems are a lot happier Jul 05 18:23:12 I just try to avoid java and windows entirely :P Jul 05 18:23:38 Slowness is definitely one of its big problems. And size (memory footprint, and even download size). Jul 05 18:23:44 Windows is my prefered desktop Jul 05 18:24:12 I prefer linux Jul 05 18:24:21 I use both :) Jul 05 18:24:39 Linux here. Jul 05 18:25:21 I've been using MS OSes since dos 5, and Linux since IDK mid 90's Jul 05 18:26:39 average user + Windows also has made me a good bit of money in the past lol Jul 05 18:38:47 one thing I hate about the beagle... removing capes... Jul 05 18:39:58 <_av500_> I use a shovel Jul 05 18:40:18 lol. Jul 05 18:43:38 lol Jul 05 18:43:59 better than using a hamer I suppose Jul 05 18:44:32 hacksaw. that was a good idea. Jul 05 18:44:45 blowtorch, maybe Jul 05 18:45:23 C4 <--- since it close to the 4th of july Jul 05 18:45:41 dual purpose, loud bang, and removal Jul 05 18:46:22 det cord would work too but not nearly as entertaining. Jul 05 18:48:03 m_billybob, too fast Jul 05 18:48:13 :) Jul 05 18:48:18 I'd prefer for it to be intact afterwards..... lol. Jul 05 18:48:33 awe come on what fun is there in that ? Jul 05 18:48:56 didnt you blow army men up as a kid with firecrackers ? Jul 05 18:49:08 Hi all ! I have too much "Oops" with my BBXm C4....any one would like to help me to debug ? Jul 05 18:49:56 dont ask to ask krisfr92, but a pastebin of the message may help Jul 05 18:50:06 oki Jul 05 18:50:47 cant garuntee ill know the answer but i'll try Jul 05 18:51:07 * ka6sox gets popcorn Jul 05 18:51:14 * jmoyerman steals some Jul 05 18:51:25 what no beer ? Jul 05 18:51:42 m_billybob, I doubt my routing would be better with Beer. Jul 05 18:51:54 routing ? Jul 05 18:52:03 ah gotcha ( i think ) Jul 05 18:52:13 not quite finished yet ? Jul 05 18:52:34 ka6sox: ever have the beaglebone lock you out of ssh after configuring the fpga? haha Jul 05 18:53:30 jmoyerman, no Jul 05 18:53:50 m_billybob, nope Jul 05 18:53:55 still tweaking Jul 05 18:54:04 i need to read about your project again Jul 05 18:54:16 anybody here use AVRdude? Jul 05 18:54:18 to see how useful it would be for me again Jul 05 18:54:34 I'll admit it's a weird issue Jul 05 18:54:36 ka6sox swiss army knife debugger right ? Jul 05 18:55:13 or am I thinking of Russ's project again ? lol Jul 05 18:55:14 m_billybob, something related to programming of Atmel parts. Jul 05 18:55:25 m_billybob, I think you are Jul 05 18:55:34 ka6sox, i meant your BB cae / project Jul 05 18:55:40 cape* Jul 05 18:56:20 ka6sox lol ok fair enough. learning so much over the last several month im surprised i can remember my own name sometimes. Sorry.

Jul 05 19:13:39 good question...cannot test because my greenhouse is running ! Jul 05 19:16:11 krisfr92, ok im stumped. You may consider askign Robert on his debian setup pages ( in the comments section ) or perhaps on the Beagleboard google groups Jul 05 19:16:43 be sure to include Kernel version, say its debian, etc etc, and give the oops message Jul 05 19:16:44 hello Jul 05 19:17:14 hello Jul 05 19:17:27 ok, thanks m_billybob Jul 05 19:24:14 krisfr92 no problem sorry I couldnt be more helpful Jul 05 19:24:39 ill bbl time to go play with our 100GAL / minute irrigation system Jul 05 20:07:18 15:54:29 --> | akk (~akkana@adsl-69-105-235-1.dsl.pltn13.pacbell.net) has joined #beagle │ dk-_ Jul 05 20:07:22 oops.. sorry Jul 05 20:08:00 <_Sy_> Hello again Jul 05 20:08:49 <_Sy_> I'm not sure if I've found a problem or not....I've added two serial devices and these work, I can send and receive on both devices from a shell.

Jul 05 22:10:31 kfoltman, you only bring us the finest in OOPSes Jul 05 22:10:55 ka6sox: figured out why my BCC cape was borking the board... turns out I was mucking the eMMC pins Jul 05 22:14:58 m_billybob: you rang... Jul 05 22:32:12 jmoyerman, whoops Jul 05 22:33:09 Yeah. It turns out the example files on eric's site were doing that... his blinky example is fixed now, gotta talk to him a bit more about it though. Jul 05 22:34:04 porcodio Jul 05 22:35:37 c'è nessuno?? Jul 05 22:36:09 pig is a god Jul 05 22:36:21 minchiadiled: what?

Jul 05 22:37:54 I haven't worked with the digital IO on the beaglebone, but maybe if you were to say which sensor, and what board you were using somebody would be able to help you Jul 05 22:38:21 pir sensor Jul 05 22:40:05 What is the output? Jul 05 22:40:50 0v or 3.3v Jul 05 22:57:37 emeb: thanks! Jul 05 22:57:51 mrpackethead: sure Jul 05 22:58:08 we'll get all the bugs out of it yet! Jul 05 22:58:25 emeb: have you run it up with a BBB? Jul 05 22:59:09 mrpackethead: yes. Jul 05 22:59:22 did you have the same problem? Jul 05 22:59:23 that's how I knew to fix the GPMC stuff. Jul 05 22:59:32 ahh Jul 05 22:59:40 emeb: did you see my latest email? Jul 05 22:59:47 actually made that change about a month ago, just didn't propagate it to the web page. Jul 05 23:00:03 jmoyerman: yeah. No idea what's up with that. bcc_test.bit works for me. Jul 05 23:00:19 d'oh... Jul 05 23:00:46 I think I might just need to wipe a lot of files off of my pc and start fresh with the bcc_tst Jul 05 23:02:17 <[yAK]> anyone have any recomendation of a temp sensor that i can put into my bbq and hook into the beaglebone black from a breadboard? i saw a tutorial on adafruit (i believe?) that is using a temp sensor but its just a tiny thing and apparently isnt safe to use on anything that goes above 200Cish Jul 05 23:03:10 <[yAK]> (i want to make a wireless temp monitor for the bbq using the beaglebone black if you didnt guess) Jul 05 23:03:15 mrpackethead: You hired an idiot for a software developer.. Jul 05 23:03:40 BBQ, BeagleBone Quack? Jul 05 23:03:54 jmoyerman: that suggest's i'm an idiot too. Jul 05 23:04:07 You've already told me that... So I'm just repeating Jul 05 23:06:57 nope... same issue... odd Jul 05 23:33:57 BBB BBQ? Jul 05 23:40:54 MAX31855 Jul 05 23:41:02 Ktype thermocouple Jul 05 23:44:38 <[yAK]> nice!... how exactly does something like that hook into the beagleboard? is there anything else that would be needed? the one temp sensor i found warned that if it were to go above a certain temp it would send more voltage to the board than it could handle? Jul 05 23:46:12 its SPI Jul 05 23:46:24 get the datasheet from adafruit and start reading. Jul 05 23:49:46 YAK, i will tell you that the BBB is waaaay over kill for such an application. Jul 05 23:49:58 and msp430 could do that easily Jul 05 23:50:02 an* Jul 05 23:50:25 infact, and msp430 has been used to exactly that purpose Jul 05 23:50:31 used for* Jul 05 23:51:13 <[yAK]> yea? making a webpage that you can monitor various temps? see the problem is i bought a beaglebone black and now am wanting to do things with it :p Jul 05 23:52:07 I've seen some people do similar tasks with web interfaces Jul 05 23:52:18 nothign wrong with wanting to use the BBB though Jul 05 23:52:30 just saying its very overkill lol Jul 05 23:52:42 <[yAK]> i figured i might as well try to learn with it while doing things i actually already do ;) Jul 05 23:53:21 <[yAK]> grilling.. beer making.... possibly broadcast/control my wifi underwater webcam im making for my pond Jul 05 23:53:51 what kind of broadcast control Jul 05 23:54:14 <[yAK]> ummmm just general streaming h264 if possible Jul 05 23:54:28 ah so not rteally broadcast then. Jul 05 23:54:42 you say broadcast i think TV/Radio Jul 05 23:54:45 <[yAK]> no just take the signal and send it out ;) Jul 05 23:54:51 sicne iknow peopel who work in both fields Jul 05 23:55:05 <[yAK]> just pretty simple stuff i think Jul 05 23:55:07 my buddy here is a radio station engineer Jul 05 23:56:40 so yeah interfacing the max31855 would probably be a cool project to keep yourself busy Jul 06 00:23:53 [kernel] ZubairLK opened pull request #47: 3.11 (3.11...3.11) http://git.io/pvTRGQ Jul 06 00:28:28 [kernel] ZubairLK opened pull request #48: 3.8 (3.8...3.8) http://git.io/1RQQkQ Jul 06 00:28:41 really.
