**** BEGIN LOGGING AT Fri Sep 05 02:59:59 2014 Sep 05 03:05:56 Hi Guys, Jason here. I have a question on the BeagleBone Black board. The BOM shows BBB DDR3 Ram is 1.35V part but the schematic says 1.5V. Can anyone verify what voltage the DDR3 is really running? Sep 05 03:11:31 check the srm? Sep 05 03:12:05 The DDR3L memory device and the DDR3 rails on the processor are supplied by the Sep 05 03:12:06 TPS65217C. Default voltage is 1.5V but can be scaled down to 1.35V if desired Sep 05 03:12:08 as per the srm Sep 05 03:16:38 Thank you. Yes, I realize it could be controlled by the Power Managment IC (PMIC) and could be set to 1.5V or 1.35V. Mostly I was curious about the default setting. I realize this depends on software. Forgive me, but what is SRM? Sep 05 03:21:30 system reference manual Sep 05 04:21:54 ; Sep 05 05:04:01 good morning I'm having trouble wit my bbb. Since yesterday it does not start correctly. It boots fully, my userspace program runs, but no cape overlays are loaded and I have no Ethernet access. Furthermore I cannot send strings to serial debug console, just read out the outputs. Here is my boot log: http://pastebin.com/G9pZBzvh Sep 05 05:04:59 What could be the problem is reading this line: "*** Warning - readenv() failed, using default environment" but what does it mean and how to solve it? Sep 05 05:05:27 that should be fine Sep 05 05:05:40 the BBB doesn't have onboard environment memory Sep 05 05:05:45 ok Sep 05 05:05:46 (for u-boot) Sep 05 05:08:42 hrm, I just attatched an usb keyboard but this is also not recognized. strange... Sep 05 05:09:51 what else can I do to check what's goin wrong. Sep 05 05:19:22 I removed the sdcard from bbb an attached it to my pc. fsck does show no errors for all of my partitions on the sd Sep 05 05:59:20 hi Sep 05 06:00:50 looking for wifi that i can get access to the mac directly or even the phy Sep 05 06:01:30 plugs into a bb black Sep 05 08:44:33 hello Sep 05 08:44:59 i have a problem powering up my beaglebone black from usb Sep 05 08:45:10 i need help Sep 05 08:47:20 what is your problem? Sep 05 08:47:29 hi Sep 05 08:47:47 i am unable to power up my beaglebone black with the usb cable Sep 05 08:47:59 no led light comes up at all Sep 05 08:48:42 did it work before? Sep 05 08:48:47 yes Sep 05 08:48:58 what was the last thing you did or attached? Sep 05 08:49:24 i was running a blinking led code and all of a sudden everything went off Sep 05 08:50:06 the USB port is still working? Sep 05 08:50:12 no Sep 05 08:50:21 pc does not recognize it Sep 05 08:50:42 so then your PC usb port is broken Sep 05 08:50:44 i am able to power it via te 5v dc port and connect to pc with ethernet port Sep 05 08:52:40 does your usb port work with other devices? Sep 05 08:58:07 * tbr suspects he found out that plugging it into a different port helps Sep 05 09:14:19 george__: please keep it here, private messages are not necessary Sep 05 09:14:41 ok Sep 05 09:14:53 like i was saying Sep 05 09:15:19 i am able to power up my board with the 5v dc port but not with the usb cable Sep 05 09:15:32 08:52:40<@av500> does your usb port work with other devices? Sep 05 09:16:21 yes Sep 05 09:16:38 everything i have plugged in so far works Sep 05 09:17:01 have you tried the USB cable on a different device? Sep 05 09:17:08 yes Sep 05 09:17:13 maybe the usb on the BBB is broken then Sep 05 09:17:24 check the connector closely Sep 05 09:18:18 the connector looks intact Sep 05 09:31:38 does the PC see the BBB if you power it over the barrel connector but have the USB cable connected? Sep 05 09:38:36 Hi everyone Sep 05 09:38:53 Quick question: Is it possible to use OpenGL ES on Linux without X11? Sep 05 09:39:17 I'd like to make a fullscreen 3D app, so I'm not interested in the windowing/remote features of X Sep 05 09:39:51 sure Sep 05 09:40:07 its all SWE Sep 05 09:40:09 SW Sep 05 09:41:08 av500: you sure its SW? Sep 05 09:42:32 hi everyone i wanna ask something about beaglebone black, i bought beaglebone black, but why it wont work when plug in a power from adaptor 5v 1,2A ? but when i use mini usb as a power it work Sep 05 09:43:15 it should work Sep 05 09:43:18 check the voltage Sep 05 09:43:20 polarity Sep 05 09:45:12 no Sep 05 09:45:12 Fathan: you have an issue with your power adapter. It's either broken, or plugged in reverse Sep 05 09:45:28 (Because 5V 1.2A should be just fine) Sep 05 09:46:20 @tbr -- it powers off when i plug in the usb cable after powering it with the barell connector Sep 05 09:47:32 george__: sounds like for some reason that is damaged then. Sep 05 09:47:50 george__: think again what you did with the board that could have caused this Sep 05 11:32:33 for i2c on the latest debian, "i2cdetect -r 0" is the internal i2c bus, and "i2cdetect -r 1" is the id sd bus? Sep 05 11:33:03 how do i enable i2c on pins 17 and 18 Sep 05 12:04:00 hi Sep 05 12:04:04 hi Sep 05 12:05:02 i'm have problems at beaglebone black Sep 05 12:05:46 in how to use i2c and SPI i/o Sep 05 12:09:16 hi guys anyone can help me? Sep 05 12:09:42 Tem algum Br nessa parada porque eu to precisando de ajuda mas ta foda Sep 05 12:39:16 hello Sep 05 12:39:30 can so help me with mail? Sep 05 12:42:54 hello everyone, i think there something wrong with my BBB, i plug the power from adaptor and BBB not work, but when i connect use usb its work, and im trying to connect to monitor with hdmi, but there is nothing hhappen with the monitor, Sep 05 12:50:12 fathan: what sort of power supply is that? Sep 05 12:53:57 power supply from usb connection with computer Sep 05 12:57:54 fathan: if you want to use a power supply, then it needs to be 5V and at least 2A and the cable must use the barrel connector Sep 05 14:12:44 so other than spending upwards of 30-60 on a motorcape is there anything you guys can suggest for motor control? Sep 05 14:29:49 mistawright: Making your own motor-driver cape? Sep 05 14:30:16 may end up having to do that Sep 05 14:30:55 Or, use an offboard driver and connect to it by flying leads. Sep 05 14:31:17 Or get a fancy USB or Ethernet offboard driver and connect over those. Sep 05 14:31:22 Or... Sep 05 14:31:32 (you probably get my point by now) Sep 05 14:39:30 rcn-ee: I am able to boot Debian off of the microSD without a problem. Using your init-eMMC-flasher-v2.sh with the patch you sent me last week (http://pastebin.com/fNzuzqnP) the file system and kernel seem to be copied to the eMMC just fine. But when I try to boot to the eMMC with the microSD not inserted, it gives up and drops to an (initramfs) shell. Sep 05 14:40:50 I'm pretty sure this is because /proc/cmdline contains root=/dev/mmcblk1p2 and mmcblk1 does not exist when the microSD is not inserted. But I can't figure out how this is generated or how to change it to mmcblk0. Sep 05 14:41:54 embedded_kyle, i use an initrd for that, then we just use the UUID label for eMMC.. Sep 05 14:42:35 the script should have generated /boot/initrd.img-`uname -r` and copied that to the eMMC... Sep 05 14:43:41 There was an initrd.img on the eMMC but you had told me to run update-initramfs and copy it over manually. Which I did. Sep 05 14:43:55 I have the UUID set in my fstab and my uEnv.txt but it doesn't seem to be being used. Sep 05 14:44:57 humm, must have been an older bootloader installed, the new "uuid=" variable is new as of july.. try setting: "mmcroot=UUID=xyz" Sep 05 14:46:21 side note, i've added a debug hint to u-boot, right before it calls "bootz xyz - xyz" it'll dump the current "bootargs" so it's easier to debug this.. Sep 05 14:47:46 greetings, I'm not sure if this is appropiate but is it possible to root android BBB? The app I'm developing most definitely needs to access the system on a root level. Sep 05 14:48:03 Um. Sep 05 14:48:20 THe Android you have on your bone will be rooted pretty much by definition. Sep 05 14:48:27 Because *you* installed it there. Sep 05 14:48:55 I have a terminal installed and a "rooted" file manager but I can't get into the system folders. Sep 05 14:49:29 my android tablet is fully rooted and I have total access to everything. Sep 05 14:49:31 Why noit? Sep 05 14:50:24 the system tells me "not alloed to su" Sep 05 14:50:29 allowed Sep 05 14:50:50 Interesting. Sep 05 14:50:58 WHere did you get the image you are running from? Sep 05 14:51:23 one second, let me confirm................... Sep 05 14:52:31 Prebuilt-JB-Chipsee-BBB-EXP-20140104.tar.gz Sep 05 14:54:08 I need to be able to ssh into BBB with full root access. ADB won't help me as I need this access from my apps. Sep 05 14:54:20 I have no idea what that is, but I suggest talking with the people who made it to get root. Sep 05 14:54:42 That is also a pretty old image. Sep 05 14:55:11 it came on the cd. where can I get a newer one? Sep 05 15:01:28 rcn-ee: Board is a Rev A6A but I've since updated the bootloader to U-Boot 2014.07-dirty (Aug 28 2014 - 17:00:26). and I already had the line you mentioned in my uEnv.txt. Sep 05 15:01:51 Here is a boot with the microSD in: http://pastebin.com/cUMvQTUY which works great. Sep 05 15:02:06 Here is a boot with the microSD out: http://pastebin.com/EUYiztaC Sep 05 15:02:54 The mess of gibberish characters before the shell happens approximately 75% of the time. Not sure if it's meaningful. Sep 05 15:04:17 yeah, uboot should be replacing root=/dev/mmcblk1p2 with root=UUID=actual uuid.. Sep 05 15:08:37 iomari: ...CD? Sep 05 15:10:08 Is that functionality part of base uboot? Or part of your patch? And I used the am335x_evm_config. Should I have used the am335x_boneblack_config instead? Sep 05 15:11:23 agmlego, yes Sep 05 15:12:22 I;ve seen the one cd where I found the images for linux and windows. But my partner said he got the android image from a cd which he can't find now. Sep 05 15:12:51 It has images fopr android 4.1 and 4.2 Sep 05 15:12:59 s/fopr/for Sep 05 15:13:47 embedded_kyle, it's in my patch: https://github.com/eewiki/u-boot-patches/blob/master/v2014.07/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch#L273 Sep 05 15:17:57 Hmm...Even when it boots with the microSD in it still uses the /dev name instead of the UUID. I'm going to recompile uboot from scratch using am335x_boneblack_config and see where that gets me. Sep 05 15:35:59 so #beaglepilot is dead and i luckily stumbled across a video of a beaglebone black in flight using beaglepilot on youtube that was uploaded this month. With that being said can I start trying to fly with my beaglebone black? Sep 05 15:49:01 * jkridner looks around for Anuj or Victor and doesn't see them Sep 05 15:49:59 mistawright: they have a Google Group: https://groups.google.com/forum/#!forum/beaglepilot Sep 05 15:50:25 looks like they moved to https://groups.google.com/forum/?hl=en#!forum/drones-discuss Sep 05 15:52:08 jkridner: hi, how is your c55x? :) Sep 05 15:52:21 av500: rusty. Sep 05 15:52:31 used to do c55x assembly every day.... Sep 05 15:52:37 that's been more than a decade. Sep 05 15:52:45 well, assembly + C Sep 05 15:52:51 coworker is reverse engineering some synth Sep 05 15:52:52 why? Sep 05 15:52:59 and lo and behold, its C55x :) Sep 05 15:53:39 I'm curious. I have some friends who've done it more recently than me. Sep 05 15:54:26 have it disassembled already? Sep 05 15:54:54 he just started Sep 05 15:55:06 I pointed him to some of our toolchains Sep 05 15:55:09 from omap1 times Sep 05 15:56:08 jkridner: http://blog.rona.fr/post/2014/09/04/Inside-a-KORG-Kaossilator-Pro Sep 05 15:57:58 @mistawright we have come a long way in the development of beagle pilot and it is definitely not dead. Sep 05 16:00:52 we use different mode of communication that is Skype as it is used by ardupilot developers with whom we are closely working. You can also find blog posts on our progress @ diydrones.com Sep 05 16:01:06 jkridner: hi, we are ready to start if you are. Sep 05 16:01:25 rolando07: I'm still pulling up the latest version of pruspeak. Sep 05 16:02:00 av500: ah, the skillful mister rona :) Sep 05 16:02:09 rolando07: want to do a google hangout on air (ie., recorded)? Sep 05 16:02:18 jkridner : here Sep 05 16:02:36 jkridner: sure, we are ready to do that Sep 05 16:02:58 tbr: indeed Sep 05 16:02:59 karki: rolando07 is a student at JBU who will be looking to extend the work of lucas to put the Arduino libraries on PRU and integrating with your pruspeak interpreter. Sep 05 16:03:43 cool! Sep 05 16:04:46 I'm working on creating a very simple pru.serial api Sep 05 16:05:06 for communication b/w linux userspace and pru Sep 05 16:05:31 so this could emulate arduino's Serial library Sep 05 16:07:02 rolando07 : you working with somebody? Sep 05 16:07:07 rolando07: I started the hangout... need to know what IDs to invite. Sep 05 16:07:48 karki: yes, a classmate Sep 05 16:07:50 rolando07: https://plus.google.com/u/0/events/c38n0bj06ba12cd1tqtdsiij4ig Sep 05 16:08:12 send a chat to jkridner on G+ to get invited. Sep 05 16:09:34 karki: can you hop on and help me get the demo running? Sep 05 16:11:28 karki, rolando07: did you get my invites? Sep 05 16:12:02 jkridner: yes, it says that the video broadcast will start soon. Sep 05 16:12:15 you should look for a different invite... Sep 05 16:12:37 rolando07: was the broadcast announcement... you should have also gotten a request to join the chat. Sep 05 16:14:05 rolando07: are you logged in as this user: https://plus.google.com/105474302865733473925/posts ? Sep 05 16:14:25 jkridner: yes Sep 05 16:15:09 rolando07: should Karl Anderson be invited? Sep 05 16:20:39 jkridner : will join back in a min Sep 05 16:20:44 browser crash Sep 05 16:20:49 :( Sep 05 16:38:00 rolando07 : sorry about the bad internet connection :/ I'll watch the hangouts on you tube later! Sep 05 16:56:56 karki_: https://www.youtube.com/watch?v=VPSqb15twY4 Sep 05 19:29:25 rcn-ee: I've rebuild uboot using both am335x_evm_config and am335x_boneblack_config. But it still drops to an (initramfs) shell when booting using only the eMMC with no microSD and /proc/cmdline still has root=/dev/mmcblk1p2 Sep 05 19:30:11 Here is the state of the system directly after running init-eMMC-flasher-v2.sh followed by my creating and copying the initrd: http://pastebin.com/TK12XPJw Sep 05 19:30:31 Any ideas on what would be preventing uboot from using the UUID? Sep 05 19:31:36 embedded_kyle, echo "uuid=99652596-c7f0-4018-94a0-b3834fa78d3b" >> /boot/uEnv.txt Sep 05 19:32:34 uboot doesn't know about uuid as far as I know, but it will pass whatever argument you give it to the kernel Sep 05 19:33:00 So that line should be below the mmcroot=UUID=xyz? Sep 05 19:33:03 it does when he's running my patch. ;) Sep 05 19:33:14 ah... nice Sep 05 19:33:15 i'd just remove the mmcroot line.. Sep 05 19:33:50 in my last build, it'll actually say it's using it too.. ;) Sep 05 19:35:24 Hi folks - I have a quick question on forcing an init script to run absolutely last Sep 05 19:36:46 <_av500_> after the heat death of the universe? Sep 05 19:37:12 lol Sep 05 19:37:18 Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux Debian 7.5 Sep 05 19:37:29 diakonos, https://wiki.debian.org/LSBInitScripts Sep 05 19:37:38 Required-Start: Sep 05 19:37:46 I've tried LSB Required-Start of $all Sep 05 19:38:07 but the problem I'm running into is that other scripts require $all as well Sep 05 19:38:17 and I can't force my script to run absolutely last Sep 05 19:39:01 force it to run "after" all $all (depends) Sep 05 19:39:35 throws an error when adding in additional scripts that depend on $all Sep 05 19:39:51 add a sleep 10 at the start? Sep 05 19:40:08 added sleep for 300 - still no dice Sep 05 19:40:26 is there anything that runs after init scripts? Sep 05 19:40:34 in wheezy, debian was converted to a dependency like sysv, so they made it "really" hard to setup order like that.. Sep 05 19:41:21 rc.local? Sep 05 19:41:26 the only thing that has worked for me so far is to run a cron using @reboot Sep 05 19:42:24 but that only enables me to run it once Sep 05 19:42:28 good point tbr .. Sep 05 19:42:58 diakonos: have you tried /etc/rc.local yet? Sep 05 19:43:10 I have not Sep 05 19:43:15 rcn-ee: That got it! After removing mmcroot= I am good to go. Thanks! Sep 05 19:43:15 I will try that Sep 05 19:46:48 here's another question for the group: is anyone using the Adafruit BBIO library for python? Sep 05 19:47:07 Yes. Sep 05 19:47:59 do you know if there is a GPIO.getStatus() or something of the sort? Sep 05 19:48:05 diakonos: https://github.com/i3detroit/i3Twitterbot and https://github.com/i3detroit/PartsLaser use it, or will. Sep 05 19:48:10 diakonos: Eh? Sep 05 19:49:00 Oh, it appears that I am using alexanderhiam's PyBBIO for those, not Adafruit's. Sep 05 19:49:15 what do you recommend? ... Sep 05 19:49:40 I am not sure what you are asking, so... Sep 05 19:50:19 sorry - should have been more clear. What python library would you recommend for BBB Sep 05 19:51:14 Well, as I said, I appear to be using alexanderhiam's PyBBIO. No idea how that relates to Adafruit's; I suspect they are the same base and one is a fork of the other. Sep 05 19:51:47 And yes, the gpio has a .pinState() method that shows whether it is an input or output. Sep 05 19:52:26 great! Sep 05 19:52:30 thanks! Sep 05 19:57:16 Well, technically, pinState() returns None if it is an output, and returns digitalRead() if it is an input. Sep 05 19:57:19 But whatever. Sep 05 19:57:52 Since digitalRead() returns a 1 or a 0, you can be pretty certain. Sep 05 21:46:45 hi everyone, i heard that there's some people interested in BeaglePilot, feel free to reach me for more information Sep 05 21:47:06 i'd been moving myself to a new location so it took a while to settle down but should be fine from now on Sep 05 21:47:15 we recently had the first flight with a copter Sep 05 21:48:23 hi .. I am looking for sources for beaglebone black Sep 05 21:48:34 kernel 3.8.x Sep 05 21:48:54 can any one share the links to it.. Sep 05 21:49:21 Simba_, https://github.com/beagleboard/linux Sep 05 21:49:54 i intend to build on local machine and boot the bbb Sep 05 21:50:03 it's should be poddible right? Sep 05 21:50:55 possible.. Sep 05 21:51:11 and does this have active community support.. Sep 05 21:52:03 support as in answering questions Sep 05 21:52:25 on a friday afternoon? most of the community is heading to the bar, or getting ready. ;) Sep 05 21:52:33 :-) Sep 05 21:52:43 gotch Sep 05 21:53:01 checkout the mainline list: beagleboard@googlegroup.com Sep 05 21:53:02 thanks rcn-ee Sep 05 21:53:21 catch you guys later once the build is done.. Sep 05 21:53:25 otherwise, yes the kernel is "cross buildable" & "native buidlable"... Sep 05 21:53:44 ok.. thanks a lot that should get me started.. Sep 05 23:52:22 Saludos a todos Sep 05 23:52:54 alguien habla espaƱol? Sep 06 01:32:27 hi Sep 06 01:32:37 can someone help me please?

Sep 06 02:52:10 did you download the image that actually flashes the eemc? Sep 06 02:52:43 i have the following image : BBB-eMMC-flasher-ubuntu-14.04-console-armhf-2014-07-06-2gb Sep 06 02:53:28 without the sd card the boards works in ubuntu in command mode Sep 06 02:53:58 looks like you're flashing the eMMC Sep 06 02:54:01 that takes along time Sep 06 02:54:52 when I flash my eMMC, I let it run over night Sep 06 02:55:01 tutorials I've found say it takes 45 min Sep 06 02:55:07 but It took me 15 minutes Sep 06 02:55:07 I think it takes longer Sep 06 02:55:12 may be 20 Sep 06 02:55:25 the image is flashed, thats not an issue Sep 06 02:55:38 i want to run the board from sd card so that i can install GNOME Sep 06 02:56:16 The tutorials say, press the user button till 2 lights flash on board and then leave the button and the board will boot from sd card Sep 06 02:56:39 but in my case, it never boots from sd card ... it starts to flash the image again from sd card Sep 06 02:58:06 the image you have sounds like a flasher image Sep 06 02:58:14 so it's doing what it's made to do Sep 06 02:58:30 if you just want to boot off of sd, you probably need an image made for that Sep 06 02:58:40 yes Sep 06 02:58:54 you need to download the image that is not made to flash the bbb Sep 06 02:59:25 do you have a link handy for ubuntu image? **** ENDING LOGGING AT Sat Sep 06 02:59:59 2014
