Hi,
A conceptual question: for the b205 mini, how does the FPGA get the
64-bit VITA timefield? I know the PPS/10 MHz can be used to sync the
clocks to, but trying to understand how the timestamp is synchronized
to a UTC/known-good reference value. Reading the HDL, it seems that
the timestamp is programmed from software, but needed confirmation.
Thanks
Chintan
The software side of things takes care of that. If the on-board GPSDO
is working, it will get a GPS-based timestamp from that.
Otherwise, the application can set the time to whatever it wants see API
elements:
set_time_now()
set_time_next_pps()
set_time_unknown_pps()
