Figured it out
To enable the ADC in the global device tree file (am335x-boneblack.dts) I
needed to replace this:
713 tscadc@44e0d000 {
714 compatible = "ti,ti-tscadc";
715 reg = <0x44e0d000 0x1000>;
716 interrupt-parent = <0x1>;
717

The instructions found here:

likely do a fine job for doing so on the bone that is also attached to
an internet connected network (I wouldn't know as my bone presently is
*not* on such a network). That being the case, how
ok,
a bunch more looking has shown that it's the *pm-suspend* and*

power states do
they bring the beaglebone to and what rails end up remaining powered or
not?

Hello all,
I'm trying to get in the habit of enabling all the hardware that I need on
the beaglebone black via modifying the main device tree
file am335x-boneblack.dts which I derive with the dtc from the
am335x-boneblack.dtb file available under /boot/dtbs or /boot/uboot/dtbs in
a Debian insta

on the software side of this, where might I find the code that does this
now. for instance if I type shutdown at the prompt how does this actually
work? is the power sequencing all in the shutdown binary, or the kernel,
some of each, or where exactly? there is a shutdown command but what does
it
Mike,
The project sounds interesting.
I would recommend partnering with someone like Adafruit, Sparkfun, or
Makershed. There are about two million things which you need to get correct
to successfully being a new product to market. Logistics are a nightmare.

Hi,
Please correct me if I'm wrong, but this is my understanding with a 3.14.x
or newer kernel:
Since it looks like you want continuous sampling you might want to use the
hardware buffer in iio.
Normally you would use something like the generic_buffer.c [1] as a sample
application, but the eve
Hi,
I have installed Ubuntu Precise 12.04, and have discovered a weird problem with
the network interfaces.
What I have setup is a USB wifi adaptor connected to my Beaglebone Black, and
sometimes I connect it to Ethernet for debug. The wifi is not exactly used for
connecting to a network, but a

It depends on what you plan to do with the DDR state and if
you want to preserve it. I have never tired it, but it should be possible.
You need to look at the datasheet for the TPS65217C for the
power sequencing and power down modes available.

If you can, and make your IP config static, the interface should come up
faster. Also, although I am not sure what it is, I think there is a "fix"
to shorten how long it takes for DHCP configs to come up.

You are right! I studied the Debian documentation yesterday and modified my
/etc/network/interfaces file, and it did work! It isn't fast to come up,
taking about 90 seconds, and probably needs the 5V adapter connected, too.
I made exactly the changes you put here. Quotes should be around the nam
You probably measured this short? If so I would advise against such
practice, because resistance measurements might exceed (or reverse) the
maximum allowed voltage on many pins.
