I've been connecting a Parallax NEO-7M to a beaglebone green..
GPS messages through the UART are easy.
pps less so.. I'm sure it's a matter of correctly configuring and
thrashing through the GPIO assignments with the capemgr - which
interestingly has had two substantial versions - most of the online
tutorials and material refer to the older one.
