**** BEGIN LOGGING AT Tue Sep 10 03:00:00 2013 Sep 10 03:00:55 hi, there. After I perform opkg update and upgrade. reboot, I can't see a mount usb driver on my win7 Sep 10 03:04:07 I connection my board to a monitor and using a keyboard I can login, it seem to work fine Sep 10 03:05:44 I think there is something wrong with usb connection when I perform the opkg upgrade, but I can' t figure out what happened after google. any suggestion would be greatly appreciated! Sep 10 03:07:18 I received yesterday my BEAGLEBONE black but I can not install gnumeric. Is it possible? Sep 10 03:38:58 does the emmc-flasher image include a desktop? Sep 10 04:13:55 daniel_ohh: what's Gnome? Sep 10 04:15:56 sky_: do you have the latest production image shown on the wiki? Sep 10 04:16:29 sky_: opkg upgrade has a long history of breaking things, especially with older images. no idea if it breaks the current one. general word in here has always been "don't opkg upgrade" :-| Sep 10 05:05:05 i have downloaded toolchain for beaglebone and i wrote a sample program test.c in ubundtu....how to cross compile this test.c.....which command should be used... Sep 10 05:06:48 i have downloaded toolchain for beaglebone and i wrote a sample program test.c in ubundtu....how to cross compile this test.c.....which command should be used.. Sep 10 05:07:37 can someone say the command to crosscompile... Sep 10 05:18:06 Quick question for anyone that is willing to help... Does the Beagleboard-xM support the LCD4 + TiWi-5E capes while running Android? Sep 10 06:00:45 wated to run the qt4 on target (beaglboard-xM) which online package should I run from angstrom ? because I got embedded and x11 both of them in thr on additional development tool Sep 10 06:06:21 \ Sep 10 06:21:25 so, i notice this sysfs led interface is somewhat useless if multiple processes are trying to do things with the leds Sep 10 06:22:03 so, i think i'm going to make a multi process type message based led control Sep 10 06:22:21 huh, you're wondering that controlling a single digital output device by multiple processes does not work? Sep 10 06:22:47 no, i'm noticing the sysfs interface sucks for it, because the interface changes depending on what the led is doing. Sep 10 06:25:13 you can write a proper LED trigger Sep 10 06:25:38 yeah. that's what i want to do. :P Sep 10 06:27:40 i'll probably stick with the sysfs since blinking and kernel level stuff like cpu and disk wouldn't be so great if they were controlled by some daemon Sep 10 06:32:49 nomel, the sysfs interface works fine for changing state from many different processes...its just whichever one was last wins Sep 10 06:34:28 or whichever touches "trigger" last wins. :) Sep 10 06:35:05 the situation I'm thinking you might be in would be if the led needs to be lit if a counter is greater than 0, or if an even has happened in the past 500ms Sep 10 06:35:12 er, event Sep 10 06:35:18 trolls Sep 10 06:35:24 i'll probably do a posix_ipc or some other message based thing Sep 10 06:35:33 then you could have priorities and whatnot Sep 10 06:35:44 nomel : I wanted to run the executable file of qt4 on my target I hv copied the file using ethernet but when i am going for execute tht file it is giving me "sh: ./Test :not found " Sep 10 06:35:56 message might say something like "blink at some rate for 100ms, priority 2" Sep 10 06:36:13 ah, like a status bar stack Sep 10 06:36:30 some activity led might have a lower priority, so it would get ignored and flushed. Sep 10 06:36:34 yeah. Sep 10 06:36:59 hrmm...i should search for something that exists. Sep 10 06:39:16 helllo Sep 10 06:40:36 nilking: i have no idea what you're saying, but i'm assuming that the file Test doesn't exist in your current directory. Sep 10 06:40:48 or maybe Test is a directory. Sep 10 06:41:23 more likely a library it links to wasn't found Sep 10 06:41:23 xyz, please direct pleasantries to mrpackethead. Sep 10 06:41:47 i have beaglebone black with me...Now i wanted to write a program for that...so i downloaded a crosscompiler for ubuntu,which i am using......so now i have my sample code test.c and the cross compliler......what command should be used to cross compile... Sep 10 06:42:29 dude, there's like a million and one cross compile on beaglebone examples out there. Sep 10 06:43:00 nomel...can you please give a link Sep 10 06:43:43 moaning Sep 10 06:45:14 xyz: google "setup cross compiler for beaglebone", i see plenty. Sep 10 06:45:35 i *could* have lmgtfy'd that, *but i was feeling nice*. Sep 10 06:47:23 * nomel throws a chair at the wall. Sep 10 06:49:48 nomel: do u have any idea about the remote debugging using angstrom ? Sep 10 06:50:23 if yes then on my target i have copied this Test file while it is not running. Sep 10 06:54:26 nilking: sorry, no. :-\ Sep 10 06:57:20 JIHADli Sep 10 07:26:58 KotH: i was thiking its too warly Sep 10 07:27:00 early Sep 10 07:27:01 for you Sep 10 07:39:47 mrpackethead: The KotH strikes in the night, when you least expect it. Sep 10 07:40:21 KotH: just eats chocolate Sep 10 07:46:46 https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-ash4/1268731_10151858833832661_467444346_o.jpg Sep 10 07:46:49 todays ebay purchase Sep 10 07:46:51 :-) Sep 10 07:48:00 looks nice Sep 10 07:48:16 does it have a ring light or something ? Sep 10 07:49:03 how much was it? Sep 10 07:49:29 http://www.ebay.com/itm/Vision-Engineering-Mantis-Microscope-4x-6x-/330969090638 ?!? Sep 10 07:51:23 wow. Sep 10 07:52:02 I got this for $1k Sep 10 07:52:16 pretty good Sep 10 07:52:17 we grabbed two much nicer from a failed startup for $200. :-| Sep 10 07:52:28 of course you did nomel. Sep 10 07:52:34 you do everythign better than everyone Sep 10 07:52:44 wasn't me, it was my last company. Sep 10 07:52:49 planning on reverse engineering some chips ? Sep 10 07:52:52 err..the last company i worked for. Sep 10 07:53:20 mrpackethead: and wtf, you wanna FIGHT? Sep 10 07:53:34 nomel: i dont' fight girls Sep 10 07:53:59 good, this will be easy then Sep 10 07:54:18 * nomel gently slaps mrpackethead AS HARD AS HE CAN. Sep 10 07:54:30 i hope that was unpleasant! Sep 10 07:55:34 Russ, now you ahve me worried Sep 10 07:55:40 becuae thats the same photo Sep 10 07:55:42 for anotehr auction Sep 10 07:56:03 you don't use google image search when you ebay? Sep 10 07:56:15 no. Sep 10 07:56:18 doh. Sep 10 07:56:23 that's a pretty good idea. Sep 10 07:56:47 unless you're buying twinkies. Sep 10 07:58:30 it's 1am, and i'm still at work, but damn things are goin well :DD Sep 10 08:03:12 why are you at work at 1am Sep 10 08:03:13 ? Sep 10 08:05:58 hello! ok I get the following error: /usr/lib/gcc/arm-angstrom-linux-gnueabi/4.7.3/../../../../arm-angstrom-linux-gnueabi/bin/ld: cannot find -lmysqlclient_r Sep 10 08:06:29 does that mean its looking for libmysqlclient_r.so in /usr/lib/gcc/arm-angstrom-linux.... etc etc??? Sep 10 08:06:32 cverster, wow. you've just foudn the goldne ticket Sep 10 08:06:55 if you submit that error to the competition, you'll win USD$100,000 Sep 10 08:07:13 whooop. yayayay. Sep 10 08:07:57 k enough with the jokes. I have mysqlclient_r.so and .la in /usr/lib, dont know why its not picking that up Sep 10 08:08:09 No, i'll choose when we finish the jokes Sep 10 08:08:34 How many mysql errors doe it take to change a lightbulb Sep 10 08:08:39 Knock Knock Sep 10 08:08:40 whos there Sep 10 08:08:44 SQL error Sep 10 08:08:44 mysql Sep 10 08:08:49 mysql who Sep 10 08:08:52 mysql error Sep 10 08:09:00 cverster: libname is not always equal to soname. so check the known flags with pkg-config --list-all for example Sep 10 08:09:10 [kernel] koenkooi pushed 1 new commit to 3.12: http://git.io/_EF-Gg Sep 10 08:09:10 kernel/3.12 7a62233 Koen Kooi: 3.12: update to latest mainline, resolve merge conflicts... Sep 10 08:09:31 Ahhh, linux talk, LetoThe2nd that just went over my head Sep 10 08:09:38 assuming that this lib has pkg-copnfig files, of course. Sep 10 08:09:52 and you use correct pkg-config :p Sep 10 08:10:03 not from the host, but for the target Sep 10 08:10:25 ynezz: true that. Sep 10 08:10:34 read more about linker library paths Sep 10 08:10:54 kwaai Sep 10 08:11:11 cverster: it would be of no use if your arm cross compiler would go look in the x86 library folders like /usr/lib... Sep 10 08:11:26 cverster: care to actually work in solving your problem? Sep 10 08:11:32 yes Sep 10 08:11:59 cverster: so. you are trying to crosscompile, right? Sep 10 08:12:02 im trying. I read a bit and in my head if my .so and .la file is in /usr/lib it should work Sep 10 08:12:04 no Sep 10 08:12:11 not crosscompile, compiling from source Sep 10 08:12:36 I see angstrom = crosscompile Sep 10 08:12:44 cverster: *what* are you trying to compile on *which* boc using *which* toolchain? Sep 10 08:13:22 I'm trying to compile the mysql c++ connector from the source they provided. I used cmake and am now trying to "make" their source code Sep 10 08:13:52 nonsense and the answer to what i asked you. Sep 10 08:14:22 ? Sep 10 08:14:28 let me repeat. Sep 10 08:14:28 im using GNU compilers ? Sep 10 08:14:34 10:12 < LetoThe2nd> cverster: *what* are you trying to compile on *which* boc using *which* toolchain? Sep 10 08:14:58 ok, just expand "boc" for me Sep 10 08:15:10 so that i can google it Sep 10 08:15:19 cverster: your paste says something about arm-angstrom-something. so you are trying to use that compiler, probably. Sep 10 08:15:36 the default gcc on angstrom Sep 10 08:15:37 cverster: *sigh* boc = box, just a typo one key right. Sep 10 08:15:48 haha ;) Sep 10 08:15:59 gcc compiler on Angstrom Beaglebone black Sep 10 08:16:04 cverster: so you are compiling *on* the beaglebone black? Sep 10 08:16:10 yip Sep 10 08:16:44 can you please patebin the complete chain of commands that you used? Sep 10 08:17:00 cverster: note: pastebin, *not* dump in here! Sep 10 08:17:05 :P Sep 10 08:18:09 I literally downloaded the source from here: http://dev.mysql.com/downloads/connector/cpp/#downloads. Then I typed "cmake ." and then "make". I hacked some source files as errors popped up, they were missing includes and trying to execute printf Sep 10 08:18:26 so I typed two commands in total Sep 10 08:19:37 sorry I dumped in here, but I didn't want to pastebin two lines :D Sep 10 08:25:00 LetoThe2nd: Hold on, i think i might be on to something. MySQL is giving errors aswell, so im gonna reinstall it Sep 10 08:25:39 cverster: ok, first thing - i just built that thing here on x86-64. *NO* errors whatsoever concerning printfs or such. so i'm pretty sure you are doing something fishy, and *not* building that thing as intended. Sep 10 08:26:15 really? but how? I mean, I literally take the source and "cmake ." then "make" Sep 10 08:26:20 where is the room for fishy? Sep 10 08:26:25 cverster: i have no idea, you tell me. Sep 10 08:26:43 cverster: my bets still are on that you are messing up your boxes. Sep 10 08:26:56 possibly Sep 10 08:27:37 thats why i asked for the complete command chain. including prompt, please. and including a "uname -a", please. Sep 10 08:27:54 but hey, gotta learn somehow. So you just built it like that on BBB? Sep 10 08:28:13 cverster: why are you not listnening? Sep 10 08:28:36 10:25 < LetoThe2nd> cverster: i just built that thing here on x86-64. Sep 10 08:29:16 I am listening. But my semi-technical brain does not register all of your lingo, im trying, really. Sep 10 08:30:10 cverster: start from a fresh checkout and pastebin the whole thing Sep 10 08:30:20 until the first error comes up Sep 10 08:30:26 cverster: then you should better back off from your current task an learn the basics first. handholding someone who does not even know the most trivial things is just tiresome. Sep 10 08:30:44 .. and pointless, as the basics are all well documented. Sep 10 08:30:59 * LetoThe2nd hands over to av500 for now, got some other work. Sep 10 08:31:41 LetoThe2nd: nah, I got bone to grind Sep 10 08:31:58 av500: me got grinds to bone? Sep 10 08:32:57 mrpackethead: deadline tomorrow :D Sep 10 08:33:08 do you own the copany? Sep 10 08:33:12 company Sep 10 08:33:54 no. i had a fight with a library that put me behind. Sep 10 08:34:10 so, if you dont' own the company Sep 10 08:34:15 why are you working your arse off Sep 10 08:34:48 for the lulz Sep 10 08:35:01 because this is a real deadline. Sep 10 08:35:17 like, shit comes back from the foundary, and what i'm working on is the only way to communicate with it. :D Sep 10 08:35:35 *foundry Sep 10 08:35:49 another corporate slave Sep 10 08:36:07 people who thing they will get ahead by letting the boss take them for everthing Sep 10 08:36:14 startup, we're not a corporation. :P Sep 10 08:36:29 nah, i said i could do it by now, slacked for a while Sep 10 08:36:35 so i'm working hard now to make up for it. Sep 10 08:36:54 ahh, i feel so enlightened now. "people who thing" - really thanks mrpackethead for sahring this wisdom with us. Sep 10 08:37:05 what starts up must come down Sep 10 08:37:07 and, it's more about having a room full of engineers twiddling their thumbs waiting for me. Sep 10 08:37:26 true, but sometimes that happens after an aquisition Sep 10 08:37:31 :) Sep 10 08:38:07 * LetoThe2nd goes back to thinging. Sep 10 08:38:48 LetoThe2nd: thinging dirty thongs? Sep 10 08:39:05 av500: dirty deeds done dirt cheap. Sep 10 08:39:51 * av500 waits for the postman to bring tape loops Sep 10 08:40:14 or fruit loops Sep 10 08:45:05 Hi, I want to fix register values in pwm device, by using Python, not using console command. I know there are some way to fix /sys/kernel/debug/omap_mux but unfortunately, I couldn't use that way. Is there any other way to make it? Sep 10 08:45:30 Guest64177, why would you need to fix register values in pwm device? Sep 10 08:46:02 also, ompa_mux might be gone Sep 10 08:46:08 if you are using a recent kernel Sep 10 08:46:41 *oompa_loompa_mux ? Sep 10 08:46:51 Panto, To fix duty_cycle and frequency in pwm Sep 10 08:47:09 why? god why? Sep 10 08:47:25 the recent kernels have sysfs attribute interfaces Sep 10 08:47:38 just cat to the files the values, and you're done Sep 10 08:47:38 to control DC motoer Sep 10 08:47:53 sysfs? could you elucidate it? Sep 10 08:47:53 http://lwn.net/Articles/553755/ Sep 10 08:48:03 OK thanks I will look that document Sep 10 08:48:13 that's a funny word to use. Sep 10 08:51:01 hello everybody, spricht hier jemand deutsch? Sep 10 08:51:11 Panto, I can see files in /sys/class/pwm/pwmchipN/ but I can't find /sys/class/pwm/pwmchipN/pwmX/* :( although I could see pwm_p8/p9 is setted when I typed "cat /sys/devices/bone.capemgr.7/slots. Sep 10 08:51:44 Maveik57: nein, nur Englisch Sep 10 08:52:45 ich bin sicher niemand hier kann Deutsch Sep 10 08:53:26 und du? Sep 10 08:53:53 Maveik57: the channel language is english Sep 10 08:54:06 talking German will greatly reduce the number of people that might help you Sep 10 08:58:52 Guest64177, use the latest version of the releases always Sep 10 08:59:01 looks like an older release Sep 10 08:59:25 Can someone tell me, how I can install a Linux Programm who called ARDESIA on the Baeglebone Black. I`m not a Linux Expert and exuse my bad English Sep 10 09:01:06 panto, I use 3.8.13 kernel with xenomai patched -- it may be reason, I just want to know it comes from kernel or some others. Thank you :) Sep 10 09:13:20 mrpackethead: actually, i was quite late Sep 10 09:14:23 ahh Sep 10 09:16:20 but yes, chocolate is a good idea Sep 10 09:18:11 I bought a Mantis today Sep 10 09:18:11 but Russ, has me worreid Sep 10 09:18:11 because the auction i won Sep 10 09:18:23 has the same photo as another one on ebay Sep 10 09:18:30 mantis? Sep 10 09:19:03 https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-ash4/1268731_10151858833832661_467444346_o.jpg Sep 10 09:20:18 there is a us shop that builds such microscopes quite cheaply and has some stock they want to get rid of Sep 10 09:20:38 300usd for a quite nice one... but shipping would cost more than the microscope itself :-( Sep 10 09:21:09 * KotH sighs Sep 10 09:21:24 it's 2013, and irc has still the same splits as it did in the 90s Sep 10 09:23:22 they have enlargement surgery KotH Sep 10 09:23:25 just fyi Sep 10 09:23:34 no need for a microscope Sep 10 09:23:50 here, have a cookie... Sep 10 09:23:57 now go play somewhere else Sep 10 09:23:58 ;) Sep 10 09:24:31 KotH: got a link? Sep 10 09:24:57 the mantis stuff is very good Sep 10 09:25:01 you can use it all day Sep 10 09:25:05 and not get a head-ache Sep 10 09:25:58 mrpackethead: http://www.ebay.com/usr/bargainmicroscopes Sep 10 09:26:15 mrpackethead: they seem to use ebay to sell off their leftover stuff Sep 10 09:26:24 mrpackethead: i dont know how good their microscopse are Sep 10 09:26:26 ok, different Sep 10 09:26:31 two eye peice stuff Sep 10 09:26:40 mrpackethead: but as i wanted to buy them for home use, long working hours wouldnt be a problem Sep 10 09:26:42 the mantis eats them Sep 10 09:27:04 the magnification on those is way too high as well Sep 10 09:27:11 yeah Sep 10 09:27:13 you only want 6-10x for pcb work Sep 10 09:27:19 at most Sep 10 09:27:32 have you soldered at 10x? Sep 10 09:27:45 it takes a little bit to get the hand / eye thing going Sep 10 09:28:04 the nice thing is that i can see what im doing as i'm doing it Sep 10 09:28:08 under the mantis Sep 10 09:28:11 we usually solder at 10x and 25x Sep 10 09:28:41 what are you soldering? Sep 10 09:29:04 wires to gates Sep 10 09:29:08 whats funny, is that you get to see how bad soldering really is Sep 10 09:29:08 single electrons Sep 10 09:29:13 +1 Sep 10 09:29:20 we have a stereo scope here Sep 10 09:29:26 nice toy Sep 10 09:29:28 even then best machine stenciled and perfectly placed parts Sep 10 09:29:36 actually look terrible Sep 10 09:29:37 :) Sep 10 09:29:49 soldering is such an imprecise technique Sep 10 09:29:58 lucky, its pretty accomodating Sep 10 09:30:29 I've at home Bresser Biorit ICD CS 10x Sep 10 09:30:56 mrpackethead: anything from 0603 to 0.5mm qfn's Sep 10 09:30:59 quite happy with it Sep 10 09:31:07 oh. Sep 10 09:31:11 same as me Sep 10 09:31:12 mrpackethead: for inspection we go sometimes even to 50x Sep 10 09:31:26 i find that 6 or 10x is more than enough Sep 10 09:31:29 for 0603 you don't need scope... Sep 10 09:31:30 mrpackethead: but that requires a steady hand :) Sep 10 09:31:42 maybe its because i've got telescopic bat-man eyes Sep 10 09:31:57 ynezz: not for soldering, yes. but with a scope you are faster and you dont have to check the solder joints later Sep 10 09:31:59 we have a Hund on a long boom and a fiber light Sep 10 09:32:13 KotH: sure Sep 10 09:32:23 owen is faster Sep 10 09:32:29 owen? Sep 10 09:32:47 mrpackethead: you know, i'm old and my eyesight is bad Sep 10 09:32:52 lol. Sep 10 09:32:53 yes, stencil + owen Sep 10 09:32:55 but agree. Sep 10 09:33:00 its just about time Sep 10 09:33:06 ynezz: oven? Sep 10 09:33:10 you can solder and check at the same time. Sep 10 09:33:17 oh you grammar nazi! Sep 10 09:33:26 ynezz: orthorgraphy, not grammar Sep 10 09:33:28 oven is faster but not always useful. Sep 10 09:33:29 er... Sep 10 09:33:33 orthography Sep 10 09:33:56 ynezz: its not faster if i need to wait for a stainless steel stencil Sep 10 09:34:05 ynezz: owen is a name, oven is a thing ;) Sep 10 09:34:10 I liked Mickael Owen Sep 10 09:34:29 mrpackethead: you get one for free with your order on beta-layout Sep 10 09:34:29 I can not get reliable stenciling out of Laser cut plastic for TQFP's Sep 10 09:34:45 ynezz: and it takes how long to get the PCB? Sep 10 09:34:52 it's half past 11 and i have not done anything yet. looks like this will be a very productive day... again Sep 10 09:35:08 mrpackethead: standard is about 8 working days Sep 10 09:35:12 mrpackethead: too fin pitch? Sep 10 09:35:18 mrpackethead: but you can pay for express :) Sep 10 09:35:25 ynezz: i need about 8 minute turn around Sep 10 09:35:28 8 days is an age Sep 10 09:35:36 What i do, is cut a plastic one Sep 10 09:35:47 take out anything too small Sep 10 09:35:59 stencil and oven all the jellybeans Sep 10 09:36:02 ynezz: mrpackethead is a fast turn over time electronics developer. he does electronics how other people do software :) Sep 10 09:36:32 seems so Sep 10 09:36:54 * KotH must do a trip to .nz someday Sep 10 09:37:06 visit this mrpackethead guy, and the lobster Sep 10 09:37:07 What i was finding is that the laser cut mylar jsut si'nt good enough Sep 10 09:37:20 and you get a mess Sep 10 09:37:29 mrpackethead: how about cutting 0.2mm stainless steal? Sep 10 09:37:39 mrpackethead: or do you need a higher power laser for that? Sep 10 09:37:51 it quicker to hand solder than clean up Sep 10 09:37:57 s/steal/steel/ Sep 10 09:38:10 I've never tryed, but i only have a 60W laser Sep 10 09:38:27 i doubt it would would even mark the steel Sep 10 09:38:28 :-) Sep 10 09:38:43 the lasers they use for the stencils are YAG's Sep 10 09:38:49 our laser is CO2 Sep 10 09:39:02 hmm.. CO2 should work on steel as well Sep 10 09:39:05 and i think you need a bit more precision than we have as well Sep 10 09:39:11 it does, if you have enough power Sep 10 09:39:16 I'll give it a go Sep 10 09:39:23 find some old stencil Sep 10 09:39:26 and see what happens Sep 10 09:39:29 buy one of those kW class CO2 laser tubes on ebay, and try it Sep 10 09:39:44 yeah. Sep 10 09:40:10 i like hte fact that my laser is in a box that is laser proof Sep 10 09:40:16 so, even if somethibn bad happens Sep 10 09:40:30 a stray beam deos'nt go randomly out and hit somerthign Sep 10 09:40:53 you mean your whole setup is in a closed box? Sep 10 09:40:58 the laser alone is not important Sep 10 09:41:05 it doesn't have much stray field anyways Sep 10 09:41:13 the beam is the dangerouse stuff Sep 10 09:42:34 yes, Sep 10 09:42:47 its the beam that worries me Sep 10 09:42:55 if it reflects off soemrthign Sep 10 09:43:00 it should already worry you at 60W Sep 10 09:43:11 thats why you cna't run it Sep 10 09:43:18 without the lid closed! Sep 10 09:43:27 there is a 10mm polycarbonate window in the lid Sep 10 09:43:44 I did a demostration for my staff Sep 10 09:43:50 of why we should be careful with lasers Sep 10 09:44:02 * KotH wouldnt trust any window with >1W lasers Sep 10 09:44:09 get a 1" thick peice of steak Sep 10 09:44:15 no tatoo? Sep 10 09:44:21 the laser will slice it nicely Sep 10 09:44:22 :-) Sep 10 09:44:43 ynezz: i've seen trains of spots on a wall in a laser lab.. that was a low power ps laser... Sep 10 09:45:04 ynezz: now guess what a CW laser would do Sep 10 09:45:11 KotH: 60W C02 lasers wont' cut polycarbonate much more than surface deep Sep 10 09:45:15 ynezz: and then extrapolate to high power lasers Sep 10 09:45:53 teh rest of the system is steel Sep 10 09:46:03 but the steak demostration is graphic Sep 10 09:46:05 KotH: we've laser here too, but it's boring one, cutting just labels... Sep 10 09:46:12 mrpackethead: i am not worried about cutting, i'm worried about what passes trough the window Sep 10 09:46:14 I might have to get some sheep eyeballs. Sep 10 09:46:22 KotH: Next to nothing Sep 10 09:46:33 mrpackethead: ok, CO2 is 10u and that's quite far away from visible, but still... Sep 10 09:46:33 * av500 does not have a laser, but knows a guy that has :) Sep 10 09:46:55 av500: i'm pretty sure you own a cd or dvd player ;) Sep 10 09:47:39 KotH: no, the real thing Sep 10 09:47:39 I've modifyed our laser to have ain inbuilt CO2 fire exhingshiser Sep 10 09:47:49 uni has a laser cutter and I know the guy that operates it :)( Sep 10 09:48:02 hav'nt used it in anger Sep 10 09:48:03 :-) Sep 10 09:48:11 mrpackethead: iirc 10u does not pass the cornea. but burns on the cornea are pretty bad for your sight as well Sep 10 09:48:20 yeah. Sep 10 09:48:29 its why we have Laser googles Sep 10 09:48:48 but it would be pretty nasty burns on skin as well Sep 10 09:49:10 this is close to what we have: http://www.ebay.com/itm/3X-70X-STEREOSCOPIC-BINOCULAR-MICROSCOPE-WITH-BOOM-STAND-/251336665209?pt=LH_DefaultDomain_0&hash=item3a84d52879 Sep 10 09:49:27 in form factor Sep 10 09:49:36 rumour is that ubuntu 14.04 will be nicknamed Transsexual Troll.... Sep 10 09:49:49 https://wiki.ubuntu.com/DevelopmentCodeNames#T Sep 10 09:50:54 my neiboghr had a company called lastercrafts ( http://lasercrafts.nl/web/ ) and I have the 3d printer. I am thinking of playing with scanning e.g. using something as simple as http://www.makerscanner.com/ so I need a smaller laser now Sep 10 09:51:03 and Linux share of the market would increase by 4% Sep 10 09:51:10 to clone kids Sep 10 09:51:19 how much is 4% of nothing? Sep 10 09:53:01 I wonder why I fail at using the BB's for all these projects Sep 10 09:54:28 probably because my laptop is good enough[tm] Sep 10 09:56:11 woo! my shit works! I'm going to sleep! Sep 10 10:08:13 Does anyone know where, exactly, in uEnv.txt on a Beaglebone Black I should put "capemgr.enable_partno=ADAFRUIT-SPI0" Sep 10 10:08:26 SPI works great if I spool it up manually, but it's a little arduous to do every boot Sep 10 10:09:10 And if it's pertinent, I'm working on Ubuntu armhf 3.8.13-bone20 Sep 10 10:14:42 Also, hello, I've connected a breadboarduino to my Beaglebone Black and successfully flashed a new binary to it Sep 10 10:35:38 Gadgetoid: sounds like kernel cmdline Sep 10 10:39:29 hello Sep 10 10:40:08 just buying an hdmi adapter for beaglebone black. do I need an 1.4 cable, or 1.3 it's just fine? Sep 10 10:41:21 samael: where are you based? Sep 10 10:41:39 Gadgetoid: italy Sep 10 10:41:55 Ah, would have recommended a specific one that I've bought and tried myself otherwise Sep 10 10:42:41 samael: updated HDMI specs are for things like ethernet and 3d, you could hook the beaglebone up with spaghetti and it'd work I suspect Sep 10 10:43:31 Actually 1.3 was just to support WQXGA which you'll never get out of a Beaglebone Black anyway, so 1.3 or even 1.0 is fine Sep 10 10:44:18 ok. being a complete ignorant about video stuff i just wanted to be sure. Sep 10 10:44:21 thanks a lot! Sep 10 10:45:00 samael: I was ignorant of mini/micro HDMI, so my main worry was getting one with the right connector on the end, I didn't even spare version numbers a thought Sep 10 10:45:11 Gadgetoid: furthering your noodly agenda I see ;-) Sep 10 10:45:17 Full-sized HDMI would have been nice, though! Sep 10 10:45:44 XorA: Rumbled! Spaghetti jump wires are the best, guaranteed never to short Sep 10 10:46:29 dm8tbr: you are correct, but sticking it in what looks like the right place has no effect... I suspect it's secretly conflicting with HDMI somehow, although I thought that was just SPI1 and not SPI0 Sep 10 10:47:03 c Sep 10 10:47:41 I'm trying to adapt my Pico PiDuino tutorial for use with the Beaglebone Black too Sep 10 10:47:54 Although I'm not sure what you'd call a fusion of a BBB and an Arduino Sep 10 11:02:20 Next step is getting them talking over Serial Sep 10 11:18:04 Anybody has a decent guide on how I can remotely debug a c/c++ program with Eclipse on bbb? Sep 10 11:18:46 remote? look at it with a spyglass during an eclipse := Sep 10 11:18:50 *SCNR* Sep 10 11:20:49 Yes, with gdbserver Sep 10 11:24:08 RagBal: why not run gdb on the bbb itself? Sep 10 11:24:28 * KotH was never fond of the debugging capabilities of eclipse Sep 10 11:24:36 Because I want to debug from an IDE =) Sep 10 11:24:49 they always felt like i was ponding a stone with a straw Sep 10 11:25:53 Well it could be a configuration issue in Eclipse though, it's a nightmare to configure it correctly to cross compile for angstrom Sep 10 11:26:04 At least, for me it's a nightmare Sep 10 11:27:59 koen, what are the chances of updating conamn in Angstrom? Sep 10 11:28:19 RagBal: cross compilation with eclipse is easy Sep 10 11:29:01 RagBal: debugging c with eclipse needs to be properly configured and it's not obvious how to do that w/o having a tutorial or having read the complete eclipse documentation Sep 10 11:29:07 Yes, but when I want to debug stuff it needs all the sysroot files, and there is no easy configuration for that it seems Sep 10 11:29:17 RagBal: use gdb directl Sep 10 11:29:30 it works, no pain with configuration and there is no eclipse that gets into your way Sep 10 11:30:15 True, but still I want it to work =) Sep 10 11:31:26 http://hertaville.com/2012/09/16/part-3-debugging-openocd-0-6-0/ Sep 10 11:31:28 read that Sep 10 11:31:52 it is a step by step intro into debugging with openocd, which is similar as to use remote gdb Sep 10 11:32:17 Hmm will read, thank you! Sep 10 11:33:13 RagBal: send your thanks and good swiss chocolate to woglinde Sep 10 11:33:18 Crofton|work: conamn? Sep 10 11:33:31 connman how ever ou spell it :) Sep 10 11:33:34 cfo is asking Sep 10 11:33:40 wants the command line util Sep 10 11:33:58 Crofton|work: which version does he need? Sep 10 11:34:10 I would assume what ever is in master Sep 10 11:34:25 is it an easy update, or does it break lots? Sep 10 11:35:19 there's 1.4 in v2012.12 and 1.12 in v2013.06 Sep 10 11:35:25 find out which version he needs first Sep 10 11:35:29 k Sep 10 11:36:02 Anyhow... if I read it right... connmanctl should be included in the 1.12 (i.e. since version 1.7) Sep 10 11:36:26 so swithcing branches to 2013.6 helps Sep 10 11:36:30 default is older? Sep 10 11:38:51 yes, default is v2012.12 Sep 10 11:39:13 how do you switch? Sep 10 11:39:28 * Crofton|work has not completed coffee drinking Sep 10 11:40:29 edit DISTRO=? Sep 10 11:40:37 in local.conf Sep 10 11:41:01 git clone https://github.com/Angstrom-distribution/setup-scripts.git ; cd setup-scripts ; git checkout origin/angstrom-v2013.06-yocto1.4 angstrom-v2013.06-yocto1.4 Sep 10 11:41:19 for an existing checkout just change banches? Sep 10 11:41:37 and do 'oebb.sh update' to fix the repos Sep 10 12:05:45 hello. i am experimenting with the touchscreen jitter problem. now I have tweaked /etc/ts.conf to pass through values only e.g. > 200. this makes the jitter disappear Sep 10 12:07:28 why not use the 16x averaging feature in the hardware? Sep 10 12:07:50 the problem is that the touchscreen seems to deliver different pressure values in the different parts, while the upper left part delivers pressure > 300 the lower right part does not deliver values more than 180 Sep 10 12:09:48 i read the pressure values directly from the driver afaik, i use evtest Sep 10 12:10:06 koen: i am not an expert and i am not sure where to turn on this averaging in the driver :-( Sep 10 12:12:09 is it normal that the pressure values vary that much in different parts of the touchscreen? Sep 10 12:58:02 Hi. I've bought a beaglebone (white). How can I use serial connection on it? There isn't a com port like on beagleboard-xm Sep 10 12:58:52 The USB gadget port does serial on white Sep 10 12:59:02 on black you need a separate FTDI cable Sep 10 13:00:07 For usb gadget you mean the mini-usb port? Sep 10 13:00:12 USB gadget also does serial on Black Sep 10 13:00:49 yes, mini is a usb composite device - serial + eth-over-usb + mass storage Sep 10 13:01:53 mmh, so this zigbee thing works from my phone ... I got two power outlets and one of my colleagues is not here today hehehe Sep 10 14:29:00 hi Sep 10 15:29:30 hi Sep 10 15:30:15 Can anone please tell me from where can i get Prebuilt android images for Black beaglebone board Sep 10 15:34:18 any body please reply Sep 10 15:35:10 sam_: http://icculus.org/~hendersa/BBB_JB_Android_3_8_13.img.bz2 Sep 10 15:35:22 you can just google, just saying Sep 10 15:37:56 thanks for your reply. But it will allow me to flash nand memory or i have create sdcard for that? Sep 10 15:38:32 read their instructions Sep 10 15:39:32 hey guys Sep 10 15:39:47 just got a beaglebone, trying to put ubuntu on it Sep 10 15:39:57 any tips, suggestions would be highly appreciated Sep 10 15:40:43 sam_: just sdcard Sep 10 15:44:16 C2H6O_: my tips: 1. put ubuntu on microsd, 2. put microsd in beaglebone, 3. connect cables Sep 10 15:45:01 sounds about right Sep 10 15:45:16 step 0 buy a serial debug cable / module Sep 10 15:57:13 can I load ubuntu directly onto eMMC? Sep 10 16:00:30 C2H6O_: yes Sep 10 16:30:38 Hello People Sep 10 16:35:55 I received yesterday my BEAGLEBONE black but I can not install gnumeric. Is it possible? Sep 10 16:39:16 its 2013 Sep 10 16:39:20 anything is possible Sep 10 16:39:30 please define "can not install" Sep 10 16:40:26 av500 hehehe, it's true Sep 10 16:40:32 well... How I install gnumeric? Sep 10 16:41:05 There is no facility manager in angstrom? Sep 10 16:41:56 opkg install gnumeric Sep 10 16:42:24 nothing happens when I type this Sep 10 16:42:30 opkg update Sep 10 16:42:46 opkg list Sep 10 16:43:47 Hmm .. I'll try, but I need to disconnect here to connect the beagle. Sep 10 16:43:56 ? Sep 10 16:44:09 get a network switch Sep 10 16:44:19 saves you from a lot of pain Sep 10 16:45:23 KKKKK. I have, but is that my wi-fi adapter broke. Sep 10 16:53:06 hiya folks, I read recently about patches to get 3.12 booting, but usb peripherials were unhappy.... does that means the ethernet too? Sep 10 16:54:04 av500 yeah :) worked! Sep 10 16:57:05 I want to translate it to Portuguese of Brazil. Sep 10 17:27:04 Does anyone know of a VM / Emulator for the Beagle boards? I would like to run a VM of it so I can mess around. Sep 10 17:30:14 FWIW I'm using VirtualBox. Sep 10 17:31:34 I think running VMs on the bone is going to mkae you have a bad time. Sep 10 17:31:38 THat said, xen might work. Sep 10 17:35:37 no it won't Sep 10 17:36:08 A8 doesn't have the virt extensions Sep 10 17:37:10 OK. Sep 10 17:42:44 mru: Xen does not require VT. THat is the entire point of xen. Sep 10 17:45:28 agmlego: but it profits greatyl from it Sep 10 17:45:43 What is Xen? Sep 10 17:45:46 does user mode linux still exist? Sep 10 17:46:00 VirG: Google. Sep 10 17:46:17 VT is an x86 thing Sep 10 17:46:18 KotH: Sure, any virtualisation benefits. But xen does not *require* it. Sep 10 17:46:46 agmlego: for what is worth, neither does qemu require any help for virtualization Sep 10 17:46:53 True. Sep 10 17:46:59 I haven't heard of any arm vm that doesn't need the virt extensions Sep 10 17:47:08 I have had bad experiences with qemu myself, but I know others use it OK. Sep 10 17:47:40 qemu can also do full emulation Sep 10 17:48:03 I already did. However, I do not see the relationship. I am guessing that Xen is a middle layer on which VMs can be created ... or something like that. Sep 10 17:48:38 xen is a hypervisor of sorts Sep 10 17:49:01 VirG: xen is a similar piece of software to VirtualBox. Sep 10 17:49:11 If this is the case, I was not aware that VirtualBox and VMWare were using it. Sep 10 17:49:13 ahh. OK. Sep 10 17:49:18 Thank you. Sep 10 17:49:22 iirc it can run a cooperative guest without hw support Sep 10 17:50:06 on x86 Sep 10 17:50:20 I believe I confused everyone. Sep 10 17:50:53 I want to emulate the Beagle on my Win or OSX box. Sep 10 17:51:04 not run a VM on the Beagle. Sep 10 17:51:16 all mentions I've seen of xen/arm have assumed a15 or better Sep 10 17:51:29 MRU: OK. Sep 10 17:51:34 why would you want to do that? Sep 10 17:52:09 So I can mess around with it without the device. I'm in my office right now but the board is in my car. Sep 10 17:52:57 qemu, then. Sep 10 17:52:59 get two Sep 10 17:53:12 qemu sucks Sep 10 17:53:20 Sure. Sep 10 17:53:21 I have four. Two blacks and two bones. Only one is with me though. Sep 10 17:53:41 But it *does* allow emulation of non native architectures, and there might be an A8 setup for it. Sep 10 17:53:57 AGMLego, checking that now. Sep 10 17:54:18 yes, but the real thing is much better Sep 10 17:54:45 VirG: I am amused you got the capitalisation correct in my nick, but I have to tell you...tab-completion works in most clients. Sep 10 17:54:50 MRU: no doubt. I just want ... a staging environment ... Sep 10 17:54:56 mru: No one argues that point. Sep 10 17:55:16 mru: But if the choice is between emulation or nothing at all, the emulation is the better option. Sep 10 17:55:25 AGMLego: I know I know, I don't use it though and usually just type nicknames out manually. Sep 10 17:55:34 meeting time. Sep 10 17:55:44 VirG: It is a good habit to get into. ;-P Sep 10 17:55:49 waiting a day for the real thing beats emulation Sep 10 18:02:43 * KotH needs some sub-20usd embedded linux board Sep 10 18:02:56 good luck Sep 10 18:03:01 so i can fill my whole flat with wireless gadgets! Sep 10 18:05:13 Filling it with chocolate would be cheaper Sep 10 18:06:13 depends on the chocolate Sep 10 18:06:19 (and on the gadgets) Sep 10 18:06:30 filling it with chocolate is definitly more expensive Sep 10 18:06:38 I opened one of these so-called wireless gadgets once, and it had more wires than I could count inside Sep 10 18:06:45 who do you think i am? someone who buys cheap chocolate? Sep 10 18:07:07 mru, ++ Sep 10 18:08:21 meh.. wlan modules cost themselves 20usd in single pieces Sep 10 18:10:05 And a single piece of good chocolate costs more than 20usd? Sep 10 18:10:17 juup Sep 10 18:10:36 you know, usd isnt worth anything these days Sep 10 18:10:43 good chocolate starts from 20chf upwards Sep 10 18:10:58 a box of stuff like cru sauvage is 35chf Sep 10 18:11:21 a "bar" of läderach costs 20-30chf Sep 10 18:11:33 when you buy them directly at the factory Sep 10 18:12:48 O.o Sep 10 18:13:59 Hmmm.... Sure you're not thinking of crack? Sep 10 18:14:57 Do you have problems with people robbing liquor stores to pay for their habit? Sep 10 18:16:08 we dont have liquor stores Sep 10 18:16:25 oh... umm... well... stores? Sep 10 18:16:26 but we have chocolate shops :) Sep 10 18:16:31 heh Sep 10 18:16:51 and no, there is chocolate for all kinds of budgets Sep 10 18:17:10 cheapest start at iirc 4.5CHF for a small 400g bar Sep 10 18:17:43 hmm.. maybe i should buy a couple of those for elce Sep 10 18:17:51 especially for our usian friends ;) Sep 10 18:18:11 thats a bit more reasonable Sep 10 18:20:05 that's the cheap stuff you buy if you cannot afford anything else Sep 10 18:20:20 very few people sink low enough to not even afford that Sep 10 18:20:26 and those buy german chocolate Sep 10 18:23:13 what type of chocolate are we even talking about here? Can you define a range for the percentage cocoa? Sep 10 18:23:44 uhmm. milk chocolate to 99% black Sep 10 18:24:04 the cheap ones are usually milk with the occasional 60-70% Sep 10 18:24:17 it's quality, not quantity Sep 10 18:24:39 and just for the record: just because chocolate has a higher percentage of cocoa doesn't mean it's better Sep 10 18:24:50 usually, it means it's worse Sep 10 18:25:04 most manufacturers mess up when they go over 70% Sep 10 18:25:45 well, dark chocolate is inherently neither better nor worse than milk chocolate Sep 10 18:26:02 I'm assuming all of the cocoa is imported, correct? Sep 10 18:26:04 I prefer milk Sep 10 18:26:13 mru: it's harder to do it right Sep 10 18:26:56 particular specimens can of course be worse Sep 10 18:29:43 I suppose when you talk about quality you're talking about the quality of the original cocoa (and other ingredients) as well as the quality production Sep 10 18:30:54 no, about the quality of the end product Sep 10 18:31:18 the quality of the end product obviously depends somewhat on the quality of the ingredients Sep 10 18:32:02 I was just wondering, because with wine for instance the quality of the product depends almost entirely on the quality of the grapes. Sep 10 18:33:00 what mru said Sep 10 18:33:22 I'm sure you can make bad wine from the best grapes too Sep 10 18:35:29 yeah, but how fast is this chocolate compared to other SoCs Sep 10 18:36:23 it may come in a pretty wrapper, smell and taste great, but at what wattage? Sep 10 18:37:11 mru: I'm sure you could too, but I think it sounds like it would require a higher degree of incompetence than making bad chocolate from bad cocoa. Sep 10 18:37:36 georgem: nope Sep 10 18:37:49 incompetence knows no limits Sep 10 18:37:50 georgem: makeing good chocolate from scratch is actually quite hard Sep 10 18:38:02 georgem: it requires quite some skills to do it right Sep 10 18:38:38 KotH: thats what I was saying actually. Sep 10 18:38:47 georgem: even if you have someone who prepares the raw materials for you and knows how to do that correctly, it's still easy to mess up the cooking Sep 10 18:39:25 KotH: it seems to me like it would be harder to screw up making wine (assuming you had good grapes) Sep 10 18:39:35 juup Sep 10 18:43:58 weeee Sep 10 18:44:00 william@arm:~/test$ node test.js Sep 10 18:44:00 Debian GNU/Linux 7.1 (wheezy) Sep 10 18:44:34 m_billybob: my condolences Sep 10 18:45:01 KotH, watch -> http://www.youtube.com/watch?v=hQVTIJBZook Sep 10 18:45:32 its an hour long ;) Sep 10 18:45:54 i'll watch it on +30% speed :) Sep 10 18:46:50 "most people who hate javascript dont know the language well and try using it while not knowing how javascript works" or some such quote Sep 10 18:47:10 fwiw i am not liking js much me self right now - hence i dotn know itwell either Sep 10 18:47:11 i dont have anything against js in itself Sep 10 18:47:28 I do Sep 10 18:47:32 i think js is not bad as an interpreted programming langugae to be executed in a webbrowser Sep 10 18:47:59 but i dont think it's the right choice to be used to write a server process Sep 10 18:48:31 KotH: see if this changes your mind: http://www.phpied.com/3-ways-to-define-a-javascript-class/ Sep 10 18:48:34 perfect fitfor this device. single thread and asynchonous Sep 10 18:50:03 i know c++,nothing can shock me anymore Sep 10 18:50:46 C++ doesn't even compare. it had some thought put into it prior to being created Sep 10 18:51:05 same for js Sep 10 18:51:41 georgem, any language can be bad. it is the developer responcability to write good code Sep 10 18:52:30 m_billybob: If the language is missing simple constructs and forces the developer to devise custom hacks to compensate the language is bad Sep 10 18:52:42 me . . . i hate perl with a passion, but i know there are people out there using it, and making good code / money using it too Sep 10 18:52:44 georgem: do you know erlang? Sep 10 18:53:04 m_billybob: perl is my favorite tool language Sep 10 18:53:18 m_billybob: anything is easy with perl (if it doesnt involve processing binary files) Sep 10 18:53:23 KotH: nope Sep 10 18:53:40 KotH i've a friend who makes ~160k / year writing perl code Sep 10 18:53:57 KotH: perl is kind of the opposite of javascript. There are too many ways to do things Sep 10 18:53:59 * KotH is definitly doing something wrong Sep 10 18:54:15 m_billybob: can you ask your friend how he got that job? Sep 10 18:54:50 KotH hes been a contractor for years, one of the notable contracts that I remember was for amazon Sep 10 18:56:12 If you're good with Perl you can get stuff done with it quicker than almost any language. In some cases if you're able get things done really fast that might be more important than other considerations and could earn you a lot of money Sep 10 18:56:16 KotH I can tell you. years of experience plus putting his resume out / talkign with recruiters. Sep 10 18:56:34 i know because i asked him for someone else recently lol Sep 10 18:57:32 I just throw python at stuff.. Sep 10 18:57:50 I throw whatever makes sense to me at a project Sep 10 18:58:19 Python? Kill it with fire Sep 10 18:58:33 in this case right now nodejs + javascript + native C/C++ seems to be about the right mix Sep 10 18:58:37 If you had a client that was switching for some proprietary system to another (think accounting system or health record management or something) all they care is that the system is converted over. If you can do that really quick in Perl no one will care what language you did it in and you can pocket the money and move on to next job. Sep 10 18:59:08 georgem assuming the developer in question *knows* perl Sep 10 18:59:25 i might do a job best suited in another language becaue i dont know perl Sep 10 18:59:31 and i may be able to do it just as fast Sep 10 18:59:36 and jus tas well Sep 10 18:59:53 georgem: i'm not good at perl, but data munging is still increadibly quickly written Sep 10 19:00:13 georgem: i even once wrote a half assed vhdl parser in an afternoon just using regexp Sep 10 19:00:27 javascript is quickly catching up to perl in that regard me thinks Sep 10 19:01:51 python is visual basic for linux Sep 10 19:02:05 fwiw, personally I like a language that is spoken nearly like english Sep 10 19:02:10 davr not even close. Sep 10 19:03:30 I prefer Python Sep 10 19:03:50 cobol is spoken nearly like english Sep 10 19:03:56 But I can see how people could make a crap load of money with Perl Sep 10 19:04:07 first visual basic is a compiled language, where python may be able to be compiled but not originally, and it is my own opinion, but i do not exactly know python very well internally, but visual basic has many flaws Sep 10 19:04:40 the only flaws i know of about python, is that it forces you do use indentation Sep 10 19:04:51 which isnt necessarily a bad thing Sep 10 19:04:55 m_billybob: right Sep 10 19:05:08 How can I translate my beaglebone? To Portuguese Brazil Sep 10 19:05:47 GeorgeHenrique -> dpkg-reconfigure locale <---- dont knowif this will work on angstorm but will for debian/ubuntu Sep 10 19:05:54 Python's weakness is execution speed Sep 10 19:06:18 vs compiled and JIT Sep 10 19:06:34 georgem most inteprited language now days run pretty close if not as close as native code Sep 10 19:06:49 well this holds true on windows, cant say about linux Sep 10 19:06:52 A lot do. But not Python Sep 10 19:06:58 no ? Sep 10 19:07:43 i do notice more CPU usage though with JIT languages Sep 10 19:07:49 http://benchmarksgame.alioth.debian.org/u32/performance.php Sep 10 19:07:53 even on the ones just asfast Sep 10 19:09:04 JavaScript V8 #2 42.14 42.23 8,016 1527 0% 0% 0% 100% Sep 10 19:09:18 i knew somethign was up but you kow what else georgem ? Sep 10 19:09:43 this is all going to be subjective from system to system and various other factors Sep 10 19:09:57 thats why you can narrow some of the parameters Sep 10 19:09:57 no doubt C is goign ot be fast but where is the asm listing ? Sep 10 19:10:25 and wow ADA kicks butt Sep 10 19:11:22 georgem, there are python compilers thugh right ? Sep 10 19:11:38 as in to native code Sep 10 19:11:44 change the benchmark to get a better idea. if you know what kind of algorithms you'll be using you can pick benchmarks Sep 10 19:12:19 ah' Sep 10 19:12:28 not really. There are a few projects but I think they are still experimental Sep 10 19:12:56 well the older i get though also, ive gotten more into sometimes fast enough is . . .fast enough Sep 10 19:13:07 fast is good in some thigns but not always needed Sep 10 19:13:30 sometimes its how fast it takes to write the program, not how fast the program runs that counts :) Sep 10 19:13:47 and thats how perl can end up making some people lots of money Sep 10 19:13:55 or what makes the most sense for a given project Sep 10 19:14:03 well yes Sep 10 19:14:26 I have two other options id use for my bbb appliance, and neither one seems to be up for the job Sep 10 19:14:28 certainly many considerations Sep 10 19:14:41 mostly due to not having arm compatible code Sep 10 19:15:05 snorkle <--- embedded web server SDK would be #1 on my list Sep 10 19:15:20 .NET / Mono <--- would be #2 Sep 10 19:16:52 Python is good for most cases Sep 10 19:16:59 IMHO Sep 10 19:19:53 Lots of good web frameworks for Python if thats what you're looking for Sep 10 19:22:32 Just don't expect write a fast fourier transform in Python :) Sep 10 19:23:57 to pipe an .xz image to dd is "xz -c image.xz | dd of=/dev/mmcblk1" ? Sep 10 19:27:25 looks right Sep 10 19:27:45 you could just use xzcat too Sep 10 19:31:54 georgem: i`m doing now xz -cd image.img.xz > /dev/mmcblk1 Sep 10 19:31:57 and it`s not working right Sep 10 19:32:22 i want to flash my eMMC like this and it flashed it but seems like the fat partition it`s not good, at least the ROM does not find MLO Sep 10 19:32:49 Umm. I think someone tried to do that earlier and we came to the conclusion that they were using the wrong image file Sep 10 19:33:00 i have good image file Sep 10 19:33:14 2GiB? Sep 10 19:33:18 yup Sep 10 19:34:21 Try dd then (thats what I'd use in the first place) but I don't think it would make a difference Sep 10 19:35:00 need to figure out what is happening Sep 10 19:35:22 check the partitions with fdisk? Sep 10 19:35:26 try mounting them? Sep 10 19:35:35 i am now running angstrom from uSD Sep 10 19:35:43 and the eMMC is *flashed* with what is supposed Sep 10 19:36:24 Reboot off of the uSD again (if eMMC won't boot) Sep 10 19:36:34 http://pastebin.com/KTd3taMQ Sep 10 19:36:38 this is my fdisk -l Sep 10 19:36:42 the partition is there Sep 10 19:36:48 mmcblk1 is eMMC when booting from uSD Sep 10 19:36:59 any idea how can i see the content of the eMMC fat partition Sep 10 19:37:19 i`m a bit noob in linux and how things get mounted here Sep 10 19:37:20 yup Sep 10 19:37:51 mount /dev/mmcblkxx /media/path Sep 10 19:38:02 see if they mount Sep 10 19:38:11 you may have to create the directory in media first or you can create a different path Sep 10 19:38:41 it says that is already mounted Sep 10 19:38:48 mount Sep 10 19:38:53 yup Sep 10 19:38:53 what does "mount" say Sep 10 19:39:05 ah ok then jus tgo to that path Sep 10 19:39:08 give us the output of mount Sep 10 19:39:25 you shouldn't have it mounted if you're reflashing it. then it would be screwed Sep 10 19:39:25 http://pastebin.com/9ubKU5ys Sep 10 19:39:41 no no, i`m flashing when i`m booting from ram Sep 10 19:39:48 booting the chip over usb with a custom ramdisk Sep 10 19:39:51 send image via serial Sep 10 19:39:53 then flash it Sep 10 19:40:03 nothing is mounted in my ramdisk Sep 10 19:40:06 oh ok. umm Sep 10 19:40:09 it`s in /media/BEAGLEBONE Sep 10 19:40:13 the fat partition from eMMC Sep 10 19:40:19 vvu so uenv.txt is good then ? Sep 10 19:40:30 yeah. whats in there Sep 10 19:40:38 root@beaglebone:/media/BEAGLEBONE# ls Sep 10 19:40:39 App Drivers LICENSE.txt README.md autorun.inf uEnv.txt Sep 10 19:40:39 Docs ID.txt MLO START.htm u-boot.img Sep 10 19:40:41 fat is your boot partition Sep 10 19:40:45 sorry for not pastebin it :) Sep 10 19:40:46 ah ok Sep 10 19:40:54 optargs=quiet drm.debug=7 Sep 10 19:41:00 my uEnv.txt Sep 10 19:41:10 so stock Sep 10 19:41:12 I wonder what the time difference REALLY is when toggling a GPIO pin from the PRUSS directly (mode 6 or whatever it is) via R30 ... versus letting it just be a GPIO pin and communicating to it fromt he pruss via the interconnect Sep 10 19:41:24 looks fine to me. Should work assuming the image worked at all Sep 10 19:41:28 10s of nsec ? Sep 10 19:41:35 the image koen provided Sep 10 19:41:50 vvu maybe ping koen, ive heard of this problem before on the groups i think but never heard of the resolution Sep 10 19:42:04 he`s sleeping now i think Sep 10 19:42:10 how can i unmount the eMMC ? Sep 10 19:42:13 perhaps panto Sep 10 19:42:22 umount Sep 10 19:42:22 My friend had a problem with the switch Sep 10 19:42:38 umount /path/to/mount/ Sep 10 19:42:39 I tapped it a few times and it started booting off eMMC again Sep 10 19:42:51 command not found :D Sep 10 19:43:02 umount commnd not found ? Sep 10 19:43:03 wtf Sep 10 19:43:16 umount not unmount Sep 10 19:43:18 opkg install umount lol Sep 10 19:43:38 yes U M O U N T Sep 10 19:43:55 ok Sep 10 19:44:03 let me dd the stuff Sep 10 19:44:10 and then get back to you if it won`t work Sep 10 19:45:04 mmmm nummy lunch Sep 10 19:45:25 freakin problems Sep 10 19:45:42 i so hoped i will finish my project in time and now have all this awkward bugs Sep 10 19:46:25 vvu why not just using dd if=/path/to/file of=/dev/mmcblkx etc ? Sep 10 19:46:47 i think i have dd on busybox right? Sep 10 19:46:57 not sure Sep 10 19:46:59 xz -cd foo.xz > /dev/mmcblkx does the same as dd Sep 10 19:47:32 and saves the extra step of manually uncompressing stuff Sep 10 19:47:56 never tried it Sep 10 19:48:18 koen so piping his image to disk why wouldnt MLO be found ? Sep 10 19:48:23 trying now with xzcat Sep 10 19:48:37 koen: with the image you gave it it`s like MLO does not get find at all Sep 10 19:48:53 i`m flashing it with xz -cd image > /dev/mmcblk0 *when no uSD is inserted* Sep 10 19:49:03 and when uSD is inserted eMMC is mapped as /dev/mmcblk1 Sep 10 19:49:41 vvu network boot / flash ? Sep 10 19:49:48 usb boot Sep 10 19:49:54 from Android device Sep 10 19:50:06 vvu, did you ever give hdparm a shot on your drive to see how fast it was ? Sep 10 19:50:13 ah nvm lol Sep 10 19:50:18 slow slow slow Sep 10 19:51:19 vvu, seriously id be interested in seeing performancedata sometime. Sep 10 19:51:40 all my own RNDIS test failed fairly badly Sep 10 19:51:45 tests* Sep 10 19:51:52 koen: my init script is http://pastebin.com/APfhesiN Sep 10 19:52:15 transfering the image to the board in .xz format takes like 5 minutes Sep 10 19:52:20 and flashing to eMMC takes like 20 minutes Sep 10 19:52:33 so overall compared to the eMMC flasher is better Sep 10 19:52:35 vvu|Log: it should work, it's a direct dump from a BBB on my desk :) Sep 10 19:53:05 now i`m trying to write it while booted from a uSD Sep 10 19:53:09 to see if it works this way Sep 10 19:53:47 vvu|Log: I've noticed a few "features" of the emmc controller Sep 10 19:53:55 like ? Sep 10 19:54:23 flashing works best if you zero out the first ~10MB (dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10) Sep 10 19:54:37 I was noticing earlier that uSD hotplug still seems to be buggy. crashed my bbb again after like a minute Sep 10 19:54:40 ah . . . Sep 10 19:54:45 and after writing it, you need to read back a few MB (e.g. 40) to flush the controller Sep 10 19:55:11 koen, seriously ? Sep 10 19:55:18 but anyway i`m doing a reboot afterwards to flushing it goes automatically i think so Sep 10 19:55:25 m_billybob: yes Sep 10 19:55:42 m_billybob: the readback thing got rid of a ton of "file missing" heisenbugs Sep 10 19:56:27 koen, wierd never heard of that before. Sep 10 19:56:46 learn somethign new every day Sep 10 19:57:08 I never reproduced it Sep 10 19:57:25 but the tester at the factory would pick out a few boards Sep 10 19:57:42 stuff like that happens when you have to do something a 100k times :) Sep 10 19:57:48 vvu, lol man you have a LOT of mountpoints ;) Sep 10 19:57:52 koen sure Sep 10 19:58:07 in the mount pastebin? Sep 10 19:58:10 yeah Sep 10 19:58:13 it`s the default Angstrom one Sep 10 19:58:19 ah Sep 10 19:58:19 booted from a fresh uSD Sep 10 19:58:26 anyway, zzzz time Sep 10 19:58:32 good night Sep 10 19:58:41 koen: okei will announce you 2morrow about the status Sep 10 19:59:00 vvu i have 10 Sep 10 19:59:18 sd emmc and a nfs root Sep 10 19:59:26 eh don`t really care Sep 10 19:59:27 many tmpfs's Sep 10 19:59:41 anyway i never stayed more than 20 mins with angstrom on :) Sep 10 19:59:49 was too busy to boot the freakin chip Sep 10 19:59:51 hehehe Sep 10 20:00:10 it`s so shitty implemented Sep 10 20:00:16 hmm ? Sep 10 20:00:22 the AM335x can do OTG but the ROM does not implement it Sep 10 20:00:38 thats pretty lame Sep 10 20:00:50 and i need to hack the android kernel to make it play well with the ROM Sep 10 20:00:58 put some angst in the rom Sep 10 20:01:46 need to get an intern position at TI and tell my problems to the engineers directly ! *a bit of WAR* Sep 10 20:02:59 also wanted to ask you guys what companies are good to intern at *soft eng but in the hw domain like TI, Cisco, Qualcomm* ?

Sep 10 20:06:56 koen did xzcat image.img.xz | dd of=/dev/mmcblk1 Sep 10 20:06:58 and same result Sep 10 20:07:16 maybe image is bad somehow ? Sep 10 20:09:29 xz -cd foo.xz > /dev/mmcblkx does the same as dd <--- is what koen said Sep 10 20:09:36 yeah Sep 10 20:10:00 is ther a checksum you cantest against ? Sep 10 20:10:17 don`t think it got corrupted while dwlding Sep 10 20:10:46 he said he dumped it off a workign bbb on his desk Sep 10 20:11:10 whats the exact eror message ? Sep 10 20:11:25 it goes into USB boot mode Sep 10 20:11:38 hmmm Sep 10 20:11:40 usb boot mode is the last boot mode tested Sep 10 20:11:49 1st is eMMC then uSD then UART Sep 10 20:11:51 then usb Sep 10 20:12:41 you have a serial debug cable i am assuming ? Sep 10 20:12:47 yup Sep 10 20:13:03 try removing he USB cable Sep 10 20:13:09 it is removed Sep 10 20:13:10 see what error it gives Sep 10 20:13:12 ah Sep 10 20:13:30 yup the image got downloaded fully before dding Sep 10 20:14:15 i dont really know much about MLO not sure why it wouldnt work Sep 10 20:14:30 boot flag was set on the first partition i saw that Sep 10 20:15:00 maybe my eMMC got screwed ?:)) Sep 10 20:15:21 i have another board, one more test with this one then switch to that one Sep 10 20:15:33 and /dev/mmcblk0p1/drivers has the am335x boneblack dtb ? Sep 10 20:15:46 it does not care Sep 10 20:15:55 i should have seen the MLO boot mesages Sep 10 20:16:01 the dtb is only for the kernel Sep 10 20:16:13 right ok Sep 10 20:16:55 can always build your own uboot / MLO -> ug Sep 10 20:16:59 at least now i can hack my pebble watch Sep 10 20:17:15 yeah but the ROM does not see even this one Sep 10 20:17:21 it would be useless to build it myself Sep 10 20:17:44 so you think the ROM is somehow "bad" ? Sep 10 20:17:54 dunno Sep 10 20:17:58 don`t think so Sep 10 20:18:02 i`m doing one more test Sep 10 20:18:08 then remove all power and see how it goes Sep 10 20:18:32 you do have everything but power disconnected while flashing yes ? Sep 10 20:18:41 yeah Sep 10 20:18:44 ethernet cable Sep 10 20:18:47 ok, jus tchecking Sep 10 20:18:57 but still won`t affect it :-? think os Sep 10 20:18:58 so Sep 10 20:19:12 it can very easily effect it Sep 10 20:19:27 if you power via USB 2.0especially Sep 10 20:19:43 i`m powering from 5v external source Sep 10 20:22:16 i have had this problem once in a while where the BBB wont boot, but power LED is the only LED that comes on. when i unplug the power, and plug it back in usually it works find afterwards. SOmetimes i have to do this more than once Sep 10 20:22:27 this does not sound like that problem though Sep 10 20:23:20 ok same result, now switched to another board Sep 10 20:28:32 How can I translate my beaglebone?
