Jul 02 03:48:41 * emeb_mac is still waiting for the invention of "Mr. Fusion" Jul 02 03:48:57 nails on a bike that can't end badly Jul 02 03:56:03 emeb_mac: Mr Fusion has already been invented. Jul 02 03:56:15 mrpackethead: ? Jul 02 03:56:28 they created it sometime in the future, and its been brought back. Jul 02 03:56:37 its'nt wal mart stocking it in your parts? Jul 02 03:57:08 "the future is already here - it's just not evenly distributed" Jul 02 03:57:25 maybe IKEA will sell you a flat pack one Jul 02 03:57:37 some assembly required Jul 02 03:58:00 just make sure you build it correctly - the consequences could be... dire. Jul 02 04:01:46 df Jul 02 04:02:21 mrpackethead, "Mr." Fusion Jul 02 04:06:20 guess you'd learn how good the DHS is at detecting radiation ) Jul 02 04:12:24 hmm?

I want them to send each other a heartbeat so they both know if the other has a problem. Jul 02 06:41:11 emulate a vax and run vms on them Jul 02 06:41:34 :D Jul 02 06:42:03 <_Sy_> should have read "guides or sites" Jul 02 06:42:08 RxD→TxD; TxD→RxD; GND←→GND Jul 02 06:42:58 <_Sy_> ok, that I know, I'll take a look at the PDF tongiht for pin outs...I've read several posts of people having problems with serial interface on BBB. Jul 02 06:43:40 ofc you need to make sure the pins are muxed Jul 02 06:44:54 <_Sy_> ty, will take a look Jul 02 06:45:30 <_Sy_> anyone here wrote a library or native routine for node? Jul 02 06:46:04 you mean something like termios? Jul 02 06:47:36 <_Sy_> I'm very new to node, but the more I read on t the more I like it...one application I have currently does something when an interrupt occurs....I would like to translate this into a node application to test if node could do the same...so I was thinking of writing a C module that when the interrupt occurs, raises an event that node could fire. Jul 02 06:48:38 ask jkrinder when he shows up Jul 02 06:49:20 <_Sy_> ok ty Jul 02 07:24:10 mroing. trilling.. who is awake Jul 02 07:24:24 swiss_man are you here KotH Jul 02 07:25:55 * KotH JIHADs in Jul 02 07:26:08 * mranostay bikes out Jul 02 07:53:05 mrpackethead: was there anything you want? Jul 02 07:53:39 KotH: got a receipe for stick date pudding? Jul 02 07:54:22 good moring anyway Jul 02 07:54:34 ofc: http://www.chelsea.co.nz/baking-and-recipes/105/sticky-date-pudding-with-butterscotch-sauce.aspx Jul 02 07:54:42 yeah yeah, thats the one Jul 02 07:54:46 you should try it Jul 02 07:54:52 its yum Jul 02 07:55:22 what is self-raising flour? Jul 02 07:55:41 flour that is already mixed with baking powder Jul 02 07:56:02 ahh.. Jul 02 07:56:09 for lazy people Jul 02 07:56:09 sounds like americanism Jul 02 07:56:48 1 cup flour + 1 teaspoon of baking powder Jul 02 07:56:54 mrpackethead: i'll try it when i have time to convert the values into real measures instead of feet, hands and pints of beer Jul 02 07:58:53 (beside, backing isnt a thing when it's 30C outside) Jul 02 08:27:17 KotH: its a dish for when its snowing Jul 02 08:32:06 more seriously, i sent a design away today which included a DS3231 for a RTC Jul 02 08:32:14 hopefully we'll get that to work nicely. Jul 02 08:35:23 KotH: self-raising flour is a dutchism as well Jul 02 08:35:43 mrpackethead: you could argue baking powder is for lazy people as well Jul 02 08:35:45 its a world-.ch'ism Jul 02 08:36:13 possibly, what would you use in stead of baking powder Jul 02 08:36:36 baking powder is a premix of baking soda and creme tartar Jul 02 08:37:01 I admit I never encountered a recipe that called for a different mix of those 2 Jul 02 08:37:07 and cornstratch Jul 02 08:37:12 corn starch. Jul 02 08:37:13 so I stick with baking powder :) Jul 02 08:37:46 actually, most of my baking is simple, so self raising flour will get used Jul 02 08:38:01 i dont' bake Jul 02 08:38:02 :-) Jul 02 08:38:57 that reminds me Jul 02 08:39:05 one of the heating elements crapped out last week Jul 02 08:39:28 should still be inside warranty Jul 02 08:42:57 mrpackethead: got the cape PCB, thanks! Jul 02 08:43:08 mrpackethead: damn.. then i have to wait 3 months for winter Jul 02 08:43:22 kfoltman: cool Jul 02 08:43:30 kfoltman: i got mine all up and running Jul 02 08:43:43 mrpackethead: it looks less scary than I thought, except for the 'sourcing components' part (I don't even have digikey or mouser account yet :D) Jul 02 08:43:44 we have abotu 5 left out of the batch Jul 02 08:44:15 kfoltman: the only part that has been hard to get for osme folks was the osscillator Jul 02 08:44:26 mrpackethead: where did you fab it? it looks very nice Jul 02 08:44:26 but there is a sutiable substitute from DK Jul 02 08:44:50 kfoltman: they are made in Maylasia Jul 02 08:45:08 one of my suppliers, who makes all my pcbs. Jul 02 08:45:34 ah Jul 02 08:45:38 if i sell the next 5, i might get mine for free Jul 02 08:45:39 :-) Jul 02 08:45:40 lol. Jul 02 08:45:52 i made 50, i based the price on selling 40 Jul 02 08:46:01 thought it's some 'popular' fab company Jul 02 08:46:09 its popular with me Jul 02 08:46:12 :) Jul 02 08:46:27 there are cheaper, but they are reliable, quick and dont' often make mistakes Jul 02 08:46:43 i wonder what the next cape project will be Jul 02 08:47:21 mrpackethead: I'll stick to seeed/itead for now - the quality is probably worse, but they're cheap and do very small batches, so it's good enough for now Jul 02 08:47:38 well, BCC looks exceptionally nice Jul 02 08:47:47 yeah..i get 2 day turn around Jul 02 08:48:01 2 day! amazing :) Jul 02 08:48:16 comparing to seeed 1 month or so ;) Jul 02 08:48:20 yes, Jul 02 08:48:24 good morning everyone Jul 02 08:48:33 i dont' ahve months to wait Jul 02 08:48:35 how are we all this fine, gloomy day Jul 02 08:48:49 fine Jul 02 08:48:54 *cough*I'm not here*cough* Jul 02 08:49:18 it's only, just pleasantries - I don't want anything just yet ;) Jul 02 08:50:20 I went to one of the Altera training days where you get the free SoCfpga boards; so I'm currently thinking the evil thoughts about them Jul 02 08:50:59 mrpackethead: the small thingy near the FPGA is the only scary looking component AFAIK Jul 02 08:51:16 yeah, the two SO70 pacakges Jul 02 08:51:21 they are a wee bit fiddly Jul 02 08:51:33 even though the pin pitch is wider than the TQFP Jul 02 08:51:50 I assume I should solder them before the TQFP? Jul 02 08:52:00 i dont' think it woudl make much differnece Jul 02 08:52:28 jsut watch your oritaton of the parts Jul 02 08:52:39 some of them are a little tricky to identify Jul 02 08:53:11 mrpackethead: err I mean U304 Jul 02 08:53:52 not sure if we're talking about the same thing Jul 02 08:54:30 ah there's another one of these :) Jul 02 08:55:08 how do I tell the orientation with those things? they're so small! Jul 02 08:55:30 salut panto Jul 02 08:57:35 aloha Jul 02 09:01:37 aloha, av500 Jul 02 09:02:57 theres a bar across one end Jul 02 09:03:03 thats the pin 1 end Jul 02 09:11:38 mrpackethead: thanks! BTW, looks like one of my workmates was doing SMD soldering for some time and can help me or lend tools Jul 02 09:27:00 Hello! I have installed tk/tcl from source successfully on my BBB runs Angstrom distribution. But when I executed "wish" command it killed the metacity window manager and everything came back to normal when I closed wish'window Jul 02 09:29:11 be careful what you wish for Jul 02 09:30:36 just "$wish" Jul 02 09:30:58 i doubt it killed anythingt Jul 02 09:31:08 and "$wish" looks.. uhm.. wrong Jul 02 09:31:25 No It just killed metacity! Jul 02 09:31:27 if, then it's just `wish` Jul 02 09:31:56 if everything came back to normal, after you killed wish, then metacity was not dead Jul 02 09:32:21 metacity is known to die when launching certain apps Jul 02 09:32:28 o_0 Jul 02 09:32:30 wtf? Jul 02 09:32:49 it's gnome Jul 02 09:32:59 probably only works 'properly' with gnome apps Jul 02 09:33:13 * KotH just read "it's gross" Jul 02 09:33:19 which is probably not that far off Jul 02 09:33:23 indeed Jul 02 09:33:25 It worked well with ssh fowarding X11 Jul 02 09:36:05 it's 11:35.. and i'm tired enought fall asleep ^^' Jul 02 09:36:10 -t Jul 02 09:39:02 +1 Jul 02 09:48:37 * KotH giggles at http://dilbert.com/fast/2013-07-02/ Jul 02 09:49:12 sticky date pudding sounds like a stalker dessert Jul 02 09:49:28 it's kiwiland we are talking about Jul 02 09:49:57 I didn't have sticky date pudding in kiwiland :O Jul 02 09:50:02 now I need to go back Jul 02 09:50:11 av500: can someone set up a dilbert scraper with a proper rss? Jul 02 09:51:52 well that's an easy recipe .. Jul 02 09:56:34 mru: yes please Jul 02 09:56:51 av500: good, you're volunteered Jul 02 10:11:52 back Jul 02 10:16:40 Is it just me or is there a worldwide shortage of BBBs? Jul 02 10:27:19 arbitraryuser: there is a shortage! aliens stole all our stock! Jul 02 10:28:46 KotH: were they *illegal* aliens? Jul 02 10:29:21 oh noez they stole our jobs and they're stealing our BBBs too! Jul 02 10:30:05 and now they stole his internet too Jul 02 10:31:37 test Jul 02 10:31:59 failed Jul 02 10:44:55 http://thread.gmane.org/gmane.linux.kernel/1518978 Jul 02 10:48:32 BUILD.BAT Jul 02 10:48:38 (I'm in South Africa so the only way to buy that isn't insane is via RS components, and they don't have stock until the end of July) Jul 02 10:53:30 arbitraryuser: experience shows that stock numbers are all bogus Jul 02 10:53:37 the best way is to just order Jul 02 10:53:40 to get into the queue Jul 02 10:56:29 bogus? really? Jul 02 10:56:39 yeah, looks like the UK resellers are getting stock much more regularly than their restock dates! Jul 02 10:56:50 I suppose next you'll tell us bogomips aren't real either... Jul 02 10:59:23 mru, +1 Jul 02 10:59:32 they are real to me dammit! Jul 02 11:02:30 hey guys. do the drivers also work with mac os 10.6.8? I would like to be sure before buying it. Jul 02 11:02:57 what drivers? Jul 02 11:03:22 network over usb access Jul 02 11:03:34 it's cdc ethernet Jul 02 11:03:38 any sane os has drivers Jul 02 11:03:42 it is mentioned in getting started guide Jul 02 11:09:20 ok, thanks Jul 02 11:09:52 <_av500_> mru: http://pipes.yahoo.com/pipes/pipe.run?_id=89b2d955766622f7b680561f38b40465&_render=rss Jul 02 11:10:01 <_av500_> mru: I was lazy Jul 02 11:27:13 As every child in kindergarten knows, recursive make is bad (except when it is good, which you learn in Jul 02 11:27:17 primary school). Jul 02 11:29:36 KotH: reminds me of the signal processing course at uni Jul 02 11:29:51 KotH: weeks and weeks of using discrete fourier transforms Jul 02 11:30:16 KotH: and then "here's what we call 'FFT', you can now forget about DFT" Jul 02 11:30:29 KotH, I'm sure gregh will respond nicely after such a lovely response Jul 02 11:30:32 huh Jul 02 11:30:40 fft is just a way of computing the dft Jul 02 11:31:35 yes, but a lot faster than the dft way in the early weeks Jul 02 11:31:58 the naive way is quadratic Jul 02 11:32:16 fft is n log n Jul 02 11:37:04 * KotH has not used dft/fft in ages... everything i do has been z-transformed Jul 02 11:37:38 that's just a dft with the ends joined Jul 02 11:53:39 Hi all, I would ask a question. Which kernel version do you recommend for BBB ? Jul 02 11:54:17 the one that's shipped on the eMMC Jul 02 11:56:07 the one that koen recommends Jul 02 11:56:26 the one that works best Jul 02 11:56:37 and which kernel version is that one ? 3.2 ? Jul 02 11:58:52 3.8 Jul 02 11:59:34 koen, does the default angstrom setup script use oe-core now? Jul 02 12:00:20 Crofton|work: it has for years :-) Jul 02 12:00:30 just doubel checking Jul 02 12:00:47 bad CABAL member ;-) Jul 02 12:01:24 panto, is this kernel DT only ? Where I can get the sources ? Jul 02 12:02:00 it is DT only and all the sources are at beagleboard.org Jul 02 12:03:22 is the one used by angstrom distribution ? Jul 02 12:03:27 yes Jul 02 12:03:38 and ubuntu, and android and all other distos Jul 02 12:05:20 Is this https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.8 ? Jul 02 12:05:22 hi mag, Guest10456 Jul 02 12:05:33 this is ubuntu's kernel Jul 02 12:05:34 damn you feedly Jul 02 12:05:59 eballetbo: no Jul 02 12:06:21 eballetbo: though I guess it is derived from the beagle kernel Jul 02 12:06:45 panto, this is robert nelsons kernel ... nothing to do with ubuntu :) Jul 02 12:07:04 ogra_, yeah, I know Jul 02 12:07:12 but it's the one he uses for ubuntu Jul 02 12:07:16 yeah Jul 02 12:07:20 ogra_: which one runs better on BBB, Ubuntu or Robert Nelson? Jul 02 12:07:39 * panto awards av500 +1 troll point Jul 02 12:07:58 * ogra_ never booted robert nelson .... Jul 02 12:08:14 eballetbo, https://github.com/beagleboard/kernel/tree/3.8 Jul 02 12:08:17 (but then i never booted a BBB either ...) Jul 02 12:08:33 ogra_: I bet you can get BBB further though :-D Jul 02 12:08:44 thanks panto Jul 02 12:08:59 XorA, if i had the HW :) Jul 02 12:09:08 ogra_, excuses Jul 02 12:09:30 pity UDS is no longer live, could have held punting competition, see which board is better for booting! Jul 02 12:09:43 heh Jul 02 12:10:01 * ogra_ expects one or the other live UDS to happen again at some point Jul 02 12:10:18 and the beer distributors demand it :-D Jul 02 12:10:21 probably under different name with different focus though Jul 02 12:11:36 the times for official dev board support in ubuntu are definitely over though ... Jul 02 12:12:28 it's all mirline now in ubuntu Jul 02 12:12:51 well, its all touch and consumer focused now Jul 02 12:13:25 the only arm eare where we still use "boards" is server Jul 02 12:13:36 *area Jul 02 12:14:24 merge, do we know each other ? or what is the reason for dragging me into the intimacy of a private chat ? Jul 02 12:35:25 omg ogra_ Jul 02 12:36:34 heh Jul 02 12:37:08 ogra_: why not arrange the numbers in the PC style, for the convergence? Jul 02 12:37:31 well, i doubt you will see that screen on PCs Jul 02 12:37:48 (and i also doubt it will stay that way ... its their first shot) Jul 02 12:39:04 and while all apps will be usable without unlocking, data access and encryption will require locking Jul 02 12:41:55 ? Jul 02 12:42:01 I wont be able to lock my phone? Jul 02 12:42:17 you will be able to lock data access Jul 02 12:42:40 so I wont be able to lock my phone? Jul 02 12:42:59 as in "i does nothing until that pin is entered" Jul 02 12:43:03 it* Jul 02 12:43:08 if it is locked you will still be able to use apps, bit wont be able to access your data, make calls (except emergency) etc Jul 02 12:43:18 s/bit/but/ Jul 02 12:43:38 is that a case of "be different in order to be different"? Jul 02 12:43:39 there will be settings to define what you allow Jul 02 12:43:52 you lost me Jul 02 12:44:18 settings that will then be dropped gnome-style= Jul 02 12:44:20 settings that will then be dropped gnome-style? Jul 02 12:44:24 "too complicated" Jul 02 12:45:01 well, it is not the app access you want to lock but access to data or any services that cost money Jul 02 12:45:24 no Jul 02 12:45:33 when I want my phone locked, I want it locked Jul 02 12:45:40 I dont want people even to see what apps I have Jul 02 12:45:42 you will be able to define that Jul 02 12:45:47 ... Jul 02 12:45:51 so I can lock it? Jul 02 12:45:51 if you really want Jul 02 12:45:57 yes, indeed Jul 02 12:46:10 but its not the default? Jul 02 12:46:11 it wont be the default behavior (like it isnt on android anymore) Jul 02 12:46:18 ? Jul 02 12:46:22 when I lock my android phone Jul 02 12:46:24 it is locked Jul 02 12:46:26 pretty much Jul 02 12:47:30 it has full access to the camera and to apps you put on the lock screen Jul 02 12:47:44 at least in 4.2 onwards Jul 02 12:47:52 camera yes Jul 02 12:47:57 apps, only if you actively put them Jul 02 12:48:00 its not the default Jul 02 12:48:11 see the difference? Jul 02 12:48:11 all your mobile phones belong to the NSA Jul 02 12:48:23 they are watching everything with the cameras Jul 02 12:48:31 and people wonder why battery life sucks Jul 02 12:49:02 because all data is being sent to motorola Jul 02 12:49:11 and the NSA Jul 02 12:50:00 well, you wont have access to apps there were installed in the user data space ... only default apps of the OS Jul 02 12:50:42 *that Jul 02 12:50:42 will I see the installed apps? Jul 02 12:50:54 no, that would require access to the users data Jul 02 12:51:01 wich is locked :) Jul 02 12:51:13 so I would see an app list with less apps? Jul 02 12:51:25 I hope you have good customer support hotlines Jul 02 12:51:29 you will have ac.cess to some core apps ... camera ... calculator etc etc Jul 02 12:52:20 "Q: my phone only shows some apps" "A: did you lock it?" "Q: I hate you!!!" Jul 02 12:52:58 Crofton|work: Didn't you mean "All your mobile phones are belong to NSA" heh Jul 02 12:53:10 yes Jul 02 12:53:11 since when does 'lock' not mean 'ignore input since phone is probably in pocket'? Jul 02 12:53:12 av500, i dont think thats the plan of our design team ... Jul 02 12:53:28 mru: you are so old school Jul 02 12:53:39 I get that a lot Jul 02 12:53:46 av500, i'm pretty sure you will see all apps but the phone brings up the unlock dialog as soon as you perfoem an action that requires unlocking Jul 02 12:53:58 ogra_: seeing all apps is not good Jul 02 12:54:01 heh, 999 pocket dials will rocket Jul 02 12:54:34 mru: Not sure if its true but someone told me there was a law in some countries that 911/999 or whatever must be able to be dialed when the phone is locked Jul 02 12:54:47 sure Jul 02 12:54:48 georgem: True Jul 02 12:54:58 georgem: its true and its the worlds most stupid law Jul 02 12:54:59 georgem: there's not even a number pad on the lock screen... Jul 02 12:55:22 mru: for smart phones it doesn't really apply, just saying Jul 02 12:55:34 it does Jul 02 12:55:37 nexus 4 - when locked. 'emergency call' text at bottom. Jul 02 12:55:42 Press it, you get a dial-pad Jul 02 12:55:44 especially as too many phones accept 1 anything 1 anything 2 and 9 anything 9 anything 9 as valid :-( Jul 02 12:55:45 right Jul 02 12:55:59 you usually have an emergency button that brings up the number pad Jul 02 12:56:04 XorA: yeah my cheapo crap phone seems to do that Jul 02 12:56:04 oh, I don't have a pin/pattern set Jul 02 12:56:09 XorA: you need to be able to enter it while in a swordfight Jul 02 12:56:23 on the losing end Jul 02 12:56:41 av500: as it turns out my left testicle is very adept at phoning it :-( Jul 02 12:57:04 XorA: Maybe it's a Mexican in homage to Zoro or something :P Jul 02 12:57:08 law* Jul 02 12:57:31 XorA: I hope it does not get jailed... Jul 02 12:58:09 I miss my flip phone. It sucked for everything else but damn it, it was a good phone Jul 02 13:00:32 mranostay, I work in and old Kodak building Jul 02 13:00:44 they did animal testing here... Jul 02 13:00:57 bradfa: ha, I was about to ask does it smell like chemicals Jul 02 13:00:59 and it was the mailing address on all the nuclear paperworks for their reactor Jul 02 13:01:03 XorA: I accidentally bought an app once with my arse. Jul 02 13:01:15 XorA: swiped to unlock, navigated to play store, bought app. Jul 02 13:01:17 georgem, a little bit at the other end of the building Jul 02 13:01:19 SpeedEvil: lol Jul 02 13:01:30 XorA: Fortunately, I caught it within the 15 min period Jul 02 13:02:01 SpeedEvil: I heard you had an expensive arse :-D Jul 02 13:03:27 * mru does not understand people who sit on phones Jul 02 13:04:18 The right sensors, software should be able to detect someones hand from their arse. Jul 02 13:04:29 pretty sad Jul 02 13:04:31 the internet of arses? Jul 02 13:05:09 georgem: elbow or arse would be killer PHB app! Jul 02 13:05:11 +1 Jul 02 13:05:22 +1 Jul 02 13:05:36 georgem: Screw that - a proximity sensor would fix it. Jul 02 13:06:11 SpeedEvil, wouldn't the phone be in proximity to your arse though? Jul 02 13:06:23 * jackmitchell pokes Altera in the eye, bad dog! Jul 02 13:06:35 bradfa: that's the point - you want to turn off the touchscreen when the whole phone is in a pocket/bag/... Jul 02 13:06:50 koen, you will like this Jul 02 13:07:29 Altera have forked and modified the poky into there own weird auto-distro thing Jul 02 13:08:04 "the poky"(tm) Jul 02 13:08:20 a branch of a branch of a branch Jul 02 13:09:20 and on that branch, and on that branch, there was a nest, the prettiest nest you ever did see. With a nest on the branch and the branch on the tree and the tree in a hole and the hole in the ground, and the green grass grew all around all around and the green grass grew all around! Jul 02 13:09:44 that's how they described it at the training day Jul 02 13:09:51 bradfa: I know, I already told them that do a 'bsp' you need to do a bsp layer, not use that POS poky Jul 02 13:10:20 koen: the worst thing is they don't even properly use poky Jul 02 13:10:29 they just use the poky distro settings Jul 02 13:10:42 jackmitchell: I know Jul 02 13:10:45 but none of the actual stuff which might be useful to them like the kernel fragments Jul 02 13:11:00 fragmented kernel? Jul 02 13:11:08 is that like loadable modules? Jul 02 13:11:29 no, 'text fragments' which apply onto defconfigs Jul 02 13:11:35 ah Jul 02 13:11:40 can DT help there? Jul 02 13:11:45 fex it Jul 02 13:12:00 they grep and sed in there defconfig and make oldconfig Jul 02 13:12:23 oldconfigs always work Jul 02 13:12:32 oldschoolconfig Jul 02 13:12:42 no one likes newconfigs, newconfigs are scary Jul 02 13:12:51 lets just keep oldconfig Jul 02 13:12:58 oldconfig never failed us Jul 02 13:12:59 randconfig is the best Jul 02 13:12:59 make oldschoolconfig downloads 2.4... Jul 02 13:13:08 just repeat until it works Jul 02 13:13:25 there is also cargoconfig Jul 02 13:13:39 nobody knows where it is from Jul 02 13:14:24 it also doesn't help that the upstream u-boot, doesn't boot... Jul 02 13:14:45 make cargocultconfig - full of options that might be important Jul 02 13:14:48 on what hw? Jul 02 13:14:59 the new Altera 'socfpga' boards Jul 02 13:15:22 I've got an Arrow SoCkit Jul 02 13:16:14 jackmitchell, newconfig is for those horrible progressives Jul 02 13:16:27 mdp: those damn hippies Jul 02 13:16:31 jackmitchell, are you running nios2? Jul 02 13:16:44 bradfa: no, its an FPGA with a Hard Processor system Jul 02 13:16:49 ah, ok Jul 02 13:16:58 like zynq Jul 02 13:17:01 join in matrimony Jul 02 13:17:22 Hard Float too? Jul 02 13:17:28 yeah Jul 02 13:17:42 mdp, mranostay: I'm in the process of preparing a release with documentation for the other PRU instructions and info that were scrubbed from previous releases. Jul 02 13:18:40 mdp, mranostay: have you seen these magical "incantations" of loading the PRU DT fragments and driver repeatedly? Jul 02 13:18:41 jkridner, excellent! Jul 02 13:18:58 jkridner, thanks for making that happen Jul 02 13:19:09 the folks working on the PRU code are looking to understand where to look for the issue. Jul 02 13:19:27 it doesn't happen consistently, so any hints are appreciated. Jul 02 13:19:48 not I, I haven't yet moved my stuff over to a recent DT fragment kernel Jul 02 13:19:50 new release will include the v2 instructions, scratchpad info, etc.... and an updated assembler. Jul 02 13:20:09 doh! I thought for sure you were using 3.8 with the DT stuff. Jul 02 13:20:23 mranostay: I know you have the nixie stuff.... that seems to be driving most of the examples. Jul 02 13:20:30 jkridner, any news on a *cough* future official release with C compiler? Jul 02 13:20:49 not yet... no ETA on the compiler. Jul 02 13:20:53 c++? Jul 02 13:20:57 cxx11? Jul 02 13:20:58 I am looking for beta testers though. Jul 02 13:21:10 panto has tried it out. Jul 02 13:21:12 jkridner, I'm on 3.8 for new work like arduino..just haven't migrated my pru-based projects that sit idle Jul 02 13:21:24 jkridner: wasn't that reload issue due to a faulty pinctrl patch? Jul 02 13:21:43 koen: is that something fixed in the 06_20 image? Jul 02 13:21:56 more like 04 something Jul 02 13:21:57 * jkridner has no idea what the issue is and has never produced it. Jul 02 13:21:59 check the git log Jul 02 13:22:03 jkridner: hey man, sorry to bug, you have any links or details about that opamp circuit you had in mind for the 3.3->1.8V stuff? Jul 02 13:22:07 it was one of elias' patches Jul 02 13:22:08 every time I load an overlay and modprobe uio_pruss, it works. Jul 02 13:22:12 jkridner, yeah, I have the alpha copy..I'd like to try the newer version after I'm back from the second half of my vacation Jul 02 13:22:53 Spirilis: I can probably take 15 minutes and provide you something today... I was just looking at an op-amp based scalar such that the output impedance of whatever was connected wouldn't matter. Jul 02 13:23:10 jkridner: https://github.com/beagleboard/kernel/commit/31fe876a8a7686eba5f3330cea766d21757f4bcf Jul 02 13:23:12 koen: k, thanks. Jul 02 13:23:25 anything after that shouldn't need that unload/reload Jul 02 13:23:28 jkridner: ah sweet, that sounds good. yeah I figured something like that would be good & universal. I am pretty dumb with analog stuff but I can usually whip circuits together easy enough :) Jul 02 13:23:46 Date: Mon, 13 May 2013 21:29:44 +0200 Jul 02 13:23:52 so 05.13 or newer Jul 02 13:25:09 koen: I'm told by the PRU guys that they still see issues with the 06/20 image. I'll try to get a pastebin of the error or something. Jul 02 13:26:38 and knowing TI people they are not actually running 06/20, but only have a webpage open showing the data Jul 02 13:26:41 date* Jul 02 13:26:49 I had them 'cat /etc/dogtag' Jul 02 13:27:01 * jkridner is making sure the issue can be captured... Jul 02 13:27:06 :) Jul 02 13:27:12 I think one concern was removal, but removal issues are known. Jul 02 13:27:13 jkridner, hi Jul 02 13:27:17 hi panto. Jul 02 13:27:29 jkridner, I have a few remarks about the compiler Jul 02 13:27:52 if you're too stupid to write asm, you're probably too stupid to be using the pru in the first place Jul 02 13:28:02 mru, it's not a matter of being stupid Jul 02 13:28:17 mru, but you've never had a strong feeling about the usefulness of C on the PRU before..have you? ;) Jul 02 13:28:41 you need to do some kind of not so obvious code to interface with linux Jul 02 13:28:53 the vring stuff in assembly would be extra painful Jul 02 13:29:30 so why not write the glue in C, you can always run your time critical stuff in assembly Jul 02 13:29:47 the compiler generates OK code, but not stelar Jul 02 13:30:04 not even on stellaris? Jul 02 13:30:11 heh Jul 02 13:30:16 *groan* Jul 02 13:30:18 er, tivaris Jul 02 13:30:23 not since they called it Tiva! Jul 02 13:30:34 titiva Jul 02 13:30:42 btw, uio_pruss must die Jul 02 13:30:54 reminds me of the marketing rename of "TI RTOS" Jul 02 13:31:04 panto: is the remote_proc driver part of the GSoC effort? Jul 02 13:31:12 jkridner, yeah Jul 02 13:31:17 panto: has it not only just made it mainline? I'm sure I saw it crop up the other day Jul 02 13:31:35 jackmitchell, err, which? uio_pruss? Jul 02 13:31:42 yeah Jul 02 13:31:57 uio_pruss has been in mainline Jul 02 13:32:26 well, the problem with it is that you have memory totally out of whack re: coherency Jul 02 13:32:28 I think it was the DT-fication of it Jul 02 13:32:37 right Jul 02 13:33:02 if you try to do anything 'real' with it, you'll see stale data, etc Jul 02 13:33:33 mdp, btw, I'd like you to take a look at the pru remote proc stuff Jul 02 13:34:26 I've got a couple things I need to have done before end of wed..so I suspect I'll run out of time until I return after next week Jul 02 13:34:34 np Jul 02 13:34:38 but send it over ;) Jul 02 13:34:58 I'll sent it the moment I have the virtual port working :) Jul 02 13:35:03 *serial port Jul 02 13:35:19 virtio is just not trivial Jul 02 13:35:26 fast, but super complicated Jul 02 13:35:54 yep Jul 02 13:37:02 caught your conversation with gregkh yesterday..I feel like he's unaware that the conversation happened long ago that put the ducati folks down the virtio/remoteproc path as to the way to do this stuff Jul 02 13:37:14 too bad they messed up Jul 02 13:37:21 jj2baile: can you add a link to your blog at http://beagleboard.org/project/PRUJTAG/ ? Jul 02 13:37:46 panto, at a high level, I see it mostly as an issue of the work being incomplete Jul 02 13:38:43 panto, plus, that crew is pretty much 100% focused on rpmsg as the client usage..not other client drivers Jul 02 13:38:58 jkridner: ok Jul 02 13:40:44 mdp, even the st modem driver works almost by accident Jul 02 13:40:53 I don't know what kind of arch they do have Jul 02 13:41:02 st-arch Jul 02 13:41:14 but on ours virt_to_phys() on dma_alloc_coherent memory doesn't work Jul 02 13:41:50 av500: corn starch? Jul 02 13:42:02 a-corn st-arch Jul 02 13:43:52 mdp, rpmsg is not the ideal interface for most things Jul 02 13:45:04 panto: does rpmsg include vring transport, or is that something completely different? Jul 02 13:45:16 jkridner, it does include vring transport Jul 02 13:45:26 every virtio interface uses vrings Jul 02 13:45:40 * av500 sings "vring my bell..." Jul 02 13:45:54 * panto awards +1 disco point to av500 Jul 02 13:46:17 do you have any pictures wearing bell bottom pants? Jul 02 13:47:07 is vring related to chris? Jul 02 13:47:10 disco points? Jul 02 13:47:24 av500: that's going to be in my head all day. Jul 02 13:50:15 oh noes jkridner Jul 02 13:52:05 jkridner: my work is done then Jul 02 13:52:10 :-) Jul 02 13:52:41 jkridner: how goes the javascript lately? Jul 02 13:52:58 bursty. http://beagleboard.org/Support/BoneScript Jul 02 13:53:20 examples *finally* starting to show up for stuff. Jul 02 13:54:09 all is wrong with the world! Jul 02 13:56:18 it is just a way of documenting Linux interfaces. can't understand why you get so bent out of shape about it. Jul 02 13:57:06 you should plug in your Bacon Cape and visit http://beagleboard.org/Support/BoneScript/cape_bacon/ Jul 02 13:58:56 actually i don't have one of those Jul 02 14:00:35 poor kid Jul 02 14:08:34 Any idea why "parse-edid /sys/devices/ocp.2/4830e000.fb/drm/card0/card0-HDMI-A-1/edid" says following error ? Jul 02 14:08:40 parse-edid: IO error reading EDID Jul 02 14:08:59 monitor connected? Jul 02 14:09:16 yes, but I don't see nothing Jul 02 14:25:57 panto, agreed Jul 02 14:26:52 panto, and unless my memory fails me..that's not a permitted operation Jul 02 14:27:26 no it isn't Jul 02 14:28:25 * mdp looks at upstream Jul 02 14:28:31 what you are implying scares me Jul 02 14:28:59 mdp, oh, I'm a scary guy Jul 02 14:30:24 mdp: be carefull! he is greek! Jul 02 14:35:51 panto, which use of virt_to_phys() are you looking at? Jul 02 14:35:57 in the vring support? Jul 02 14:36:34 the sg_phys in virtio_ring.c Jul 02 14:37:35 note the weird hack in virtio_console.c when using the RPROC_SERIAL device Jul 02 14:40:12 yes, this is what I mentioned the other day about the need for rproc specific hacks in client drivers Jul 02 14:40:26 there is no need Jul 02 14:41:01 you can use normal kmalloc memory if you properly call dma_map/dma_unmap Jul 02 14:41:17 cause what you're really doing, is, dma to/from a device Jul 02 14:41:32 yes Jul 02 14:41:48 Good morning(/afternoon/evening); I was wondering if anyone has ever put the Beaglebone designs through EMC Jul 02 14:42:03 EMC? Jul 02 14:42:21 electromagnetic compatibility tests Jul 02 14:42:22 the magnetic or cnc variety? Jul 02 14:42:56 http://circuitco.com/support/index.php?title=BeagleBoneBlack#Regulatory_Compliance_Documents Jul 02 14:43:17 panto, I can only guess they didn't want streaming handling scattered about..or something like that Jul 02 14:43:33 compatible with what? Jul 02 14:43:43 I think they are utterly confused by something that's not like an x86 smp system Jul 02 14:44:12 evident by the way they casually drop the scatterlists after they submit them Jul 02 14:44:17 panto, it made it through the highly acclaimed kenrel review process ;) Jul 02 14:44:24 bah! Jul 02 14:44:29 maybe even the kernel review process ;) Jul 02 14:45:10 jkridner; We're looking at reproducing the system from board designs for embedded integration Jul 02 14:45:32 and trying to do due diligence on seeking out any existing EM testing that's been done on the design already Jul 02 14:46:59 MZXGiant: as said, FCC and CE Jul 02 14:47:05 MZXGiant: k, those docs should help you. Jul 02 14:47:28 panto, well, consider too that the rproc stuff is a second class citizen in virtio land Jul 02 14:47:38 it's not the original use case Jul 02 14:48:00 embedded is a second class citizen in the kernel land too Jul 02 14:49:26 that's such a 2002 sentiment ;) Jul 02 14:49:45 hehe :) Jul 02 14:49:45 only true if you aren't doing mobile ;) Jul 02 14:58:51 hi das_plague Jul 02 14:59:10 hi Mr das_plague Jul 02 14:59:30 die Plage Jul 02 14:59:54 test Jul 02 15:00:17 test failed Jul 02 15:02:20 test 2 Jul 02 15:03:14 welcome professor falken Jul 02 15:04:53 shall we play a game? Jul 02 15:06:50 how about a nice game of chess? Jul 02 15:07:06 no. let's play global thermonuclear war. Jul 02 15:07:19 I was hoping you'd say that Jul 02 15:07:24 rock on Jul 02 15:08:32 who should we nuke first? :) Jul 02 15:09:19 TII Jul 02 15:09:21 let's nuke the canadians Jul 02 15:09:39 they're so nice Jul 02 15:09:47 nuke america's hat?!? Jul 02 15:09:50 never Jul 02 15:09:57 * bradfa votes for canada too Jul 02 15:10:02 they had their day yesterday Jul 02 15:10:11 true that Jul 02 15:10:15 can we just nuke the hipsters? Jul 02 15:10:23 ok, portland it is Jul 02 15:10:26 take cover mranostay Jul 02 15:10:29 mranostay, stay still! Jul 02 15:10:31 do we get nuked after our day? Jul 02 15:10:39 bradfa: they were nuked before it was popular Jul 02 15:10:41 mdp, there is no USA day Jul 02 15:10:56 we can rebrand our other day, can't we? Jul 02 15:11:08 prism appreciation day? Jul 02 15:11:16 panto, we all appreciate the prisms Jul 02 15:11:26 PAD is not catchy enough Jul 02 15:11:29 or else... Jul 02 15:11:33 national prism appreciation day Jul 02 15:11:35 * bradfa hopes fbi / nsa / homeland security notices how patriotic he is Jul 02 15:11:53 bradfa, you've certainly made "a list" Jul 02 15:11:53 * bradfa waves at prisms Jul 02 15:12:04 mdp, top 10 ways to get on prism! Jul 02 15:12:14 10. be name mranostay Jul 02 15:12:23 9. shout "Troll!" on irc Jul 02 15:12:35 8. forget which day is Friday Jul 02 15:12:46 JIHAD! Jul 02 15:12:47 7. make a list of top 10 ways to do anything Jul 02 15:13:11 mdp, that's the double super secret code word! don't tell anyone! Jul 02 15:14:27 * bradfa wants to slap a unicorn Jul 02 15:14:35 stupid github, fix your internets! Jul 02 15:14:51 oh, maybe they did... Jul 02 15:15:25 bradfa: https://status.github.com/messages Jul 02 15:15:34 "We've resolved a connection exhaustion condition in our proxy infrastructure " Jul 02 15:15:44 koen, they must have switched to fex Jul 02 15:16:08 * bradfa should get back to work... Jul 02 15:22:32 bradfa, at least get back to sleeping under your desk Jul 02 15:23:59 * bradfa climbs back under desk Jul 02 15:32:01 bradfa: i take offense Jul 02 15:32:22 mranostay, I'll take defence, then Jul 02 15:32:35 * bradfa removes all your fence! Jul 02 15:32:46 is it friday yet? Jul 02 15:32:51 always Jul 02 15:33:08 I'm sitting on the fense on this one Jul 02 15:34:22 here it's friday till end of August Jul 02 15:34:29 or actually weekend Jul 02 15:36:33 * bradfa jumps with joy! twc now offers $35 15Mbps service! Jul 02 15:36:50 $30 for 3Mbps, $35 for 15 Mbps Jul 02 15:36:51 bradfa: no more ISDN link for you? Jul 02 15:36:57 mranostay, no! Jul 02 15:37:33 15/1 which isn't horrible Jul 02 15:38:04 * bradfa just ordered cable modem from amazon Jul 02 15:44:27 bradfa: did you pop a camera on that order as well? Jul 02 16:05:21 bradfa: They do? I'm paying $39.95 right now and thats supposed to be a discount rate (because I call and troll them) Jul 02 16:06:26 bradfa, as I've mentioned on g+ before..clearly you have some nicely competitive rates there ;) Jul 02 16:07:21 iirc we are at $45/$70/$100 for 15/30/50 downstream service Jul 02 16:07:44 there is also the new customer vs existing customer bs. Jul 02 16:07:50 there is that Jul 02 16:07:59 and their wonky first year pricing deals Jul 02 16:08:04 yeah Jul 02 16:08:06 promos Jul 02 16:09:28 tbh, the reliability is more important to me than the price since I work from home Jul 02 16:09:37 so no complaints there Jul 02 16:09:41 oh, yeah. true. Jul 02 16:11:10 mdp: plus its a tax write off Jul 02 16:13:23 well, as long as you properly only claim a portion of it...claiming all of it is an audit flag since most people use it for personal use as well ;) Jul 02 16:14:38 just like when you play the game of home office deductions and other utility costs Jul 02 16:18:29 * mdp wonders if prism is set up to feed these discussions into the IRS audit algorithms Jul 02 16:22:34 "If you are an employee, additional rules apply for claiming the home office deduction. For example, the regular and exclusive business use must be for the convenience of your employer." Jul 02 16:22:46 I'm not sure what that means Jul 02 16:23:07 it means that they must require you to have a home office Jul 02 16:23:17 if you have a home office because you want to and it's convenient for you, it's not a deduction Jul 02 16:23:30 you have to have a job that mandates having a home office as a condition of your employment Jul 02 16:23:44 Startups should fall under that category, IMO =\ Jul 02 16:23:51 they do Jul 02 16:24:01 I should take that deduction then Jul 02 16:24:11 I only spend 45/wk in the office Jul 02 16:24:21 the other 65 I spend at my home office Jul 02 16:25:52 Eh, point is going to be moot anyways. I take owner's equity for the LLC so my taxes are out of control for EOY Jul 02 16:31:11 finally my video wall is ready using the PI's : http://db.tt/DI2THaXE will be demoing @ media city bbc friday-saturday in case anyone wants to pop by or is from the uk ofcourse :P Jul 02 16:34:52 Hello there - I have search low and high for web help with issues surrounding connecting a webcam to the beagle bone black, when changing the resolution i get this error VIDIOC_S_FMT: failed: Input/output error. the Video0 can be seen in dev, though there is no output when using cheese. Jul 02 16:35:13 Any help? Jul 02 16:38:43 i can not find /dev/ttyUSB0 on Fedora 17 latest kernel. Jul 02 16:39:03 3.9.8-100.fc17.i686.PAE Jul 02 16:39:46 I had run script :mkudevrule.sh Jul 02 16:39:51 but no use. Jul 02 16:40:37 lsusb does not show the beaglebone usb device Jul 02 16:47:03 kelvin: i'm just debugging the same issue Jul 02 16:47:15 kelvin: just to check: you're trying to get serial console access Jul 02 16:47:25 kelvin: right? Jul 02 16:48:03 has anyone experienced this? it seems some (all?) boards lacks the fdti chip Jul 02 16:49:02 black doesn't have an ftdi chip Jul 02 16:49:17 after the board boots you'll get a ttyACM0 Jul 02 16:50:24 ezequielgarcia: I did not find the device node .Which tty* should i check ? Jul 02 16:50:26 panto: a ttyAMC0 on which port? USB client? Jul 02 16:50:44 on the host you connected the usb cable Jul 02 16:50:56 lsusb can not see bbb Jul 02 16:51:01 panto: the USB client? Jul 02 16:51:12 who is the usb client? Jul 02 16:51:25 there is a usb host (the pc) and the device (beaglebone) Jul 02 16:51:36 panto: right, USB device Jul 02 16:51:48 on the host side the device is named ttyACM0, on the device side it's ttyGS0 Jul 02 16:51:55 panto: but i want to boot an nfs kernel, so i'll use J1 right? Jul 02 16:52:13 the hardware rs232 port is best Jul 02 16:52:27 good enough for grandpa, good enough for me Jul 02 16:52:42 mdp, georgem, rates I'm seeing are new customer rates and are lower than I've seen in the past when I looked / did pay before Jul 02 16:53:03 we used to have 6/1 Mbps for $43/month Jul 02 16:53:07 at the old house Jul 02 16:53:14 panto: is that the J1 header? Jul 02 16:53:32 * ezequielgarcia looks at schematics but can't find it... Jul 02 16:53:39 yes Jul 02 16:54:02 you can't miss it, it's the single row 6 pin header Jul 02 16:54:07 panto: now apply that argument to other things, such as condoms Jul 02 16:55:15 panto: yeah, i see it on the board, not in the schematics :S Jul 02 16:55:43 and the one in the board is not numbered... Jul 02 16:56:09 I see a J1 right on top of it Jul 02 16:57:05 panto: on the schematics!?!? boy i must be blind! Jul 02 16:57:17 on the board Jul 02 16:57:27 I don't have the schematics handy Jul 02 16:57:41 the board header is obvious... but not numbered Jul 02 16:57:41 i.e. I'd rather not open them Jul 02 16:57:52 anyway, i just found it on schematics Jul 02 16:58:27 which is useless, because i need the numbers on the board! :( Jul 02 16:58:57 panto: can i hope the "dot" is the #1 pin? Jul 02 16:59:10 yes it is Jul 02 17:00:40 ok... here we go Jul 02 17:01:21 panto: success!!! :D great, thx Jul 02 17:01:33 np Jul 02 17:02:27 kelvin: if you need serial console access (e.g. to get to the bootloader) you need to use a FDTI or prolific cable (e.g. from Adafruit) connected to the J1 header Jul 02 17:02:28 Hi! I'm running Debian on my BBB and I finally managed to install XBMC on it, but to run it, it needs OpenGL and BBB supports OpenGL ES 2.0 So is it possible to get OpenGL 2.0 on BBB, if yes how? Jul 02 17:03:28 * panto needs coffee - this thing is killing me Jul 02 17:03:55 ok, cool. i have to admit i prefer when boards come with the lil' usb for console access... but... Jul 02 17:04:16 the little usb is expensive Jul 02 17:05:33 usb is also horrible Jul 02 17:06:02 no, usb is _unreliable_ Jul 02 17:06:19 fair enough Jul 02 17:06:43 u is for unreliable Jul 02 17:06:53 s is for s****y Jul 02 17:07:02 b is for braindead Jul 02 17:07:03 I was going to say satanic Jul 02 17:07:12 I'm more scatological Jul 02 17:10:33 panto: i dunno.... i just *love* to plug the usb and magically boot test my boards... Jul 02 17:10:47 panto: sure, it's a huge overkill... Jul 02 17:15:30 does anyone knows if there's anyway to do a "saveenv" on the u-boot that is on the emmc Jul 02 17:28:41 bradfa, that sounds roughly like what my regional unit had when we first moved here. it's definitely gotten better. I sometimes wish for something greater than 5Mbps upstream, but not often enough to worry about it Jul 02 17:29:06 mdp, I'd love more upstream but can't justify the cost Jul 02 17:29:19 if I ever end up working at home it'll be easy to justify though Jul 02 17:31:44 bradfa, it's not often that I need to scp a kernel git repo elsewhere..and normally I can do everything on that remote server so I shouldn't have to anyway Jul 02 17:31:53 the use cases are slim at best Jul 02 17:41:32 andypugh: which branch are you working off, master? Jul 02 17:41:35 No one knows a solution to my problem? :( Jul 02 17:46:31 andry> there is the 'desktop' version of OpenGL and the stripped down OpenGL ES for embedded systems, phones, and the such. Jul 02 17:47:33 andry> it sounds like you need to look for or attempt to compile (if supported) a desktop version of OpenGL. Jul 02 17:49:50 he's trying to support an existing 3d app on the bbb, if it doesn't embedded GL support of some support he'd have to write an egl layer for it Jul 02 17:51:51 hi ka6sox Jul 02 17:51:58 maybe he could benefit from another distro that already has an EGL. Isn't that the case with Android? Jul 02 17:52:07 mourning panto Jul 02 17:52:15 mourning indeed Jul 02 17:55:37 mranostay, go make fun of my pcmcia on g+ Jul 02 17:55:37 Today the workers outside are tearing into my walls...time for a Road Trip! Jul 02 17:55:50 mranostay, when it arrives I'll take fuzzy pics for you Jul 02 17:56:09 bradfa, did you see my recent fuzzy picture? Jul 02 17:57:48 ka6sox, something fuzzy indeed! Jul 02 17:58:36 ok, I just noticed that g+ posts aren't in order any more... Jul 02 17:58:38 wtf Jul 02 17:58:48 they are in google(tm) order Jul 02 17:58:52 move along citizen Jul 02 17:59:10 even facebook is mostly in order... Jul 02 18:03:03 <_Sy_> Hello, I'd like to enable serial communication between two beaglebone black's without loosing USB or ethernet, which UART should I use? Jul 02 18:03:40 _Sy_, any except 0 or 3 Jul 02 18:04:13 <_Sy_> ok, 1, 2, 4 or 5 then ? Jul 02 18:04:45 _Sy_, not every UART is routed to the connectors Jul 02 18:04:57 UART3 is not possible Jul 02 18:05:03 any other will work Jul 02 18:05:43 _Sy_, 0 will work, too, if you don't mind not having the ability to use it to log in Jul 02 18:05:45 <_Sy_> Looking at the PDF now it seems 2, 1, 4 and 5 are available on connector...how do I get these to appear as devices in the /dev folder? Jul 02 18:06:21 with a recent enough kernel: Jul 02 18:06:34 echo BB-UART2 > /sys/devices/bone_capemgr*/slots Jul 02 18:06:39 <_Sy_> I should be bang up to date on Angstrom builds Jul 02 18:06:50 My brand-new Beagleboard-xM, connected to brand-new LCD C7 boots up into a reversed gnome desktop. Touch screen also doesn't work. Anyone else experience this? Jul 02 18:07:12 note the ttyOx number is not going to be related to the UART # Jul 02 18:07:29 it's 0, 1, in order of appearance Jul 02 18:07:46 cfo216, try cold power powerup Jul 02 18:08:07 thanx Jul 02 18:08:26 <_Sy_> ok there are a lot of tty devices, how do I identify which one is the one to use for example UART2? Jul 02 18:08:49 the new one that appears Jul 02 18:09:12 so if you only have the standard ttyO0, enabling a second one will always be ttyO1 Jul 02 18:09:18 I tried that. Same issue. Jul 02 18:09:48 send an email to the list Jul 02 18:09:58 cfo216: what do you mean by reversed, colored like a negative... left is right, top is bottom, etc? Jul 02 18:10:04 <_Sy_> ah...I now have tty02 Jul 02 18:10:24 <_Sy_> ty Jul 02 18:10:56 i have a serial port connected to the db9 and all i see is giberish. setting 115200-8-N-1. Not sure if that's the correct setting though. Also tried at 9600 Jul 02 18:11:07 * panto pandora's feed appropriately plays 'crazy train' Jul 02 18:11:24 115200 is the right baud rate Jul 02 18:11:53 115200 is correct.. do you have all flow control disabled? Jul 02 18:12:40 parity and flow control are none Jul 02 18:12:47 using gtkterm Jul 02 18:13:26 do you get garbage with the LCD disconnected too? Jul 02 18:13:27 SoCo_cpp Thanks, but how I am supposed to do that? I'm really new to linux Jul 02 18:13:59 didn't try that... will do... Jul 02 18:16:09 <_Sy_> Does UART2 have CTSN and RTSN, I don't see them on the connector in the PDF ? Jul 02 18:18:09 BxM is still displaying garbage, even when disconnected to LCD C7 Jul 02 18:18:14 _Sy_, can't remember, but not all uarts have the full set of h/w flow control signal Jul 02 18:18:24 something is bad there Jul 02 18:18:54 just to be sure, use screen: $ sudo screen /dev/ttyFOO 115200 Jul 02 18:18:57 <_Sy_> It looks like only UART4 and UART5 have everything. Jul 02 18:19:02 reflash the SD Card maybe fix it? Jul 02 18:19:08 doesn't hurt Jul 02 18:19:20 I'll try that. Like you said. Can't hurt. Jul 02 18:20:47 cfo216: did you restart with the terminal ready to capture i/o? Jul 02 18:21:18 <_Sy_> Sorry for all the nooby questions...I've now done this: Jul 02 18:21:18 <_Sy_> echo BB-UART4 > /sys/devices/bone_capemgr*/slots Jul 02 18:21:27 <_Sy_> and now I get ttyO4 Jul 02 18:21:38 <_Sy_> how can I ensure this is done on boot? Jul 02 18:21:39 that's cause you didn't unload the other capes Jul 02 18:21:43 sometimes starting the terminal to a running system will cause sync errors like you're seeing Jul 02 18:22:02 add the following to the optargs u-boot environment variable in uEnv.txt Jul 02 18:22:04 just got the board today... don't know what I'm doing withit. Just hoped it would work out of the box... not my luck, as usual. Jul 02 18:22:10 capemgr.enable_partno=BB-UART4 Jul 02 18:22:22 cfo216, it usually does Jul 02 18:23:01 <_Sy_> where do I put that? Jul 02 18:23:18 there's uEnv.txt file in the fat partition Jul 02 18:23:23 panto, ...goes bad, or works. LOL Jul 02 18:23:31 seen that. Jul 02 18:23:35 does uboot's page have some good docs for uEnv.txt? Jul 02 18:23:41 such is life Jul 02 18:24:03 <_Sy_> I don't have a uboot folder, only /boot/uEnv.txt Jul 02 18:24:06 I want to manage booting between angstrom on emmc and arch on sd without hitting the usr button Jul 02 18:25:08 right, /boot is the fat boot partition Jul 02 18:25:27 flrichar, hack your u-boot environment Jul 02 18:26:30 bad serial cable... bad, bad cable! Jul 02 18:26:38 I have a console !!! Jul 02 18:26:40 that explains it Jul 02 18:26:45 <_Sy_> I've edited my uEnv.txt which is in /boot, I've added: capemgr.enable_partno=BB-UART4 Jul 02 18:27:10 you have to add it in the line which contains optargs= Jul 02 18:27:30 <_Sy_> ok, will do when it comes back. Jul 02 18:27:37 a google search about u-boot and it's environment might help Jul 02 18:28:25 any ideas about the LCD? I think the X config is bass ackwards, or worse someone wired it wrong. which would really suck. Jul 02 18:29:23 cfo216, it shouldn't do that Jul 02 18:30:01 Angstrom 2010.7-test-20110220 beagleboard ttyS2 is what it boots into... I think someone at the factory forgot to put the correct SD card in the unit. Jul 02 18:30:34 root@beagleboard:~# uname -a Linux beagleboard 2.6.32 #3 PREEMPT Thu Mar 17 08:56:19 CET 2011 armv7l unknown Jul 02 18:30:55 I'll put a new OS on it and see what happens. Jul 02 18:30:59 Thanks for all your help panto. Jul 02 18:31:29 cfo216, yep, that's kinda old Jul 02 18:32:23 kind of makes me mad. It a Rev C2 board. It still has "new board" aroma. LOL Jul 02 18:33:10 keep calm and carry on Jul 02 18:33:19 worse things have happened Jul 02 18:33:21 will do. Thanks!! Jul 02 18:33:38 <_Sy_> This is the contents of uEnv.txt, optargs=run_hardware_tests quiet capemgr.enable_partno=BB-UART4 Jul 02 18:33:47 <_Sy_> Just restarted, it didn't work. Jul 02 18:35:01 what does the dmesg output say Jul 02 18:37:37 <_Sy_> what exactly am I looking for it looks like the same thing is said over and over. Jul 02 18:38:10 dmesg | capemgr Jul 02 18:38:42 <_Sy_> capemgr: command not found Jul 02 18:38:50 err, dmesg | grep capemgr Jul 02 18:39:15 <_Sy_> did that nothing is displayed Jul 02 18:39:27 err, that can't be Jul 02 18:39:33 what kind of kernel are you using? Jul 02 18:39:39 <_Sy_> dmesg | grep capemgr Jul 02 18:39:46 <_Sy_> Angstrom Jul 02 18:39:58 ok, paste the whole dmesg output in pastebin or something Jul 02 18:40:01 got to go eat Jul 02 18:40:04 I'll see it later Jul 02 18:40:08 <_Sy_> ok, ty Jul 02 18:41:38 <_Sy_> http://pastebin.com/3eV2j3cy Jul 02 18:44:04 <_Sy_> g2g, daughter needs computer, I'll be back l8r Jul 02 19:34:09 panto: did you try the earlyprintk stuff in beaglebone black Jul 02 19:34:11 ??? Jul 02 19:36:32 So is robertCnelson maintaining armhf.com? Jul 02 19:38:58 ezequielgarcia, yes Jul 02 19:39:05 it should work Jul 02 19:39:11 why do you need it? Jul 02 19:39:25 i'm not sure which uart should i config in CONFIG_DEBUG_LL Jul 02 19:39:36 it's only for crashes that happen very early in the boot sequence Jul 02 19:39:40 am33xx Jul 02 19:39:47 panto: i'm building mainline stuff, and it's crashing very early := Jul 02 19:39:50 :) Jul 02 19:41:00 ok, i'll try again with that option. it must be misconfig... Jul 02 19:41:11 ezequielgarcia, why don't you wait until I push my mainline tree Jul 02 19:41:36 probably early tomorrow Jul 02 19:41:40 panto: that'd be cool, you don't happen to have it in some github? Jul 02 19:41:47 yes, it will be on github Jul 02 19:41:53 or some git repo somewhere...? Jul 02 19:42:08 panto: i was playing with the same idea.... Jul 02 19:42:09 I'm just too tired to do the branching dance this late Jul 02 19:42:16 panto: sure, np. Jul 02 19:42:19 will do it first thing tomorrow Jul 02 19:42:24 so hold your horses Jul 02 19:42:31 there's lots of work to do on 3.10+ Jul 02 19:42:46 panto: hm, it does not even boot? Jul 02 19:42:58 not even show some early panic? Jul 02 19:43:22 it boots and a lot of stuff works Jul 02 19:43:24 just not all of it Jul 02 19:43:36 hint, you need extra patches for that Jul 02 19:45:12 i mean: the v3.10 tag, boots? with no patches? Jul 02 19:45:25 boots over root nfs Jul 02 19:45:53 anyway, have to go now Jul 02 19:45:54 bbt Jul 02 19:46:15 sure, np Jul 02 19:47:13 panto: thanks! Jul 02 19:48:33 *sigh* am335x is the least of my problems right now. Wish we could EOL all of our old products and refresh them with it. Maintaining support for a product with a 10 year old ARM CPU will drive you insane. Jul 02 20:01:05 Is it possible to use an OpenGL ES 2.0 emulator on the BBB? Jul 02 20:04:49 does the OS you're using not have the ogles libraries? Jul 02 20:05:57 Well not a single porgram can detect it so I think it doesn't have. BTW I use the debian image from elinux.org Jul 02 20:06:01 *program Jul 02 20:08:40 So? Jul 02 20:11:28 Or how do I get the OpenGL Drivers for the BBB on Debian? Jul 02 20:14:14 georgem, which 10 year old ARM? Jul 02 20:14:30 bradfa: IXP425 Jul 02 20:14:47 ooo Jul 02 20:14:59 fancy Jul 02 20:15:29 pci! Jul 02 20:15:41 back in the day it wasn't too bad Jul 02 20:15:42 yeah... Jul 02 20:15:56 still probably wouldn't be a bad SoC if the price was right Jul 02 20:16:20 it doesn't have enough address lines to address more than 32MiB of NOR flash :( Jul 02 20:16:31 andry_: have you search the repos for egl or gles? Jul 02 20:16:35 georgem, 32 MiB is decent Jul 02 20:17:07 bradfa: yeah, it's decent but add 10 years of feature creep... Jul 02 20:17:53 georgem, I hear ya Jul 02 20:18:17 georgem, don't wish for am335x-ing all your things, though, it's not all it's cracked up to be Jul 02 20:19:33 bradfa: how so? Jul 02 20:20:02 georgem, mainline is still a work in progress, 1.5 years after release of the thing Jul 02 20:20:17 TI's not stellar at that, yet Jul 02 20:20:25 bradfa: yeah... thats true. bit disappointed with the way ti handled things Jul 02 20:20:46 georgem, and the complexity is not low for the chip Jul 02 20:21:03 the price might be right, for some, though Jul 02 20:21:04 thurgood: actually not. Which should I install? Jul 02 20:21:35 georgem, I need to get to trying out my atmel sama5 kit, I'm excited to see where that goes Jul 02 20:22:54 bradfa: sama5 looks pretty cool. its nice you can get two ethernet interfaces with am335x though Jul 02 20:23:06 georgem, sama5d35 has dual ethernet Jul 02 20:23:22 but no lcd controller Jul 02 20:23:25 bradfa: oh, in that case thats awesome. Jul 02 20:23:34 andry_: search for egl and gles and pastebin the results Jul 02 20:23:35 Spirilis: http://electrotap.com/2004/11/01/op-amps-part-1-scaling-sensor-voltages/ is the basis for an op amp circuit. Lots of distractions and will get to it later today or tomorrow. Jul 02 20:23:37 a5d35 is the one I'm interested in most Jul 02 20:24:34 * bradfa doesn't need fancy guis Jul 02 20:24:37 mdp, bradfa, av500, koen, ka6sox, panto and all: new version of pasm is at https://github.com/beagleboard/am335x_pru_package Jul 02 20:24:43 bradfa: How is mainline support? Jul 02 20:24:55 georgem, dunno yet, but will know next week when I get to test it Jul 02 20:25:09 jkridner: nice, taking a peek Jul 02 20:25:28 georgem, promising -> https://plus.google.com/108506657199236487651/posts/4KEN41gGYpV Jul 02 20:25:42 jkridner, cool Jul 02 20:27:19 bradfa: yeah, that looks pretty good. I don't know much about the Cortex A5 yet, does it perform similarly clock-to-clock with an A8? Jul 02 20:27:43 georgem, I believe it's similar but haven't done the research yet myself either Jul 02 20:31:14 thurgood: The search results for "egl" http://pastebin.com/9gHWQJZM and for "gles" http://pastebin.com/dJd4s8zh Jul 02 20:31:58 georgem, floating point is optional like arm9, unlike cortex-a8 which requires at least vfp (forget which level) Jul 02 20:32:10 so if floats are important... Jul 02 20:32:25 bradfa: whatever floats your boat Jul 02 20:32:33 mranostay, my boat sinks Jul 02 20:32:39 bradfa: on ixp425 we're using soft-float Jul 02 20:32:49 georgem, I'm sorry to hear that Jul 02 20:32:51 :) Jul 02 20:33:40 georgem, in order execution for cortex-a5 Jul 02 20:34:13 slightly lower dmips/mhz according to spec Jul 02 20:37:49 jkridner|work: taking a look at those, I've seen those types of schematics before. One thing I'm not quite sure is what you do when your input voltage range is *higher* than the output... (voltage divider, with a voltage-follower to adapt impedances?) Jul 02 20:38:34 Eventually would like to replace the intel atom based product I have with an ARM. Would need something pretty quick to do that... and have PCIe Jul 02 20:39:11 georgem, higher end ti parts have pcie Jul 02 20:39:22 georgem, or you could try to wrangle a datasheet out of marvell Jul 02 20:39:55 I think freescale has some, too, but I'm not that familiar with their parts beyond some powerpc and low end imx Jul 02 20:40:08 iMX 6 looks pretty interesting Jul 02 20:40:36 georgem, yes, but I'm scared of freescale Jul 02 20:40:47 yeah, me too Jul 02 20:42:50 I'm scared of everything these days. If you need any kind of performance out of a display for instance pretty much everyone has something PowerVR based and the closed source crap locks you into certain versions of xorg and kernel. Jul 02 20:48:48 ST has some parts with PCIe too Jul 02 20:49:21 would be interesting to see a solution that paired an ARM with PCIe with an embedded AMD GPU (which has open source drivers) Jul 02 20:50:31 chandler: don't the ARMv8 offerings from AMD have that? Jul 02 20:51:27 chandler: that would be cool. last time I checked a few years ago AMD's embedded GPUs didn't have anything that would work for industrial temp range. Jul 02 20:52:44 cheap usb-ttl-serial ftw.. none of the pins are labeled right Jul 02 20:53:19 ds2: no such beast yet, so it's all speculative Jul 02 20:55:58 georgem: huh. I guess when I saw "embedded" I assumed that it was specced for industrial temperature range. I wonder what the point is otherwise Jul 02 20:56:55 chandler: all kind of crap like kiosks, gambling machines, in-wall display sort of things Jul 02 20:58:36 the question I was really asking is "why is this better than the COTS parts". all I can determine is (a) 5 year availability, for what that's worth, and (b) they probably won't talk to you about !embedded parts unless you hit volume targets or are in China Jul 02 20:59:49 chandler: A lot of COTS stuff barely works at room temp without overheating :) Jul 02 21:00:31 in this case their "embedded" parts seem to be COTS parts from 2-4 generations ago Jul 02 21:00:44 yeah, I wasn't too impressed last time I looked Jul 02 21:00:49 it's probably just a way to sell off excess inventory and ream the people who buy from Avnet Jul 02 21:00:55 probably Jul 02 21:02:24 <_Sy_> Hi Panto are you here? Jul 02 21:02:54 it'll be interesting to see what silverthorne does for this market, since intel's finally ditching powervr for a cut down version of their own HD graphics Jul 02 21:03:35 noobtime.. I'm trying to enable a cape at boot with optargs=capemgr.enable_partno=... but it's not working. is the optargs some kind of builtin that's always passed to the kernel or do I need to use the variable when jumping into kernel? Jul 02 21:05:48 <_Sy_> @vaizki, me2... Jul 02 21:06:26 <_Sy_> Have you tried adding it to uEnv.txt in /media/BEAGLEBONE/uEnv.txt, thats my next port of call. Jul 02 21:07:08 well that's where I added it. well not exactly there as I'm using Arch and it doesn't mount it there. Jul 02 21:07:19 thurgood ? Jul 02 21:07:20 hmm this is weird.. Jul 02 21:07:40 [ 0.861656] Waiting for root device /dev/mmcblk0p2...

Jul 02 21:09:04 oh.. hmm.. actually it tries to load the cape firmware before loading the emmc driver :O Jul 02 21:09:13 that MIGHT have something to do with it Jul 02 21:09:41 thurgood: Oh okay Jul 02 21:09:55 or something. this is weird. need to investigate further I guess Jul 02 21:12:49 _sy_ did you work out how do to your serial heart beat thing? Jul 02 21:13:16 if worse comes to worse you can make the packages by downloading the gles sdk from TI Jul 02 21:13:19 <_Sy_> the actual heartbeat is pretty simple, its enabling the UART4 in the boot that I'm struggling with Jul 02 21:15:15 sy, http://blog.pignology.net/2013/05/getting-uart2-devttyo1-working-on.html Jul 02 21:15:40 just put it in the uEnv.txt in /media/BEAGLEBONE/ as you thought Jul 02 21:16:12 <_Sy_> will give it a go, ty Jul 02 21:16:29 arch doesn't have any BB-* stuff in /lib/firmware.. Jul 02 21:16:32 hmmh Jul 02 21:17:08 andry_: http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide Jul 02 21:19:14 <_Sy_> Have created a uEnv.txt in /media/BEAGLEBONE with the following content: Jul 02 21:19:14 <_Sy_> optargs=quiet capemgr.enable_partno=BB-UART4 Jul 02 21:20:16 it wasn't there before? Jul 02 21:20:21 <_Sy_> no Jul 02 21:20:27 completely empty dir? Jul 02 21:20:40 <_Sy_> it wasn't empty, but it didn't have uEnv.txt Jul 02 21:21:11 are you booting from internal eMMC? Jul 02 21:21:27 <_Sy_> yes Jul 02 21:21:41 did the directory have "MLO" and "u-boot.img" in it? Jul 02 21:22:53 <_Sy_> no, sorry, /media/BEAGLEBONE/ is empty Jul 02 21:23:07 ok probably not mounted then Jul 02 21:23:22 is that your primary partition on your SD card? Jul 02 21:24:06 remove the uEnv.txt and type: mount /dev/mmcblk0p1 /media/BEAGLEBONE Jul 02 21:24:07 <_Sy_> I don't have an SD card in, I am booting from eMMC and I also have a 32GB USB stick in, which is empty, but mounted as /usbstick Jul 02 21:24:38 if the dir is empty the vfat filesystem isn't mounted Jul 02 21:24:57 you can ofcourse check with "lsblk" for example if mmcblk0p1 is mounted anywhere Jul 02 21:25:10 p2 = / (root) Jul 02 21:25:21 <_Sy_> NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT Jul 02 21:25:21 <_Sy_> sda 8:0 1 29.8G 0 disk Jul 02 21:25:21 <_Sy_> |-sda1 8:1 1 70.6M 0 part /mnt/usbstick Jul 02 21:25:21 <_Sy_> `-sda2 8:2 1 1.7G 0 part Jul 02 21:25:21 <_Sy_> mmcblk0boot0 179:8 0 1M 1 disk Jul 02 21:25:21 <_Sy_> mmcblk0boot1 179:16 0 1M 1 disk Jul 02 21:25:23 <_Sy_> mmcblk0 179:0 0 1.8G 0 disk Jul 02 21:25:27 <_Sy_> |-mmcblk0p1 179:1 0 70.6M 0 part Jul 02 21:25:29 <_Sy_> `-mmcblk0p2 179:2 0 1.7G 0 part / Jul 02 21:25:44 yea, mmcblk0p1 isn't mounted. mount it with the command I gave you Jul 02 21:26:34 <_Sy_> ok, ty, done that, but why wouldn't it be mounted? Jul 02 21:27:13 you may not have automounting enabled Jul 02 21:27:28 now you can go and edit the uEnv.txt there Jul 02 21:27:52 <_Sy_> Isn't it mounted as part of the build? My uEnv.txt now reads: optargs=quiet drm.debug=7 capemgr.enable_partno=BB-UART4 Jul 02 21:28:06 you don't need to have that partition mounted for anything else than editing uEnv.txt Jul 02 21:28:14 mounted as part of the build? what? Jul 02 21:28:31 <_Sy_> I will restart now. Jul 02 21:30:42 when the board starts up the boot rom will look for a FAT partition on the eMMC (or uSD), then load and execute "MLO" from there. MLO is just a stub to load u-boot (from u-boot.img) which reads in uEnv.txt from there and then finds the linux kernel on p2 giving your optargs to the kerneö Jul 02 21:30:52 <_Sy_> Excellent, another problem solved, tty04 now present in /dev/ Jul 02 21:31:48 so at no point in the boot is the p1 partition really "mounted", the rom and uboot just use it in read-only fashion to get your kernel up with the right options Jul 02 21:31:59 <_Sy_> Now just got to connect the two boards together, cross over tx and rx and hopefully communications will flow :) Jul 02 21:32:00 MLO is a little bit more then a stub Jul 02 21:34:35 <_Sy_> Going to write a node.js lib sometime this week....the idea being to see how responsive it is...when the hardware detects an interrupt I will fire an event and see if the node.js code can keep up. Jul 02 21:36:19 <_Sy_> Have to leave now...ty for help Jul 02 21:57:16 I am struggling to get the right source code for xloader(MLO) & u-boot for "BEAGLE BONE BLACK". I tried the instruction on "http://elinux.org/BeagleBoard#U-Boot", but with this built image, I dont see the traces coming up onUART :( Can some one please point me to right code base ; many thanks in advance Jul 02 22:00:43 what are you using for the make config variable? Jul 02 22:08:02 hi everyone, some has ever met trouble while initializing an RS485 cape? Jul 02 22:08:52 I'm guessing you did Jul 02 22:09:11 Is the 485 cape connected serial TTL? Jul 02 22:09:19 no, but I've had trouble with his brother RS422 Jul 02 22:09:44 Or does it have a UART on it too? Jul 02 22:10:00 * mru suggests using R2D2 Jul 02 22:10:40 it should have a built in uart: a dedicated chip for rs485 Jul 02 22:11:02 These droids aren't the droid you're looking for. Jul 02 22:11:42 d'oh, I need those droids asap! :D Jul 02 22:13:11 btw, the thing I can't understand is why, the cape is recognized but not initialized by the system, while a RS232 cape is initialized with no problem Jul 02 22:13:12 Zuya78: What do you mean by "initializing an RS485 cape" Jul 02 22:13:19 hrm Jul 02 22:13:40 hrm, the hypothetical reference manual Jul 02 22:13:43 sounds like its not finding its I2c chip Jul 02 22:14:16 initialize is the found in dmesg output Jul 02 22:15:44 while debugging i typed dmesg | grep tty and the resultant output says that the cape (the circuitco rs485 cape) is recognized, its eeprom is found Jul 02 22:16:01 oh... well... what is the problem? Jul 02 22:16:14 at the right address but the cape is not initialized Jul 02 22:16:30 it says "cape is not initialized"? Jul 02 22:17:20 There are a couple of pins to change with pinctl, other than that there is nothing to initialize. Jul 02 22:17:29 Which kernel are you using? Jul 02 22:18:16 something similar, maybe "not initializing the cape". At the moment I don't remember exactly, it's a trouble at work and now i'm at home near to goin' to bed :D Jul 02 22:18:26 the kernel is 3.2.10 Jul 02 22:18:37 oh... thats pretty old. You should upgrade Jul 02 22:18:45 angrstrom Jul 02 22:19:12 yeah. get a newer version of angstrom Jul 02 22:19:33 well, i can try Jul 02 22:20:53 but for what i read on various internet pages rs485 is supported by kernel sinc 2.35, updating kernel wasn't my first idea Jul 02 22:21:17 one sec... Jul 02 22:22:18 I also tried to post this trouble on the the official google group for beagle bone but it hasn't been approved and published yet... Jul 02 22:23:17 well... maybe there is someway to get it to work but I don't even know how to mess with the pin selection stuff on 3.2. If you had a 3.8 kernel I could tell you how to check to make sure the uart pins are in the correct mode Jul 02 22:25:35 Zuya78: Can you find any evidence suggesting that the rs485 cape worked for anyone with that version of Angstrom? Jul 02 22:26:04 if it doesn't take a lot of your time i'll be glad to read you suggestion, maybe could work also with 3.2 or i could update kernel Jul 02 22:26:43 the cape is an old board, developed when beagleboard was working with older kernel version Jul 02 22:27:28 Does this directory exist? /sys/kernel/debug/pinctrl/44e10800.pinmux Jul 02 22:28:49 by now i don't remember, tomorrow morning (i'm in italy and it's night now) at work, i'll check Jul 02 22:28:55 Oh crap. Now you've confused me. I was thinking you meant the beaglebone cape. Jul 02 22:29:09 yes the beaglebone cape Jul 02 22:29:30 ok. beaglebone not beagleboard, right Jul 02 22:30:10 ok. yeah. will be better for me to check at work tomorrow too Jul 02 22:30:58 and... I actually have one of those capes at work Jul 02 22:31:42 by now i noted the directory you told me to check Jul 02 22:32:33 thank a lot, hope to find you tomorrow :D Jul 02 22:33:03 hoping also that my post in the google discussion group will be approved and published Jul 02 22:35:46 jkridner|work: hmm, I think I got it. 3V3 voltage-follower on the signal input, output of that opamp drives a voltage divider with decently low impedance (e.g. 10K+12K) going into AIN. Jul 02 23:19:34 new beaglebone user here in need of help Jul 02 23:20:11 with? Jul 02 23:20:48 analog inputs on the beaglebone ain0 through ain 6.....trying to get a reading from it Jul 02 23:21:26 what are you trying? Jul 02 23:22:57 in p9 header pin 40 which is "ain1" ...i put a green led which creates voltage from 0 to 1.5v depending on the light levels....but i "cat" the valve....all i see is the max number then "root@beaglebone" after Jul 02 23:23:27 even when i cover the led its still max Jul 02 23:23:50 connect a 1k resistor to ground. Jul 02 23:23:57 what do you measure? Jul 02 23:24:10 what mode are you using the LED in? Jul 02 23:24:18 LED as photodiode is in general a terrible idea Jul 02 23:24:33 it does not work with all sorts of led Jul 02 23:25:29 analog inputs....cant change the mode ...they appaerntly are just in one mode...and a green led does make voltage....connect resistor from negative on led to ground? Jul 02 23:26:21 no, just to ground and the input pin. does it read zero Jul 02 23:26:39 ok one sec Jul 02 23:26:56 have you actually measured the voltage on this LED? Jul 02 23:28:51 you can use LED as a photodiode or as a photovoltiac cell Jul 02 23:28:59 yes ....the resistor did work and AIN1 ...i did the cat valvue on AIN2 and got readings ...yes it did go to zero... Jul 02 23:29:41 most likely you need to buffer it or have a impedence conversion Jul 02 23:30:18 you can use a green led as a photocell...it will read 1.5v in max light conditions and lower as the lights dim **** BEGIN LOGGING AT Wed Jul 03 01:02:05 2013 Jul 03 01:37:32 he didn't stick around long Jul 03 01:37:43 Not at all. haha Jul 03 01:38:00 guess he saw me here and figured I might have another question about the BCC Jul 03 01:40:18 i'm working on BCC also Jul 03 01:40:26 Really? Cool. Jul 03 01:41:04 yeah where are the newZs Jul 03 01:41:23 ka6sox: do you have an e-mail I could send you those issues I found with that dts file? I still have a warning output and I'm not wise enough to figure out what it is, and if it's acceptable. Jul 03 01:42:05 what do i need off github, just these two? bcc_lib bcc_software Jul 03 01:42:15 I got my beaglebone black working it's ass off. I've just been using it as a tiny low power server but now I'm thinking of getting another to actually use the pins and make fun projects. Jul 03 01:42:45 mastiff: are you planning on getting it going tonight? I'll be around and just went through the setup the other night, so I should be able to help you through Jul 03 01:43:31 Basically, you'll need to grab the lib and software, get the eeprom code going, flash the eeprom, build the bcc_tool, use it to flash the fpga, and go to town :D Jul 03 01:43:42 ooh... you'll also need to download the dts, and build a device tree blob Jul 03 01:43:49 yeah, that sounds good, i've check for shorts so the board is good hopefully Jul 03 01:43:57 i'm using BBB Jul 03 01:44:08 you also? Jul 03 01:44:12 you should be able to use i2c detect (i used that as well) and you'll be able to see it Jul 03 01:44:31 mine was running debian Jul 03 01:44:51 i built the spi DT previously on my other BBB Jul 03 01:45:11 Then you understand it then :D Jul 03 01:45:29 I had a harder time because debian's dtc compiler needed to be patched Jul 03 01:45:35 so I know what's going on there, not sure how to initialize the BCC with the eeprom after they are connected Jul 03 01:45:52 on the bcc software page, go into the eeprom folder, it has the instructions Jul 03 01:45:55 VERY simple Jul 03 01:45:58 like 2-3 commands haha Jul 03 01:46:09 i was using angstrom previously, but now debian Jul 03 01:46:50 if you've just switched to debian, you'll have to patch debian's dtc compiler... I've got the link around here somewhere Jul 03 01:49:57 jmoyerman, sure Jul 03 01:53:23 ka6sox, you work with nooks also? Jul 03 01:53:51 yes Jul 03 01:54:00 saw something about that when I was grabbing bcc stuff off gethub Jul 03 01:54:56 :) Jul 03 01:55:07 i need some kind of nook to use for remote inteface in the sunlight for shell access to bbb Jul 03 01:55:19 what do you like for that? Jul 03 01:55:59 isn't the nook android based? Jul 03 01:56:25 the kindle is linux Jul 03 01:56:28 i had a root shell on it Jul 03 01:57:24 yeah I wanna use a nook for shell access from cockpit of my sailboat to bbbs inside the boat Jul 03 01:57:49 Interesting... What will you be using the BBB for? Jul 03 01:58:39 i think either android rooted or installing debian etc is the way to go, but it also depends on the chartplotter program as well Jul 03 01:59:16 Ugh... this is what happens when you get a software developer writing Verilog. Jul 03 01:59:42 I wanna use it in bright sunlight for console access for reading and programming, and also for displaying nautical charts Jul 03 02:01:24 openCPN is good charting for linux, and i use mxmariner on android, so I'm interested in getting one of those to display nicely on a nook Jul 03 02:14:34 That sounds like a good idea. Jul 03 02:16:08 eInk is the one thing I don't have haha Jul 03 02:30:58 what would I need to supply a vendor that doesn't want to supply their driver source but will compile a custom module for me? Jul 03 02:31:38 thurgood: can't they give you a library to link against atleast? Jul 03 02:32:16 a library in the kernel mod... dind't even know that was possible Jul 03 02:33:05 wait... driver source... duh lol.
