I had the same problem (missing cape-manager ) in the newer kernel versions
a few weeks ago.
Needed to switch back to kernel 3.8.13 to get the cape-manager working. I
haven't had time to investigate more.
If you want to give it a try:
sudo apt-get update
sudo apt-get install linux-image-3.8.13-bo
Hi der.depp (lustiger Name),
is /sys/devices/bone_capemgr.9/ present in your file system?

In the datasheet I see that the BH1750 has a 1.8V logic. So you could try a
level shifter to adapt the i2c voltage to 3.3v.
Do you have a other i2c device or an oszi to check your i2c bus?

Hi,
I got a Macbook Pro (2000€) and it worked out of the box. So the problem
shouldn't bee related to OSX or BBB.
ssh works fine assumed you know the ip address of your BBB.
For file transfer google for OSXFUSE and SSHFS.

What device are you using? Is it 3.3V kompatible?
Check the following:
-Do you use the right pins? Pin 1 is located near the 5V jack and not on
the USB side. (see my photo for i2c-1)
-Don't mess up with SCL and SDA
-Is your device 3.3V compatible? If not you need a level shifter.
-Put two pull up
Pin 17 and 18 belong to /dev/i2c-0 in my opinion.
So try to change your code to
fd = open("/dev/i2c-0", O_RDWR);
or use pin 19 and 20.
To find your device use the i2cdetect command.
For i2c-0 use:
sudo i2cdetect -r 0
and for i2c-1 use
sudo i2cdetect -r 1

Hi,
I tried the libpruio solution with kernel 3.14.xx but there is no

This libpruio looks good. The problem is that I can't get it running.
I think this is related tu the kernel (3.14.x or 3.17.x) version I am
using. There is no capemgr any more.
Could you suggest me a linux image or kernel version I should use?

Hi,
I am using kernel 3.17.1-armv7-x3 on my BBB and I want to read the analog
inputs available.

Hi,
you need to ground your servo to both grounds. To the BBC ground and your
power supply. You need a common ground to make everything work.

Hi Allain,
what happens when you start your application without the -qws option?
In my opinions you only need this option when you are using a framebuffer
device on the command line. But in your video you are already running an
x-server.

You need a Motor Driver like this one
https://www.sparkfun.com/products/9457
to do so.
If you are able to generate a PWM signal with Python it should be no
problem.

Thank you for this great post. I am also interested in using Matlab/Simulinkor
Scilab/Sicos on BBB.
Perhaps you could give me some additional information.
-What tool boxes do I need beside Matlab/Simulink? Some code generation
tools?
-Are there some simulink blocks for GPIO, PWM, analog input, I2
Does a compiled program run on the target?
With some compilers I had problems with dynamic libraries on the BBB. I
suppose this was related to hard/soft floating point.

Perhaps you could try to install Cygwin with an ARM cross compiler.
Or try ARM DS

Or search the TI website for a cross compiler

You may use the same cross compiler as in your eclipse installation.
You just need to specify the path to this compiler in QtCreator and in the
configuration file you use to build the qt-libs.
In my case the path is
/usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++

Hi,
I got the same problem. When I plug in a 5V power supply one LED ligths up
and goes off again. After that nothing happens.
When I plug in the USB cable (in addition to the 5V) the BBB starts booting.
Is this behavior normal?

What is the part number of the power supply?
unknown.

Consider the configuration. You need to do it for Release and Debug

You can use a PWM output to drive your servo. Set the PWM cycle frequency
to 50hz and the duty cycle to 1.5 ms (~7% = center position). Varying the
duty cycle +/- 0.5ms should drive your servo to left and right.
Power the servo by an external power source not the GPIOs of the board.

The solution from Fernando Rocha worked for me.
It seems that on the target is no support for the hardware floating point
unit because of missing runtime libraries.
