**** BEGIN LOGGING AT Mon May 14 02:59:59 2012 May 14 03:05:36 So hopefully I'll get the bone tomorrow. May 14 03:05:37 :) May 14 03:05:45 I can start porting the pybbio to C++ May 14 03:08:19 heh, one horrid language to another :-D May 14 03:09:41 what kernel module do I need to load for analog inputs to propigate in /sys? May 14 03:10:26 beagle or bone? May 14 03:17:52 bone May 14 04:18:49 hi May 14 04:22:05 hi May 14 04:28:04 do you know of a free program to design pcb boards? May 14 04:56:48 left before i could answer May 14 05:03:25 mranostay: they always do May 14 05:03:43 mranostay: younger generation has no staying power May 14 05:04:38 * mranostay hides his age :) May 14 05:06:47 * mranostay rocks out with Eagle ATM May 14 05:58:42 XorA: don't run 1000 patches through your spamfilter, it will make any FLOSS mail as spam afterward :) May 14 05:59:05 * koen wondered why last week was so quiet May 14 06:00:51 koen: hehe, probably for the best :-D May 14 06:02:15 XorA: so if you sent me any mail last week, resend :) May 14 06:02:37 koen: nope May 14 06:03:51 * XorA is still suffering overheat error in Korea May 14 06:05:54 https://cosm.com/users/koenkooi May 14 06:06:07 * koen hooked up a beaglebone to the cloud May 14 06:07:09 koen: awesome-o May 14 06:28:40 koen: hell froze over at 5:06?-) May 14 06:30:10 yes May 14 06:30:32 the ds18b20 gives a 0 degrees C reading every few hours May 14 06:31:24 better than -273 I guess May 14 06:37:11 oebb wrapper broken ? May 14 06:50:22 hi there! May 14 06:50:45 hi May 14 06:50:55 Has somebody already spotted the error described here: http://comments.gmane.org/gmane.linux.embedded.yocto.meta-ti/340 May 14 06:51:43 not me, i am not even bale to set up a proper build environment May 14 06:51:46 *able May 14 06:52:23 hm, thos 4 steps are really tough :p May 14 06:52:28 s/those/those/ May 14 06:52:31 ok, I just wondered if the described fix is good fix or just a dirty hack ;) May 14 06:52:45 it smells May 14 06:53:20 bitbake should bomb out on some unset random variable May 14 06:53:31 s/should/shouldn't/ May 14 06:53:40 * ynezz needs more coffee May 14 06:56:15 hrmmm May 14 06:56:30 using the steps here to set up environment: http://www.angstrom-distribution.org/building-angstrom May 14 06:58:33 but you didn't told us the error yet... May 14 06:58:37 https://pad.puscii.nl/p/angstrom May 14 06:58:38 there May 14 06:58:40 sorry May 14 06:59:44 1) use pastebin 2) can't see error May 14 06:59:56 seems fine for me too May 14 07:00:57 My guess: install makeinfo May 14 07:01:04 tasslehoff: done that May 14 07:01:39 fierman: ubuntu? May 14 07:02:11 tasslehoff: yeah :( May 14 07:02:29 makeinfo should be in texi2html, which is up to date May 14 07:04:46 fierman: hm. installing that package removed the error for me when I had it May 14 07:05:43 tasslehoff: i will blame apt then. will check again, thnx May 14 07:06:14 or if you're brave enough, remove that check May 14 07:06:52 the sanity check, yes May 14 07:07:00 not THAT brave :) May 14 07:40:59 btw. for beagleboard specific questions on angstrom, is this the channel for discussion, or would #angstrom be a more appropriate place? May 14 09:11:26 Hi everyone! I'm looking for a circuit that can protect the beagleboard from short on the exapnsion board. Any ide? May 14 09:11:29 idea May 14 09:12:31 buffers? May 14 09:12:52 expoxy May 14 09:12:54 -x May 14 09:14:14 I mean, error of connection, problem with I/O May 14 09:14:25 that could broke the CPU May 14 09:14:57 what for? May 14 09:17:34 don't overvolt it, thats all. May 14 09:18:12 use galvanic isolated level shifters on every i/o line :) May 14 09:22:47 optocoplers May 14 09:23:36 octocopters May 14 09:24:58 opto--coppers? May 14 09:25:41 hey, marketing division - should we ship the gaxboard with integrated optocoppers? May 14 09:26:33 octocopters with integrated gaxboards might be more successfull May 14 09:26:39 hm. May 14 09:38:42 optocopler seems to be a good alternative May 14 09:40:41 not to forget diodes on the power connector May 14 09:41:09 power on the diode connector? May 14 09:42:55 connect power on the diode May 14 09:43:29 power diode the connector? May 14 09:43:32 use a GZ34... May 14 09:47:27 Hi May 14 09:47:43 I want to learn to use the dsp processor on my beagleboard May 14 09:47:53 I'm interested in image processing May 14 09:48:05 what would be a good starting point? May 14 09:49:26 hii May 14 09:50:07 i am looking for the exact u-boot sources for beagleboard xm - c for debugging purposes. I searched a lot but could not locate anything May 14 09:50:48 bo_: depends May 14 09:51:58 would compressing images require the DSP? May 14 09:52:07 would that be a simple first project? May 14 09:52:10 I need ideas May 14 09:52:56 you could run through the examples first May 14 09:53:13 if you run agnstrom, you should have dsplink and examples already there May 14 09:53:13 make an automatic x-rating detector. :) May 14 09:53:25 what's that? May 14 09:53:29 ohh May 14 09:53:38 i smell huge profit opportunities there, selling to apple :) May 14 09:53:48 LetoThe2nd: yes, the UK government is in dire need of such a thing May 14 09:53:50 that would be fun May 14 09:54:19 but what would be the basic dsp programes for starters ... relating to image processing May 14 09:54:41 av500: hehe. think $MUSLIMFASCISTGOVERNMENT... May 14 09:55:36 hi there i need some help bringing the angstrom demo up to the board May 14 09:56:07 a card-butler? May 14 09:56:14 iam done with making the card and it boots but after "Unkompressing Linux.........done,booting the kernel." nothing happens anymoe May 14 09:56:37 Iam connected via serial connection May 14 09:57:04 bo_: I'd suggest you a have a look at the dsplink and CE (Codec Engine) examples May 14 09:57:15 and manahge to run them May 14 09:57:18 -h May 14 09:59:14 then you can take e.g the viddec_copy example and insert your own code May 14 09:59:45 bo_: OR, you look at http://processors.wiki.ti.com/index.php/C6EZRun May 14 10:00:11 that allows you to run code easily on the DSP side, it least that is what it promises May 14 10:00:30 is it nessesary to connect 5V power supply to boot the angstrom kernel? May 14 10:00:45 any kernel likes 5V May 14 10:01:00 yet its connected via USB May 14 10:02:07 it should be enough current to boot up angstrom, doesn't it? May 14 10:03:54 m0erk: if in doubt, try May 14 10:04:17 he did May 14 10:06:31 not yet, searching for a power supply :P May 14 10:07:04 its not normal though.. always stops after "..done, booting the kernel." May 14 10:07:23 i did everything described in angstrom beagleboard demo how to May 14 10:07:43 which beagle? May 14 10:07:52 -xm rev c May 14 10:07:58 doesn't work with usb May 14 10:08:05 shure? May 14 10:08:10 ubuntu does May 14 10:08:28 only angstrom is makeing trouble May 14 10:08:42 yes, its a little troublemaker May 14 10:08:48 :D May 14 10:09:00 i see May 14 10:36:09 i connected 5v power supply but the same error May 14 10:36:27 just stops after "...done, booting the kernel." May 14 10:36:43 does the led blink? whats your uEnv.txt? May 14 10:37:31 *** Unable to read uEnv.txt from mmc *** May 14 10:37:54 which u-boot-version? May 14 10:38:01 one led is blinking the other is not (talking about the two at the sd card) May 14 10:38:23 http://downloads.angstrom-distribution.org/demo/beagleboard/u-boot-beagleboard-2011.12-r4.img May 14 10:38:30 if it blinks, the kernel does run. May 14 10:38:49 maybe your console is wrong. May 14 10:39:01 or you are useing quiet May 14 10:39:07 or something like that May 14 10:39:21 its just the demo image from angstrom May 14 10:39:38 console is wrong? do you mean the setup with baudrate? May 14 10:39:54 no, console=foobar May 14 10:40:13 which kernel? May 14 10:40:18 where do i have to set this up? May 14 10:40:39 2.6.32 May 14 10:40:41 http://downloads.angstrom-distribution.org/demo/beagleboard/Angstrom-Beagleboard-demo-image-glibc-ipk-2011.1-beagleboard.rootfs.tar.bz2 May 14 10:41:20 2.6.32 doesn't work with newer u-boot's. 2.6.32 uses ttyS2, u-boot ttyO2 May 14 10:41:32 so you need an uEnv.txt May 14 10:42:05 do a printenv at the u-boot-command-line May 14 10:42:43 i did May 14 10:43:35 console = tty02,115200n8 May 14 10:43:46 that will never work May 14 10:43:55 O != 0 May 14 10:44:28 k May 14 10:44:38 yes might be O May 14 10:44:45 ttyO2 also wrong? May 14 10:44:53 for .32 yes May 14 10:45:03 so it should be 1? May 14 10:45:17 look above May 14 10:46:18 can i set this anyhow? May 14 10:46:31 setenv work for one boot? May 14 10:46:50 yes, uEnv.txt is for persistence May 14 10:47:02 or NAND which the -xm doesn't have May 14 10:47:48 ok thanks !!! May 14 10:48:00 actually it shows up a bootsequence May 14 10:48:27 create uEnv.txt with a line "console=ttyS2,115200n8" May 14 10:48:52 yes, thanks alot! May 14 10:48:54 and ask mru about line endings ;) May 14 10:49:28 it needs unix-style line endings May 14 10:50:04 what does that mean again? :P May 14 10:51:28 http://lists.denx.de/pipermail/u-boot/2012-May/124335.html May 14 10:51:42 m0erk: what editor are you using? May 14 10:51:50 (i should be able to read from console always, right? even if no bootable card is inserted) May 14 10:51:56 nano May 14 10:54:19 aholler, I'm hoping that at least that one problem goes away in my lifetimeā€¦not looking good so far. May 14 10:55:51 i think that problem (crlf vs lf) will last for several generations more May 14 10:56:16 but even sun died, why not m$ ;) May 14 10:56:28 a terrible legacy to leave for the next generation :( May 14 10:59:59 rofl ok May 14 11:00:05 aholler, nice patch, btw May 14 11:00:12 iam quite new to the linux stuff May 14 11:00:35 i need twice the time to get all this :P May 14 11:02:45 mdp: I stumbled over that problem a year ago when I created an uEnv.txt in windows myself and offered and mailed the first version of that patch to jkridner and koen with the comment "mainline wouldn't accept it" ;) May 14 11:04:14 sometimes I'm astonishing myself. May 14 11:04:21 well, it always depends on how deeply care about the feature :) May 14 11:04:43 even uart SPL support was first met with "no, never, I won't allow this pandora's box to be opened!!!" May 14 11:04:46 :) May 14 11:06:14 CEMK Error: Failed to request_mem_region(0x8000000 -> 0xa000000= May 14 11:06:51 forget that please :) May 14 11:07:13 still got probs at starting up May 14 11:07:27 but i need some food before.. back in an hour or so May 14 11:07:45 if you use an old kernel, use the u-boot for that kernel too May 14 11:08:09 because it contains some kernel-cmdline-parameters you now might missing May 14 11:08:39 ok but i used the recommended uboot file from the angstrom demo site May 14 11:08:51 i will try something else after... May 14 11:09:12 there are multiple versions of u-boot and the kernel and .32 is very old May 14 11:09:28 but the only one which might boot with power over usb May 14 11:10:06 and it seems to support 1GHz ;) May 14 11:18:17 but I have to admit, that kernel cmd-line handles CR like spaces ;) May 14 11:18:29 just had a look at it May 14 11:18:52 at least if isspace in kernel is the same like posix-isspace May 14 11:19:17 which the comments are stating May 14 11:20:17 but CRs still makes the dmesg-output with the cmdline unreadable May 14 11:21:38 and some stuff in the boot-script might fail. at least I get some obscure failures with my modifed env and unignored CRs May 14 11:23:39 xml all the things May 14 11:41:44 hi May 14 11:42:05 i have a beagle bone with angstrom and i have a problem, maybe someone can halt May 14 11:42:09 help May 14 11:42:22 maybe May 14 11:42:30 i have a usbtoserial ftdi stick May 14 11:42:42 how would i make a ttyusb device out of this? May 14 11:43:02 lsusb shows the stick May 14 11:43:47 stick plugged into bone usb? May 14 11:44:13 probably you need to install kernel-mod-serial-usb-ftdi or whatever koen called it ;) May 14 11:45:18 i installed kernal-modul-ftdi-sio May 14 11:45:45 i installed kernal-modul-usbserial May 14 11:46:27 if i do a modprobe ftdi_sio i get a FATAL: Module ftdi_sio not found. May 14 11:46:54 * LetoThe2nd suspects version mismatch. May 14 11:47:00 dmesg May 14 11:47:01 i am missing a step, i guess.

May 14 11:55:12 I followed instructions given in http://code.google.com/p/opencv-dsp-acceleration/wiki/Instruction_For_Building_Examples May 14 11:55:38 I copied libopencvdsp.so to /usr/lib May 14 11:55:51 NAP: paste a full log of dmesg at dpaste.com May 14 11:58:41 jkridner__: ping May 14 11:58:48 ponh May 14 11:58:51 er, pong even May 14 11:59:05 when I try to compile the code it gives me this error May 14 11:59:07 http://pastebin.com/zZG48adA May 14 11:59:46 aholler: http://dpaste.com/747958/ May 14 12:00:47 jkridner__: can you have a look at http://dominion.thruhere.net/koen/angstrom/beaglebone/capes/ ? May 14 12:01:14 jkridner__: it's a quick c&p hack to read a minimal cape json and populate the mux from debugfs May 14 12:01:46 NAP: looks like the driver is missing May 14 12:02:07 aholler: how would i install the missing thing? May 14 12:02:18 jkridner__: you'll need https://raw.github.com/beagleboard/kernel/9d91d5ee287ec753b9ec7f6a72e9da226d222fad/patches/beaglebone/0041-ARM-OMAP-Mux-Fixed-debugfs-mux-output-always-reporti.patch as well, though May 14 12:02:26 NAP: sorry, can't help with that May 14 12:03:59 anyone? its just installing a ftdi device. that cant be that complicated? May 14 12:07:04 DO I have to copy libopencvdsp.so into any other folder? May 14 12:11:11 koen: why are you reproducing mux.js from much of eeprom.js? May 14 12:11:35 NAP: it worked for me. does lsmod show pl2303.ko? May 14 12:13:08 pl != ftdi May 14 12:13:25 koen: don't we have most of the eeprom functionality already? which part of it is new? May 14 12:14:20 lsmod shows no modul at all May 14 12:14:40 koen: where is the part that is setting the muxes based on the eeprom values? May 14 12:15:25 koen: could you just use the new getEeproms and pinMode functions? May 14 12:15:41 pinMode now handles slew, pullup, etc. May 14 12:19:54 jkridner__: Like I said, it's a quick c&p hack May 14 12:20:06 jkridner__: the meat is at the botton, in the loop May 14 12:20:08 I just thought it was already done. May 14 12:20:19 jkridner__: 328-351 May 14 12:20:34 it reads the function from debugfs May 14 12:20:40 prohitkpr: looks like you are missing some c6run lib to link against May 14 12:20:47 also you paste is truncated May 14 12:20:49 but not the current settings (mode, direction, slew, etc) May 14 12:20:50 your May 14 12:21:31 av500: Thanks!

Thanks! May 14 12:29:36 you dont need to include the header May 14 12:29:41 you need to link against the lib May 14 12:31:12 I have ogre 1.8rc1 running in oe-classic using gles, but struggle with gles2. It wants to use FrameBuffer Objects and segfaults somewhere in the SGX-driver (http://pastebin.com/3AGyugu3). Anyone know if FrameBuffer Objects should/could work in libgles-omap3:4_03_00_02, omap3-sgx-modules:1.6.16.3977? May 14 12:43:17 where can I get these librarues. Do I have to build them? May 14 12:51:11 is there any NAND flash for storing bootloader on the beaglebone? May 14 12:51:25 yes, on the sd card May 14 12:51:46 koen: thx May 14 12:53:13 Is it the same functionning between beaglebone and beagleboard xM, except hardware? May 14 12:53:29 I mean, concerning GPIO configuring, etc.. May 14 12:54:02 more or less May 14 13:03:37 koen: any idea which forum/ML I can turn to with my powervr-drivers/libgles woes? May 14 13:04:03 tasslehoff: no use in reporting if you aren't use the latest :( May 14 13:05:04 jkridner__: ncbas' eeprom parser shows that a lot of eeproms are broken May 14 13:08:36 koen: I've pushed two simple workarounds to my tree at github! May 14 13:09:39 ncbas: I noticed! May 14 13:10:49 where do I find that parser? May 14 13:10:58 jkridner__: https://github.com/modmaker/linux/commits/cape_configuration_from_eeprom May 14 13:11:20 ah May 14 13:13:48 koen: dump coming soon, had to revert hw back to own cape first. May 14 13:15:14 ncbas: I merged in the smaller patches: https://github.com/beagleboard/kernel/tree/beaglebone-3.2/patches/beaglebone May 14 13:15:32 ncbas: 38, 39 and 41 May 14 13:20:27 av500: Thanks! May 14 13:20:41 koen: ok. May 14 13:25:17 koen: thanks for 40, that makes some people happy :) May 14 13:34:07 how can i use those "u-boot-scripts"? May 14 13:34:11 .SCR FILES May 14 13:34:35 looks like an uEnv.txt file or so May 14 13:34:52 not really May 14 13:35:26 https://www.google.com/search?q=boot.scr+uboot May 14 13:35:42 no lmgtfy today? May 14 13:35:46 thx May 14 13:37:24 mru: too much effort May 14 13:55:07 whats the default angstrom root pw? May 14 13:55:21 dottie May 14 13:55:27 or alpine? May 14 13:55:40 ill try thx May 14 13:56:54 av500: dottie matrix? and where's princess vespa` May 14 13:56:55 no May 14 13:57:03 these are iphone root passwords May 14 13:57:59 * mru wants a .matrix tld May 14 13:59:03 ask TI for a matrix .gui May 14 13:59:41 i am wondering. is an uEnv.txt necessary to get uboot going ? May 14 13:59:51 nope May 14 13:59:57 ok May 14 14:00:11 it might be necessary to make it do what you want May 14 14:00:41 since the testing/unstable images i got from narcissus are not booting at all here, and I was wondering whether that could be caused by the absence or misconfiguring of an uEnv.txt May 14 14:01:20 mru: no serial console present atm, so no way to check what is going on. (not even a decent display actually :)) May 14 14:01:32 you really should get a serial cable May 14 14:01:42 i know May 14 14:01:54 or teach uboot to use morse code... May 14 14:01:57 will get one tomorrow, my LFCS is closed today May 14 14:02:19 i just ssh into the ting once it's up May 14 14:02:20 large and fancy computer shop? May 14 14:02:29 local friendly computer store May 14 14:02:36 or u just set up the console via uEnv.txt May 14 14:02:39 google says Lutheran Family and Children Services May 14 14:02:57 same thing May 14 14:03:02 m0erk: but its possible to use the serial console even if no OS is loaded, right ? May 14 14:03:09 or possibly Logical Foundations of Computer Science May 14 14:03:50 you can abort the bootsequence and then set environment variables May 14 14:03:57 av500: local friendly is a synonym for small brick&mortar shop with clerks who are friendly and know what they are doing May 14 14:05:06 fierman: such places still exist? May 14 14:05:16 they do :) May 14 14:05:24 where do you live? May 14 14:05:33 netherlands. near nijmegen May 14 14:06:20 small shop where you can run inside, ask for something completely bizarre, and they will sort of guess wtf you are doing May 14 14:06:30 and usually guess right too May 14 14:07:56 if i install the SGX drivers for angstrom it says "No SGX hardware, not starting PVR." Do i have to activate them too in environment? May 14 14:08:38 here in town the only place remotely sane is maplin May 14 14:08:49 they sell mostly junk but carry some good stuff as well May 14 14:09:00 and some of the staff actually know what they're doing May 14 14:09:02 m0erk: two options: 1) your hardware has no SGX, 2) your sgx install is outdated May 14 14:09:07 if you're lucky enough to find one of them May 14 14:10:03 so it has to be option 2 for me May 14 14:10:14 the drivers are outdated? May 14 14:22:07 jkridner__: do you have a picture of boris+bone with no background? May 14 14:22:18 jkridner__: s/picture/logo image/ May 14 14:22:40 I'd have to check the flickr archive... May 14 14:22:43 that's where I'd have it. May 14 14:24:40 jkridner__: I discovered that linux won't show a bootlogo with it's too big for the screen May 14 14:24:53 jkridner__: so I want something penguin sized for the new logo :) May 14 14:25:00 cool. May 14 14:35:16 _roger_: patch for meta-ti sent, includes Robs pwm patch May 14 14:44:48 koen: did you find http://www.flickr.com/photos/jadon/6312263717/ ? May 14 14:46:42 jkridner__: no, I got stuck in email traffic May 14 14:46:50 jkridner__: but that on is perfect, thanks! May 14 15:06:18 hello May 14 15:06:52 anyone know how to re-direct bitbake log to a file instead of /dev/null? May 14 15:10:10 <_av500_> s\/dev/null\filename\ May 14 15:11:30 s:/dev/null:filename: May 14 15:11:58 <_av500_> oderso May 14 15:12:10 which file I should modify to? May 14 15:12:23 so/dev/nullofilenameo May 14 15:13:07 i think when I run bitbake, it said ERROR: Logfile of failure stored in: /dev/null May 14 15:13:15 NOTE: package pyorbit-2.24.0-r1: task populate_sysroot_postamble: Failed May 14 15:13:40 for example. I think I want to capture Log file of bitbake's May 14 15:20:36 * mranostay scrolls up May 14 15:20:54 and regrets it May 14 15:22:51 ? May 14 15:28:08 prpplague: hey purple! May 14 15:28:16 greetings earthling May 14 15:32:58 prpplague: come in peace? May 14 15:33:42 generally yes May 14 15:33:49 <_av500_> in piece May 14 15:37:46 * mranostay points prpplague to his leader kkeller May 14 15:42:41 Hello. I need to develop a level shifter and Interface to connect LCD (TFT or LVDS) on Beaglebone. May 14 15:42:47 Anyone can help me? May 14 15:43:14 <_av500_> TI has nice level shifters May 14 15:43:18 <_av500_> and nice LVDS drivers May 14 15:45:10 arcaico: *cough* or purchase one already made and tested May 14 15:45:43 arcaico: try looking at the SN75LVDS83B May 14 15:46:29 thx _av500_ and prpplague May 14 15:47:18 I'll look May 14 16:24:35 I'll give up, Tom Rini is the one who made me famous for his tty02, not? May 14 16:43:16 aholler, some days the world is against you May 14 16:43:42 and some days the entire universe is May 14 16:45:53 it's always good to know the enemy ;) May 14 16:53:25 prpplague: Tartarus accepted that serial jtag fix for 37x/xM into the custodian tree..so we're good to go there once merged to mainline May 14 16:57:32 mdp: ahh dandy May 14 16:57:50 mdp / Tartarus did you guys give any feedback on my test video ? May 14 16:58:54 prpplague: still catching up, was gone all weekend..have it marked to take a look May 14 16:59:01 mru: what about the multiverse? May 14 16:59:09 mdp: ok thanks May 14 16:59:10 prpplague: it's also something I would like to learn some tips on May 14 16:59:24 mdp: already know we need a better camera May 14 16:59:33 mranostay: if it exists, it's probably hostile May 14 17:00:26 mdp: sadly, getting the videos looking professional enough is probably going to take a number of failures to get enough experience doing it May 14 17:01:54 prpplague: I'll bet..I've had to tinker enough with the lighting on the lab bench just to get a sane still photo suitable to post May 14 17:02:04 can't imagine video lighting plus audio pickup May 14 17:02:44 prpplague: when I need to do it, maybe I should just train a dependent to be my videographer slave May 14 17:02:55 mdp: i am normally the type of person that is ok with failure in a learning process, but for these types of videos you really have to put them out there for feedback, so everyone gets to see your failures :( May 14 17:04:43 <_av500_> mdp: Klieg lights, lots May 14 17:08:10 http://digital-photography-school.com/how-to-make-a-inexpensive-light-tent May 14 17:08:11 :) May 14 17:09:14 hey, I'm considering doing a small robot driven by cellphone on my spare time. It's my understanding servomotors are poorly controlled from userspace (imperfect timings > imperfect positions). I know the beaglebone has a PRUSS but I also know there are alternativess like libxenomai as for real-time controlling. Which approach is to be considered here ? May 14 17:09:43 <_av500_> pruss for the challegne May 14 17:09:51 <_av500_> challenge May 14 17:10:14 I would suggest Lego NXT May 14 17:10:36 i'm terrible with asm, which I think the PRUSS is made of ! May 14 17:10:43 <_av500_> its made of silicon May 14 17:11:01 calling it asm is insultation to asm May 14 17:11:36 it's constructed of NOPs May 14 17:11:42 how does it work exactly, does it run all the time on a completely independant circuit, or can you call a set of self-programmed functions ? May 14 17:13:04 <_av500_> yes May 14 17:13:58 ynezz: ok, thanks, looks easy enough May 14 17:25:56 what are the taxes to expect when importing from the US (digikey) ? May 14 17:26:21 to where May 14 17:26:47 europe (france) May 14 17:27:29 at least VAT May 14 17:28:10 meh, there's on approx. the same price at wattenrot, with taxes included May 14 17:28:52 besides VAT I think electronics below $100 are free of tax May 14 17:29:05 <_av500_> just import VAT May 14 17:29:13 <_av500_> even aboce 100$ May 14 17:32:09 should come quicker from DE, it's a win/win May 14 18:20:09 * jkridner__ is pulling out hair due to node 0.4 vs. 0.6 diffs. May 14 18:24:26 did they switch to a real programming language in 0.6? May 14 18:24:28 * mranostay ducks May 14 18:27:35 * _av500_ covers May 14 18:27:45 I don't think they've heard of lisp May 14 18:29:12 honestly if you told me 4-5 years ago people would be doing server side stuff in JS... May 14 18:29:52 it's like doing realtime stuff in python May 14 18:30:05 people are doing that? May 14 18:30:21 I think some try May 14 18:52:43 hello, Can someone tell me how to make Restart bit instead of stop bit in i2c of beagleboard? May 14 18:54:30 eh ok May 14 18:55:10 <_av500_> it all depedns on the definition of real time May 14 18:57:04 _av500_: isn't it typically 30 milliseconds? May 14 18:57:16 <_av500_> really? May 14 18:57:38 or is it a buzzword now? :) May 14 18:57:48 <_av500_> now? May 14 18:57:53 <_av500_> always May 14 18:58:43 realime was Mo 14. Mai 18:58:24 UTC 2012 May 14 18:59:22 but I think the rt-patches have 32ms as limit or such May 14 18:59:58 <_av500_> 64.0ms should be enough for everybody May 14 19:00:10 heh i see what you did there May 14 19:00:13 <_av500_> there, Paris May 14 19:01:13 another meaningless term people throw around May 14 19:01:42 at least "exact steps" is 100% clear May 14 19:02:35 microsteps? May 14 19:02:56 Can someone tell me how to make Restart bit instead of stop bit in i2c of beagleboard? May 14 19:03:19 don't send a stop May 14 19:08:31 aholler: but how? I mean, I have installed Angstrom and there should be some file to modify before bitbake so that it works May 14 19:13:38 Sorry, I never used the kernel i2c-api, so I don't know. May 14 19:14:10 maybe include/linux/i2c.h brings some light May 14 19:15:39 or have a look at drivers/rtc/rtc-ds1307.c reading the ds1307 is usally done with a restart May 14 19:17:11 * prpplague is soooo over using the ds1307 May 14 19:18:16 prpplague: like your new chip ae? hows things? :) May 14 19:18:46 prpplague: why? ;) May 14 19:19:13 aholler: costs and features May 14 19:19:19 djlewis: it goes May 14 19:20:01 maybe, but almost everyone knows that chip ;) May 14 19:21:19 aholler: yea the ds1307 is pretty expensive http://search.digikey.com/us/en/products/DS1307Z%2B/DS1307Z%2B-ND/956882 May 14 19:21:27 aholler: $3.35 is singles May 14 19:22:16 aholler: the MCP79410 is just $1.26 in singles, and for the core i2c registers is basically identical to the ds1307 - http://search.digikey.com/us/en/products/MCP79410-I%2FSN/MCP79410-I%2FSN-ND/2480419 May 14 19:22:24 yes, they make profit it's popularity May 14 19:22:42 aholler: plus it has built in eeprom and multiple types of alarms May 14 19:23:27 aholler: the mcp79410 can operate from 1.8V up, so no level shifters needed May 14 19:23:48 i will get a pcf8536 next time ;) May 14 19:24:25 hehe May 14 19:25:49 at least it's the cheapiest one available as breakout incl. battery here. May 14 19:26:06 aholler: that is probably true indeed May 14 19:26:08 aholler: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=43fcb81550f7a16be192b19c77a379c9b27b1585 May 14 19:28:45 prpplague: and if it doesn't work, you just poke dwery :) May 14 19:29:28 I still would prefer if SOCs would include a rtc May 14 19:29:38 koen: hehe May 14 19:29:41 or at least all boards made for use by linux May 14 19:30:09 koen: for which item not working? May 14 19:31:03 * dwery runs May 14 19:32:35 prpplague: rtc May 14 19:32:43 prpplague: you do know he's the rtc maintainer, right? May 14 19:33:07 koen: right, i thought you were referring to the mcp79410 code...... May 14 19:37:54 btw., there is a possibility to get rich by selling rtcs to r-pi users. ;) May 14 19:39:03 is that like selling shovels during the gold rush? May 14 19:39:59 a shovel to upgrade bones with an rtc? ;) May 14 19:40:59 more like selling pet rocks to the blind May 14 19:41:05 my next mini-project will be an attiny85 along with an rtc for usage as usb-rtc ;) May 14 19:41:41 prpplague: isn't that what the rpi itself is? May 14 19:41:57 aholler: I think it would the first one of this kind May 14 19:42:10 and also the first hot swappable one May 14 19:42:47 the rtc subsystem should support that but I never tried :D May 14 19:43:09 I'm not sure, I think some people already using it that way. May 14 19:43:41 but I haven't found an usb-rtc-driver in the kernel May 14 19:44:06 so that would be something new to do. May 14 19:44:07 well, they haven't told me :D May 14 19:44:34 \r\t\c dongle May 14 19:50:36 not sure if it makes sense, using libusb is easier. May 14 19:51:43 but as kernel-driver the time would be available before userspace May 14 19:55:13 maybe prpplague wants to build a 5$ usb-rtc-dongle ;) May 14 19:55:38 * prpplague is tired of building boards for hobbyists May 14 19:58:16 heh May 14 20:01:27 my little sdr unit has a tiny pic for usb control of the onboard frequency synth. May 14 20:01:35 no rtc though May 14 21:08:50 99014614 May 14 21:08:58 oops sry May 14 21:09:18 thanks, is that your bank account? May 14 21:09:45 rsa token May 14 21:25:06 hmmmm, why doesn't my bank offer me the added security option o a rsa token May 14 21:28:48 sweet got my beaglebone online May 14 22:40:38 koen: Updated readme.htm for feedback: http://beagleboard.org/static/beaglebone/latest/README.htm May 14 22:49:41 jkridner: what is meant by "Two additional PRU signals overlaid with existing signals to the expansion header" for A6 ? Has pinout changed? May 14 22:52:21 some additional pins are brought to the same header pins. May 14 22:52:49 they are hi-z by default, so it shouldn't be a problem, though software will need to be careful not to drive them at the same time. May 14 22:53:11 existing code should work without changes. May 14 22:53:25 ok. does that affect the eeprom configuration code? May 14 22:54:36 we'll need to add extra fields. May 14 22:54:47 old revision eeproms won't enable these new signals. May 14 22:55:50 but the table has fixed length now, we'll have to invent something smart. or use the i2c positions. May 14 22:56:10 there is a version code. May 14 22:56:29 ah, forgot about that May 14 22:56:52 so no problem. May 15 00:35:24 So using this formula for GPIO1_2 May 15 00:35:32 32*1 + 2 May 15 00:35:34 is 34 May 15 00:35:46 but the pin is actually pin 5 on header P9 May 15 00:35:48 so wtf? May 15 00:35:51 Anyone can explain? May 15 00:38:14 https://github.com/CircuitCo/BeagleBone-RevA5/blob/master/BeagleBone_revA5_SRM.pdf?raw=true May 15 01:00:53 * prpplague throws old z80 chips at XorA May 15 01:01:12 those are pointy! May 15 01:03:07 prpplague: sweet :-D May 15 01:04:31 * ds2 carelessly throws Xilinx FPGA's around May 15 01:04:55 now you have to bake them out and straighten the leads. May 15 01:05:17 you can get a whole zx spectrum in a xilinx May 15 01:05:22 leads??? these are *ahem* BGAs May 15 01:05:27 I wish I had time to play with these toys May 15 01:05:44 too high-tech for me. May 15 01:08:57 zx81 is all you ever need :-D May 15 01:09:14 * XorA needs to learn PCB layout :-D May 15 01:09:44 XorA: :) there are several tutorials using eagle, but i recommend kicad, which also has a few tutorials May 15 01:09:55 * prpplague wishes he had time for all his projects May 15 01:10:23 just fyi, i am still looking for someone to take over the arduino-for-userspace-linux project May 15 01:10:39 prpplague: I am swithering between Veecad and laying out my own PCBs and paying 30E a shot for them May 15 01:13:03 XorA, why are you paying so much? do you need them quickly? May 15 01:13:25 Russ: becuase Im in the UK which sucks for prices May 15 01:14:08 dorkbot international shipping wouldn't be too bad May 15 01:14:44 60 isn't bad May 15 01:14:51 people are reporting that they get totally stung for import fees on PCBs :-( May 15 01:15:01 Russ: are you suggesting the 2-3 month turn around places? May 15 01:15:29 yes May 15 01:15:37 so was trying to stick within EU May 15 01:15:41 you just have to have patience May 15 01:15:43 Dorkbot is faster than that. May 15 01:15:51 its 3 weeks May 15 01:16:11 you can find $30 range places w/o the 2-3 month turn around if you look May 15 01:16:17 but that is US only May 15 01:16:30 dorkbot is a lot less than $30 May 15 01:16:39 but is it 2-3 month? May 15 01:16:40 and at lot less than 2-3 month May 15 01:16:45 3 weeks May 15 01:17:01 Im not actually that bothered by paying 30E May 15 01:17:23 if I design something sellable I can get signifficantly cheaper by ordering 20 or so anyway May 15 01:17:55 Russ: this is the dorkbotpdx stuff? May 15 01:18:30 ds2: Yes. May 15 01:18:31 yes May 15 01:18:44 They tend to have around a 3-week turnaround, and are stupidly cheap for boards. May 15 01:19:11 http://www.flickr.com/groups/oshpark/pool/with/6991077022/ May 15 01:19:22 the 4layer stuff looks interesting May 15 01:19:45 turn around was a bit longer for the 4 layer May 15 01:20:02 what's the advantage of dorkbot vs BatchPCB? May 15 01:20:15 the 2L stuff isn't that much cheaper May 15 01:20:36 emeb: Loads faster, and nicer boards. May 15 01:20:58 agmlego: cool - will check them out for my next project. May 15 01:21:02 ah.. I see the catch.. paypal only May 15 01:21:10 not a problem for me. May 15 01:21:33 wonder if he's willing to take credit cards via paypal May 15 01:21:46 How is PayPal only a catch? May 15 01:22:12 no reason to give paypal's grimy hands access to my account May 15 01:22:28 So just tie it to a credit card. May 15 01:22:32 besides, less risk with credit cards May 15 01:23:03 that breaks down the overall point of using a credit card to control risk May 15 01:23:17 Not really. May 15 01:23:33 does paypal itemize things on the CC statement? May 15 01:23:51 or do they do a xfer to paypal? May 15 01:24:16 Does your normal seller itemize things on your bill for a given transaction? May 15 01:24:23 Because nowhere I shop does. May 15 01:24:35 no May 15 01:24:35 oooh - 6mil line/space. May 15 01:24:43 can make things a bit tighter... May 15 01:24:46 ds2: So why is that even a question? May 15 01:24:57 I mean if I make 2 purchases, will I get 2 charges May 15 01:25:08 not itemize things down to individual items. May 15 01:25:25 if they make lumpsum xfers, it creates issues with disputes May 15 01:25:32 ds2: If you make two separate transactions, you will have two separate transactions, yes. May 15 01:25:57 agmlego: okay. do they show the vendor name in the transaction? May 15 01:26:23 ds2: Yes. May 15 01:26:53 A typical statement line will be something like "PayPal Transfer -- $vendor_name_here" May 15 01:27:05 fair enough. only issue is they didn't allow using a credit card only May 15 01:27:21 Who is "they"? May 15 01:27:26 they insist on getting their grubby little hands into your account then you can select CC funding May 15 01:27:27 Paypal May 15 01:27:32 you sure about that ds2? May 15 01:27:39 been through this last year May 15 01:27:39 No, you can set one up without an account. May 15 01:27:47 Always have been able to. May 15 01:27:52 that's a new feature May 15 01:28:00 you can use paypal without an accountt if you use a credit card May 15 01:28:04 Sure, you get a few more fees for things, and they remind you about the option to add an account. May 15 01:28:14 not if they recognize the cc # May 15 01:28:16 then how do you get around their verification thing? May 15 01:28:23 ut they allow you to have a PayPal account tied to a credit card only. May 15 01:28:28 What verification thing? May 15 01:28:47 if you are at your spending limit w/a non-premium account and they recognize the cc# you are screwed May 15 01:28:52 cuz they won't let me do anything w/o being a verified user and to become a verified user, they insist on getting access to my account. May 15 01:28:57 right May 15 01:29:02 i'm in the same boat May 15 01:29:16 ds2: They will not let you do anything...? Do go on. May 15 01:29:20 and my account -was- verified before, i just deleted the account details May 15 01:29:40 agmlego: yep. and I had money in the account too May 15 01:30:02 I still do not understand what issue you are having with it. May 15 01:30:17 agmlego: are you a US user? May 15 01:30:23 I use a cc only, but I had a defunct bank account linked several years ago May 15 01:30:37 ds2: Yup. May 15 01:30:54 agmlego: and you never game them a bank account, ever? May 15 01:31:09 ds2: For many years, yes. May 15 01:31:15 Without any issues at all. May 15 01:31:23 *shrug* May 15 01:31:55 agmlego: maybe you got grandfathered in or something May 15 01:31:58 paypal had some major "issues" when it was first getting started May 15 01:32:14 like trying to lock people out and keep their money May 15 01:32:14 I'd be okay if all they wanted was CC details. but that wasn't the case May 15 01:32:53 but I haven't heard of any confirmed cases of them doing that for many years now May 15 01:33:18 thurbad, or asking people to destroy works of art May 15 01:33:22 ds2: No idea. I know my roommate has only had her account for a year or two, and only has CC details in it. May 15 01:33:40 She does not actually have a bank account. May 15 01:33:52 http://techcrunch.com/2012/01/04/paypal-shreds-ostensibly-rare-violin-because-it-cares/ May 15 01:34:19 agmlego: donno May 15 01:34:20 Russ: Yeah, that was a bad one. But it is a pretty isolated incident. May 15 01:34:25 ds2: Me either. May 15 01:34:30 much rather not deal with them May 15 01:34:38 ds2: I suggest you contact them and figure out what the issue is. May 15 01:35:11 agmlego: got better things to do. if a seller doesn't want to take a direct CC, easier to decline May 15 01:35:35 Because accepting bare credit cards is a difficult and somewhat expensive task for a small company/single person, like DorkbotPDX. May 15 01:36:02 PayPal (or DWOLLA, or Square, or...) are far easier and cheaper. May 15 01:36:23 not really. they can have paypal accept it for them May 15 01:36:30 some seller will allow that May 15 01:36:44 be happy to pay extra for the fees May 15 01:37:18 You would be? May 15 01:37:25 Contact the seller directly and ask, then. May 15 01:37:30 Explain the situation. May 15 01:39:12 'k May 15 01:39:27 anyways... for 2L boards, that isn't that great of a price May 15 01:40:39 On the other hand, they are nice boards and have a pretty fast turnaround. May 15 01:41:31 for 2L boards, there are places quoting 3.30/sq inch May 15 01:41:59 And what kind of turnaround time, and board quality? May 15 01:42:05 8D May 15 01:42:06 Also note that shipping is free. May 15 01:42:40 dorkbot's page says $5 for shipping May 15 01:43:06 Eh? May 15 01:43:16 anyways..back to chips and dogs ;) May 15 01:43:39 agmlego: dorkbotpdx.org/wiki/pcb_order... under Who's eligible May 15 01:43:54 n/m May 15 01:44:02 that's international May 15 01:44:04 ds2: Only international shipping. You are a US customer (I assume, from what you said above), so shipping would be free. May 15 01:44:58 in anycase, the 4L's is the one of interest. 2L has lots of folks May 15 01:45:15 ds2, my 4 layer order went well May 15 01:45:36 Russ: how long did it take? May 15 01:46:04 lets see, order went in apr 3 May 15 01:46:18 ds2: Also, his board tolerances are smaller than a lot of places I have seen. May 15 01:46:34 agmlego: you mean the 6/6 stuff? May 15 01:46:37 and I think they came in sometime at the end of apr May 15 01:46:39 Yeah. May 15 01:46:47 gold flashing too May 15 01:46:49 Most places I have looked at did 8/8 or 10.10 May 15 01:46:53 that's not too unusual May 15 01:47:02 now if he did 4/4, he'd have me sold May 15 01:47:13 Russ: Most of the time. I have had a few boards come in with silver contacts, but they are usually gold. May 15 01:47:28 ds2: Ask him, he may run a finer board. May 15 01:47:30 Russ: that's not bad May 15 01:47:35 true true, the finish is subject to change May 15 01:48:02 agmlego: *nod* May 15 01:48:28 * agmlego goes to take a shower May 15 01:49:32 compiling mysql for the bone takes for freaking ever! May 15 01:49:32 lol May 15 01:52:59 er your compiling on the bone? May 15 01:53:06 *you're May 15 01:53:14 Yea May 15 01:53:50 I didn't want to bother with setting up a more powerful debian box to compile on it. May 15 01:59:56 Loving the bone so far. May 15 02:00:01 Great little device. May 15 02:00:09 Boots quicker than I expected. May 15 02:01:44 Does anyone know if it is possible to change the pull-down resistors on certain pins to pulluos? May 15 02:01:48 pullups? **** ENDING LOGGING AT Tue May 15 02:59:59 2012
