Son, I'm Disappoint Sep 02 08:36:55 well, sprüngli is good for cakes Sep 02 08:37:19 but you have to go to the shop to order them, which is probably impossible for Adil Sep 02 08:37:53 yes you know that.kindly suggest the easiest way for me Sep 02 08:38:21 Adil: i'll give you the exact steps: Sep 02 08:38:25 Adil: 1) ask your question Sep 02 08:38:34 moaning Sep 02 08:38:42 Adil: 2) describe what you want to do, what you have done and why it failed Sep 02 08:38:47 Adil: 3) wait for the answer Sep 02 08:38:55 mru, moaning Sep 02 08:39:00 Adil: 4) buy lots of good swiss chocolate Sep 02 08:39:12 Adil: come to edinburgh to elce and distribute it among the #beagle trolls Sep 02 08:39:50 mru: howdy! Sep 02 08:40:31 hey mru Sep 02 08:40:37 * LetoThe2nd is just trying to decide "join troll master meeting a.k.a. yocto project developer day europe or not" Sep 02 08:40:44 mru: how was your weekend not-in-paris? ;) Sep 02 08:40:52 not in paris Sep 02 08:41:32 paris is overrated anyway Sep 02 08:41:47 there are good looking girls overthere Sep 02 08:42:00 though they speak french :-/ Sep 02 08:42:14 there are french girls everywhere Sep 02 08:42:42 nope, not in zürich Sep 02 08:42:51 they rather stay in the western part of switzerland Sep 02 08:43:01 but I'm not in zürich either Sep 02 08:43:08 good thing Sep 02 08:43:18 very few good looking girls overhere Sep 02 08:43:25 so why are you there?

Sep 02 08:48:37 LetoThe2nd: ok, then i'll blame you for any misfortune that happens to me Sep 02 08:49:43 p About at least half of mankind does so, hence i can take that. Sep 02 08:50:07 * _troll_ eats KotH Sep 02 08:50:36 _troll_: did he taste like chocolate? Sep 02 08:51:09 * KotH is like a stone in _troll_'s stomach Sep 02 09:01:00 i've been fighting stupid kernel parameters all day Sep 02 09:01:09 intel motherboard Sep 02 09:01:10 at least you didn't say kernal Sep 02 09:01:12 that's a start Sep 02 09:01:22 mru: kennel. Sep 02 09:01:24 debian build. Sep 02 09:01:35 not on bbb Sep 02 09:01:49 mrpackethead: build your kenal yourself Sep 02 09:02:02 kept turning off the hdmi just after grub Sep 02 09:02:19 foruantly i founda very obscure note on somebodys web pages Sep 02 09:02:28 theres a minor bug Sep 02 09:02:33 but a work around Sep 02 09:02:44 good old vga text console or newfangled fbcon? Sep 02 09:02:57 KotH: build a kernel. Blah.. thats too hard. Sep 02 09:03:01 plenty of kernel trolls to do that Sep 02 09:03:18 mrpackethead: remove the "quiet" entry in the grub config at bootup Sep 02 09:03:29 mru: if it's a standard debian install: newfangled fbdev Sep 02 09:03:54 whose moronic idea was it to have even the option of silent boot? Sep 02 09:04:09 Gates Sep 02 09:04:15 Doors Sep 02 09:04:33 from the sirius cybernetics corporation? Sep 02 09:04:34 "silent boot" it could be an album name Sep 02 09:04:48 mru, you mean the first idiots up a well when the revolution comes? Sep 02 09:04:50 or a bnad name Sep 02 09:04:54 *up against a wall Sep 02 09:04:57 nah. best album title ever: "smell the glove" Sep 02 09:05:30 I'm building a button station Sep 02 09:05:32 with a bbb Sep 02 09:05:42 wtf is that? Sep 02 09:05:51 i wished my pcb mill was here working Sep 02 09:05:53 :-( Sep 02 09:05:55 sigh. Sep 02 09:06:18 mru: ubanto Sep 02 09:06:34 mru: you knwo, lots of text during boot up scares people Sep 02 09:09:20 Hello, just wondering how many pins on the Black I could open at the same time Sep 02 09:09:24 mru: and scared people are bad for business if you want to sell them cloude appliances Sep 02 09:09:35 I thought fear sells Sep 02 09:09:38 fear and sex Sep 02 09:09:42 Splat: using a skalpel, i'd say 10 Sep 02 09:09:55 mru: only fear of other things Sep 02 09:10:06 mru: like terrorists, or black chocolate being thrown at you Sep 02 09:12:40 Thanks KotH Sep 02 09:13:43 Splat: other than that, the question does not make sense Sep 02 09:15:06 brb Sep 02 09:49:06 can you have a dhcp address and a secondary static address on an interface Sep 02 09:49:10 i would have thoght so Sep 02 09:49:14 but i'm not entirely sure. Sep 02 09:49:24 sure Sep 02 09:50:13 but i dont know how the usual suspects of dhcp clients behave when you configure a static address on an interface and then use dhcp on it Sep 02 09:50:25 the "old" :1 sub-nic should work though Sep 02 09:50:36 dunno about the ipaddr way Sep 02 09:51:54 headless installation Sep 02 09:52:02 its always a bit tricky Sep 02 09:52:23 please stop that stupid m$ speak of headless computers Sep 02 09:52:38 computers dont have heads, and even if they would, behading them would be cruel Sep 02 09:53:57 just say whether you have no gui, no vga/dvi/hdmi console or no local console (ie not even serial) at all Sep 02 09:58:22 you can always add more addresses after dhcp has done its thing Sep 02 09:59:46 mru: most dhcp clients redo the whole process when the lease expires Sep 02 09:59:57 mru: some even clearing the other configured ip addresses Sep 02 10:01:23 removing addresses when renewing a lease would be evil Sep 02 10:01:46 there'd be a moment when the interface had no address if you did that Sep 02 10:01:46 * m_billybob nods Sep 02 10:01:51 morning Sep 02 10:02:19 mru: user space programs are evil Sep 02 10:02:26 moin m_billybob $ Sep 02 10:02:27 you could always use a hook script to reapply any extras Sep 02 10:02:32 juup Sep 02 10:02:44 KotH, someone step on your tail this morning ? Sep 02 10:03:11 hmm? why? Sep 02 10:03:57 must be me, Sep 02 10:04:06 could be that i'm little grumpy Sep 02 10:04:06 i just woke up Sep 02 10:04:09 dont know Sep 02 10:04:19 _could_ be? Sep 02 10:04:21 didnt sleep much the last couple of days Sep 02 10:04:34 ok, i am grumpy, your point being? ;) Sep 02 10:04:57 * KotH walks off into a corner and eats some chocolate Sep 02 10:05:14 heh dont do that Sep 02 10:05:27 well surechocolate . . .always Sep 02 10:08:11 meh! do people even think before they start doing schematics Sep 02 10:08:19 no Sep 02 10:08:23 looks like Sep 02 10:08:33 whats this thinking ? Sep 02 10:09:29 * m_billybob doesnt do many schematics though Sep 02 10:09:41 i'm sitting here infront an analog differential to single ended converter that has some measures to "reduce" noise, that make CMRR and PSRR so bad, that the following 12bit ADC will get signal error in the range of 100-500LSB Sep 02 10:10:19 woosh ! Sep 02 10:13:38 ah ! groups -> microsoft keyboard not recognized ! *delete. Sep 02 10:28:19 the eth0:1 trick works Sep 02 10:28:25 ha'dnt tryed the obvious Sep 02 10:28:26 :) Sep 02 10:28:30 eeew Sep 02 12:11:19 Hi! I have a 4DCAPE-43T display with resisitve touch connected to my BBB. I have calibrated the sceen, now it seems that i have to press harder on the touchscreen to make accurate inputs, otherwise there is some jitter, i.e. cursor jumps to the side, up or down. Is this normal for all resistive touch screens? Sep 02 12:11:39 yes Sep 02 12:11:54 apply some filtering Sep 02 12:12:13 there is a huga variation in resistive TS quality Sep 02 12:12:16 huge Sep 02 12:12:39 av500: thanks, I am using tslib, do I have to edit the ts.conf? Sep 02 12:12:57 no idea Sep 02 12:13:01 what is it? Sep 02 12:13:49 still using tslib? Sep 02 12:13:53 it's not 2003 anymore Sep 02 12:13:55 use evdev Sep 02 12:15:02 sorry, I saw it in derek molloys video thought it would be the best for use with Qt Sep 02 12:16:37 I will have a look at evdev to see what it does Sep 02 12:17:23 av500: in ts.conf you can set some params for dejitter etc for tslib Sep 02 12:17:34 well, try and find out Sep 02 12:18:06 now I will follow koen's advice to see what evdev is Sep 02 12:24:50 Anguel: stop using youtube! Sep 02 12:24:55 Anguel: real knowledge comes from irc! Sep 02 12:25:40 KotH: yesterday I tried asking you something and you sent me to buy a linux book :( Sep 02 12:26:40 Anguel: of course Sep 02 12:26:49 Anguel: knowing the system you are using is essential Sep 02 12:27:05 Anguel: but really, do not rely on youtube videos for knowledge Sep 02 12:27:14 KotH: sorry but i have to start somewhere, knowing Linux does not mean I know how touchscreens are interfaced Sep 02 12:27:23 Anguel: they are usable as intros to a completely new field, but do not trust anything you see there Sep 02 12:27:59 Anguel: nothing against starting somewhere :) Sep 02 12:28:16 Anguel: and knowing linux will help you knowing about touch screens ;) Sep 02 12:28:37 KotH: you are probably right, but derek molloy has put a lot of effort there and his demos work, maybe there are some better ways but as I said, you don't get much information from other places Sep 02 12:29:08 feel free to follow whaterver tutorials Sep 02 12:29:15 Anguel: the problem is that embedded linux is such a wide field, nobody can hope to write a good introduction Sep 02 12:29:32 its just that we dont even know who derek molloy is Sep 02 12:29:43 so its hard with follow up questions Sep 02 12:29:46 Anguel: i usually end up reading a dozen tutorials, then go into the documentation of the tools used and see wether there is a better way Sep 02 12:29:50 otherwise, whatever works for you is OK Sep 02 12:30:15 KotH: you are right, and even the big experts don't know if they have not worked with a specific part Sep 02 12:30:40 exactly Sep 02 12:30:47 derrek malloy does fairly decent video tutorials for electronics, and embedded systems - afterall he is a professor at dublin uni Sep 02 12:30:51 though, you can get pointer to nearly everything in this channel Sep 02 12:31:17 ( i think its dublin uni anyhow ) Sep 02 12:31:27 m_billybob: having been at universities, i can tell you that being a professor doesnt mean you know what you are talking about :) Sep 02 12:31:35 av500: Dr. Derek Molloy is a Senior Lecturer in the School of Electronic Engineering, Faculty of Engineering & Computing at Dublin City University. He lectures in Object-oriented Programming, 3D Computer Graphics and Digital Electronics at postgraduate and undergraduate levels. His research interests are in the fields of Computer & Machine Vision, 3D Graphics & Visualisation and e-Learning. He is a key academic member of the Centre f Sep 02 12:32:12 he does but like you said KotH, embedded system and electronics is a rather wide field Sep 02 12:32:24 no one can hope to cover it all Sep 02 12:32:45 m_billybob: dmolloys videos are nice, but far from perfect. they're more like: "hey see, i tinkered this thing into place and let you watch." Sep 02 12:32:59 yeah his videos are rather limited Sep 02 12:32:59 maybe we should start to write a beagle-book, that contains everything about exact steps and opencv Sep 02 12:33:07 oh.. and the codes! Sep 02 12:33:32 KotH: can you giv me ur mail plz so u can send me teh codez plz? Sep 02 12:33:39 ah no, the other way round.... Sep 02 12:33:54 LetoThe2nd: 0000 Sep 02 12:33:54 KotH: can i giv u my mail so i can send u teh codez plz... Sep 02 12:34:02 LetoThe2nd: that's the code Sep 02 12:34:06 LetoThe2nd: if that doesnt work, try 1234 Sep 02 12:34:10 still wrong. damn. i wonder why that never works. Sep 02 12:34:54 LetoThe2nd: ...zlp zedoc het u dnes nac i os liam ym u vig i nac :HtoK Sep 02 12:34:59 * KotH wonders why IC manufacturers give you detailed spice models of their devices, but no circuit diagram anymore Sep 02 12:35:10 * KotH hates reverse engineering circuits from spice netlists Sep 02 12:35:28 das: you have it all backwards! Sep 02 12:37:01 hungarian notation ;) Sep 02 12:38:02 notated hungarians? Sep 02 12:38:05 someone got familiar with trolling techniques pretty quickly Sep 02 12:38:33 das: either he is a quick learner or has been trolled before Sep 02 12:40:18 KotH: not in here obv Sep 02 12:46:53 koen: Do you know if evdev works with Qt embedded's QWS, i.e. without X11? Sep 02 12:50:05 my guess would be no Sep 02 12:50:10 In computing, evdev (for event device) is a component of the Linux kernel for handling input (from keyboards, mice, joysticks, etc.) and a closely related input driver for the X.Org Server. The kernel component is glue code which translates input events from peripheral-specific drivers into a generic structure which the input driver can easily translate into X11 events. Thus every input device with a Linux driver is compatible with the X.Org input driver, Sep 02 12:50:32 wikipedia ( take with a grain of salt ) Sep 02 12:51:57 evdev does in no way require X Sep 02 12:53:25 more like X requires evdev to avoid supporting everything itself Sep 02 12:54:10 many thanks, somehow I misinterpreted the "closely related" Sep 02 12:54:15 so in other words, wikipedia shows its worth once again Sep 02 12:54:22 but is it network transparent? Sep 02 12:54:28 ( not very useful ) ^^ Sep 02 12:54:48 mru: funny, I see a "troll" user now in my local dc++ Sep 02 12:54:51 is that you? Sep 02 12:55:02 dc++? Sep 02 12:55:05 that still exists? Sep 02 12:55:31 yes Sep 02 12:56:23 o_0 Sep 02 12:56:35 av500: i knew you were old, but that old? Sep 02 13:00:36 haha my old boss in his new company: "Here they studied every good solution and decided to use none of them" Sep 02 13:01:26 KotH: I use whatever Hollywood forces people into using Sep 02 13:09:00 Anguel: yes, qt-e works with evdev, the qt docs would have told you that Sep 02 13:13:11 koen: thanks, I will look into this. had googled it and somehow got only answers that people could not get it to work with QWS and had to go back to tslib Sep 02 13:15:19 I bet those are the same people who claim to need a python library to echo a single value to sysfs Sep 02 13:16:23 only node.js can do that Sep 02 14:09:45 av500, i thought that was shell script only Sep 02 14:38:24 Dear Sir, I am using beagle board black, I flashed custom image into micro SD card, it booted from SD card but after that other than power LED nothing is glowing. Sep 02 14:39:04 The beagle board is not detecing connected to PC Sep 02 14:39:19 I am expecting internal flash image corrupeted Sep 02 14:39:50 Now i am not able use board, Could you share your thoughts Sep 02 14:42:01 * KotH shares "i need to get milk" Sep 02 14:42:34 Rama: connect a serial cable and see what the bbb is doing Sep 02 14:57:23 the bbb could just need to be reset again. this happens from time to time Sep 02 14:57:41 e.g. unplug, then replug the power source. Sep 02 17:24:38 anyone have made a beaglebone clone with 2ethernet ? Sep 02 17:32:05 acidfoo: the second mac is not accessable on the black, so you would need to add the second nice via the GPMC interface or using one of the SPI to ethernet chipsets Sep 02 17:39:28 prpplague, yes, looking for a clone that added another one Sep 02 17:39:57 acidfoo: no need for a clone, just create a cape with one on it Sep 02 17:40:08 acidfoo: what are you trying to accomplish? Sep 02 17:40:21 acidfoo: you can also simply use a usb ethernet dongle Sep 02 17:40:25 I want to build a network device, and I really need 2 ehternets port Sep 02 17:40:39 does using the usb is reliable ? Sep 02 17:41:00 and usb dongle are not that cheap I think Sep 02 17:41:06 as reliable as any other pc running linux with a usb dongle Sep 02 17:41:06 Any of you have both a bbb and a cubieboard2 by chance? Sep 02 17:41:32 All of my boxes except my laptop run usb wireless Sep 02 17:41:46 to answer someone's question about usb network cards Sep 02 17:41:58 I dont know why I'm trying to avoid a usb dongle, I'll give a shot Sep 02 17:42:07 thank you for respushing this idea in my head ;) Sep 02 17:42:13 http://www.newegg.com/Product/Product.aspx?Item=N82E16833124335 Sep 02 17:42:16 sure Sep 02 17:42:23 acidfoo: wired or wireless? Sep 02 17:42:33 wired Sep 02 17:42:37 acidfoo: ah.. Sep 02 17:43:01 I can only give brand recommendations for wireless unfortunately Sep 02 17:43:08 no problem ;) Sep 02 17:43:17 good luck Sep 02 17:43:20 actually I should try too with wireless Sep 02 17:43:36 a dongle as small as possible Sep 02 17:43:44 I moved all of my stuff from wired to wireless and let me tell you... I was a wired fanatic before Sep 02 17:43:52 lol:) Sep 02 17:44:06 so that meant a lot to me for it to work this well Sep 02 17:44:25 3 arm boxes 1 laptop and 1 server Sep 02 17:44:31 heheh Sep 02 17:44:39 :) Sep 02 17:57:52 and anyone have tried a usb-ethernet-adaptor with the beaglebone ? i'd like to hear any suggestion for the device Sep 02 17:57:54 thanks ;) Sep 02 17:59:04 bb or bbb? Sep 02 17:59:17 bbb Sep 02 17:59:34 why not use the built in one? or do you need dual? Sep 02 17:59:49 yes, i'd like to have dual Sep 02 18:00:06 i'll try a wifi-dongle and a usb-ethernet-adaptor Sep 02 18:00:07 ahhh Sep 02 18:00:10 yeah Sep 02 18:00:19 in both case I want to be dual Sep 02 18:00:26 cabled, and wireless Sep 02 18:00:38 I saw that adafruit sell wifi-dongle that work fine Sep 02 18:00:47 now need to find a usb-eth-adaptor that work fine too ;) Sep 02 18:22:18 acidfoo. TI has a devboard with dual GbE Sep 02 18:22:23 #200 Sep 02 18:22:27 $200* Sep 02 18:22:46 wow! that's cheap! Sep 02 18:22:52 not exactly a Beaglebone clone but . ..there ya have it Sep 02 18:24:41 * Tenkawa is tempted to get a cubieboard2 \ Sep 02 18:24:52 dual core, sata... need I say more Sep 02 18:25:03 i think its 69$ Sep 02 18:25:41 i'd get more bbb if I could effectively run sata on it Sep 02 18:26:39 cubieboad 2 last i looked was $49 Sep 02 18:26:56 Tenkawa: cubie and bbb have different target audiences Sep 02 18:27:03 juup Sep 02 18:27:12 cubie == pocket pc Sep 02 18:27:50 bbb== affordable low power ( as possible ) embedded system Sep 02 18:27:50 whys that? Sep 02 18:28:01 m_billybob: its only 20$ more Sep 02 18:28:05 at least here Sep 02 18:28:14 here its only $4 more Sep 02 18:28:29 different target audiences like KotH said though Sep 02 18:28:32 and for what I use arm boxes for (genera purpose servers) I'm starting to look for more horsepower Sep 02 18:28:40 KotH: true Sep 02 18:28:45 also, is cubie still using allwinner ? Sep 02 18:28:49 ye Sep 02 18:28:50 s Sep 02 18:28:52 a20 Sep 02 18:28:58 thats a negative in my book Sep 02 18:29:28 why is that.. (serious q) you're not the first I've heard that from Sep 02 18:29:56 what "would" be a good step up from the bbb for a general purpose arm server? Sep 02 18:30:01 because everythign else ive heard of that has used allwinner in the past was junk Sep 02 18:30:11 I've got 2 rpis and a bbb currently all running slackware Sep 02 18:30:14 i dotn have much faith in electronics made in that region of the planet Sep 02 18:30:20 Tenkawa: if you are looking for a home server replacement, then the bbb is probably not the right choice Sep 02 18:30:21 isnt most... Sep 02 18:30:24 made there? Sep 02 18:30:32 KotH: of course not Sep 02 18:30:34 Tenkawa: neither is the rpi though ;) Sep 02 18:30:50 KotH: I really like arm architecture.. just need something a little more powerful Sep 02 18:30:50 neither is any of the mentioned options IMHO Sep 02 18:30:55 m_billybob: 99% of all electronics is made in china these days Sep 02 18:31:03 I have a quad core x86_64 already as my powerhouse Sep 02 18:31:05 m_billybob: and a big portion of software too Sep 02 18:31:21 m_billybob: and i'm not talking about production, but design too Sep 02 18:31:42 the ouya's hardware looks like it'd be really neat to use linux on heh Sep 02 18:31:45 so you think TI outsources design to china ? ;) Sep 02 18:35:51 anyhow, most of the stuff in the past two years I've read about that used the allwinner processors turned out to be junk. NOt saying every single thing, but enough to get my attention Sep 02 18:36:14 With that said, i would like to get, and toy with a cubieboard Sep 02 18:36:45 make sure if you do to get the 2 Sep 02 18:37:01 $50 is not a whole lot to spend on a mini computer Sep 02 18:37:05 of course. Sep 02 18:37:08 nope Sep 02 18:37:44 i'd be more interrested in it if it had GbE though, even at twice the cost Sep 02 18:38:39 KotH close your eyes . . . Sep 02 18:38:51 * m_billybob is currently attempting to build nodejs on his bbb Sep 02 18:39:07 * m_billybob kicks back and waits for it. Sep 02 18:39:36 * KotH calls elenril to stab m_billybob Sep 02 18:40:34 i'd use snorkle if it were better supported on ARM Sep 02 18:40:52 last i looked it was alpha or beta on armv4 Sep 02 18:42:02 Linux (Debian EABI ARM beta) <---- not even the ABI i need Sep 02 18:44:29 most recent forum post was from a month ago . . . Sep 02 18:44:33 yeah not looking good. Sep 02 18:44:42 hno Sep 02 18:45:18 Tenkawa, I have both bbb and cubieboard2. why do you ask? Sep 02 18:47:28 m_billybob, how is Cubieboard2 and BBB different audiences? Cubieboard2 defenitely is NOT a pocket computer. Just a "dev" board much like bbb. Sep 02 18:48:32 m_billybob: what's snorkle? Sep 02 18:49:22 hno: performancewise is the cb2 a major step up? Sep 02 18:49:40 I want to use a sata ssd Sep 02 18:50:04 is its io decent? Sep 02 18:50:24 cb2 performs quite well, but don't have any hard numbers for you. Spend most my time in u-boot only. Sep 02 18:50:26 hno: the bbb has people who build electronics around a processor as audience, the cubie people who use the board as a standalone system, maybe with some usb/sata devices plugged in Sep 02 18:50:45 hno: ahh. general specs indicate it should be quite the step up Sep 02 18:50:55 KotH C/C++ embedded web server SDK Sep 02 18:51:00 m_billybob: ah.. Sep 02 18:51:02 * Tenkawa grumbles as u-boot Sep 02 18:51:06 er at Sep 02 18:51:07 m_billybob: why not use lighttpd? Sep 02 18:51:14 m_billybob: if you need a webserver that is Sep 02 18:51:18 lighttpd is great Sep 02 18:51:53 KotH, they both have about the same capabilities in expansions with shields, but not that many shields exists for cubieboard yet. Sep 02 18:51:53 KotH I want an embedded webserver, for making a linux appliance. the only thing i know of that can do this reasonably "easy" is nodejs Sep 02 18:52:00 didn't the cool kids all switch to nginx? Sep 02 18:52:06 until that became uncool too, that is Sep 02 18:52:12 mru: who wants to be cool... Sep 02 18:52:17 hno: uhmm.. i'm not an A20 expert, but i would disagree with that statement Sep 02 18:52:17 key word here "embedded" does not mean for embedded hardware Sep 02 18:52:18 why bother.. Sep 02 18:52:27 m_billybob: ah.. ok Sep 02 18:52:32 m_billybob: hack on! Sep 02 18:52:38 m_billyboberr - apache? Sep 02 18:52:54 embedded web server . . . Sep 02 18:53:04 means my application and web server are the same app Sep 02 18:53:10 * Tenkawa would be quite happy with an ARM box designed as a server and not a attachment platforn Sep 02 18:53:10 apache is way too bloated and bizarre to configure for most simple uses Sep 02 18:53:13 Not to most people. Sep 02 18:53:14 er platform Sep 02 18:53:18 KotH, why? Sep 02 18:53:18 i run apache 2 now Sep 02 18:53:35 hno: have you read what the AM3359 can do? Sep 02 18:53:48 hno: it's an industrial control processor, with tons of peripherials integrated Sep 02 18:53:54 hno: not to talk about the PRU Sep 02 18:54:12 the PRU is the icing Sep 02 18:54:22 KotH: the kids these days care only about gpio count Sep 02 18:54:25 hno: while the A20 is an application processor for cellphones and tablets Sep 02 18:54:26 lots of potential hackery in that alone Sep 02 18:54:53 mru: I'd be happier with an arm piece of hardware with no gpio at all Sep 02 18:55:09 Tenkawa cubie may be for you then Sep 02 18:55:10 mru: that's why i teach those kids that gpio count is not everythiing... usually using a lart Sep 02 18:55:16 Tenkawa: calxeda for you then Sep 02 18:55:28 but speaking of hardware.. anyone know a decent motion sensor for bbb or rpi? Sep 02 18:55:31 wanderboard . . . Sep 02 18:55:41 mru: calxeda... hmm let me look that up Sep 02 18:55:45 KotH, in terms of I/O the A20 is built for a wide range of applications, so plenty of I/O that have absolutly no sense in a tablet or phone, depending on what pinmuxing you select. Sep 02 18:55:51 and theres another i forget the name of supposed to blow an i3 out of the water in many benchmarks Sep 02 18:55:57 I doubt there is _any_ motion sensor specifically for either of those boards Sep 02 18:56:03 darn Sep 02 18:56:14 I want to build a garage door sensor Sep 02 18:56:16 most sensors have some standard interface that can be attached to any board Sep 02 18:56:25 Tenkawa: i have recently used a bma250 in a project. looked decent Sep 02 18:56:37 mru, its call an FTDI module ;) Sep 02 18:56:37 bma250.. noted thanks Sep 02 18:56:45 Tenkawa: and unlike VTI devices i've seen sofar, the bma250 behaved like the datasheet said Sep 02 18:57:14 Tenkawa: but be aware that it's a qfn case, which is not easy to solder by hand Sep 02 18:57:23 ooh bosch Sep 02 18:57:49 KotH: fortunately my engineer has extremely precise soldering hands Sep 02 18:57:54 ok.. the VTI are in an MID which melts as soon as you plug in your soldering iron Sep 02 18:58:21 unfortunately that one doesnt have visual sensing Sep 02 18:58:36 I need to add a visual axis sensor for when the door doesnt close Sep 02 18:58:45 KotH, A20 do not have a PRU equivalce. Sep 02 18:59:21 hno: only TI processors have the PRU Sep 02 18:59:25 Tenkawa -> http://www.edn.com/design/diy/4419990/1/The-biggest-little-revolution--10-single-board-computers-for-under--100 Sep 02 18:59:46 KotH: hmm... how about magnet to magnet sebsors Sep 02 18:59:49 er sensors Sep 02 19:00:34 heh calxeda is a bit out of my budget/design Sep 02 19:00:40 Tenkawa: never used one Sep 02 19:00:45 Tenkawa: beside a reed switch Sep 02 19:00:55 KotH, there is other similar solutions in other processors. Even from Allwinner (to some degree) Sep 02 19:01:10 hno: o_0 Sep 02 19:01:15 hno: show me the codes! Sep 02 19:01:17 ooh.. reed switch... completely forgot about those Sep 02 19:01:20 hno: or rather the datasheet Sep 02 19:01:39 Tenkawa: lol Sep 02 19:02:04 Tenkawa: a good design is one where you cannot take away or simplify any component without losing required functionality Sep 02 19:02:19 heheheh Sep 02 19:03:25 * m_billybob waits 5 horus for the build to finish Sep 02 19:03:29 hours too Sep 02 19:04:26 http://26-26-54.hardwarebug.org/167 Sep 02 19:04:33 * Tenkawa is glad to have gis cross compiler Sep 02 19:04:36 er his Sep 02 19:04:46 i have a cross compiler 3 actually Sep 02 19:04:51 (systems ) Sep 02 19:04:58 root@arm:~# uptime Sep 02 19:04:58 12:06:10 up 27 days, 11:59, 3 users, load average: 0.94, 0.48, 0.35 Sep 02 19:05:01 * KotH has cross compiler V4 Sep 02 19:05:24 ah.. you are one of those who reboots his machine once a month! Sep 02 19:05:38 thing is i did not feel like wading through someone elses makefiles Sep 02 19:06:08 KotH no, i finally figured out why my windows box loses network connection - hint it has nothing to do with the windows machine Sep 02 19:06:19 broken switch? Sep 02 19:06:23 KotH, Allwinner A31 have an embedded OpenRISC core for various small realtime tasks. Tegra series of SoCs have an ARM Cortex M core for similar purposes, etc. But only TI is explicit about it and have a clear intent and direction. The others pretty much don't talk at all. Sep 02 19:06:36 i power my bbb via USB so before i was rebooting my windows machine when it would stop takign an ip off the network . . . Sep 02 19:06:40 my crosscompiler is that quadcore 8gb ram box... it is great Sep 02 19:06:47 hno: uhmm.. an OpenRISC core does not give you the same as an PRU Sep 02 19:07:15 KotH turns out its the linux power GbE switch i connect to the network from . . . Sep 02 19:07:22 linux powered* Sep 02 19:07:32 just think if they released enough info to convert the ouya to a standalone linux box Sep 02 19:07:39 hno: OpenRISC does not guarantee you cycle exact execution of code as it uses lots of async stuff in it's system Sep 02 19:08:15 hno: the C-M3 can be done in a way that it can be handled cycle exact, but only the PRU can switch all associated pins at each clock cycle Sep 02 19:08:32 m_billybob: lol Sep 02 19:09:05 Tenkawa: 8gb? who uses that little ram these days (beside the place i work for) Sep 02 19:09:17 KotH: this is my home machine sitting in a closet Sep 02 19:09:30 its only got 8gb because I never bothered to add more Sep 02 19:09:54 KotH, long story short, we're solar powered, we fire up a generator to use the car lift, pump water, or to do welding . . . so when switching back off the genset, we're withotu power long enough to reset all computer systems . . .so best way for me to power my BBB is via a usb3 port on my windows laptop. Sep 02 19:10:22 meaning it'll never lose power Sep 02 19:11:18 m_billybob: oh.. get an APC Sep 02 19:11:26 for the computers at least Sep 02 19:11:48 both of my apcs lost their batteries too soon Sep 02 19:12:02 did you replace them on warranty? Sep 02 19:13:35 KotH: nope.. wasnt thinking about it at the time Sep 02 19:13:44 that was years and years ago Sep 02 19:14:21 * Tenkawa is ancient Sep 02 19:14:30 haahaa Sep 02 19:15:45 KotH not really interrested we already have a 2200aH @12v nominal "UPS" ;) Sep 02 19:16:09 KotH i did however want to eventually design one for the bbb Sep 02 19:17:41 shouldnt be too hard, we have a couple of deep cycle batts layign around, just need a make / buy a step down converter Sep 02 19:18:56 m_billybob: have a look at the "ideal diodes" from linear Sep 02 19:19:10 ideal diodes ? Sep 02 19:19:14 * m_billybob googles Sep 02 19:19:30 chips that control a series fet to make it behave like a diode Sep 02 19:19:49 gives the advantage of a low resistive diode without voltage drop Sep 02 19:20:09 oooo Sep 02 19:20:28 * m_billybob is reading a "propaganda PDF" atm Sep 02 19:21:16 KotH e.g. this -> LTC4354 Negative Voltage Ideal Diode-OR Controller ? Sep 02 19:21:32 thanks for all the info all.. bbl Sep 02 19:21:48 m_billybob: yes, there are positive versions of it too Sep 02 19:22:24 m_billybob: and iirc also some that behave like a single diode Sep 02 19:22:25 yea reading the brocure now Sep 02 19:24:36 still building . . . Sep 02 19:24:46 http://www.youtube.com/watch?v=1lnWS4W490s Sep 02 19:24:51 guess thats a good sign Sep 02 19:24:51 opps Sep 02 19:25:05 wrong chat soz Sep 02 19:34:20 anyone here fiddled a lot with the neon ? Sep 02 19:35:32 im so annoyed that there is no cast from uin8x16_t to uint8x8x2_t Sep 02 19:36:07 forget about the intrinsics Sep 02 19:36:20 they'll drive you mad and the generated code will still suck Sep 02 19:37:52 mru: i think so too Sep 02 19:38:13 although the code is quite fast.. i would think i could asm it faster Sep 02 19:38:37 its mostly simple load shift and shuffle and xor Sep 02 19:38:43 reed solomon simd :) Sep 02 19:39:09 people who talk about 'shuffle' are usually stuck in mmx-think Sep 02 19:39:34 table lookup.. Sep 02 19:39:43 whatevcer Sep 02 19:41:38 anyhow i was wondering to do byte interleaving one would simply load q1 q2 q3 q4 then do some d swapping before using vst4 Sep 02 19:42:24 where q1 - q4 is originally spaced quite far a part in memory Sep 02 19:43:42 mru: it was called shuffle on the cell be spe's too Sep 02 19:44:24 iirc it was capable of the same types of data reordering as the neon is Sep 02 19:44:34 the thing is, neon has things like vldN, vtrn, and vzip Sep 02 19:44:43 you rarely need the full table thing Sep 02 19:44:47 which is rather slow Sep 02 19:45:29 mru: i use the table thing to lookup polynomial multiplication tables for 0xF0 and 0x0F respectively then xor them together for the correct value Sep 02 19:45:48 you know neon has native polynomial multiplication? Sep 02 19:47:35 hmm Sep 02 19:47:47 <- tries to find some data on that subject Sep 02 19:47:54 tried many times before too Sep 02 19:49:11 ARM ARM A2.8 Sep 02 19:49:32 KotH - in regard to your hardwarebug.org link . . . working on two hours now. still not done :/ Sep 02 19:50:02 .o0(BDSM) Sep 02 19:50:09 no kidding.

Sep 02 20:15:33 im using an SSE article from jan 2013 to achieve what we want on neon. Sep 02 20:16:11 m_billybob: nodejs needs various patches to work correctly on ARM, the nodites made a lot of stupid assumptions *and* the v8 buildsystem does the same Sep 02 20:16:40 using 46 bytes parity on 35 bytes of data (dont ask) it encodes at about 31-61 us on 500Mhz Sep 02 20:17:09 syndromes are calculated in about 61.93 us on 500Mhz Sep 02 20:21:47 unsure if there is any simd benefits for Berlekamp-Massey, Chien and Forney Sep 02 20:23:33 http://www.ssrc.ucsc.edu/Papers/plank-fast13.pdf Sep 02 20:27:43 Not to diffucult to adopt it to neon Sep 02 20:30:57 mru: only downside to the sse is that neon needs to do two more table lookups the xor and and is easely done in the 128 bit simd Sep 02 20:32:18 not to forget the shr Sep 02 20:32:31 koen, is there an information link or some such i can look at ?

Sep 02 21:24:34 KotH lol thats my bbb Sep 02 21:25:42 KotH but why peaches ? its my first name, and then "bbb" Sep 02 21:26:06 m_billybob: there are peaches in .ch that are called "williams" :) Sep 02 21:26:23 wouldnt know abotu ch Sep 02 21:26:46 here in the USA we have del monte, and a few other "brands" Sep 02 21:27:22 * m_billybob wipes his bbb clean and starts over Sep 02 21:27:27 lol Sep 02 21:27:38 lets see if i can do all this live without it hiccuping Sep 02 21:27:39 williams is not a brand Sep 02 21:28:25 you know, potatos do not grow in the cellar, neither does come milk in a bottle into existance ;) Sep 02 21:28:54 but there is always a brand name behind them Sep 02 21:29:33 bah guess ill have to shutdown my perdy 28 day uptime bbb :( Sep 02 21:30:01 lol Sep 02 21:30:15 no, most fruits and vegetables have just a farmer behind them Sep 02 21:30:18 no brand at all Sep 02 21:39:13 perhaps that is how it works there. everythign sold here in the US has a brand Sep 02 21:40:16 yeah.. Sep 02 21:40:25 corporate america owns you Sep 02 21:41:40 * KotH wonders how many people would be able to support themselves in case our economy would collapse Sep 02 21:41:52 right here Sep 02 21:42:23 KotH: growing potatoes isn't all that hard Sep 02 21:42:46 we'd have meat here too plus fruit andvegtables Sep 02 21:42:51 it isnt, but how many know it? Sep 02 21:43:08 1) plant potatoes, 2) wait Sep 02 21:43:14 we meaning here on this property Sep 02 21:43:41 mru: can we grow chickens the same way? Sep 02 21:43:51 mru: i wouldnt be surprised if a lot of people dont know where potatos grow Sep 02 21:44:00 prpplague: sure, just plant some eggs and wait Sep 02 21:44:11 in cow poop KotH ;) Sep 02 21:44:14 mru: thanks i'll get right on that! Sep 02 21:44:54 many vegetables are fairly easy to grow Sep 02 21:45:09 but in a total collapse of the economy getting seeds could be tricky Sep 02 21:45:14 mru problem is most are seasonal Sep 02 21:45:32 there are various ways of storing them for the winter Sep 02 21:45:48 mru: and you need a lot of space to grow enough for a person or even a whole family Sep 02 21:46:17 the farmland obviously exists already Sep 02 21:46:48 enough to support everyone without all the fertilizers and other techniques we have today? Sep 02 21:47:09 KotH: enough to support those who know what to do with it :) Sep 02 21:47:16 *g* Sep 02 21:48:38 * KotH needs to learn how to grow vegetables in vitro Sep 02 21:48:49 and how to do that with minimal technology Sep 02 21:48:54 hydroponics? Sep 02 21:49:24 yeah Sep 02 21:50:56 sat here wondering why my bbb kept failignto boot duh ! had no exportfs and the nfs server was stopped DO'H Sep 02 21:51:34 mru: i'm pretty sure that you can grow enough vegetables to feed yourself in a flat with that, but the problem is how to get the energy and fertilizers Sep 02 21:51:55 mru: also, most of the high yield systems are pretty high tech Sep 02 21:52:33 * KotH makes a note to buy a couple of books on that topic Sep 02 21:53:56 in the event of a total collapse of society I think I'd rather head for the countryside Sep 02 21:54:50 mru armv8 adds galois field math to the table.. Sep 02 21:54:59 im on armv7 :( Sep 02 21:56:05 32-bit armv8 adds very little Sep 02 21:56:21 64-bit armv8 is something completely different Sep 02 21:56:51 ahh well its in the completely different segment i think Sep 02 21:57:09 has anyone tried the beagleboard images with qemu? Sep 02 21:58:31 ie these: http://beagleboard.org/latest-images, using the linaro version of qemu Sep 02 21:59:20 are here people that would like to test my project for the BBB? http://beagleboard.org/project/BBBabb/ the project is about ROM booting the BBB from an Android device and flash the internal mmc or a uSD card with the BBB Sep 02 22:00:03 wu i would, however no android device :/ Sep 02 22:00:05 mru: i'd try to make it to .tr Sep 02 22:00:23 wu, i take it you're having good progress now ? Sep 02 22:00:25 mru: much higher chance to survive in a society that has been at the brink of colapse for the past 20y :) Sep 02 22:00:37 wife managed to drive over my padphone2 Sep 02 22:00:54 unsolo, how convient eh ? Sep 02 22:00:56 m_billybob: it`s kinda stable but from my point of view works, i need an external eye to find me some problems Sep 02 22:01:16 wu, did you have to fiddle with RNDIS much ? Sep 02 22:01:23 m_billybob: still the main issue is the android kernel because it does not like OTG from the AM335x Sep 02 22:01:45 m_billybob: problem there also, the Android device has to have in the kernel RNDIS_HOST_DRIVER Sep 02 22:02:06 m_billybob: not really but the phone works as a pad.. at least display is broken new one is ordered up.:) Sep 02 22:02:22 if i don`t have it in the kernel i can`t speak at all with the am335x...don`t know really how RNDIS sets up the connection if it advertises multiple times Sep 02 22:02:42 unsolo: no, there are no new data types in v8 Sep 02 22:02:47 wu ah, i experimented with booting the bbb via RNDIS, with no success - glad to see you seemed to have gotten passed that :) Sep 02 22:03:02 some operations are available on more data types, but that's all Sep 02 22:03:22 m_billybob: it`s not really that that hard to construct the packets that have to be sent to the board Sep 02 22:03:39 you can sneak peak at my rusty, noobish java code Sep 02 22:03:42 mostly 64-bit int and double-precision fp vector ops Sep 02 22:03:55 mru: maybe this is all wrong then Lastly, ARMv8 includes a variety of optional cryptographic instructions, that are intended to complement existing hardware accelerators. ARM opted to focus on AES encryption, the SHA1 and SHA256 hashing algorithms and Galois fields with 16 new instructions. Sep 02 22:04:15 wu, maybe i had g_multi compiled in as a module and that stopped it ? but i did have g_ether compiled in statically Sep 02 22:04:49 wu, i also run debian . .so yes im new to linux dev, so more likely my fault than anythign else Sep 02 22:04:54 m_billybob: don`t know about that, g_ether should have everything you needed for RNDIS. did it advertise correctly in dmesg ? Sep 02 22:05:29 if you get "registered RNDIS " something something in dmesg when you plug in the BBB the connection should be automatically set up by the kernel *from xp i say this* Sep 02 22:05:33 unsolo: what does aes/sha have to do with reed solomon? Sep 02 22:05:35 wu i can look once build-essential finishes installing Sep 02 22:05:58 galois field does.. Sep 02 22:06:10 m_billybob: perfect! now i`m trying to find a way to make it work without RNDIS in the kernel Sep 02 22:06:29 really. id love to read what you did when you're done Sep 02 22:06:38 actually lemme build again the kernel for my galaxy nexus Sep 02 22:07:02 unsolo: there's only one instruction related to that in the v8 crypto extensions Sep 02 22:07:04 my blog is kinda bad...don`t really have skills to say what i`m doing, if so you can bug me on PM anytime you want Sep 02 22:07:08 vmull.p64 Sep 02 22:07:13 the rest is all the same Sep 02 22:07:17 i see Sep 02 22:07:24 wu its all good and yes i may do that Sep 02 22:07:44 wu, if you give me a command log, maybe i cant write it up for you ? Sep 02 22:07:49 i wonder what is the fastest of lookup tables like the paper i posted earlier or doing the full vmull vext Sep 02 22:07:51 i can* Sep 02 22:08:10 m_billybob: command log? like commands you would type and give me output? Sep 02 22:08:24 wu just a text file with every step you took Sep 02 22:08:31 m_billybob: brb a bit, switching to my server Sep 02 22:09:34 m_billybob: ok, i`m here now Sep 02 22:09:53 wu so here this is what i mean Sep 02 22:10:02 mru: guess the only way to know would be to actually compare the two.. Sep 02 22:10:03 looking for a small file . . . Sep 02 22:10:15 unsolo: yes, probably Sep 02 22:10:17 m_billybob: just plug in the BBB while in USB Boot mode and do 'dmesg' to see if the kernel registers the RNDIS driver for the BBB Sep 02 22:10:46 dmesg -l |grep RNDIS would work eh ? Sep 02 22:10:58 mru: but since someone did the sse table thingie and wrote an article about it in 2010-2013 i would guess it to be very fast Sep 02 22:11:05 m_billybob: yep Sep 02 22:11:12 it's even a part of the linux kernel raid6 Sep 02 22:11:13 unsolo: on x86, yes Sep 02 22:11:27 nothing Sep 02 22:11:40 can you do lsusb and see what you have? Sep 02 22:11:52 mru: its using ssse3 so it's not that old.. Sep 02 22:11:58 still x86 Sep 02 22:11:59 wu just the roothub Sep 02 22:12:07 true.. Sep 02 22:12:08 so hmm Sep 02 22:12:15 you sure it`s in USB boot mode ? Sep 02 22:12:20 wu oh i dont have it installed Sep 02 22:12:27 i just reverted my rootfs Sep 02 22:12:29 the kernel should have seen at least the USB device Sep 02 22:12:46 any idea how can i see with what config a kernel has been compiled ? Sep 02 22:13:02 hmm ? Sep 02 22:13:10 mru: if i get to give it all out we can have a go at comparing the two.. Sep 02 22:13:12 ah...found it out :) Sep 02 22:13:17 you askign me if i know how to grep .config ? Sep 02 22:13:31 /proc/config.gz Sep 02 22:13:38 grep -s /path/.config Sep 02 22:13:45 err grep -i Sep 02 22:13:53 yeah silly me...i needed to see my .config for android Sep 02 22:14:29 i still got it wrong lol Sep 02 22:14:52 err grep -i DEFINE_TO_SEARCH_FOR /path/.config Sep 02 22:15:29 m_billybob: you need to RNDIS boot the BBB for some specific project or just curious ? Sep 02 22:15:58 wu, a little of both. I am a tinker by nature, and i am in no big hurry Sep 02 22:16:34 right now i am actually trying to get nodejs compiled on my bbb first try failed Sep 02 22:16:54 npm segfaulted Sep 02 22:17:02 dunno here, don`t like at all js/nodejs or the stuff in that area :D Sep 02 22:17:19 gdb said somethign about unreadable executable Sep 02 22:17:44 wu i need to make a linux appliance, and for what i am doing node.js makes the most sense Sep 02 22:18:33 * vvu|Log is feeling so great when all 16 cores are free to compile a kernel! Sep 02 22:18:49 wu, but as far as RNDIS goes, i was hoping for better network performance, i netboot my bbb Sep 02 22:19:14 mhmh dunno here...anyway it will work at USB speed Sep 02 22:19:21 no idea if it will help me or not Sep 02 22:19:36 what time do you have now until you boot the BBB ? Sep 02 22:20:16 best speeds i have so far iis ethernet nfs for read, but writes the best speeds i have is booting from USB which is around 20MB/s writes Sep 02 22:21:34 wu, aroudn 30 seconds tops i think Sep 02 22:21:34 full boot with rootfs and everything ? Sep 02 22:21:34 i get around 11.9MB/s reads 11.1MB/s writes Sep 02 22:21:34 yes Sep 02 22:21:34 maybe a little longer i have not timed it Sep 02 22:21:34 that's about as fast as the ethernet goes Sep 02 22:21:47 mru, i know i was very impressed with the ethernet on this Sep 02 22:21:50 until the kernel to be booted i have like 15 seconds or so Sep 02 22:21:58 m_billybob: it's not usb, that's why Sep 02 22:22:29 but can be done faster...musb and ehci both have serious bugs in the android kernel and i`m restricting the transfer speed Sep 02 22:22:32 mru well even with an intel networkign adapter in the past the best ive done on a PC was just over 100MB/s Sep 02 22:22:47 err 10.6MB/s Sep 02 22:22:55 is the best ive done on x86 ever Sep 02 22:23:07 server grade adapters and all Sep 02 22:23:25 GbE is faster of course Sep 02 22:23:37 depends on quality of switches too Sep 02 22:24:03 well i do have a GbE switch between my PC and the bbb Sep 02 22:24:22 probably not a very good one but good enough to give decent speeds at 10/100 Sep 02 22:24:44 ok so i was going ot show wu what i meant Sep 02 22:24:58 labelled speed ain't everything Sep 02 22:27:01 wu so this is what i do when i do something new and I want to document it ->http://pastebin.com/tPZHVKXD Sep 02 22:27:19 I write every command ( copy paste ) that i do from the cmd line Sep 02 22:27:35 * mru notes that m_billybob has either crummy fonts or crummy eyes Sep 02 22:27:36 btw i dont think that command text file is complete so dont expect too much out of it Sep 02 22:28:23 mru, both. Sep 02 22:28:36 and a broken tab key Sep 02 22:28:58 wu, anyhow, what I was saying is that if you give me soemthign like that, i can most likely write a guide for you Sep 02 22:29:01 if yo uwant Sep 02 22:29:33 mru, notepad doesnt work very well Sep 02 22:29:37 thx for the help but it`s kinda preety straight forward for my project Sep 02 22:29:48 just hacking the kernel is tricky :) Sep 02 22:29:53 lol Sep 02 22:29:54 the user needs to hack its own kernel Sep 02 22:29:56 all good Sep 02 22:30:15 notepad? Sep 02 22:30:22 windows . . . Sep 02 22:30:26 m_billybob: also i have a semi linux port of usb booting the am335x Sep 02 22:30:33 you somehow run irc in notepad? Sep 02 22:30:37 when i make a command log of what i do i just use notepad Sep 02 22:30:49 with a part of libusb *speaking* with the chip Sep 02 22:30:50 mru, what are you talking about ? Sep 02 22:31:00 you keep referring to vvu|Log as 'wu' Sep 02 22:31:23 mru because i dont use tab complete most of the time Sep 02 22:31:47 those are two 'v' not a 'w' Sep 02 22:32:03 c'mon it`s not a big deal Sep 02 22:32:21 of course it's not Sep 02 22:32:30 wu -> http://www.embeddedhobbyist.com/debian-tips/beaglebone-black/beaglebone-black-usb-boot/ Sep 02 22:32:36 * vvu|Log is just a humble GSoC student Sep 02 22:32:37 ive already written one :) Sep 02 22:32:44 * prpplague hands out knives and welcomes everyone to Beagle-Dome Sep 02 22:33:11 most irc clients highlight mentions of your nick Sep 02 22:33:14 mru ok now that makes sense sorry vvu Sep 02 22:33:20 but only if spelt correctly Sep 02 22:33:27 spelled ? Sep 02 22:33:41 * vvu|Log hates his iMac..fans are running wild here Sep 02 22:33:53 queens versus jersey english bashing time ? Sep 02 22:33:59 * m_billybob giggleas Sep 02 22:34:02 giggles too Sep 02 22:34:22 m_billybob: but still u need uSD inserted and just mount the HDD as rootfs Sep 02 22:34:35 my plan is to do it raw style with nothing attached to the board Sep 02 22:34:41 just hook em up and magic happens Sep 02 22:35:15 vvu yeah all the uboot stuffs needs to be present on a sd card Sep 02 22:35:22 for my way there Sep 02 22:35:41 MLO uEnv.txt u-boot.img Sep 02 22:36:21 vvu, that will be cool though id like to read about that sometime too Sep 02 22:36:45 it`s happening right now Sep 02 22:36:57 see, you can tell me exactly ow to do it, and it will work, but i like reading about HOW people do things more than just getting them done Sep 02 22:37:14 but i need some testers..i`m planning after GSoC finishes i want to port everything to linux Sep 02 22:37:25 im still new to linux dev, so anything likethat i can read helps me a lot Sep 02 22:38:06 don`t worry same story here Sep 02 22:38:53 i spent a whole week learning how uboot -> uEnv.txt file works, just by reading other peoples uEnv.txt files Sep 02 22:39:07 finally sank in hehehe Sep 02 22:39:57 then robert nelson linked me to one of the uboot header files, which i had not seen yet, and then everything for the most part became perfectly clear Sep 02 22:41:17 vvu, anyhow yes, would very much like to read how you did it someday. Sep 02 22:41:44 m_billybob: no problem when everything finishes i will make a good readme Sep 02 22:41:52 and link everybody to it Sep 02 22:41:59 thanks :) Sep 02 22:42:39 m_billybob: yw Sep 02 22:44:23 i think i have your blog bookmarked too but my bbb bookmarks are a total mess, i need to organize them sometime Sep 02 22:44:44 i probably have aroudn 150 beaglebone related bookmarks Sep 02 22:55:02 anybody knows how RNDIS behaves when cable is plugged in? Does it advertises once or multiple times ? Sep 02 22:56:12 one win7 it justcomes up once as far as i know Sep 02 22:56:20 on win7 x64* Sep 02 22:56:26 i`m interested about low level connection set up Sep 02 22:56:40 that i know nothing about Sep 02 22:56:54 Tartarus: ping Sep 02 22:58:02 so in about two hours ill have nodejs built for the second time. hopefully this time npm works right Sep 03 00:56:44 Hi I try to reinstall Angstrom on my Beagle Bone Black and im following the steps on the http://circuitco.com/ wiki and after the 45 min execution approximativly the four leds are on steady and then I remove the power plug and the micro SDcard and when im rebooting the BBB it don't show up as the factory installed it much more as a terminal prompt did i have made a mistake or its normal ? thanks in advance and sorry for this noob q Sep 03 01:32:01 so instructions i found worked awesome Sep 03 02:14:34 moooo **** ENDING LOGGING AT Tue Sep 03 02:59:58 2013
