[beagleboard] Re: Missing packages in Ubuntu 13.04 on BeagleBone Black
Rick, I myself have tried many versions of Ubuntu image over BBBlack and I suggest not to use Ubuntu but use Debian since it already consists of it, there are some problems out of which the most prominent problem seems to be of X display , no matter what all is tweaked it still shows a blank screen for many! If destined to use Ubuntu anyway then I would suggest using Ubuntu 12 image, I got the Desktop with it and was perfectly able to use the VNC server and client to access it remotely! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BeagleBone driver issues with OSX Mavericks?

[beagleboard] Kernel/distribution advice for running BB XM with Camera, OpenCV, and networking
Hello, After months of working with the BeagleBone Black and OpenCV + v4l2, I'm trying to move our OpenCV work over to the BeagleBoard xM platform and take advantage of the direct camera interface port with a Leopard Imaging LI-5M03 camera (instead of the USB cameras we've been using with the BBB) to hopefully improve the video capture rate and OpenCV processing rate. However, I find a confusing mixture of outdated system images and build instructions for the BB xM. Compared to the excitement around the BBB, the BB xM feels somewhat like a ghost town. Now that I'm comfortable running Angstrom and systemd on BBB, I find that the Narcissus build server will apparently only successfully build images for an outdated Linux kernel without systemd. For those of you who are successfully using the BB xM with OpenCV and v4l2, what recipe are you following? I've been trying to follow somewhat older examples (such as this: http://blog.galemin.com/2011/04/li-5m03-camera-on-beagleboard-xm/) without much success. The images either don't build, don't boot or are really crippled compared with the BBB environment. I'd like to start with a known good image with support for things like v4l2, opencv, and wlan...doesn't need to run X11 even, just so long as I can ssh to the box and run our video capture and processing code. I'd also like to run the simplest linux possible since I have no need to do anything else on the video processing box. Can anyone point me to such a thing?

Re: [beagleboard] Re: Program C++ through putty using VI (Library installations needed?)
I was wondering if it is possible to write a c/c++ code in vi through SSH on Putty and then generate an output file and run directly on the beaglebone? Yes, if your program is simple (small), this is the easiest approach since you dont have to setup a cross development environment. I used the code by Derek Molley on his website: That uses FILE, fopen, fclose, sleep, NULL, etc. I'm getting errors about these. Am I supposed to install some kind of libraries or a arm-gnueabi compiler before I try to run programs that access the GPIOs and the LEDs ? make sure you use glibc stdio library. AFAIK, everything on the beagleboard is memory mapped; but if you ever need to io access, make sure you use ioperm to request io access permission, and outb or inb to write and read from io address. Do, if you compile on the board, you do not to install a cross compiler. Also is there a better OS than Angstrom for beginners on BBB? How is the Ti SDK? Angstrom distro comes with a package manager already, use opkg command to install and search for packages. I, however, have a custom distribution that i geared for embedded, industrial application, it is harder to develop on it because it does not come with a package manager.

[beagleboard] Re: Is it possible to run BBB off cheap rechargeable batteries?
I do a lot of BBB work with 1S, 2S, and 3S LiPo packs. Remember, the lower the voltage the higher the current requirements are going to be on the batteries. Pretty sure that I've run from a 2xAA alkaline pack but I know that the LiPos can easily supply the current. During boot I've seen spikes up to 1A at 3V - which is typically where you'll see the brown outs. I'm using a buck/boost regulator that allows for a large input voltage range (3-14V). -Ron On Saturday, November 9, 2013 8:09:56 PM UTC-6, rowland@gmail.com wrote: I have been trying to figure out a way to run the BBB off cheap rechargeable batteries, either 9V or 6 to 8 AAs.

If you connect 9v to an 7805 about 40% of the power is converted to heat. There are much better solutions available. BTW @Ron: What buck/boost regulators are you using.

I'm using jack to capture sound from a custom-made soundcard connected to the beaglebone. Until very recently jack was running just fine, however, suddenly I can't start the jack server anymore as it crashes with a 'Bus error'. Only a few hours ago I was able to start a jack server with: jackd -d alsa -p 256 -n 4 -C hw:0 -r 48000 -i 8 Then I just installed g++ and libjack-dev packages in order to compile a simple jack client.

[beagleboard] Source files for DCAN drivers?
Hello users of RobertCNelson's ubuntu/kernel. I've been having some problems which seem to relate the CAN bus. Details of the issue itself are fairly redundant with regards to my actual question, but are as follows: With CAN running and traffic present on the bus, when I do, for example, a very large data transfer from my host machine (over wifi with an ath9k_htc usb wifi device on the BBB in access point mode) using scp, the system regularly locks up (and is subsequently rebooted by the watchdog). Sometime it gives no stack trace messages, but when it does it appears as if various CAN related functions were being processed. Performing this test with the same setup, but can physically disconnected, presents no issues at all. So I thought I'd take a look at the can driver source files and reading the info from TI here ( http://processors.wiki.ti.com/index.php/AM335X_DCAN_Driver_Guide) was expecting to find d_can.c and d_can_platform.c in KERNEL/drivers/net/can/d_can/, but found that only the equivalent c_can files were present - so it seems the very latest can drivers are not being used. So I have two questions I'd greatly appreciate some help on: 1) Is it possible to integrate the d_can driver files into this kernel? 2) How would I go about starting to do this? Cheers, Andrew Glen. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Audio Cape with Beaglebone Black
I'm having difficulty with this setup. I have a BBBone Black running the stock OS image from Angstrom, attached to an LCD7 display, and the Sound Cape. I've modified my uEnv.txt file to match that which is listed below. However, whenever my part starts to boot, the display blinks twice and it then goes back like it is rebooting. Is there something else I need to do to make this work with the LCD cape that I am missing? On Sunday, October 27, 2013 11:21:32 AM UTC-5, Yasir K wrote: It worked!! Well, I guess I didn't even know what I was staring at for 3 days, just removed the EMMC disable part and it works! Here is my uEnv.txt file now: optargs=quiet drm.debug=7 capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-BONE-AUDI-01 Thanks so much Martin! However, I still have really poor quality audio playback from the cape using mplayer and an mp3 file. Where should I start to try and fix the audio quality issue? Also, it only works once very 2-3 tries. Any pointers to help me fix this issue would be much appreciated.

Try eliminating BB-BONE-EMMC-2G from the disable list in uEnv.

Re: [beagleboard] Re: Is it possible to run BBB off cheap rechargeable batteries?
Hi Ron, On Mon, Nov 11, 2013 at 2:32 PM, Ron B ron.batt...@gmail.com wrote: Dieter, you're right, linear regulators do waste a bunch of power. Just FYI, I took a *quick* look at the ADP and it doesn't look to me like it's going to have enough power for the BB. I'm using the TPS63061. It's a great part but the footprint isn't exactly prototype friendly. If you're interested, I have a small write-up and pic of my board here http://andicelabs.com/beaglebone-power-bar/. Very nice. Would it be possible (or perhaps permissible) to incorporate your design into my board? I'm planning on designing a cape which will do the following: 1 - Take an input voltage and use a step-down converter to produce 5V for the beaglebone 2 - Have a switch to toggle between wall power and battery power, and also a monitor to disconnect the battery if the battery voltage drops too low. 3 - Have the circuitry to talk on the bioloid bus (a single-ended half-duplex multi-drop megbit serial communication channel). 4 - Have an on-board I/O processor which sits on the bioloid bus. So I'm basically combining my brothers power board: http://www.huvrobotics.com/shop/index.php?_a=viewProdproductId=7 USB bus interface: http://www.huvrobotics.com/shop/index.php?_a=viewProdproductId=5 (except I'm going to go directly to one of the beaglebone UARTs) And a general I/O board: http://www.huvrobotics.com/shop/index.php?_a=viewProdproductId=6 except it will be all surface mount components. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
