Jun 15 03:20:03 i can't figure out what gets compiled when Jun 15 03:22:35 cmake needs to be abolished Jun 15 03:22:46 i'm finding it a wonderful breeze. Jun 15 03:23:11 cmake is a WMD Jun 15 03:23:15 lol Jun 15 03:23:17 what about scons? Jun 15 03:23:23 WMD with scales? Jun 15 03:23:31 scons is a tiny bit less evil Jun 15 03:24:11 imake :P Jun 15 03:24:12 what is good? Jun 15 03:24:20 if scons is evil? Jun 15 03:24:25 at least scons isn't yet another language Jun 15 03:24:40 mmmmmmmm xmkmf Jun 15 03:24:51 isn't that a german rock group? Jun 15 03:26:07 har! Jun 15 03:26:19 KMFDM is a make system too? Jun 15 03:27:24 xmkmf fails my "has sanely googlable documentation" test. Jun 15 03:27:38 screw google Jun 15 03:27:42 lol Jun 15 03:27:46 non googleable docs are a good thing. Jun 15 03:27:55 * pru_evtout_2 starts typing in url, starting with a.com Jun 15 03:28:52 when a search engine fails to search, it is useless crap. Jun 15 03:29:51 * pru_evtout_2 gets to a.com/ao on his anti-google-search search Jun 15 03:30:17 i suppose i should assume xmkmf will be in the url. that might speed things up a bit. Jun 15 03:32:15 man pages Jun 15 03:52:54 come on opkg.. Jun 15 03:59:09 crap did the powersave governor get enabled by default?.. Jun 15 05:06:24 <_av500_> -ENOSLEEP Jun 15 05:06:29 good moaning Jun 15 05:07:22 hi Jun 15 05:07:42 morning Jun 15 05:08:05 so I accidently formated my bbk's usb drive image Jun 15 05:08:38 and i cant seem to get it to boot from the microsd Jun 15 05:08:45 any suggestions? Jun 15 05:09:15 does anyone have any recent experience compiling the SGX drivers under Angstrom? I'm trying to compile VLC, and it depends on libgles-omap3, which doesn't seem to compile any more. The bitbake recipe is looking for files that don't exist in the TI SDK. Jun 15 05:09:43 no experience Jun 15 05:09:48 DumDum_: yikes. are you sure your microsd card is bootable and working? Jun 15 05:10:17 i used it once before to update the kernal Jun 15 05:10:26 <_av500_> hold the user button Jun 15 05:10:29 <_av500_> when powering up Jun 15 05:10:44 <_av500_> Vito``: angstrom has vlc, no? Jun 15 05:11:21 _av500_: it has the recipe for it, but it's not compiled by default for the BeagleBone Black, it seems. and it doesn't seem to compile at all right now Jun 15 05:11:51 <_av500_> well, there are no sgx drivers for BBB yet Jun 15 05:12:11 <_av500_> and libgles-omap3 is wrong anyway Jun 15 05:12:56 _av500_ I did earlier, just tried again and all 4 lights went solid for ~1 second and now they are flashing, we will see if it works this time Jun 15 05:13:31 _av500_: does that mean the recipe is wrong? Jun 15 05:14:46 <_av500_> no Jun 15 05:14:52 <_av500_> its for beableboard xm Jun 15 05:18:23 _av500_: I see. It sounds like I want to tell VLC to not use SGX stuff at all, then. Jun 15 05:19:41 hi everyone! was thinking to use a couple bb blacks... Jun 15 05:19:50 one for icecast another for nginx Jun 15 05:20:18 would there be super limitations if i used the ubuntu for it? Jun 15 05:25:11 <_av500_> no Jun 15 05:25:13 voe: icecast has super low hw requirements. I used to run it on an OMAP1 Jun 15 05:25:26 unless you bring a source client and encoding into the mix Jun 15 05:25:43 * dm8tbr should know, being an icecast maintainer and all that Jun 15 05:25:48 <_av500_> the BBB cpu can even encode audio Jun 15 05:26:54 smooooooth... Jun 15 05:27:11 <_av500_> it supports both kins of music Jun 15 05:27:13 <_av500_> kinds Jun 15 05:28:37 _av500_ it takes 45mins right? Jun 15 05:28:48 <_av500_> yeah Jun 15 05:28:53 <_av500_> it takes long Jun 15 05:29:13 <_av500_> you should be able to ssh in and see Jun 15 05:31:27 I am running osx, and for some reason the bbk usb isnot in my network list Jun 15 05:41:30 15 more mins, if after 45mins should I give it extra time or try again? Jun 15 05:51:01 _av500_: so its been 45 mins, and no change, lights still blinking Jun 15 06:19:16 i had vlc running on my windows before Jun 15 06:19:46 would i be better off with vlc or icecast or not much difference? Jun 15 07:02:52 <_av500_> for audio streaming? Jun 15 07:02:56 <_av500_> icecast should be enough Jun 15 07:10:49 hi Jun 15 07:12:26 <_av500_> lo Jun 15 07:13:39 in Jun 15 07:16:05 beer Jun 15 07:23:30 <_av500_> mranostay: with kiddie flavours? Jun 15 07:27:03 so is this normal? http://www.thelocal.de/society/20130614-50295.html Jun 15 07:27:22 guiness flavours Jun 15 07:32:31 <_av500_> emeb_mac: amongs cow breeders, I guess so Jun 15 07:32:32 _av500_: stripping out X11 support allowed VLC to compile just fine, thanks for the pointer Jun 15 07:33:31 <_av500_> emeb_mac: thelocal.de, wtf Jun 15 07:34:17 _av500_: via boingboing Jun 15 07:36:02 a cow named "nastygirl".

Jun 15 12:00:04 johanBeagle hm because nobody build it? Jun 15 12:01:47 So how is the stuff built on http://feeds.angstrom-distribution.org/feeds/v2012.12/ipk/eglibc/armv7a-vfp-neon/ ? Jun 15 12:03:23 I noticed it is available on armv7a, and other versions. Is there somewhere documentation how to built something that is not available as a packages for a specific ARCH? Jun 15 12:05:25 so use that Jun 15 12:05:31 I doubt vfp matters for it Jun 15 12:07:38 I am just asking because "opkg install usb-modeswitch" did not find the package. Jun 15 12:18:36 Hello, not a build expert, but if I wanted to compile the 6/6 kernel, what tag should I use for the git checkout command? Examples on the web say 'git checkout 3.8' but I'm guessing that is the head of 3.8, which is changing? Because it doesn't currently compile due to an error. So I'd like to compile against a known working tag Jun 15 12:34:54 johanBeagle did you opkg update before? Jun 15 13:19:33 hello, I just got a couple of A5B bones, and while trying using ubuntu from the SD card i get this error: https://groups.google.com/forum/?fromgroups#!topic/beagleboard/Vp4pxwHm8BU I didn't quite understand what the current preferred workaround is, if it is something i can fix locally that'd be great Jun 15 13:19:51 [ 9.150644] libphy: PHY 4a101000.mdio:01 not found Jun 15 13:19:52 [ 9.155748] net eth0: phy 4a101000.mdio:01 not found on slave 1 Jun 15 13:20:30 i prepared the sd card with the setup_sdcard script with raring rootfs Jun 15 13:22:14 i didn't quite understand if that's an uboot issue or i have to solder a capacitor Jun 15 13:24:48 with uboot i mean this: http://circuitco.com/support/index.php?title=BeagleBone#Ethernet_unable_to_obtain_a_lease.5BA4_Only.5D Etherent PHY Default Configuration [A3,A4,A5,A6] Jun 15 13:33:43 woglinde: yes I did.

Jun 15 17:12:16 * dwery points at mru Jun 15 17:16:06 just wondering if anyone can help me find a beaglebone-black retailer in india/bangalore Jun 15 17:16:14 Hello, been trying to build a BBB image. When I come to run it, I notice that it is built to address 0x80008000, not 80200000 like some instructions on the web. So, I set loadaddr to 0x80008000 and try to boot it, but I get an error as shown here: http://pastebin.com/0age98cu I'm guessing it is something silly, anyone recognize this? Is there some other enviro variable I should have set before Jun 15 17:16:14 doing the boot? Jun 15 17:20:18 mkimage -l says my image is ARM Linux Kernel (uncompressed), about 4Mbytes sie and Load and Entry points are both 80008000 and Image name is Linux-3.8.13-00650-gee56260 (filename is uImage-dtb.am335x-boneblack) Jun 15 17:22:23 morning Jun 15 17:22:30 moaning Jun 15 17:23:56 * mranostay gets ready for horse meatballs at IKDEA Jun 15 17:23:59 *IKEA Jun 15 17:24:53 <_av500_> iDEA Jun 15 17:30:38 _av500_: can we distill horse? Jun 15 17:31:45 horse flavoured vodka! Jun 15 17:33:12 horse is cool Jun 15 17:36:12 <_av500_> mranostay: yes, we can! Jun 15 17:39:20 I don't know how to update the u-boot on my BBB (yet!) and don't wish to currently, but my built Linux image is at address 0x80008000, but u-boot default loadaddr is 0x80200000. Should it work if I just setenv loadaddr to 0x80008000 or do I need to fix something in my build? Not sure where the address is defined in the source code Jun 15 17:41:12 <_av500_> in the kernel config or so Jun 15 17:41:15 <_av500_> or in the DT file Jun 15 17:42:16 hm, I can see a beaglebone_defconfig and a Kconfig file, neither seem to have this address in them Jun 15 17:42:28 why you need to update u-boot? Jun 15 17:42:40 because it is there? Jun 15 17:43:21 <_av500_> no binary left un-updated Jun 15 17:46:33 rice out your beaglebone? Jun 15 17:47:03 no, don't wish to update u-boot. I was just wondering if that was the cause for my built image to have failed. Here's what I did: I compiled up on my intel server u-boot (so that I had mkimage), and then compiled the BBB kernel following these instructions: http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel . Then, when I type mkimage -l, I can see that the loadaddr and Jun 15 17:47:03 entrypoint are 0x80008000. So, I do setenv loadaddr to 0x80008000 and try to boot the image. Sadly it fails with this error: http://pastebin.com/0age98cu . I was clutching at straws, wondering if it was uboot enviro var related, or some more serious error Jun 15 17:47:05 maybe so that it boots via tftp :P Jun 15 17:48:09 * kfoltman was thinking that maybe kernel should not be read at its start address, but a little bit above (80200000?) and relocated from there Jun 15 17:48:12 hehe yeah I'm booting via tftp. Does that work? Jun 15 17:48:30 shabaz: using what version of uboot? Jun 15 17:49:17 shabaz: did you try loading it at the original loadaddr instead of setting it to a different value? Jun 15 17:49:37 regardless of entry point Jun 15 17:51:22 my BBB has version 2013.04-dirty (May 20 2013 - 14:30:06). Yes, tried at 0x80200000 first, which is the default. That hung at "Uncompressing the kernel... done, booting the kernel". That's when I checked with mkimage -l, to see what the load and entry addresses were Jun 15 17:52:02 shabaz: hm, are you using the correct DTB with it? Jun 15 17:58:30 shabaz: BTW, "Starting kernel ... data abort" means that it fails earlier than "done, booting the kernel", right? Jun 15 17:58:33 the -common.dtsi file says under memory "reg = <0x80000000 0x10000000>;" Jun 15 17:58:41 So, I have a BBB and I'm trying to insert my own IRQ-handlers by replacing the address table at 4030CE20. I do a swi/svc but it just hangs. Sometimes I've managed to get a data abort but it seems to load the default u-boot handler. Should it not be enough to replace the address? Jun 15 17:59:13 shabaz: that only says that RAM is there, not that this RAM is free to use (u-boot may be using some of it) Jun 15 17:59:37 shabaz: which would explain why it doesn't get to the uncompressing stage Jun 15 18:00:22 Sorry should have pasted the whole lot; it is here: http://pastebin.com/9LQ3ZwNU Jun 15 18:00:55 shabaz: anyway, AFAIR the procedure was that you need to load the kernel AND the device tree, and then pass those two to bootm Jun 15 18:01:20 I think printenv in uboot may shed some light on the process - you'll see what the original scripts do Jun 15 18:01:59 kfoltman: ohhh I see. cool, I'll look at the printenv in more detail. Jun 15 18:02:23 I think hanging after decompression may be caused by missing device tree, basically, the kernel doesn't have enough data to proceed - or by device tree from the wrong version (beaglebone vs beaglebone black etc.) Jun 15 18:03:07 But it's been a while since I last played with BBB - at this point, I'm stuck for long time in STM32 USB horror Jun 15 18:05:43 oh, good luck with the USB. Another area I'm not really familiar with! Jun 15 18:06:59 me neither - I have a half-decent book (USB Complete), STM32 docs (sometimes giving confusing/conflicting info) and some internet docs, and it's an uphill battle Jun 15 18:09:45 I see.. I noticed a google SoC USB analyer, was going to investigate that at some stage. But I guess you already know about that. If/when I get this compiled image working, I'll document it. There are lots of web pages now where people have compiled it, but some instructions are missing a few steps I guess. Jun 15 18:11:25 haha lol Jun 15 18:11:26 Windows Embedded Compact 2013 Jun 15 18:12:57 * mranostay vomits Jun 15 18:18:48 hello Jun 15 18:19:52 woglinde: who would run that? Jun 15 18:20:18 Embedded Compact... someone in marketing was on something Jun 15 18:23:45 I need some help, I accidently formatted my BBK's usb image last night...I tried to restore from a micro sd but I can't get my mac to see the USB as a network interface or usb drive anymore Jun 15 18:23:55 BBK? Jun 15 18:24:48 sorry beagle bone black Jun 15 18:25:09 no idea why I call it bbk* Jun 15 18:31:35 Steven_: BBB is the norm I believe Jun 15 18:32:00 mranostay ms claims rfid readers Jun 15 18:35:48 woglinde: claims? Jun 15 19:02:14 mranostay the article says so Jun 15 19:23:16 Hey Beaglers. I'm using the Ubuntu image from http://www.armhf.com/index.php/download/. I have a 8GB sd card, but it only uses 2GB. How can I increase my root fs to occupy the whole card? Jun 15 19:23:56 narcos, what FS is on it ext4? Jun 15 19:24:26 yes Jun 15 19:26:00 google knows how to do this :0 Jun 15 19:26:14 heh, ta Jun 15 19:26:18 I'm Googling too Jun 15 19:26:20 including #exactsteps Jun 15 19:26:42 Hm Jun 15 19:26:43 url? Jun 15 19:27:16 I notice some suggest creating a new partition, and mounting /home or something under it Jun 15 19:27:23 that could be a good idea Jun 15 19:27:25 ext3 and ext4 can be treated as ext2, right? they'll just rebuild some stuff if they determine that it's invalid because an ext2 tool manipulated the structures? Jun 15 19:31:47 ka6sox: Could I have the URL you're looking at?.? Jun 15 19:32:20 I found how to increase the fs, but not the partition, using resize2fs Jun 15 19:35:07 Anyone have some working u-boot commands to launch an image via TFTP? As a test, I've copied a working released image (6/6 I think or the one before it) from my BBB /boot folder called uImage-3.8.13 and the am335x-boneblack.dtb to my tftp server, and mkimage -l shows that the working image is at address 0x80008000 so I've done tftpboot 0x80008000 uImage-3.8.13 and tftpboot 0x80F80000 Jun 15 19:35:08 am335x-boneblack.dtb and then bootm 0x80008000 but it hangs after "Starting kernel... data abort MAYBE you should read doc/READme.arm-unaligned-accesses". This is the same symptom as my own compiled image, so I'm guessing I'm not specifying all the right parameters in u-boot. Jun 15 19:36:23 when it hangs with the release image, the program counter is at 0x80008008, which is the same place as my own compiled image. so seems it may be a header? Jun 15 19:41:11 so Im trying to install ubuntu on my beaglebone black. I made an img on a sd card and im just getting a black screen when i try to boot from it (just plud in the sd and give power) Its a fresh beablebone. I read on elinux.org I need to install "mainline U-Boot" I do NOT have access to a lan cable, not seeing how to upgrade over teather Jun 15 19:44:01 is it not possible to update over teather? the getting started is makeing it sound like I cant winstall wireless without first useing a lan cable Jun 15 20:24:56 hello Jun 15 21:00:04 Can the beaglebone power a mechanical external passport HDD which uses on USB port? Jun 15 21:00:26 I know a Hub is obviously the preferred solution, but can it be done? :) Jun 15 21:01:06 Beaglebone Black, I should say. Jun 15 21:14:48 <_Sy_> hello all....

Jun 15 22:41:48 yeah Jun 15 22:41:53 so, short answer: Jun 15 22:41:58 setenv ethact usb_ether Jun 15 22:42:14 this will make the primary network device used the usb one, rather than the "regular" one Jun 15 22:42:17 (the cpsw one) Jun 15 22:42:43 Then all the normal network commands (dhcp, tftp) will try usb first Jun 15 22:42:50 okok Jun 15 22:43:14 ok nice! from here i can take and analyze it Jun 15 22:43:16 thx for the info Jun 15 22:43:40 np Jun 15 22:44:34 Tartarus: if intrested to follow the project https://github.com/ungureanuvladvictor/BBBabb Jun 15 22:44:59 maybe i will bug more with questions these days, need to drop to u-boot kernel and initrd Jun 15 22:45:03 watching Jun 15 22:45:43 * vvu|Mobile is going back to refactoring code, have a great day Tartarus! Jun 15 22:47:23 you too Jun 15 23:42:34 * etalk http://etalk.22web.org p2p encrypted chat/message system, Give it a try its free! Jun 15 23:44:18 whoa - IRC spam! Jun 15 23:47:56 yes, it's not just for green cards any more Jun 15 23:57:04 i have creeper cards if you need those Jun 15 23:59:32 green cards = puffery Jun 15 23:59:38 who wants to live in teh US of A Jun 16 00:00:35 worse places Jun 16 00:00:40 yet they keep creeping in, legal or not. go figure! Jun 16 00:00:41 whewre? Jun 16 00:00:46 idk i rather like it Jun 16 00:01:28 native compiling on a BB... kill me know Jun 16 00:01:30 england. Jun 16 00:01:30 *now Jun 16 00:02:12 my engineer has got non native compiling working for our applicaitons. Jun 16 00:02:22 but not kernel stuff Jun 16 00:02:22 too many trolls in england Jun 16 00:02:51 New Zealand has the Dotcom Troll Jun 16 00:03:00 who let that dodgey German in Jun 16 00:04:06 Does anyone *really* know if you can use a uSD card with a Black other than booting from it? It totally doesn't work for me, and I've come across a few passing mentions about not having an SD in place when booting from eMMC. Followup Q would be can you get the thing to recognize the SD if inserted post-boot? Serious answers only, no creepers of phonies... Jun 16 00:04:33 i rather not be on islands where i can easily escape them Jun 16 00:04:57 they're all islands, really Jun 16 00:05:06 some are just a lot bigger than others Jun 16 00:06:04 that is one way of looking at it Jun 16 00:06:57 martinm: are you tryign to use both the SDcard and the emmc togehter? Jun 16 00:07:11 yeah, that was the idea Jun 16 00:07:20 have not tryed that Jun 16 00:07:43 mranostay: what do you think? Possible? Jun 16 00:08:00 if the SD card is in it just hangs at three LEDs IME Jun 16 00:08:13 hmmm don't remember the muxing Jun 16 00:08:35 it must be possble Jun 16 00:08:37 but it has to be or i have no clue how koen's flasher image would work Jun 16 00:08:48 because for me to write my image to the emmc Jun 16 00:08:54 i start by putting on on sdcard Jun 16 00:09:02 now sd card insert totally doesn't work :) Jun 16 00:09:04 mranostay: snap Jun 16 00:09:25 not sure if someone didn't wire it up or there is no sw for it Jun 16 00:09:28 yeah, there are certainly separate MMC0 abd MMC1 pins Jun 16 00:10:15 so it may just be something screwy in the early (?) boot Jun 16 00:11:12 everthing is broken Jun 16 00:11:27 oh well, guess I'll have to cons up a level translator so i can plug in to a Real Serial port Jun 16 00:11:43 im messing with a 15W cree RGBW led today Jun 16 00:11:47 geepers its bright Jun 16 00:12:45 * SpeedEvil sighs and wishes good R G LEDs were available. Jun 16 00:12:52 B isn't bad. Jun 16 00:13:05 but G is about 1/3 as efficient as B Jun 16 00:13:19 You can get 65% efficient blue. Jun 16 00:13:21 you dont' need nearly as much G as B of course Jun 16 00:13:26 * martinm blames quantum physicists Jun 16 00:13:27 True. Jun 16 00:13:42 Cree hit 200lumens / Watt Jun 16 00:13:44 thats nuts Jun 16 00:14:56 yeah Jun 16 00:15:11 But 100lm/W is the best you can get in green Jun 16 00:15:18 actually - I think they hit 130 Jun 16 00:15:32 they hit 200 Jun 16 00:15:35 actually Jun 16 00:15:40 green Jun 16 00:16:11 http://www.cree.com/led-components-and-modules/products/xlamp/arrays-directional/xlamp-mkr Jun 16 00:16:14 it is in white Jun 16 00:16:17 yes. Jun 16 00:16:31 There are no efficient greens Jun 16 00:17:52 The most efficient LEDs for illumination are cyan. But the big caveat there is it's only scotopic vision Jun 16 00:19:25 Also I find it annoying that cree does not sell phosphors for remote phospor apps Jun 16 00:20:17 oh realy Jun 16 00:23:38 http://hyperphysics.phy-astr.gsu.edu/hbase/vision/efficacy.html Jun 16 00:26:42 I see the claim of "up to 200 l/W", but their own specs seem to fall 'way short of that... about a factor of two, at least at 85° where most of the specs are given Jun 16 00:30:27 martinm: Ah -0 you have to know th ratings bullshit. Jun 16 00:30:50 I have not read the datasheet, but in general, that 'up to' figure will be true for 1/5th maximum output Jun 16 00:31:04 And 25C Jun 16 00:31:11 ah, found a possible explanation inthe press release. up to 200 for 1W at 25° - sure, the efficiency drops with both power and temp Jun 16 00:31:46 It is not always bullshit - sometimes it's actually worth using 10 10W LEDs run at 2W per, in a design. Jun 16 00:32:03 the datasheet figures are for 8 or 9 W (700 mA at typical 85° voltage) Jun 16 00:40:35 p Jun 16 00:40:58 q Jun 16 00:41:28 u Jun 16 01:32:14 Hi vvu, if you don't mind, I'm placing a link to your project on e14's site, people will find it interesting Jun 16 01:34:26 btw, had a question for you (ka6sox suggested you may know the answer), but I might e-mail it since it's rather long for IRC - long story short, been trying to get an image to boot via TFTP so we can document the process, and not sure why the final image does not run - could be a u-boot enviro variable issue I suppose Jun 16 01:47:00 hi, which outlet is selling the latest revision of the beagleboard? **** ENDING LOGGING AT Sun Jun 16 02:59:58 2013
