My bad. I didn't think the M8F did Timemark as I missed it in the
M8F docs and didn't see EXTINT0 nor EXTINT1 pins in the pin list for
the M8F. Apparently it uses the FREQ_PHASE_IN as EXTINT for
Timemark. <br>
<br>
The first email you sent out had text that quoted "EXTINT0", which
makes me think EXTINT0 of an M8T and not the EXTINT of an M8F.<br>
<br>
I'm not getting anything out of the thesis pdf that suggests an M8F.
On page 35, it does mention using an u-blox NEO-M8T. <br>
<br>
The M8T can produce Timemarks upon interrupt, 0 + 1, through pins
EXTINT0 and EXTINT1, output as UBX-TIM-TM2 messages. If all we're
after for this is Timemarks, then the M8T is a lot less expensive
than an M8F.<br>
<br>
Have I missed something along the way and that we're not looking to
do what the thesis did and are on to something else?<br>

The part in question is a NEO-M8F, not a NEO-M8T
