Remember "bare metal" here...no lumbering pig kernels like Linux or even NetBSD

Right. And at 92K of RAM and 256K program memory, many PDP-11 operating
systems would fit reasonably well and run a hell of a lot faster
(assuming the feasibility of a port, which is next to nil).

It's
ironic that it seems increasingly hard to do anything "bare
metal" without a graphical UI IDE on a desktop and a USB stack on the
"bare metal".
That is true if you start out with a SOC that never was intended for
embedded systems use, like this part was.
All of the I/O is just... wrong.
If you want to be doing bare metal development, you should be using
something like this

It's small, it's 'slow' but the I/O on it is actually USEFUL for
building stuff.
