    nice post~!
     
    I have tried this , using TI sdk builld  image. But I can't locate my VFS.
     
    I've tried /dev/mmcblk1p1, /dev/mmcblk1p2, /dev/sda2 . It's not working.
     
    What's wrong with the uEnv.txt  parameters.
     
    The following is my booting log message.

    exemaspilasem reacted to wt9s in No shutdown or reboot with Debian on BBB   
    Hi,
     
    I'm new to the BBB but have some prior Linux experience. Since I got my BBB last week I've played around with several distros and the one I like the best so far is the Debian, which I got from here:
     
    http://beagleboard.org/latest-images
     
    The only problem I'm having with it is that shutdown and reboot do not work. If I issue the the shutdown -h now command, it sends the message to whatever terminals are connected, but then nothing happens. Examining /var/log/messages I find this line right after the shutdown command is logged:
     beaglebone systemd-initctl[3125]: Received environment initctl request. This is not implemented in systemd. I've done some googling and found lots of reports of people having this same issue in older releases of Debian, mostly on PCs, but I couldn't find anyone that ever solved it.
     
    Has anyone else seen this, and does anyone have a clue how I can fix it? How long can I get away with just yanking the power before the eMMC is corrupted beyond use?
     
    Thanks,
     
    Jay

    OK, I'm pretty new to the BBB and my background is in programming not electronics.  I would really like to setup the BBB as a robotic arm controller.  The arm I'm looking at is the Lynxmotion AL5D 4 Degrees of Freedom Robotic Arm.
     
    http://www.robotshop.com/en/lynxmotion-al5d-robot-arm-combo-kit-4-dof.html#Multimedia
     
    Is the BBB capable of controlling this 4-axis robot?  I would assume I need a cape to do this but can't determine if an existing one would work.
     
    Any guidance would be appreciated.

    @@bluehash, and anyone else reading this blog of mine. As of this moment this will only work for ARCH debian and some custom busybox that a guy on the google groups did. He told me that Ubuntu, Angstrom, and Fedora all fail. So there is something different, I just do not know what it is.
     
    This person also says it fails after the kernel loads, and right after the rootfs finishes it's thing. SO I am half guessing that something like connman is messing things up. Just a guess though, this person ( Micha ) seems to think its the kernel module for these variations. But in this context Linux should be Linux . . .*stumped*

    err this is for the netboot instructions of mine. So yeah should not apply, but might.

    Hi All,
    I have bought beaglebone black and used tutorials to setup it. I started with start.html (provided with BBB). installed rules(mkudevrule.sh). Tried opening 192.168.7.2 in browser but didn't succeded. I tried finding IP of BBB using arp-scan and again got nothing. I found somewhere that by default ssh doesn't work on angstrom so i flashed debian into an SD card and booted with that ( i refer this tute:http://avedo.net/653/flashing-ubuntu-13-04-or-debian-wheezy-to-the-beaglebone-black-emmc/), again i am not able to connect with BBB. In start.html there's a link for USB to virtual Ethernet. I don't know how would i install this (if i need to)
    My system is detail is
    kumar@anandlinux:~$ uname -a
    Linux anandlinux.com 3.2.0-52-generic #78-Ubuntu SMP Fri Jul 26 16:21:44 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
    One of my friend suggested that i should use FTDI to USB cable to connect with BBB USB mini to USB won't work. Is that true? Currently i'm using USB Mini to USB.
    I tried using screen command too
    screen /dev/ttyUSB1 115200 but that too doesn't help.
    Please suggest how can i connect. I've been Googling since 5th march and still clueless.
    i tried flashig and using latest image(debian) from http://beagleboard.org/latest-images as well but that isn't working as well.
     
    Do i need to have any module like g_eather installed to access BBB?
    Please let me know if i need to install anything else.
    I'm using this forum for first time so if i used wrong topic/specific topic etc then let me know

    There are a few other camera capes(not as good as the pi one), including the Logitech 920, but am also looking into the future in case we need to go into production.

    When I do ifconfig, only lo shows, no eth at all. ifup eth0 doesn't work either and errors out. I tried a wifi dongle but it doesn't work either, no lights or anything. The usb hub is self powered as well so I know it is getting enough power.

    I have since changed "rw,async" to "defaults", Really I am not sure if the settings I had set had to do with this, but I will run with the default settings to see if I get the same error later. Hopefully, it is not my drive . . .

    ping 192.168.7.1 -> 20 packets sent, 0 received, 100% loss

    Always packets are sent but received is zero always

    Ps - I see this step in Derek Molloy's Beaglebone- Getting Started - Windows USB Network Adapter Setup Tutorial. Cant go ahead, I am stuck. He mentions the PC appears as 192.168.7.1 on network and BBB is 192.168.7.2
    But when I try myself, zero packets are received

    Can anyone debug this problem?

    Hi everyone, I received a BeagleBone Black a few weeks ago and have some questions about it.
     
    I'm trying to make a alarm clock, where the user can set various times to set off alarms. The alarms will be added to a priority queue, and a audio file will be played for each entry at the corresponding time. I also need access to the internet so I can get alarm times from a webpage or file. Later on I would also like to add some buttons and a LCD. 
     
    This is my first project with a device such as a BBB. I know C and a bit of C++. I also installed Ubuntu on a separate laptop and learned a few terminal commands. 
     
    My problem is that i'm not sure how to code an accurate clock and set up the alarms. Is it possible to do this at user space where the coding will be a bit easier? Or do I look into bare-metal programming?
     
    I played a bit with crontab, but it seems strange to me. I added 2 commands. I play an audio file at a certain time, and open xclock in the next minute. The audio only plays when i have a * for minute. And the clock application never opens.
     
    Any advice and/or guidance would be appreciated!

    Thanks Bluehash. One thing that is causing me to scratch my head though. All the typo's and misspellings I corrected with spell checking crept back in . . . No idea how that works lol.
