There isn't much action here on Fridays or Weekends normally. Have you
gotten around to writing up your blog post describing the various
steps you have tried? It's a little hard to help you to debug without
understanding the full scope of what you have been trying to do.

The one other thing I will say, to repeat myself, is that I'd like you
to clean-up your code on github so that you have clean commit history
without any merge commits.

As I understood things, you had a linked executable but an empty section. Just
curious if your devices were showing up at all.

I wasn't expecting a generic macro.

The following is a simplified view of the 'linker set' mechanism.
The idea is similar to C++ static constructors and destructors without
compiler and linker support

Can you add more debugging info?
I glanced at your code, some comments, make sure you follow the
recommendations in libbsd.txt about modifying code taken from freebsd.
You also might find it more convenient to work on a branch instead of
a master, and to avoid merge commits.

your device must get added. I would also set break points to the probe
and attach functions of your device.

I do not know if anyone using the Pi with RTEMS currently has a debugger
working. Last year Alan posted in his blog [1] a configuration using a
