**** BEGIN LOGGING AT Tue Aug 13 03:00:00 2013 Aug 13 03:00:22 no i undertand what, but the FAQ was saying to xz -cd ./ubuntu-13.04-armhf-minfs-*.img.xz > /dev/sdb Aug 13 03:00:35 ohhhh...ubuntu. Aug 13 03:00:53 my bad. i thought you were talking about angstrom. Aug 13 03:01:00 =( Aug 13 03:01:53 http://elinux.org/BeagleBoardUbuntu#eMMC:_BeagleBone_Black says it's the same process. Aug 13 03:02:05 put image on sd, sd image flashes emmc Aug 13 03:02:45 so i put the image on the sd NOT from the BBB, i think i was confusing that part Aug 13 03:02:53 if there's a valid image on the emmc, it'll boot from emmc even if there's an sd card (you have to hold down s2 to make it boot from sd) Aug 13 03:03:08 i don't know what you're saying Aug 13 03:03:48 i was going to boot from BBB on emmc Aug 13 03:04:12 that's what that link describes. Aug 13 03:04:14 download img, put it on microsd, reboot to microsd then flash emmc Aug 13 03:05:02 close enough. Aug 13 03:05:16 second and third sentence of that link. Aug 13 03:05:47 i understand now ;) Aug 13 03:06:13 coo Aug 13 03:21:48 nomel you only need to hold S2 down if there is not suitable uEnv.txt override. Aug 13 03:21:54 wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee Aug 13 03:21:55 is no suitable* Aug 13 03:22:01 DT free kernel boots on BBB! Aug 13 03:22:13 which version ? Aug 13 03:22:15 ds2: die! Aug 13 03:22:17 3.2 ? Aug 13 03:22:18 3.2 Aug 13 03:22:19 :D Aug 13 03:22:48 cool Aug 13 03:23:00 you happy about that ? becaue i kind of like dt :P Aug 13 03:23:03 might need to backport patches Aug 13 03:23:09 DT is a waste of space Aug 13 03:23:15 but I like working on smaller chips Aug 13 03:23:56 I like the fact that i dont have to recompile the kernel for *some* "drivers" Aug 13 03:24:28 * mranostay tattoos UEFI and ACPI on his knuckles Aug 13 03:24:29 i recompile so often though so it probably wouldnt be very important Aug 13 03:24:31 you can do that w/o DT Aug 13 03:24:57 as module sure Aug 13 03:25:06 depends on what drivers Aug 13 03:25:10 which yeah dt kind of replaces in some cases i guess ? Aug 13 03:25:12 which ones are you thinking of? Aug 13 03:25:21 ds2: why the hate for DT2? Aug 13 03:25:23 well mostly i just mean pinmuxing Aug 13 03:25:25 *DT Aug 13 03:25:28 space Aug 13 03:25:35 too much bloat Aug 13 03:25:49 the DT method of pinmuxing is braindead Aug 13 03:25:57 you might as well pinmux in u-boot Aug 13 03:26:45 i guess, but luckily for me im not used to the "old way" Aug 13 03:27:51 mostly i've been finding stuff i need, i have to recompile anyhow so yeah kind of a moot point Aug 13 03:28:05 namely when i have to staticaly compile modules into the kernel Aug 13 03:29:24 barring actual code changes, there isn't that much of a need to recompile... so *shrug* Aug 13 03:29:32 and I do static kernels Aug 13 03:31:57 that ds2 - he's so manly! Aug 13 03:33:06 * mranostay hurls ACPI5 around the room Aug 13 03:33:19 Ewwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww ACPI Aug 13 03:33:22 * emeb_mac ducsk Aug 13 03:33:28 ducks Aug 13 03:33:32 geese Aug 13 03:33:41 no going away :P Aug 13 03:33:44 *not Aug 13 03:36:12 why is the Saleae Logic so expensive? Aug 13 03:37:21 not #sigrok oops :) Aug 13 03:40:01 cause of that bitchin' machined aluminum case Aug 13 03:40:12 and the rad little clips. Aug 13 03:40:14 ds2, then perhaps you know something i dont :) Aug 13 03:40:22 whcih is seriously very likely Aug 13 03:40:35 * m_billybob is still newb Aug 13 03:41:24 giving a talk about sigrok at ELCE Aug 13 03:41:34 wtf is sigrok lol Aug 13 03:41:54 keep hearing you all talk about it and im clueless Aug 13 03:42:00 m_billybob: oss logic analzyer sw Aug 13 03:42:20 oh kind of lime black magic probe ? Aug 13 03:42:24 works with a lot of LA/scopes/DMMs as well Aug 13 03:42:26 err not thats somethign else Aug 13 03:42:50 geeky EE stuffs ;) Aug 13 03:43:16 * m_billybob goes back to his codemonkey corner Aug 13 03:43:35 * mranostay wonders when RLE was borken Aug 13 03:43:54 i don't want to have to carry a Rigol 1052 for a demo :P Aug 13 03:44:17 is that a scope ? Aug 13 03:44:25 yes Aug 13 03:44:30 i like my OLS Aug 13 03:44:37 know the namebrand just not the model number Aug 13 03:44:48 got debian on the BBB ;) Aug 13 03:44:57 seems hdmi doesnt work by default tho, boooo Aug 13 03:44:59 cool welcome to theclub. Aug 13 03:45:01 m_billybob: er Rigol isn't a name brancd? Aug 13 03:45:19 sure is just didnt recognize the model number mranostay Aug 13 03:46:02 DS1052E Aug 13 03:46:11 100Mhz ? Aug 13 03:46:16 50mhz Aug 13 03:46:33 which is modable to 100Mhz through softwre iirc Aug 13 03:46:51 could be thinking of a different model Aug 13 03:46:52 yes not bricking unless i need to :P Aug 13 03:47:08 need to downgrade firmware and do the magic commands Aug 13 03:47:25 yeah god old dave had a video on it Aug 13 03:47:31 good old dave* Aug 13 03:47:40 he can be god you don't know Aug 13 03:47:52 maybe lol Aug 13 03:48:29 m_billybob: i know these things. Aug 13 03:48:37 we have a couple of older 400Mhz HPs here so moot for us. but i leave alll of that EE monkery to wulf my buddy Aug 13 03:49:46 he seems to like his old old tectroniks ( or some such ) scope Aug 13 03:51:03 man, i still see people recommending "a good analog scope" to newbies in electronics, that want to work with microcontrollers and whatnot. Aug 13 03:51:19 wtf is the point of a non-persistent display if you have a non-repeating waveform? Aug 13 03:51:44 with the state of logic analyzers what is the point of a ful blown scope now days ? Aug 13 03:52:03 unless you need analog no point Aug 13 03:52:30 a logic analyzer and a scope are really used for different things these days Aug 13 03:52:32 all i remember was trying to decode the data from my credit card magstripe with my analog scope....ended up making a camera hood out of cardboard and spending 15 minutes trying to catch the waveform with my shitty camera Aug 13 03:53:04 pity that sigrok scope support is still not that great Aug 13 03:53:17 I think for most thigns id need one or the other for a logic analyser would work Aug 13 03:53:18 but LA support is really good Aug 13 03:53:49 or if i did need a scope id need somethign that would cost as much as a new car Aug 13 03:54:23 Russ: patches are welcome :) Aug 13 03:54:38 I was really hopeful about adding support for this http://www.gabotronics.com/development-boards/xmega-xprotolab.htm to sigrok Aug 13 03:54:56 but I didn't want to go and code all the oscilloscope support and clients for sigrok Aug 13 03:55:59 and of course a sigrok scope using the advanced adc features that am335x can provide would be cool Aug 13 03:56:20 * mranostay whistles Aug 13 03:56:23 sounds interresting Aug 13 03:57:37 -> /. + HaD exact steps# BBB + PRU == osc scope + LA heh Aug 13 03:57:43 oh wait thatwouldnt work Aug 13 03:57:56 we'd have to work rpi and / or arduino in there somewhere Aug 13 03:57:58 m_billybob, read the adc section of the trm, you'll get the idea Aug 13 03:58:03 it has triggers and what not Aug 13 03:58:38 the pwmss section is interesting too as it can provide cool features too, such as timing between pulses, etc Aug 13 03:59:03 Russ, are you workign somethign along those lines into your project ? Aug 13 03:59:11 I don't have time for that :p Aug 13 03:59:13 Russ: ecap? Aug 13 03:59:31 is that pig latin for cape? Aug 13 03:59:43 heh Aug 13 04:02:15 i remember sometime ago someone made a LA out of a stellaris launchpad Aug 13 04:02:20 i thought that was pretty cool too Aug 13 04:03:32 but yeah those have no where near the processing power, or features Aug 13 04:13:03 (but yes, eCAP http://processors.wiki.ti.com/index.php/AM335x_PWM_Driver's_Guide#eCAP) Aug 13 04:13:58 Russ: don't post nerd porn here! :P Aug 13 04:18:56 whats the max pwm freq on beaglebone Aug 13 04:19:21 beaglebone black, i mean Aug 13 04:19:47 half sysclock? Aug 13 04:20:13 anyone actually test it? Aug 13 04:21:55 was on a RPi and printing a specific image took 21 seconds, got BBB running and it prints in 10 seconds. perfect!!! Aug 13 04:22:03 ordering 20 BBB's ;) Aug 13 04:24:08 funkster: what are you printing to? Aug 13 04:24:23 a dye sublimation printer Aug 13 04:25:35 a photo printer. Aug 13 04:28:08 what case do you guys have for the BBB? Aug 13 04:29:00 cool i figured it would work better / faster Aug 13 04:29:25 funkster: there is a company, quick logic or some such that has a very nice metal case Aug 13 04:29:30 let me see if i can find the url Aug 13 04:29:46 m_billybob: yup yup! prog a combination of the faster processor and the drive being faster Aug 13 04:30:02 prpplague there seems to be another too, laser cut plastic. someone posted an image on the groups a few days ago Aug 13 04:30:18 well im assuming the manufactuer did Aug 13 04:31:01 m_billybob: yea i am not a fan of those Aug 13 04:31:07 they're all fairly reasonably priced all ive seen so far areunder $20 Aug 13 04:31:12 me either but it wasnt bad Aug 13 04:31:31 I like the black metal case the best so far i think Aug 13 04:31:34 https://www.logicsupply.nl/cases/mini-pc-cases/bb100/ Aug 13 04:31:59 yeah thats the one i like Aug 13 04:32:30 wonder what US prices _ shippign would be on those Aug 13 04:32:41 prices + shipping* Aug 13 04:32:42 100 billion dollars Aug 13 04:32:51 somewhere over $20 each Aug 13 04:33:00 ( most likely ) Aug 13 04:33:24 mranostay ok no more austin power for you !

Just bought a wireless double from ebay and it has not arrive yet. Aug 13 05:32:04 where where? Aug 13 05:32:34 you dont need Wireless.. the USB will give you a TCP connection after you install the serial driver Aug 13 05:32:51 http://beagleboard.org/latest-images Aug 13 05:33:02 yup Aug 13 05:33:10 really. wow. amazing. Aug 13 05:33:25 I didn't know USB can do TCP/IP connection. Aug 13 05:33:31 weird. Aug 13 05:33:34 how so? Aug 13 05:34:14 well.. lets just say its magic :) Aug 13 05:34:44 so I can talk to it via: http://192.168.7.2 Aug 13 05:34:49 without ethernet?

Aug 13 05:58:07 ok.. try to ssh in 192.168.7.2 Aug 13 06:00:17 just so you know this is a brand new beaglebone from a ESD bag. Aug 13 06:00:29 do we need OS to run this webserver or ssh server? Aug 13 06:01:49 heheheh? why did you buy Beaglebone? Aug 13 06:02:24 because I want to compare it with my pi. Aug 13 06:02:38 so you know PI? Aug 13 06:02:50 yeah. Aug 13 06:03:07 I got a Raspberry Pi. Aug 13 06:03:40 did the XP detected BBB this time? Aug 13 06:04:01 let me check device manager Aug 13 06:05:03 I got a problem while booting into the beagleboard-xM i am using tisdk with tht while login console is not coming, Aug 13 06:05:22 serial console saying to uninstall some of the packages with GLPv3 Aug 13 06:05:22 let me try a different USB port. Aug 13 06:06:48 nope. Aug 13 06:06:52 no go with SSH Aug 13 06:07:14 I am putty and attemp to ssh in to it via the magic usb connection but no go. Aug 13 06:07:14 hmm Aug 13 06:07:45 do you see the "BeagleBone" volume mounted on ur machine? Aug 13 06:08:00 nope Aug 13 06:08:31 there should be a volume call "BEAGLEBONE" that should mount Aug 13 06:09:00 Computer Management Aug 13 06:09:30 I check Disk Management and I do not see any volume call "BEAGLEBONE". Aug 13 06:09:51 hmm Aug 13 06:10:00 do you have micro HDMI? Aug 13 06:10:11 let me hit the reset button. Aug 13 06:10:14 on BBB. Aug 13 06:10:14 you may need to have display.. check out whats going on Aug 13 06:10:28 yeah. I can do that. Aug 13 06:10:45 my ebay micro HDMI to DVI has arrive. Aug 13 06:10:48 you have Micro HDMI? Aug 13 06:10:52 het me hook it up. Aug 13 06:11:02 lucky! i dont have one!

Aug 13 07:54:56 as in? Aug 13 07:55:02 hoagieman, what is there to be compatible with? it works Aug 13 07:55:13 its all asm in the end Aug 13 07:55:20 the cpu does not care Aug 13 07:55:24 I thought it was turtles all the way down Aug 13 07:55:52 I'm using a cross compiler Aug 13 07:55:58 so? Aug 13 07:55:59 and gcc v 4.6 Aug 13 07:56:03 old Aug 13 07:56:11 no c++11 Aug 13 07:56:24 I dont think it supports things such as std::this_thread Aug 13 07:56:36 do you recommend a cross compiler? Aug 13 07:56:41 what has this got to do with the BBB? Aug 13 07:56:43 that supports c+11 Aug 13 07:56:53 im trying to detach from boost lib Aug 13 07:56:59 gcc.gnu.org Aug 13 07:57:21 there's a toolchain for angstrom Aug 13 07:57:27 there are linaro toolchains too Aug 13 07:57:30 take your pick Aug 13 07:57:42 I am using the linaro tool chain Aug 13 07:57:49 i am pretty sure c+11 is not supported Aug 13 07:57:57 i might be totatlly wrong.. :/ Aug 13 07:57:58 pure kids today cannt find out whats supported and what not Aug 13 07:58:14 apologies!! Aug 13 07:58:22 thats why im here to ask peeople who know! Aug 13 07:58:30 read the changelog of gcc Aug 13 07:58:39 your question is just generic arm toolchain Aug 13 07:58:48 anyone would work Aug 13 07:58:50 as real engineers do Aug 13 07:59:01 there's nothing special about BBB Aug 13 07:59:30 hmm. Aug 13 08:00:44 so.. using the linaro tool chain Aug 13 08:00:58 what os will you use on bbb? Aug 13 08:01:03 things such as std::this_thread will compile without error? Aug 13 08:01:16 ubuntu Aug 13 08:01:16 depends on the version Aug 13 08:01:32 armhf Aug 13 08:01:33 http://gcc.gnu.org/ Aug 13 08:01:46 find out which gcc version you need Aug 13 08:01:50 woglinde, thank you Aug 13 08:02:05 I told it you 5 minutes ago Aug 13 08:02:19 yes you did Aug 13 08:02:26 and you did not read Aug 13 08:02:34 and gcc v4.8 will support full c++11 Aug 13 08:02:45 C++11 is bleeding edge Aug 13 08:02:52 ?? Aug 13 08:02:54 panto not my problem Aug 13 08:03:01 4.8.1 required Aug 13 08:03:26 yes Aug 13 08:03:42 and the default g++ with the ubuntu img is not up to 4.8 Aug 13 08:03:56 it's called bleeding edge for a reason Aug 13 08:04:07 so either you grab one of the builds you can find Aug 13 08:04:12 or you build one yourself Aug 13 08:04:13 hoagieman so thats your problem Aug 13 08:04:55 https://launchpad.net/ubuntu/+source/gcc-4.8 Aug 13 08:05:06 gcc-4.8 armhf 4.8.1-8ubuntu1 Aug 13 08:05:13 13.10 ...

Aug 13 09:14:09 I found that they are respectivly SYSBOOT[15:0] inputs lateched on the rising edge of PWRONRST Aug 13 09:20:42 http://beagleboardtoys.info/index.php?title=BeagleBone_LCD4 Aug 13 09:23:42 What shoud I look up on the page? Aug 13 09:23:50 everything Aug 13 09:23:57 the schematic Aug 13 09:26:23 hm I guess 3,3 V is for the ts and 5 for the lcd Aug 13 09:32:08 in the schematics pdf, where is the connection between P1, P2 (P8, P9 on BB) and the Cape? Aug 13 09:34:30 ? Aug 13 09:34:37 it is the cape schematic Aug 13 09:34:46 p1 is on the cape Aug 13 09:34:51 and connectect to p1 on the BBB Aug 13 09:35:28 okay I understand Aug 13 09:35:47 use the search field and the signal names Aug 13 09:36:06 also, the numbers next to signal names tell you on what other page you can find them Aug 13 09:36:19 not that there are many pages here Aug 13 09:36:25 yeah :) Aug 13 09:36:35 what company? Aug 13 09:36:35 On the schematics on page 3 : Aug 13 09:36:38 at U2 Aug 13 09:36:53 there are the LCD_data connected Aug 13 09:37:05 on the left side Aug 13 09:37:20 and on the right side are the blue red green Aug 13 09:37:53 are this connected? Aug 13 09:38:04 depends Aug 13 09:38:20 okay Aug 13 09:38:31 there is U2 Aug 13 09:38:35 which you can look up Aug 13 09:38:38 and see what it does Aug 13 09:39:16 I don't understand Aug 13 09:39:26 how can I look this up? Aug 13 09:39:40 you enter 74AVC32T245 into google Aug 13 09:40:31 Howzit guys. Can anyone tell me how to execute a script on startup? Systemd is giving me "No [Install] section" problems Aug 13 09:41:07 sorry, on Angstrom Aug 13 09:41:32 * KotH nods knowingly Aug 13 09:42:18 cverster: well, lookup systemd's doc Aug 13 09:42:43 i don't think angstrom's version is different from others Aug 13 09:43:13 oh, it's running on the BBB. it's very different from anything anyone has ever seen! Aug 13 09:43:45 BBB seems to bring out the worst in it ;/ Aug 13 09:44:09 nope, BBB seems to bring out the worst of the n00bs Aug 13 09:44:49 people stop thinking about how to partition the problem into smaller, easier solvable bits and instead assume that anything running on the BBB is a BBB problem Aug 13 09:45:11 sure it is Aug 13 09:45:19 overwise it would be xm problem Aug 13 09:45:24 or bb classic Aug 13 09:45:26 or pc Aug 13 09:45:34 so does someone know how to run startup scripts? Aug 13 09:45:35 xm ? Aug 13 09:46:10 navaati bb xm Aug 13 09:46:41 http://beagleboard.org/Products/BeagleBoard-xM Aug 13 09:47:45 oh, yeah Aug 13 09:47:51 forgot about this one Aug 13 09:48:05 I don't get it Aug 13 09:49:11 I have looked up the 74AVC32T245 Aug 13 09:49:18 but I don't understand the manuel Aug 13 09:49:30 an other question Aug 13 09:49:59 what company? Aug 13 09:50:11 sirona Aug 13 09:50:14 where can I find sourcecode to use the display Aug 13 09:50:23 who worked with the BB-BONE-AUDI-01 cape yet ? Aug 13 09:50:39 why is the company important? Aug 13 09:50:40 cverster: your bbb run angstrom, which run systemd, right ? so it's not a bbb nor angstrom problem, it's a systemd problem. Now, systemd is one of the best documented software i've ever seen, so lookup the doc to understand how it works Aug 13 09:50:43 https://github.com/beagleboard/kernel/tree/3.8 Aug 13 09:50:50 Markus__: it is not Aug 13 09:50:53 but I am curious Aug 13 09:51:14 rob_w: it's a cape to drive luxury cars ? Aug 13 09:51:29 also I need a new tooth Aug 13 09:51:42 :) Aug 13 09:51:47 okay Aug 13 09:51:53 av500: make one from a really thick PCB Aug 13 09:52:03 navaati, no its supposed to be AUIO .. like sound ... not the audi cars ;-) Aug 13 09:52:19 does the bbb have 100k pulldown resistors on all the gpios? Aug 13 09:52:36 rob_w: less fun :D Aug 13 09:52:38 there are some internal pullups/downs Aug 13 09:52:41 I think Aug 13 09:52:43 Stoob: I suspect that will be internal Aug 13 09:52:45 also, schematics Aug 13 09:52:50 SpeedEvil: so yes? Aug 13 09:52:55 so maybe Aug 13 09:52:59 lol Aug 13 09:53:45 Stoob: sort if Aug 13 09:53:54 they can likely be disabled Aug 13 09:54:05 av500 so all markus have to do is solder the right pins and write the dt entries? Aug 13 09:54:11 soo back to https://github.com/beagleboard/kernel/tree/3.8 little tip for what I should look? Aug 13 09:54:47 there is the driver for the actual LCD controller inside the am335x Aug 13 09:54:51 do most people here work in the embedded business ? (rather than hobbyist) Aug 13 09:54:58 and the DT file for e.g. the LCD 4 cape Aug 13 09:55:04 navaati: no Aug 13 09:58:00 in which directory? Aug 13 09:58:19 hacks config pathces recipes ? Aug 13 09:58:34 or more down ? Aug 13 09:59:35 Markus__: in drivers Aug 13 10:00:19 ah, sorry, it's actually not a kernel tree... Aug 13 10:00:28 there is no drivers Aug 13 10:00:31 okay Aug 13 10:00:39 to this Aug 13 10:00:50 I'm can't use kernelspace Aug 13 10:00:55 I have to use userspace Aug 13 10:01:25 Markus__: follow the beginning of the readme to get a kernel tree Aug 13 10:02:04 Markus__ o.O Aug 13 10:02:04 Why do i need a kernel? Aug 13 10:02:06 you can bang spi from userspace using the spidev driver Aug 13 10:02:07 I want to use the lcd bis.. Aug 13 10:02:16 lol Aug 13 10:02:44 av500: what's Markus__ problem? Aug 13 10:04:05 I want to connect a touch display to BB using ubuntu 13.04 and I2C or SPI and the lcd_ signals. I should not use gpios Aug 13 10:04:10 koth he took a job is not b Aug 13 10:04:16 able to do Aug 13 10:05:25 okay Aug 13 10:05:26 Markus__: sit down, order a couple of books from amazon, read them, come back when you know the theory behind that stuff Aug 13 10:05:40 Markus__: what do you mean by "connect" ? you want your ubuntu desktop to appear on the lcd ? Aug 13 10:05:58 anywaym got to go, good luck Aug 13 10:05:59 no I want to draw on this Aug 13 10:06:03 as example Aug 13 10:06:15 o.O Aug 13 10:06:18 Markus__: i do not get what's so complicated about what you are doing Aug 13 10:06:33 Markus__: it's standard stuff, many people have done it, there are examples on the net Aug 13 10:06:35 sit down, open amazon, order etch-a-sketch Aug 13 10:06:38 Markus__: do you have driver problem? Aug 13 10:06:38 I do this for the first tie Aug 13 10:06:44 Markus__: electrical problems? Aug 13 10:06:51 you are not doing it, you are asking us to do it Aug 13 10:07:20 you have to build a foundation for this stuff Aug 13 10:07:39 it's like if you want to dive for pirate gold you need to know how to swim first Aug 13 10:07:46 yeah.. Aug 13 10:07:59 vaizki wrong fist you need to learn to row Aug 13 10:08:16 I studie dual and got this project, I didn't chose it really... Aug 13 10:08:21 but I want to get it Aug 13 10:08:23 Markus__: err.. being a n00b doesnt free you from standard problem solving procedures: 1) make the problem reproducible, 2) partition the problem into smaller bits, 3) check each bit whether it's the problem or not, 4) when you have one bit lef, partion that again 5) rinse 6) repeate Aug 13 10:08:25 first you learn to whip. Aug 13 10:08:31 or you become a pirate yourself and steal it from someone who can swim Aug 13 10:08:59 mru like chinese? Aug 13 10:09:06 Markus__: ok so you're asking us to do your homework? :O Aug 13 10:09:07 Yarr. Aug 13 10:09:18 mru: steal is such a bad word, you should use "kang" instead Aug 13 10:09:20 Polly want a hacker Aug 13 10:09:29 Okay, my first problem is I don't know where I can find information about the lcd_data0 lcd_daa1 Aug 13 10:09:44 Markus__: it's in the TRM Aug 13 10:09:45 This was my first problem, I seached and didn't found it Aug 13 10:09:49 Markus__: and the datasheet Aug 13 10:09:52 from the bb? Aug 13 10:09:55 or the arm? Aug 13 10:09:57 no, the cpu Aug 13 10:10:07 afaik av500 told you that already Aug 13 10:10:08 arm is only a core Aug 13 10:10:11 a desgin Aug 13 10:10:20 which you can license Aug 13 10:11:06 * SpeedEvil wonders if there are individual licences. Aug 13 10:11:06 how much is a personal licence to be able to use it in your FPGA. Aug 13 10:11:07 not the cpu, the soc Aug 13 10:11:08 koth hm he is at your number 6) now Aug 13 10:11:14 or relay computer. Aug 13 10:11:22 it seems I looked up the wrong pdf... Aug 13 10:11:22 woglinde: 6) pay someone else to do it? Aug 13 10:11:26 SpeedEvil if you have have the money Aug 13 10:11:30 koth no repeat Aug 13 10:11:34 SpeedEvil: no such thing Aug 13 10:11:44 ah.. Aug 13 10:11:49 * KotH cannot count Aug 13 10:12:12 * SpeedEvil suddenly wants to make a relay arm. Aug 13 10:12:15 anyways, time for a calzone Aug 13 10:12:19 bbl, have fun Aug 13 10:12:26 ciao koth Aug 13 10:12:35 tschüs Aug 13 10:13:52 Markus__: ahjo.. gibt de lüt echli meh möglichkeite dir z'helfe. gib ine meh infos was scho gmacht häsch und was nöd und worum d'glaubsch dass dis problem döt isch wo es isch Aug 13 10:14:16 Markus__: and keep calm and continue debugging Aug 13 10:16:07 he's not debugging, he's spinning his wheels trying to find something to grasp so he can get started? Aug 13 10:16:57 Vaizki right pins for soldering Aug 13 10:17:10 @vaizki: yes exactly, I search for an example Aug 13 10:17:41 ich hab im dt geschaut ob ich an einer stelle wie /sys/class/gpio/ etwas finden kann wo ich die leds ansteuern kann, hab das Problem gegooglet in goglegroups gesucht und geschaut, dort selber nachgefragt, manuels gelesen Aug 13 10:18:02 well find the datasheet for your lcd display. then read the TRM (http://www.ti.com/lit/ug/spruh73h/spruh73h.pdf) from page 1098 onwards. Aug 13 10:18:15 can't really help you more than that without actually doing the work for you Aug 13 10:18:55 hmm Aug 13 10:19:42 can you post a link to an example where I can see how I "connect" / use an touchdisplay directly with the BB? Aug 13 10:19:51 no Aug 13 10:20:41 why? Aug 13 10:20:49 :O Aug 13 10:20:55 I don't want to copy Aug 13 10:21:01 why would I google that for you? Aug 13 10:21:12 okay Aug 13 10:21:13 I have never done anything with parallel LCDs Aug 13 10:21:22 then please tell me for what I should seach Aug 13 10:21:28 there is no shortcut Aug 13 10:21:30 okay Aug 13 10:21:32 sorry Aug 13 10:21:45 okay Aug 13 10:22:21 do you know how if I can manuel write the lcd_data? Aug 13 10:22:33 realistically your best bet is to find a ready made framebuffer driver for the am335x lcd driver which happens to support your display Aug 13 10:23:02 if that doesn't happen, no I don't know how to manually write to those pins Aug 13 10:23:12 it would take me a day proabably to find out ;) Aug 13 10:23:22 that is good :) Aug 13 10:23:39 I thought I was my faught not to get it fast Aug 13 10:24:07 okay, I will look know up the referencemanuel Aug 13 10:24:36 and then google again ( :( I hate to google so long ) Aug 13 10:24:50 thank you and the others for the thoughts and the help! Aug 13 10:36:15 hm split? Aug 13 10:38:55 http://youtu.be/gb_qHP7VaZE?t=1m15s Aug 13 10:49:13 something for jkridner: http://www.heise.de/newsticker/meldung/JavaScript-fuer-Mikrocontroller-1934018.html Aug 13 10:53:48 mru yes Aug 13 10:54:41 "This version is completely free. However if you wish to save the programs you have written to Flash..." Aug 13 10:55:08 you need to use a hex editor to flip a branch Aug 13 10:57:33 "simple code written in Espruino can actually be more power efficient than that written in C!" Aug 13 10:57:52 I think, that is just enough for today :p Aug 13 10:58:07 *g* Aug 13 10:58:12 jit it Aug 13 10:58:27 on an m3... sure Aug 13 10:58:50 chocolate Aug 13 10:59:23 I might accept that in some cases $dodgy_language may be _good enough_ Aug 13 10:59:55 but adding a layer on top of C is not going to be faster than C Aug 13 11:01:27 €4 Aug 13 11:01:32 price is fair Aug 13 11:01:55 wut? Aug 13 11:02:59 zut Aug 13 11:12:54 oh, there he is Aug 13 11:27:59 dahm, i thought this channel did support the matrix. . . Aug 13 11:28:44 hm? Aug 13 11:29:17 [00:00] for the matrix ask Neo Aug 13 11:30:10 i was just being silly which isnt unusual for me, especialy after having just woken up Aug 13 11:33:47 ah, I missed that line Aug 13 11:38:55 could it be that i2c busses get numbered in the order they are registered rather then their specific bus id name Aug 13 11:55:51 rob_w: yes Aug 13 11:55:53 I think so Aug 13 11:56:00 yes indeed Aug 13 11:56:53 i was confused about the sys/bus/i2c/devices/ numbering .. as its the occurance of the busses instead of their names Aug 13 12:09:27 hi Aug 13 12:57:56 Russ: http://oggcamp.org/ Aug 13 12:58:11 Some fun tips in there : http://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html Aug 13 13:00:23 prpplague: I went to OggCamp a year or two ago, it was good fun Aug 13 13:04:38 welp, wifi working on BBB now using the Edimax EW-7811Un Aug 13 13:05:59 spirilis is this some news? Aug 13 13:06:07 no Aug 13 13:06:17 just mindlessly announcing that I got one and it shows up :) Aug 13 13:20:09 das: don't _ever_ use gcc extensions Aug 13 13:20:28 most of them are horrific and completely unnecessary Aug 13 13:21:33 there are some sexy ones, but I'll take your word for it Aug 13 13:21:57 yes, a few of them have uses Aug 13 13:22:07 any body going to that oggcamp thing? Aug 13 13:22:10 but even those should be used sparingly and always with a fallback Aug 13 13:22:44 keesj: since the only explanation of what it is is apparently in a video (wtf), I suppose I'm not Aug 13 13:24:02 * keesj listens to the "Linux Outlaws" podcast so I do have some idea Aug 13 13:24:13 atomic functions Aug 13 13:24:21 woglinde: aren't those in c11? Aug 13 13:24:45 but yes, those fall in the useful category Aug 13 13:24:52 most of them are just ridiculous Aug 13 13:25:43 because you are not programming for more threads? Aug 13 13:25:55 the atomics are fine Aug 13 13:26:02 most of the _other_ extensions are insane Aug 13 13:26:05 _most_ Aug 13 13:26:09 ah okay Aug 13 13:26:21 a few of the __builtin_foo are useful as well Aug 13 13:26:43 but only when you know they compile to something sane on your target machine Aug 13 13:50:36 keesj: I would do, but I don't think I can commit to Liverpool for a few days Aug 13 13:51:10 keesj: with food + beer + travel + accom, you're probably talking over £200 Aug 13 13:51:47 if it was closer.... last time I went I managed to stay with a friend, which brought it into a reasonable price bracket Aug 13 14:04:38 av500: yeah after inning #7 i get bored of football as well Aug 13 14:05:45 I do like it when the ptcher and the goalie get into fights and beat each other with their racquets. Aug 13 14:06:26 It usually means the centers and the defensive linemen have to deal without them to take the puck across the yardlines. Aug 13 14:06:55 In case everyone missed when I posted before, my employer did an independent temperature test of the Beagle Bone Black. NEMA temperature(-35C to 75C) : "BBB was able to acquire IP address and run basic test of Blink LEDs." Aug 13 14:07:30 (They mostly were concerned that the Ethernet port wouldn't work based on parts list ratings) Aug 13 14:08:00 That was the 2nd round of this test they did. Aug 13 14:08:34 agmlego: you clearly know more about sports than you let on Aug 13 14:08:44 you couldn't have made that many errors otherwise Aug 13 14:08:52 agmlego: not to mention the catcher and batter have to line dance on that line Aug 13 14:09:44 mranostay: Just until the infielder passes the puck to the shortstop to score a basket. Aug 13 14:10:06 mranostay: Who, me? I am a 100%, born-and-raised, hardcore sportsball fan. Aug 13 14:10:11 * mru throws some cricket terms at agmlego and mranostay Aug 13 14:10:31 * agmlego tosses a snake at mru's crickets. Aug 13 14:10:31 SoCo: interesting test. what's the application? Aug 13 14:11:09 SoCo_cpp_: be aware that _one_ board working outside rated temperatures doesn't mean others will Aug 13 14:11:21 agmlego: this fake game sounds about 1000x times more interesting than baeball Aug 13 14:11:21 nor that it will work for any extended period of time Aug 13 14:11:27 *baseball Aug 13 14:11:41 mranostay: Watching paint dry is 1000x more exciting than baseball. Aug 13 14:11:43 baseball is horrible Aug 13 14:12:02 but we all know it's not about the game Aug 13 14:12:31 it's about eating hotdogs and drinking crap beer Aug 13 14:12:33 its about the girls in bikinis Aug 13 14:12:39 oh wait Aug 13 14:12:54 they have women's baseball? Aug 13 14:12:55 mru: i can do that at home Aug 13 14:13:06 mru: That is true. We will likely do more in the future. Aug 13 14:13:07 mranostay: of course you can Aug 13 14:13:24 and not spend $10 for a bud light Aug 13 14:13:40 I'm merely relating what myself and a few (british) workmates observed on a 'safari' trip to the stadium Aug 13 14:14:29 I thought it was mostly about the traffic jam to and from the stadium? Aug 13 14:14:36 since you spend most time there Aug 13 14:14:59 (hopefully you packed cheap beer) Aug 13 14:15:01 no you leave in the 8th ining to bet it Aug 13 14:15:18 av500: good luck with that. they search bags Aug 13 14:15:26 don't they usually stop serving beer in the 6th inning or something lame? Aug 13 14:15:39 mranostay: they search beer bellies too? Aug 13 14:16:01 i don't know never been to a baseball game after i reached the drinking age Aug 13 14:17:40 das_plague: btw i figured you as a footbal fan Aug 13 14:17:55 mranostay: uh why? Aug 13 14:18:09 you live in texas Aug 13 14:18:16 My dad was a purchasing agent for a factory when I was growing up. We got free tickets to St. Louis Cardinal games all the time. Aug 13 14:18:25 I was surprised to learn das_plague did not know about football Aug 13 14:18:43 I thought you couldn't get a passport witout knowing about football Aug 13 14:18:57 mranostay: http://youtu.be/E0JNH-0xg8w Aug 13 14:19:12 mranostay: and spent pretty much all of my adult life in the west indies Aug 13 14:19:41 Crofton|work: hehe Aug 13 14:20:07 yea, not sure why people would be surprised, it's not like everyone watches/plays the sport Aug 13 14:20:37 das_plague: most americans find that unfathomable Aug 13 14:21:16 mru: seems so Aug 13 14:21:35 * das_plague heads to the office , bbiab Aug 13 14:21:35 I thought one half watches baseball, no? Aug 13 14:21:49 * das_plague would not know Aug 13 14:22:00 none of my local friends watch any sporting events Aug 13 14:23:34 do any of your virtual or imaginar friends? Aug 13 14:23:52 my paid friends do what I tell them too Aug 13 14:24:01 to Aug 13 14:24:24 KotH: no clue, it has never been a topic of conversation until now Aug 13 14:26:31 so you admit to having imaginary friends Aug 13 14:27:03 my whole world is imaginary Aug 13 14:27:12 oh, you're a solipsist Aug 13 14:27:17 * das_plague is really gone now after making a cup of coffee Aug 13 14:27:26 coffinist Aug 13 14:28:02 * KotH goes as well Aug 13 14:29:56 http://infohost.nmt.edu/~shipman/reading/solipsist.html Aug 13 14:31:40 [kernel] koenkooi pushed 2 new commits to 3.8: http://git.io/UO_mqQ Aug 13 14:31:40 kernel/3.8 76361d4 Koen Kooi: 3.8: convert SPI capes to SPIdev...

Aug 13 15:10:09 micges: if 10.1" is also okay, then have a look: http://www.adafruit.com/products/1287 Aug 13 15:12:33 philenotfound: thanks Aug 13 15:17:54 http://www.chalk-elec.com/ Aug 13 15:17:57 has 10.1 too Aug 13 16:04:44 * mranostay emeb shakes in Aug 13 16:09:04 * emeb shakes cane Aug 13 16:28:18 Hi everyone! Aug 13 16:29:56 I came here to ask you if the beaglebone black can handle doing a little storage / backup server ? Aug 13 16:30:03 bridging 5/9ths Aug 13 16:31:51 the only interface for mass storage is usb Aug 13 16:31:58 that's not a good start Aug 13 16:32:35 I'll use a 3TB external hard drive connected to the usb host Aug 13 16:33:00 and you're happy with that? Aug 13 16:33:21 you think the speed of the usb hub won't be enough ? Aug 13 16:33:54 I think usb for mass storage is generally a bad idea Aug 13 16:34:15 Okay Aug 13 16:34:42 for a storage server, I'd also want to have some kind of raid Aug 13 16:34:54 What can you advise me ? Another board or an other way than usb ? Aug 13 16:35:00 * ogra_ thinks with 3.0 USB storage got bearable Aug 13 16:35:01 and that adds extra load on the interface Aug 13 16:35:11 ogra_: maybe, but the beagles don't have that Aug 13 16:35:16 yeah Aug 13 16:35:21 usb3 isn't really usb as we know it Aug 13 16:35:42 it's about as similar to usb as pcie is to pci Aug 13 16:35:57 * mranostay calls KotH Aug 13 16:36:11 mranostay: what are you calling KotH? Aug 13 16:36:27 <_Odin_> what kind of power cord do you need for the beagle bone black? Aug 13 16:37:15 names Aug 13 16:37:17 * ogra_ recommends copper ... Aug 13 16:37:24 with insulation ... Aug 13 16:37:25 i don't kiss and tell Aug 13 16:37:47 ogra_: not silver? Aug 13 16:38:04 So what would you do in my place for building a storage server ? Aug 13 16:38:16 mru, only for tweeters :) Aug 13 16:38:31 Celrenheit: I'd use something with sata and GbE Aug 13 16:38:37 <_Odin_> u wot mate Aug 13 16:38:39 mranostay: you have summoned me, mere mortal! Aug 13 16:38:51 Celrenheit, Get a small Atom board with enough SATA ports Aug 13 16:39:27 the cpu is irrelevant Aug 13 16:39:34 as long as it has sata and gbe Aug 13 16:39:50 mru, not that irrelevant Aug 13 16:39:56 you need to pump the data in/out Aug 13 16:40:06 the cpu architecture is irrelevant Aug 13 16:40:11 ah, yes Aug 13 16:40:15 there are x86, arm, mips, powerpc etc that can do it Aug 13 16:40:23 Okay thanks Aug 13 16:40:47 Point is, there are small Atom boards available with many SATA ports. So you might actually find what you are looking for Aug 13 16:41:07 dnil: you can always use the bbb Aug 13 16:41:18 it'll perform badly, but you have a lot of hack value Aug 13 16:41:25 KotH, for what? Aug 13 16:41:28 and you can feel great for having done embedded linux Aug 13 16:41:28 hey guys.. i installed the latest Angstrom image.. i can ssh into the 7.2 ip but not into the ethernet? Aug 13 16:41:29 KotH: your bbb has sata and gbe? Aug 13 16:41:41 mru: yeah! i bitbang it! Aug 13 16:42:07 KotH: don't get me worked up this early in the morning Aug 13 16:42:23 hahaha nevermind? i was connecting to the wrong IP Aug 13 16:42:52 mranostay: relax and take a beer Aug 13 16:43:03 10a Aug 13 16:43:09 http://26-26-54.hardwarebug.org/171 Aug 13 16:43:18 * mranostay knew that was coming Aug 13 16:43:59 Okay i'll see but it's not for high frequency storing it's just for like 3-4 people not at the same and just for backing up projects Aug 13 16:45:26 so i'll see because whatever happens even if it is not performant i'll reuse it anyway as a little node.js webserver Aug 13 16:45:52 Thanks for the informations and the Atom board ;) Aug 13 16:45:56 Celrenheit, of course you can use the BBB for this. But if you ask for a storage recommendation you will get pointers to "good" solutions. And they all involve redundancy Aug 13 16:48:03 or you will be mocked for asking such a question in #beagle Aug 13 16:48:13 dnil: Yep, i thought you'll have "good" solutions, that's why i came here to ask you guys Aug 13 17:01:47 One last question (maybe stupid), is there a way to add a usb 3.0 host on the bbb ? Aug 13 17:02:12 no it doesn't have usb3 Aug 13 17:02:27 but usb3 peripherals should be backwards compatible Aug 13 17:05:29 Yep they are but is there a way to add this functionnality by replacing the usb 2.0 by usb 3.0 or using the I/O pins ? Aug 13 17:06:12 can you turn a gasoline engine into a jet engine? Aug 13 17:08:20 hahaha Aug 13 17:08:53 That's the kind of answer i was expecting by asking a stupid question ^^ Aug 13 17:11:02 dm8tbr: Basically not. Aug 13 17:20:41 SpeedEvil: but you could attach it to one! (same as you could attach the bbb to something else that speaks usb3 and has the power consumption of 100BBBs Aug 13 17:21:14 there were early attempts to do asically this - in the 40s. Aug 13 17:21:15 They did not work Aug 13 17:21:24 dm8tbr: drive a car onto a hercules? Aug 13 17:22:09 mru: yeah, that sort of thing Aug 13 17:22:31 why would you want to hurt a hercules? Aug 13 17:22:40 hi ka6sox Aug 13 17:22:46 ok, that's a propeller plane, but still Aug 13 17:22:53 * dm8tbr was going to say Aug 13 17:22:58 its a wonderful airplane... Aug 13 17:23:22 morning woglinde Aug 13 17:24:44 ka6sox: happy moose morning to you Aug 13 17:26:11 my moose days are over (till next spring) Aug 13 17:33:32 moose days of spring Aug 13 17:33:53 ka6sox: isn't that breeding season? Aug 13 17:34:46 ssssh...you will wake up the moose Aug 13 17:35:02 ka6sox, that's canada? Aug 13 17:35:33 wmat: have moose stories for the room? Aug 13 17:42:34 panto, we have em up in Alyeska too. Aug 13 18:02:51 * mranostay heads to get some mooseburgers Aug 13 18:04:57 gogo Aug 13 18:05:26 gogo gageto mooose Aug 13 18:25:54 hello Aug 13 18:26:29 anybody out there could suggest me a good guide for setting up simulink for code generation? Aug 13 18:26:51 by using embeeded coder and eclipse as IDE Aug 13 18:27:12 ? Aug 13 18:27:27 wrong channel? Aug 13 18:28:44 woglinde, usually this is for a class and they don't bother to look up things before asking :) (but not always) Aug 13 18:31:33 setting up simulink for code generation? Aug 13 18:31:48 isnt that like "have the right package installed and press a button"? Aug 13 18:32:11 koth yes its coding for you Aug 13 18:32:13 emebdded Aug 13 18:32:34 beside, if your state machine is so complex that you cannot code it from hand anymore, you are doing it wrong ^^' Aug 13 18:33:11 woglinde: i've heard of people who use matlab/simulink to generate vhdl code directly Aug 13 18:33:30 i really dont want to know how the synthesized stuff locks like ^^;' Aug 13 18:33:52 yes, that is true Aug 13 18:34:17 KotH : see fpgautils Aug 13 18:35:01 hmm? what's that? and what about it? Aug 13 18:36:00 you can build bitstreams with C code Aug 13 18:36:22 see also fpgasm Aug 13 18:36:33 that ought to be efficient as hell... Aug 13 18:36:37 unrelated, but also interesting. Aug 13 18:36:50 ah.. it's a verilog synthesizer Aug 13 18:36:52 ka6sox : optimization is a different problem, fpgautils is a start. Aug 13 18:36:57 KotH : no, it is not. Aug 13 18:37:04 20:36 < CareBear\> you can build bitstreams with C code Aug 13 18:37:05 CareBear\, understood... Aug 13 18:37:12 that sounds very much like verliog Aug 13 18:37:15 check it out instead of being a smartass Aug 13 18:37:18 I'm off for dinner Aug 13 18:37:30 * KotH is not a smart ass, my ass is not smart at all Aug 13 18:37:41 fpagutils...looking Aug 13 18:38:09 sorry, fpgatools Aug 13 18:38:19 https://github.com/Wolfgang-Spraul/fpgatools Aug 13 18:38:41 CareBear\, okay...that makes more sense..thanks! Aug 13 18:39:02 hm I was using mitrion-c which made vhdl code too Aug 13 18:40:38 there are literally hundreds of attempts to use general purpose programming languages to describe hardware Aug 13 18:41:02 most of them fail because people do not understand that sequential languages are inherently bad at describing parallel processes Aug 13 18:41:30 and very few people realize that those few hw description languages that are successfull are dataflow languages Aug 13 18:41:30 koth look a mitrion-c Aug 13 18:41:45 which uses data-flow modell Aug 13 18:42:18 then they understood something ;) Aug 13 18:44:41 hmm.. i dont seem to be able to find a description of the language Aug 13 18:46:05 * agmlego did hardware description in LabVIEW for a while. Aug 13 18:46:24 labview isnt bad for hw description Aug 13 18:46:32 though schematic entry doesnt scale far Aug 13 18:46:40 Yeah. Aug 13 18:46:56 koth http://download.mitrionics.com/mitrion-sdk-pe/ Aug 13 18:47:04 Still, something graphical is almost necessarily better for the parallelism thing than a textual language. Aug 13 18:47:11 At least for beginners. Aug 13 18:47:18 agmlego: nack Aug 13 18:47:52 agmlego: forgo something convoluted like verilog and see the light of vhdl, and you will be instantly able to write nice and clean hardware ;) Aug 13 18:48:12 I did some vhdl. Aug 13 18:48:16 It was OK. Aug 13 18:48:26 woglinde: i dont want to download the whole sdk just to see a couple of examples ^^' Aug 13 18:48:29 Showing kids how to do multiprocessing? LabVIEW, all the way. Aug 13 18:48:39 vhdl's biggest drawback is that it's overly verbose Aug 13 18:48:41 koth life is hard Aug 13 18:48:44 other than that, it's a nice language Aug 13 18:49:13 woglinde: yeah.. s'läbe isch wiä e hüenerleitere: churz und verschisse Aug 13 18:50:03 * KotH mumbles a couple other dark incantations under his breath and summons the dark troll Aug 13 18:51:05 yes? Aug 13 18:52:26 be gone! petty daemon! you are not the dark troll! Aug 13 18:53:30 KotH: going to ELCE? Aug 13 18:54:02 looks like it Aug 13 19:00:12 <_troll_> KotH: you summoned Aug 13 19:11:34 ah it apeared! Aug 13 19:11:39 long live the dark troll! Aug 13 19:12:11 to you we pledge our trollishnes! Aug 13 19:12:24 g'night Aug 13 19:15:39 KotH: hey, even the troll goes for dinner once in a while Aug 13 19:16:45 hola everyone Aug 13 19:17:25 mru: es sei euch gewährt, oh herr! Aug 13 19:26:04 i've built a image for my beagleboard. the IMAGES_FSTYPE.. setting creates rootfs.tar.bz2/xz by default, what's the difference to a img.xz? Aug 13 19:26:26 we need more users http://i.imgur.com/znsbZzB.jpg Aug 13 19:26:42 freinhard diffrent compression Aug 13 19:26:50 the docs don't list a img. type http://docs.openembedded.org/usermanual/html/image_types.html Aug 13 19:27:52 woglinde: when i read rootfs.tar.bz2, this is a tar archive containing just the files compressed by bz2, easy to understand Aug 13 19:28:02 woglinde: img.xz can be anything compressed with xz Aug 13 19:28:31 oh okay Aug 13 19:28:53 maybee a complete image which you can decompress and dd to disk or partition Aug 13 19:29:37 yes, probably a filesystem image Aug 13 19:31:05 ok, since all howtos for updating the beagleboard refer to img.xz files, how do i convince bitbake to create them? Aug 13 19:32:01 das: just 600? Aug 13 19:32:26 das: i'm quite sure any kid of the 80s had a couple hundred of those Aug 13 19:32:33 das: any addict... thousands Aug 13 19:32:56 KotH: need to recruit about 500 noobs, teach them embedded stuff, then make them bitter and voila ! Aug 13 19:33:13 heh Aug 13 19:33:17 bitternes comes trough life, no matter whether we teach them or not Aug 13 19:33:29 life is bitternes, bitternes is life Aug 13 19:33:50 I like circular logic because it's circular Aug 13 19:33:54 everyone praise the allmighty DeliciousChocolateTroll! Aug 13 19:33:55 unless you have chocolate. Aug 13 19:35:06 chocolate? Aug 13 19:35:07 KotH cant forget beer though. beer doesnt make trolls, it just makes trolls unconcience Aug 13 19:35:08 where Aug 13 19:35:17 I have the other important ingredient. Aug 13 19:35:21 *coffee* Aug 13 19:35:25 it is 7:30am Aug 13 19:35:29 *coffee* is importnat Aug 13 19:35:31 wired trolls . . . Aug 13 19:35:42 * mrpackethead is not a troll Aug 13 19:35:46 * mrpackethead is a hobbit Aug 13 19:35:50 lol Aug 13 19:35:54 how many times do i have to tell you Aug 13 19:36:29 i love my customers Aug 13 19:36:33 i love my customers Aug 13 19:36:36 i love my customers Aug 13 19:36:47 I'm jsut saying it Aug 13 19:36:48 Goebels much ? Aug 13 19:36:48 today is payday ? Aug 13 19:36:53 so i don't kill them. Aug 13 19:37:33 mrpackethead let your customer pay for there stupiness Aug 13 19:37:34 iraqi propaganda minister Aug 13 19:39:15 m_billybob: it's payday 2 actually Aug 13 19:46:25 If i build an MLO and u-boot.img and put them on a preformatted sdcard, should they be picked up and used by the BBB? Aug 13 19:47:04 I'm not sure why but it seems to be picking up the uEnv.txt from the sdcard but sourcing the images from the eMMC? Aug 13 19:52:28 hey guys? i have a MicroSD ( non image, just storage ) but it can't seem to boot up with the SD card plugged in... Aug 13 19:53:16 brimestone: Yup. The bone defaults to trying to boot from uSD. If there is nothing there to boot, it hangs. Aug 13 19:53:34 I think there are u-boot options to fix this, but I do not know them. Aug 13 19:53:39 how can i tell it to boot from the eMMC? Aug 13 19:53:50 ohh really? Aug 13 19:54:05 what is the u-boot anyway Aug 13 19:54:17 u-boot is the system bootloader. Aug 13 19:54:19 i've seen several pple mention u-boot Aug 13 19:54:23 Like grub for desktop machines. Aug 13 19:54:26 ohhh.. Aug 13 19:54:44 It is what the machine runs to find the operating system to boot. Aug 13 19:54:57 yeah.. im familiar with the grub Aug 13 19:55:33 I just read that the MLO has to be copied to the sd card first - is that true as it sounds like BS Aug 13 19:57:31 one way to think of u-boot, is to think of it for the BBB as a PCs BIOS is to the PC Aug 13 19:57:44 ( sort of ) Aug 13 19:57:51 i was just reading the Documentation of u-boot Aug 13 19:58:13 looks very "I don't want to get into" Aug 13 19:58:40 its not all that hard just takes time to learn what you need Aug 13 19:58:42 Probably. Aug 13 19:59:58 imagine this. you have 500 boards you need to "flash" a linux image and rootfs to . . . you could technically do that through uboot. booting an mini OS over a network, and atumatically flash the needed files and file system to each and every BBB Aug 13 20:00:04 or any device for that matter Aug 13 20:00:19 automatically even Aug 13 20:00:22 yup.. like a netboot Aug 13 20:00:48 i do it all the time, when i roll out version update for my clients Aug 13 20:01:20 well in order to load the kernel over TFTP, you should be familiar with at least a small portion of u-boot Aug 13 20:02:14 it took me a week tinkering with u-boot ( uEnv.txt really ) to figure that out on my own Aug 13 20:02:31 and i still had to ask some questions Aug 13 20:03:22 i know.. the Manuals table of contents alone is crasy Aug 13 20:03:38 which manual is that ? Aug 13 20:04:11 well its not for BBB but its generic u-boot Aug 13 20:04:12 http://www.denx.de/wiki/DULG/Manual Aug 13 20:04:19 only one i found was by digikey or some such and it has some specifics to their version of u-boot Aug 13 20:04:20 anyone notice the conference hotel is effing expensive? Aug 13 20:04:47 * mranostay hates to know what non conference rate would be Aug 13 20:05:06 brimestone ah yeah i didnt read that one i prefer PDF Aug 13 20:05:33 hahaha Aug 13 20:06:12 Is it common that dmesg gives me over and over again RNDIS_OID_GEN_RCV_NO_BUFFER on the BBB under Angstrom? Aug 13 20:06:33 so bare Angstrom already took 1.1GB which leaves 595MB of space.. Aug 13 20:06:41 how do you guys deal with this? Aug 13 20:07:08 I run Arch Aug 13 20:07:14 Angstrom is 1GB now ? oO Aug 13 20:07:18 and I run debian Aug 13 20:07:24 i mean yes, this is a luxury compared to PI or Arduino?. but hehehe Aug 13 20:07:31 das its over 1.4GB on mine Aug 13 20:07:37 Angstrom is 1.1GB Yes... Aug 13 20:07:37 stock Aug 13 20:07:44 brimestone: there are 2 Ã¥ngström images, one is just the base system, the other has all the cloud9 etc n00b dev stuff Aug 13 20:08:06 really? Aug 13 20:08:09 oy pretty bloated since I last used it Aug 13 20:08:18 Vaizki actually i think there are 3, maybe even 4. well perhaps not stock downloadable ready to use Aug 13 20:08:42 i know here are 3-4 *buildable* through Yocto Aug 13 20:08:49 well not sure how many because I don't use it. Aug 13 20:08:55 me either Aug 13 20:08:57 actually i download the eMMC flasher.. as of July 30 2013 Aug 13 20:09:02 Is the ability to use the notation bootm ${kloadaddr} - ${fdtaddr} a TI tree extension of u-boot as its not working on a clean checkout of u-boot master Aug 13 20:09:04 but i spent a week trying to figure out how to build my own Aug 13 20:09:31 exosyst: bootm is not in "mainline" u-boot? Aug 13 20:09:37 it is Aug 13 20:09:41 the hyphenation Aug 13 20:10:04 I spent at least a week too in building an own one. Now I am using a larger SD :D Aug 13 20:10:17 If i use bootm ${kloadaddr} - ${fdtaddr}, it prints out the usage for bootm Aug 13 20:10:18 so, i should compile my executables on a separate machine? or dump into a USB dongle (Flash drive) configure and compile.. then install Aug 13 20:10:47 exosyst which type of kernel image are you trying ot use with it Aug 13 20:11:00 xImage ? uImage ? Aug 13 20:11:05 err zImage* Aug 13 20:11:28 the hyphen means there is no initrd? Aug 13 20:11:30 [ 761.278705] gadget: rndis req21.00 v0000 i0000 l36 [ 761.278832] gen_ndis_query_resp: RNDIS_OID_GEN_RCV_NO_BUFFER This message is comming over and over again in my dmesg. Do I have to worry about it? Aug 13 20:11:32 uImage Aug 13 20:11:54 hmmm - it looks like kloadaddr isn't defined in mainline u-boot Aug 13 20:12:35 nauserr do you have an optargs=... in your uEnv.txt file ? Aug 13 20:12:38 exosyst Aug 13 20:12:39 uenvcmd=setenv autoload no; run loadtftp; run netargs; bootm 0x80200000 - 0x815f0000 Aug 13 20:12:57 and I think you could use uboot without linux kernel to reflash devices Aug 13 20:13:17 thats for netboot but thats how i use bootm if that helps Aug 13 20:13:46 m_billybob, it was the kloadaddr Aug 13 20:13:59 not defined? Aug 13 20:14:00 that seems to be a TIism, it's just loadaddr in mainline Aug 13 20:14:13 ah right, thats why i "hard code" the kernel / DT address Aug 13 20:14:13 it's just a variable.. Aug 13 20:14:47 load adresses, whichever you prefer Aug 13 20:15:04 i think mainline uses $loadaddress but im not 100% positive Aug 13 20:15:10 * m_billybob looks Aug 13 20:15:16 m_billybob, it's just loadaddr Aug 13 20:15:51 ah.. canada just woke up Aug 13 20:16:17 this helps me to remember -> http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/am335x_evm.h;hb=HEAD#l57 Aug 13 20:16:22 may or may not be os use to you Aug 13 20:16:24 but aren't those loadaddr and kloadaddr just variables? it's not a code change, just what the default uboot environment is before reading uEnv.txt Aug 13 20:16:33 KotH: howdy friend Aug 13 20:17:24 das: hau di selber! ;) Aug 13 20:17:29 Vaizki, they are just variables, loadaddr *was* always the location to load the kernel in other SoCs i've worked with, it's instead kloadaddr on the BBB which made me think there was an update of some sort and Aug 13 20:18:08 Vaizki, when using env variables in uboot though, it helps if the variabels you use are already used by uboot. this way you dont have to define your own variables and write tons of text to support those variables Aug 13 20:18:09 btw is there a way to see the default environment from a uboot.img? Aug 13 20:18:31 hmmh? you can't just go an assign a random variable name stuff? Aug 13 20:18:34 I thought you can Aug 13 20:18:36 you can Aug 13 20:18:38 like shell variable Aug 13 20:18:47 but look at that link i just pasted Aug 13 20:19:09 there are already many variables coded into uboot by default Aug 13 20:19:13 yes Aug 13 20:19:25 Vaizki, you can run strings against uboot.img to get a hold of most of the settings Aug 13 20:20:07 so if you just set one of those variable you dont have to write in a bunch of "support" override text into your uEnv.txt file to make sure it gets used properly Aug 13 20:20:39 you just set one or many of those existing variables and they get used properly Aug 13 20:20:39 exosyst: sure, just wondering if there is a clean way :) Aug 13 20:21:23 Oddly there's a patch called 0005-beaglebone-use-kloadaddr-to-avoid-copying-the-kernel but it doesn't seem to avoid copying the kernel from my understanding Aug 13 20:21:39 Thats what inserts this kloadaddr variable Aug 13 20:21:41 m_billybob: yea I get that no prob. Aug 13 20:22:01 what is the purpose of kloadaddr anyhow ? ive seen it before but ive neve rused it Aug 13 20:22:05 avoid copying the kernel? what? Aug 13 20:22:30 kloadaddr is just a hex number to indicate where kernel image should be loaded? Aug 13 20:22:45 well not hex number but 64bit address Aug 13 20:22:59 m_billybob, Vaizki http://www.crashcourse.ca/wiki/index.php/U-Boot_on_the_BBB#0005-beaglebone-use-kloadaddr-to-avoid-copying-the-kernel.patch Aug 13 20:23:01 well thats what loadaddr does im assumning kloadaddr is some slight variation of the same Aug 13 20:23:22 it's just a different naming Aug 13 20:23:44 i look at it from the bootm / bootz perspective Aug 13 20:23:49 it's like using "j" instead of "i" for loop variable name ;) Aug 13 20:23:53 they do the same thing but with different kernel image types Aug 13 20:25:00 exosyst: ok I don't get it either.. unless uboot normally relocates the kernel to 0x80007fc0 unless you happened to put it there Aug 13 20:25:20 hey guys? how do i get net-snmp into BBB? Aug 13 20:26:05 http://processors.wiki.ti.com/index.php/All_This_For_1_Second_Boot#Kernel_Relocation Aug 13 20:26:08 ta-daa Aug 13 20:26:16 u-boot relocates Kernel to 0x80008000 using memmove function. This step happens after crc32 check passes. Relocation can be avoided by making the first copy smartly. uImage (Kernel image with header) has 0x40 byte header. Copy to 0x80007FC0 puts actual Kernel at 0x80008000 Aug 13 20:26:48 hey. Aug 13 20:27:23 my cloud9 is bugged. I only have Preferences on the left side and none of the drop down menus work. anyone seen this? Aug 13 20:27:46 1 second boot into what ? Aug 13 20:27:56 getty? Aug 13 20:28:46 Vaizki, nice spot. How crazy though lol Aug 13 20:29:36 hmmm going ot take ~20 to load/setup a rootfs anyhow Aug 13 20:29:42 well over NFS anyhow Aug 13 20:29:49 20 seconds that is Aug 13 20:29:59 how can I reinstall just cloud 9? Aug 13 20:30:16 goge, no idea Aug 13 20:30:28 * m_billybob doesnt use any of that Aug 13 20:30:58 goge you can try asking on the beagleboard google groups Aug 13 20:31:00 what's your dev environment? I'm open to suggestions Aug 13 20:31:32 dev enviornment is actually on an X86 system have two one on windows 7 the other on debian x86 Aug 13 20:32:09 i use the debian system for rebuilding the kernel etc, and windows to write userland apps Aug 13 20:33:03 what IDE? Aug 13 20:33:17 vim Aug 13 20:33:18 code::blocks on windows, cmd line on debian Aug 13 20:34:09 for text editing i mostly use sublime text though i like dark themes . .. Aug 13 20:34:36 that is i write the majority of my code in a texteditor ( sublime text ) Aug 13 20:34:55 I tried that sublime text once but it's buggy syntaxically speaking Aug 13 20:35:08 i dont use a lot of plugins Aug 13 20:35:17 someone (me?) should tweak the BBB default uboot to be a lot more informative Aug 13 20:35:22 das, i think most people use it for web stuff Aug 13 20:35:42 like echoing more stuff to the terminal about what device it's loading from etc Aug 13 20:35:45 i just like it for the dark themes Aug 13 20:35:54 well there's the vizualization of code in the right that rocks for visual people Aug 13 20:36:05 apart from that I don't see the point really Aug 13 20:36:44 if tried using visual studio ( yes it can work with gcc using the makefile option ) but visual studio now days is waaaay too bloated Aug 13 20:37:06 * das pukes Aug 13 20:37:11 you can do that in the uenv.txt Aug 13 20:37:25 * das eats it again because it tastes better than VS Aug 13 20:37:32 give me vim or give me death! Aug 13 20:37:51 * ds2 slaps mranostay with visual studio Aug 13 20:38:01 never used vim, but I've seen some setups that look visually appealing Aug 13 20:38:18 ds2: you ... you killed him ! Aug 13 20:38:52 once you go vim you can flame Aug 13 20:38:58 ewwww vim Aug 13 20:39:02 *choke* *gag* Aug 13 20:39:07 die emacs lover Aug 13 20:39:12 heh Aug 13 20:39:14 ed > vim Aug 13 20:39:16 I hate emacs Aug 13 20:39:42 edlin ftw ? Aug 13 20:39:46 I wanna say something. I'm gonna put it out there; if you like it, you can take it, if you don't, send it right back... new release of eclipse is actually very clean and very quick Aug 13 20:39:47 * m_billybob ducks Aug 13 20:40:04 * mranostay hurls a dead moose at m_billybob Aug 13 20:40:15 exosyst i like eclipse but detest JVM .. Aug 13 20:40:49 dont like java as a language dont like their virtual machines . ..so i stear clear Aug 13 20:40:54 they all are what they are. VS and Eclipse makes me my bread. Can't hate them for that. Guess I should put xcode in there as well Aug 13 20:41:07 eclipse needs to be rewritten in nodejs Aug 13 20:41:24 VS is hard to beat as an IDE but now days it is far too bloated for my own tastes Aug 13 20:41:30 goge: i rather flip burgers again than deal wiht VS Aug 13 20:41:33 *with Aug 13 20:41:51 VS could also stand more flexability Aug 13 20:41:57 It's not so horrible, an neither is flipping burgers Aug 13 20:41:57 it's as challenging intellectually Aug 13 20:42:26 but each their own :) Aug 13 20:43:04 at least you have a chance of nailing your coworkers at a burger joint Aug 13 20:43:10 * mranostay whistles away Aug 13 20:44:37 goge but your options for "decent" IDE's i think are rather limited. code::blocks or eclipse it seems. You could also use somethign like VIM i suppose but personally i do not view VIM as an IDE but more of a fancy text editor Aug 13 20:44:47 which many text editors can do what VIM does Aug 13 20:44:58 heretic ! Aug 13 20:45:10 heh Aug 13 20:45:17 IDEs are for the weak Aug 13 20:45:25 notepad++ sublime text etc etc Aug 13 20:45:25 I'm looking at the code:blocks site now Aug 13 20:46:08 hah cnotepad++ was half decent when I used windows, would recommend it Aug 13 20:46:38 * mranostay steals one of KotH's bomb belts Aug 13 20:46:43 goge is it nearly as flexible if not as flexable as eclipse. probably slightly less so, but it is not withotu its quirks. setting up a gcc toolchain with it is not unreasonable. though ive found the included gdb functionality not very good. Aug 13 20:47:00 Vim! JIHAD! Aug 13 20:48:07 making template projects with code::blocks is also very easy Aug 13 20:48:42 thats is custom template projects Aug 13 20:48:43 well I'm not hacking kernels, sticking mostly to the javascript chain on the bbb. maybe interop some python, but I will be out of the C/C++ world Aug 13 20:49:10 wait ... there are other languages than C ? Aug 13 20:49:13 ah so if you're not using C/C++ code::blocks is not for you Aug 13 20:49:19 languages without nullpointers are boring Aug 13 20:49:32 snap Aug 13 20:50:26 sublime text vim notepad ++ etc for interprited languages, although im not really familiar with python etc in the context of IDE's Aug 13 20:51:35 how do you push your stuff on the target afterwards ? Aug 13 20:51:37 there is probably even a VS plugin for python, but i wouldnt know anything about it Aug 13 20:51:44 me ? Aug 13 20:51:51 nah goge Aug 13 20:52:10 is there a easy howto on how to flash my custom built rootfs to my bbb? Aug 13 20:52:21 google Aug 13 20:52:42 freinhard other than basic linux commands such as how to use tar etc ? or dd Aug 13 20:52:46 there are plenty, but some don't tell if they are for bb or bbb or do it in all kinds of different ways Aug 13 20:53:30 freinhard lots can be learned by examining the file system structure on your existing BBBs. partitions mainly. Aug 13 20:53:36 m_billybob: i built a rootfs with bitbake. next step would be to get it onto my bbb. but the howto i found needs files i don't have and therefoe i guess it's out of date Aug 13 20:53:49 freinhard, tar it up and copy it to a booting SD card. Boot into the SD card. Format and mount the mmcblk0p1 and extract your rootfs over it Aug 13 20:55:10 exosyst: i've got a 4GB microSD. i've just flashed the 4GB angstrom image to it. it successfully booted from it. Aug 13 20:55:34 exosyst: so you say i just copy my rootfs.tar.bz2 to the ext3 partition on the SD and flash from ther? Aug 13 20:55:51 thats whaty i do Aug 13 20:55:54 something like Aug 13 20:55:56 sudo tar -zcvf ~/rootfs.tar.gz . Aug 13 20:55:56 sudo tar xzvf rootfs.tar.gz -C ~/rootfs Aug 13 20:56:17 in that case i do that for NFS root Aug 13 20:56:39 freinhard, yeah, mkfs.ext3 on /dev/mmcblk, mount /dev/mmcblk /mnt and then tar xvf rootfs.tar.gz -C /mnt Aug 13 20:57:16 exosyst: thx, i'll give it a try Aug 13 21:17:32 Hey there! Aug 13 21:19:22 Anybody... Aug 13 21:19:49 nobody! Aug 13 21:21:56 Damn! Aug 13 21:22:18 yea sucks doesn't it Aug 13 21:22:38 Unbeliable.... Aug 13 21:23:00 I was hoping somebody could give me advice regarding HDMI connection with my BBB. Aug 13 21:23:25 you were? but you got over it? Aug 13 21:24:32 Well... that was when I thought nobody was around. Aug 13 21:25:12 So... Could you? Aug 13 21:26:25 ouch. you just asked if you can ask. Aug 13 21:26:56 a2e http://circuitco.com/support/index.php?title=BeagleBoneBlack_HDMI Aug 13 21:27:06 is all you need Aug 13 21:27:30 Ok. I will re-formulate it. Aug 13 21:27:33 hmmmmm my HVAC BBB has died... :O Aug 13 21:27:51 eep eep no ping.. I hope lightning didn't kill it Aug 13 21:28:19 Vaizki: Can you help me regarding HDMI connecting a Beaglebone black device? Aug 13 21:28:23 Please. Aug 13 21:28:27 I have never done it Aug 13 21:28:34 so probably yes Aug 13 21:28:55 but now I have to leave my beer and run down to the cellar to see my BBB Aug 13 21:29:23 hm a2e can not read Aug 13 21:31:45 gn Aug 13 21:31:52 it's like us helping him. can but won't. Aug 13 21:31:53 nite Aug 13 21:32:04 <_av500_> woglinde: youtube? Aug 13 21:32:18 exact link please Aug 13 21:32:45 the BBB was completely dead, power light was on but no other blinking.. hmm.. weird. Aug 13 21:32:58 i built the systemd-image, should the LEDs blink after boot or do i need to add some daemon to do that? Aug 13 21:38:44 freinhard: well did it boot? Aug 13 21:42:51 So: can anybody help me to deal with this elusive BBB HDMI connection? Aug 13 21:43:12 what's wrong with it? Aug 13 21:43:21 do not ask if you can ask.. grrr.. Aug 13 21:43:37 just throw the question and see if anyone bites Aug 13 21:43:37 Vaizki: well leds start lighting up and stay there Aug 13 21:43:50 freinhard: do you have a serial usb cable..? Aug 13 21:43:56 no, not yet Aug 13 21:44:08 going to get a FTDI tomorrow Aug 13 21:44:11 freinhard, I believe but am not 100% sure that the heartbeat pattern blink is built into the main am355x device tree overlay, so it should blink , but if it doesnt and you can ssh into it obviously that assumption would be wrong Aug 13 21:44:13 good Aug 13 21:44:15 Sorry Vaizki, I have a tendency to do that. It is a regional thing I believe. Aug 13 21:45:28 am335x device tree overlay but . . .you get the idea Aug 13 21:45:53 My BBB seems to be working alright [via VNC, and everything] and when I turn it on connected via HDMI I see the "beaglebone logo, and then briefly a login prompt; after that my display shows "No signal". Aug 13 21:46:17 a2e this could be the infamous Aug 13 21:46:26 BBB has been idle for 20 years glitch Aug 13 21:46:48 So it can output to my display but some configuration prevents it. Aug 13 21:46:51 since the BBB has no RTC you may need to wake it up manually via ssh Aug 13 21:47:22 ive seen the command needed to do this on the beagleboard groups, but i dotn remember it, you should search the beagle board google groups Aug 13 21:47:37 oh you mean disable display sleep? Aug 13 21:48:04 yeah since the rtc doesnt update between boots . . . the system thinks its been a sleep for 20 or so years Aug 13 21:49:06 so goes right into screen saver mode or whatever. maybe some other "thing" could bring it out of sleep aside from the ssh command i saw on the groups, but . . . yeah im not very good with X Aug 13 21:49:23 echo 0 > /sys/class/graphics/fb0/blank Aug 13 21:49:26 My display device even shows a prompt about the resolution being used when the Beaglebone logo is displayed; it reads: "1280x720p 50Hz". Aug 13 21:49:47 it will always do that at boot but once the OS loads . . . Aug 13 21:49:54 BAM sleep mode Aug 13 21:50:06 I meant a "legend", not a prompt. Aug 13 21:50:14 try the command I gave you Aug 13 21:52:19 if that does not work then it could be any number of things, the first that would come to my mind is that something with gdm or applicable window manager needs to be told to display an approproate resolution, or a conf file somewhere needs to be setup for your display. again ive read stuff about this on the groups but have no personal hands on Aug 13 21:52:21 also if you move your mouse or type something on a keyboard it should wake up Aug 13 21:53:25 720p should "just work" though its one of the BBB supported resolutions Aug 13 21:53:50 just noticed it's also in the FAQ.. http://circuitco.com/support/index.php?title=BeagleBone_Black_FAQ Aug 13 21:53:55 not sure if thats 16bit color depth or 24bit though Aug 13 21:53:56 Am I still connected? Aug 13 21:53:57 why don't people read FAQs Aug 13 21:54:02 yes you are Aug 13 21:54:07 Hello... Aug 13 21:56:22 the groups are depressing today Aug 13 21:56:35 depressing most days i guess but meh Aug 13 21:56:39 d00m! Aug 13 21:56:48 hey ka6sox how ya been ? Aug 13 21:56:55 * mranostay trolls Aug 13 21:56:57 tired Aug 13 21:57:09 busy busy eh Aug 13 21:57:11 mranostay: I did not know you were an ACPI freak :-D Aug 13 21:57:14 I see contempt has joined our busy band. Aug 13 21:57:49 [My Firefox keeps crashing!] Aug 13 21:58:06 use a real IRC client ? Aug 13 21:58:25 weechat, irissi mIRC whatever. Aug 13 21:58:38 xchat . . . Aug 13 21:58:40 m_billybob, work is going to be keeping me quite busy... Aug 13 21:58:47 so I'll be around less and less... Aug 13 21:58:57 ka6sox how many sites are you maintaining ? Aug 13 21:59:10 I was using my Firefox browser, now I'm using Chrome. Aug 13 21:59:25 XorA: yeah no comment there :) Aug 13 21:59:29 a browser is still a browser Aug 13 21:59:38 mranostay: BTW there is newer version of that recipe you pushed Aug 13 21:59:50 mranostay: actually uses compilable working source :-D Aug 13 22:00:22 figures Aug 13 22:00:47 ka6sox anyhow however many good though in the context you're getting paid :) Aug 13 22:01:18 mranostay: doesn't look like anyone grabbed yours so I could push it as update tomorrow! Aug 13 22:01:48 ka6sox but yeah wulf is out in Kansas right now settign up a transmitter site too so hes been busier than normal lately too Aug 13 22:01:51 s/push/send/ Aug 13 22:04:27 ka6sox: what were you doing up north? Aug 13 22:05:27 Does anybody here can share his/her expertise with BBB and HDMI? I'm stumbled upon a very basic configuration problem. Aug 13 22:05:34 ds2: I think he was a moose Aug 13 22:06:42 moose days of summer Aug 13 22:20:10 Russ: yo! Aug 13 22:20:22 yo Aug 13 22:20:24 have you used oshpark 4 layer service before? Aug 13 22:20:28 yup Aug 13 22:20:45 is the Tick 4 layer? Aug 13 22:20:52 no, the tick is 2 layer Aug 13 22:20:55 the mite is 4 layer Aug 13 22:20:59 heh Aug 13 22:21:02 mite? Aug 13 22:21:22 http://www.flickr.com/photos/russdill/sets/72157629587973588/ Aug 13 22:22:03 an oshpark 4 layer beaglebone cape would be kinda pricey Aug 13 22:22:17 yeah figured Aug 13 22:22:33 probabaly will do a none standard cape size instead Aug 13 22:23:16 Russ: so reflow, eh? Aug 13 22:23:18 a set of 3 of a 2 layer cape was $42.15 (including a small coupon to make applying paste easier) Aug 13 22:23:31 reflow is really the only way to fly Aug 13 22:23:51 oshstencils as well? Aug 13 22:24:14 I have an oshstencil for an ina226 breakout board that I have, but I haven't had time to try it out yet Aug 13 22:24:22 my previous stencils were from ohararp Aug 13 23:15:02 Can anyone here think of a logical reason why the bbb might cause 1.5 ghz interference? Aug 13 23:18:53 Willdude123: there are lots of reasons that it might Aug 13 23:19:01 Willdude123: pwm setup incorrectly Aug 13 23:19:14 Willdude123: pll set incorrectly Aug 13 23:19:21 Willdude123: improper grounding Aug 13 23:19:38 Sure. Aug 13 23:19:39 Willdude123: a badly designed and/or prototyped cape connected Aug 13 23:19:57 Improper grounding? Meaning? Aug 13 23:21:17 Willdude123: improper grounding: power supply is not grounded, cape inserted onto the bbb is not grounded, hdmi display connected to the bbb that does not have proper grounding Aug 13 23:21:33 Right Aug 13 23:21:51 Willdude123: how are you determining that you have 1.5GHz EMI coming from the bbb? Aug 13 23:21:56 sharp edges Aug 13 23:22:03 ds2: hehe Aug 13 23:22:19 I have a gps module that is jammed by it Aug 13 23:22:21 Willdude123 is having problems with GPS Aug 13 23:22:34 how many dbm's is the 1.5GHz signal? Aug 13 23:22:38 That needs almost no signal power to disrupt it Aug 13 23:22:40 0dbm? Aug 13 23:22:45 -90dbm? Aug 13 23:23:05 GPS is -140dbm at the antenna IIRC Aug 13 23:23:23 There is coding gain after this - so it's somewhat more jam resistant. Aug 13 23:23:30 But still... Aug 13 23:23:30 what's is the coding gain? Aug 13 23:23:42 GPS should be mostly immune to single frequency jamming Aug 13 23:23:48 Between a thousand and 20000, dependant on stuff Aug 13 23:23:57 It's not. Aug 13 23:23:58 dbs or is htat a ratio? Aug 13 23:24:05 ratio Aug 13 23:24:08 heh - 1000dB Aug 13 23:24:13 that's a lot Aug 13 23:24:27 1000 is 30dB Aug 13 23:24:37 The coding gain gets you maybe 40dB on a good day. Aug 13 23:24:39 so about 30-40 dB Aug 13 23:24:54 got a spec an? Aug 13 23:24:59 But -100dBm after coding gain isn't much. Aug 13 23:25:05 see if it is a characteristic square wave spectrum Aug 13 23:25:22 sweep from like 500MHz up to 5GHz Aug 13 23:25:26 In short - signals can be generated at harmonics of the various bus freqeuncies in the BBB Aug 13 23:25:59 And these signals can be quite adequate to swamp GPS - while not failing emissions testing. Aug 13 23:26:33 SpeedEvil: indeed Aug 13 23:26:37 still, what's the spectrum looking like? Aug 13 23:26:52 ds2: He doesn't have a nice spectrum analyser. Aug 13 23:27:04 ds2: Simply knows that his GPS module doesn't work when the BBB is on. Aug 13 23:27:25 Spectrum analysers are annoyingly pricey. Aug 13 23:27:37 not really Aug 13 23:27:50 ds2: really Aug 13 23:27:51 i got one for $300 Aug 13 23:27:57 its not bad. Aug 13 23:28:07 you can throw together one for about $20-$30ish Aug 13 23:28:34 ds2: One that can measure -100dBm class signals over that frequency range? With no testgear or intermod problems? Aug 13 23:28:59 what signals are at -100dBm Aug 13 23:29:02 Because if you have a spectrum analyser with intermod problems you now have three fun problems. Aug 13 23:29:15 JFK911: hypothetical interfering signals for GPS. Aug 13 23:29:17 JFK911, most receiver signals are much less than that. Aug 13 23:29:32 http://www.edn.com/design/failure-analysis/4389545/Can-a-129-spectrum-analyzer-be-any-good Aug 13 23:30:31 no, you look for strong signals Aug 13 23:30:56 i.e. if you see a characteristic square wave spectrum, you can extrapolate out a little bit and have a candidate interferer Aug 13 23:31:10 yeah my machine doesnt work so hot below -100; i think -120 is its limit with a narrow span Aug 13 23:31:23 but its got a honking attenuator on the input Aug 13 23:31:29 you don't need perfect tools. you just need to understand things Aug 13 23:31:38 ds2: bingo Aug 13 23:31:41 ds2: Quite. Aug 13 23:32:18 but this cheap spectran is part of a test set that is more about generating minute signals and checking out large ones Aug 13 23:33:12 Checking - I find GPS is -140dBm at a typical antenna - so -100dBm to -110dBm for a pure tone jammer signal is probably in the ballpark. Aug 13 23:33:21 Which isn't really a lot. Aug 13 23:33:37 Shielding and some ferrite beads would probably be a first stab. Aug 13 23:33:50 -140 is pretty close to absolute zero? Aug 13 23:34:01 It's below the thermal noise Aug 13 23:34:29 GPS is fun! Aug 14 00:01:12 hmm Aug 14 00:25:07 SpeedEvil: it is? Aug 14 00:25:28 yes Aug 14 00:25:44 * SpeedEvil has several partial GPS receiver designs Aug 14 01:35:21 hey guys .. anyone know how to add gadget-init from mesa-beagleboard to my custom layer in yocto? Aug 14 01:43:46 hi there, anyone know how to include mesa-beagleboard recipes Aug 14 01:54:21 there should something like bblayers.conf Aug 14 01:54:22 edit that Aug 14 01:54:24 IIRC Aug 14 01:58:31 hi, i have included it ok, but on boot it says I am missing g_ether module Aug 14 01:59:47 actual error is: FATAL: Module g_ether not found. Aug 14 02:00:12 is that a kernel module I have to configure? Aug 14 02:03:33 i see the gadget-init inherits systemd, does that mean I have to change my build to systemd? Aug 14 02:03:39 if so how do I do that? Aug 14 02:45:33 * mranostay trolls ds2 **** ENDING LOGGING AT Wed Aug 14 02:59:59 2013
