Hi friends,
I have a BB white and one BB audio cape rev B1. kernel version 3.8.13 and
debian rootfs.
I'm able to use the BB audio cape with this setup for audio output nicely
but as the audio input is line in, I can't use the mic in directly.
So, using the mic input, my hardware person has made

So I took the sources from your git repository and I'm trying to force the

Do you know if there is an easiest way to do it ?
I'm sorry, I'm a beginner concerning kernel

I can arrange to have one of the 4D Systems 4 LCD's sent to you. If
that would help. I could also do the kernel testing here to help
isolate the offender. I should be able to apply the patches one at a
time and do a quick partial recompile after each patch is applied?
To answer your question
What kind of solutions are others out there using to protect GPIO pins
during boot? I have a sensor connected that is loop powered so it will be
applying voltage at all times to the BBB. My thought is to use some sort
of FET bus to protect the board. Ideas or thoughts?
Thanks.

Power the sensor from the 3.3V rail or use the reset pin as described on
the Wiki.

Hello all;
I seem to be having a problem writing to ttyO1.
Here is the really simple code and the result on the console:
Code:

var sp = new serialPort(/dev/ttyO1, { baudrate: 9600 });

Basically, after some Google-ing I realized that I have to wait for the
serial port to be open before reading from or writing to it.
This is because it communicates asynchronously.

It turns out that a colleague has an Element-14 4.3 LCD cape here at work.
I just booted up after changing uEnv.txt. Hard to work on the BBB at that

Hi,
Background: I have a BBB that I am setting up to run with machinekit to
drive a mill.
I have been testing with an early machine kit image, and then I updated to
the most recent image.
Upon updating I started to have problems where the cape manager stopped

Hi Brandon,
I'm currently using mmap (in Python) to achieve register wide GPIO. I'm
concerned though, that the kernel still thinks it owns that memory and
might inadvertently write to it (for ex: if you forget to disable the
heartbeat trigger). Do you know of a way to disable the sysfs
I believe the only way is to remove them from the main device tree overlay
since that will be loaded before anything else you can do. Decompile the
dtbo, remove the usr led entries in the resulting dts, and recompile to
dtbo (at least this is how it used to work).

You have to enable the ocp master port (section 10.1.2) to access main
memory. Here's an explanation
