**** BEGIN LOGGING AT Thu Jul 11 02:59:58 2013 Jul 11 03:27:46 Spirilis you still around ? Jul 11 03:33:03 <_av500_> old ROMs use openGL? Jul 11 03:33:17 MAME uses ogl, or can Jul 11 03:33:27 uses Direct3D on windows Jul 11 03:34:44 <_av500_> yes, but what for? Jul 11 03:35:56 the games are emulated through MAME, many of these games were made to run on pure hardware. Thats tough to emulate in a timly fashion on other hardware Jul 11 03:37:28 anyway, hardware acceleration does help Jul 11 03:38:33 <_av500_> m_billybob: probably not much more than a glorified blitter Jul 11 03:38:50 <_av500_> as in get the pixels into the framebuffer fast Jul 11 03:38:57 av500 perhaps but every little bit that can be offloaded from the processor will help Jul 11 03:39:25 <_av500_> it might help for the vectrex Jul 11 03:40:07 <_av500_> anyways, sgx will be there soob Jul 11 03:40:09 <_av500_> soon Jul 11 03:40:11 it'll help some, how much exactly im not sure Jul 11 03:40:15 yeah Jul 11 03:40:20 quater 4 this year Jul 11 03:40:26 so sayeth TI Jul 11 03:40:43 quarter 4 even Jul 11 03:41:19 some of these games wont even play well on an intel i7 Jul 11 03:41:28 those games i probably wouldnt bother with Jul 11 03:42:22 but i think for most if not all of the 80's era games it'll be just fine Jul 11 06:06:59 i am accesing BBB from my host pc shell Jul 11 06:07:06 using ssh command Jul 11 06:07:21 i hav connected bbb to pc via usb Jul 11 06:07:54 but i want GUI for the same arrangement Jul 11 06:08:06 how can i achieve this?

Jul 11 08:16:53 I'm wondering what to do with the pile too Jul 11 08:17:34 av500: a VIC20 ? Jul 11 08:18:33 yes Jul 11 08:18:52 I've seen someone fitting small boards inside Jul 11 08:19:42 av500: mount them on one of your walls and call it modern art Jul 11 08:21:22 maybe Jul 11 08:21:58 av500: make it a twitter appliance ;) Jul 11 08:22:19 put a beagle inside Jul 11 08:22:21 jaja Jul 11 08:22:23 I know Jul 11 08:22:33 stuff it with explosives and light it up Jul 11 08:23:31 IRC terminal client Jul 11 08:23:34 av500: sell it by weight Jul 11 08:24:49 dm8tbr: lacks display Jul 11 08:24:52 ah well Jul 11 08:24:54 old TV Jul 11 08:24:56 have that too Jul 11 08:25:00 -ETOOBIG Jul 11 08:25:21 there is a PLUS/4 too Jul 11 08:25:40 oh Jul 11 08:25:44 and a Sony HitBit Jul 11 08:26:31 hehe Jul 11 08:26:55 attach the composite out to a frame grabber and route it back to your desktop ;) Jul 11 08:42:19 av500: about vintage stuff from that period, I found my old 1984 integrated amplifier. Now, friends say I have to exchange the two big capacitors on it as precaution Jul 11 08:42:49 did 1980's stuff rot quickly? Jul 11 08:43:02 ant_work: 1980s isn't quickly. Jul 11 08:43:24 ant_work: it depends Jul 11 08:43:29 well, forever young ;) Jul 11 08:43:33 ant_work: A capacitor not used for several years may depolarise somewhat. And not be able to sustain its nominal vcc Jul 11 08:43:33 some caps are still good Jul 11 08:43:35 some are not Jul 11 08:43:55 It is a generally good plan for big power caps to gradually raise the voltage. Jul 11 08:44:15 but then, caps are cheap Jul 11 08:44:21 replacing them is no big deal Jul 11 08:44:24 I had a large 12V/40A early SMPS with a _massive_ front cap vent. Jul 11 08:44:40 The smell lasted for ages, and I question how healthy it is. Jul 11 08:44:43 I found the service manual but can't find the BOM Jul 11 08:44:56 ant_work: what is it? Jul 11 08:45:05 You look at teh numbers on the side. Jul 11 08:45:17 Alternatively, you can power it up outside for a day. Jul 11 08:45:19 it's a JVC-ax400 superA Jul 11 08:45:24 http://www.eserviceinfo.com/download.php?fileid=47523 Jul 11 08:45:43 ant_work: the caps will have ratings on the sides of them. Jul 11 08:46:35 I fear I'll broke the plastic parts, it's not so elastic after much time Jul 11 08:46:43 dismounting it Jul 11 08:47:46 10000u/63V Jul 11 08:47:51 its in the schematics Jul 11 08:49:07 oky thx Jul 11 08:49:21 ant_work: I would just try it out Jul 11 08:50:21 there are also a few other smaller caps Jul 11 08:51:11 maybe better to send it to service center and have it tested and calibrated Jul 11 08:51:19 is it worh it? Jul 11 08:51:21 worth Jul 11 08:51:49 well, if repair is 50-100 Eur prolly yes Jul 11 08:53:16 av500: afaik mid-80 quality was not the same as end '70. This for Pioneer/Marantz/JVC Jul 11 08:53:36 (talking about integrated amps) Jul 11 08:53:54 hi guys anyone ther to help me on a reciever code for gsm module in BBB Jul 11 08:54:44 how much do you pay?

Jul 11 09:08:54 we're here, but don't have magic answers I'm afraid Jul 11 09:09:05 is there not an AT command to check for new messages? Jul 11 09:09:25 I don't know what your hardware is, how it works or the AT commands it supports, so I don't know how we can help you... Jul 11 09:10:25 im using a BBB with 2 pins i configured tx n rx which i have connect to GSM SIM900 module Jul 11 09:10:40 http://www.developershome.com/sms/checkCommandSupport2.asp Jul 11 09:10:42 with the previous code of sending msgs it works Jul 11 09:10:43 use google Jul 11 09:10:54 want a reciever logic Jul 11 09:11:05 google for sms reciever logic Jul 11 09:11:23 http://www.codeproject.com/Articles/38705/Send-and-Read-SMS-through-a-GSM-Modem-using-AT-Com Jul 11 09:11:38 there you go, both those pages are the first two hits in google. read them. Jul 11 09:12:35 went through second link... Jul 11 09:12:44 vin_: your pastebin URL is bad Jul 11 09:12:45 will read more from the first link Jul 11 09:13:26 av500 it says paste is removed wait i will paste it again Jul 11 09:13:29 av500: it was just sending AT commands over a serial device Jul 11 09:13:50 in unindented code Jul 11 09:14:32 http://pastebin.com/KhuxtnUK Jul 11 09:15:27 @jack how else shld i code?? Jul 11 09:15:49 leave the printf statements tats for my references i put Jul 11 09:16:38 vin_: you should at least use consistent indentation Jul 11 09:16:48 it makes code a lot easier to read and follow Jul 11 09:17:42 ok jackmitchell hences forth will surely follow tat way... Jul 11 09:17:49 sorry :( :( Jul 11 09:18:04 vin_: just a suggestion, I wouldn't take it personally! Jul 11 09:18:24 vin_: while not specifically for C, have a little read of this http://net.tutsplus.com/tutorials/html-css-techniques/top-15-best-practices-for-writing-super-readable-code/ Jul 11 09:18:35 ok jack... Jul 11 09:18:36 vin_: what is your max Jul 11 09:18:56 max232 Jul 11 09:19:24 thanks jack for tat link will follow tat...! Jul 11 09:20:53 electronics design got easy Jul 11 09:21:47 kind off simple 3 wire from BBB Jul 11 09:25:42 vin_: so, find out what is the AT command to query for SMS Jul 11 09:25:45 and implement it Jul 11 09:25:58 thats not really beagle specific Jul 11 09:26:10 I hear it's so popular there is even a 3GPP standard for this... Jul 11 09:28:28 ya its not beagle specific i wanted help weither anyone is tried or has a idea of recieveing it... Jul 11 09:31:02 as said, its AT commands Jul 11 09:31:42 * dm8tbr has done it in the past manually. terminal, spec in hand. Jul 11 09:31:45 it's not hard Jul 11 09:51:16 dm8tbr: getting a modem working is a lost art ever since dial up connections died out Jul 11 09:54:00 hi. When using my beaglebone on my TV it works perfectly well. When I start playing music and then plug it onto my hifi system, the music is played on it also very well Jul 11 09:54:27 just until mplayer exits because of EOF - when then restarting it with the same song it won't play any music then Jul 11 09:54:41 KotH: don't you use dial up .ch Jul 11 09:56:03 we did, 15y ago. then broad band connections came Jul 11 09:56:14 KotH: since most wireless modems still speak AT it's not completely lost. I personally find it quite ridiculous, that there is a PPP connection from the host to the modem and that unpacks it and forwards raw IP to the network... Jul 11 09:56:48 dm8tbr: design by "so is' worden" :) Jul 11 09:56:57 yeah Jul 11 09:57:12 yup Jul 11 09:57:14 I'm not surprised that there are not more cdc-ether type modems around Jul 11 09:57:24 I've seen a few Jul 11 09:57:37 s/not// Jul 11 09:57:49 we use ip over dogs in NZ Jul 11 09:58:11 not over sheep? Jul 11 09:58:28 they are used for other "things" Jul 11 09:58:33 yeah and the dogs are for QoS and traffic shaping ;) Jul 11 09:58:46 har har baaaaa Jul 11 09:58:58 i enjoyed my roast lamb Jul 11 09:59:17 is there maybe some HDMI initialization to be done? Jul 11 10:01:38 dolor1: explain Jul 11 10:01:52 you unplug while playing? Jul 11 10:01:59 and replug into your hifi? Jul 11 10:03:01 exactly Jul 11 10:03:18 and then it works just as long as mplayer doesnt exit because the song ends Jul 11 10:03:38 as soon as this happens and you want to restart mplayer with another track, you won't hear a thing Jul 11 10:03:49 then I have to reboot the BBB with my TV connected and so on Jul 11 10:04:14 I am wondering how to do this HDMI initialization, which is done at boot-time, by myself Jul 11 10:04:27 * dm8tbr puts bets on EDID etc Jul 11 10:04:32 yeah Jul 11 10:04:48 cant your hifi pass through the HDMI? Jul 11 10:04:54 BBB -> hifi -> HDMI Jul 11 10:04:57 er Jul 11 10:05:00 BBB -> hifi -> TV Jul 11 10:05:17 it's a hdmi "audio extractor" from Ligawo Jul 11 10:05:21 and yes it can pass through Jul 11 10:05:26 ic Jul 11 10:05:45 it is strange that it works at all Jul 11 10:05:53 why shouldn't it? Jul 11 10:05:56 normally when you unplug hdmi, it should stop Jul 11 10:06:08 and a replug would make a new hdmi connection Jul 11 10:06:15 probably the audio interface being in use keeps it alive? Jul 11 10:06:17 but I dont know what exactly happens Jul 11 10:06:20 dm8tbr: yes Jul 11 10:06:27 dont know the details there Jul 11 10:06:36 anyway, what you want it to have only the audio thing Jul 11 10:06:40 which might be a kernel bug Jul 11 10:06:46 so how can I establish a new connection? Jul 11 10:06:56 you would need to debug it Jul 11 10:07:04 find out what your extractor reports Jul 11 10:07:19 maybe without a TV it does not report EDID at all Jul 11 10:07:30 so you need HDMI with a fake EDID Jul 11 10:07:37 dont know if that is possible yet Jul 11 10:07:39 koen: ^^^ ? Jul 11 10:07:42 jkridner|work: ^^^ ? Jul 11 10:08:21 oh wow, that sounds just a bit too high for me. I thought these devices all would work together Jul 11 10:08:33 well Jul 11 10:08:38 no idea what your extractor does Jul 11 10:08:46 it's a EPMI EP91A1K chip Jul 11 10:09:44 it extracts the audio from HDMI signal and then it is converted using a DAC Jul 11 10:10:09 can you get chocolate out of the hdmi? Jul 11 10:10:24 dolor1: yes Jul 11 10:10:26 audio cape works well as well Jul 11 10:10:28 it has support for EDID Jul 11 10:10:38 question is, what does it do without a TV Jul 11 10:10:50 dolor1: so, in passthrough, does it work? Jul 11 10:10:59 i will try right now Jul 11 10:11:14 hmm, it says EDID RAM Jul 11 10:11:21 I wonder if it caches the TV EDID in RAM Jul 11 10:11:24 as long as it is powered Jul 11 10:11:31 try that Jul 11 10:11:43 BBB -> EPMI -> TV Jul 11 10:11:49 then power off the TV Jul 11 10:11:52 I always have to reboot Jul 11 10:11:53 and reboot the BBB Jul 11 10:12:08 maybe EPMI caches the proper EDID Jul 11 10:12:41 http://circuitco.com/support/index.php?title=BeagleBoneBlack_HDMI#EDID_Information Jul 11 10:12:45 dolor1: see ^^^^ Jul 11 10:13:16 so now it runs using the TV Jul 11 10:13:21 passthrough? Jul 11 10:13:25 yes Jul 11 10:13:27 ok Jul 11 10:13:30 everything ok. Jul 11 10:13:33 now turning off TV Jul 11 10:14:09 still works Jul 11 10:14:27 I can start mplayer and close it and it will always play music Jul 11 10:14:50 now reboot the BBB Jul 11 10:14:59 leave the EPMI powered Jul 11 10:16:08 .. but the TV off? Jul 11 10:16:32 av500 Jul 11 10:16:43 yes Jul 11 10:17:06 trying to find out if the EPMI caches the EDID info Jul 11 10:17:22 I see Jul 11 10:17:41 it does. works all fine Jul 11 10:17:59 even if you reboot? Jul 11 10:18:06 yes Jul 11 10:18:09 ok Jul 11 10:18:10 good Jul 11 10:18:13 leave it powered :) Jul 11 10:18:58 mhm. not very satisfying Jul 11 10:19:08 there's no work-around you could suggest? Jul 11 10:21:21 but thank you very much, av500. I've got a greater understanding of HDMI now Jul 11 10:21:43 [kernel] koenkooi pushed 2 new commits to 3.8: http://git.io/gu8hFQ Jul 11 10:21:43 kernel/3.8 4099492 Koen Kooi: 3.8: add leds-pwm patches and bacon cape support... Jul 11 10:21:43 kernel/3.8 65fb545 Koen Kooi: 3.8: update beaglebone config... Jul 11 10:22:02 not for now Jul 11 10:22:15 HDMI assumes a proper EDID Jul 11 10:22:28 your box does not deliver one unless it saw a TV and cached the TV one Jul 11 10:22:36 makes sense for a passthrough scenario Jul 11 10:22:47 one could fake an EDID on the BBB side Jul 11 10:22:54 but I dont think the SW is there yet Jul 11 10:23:23 if I figure out how to do, I'll inform you Jul 11 10:24:30 drm has a way to fake the EDID, but I haven't tried it myself Jul 11 10:24:51 there was talk about an small board with 2 hdmi plugs and an eeprom to act as a pass through Jul 11 10:25:15 what does drm stand for? Jul 11 10:25:36 direct rendering mechanism or something Jul 11 10:25:46 it's a linux kernel framework for displays and stuff Jul 11 10:26:58 ah ok. Jul 11 10:26:58 (Direct Rendering Manager Jul 11 10:27:14 as soon as managment is involved, stuff goes downhill Jul 11 10:27:54 somebody called for management? ;) Jul 11 10:28:40 * KotH manages dm8tbr Jul 11 10:28:47 so I could use a µC which fakes the EDID of my monitor, if I knew how HDMI worked Jul 11 10:29:11 isnt the edid data transfered over i2c ? Jul 11 10:29:14 or you could tell your BBB to ignore the EDID and use your own Jul 11 10:29:15 yes Jul 11 10:29:18 yes Jul 11 10:29:29 then it shouldn't be too hard Jul 11 10:29:35 .o0(was heisst hier ja ja?) Jul 11 10:29:38 dolor1: you could just solder an I2C eeprom to the HDMI I2C lines Jul 11 10:29:44 KotH: does that make me a managed management service? Jul 11 10:30:06 M2S Jul 11 10:30:12 do we have an M2S manager? Jul 11 10:30:17 dm8tbr: i can give you a certificate stating that you are managed properly for a couple of $$$ Jul 11 10:30:22 av500, I thought it wouldn't be a good idea to floss HDMI cables Jul 11 10:30:27 floss? Jul 11 10:30:34 KotH: I'd offer some chocolate instead Jul 11 10:30:47 I could manage some chocolate now Jul 11 10:30:51 bearely Jul 11 10:30:55 don't know how the word is in english... Jul 11 10:30:55 dm8tbr: you're in finland, you have no high quallity chocolate source Jul 11 10:31:06 KotH: fazer is reasonably good Jul 11 10:31:18 dm8tbr: that's mine to decide! Jul 11 10:31:19 ;) Jul 11 10:31:27 when you connect wires out of a cable by soldering Jul 11 10:31:31 yes, next time we meet Jul 11 10:31:43 because high-speed HDMI Jul 11 10:31:53 nah Jul 11 10:31:54 dolor1: you could fly the wires on the PCB Jul 11 10:31:55 its fine Jul 11 10:32:06 coworker split an HDMI cable for CEC Jul 11 10:32:08 or maybe that I²C is even on the expansion connectors Jul 11 10:32:11 worked fine afterwards Jul 11 10:32:19 dm8tbr: not this one Jul 11 10:32:21 afaik Jul 11 10:32:36 well, enamel wires to the pads then Jul 11 10:33:13 put a switch in to turn it on and off as needed. unless it's going to be like that for ever Jul 11 10:33:41 or solder it inside the EPMI box Jul 11 10:33:55 but I would just open a cable Jul 11 10:33:58 I think I also saw a patch allows you to embed the EDID into the DT Jul 11 10:33:59 and get to the pins Jul 11 10:34:05 koen: even better Jul 11 10:34:06 not sure if that one got accepted Jul 11 10:34:13 it sounds usefull Jul 11 10:34:16 so maybe not Jul 11 10:35:50 lunch Jul 11 10:35:51 pins 15, 16 right? Jul 11 10:36:25 on hdmi? Jul 11 10:36:27 morning, channel Jul 11 10:36:33 17,18 Jul 11 10:36:39 morning fuzzy Jul 11 10:36:49 * bradfa is all warm and fuzzy Jul 11 10:37:09 17, 18 on beaglebone-side (type D connector) Jul 11 10:37:19 right? Jul 11 10:37:22 yes Jul 11 10:37:31 will try this :) Jul 11 10:37:58 I would just patch the "read_edid()" function in the kernel Jul 11 10:38:17 hardcode it in the board file Jul 11 10:38:26 board files ftw Jul 11 10:38:28 +1 Jul 11 10:38:37 we don't need no stinking generic frameworks Jul 11 10:38:40 but... I don't know how to Jul 11 10:38:46 then .... solder Jul 11 10:38:51 you still need to write that eeprom Jul 11 10:38:59 unless you desolder the one from your TV Jul 11 10:39:38 mhm... I will find out which way works best for me Jul 11 10:39:45 http://lists.freedesktop.org/archives/dri-devel/2012-June/024600.html Jul 11 10:39:48 koen: ^^^ Jul 11 10:40:01 https://plus.google.com/109348954914940290321/posts/7H1JU5Y7GYX Jul 11 10:40:07 oops Jul 11 10:40:10 not public Jul 11 10:40:12 ignore Jul 11 10:41:20 heh, I commented on that Jul 11 10:41:33 anywaylaters Jul 11 10:41:38 another problem: Jul 11 10:41:53 after a few minutes I have to reboot my BBB to establish a new HDMI connection Jul 11 10:42:07 sorry, only one problem per day Jul 11 10:42:12 :< Jul 11 10:42:16 we have a strict quota Jul 11 10:42:23 MGT issues... Jul 11 10:42:59 then I'll just come back tomorrow. :) Jul 11 10:43:19 we have your IP Jul 11 10:43:23 :) Jul 11 10:43:37 (or found out the solution by tomorrow already) Jul 11 10:43:42 so what? Jul 11 10:49:22 cya and thank you again Jul 11 11:50:57 av500: indeed, that's the patch I was thinking about Jul 11 12:26:16 The RS-485 specification recommends connecting a 100-ohm resistor of at least 1/2 Watt in series between each node's signal ground and the network's ground wire, as the circuit above shows. This way, if the ground potentials of two nodes vary, the resistors will limit the current in the ground wire. Jul 11 12:26:31 That is the suggestion to take care of small ground loops Jul 11 12:26:48 This should be handy when your phone battery dies Jul 11 12:26:51 http://www.youtube.com/watch?feature=player_embedded&v=brdmnUBAS00 Jul 11 12:28:17 . Jul 11 12:31:37 hi Jul 11 12:32:41 R2E4 : I assume that is if you do not galvanicly isolate the receiver ? Jul 11 12:33:27 i dont understand Jul 11 12:33:38 i am new to this chat Jul 11 12:33:46 how is this working? Jul 11 12:33:53 hello sree__ Jul 11 12:34:00 hi Jul 11 12:34:38 i want to download a source code for bb black Jul 11 12:34:44 can u pls help me Jul 11 12:36:57 Crofton: me missed to say to orient the empty battery at the bottom Jul 11 12:37:10 hmmm Jul 11 12:37:30 chocolate now or later Jul 11 12:37:44 * koen is trying out the delayed gratification concepts Jul 11 12:38:18 dm8tbr, i just fixed my problem using new built u-boot and uEnv.txt created by myself, now i can boot sitara linux (from TI) from emmc. :) Jul 11 12:40:25 av500, Jul 11 12:40:33 how can I clone this git repo ? https://github.com/beagleboard/kernel/tree/3.8 Jul 11 12:40:53 i can't its url for my clone Jul 11 12:43:08 it says "git clone url" Jul 11 12:43:12 on the right Jul 11 12:45:44 thanks Jul 11 12:45:47 i just find it Jul 11 12:46:28 koen: research shows, that if you can work with delayed gratification, you will be more successful Jul 11 12:46:52 koen: unfortunately, this research was mostly done with kids below the age of 10 Jul 11 12:47:05 koen: the applicability to adults is thus questionable :) Jul 11 12:48:12 KotH: didnt they show that the kids that were good at 10 did well in school too? Jul 11 12:50:53 KotH: It's not Jul 11 12:51:10 KotH: Those kids were tracked throughout much of their life - it persists. Jul 11 12:52:44 http://en.wikipedia.org/wiki/Stanford_marshmallow_experiment Jul 11 12:52:55 I don't see the links I was thinking of. Jul 11 12:53:11 But behaviour at 2-3 has been found to be largely predictive in many ways of later behaviours. Jul 11 12:53:39 another study related to that is also interesting Jul 11 12:53:47 they did the test but cheated at gratification Jul 11 12:53:54 kids then stopped trusting Jul 11 12:54:12 thus you need to be sure that gratification is there Jul 11 12:54:19 in order for it to work Jul 11 12:54:30 http://rstb.royalsocietypublishing.org/content/362/1480/507.full - is also fascinating. Jul 11 12:54:37 Scrub jays cache food for later. Jul 11 12:54:42 Some birds steal food. Jul 11 12:55:05 In general, birds only realise that other birds might steal food, after doing it themselves. Jul 11 13:10:54 hi, has anyone ever had issues with journald hogging bandwidth? Jul 11 13:15:07 * KotH would not be surprised Jul 11 13:15:24 mru: someone is asking for some lennart bashing Jul 11 13:16:22 can't be arsed Jul 11 13:30:18 OWayne: In what way Jul 11 13:30:52 OWayne: io bandwidth? Jul 11 13:31:05 to the disk? Jul 11 13:32:59 bullshit bandwidth Jul 11 13:34:24 journald kicks ass Jul 11 13:34:54 * georgem pours some gasoline on the campfire Jul 11 13:36:05 perhaps something is just logging a lot Jul 11 13:36:41 maybe its the journald logs? Jul 11 13:36:43 suihkulokki: If you have your rate limit settings configured correctly in /etc/systemd/journald.conf journald is design to handle that Jul 11 13:37:02 maybe it is logging that the rate limit has been reached? Jul 11 13:37:12 lol Jul 11 13:37:21 if so I'll buy mru a beer Jul 11 13:37:47 so he gets a beer and I just get a lol? Jul 11 13:38:22 fine, you get one too Jul 11 13:38:35 good Jul 11 13:38:41 * av500 calls off the hit men Jul 11 13:39:34 georgem: what's the point in rate limiting logging, and thus loosing valuable information? Jul 11 13:40:11 georgem: imho a logging daemon should be handle as much data rate as it can write to its destination device, whatever that might be Jul 11 13:40:35 what if its out of carrier pidgeons? Jul 11 13:40:49 stop the CPU and breed new ones? Jul 11 13:41:00 then i go to the next store, and buy another couple thousand pidgeons Jul 11 13:41:50 but seriously, i had systems with a dedicated Gbit interface for syslog to send its messages out Jul 11 13:42:08 too bad that gbit is broken on BBB Jul 11 13:42:15 KotH: It can be used for denial of service attacks. If you have your limits set correctly and you're monitoring logs you'll get plenty of notice that something is f'd so you can fix it immediately. Jul 11 13:42:16 and what maxed out was the process generating these messages, not syslog, not the interface Jul 11 13:42:18 maybe one can bitbang a syslog cape? Jul 11 13:42:41 farfanugen Jul 11 13:42:47 av500: GMII signals are only 125MHz, so you can do it with a PRU Jul 11 13:43:06 KotH: if you don't need it/want it off. that's why its a setting Jul 11 13:43:07 does someone know where gpio numbering gets set in the Linux kernel, I have looked in the GPIO driver and I can't see it, the devicetree doesn't set it... any clues on where to look? Jul 11 13:43:55 georgem: i'm critizizing the need for such a limit in the first place. it tells me that logingd is inefficient enough that it can be maxed out Jul 11 13:44:10 you mean journald Jul 11 13:44:19 er.. yes, journald Jul 11 13:44:37 chocomotor must have run out of chocolate Jul 11 13:44:40 brb Jul 11 13:45:25 KotH: its all relative. If you're running on a low power ARM server without much network bandwidth its going to max out earlier than a 12 core xeon with 10GBe Jul 11 13:46:19 anyone know any great accessories to invest in for the beagle bone black? Jul 11 13:46:55 KotH: actually... I think these limits only apply to journal file output not syslog forwarding (not sure about that) so this may just be to limit disk usage. Jul 11 13:47:30 georgem: hmm... Jul 11 13:48:01 scoobs: collar with diamonds, maybe? Jul 11 13:49:26 haha Jul 11 13:49:35 I need to find some screws and standoffs for mine Jul 11 13:49:57 I had some lexan cut to make a case/base for it just for a little protection Jul 11 13:50:01 but I need to mount it now Jul 11 13:50:52 http://elinux.org/BeagleBone#Cases Jul 11 13:51:18 but i would still go for the collar Jul 11 13:51:37 I will but first I got to get the little guy a dog house Jul 11 13:51:56 made out of solid gold? Jul 11 13:52:05 FWIW on my embedded systems logging to flash you really want to be careful because flooding stuff to the logs can really bottle neck system performance and induce excessive flash wear. The rate limiting feature is very useful for dealing with this. Jul 11 13:52:07 no just lexan clear Jul 11 13:54:58 moo Jul 11 13:55:06 got milk? Jul 11 13:55:19 naw, have to lay off for a while Jul 11 13:55:37 * m_billybob drinks too much milk Jul 11 13:56:59 as long as it's not carrots Jul 11 13:57:06 georgem: im back. If there are a lot of messages jornald can stat eating up the rest of the cpu bandwidth. I have conf setup so no logs are written because I am forward nessages on to ryslog to be passed over the network Jul 11 13:57:54 OWayne: can you paste your journald.conf Jul 11 13:58:03 sure, 2 ticks Jul 11 13:58:32 also would be helpful to know which version of systemd you're running Jul 11 13:59:53 v189 grabbed via angstrom Jul 11 14:00:31 http://pastebin.com/CVNfzvka Jul 11 14:02:05 The rate settings have been tweaked with little effect. The only thing that works for me is to silence as much debug as possible, which I guess is a good thing Jul 11 14:05:11 that is quite unsettling, i'm looking into it... Jul 11 14:05:38 georgem: I did come across this mailing list http://lists.freedesktop.org/archives/systemd-devel/2013-February/009137.html which seems to point to systemd not being very well optimised for embedded systems Jul 11 14:10:46 OWayne: I'm going to paste a few commits that have been made since the version you're using which could improve performance Jul 11 14:10:52 http://cgit.freedesktop.org/systemd/systemd/commit/src/journal?id=c2457105d76e3daf159f554a9bafb9751b23d756 Jul 11 14:10:57 http://cgit.freedesktop.org/systemd/systemd/commit/src/journal?id=a569398925430de1f8479262e8ab39502054f2e9 Jul 11 14:11:01 http://cgit.freedesktop.org/systemd/systemd/commit/src/journal?id=adb435bb70815461eeddf44dd5d6f1fc2ad9026d Jul 11 14:11:05 http://cgit.freedesktop.org/systemd/systemd/commit/src/journal?id=0a20e3c10761378869af7bbef2733e3ae879d0f1 Jul 11 14:11:09 hello mr das_plague Jul 11 14:25:23 KotH: if we watched the same research video I really like the girl that only at the inside of the marshmellow Jul 11 14:28:27 koen: i didnt watch any video... it was part of a lecture i had to take :) Jul 11 14:28:37 koen: but i'd like to have a link to the video, if you have Jul 11 14:29:47 KotH: I think it was this one: http://www.ted.com/talks/joachim_de_posada_says_don_t_eat_the_marshmallow_yet.html Jul 11 14:30:11 koen: ah.. taht one Jul 11 14:30:18 koen: juup, that girl is cool :) Jul 11 14:35:59 koen: what's the status of A. v2013.06-yocto1.4 ? Need more testing? Jul 11 14:37:53 koen: btw 2012.12's systemd-image seemd booting much faster than console-image on those ancient pda's Jul 11 14:40:58 ant_work: more testing and the texinfo5+ and gcc 4.8 backports Jul 11 14:54:47 Is there a script or instructions to compile/cross-compile Qt, hopefully even Qt5, for the default BBB's Angstrom? (I know it isn't too hard to do from scratch, but it is a pain.) Jul 11 14:58:17 is there any difference on how you enable and disable capes when you're running from SD or eMMC? Jul 11 15:09:43 av500, was that a Zenit the Russians blew up recently? Jul 11 15:10:19 ka6sox: proton-m Jul 11 15:11:22 ah Jul 11 15:12:56 ka6sox: no, it did not reach it's zenit Jul 11 15:13:03 it blew up way before Jul 11 15:14:01 av500, heh Jul 11 15:14:19 looked like a guidance failure or one of the motors cut out Jul 11 15:16:13 ka6sox: upside down mounted sensor Jul 11 15:16:26 that threw off the guidance Jul 11 15:17:43 well it almost managed to turn around the sensors in flight... Jul 11 15:22:06 georgem: those patches don't apply because the file journald-server.c does not exist. systemd v189 is checked out at 38a60d7112d33ffd596b23e8df53d75a7c09e71b Jul 11 15:27:50 the VCC pin on the seria header J1, is it 5V or 3.3? Jul 11 15:28:07 measure and find out Jul 11 15:28:24 hi all Jul 11 15:29:52 OWayne: yeah... there have been a lot of changes to journald in the last year. Newest version of angstrom should (you may want to verify first) have a version of systemd with all of those changes in it. Alternatively you could try switching to busybox init Jul 11 15:30:57 any one have tryed to use beaglebone black for some 3d on real time? Jul 11 15:31:20 ray02, it's hard since the gpu driver is not ready yet Jul 11 15:31:42 panto: he didn't ask if anyone had succeeded Jul 11 15:31:47 eheh Jul 11 15:32:31 yeah it was implied Jul 11 15:32:34 :) Jul 11 15:32:53 and around here trolls are implied too Jul 11 15:33:11 * KotH crawls out under his bridge Jul 11 15:33:49 * dm8tbr throws KotH a red chocolate flavoured herring Jul 11 15:34:03 bleh! Jul 11 15:34:28 * KotH throws dafodils at dm8tbr Jul 11 15:34:34 daffodils* Jul 11 15:35:29 so this project it's not working http://beagleboard.org/project/Irrlicht/ Jul 11 15:35:30 ? Jul 11 15:36:01 the name fits very well Jul 11 15:36:22 beagleboard != beaglebone Jul 11 15:36:47 * SpeedEvil is reminded by KotH's comment of https://www.youtube.com/watch?v=fhzpipafDTI - @1:08 Jul 11 15:37:54 hi alan_o Jul 11 15:38:00 hoi alan_o Jul 11 15:38:06 hey guys Jul 11 15:38:16 what's new around #beagle-land? Jul 11 15:38:29 trolls and n00bs Jul 11 15:38:37 is there any difference in the optargs usage when I boot from SD or eMMC? Jul 11 15:38:38 oh. wait, these are old things Jul 11 15:49:07 georgem: I have stuck at denzil for now, but I wonder if I could grab systemd from dylan and try that. Thanks for your efforts, much appreciated Jul 11 15:50:41 dylan? bob? Jul 11 15:51:21 mru, i would expect him to be saner than to have anything to do with lennartd Jul 11 15:52:17 he must have written 'everything is broken' for a reason Jul 11 15:59:06 would anyone bother to analize this for me and guess why my SPI ports are not being enabled? http://pastebin.com/WJmCWrAv Jul 11 15:59:19 they work when I boot from SD, but not from eMMC Jul 11 16:11:35 failed to load firmware 'BB-SPI0-ENABLE-00A0.dtbo' Jul 11 16:12:13 is the firmware in your SD filesystem and not on the eMMC Jul 11 16:14:51 In the BeagleBone kernel, cape Device Tree fragments are located in firmware/capes. Each cape is represented by a single DTS (Device Tree Source) fragment file. At kernel build time, these fragments are compiled by the Device Tree Compiler into dtbo files (Device Tree Blob Object). At install time, these dtbo objects are copied to /lib/firmware. Jul 11 16:17:06 gui: can you ls /lib/firmware Jul 11 16:18:03 jsarman, my dtbo files are there Jul 11 16:18:23 ok just checking that first Jul 11 16:18:34 BB-SPI0-ENABLE-00A0.dtbo Jul 11 16:18:37 BB-SPI1-ENABLE-00A0.dtbo Jul 11 16:19:13 the eMMC is an exact image of the SD card Jul 11 16:19:21 on the eMMC /lib/firmware and sd's /lib/firmware Jul 11 16:19:56 let me mount just to make sure Jul 11 16:23:22 gui: Im just scanning http://elinux.org/Capemgr Jul 11 16:25:14 is there any pastebin-like page that compare files? Jul 11 16:26:49 is there a temp sensor in the BBB core? I was wondering about it, because my beaglebone gets really hot Jul 11 16:27:33 jsarman, I just checked, the lists of files are identical Jul 11 16:28:06 http://hipstercircuits.com/enable-spi-with-device-tree-on-beaglebone-black-copy-paste/ Jul 11 16:28:14 maybe that'll help Jul 11 16:28:36 I followed that tutorial, even left some comments (see Guilherme at the end, it's me) Jul 11 16:28:43 weren't you screwing with the hdmi setting in the bootloader last night Jul 11 16:29:04 there are a few mistakes in that .dts example though Jul 11 16:29:51 no, yesterday I was screwing on how to make an img from the SD and copy to the eMMC :P Jul 11 16:31:04 i am searching a way to install a windows on beaglebone black.... VMWare or sth. like that? Jul 11 16:31:11 no Jul 11 16:31:39 but is possible for raspberry pi Jul 11 16:31:42 is there any Windows 7 Embedded verion for arm? Jul 11 16:31:45 version Jul 11 16:31:52 ok well you should keep posting on that tutorial. Good Luck Jul 11 16:31:57 gui i have but ... Jul 11 16:32:15 there is WinCE Jul 11 16:32:36 * mranostay winces Jul 11 16:32:58 thanks jsarman Jul 11 16:32:58 * LetoThe2nd winds mranostay up Jul 11 16:33:16 no i wanted win xp or i was satisfied with the latest PC Ubuntu Version. do you have an image? Jul 11 16:33:31 is there an internal temperatur sensor, which one can read? Did you guys ever worried about your temperatur? Jul 11 16:34:01 i saw a motion detector for raspberry pi on ebay... but Jul 11 16:34:26 Hank: once I had a high fever Jul 11 16:34:30 my mom was worried Jul 11 16:34:34 lol Jul 11 16:34:49 win 7 could be run on a raspberry pi with VMWare . Can winxp be run on a beaglebone board? Jul 11 16:34:50 just once? you're a healthy bou Jul 11 16:34:51 boy Jul 11 16:35:08 Bonobone: XP cannot run on Beaglebone Jul 11 16:35:13 Bonobone: there is no vmware for arm. Jul 11 16:35:15 nor on raspberry pi Jul 11 16:35:19 neither on the raspi Jul 11 16:35:51 you would only want to run win 7 on VMware on a 1Gh proc to say you did it cause if its for a product then you are doing it wrong Jul 11 16:36:00 you can do weird stuff like qemu-x86, but that has the performance of ice cold honey Jul 11 16:36:17 dm8tbr: nah, the honey is considerably faster.. Jul 11 16:36:35 LetoThe2nd: at 0K, I doubt ;) Jul 11 16:36:54 Hank: there seems to be a bandgap on the AM335x Jul 11 16:36:55 dm8tbr: hehe Jul 11 16:36:57 please elaborate on your reasoning as why you would want to do that other than to flex your ego Jul 11 16:37:00 at least the TRM mentions one Jul 11 16:37:11 well, enough of BBBs for a while Jul 11 16:37:16 no idea if there is driver support Jul 11 16:37:20 * gui_ is going to practice some soldering skills Jul 11 16:37:31 see ya o/ Jul 11 16:37:37 did you build your serial cable Jul 11 16:37:42 gui_: soldersmoke, don't breathe ;) Jul 11 16:37:47 but i saw it on youtube how to run a windows.... on raspberry... a little bit slower than beagel Jul 11 16:37:50 with "vcgencmd measure_temp" on RPi it's pretty easy to read the temp. Something like that for the BBB would be nice, but couldnt figure out yet, if there is a sensor at all? Jul 11 16:37:51 beagle Jul 11 16:38:10 bonobone_: _why_ would you want that? Jul 11 16:38:11 bonobone_: you probably saw a video showing a vnc clinet. Jul 11 16:38:25 please tell me the reason Jul 11 16:38:30 bonobone_: which is indeed super groundbreaking technology and totally unheard of Jul 11 16:38:34 *SCNR* Jul 11 16:38:40 I love MS fanboy reasonings Jul 11 16:38:55 LetoThe2nd: SHHHH, don't leak the sekrit reasonings! Jul 11 16:39:12 i wanted to use a sound card usb cause i have no hdmi sound on the beagle now.... possible with ubuntu? Jul 11 16:39:19 dm8tbr: thanks, but i'm not interested in your sekrets. Jul 11 16:39:27 more likely than your idea Jul 11 16:39:35 may just work Jul 11 16:39:37 may not Jul 11 16:39:40 Hank: read what I wrote Jul 11 16:39:57 bonobone_: your statement doesn't quite make sense Jul 11 16:39:59 bonobone: yes Jul 11 16:40:02 yes thanks av500 I am already looking it up Jul 11 16:40:08 but you would be more likely to write a custom kernel driver for it than to get win7 on it then find a driver for it Jul 11 16:40:11 9.3.9 bandgap_ctrl Register (offset = 448h) [reset = 0h] Jul 11 16:40:23 usb sound cards work fine Jul 11 16:40:30 as far as USB can ever work fine Jul 11 16:40:40 well better than on the rpi Jul 11 16:41:14 go google make menuconfig Jul 11 16:41:22 * LetoThe2nd sends some trollfood for bonobone_ to berlin and heads off. Jul 11 16:42:19 I wondered if my terminal background would go red if someone asked if win 7 could be booted Jul 11 16:42:27 * jsarman is sad it didn't Jul 11 16:43:11 haha :D Jul 11 16:44:47 I was bored eariler and was going to joking ask the win 7 ? but patience won out Jul 11 16:48:20 I found the page about the band gap register in the TI ref manual, but dont know how to read from that register. Any hints? Jul 11 16:49:09 Hank, since there's no driver for it yet, I wouldn't try to do anything with it Jul 11 16:49:24 then why not write a driver? Jul 11 16:49:32 can't be that hard Jul 11 16:49:55 KotH, I have a hunch that not being a driver yet, might mean there's something complicated there Jul 11 16:50:08 ya I think that would be a project in itself. Jul 11 16:50:36 panto: i doubt it. the lmdriver framework didnt seem that complicated when i had a look at it Jul 11 16:50:45 panto: i'd rather guess that nobody had a need for it yet Jul 11 16:51:01 * panto shrugs Jul 11 16:51:04 go for it then Jul 11 16:51:16 send a bbb this way and i might do it :) Jul 11 16:52:13 you can't do it in 15 minutes, I doubt that Jul 11 16:52:20 bandgap, is that something like a transistor that changes its behavior dependant on the temp? Is that done similar in the Rpi? Jul 11 16:53:01 Hank: bandgap is the name of the thing that gets probed by using a transistor :) Jul 11 16:53:18 Hank: the bandgap is the gap between the valence and the conducting bands Jul 11 16:53:49 Hank: and a bandgap circuit is a voltage reference based on this band difference Jul 11 16:54:05 Hank: this voltage is sensitive to temperature, thus it can be used to measure the temperature Jul 11 16:54:22 and the bandgap that one can access with the Reg is made for this applic measuring the temp or are there other needs for it? Jul 11 16:54:53 i assume it's a bandgap circuit with an ADC Jul 11 16:54:59 and you read out that ADC Jul 11 16:56:05 http://en.wikipedia.org/wiki/Bandgap_voltage_reference Jul 11 16:57:15 the data sheet is saying something of "Temperature data from ADC. To be used when end of conversion (EOCZ) is 0." that's interesting. I hope I find time to dig into it, but not sure how difficult it will be to do it Jul 11 17:01:32 picture of Rpi: http://hackaday.com/2012/06/23/checking-out-the-temperature-of-a-raspberry-pi/ Jul 11 17:02:06 a thermal picture of the BBB would result in read ICs all over the board Jul 11 17:02:20 The battery input for the TPS65217C has a TS input, but Im not sure if you can get the reading Jul 11 17:02:42 on the BBB its TP7 Jul 11 17:03:30 but you would have to add the actual sensor so probably just as easy to just add a 1-wire, i2c or spi sensor and be done with it Jul 11 17:05:20 Hank: what is your goal? preventing the cpu on the bbb from overheating? Jul 11 17:06:04 no I just love to play with it and learn something new. Jul 11 17:06:16 so ka Jul 11 17:06:20 then hack on! :-) Jul 11 17:07:27 was wondering why it get's so hot, when I use the CPU at a 100% :) Jul 11 17:07:55 that's information cooking... Jul 11 17:10:47 you should try reading the dtemp reg in the TSC_ADC if you are in hacking mode Jul 11 17:11:06 that sounds worth a shot at least Jul 11 17:41:11 here's an interesting thing: I'm connecting an atmega328 ttl pins to bbb's uart0. i'm shifting 5v to 3.3v with two simple resistors and the bbb receives just fine. however, connecting directly the 3.3v (tx) ->5v (rx) line powers down the atmega328 (arduino) (!).. this is kind of weird Jul 11 17:51:50 do you have a shared ground between them c10ud Jul 11 17:52:20 yes Jul 11 17:52:28 why don' Jul 11 17:52:32 http://img.gawkerassets.com/img/18tjbjljfr4w6jpg/ku-xlarge.jpg Jul 11 17:52:38 t you just run the atmega328 with 3.3 v Jul 11 17:52:54 This says the bone can run windows. Jul 11 17:52:59 A quick google says no. Jul 11 17:53:03 because i need the outputs at 5v for some other components Jul 11 17:53:30 anyway, i tried with another arduino (bigger model) and it worked.. that's why I'm thinking I'm missing something.. Jul 11 17:53:59 should work Jul 11 17:55:22 yep, weird..and it only happens when you try sending data (bbb->atmega)..simply connecting won't do harm Jul 11 17:56:32 clOud you must have a wiring issue, like an output to an output, which is causeing havoc when the line is trying to be both a 1 and a 0, and the Ti chip is winning. Jul 11 17:57:39 make sure the Arduino RX pin is properly being set to input. Preferably with oscope and debugger. Jul 11 17:57:39 <_av500_> Willdude123: WindowsCE Jul 11 17:57:41 <_av500_> yes Jul 11 17:57:46 <_av500_> Windows XP,7,8 Jul 11 17:57:47 <_av500_> no Jul 11 17:59:21 I would test it by hitting a breakpoint in the ard code then just changing the value in the Output reg. If the pin voltage changes with the reg change then for some reason the port is misconfigured Jul 11 17:59:59 I've been down that road before :) Jul 11 18:00:03 jsarman, I'm using the default ttl pins, they should be auto configured (I have an ftdi adapter that is wired to the same pin) Jul 11 18:00:13 but i'll double check Jul 11 18:00:23 <_av500_> http://www.usatoday.com/story/news/world/2013/07/11/russia-spies-nsa-typewriters-documents-computers/2508751/ Jul 11 18:00:27 yeah Im not disagreeing just engineering Jul 11 18:00:43 that's why I said I'll double check, I know the pain Jul 11 18:00:44 :) Jul 11 18:04:45 Yeah I had this issue a few time in the past with msp430's, now I use a 20mA reg for the 430, because instead of the IO pin getting damaged the msp430 just browns out and resets. That way I know I am doing something wrong. Jul 11 18:17:31 interesting way to deal with it jsarman Jul 11 18:17:47 which chip is that ? the 20mA regulator? Jul 11 18:41:33 they make alot of the micropower regulators Jul 11 18:44:32 for example: I didn't use this one but similar Jul 11 18:44:36 http://cds.linear.com/docs/en/design-note/dn314f.pdf Jul 11 18:44:52 80V input 5V @ 50mA Jul 11 19:00:17 The trivial way. Jul 11 19:00:30 You place a x ohm resistor in the inptu of the regulator Jul 11 19:00:55 There are of course better solutions, yes. Jul 11 19:01:01 But that one is generally fine Jul 11 19:16:50 anyone running unbuntu? Jul 11 19:17:03 want some real life opinions on OS Jul 11 19:19:02 <_Sy_> hello Jul 11 19:19:06 Aye, I too would like to know what operating systems people have the most joy with. Jul 11 19:19:24 Having real issues getting the WiFi dongle i have working with Angstrom Jul 11 19:19:26 i am. psuedo PITA to install. to interact with the board you need the right node.ks modules. It works fairly well for running an OS (ssh, webseserver etc). I But i probably wouldn't do any GPIO development without angstrom Jul 11 19:19:55 Welp, Angstrom it is for me then! Jul 11 19:20:14 but, that is just me. Jul 11 19:20:55 <_Sy_> Been rebuilding systems all night...got to setting up drive mapping in fstab and have screwed it up.... Jul 11 19:20:58 Just need to get this damn WiFi driver working ;) Jul 11 19:21:20 <_Sy_> can someone tell me whats wrong with this and how should it read? " Jul 11 19:21:20 <_Sy_> /dev/sda /mnt/usbstick auto rw,defaults 0 0 Jul 11 19:21:20 <_Sy_> " Jul 11 19:21:28 I'd ask for help, but I'm in the middle of splatting Angstrom back!! Jul 11 19:22:13 _Sy_: man fstab Jul 11 19:22:58 _Sy_: the old unix config files are all described in their respective manpages Jul 11 19:23:32 <_Sy_> What I've done looks ok according to the site I'm looking at on fstab, but now it won't boot Jul 11 19:23:51 what error do you get? Jul 11 19:23:58 and what was the line before? Jul 11 19:24:01 <_Sy_> None it won't start Jul 11 19:24:18 have you a serial console connected? Jul 11 19:24:31 <_Sy_> no Jul 11 19:24:34 well Jul 11 19:24:39 that's your problem then Jul 11 19:24:43 you dont see the boot messages Jul 11 19:24:58 connect a serial cable and have a look at the boot messages Jul 11 19:25:03 they will tell you what's wrong Jul 11 19:25:03 <_Sy_> I'll make one up tomorrow....bugger, forgot to do it today Jul 11 19:25:24 never start hacking with an embedded linux system w/o having a serial console running Jul 11 19:25:44 ie, you should have gotten one weeks ago ;) Jul 11 19:26:00 <_Sy_> kicking myself this is the 3rd time I've set these up...have noted everything down in evernote, except the fstab details. Jul 11 19:27:31 tststs Jul 11 19:27:56 real men have an svn/git/whatever repo where they store all their config files and build scripts Jul 11 19:28:04 so they can go back when something went wrong Jul 11 19:29:06 <_Sy_> I thought I had created a backup image, but as it turns out I didn't do it correctly, is there a FAQ or site with instructions on how to backup eMMC once I'm done? Jul 11 19:31:03 oh noes Jul 11 20:34:54 <_Sy_> Just ordered one of these.... should help... http://www.amazon.co.uk/gp/product/B0055ELU46/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 Jul 11 20:44:28 sy is so helpful, keeping us up to date Jul 11 20:44:37 lulz Jul 11 21:01:31 speaking of ftdi, anyone have experience with the usb-to-ttl/rs232/rs485 boards claiming ftdi chips.. worth my money? Jul 11 21:26:58 http://www.ebay.com/itm/Newlink-QUAD-USB-2-0-Serial-RS232-Adapter-4-Port-/200573327284?pt=UK_Computing_Parallel_Serial_PS_2&hash=item2eb31a17b4 Jul 11 21:27:04 I wonder if anyone falls for that... Jul 11 21:30:19 apparantly 24 have Jul 11 21:39:46 Will the uart baudrate go down to 50 onnthe black? Jul 11 21:40:50 vaizki_: What's wrong with that? Jul 11 21:41:11 vaizki_: I'd imagine it uses an FT4232H or equivalent Jul 11 21:41:32 vaizki_: Ohhhh. Jul 11 21:41:35 vaizki_: Ouch. Jul 11 21:41:46 Nevermind. Jul 11 21:41:58 better use gold-plated FT4232Hs for that price :/ Jul 11 21:42:52 make that solid gold. Jul 11 21:43:11 MicroSDs are worth more than their weight in gold. Jul 11 22:03:02 Hi Jul 11 22:03:40 Rush_4ever: hello! do you have a FTDI cable for debug serial console access? Jul 11 22:04:51 No I haven't got one, planning on getting one tho. Jul 11 22:06:42 I'm having some problems with the new kernel version, some python libraries seem to have some difficulties with this and therefore i am loooking for an angstrom version which van be flashed to eMMC which uses kernel 3.2. Jul 11 22:07:37 vaizki: do we have another client that needs serial debug? Jul 11 22:08:59 whoever is the ops for this board the motd should say please have your serial debug cable plugged in and operation before asking for help Jul 11 22:10:58 bored with a capital B Jul 11 22:11:27 python libraries have problems with your kernel version? Jul 11 22:11:45 jsarman: aaaand here's gui_! Jul 11 22:11:55 right on cue Jul 11 22:12:14 dafuq did I do? Jul 11 22:12:36 hi, btw Jul 11 22:12:44 2 minutes ago -- jsarman: whoever is the ops for this board the motd should say please have your serial debug cable plugged in and operation before asking for help Jul 11 22:12:52 just a funny coincidence Jul 11 22:12:54 and oh hi Jul 11 22:12:57 hahaha Jul 11 22:13:17 i made my own cable #nerdpride #noooot Jul 11 22:13:52 do you have a fab for making usb-serial chips? Jul 11 22:13:57 since youre here, would you mind check line 41 for me? http://pastebin.com/TUizbTjs Jul 11 22:14:10 no, it's a pure serial, RS232 Jul 11 22:14:13 level converter Jul 11 22:14:35 ah Jul 11 22:14:57 line 41 looks ok. line 42 doesn't Jul 11 22:15:00 thank you Dell, the only PC manufacture who still supply us with beautiful serial ports :) Jul 11 22:15:15 yeah, i meant 42 Jul 11 22:15:40 i'm running the BBB with ubuntu, no HDMI cable plugged, no optargs Jul 11 22:15:44 well you are loading two virtual cape definitions which conflict Jul 11 22:16:06 one or both of them are requiring exclusive use of P8.45 Jul 11 22:16:37 there are 3 capes being loaded: eMMC-2G, HDMI and HDMIN Jul 11 22:16:48 all of them are "default" capes Jul 11 22:16:50 gui: Im happier with my ftdi as I can make it go 1 mbps, built in serial is lucky if it can go 230400 Jul 11 22:17:47 if I had 9600, that'd be enough :P Jul 11 22:18:14 here's lesson since you are younger http://en.wikipedia.org/wiki/16550_UART Jul 11 22:18:48 thats ole school for me and was hi tech pre usb Jul 11 22:19:28 just cause i'm younger doesnt mean I don't know history Jul 11 22:19:36 I can't really help with cape debugging, I have never hooked up anything to the HDMI in my BBB Jul 11 22:19:50 The PyBBIO llibrary does have a problem with the PWM folder which does not exist anymore on kernel 3.8 Jul 11 22:20:10 may I tell you that I'm from a 3rd world country, and I used to learn things, somtimes, in 20+ years old equipment Jul 11 22:20:11 i figured you did just passing some along if you didnt Jul 11 22:20:20 Rush_4ever: you probably just have to modprobe a module to regain it? Jul 11 22:20:39 gui_: which country? Jul 11 22:20:42 as I was passed the punch card stories from my profs and I was like sux to be you Jul 11 22:20:43 Brazil Jul 11 22:21:00 umm ok well I don't think it's a third world country :D Jul 11 22:21:11 it's a economic up & coming powerhouse Jul 11 22:21:14 an Jul 11 22:21:20 'cuse my english Jul 11 22:21:21 well... it's not 1st, and there's no 2nd, so it has to be 3rd Jul 11 22:21:34 in America news has been talking up the billionaires in Brazil all week Jul 11 22:22:06 like the one who bought Burguer King and Heinz? Jul 11 22:22:27 i just heard them start talking about it and zoned out Jul 11 22:22:39 I didn't really stay for the story Jul 11 22:22:41 goddammit that wikipedia pic of the 16550A brings back some memories Jul 11 22:22:52 i've been living in US for 10 months and I still can't watch tv here Jul 11 22:23:01 kill(SIGTROLL) Jul 11 22:23:11 vaizki_: https://github.com/alexanderhiam/PyBBIO/issues/20 Jul 11 22:23:13 it is so so so annoying with all those stupid commercials Jul 11 22:23:23 not sure how they do it in brazil but here they talk about the upcoming story for an hour before showing it Jul 11 22:23:34 by then Im over it Jul 11 22:23:36 Rush_4ever, if you need PWM, give it a try to Adafruit BBIO Jul 11 22:24:31 Rush_4ever: sorry can't help you, I'm not an angstrom user Jul 11 22:24:49 jsarman, I remember one episode of a live policial-program which the host spent the whole program talking about some "dossie" whe'd show revealing some serious stuff. and HE DIDN'T SHOW! Jul 11 22:25:00 then again we Arch users live on the bleeding edge always, and there's often no way to go back in time :) Jul 11 22:25:06 gui: Im so glad you took the effort and built the debug cable Jul 11 22:25:17 gui_: just don't watch tv Jul 11 22:25:28 that's what I do vaizki_ Jul 11 22:25:39 vaizki: aren't you on solar and batteries Jul 11 22:25:50 not today Jul 11 22:25:50 TV would waste the watts Jul 11 22:25:53 oh Jul 11 22:25:58 I usually go to the movies, netflix or buy some movies in a certain bay Jul 11 22:26:21 boat + car ride to town, spending the night here, paying some bills etc.. going back tomorrow Jul 11 22:26:34 see my prob is I'm American and TV is what raises us Jul 11 22:27:01 luckily for me my parents got me an atari 400 and the Basic cartridge Jul 11 22:27:10 your family raised you. Jul 11 22:27:18 they tell how much TV you can watch Jul 11 22:27:26 in a direct ir indirect way Jul 11 22:27:28 jsarman was raised by an atari Jul 11 22:27:32 maybe videos of his family on tv ? Jul 11 22:27:47 raised by pitfall Jul 11 22:27:50 * jsarman loved his Atari 400 Jul 11 22:28:01 frogger parenting Jul 11 22:28:02 i've never seen an atari in front of me Jul 11 22:28:10 :/ Jul 11 22:28:18 the atari 400 is not the atari 2600 Jul 11 22:28:26 my first videogame was a N64 Jul 11 22:28:30 second a master system Jul 11 22:28:34 same here Jul 11 22:28:40 it actually had a keyboard and could be programmed Jul 11 22:28:42 and master system > anything Jul 11 22:28:53 3D goggles Jul 11 22:28:57 lightphaser Jul 11 22:29:10 http://en.wikipedia.org/wiki/File:Atari-400-Comp.jpg Jul 11 22:29:17 the name says it all... it's a MASTER system Jul 11 22:29:20 yea but Atari 400 had Frogger Jul 11 22:29:43 LOL looks like a checkout machine from the market Jul 11 22:29:51 who do you call it? Jul 11 22:29:59 how* Jul 11 22:30:01 i guess i wasnt born back then when it came out lol Jul 11 22:30:02 my parents didn't go that far got the system with basic and star raiders and thats it Jul 11 22:30:31 that keyboard.. argh Jul 11 22:30:52 oh dude in 80's was the bomb Jul 11 22:31:10 must've given some serious haptic feedback Jul 11 22:31:20 ahahhaha Jul 11 22:31:21 sorry but my vic-20 was the bomb in '81 Jul 11 22:31:39 well I was happy to be able to compute Jul 11 22:31:57 a few days ago I was wondering: if men went to moon with 256KB... I think I can make a rocket with this beaglebone Jul 11 22:31:59 of course. but I always hated those membrane keybosrds Jul 11 22:32:03 boards Jul 11 22:32:13 me too now Jul 11 22:32:17 256kb? what? Jul 11 22:32:25 back then I knew nothing else Jul 11 22:32:26 apollo flight computer didn't have 256kb? Jul 11 22:32:35 less? more? Jul 11 22:32:46 what ever... it was insignificant compared to nowadays Jul 11 22:32:58 2048*16bit words ram Jul 11 22:33:12 so basically 4k Jul 11 22:33:13 thats 32KB Jul 11 22:33:25 Kb Jul 11 22:33:25 no it's 32kb or 4kB Jul 11 22:33:31 yeah, my bad Jul 11 22:33:35 32kB ought ot be enough for anyone Jul 11 22:34:03 tell that to a digital camera Jul 11 22:34:10 well it's more than many of the MCUs have that I use Jul 11 22:34:36 Rush_4ever, have you seen that "russian photoshop from the 70's"? Jul 11 22:34:44 a 1 usd mcu would take the apollo to the moon easy Jul 11 22:34:47 http://en.wikipedia.org/wiki/Apollo_Guidance_Computer Jul 11 22:35:09 not going pretend I knew any of that but man that was engineering Jul 11 22:35:13 can we rebuild apolo using a PIC? Jul 11 22:35:35 i guess but might as well use best available Jul 11 22:36:10 PIC I skipped cause I had the HC08 with flash memory Jul 11 22:36:25 and at the time the PIC had to be UV erased Jul 11 22:37:04 which took like 30 minutes for new chip and longer the more you reprogrammed Jul 11 22:37:16 UV, what millenium was dat? Jul 11 22:37:22 90's Jul 11 22:37:23 well the AGC had it's own instruction set, a PIC32 could easily emulate it Jul 11 22:37:42 yeah dude I barely skipped that Jul 11 22:37:51 i played with some EPROM in the lab once Jul 11 22:37:59 covered with electrical tape Jul 11 22:38:02 I was first class in my EE program with flash based micros Jul 11 22:38:26 we could flash in like 2 secs Jul 11 22:38:28 or so Jul 11 22:38:50 and laughed at the older students who didn't want to learn the new stuff Jul 11 22:39:20 that's why I never wanted to learn history Jul 11 22:39:21 then we got msp430's later on so I never touched pics Jul 11 22:39:47 not knocking them just didn't go down that road Jul 11 22:40:02 so I guess you didn't play with arduinos either Jul 11 22:40:13 "too easy for me" Jul 11 22:40:15 I've never used a PIC either Jul 11 22:40:40 not really but I like em cause I can drive 10 minutes from my house and buy one Jul 11 22:40:48 at radio shack Jul 11 22:41:02 the cyclling team ? Jul 11 22:41:14 in Brazil I need to ride 1h30 to get either one Jul 11 22:41:23 so I think that is awesome, but having the beagle XM I didn't need the arduino Jul 11 22:42:19 I order everything online instead of going shopping Jul 11 22:42:25 jsarman: got a bbb by chance? Jul 11 22:42:41 coming either in the morning or Saturday Jul 11 22:42:45 ah Jul 11 22:42:59 works very nicely Jul 11 22:43:04 Ti sent me email late, I thought I was first Jul 11 22:43:16 then realized Im late to the party Jul 11 22:43:19 not so nicely i'd say Jul 11 22:43:22 :( Jul 11 22:43:28 gui_: why? Jul 11 22:43:43 gui I think you are trying to hard Jul 11 22:43:44 I have a great setup on my SD card Jul 11 22:43:52 I have same problem Jul 11 22:44:01 but when I copy 1:1 to the eMMC, some weird stuff happens Jul 11 22:44:01 mine is running slackware quite nicely Jul 11 22:44:07 I can figure out every way to make something not work Jul 11 22:44:28 after Im done I know pretty much everything about it Jul 11 22:44:35 I had a teacher, quite funny Jul 11 22:45:01 gui_: but now you have the cable so you know what's wrong.. Jul 11 22:45:04 he'd tell us many times about the novice students who used to fail the led-blink first class Jul 11 22:45:05 ooh llvm 3.3.. this should be fun Jul 11 22:45:06 cause I had to learn the dirty details Jul 11 22:45:38 I did those quite well Jul 11 22:45:41 he'd say that some students insisted in coding something where you push the LED and the button lights up Jul 11 22:46:27 hmm.. apollo used LOL memory for ROM. Short for Little Old Lady memory Jul 11 22:46:39 I get stuck on problems like setting up bootloader pins in situations where I built my own board and added second sd slot on mmc3 which was 1.8V only Jul 11 22:46:47 school... such a long time ago.... Jul 11 22:46:47 build all circuits correct Jul 11 22:46:49 it was hand-woven magnetic core ROM done by little old ladies :) Jul 11 22:46:51 vaizki_, i'm still noob at it. I can see there are problems, but I don't know how to solve them yet Jul 11 22:46:59 then set clk line to output and mode to mmc Jul 11 22:47:24 spend 8 hours going through kernel code trying to figure out why my clock aint clocking Jul 11 22:47:41 only to finally try to set the output clock to input Jul 11 22:47:43 mmc... bah miss the old casette tape days Jul 11 22:47:46 and it work Jul 11 22:47:55 that kinda wrong Jul 11 22:48:07 I don't miss casette tapes Jul 11 22:48:10 vaizki_, it's like computers in Portugal. They don't have memory... just a vague remembrance Jul 11 22:48:21 vaizki_: aww. they were fun Jul 11 22:48:23 huh? Jul 11 22:49:03 i actually had a vinyl lp with data on it once Jul 11 22:49:04 cassetes were fun when you were hi-speed copying them and it would play in a higher ptch Jul 11 22:49:05 pitch Jul 11 22:49:18 flexible thin sheet of vinyl Jul 11 22:49:22 oh my atari 400 had a cassette and it never worked Jul 11 22:50:04 http://upload.wikimedia.org/wikipedia/commons/d/da/KL_CoreMemory.jpg Jul 11 22:50:08 that is.. art Jul 11 22:50:29 1024 bits of real core Jul 11 22:50:30 is that made in a sewing machine? Jul 11 22:50:38 so I am fortunate enogh to get invited to an IEEE meeting in Vale where the elite go to sit in a basement to talk circuits Jul 11 22:50:56 gettin the rpm right to load it was the hardest part Jul 11 22:51:09 I meet Allan Alcorn who created PONG and get to talking about my cassette that never worked Jul 11 22:51:19 he was part of that team to build it Jul 11 22:51:22 nice Jul 11 22:51:37 he was like you had to adjust the heads Jul 11 22:51:49 I said I was 6 years old Jul 11 22:51:57 then you tilt your head 15 degrees? Jul 11 22:52:15 but was so cool to hang out with him Jul 11 22:52:25 did you play pong with him? Jul 11 22:52:45 telling me when they first built pong and put it in a bar or something Jul 11 22:52:47 not fun. he knows cheatcodes Jul 11 22:53:06 pong trainer mode Jul 11 22:53:07 they told him to come get it the next week cause it was broke Jul 11 22:53:11 pong had no cheats Jul 11 22:53:18 o'rly Jul 11 22:53:25 it broke because the machine was full of quarters Jul 11 22:53:32 hahaha Jul 11 22:53:43 jsarman speaks the truth Jul 11 22:53:54 all hail the sarman Jul 11 22:54:06 saruman? Jul 11 22:54:12 shh Jul 11 22:54:17 yeah well my wife telling me to get off the computer Jul 11 22:54:17 sorry Jul 11 22:54:34 tell her to buy one for herself and join us Jul 11 22:54:40 so enough fun for me tonight Jul 11 22:54:51 she dont hack Jul 11 22:55:18 anyways talk at yall later Jul 11 22:55:29 see ya! Jul 11 22:55:33 i have to go home too Jul 11 22:56:14 I need to sleep but I have a powerpoint to make :P Jul 11 22:56:20 and it's 2am Jul 11 22:56:23 pfff Jul 11 22:56:42 you have plenty of time to redo everything in a better layout Jul 11 22:57:06 jk Jul 11 22:57:15 gotta go. ciao! Jul 11 23:04:47 can anybody explain to me the build process to build mmc drivers into your kernel on the BBB? Jul 11 23:08:58 just use menuconfig? Jul 11 23:57:21 uh - aren't mmc drivers already there? Jul 12 00:46:04 emeb: hi Jul 12 01:17:17 mrpackethead: hi Jul 12 01:22:26 emeb_mac: almost there! Jul 12 01:22:34 hihi Jul 12 01:22:45 mrpackethead: where? Jul 12 01:23:00 almost got a useful working somethign off the back fo the bcc Jul 12 01:23:17 mrpackethead: Aha! Bits coming out? Jul 12 01:23:23 yup, bits coming out Jul 12 01:23:29 sensibly, predicatbly Jul 12 01:23:38 SPI from the uP to th FPGA Jul 12 01:23:40 So these FPGA things aren't just a figment after all... Jul 12 01:23:41 and then DMX out Jul 12 01:24:24 Nice. DMX is a serial protocol sort of like MIDI, no? Jul 12 01:24:46 yes they are a figment of your imagination! Jul 12 01:24:54 not really like midi Jul 12 01:25:07 its 250k signalling over RS485 Jul 12 01:25:17 512 bytes per frame Jul 12 01:25:27 with some werid breaks and timing Jul 12 01:26:07 aha. Jul 12 01:26:42 just saw the DIN connectors and the IN/OUT/THRU terminology and immediately leapt to MIDI Jul 12 01:27:00 really looking forward to Spartan 6 Jul 12 01:27:08 ds2: a consensual figment is as good as reality. Jul 12 01:27:41 mrpackethead: yeah - when I get some time to push that forward... Jul 12 01:27:51 things are kind of busy here for a few weeks tho Jul 12 01:29:14 i'm busy till the end of the year Jul 12 01:29:18 i'm not hurrying you up Jul 12 01:29:19 :-) Jul 12 01:30:23 emeb_mac: any plans to make a microsemi version with analog stuff? Jul 12 01:31:34 it never ceases to baffle me how complicated they managed to make DMX and still keep it unidirectional and without any form of error detection not to mention correction Jul 12 01:31:37 ds2: Microsemi has some interesting stuff. I've looked at it but never worked with them. Jul 12 01:32:47 ka6sox: ping Jul 12 01:32:48 vaizki_: dmx is remarkably simple Jul 12 01:33:00 ds2: you have a particular family from them you're interested in? Jul 12 01:33:34 we can implement a receiver with about 100 lines of assembly on a pic16 Jul 12 01:34:20 mrpackethead: cool - I'm hoping to get some time in a few weeks. Jul 12 01:35:06 emeb_mac: maybe we should get smarter with the 6, and run them as finished Jul 12 01:35:42 mrpackethead: not sure I understand what you meant by that. Jul 12 01:36:01 make up 50, completed Jul 12 01:36:09 rather than jsut pcbs Jul 12 01:36:47 mrpackethead: well it's easy for MCUs and the like, but not for just standard UARTs.. I don't know why they wanted to make the break-separation for packets, maybe for added robustness etc.. but why not put in CRCs for example? even as optional! :) Jul 12 01:37:18 vaizki_: i use the uart on the uP Jul 12 01:37:48 hmh. ok... well I believe you since I haven't done DMX work myself, just studied it for a pyro app Jul 12 01:38:04 dmx / pryo.. thats a big no-no Jul 12 01:38:13 yes, and I was wondering why Jul 12 01:38:15 you'd get laughed out of the show if you did that in the pro word Jul 12 01:38:17 until I read the spec Jul 12 01:38:29 now it's crystal clear to me ;) Jul 12 01:38:36 you can do it Jul 12 01:38:42 but you need to have another layer of lockouts Jul 12 01:38:56 mrpackethead: aha - fully assembled boards ready to plug & plat. Jul 12 01:39:03 s/plat/play/ Jul 12 01:39:03 plug and plat Jul 12 01:39:11 yes, plat sounds good Jul 12 01:39:32 I'd imagine you could find a few folks interested in buying those. Jul 12 01:39:43 yup, in deed Jul 12 01:40:31 I'd want to do a few protos to get confidence in the design, but a small prod. run would be fine with me. Jul 12 01:40:48 don't tempt me with FPGAs Jul 12 01:41:05 I do not need new toys to explore Jul 12 01:41:36 emeb_mac: yeah... one of the one with teh analog stuff. I think only one family has that Jul 12 01:41:54 ds2: looking... Jul 12 01:41:57 the thing with FPGAs is I can usually find hard logic for what I want Jul 12 01:42:10 it is always the analog stuff that has me stimmied Jul 12 01:43:08 ds2: http://www.microsemi.com/fpga-soc/fpga/fusion Jul 12 01:44:12 SmartFusion Jul 12 01:44:51 I never work with stuff that needs to run so fast as to require a FPGA... Jul 12 01:44:58 either that or the smartfusion (smart adds a M3 core) Jul 12 01:45:01 doesn't stop me from wanting to learn them Jul 12 01:45:33 12bit 600ksps adcs.. not bad Jul 12 01:46:43 hmm I might have one of those Jul 12 01:46:53 I have Pigeon Point ATCA stuff :) Jul 12 01:47:34 anyway, couple of hours of sleep needed Jul 12 01:48:29 ds2: I guess I don't see the big deal - Fusion is just an FPGA + ADC and their "analog quad" blocks are some fairly simple I/O structures with thresholding and signal conditioning. Jul 12 01:50:44 ds2: and considering that the smallest Fusion parts cost > $90 in small qty, I don't feel any urge to pursue those. Jul 12 01:54:27 'k Jul 12 01:59:18 ds2: have you gone any further with the newer PSoC parts? Those look like a better deal. Jul 12 02:24:07 emeb_mac: I have the right EVB now Jul 12 02:24:49 the limitation is the analog on the PSoCs are slow (<1MHz) Jul 12 02:32:17 ds2: yes - I've also noted narrow BW on the PSoC stuff. Jul 12 02:32:56 one of the reasons I didn't pursue it much past the first few projects. Jul 12 02:34:21 how about cypress psocs? they have cortex m3 stuff with pretty good analog side? Jul 12 02:35:52 M3, M0, or 8051 Jul 12 02:36:04 well seems like they go only to 1Msps as well Jul 12 02:42:19 cypress PSoC is what we were talking about. Jul 12 02:54:46 ah. sorry.. I dropped off and lost my backscroll :) **** ENDING LOGGING AT Fri Jul 12 02:59:58 2013
