I am trying to do a rtsp from beaglebone black running angstrom to my linux
system. For that I installed gstreamer-0.10 and rtsp server on BBB. I sent
test patterns i.e. videotestsrc from BBB and I could see the colorful
bars on my host system. But when I attached the camera and started sending
Hi Jason, Hi all,
thanks for your hints. So I just used apt-get install
linux-image-3.14.25-ti-r37
like you preferred and it works like a charm ... After one reboot the can0
interface was there! :)

dtb-builder. For more
Hi, yesterday i received my BeagleBone Black and started to examine it,
written some programs in C to test it, but after some time i realized that
many projects in net is in bonescript or you need many other additional
parts to make projects. So i would like to start to learn how to program on
Quite old post but.I have same issue for my old Beaglebone WHITE
running 3.2.33 kernel
Is there any simpler method to avoid external ADC and split by software the
unused AIN pins to make them readable ??
Thank you very much

Hi,
I used /opt/scripts/tools/update_kernel.sh --ti-kernel) to move from
a 3.8.13-bone kernel to
the latest 3.14 TI kernel. This worked fine, however when I subsequently do
update_kernel.sh
(after rebooting) it once again downloads and re-installs the same TI
kernel. Any idea what is
happening
I think you are going to have to use an external ADC.
The good news is that you can get better accuracy and a lot higher
resolution by doing so. At the expense, of course, of some additional
cost and complexity. I ended up using an ADS1115 from TI that delivers
16bits of resolution at 800

Hi Steve
You need to install device tree compiler. I suggest you compile it from
source yourself, as there is a patch you need to apply. Here's my
instructions from a manual I wrote a while ago:
BBB git clone git://git.kernel.org/pub/scm/utils/dtc/dtc.git
BBB cd dtc
BBB git reset --hard
Guys I still can't get UART0 to work. Other ports are fine. Anyone has any
idea how to make UART0 available on BBB? I really appreciate any help!

Well it's quite sad that the book will be released only on December 31~
2014. The other tutorials are quite interesting and helpful, but he uses a
lot of other stuff like capes. I don't have such resources, so it would be
impossible to test what i learned and coded :(.

If you aren't doing anything with hardware (using capes, etc.) then doing
C/C++ on the BBB is no different from any other Linux system. There are
lots of resources for that kind of stuff. Even if you want to talk to
external devices using serial communications (UART) or some other standard
Does the USB work on your BBB? I thought UART0 was used for the USB. Both
of my Rev C BBB's powered up with USB working.

I found what I was looking for.
TI has a support package for the PRU C library.
The package contains headers and example code for PRU side operations.
You can get it using:

Thanks that got me a lot further along.
The problem I have now is the serial ports I believe I enabled didn't
appear in the /dev directory.
What I did was uncomment the lines like the following in
am335x-boneblack.dts, recompiled and installed:
#include am335x-bone-ttyO1.dtsi

Ok, so this just happened to me. What I think ultimately caused it in my

Do be aware with OpenJFX that JavaFX programs on the BBB will only run in
X11 with DirectFB being specified as the renderer. DirectFB on the BBB with
the current revision of OpenJFX that I was using had the bizarre GTK
requirement, which prevents the framebuffer (no X11) from being used. Also

a note on Revision A6: Noise issues were observed in other designs where
the clock oscillator was getting hit due to a suspected issue in ground

I don't think that's true! What I see on the manual is that UART0 pins are
not muxed with USB. I do need the USB ports although they're not in use
right now (but I try them occasionally and they're working fine). I also
couldn't find any dtb or dts files with ttyO0 in it's name to modify. So I
Which kernel are you using? I'm on 3.14.23-ti-r32 and all serial ports are
available under /dev/ right after a fresh flash. But I still needed to
rebuild DTBs to get them working.
