I've written some application notes (available at
https://github.com/pmunts/muntsos/tree/master/doc) that I always thought should
become chapters in a book about embedded systems development using Linux. Two
of them are directly applicable to the BeagleBone and kin and most of the
others are i
Sure, go ahead and use it.

config-pin.c isn't part of the kernel; it is just a C reimplementation of the
userland config-pin script. It isn't a perfect replacement. It eliminates the
platform configuration tables in the script, but it has some limitations. One
that comes to mind is that config-pin -q will display "defa
You could try my config-pin replacement written in C:

Unlike the original config-pin script, my replacement derives all pin
configuration information by reading files in /sys, and doesn't have any
platform dependencies. I haven't
I have finally gotten around to building a native GNU Modula-2 compiler package
for Debian Stretch on the BeagleBone. It took about 9 hours to build on a
SanCloud BeagleBone Enhanced with 1 GB of RAM. I wasn’t able to build
successfully on a regular BeagleBone with only 512 MB of RAM.

It is a race condition. The GPIO pin files don't exist until the pin is
exported by writing the pin number to /sys/class/gpio/export. The pin files
are created neither instantaneously nor synchronously.
Your code or library is trying to open one of the pin files after exporting but
before the
I couldn't find anything like this so I had to develop it myself:

It works great in a BeagleBone Click Shield or a mikroBUS Cape, too.

Here is a seriously off the wall but fun project: How to develop .Net Core
applications to run on a PocketBeagle. I think the PocketBeagle is the
smallest system that can run .Net Core (at least among boards that are commonly
available).
