Aug 21 03:30:52 oh hmmm Aug 21 03:32:09 groups been depressing the last couple of days. Aug 21 04:07:40 is there a way to install a new OS on the built in beagle board black flash memory without owning an sd card? Aug 21 04:08:12 *beagle bone black Aug 21 04:08:30 Tecnically yes, but it would involve using a USB hard drive or flash drive Aug 21 04:08:51 whcih would need to contain am image and boot media Aug 21 04:08:56 an image* Aug 21 04:09:01 bootable* Aug 21 04:09:07 ok Aug 21 04:09:19 what about tftp? Aug 21 04:09:20 juul, any particular distro in mind ? Aug 21 04:09:28 you can boottftp too Aug 21 04:09:32 yeah debian! Aug 21 04:09:37 its what i do now Aug 21 04:09:52 i been Robert Nelsons kernel Aug 21 04:09:55 boot* Aug 21 04:10:03 * m_billybob cant type to save his life tonight Aug 21 04:10:21 I boot both USB and TFTP/NFS rootfs Aug 21 04:11:16 juul, however this most certainly will involve either gettign everything exactly right the first time or the need for a serial debug interface Aug 21 04:12:10 juul -> http://www.embeddedhobbyist.com/debian-tips/beaglebone-black/beaglebone-black-usb-boot/ i also have a guide for setting up tftp etc too on the same home site Aug 21 04:12:10 oh? i'd expect uboot tftp server to work even if the bootable partition is borked Aug 21 04:12:58 well, so lets say you get your uEnv.txt just one parameter wrong. what are you going ot do then ? since you have no sd card . . . that would involve tappign into uboot *somehow* Aug 21 04:13:38 ah Aug 21 04:13:40 the only way i can think of right now would be the serial debug interface Aug 21 04:13:57 or using a sdcard Aug 21 04:13:59 i was expecting that I'd just hold down a button while booting and it'd go into "send me a file and i'll flash it" tftp mode Aug 21 04:14:05 like some routers Aug 21 04:14:19 no no, you can setup an sdcard to avoid that too. pressing S2 Aug 21 04:14:28 hm Aug 21 04:14:39 no need as long as you have a properly setup uEnv.txt file Aug 21 04:14:47 hm Aug 21 04:15:40 you can read the guides i have there, but personally i think i did a better job on the USB booting guide for the purpose if "instructing" how everything works Aug 21 04:16:15 ok cool, thanks! Aug 21 04:17:19 no problem. Aug 21 04:25:58 * mranostay beer shakes in Aug 21 04:26:11 you're late Aug 21 04:26:15 !

Aug 21 09:40:27 "target lost" Aug 21 09:40:42 which target ? Aug 21 09:42:40 hi Aug 21 09:44:27 i beagle board black which kernal source r u using it is linux 3.2 or 3.8 Aug 21 09:45:28 anyone here who knows how to set up eclipse for gdb+openocd? i'm lost in all those hundreds of howtos that do not work. any pointer how that is supposed to work so i can figuring out myself would be fine Aug 21 09:50:03 i cant get u Aug 21 09:51:32 sukesh: modified koen rule #3: check it Aug 21 10:09:09 koth ping Aug 21 10:09:17 * KotH pongs Aug 21 10:09:22 koth gdb is easy Aug 21 10:09:26 in eclipse Aug 21 10:09:52 hmm... Aug 21 10:09:56 just install c/c++ tools Aug 21 10:10:05 and you have gdb debug option Aug 21 10:10:06 maybe i should try first a non-cross compile application Aug 21 10:10:17 eclipse... easy... does not compute Aug 21 10:10:30 second you can install cmake/autotools support Aug 21 10:10:39 mru it is easy with marketplace Aug 21 10:10:50 wtf Aug 21 10:10:54 4.2 is running nice Aug 21 10:11:34 koth but you need openocd for jtagging right? Aug 21 10:11:38 yes Aug 21 10:11:57 there are dozens of howtos on the net how to do that, but none works with 4.2 Aug 21 10:12:15 and of course none explain what they are doing, just providing #exactsteps, so i have no clue what to set where Aug 21 10:12:22 random howtos never work Aug 21 10:12:33 * KotH is currently digesting the eclipse documentation to see what it is doing Aug 21 10:12:47 why are you trying to use eclipse in the first place? Aug 21 10:13:00 * das has already digested eclipse, it's now a huge pile of ... Aug 21 10:13:12 because $coworker do not like vi or emacs Aug 21 10:13:15 or who are you, and what did you do with KotH?

Aug 21 10:21:35 beside being older Aug 21 10:23:45 woglinde: I heard kepler was broken and unfixable Aug 21 10:23:54 mru hm? Aug 21 10:23:58 mru for what? Aug 21 10:24:08 c/c++ and java woth maven is working Aug 21 10:24:22 I need nothing more Aug 21 10:24:23 i can vouch for kepler + cdt + arm-angstrom cross compilation. works just fine Aug 21 10:24:41 Any Mono users here? Aug 21 10:25:02 http://kepler.nasa.gov/news/nasakeplernews/index.cfm?FuseAction=ShowNews&NewsID=292 Aug 21 10:25:16 "the Kepler Space Telescope team is ending its attempts to restore the spacecraft to full working order" Aug 21 10:27:52 Just wrote a library to use the GPIO pins with Mono, but I am wondering if there is a simple way to debug C# code. Aug 21 10:28:17 delete it Aug 21 10:28:29 Setting breakpoints and walk though the code step by step Aug 21 10:28:43 Would make it al lot easier to fix things ;-) Aug 21 10:28:45 that's not how you debug efficiently Aug 21 10:29:02 mru > So, what would you propose? Aug 21 10:29:07 stare at code Aug 21 10:29:19 How to debug effeciently Aug 21 10:29:30 yes, stare at the code Aug 21 10:29:43 Staring at code does not fix bugs Aug 21 10:29:50 indeed Aug 21 10:29:56 add "thinking" Aug 21 10:30:03 writing good code, execute it and streamline does Aug 21 10:30:05 if you stare at it long enough, the bugs give up Aug 21 10:30:26 streamline? Aug 21 10:30:29 KotH: up for a staring contest? Aug 21 10:30:35 add racing stripes? Aug 21 10:30:54 mru: does this apply to HW as well ? Aug 21 10:31:11 Maybe not the most correct expression, "improve" is maybe better Aug 21 10:31:20 das: I'm not a hw designer, but I would assume it does Aug 21 10:31:57 Yes, setting GPIO ports in an optimal way Aug 21 10:32:51 mru > how would you debug code? Aug 21 10:32:59 apart from staring at it :-) Aug 21 10:33:03 stare at it until the bugs run away Aug 21 10:33:25 printf is useful too Aug 21 10:34:38 printf is soooooooooooooooooo 1970 Aug 21 10:34:52 does it matter how old it is? Aug 21 10:35:07 hammers are so 10000 B.C. Aug 21 10:35:08 the wheel is thousands of years old Aug 21 10:35:17 Yes, especially when there are better ways Aug 21 10:35:22 breakpoints, Aug 21 10:35:29 stack traces Aug 21 10:35:38 watched variables Aug 21 10:35:58 but those are not better ways Aug 21 10:36:16 The wheel is being reinvented too. In 1900 or so, they invented the inflatable tire Aug 21 10:36:34 Yes they are so much better. Aug 21 10:36:49 why do you ask if you already know all the "answers"? Aug 21 10:36:52 printf is working Aug 21 10:37:09 breakpoints and step through code is even better Aug 21 10:37:17 you're funny Aug 21 10:37:36 My question is: did someone has this working on the BB Aug 21 10:37:51 what? Aug 21 10:37:59 gdb works fine Aug 21 10:38:04 Setting breakpoints in Mono Aug 21 10:38:12 isnt that a #mono question? Aug 21 10:38:15 mono works on arm Aug 21 10:38:26 so whatever works in mono works Aug 21 10:38:33 but isn't mono rather dead? Aug 21 10:38:53 no Aug 21 10:39:11 says who? miguel? Aug 21 10:39:22 Mono is absolutely not dead and keeps following .NET very close in it's implementation Aug 21 10:40:08 av500 : No, it's a BB question, because I don't know if GDB is available for the BB Aug 21 10:40:08 hm to find bugs you make formal verification for each line of your code Aug 21 10:40:15 BennieBoy: it is Aug 21 10:40:24 gdb runs on arm Aug 21 10:40:24 That's wonderfull :-) Aug 21 10:40:26 woglinde: you prove the correctness of the code Aug 21 10:40:40 dont we all do that for every single line we write? Aug 21 10:40:49 woglinde> where there is code, there are bugs Aug 21 10:40:51 5 seconds to google would have tell you that gdb works on arm Aug 21 10:41:21 woglinde: get faster internet Aug 21 10:41:23 Did not know gdb existed Aug 21 10:41:27 but it would have been less entertaining for us Aug 21 10:41:28 ah Aug 21 10:41:29 I am a .NET developer Aug 21 10:41:35 just got my BBB Aug 21 10:41:36 and of course test driven development Aug 21 10:41:40 how does one debug .net? Aug 21 10:41:46 visual studio Aug 21 10:41:49 and I have no idea if gdb can debug mono Aug 21 10:41:49 delete and rewrite in a real language Aug 21 10:41:59 again, try #mono Aug 21 10:42:03 you only 5 gig to install Aug 21 10:42:06 +need Aug 21 10:42:07 .net is debugged like on gdb, but by clicking stuff Aug 21 10:42:12 mru > which language are you reffering too?

Aug 21 10:43:32 BennieBoy: he is trolling you Aug 21 10:43:36 there, spoiled it again Aug 21 10:43:38 I know ;-) Aug 21 10:43:56 what I said about debugging was absolutely not trolling Aug 21 10:43:58 av500 boooooooooohhhhhhhhhhhhhhhh Aug 21 10:44:02 it's exactly how I work Aug 21 10:44:24 mru > if that is true, then I wish you luck with large projects Aug 21 10:44:54 you can thank me next time you use, well pretty much anything Aug 21 10:45:24 mru you patched windows?

Aug 21 11:00:44 I have Aug 21 11:00:46 I have no idea what it is, but the acronym is cool Aug 21 11:00:48 It is very nasty Aug 21 11:00:55 mru routing protocol Aug 21 11:00:55 I prefer C# Aug 21 11:01:29 used by wireless community in germany Aug 21 11:04:25 ah, mech notworking Aug 21 11:04:28 mesh Aug 21 11:04:37 * ogra_ only ever wrote funny applications in javascript ... Aug 21 11:04:43 all that seriousness Aug 21 11:04:54 * KotH stares at mru's bugs until they run away screaming JIHAD Aug 21 11:04:58 * mru only ever wrote one-line mouseover triggers in javascript Aug 21 11:05:27 were it serious mouse triggers ? Aug 21 11:05:45 mru: batman is a wireless mesh service working over 802.11.... barely works Aug 21 11:06:01 mru: it's very instable and routing convergence takes minutes even in a 5 node network Aug 21 11:06:05 that's how mesh networks work Aug 21 11:06:08 barely Aug 21 11:06:35 maybe they should spent more time on the algorithms and less on the acronym Aug 21 11:06:47 actually, there are tons of algos around Aug 21 11:06:47 actually you can write javafx3d apps in javascript Aug 21 11:06:56 but people do not care about reading a dozen or so research papers Aug 21 11:07:03 they just implement the first naive idea they have Aug 21 11:07:16 and thus is born lennartware Aug 21 11:07:20 juup Aug 21 11:07:47 ++ Aug 21 11:08:02 and ubuntuware Aug 21 11:08:09 heh Aug 21 11:08:16 mru: $customer of us does a wireless sensor network with >100 nodes distributed over about a km^2. it works, it's stable, and even survives massive los of nodes Aug 21 11:08:44 oh.. and those nodes cannot be reached for only a couple of weeks during summer... if at all Aug 21 11:08:46 somehow the mesh at the holiday site worked this year Aug 21 11:08:51 last year it didnt Aug 21 11:08:57 but maybe they wired the nodes :) Aug 21 11:08:58 er.. modulo english grammar Aug 21 11:09:08 av500: you go to the same place every year? Aug 21 11:09:14 sometimes Aug 21 11:09:22 ah yes, that's what families with kids do Aug 21 11:09:40 Look into XBee, wireless mesh network. Works like a charm Aug 21 11:09:44 note to self: don't get kids Aug 21 11:09:57 mru: nothing forces you to go to same place Aug 21 11:10:28 mru: kids aint bad, as long as you can give them back in the evening ;) Aug 21 11:10:53 sure Aug 21 11:14:56 BennieBoy Xbee is the hw, but what protocl are they using Aug 21 11:15:15 woglinde: zigbee defines meshing Aug 21 11:15:15 reactive proactive hybrid? Aug 21 11:15:22 part of the spec Aug 21 11:15:37 av500 *sigh* mesh is like realtime Aug 21 11:15:45 no Aug 21 11:15:48 as said Aug 21 11:15:48 wogline > you are right: Zigbee Aug 21 11:15:53 zigbee defines a meshing Aug 21 11:15:56 look it up Aug 21 11:15:56 Still works quite well Aug 21 11:16:08 woglinde: hard mesh Aug 21 11:17:12 The 802.15.4 standard is primarily aiming at monitoring and control applications Aug 21 11:17:16 nice try Aug 21 11:17:23 ? Aug 21 11:18:40 av500 there is this realtime and that realtime Aug 21 11:18:46 so? Aug 21 11:18:50 there is a zigbee spec Aug 21 11:18:59 if you want to know about zigbee meshing, read it Aug 21 11:19:10 how does that relate to real time? Aug 21 11:19:33 It does not relate Aug 21 11:19:40 usage and what you want Aug 21 11:19:50 hmm Aug 21 11:20:05 wogline > exlplain yourself if you wnat Aug 21 11:20:06 can not compare batman with mesh zigbee Aug 21 11:20:06 wnat Aug 21 11:20:08 woglinde: bahnhof Aug 21 11:20:59 BennieBoy I do not want zigbee Aug 21 11:21:14 I wondered why you mentioned it with batman releated Aug 21 11:21:31 woglinde: did you think real and hard about that? or is that just a soft decision? Aug 21 11:22:48 Zigbee can make use of a mesh topology Aug 21 11:22:53 av500: zigbee mesh is a rather simplified and curde form of a mesh network Aug 21 11:22:58 we were talking about mesh, not BATMAN Aug 21 11:23:12 KotH: I never argued it was not Aug 21 11:23:21 av500: but kudos to them for reducing the complexity before attempting to standardize something that would for sure fail Aug 21 11:23:30 I just said it's in the spec Aug 21 11:23:35 juup Aug 21 11:23:53 hm tpm 2.0 for the nsa win Aug 21 11:24:05 but the problem zigbee mesh solves does not compare to the one batman tries to solve Aug 21 11:24:17 it's like comparing a sand castle to a space station Aug 21 11:24:38 I think BATMAN and Zigbee are not really related in their usage Aug 21 11:24:54 BennieBoy: o rly? Aug 21 11:25:04 BennieBoy: why did you mention zigbee mesh in the first place then? Aug 21 11:25:14 Koth > but it is still mesh ;-) Aug 21 11:25:20 a nice koth understood me Aug 21 11:25:25 and that was wat triggerd Zigbee Aug 21 11:25:33 woglinde: nice? me? JIHAD! Aug 21 11:25:34 ;-) Aug 21 11:25:35 it can be a working Mesh network Aug 21 11:26:14 * KotH pats BennieBoy on his head Aug 21 11:26:22 there, have a cookie and go play somewhere else Aug 21 11:26:55 Anyone working with Zigbee over here? Home automation? Aug 21 11:27:04 Koth > thanks, needed that one ;-) Aug 21 11:27:14 * KotH did, didnt like it, moved on to greener pastures Aug 21 11:33:30 av500 > do you use mono? Aug 21 11:34:47 no Aug 21 11:34:52 I prefer stereo Aug 21 11:35:00 <__dumb> i want to start with linux on embedded devices. i have tried alot but no success. everything googled is going over my head. i can read a 500 pages but i want basics at one place. i know msp430 and want to go further with os and linux. help me Aug 21 11:35:51 read a book Aug 21 11:35:53 I prefer 5.1, but stereo ain't that bad ;-) Aug 21 11:36:01 500 pages is nothing Aug 21 11:36:04 __dumb: try "embedded linux primer" Aug 21 11:36:07 +1 Aug 21 11:36:12 __dumb: it's a bit dated, but it's a good book Aug 21 11:36:23 __dumb: oh.. and you need to have a very sound linux knowledge Aug 21 11:36:34 __dumb: using ubunto will not cut it Aug 21 11:37:12 __dumb, what will be your usage? Aug 21 11:37:14 deja vu anybody? Aug 21 11:37:21 av500: ? Aug 21 11:37:32 av500: beside getting this question at least once a week? Aug 21 11:37:39 Just want to learn, or are you going to use it in a certain way? Aug 21 11:38:14 <__dumb> KotH: tried emb linux primer. Aug 21 11:38:20 KotH: more like re-asking in hope to get another, better answer Aug 21 11:38:25 see Aug 21 11:39:31 * KotH looks Aug 21 11:39:51 <__dumb> BennieBoy: develop a mobile phone (non-smart phone firmware) and a standalone embedded webserver (with php) with mmc as fs (these two idea are currently in my mind) Aug 21 11:40:36 __dumb: tried and? Aug 21 11:41:16 av500: prolly got confused Aug 21 11:41:19 <__dumb> av500: and got a little idea but not able to start (for real) but it did help me understand some concept Aug 21 11:41:22 __dumb > those seem to be though goals you give yourself. However, the stand alone embedded webserver is not that difficult Aug 21 11:41:42 av500: embedded linux primer is steep hill to climb if you dont know linux very well Aug 21 11:41:53 well, there are tons of book about linux Aug 21 11:41:58 * KotH nods Aug 21 11:42:14 so, I dont see the point reiterating it all over again Aug 21 11:42:21 Than again, why write a embedded webserver if you can take one from the shelf. Better concentrate on the PHP Aug 21 11:42:22 __dumb: read, read and read Aug 21 11:42:22 I wonder if I should read a linux book... Aug 21 11:43:04 I wonder if I ever did read a linux book. Started on Solaris right away Aug 21 11:43:09 is not linux Aug 21 11:43:14 hm for a small embedded webserver I reccomend cppcms Aug 21 11:43:20 php is not small Aug 21 11:43:21 But smells like it ;-) Aug 21 11:43:25 woglinde: that is beside the point Aug 21 11:43:38 he is starting from zero knowledge Aug 21 11:43:52 debating php vs js is the least of his worries Aug 21 11:43:58 av500 yes and I give him something to look up Aug 21 11:44:17 __dumb: read the book again Aug 21 11:44:22 then get a book on linux Aug 21 11:44:28 and install linux on your PC/laptop Aug 21 11:44:30 while true; do { echo -e 'HTTP/1.1 200 OK\r\n';cat index.html; } | nc -l 8080; done Aug 21 11:44:31 BennieBoy: it might be rude to say, but that you didnt read is clearly visible from the things you write Aug 21 11:44:32 play with it Aug 21 11:44:36 embedded webserver :) Aug 21 11:44:45 ogra cheater and stealer Aug 21 11:44:54 woglinde, spreader :P Aug 21 11:44:54 like anything else, it takes 10000h to do it right Aug 21 11:45:04 Koth > ? is that true? Aug 21 11:45:08 yes Aug 21 11:45:11 av500 years is better Aug 21 11:45:17 What makes you say that Aug 21 11:45:17 BennieBoy: yes Aug 21 11:45:22 experience Aug 21 11:45:23 woglinde, ++ Aug 21 11:45:37 experience in what? Aug 21 11:45:43 people Aug 21 11:45:52 facts please Aug 21 11:45:58 <__dumb_> i was a php dev earlier and nearly always work on GNU/Linux Aug 21 11:46:07 lol Aug 21 11:46:28 woglinde: want some popcorn for the show? :) Aug 21 11:46:29 this channel depresses me :( Aug 21 11:46:33 Vaizki: why? Aug 21 11:46:42 Vaizki I thought it was the lack of sun Aug 21 11:46:45 Vaizki: too many n00bs who think youtube is the way to learn things? Aug 21 11:46:46 in .fi Aug 21 11:47:10 I do not have the fortitude to endure the zombie masses of "I don't know shit but I want it all - now" people Aug 21 11:47:33 woglinde: no lack of sun here for the last 4 months or so, I'm in a GREAT mood ;) Aug 21 11:47:33 __dumb_: your php knowledge is mostly useless for embedded systems, and might be even a disadvantage Aug 21 11:47:50 <__dumb_> i want to understand the working on internally whats going on, Aug 21 11:47:52 __dumb_: unless you have some serious sysadmin experience, having worked on "GNU/Linux" doesn't say anything Aug 21 11:48:08 __dumb_: then do it Aug 21 11:48:09 __dumb_: 13:42 < av500> __dumb: read, read and read Aug 21 11:48:12 +1 Aug 21 11:48:17 also, read, read and read Aug 21 11:48:19 __dumb_: try, read, try, read, try, read, understand Aug 21 11:48:23 unscrew the box, look inside Aug 21 11:48:24 explore Aug 21 11:48:27 be curious Aug 21 11:48:27 <__dumb_> im reading, reading, read Aug 21 11:48:31 well ... some practice comes in handy as well Aug 21 11:48:32 do NOT look for a silver bullter Aug 21 11:48:35 do NOT look for a silver bullet Aug 21 11:48:38 there is none Aug 21 11:48:52 __dumb_: for reference: it took me 2 years of serious exploring linux to get anywhere Aug 21 11:48:54 Read and use. Aug 21 11:48:57 Not only read Aug 21 11:49:01 experience Aug 21 11:49:09 and facts Aug 21 11:49:10 :) Aug 21 11:49:14 crappy dsl line Aug 21 11:49:14 can we flay him now? Aug 21 11:49:15 install 50 different linux distros and learn .... Aug 21 11:49:16 __dumb_: like >5h of digging into low level systems every day Aug 21 11:49:24 read, use, experience and facts? Aug 21 11:49:50 <__dumb_> i have also worked on msp430 but im unable to realted things Aug 21 11:49:56 <__dumb_> *relate Aug 21 11:49:57 ? Aug 21 11:50:04 __dumb_ what you want to understand? you do not need embedded in understanding how the linux kernel works or a compiler Aug 21 11:50:05 it's a good idea to understand how the linux kernel works, what it does and how it starts up Aug 21 11:50:05 It is a iterative process, read, use, read more, use, read even more, use, etc Aug 21 11:50:31 no need to read up anything on user space, programming languages, apis etc until you know how the heart beats Aug 21 11:50:36 Vaizki, it is also good to understand the plumbig userspace :) Aug 21 11:50:42 *plumbing Aug 21 11:51:00 and if you want to have a UI it is also good to know how that stuff works Aug 21 11:51:07 plumbing userspace? Aug 21 11:51:10 Do you need to to know how a car works when you want to drive one? Aug 21 11:51:16 yes Aug 21 11:51:27 Vaizki, the layer that makes your UI talk to the kernel :) Aug 21 11:51:30 <__dumb_> Vaizki: hum ok! Aug 21 11:51:33 if you want to drive a raspberry pi sure Aug 21 11:51:36 don't learn it Aug 21 11:51:41 so it depends what you want for the need of understanding everything Aug 21 11:51:43 (and keeps the machinery running in the background) Aug 21 11:51:49 BennieBoy: every changed gears without pressing the clutch and wondered whats going on? Aug 21 11:52:19 woglinde1: i think you need to run bnc somewhere stable Aug 21 11:52:26 I know what is going on, but that is beside the point. 99% of drivers just drive. Aug 21 11:52:36 Same for computer users Aug 21 11:52:49 And yes, you need to know more on an embedded system Aug 21 11:52:52 ok ok I get the car analogy. users, cars and this channel is the dealership repairshop where people who put gasoline into diesel engines come and complain Aug 21 11:53:02 but do you have to know all the ins and outs? Aug 21 11:53:06 ARGH! what a FUCKING IDIOT! Aug 21 11:53:09 don't think so Aug 21 11:53:25 yea let's talk about cars for a day Aug 21 11:53:37 woglinde1: the reason why gdb doesnt work is, because the CDT installed on this system does not match the installed eclipse version, giving nice errors Aug 21 11:54:17 Koth > and that is why you need to know all the plumbing? Aug 21 11:54:30 oh, cars nice ! I have a renault, I know all about fixing them ! Aug 21 11:55:06 BennieBoy: uh.. are you seriously asking this question? Aug 21 11:55:21 das: not a 2cx? Aug 21 11:55:32 What am I ? A nun ? Aug 21 11:55:46 +1 Aug 21 11:55:52 if you want to do embedded linux without understanding the plumbing, you can pay KotHs company to fix it for you Aug 21 11:56:02 just like you can pay your car repair shop Aug 21 11:56:18 Yes, __dumb wants to do something in PHP and wants to know more about embedded systems, but to say that he/she can only reach his goal by knowing everything about everything what happens on an embedded system is overkill Aug 21 11:56:49 <__dumb_> BennieBoy: He :) Aug 21 11:56:56 the thing is, he does not know what he wants Aug 21 11:57:09 BennieBoy: he said "develop a mobile phone (non-smart phone firmware) and a standalone embedded webserver (with php) with mmc as fs" Aug 21 11:57:21 sounds like buzzword bingo to me Aug 21 11:57:27 <__dumb_> actually i know what i want but that has a very steep learning rate Aug 21 11:57:31 aka "he does not know what he wants" Aug 21 11:57:36 __dumb_: so? Aug 21 11:57:41 that is not the same as installing ångström and putting a few php files in the web server root Aug 21 11:57:42 Than, that is the answer to tell him. Just make up your mind how you want to use an embedded system before asking the question Aug 21 11:57:42 BennieBoy: well, i want a space station, what for do i need to know how to build a rocket? Aug 21 11:58:01 BennieBoy: i just want a space station, no need to know about solar panels or how to deal with vacuum Aug 21 11:58:03 just use AmazonPrime Aug 21 11:58:10 they can deliver it Aug 21 11:58:31 <__dumb_> three thing that makes me shiver is bootloader and linux and rootfs | i m trying to get their concepts how, why and where Aug 21 11:58:31 Spacex.com Aug 21 11:58:35 they actually have prices Aug 21 11:58:38 indiegogo .... Aug 21 11:58:39 :) Aug 21 11:59:09 __dumb_: read up on how linux booting works on x86 Aug 21 11:59:09 __dumb_: http://free-electrons.com/ Aug 21 11:59:14 loadsa docs here Aug 21 11:59:20 __dumb_: there are a few webpages that describe that in detail Aug 21 11:59:22 lotsa docs everywhere Aug 21 11:59:31 __dumb_: when you know that, it's easy to apply that knowledge to embedded systems Aug 21 11:59:32 thing is, he is not reading them Aug 21 11:59:41 the free-electrons material is really simple IMHO Aug 21 11:59:52 whereas kernel Documentation/ ... Aug 21 11:59:59 das: is easy as well Aug 21 12:00:11 das: you just need to think like a kernel developer Aug 21 12:00:18 das: not like a user space developer Aug 21 12:00:25 __dump: Start giving yourself a goal which is feasable with your current knowledge and build from there Aug 21 12:00:58 __dumb_: breadth first. understand the whole chain. then study the parts enough to know the principles. then you know where to look for more later. Aug 21 12:01:05 KotH: noobs can't udnerstand kernel doc, you need a knowledge base first Aug 21 12:01:13 hm at least he is not writing a master thesis Aug 21 12:01:18 lol Aug 21 12:01:27 das: not true Aug 21 12:01:29 woglinde: you dont know that Aug 21 12:01:45 av500 he what have already told us Aug 21 12:01:52 das: i was a bloody n00b when i read my first kernel docs Aug 21 12:01:54 <__dumb_> no, not writing master thesis :D Aug 21 12:01:55 he might be tricky Aug 21 12:02:02 das: i didnt even own a computer for more than a month or so Aug 21 12:02:14 das: i read it, and i understood most of it Aug 21 12:02:23 and you leave php very fast when learning some concepts at university Aug 21 12:02:38 das: ok... i didnt try to get spi working on a embedded system Aug 21 12:03:33 KotH: there's tons of good stuff around: FE, OSdev ... no reason to start with kernel doc Aug 21 12:03:47 das: there were none of those back then ;) Aug 21 12:04:09 rtfs always worked for me Aug 21 12:04:14 das: you know, 2.0.36 didnt run on anything but x86 and ppc :) Aug 21 12:04:19 yes, but also things grew more complicated Aug 21 12:04:28 true that Aug 21 12:04:41 and our toys were made of wood also Aug 21 12:04:52 my toys are still made out of wood ^^' Aug 21 12:04:58 <_troll_> are witches still made of wood? Aug 21 12:05:03 KotH: my first kernel was 2.6.3x :) Aug 21 12:05:24 das lol Aug 21 12:05:32 you missed a lot of fun Aug 21 12:05:37 I know :( Aug 21 12:05:49 I remember when 2.2 came out Aug 21 12:05:54 is this pissing contest over soon? Aug 21 12:05:57 suddenly the machine was much faster Aug 21 12:06:03 av50 no Aug 21 12:06:24 what about first kanged kernel? Aug 21 12:06:36 * ogra_ remembers 1.99 ... suddenly you could dynamically load drivers Aug 21 12:06:39 my first computer was a guy I bullied into doing my math homework Aug 21 12:06:49 which came first, the chad or the kang? Aug 21 12:07:04 das: for some reason, you look like a small kitten now :) Aug 21 12:07:11 Florida had kanging chad Aug 21 12:07:15 av500, that was you ?!? Aug 21 12:07:30 uh, chaded kernel? that doesn't sound too marketingish Aug 21 12:07:48 kanged sounds surely better Aug 21 12:07:57 av500: sorry, need to blow of some steam Aug 21 12:08:03 woglinde, stop playing with that network cable Aug 21 12:08:12 av500: people are getting in my way the whole day Aug 21 12:08:20 I might be wrong but I remember kernel 0.96 from way back Aug 21 12:08:21 ogra_: he's on mesh Aug 21 12:08:24 av500: and n00bs are the right thing for that :) Aug 21 12:08:32 not nice Aug 21 12:08:38 * KotH never said he is nice Aug 21 12:08:39 could be my first one.. I was pissed when the kernels started requiring > 4MB memory Aug 21 12:08:46 ynezz, so he shoud find thicker nodes :) Aug 21 12:08:57 Vaizki: lol Aug 21 12:08:59 been so long and too many beers, can't remember this stuff :) Aug 21 12:09:02 KotH: can you pet me ?

Aug 21 12:11:54 mru: sony? not minolta? Aug 21 12:11:58 KotH: anyway, I started playing around with unix-like on 286 and 68k before uni.. good times but the world has moved on a bit :) Aug 21 12:12:09 Vaizki: only a bit Aug 21 12:12:15 <__dumb_> thanks everyone :) Aug 21 12:12:18 KotH: sony bought minolta, not? Aug 21 12:12:22 Vaizki: the never ending september became facebook :) Aug 21 12:12:29 and I don't know if he came from minolta or not Aug 21 12:12:29 well my skills are still relevant Aug 21 12:12:34 mru: ok.. Aug 21 12:12:54 and now I have to go to a board meeting .. put some newer skills into use ;) Aug 21 12:13:13 how many layers is that board? Aug 21 12:13:21 Vaizki: being able to think, aquire knowledge and apply that knowledge are always relevant skills ;) Aug 21 12:13:41 KotH: nonsense, nowadays all you need is a youtube tutorial Aug 21 12:14:45 mru at least you do not need to ask someone to show you something over and over again Aug 21 12:15:08 yes, and it's indexed easily, one can link to relevant frame Aug 21 12:15:23 you don't need to skip nonsense, just watch it all at 4.5x Aug 21 12:15:33 how useful Aug 21 12:15:43 woglinde_: except the compiler ... if those could talk Aug 21 12:15:47 woglinde_: you mean like my coworker who asked me >5 times this morning about why he cannot send this important mail... and the answer was alway "you cannot send more than 7mb of attachments" Aug 21 12:15:47 it's useful as forum I would say Aug 21 12:16:16 that's a low limit Aug 21 12:16:19 KotH: 5x thats 35MB already Aug 21 12:16:31 av500: juup Aug 21 12:16:45 av500: and if he would continue like this, i'm sure he'll reach 100MB by the end of the day Aug 21 12:17:12 mru: the limit is 10MB usually, dont forget that attachments are base64'ed Aug 21 12:17:34 my mail server accepts much bigger Aug 21 12:17:38 *sigh* again Aug 21 12:17:39 100MB or so Aug 21 12:17:52 it's occasionally useful Aug 21 12:17:52 woglinde: poor boy Aug 21 12:18:09 mru: yes, but most external mailservers have a limit in the 10MB range Aug 21 12:18:18 who uses those? Aug 21 12:18:24 companies Aug 21 12:18:38 ah, like freescale Aug 21 12:18:43 and i want to catch too large outgoing mails soon, so people dont do anything stupid Aug 21 12:18:48 I can't send mail to freescale.com _at all_ Aug 21 12:19:10 that's because they use /dev/null as incomming filter Aug 21 12:19:11 trolllisted? Aug 21 12:19:17 no, it's freescale Aug 21 12:19:29 I get a bounce from some microsoft service saying my ip is blacklisted Aug 21 12:20:00 I wonder how big a range they block Aug 21 12:22:21 they have to finish what Cameron started Aug 21 12:25:38 mru: or they assume you are in a dynamically assigned range Aug 21 12:25:49 mru: a lot of people just block these for "security" reasons Aug 21 12:26:04 there's nothing dynamic about my range Aug 21 12:26:08 i know Aug 21 12:26:19 I even have my name in the ripe records Aug 21 12:26:36 i know Aug 21 12:26:49 but do they know? Aug 21 12:27:01 how do they decide which ranges to block? Aug 21 12:27:09 dice Aug 21 12:27:13 4 Aug 21 12:27:44 guaranteed to be random Aug 21 12:28:28 mru: you have links to open source software, they can't be dealing with your kind Aug 21 12:28:55 +1 Aug 21 12:38:45 *grml* Aug 21 12:38:48 what is it today... Aug 21 12:38:55 friday Aug 21 12:39:01 yeah.. looks like Aug 21 12:43:49 how many times must we repeat that it's _always_ friday? Aug 21 12:45:20 until its really friday Aug 21 12:46:17 mru: i whish people around me would behave like it is friday and stop bothering me Aug 21 12:46:41 maybe they didn't get the memo Aug 21 13:06:23 kinda off-topic question when i do xz -cd file.xz > /dev/mmcblk0 from where does it start to write to mmcblk0 ? Aug 21 13:06:47 vvu|Mobile: That isn't far enough off topic Aug 21 13:07:47 vvu|Mobile: The first byte of the device Aug 21 13:08:18 so it starts from the first byte....because i`m trying to dump the latest angstrom image to eMMC of the BBB and i get "short write" error Aug 21 13:09:02 ohh... I see Aug 21 13:12:14 ummm... do you try: xz -cd file.xz | dd of=/dev/mmcblk0 Aug 21 13:12:30 you can try that I mean and see if you have the same problem. *shrug* Aug 21 13:12:33 ok Aug 21 13:12:35 lemme try Aug 21 13:25:37 georgem: dd: writing '/dev/mmcblk0': No space left on device Aug 21 13:26:18 its too big then... Aug 21 13:27:01 georgem: i`m trying to get http://beagleboard.org/latest-images the 1st image Aug 21 13:27:08 to put it on the eMMC...so it`s too big Aug 21 13:27:47 the 1st image is 4GB. eMMC is 2GB Aug 21 13:28:16 oh :) Aug 21 13:28:35 yeah but 2nd one is flasher Aug 21 13:29:36 yeah. I don't see a plain image to go right on the eMMC. Seems kind of silly. Aug 21 13:32:52 I guess they just assume you wouldn't have a clue what to do with it Aug 21 13:34:22 yeah... Aug 21 13:35:25 you can probably find it somewhere. It might take some searching Aug 21 14:14:42 How to manually unload a dtbo fragment? (the reverse of echo myboard >/sys/devices/bone_capemgr.8/slots) Aug 21 14:14:50 unecho Aug 21 14:14:53 de-echo Aug 21 14:16:07 echo - Aug 21 14:16:35 echo -$foo > $bar Aug 21 14:20:04 echo - gives "bone-capemgr ...Removed slot #0", but the overlay is still in slot 7. The pins haven't changed either Aug 21 14:21:38 where is that greek when one needs him? Aug 21 14:25:39 http://pastebin.com/raw.php?i=MatD2Vyg Aug 21 14:27:37 actually http://pastebin.com/raw.php?i=3RjFEFLn Aug 21 14:31:43 av500: at the beach! Aug 21 14:32:09 looks like woglindes inet gave up at last Aug 21 14:37:26 Ever so much off topic - but I suspect you're electronics folk here. Has anyone played with those laser pointers that you can attach to your smart phone? I'm trying to figure out what sound it plays to operate the laser Aug 21 14:42:57 ? Aug 21 14:44:33 av500: sounds like french, doesn't it? Aug 21 14:46:24 narcos: plug headphone instead and listen to the sound Aug 21 14:46:32 if you are lucky, it wont zap your brain Aug 21 14:47:15 some phones multiplex a uart on the headphone jack Aug 21 14:47:23 nah Aug 21 14:47:31 I doubt that's what's being used here Aug 21 14:47:38 random $3 gadets from china dont rely on that Aug 21 14:47:47 av500: Yeah I did that, it says "bzzzzz". Trying to figure out the waveform now Aug 21 14:48:10 THis is what a scope is for. Aug 21 14:48:14 Preferably one with FFT. Aug 21 14:48:15 or golden ears Aug 21 14:49:01 or goldeneyes Aug 21 14:49:36 golden years ? Aug 21 14:49:59 golden bears Aug 21 14:50:14 Haribo! Aug 21 15:01:23 lakrizschnecken! Aug 21 15:17:04 countmail Aug 21 15:36:31 Im trying to disable the hearbeat led using a dtbo. I can compile and install ok but led is still flashing the heartbeat. Here is my overlay. http://pastebin.com/raw.php?i=50tLtKy3 Aug 21 15:37:18 monzie: just curious why you are trying to do it with a dtbo? Aug 21 15:37:28 monzie: why not just turn it off? Aug 21 15:37:43 Just trying to learn for now Aug 21 15:38:16 Trying to understand dtbos better Aug 21 15:43:13 monzie: ahh well that example is probably not the best to use, as the configuration is loaded by default with the kernel image, and would require other measures to work properly Aug 21 15:44:28 * LetoThe2nd welcomes the palgue Aug 21 15:44:31 plague, even Aug 21 15:47:21 LetoThe2nd: greetings old friend Aug 21 15:47:39 LetoThe2nd: i trust buried life isn't treating you badly, hehe Aug 21 15:47:47 s/buried/married Aug 21 15:48:32 prpplague: life's going pretty well here besides having to tinker some historic code with the worlds most fucked up compiler (IAR) at work ;) Aug 21 15:48:42 prpplague: dont worry, those two words mean the same thing ;) Aug 21 15:48:42 hehe Aug 21 15:48:49 * LetoThe2nd hopes the same or better for you Aug 21 15:48:58 KotH: i know that, but LetoThe2nd is just now finding that out.... Aug 21 15:49:07 hehehe Aug 21 15:49:09 LetoThe2nd: that's not nice, hoping someone has to work with iar Aug 21 15:49:25 KotH: "or better" Aug 21 15:49:33 only better Aug 21 15:49:40 iar is worse than the plague! Aug 21 15:49:44 prpplague: no offence ;) Aug 21 15:50:15 prpplague: What other measures are required? Aug 21 15:51:09 imperial measures Aug 21 15:51:24 drastic measures Aug 21 15:52:11 Changing the interrupt type should be trivial, something an overlay can handle , right? Aug 21 15:52:39 * das wonders if there's a clean way to integrate circles into squares Aug 21 15:53:29 das: well just take care that neither gets dirty before integration. Aug 21 15:53:49 LetoThe2nd: believe it or not, there compilers worse than iar Aug 21 15:53:58 unicorns much ? Aug 21 15:54:01 mru: i do not believe. Aug 21 15:54:44 I've seen alleged c compilers that couldn't handle statements like a = b = 0; Aug 21 15:54:53 monzie: you would need to edit the am335x-bone-common.dtsi and recompile the kernel Aug 21 15:55:33 mru: adhering to the c standard is option, or what? Aug 21 15:56:46 it also did strange things if you passed a va_list as argument to a function Aug 21 15:56:51 so no calling vprintf Aug 21 15:59:04 pprplague: ok thanks. Aug 21 15:59:45 Isn Aug 21 16:00:04 Isn't avoiding recompiling the kernel the whole reason the device tree exists? Aug 21 16:01:04 no Aug 21 16:01:36 <_av500_> its to reduce churn Aug 21 16:02:32 it's to make embedded development more difficult, so we can get better salary Aug 21 16:03:06 KotH: I think that's it! Aug 21 16:03:29 So if I want to release a cape that uses the hearbeat led for another purpose I have to release a custom kernel? doesn't seem right to me. Aug 21 16:03:33 <_av500_> not difficult, just different Aug 21 16:03:35 KotH: exactly Aug 21 16:03:45 <_av500_> monzie: ? Aug 21 16:05:04 What my current understanding is that to modify the "hearbeat" led functionality I have to recompile the kernel. Aug 21 16:05:13 <_av500_> no Aug 21 16:05:20 <_av500_> its set by a led trigger Aug 21 16:05:24 <_av500_> from sysfs or so Aug 21 16:05:31 That is what pprplague said Aug 21 16:05:47 I am trying to do it with an overlay Aug 21 16:07:07 _av500: here is my overlay file http://pastebin.com/raw.php?i=50tLtKy3 Aug 21 16:07:21 After I apply it the heartbeat led keeps beating. Aug 21 16:31:47 Natata Aug 21 16:32:03 that's spelled hakuna matata Aug 21 16:33:50 moooo Aug 21 16:33:57 mooo hooo Aug 21 16:34:02 I could use some Pastéis de Nata right now Aug 21 16:34:02 morning :) Aug 21 17:02:51 feels like 12 year-olds are writing makefiles here Aug 21 17:02:56 "[ 0%] Build, wait a moment plz ..." Aug 21 17:04:16 nuke them from orbit Aug 21 17:04:20 only way to be sure Aug 21 17:04:23 is that with waf or something? Aug 21 17:04:46 man waf Aug 21 17:05:17 Cmake? Aug 21 17:05:32 yeah, I was gonna say that either looks like cmake or waf Aug 21 17:06:09 yep cmake Aug 21 17:06:28 did some autotools this morning, I now praise cmake Aug 21 17:06:37 * panto hates cake Aug 21 17:06:46 Err damn autocomplete Aug 21 17:06:48 lD Aug 21 17:06:51 Cmake Aug 21 17:06:59 I hate cmake. waf is... interesting I haven't decided if I like it yet Aug 21 17:10:51 autotools has it's issues too. configure doesn't run checks in parallel so its slow. It also needs a lint or something to keep people from doing stupid shit with it Aug 21 17:11:30 georgem: At least it cross compiles properly Aug 21 17:12:08 it's just so complicated Aug 21 17:12:50 panto: not entirely http://lists.gnu.org/archive/html/autoconf/2012-10/msg00084.html Aug 21 17:12:50 So is cmake Aug 21 17:13:12 cmake is bad too, just not as Aug 21 17:13:53 (well, I think they're bad just because I spend too much time figuring out what's happening, maybe experts have a different opinion) Aug 21 17:14:30 das: waf? Aug 21 17:15:00 georgem: never heard of it until you mentioned it a couple minutes earlier Aug 21 17:15:06 ah ok Aug 21 17:15:25 samba related stuff uses it Aug 21 17:15:27 I don't think it's the kind of thing you see a lot in the 'work world' ? Aug 21 17:17:21 god that integration is going nowhere and my boss is on holidays ... Aug 21 17:17:36 damn Intel ! Aug 21 17:18:00 das make a party at work Aug 21 17:18:17 I asked who wanted to play quake3 at lunch Aug 21 17:18:23 noone knows what it is :( Aug 21 17:18:23 lol Aug 21 17:18:32 double lol Aug 21 17:18:35 they don't know xkcd either :( Aug 21 17:18:42 georgem you can not stop people doing shitty thinks with your stuff Aug 21 17:18:44 ok that one stumped me Aug 21 17:18:56 quake3 is lame Aug 21 17:19:02 play dayz origins Aug 21 17:19:04 Q3 is old. Aug 21 17:19:10 I have to go out of my way to goof off quite often while I wait for people to get their shit finished Aug 21 17:19:17 also they all have gfs Aug 21 17:19:29 das get one too or buy one Aug 21 17:19:31 das, those evil womanizers . . . Aug 21 17:19:33 from russia or asia Aug 21 17:19:44 my wife plays games with me Aug 21 17:19:55 like dayz Aug 21 17:19:58 georgem hehe lucky Aug 21 17:19:58 georgem: TMI. Aug 21 17:20:34 woglinde: I'm not sure how to do either Aug 21 17:20:42 das ????? Aug 21 17:21:01 I found my wife via chatting Aug 21 17:21:04 so do the same Aug 21 17:21:10 same Aug 21 17:21:12 I went to a bar and asked a girl if my tissue smelled like chloroform to her, but she didn't fall for it Aug 21 17:21:32 Good muscle memory. Aug 21 17:21:57 das in bars you do not find woman for life Aug 21 17:22:05 only for one night Aug 21 17:22:17 ? Aug 21 17:22:36 once they're chained in your basement, if you bring enough food and water they should last longer than one night Aug 21 17:22:41 I think Aug 21 17:22:45 lmao Aug 21 17:23:38 das I see see Aug 21 17:23:43 go on play quake3 Aug 21 17:24:10 I started playing Avadon: The Black Fortress Aug 21 17:25:06 anyways; rum o'clock ! Aug 21 17:26:10 georgem looks a bit like ultima Aug 21 17:26:29 woglinde: yeah. looks a bit like it. plays a bit differently though Aug 21 17:27:15 but I never really played ultima *g* Aug 21 17:29:13 hm should I buy a jolla phone Aug 21 17:31:34 crappy dsl line again Aug 21 17:34:23 buy a jolla phone if you have the money and want to support them and tinker with it. otherwise wait until they've been out for a while and good reviews come in Aug 21 17:35:51 lol Aug 21 17:36:17 that was rhetoric Aug 21 17:54:00 <_SY_> hello Aug 21 18:31:56 <_av500_> woglinde_: maybe you can run ubuntu phone on it? Aug 21 18:35:32 av500 no it has no android driver Aug 21 18:44:10 <_av500_> damn Aug 21 18:44:13 <_av500_> maybe FFos? Aug 21 18:46:04 damn dsl line Aug 21 18:48:02 woglinde_: high quality alice DSL, I know the pain Aug 21 18:48:11 I see opkg upgrade still does the nasty.... Aug 21 18:48:26 kblin: works fine in my city.. Aug 21 18:49:13 Humpelstilzchen: arguably, alice can't really be blamed on the state of DSL in this village, it's the same lousy line for all providers Aug 21 18:51:54 djlewis: what is it doing? Aug 21 19:02:53 kblin it is not alice fault its really the line Aug 21 19:04:39 woglinde: yeah, same here Aug 21 19:22:05 mru: i just checked the sd card specs, there is, protocol wise, no difference between sdhc and sdxc for read/write Aug 21 19:22:41 mru: and read/write use 32bit for block address 2TB can be addressed Aug 21 19:22:56 where's the difference? clock rates? Aug 21 19:23:47 istr sdxc allowing higher clocks Aug 21 19:23:51 dunno.. havent checked for the details Aug 21 19:24:26 but probably it's just additional capabilities Aug 21 19:27:40 How many write cycles can the BBB on board flash handle? Aug 21 19:28:05 look up the chips datasheet Aug 21 19:28:16 prolly in the range of 10k Aug 21 19:29:44 blaaa: you mean how many cycles of writing the entire capacity? Aug 21 19:30:44 georgem: the number of cycles are defined by block. as writing the flash is done over the same block with no wear leveling, the number of writing the full capacity does not matter Aug 21 19:31:07 you can't use that chip without wear leveling Aug 21 19:31:12 its built in Aug 21 19:31:30 hmm? Aug 21 19:31:42 it's not just a flash at a fancy interface? Aug 21 19:32:14 I'm on a phone right now, hard to get hold of data sheets, but I'll look it up Aug 21 19:32:29 KotH: http://www.micron.com/products/managed-nand/e-mmc Aug 21 19:32:39 <_av500_> KotH: emmc is SD/MMC Aug 21 19:32:49 <_av500_> the specs you are reading :) Aug 21 19:33:04 oh! shiny! Aug 21 19:33:42 ah, fancy Aug 21 19:33:49 suspected it had something like that but now I know for sure :) Aug 21 19:33:50 as long as you don't loose power while the wear leveling is moving your file system super block Aug 21 19:34:51 well, the card should handle even that Aug 21 19:35:01 compared to wear leveling, superblock moves are easy :) Aug 21 19:36:21 n'abend woglinde_ Aug 21 19:36:28 the price for these things is even reasonable! Aug 21 19:36:46 price for what? Aug 21 19:37:09 <_av500_> beer Aug 21 19:37:12 for the emmc modules Aug 21 19:37:21 _av500_: s/beer/chocolate/ Aug 21 19:37:26 the price is reasonable but the availability is terrible Aug 21 19:37:29 _av500_: i'm not mranostay Aug 21 19:37:37 expect huge lead times Aug 21 19:37:59 unless you're a smart phone manufacturer Aug 21 19:38:09 georgem: i've dealt with 26 weeks on capacitors, i've seen >50 weeks for parts. those are definitly not going to shock me :) Aug 21 19:38:19 holy crap! Aug 21 19:38:28 Is there anywhere you can buy them in ones? Aug 21 19:38:33 no Aug 21 19:38:37 I've idly wondered about upgrading phones and stuff Aug 21 19:38:40 SpeedEvil: findchip doesnt know any Aug 21 19:38:53 I'll have some in a few days Aug 21 19:39:01 maybe one could into the mail... Aug 21 19:39:03 SpeedEvil: but you can try ebv, msc-gleichmann & co whether they can get you some Aug 21 19:39:08 could find its way* Aug 21 19:39:17 KotH: Singificantly easier to fin dthan the other memory I was looking for - POP RAM to upgrade my phone Aug 21 19:39:18 wonder how long it took circuitco? Aug 21 19:39:35 * SpeedEvil wants the only N900 with 512M Aug 21 19:39:40 And 700MHz processor Aug 21 19:39:54 SpeedEvil: alternatively you can buy sdcard controllers from hyperstone and a supported nandflash Aug 21 19:40:15 KotH: Naah - RAM, not flash Aug 21 19:40:19 SpeedEvil: and hyperstone has a minimum sales of 50 Aug 21 19:40:22 Oh - right - for EMMC Aug 21 19:40:40 I suspect you can probably convince most stuff wanting EMMC to use SD Aug 21 19:40:50 Though I may be optimistic Aug 21 19:40:51 and you can get complete diced wavers nearly for free :) Aug 21 19:40:52 its 8 bit Aug 21 19:40:54 not 4 Aug 21 19:41:03 SpeedEvil: bigger keys.. Aug 21 19:41:25 And I know Aug 21 19:41:29 heh unrelated (slightly) topic, does anyone have insight into how distributors like Mouser decide which packages of a chip to carry in single-qty-sellable formats vs. those that are like "non-stocked, you can buy 200+ from us if you want"? Aug 21 19:41:47 is it related to which package big customers of theirs are asking for, I wonder Aug 21 19:41:49 Spirilis: those that sell single quantity Aug 21 19:42:33 Spirilis: They probably only sell stuff in single quantities that they already have in their warehouse. Aug 21 19:43:03 georgem: nah.. that way they wouldnt get any new parts :) Aug 21 19:43:10 georgem: ah k, so the "spark" that starts such a stock is probably someone making a commitment to buy them in higher quantities? Aug 21 19:43:36 i guess they have someone who desides based on experience which new parts are worthy to be stocked and sold single quantity Aug 21 19:43:41 the chip in question is the MSP430 G2955, you can buy the RHA package (QFN) in single qty but not the DA (0.65mm-pitch TSSOP, i.e. solderable by us MERE MORTALS!) package Aug 21 19:43:55 lol Aug 21 19:43:56 QFN is doable Aug 21 19:44:06 i wouldnt call TSSOP solderable by mere mortals Aug 21 19:44:12 * SpeedEvil wonders if he can remember the link to 'how to solder by hand' Aug 21 19:44:16 you need good equipment and a steady hand for that kind of stuff Aug 21 19:44:40 well, I've done a lot of TSSOP's in that same package... I built my own F5172 "launchpad" and sold a number through 43oh.com so I'm familiar with it. It's pretty easy for me. Aug 21 19:44:41 or you need mrpackethead style equipment Aug 21 19:44:42 yeah Aug 21 19:44:51 Basically - build up the pad in the middle with a solderblob Aug 21 19:44:55 I suspect if they have multiple customers ordering large quantities of a part they're making an even larger buy from the manufacturer and they probably sell off the excess in single quantities Aug 21 19:44:57 then reflow it with IR Aug 21 19:45:07 Then use a tiny tip and solder Aug 21 19:45:17 yeah, maybe I'll have to try QFN at some point. I do have a reflow skillet now and solder paste. Aug 21 19:45:21 georgem: anyone doing large quantities will not buy from mouser Aug 21 19:45:25 just been skittish about coming anywhere near it Aug 21 19:45:45 georgem: the big distributors are a lot cheaper if you go >100 on most parts Aug 21 19:45:46 KotH: that's also what I was thinking Aug 21 19:45:46 http://www.youtube.com/watch?v=c_Qt5CtUlqY Aug 21 19:45:48 georgem: and if you go 10k, you buy directly from the manufacturer Aug 21 19:45:56 who are these "big customers" using mouser and what qty are they commanding Aug 21 19:46:11 its all relative Aug 21 19:46:14 I may just send an email to mouser asking this question, guess I should... Aug 21 19:46:26 - how to solder a QFN with soldering iron Aug 21 19:46:44 SpeedEvil: works only with Pb solder Aug 21 19:46:59 SpeedEvil: and only if the pads are going right to the edge Aug 21 19:47:10 No Aug 21 19:47:17 With SAC - see above Aug 21 19:47:23 SAC? Aug 21 19:47:38 Soldering... I shiver when I think about my electric guitar, let alone small parts... Aug 21 19:47:41 the other thing that amuses me is Mouser carries some of the Tiva-C (ARM Cortex-M4F) chips in single qty, a lot of them in fact. their "stock" isn't terribly high from what I recall, so I wonder if that was a special deal with TI to try and "get the chips out there" Aug 21 19:47:43 ah.. hot air gun Aug 21 19:48:12 yeah.. hot air gun works, but taht needs even more experience :) Aug 21 19:48:43 Spirilis: probably got just a single reel of each and are now waiting to finish them Aug 21 19:48:43 <_av500_> SpeedEvil: N900 is omap3, no? Aug 21 19:48:51 <_av500_> thus the memory is POP NAND, no? Aug 21 19:48:52 yes Aug 21 19:48:55 yes Aug 21 19:48:59 Spirilis: depending on whether they sell well enough they will either get a new real, or put it as non-stock Aug 21 19:49:03 Well - it has POP and emmc Aug 21 19:49:08 <_av500_> ah Aug 21 19:49:20 KotH: yeah I can imagine that. Now they should do it with the MSP430G2955IDA38R :) Aug 21 19:49:33 Spirilis: write them a mail Aug 21 19:49:38 I think that in principle there is a 1G RAM part - which would work - but ... Aug 21 19:49:49 It can also boot from the MMC Aug 21 19:50:52 SpeedEvil: wait a sec, you want to change a POP RAM module? Aug 21 19:50:57 yes Aug 21 19:51:16 Though I want to change the processor at the same time Aug 21 19:51:17 oh...kay....what kind of god like equipment do you have at home? Aug 21 19:51:45 Just IR/hot air. Aug 21 19:52:10 well..ok, then you have to change both at the same time :) Aug 21 19:52:12 Also - it's kind of irrelevant as the part is not available Aug 21 19:52:16 hi Aug 21 19:52:31 * KotH ignites preplasma Aug 21 19:52:34 I question have to. It's probably going to be a lot easier Aug 21 19:52:46 SpeedEvil: have you ever soldered bga? Aug 21 19:52:50 yes Aug 21 19:52:57 or rather, have you ever unsoldered bga? Aug 21 19:53:21 and again yes - and I'm aware of the issues. Aug 21 19:53:32 It becomes a lot easier when it's a purely theoretical problem Aug 21 19:53:43 *g* Aug 21 19:53:55 * SpeedEvil needs to get his laser solderer working Aug 21 19:54:21 SpeedEvil: ooh, didn't realize they had "mini SMT stencils" to attack the problem. Aug 21 19:54:26 SpeedEvil: just saw that in your youtube link Aug 21 19:54:44 that was my main aversion to trying it with my reflow skillet, getting the solder paste down Aug 21 19:54:46 Spirilis: That's not the approach I was thinking of. Aug 21 19:54:56 what is the best keyboard and mouse for the bbb ? usb other a hub or a wireless keyboard mouse bundle ? Aug 21 19:55:17 Spirilis: The initial one was to level the pad with some solder - reflow with hot air - then use long pads sticking out from under the chip to reflow onto Aug 21 19:55:30 the solder bump rises, contacts the chip, and reflows. Aug 21 19:55:49 SpeedEvil: yeah, I see a couple approaches in there. I suspect using a mini stencil would be my optimal method since I don't have hot air Aug 21 19:56:01 Hot air is cheap Aug 21 19:56:21 Spirilis: when you buy a pcb, you can get a stencil with it nearly for free. olimex, eurocircuits and others sell stencil sets Aug 21 19:56:53 http://www.youtube.com/watch?v=pdGSFc7VjBE - also Aug 21 19:56:59 only thing you need then is paste :) Aug 21 19:57:07 yeah paste I have (Pb-based, even) Aug 21 19:57:08 Vendors without stencils can be rather cheaper though Aug 21 19:57:24 Mikeselectricstuff - quick hints on quick SMT assembly Aug 21 19:57:30 is a normal usb keyboard and a normal usb mouse ok for the bbb ? do i need a aktive hub ? Aug 21 19:57:43 and I often either use oshpark or the cheap chinese guys (elecrow, seeed), I think they have stencils but the cost isn't nearly as trivial as their low-run small boards are Aug 21 19:57:59 er oshpark doesn't, but elecrow or seeed I think offer stencils Aug 21 19:58:57 preplasma: yes, a normal usb keyboard is fine Aug 21 19:59:24 hmm Aug 21 19:59:48 ok thx Aug 21 19:59:54 cu Aug 21 20:01:12 ah i use my oven to reflow @home Aug 21 20:02:12 this is how it's done: http://hardwarebug.org/files/beagle_toaster.jpg Aug 21 20:02:35 haha nice Aug 21 20:03:21 this is less good: http://hardwarebug.org/files/beagle_fried.jpg Aug 21 20:05:51 haha no ! Aug 21 20:09:20 the latter is how I roll, albeit electric skillet with thermocouple sticking through the steam hole of the cover & triac switching the power Aug 21 20:12:37 I have BBB that doesn't light any led when it's connected to power, be it USB or 5V DC. Aug 21 20:13:06 Tried booting from SD or from eMMC. Nothing. Aug 21 20:13:28 The power seems OK, as this board worked. Also I have another BBB that behaves correctly. Aug 21 20:13:42 Advice? Aug 21 20:14:16 no LEDs turn on at all, including the power LED? Aug 21 20:15:03 Does nog sound ok Aug 21 20:15:14 Power LED lit. Aug 21 20:15:31 Ethernet LEDS blink Aug 21 20:15:50 k, got an FTDI cable or suitable breakout board to watch the serial debug console? Aug 21 20:15:50 Try to boot from some microsd Aug 21 20:16:01 Or best the serial of course Aug 21 20:16:03 tried it. Aug 21 20:16:10 tried the SD, that is. Aug 21 20:16:30 Don't have FTDI. Aug 21 20:17:13 yeah I generally think that beyond the most trivial issues, an FTDI is necessary to do work with these boards. only really need 1 that you can move between them. Do you have any other form of ttl/cmos-level UARTs? even an Arduino? Aug 21 20:18:26 As a matter of fact, I do have some other boards. Some eclectic collection of STM discovery, arduino mega and PSOC 4. Aug 21 20:18:45 From seminars and things. Aug 21 20:19:24 k, the arduino mega might work. Write a sketch to it that does nothing, makes sure the RX & TX pins are set to Input mode so they don't load the lines, then run jumper wires from the primary RX & TX pins over to the TX & RX pins in the BBB's 6-pin header. Connect a similar jumper wire between the GND's. Aug 21 20:19:52 open up the arduino mega's UART with a terminal app of some type, set it to 115200/8/N/1 and plug in the BBB's power Aug 21 20:20:53 er, let me verify which TX/RX pin goes where first. Aug 21 20:21:05 I think it's TX from the arduino goes to TX on the bbb's 6-pin header, similar for RX Aug 21 20:21:21 Don't I need to write a sketch to bridge between the UARTs? Aug 21 20:21:35 Nah, write a sketch that tells the mega to stay hands-off Aug 21 20:21:56 Then you're basically tieing the BBB into the mega's uart bridge that goes between the USB cable for the mega and the mega itself Aug 21 20:22:04 hijacking it for nefarious external use Aug 21 20:23:52 I believe I got it. Aug 21 20:24:26 I'll need to get some jumper wires... Aug 21 20:24:58 proper ones, that it. Aug 21 20:24:58 yeah, if you have a 1x6 female header (or can cut one from a larger 1x36 or 1x40 or whatever) it might be cool to have a dedicated header + wires for this so it's handy later on Aug 21 20:25:10 soldering the wires to the pins of the female header Aug 21 20:25:29 ...but that's if you're serious about not buying an FTDI cable :) Aug 21 20:26:23 I have some USB2UART with FTDI, RS232, RS485 at work. I'll use that. But for FTDI it still required proper jumpers. Aug 21 20:26:46 I'll need to get myself a decent jumper kit with all kinds of genders and lengths. No escaping that. Aug 21 20:26:52 From what I know, this works with the bbb's FTDI 6-pin header, but don't try connecting the arduino mega's UART pins to the other UART pins in the P9/P8 expansion headers since they can only tolerate 3.3V maximum Aug 21 20:26:58 https://lh4.googleusercontent.com/-3oca40vrH-g/Ubd5TjD-0_I/AAAAAAAAALU/-GibZBaTvKk/s1024/beaglebone-black-serial.jpg Aug 21 20:27:06 for the visually unimpared ;) Aug 21 20:27:13 hi Spirilis Aug 21 20:27:17 sup m_billybob Aug 21 20:27:22 not a whole lot Aug 21 20:27:31 how you ben ? Aug 21 20:27:42 HVAC mess cleaned up ? Aug 21 20:27:44 alright I guess, still no workbench downstairs, getting close to bringing it all back Aug 21 20:27:51 :/ Aug 21 20:27:54 pretty much, insulating the ducts now Aug 21 20:28:19 had drywall work done and it looks good, reorganized the garage, need to get an electrician in to do a proper code-approved expansion of the circuits in the basement though Aug 21 20:28:34 (would do it myself but I can't pull permits here, and they are required if I ever plan to sell the house) Aug 21 20:28:59 or just have the electrcian verfy your work ? dont know if you're ok with house electrical . . . Aug 21 20:29:10 most ee's are Aug 21 20:29:42 I think and this may be locale specific you can do all the work and pay an electrician to come in an inspect your work Aug 21 20:30:08 * KotH is allowed to do his home electrics himself Aug 21 20:30:16 having an EE degree helps :) Aug 21 20:30:17 yeah the permit process is what I'm confused about though, I think they send a county inspector to verify it but not sure if that's just written in the law and never enforced or what Aug 21 20:30:32 right thats why you pay the electrcian Aug 21 20:30:41 Spirilis: it's a insurance thing Aug 21 20:30:58 ah yeah, probably Aug 21 20:31:00 he inspects, paus off his county inspector buddy or whatever . . .copasetic ;) Aug 21 20:31:06 well at that rate I might as well have the dude come in anyway Aug 21 20:31:08 or yeah not really but you know what i mean Aug 21 20:31:13 less crap on my plate to worry about Aug 21 20:31:25 * m_billybob nods Aug 21 20:32:13 its all good. personally i dont like effign arodn with hvac Aug 21 20:32:43 id wire up boxes when i worked on cell phone sites, but wouldnt get near them after power was applied Aug 21 20:32:52 it's not too complicated, adding circuits to support the dehumidifiers and a ceiling fan/light fixture in the downstairs living room, but what I'm not sure about is getting the wires over to the locations & what is "code approved" in terms of different techniques for routing them Aug 21 20:33:21 and what they can accomplish without ripping out the wall boards in the rooms Aug 21 20:33:47 hard to describe but basically there's a stairwell in the middle of it all, so routing stuff around that is what I'm not sure about Aug 21 20:34:02 * m_billybob nods Aug 21 20:34:09 so I figure someone with more experience would have a better idea about that Aug 21 20:34:45 you possibly make more an hour at work anyhow so yeah pay a fraction of the ole paycheck so you dont have to deal with it ;) Aug 21 20:34:52 yeah Aug 21 20:35:37 err that pic i pasted a link earlier was for you and that person you were talkign to Aug 21 20:35:51 makes it pretty plain, just like how i like it Aug 21 20:36:17 same one i put up on beaglefu Aug 21 20:36:46 basically stole the pic of the bbb form somone else shopped it bam done Aug 21 20:37:39 hey guys! Anyome know how to add usb gadget to a base beaglebone Yocto build? Aug 21 20:38:30 define usb gadget Aug 21 20:39:55 Spirilis OMG lmao i almost nearly fell out of my chair Aug 21 20:39:58 https://www.sparkfun.com/products/retired/10622 Aug 21 20:40:33 I think the recipe is called gadget-init .. it is meant to add ethernet over usb device "gadget" and mass storage like the Angstome build Aug 21 20:41:03 brm ok to the USB g_ether / g_multi driver module im assuming Aug 21 20:41:15 so the* Aug 21 20:42:00 when I add the gadget-init recepe boot complains of missing g_ther Aug 21 20:42:17 install the kernel module? Aug 21 20:42:33 brm ok, ill have to defer to someone else who knows Yockto Aug 21 20:42:35 opkg update Aug 21 20:42:39 how do I do that auto on boot? Aug 21 20:42:41 opkg list | grep g_ether Aug 21 20:42:55 opkg install kernel-module-foo-g_ether Aug 21 20:43:32 aussuming you have a working connection on the board Aug 21 20:43:34 besides usb Aug 21 20:43:39 I don't want to use the package management .. want to build it in Aug 21 20:43:49 otherwise use sdcard or usbstick Aug 21 20:43:53 to copy stuff over Aug 21 20:44:06 than change the kernel config Aug 21 20:44:14 yocto docu will tell you how Aug 21 20:44:47 gn Aug 21 20:45:07 so .. I am configuring the kernel to include that module .. right? Aug 21 20:45:09 hey guys im somewhat of a noob with the beaglebone, and for whatever reason at set up on my mac the beaglebone start page does not recognize my installed drivers :( Aug 21 20:47:20 * m_billybob isnt good with MAC's Aug 21 20:47:22 sprry Aug 21 20:47:25 sorry too Aug 21 20:47:31 ah i see Aug 21 20:47:35 well thanks anyway Aug 21 20:47:37 someone else may know Aug 21 20:48:17 lagrz you may try looking on the groups ( beagleboard google groups ) i know theres been posts on there about the same thing Aug 21 20:48:26 you'd ideally want to search first of course Aug 21 20:48:30 will do so thanks Aug 21 21:05:14 is it a pretty common issue where a beaglebone board comes with missing '/var/lib/cloud9' folder? Aug 21 21:19:21 lagrz personally. I could not say. I dont run Angstrom on my own BBB's Aug 21 22:51:13 so: I'm trying to boot a BeagleBoneBlack using nfsroot, and I'm getting this exact error condition: http://pastebin.com/SxycpshX Aug 21 22:51:35 and I found an IRC log of a guy asking about it in here Aug 21 22:51:51 I just wanted to know if anyone had figured that out Aug 21 22:52:19 (the pastebin log isn't from me, it's from the dude who asked about the problem before) Aug 21 22:52:40 I tried the fixes people mentioned in the IRC chatlog here: http://logs.nslu2-linux.org/livelogs/beagle/beagle.20130309.txt Aug 21 22:52:42 with no luck Aug 21 22:59:00 Hi, how to check which version of BeableBoard/Armstrong is flashed to my bbb ? Aug 21 23:00:10 /etc/issue has record stating "Angstrom v2012.12" - is this the latest version ? Aug 21 23:07:20 That looks like that would be the version you have installed. Aug 21 23:07:32 Did you try checking the webstie to see if there was a newer version? Aug 21 23:49:32 Has *anyone* gotten angstrom-v2013.06-yocto1.4 to build recently for the bbb? Aug 22 00:35:26 hi Aug 22 00:36:05 hi boys, girls, trolls, and mranostay Aug 22 00:44:23 mru: why the hate? Aug 22 01:08:57 mranostay, pingu? Aug 22 02:19:40 hey, how can i add a message to the system log? Aug 22 02:19:52 bbb, latest image Aug 22 02:19:54 the syslog command doesn't seem to exist. Aug 22 02:20:18 nomel: is logger not installed? Aug 22 02:20:53 it is! juts didn't know what i was looking for. Aug 22 02:20:54 thanks yo. Aug 22 02:21:03 nomel: no problem at all :) Aug 22 02:21:13 * nomel puts on his latex glove and gives wolfeidau a high five. Aug 22 02:38:28 is there any sort of working solution for storing the device tree for a cape in the eeprom Aug 22 02:38:33 ? Aug 22 02:57:26 *hassle*. . . Someone's always got my nick. Aug 22 02:58:03 hey folks! any news on the 8/20 production image? (was going to post today?) **** ENDING LOGGING AT Thu Aug 22 02:59:58 2013
