**** BEGIN LOGGING AT Fri Jun 05 02:59:59 2015 Jun 05 03:00:18 I will try learning more about this tomorrow. Jun 05 03:50:24 So I got my BBB booting Ubuntu Server 14.04 from the micro sd. But how do I get Ubuntu on the eMMC so it boots like this every time? Jun 05 04:17:32 hi guys is there any reason why my beaglebone black is not detecting any microsd card and can that be seen in logs etc and fixed? All I get with it booted from the emmc is it saying errror 110 Jun 05 04:20:10 anything connected to P8/P9? Jun 05 04:24:08 initially I had a cape i made it and worked fine for months. with it removed it just doesnt intialize the microsd card and gives the error -110 with it Jun 05 04:24:57 is the card readable elsewhere? Jun 05 04:25:53 yeah i can read it my odroid u3 and on my laptop\ Jun 05 04:48:47 hi all, i'm new to the IRC. I started using a beaglebone several months ago, and got some simple scripts set up through the cloud9 IDE interface at that time. It ran flawlessly for a month or so, when I took the system offline. I have reconnected it to my network, and while the system boots (I can SSH into it), I'm having issues with cloud9. When I navigate to :3000, I get the "loading your workspace" screen flash, when it then kick Jun 05 04:48:59 Does anyone have any ideas on how to fix this, or instructions on how to reinstall cloud9? Jun 05 07:25:23 HEY Jun 05 07:25:51 I LIKE TO UP MY UART IN bbb Jun 05 07:26:27 IM RUNNING UBUNTU IN THAT HOW CAN I Jun 05 07:26:44 With kernal 3.15 Jun 05 07:32:55 has anybody worked with CO2 sensors before? i would like to buy one and would appreciate recommendations Jun 05 07:52:33 guys Jun 05 08:00:15 I am using beagle board C3 and I built the images for it using this link http://android.serverbox.ch/?p=1273 and http://www.embarcados.com.br/beaglebone-black-yocto-dizzy-versao-1-7/ Jun 05 08:00:39 but during boot up I stuck at Texas Instruments X-Loader 1.4.2 (Feb 19 2009 - 12:01:24) Reading boot sector Jun 05 08:00:45 please can you help me? Jun 05 08:01:48 Huh...not even anything about u-boot? Jun 05 08:05:55 endrift: no no Jun 05 08:06:11 I think the primary loader is failing to get u-boot from sd card Jun 05 09:20:23 i have a BBB rev A5C which does not boot while pressing S2 (also when grounding P8.43, and also when pulling P8.45 to +3.3V for netboot). power led stays on and nothing more, on the serial console just prints "C" every second or so (or stays mute when trying to netboot). other from that, the present system works good. other ways to flash it? Jun 05 09:22:37 samael: does it see a µSD card when booted from eMMC? Jun 05 09:35:40 tbr: seems not. but i remember older boards (or kernels? i'm using 3.8.13-bone24 here) does not support uSD hotplug. not sure tough Jun 05 09:37:41 do any of these apply to BeagleBoardBlack? https://wiki.ubuntu.com/ARM/Server/Install Jun 05 09:39:01 StephaneCharette: nope. RCN maintains instructions and images. Canonical also started offering prebuilt Snappy core images for BBB. Jun 05 09:39:21 no, can't see the uSD neither booting with it plugged in, nor inserting it later Jun 05 09:39:43 but still can't understand why I cannot boot from ethernet Jun 05 09:40:30 samael: you can probably use serial or USB for flashing, it's not commonly used though. There is a tool to do things. I think vvu wrote it. Jun 05 09:51:03 tbr: find it, i'll try. thanks! Jun 05 10:05:59 usb boot process starts but fails at an early stage. i thinks this board has problems itself Jun 05 10:09:01 not unlikely if the SDIO for the µSD is broken Jun 05 10:36:11 Hello, anybody here has experience with long term unattended deployment of BBBs? I am building some data logging systems for a client, RO file system on eMMC, good power supply, writing sensor data to a usb stick which is supposed to be frequently unplugged to copy data Jun 05 10:37:39 I am interested to learn about MTBF and gotchas with this setup. I am aiming at a few years of operations without upgrades. Jun 05 10:38:11 so you are looking for somebody that has BBBs deployed since 5years? Jun 05 10:42:10 well, I have a few in the wild Jun 05 10:42:20 it has been at least a year Jun 05 10:42:33 maybe more, I don't remember when the bbb first got out Jun 05 10:43:15 only issue is that sometimes with power failures the board won't boot Jun 05 10:44:22 IIRC I read somewhere it was related to debug usart not being properly grounded and reading random garbage during bootloader stage Jun 05 10:44:30 or something like that Jun 05 10:44:53 I implemented the hw solution but never checked scientifically Jun 05 10:45:35 other than that, it works good, even without ro fs, etc. Jun 05 10:46:10 oh, and USB was kind of delicate..may have been changed with recent kernels tho Jun 05 10:46:21 jsolano, ^ there you go Jun 05 10:58:12 c10ud: thanks, power issues is what the testing I am doing is focusing on, I am searching for ideas to automate reboot testing before deplying them Jun 05 11:22:40 hi all :) Jun 05 11:22:56 Can you may help me? I am trying to get my c++ application running on my BBB. Jun 05 11:23:38 no idea if we can help you Jun 05 11:24:07 I have setup my IDE and so on to compile for ARM and the executable is shown as [arm/le] in eclipse. Jun 05 11:24:22 when I copy the file to my bbb and change the right with chmod +x for the file Jun 05 11:24:28 I can't execute it Jun 05 11:24:35 it mentions no such file or directory Jun 05 11:24:51 when it does not have the execution rights, it says no permissons Jun 05 11:24:55 right Jun 05 11:24:58 I use ./filename Jun 05 11:25:01 to run it Jun 05 11:25:18 run "ldd filename" Jun 05 11:25:23 what does it say? Jun 05 11:25:52 give me 1 min Jun 05 11:25:53 i try Jun 05 11:25:55 thank you :) Jun 05 11:26:13 No command run found Jun 05 11:26:21 ? Jun 05 11:26:33 debian@beaglebone:~/Dev$ run -bash: run: command not found Jun 05 11:26:45 not run Jun 05 11:26:50 oh Jun 05 11:26:51 ldd filename Jun 05 11:26:52 just ldd Jun 05 11:26:54 sorry :D Jun 05 11:27:15 not a dynamic executable Jun 05 11:27:52 ok Jun 05 11:28:08 run "file filename" Jun 05 11:28:44 the filename is "Receiver" Jun 05 11:28:45 Receiver: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=0x8f495ff6d3f5ca00668dd34c27c65ccc603240e5, not stripped Jun 05 11:34:44 I am using the gcc-arm-linux-gnueabi and g++-arm-linux-gnueabi toolchain Jun 05 11:34:52 I am developing on Ubuntu with eclipse Jun 05 11:57:10 i am mixing something up with 32/64 bit? Jun 05 11:57:22 am i mixing something up with 32 and 64 bit? Jun 05 11:57:56 no, 32 bit is fint Jun 05 11:57:57 fine Jun 05 12:02:05 hi guys..can I repeat my question? Jun 05 12:04:46 kanupatar: sure Jun 05 12:05:03 but I can tell you right now that BBB images dont work on a BB C3 Jun 05 12:05:48 if you want android on a BBB, you need to get a BBB Jun 05 12:07:13 av500: ohh, then how can i build bb c3 images in yocto? Jun 05 12:07:56 av500: do you think I can solve the problem by installing the libc6-armel, libsfgcc1 and libsfstdc++6 packages? Jun 05 12:09:37 Does anyone know the approximate BOM costs for the beaglebone black at say 100 or 1000 off quantities? Jun 05 12:09:38 kanupatar: I know little about yocto Jun 05 12:09:45 but BB C3 should be a supported target Jun 05 12:09:49 its old enough after all Jun 05 12:10:15 trepidaciousMBR2: since it sells for $45, I would say <=$45 Jun 05 12:11:14 kanupatar: the BB C3 is quute old and most ppl stopped caring about it Jun 05 12:11:16 quite Jun 05 12:19:59 ac500: Jun 05 12:20:00 I solved my problem by copying ld-linux.so.3 which is located under /lib/arm-linux-gnueabihf/ to the upper directory /lib/. Jun 05 12:20:13 av500: ohh..i need to build a kernel and QT for c3 Jun 05 12:21:48 av500: here is the explaination whats the problem: I solved my problem by copying ld-linux.so.3 which is located under /lib/arm-linux-gnueabihf/ to the upper directory /lib/. Jun 05 12:21:54 https://wiki.linaro.org/OfficeofCTO/HardFloat/LinkerPathCallApr2012 Jun 05 12:22:51 Hello gentlemen. I have aquestion about a video streaming application using the BBB. My main problem is that the end user is not going to shut down the board gracefully, he just wants to unplug the power. Is it enough to mount the mass storage as read-only to avoid data corruption? Jun 05 12:23:07 here you get more stuff to read, if anybody else is faced with this problem: http://ubuntuforums.org/showthread.php?t=2031471&s=703a20d737c3134214ddff18bfa12d88 Jun 05 12:25:16 sla: good Jun 05 12:25:38 :) Jun 05 12:25:41 thank you! Jun 05 12:28:39 i am out =) see you Jun 05 12:38:54 Hi! I'm trying to deploy a rebuild kernel (rebuilt with the script of RobertCNelson) to a running Debian on the BeagleBoneBlack to use the Nh5cape. I did all steps on http://elinux.org/Nh5capeSoftware to rebuild the kernel. Can somebody explain to me what I have to to with the files in the deploy folder (*zimage, *.deb,...)? Thanks very much! Jun 05 13:00:30 MisterBoneBeagle: I'd guess you install the resulting kernel .deb file Jun 05 13:01:46 * jkridner wonders if those patches are or should be in http://github.com/beagleboard/linux Jun 05 13:15:21 Hey, I have a question to the BeagleBoard Black: How many Pins support pwm? Jun 05 13:16:03 check the SRM Jun 05 13:16:56 (System Reference Manual) Jun 05 13:19:59 ty Jun 05 13:20:22 hmm it says it only has 3 pwm pins ... i need 4 ... is it possible to emulate a pwm pin? Jun 05 13:26:38 Sure. Jun 05 13:35:05 should have stuck around longer.... Jun 05 13:35:10 3 PWM blocks, 8 pins. Jun 05 13:35:28 PRU can "emulate" 25 more without eating up ARM CPU. Jun 05 13:35:38 guess folks just don't know how to use IRC. :( Jun 05 13:36:14 http://beagleboard.org/support/bone101/#headers-pwm Jun 05 13:38:05 Sorry to reiterate this: I have aquestion about a video streaming application using the BBB. My main problem is that the end user is not going to shut down the board gracefully, he just wants to unplug the power. Is it enough to mount the mass storage as read-only to avoid data corruption? Jun 05 13:44:05 May I get a yocto st up procedure for C3 board? Jun 05 13:46:20 GustavoLapasta: if the system is readonly, you have a much lower chance of corruption. Jun 05 13:46:54 GustavoLapasta: avoid using a filesystem with a journal, and mount it with the sync option. Jun 05 13:48:22 jkridner: Got the display and initial capacitive touch working on the 4.1 kernel through overlays, some issue with backlight PWM I should sort out today evening Jun 05 13:55:38 agmlego|skynet, which filesystem would you recommend for this kind of application? Plain old fat32? Jun 05 13:56:24 wait, cannot install root on fat32. I guess ext2 is ok? Jun 05 14:21:24 rcn-ee: Got my display working in v4.1 kernel with overlay, but there's some issue with the backlight (will show you the logs when I'm back home, but IIRC error was related to ocp and interrupts for ehrpwm2) Jun 05 14:22:20 Abhishek_, did you use bone6 out of the repo, or from the build.. (it may have something i've fixed in the repo, but not the apt-get repo..) Jun 05 14:22:38 rcn-ee: bone6 from apt-get Jun 05 14:22:54 okay... (lots of patches in flight at the moment. ;) ) Jun 05 14:24:14 hum... (looking at git logs)... bone6 is where i fixed the pwm's. ;) Jun 05 14:25:13 just remember to use the newer dtc with 4.1, that could cause one of the "failed to resolve ocp" issues.. Jun 05 14:25:39 ah yes, the error message was something resembling that Jun 05 14:27:15 also having the -@ flags helps too: https://github.com/RobertCNelson/dtb-rebuilder/commit/1b9cddb33fa6fc769e5c9fecc08d0a643b3e8173 Jun 05 14:49:21 ohai Jun 05 14:49:28 http://www.jks.com/wrx/wrx.html Jun 05 14:49:39 this is interesting as shit, not sure if it's been previously discussed here Jun 05 14:50:54 the SDR and GPS stuff may or may not have broad applicability to this channel, but one particular hack, using a reduced subset of the cape headers, is really interesting to me. "The 26-pin header with the non-standard long tail length is a part stocked by distributors, whereas the 46-pin is not." Jun 05 15:09:26 rcn-ee: Also I found that "touching" the lxqt start button does not open the start menu but pressing on buttons work. Hints? Jun 05 15:09:53 Faced something similar on the BBB exp c? Jun 05 15:13:34 sorry, been lazy, haven't even "calibrated" the screen to even test touch "start"... Jun 05 15:13:47 just hit the screen and see if the mouse moves.. = rcn-ee tested. ;) Jun 05 15:14:30 with a mouse, there is a slight delay in lxqt... so maybe something simiar.. Jun 05 15:31:13 rcn-ee "approved" ;) Jun 05 16:20:22 Does the beaglebone black rev C run headless? Jun 05 16:20:32 sure. Jun 05 16:20:51 just like any other linyx box can Jun 05 16:20:55 ok, I was reading the adafruit page on it and it says it does not run headless Jun 05 16:21:09 is that so. Jun 05 16:21:20 Yep want a pastebin? Jun 05 16:21:30 no, just a link. Jun 05 16:21:38 waite one Jun 05 16:22:41 http://www.adafruit.com/products/1996 Jun 05 16:22:52 6tht paragraph of the Description Jun 05 16:24:20 that IA not at all what that says. Jun 05 16:24:27 not even close. Jun 05 16:24:42 IA? Jun 05 16:24:52 *is Jun 05 16:24:58 mobile keyboard. Jun 05 16:25:08 :) Jun 05 16:25:15 so, that is bunk right? Jun 05 16:25:31 no. Jun 05 16:25:40 you are reading it wrong. Jun 05 16:26:20 ok, I guess I did. They didn't mean to run headless, they mean t hat if you don't have anything to work with, a serial cable is needed Jun 05 16:26:25 That I would agree with Jun 05 16:26:31 yup. Jun 05 16:26:50 man, they should talk american :) Jun 05 16:27:02 uh... Jun 05 16:27:09 just joking Jun 05 16:27:29 Thanks, have a wonderful day Jun 05 16:28:11 I said that because in the big machine world, headless means no keyboard, not monitor Jun 05 16:29:00 bye Jun 05 16:34:33 uh, that is also false, but whatever. Jun 05 16:42:49 if I want to cross compile from AMD64 for my BeagleBoardBlack, should I be using gcc-arm-linux-gnueabi or gcc-arm-linux-gnueabihf? Jun 05 16:43:16 hf Jun 05 16:43:20 thanks Jun 05 16:43:34 unless you run an armel (vs armhf) install Jun 05 16:43:42 (which is unlikely) Jun 05 17:05:59 rcn-ee: seeing anything interesting in the environment vars? Jun 05 17:06:31 rcn-ee: connection seems to have been lost during a different point. Jun 05 17:06:49 rcn-ee: I'm wondering if my Internet provider (Comcast) just super-sucks. Jun 05 17:06:57 (I know they do) Jun 05 17:08:14 i was thing permissions... Jun 05 17:08:34 it might be a timeout, if builds is outside your home network.. Jun 05 17:09:06 my home provider sucks, so i have a kitchen timer on the modem to reset every 8 hours for a minute, but rsync recovers just fine. ;) Jun 05 17:10:09 i wonder if we spawn a task to report size every 30 seconds? Jun 05 17:11:05 rcn-ee: that could keep traffic going over the line. Jun 05 17:11:31 http://builds.beagleboard.org/builders/build-image/builds/617/steps/shell/logs/stdio dies in a different place though. Jun 05 17:15:34 it does, but the other spot is also slow.. (gz'ing the *.tar..) Jun 05 17:15:45 https://github.com/beagleboard/image-builder/commit/3db00486e83d11acb4ff679a748572f5db8d8583 Jun 05 17:17:38 617 is tar cvf ${export_filename}.tar ./${export_filename} so armhf-rootfs-debian-wheezy.tar would be 500Mb... Jun 05 17:18:51 bb in a bit.. afternoon off, so i'll be home, having a beer. ;) Jun 05 21:13:29 hello, anybody has experienced a difference in quality between BBB from Circuitco and Element14/Embest? I understand they use the same part specs but I wonder if anybody has seen differences related to long term reliability/MTBF, specially power issues **** ENDING LOGGING AT Sat Jun 06 02:59:58 2015
