**** BEGIN LOGGING AT Thu Jun 14 02:59:58 2012 Jun 14 03:46:42 howdy Jun 14 03:47:15 is there a more minimal distro for beaglebone available than the one that shipped with my adafruit order? Jun 14 03:47:39 snelly: rcn-ee has a minimal (90mb low memory usage) distro of ubuntu 12.4 @ rcn-ee.net Jun 14 03:47:53 oo. Jun 14 03:47:57 that might work Jun 14 03:51:23 is my rev5 Beaglebone the same thing as the BeagleBone Ax? Jun 14 04:03:53 Ax? Jun 14 04:13:08 *thanks* trelane Jun 14 04:13:14 rcn-ee's distro is sweet Jun 14 04:13:17 exactly what i wanted Jun 14 04:13:27 no firefox, no Node.js, no bullshit Jun 14 04:14:08 snelly, no worries, would you mind doing me a favor in exchange? I've had a LOT of USB WIFI dongles act flaky with that setup, would oyu mind testing any you have on hand and let me know if one works? Jun 14 04:14:12 be wery wery quiet. z java folkz will get u Jun 14 04:14:29 sure Jun 14 04:14:36 i'm actually using a USB wifi right now Jun 14 04:14:39 errr Jun 14 04:14:47 snelly, on the bone itself :) Jun 14 04:14:52 actually, it's wifi/ethernet bridge that's powered over usb Jun 14 04:15:01 i don't know if it can also act as a usb-wifi bridge Jun 14 04:15:07 i'll plug it in later and see Jun 14 04:15:13 thanks Jun 14 04:15:24 trelane, does that one Adafruit sells work? Jun 14 04:15:36 i just ordered one of them Jun 14 04:15:40 no Jun 14 04:15:48 got one sitting right here Jun 14 04:15:57 crap Jun 14 04:16:15 it looked so cute, too Jun 14 04:18:12 i need to figure out why the serial console doesn't appear to switch to the correct baudrate until after boot Jun 14 04:18:32 should be 115200 Jun 14 04:19:53 yup....for whatever reason, I get a bunch of garbled text at first Jun 14 04:20:16 then finally after a while, I get the standard console login from getty or whatever Jun 14 04:20:41 odd Jun 14 04:20:42 works fine here Jun 14 04:21:50 * heathkid|2 has several... would like them to work Jun 14 04:22:10 fix them :) Jun 14 04:22:13 the code is available Jun 14 04:22:21 hammer Jun 14 04:23:06 as is the udev and the udev scripts Jun 14 04:24:21 i'm sure i'll look at it in a bit Jun 14 04:24:30 right now i need to fix CPAN Jun 14 04:27:40 Hello everyone, I have a quick question about building angstrom for the beaglebone. I have installed all the dependencies for Open Embedded and bitbake. I am using the oebb.sh script to create a systemd-image (as these instructions say to: http://downloads.angstrom-distribution.org/demo/beaglebone/ ). When I get to openssl the build fails with the error: Can't locate find.pl in @INC (@INC contains: /usr/lib/perl5/site_perl /usr/share/perl5/si Jun 14 04:29:11 sorry for the wall of text, been at this for a little while, and keep hitting this wall Jun 14 04:29:57 man, screw angstrom, check out the rcn-ee ubuntu port :) Jun 14 04:30:21 never heard of it Jun 14 04:30:34 rather, i know there is a ubuntu version Jun 14 04:30:42 just not familar with rcn-ee Jun 14 04:30:49 http://elinux.org/BeagleBoardUbuntu#Demo_Image Jun 14 04:30:56 i just found out about it tonight Jun 14 04:31:01 i'm so much happier with this Jun 14 04:31:11 Hi guys, I want to port ubuntu on beaglebone. Where do I get the image. Can I use ARM image on Ubuntu.com. It have many flavour. Which one should I use. Jun 14 04:31:22 if you're familiar with ubuntu, you'll like it better Jun 14 04:31:23 moorejohn: http://elinux.org/BeagleBoardUbuntu#Demo_Image Jun 14 04:31:54 i'm ok-ish with ubuntu. been a little while, but I'll learn fairly quickly Jun 14 04:31:57 thank you Jun 14 04:32:01 Hi snelly, it is the same as image from ubuntu.com Jun 14 04:32:05 I will give that a go Jun 14 04:32:11 moorejohn: i have no idea Jun 14 04:32:21 good bye angstrom! Jun 14 04:32:25 moorejohn: i just started using it tonight and i'm happy so far Jun 14 04:32:29 hello ubuntu! Jun 14 04:32:48 sorry snelly, is it the same version as from ubuntu.com Jun 14 04:33:07 if I can get my weather station working on my beaglebone, i'm going to be super happy Jun 14 04:33:29 snelly: what weather station do you have? Jun 14 04:34:10 moorejohn: the download link on the page snelly gave us points to the main ubuntu site, so yes, it is the same Jun 14 04:34:18 or, should be Jun 14 04:34:27 downloading now, so we shall see wht happens Jun 14 04:34:39 oo I see thank a lot Jun 14 04:34:48 I run a Davis Vantage Pro2 with UV & Solar plus an additional station for extra temp Jun 14 04:34:55 heathkid: I have an old Davis Instruments Weather Monitor II Jun 14 04:34:58 solar, wireless Jun 14 04:35:03 those are nice Jun 14 04:35:24 i wrote some software for it in perl and python Jun 14 04:35:40 heathkid: awesome Jun 14 04:35:59 moorejohn: the one thing, I believe we want the headless versions, unless you have one of the dvi adapters Jun 14 04:36:19 snelly: most people don't realize running a weather station takes a LOT of time... Jun 14 04:36:39 keeping it clean, software updates, etc... Jun 14 04:36:46 how are you guys interfacing the beaglebone to the weather station? Jun 14 04:36:55 I'm not Jun 14 04:36:58 heathkid: this one runs itself Jun 14 04:37:06 magyarm1: USB to serial adapter i hope Jun 14 04:37:08 all the software I run in windows Jun 14 04:37:11 and it sucks Jun 14 04:37:29 heathkid: I have a little daemon written in perl that collects the current weather from the station over RS-232 Jun 14 04:37:34 Hi magyarm1, waht you mean dvi adapters Jun 14 04:37:34 then it stores it in Redis Jun 14 04:37:39 nice snelly! Jun 14 04:37:58 once it's in Redis, I have a little python-based server that serves it up to a Mac OS X app that I have Jun 14 04:38:08 the little python server can also output RRD graphs Jun 14 04:38:24 so here on my Mac, I have live weather on my desktop that updates every 5 seconds or so Jun 14 04:39:05 sounds better than VWS Jun 14 04:39:13 oh def. Jun 14 04:42:10 USE HIS THING Jun 14 04:42:20 the bucket of suck that is heathkid's weather software makes baby penguins cry :( Jun 14 04:42:23 heathkid: https://dl.dropbox.com/u/16837290/WeatherStation/remoteweather-1.0.tar.gz Jun 14 04:42:33 so be aware, that code is totally undocumented Jun 14 04:42:42 you'll need to set up Redis first Jun 14 04:42:47 * trelane beats snelly with a fresh fish for not documenting Jun 14 04:42:47 and then install some python and perl modules Jun 14 04:42:53 and then set up RRD files Jun 14 04:43:02 trelane: lol, i wrote this like 10 years ago :P Jun 14 04:43:53 oh, here's the little Mac OS X Dashboard app for it Jun 14 04:43:53 https://dl.dropbox.com/u/16837290/WeatherStation/WeatherStation.zip Jun 14 04:43:53 !!! Jun 14 04:44:08 at one time, it was nicely documented on my remoteweather.com site Jun 14 04:44:14 snelly, is there a good howto on RRD? Every bit of RRDtool's documentation sucks at what an RRD file should look like internally Jun 14 04:44:26 and then the ancient OpenBSD box that ran that site crashed Jun 14 04:44:54 well, from a user perspective, you're just using rrdcreate Jun 14 04:45:12 it's not too bad Jun 14 04:45:17 you basically define some datasources Jun 14 04:45:37 and define the RRA's (the archives) where those datasources are stored Jun 14 04:46:40 http://oss.oetiker.ch/rrdtool/tut/index.en.html Jun 14 04:46:46 the first one is the best Jun 14 04:46:54 that's how i learned back in the day Jun 14 04:53:15 trelane: taking notes? Jun 14 04:53:30 heathkid, yep Jun 14 04:53:37 awesome! Jun 14 04:53:51 snelly, my problem is what the datasource should look like Jun 14 04:53:51 it'd be nice to get this weather station off windows Jun 14 04:54:06 I have to get some sleep... Jun 14 04:54:18 goodnight and talk to you all tomorrow... Jun 14 05:03:40 trelane: the datasource definition? like when you create the RRD? Jun 14 05:03:52 no what the RRD should look like Jun 14 05:03:54 or what the data should look like once the RRD is created and you're feeding it data Jun 14 05:03:59 the bit I don't understand is from the input source to the RRD Jun 14 05:04:02 ah Jun 14 05:04:16 I'm taking data from an analog pin on the bone Jun 14 05:04:18 MAGIC HAPPENS Jun 14 05:04:23 the data apperas in rrdtool Jun 14 05:04:30 the middle bit is where I'm screwed Jun 14 05:04:39 ok, so the RRD file (the .rrd) is managed by rrdtool. so you use rrdupdate to update the rrd file Jun 14 05:04:48 you basically say something like this: Jun 14 05:05:13 rrdupdate beagleboard.rrd 0.8 4.12 etc Jun 14 05:05:25 check out that code i pasted earlier Jun 14 05:05:43 and see how the python code updates my weather rrd with the latest temperature, wind, etc. measurements Jun 14 05:05:56 ok Jun 14 05:06:08 so I'm just stuffing the variables into rrdupdate and it takes care of the magic for me Jun 14 05:06:13 typically you'll use Perl, Python, C, etc. to interface between your data gatherer and rrdtool Jun 14 05:06:26 you can call rrdupdate on the commandline or use one of the APIs to call it Jun 14 05:06:43 exactly. you just pass rrdupdate the data and it handles the rest Jun 14 05:06:50 then rrdgraph makes the pictures Jun 14 05:07:38 snelly well, as I'm using bash, I'll just call it from the command line :) Jun 14 05:07:45 are you reading off the beagleboard's GPIO pins or somethin? Jun 14 05:07:49 yeah Jun 14 05:07:54 how does one do that? Jun 14 05:08:07 they're all exported to in /sys Jun 14 05:08:12 ah, ok Jun 14 05:08:27 shit, i'd love to use my beagleboard to control some stuff around here Jun 14 05:08:33 let me throw you up some code Jun 14 05:08:54 i'm sure there's a way to put some 1-wire devices on the BB somehow Jun 14 05:10:27 http://pastebin.com/Karu2zdt Jun 14 05:10:31 that's a pump timer for... something Jun 14 05:10:55 lol Jun 14 05:10:57 anyway there's 3 "chips" on the beaglebone 24 GPIO's each so it's chipX24+pin Jun 14 05:10:57 ;-) Jun 14 05:11:07 so I'm flipping pin 7 Jun 14 05:11:16 err GPIO 7 Jun 14 05:11:18 chip 0 pin 7 Jun 14 05:11:23 it's below the AIN's on P9 Jun 14 05:11:53 dang, the /dev abstraction makes it easy Jun 14 05:11:58 you have to tell the driver to turn it on Jun 14 05:12:08 and then it creates a subfolder with various parameters of the device Jun 14 05:12:14 you'll see that that script manipulates several of those Jun 14 05:12:17 that's too easy Jun 14 05:12:47 everything in linux is a file Jun 14 05:12:49 makes life easy Jun 14 05:13:44 man, i wish that adafruit wireless thing worked Jun 14 05:14:00 it looked like the ticket when i ordered it Jun 14 05:15:01 gotta get NFS set up now so I have some place to store these RRDs Jun 14 05:15:11 i don't trust these SD cards Jun 14 05:15:43 ok, question for y'all Jun 14 05:16:00 what's the linux implementation of Bonjour called? Jun 14 05:16:15 zeroconf, etc Jun 14 05:16:30 no idea Jun 14 05:16:38 never used it Jun 14 05:16:48 it's pretty handy Jun 14 05:17:23 ok, here we go Jun 14 05:17:25 avahi Jun 14 05:18:17 trelane: ever played with OpenBSD's GPIO implementaiton? Jun 14 05:18:32 no, I am not much of a BSD fan actually Jun 14 05:18:41 always wondered what avahi did Jun 14 05:18:43 just ignored it Jun 14 05:18:52 trelane: you know about zeroconf? Jun 14 05:19:02 basically does automatic hostname resolution Jun 14 05:19:13 so i bought a new HP LaserJet 500 color today Jun 14 05:19:25 and it announces itself via zeroconf Jun 14 05:19:43 so i can now do: % ping lanai.local Jun 14 05:19:48 (lanai is the name of the printer) Jun 14 05:20:02 don't have to worry about setting up DNS locally Jun 14 05:20:22 ssh beaglebone.local, etc Jun 14 05:20:58 ooh I just use dd-wrt for that Jun 14 05:22:31 i guess i like it because it's distributed. no need for any central authority Jun 14 05:22:44 and every consume network device you buy these days can announce itself Jun 14 05:22:47 hello. Can anybody can recommend me suitable solution. I do some arm optimizations (asm, neon) and I would like to see instruction level profiling info. Any good advice on that? Jun 14 05:24:30 I used profiler that comes with RVDS from arm but it has some bugs that I have no idea how to avoid, so I'm thinking to get a beagleboard and use it for development. Jun 14 05:26:36 wish i knew randomguy123 Jun 14 05:26:42 i'm not that low-level :/ Jun 14 05:28:02 I see here and there that many people use beagleboard for testing optimized code. So I was wondering is there are some tools or it's a for(int =0; i<1000000; ++i){ run_test(); } Jun 14 05:28:46 out of curiousity, what are you writing? Jun 14 05:28:54 basically, profiler from RVDS shows disasm of the c code and how many cycles each instruction takes Jun 14 05:29:08 i'm working with math and audio-video codecs. Jun 14 05:29:11 dsp processing etc. Jun 14 05:29:19 ah, cool Jun 14 05:29:25 so, I need to optimize algorithms here and there. Jun 14 05:29:51 the proliferation of cheap SBCs that can do HD video is just amazing to me Jun 14 05:30:13 I decided to dump that RVDS for a simple reason: I can't do unaligned memory access with this pile of bugs. Jun 14 05:32:04 isn't that lauterbach stuff also used for that? (yes i know their pricing) Jun 14 05:33:39 damn, the only thing keeping me from getting my weather station working on my beaglebone tonight is lack of a freaking power strip Jun 14 05:34:37 has anyone here configured one of those OLEDs on breakout board as serial terminal under Linux? Jun 14 05:34:51 they support SPI and two baud speeds Jun 14 05:35:00 RITRedbeard: link? Jun 14 05:35:46 RITRedbeard: i've never done it but it couldn't be too hard Jun 14 05:36:11 http://www.adafruit.com/products/684 and http://www.sparkfun.com/products/8538 Jun 14 05:36:31 like to make it the main display? display boot, init, all that stuff? Jun 14 05:37:32 here's another vendor's SPI-controlled LED Jun 14 05:37:33 http://lxr.free-electrons.com/source/drivers/leds/leds-dac124s085.c Jun 14 05:37:40 check that out Jun 14 05:37:56 they also support serial too Jun 14 05:38:04 I figure doing serial first would be easier Jun 14 05:38:13 oh, definitely Jun 14 05:38:29 with that, you basically set it up in getty or whatever the cool kids are using these days Jun 14 05:38:50 https://help.ubuntu.com/community/SerialConsoleHowto Jun 14 05:38:52 since these embedded systems don't have grub.. you'd need to read the documentation on how to perhaps select in there Jun 14 05:39:16 but: make sure that you're driving it over a TTL to RS232 convertor Jun 14 05:39:20 or you will fry your LCD Jun 14 05:40:02 does linux/unix console expect also keyboard input? I just care about output Jun 14 05:40:18 nah Jun 14 05:40:27 it can be output only if you want Jun 14 05:41:09 neat little module Jun 14 05:41:31 I'm interested in head mounted display technology Jun 14 05:41:39 heh Jun 14 05:41:40 I figured I could use one of those and make a ghetto monocular Jun 14 05:41:47 I can do everything in 80x25 anyway Jun 14 05:41:51 mostly Jun 14 05:42:06 80x25 and gnu screen Jun 14 05:42:08 :) Jun 14 05:42:36 i haven't messed with a serial console since the 90's Jun 14 05:42:46 well, excluding embedded stuff Jun 14 05:43:00 yeah I was going to buy a beaglebone Jun 14 05:43:12 but since I'm not good with electronics and could get an affordable interface Jun 14 05:43:22 I got one of those "rikomagic" m802s Jun 14 05:43:30 Cortex based, Mali 400 GPU Jun 14 05:43:40 Allwinner A10 is the SoC name I think Jun 14 05:43:51 back in the day (like 1994), i had a 486 machine set up in my dorm with a couple of DEC serial consoles Jun 14 05:43:52 and a Motorola Lapdock for $70! good price Jun 14 05:43:58 heh Jun 14 05:49:13 I was aiming for a Pi but the waiting game was kinda lame. Jun 14 05:49:24 I'll pick up a bone once I've done some work on this platform Jun 14 07:27:55 yo Jun 14 07:28:40 I am connecting my beaglebone, which already has the installed image of angstrom, to my computer but it does not show up as a USB connection Jun 14 07:29:03 In fact, nothing happens at all, other than the USER0 light flashes at rate of 2 Hhz. Jun 14 07:29:44 I dont know what that means. And I cannot see the dog image coming into my laptop, nor can I ssh to the board. Yesterday I was updating my angstrom distro with the "opkg upgrade" command, but after 30 minutes I did control-C to stop Jun 14 07:30:03 does anyone know what the problem might be? Jun 14 09:41:43 dm8tbr: ping Jun 14 09:42:00 av500: boingboing Jun 14 09:42:18 unping, f'up pm Jun 14 10:08:41 Is it possible to use graphical user interface for the angstrom-Cloud9-IDE-GNOME-eglibc-ipk-* images in beagle bone? Jun 14 10:10:37 I thought cloud9 is a gui Jun 14 10:10:58 I thought it is a cloud Jun 14 10:11:08 a clouded gui Jun 14 10:11:49 ok thank you Jun 14 10:12:20 angs: you should be able to access cloud9 from your browser Jun 14 10:14:19 clouds obscuring the GUI? Jun 14 10:15:44 blearily GUIs Jun 14 10:34:05 Can I use BeagleBone to commercial projects? Jun 14 10:34:40 sure Jun 14 10:51:55 Saulanko: 1) no pm please Jun 14 10:52:05 2) if you need large numbers, talk to circuitco Jun 14 10:52:13 if you need a few, just buy them Jun 14 10:55:05 av500: Ok, thanks for the advice, need to buy first few of them Jun 14 11:18:54 hey, I have archlinux-arm installed on my beaglebone. I'm trying to use "cpupower", but it's complaining: "no or unknown cpufreq driver is active on this CPU".Any ideas to get this working? Jun 14 11:26:05 customize your kernel Jun 14 11:29:42 aholler: I found the linux-omap package which seems to provide the driver. Although it complains about /boot/uImage existing already in filesystem. I remember needing to create this so that my system would boot properly. What would happen if this get's overridden? Jun 14 11:32:06 bone != omap Jun 14 11:34:01 aholler: okay, I figured because this guy uses cpufreq on his beaglebone and the command output states that the omap driver was used: http://beaglebone.cameon.net/home/set-cpu-speed Jun 14 11:35:03 use that kernel: https://github.com/koenkooi/linux/tree/linux-ti33x-psp-3.2.18-r12i+gitr720e07b4c1f687b61b147b31c698cb6816d72f01 Jun 14 11:36:25 aholler: okay thx Jun 14 11:56:39 http://liliputing.com/2012/06/how-to-run-ubuntu-linux-on-the-mk802-74-pc-on-a-stick.html Jun 14 11:57:03 looks better than Pi Jun 14 11:57:25 those kind of minipc/A8 are sold in volume at $40 on the street Jun 14 12:23:00 Is there any documents/information how to integrate cinterion modules for beaglebone? Jun 14 13:19:22 Sakari: what's that module? M2M, what interface is it Jun 14 13:20:23 i c, usb/serial/i2c/spi... Jun 14 13:38:43 hello guys Jun 14 14:30:38 I cannot boot from narcissius image. It says file not found /boot/uImage. But uImage file is present in /boot. Can some one suggest a fix for this Jun 14 14:32:47 pastebin full boot log Jun 14 14:32:54 pastebin the content of your boot partition Jun 14 14:34:14 http://pastebin.com/RDLM6NaF Jun 14 14:35:23 setenv bootcmd 'mmc init;fatload mmc 0 80300000 uImage.bin;bootm 80300000' Jun 14 14:35:30 this is uEnv.txt Jun 14 14:36:19 where does /boot appear in your uEnv.txt? Jun 14 14:36:47 why you have that setenv in uEnv.txt? Jun 14 14:37:02 uEnv.txt != boot.cmd Jun 14 14:38:02 I saw this fix in a forum. I will paste the lnk Jun 14 14:38:25 then ask in that forum Jun 14 14:38:40 whatever that should fix Jun 14 14:39:12 sorry, I dont have much idea of how this works Jun 14 14:39:51 I just copied it Jun 14 14:41:45 andit is totally wrong. try deleting uEnv.txt Jun 14 14:42:32 ok Jun 14 14:43:19 It gives the same error Jun 14 14:43:45 file not found /boot/uImage Jun 14 14:44:04 so do what av500 said and paste the contents of your boot partition. Jun 14 14:45:49 but your problem seems to be that you are missing the partition which contains the rootfs (and boot/uImage) Jun 14 14:45:57 It contains "MLO u-boot.bin uImage uImage.bin" Jun 14 14:47:18 so where do you see /boot? Jun 14 14:47:38 its in ext4 partition of memory card Jun 14 14:47:50 other partition Jun 14 14:51:36 Would you like to see the contents of /boot in ext4 partition? Jun 14 14:53:23 not really, but fdisk -l /dev/mmcFoo could make sense. have a look at the partiton number it tries to load uImage from Jun 14 14:54:09 also, pastebin a full boot log Jun 14 14:57:39 http://pastebin.com/zWMtkKci Jun 14 14:59:05 I tried fdisk -l /dev/mmcbkp2. output is this http://pastebin.com/tcrkV5AW Jun 14 15:03:31 try without 2[D Jun 14 15:03:41 s/[D// Jun 14 15:04:11 both the partitions? Jun 14 15:04:43 a partiton doesn't have a partition table, so using fdisk on a partition doesn't make much sense Jun 14 15:05:50 ok Jun 14 15:08:36 hi, can anybody point to a working u-boot.bin for revision C4 Beagleboard? I have a keyboard connected and it isnt even detected Jun 14 15:09:07 the usb-port on the c4 only supports high-speed Jun 14 15:09:29 => you need hub for your keyboard Jun 14 15:10:22 aholler: oh then it is not a uboot.bon problem? how could i test? do i forcibly need a powered hub for anything to work? Jun 14 15:11:06 for a keyboard the hub doesn't need to be powered Jun 14 15:12:31 uhm okay i have a hub but i lost the ac adaptor, i'll try just now Jun 14 15:13:13 this is fdisk output Jun 14 15:13:15 http://pastebin.com/aW50905g Jun 14 15:15:18 wow, extended Jun 14 15:15:31 prohitkpr: have a close look at the numbers Jun 14 15:15:33 does uboot even support that? Jun 14 15:15:39 yes Jun 14 15:16:02 do I have to reformat it? Jun 14 15:16:37 no, a correct uEnv.txt would be enough Jun 14 15:17:49 aholler: oh! cool! Jun 14 15:18:40 try a line with 'mmcdev=0:5' in uEnv.txt Jun 14 15:19:42 (without the quotes) Jun 14 15:19:58 ok Jun 14 15:22:05 you might another line 'mmcroot=/dev/mmcblk0p5 rw' Jun 14 15:22:18 and you need to fix fstab Jun 14 15:22:47 as you are using partition number 5 and not 2 Jun 14 15:22:50 forroot Jun 14 15:24:01 ok Jun 14 15:24:13 so removing the extented partition and using a second primary might be easier Jun 14 15:25:29 I will do that Jun 14 15:25:48 aholler: Thanks! Jun 14 15:26:19 aholler: yes!! it was detected but only if it was connected at boot, is it correct ? Jun 14 15:27:20 I don't know if angstrom supports hotplugging keyboards Jun 14 15:28:40 anyway at least it works now Jun 14 15:31:28 it worked, but the hub has to be connected at boot Jun 14 15:31:44 once it booted it has hotplugging of mice and keyboards Jun 14 15:32:33 sounds wrong, but usb and omap is always an adventure Jun 14 15:34:29 phone builders primarily use usb for charging ;) Jun 14 15:34:55 aholler, a gpmc-connected usb cape could fix all of this on beaglebone ;) Jun 14 15:35:17 mdp: just connect a Tegra3 over UART... Jun 14 15:35:18 hi everyone: i recently imaged a sd card for beagleboard xm with rcn's setup-sdcard.sh script for ubuntu precise: however, when i boot with this SD card, i get this weird error: http://pastebin.com/MDwwVdgD . Any suggestions? Jun 14 15:35:44 av500, +1 Jun 14 15:35:57 or any just any other arm device not from ** Jun 14 15:36:07 ;) Jun 14 15:36:22 * mdp bows out of this discussion until after work hours ;) Jun 14 15:37:58 damned qt recipes bugged Jun 14 15:38:12 i'm try a qt embedded build from another site Jun 14 15:38:23 stuk_gen: are you trying Qt5 ? Jun 14 15:38:25 and work great with qt creator Jun 14 15:38:41 Desert: no, qt4.8.0 embedded in qt creator Jun 14 15:38:52 Desert: from angrstrom recipes Jun 14 15:39:05 Desert: but the mkspec is all bugged Jun 14 15:39:10 i know Jun 14 15:39:15 i gave up Jun 14 15:39:20 Desert: if you use qmake2 maybe can work Jun 14 15:39:31 Desert: but if you want add to qt creator is hell! Jun 14 15:39:52 well somehow, cant remember i got a binary build Jun 14 15:40:21 Desert: today i try a qt commercial build with have qt embedded Jun 14 15:40:21 i configured creator to automatically upload binaries Jun 14 15:40:25 and ran from there Jun 14 15:40:33 via ssh Jun 14 15:40:39 worked perfectly Jun 14 15:40:39 Desert: and its work well, the only limit is having support for QOpenGl Jun 14 15:40:49 yes, i need opengl too Jun 14 15:40:56 Desert: this is done by qt creator commercial :P Jun 14 15:41:05 Desert: and do the same you doing Jun 14 15:41:14 so, gl is not available for opensource qt ? Jun 14 15:41:28 i remember it was indeed possible Jun 14 15:42:17 hi beagleboarders Jun 14 15:43:44 hi Jun 14 15:44:24 i just got my beaglebone - really impressed Jun 14 15:44:25 * prpplague read that has "beaglehoarders" Jun 14 15:44:49 we are all beagleboarders and beagleboners right? Jun 14 15:44:57 :) Jun 14 15:45:05 it's a grave here, yes Jun 14 15:46:09 i would like to build a custom cape for the bone Jun 14 15:46:29 something with audio on it Jun 14 15:46:58 do you guys think i should look at what audio chip is on the beagleboardxm and try to work around it? Jun 14 15:47:39 no Jun 14 15:48:11 okay... Jun 14 15:51:40 can you point me in the righ direction of a certian chip / bus / protocol perhaps? Jun 14 15:53:21 maybe someone else, I don't have any experience with that. I just know that the xm uses a pmic for sound and I assume you don't want that. Jun 14 15:54:13 power mgmt chip w/audio ??? Jun 14 15:56:29 yes, if I've read that correctly. I never played with it. Jun 14 15:56:54 gopher2x: yes Jun 14 15:56:58 the pmic has a codec Jun 14 15:57:04 its shit, but OK for a cell phone Jun 14 15:57:18 use some wolfson or crystal codec Jun 14 16:00:26 humm ok . . . gotcha Jun 14 16:14:33 why should i use am335x if it's like $20 for 1ku? Jun 14 16:14:54 industrial design is hard to get the 1M units to reach $5 price point Jun 14 16:15:46 then buy something else for $5 Jun 14 16:16:44 i'm just thinking TI is pushing the limit of sells pitch Jun 14 16:17:38 industrial usually includes support Jun 14 16:18:18 and documentation Jun 14 16:20:02 xxiao: what, sales people pushing the limits? unheard of... Jun 14 16:20:09 report them to the BBB Jun 14 16:24:51 av500: i was told by other arm chip vendors that AM335x's $5 pricing could kill them, but when I look at TI's distributors the price is far from $5, not even close Jun 14 16:25:43 then in the fine prints it's like $5 for 1M unit, normally i would expect the price is for 1ku Jun 14 16:26:19 av500: what's your thought on those $40-$70 minipc thing? Jun 14 16:26:33 A8 + hdmi + usb that is Jun 14 16:28:14 you are doing industrial design without having documentation? Jun 14 16:28:31 * gopher2x likes the new minipc from china Jun 14 16:29:26 hi Jun 14 16:29:31 I wouldn't even be sure that there is a word for errata in chinese ;) Jun 14 16:29:54 aholler: even erata are stolen from other SoC makers :) Jun 14 16:30:02 xxiao: my thought, dunno Jun 14 16:30:11 depends on what you want to do with them Jun 14 16:30:19 they run android like any other 1ghz A8 Jun 14 16:30:27 and suck at ubuntu like any other 1ghz A8 Jun 14 16:30:40 ubuntu is said to be slow...time to load angstrom there Jun 14 16:30:57 I mean, its 1GHZ where people have 4x3ghz as desktops Jun 14 16:30:59 or laptops Jun 14 16:31:23 maybe good for kiosk Jun 14 16:31:34 xxiao: sure Jun 14 16:31:36 * aholler is still waiting for some ivy-laptops to reach his country :( Jun 14 16:31:39 for dedicated application Jun 14 16:31:41 normally A8 from china is strong in decoding Jun 14 16:31:46 its hardware Jun 14 16:31:51 even arm9/arm11 are good at that Jun 14 16:31:59 yes Jun 14 16:32:05 hey guys my beaglebone is heating very fast. is this normal?!? Jun 14 16:32:10 they all do gazillions of triangles and 1080p Jun 14 16:32:25 so they all run xbmc like a champ Jun 14 16:32:30 shinobi_: what are you doing exactly? Jun 14 16:32:34 but them, the xbox did that 10ys ago... Jun 14 16:32:49 just bought it Jun 14 16:33:09 nothing special Jun 14 16:33:11 take it out of the oven then Jun 14 16:33:21 * xxiao is chatting with a minipc reseller in HK right now Jun 14 16:33:22 :D Jun 14 16:34:34 aholler: its giving same error. uEnv.txt has only this line 'mmcroot=/dev/mmcblk0p2 rw' Jun 14 16:34:58 prohitkpr: you don't need that line Jun 14 16:35:13 again, paste full boot log ;) Jun 14 16:35:37 aholler: hey, thats MY line Jun 14 16:35:47 but its under CC Jun 14 16:36:05 freedombox...is it a vpn thing? Jun 14 16:37:04 av500: sorry this is boot log Jun 14 16:37:05 http://pastebin.com/vZ6W1MiK Jun 14 16:37:58 * av500 goes off-shift Jun 14 16:38:12 prohitkpr: and fdisk -l now shows you a partition with numer 2? Jun 14 16:39:20 this is fdisk output Jun 14 16:39:22 http://pastebin.com/QqdcnNTg Jun 14 16:40:52 now explore /boot in that partition. btw, what fs do you've used for the linux-partition? Jun 14 16:41:18 Angstrom Jun 14 16:41:55 anyway, just stop u-boot and have a look at with printenv end explore your mmc with fatls and ext2ls Jun 14 16:42:23 ok Jun 14 16:42:24 or use a preformatted image Jun 14 16:43:00 what linux distributions are officially supported for beaglebone? Jun 14 16:43:12 none Jun 14 16:43:20 they sell hw, no sw Jun 14 16:43:53 I guess ubuntu supports beagleboard, no? Jun 14 16:44:20 I am working on aproject Jun 14 16:44:48 I already had one working image on SD card Jun 14 16:45:06 what distribution do you have? Jun 14 16:45:30 2012.06 Jun 14 16:46:07 angstrom distribution? Jun 14 16:46:08 I need opencv and beagleboard dsp acceleration examples Jun 14 16:47:12 angs: angstrom-2012.06 I think Jun 14 16:48:41 I could develop application for arm. I need to compare its performance with the performance I would get on optimizing it with DSP processor Jun 14 16:49:19 so I am trying the narcissius image which has these built in demo examples Jun 14 16:56:27 angs: ubuntu supports beagleboard. I could run ubuntu on my beagleboard Jun 14 16:58:34 I also used ubuntu and debian dist that beaglebone's webpage links. however, neither debian nor ubuntu officially supports beaglebone and I had kernell problems, so I can not get any help from them Jun 14 16:58:45 I will try archlinux Jun 14 17:00:01 angs: I could not downnload any packages. I modified sources.list. setup http_proxy env variable Jun 14 17:00:52 I shifted to angstrom and could get opencv and other packages working. but I could not optimize for dsp Jun 14 17:35:51 while booting it says wrong image format Jun 14 17:45:47 I never used beagleboard and dsp Jun 14 17:46:31 I decided to install fedora Jun 14 18:25:41 hello :) I am new to the concept, I want to ask, which is the maximum sampling rate of the embedded ADC ? Jun 14 18:27:39 read the AM335x manual? Jun 14 18:28:00 ok lets see Jun 14 18:32:13 hi all Jun 14 18:32:40 I'm having issues with booting my board and I'm noticing that the u-boot mainline source when built creates an MLO Jun 14 18:35:11 ahm I see that adc clock is at 3Mhz so you have 200kSPS....? so you can see maximum frequency at 100khz? Jun 14 18:38:54 mranostay, that's just silliness Jun 14 18:57:02 actually i was wondering about the beagleaboard processor omap3530 Jun 14 18:58:16 but although it has a dsp processor i cant find analog in channels Jun 14 19:06:20 Now this is weird Jun 14 19:06:30 formatting a new SD card with ext3 results in some stupidly high system load Jun 14 19:51:06 Sh0rtWave: new SD cards require one to first wake the silicon Jun 14 19:54:08 any news rumors about TI releasing armhf sgx and dsp drivers? Jun 14 19:55:15 * mdp reads that as ARM High Frequency! for some reason… Jun 14 20:41:02 what image of beaglebone works fine with rtl8192cu chipset? Jun 14 20:42:05 none Jun 14 20:42:09 it's a usb device Jun 14 20:42:23 go bug TI about the crappy usb support Jun 14 20:44:31 so it does not matter what distribution I use in beaglebone, right? Jun 14 20:48:07 would it be possible to fix it by software or would I need to wait next version of beaglebone A6/7 to use usb wifi stick? Jun 14 20:48:33 22:42 < koen> go bug TI about the crappy usb support Jun 14 20:54:37 I bought 5 beaglebones to do a wlan project. what would be the alternative way for beaglebone to have wifi ability? Jun 14 20:55:27 there a hundred different ways Jun 14 20:55:56 I would appreciate if you can explain the easiest way Jun 14 20:56:32 is there any component like ethernet to wifi converter? Jun 14 20:57:09 angs: hehe easiest is relative to your skills, what is easy for me, probably isn't easy for you Jun 14 20:58:52 does usb wifi port work fine in beagleboard? Jun 14 21:23:30 on SD or usb-dongle storage devices, i saw the device is mounted as read-only sometimes Jun 14 21:23:59 even though i mounted them as read/write first, i could force it to ignore any errors to remain as read/write Jun 14 21:24:12 but...what is causing this failure that leads to read-only? Jun 14 21:25:00 rw,relatime,errors=continue,barrier=0,data=ordered for ext3 Jun 14 21:26:15 hmm...looks like i need give barrier=1 instead, otherwise the fs could be corrupted indeed Jun 14 21:26:29 performance will suffer but at least fs will be intact Jun 14 21:37:20 my work performance is suffering... Off tomorrow though :) Jun 14 21:37:37 and hopefully I'll be intact Jun 14 21:53:05 All the farads escaped from my heat pump fan capacitor. Jun 14 21:53:30 I was able to rounds up some fresh farads, stuff them into the unit and all is better Jun 14 21:53:47 s/rounds/round Jun 14 23:19:25 I'm writing a driver that interfaces a UART chip to a OMAP via the SPI interface Jun 14 23:19:41 problem is that the UART has spinlocks and the McSPI driver sleeps Jun 14 23:19:47 this blows up and deadlocks Jun 14 23:20:02 has anyone looked at using the syncing with the DSS interrupt on the 37xx chip from userland? Jun 14 23:20:04 does anyone have any ideas on how to approach fixing this? It would seem that the mcspi driver needs to not sleep Jun 14 23:20:19 toofar: workqueue Jun 14 23:21:12 ds2: but then I'd have to sleep waiting for an answer from the workqueue like the mcspi driver does already with wait_for_completion and complete() Jun 14 23:21:40 eh? Jun 14 23:21:58 what is the problem there? Jun 14 23:22:17 I can't sleep while holding a spinlock Jun 14 23:22:21 that's the entire problem Jun 14 23:22:32 then design it out Jun 14 23:22:43 there are SPI based UART drivers around Jun 14 23:22:59 Of the McSPI peripheral? Jun 14 23:23:03 that's the only solution I see Jun 14 23:23:12 rewriting tty + uart is not feasible Jun 14 23:23:57 why do you care what the underlying SPI hardware is? Jun 14 23:24:04 because it sleeps Jun 14 23:24:17 if you code cares, then it is not done right Jun 14 23:24:19 and the higher level software (uart + tty) holds a spin lock Jun 14 23:24:34 you're never supposed to sleep in a spin lock Jun 14 23:24:52 look around, there are drivers written for SPI based UARTs Jun 14 23:25:16 and I'm betting the low level spi hw layer those are used with don't sleep like McSPI does Jun 14 23:25:33 stop looking underneath the covers, that is entirely the wrong way of going about it Jun 14 23:26:51 The moment I turn on CONFIG_DEBUG_SPINLOCK_SLEEP what's under the covers becomes the focus of my problem Jun 14 23:27:31 calling spi_sync() with the mcspi implementation sleeps Jun 14 23:27:49 calling spi_async() doesn't sleep, but then I need to spin there waiting for an answer Jun 14 23:27:58 if I spin after spi_async() then the workqueue doesn't run Jun 14 23:30:13 I think you have it wrong, there are working drivers that make no assumptions on the lower layers Jun 14 23:53:37 ds2: The max3107 driver is similar Jun 14 23:53:43 and it calls spi_sync() just the same Jun 14 23:54:01 can't determine what underlying spi driver the original author was workign with Jun 14 23:54:35 what will be the next board? Jun 15 01:35:38 Hello there #beagle. I've been trying for about an hour to check for a problem with a beagleboard, rev C4. After connecting to a USB power source which should be sufficient (tried : laptop with high-power ports available; wallwart to USB) on the small mini-AB port, all I get is the power LED comes on and the PMU STAT LED blinks every 2 seconds or so. Jun 15 01:52:16 don't use usb otg to power Jun 15 01:53:39 thurbad: there didn't seem to be that big of a bug about it though. So, you recommend the 5V wallwart? Any idea what causes this? It's probably not the linux kernel USB handling bug, is it? Jun 15 01:55:35 hard to tell but if only the pmu stat light comes on sporadically it's probably insufficient power Jun 15 01:56:53 power led is on though. Jun 15 01:57:02 considering it's on the rail though, I kind of expect that Jun 15 01:59:19 what are you calling the pmu led then? Jun 15 02:00:26 there's a PWR led Jun 15 02:00:33 which lights up full blast Jun 15 02:00:56 aside the OTG port Jun 15 02:01:51 the one between the 5V port and the RS-232 is blinking, and has "PMU STAT" Jun 15 02:01:53 on it Jun 15 02:03:39 the PWR one, for preciseness, is right aside J2, close to the two audio jacks Jun 15 02:17:51 any recommendations on power supplies for the beagleboard xM. i have 6 and i'm going to use them in a course i'm teaching, but none of my 5V power supplies seem to have enough juice. Jun 15 02:24:50 blueness: they are availabe in a wide range of places Jun 15 02:24:56 blueness: where are you located? Jun 15 02:33:02 buffalo ny Jun 15 02:33:16 i just need to know a good voltage and amp Jun 15 02:34:08 eg i'v got a 5V 2.4V dve and it doesn't seem to boot the nick card Jun 15 02:34:18 but my 5V 2.5A does Jun 15 02:34:26 oops i mean 2.4A not 2.4V Jun 15 02:35:14 what nick card are you referring to? Jun 15 02:36:07 the onboard Jun 15 02:36:23 intersting Jun 15 02:36:37 normally a 2A ps for beagle-xm is fine Jun 15 02:36:55 but it also depends on what usb devices and expansion devices you are using Jun 15 02:37:03 what usb devices are you using? Jun 15 02:37:21 none Jun 15 02:37:44 something sounds a little out of place then Jun 15 02:38:04 you might want to check the actual voltrage of the 2.4A wall-wart Jun 15 02:38:14 i suspect it might be lower than the tolerance Jun 15 02:38:29 yeah i'm getting that sense too Jun 15 02:38:41 what's the normal operating voltage range? **** ENDING LOGGING AT Fri Jun 15 02:59:59 2012
