**** BEGIN LOGGING AT Mon Jan 13 02:59:59 2014 Jan 13 03:30:10 hi Jan 13 03:30:43 BBB can use HDMI 1.4V 9ft cable? Jan 13 03:38:03 I am running the ubuntu distribution proivded by armhf.com. When I cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq I get 300MHz. How can I change the CPU speed to 1GHz? Jan 13 03:41:11 Has anybody here implemented SLAM on any platform? Jan 13 03:47:56 zump .. you'l probably find that it does it automaticcaly with cpu load Jan 13 03:48:08 veremit: i see Jan 13 03:48:13 look for a process/system called cpufreqd Jan 13 03:48:26 if it ran 100% at 1Ghz .. it would likely fry itself :) Jan 13 03:49:07 so, like most modern processors it self-regulates Jan 13 03:49:31 i dont see a cpufreqd... Jan 13 03:49:48 probably built into the kernel Jan 13 03:50:06 I got cpufrequtils and set it to 1000MHz.. should i undo that? Jan 13 03:50:32 it's unlikely to remain persistent .. personally wouldn't recommend it Jan 13 03:50:59 you'd need to unload the 'ondemand' governor for cpufreq Jan 13 03:51:29 i dont think it will work correctly because the driver said generic_cpu o.O Jan 13 03:51:42 no .. I shouldn't imagine so :) Jan 13 03:52:04 theoretically yes . but the operatins may not be exposed for cpufrequtils Jan 13 03:52:23 also, my sd card i/o is really quite slow. anything help with that? Jan 13 03:53:06 it can depend a lot on what brand SD card you have Jan 13 03:53:53 its a bit of a known issue with the Pi/Beagle/etc community .. more so the Pi because the OS is held on a SD card Jan 13 03:55:20 heres a bit of an in-depth explanation of cpufrequency scaling .. http://www.ibm.com/developerworks/linux/library/l-cpufreq-1/index.html?ca=dgr-lnxw16LinuxPowerP1&S_TACT=105AGX59&S_CMP=grlnxw16 Jan 13 03:56:16 not th ebest though .. Jan 13 04:02:57 how can i open a file in bash and keep it open ? (this is for the watchdog timer) Jan 13 04:03:11 tail -f ? Jan 13 04:04:35 true.. but i also need to write to it every 59 seconds to keep the watchdog happy Jan 13 04:04:57 shouldn't matter .. open another shell :) Jan 13 04:20:22 veremit: I get tail: error reading `/dev/watchdog': Invalid argument. any ideA? Jan 13 04:20:33 oh lol ok Jan 13 04:21:10 maybe you can't do that then .. possibly not read access Jan 13 04:21:51 not really used the watchdog on arm cpus Jan 13 04:26:02 veremit: i think this will work http://pastebin.com/UUy0sQXm Jan 13 04:27:04 looks ok to me Jan 13 04:28:35 do u think sleeping will let it be preempted or is it blocking Jan 13 04:28:47 couldn't say Jan 13 05:03:53 Are any of you familiar with installing Debian on a BBB? Jan 13 05:04:08 moderately Jan 13 05:05:15 I just use the method at http://eewiki.net/display/linuxonarm/ Jan 13 05:05:36 ok.. the BBB page there :) Jan 13 05:07:40 Hmm. I'm trying to follow the directions here: http://elinux.org/BeagleBoardDebian#eMMC:_BeagleBone_Black. But it's not exactly straightforward Jan 13 05:07:59 lol .. no I saw those .. and its not Jan 13 05:08:18 On that page you linked, should I use the "small flash" or the regular method? Jan 13 05:08:34 I've used the regular image .. its not that big Jan 13 05:08:39 debian 7.3 iirc Jan 13 05:09:32 I think building the debian image is more than people can cope with normally Jan 13 05:09:43 so using RN's is much simpler Jan 13 05:10:33 Alrighty. Jan 13 05:11:00 Now, it says to use wget to get the image Jan 13 05:11:03 note the footnotes on that page .. I usually slip up lol Jan 13 05:11:14 mhmm? Jan 13 05:11:24 should I be doing that from the board or should I download it on to my computer and then move it to the board? Jan 13 05:11:49 personally .. if you got a uSD spare .. I severely doubt you'll fit it all on the beagle itself Jan 13 05:13:35 I think the instructinos are for linux on the PC .. so if you're under windows .. you might find it harder Jan 13 05:18:37 yessss Jan 13 05:18:43 beaglebone black just arrived by delivery Jan 13 05:19:19 i couldn’t find one and had to resort to hacking up a raspberry pi to fit in a BBB specific space Jan 13 05:19:31 only to find that i2c on raspberry pi is broken Jan 13 05:19:54 * TehCaptain should refrain from IRC while under the outrageous infulences of alcohol Jan 13 05:20:08 no drunk irc is good Jan 13 05:20:13 reduce teh overall level of pedantry Jan 13 05:20:14 'gratz john Jan 13 05:29:30 after loading some pru code in to my beaglebone it froze up, and now won't boot (3 of the user leds are solid on) Jan 13 05:34:03 I'm currently reformatting my USB. In case you go to sleep, thanks a bunch veremit. Jan 13 05:34:18 good luck! Jan 13 06:24:37 3M HDMI cable can use the beaglebone black? Jan 13 06:28:44 hello? Jan 13 06:30:14 ee33, hello ... irc rules are simple, ask you question (clearly as possible) Jan 13 06:31:41 then from the one that sleep to the one that have build the stuff you are coming in the chan for will try to help you to find your way. (I am not one of the Beagle builder, but I am interested in it as user) Jan 13 06:49:21 good comments, i have lots to learn: http://hackaday.com/2013/12/07/speeding-up-beaglebone-black-gpio-a-thousand-times/ Jan 13 07:15:51 johnwalkr: exactly, learn to ignore that Jan 13 07:16:06 and use pru you mena? Jan 13 07:16:23 johnwalkr: whoever tells you to poke /dev/mem directly is plainly wrong (at least when the topic is kind of driver/peripheral programming) Jan 13 07:16:46 well the comments are more interesting than the post Jan 13 07:17:25 the pru is an option. or writing a proper kernel module (though that will hit a boundary also somewhere near that value) Jan 13 07:18:28 none of the arm systems are really designed for high-speed gpio access Jan 13 07:19:16 using a properly set up pwm you can maybe go up further Jan 13 07:19:29 if you want that .. code a separate micro-controller, and interact with it via serial/i2c/etc buses Jan 13 07:20:24 a computer has always been for interconnecting peripherals Jan 13 07:20:36 not to say that it can't do other things Jan 13 07:21:01 that’s what i’m doing now (i2c) but in some instance i might want something more direct Jan 13 07:21:07 it depends on what you need to do Jan 13 07:21:20 the pru is interesting though Jan 13 07:21:29 never knew about it 'til I came here Jan 13 07:22:00 anyhoos's time to shower & get ready for work .. bbl possibly :) Jan 13 08:34:09 i want to know will i get a sd card loaded with linux.? Jan 13 08:34:56 sure. send 1337.37$ to a swiss number bank account of my choice and i will send you one. Jan 13 08:35:35 no thanx i can buy one without that... Jan 13 08:35:54 well then why did you ask? :) Jan 13 08:36:04 i just wanted to know will i get a sd card or not. Jan 13 08:36:12 how shall we know? Jan 13 08:36:27 we do not even know what you are talking about.... Jan 13 08:36:38 (besides the sd card.) Jan 13 08:36:54 beagleboard? beagleboard XM? beaglebone? beaglebone black? Jan 13 08:37:11 if you really want to help, just tell a trusted website from where i can buy a beaglebone black.? Jan 13 08:37:56 http://beagleboard.org, about 600px down, click "Select a distributor to buy" Jan 13 08:38:15 those are the officially "trusted websites" Jan 13 08:39:04 the available distributors for the country i am in, give the same beaglebone black at different prices. Jan 13 08:39:10 how that can be so? Jan 13 08:39:16 and the beagleboard black specifically comes *without* sd card, by the way Jan 13 08:39:31 ask them. probably one wants to make more profit than the other. Jan 13 08:39:49 oh that's the case. Jan 13 08:40:12 cool enough Jan 13 08:40:23 then i will check.. Jan 13 08:45:34 has anyone configured thier BBB to have 2 usb host ports? Jan 13 08:57:34 LetoThe2nd: i'd rather use 1337.37CHF Jan 13 08:57:52 LetoThe2nd: it's the more stable currency, and swiss banks like it more than this weird thing :) Jan 13 10:42:02 Hi all, anyone knows if this year beagleboard.org will enroll in the GSOC2014 programme? Jan 13 10:50:43 I think we will Jan 13 10:51:02 interested? Jan 13 10:52:43 hmm Jan 13 10:53:01 can this setup script not be run from the BBB (when booted to sd card)? Jan 13 10:53:02 http://elinux.org/BeagleBoardUbuntu#Saucy_13.10 Jan 13 10:53:26 following the directions but it says it can’t find /dev/mmcblk1 Jan 13 10:53:35 then it shows the output of fdisk which definitely shows /dev/mmcblk1 Jan 13 10:54:39 this is so frustrating. i normally use the images from elinux.org that just use dd, but the current one is broken right now Jan 13 10:55:10 Yes I am, I'm asking now because i have no prior experience with beagle board enviroment and I want to have time to prepare myself before admissions start. But I am definetly interested. Jan 13 10:55:29 errr not from elinux, from armhf Jan 13 11:01:45 Nooze: ok Jan 13 11:05:01 oh well, i’ll just use the flasher image i guess Jan 13 11:09:17 johnwalkr: it could be that at the time, when the init script is run, that the sd card is not yet detected Jan 13 11:09:40 KotH: your doing beagle supoort? Jan 13 11:09:42 johnwalkr: ie, run the init script as the last script and let it loop for 2-3 seconds Jan 13 11:09:48 mrpackethead: once in a while Jan 13 11:53:14 cant seem to get my lcd working with my beaglebone black. i think it uses a display resoltion which the lcd can't display, but i dont know how to change this with only ssh access Jan 13 11:53:45 what lcd? Jan 13 11:55:39 G104V1-T01 Jan 13 11:56:24 i connected the lcd_data lines to the TTL interface of the display Jan 13 11:56:42 it's not cape-based Jan 13 11:57:02 and how did you tell the BBB about this LCD? Jan 13 11:57:19 i added to uEnv.txt this: video=HDMI-A-1:640x480M@60e Jan 13 11:58:24 and this LCD uses the HDMI timing? Jan 13 11:58:32 i cant see any boot console onscreen, but sometimes, i can see the gnome desktop flickering like crazy, because it seems to switch to 1024x768, which is too much for the lcd Jan 13 11:58:55 by itselft it should not switch to 1024x768 Jan 13 11:59:03 i dont know. what i know it that it uses 640x480@60ht Jan 13 11:59:05 *hz Jan 13 11:59:14 you need to check the timing values Jan 13 11:59:33 and then prepare a correct DT overlay file Jan 13 11:59:41 look at the LCD capes and their DT file Jan 13 11:59:43 files* Jan 13 11:59:48 and adjust the values Jan 13 11:59:54 with correct timing Jan 13 11:59:58 see line 100: http://pastebin.com/Hspn6MDC Jan 13 12:00:26 what dt file? can you elaborate pls? Jan 13 12:01:48 http://elinux.org/BeagleBone_and_the_3.8_Kernel Jan 13 12:04:11 this looks complicated. will read now Jan 13 12:05:42 I have no idea how this video=HDMI-A-1:640x480M@60e works Jan 13 12:06:08 maybe forcing VGA for hdmi is enough Jan 13 12:08:51 the thing is, that the hdmi framer uses the lcd_data pins for input, so the idea is to enable the hdmi, so i can grab the lcd_data lines Jan 13 12:09:31 my first try was to use xrandr over ssh, but it is always outputting "can't open display" Jan 13 12:10:09 as if there were no displays at all, which is ok, since the bone can't detect if something is attatched to the lcd_data lines Jan 13 12:10:56 it can detect if there is something on the HDMI connected Jan 13 12:11:16 its all all about automatic discovery with EDID and such Jan 13 12:12:21 yea sure, but actually there is nothing connected to the hdmi interface, so the bone thinks there is no display Jan 13 12:12:27 indeed Jan 13 12:12:35 thats the reason edid discovery fails Jan 13 12:12:45 so i have to force it somehwo Jan 13 12:12:46 hence my proposal to create a DT overlay as if you had a cape Jan 13 12:12:56 and tell the kernel to load it at boot Jan 13 12:13:37 do you have a simple example of a lcd cape dt overlay? Jan 13 12:13:56 I dont Jan 13 12:14:02 but google should find you one Jan 13 14:24:33 anyone using a beaglebone as an wifi access point? Jan 13 14:32:59 a couple of people are Jan 13 14:44:19 Hi guys Jan 13 14:47:39 Do you know anything about backlog for BeagleBone Black? Jan 13 14:48:19 what would such a backlog log back? Jan 13 14:48:57 There is no BBB anywhere? Jan 13 14:49:01 There is no BBB anywhere Jan 13 14:49:08 there are BBB everywhere Jan 13 14:49:17 I checked Digikey, Arrow, Jameco Jan 13 14:49:20 just too many people buying them Jan 13 14:49:23 They don't have it Jan 13 14:49:37 cco is building them as fast as they can Jan 13 14:50:00 people just bought too many over christmas Jan 13 14:50:06 Where I can buy it? Or just place order and wait? Jan 13 14:50:14 i guess it will normalise during this month or in feb Jan 13 14:51:03 Ok, I hope so Jan 13 14:51:45 Digikey even didn't specify how long is backlog Jan 13 14:52:31 Jameco (AFAIR) says it's 26 weeks Jan 13 14:53:07 Thank you for info though Jan 13 15:02:16 KotH, martin luther king holiday rush is hitting now..they may never be able to stock enough BBBs Jan 13 15:03:21 oh damn! Jan 13 15:03:24 we are all doomed! Jan 13 15:04:41 then valentine's day (hot gift for2014)...st. patricks day.. Jan 13 15:04:46 supply can't possibly keep up Jan 13 15:05:25 you ruined my day Jan 13 15:05:41 * Sundiver is sobing Jan 13 15:07:16 april fools day sale...good friday...earth day! Jan 13 15:07:31 then...christmas in july! Jan 13 15:07:36 fly out to Dallas, Microcenter here has 2 in stock Jan 13 15:07:44 ;) Jan 13 15:08:10 it's clearly hotter than xbox one or ps4 even Jan 13 15:08:59 carpman, I should come get those to be sure I have them for Mother's Day Jan 13 15:09:41 indeed Jan 13 15:09:52 Local Microcenter has 2 in stock Jan 13 15:10:15 carpman: thank you for idea Jan 13 15:10:24 microcenter rocks :) Jan 13 15:10:43 yup Jan 13 15:10:56 carpman, my microcenter also has them in stock..although the MC price is $50 Jan 13 15:11:36 mdp: as with most things you pay for the convience of being able to drive over and get it right then. They carry PLA and ABS fillament too, little more expensive but worth it if you need it right then. Jan 13 15:12:40 carpman, indeed..though nothing is convenient to me here. ;) 50 minutes to my MC Jan 13 15:13:10 yeesh, thats quite a drive Jan 13 15:13:52 carpman, have to go to the big city Jan 13 15:14:30 speaking of..one of the closer radioshacks has it in stock Jan 13 15:14:40 for $89.99 Jan 13 15:14:45 lol Jan 13 15:14:45 can anyone answer how to fix the problem given in the following link Jan 13 15:14:49 https://groups.google.com/forum/#!topic/beagleboard/R0NqjS5FMgs Jan 13 15:14:56 it comes with a 2 year 4g contract! Jan 13 15:16:28 mdp: ah, that lovely makershed kit Jan 13 15:17:09 yeah, "Getting Started with BeagleBone" Jan 13 15:17:25 the RPi kit they sell is $129.99! Jan 13 15:29:03 dirty dirty u-boots Jan 13 16:27:07 has anyone put together a driver or userland program to interface with an nrf24l0+ for the BBB? Jan 13 16:27:19 I've searched around not found anything Jan 13 16:31:05 Rickta59: uhmm... all you need is a kernel driver Jan 13 16:31:12 Rickta59: nothing bbb specific Jan 13 16:31:27 Rickta59: userland should be "easy" to write if it doesnt exist yet Jan 13 16:31:44 sure, i just don't want to write it if it has already been written Jan 13 16:32:37 and when I asked about a BBB one, I meant one that setups SPI with the DT and such Jan 13 16:34:34 well, that's trivial to write Jan 13 16:35:20 hmm.. i dont see any linux driver Jan 13 16:35:26 could be that you have to do spi from user space Jan 13 16:35:37 shouldnt be too difficult anyways Jan 13 16:35:51 it could be trivial or it could be a lot of work depending on what level you take it to Jan 13 16:36:03 if you write a kernel network driver i wouldn't call that trivial Jan 13 16:36:04 writing DT is trivial Jan 13 16:36:14 doing SP from user space is easy too Jan 13 16:36:20 SPI* Jan 13 16:36:39 writing a simple character driver is trivial as well Jan 13 16:36:59 it can be some work, but it's not rocket science Jan 13 16:37:12 did i say it was rocket science? Jan 13 16:37:14 jeez Jan 13 16:37:21 just asking .. Jan 13 16:37:25 but i wouldnt write a driver for an 2.4GHz ISM module that doesnt do 802.15.4 Jan 13 16:38:25 the easiest thing is just to take a thing working on an mcu+nrf and use that .. i thought others might have got inspired to show off their BBB skills Jan 13 16:38:52 if you have mcu code, then writing an linux app that does the same is trivial Jan 13 16:39:09 if you used a sane api on the mcu, then it's a simple search and replace Jan 13 16:39:16 (mostly) Jan 13 16:40:21 and showing of bbb skills.. there are no bbb skills. it's just an embedded linux system. there is nothing special about the bbb at all Jan 13 16:41:02 ok thanks for your input Koth .. so no is the answer from you Jan 13 16:41:42 i havent found a linux driver, but i have not looked whether there is any example code Jan 13 17:04:46 * qlex says hi Jan 13 17:05:59 i was browsing around for a project on beaglebone(beagleboard) that would allow GPIO control/use and also allow other sensors automation (sensors connected to beagle using modbus) Jan 13 17:06:07 is there any1 that would have knowledge on this ? Jan 13 17:06:24 something similar to this (for Raspi):http://code.google.com/p/webiopi/ Jan 13 17:08:22 qlex: linux is linux, that webiopi should work prefectly fine on beagle with some tweaks Jan 13 17:09:53 why is there no apt-get, only opkg? when comparing Rpi and beagle, i can see that even setting static ip is more complex than just editing interfaces file.. Jan 13 17:10:39 prpplague: couldnt find any info on using modbus (apart from pymodbus experimental stage) - so that i could control Moxa devices through python interface on beagle Jan 13 17:10:59 was hoping i could get in touch with someone that does "home automation", using beagle and python Jan 13 17:11:09 qlex: did you find information on using it with RPi? Jan 13 17:13:13 havent searched.concentrated on beagle, as this is what my clients wants to use Jan 13 17:14:47 qlex: as i have said: linux is linux Jan 13 17:15:06 qlex: if you find it for one, it generally works on any linux Jan 13 17:15:21 qlex: you don't have to limit your searches specifically for beagle Jan 13 17:15:55 ok, can you tell me why is beagle so much different in terms of its linux ? Jan 13 17:16:09 im used to apt-get, used to using /etc/network/interfaces Jan 13 17:16:26 webiopi uses dev mem so it would take some porting to work on other hardware Jan 13 17:16:27 here on beagle, it took me 2 hours to figure out i need to use /usr/lib/connmod/test scripts for it Jan 13 17:17:09 jackmitchell: exactly - that what my engineer said Jan 13 17:21:06 qlex: it isn't different, what is different is the linux distro that is installed, you can install whatever you want Jan 13 17:21:29 qlex: each linux distro will have various features and options, but in general the functionality is the same Jan 13 17:23:25 ok, so its angstrom that's so much different than raspian Jan 13 17:23:31 strange, as both come from debian ? Jan 13 17:23:47 angstrom came from openembedded, not debian Jan 13 17:24:08 qlex: if you are more interested in a debian like build try the beta releases of robert nelsons debian image Jan 13 17:24:18 qlex: if you have someone who is interested enough the backend could probably be ported to use libsoc which looks like it supports most of the features webiopi uses Jan 13 17:28:06 client needs that angstrom distro Jan 13 17:28:13 doesnt want to use beta or non-stock Jan 13 17:29:01 jackmitchell: backend of webiopi needs to use libsoc - and currently its using what ? Jan 13 17:29:30 qlex: it currently uses it's own implementation of a hardware api Jan 13 17:29:42 since beagle has more GPIO/expansion ports, i was hoping to find some python with web interface alreayd existing Jan 13 17:29:46 that we could build upon Jan 13 17:30:02 qlex: just replace that rpi only hardware api, with generic libsoc linux hardware api Jan 13 17:31:15 the application might make some assumptions on what hardware is available however, so there would be some more work Jan 13 17:32:15 anything similar to webiopi on beagle out there? Jan 13 17:32:34 I don't think so Jan 13 17:32:38 i was browsing through 300+ projects on beagleboard.org, some of them on home automation, but havent found anything interesting yet Jan 13 18:19:14 Bonjour ! Jan 13 19:16:41 What Bluetooth dongles are compatible with the BB? Jan 13 19:17:34 Actually I meant compatible WiFi dongles... Jan 13 20:32:27 I'm on my daily hunt for a shop selling BBB in UK out Europe, anyone seen any? Jan 13 20:34:17 smssms: farnel just received another large shipment Jan 13 21:17:58 so i finally got my lcd working with the beaglebone black over the lcd_data lines, but i have a strange issue: it seems that every horizontal line is shifted by one pixel to the right, resulting in the overflow pixel to be shown on the left side one line down. any suggestions?
