**** BEGIN LOGGING AT Tue Mar 08 02:59:59 2016 Mar 08 03:42:06 oh lol, there are also PRU cores all over the Keystone devices, except they call them "PDSPs" Mar 08 03:56:42 wow, ks2 really has a ton of 'em... 8 in the queue manager, 15 in the packet accelerator, 3 in the security accelerator Mar 08 06:26:31 hi guys. i am back again with yesterday problem. Mar 08 06:26:42 Avahi is installed and is running on my BBB Mar 08 06:26:48 i can verify its status Mar 08 06:27:17 but i can connect to BBB via ethernet using ssh root@beaglebone.local Mar 08 07:54:29 If I use a 3.7 volt battery to run the beaglebone black, can I still get 5V over USB assuming enough amps? Or do I need to step up to 5V before powering the board? Mar 08 07:56:40 you'd need to check the schematic if VUSB is hooked up to a regulator Mar 08 07:59:24 I guess I also could just try it Mar 08 08:00:01 I was thinking about using a smartphone battery Mar 08 08:02:56 you won't get very far on a small battery though. I'm not sure how much power saving the board even can do Mar 08 08:06:11 wouldn't you have to up-vert the 3.7 first anyways? Mar 08 08:08:26 I think you can run the BBB from the 4-pin connector on a LiPoly, but there is no realy battery management and no charging Mar 08 08:08:39 I think part of that is even documented on the elinux wiki Mar 08 08:09:02 s/realy/real/ Mar 08 08:23:35 I was under the impression that you could charge the battery over the 4 pin Mar 08 08:25:26 the board has not been designed for full and proper battery operation Mar 08 08:27:07 http://elinux.org/BeagleBone_Power_Management Mar 08 08:27:59 so yes, you can actually destroy a BBB if you don't implement hw modifications Mar 08 08:42:28 thanks Mar 08 10:42:33 Is it possible to write a linux image to an SD card and boot from it and work solely from it? Not touching eMMC. Mar 08 10:42:42 or then mounting it as additional disk space Mar 08 10:43:21 I want this because when I flash the eMMC, the image takes almost all available space and leaves me with around 100MB Mar 08 10:43:37 this is now very nice, I want my system to reside on a 16GB SD card Mar 08 10:43:41 not* Mar 08 10:47:09 yes Mar 08 10:47:28 if you boot with the system button pressed it will boot from SD Mar 08 10:47:42 if you want that permanent, kill the "MLO" file on the emmc Mar 08 11:13:25 av500: so, after I kill the MLO file, I don't have to press the button next time? Mar 08 11:30:10 Good morning. I was here yesterday and got a bit of advice. But my BBB is still unresponsive. I bought a kit from Make over Amazon last week and been trying to boot the board ever since. By connecting the BBB to my computer only the power LED lights up. No USB device is mounted. I installed the drivers from the website to see if that will enable me to see the USB connection to the BBB. Mar 08 11:31:30 I then copied "BBB-eMMC-flasher-debian-8.3-lxqt-2gb-armhf-2016-02-26-2gb" to a micro SD and followed the instructions on Beagleboard.org to attempt flash the BBB. Mar 08 11:32:07 Nothing changed, just a solid blue power LED. Mar 08 11:34:18 Any help would be greatly appreciated. Mar 08 11:41:17 hi, I am doing image processing on linux using open cv. I am following the link of derek molloy: “http://derekmolloy.ie/beaglebone/beaglebone-video-capture-and-image-processing-on-embedded-linux-using-opencv/” when I execute the capture program. Not even a single frame is captured and I got “select timeout” error .i am googling it but did't find any solution for this. Mar 08 12:05:09 hi, I am doing image processing on linux using open cv.

Not even a single frame is captured and I got “select timeout” error .i am googling it but did'nt find any solution for this. Mar 08 12:35:16 Hey! Is there a way i could compile a single module ( namely virtio_rpmsg_bus) on my BBB ? Mar 08 12:36:08 also, my root mounted fs I showing as 90% full. Is that normal ? Do I have a lot of useless things there ? Mar 08 12:38:44 ZeekHuge: depends on your starting point. the console-only images leave quite a bit more free space Mar 08 12:39:11 ZeekHuge: and kernel module compilation implies that you have the full toolchain and probably also kernel sources on it. Mar 08 12:39:43 The toolchain is there on the BBB and my laptop. Mar 08 12:40:09 but, If I am cross-compiling the module, its not being loaded up by modprobe. Mar 08 12:40:41 I guess compiling the module locally would make it right. What do you think about it LetoThe2nd ? Mar 08 12:40:42 ZeekHuge: i'd say, let yourself be inspired by http://derekmolloy.ie/writing-a-linux-kernel-module-part-1-introduction/ Mar 08 12:47:00 Thanks LetoThe2nd ! but how can i get the source for the single module from kernel tree ? Mar 08 12:47:27 will just downloading that directory do that ? Mar 08 12:48:01 Also, I think I'll have to write a different Makefile for that. Mar 08 12:53:22 ZeekHuge: i doubt that ripping something out will instantly work easily Mar 08 12:53:57 yeah, so what would you suggest ? Mar 08 12:54:07 getting the full tree. Mar 08 12:54:25 its 90% full. There's no space for it. Mar 08 12:54:33 on your dev host, then completely rebuild the kernel you want/need Mar 08 12:54:38 infact not even for the current version. Mar 08 12:55:04 but thats just my opinion, i'm sure others are valid too. Mar 08 12:55:43 yeah, Thank you :) Please tell me if you get any other idea for that, while you are here :) Mar 08 13:00:39 do a proper rebuild of your fs, using OE Mar 08 13:00:40 ZeekHuge: you need the whole kernel source tree Mar 08 13:00:54 either on your laptop or on the BBB Mar 08 13:00:58 to compile a module Mar 08 13:01:08 I have it on my laptop. Mar 08 13:01:24 the cross compile Mar 08 13:01:27 it has been done before Mar 08 13:01:30 countless times Mar 08 13:02:04 this is what /var/log/messages says : virtio_rpmsg_bus: disagrees about version of symbol module_layout Mar 08 13:02:15 when I insmod the cross-compiled module Mar 08 13:02:32 av500: with all that funny module signing of distro kernels... those countless times are becoming countlessly annyoing! Mar 08 13:02:36 then your kernel on laptop and BBB do not match Mar 08 13:02:48 LetoThe2nd: indeed Mar 08 13:02:59 yes, so how can i get the exact same kernel source ? Mar 08 13:03:18 bbb uname -r is : 4.1.17-ti-rt-r48 Mar 08 13:03:25 ti???? Mar 08 13:03:33 rt? Mar 08 13:03:55 ZeekHuge: its not only the source, its also the same toolchain and some other small things. and your uname sounds like are in for a lot of pain. Mar 08 13:04:03 ah Mar 08 13:04:05 rcn Mar 08 13:04:08 https://github.com/beagleboard/linux/releases/tag/4.1.17-ti-rt-r48 Mar 08 13:04:17 LetoThe2nd: its rcn releases Mar 08 13:04:19 it seems Mar 08 13:04:26 av500: like i said. pain. Mar 08 13:04:26 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot_lxqt Mar 08 13:04:35 *SCNR* Mar 08 13:04:48 ZeekHuge: no, thats 49 Mar 08 13:05:14 see https://github.com/beagleboard/linux/releases/tag/4.1.17-ti-rt-r48 Mar 08 13:05:16 for 48 Mar 08 13:05:22 that should give you the correct source Mar 08 13:18:57 wheres the log ? of the current session ? :) Mar 08 13:23:52 in ~/.logs/ Mar 08 13:23:59 at least for me Mar 08 13:24:28 is there a way to unclaim device and gpio mux a cape did and reuse those pins then ? Mar 08 14:19:56 i'm looking for a single board computer with the capability of booting from an internal (possibly read-only) emmc or similar and still allow pluggin in an sd card to write data to Mar 08 14:20:35 does the beagle bone black support this? from the pdf manual i found it seems it supports both media, but is booting from internal memory possible when an sd card is plugged in? Mar 08 14:29:56 Guest62352: yup Mar 08 14:49:45 hello guys i have difficulty while browsing to my beagle bone Mar 08 14:51:11 im using beagle bone rev A6a Mar 08 14:51:27 it has debian jessie latest dist on it Mar 08 14:51:34 and my os is ubuntu 15 Mar 08 14:51:45 when i connect it via usb Mar 08 14:51:57 it goes green for the first check Mar 08 14:52:23 but it takes ages before i see green for the second and third checks Mar 08 14:52:42 so i think it can be a problem about drivers Mar 08 14:52:55 and i tried running mkudevrule.sh several times Mar 08 14:53:08 but it has changed nothing Mar 08 14:53:15 do you have an idea Mar 08 14:55:57 any ideas? Mar 08 15:18:02 Hi, I am new to Bonescript. I have a quesiton regarding I2C with Bonescript. Mar 08 15:20:58 testing Mar 08 15:41:52 hi Mar 08 15:43:29 I've got problem with beaglebone rev. b: http://pastebin.com/4RHZnQQd Mar 08 15:43:51 after that the board goes off Mar 08 16:32:38 Hey ! I am trying to get PRU-framework working on my BBB Mar 08 16:33:03 so this is the dmesg from my bbb : http://paste.debian.net/411927/ Mar 08 16:33:16 and comparing this to : https://gist.github.com/shubhi1407/1ee6927f16b4c3664601 Mar 08 16:33:36 I think that the problem is with virtio_rpmsg_bus Mar 08 16:34:08 would compiling the virtio_rpmsg_bus help ? Mar 08 16:35:19 also, while making PRU-framework, some headers had error, so I replaced them with headers from this repo :https://github.com/pantoniou/testpru Mar 08 16:59:11 . Mar 08 17:01:04 hi againi Mar 08 17:01:21 anyone using beaglebone reva6a with debian jessie? Mar 08 18:56:08 i am using the latest debian 8.3 image on beaglebone black rev c Mar 08 18:56:28 i am trying to change the IP to static Mar 08 18:56:35 but it is not working Mar 08 19:32:50 pk: IP for what? Mar 08 19:38:06 I have 2 Element14 BeagleBone Blacks that claim to be Rev C. The stamp on the boards shows PCB Rev B6. Does this signify that they are Rev B boards, not C? Mar 08 19:40:12 The documents that came with the boards claim they are Rev C. How can you verify that they are? Mar 08 19:40:56 ignore what's on the pcb under the power dc jack .. check the sticker with the serial # Mar 08 19:41:17 on P8 on my board Mar 08 19:42:34 hi guys Mar 08 19:42:48 i have trouble while browsing to my board Mar 08 19:43:04 im using beagle bone rev A6a with debian 7.9 Mar 08 19:43:15 and my os is Ubuntu 15 Mar 08 19:44:33 has anyone faced such a problem Mar 08 19:44:34 ? Mar 08 19:44:55 i have tried reinstalling latest images over 4 times Mar 08 19:47:55 On the Element14 BB, they do not have the rev on the P8 header, just a number and QC sticker. Mar 08 19:52:43 i want to change the IP of the board to static ip address instead of dynamic Mar 08 20:38:51 What causes the BeagleBone Black to fail to write eMMC? I have tried the newer recommended Debian images as well as the older Angstrom distribution images on beagleboard.org/latest-images and in all cases after the 20 minute or so cylon-like LED pattern the LEDs all blink with the heartbeat. I can boot from the MicroSD card, but I am unable to install Linux on the eMMC. Mar 08 20:42:22 I have tried googling this issue, but I have not found any instructions on what to do if you can not get the eMMC to write correctly Mar 08 20:43:08 do you have a rev C beaglebone? Mar 08 20:43:21 How can you tell what revision your board is? Mar 08 20:43:57 The eMMC has the text "2YAI8 JW896" written on it Mar 08 20:44:02 if that means anything Mar 08 20:45:19 So the short answer is that I don't know what revision I have Mar 08 20:45:23 https://www.micron.com/support/fbga?fbga=JW896 Mar 08 20:45:33 that's a 2G flash, which means you have older than rev C Mar 08 20:45:41 make sure you don't try to flash a 4GB image, since that won't fit Mar 08 20:46:13 is there a place to download the smaller images? Mar 08 20:46:30 looking at what I have been trying to write I see that the file is larger than 2GB Mar 08 20:46:38 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot_lxqt <-- that has both 4gb and 2gb images Mar 08 20:47:43 I will give that a try Mar 08 20:47:45 thank you Mar 08 20:48:14 and I would have expected the iot (= non-GUI) images to be 2gb also, except for some inexplicable reason rcn made them 4gb Mar 08 20:49:25 I still need to poke him about that Mar 08 20:49:39 anyway, I'm afk Mar 08 21:07:17 That was the problem. Linux is now booting from the eMMC. Thanks a bunch. **** ENDING LOGGING AT Wed Mar 09 02:59:58 2016
