**** BEGIN LOGGING AT Thu Oct 31 02:59:58 2013 Oct 31 05:28:49 i interfaced 5.7 inch LCD, with beagle bone black with 16bpp mode, am getting all the signal likk Clock, HSYNC, VSYNC properly except Enable Oct 31 05:28:53 how do I enable second uart on beagle bone black Oct 31 06:39:39 hiiiii Oct 31 12:09:59 Hey. Oct 31 12:17:42 I encountered a silly thing on eBay. Someone selling a 4GB class 4 microSD with "pre-installed Ubuntu for BeagleBone" for $20. If the seller managed to come up with such a devious plan to get rich, surely he should also realize he picked the wrong audience for overpriced SD cards? Oct 31 12:20:03 ZiNC, I'm pretty sure he's picked exactly the right audience, eBay is full of this type of stuff Oct 31 12:20:19 The right audience? Oct 31 12:20:57 ZiNC: it works for rpi Oct 31 12:21:04 and to be honest, Im glad that exists Oct 31 12:21:07 What do you mean? Oct 31 12:21:32 Can you imagine anyone who's interested in BB who'd buy that SD for $20? Oct 31 12:21:43 yes Oct 31 12:21:47 Why? Oct 31 12:24:37 because there are many people who cannot build their own sd card image Oct 31 12:24:54 So what are they doing having a BB? Oct 31 12:25:17 same question for rpi Oct 31 12:25:24 yet the cards sell Oct 31 12:25:27 not all people are alike Oct 31 12:26:22 I'd think you'd want to learn to use the keyboard, mouse, and a search engine, before you start playing with electronics and programming. Oct 31 12:28:01 [13:24] not all people are alike Oct 31 12:28:17 some just want goddam friggin ubuntu on their BBB Oct 31 12:28:21 pronto Oct 31 12:29:11 I'm having a real hard time imagining the hacker who can't download and install software. :) Oct 31 12:29:25 Pronto would also be downloading + install rather than wait for a package from eBay. Oct 31 12:29:26 Anyway, Oct 31 12:29:41 what's the fastest SD read speed one can expect on a BBB? Oct 31 12:29:50 not all people are "hackers" Oct 31 12:29:55 ZiNC: 20MB/s Oct 31 12:30:18 So even UHS that aren't backward compatible should work? Oct 31 12:30:55 yes Oct 31 12:31:00 ZiNC: you should have been at my electronics debugging for softwareengineers talk at elce... it was packed Oct 31 12:31:04 they are backward compatible Oct 31 12:31:15 ZiNC: i would have never thought that so many people would be interested Oct 31 12:31:23 Yeah, not that I'm even sure they exist without non-UHS compatibility. Oct 31 12:31:35 ZiNC: yet, there they are, software people, who barely know how to spell linux who want to do electronics Oct 31 12:31:37 KotH: I think that makes sense. Oct 31 12:31:55 Electronics and software are separate fields. Oct 31 12:31:59 ZiNC: beside: everyone started small Oct 31 12:32:15 ZiNC: i downloaded and installed my first software when i didnt know how to use a computer at all Oct 31 12:32:19 ZiNC: it magically happend Oct 31 12:32:23 ZiNC: and i was happy Oct 31 12:32:33 What age was that? Oct 31 12:32:33 ZiNC: big fat smile on face and dancing in my room Oct 31 12:32:38 19 :) Oct 31 12:32:52 Was your plan to create a satellite control device? Oct 31 12:32:59 Wow. :) Oct 31 12:33:12 no, but i do that these days ;-) Oct 31 12:33:29 I hope you know how to download and install stuff now? :) Oct 31 12:33:53 not really, but i get by with using google and asking av500 :) Oct 31 12:34:07 How much does av500 charge? Oct 31 12:34:14 Hey, you said Google. Oct 31 12:34:24 Something here does not compute. Oct 31 12:35:19 why? Oct 31 12:35:48 A hunch. :) Oct 31 12:36:04 from notre dame? Oct 31 12:36:19 No. From the depths of my brains. Oct 31 12:37:40 so, what hunch? Oct 31 12:37:48 and what does not compute? Oct 31 12:38:00 Ask av500. ;) Oct 31 12:38:45 he is not into psychology, that's my job Oct 31 12:39:17 Oh, that's no psychology. Oct 31 12:39:20 I'm sure he knows. Oct 31 12:39:24 Else, Oct 31 12:39:32 I'd have to charge you for the answer. ;) Oct 31 12:41:07 Which reminds me I should put up an eBay listing... Oct 31 12:41:23 Anyone interested in a 4GB DDR3 1600MHz 11-11-11-28 SODIMM? :) Oct 31 12:48:27 it's all about 1866Mhz CL9 now Oct 31 12:49:42 4GB? such small RAMs still exist? Oct 31 12:50:22 Hey, it was used barely a month, and it can be all yours for only $99! Oct 31 12:50:24 Act now! Oct 31 12:51:21 I am curious if the 1.35V modules I got instead actually work at 1.35V. Oct 31 12:51:42 No software I found can read the RAM voltage, assuming the hardware supports reporting it. Oct 31 12:54:59 use an rpi to bitbang that info Oct 31 12:57:52 By fetching the info thru USB from the laptop's embedded controller? Oct 31 12:58:06 * bradfa buys $20 1 GB micro SD (non HC, non UHS) cards and won't buy anything else now Oct 31 12:58:22 SLC FTW! Oct 31 12:58:28 Nah. Oct 31 12:58:32 TLC FTW. Oct 31 12:58:48 ZiNC, I like their gardening shows the best Oct 31 12:58:51 Preferably without wear leveling. Oct 31 12:58:56 TLC? Oct 31 12:59:05 ZiNC, it's a TV station in .us Oct 31 12:59:17 Apparently Samsung fancy them as well. Oct 31 12:59:27 Which reminds me, Oct 31 12:59:28 Samsung fancies gardening shows? Oct 31 12:59:32 No. Oct 31 12:59:33 TLC. Oct 31 12:59:38 For the 840 EVO and such. Oct 31 12:59:47 what is 840 evo? Oct 31 12:59:54 what kinda wear leveling, if any, happens on the BBB's eMMC? Oct 31 12:59:58 An SSD. Oct 31 13:00:09 ZiNC, wear leveling as specified in eMMC spec, I presume Oct 31 13:00:21 that's what micron data sheet says Oct 31 13:00:28 I always wondered what happens in the embedded flash, and even on USB drives. Oct 31 13:00:28 I read that the TLC from Samsung is almost as good as their MLC Oct 31 13:00:50 therefore the evo is just as viable as the pro Oct 31 13:00:53 for half the price Oct 31 13:00:54 I'm worried about retention. Oct 31 13:00:58 das, that's not hard, MLC sucks balls Oct 31 13:01:03 Not only with TLC. Oct 31 13:01:23 Wait until you get QLC. Oct 31 13:01:42 ZiNC, after QLC is more QLC, though Oct 31 13:01:42 bradfa: bga balls? ;) Oct 31 13:01:54 KotH, yes, but the small ones, chip scale balls Oct 31 13:02:22 So did anyone test real life wear on embedded flashes? Oct 31 13:02:34 lol Oct 31 13:02:44 ZiNC: pointless question is pointless Oct 31 13:02:46 ZiNC, I'm sure manufacturers do Oct 31 13:02:49 ZiNC: and longcat is looooong Oct 31 13:02:56 KotH, why pointless? Oct 31 13:03:08 Manufacturers don't share with me their secrets. Oct 31 13:03:16 MLC will get your 3k erases, SLC 100k, as per most data sheets Oct 31 13:03:24 ZiNC: what is "real life wear"? Oct 31 13:03:27 till SLC goes to smaller process size, then it'll be like 75k erases Oct 31 13:03:29 I have a general idea what that means for SSD. Oct 31 13:03:33 ZiNC: what is the "real" access pattern? Oct 31 13:03:33 But not for simpler things. Oct 31 13:03:43 KotH: Real is not mfg specs. Oct 31 13:04:02 Take a BBB, loop writing to the same sector, and see what happens after a while. Then write over the whole thing and see what happens. Oct 31 13:04:13 ZiNC: so mfg specs are made out of thin air? Oct 31 13:04:23 No. But they're half marketing. Oct 31 13:04:30 ZiNC, eMMC will wear level it, so doing a write life test will be hard unless you udnerstand what the controller is doing internally Oct 31 13:04:31 Or at least, Oct 31 13:04:39 their real life implications are unclear without real life testing. Oct 31 13:05:20 ZiNC: feel free to do that Oct 31 13:05:29 * KotH doesnt really see a point though Oct 31 13:06:13 ZiNC, the controller on MLC managed flash will make orders of magnitude difference in real life write tests compared to the raw nand underneath Oct 31 13:06:49 I assume SSDs use much fancier algorithms than eMMC? Oct 31 13:07:01 And have possible extra processing power and RAM. Oct 31 13:07:04 yes Oct 31 13:07:16 modern samsung ssds have quade core arm processors Oct 31 13:07:25 Would a USB drive be comparable to eMMC, or better, in this regard? Oct 31 13:07:26 ZiNC, well, probably, and about 16x as many flash dies Oct 31 13:07:27 with few gbytes of ram Oct 31 13:07:38 ZiNC, in general USB drives are comparable to cheap SD cards Oct 31 13:07:42 they're shit Oct 31 13:07:44 bradfa: Well, ignoring performance and spare areas. Oct 31 13:07:48 still shit Oct 31 13:07:58 controllers are built to a price, not performance Oct 31 13:08:10 So you'd think UFD, SDs, eMMC are about comparable? Oct 31 13:08:11 * KotH hands bradfa a chocolate cookie Oct 31 13:08:12 more GBs sells more units if priced lower, job done Oct 31 13:08:14 usb sticks get the chips that failed for SSDs Oct 31 13:08:24 sd cards get the leftovers from usb sticks Oct 31 13:08:24 * bradfa nom nom nom Oct 31 13:08:35 av500: i don't think so Oct 31 13:08:44 av500: eMMC is leftovers from SD? :) Oct 31 13:08:46 eMMC target audience is tablets and other > 1M units per year devices, they have decent controllers Oct 31 13:08:51 SD target is being cheap for consumers Oct 31 13:08:57 USB target is being cheap for consumers Oct 31 13:09:00 jacekowski: pls dont question my simplistic world view Oct 31 13:09:06 SSD target is computer "power users" Oct 31 13:09:11 Though I'm sure higher-end devices exist in all catagories. Oct 31 13:09:16 as such, each is priced accordingly and you get what you pay for Oct 31 13:09:30 memory cards are used in dlrs and stuff and have to push 100MB/s in some cases Oct 31 13:09:55 jacekowski, yes, and as such, CF was the choice until recently for high end cameras Oct 31 13:10:00 DLR? Oct 31 13:10:08 DSLR Oct 31 13:10:09 DUPLEX LENSE FEVLXRE Oct 31 13:10:12 Ah. Oct 31 13:10:32 but even compact cameras require more bandwidth now Oct 31 13:10:38 20Mpix pictures are huge Oct 31 13:10:45 jacekowski, you underestimate the amount of SDRAM in modern cameras Oct 31 13:11:05 bradfa: not really Oct 31 13:11:12 bradfa: i have modern DSLR Oct 31 13:11:21 What are the failure modes of such devices? What will one see when cells start failing? CRC warnings? Silent corruption on read/write? Oct 31 13:11:45 bradfa: 256-512 is typical in a DSLR Oct 31 13:11:54 jacekowski, that's a fuckload of ram Oct 31 13:12:09 bear in mind that 20Mpix uncompressed picture is huge Oct 31 13:12:12 ZiNC, writes will succeed, data won't match what you wrote Oct 31 13:12:24 bradfa: Less RAM than an average phone. Oct 31 13:12:31 jacekowski, except in high end slr cameras, uncompressed image data never leaves the sensor chip Oct 31 13:12:32 So silent failures? Oct 31 13:12:44 ZiNC, silent till you want to use the data, yes Oct 31 13:12:46 bradfa: every DSLR that can shoot raw Oct 31 13:12:52 raw isn't sensor image data Oct 31 13:13:01 bradfa: I mean on read. Will it report CRC errors? Oct 31 13:13:04 bradfa: even low end d3100 Oct 31 13:13:12 ZiNC, there's no crc checking on SD Oct 31 13:13:25 of course there is Oct 31 13:13:30 on the underlying nand Oct 31 13:13:31 no? Oct 31 13:13:32 bradfa: raw is is sensor data after compression with losless compression Oct 31 13:13:44 av500, maybe, but you won't see crc errors passed up Oct 31 13:13:46 bradfa: I don't mean SD necessarily. USB drives, etc. Oct 31 13:13:52 That's odd. Oct 31 13:14:09 why? Oct 31 13:14:14 HDDs dont pass CRC data either Oct 31 13:14:20 Because if it's detected, why not pass it on? Oct 31 13:14:24 SD is supposed to look like a hard disk Oct 31 13:14:28 yup Oct 31 13:14:36 CRC is handled at a lower level Oct 31 13:14:37 it has "cylinders" Oct 31 13:14:37 bradfa: but even ignoring that fact, single raw frame on this year dslr is 20-30MB Oct 31 13:14:39 not at OS level Oct 31 13:14:46 jacekowski, ok, so you can buffer 10 to 20 of them Oct 31 13:15:05 ZiNC, if you want to see crc errors, use raw nand or make your own controller Oct 31 13:15:07 I think HDDs do report CRC errors. Oct 31 13:15:12 then, a lot of people shoot raw+jpeg Oct 31 13:15:20 jpeg is small, and horrible Oct 31 13:15:21 ZiNC: nope Oct 31 13:15:26 so you end up having to store 25-35MB Oct 31 13:15:27 agregate yes with smart Oct 31 13:15:36 bradfa: at 20Mpix it's 5MB Oct 31 13:15:48 av500: Not entirely sure, but this comes up: http://support.microsoft.com/kb/817472 Oct 31 13:16:22 bradfa: and bear in mind that ram is shared for everything else that camera does, including storing uncompressed pictures before they get compressed Oct 31 13:16:22 thats CRC on the interface Oct 31 13:16:25 not on the disk Oct 31 13:16:39 What, cables? Oct 31 13:16:41 bit rot is a real thing, you won't see it coming Oct 31 13:16:43 bradfa: D7000, can store 7 raw frames in 256MB Oct 31 13:16:43 yes Oct 31 13:16:55 why would slowing down the interface help with CRC errors on the disk? Oct 31 13:16:56 jacekowski, ok, so buy a UHS card that can actually write fast enough Oct 31 13:16:59 bradfa: which is 1s of shooting Oct 31 13:17:10 jacekowski, ok Oct 31 13:17:11 bradfa: even UHS cards are not fast enough Oct 31 13:17:16 jacekowski, ok Oct 31 13:17:19 we need XHS Oct 31 13:17:24 ZHS! Oct 31 13:17:24 or VHS Oct 31 13:17:28 beta is better Oct 31 13:17:35 you would need card capable of writing 200MB/s+ Oct 31 13:17:35 I have a vague recollection that I didn't get an error reports when I used a Dethstar... Oct 31 13:18:07 that's why high end DSLRs are still using CF which have a lot wider data bus Oct 31 13:18:16 ZiNC: on a HDD, the only error report is "I cannot read this sector" Oct 31 13:18:20 which means the drive is fubar Oct 31 13:18:26 copy all remaining data and bin it Oct 31 13:18:37 av500, or replace the servo motors Oct 31 13:18:42 everything else happens below the OS level Oct 31 13:18:53 bradfa: fill er up and change er oil? Oct 31 13:19:03 could be the distributer' or could be coil? Oct 31 13:19:12 av500, yes, check the wires too Oct 31 13:19:19 damn wires! Oct 31 13:19:20 my pump timing belt has snapped recently Oct 31 13:19:23 we need wireless engines! Oct 31 13:19:30 wireless is always better Oct 31 13:19:37 I used to have strange reading errors on some computer. Happened rarely, on data files, I don't think I ever saw OS problems. Oct 31 13:19:41 jacekowski: perfect timing :) Oct 31 13:19:57 ZiNC, turn hard disk over and shake, that helps the proper bits get aligned Oct 31 13:20:04 I managed to find bit patterns that caused it. I assumed it's the controller. Oct 31 13:20:24 Eventually the problem disappeared. I don't know, maybe after replacing a PSU. Oct 31 13:20:37 But for a while I disabled DMA. It worked without errors with PIO. Oct 31 13:20:49 dma is always the root cause Oct 31 13:21:07 But anyway, it was silent. No errors reported by the OS. Oct 31 13:21:28 yes, interface errors did happen Oct 31 13:21:34 like using 40pin cables for udma Oct 31 13:21:42 DMA on x86 is a mess anyways Oct 31 13:21:48 was Oct 31 13:21:48 scsi all the things! Oct 31 13:21:53 x86 is gone, remeber Oct 31 13:21:57 +m Oct 31 13:21:59 because you can never do proper DMA on x86/x64 Oct 31 13:22:04 it will always go through cpu Oct 31 13:22:16 because cpu always snoops all dma transfers to keep cache coherent Oct 31 13:22:17 yeah, that slows my PC down a lot Oct 31 13:22:25 and the nsa chips Oct 31 13:22:30 same thing Oct 31 13:22:33 :) Oct 31 13:22:46 see, cache and NSA even have one letter in common Oct 31 13:22:49 coincidence? Oct 31 13:22:52 I doubt it Oct 31 13:22:56 The NSA chips include RF connectivity, yes? Oct 31 13:22:59 with so many letters Oct 31 13:23:06 how do blind people use SLR cameras? Oct 31 13:23:13 apparently new intel i7 chips have 3g modem inside Oct 31 13:23:23 bradfa: with the lens cap on Oct 31 13:23:31 +1 Oct 31 13:23:44 With their hands? Oct 31 13:24:38 ZiNC, how do blind people with no hands use SLR cameras? Oct 31 13:24:49 Legs? Oct 31 13:24:54 iOS app Oct 31 13:25:14 There's this swimmer, I think pro, with no hands. Oct 31 13:25:20 Surely operating a camera is easier. Oct 31 13:25:28 xfburn won't let me blank a dvd-rw because it's already blank but won't let me write to the disk until I blank it... Oct 31 13:25:40 -rw? Oct 31 13:25:45 that still exists? Oct 31 13:25:50 Why not? Oct 31 13:26:01 av500, it's an old disk Oct 31 13:26:01 reminds me of the single VHS tape I had Oct 31 13:26:05 i've not used optical media for at least 5 years Oct 31 13:26:08 boy, that watched a lot of TV for me Oct 31 13:26:16 it's faster to download something from the interwebs Oct 31 13:26:26 bradfa: why it is not in a bin? Oct 31 13:26:31 I had to throw out a cd-rw from 2005, it was having silent bit errors Oct 31 13:26:37 Sadly optical is still the most practical archival medium. Oct 31 13:26:37 av500, I'm cheap Oct 31 13:26:43 silence of the bits Oct 31 13:26:56 ZiNC: magnetic tapes Oct 31 13:27:01 I'm considering installing debian Oct 31 13:27:02 Not for me. Oct 31 13:27:02 bradfa: cheap is fine, but you are reckless Oct 31 13:27:19 now, that is cheap Oct 31 13:27:25 I hear it's free Oct 31 13:27:28 I'm still waiting for BDXL to add single layer to the standard... Oct 31 13:27:48 ZiNC, cut the disk in half Oct 31 13:27:56 I want 32GB. Oct 31 13:28:12 ZiNC, I have a usb memory stick with 32 gb, want that? Oct 31 13:28:15 or add that hole and use the back side too Oct 31 13:28:19 it will corrupt on you Oct 31 13:28:45 bradfa: I trust optical discs more for long term storage. Oct 31 13:29:00 ZiNC, flash is about the same Oct 31 13:29:05 But re that USB, it sounds like a good one to test wear leveling behavior on. Oct 31 13:29:06 10 years is pushing both Oct 31 13:29:28 Flash is electronics. It can catastrophically fail. Oct 31 13:29:30 clay tablets are just fine Oct 31 13:29:40 Good discs, in my experience, degrade gradually. Oct 31 13:29:44 av500, they get misinterpreted though Oct 31 13:29:53 anything does Oct 31 13:30:00 ZiNC, if one bit flips in a forest and no one hears it, did it flip? Oct 31 13:30:06 Yes. Oct 31 13:30:18 Objective is objective. Oct 31 13:30:30 And you can add PAR2. Oct 31 13:30:35 bradfa: pine or oak forest? Oct 31 13:30:38 I mostly get bogies Oct 31 13:30:42 oak Oct 31 13:30:53 A-OK Oct 31 13:31:00 a team? Oct 31 13:31:11 Anyway, I'm happy so far with the performance of optical discs. I don't think I've ever had one fail (after it was deemed a successful write). Oct 31 13:31:20 ZiNC, buy the gold ones Oct 31 13:31:28 I have various. Oct 31 13:31:35 24k or 14k gold? Oct 31 13:31:41 Never checked. Oct 31 13:31:52 bradfa: ethically mined? Oct 31 13:31:57 * bradfa takes golden cd-r to pawn shop Oct 31 13:32:05 av500, of course! Oct 31 13:32:44 * bradfa goes to play fedex soccer (foooootball) with arriving packages Oct 31 15:19:55 hi, can someone please tell me which defconfig is used for building the beaglebone black images in angstrom? Oct 31 15:21:24 there are many defconfigs in the setup-scripts directories and many subdirs say "beaglebone" Oct 31 15:57:47 After much hassle, I got the FTDI drivers installed although Win8 is reporting that they are unsigned and changed cables. I am still unable to establish a serial console to the BBB. Any suggestions would be helpful. Oct 31 15:57:58 my next step will be to flash it again. Oct 31 16:02:46 make a loopback Oct 31 16:02:55 then you should see what you type in your terminal app Oct 31 16:03:00 test this forst Oct 31 16:03:01 first Oct 31 16:03:44 Does anyone know the beagle board black has passed the EMC measurements? Oct 31 16:04:03 hi is anyone here? Oct 31 16:04:06 it has FCC and CE Oct 31 16:04:09 ricouzuki: no Oct 31 16:04:26 how can i find the reports? Oct 31 16:04:37 no idea Oct 31 16:04:43 ask gerald on the ML Oct 31 16:04:45 quick question: Does beaglebone black have its ethernet adapter connected directly to the cpu or is it over usb? Oct 31 16:04:46 what for? Oct 31 16:04:52 ricouzuki: direct Oct 31 16:04:59 the schematic tells you that, btw Oct 31 16:05:01 thank you Oct 31 16:12:25 av500: I'll try that later. Oct 31 16:13:07 do or do not, there is no try Oct 31 16:43:11 nom nom nom Oct 31 16:52:38 Hi, I'm trying to use a beagle bone black and can't understand why b.pinMode('P8_3', b.INPUT); b.digitalRead('P8_3', printStatus); would not work where the same with P8_19 will (I'm trying to play around with the demo) Oct 31 16:53:11 Is there some kind of call to switch to "65 I/O mode" ? Oct 31 18:04:02 JohnH: maybe that pin is already in use? Oct 31 18:09:23 Hey all, I just got a beaglebone black, and I'm having some trouble getting it to do anything. I'm probably doing something really obvious wrong, but I'd appreciate some help Oct 31 18:10:20 I'm going through the tutorial at http://beagleboard.org/Getting%20Started, and have gotten as far as installing the drivers (I'm on a 64 bit Windows 7 machine) Oct 31 18:10:41 So, I installed the windows 64 bit drivers and restarted, but can't seem to connect to the board Oct 31 18:11:30 I'm using a blank microsd card, because the board didn't seem to come with one, so that may be the problem Oct 31 18:11:43 yes, remove the microsd card Oct 31 18:13:23 Well geeze, now I feel like an idiot :P Oct 31 18:13:32 Thanks for your help! Oct 31 18:13:35 did it work? Oct 31 18:14:02 I took out the card, unplugged it, and plugged it back in, and now my computer is recognizing a new device Oct 31 18:14:06 which it wasn't doing before Oct 31 18:14:13 so it definitely helped Oct 31 18:21:04 hello fellow beaglers Oct 31 18:23:33 excuse me anybody know why opkg update fails to wget anything? Oct 31 18:24:13 do you have internet connection and is your /etc/resolv.conf set correctly? Oct 31 18:32:28 @biodragon it's working now! Oct 31 18:34:01 yay! :) Oct 31 18:54:50 hi Oct 31 18:55:23 which version of ubuntu I can mount on the card? Oct 31 18:55:40 i need only linux withouth graphics Oct 31 18:56:20 how to customize kernel? there is a LTIB here? Oct 31 18:56:26 i must buy this board Oct 31 18:56:33 but i want some information Oct 31 18:57:15 hi Oct 31 18:57:24 there is someone here? Oct 31 18:57:49 No. Oct 31 18:57:58 We all died at breakaway station. Oct 31 19:01:59 :) Oct 31 19:02:07 you can answer me plz Oct 31 19:05:55 what's ltib? Oct 31 19:07:50 for to customize kernel Oct 31 19:08:06 i dont want ubuntu image with all graphiics file Oct 31 19:08:41 i need a simple linux with an uboot a minimal kernel that i customize (serial, ethernet, gpio) and a little rootfs Oct 31 19:26:00 Was wondering if anyone got the hwrng working under linux (ubuntu or debian)? Oct 31 19:27:11 I see it in the kernel, but see no /dev/hwrng in /dev, no way to install module. Oct 31 19:29:34 ok Oct 31 19:30:24 To turn the ARM chip off in the BBB using the PRUs, I have to interface it with the cortex m3 right{ Oct 31 19:33:05 Eigen, that's a really generic question, but yes, if you want to do PM things, use the M3 Oct 31 19:33:17 ok Oct 31 19:33:24 I'll be more specific Oct 31 19:33:36 I want to fire an interrupt in my pru Oct 31 19:33:49 to wake the arm chip Oct 31 19:33:58 from standby mode Oct 31 19:34:00 *the Oct 31 19:34:27 I was reading through the 335x reference manual on it Oct 31 19:35:38 But then what is the use of the PMIC then Oct 31 19:36:08 do i use that instead? Oct 31 19:36:38 it doesn't look like the m3 has a dedicated pru wakeup Oct 31 19:36:53 so you'd have to keep the intc on and use the mpu wake source Oct 31 19:37:25 why does the mpu need to be in standby? Oct 31 19:38:06 any code for getting the Random Number Generator working through a module? Oct 31 19:38:30 Russ: it wasn't my idea Oct 31 19:38:32 #nick symgryph Oct 31 19:38:40 nick symgryph Oct 31 19:38:44 my team leader thinks we should do it to save power Oct 31 19:39:01 Eigen, prus are in the per power domain to begin with Oct 31 19:40:03 cpuidle support isn't integrated yet, but that's probably what you'd want Oct 31 19:42:08 yes Oct 31 19:42:27 are there no examples Oct 31 19:43:17 what is the poweron time from standby and the deepsleep 0 and deepsleep1 modes? Oct 31 19:43:35 Or is that something that I have to test Oct 31 19:43:41 are you aware what the different modes turn off? Oct 31 19:43:49 yes Oct 31 19:43:51 that the prus are in the per domain/ Oct 31 19:44:37 Eigen, google for spruh73c.pdf, I think it might help you Oct 31 19:44:48 I don't think the kernel support is ready for sleep/wake Oct 31 19:45:03 Hell Oct 31 19:45:07 Hello*** Oct 31 19:45:26 does anyone know what acesories Oct 31 19:45:37 I will require with the beagle bone black Oct 31 19:45:38 e.g Oct 31 19:45:45 what type of sd card? Oct 31 19:46:38 Vaizki: What is the diff between spruh73i and f and c Oct 31 19:46:51 ok] Oct 31 19:47:05 so if I'm in standby then the per domain is on Oct 31 19:56:06 Eigen, version number Oct 31 19:56:13 yes Oct 31 19:56:16 Eigen, in later versions, they removed the pru documentation Oct 31 19:56:19 oh Oct 31 19:56:21 omg Oct 31 19:57:04 oh right. I read somewhere that the prus are not official supported by ti anymore Oct 31 19:57:58 Anyone got Hardware RNG to work on BBB? Oct 31 20:01:14 RNG, BBB? (Rhyming) linux module? Oct 31 20:02:03 Symgryph, its supported in kernel Oct 31 20:02:09 there is a dt entry for it Oct 31 20:02:36 I did see the option, but saw no device node. Oct 31 20:02:53 Not listed in dmesg output either. Oct 31 20:02:55 kk thx Russ Oct 31 20:02:58 cya Oct 31 20:03:11 Thanks russ, for the answer. Oct 31 20:03:39 I was using the included ubuntu distro (not angstrom). That might be the problem. Oct 31 20:04:04 The link that is.... for ubuntu. Oct 31 20:05:49 http://elinux.org/BeagleBoardDebian#Debian_7_.28wheezy.29 Oct 31 20:10:28 which version of ubuntu I can mount on the card? Oct 31 20:10:30 i need a simple linux with an uboot a minimal kernel that i customize (serial, ethernet, gpio) and a little rootfs Oct 31 20:10:33 i dont want ubuntu image with all graphiics file Oct 31 20:10:36 i need a simple linux with an uboot a minimal kernel that i customize (serial, ethernet, gpio) and a little rootfs Oct 31 20:10:42 i dont want ubuntu image with all graphiics file Oct 31 20:13:59 I used 12.04 elinux 13.10 also works, VERY minimal no graphical stuff Oct 31 20:28:13 Symgryph: but i can to customize kernel? Oct 31 20:35:08 How to customize kernl on Beagle black? Oct 31 20:41:24 /msg NickServ HELP Oct 31 20:48:19 Hi everybody ! Oct 31 20:48:21 I have got a beaglebone black and I would like build angstrom distrib for my board. Oct 31 20:48:23 I need more information about the build workflow, specialy about Open Embedded. Someone can help me ? Thx Oct 31 20:51:12 Helloooo Oct 31 20:51:15 Anyone here??? Oct 31 20:52:13 sure, just ask question Oct 31 20:52:21 well my forth compiler for arm just compiled its first definiton yay Oct 31 20:53:03 seems i had quite a few bugs in my arm assembler code... and ive only debugged a small part of the compiler so i think it will be a while before its fully working :) Oct 31 20:58:21 Hi Oct 31 20:58:32 i was planning of buying a Beagleboard - Black. Oct 31 20:58:45 I know it requires a number of accessories E.g power cable. Oct 31 20:58:53 what exactly will i need? Oct 31 20:59:59 You need an usb cable Oct 31 21:00:20 an FTDI cable Oct 31 21:00:37 I bought this one Adafruit 4 Pin Cable (PL2303) Oct 31 21:01:11 an HDMI <-> microHDMI cable Oct 31 21:01:15 the adafruit one is good but if you live near a frys electronics they will probably have one in stock Oct 31 21:02:25 There are some example of accessories on this page : http://circuitco.com/support/index.php?title=BeagleBone_Black_Accessories Oct 31 21:05:07 And an USB Hub Oct 31 21:06:43 and don't forget... some patience. heh Oct 31 21:10:02 anyway to get ubuntu to fully shutdown on the BBB? Oct 31 21:11:18 poweroff and pull the power Oct 31 21:13:47 On this page http://circuitco.com/support/index.php?title=BeagleBoneBlack#Angstrom Oct 31 21:13:49 They recommend to build angstrom from this sources : Oct 31 21:13:51 Bootloader: http://www.denx.de/wiki/U-Boot/SourceCode (git://git.denx.de/u-boot.git) Oct 31 21:13:53 Kernel: http://github.com/beagleboard/kernel/tree/3.8 Oct 31 21:13:55 Root file system: http://github.com/beagleboard/meta-beagleboard Oct 31 21:13:57 And on the angstrom page, they build from git clone git://github.com/Angstrom-distribution/setup-scripts.git Oct 31 21:13:59 Which of this two solution is the best/right ? Oct 31 21:14:25 haha... jee thanks thurgood! but that's impractical. ;) Oct 31 21:22:46 Has anybody had luck with I2C in debian on the BBB? I have a device connected on pins P9_19 (SCL) P9_20 (SDA), 3.3V power and GND and it is not showing up with i2cdetect Oct 31 21:23:37 On an Arduino (the device works with 3.3 and 5 volts), it works, so I believe that I've soldered the connections correctly and have the basic wiring correct Oct 31 21:39:20 jbdatko: well if you know where it is then just try to use it and not i2cdetect? Oct 31 21:39:36 also if you have a scope / la, hook it up and see Oct 31 21:40:32 Vaizki: unfortunately, no la. But yes, I do know the address. Do I have to add it /sys/bus/i2c/devices/i2c-1 ? Oct 31 21:43:32 jbdatko, well I would say that you just use /dev/i2c-1 and iotctl(fd, I2C_SLAVE, addr) to select it.. then read() / write() Oct 31 21:44:15 Vaizki: ah, ok. I'll give that a shot, thanks Oct 31 21:44:25 detecting i2c devices via "probing" should be avoided unless absolutely necessary Oct 31 21:44:45 B/c it disrupts the rest of the devices on the bus? Oct 31 21:45:01 such is life in the embedded bus world, very rarely you get reliable enumeration Oct 31 21:45:22 well not only disrupts but probing some devices can wipe them etc Oct 31 21:45:37 there is no real "probe" command in i2c, which is a damn shame but that's how it is Oct 31 21:45:54 https://www.kernel.org/doc/Documentation/i2c/instantiating-devices Oct 31 21:46:04 there is some docs on the /sys interface to i2c Oct 31 21:46:10 http://elinux.org/Interfacing_with_I2C_Devices Oct 31 21:46:29 and that looks like a pretty short overview of the open() ioct() read() write() to talk to it Oct 31 21:47:05 great! thanks Oct 31 21:47:16 what language are you using? Oct 31 21:48:06 those same ioctl:s etc are available for example in Python which I use to quickly prototype stuff Oct 31 21:48:07 C or python. But I was getting hung up on it not showing up in i2cdetect. Oct 31 21:48:46 I saw the Adafruit i2c lib: https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/blob/master/Adafruit_I2C/Adafruit_I2C.py Oct 31 21:51:19 jbdatko: won't hurt to make it from scratch and learn what you're doing :) Oct 31 21:51:59 true :) thanks for the pointers Oct 31 21:56:04 because really it's much more simple than it looks from those layered python libs/packages Oct 31 21:57:30 Ok, I'll read those docs and give it a shot in c. Oct 31 22:05:05 i noticed that beagle made a good showing at last years Embedded Linux Conference. I'd love to get some of that kind of interaction, but the next ELC isn't until late spring next year. Are there any other conferences that beagle gets talked about a bunch (tutorials and the like)? Oct 31 23:06:31 can i ask a question> Oct 31 23:07:13 it is on bbb ddr3 circuit. i do not see terminator resistors on schemtic Oct 31 23:12:40 the board works - so probably they are not needed Oct 31 23:12:56 travisgriggs : you just missed ELC-Europe Oct 31 23:18:30 bummer :( Oct 31 23:27:35 travisgriggs: if you're looking to learn, you should check out the training material at Free Electrons Oct 31 23:28:08 http://free-electrons.com/doc/training/embedded-linux/ Oct 31 23:56:20 Hey all. I heard a rumor that the beagle board folks will print custom beagle bones. Any truth behind that? Oct 31 23:56:46 Hey Guys :) Can anyone help me with a systemd issue on BBB? Oct 31 23:59:02 brm2, what's the issue? Nov 01 00:01:29 Hey Guys :) Can anyone help me with a systemd issue on BBB? Nov 01 00:02:34 ^^^^^ Nov 01 01:15:23 anyone with angstrom on the bbb feel like doing me a favor? Nov 01 01:18:42 nm Nov 01 01:21:57 depends Nov 01 01:22:03 currently upgrading angstrom on it Nov 01 01:36:36 what's going on sheldonw Nov 01 01:37:21 was trying to get a properly patched dtc for ubuntu, but I found the right resource that robert nelson posted on getting a patched copy. thanks anyways. Nov 01 01:37:44 lol ok Nov 01 01:54:40 is there a different channel for development? Nov 01 01:59:01 PDilyard: we only support those that are developmentally challenged.... Nov 01 02:32:07 I am going to love this board, aren't I? Nov 01 02:47:37 hmm 363 bogomips on bbb :/ **** ENDING LOGGING AT Fri Nov 01 02:59:58 2013
