**** BEGIN LOGGING AT Fri Feb 06 02:59:59 2015 Feb 06 03:00:44 thanks ds2 - is it one of the chips labeled here? http://elinux.org/images/a/a7/COMP_A5A.jpg Feb 06 03:14:45 Jimbo_, no Feb 06 03:15:31 Jimbo_, or rather, which EEPROM are you referring to? Feb 06 03:15:55 presumably not the eMMC Feb 06 03:16:26 I believe there are a couple smaller FLASH devices; they are likely the devices between the DDR3 and the framer Feb 06 03:19:06 nope. it is a tiny chip Feb 06 03:24:19 Hey bgamari, I'm not sure to be honest. I'm working on a project and was told to try and find a way to increase the EEPROM from 32 kbyte to 128 kbyte Feb 06 03:24:25 Not sure which chip I should be focused on Feb 06 03:24:42 Jimbo_, Why do you need to do this? Feb 06 03:25:38 don't have many details of the intent of the project, just told to explore the possibility Feb 06 03:26:25 hmm Feb 06 03:26:35 Jimbo_, I'd say you likely just want to look at the schematics Feb 06 03:27:02 I’m trying to fsck my beaglebone's SD card but I'm not seeing /dev/mmcblk0 is there any other interface I could run it on? Feb 06 03:27:19 ok bgamari, will do Feb 06 03:28:05 thank you Feb 06 03:29:16 Jimbo_, no worries! Feb 06 03:29:53 Lightsword, you are checking it while it's plugged in to the bone? Feb 06 03:30:11 yeah, its able to boot up but I have a missing partition Feb 06 03:30:17 its booting of the card Feb 06 03:30:38 or rather its missing all the mmcblk partitions in /dev Feb 06 03:30:45 what does dmesg say? Feb 06 03:34:06 https://gist.github.com/jameshilliard/9aa091f9355e9f6c1ad2 Feb 06 06:17:47 HI i want a fully stable ubuntu distro for bbb any sugesstion's Feb 06 06:17:56 #ubuntuarm Feb 06 06:18:33 #ubuntu-arm Feb 06 06:18:55 try /join #channel Feb 06 06:21:39 HI i want a fully stable ubuntu distro for bbb any sugesstion's Feb 06 06:22:03 I downloaded one from http://rcn-ee.net/dev/rootsf but it's dont have any dtb Feb 06 06:22:37 Hi this is the first time to use beaglebone black I need the most effective compilers or platform to start or web helps or books or how to make my image program Feb 06 06:22:47 I downloaded one from http://rcn-ee.net/dev/rootfs but it's dont have any dtb Feb 06 06:23:01 bunty: have you seen http://beagleboard.org/project/ubuntu/ and you might want to avoid repeating your question so often Feb 06 06:24:10 Hey folks, I have a bbb running with a prebuilt arago image contained in the TI-SDK. Is there out of the box support for display capes like the 4.3" from 4D systems? Feb 06 06:24:38 Nerade: ask TI Feb 06 06:25:13 Msnaggar: what are you trying to accomplish with the BBB? Feb 06 06:25:45 In case they havo no support for lcd capes, what are the general steps to include such a support? Feb 06 06:25:58 Nerade: ask TI Feb 06 06:26:37 Controls looms that have quadrature encoder and two servo motor with tension control Feb 06 06:27:41 Nerade: we cannot support TI arago stuff here Feb 06 06:28:05 Msnaggar: the BBB already comes with a compiler Feb 06 06:28:23 and basically its a linux computer, tons of help for that out there Feb 06 06:29:01 Could you suggest to the steps to it Feb 06 06:29:45 okay thanks so far, I wasn't quite sure about the correct channel for asking such questions Feb 06 06:30:17 Wherein never working in linux Feb 06 06:30:45 Nerade: if you can work with the stock debian, it might be easier to get help Feb 06 06:31:02 Msnaggar: as said, you are not the first one to use linux Feb 06 06:31:12 so there is so much information about that out there Feb 06 06:37:16 How can I start with the BBB linux Feb 06 06:37:48 http://beagleboard.org/getting-started Feb 06 06:38:00 did you do all that already? Feb 06 06:38:28 did you read the rest of the website? Feb 06 06:38:49 https://www.google.com/search?q=embedded+linux+getting+started Feb 06 06:39:03 again, so much info out there Feb 06 06:39:14 https://www.youtube.com/watch?v=mtzdQSCKBis Feb 06 06:40:14 Reyes I do all the getting started with BBB Feb 06 06:42:52 I need to do my program that working on the img that I updated to use BBB as mini computer for driven my application Feb 06 06:46:53 yes Feb 06 06:46:54 so? Feb 06 06:47:52 Msnaggar: to be clear, there wont be hand holding or exact steps Feb 06 06:48:02 its your duty to get as far as you can on your own Feb 06 06:48:09 then you can ask specific questions Feb 06 06:48:37 "help me to finish my 3rd year project on time" is not a specific question Feb 06 10:57:30 Hi , i am not able to flash ubuntu on to my bbb while amstrong and debian both are flashing from sd to emmc by pressing the boot switch before power on. Any suggestion . Feb 06 10:57:41 use debian Feb 06 10:57:49 its the officially supported SW Feb 06 10:58:01 but i want to use ubuntu Feb 06 10:58:25 then ask the people that made the ubuntu flasher Feb 06 10:58:30 becoz some command's differ Feb 06 10:59:10 have u ever tried installing ubuntu Feb 06 10:59:12 ?? Feb 06 11:00:48 anybody have any idea or any other solutions. Feb 06 11:11:11 anyone there who have installed ubuntu into his/her bbb permanently Feb 06 11:14:23 #ubuntu-arm Feb 06 13:46:15 i have several cbb-serial capes for 485 communication, using ioctl() to declare the GPIO 1_16 as DE/RE pin as stated here http://inspire.logicsupply.com/2014/09/beaglebone-rs-485-communication.html . while working good on wheezy console images/3.8.13-bone63, i found problems on the last jessie image/3.8.13-bone70 Feb 06 13:47:34 i suspect timing management is wrong, because i receive a reply on the bus after the timeout, before to ask again Feb 06 13:48:21 how can i investigate more? are there some relevant changes in the latest kernel concerning such kind of i/o? Feb 06 13:48:58 (i'm reverting jessie to 3.8.13-bone63 to see what happens) Feb 06 13:57:23 How do you use gpio's on the Beaglebone Black (for a DS18B20 temperature sensor) Feb 06 15:32:31 are there any docs on the eMMC partition format? I.E the info one would need to create an image that could be directly dd'ed to the eMMC device Feb 06 15:32:39 I'm finding plenty of resources for the SD format, but not much in the way of the eMMC ... Feb 06 15:43:49 KaaK: i just create my images from a master installation on the bbb, works well. do you want to directly create a "master" image on another host then? Feb 06 15:44:31 how can we install ubuntu phone on BBB? Feb 06 15:46:21 KaaK: if in doubt, i think you can just use sfdisk to save the partition table of a running bbb and recreate it on a loopback image Feb 06 15:46:26 I've got a "master" that i'd like to turn in to a image that can be easily dd'ed for automation purposes Feb 06 15:47:05 your master is a running bbb or not? Feb 06 15:47:34 its debootstrap'ed (actually multistraped, but same concept) Feb 06 15:48:10 i.e. ive got a tarball of the rootfs contents that I want (and some bbb hardware specific tweaks) Feb 06 15:48:38 and I want to populate a dd'able image with those contents Feb 06 15:49:22 i'd probably write it to a beagle, then boot from an SD and manually create the master image with dd Feb 06 15:50:08 my image skeletons/scaffolds using libguestfs (beats the shit out of losetup) -- just need to get the disk options/geometry/partitions correct Feb 06 15:50:49 meh, i'll keep digging -- thanks for the input though Feb 06 15:52:05 the process needs to be fully automated -- i've currently got u-boot and the kernel builds fully automated, and I want the image building to also be fully automated so it can be triggered for rebuild when kernel/u-boot/rootfs changes occur Feb 06 15:53:50 samael, the sfdisk route worked, thanks! Feb 06 15:56:59 yeah, sfdisk is good for such automated tasks. good then Feb 06 15:57:22 * samael will be trying libguestfs, didn't know it Feb 06 16:07:08 samael, here is an example of libguestfs. Specifically its script interface `guestfish': http://paste.debian.net/144295/ Feb 06 16:07:51 its also nice because it has python bindings (among others). Makes more complicated usages *much* nicer with a full-purpose language Feb 06 16:08:54 I use that script to create skeleton images for another embedded ARM device Feb 06 16:23:23 KaaK: cool, thanks for sharing Feb 06 16:37:02 Hi Feb 06 16:37:46 Someone had problems with 3G modem and Linux with BBB? Feb 06 16:38:28 CleitonBueno, can you be more specific? Feb 06 16:39:53 OK. Feb 06 16:39:54 No 3G modem everything works! With the modem into the USB randomly restarts and case work the modem Feb 06 16:40:09 CleitonBueno: how are you powering the BBB? Feb 06 16:40:17 And if reboot and return to normal Feb 06 16:40:36 Already separated power modem .. and the same Feb 06 16:41:08 I thought of bug lib with this part ... Feb 06 16:41:16 try attaching to the debug port to see what the kernel does Feb 06 16:42:15 CleitonBueno, I'm with tbr on this one -- from the sounds of it, you're not providing enough juice Feb 06 16:42:42 without hearing more, I'd find a beefier 5v supply. 2A (10W) at least Feb 06 16:43:22 I used 3.8 kernel and now 3.12 Feb 06 16:43:54 CleitonBueno: attach to the debug UART and capture kernel logs of a crash. Feb 06 16:44:41 But the modem power this separated from the BBB, we made another source for it Feb 06 16:45:03 CleitonBueno, you'll need a 3.3V usb -> ttl serial convert: e.g. http://www.adafruit.com/product/284 Feb 06 16:45:18 aka a "ftdi cable" or adaptor Feb 06 16:45:21 I advise something to debug deeper into the kernel regarding this? Feb 06 16:45:42 capture console output Feb 06 16:47:25 if/when the kernel crashes, your best chance for catching additional useful crash information is via the console. Feb 06 16:47:37 Without that, you're pretty much in the dark Feb 06 16:50:14 Perfect, I'll do this Kaak Feb 06 17:02:28 Beagle's flying with snappy http://erlerobotics.com/blog/erle-robotics-first-flight-ubuntu-core/ :)! Feb 06 17:02:54 :- Feb 06 17:02:59 :-D Feb 06 17:03:05 :) Feb 06 17:03:27 i'll put some time this weekend into the FS, will be happy to share the image if anyone wants it Feb 06 17:03:34 we'd also install ROS of course :) Feb 06 17:04:53 can you put it in docker or whatever the equivalent is? Feb 06 17:05:54 jkridner: you mean the whole image? Feb 06 17:06:27 vmayoral: nice work! Feb 06 17:42:11 jkridner: checking the GSOC Idea page : http://elinux.org/BeagleBoard/GSoC/Ideas Feb 06 17:42:59 it's basically like the one of last years, are all the ideas there still aplying for this year? Feb 06 17:43:48 need help updating it? Feb 06 20:28:41 Hi Everyone. Im a switcher from Raspberry Pi to BBB. Feb 06 20:45:42 Hmm. I am using a debian image for the beagle bone black. Can someone confirm that USB Host is horribly broken? Feb 06 20:45:57 is there a chance that this is better with the angstrom image? Feb 06 21:05:53 Like to throw a question out there?? Just Purchased the BBB and plugged into the USB on Win7pro, downloaded drivers they show installed but unable to go to 192.168.7.2 Feb 06 21:05:55 nomis, USB can certainly have issues -- much of it is driven by two factors: 1) The kernel you are running 2) The power supply you are using Feb 06 21:07:56 The kernel driver for `musb' (the host controller for the BBB) has had a alot of work aimed at making things better -- it has mostly been positive. Things are getting better Feb 06 21:08:52 as for your power supply, I've found that many under-deliver on their rated wattage -- make sure you are using one you trust to reliably deliver *at least* 1A Feb 06 21:09:02 2A would be better for breathing room Feb 06 21:17:22 KaaK: ah, power supply is a good point. Right now I am powering the BBB via USB itself. Feb 06 21:18:00 KaaK: the debian image seems to run 3.8.13 Feb 06 21:18:47 nomis, its unlikely to be a silver bullet, but it very well could be your issue. Especially if you're using a power-hungry USB device (HDD, Wifi, etc.) Feb 06 21:19:46 I haven't used 3.8.13 for some time now. Depending on your comfort level you might be interested in 3.14, or 3.19 available here: https://github.com/beagleboard/linux Feb 06 21:20:58 I'm running 3.19, and I've been very happy with USB stability. I'm not sure how much of the kernel USB work gets backported into 3.8 Feb 06 21:21:29 the usb device I use is a simple µC-Board that talks ttyACM Feb 06 21:22:32 KaaK: as I am doing linux kernel development for a living my comfort level is not that bad :) Feb 06 21:23:10 you can always run `dmesg` from a CLI on your BBB. You might have some more error-specific details there Feb 06 21:23:41 KaaK: that is weirdly nondescript. Feb 06 21:23:51 "CAUTION: musb: Babble Interrupt Occurred" Feb 06 21:23:59 ahh, the infamous babble Feb 06 21:24:54 Babble and VBus errors are probably the most common Feb 06 21:25:32 then unplugging the device doesn't make it disappear from the "lsusb" output Feb 06 21:25:58 so the usb phy doesn't seem to generate the appropriate interrupts. Feb 06 21:27:22 (that i've personally experienced). the `musb' host driver has had a ton of work that helps on both accounts. Its been awhile since I've last read into it, but I believe the babble issue centers around musb's handling of URBs Feb 06 21:27:49 I know that musb has made a lot of troubles on other platforms I've been using at work. Feb 06 21:27:54 *sigh* Feb 06 21:28:48 it is just a totally unexpected roadblock for the project I am working on at the moment... Feb 06 21:30:42 yeah, it is annoying. The bright side is that it is much better in newer kernel releases. Feb 06 21:32:01 I'd say dust off your cross-toolchain of choice and compile away. you can use the KBuild target `deb-pkg' to get a nice .deb to use when installing Feb 06 21:32:21 I believe you can also find them on the net in places, but I dont have any links on hand Feb 06 21:33:39 As for cross tools, Linaro is a good choice -- I personally use the arm-linux-gnueabihf toolchain out of this deb repo: http://emdebian.org/debian/ Feb 06 21:33:43 KaaK: bbb-support is in the vanilla kernel? Feb 06 21:34:00 KaaK: (I'd guess so) Feb 06 21:34:31 It is -- I personally prefer the vanilla kernel Feb 06 21:34:52 *nod* Feb 06 21:34:58 But that is mostly due to the awesome job the BBB kernel maintainers are doing to get things mainlined Feb 06 21:35:17 yeah. that is really worth praising. Feb 06 21:36:00 I find the work in the vanilla kernel (esspecially with the device trees) is much easier to grok. The work in the BBB fork is a bit more `in motion` Feb 06 21:37:04 im running vanilla 3.19.0-rc7 on 6 BBBs right now, and its been very stabil all around Feb 06 21:40:01 here is my current kernel config for 3.19.0-rc7: http://paste.ubuntu.com/10098257/ Feb 06 21:40:30 It's pretty fat -- it could use some trimming. But its a good starting spot, and is currently running on my hardware great Feb 06 21:43:13 KaaK: thanks, much appreciated Feb 06 21:43:46 nomis, no problem. good luck! Feb 06 23:32:10 are overlays available in mainline? Feb 06 23:32:58 (not that they're needed strictly speaking, but still nice for tinkering) **** ENDING LOGGING AT Sat Feb 07 02:59:59 2015
