gpsd is tested, and used, on ARM, ARM64 and CentOS.  Should work fine.

Petalinux.  That's a new one.  Maybe someone else here has tried that?

Since scons is pure Python, it should work anywhere.

We recommend NTPsec.  NTP Classic not getting many updates in the last
few years.

I'd guess you need to edit nothing in gpsd.  Many people cross-compile
gpsd with simple scripts.

Here is how one person did it:

https://stackoverflow.com/questions/50923719/how-to-cross-compile-gpsd-which-comes-with-scons-using-only-command-line-options

I also know there is a Yocto package for gpsd.  It cross compiles gpsd
for just about every embedded target there is, using only scons
arguments.

Maybe someone here is more familiar with the cross-compile, petalinux or
yocto world than I am.
