For usability I suggest making more of a distinction between the
different STM32 files. Users who have not done much embedded can
(and rightly so!) quickly get confused about the various file types.

I'm not so sure there - having native packages for firmware means
that the end-user only needs to install a *single* package with their
native package manager, to get everything they need.

If there already is some infrastructure (scripts..?) to create the
various packages then I would favor packaging the firmware the same
way too.

I do not like OpenOCD at all, and I even was a maintainer for a while.

Please see if https://github.com/stef/pyrsp might work instead.

I think include them in the base package. Fewer moving parts.
