I measured the current (DC jack powered) my BBB (rev C, kernel v3.16.3)
draws at idle: ~200mA. Then I issued a *poweroff* (or *shutdown now*)
command, and after the system had halted I measured current draw at ~240mA.
This is a bare BBB with nothing attached (besides the serial debug cable).
It seems as though PWM does not work in v3.16 as in earlier kernels. Am I
overlooking something or does PWM not work yet in the more recent kernel
versions?
Thanks.

Thanks for the help - I figured it out... it was operator error. The
evaluation board that I was using with the Marvell chip apparently just
needed another connector plugged in for power. Once I plugged that in, the
interface was available for me to bring up.

The method I have found about adding optargs=text to the uEnv file doesnt
quite work. I am in console then but I cant see the login screen, there are
just some loading text strings. In the same time I can ssh to the

The beaglebone has to identify itself as a 'mass storage device' I believe
the original beaglebone whites did.
But I forget the procedure.

Would flashing the console only version of Debian to the beaglebone work?
It has no x-server code loaded and is a very small footprint.
You can use apt-get install to add things as necessary.

Ok, I figured this all out. There is no filling up of the disk from the

Actually, starting from the LXDE image and then removing stuff you do not
want works fine. *IF*, and this is a big if, you know exactly what packages
to remove for each thing you do not want. However, there is always aptitude

Your choice, either use the flasher which runs a flashing script of

That is the description of what a flasher image does,

a header). I then tested them all to make sure they worked for digital IO.

If logging was the problem, then you are correct. Logging was only one of
the possible reasons I was looking into.
