Hi there,
I did a quick test of our board. Results were not bad, but not great either.
The design uses the RTC of the CC26X2R to keep track of seconds. We use Seconds_set() and Seconds_get().
Yesterday, I set the time at 11:38:00 as 11:38:00 and I asked it the time at it was 11:38:00 
Today, I asked it the time at 11:38:00 and it was 11:38:10, so there is a drift of 10 seconds during a 24 hours period.
This seems a lot for something being driven by a crystal.
Is there a way to adjust this? Maybe a driverlib call to SET something in the crystal pins?
I already know the way to GET the crystal frequence in a IO pin, by reading this document, section 6.3.

We are hoping we can adjust this for every board.
Please, let me know and have a nice day.
