**** BEGIN LOGGING AT Tue Jul 09 03:00:00 2013 Jul 09 03:13:15 can somebody help me out with the a question to the uEnv.txt for the BBB? Jul 09 03:14:13 I need to add this line: optargs=video=HDMI-A-1:640x480@60 Jul 09 03:14:56 but there is already written this optargs= expansion_args=setenv expansion ip=${ip_method} Jul 09 03:16:32 I tried a few ways how to add it, but either the board does not boot any longer or doesn't change the resolution as expected. Jul 09 03:18:55 This is my uEnv.txt http://textsnip.com/14rosf Jul 09 03:25:25 I want to create a webserver in beaglebone its my first time and would like to have some advice. is there anyone hre? Jul 09 03:32:39 look at nodejs and expressjs Jul 09 03:32:55 expressjs has an easy way to server pages up Jul 09 03:32:59 lots of examples Jul 09 03:33:46 3 Jul 09 03:36:56 optargs= expansion_args=setenv expansion ip=${ip_method} this is the line I need to modify. But I dont even know what optargs is Jul 09 03:39:14 It has to do with command line execution. Can I use it multiple times? Jul 09 03:52:07 is anyone else having trouble connecting to cloud 9? Jul 09 03:54:11 anyone there? Jul 09 03:56:02 derekpdx: no Jul 09 03:58:10 we just dont have an answer :) Jul 09 03:59:02 it depends on if we are out of the good stuff or not Jul 09 03:59:08 4.71 min peak voltage is bad on a car battery right? :) Jul 09 03:59:27 min peak voltage? Jul 09 03:59:30 what does that mean? Jul 09 03:59:42 peak when starter is running? Jul 09 03:59:49 and is this a 6V system? Jul 09 04:00:59 I did not notice that line before in my uEnv: #Video: Uncomment to override: #kms_force_mode=video=HDMI-A-1:1024x768@60 Jul 09 04:00:59 ds2: when you start the car the voltage drops to 4.7v :) Jul 09 04:01:16 now it is 11v on star Jul 09 04:01:19 *start Jul 09 04:01:39 you might have a weak cell Jul 09 04:01:59 do a specific gravity check on each cell Jul 09 04:02:08 yeah anyway i've been putting off a recall notice anyway Jul 09 04:02:26 how old is the battery? Jul 09 04:02:51 old as the car Jul 09 04:02:54 5 years Jul 09 04:03:03 how old is the car? Jul 09 04:03:11 some batteries need to be refilled with water Jul 09 04:03:46 oh Jul 09 04:03:50 and car still starts? Jul 09 04:03:59 wonder if you have a bad alternator Jul 09 04:04:21 ds2: barely got it started and let it charge for a half hour Jul 09 04:04:26 and it starts fine now Jul 09 04:04:38 Oh heh Jul 09 04:04:52 so alternator not likely? Jul 09 04:05:08 * mranostay wishes he had a bike rack on the car Jul 09 04:05:33 no service locations near the airport Jul 09 04:06:21 donno... 11V is really really low Jul 09 04:06:27 ds2: so bad alternator it wouldn't even charge correct? Jul 09 04:06:29 it is considered almost dead Jul 09 04:06:42 mranostay: it could be a weak charge Jul 09 04:06:53 11V after half an hour charging? Jul 09 04:07:12 Franklin: on startup yes Jul 09 04:07:14 did you measure with how many volts it got charged? Jul 09 04:07:25 14v Jul 09 04:07:42 Oh 14V when running? Jul 09 04:07:46 then alt. is probally fine Jul 09 04:08:04 charge it off the car overnight then do a carbon pile test on it Jul 09 04:08:08 if that fails, replace it. Jul 09 04:09:41 i hate cars :) Jul 09 04:10:01 i hate trolls Jul 09 04:10:17 * mrpackethead is a hobbit Jul 09 04:10:19 cars are fun Jul 09 04:10:26 less temperental then beagleboards ;) Jul 09 04:10:34 I never measured the startup voltage, but 11V at starting could be possible. Many cars got weaker lights at startup, so I guess a voltage drop of 1 or 2 V shouldnt be a problem. But 4.7V sounds bad. :D Jul 09 04:10:34 never liked driving Jul 09 04:10:42 horrah, for TI Jul 09 04:10:46 they win 1st place Jul 09 04:10:57 Franklin: why i'm surprised it even started Jul 09 04:11:13 in the catagory. " how to put information in the most obscure place Jul 09 04:12:34 yea I am still working on my damn uEnv Jul 09 04:12:56 ds2: the thing it is impossible to leave the lights on my car. so battery is likely going bad :) Jul 09 04:13:16 mraonstay: you don't have LED lights? :D Jul 09 04:14:10 ds2: carbon pile test? Jul 09 04:14:22 ok, heres a 74 series quiz Jul 09 04:14:35 mranostay: it is a box used by mechanics to put a load on a battery to evaluate them Jul 09 04:14:36 maybe it is one of those that need maintenance, so you just need to fill up the water again. Jul 09 04:14:41 what IC, will count pulses Jul 09 04:14:47 and then reset when it gets to 4 Jul 09 04:15:07 ds2: so autozone should be able to do that? Jul 09 04:15:23 mranostay: if they are competant, yep. Jul 09 04:18:52 Did you measure the current when everything is turned off. Maybe you have leakage currents. If so, then good luck. They take forever to find. Jul 09 04:19:59 I was looking for one recently with my brother. He tried to measure the current of the battery in parallel :D Was a funny lightning :D Jul 09 04:21:06 Franklin: i'd say eff it and get rid of the car :P Jul 09 04:21:55 costs me $400 a month roughly anyway Jul 09 04:21:59 I sold mine and I am really enjoying riding my bike. :) Jul 09 04:22:22 * mranostay wishs someone would total his parked car :) Jul 09 04:23:27 mranostay: you want an insuracne payout, or to sue them Jul 09 04:23:52 well i don't want to be in the parked car :) Jul 09 04:23:56 former Jul 09 04:26:02 just $400? Jul 09 04:26:08 how much is parking fees? ;) Jul 09 04:26:08 funny, sometimes the obvsious eludes. Jul 09 04:26:38 the 74 series equiv of the old 4017 counter is a 74HC4017 Jul 09 04:26:47 hows that for obvious Jul 09 04:27:02 ds2: $125 of that Jul 09 04:27:13 i own the car outright Jul 09 04:27:17 geez Jul 09 04:27:27 thats weird is'nt it Jul 09 04:27:39 that osmeone in america actually owns the stuff they have Jul 09 04:27:51 heh i have zero debt Jul 09 04:28:08 that is an awesome position to be in Jul 09 04:28:12 reminds me of a joke. Jul 09 04:29:04 A well dressed couple where walking down the street to do some shopping when they came across a man sleeping in a doorway of a closed shop Jul 09 04:29:30 the wife said to her husband.

So you can pull parts from them for a project when you can't buy anything that large anymore. Jul 09 13:24:36 never understood why people hold on to the days of through hole Jul 09 13:24:48 its like some kind of Stockholm thing Jul 09 13:25:03 because they have still 5mm solder and a 10mm solderblade on their iron? Jul 09 13:25:19 yup Jul 09 13:25:31 And drink too much caffeine. Jul 09 13:25:42 georgem: i rather buy them new, then i have exactly the part that fits, i know it's working and spend less time debuging half broken parts Jul 09 13:25:49 and it costs less Jul 09 13:26:14 I really like using a nice chisel tip for smd work Jul 09 13:26:25 KotH: If you can get them that works great. Jul 09 13:26:45 anyone who thinks they suck at soldering just needs to use moar flux Jul 09 13:27:13 georgem: new parts usually work Jul 09 13:27:20 given that you can literally buy 1000 of just about any passive for about $2.... Jul 09 13:27:30 Russ: flux? Jul 09 13:27:41 Russ: in most situations you dont need any flux Jul 09 13:27:51 Russ: just more training in soldering :) Jul 09 13:28:08 flux is the goo of the gods Jul 09 13:28:15 it makes magic happen Jul 09 13:28:30 you dont need magic to happen, as long as you dont let the magic smoke out Jul 09 13:29:00 especially for rework, like when using hot air Jul 09 13:29:08 who let the smoke out? who!? who!? who!? who let the smoke out!? ... Jul 09 13:29:13 heh Jul 09 13:29:53 Russ: ok, there is one valid reason to use flux: when soldering BGA's by hand with a hot air gun :) Jul 09 13:30:12 KotH, I usually use paste for all my first go arounds of assembly Jul 09 13:30:35 flux gets used for reworking bridges, or if I have to remove a component, and replace it Jul 09 13:30:35 Russ: what kind of cases do you solder that you need additional flux? Jul 09 13:30:35 ;p; Jul 09 13:30:36 lol Jul 09 13:30:38 I work with a bunch of soldering gods so I usually surrender to them when I need 100+ pin IC put on or taken off Jul 09 13:30:48 * Spirilis uses flux liberally b/c he's a noob and refuses to beat his chest Jul 09 13:30:53 Russ: ah.. ok Jul 09 13:30:58 always with a canister of alcohol and qtips nearby Jul 09 13:31:04 like one time I placed a tqfp-48 in the wrong orientation Jul 09 13:31:22 hot air remove, apply flux, rotate, set it down, apply hot air Jul 09 13:31:26 georgem: taking of a big case is just a matter whether you have the right hot air gun Jul 09 13:31:39 Russ: :-) Jul 09 13:32:25 BGA parts just ruin everyone's day though :( Jul 09 13:32:35 btw, as far as paste goes, I saw a new service getting started http://www.oshstencils.com/pricing.php Jul 09 13:32:55 georgem, not really, they are actually pretty nice if you do reflow Jul 09 13:33:13 much wider pitch generally than other parts (1mm vs 0.5mm) Jul 09 13:34:02 now 0.6mm, 0.5mm bga, that's just pain Jul 09 13:34:26 Russ: They tell me they must be placed by the pick and place and x-rayed afterwards. Jul 09 13:34:37 you mean for 0.5mm? or BGA in general? Jul 09 13:34:50 BGA in general. I didn't ask specifically Jul 09 13:35:05 no, 1mm is easier to place than most smd components Jul 09 13:35:41 and either with the thin layer of flux technique, or using a proper stencil, there aren't any problems with bridging at that pitch Jul 09 13:35:53 even if you place it pretty far off, it'll correct during reflow Jul 09 13:36:44 https://www.youtube.com/watch?v=5mWHRakh5Hw Jul 09 13:38:13 damn it they were probably just trying to get out of doing it Jul 09 13:39:35 I suppose it depends if you are making 5 or 50,000 Jul 09 13:39:48 Just prototype stuff so like 1-5 Jul 09 13:40:31 We don't have a reball station or anything. Maybe we just don't have the right equipment. *shrugs* Jul 09 13:40:36 ya, then its an easy process, especially if you have stencil and reflow capabilities Jul 09 13:40:51 why reball if you are prototyping? just buy a new chip Jul 09 13:41:10 chips can be expensive : Jul 09 13:41:18 I've considered getting stuff to reball big fpgas Jul 09 13:41:21 Russ: some parts have long lead times Jul 09 13:41:31 the preforms look pretty cool Jul 09 13:41:33 well yes, if you have a $5k fpga, you might want to consider spending a little extra on assembly Jul 09 13:41:42 georgem, buy extra :) Jul 09 13:42:24 Russ: Its a prototype. We'd be grabbing it from something else. Example eMMC chips Jul 09 13:43:05 We're still trying to get samples. Maybe that will pan out one of these days Jul 09 13:43:10 Russ: BGAs are not necessarily self aligning anymore with the lead free solders Jul 09 13:43:21 Russ: surface tension of current lead free solders is just too low Jul 09 13:44:12 all my pbfree stuff aligned just fine Jul 09 13:44:34 georgem: you dont need to x-ray BGA soldering, unless the guy who does the soldering doesnt know his oven Jul 09 13:45:31 Russ: 1mm 100-1000pin? i guess? Jul 09 13:45:59 1mm 784 and 0.8mm ddr2 Jul 09 13:46:33 hmm... Jul 09 13:46:34 even 0402's (EIA) Jul 09 13:46:38 * KotH takes notes Jul 09 13:46:50 0402s are easy :) Jul 09 13:46:55 we even solder them by hand Jul 09 13:47:00 KotH: That's good to hear. Jul 09 13:47:31 georgem: but please be aware, that a lot of the small assembly shops dont know how to solder BGAs Jul 09 13:47:50 georgem: and there are even a few who claim to know it, but dont (and screw up royaly) Jul 09 13:48:15 georgem: if you make a protoype run, let it do by someone who does BGAs often Jul 09 13:48:16 'Lead-free alloys such as SAC alloys have slight higher surface tensions when compared to 63/37.' Jul 09 13:49:03 main differences I've seen is that you have to be more careful of voiding, and it doesn't come out as shiny Jul 09 13:49:06 KotH: We would probably fall into that category. Which is why we take BGA some place else. Although they have done them before with the pick and place machine we have. Jul 09 13:49:52 Russ: voiding? Jul 09 13:50:10 Russ: yes, judging lead free solder is a lot more difficult than leaded solder Jul 09 13:50:15 if your profile isn't good, you can get outgassing from the flux at the wrong time and get bubbles in your solder joint Jul 09 13:50:27 Russ: but with a bit of experience, good and bad solder joints are easy to tell apart Jul 09 13:50:36 Russ: ah.. Jul 09 13:50:56 http://www.process-sciences.com/images/cracked_bga_void.jpg Jul 09 13:55:51 Russ: Do you have many years of experience doing this sort of thing or is this something you picked up rather quickly? Jul 09 13:56:51 picked it up rather quickly, started with reflowing just regular smd boards, then made some bga test boards and reflowed some cheap bga components Jul 09 13:56:52 georgem: you can pick those things up rather quickly, just do a few boards and look what failes Jul 09 13:57:28 georgem: there are a few guidelines and standards for assembly companies out there. these usually explain what is done and why Jul 09 13:57:41 georgem: if you have half a day time, google for them Jul 09 13:57:43 pried off the bgas on some of them to get a look at the joints, saw more voiding than I'd like, looked up information on that, adjusted my stencil for less paste, adjusted the profile for longer dwell time for the flux Jul 09 13:57:51 encouraging Jul 09 13:58:52 even having to buy a bunch of tools, hot air gun, solder station, toaster oven, pid controller, etc, saved quite a bit of money vs having an assembly house do things Jul 09 13:59:17 Russ: And I already have most of those tools available to me Jul 09 13:59:29 not sure about a pid controller Jul 09 13:59:54 it controls the toaster oven and lets you setup a consistent temperature profile Jul 09 14:00:32 georgem: having the right temp profile is key Jul 09 14:00:49 azonberg over on ##electronics is also playing with soldering large BGAs at home. Jul 09 14:00:51 Russ: how do you deal with humidity with the biger cases (like 700 pin bgas)? Jul 09 14:00:51 morning Jul 09 14:01:00 morning Jul 09 14:01:01 koth - proper packaging. Jul 09 14:01:04 greetings mranostay Jul 09 14:01:10 KotH, I keep them in their sealed bag until assembly time Jul 09 14:01:10 Or a bake cycle Jul 09 14:01:26 I do have a dry box for some components Jul 09 14:01:38 Russ: how do you keep the box dry? :) Jul 09 14:01:48 silcagel and baking? Jul 09 14:01:51 its air tight and has a crap load of desiccant Jul 09 14:02:11 some of which can be baked and reused Jul 09 14:02:12 so ka Jul 09 14:03:17 but yes, if you live somewhere moist and/or can't store components well, a bake cycle for critical components seems like a smart thing to do Jul 09 14:03:37 (before assembly of course) Jul 09 14:03:48 buenos dias Jul 09 14:03:54 añguien habla esapñol? Jul 09 14:04:03 me puede ayudar? Jul 09 14:04:29 tuet mer jo schaurig leid, aber do redemer alli innere schoggisproch Jul 09 14:04:34 can you help me? Jul 09 14:04:47 only if you speak in a language i understand Jul 09 14:04:55 espaolo ingles? Jul 09 14:05:03 and you have to speak the words while typing so i can hear them Jul 09 14:05:07 Hello all, I just updated my BBB using https://s3.amazonaws.com/angstrom/demo/beaglebone/BBB-eMMC-flasher-2013.06.20.img.xz Jul 09 14:05:37 puedes leer español? Jul 09 14:05:42 connected it to my LCD7 cape and after the auto login it goes to a black screen with a cursor in upper left corner. The GUI never comes up Jul 09 14:05:50 Fercho: nei, mer redet do ka komischi sproch Jul 09 14:06:05 can you read spanish? Jul 09 14:06:07 Russ: we used to store dies at work.. that's a major pain ^^' Jul 09 14:06:18 Fercho: yes, sure i can read it. i just dont understand it Jul 09 14:06:40 anybody ever run into that problem? Jul 09 14:06:40 have a fix? Jul 09 14:06:40 ok Jul 09 14:06:44 mierda Jul 09 14:07:23 woth the BBB i can run java aplication? Jul 09 14:07:26 with Jul 09 14:07:30 hehehe Jul 09 14:07:35 hey, mierda, I know what that means Jul 09 14:07:51 Fercho: painfully probably Jul 09 14:08:29 greetings alan_o Jul 09 14:08:37 alan_o: long time not read! Jul 09 14:08:41 hi Koth Jul 09 14:08:43 yeah Jul 09 14:08:47 Too much stuff going on Jul 09 14:09:05 now I get to be back in the "office" for a while Jul 09 14:09:21 how's #beagle been? Jul 09 14:09:31 trollish as ever Jul 09 14:09:48 there are a few new gems on 26-26-54 Jul 09 14:10:01 oh.. and we finaly have our own religion Jul 09 14:10:08 yeah? Jul 09 14:10:33 yeah.. we praise the delicious chocolate troll! Jul 09 14:10:40 i need desing a electrostimulation whit de BBB, i can generate the control signals from BBB to another circuit? Jul 09 14:11:03 Yes, you can generate arbitrary digital waveforms Jul 09 14:11:25 Fercho: depends on the signals you need to generate Jul 09 14:12:11 also must have a tft Jul 09 14:12:16 okok Jul 09 14:12:39 digital signals < 200Hz Jul 09 14:13:33 but de aplication must run from ubuntu? Jul 09 14:13:42 or?? Jul 09 14:17:45 the aplication must be java aplication? Jul 09 14:17:48 help e please Jul 09 14:18:25 are you talking about bonescript? Jul 09 14:20:52 yes Jul 09 14:21:36 you can use bonescript, you don't have to Jul 09 14:21:52 bonescript isn't based on java though Jul 09 14:22:17 its based on node.js, which is javascript Jul 09 14:23:01 okoko Jul 09 14:30:46 hi mru ;) Jul 09 14:30:50 (also in Dublin) Jul 09 14:31:00 Hello Jul 09 14:32:07 what kind of serial cable should be used on beaglebone black? Jul 09 14:33:03 RockyZheng: you need to interface with the serial header, details should be in the SRM. IIRC it's 3.3V logic levels. Jul 09 14:33:23 I see the header Jul 09 14:33:35 but i don't have the FTDI cable Jul 09 14:33:45 btw, what is SRM and IIRC? Jul 09 14:34:16 https://www.google.com/search?q=beagleboneblack+srm Jul 09 14:35:04 ok, system reference manual Jul 09 14:35:39 IIRC = If I Recall Correctly Jul 09 14:36:31 quite complicated, IIRC, i almost can;t find this definition by google Jul 09 14:37:25 for me it comes up as 4th result from the top: www.urbandictionary.com/define.php?term=iirc Jul 09 14:37:29 it seems that i need to got some FTDI cables Jul 09 14:38:39 commonly people use USB-to-serial cables based on FTDI for this, yes Jul 09 14:39:01 yes Jul 09 14:39:23 anyway, thanks Jul 09 14:40:45 thanks Jul 09 14:41:06 45 $ gracias muchachos me compro unas 2 Jul 09 14:54:36 Fercho: hint: the bbb runs linux. anything you can do on your pc, you can do on bbb as well Jul 09 14:55:06 Fercho: accessing I/O pins works from all languages. some make it easier, some make it a bit more cumbersome Jul 09 14:55:43 Fercho: what language you want to use highly depends on how accurate your signals need to be and what kind of signals you want to generate Jul 09 14:55:54 Fercho: most accurate for PWM style stuff is to use the PWM module Jul 09 14:56:21 Fercho: if it is a signal that needs to be non-periodic, you have to do it by hand Jul 09 14:57:27 Fercho: if you need high accuracy in the way the signal looks, have a look at the PRU module, there you can produce cycle exact waveforms with up to 200MHz Jul 09 14:57:52 Fercho: but the PRU is a bit more complicated to program Jul 09 15:04:07 rf cape came! rf cape came! hurray for rf cape caming! Jul 09 15:06:06 bradfa, gimme Jul 09 15:06:07 where? Jul 09 15:09:10 <_av500_> bradfa: rf cape caning? Jul 09 15:10:22 panto, on my desk Jul 09 15:10:26 ina box Jul 09 15:10:31 * bradfa opens box now Jul 09 15:10:36 no fun that way Jul 09 15:11:04 * bradfa EXPLODES box now! Jul 09 15:11:34 blowing stuff up ftw Jul 09 15:11:56 cco says no software supports, no kidding :) Jul 09 15:12:04 * bradfa might write cc1101 driver... Jul 09 15:13:28 keep in the loop Jul 09 15:13:32 that stuff interest me Jul 09 15:13:34 k Jul 09 15:13:52 which linux ml would a driver like that go to? linux-netdev? Jul 09 15:14:03 would just be PHY layer, really first Jul 09 15:14:25 just feeding / eating fifos Jul 09 15:14:35 mac layer could be anything on top of that, like 802.15.4 Jul 09 15:14:36 mourning Jul 09 15:14:45 moaning, ka6sox :) Jul 09 15:15:14 * ka6sox mumbles MOAR Coffee! Jul 09 15:16:32 * KotH hands ka6sox a cup of turkish coffee Jul 09 15:16:59 turkey, in coffee? :) Jul 09 15:17:27 bradfa: extra strong, for your JIHADy needs :) Jul 09 15:19:34 KotH, a demitass? Jul 09 15:21:10 ka6sox: fincan :) Jul 09 15:22:34 http://en.wikipedia.org/wiki/Turkish_coffee#Preparation Jul 09 15:25:46 KotH, can I have extra foam please? Jul 09 15:26:08 I want some! Jul 09 15:31:37 ka6sox: a turkish coffee w/o foam is not a turkish coffee Jul 09 15:31:46 ka6sox: but making it with extra foam is .. difficult ^^' Jul 09 15:31:57 KotH, I know..its the Peak of the Art... Jul 09 15:31:59 :) Jul 09 15:32:05 mranostay, you're being blamed for things in #beagle-gsoc Jul 09 15:32:08 * KotH is not good at it ^^' Jul 09 15:32:19 bradfa: well, isnt he to blame? Jul 09 15:32:25 bradfa, tis not his fault...I take the entire blame. Jul 09 15:32:37 * KotH would still blame mranostay Jul 09 15:32:49 okay... Jul 09 15:32:54 if you insist Jul 09 15:33:37 bradfa: someone needs a scapegoat Jul 09 15:34:24 bradfa: help me out there, mate! i need a 24V 200mA LDO. available in single pieces. do you have any recomendations? Jul 09 15:34:29 mranostay, your tables are fine...mine...are dodgy Jul 09 15:34:51 KotH, what input voltage? Jul 09 15:35:05 28V nominal, 32max Jul 09 15:35:12 up to 36V is pretty simple Jul 09 15:35:40 yes, but most of the ones that go up that high are not stocked at dk or mouser Jul 09 15:36:03 or have this insane TO-220 case ;) Jul 09 15:36:29 * KotH is surprised that he didnt stumble over any TO-3 yet Jul 09 15:37:38 mranostay, you better hide Jul 09 15:38:29 ok, so who knows about the sikrit invocation of accessing the other PRUs GPO/GPI Jul 09 15:38:35 sxin, sxout, but how? Jul 09 15:38:36 KotH, output power or input? Jul 09 15:38:45 bradfa: output Jul 09 15:38:45 ah, me should read Jul 09 15:38:59 you're dropping 8 V at 200 mA? Jul 09 15:39:05 gotta heat sink? Jul 09 15:39:21 TO-220 has it's uses Jul 09 15:39:22 :) Jul 09 15:39:29 yeah :) Jul 09 15:39:41 i'd prefere a DPAK or something similar Jul 09 15:40:21 monster power plane with plenty of vias :) Jul 09 15:40:41 no need Jul 09 15:40:57 for DPAK there are solderable heatsinks available Jul 09 15:41:50 TIL ^^ Jul 09 15:42:20 KotH, LM317M? Jul 09 15:42:28 ti part Jul 09 15:44:01 purrrrfect! Jul 09 15:44:04 thanks a lot! Jul 09 15:44:26 * KotH makes a note to bring bradfa some extra chocolate to ELCE Jul 09 15:44:28 caturday already? Jul 09 15:44:37 * bradfa won't be at ELCE :( Jul 09 15:44:46 ka6sox: ah the PRU tables we did a while back? Jul 09 15:44:55 bradfa: then someone else will eat your chocolate Jul 09 15:44:57 bradfa: ok, i'll give your share to ka6sox, he can bring it to you Jul 09 15:45:00 * bradfa got put on terrorist no-fly list by wife Jul 09 15:45:12 KotH, yes! Jul 09 15:45:15 bradfa: really now? Jul 09 15:45:15 bradfa: by wife? not by #beagle? Jul 09 15:45:27 he's married to #beagle Jul 09 15:45:41 that explains a few things Jul 09 15:45:52 it's possible that I could marry #beagle now, maybe that's part of the NY state law... Jul 09 15:46:30 wasnt there a couple of years ago a japanese who wanted to marry a anime character or something like that? Jul 09 15:46:42 * KotH wonder how that turned out Jul 09 15:46:43 did they legalise polygamous marriages with trolls? Jul 09 15:46:58 mru, supreme court says we can marry whoever we want, or something Jul 09 15:47:08 not sure if trolls are covered, let me check Jul 09 15:47:26 I'm aware of the ruling Jul 09 15:47:43 thought it only covered marriage between two people Jul 09 15:47:50 bradfa: you really on the list or just joking? Jul 09 15:48:11 * bradfa jokes Jul 09 15:49:26 holy cow! the LM117 is still available in TO-3! Jul 09 15:50:33 mranostay, yes, those ones Jul 09 15:51:59 * mranostay reports bradfa to the TSA Jul 09 16:21:17 bradfa: i'm thinking of taking Photography as an elective you should enroll too :P Jul 09 16:22:28 KotH, can you bring the chocolate sticks? Jul 09 16:26:31 hmm so my GPS has no clue that a Aloha, OR exists Jul 09 16:41:52 ka6sox: what chocolate sticks? Jul 09 16:42:31 mranostay: i think, you have been brainwashed to think that aloha exists, while infact it's nothing more than a crossroads in the middle of nowhere Jul 09 17:05:24 hello Jul 09 17:05:29 emeb: Just sent you a pull request on bcc_lib Jul 09 17:05:30 everybody Jul 09 17:05:39 i have a question Jul 09 17:05:50 helpppp: Don't ask to ask, just ask :D Jul 09 17:06:07 jmoyerman: kk Jul 09 17:06:12 anything know a library en C++ for ADC converter en BBB Jul 09 17:07:03 i don´t want to read with sheel comand Jul 09 17:07:15 i want to programe the registers Jul 09 17:08:44 helpppp: then access the sysfs files directly Jul 09 17:09:08 Koth how? Jul 09 17:09:21 just file regular files Jul 09 17:09:25 * KotH points at the FM Jul 09 17:09:25 like* Jul 09 17:09:26 helpppp: http://beaglebone.cameon.net/home/reading-the-analog-inputs-adc Jul 09 17:09:53 * KotH points at jmoyerman Jul 09 17:11:45 * KotH lols at "Erlauben dir Auferstehung des Sie!" and "Schutzen des Recht der irgerlich!" Jul 09 17:12:47 mranostay, link to enroll? Jul 09 17:13:47 emeb: Thanks Jul 09 17:14:31 jmoyerman: thank you. I appreciate the help getting things working. Jul 09 17:15:05 emeb: yeah. that other chap forked, but never pull requested, so I just included his change. I like to push back as much to the community as I can, even if it is simple. Jul 09 17:17:34 jmoyerman: indeed. Jul 09 17:18:38 I can think of a few enhancements that might be nice, but it's usable as-is. Once we figure out what's up with the BBB preventing self-config it will be good to add verification support on the spi flash. Jul 09 17:19:17 Yeah. I've noticed that too. I think it's a difference between the eeprom and the dts configuration. It's on my to-do list, but it's about three items down, i'll get to it later this week, because our app needs the self config to work. Jul 09 17:20:23 <_Sy_> hello Jul 09 17:20:46 hi _Sy_ Jul 09 17:20:48 jmoyerman: ssi first showed that the BCC will self config on a BBB if J8 is left unconnected. Jul 09 17:20:52 is there a real db9 serial port cape yet for the bbb? Jul 09 17:21:14 mranostay, ^^^ weren't you working on one? Jul 09 17:21:16 there's something on J8 that interferes with the FPGA startup. I haven't had the time/resources yet to track that down. Jul 09 17:21:43 emeb: I haven't even flashed our FPGA yet honestly, my design isn't "there" yet, but i've found even with disabling the hdmi and things that it doesn't work. Jul 09 17:22:37 emeb: problems with BCC design? Jul 09 17:22:38 jmoyerman: HDMI shouldn't have any effect - none of those pins are connected to the FPGA. It's something on the eMMC bus I suspect. Jul 09 17:22:48 kfoltman: not "problems" per-se Jul 09 17:23:01 Ooh... I thought there was an spi conflict with the hdmi... what am I thinking of Jul 09 17:23:04 * jmoyerman needs more coffee Jul 09 17:23:19 more like unfinished design aspects :D Jul 09 17:23:21 more like compatibility issues with the BBB which were unanticipated since the BCC was designed before the BBB came out. Jul 09 17:24:16 * bradfa thinks sd cards are slow.... Jul 09 17:24:32 * jmoyerman knows that class 4 cars are slow. Jul 09 17:24:40 class 4 cars! Jul 09 17:24:46 cards* Jul 09 17:24:48 d'oh Jul 09 17:25:00 jmoyerman, class is bs when used as a file system Jul 09 17:26:46 Oh? Jul 09 17:27:16 yes Jul 09 17:27:28 class only makes sense when comparing how cameras write, in large chunks Jul 09 17:27:34 Ooh. Jul 09 17:27:51 and only make ssense when card has all blank erase blocks first Jul 09 17:28:02 if not all those are that way, class is meaningless Jul 09 17:28:06 at least according to sd spec Jul 09 17:28:15 ooh. interesting Jul 09 17:28:22 more useful is to know how many random access open-au the controller inside the card supports Jul 09 17:28:37 emeb: ok, at least I can wait before ordering the components for now, need to practice soldering on simpler boards anyway Jul 09 17:28:40 open-au == open erase blocks Jul 09 17:35:12 kfoltman: BCC mostly works w/ BBB but the FPGA doesn't self-config from spi flash at powerup when P8 is connected for some reason. Leaving P8 disconnected allows it to start up normally. Jul 09 17:36:52 hey all.. does anyone know if it's possible to get U-Boot to NOT reset the processor after a data abort? Jul 09 17:37:23 Basically I'm trying to debug the data abort in some simple asm code and want to be able to inspect the state of the board Jul 09 17:37:34 ooh.... the fpga doesn't config, i thought you meant the bbb doesn't config the cape. Jul 09 17:38:11 hum, I'm sure you could put more than 4 serial ports via the PRU Jul 09 17:38:21 maybe even more if you have lower bit rates Jul 09 17:38:22 panto: depends on the baud rate you need Jul 09 17:38:41 emeb: I'm talking to pcw about my bcc project, and he suggests I might want spi sclk on a gclk pin in the future Jul 09 17:38:45 I'd say 115200 is the max Jul 09 17:38:58 so x8 oversampling that's about 1us per sample Jul 09 17:39:01 doable Jul 09 17:39:47 you can also use the start/stop bit time to your advantage Jul 09 17:39:50 TI did a sheet on it... Jul 09 17:39:56 I know Jul 09 17:40:27 ah. ok. Jul 09 17:40:37 but max was 4 uarts Jul 09 17:40:47 and they used mcasp Jul 09 17:40:52 I'm talking about raw bitbanging Jul 09 17:42:01 vvu|Mobile, ping Jul 09 17:42:16 I wish mdp was around... Jul 09 17:42:18 paging mr. mdp Jul 09 17:43:43 d'oh... Jul 09 17:44:38 oh, ti, you announce cc1200 so I see it today and there's no cc1101 dev kit rf connector version of the kit? wtf? I just got my rf cape... Jul 09 17:44:50 * bradfa wants big fifos Jul 09 17:45:32 and you can't lie? Jul 09 17:45:43 good evening Jul 09 17:45:44 ssi: that's all well and good, but for configuring the spi_sclk needs to come in on the CCLK pin as well, and that's not a gclk. You'd have to double up and send it to two pins and that's wasteful on the VQ100 package. Jul 09 17:45:53 panto, exactly! Jul 09 17:46:20 emeb: I'm not too concerned for my application... I'm wondering if I can greenwire it over Jul 09 17:46:28 ssi: if/when we do an S6 version in the 144-pin pkg then we can consider it if there are pins left over. Jul 09 17:46:28 I only need the SPI, no other pins Jul 09 17:46:32 yea Jul 09 17:46:44 I may end up doing a slightly different board for the s6 than you do Jul 09 17:46:46 ssi: do you really need gclk-level of performance from spi clock? Jul 09 17:46:48 we'll have to see where we both end up :) Jul 09 17:46:52 I dunno Jul 09 17:47:02 how fast are you planning on clocking your SPI/ Jul 09 17:47:06 I might end up needing to push the bandwidth limits of the mcspi Jul 09 17:47:11 which I think is 48mbit? Jul 09 17:47:13 gclk is really only helpful if you're driving _lots_ of logic Jul 09 17:47:14 48 MHz baby! Jul 09 17:47:27 and spi sclk only runs to the shift register of the spi slave. Jul 09 17:47:39 well if I use a shift register, I have to oversample 5x I think Jul 09 17:47:45 that's where I ended up on the last one anyway Jul 09 17:47:46 huh? Jul 09 17:47:53 ur doin' it rong. Jul 09 17:47:56 probably Jul 09 17:47:59 you know how good I am at this Jul 09 17:48:09 spi clocks should be fully synchronous and 1 bit/clk. Jul 09 17:48:30 yea on the last slave I did, I kept it entirely in the fpga clock domain Jul 09 17:48:36 and oversampled spi Jul 09 17:48:43 ugh Jul 09 17:48:45 but I guess I can just cross clock boundaries further in Jul 09 17:49:10 do it in the spi clock domain, so much easier Jul 09 17:49:24 spi parallel data is slow enough that if you've got boundary crossing issues you can make a nice state machine to handle it. Jul 09 17:49:29 I need to go ahead and dig into the existing hostmot firmawre Jul 09 17:49:34 yeah Jul 09 17:50:05 you've got a minimum of 8 spi clock cycles to hand the parallel data over the boundary. Jul 09 17:50:36 so just delay the rising edge of CS and trigger a load to another register in the main clock domain. Jul 09 17:51:15 ugh I hate ISE projects so much Jul 09 17:51:19 they're so rcs unfriendly Jul 09 17:51:49 I always keep thinking, that maybe, someday, xilinx will discover revision control Jul 09 17:51:56 doubt it :( Jul 09 17:52:06 project -> cleanup project files :D Jul 09 17:52:07 <_Sy_> Just had a really strange fault on one of my BBB's....it shut itself down and depsite unplugging and plugging in the USB it wouldn't power back up...until I power cycled the hub. Jul 09 17:52:10 <_Sy_> USB hub. Jul 09 17:52:26 so you were back powering? Jul 09 17:52:30 <_Sy_> yep Jul 09 17:52:58 <_Sy_> but I have two BBB's running off the same USB hub and the other was fine Jul 09 17:54:38 not completely sure from the schematic that its possible to backpower through the usb host connector Jul 09 17:54:57 <_Sy_> Its running ok now... Jul 09 17:55:17 d'oh. i hate debugging fpga designs. Jul 09 17:55:32 that's why you debug verilog modules instead :) Jul 09 17:55:42 (or vhdl) Jul 09 17:55:46 <_Sy_> I wonder if it overheated...it is quite warm Jul 09 17:56:29 <_Sy_> oh...just got a power surge reported on usb hub....wtf? Its gone done again. Jul 09 17:56:54 <_Sy_> is there any issue with UART 4 or UART 5 I'm using these for two way comms...between BBB's. Jul 09 18:00:12 <_Sy_> my application sends data on UART4 and receives data on UART5, it seems that after a short period this causes a surge on the USB, then power is cut off to the offending BBB....only resolution is to power cycle USB hub to reset....anyone ? Jul 09 18:02:00 <_Sy_> I've connected UART4 Pins P9-11 and P9-13, UART5 Pins P8-38 and P8-37, crossing over TX and RX between boards.... Jul 09 18:03:33 <_Sy_> I'm I home alone? Jul 09 18:04:02 looks like mru is at the Guiness brewery. Jul 09 18:04:36 emeb, were you able to make the eMMC disappear with the resistor on the sysboot ine? Jul 09 18:06:52 ka6sox: yes Jul 09 18:07:08 didn't help the BCC startup issue tho Jul 09 18:07:15 kk Jul 09 18:07:40 I guess I need a 555 then :P Jul 09 18:07:54 do they make a 555 in TSSOP? Jul 09 18:08:28 look at reset managers? Jul 09 18:08:44 I have used them in TO92 packages, I think they come in SOT as well Jul 09 18:08:57 ssi, there is only 1 sys_reset on the BBB Jul 09 18:09:16 and it is both on the external and internal busses Jul 09 18:09:21 there is no distinction. Jul 09 18:09:40 so that means the CPLD will immediately configure when reset comes off Jul 09 18:09:40 ok back up... you're trying to hold a line high or low? Jul 09 18:09:43 or what are you trying to do exactly Jul 09 18:09:45 low Jul 09 18:09:57 till a time to be determined Jul 09 18:10:08 yea that's what the reset manager is for Jul 09 18:10:12 it's just a time delay Jul 09 18:10:37 has to be externally setable by a resistor or soethin Jul 09 18:10:40 g Jul 09 18:10:52 ssi, a 555 works too :P Jul 09 18:10:53 http://ww1.microchip.com/downloads/en/devicedoc/11187f.pdf Jul 09 18:10:54 something like that Jul 09 18:10:58 yea but this is SIMPLE Jul 09 18:12:02 the question is whether 485ms is enough time to clear those pins of the eMMC Jul 09 18:12:26 trying to find one with a confugurable time Jul 09 18:13:13 in reality...the CPLD doesnt' need to be UP till the app runs Jul 09 18:14:02 (or it gets reprogrammed) Jul 09 18:14:19 where's the cpld? Jul 09 18:14:27 on the cape Jul 09 18:14:34 on the bcc? I don't recall it havign a cpld Jul 09 18:14:42 no, different cape Jul 09 18:14:45 oh ok Jul 09 18:17:41 emeb, do you remember which pins you were seeing movement on that were causing issues with m0,m1,m2? Jul 09 18:19:29 ka6sox: it's not the m? pins that are involved - those are isolated off by themselves. Jul 09 18:20:30 it's the VS[2:0] pins which are tied to the GPMC/eMMC buses that I thought might cause problems. Jul 09 18:21:02 but I took a look at those during boot-up and they didn't seem to be in a bad state. Pulling them didn't help. Jul 09 18:22:53 <_Sy_> https://groups.google.com/forum/embed/?place=forum/beagleboard&showsearch=true&showpopout=true&showtabs=true&hideforumtitle=true&parenturl=http%3A%2F%2Fbeagleboard.org%2FCommunity%2FForums#!category-topic/beagleboard/beaglebone-black/vlV7jtwxpSQ Jul 09 18:22:58 <_Sy_> any ideas? Jul 09 18:23:59 emeb, I don't see a reference to VS[2:0] on pg3 of the schematic Jul 09 18:25:08 are these part of the SPI0 lines? Jul 09 18:26:27 ka6sox: those are secondary functions of pins 29-31 Jul 09 18:28:15 GPMC_AD12,GPMC_AD13,GPMC_WEN Jul 09 18:34:15 ya Jul 09 18:35:05 good catch, that would have caused crashes on BoneTag too Jul 09 18:50:10 hello there o/ Jul 09 18:51:16 just fyi for anyone interested, Circuitco is looking to hire "maker" for an entry level position in the dallas/ft.worth area Jul 09 18:51:33 if you or someone you know is interested drop me a resume - danders@circuitco.com Jul 09 19:07:41 Hello i have a littel problem with my beaglebone black and a wifi dongle Jul 09 19:07:58 Can anybody help me? Jul 09 19:10:27 Hello. does the BeagleBone Black have support for USB 1.1 devices? What Linux driver does the USB controller use? I have a Raspberry Pi which uses dwc_otg, and it seems to be giving me issues. Jul 09 19:12:20 Hello jesselang, I have Debian on my SD-Card an on the eMMC Angstrom if i boot form the SD-Card then work my wifi dongle very fine, but if i boot from eMMC i can not found a wlan but if i make "lsusb" i can see the Dongle Jul 09 19:12:54 The wifi chip is RTL8191SU Jul 09 19:20:01 Guest70615, sorry, I'm not much help there. Jul 09 19:21:01 Thanks Jul 09 19:21:07 what's the difference between capemgr.enable_partno and extra-override? Jul 09 19:21:50 Gui_, the first one is exactly like issuing the echo >slots command Jul 09 19:22:07 the other has to do with standard capes defined in the dts Jul 09 19:23:21 so if I'm making my own dts files (to enable SPI, for instance), i should use the enable_partno? Jul 09 19:23:57 and if I want to modify something from an existing cape, I use the override Jul 09 19:25:23 <_Sy_> I must be getting old.... Jul 09 19:26:03 <_Sy_> Was looking for a good book on Node.js and writing C modules for it and stumbled upon Go....never heard of it before. Jul 09 19:27:25 Golang? Jul 09 19:27:43 <_Sy_> yep Jul 09 19:29:44 <_Sy_> http://jaxbot.me/articles/benchmarks_nodejs_vs_go_vs_php_3_14_2013 Jul 09 19:30:40 _Sy_, where's C fall on that? Or asm? Jul 09 19:30:53 _Sy_, and what about just doing fastcgi behind a decent web server? Jul 09 19:31:06 <_Sy_> CGI isn't very scalable tho. Jul 09 19:31:12 _Sy_, since when? Jul 09 19:31:29 <_Sy_> Because it requires a seperate process for each instance. Jul 09 19:31:31 fastcgi will just spawn another process if it needs to Jul 09 19:31:49 _Sy_, you can also have a multithreaded process behind fastcgi Jul 09 19:32:01 fastcgi != cgi Jul 09 19:32:19 fastcgi > cgi is more correct, you can use fastcgi just like cgi :) Jul 09 19:32:23 <_Sy_> I can't really comment as I don't have any experience of fastcgi Jul 09 19:32:31 _Sy_, it's fast ;) Jul 09 19:33:16 <_Sy_> I was looking for a replacement to our current LAMP solution...whilst it works, the performance boost looks worth the effort to change to Node.js Jul 09 19:33:41 Is PHP that bad, performance wise? Jul 09 19:34:13 <_Sy_> According to several reviews I've read, its very much slower....I really like PHP, but I haven't seen anything that shows it out performing node Jul 09 19:34:24 <_Sy_> but looking at Go, its seems faster still than node.js Jul 09 19:34:38 Well, node.js uses a JIT compiler, so it should be much faster indeed, but is PHP really a performance bottleneck here? Jul 09 19:34:57 before you go abandoning anything, make sure it's worth your time. hardware's cheap these days Jul 09 19:35:12 I've heard you can buy a 1GHz dev board for about 45 euro ;) Jul 09 19:35:14 <_Sy_> Depends on what you do with it...I do lots of AJAX stuff which gets the server to work Jul 09 19:35:31 Go FTW :D Jul 09 19:35:41 _Sy_: you can always write your own apache module in C ;) Jul 09 19:36:13 i wrote my own webserver in a class. it was terrible Jul 09 19:36:14 <_Sy_> Yep, but Apache and PHP are quite large in comparison to node aren't they ? Jul 09 19:36:22 kfoltman, I've heard you can buy a few GHz quad core x86 for < $1000 Jul 09 19:36:34 bradfa: I was going for an on-topic joke ;) Jul 09 19:36:43 kfoltman, oh, mine's not a joke? Jul 09 19:36:59 where's mranostay when we need to x86 all the things... Jul 09 19:37:22 bradfa: did I accidentally end up in #minnowboard? :D Jul 09 19:37:44 kfoltman, don't bite the lure! there's a scary man up above who will tear your innards out and eat you! Jul 09 19:38:01 man? or is he just a troll? Jul 09 19:38:08 where can I find a list of all optargs my kernel accepts? Jul 09 19:38:15 kfoltman, dunno, we'll have to bite the lure to find out! Jul 09 19:38:23 Gui_, in kernel source? Jul 09 19:38:31 * mranostay eats bradfa and kfoltman Jul 09 19:38:33 only looking at the source? Jul 09 19:38:56 Gui_, well, definitely in the source for sure Jul 09 19:38:57 Gui_: I vaguelly recall I've seen something in some .txt file in Documentation/ but memory is fuzzy Jul 09 19:39:02 I imagined that, but was hoping there was a command that could list them Jul 09 19:39:30 * bradfa goes back to reading specs and drinking coffee Jul 09 19:39:39 Gui_: just grep that directory for some obscure kernel option that isn't likely to be just a common word Jul 09 19:39:43 bradfa: i demand a fuzzy pic as proof Jul 09 19:40:04 mranostay, I'll send picture of me reading coffee and drinking specs, one sec... Jul 09 19:41:31 hold on kfoltman, I'm still going after the source code Jul 09 19:42:07 Gui_: tried a quick google search? someone must have written something about 'em? Jul 09 19:42:08 <_Sy_> Would this be ok for as a PSU for BBB ? http://www.amazon.co.uk/KEENE-POWER-SUPPLY-220-240V-OUT/dp/B00131J9BG/ref=pd_sim_sbs_ph_3 Jul 09 19:42:42 _Sy_: one star? Jul 09 19:42:59 <_Sy_> mmmm....didn't notice that...will take another look Jul 09 19:43:01 _Sy_: I got one from Tigal (+UK style plug) and no problem so far Jul 09 19:43:25 <_Sy_> Do you have a link? Jul 09 19:43:28 it's bulkier, but it's rated 2 or 3A and doesn't look like it might fall apart Jul 09 19:43:29 sec Jul 09 19:44:32 _Sy_: http://www.tigal.com/product/2933 for the PSU + http://www.tigal.com/product/2937 for the UK plug, but I think their shipping prices aren't very appealing Jul 09 19:44:40 _Sy_: but I bought it together with my 'bone Jul 09 19:44:56 <_Sy_> ty, I'll take a look Jul 09 19:49:51 why don't you just grab an old cell phone adapter and replace the plug? Jul 09 19:50:04 many adapter are 1A Jul 09 19:50:18 <_Sy_> I could...I have plenty ;) Jul 09 19:51:03 <_Sy_> these look neat: http://www.amazon.co.uk/MITSUGAWA-BS1363-approved-patented-Charger/dp/B0095RDIHG/ref=pd_sim_ce_4 Jul 09 19:52:42 that uk plug is so large... I don't understand why the companies don't take advantage of the available space and make high-current supplies Jul 09 19:53:28 <_Sy_> Doesn't look any bigger than any other plug to me. Jul 09 19:54:20 compare with the italian plug Jul 09 19:54:25 or swiss Jul 09 19:54:53 <_Sy_> Isn't that because the UK plug also has earth and the Euro ones don't ? Jul 09 19:55:05 they also do Jul 09 19:55:17 <_Sy_> I thought they were just two pins Jul 09 19:55:40 <_Sy_> Like US plugs Jul 09 19:55:55 that's because usually the earth is only present when it is needed Jul 09 19:55:59 like US plugs Jul 09 19:56:24 _Sy_: I think they're from Austria so no customs/extra VAT to pay Jul 09 19:57:30 http://www.lulusoso.com/upload/20120314/Electrical_cords_with_a_USA_220_volt.jpg Jul 09 19:57:34 <_Sy_> Bonus with this one plug I can power to BBB's without a USB hub. Jul 09 19:58:19 now check the italian: http://www.global-electron.com/plugs/italian_plug.jpg Jul 09 19:58:50 <_Sy_> Yep...point taken :) Jul 09 20:01:17 so I navigated to Documentation/ and "cat *.* | grep -i fixrtc" (which is one optarg that comes by default on ubuntu) and got no results Jul 09 20:01:20 <_Sy_> Nite all, time to sign off Jul 09 20:12:26 why there has to be so many different linux versions :( Jul 09 20:18:39 he Jul 09 20:18:42 heh Jul 09 20:29:16 hi, how well does the beagle baord black work with ununtu Jul 09 20:36:21 god Jul 09 20:36:34 have you found him yet? Jul 09 20:36:35 impatient fellow Jul 09 20:47:40 enable_partno works with my "custom" built ubuntu, but not with the "standard" armhf release. Jul 09 20:47:49 weird Jul 09 20:48:22 gotta read/learn more, but at least it works by now Jul 09 21:14:55 Hmmm Jul 09 21:15:14 There's a GSoC project for one of the BSDs right? Jul 09 21:20:35 Looking for a pointer, or a tester, for booting a BSD on beaglebone white or black Jul 09 21:23:55 * mranostay trolls Tartarus Jul 09 21:24:23 * Tartarus throws broken FPUs at mranostay Jul 09 21:25:32 Tartarus: we broke them on purpose i'll have you know :P Jul 09 21:26:15 ok, time to go to bed Jul 09 21:26:16 bbt Jul 09 21:45:11 m_billybob you around?
