That's appropriate.  If you don't know what you're doing and choose
not to do the work to learn then you should expect failure.  By the
way even if you have a supported input pin you have to have an NTP
that supports PPS.

It would be an impossible task and it's working backwards.  If you
want an "embedded" system based NTP server then you should search for
a working product/design/implementation and then buy that.  Don't buy
something and then hope you can get it to work unless you're a
Time-Nut.

By the way, you build embedded systems and you build them to do what
you want.  You use development boards like the RPi and BeagleBone to
develop embedded systems.

People looking for inexpensive, low overhead NTP appliances should be
supporting Partially Stapled's Laureline development.
