In case anyone is searching this in the future for the E320, I managed to get 
time sync working in the background by cross compiling NTP and configuring 
ntp.conf to use the loopback address for the GPSDO:

```
# GPS Serial data reference
server 127.127.28.0 minpoll 4 maxpoll 4
fudge 127.127.28.0 time1 0.0 refid GPS

# GPS PPS reference
server 127.127.28.1 minpoll 4 maxpoll 4 prefer
fudge 127.127.28.1 refid PPS

```
