Several Possibilities:
1.) When you write something to the file system, either a new file or
modify a file, you need to
type 'sync' on the command line to flush the buffers to the file system,
otherwise you can
loose the changes at unmount/shutdown.
2.) On the earlier Debian distributions, like

You are looking on BUS 0 and BUS 1 for the sensor.
You may need to change the PIN-MUX so that I2C2 is actually connected to

Well, Bluetooth being recognized by the kernel and Bluetooth being
accessible via the API are two very different animals. Enabling the
Bluetooth stack in the kernel, as well as the device drivers, is the first
step. Once that portion is done, your Bluetooth device must be registered
within
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 there!
I am developing a software that is to run on a BBB, runing Debian wheezy

If you get bluedroid working and it is a viable approach, let me know and

how well audio support is working via HDMI or audio cape. Bluetooth is a
more pedantry as i write up things you can do in u-boot on the BBB

Try configuring the kernel using the menuconfig target (like make
menuconfig in the makefile). I suspect that you are manually setting
something in the .config and there are other settings that conflict with
it. Normally, these conflicts are managed via the Kconfig or menuconfig
interface
This is a good question. I hope someone answers for you Gabe.

I just saw that your tx buffer is different from your expected string
char tx_buf[9] = {0xC5,0xC3,0x01,0x00,0x00,0x00,0x00,0x00,0x76};
string C5C3010076
0x00 doesn't mean two times 0. If you want to see 18 characters so you need
to send 18 characters.
