Hey Rob, thanks for asking -- this function is definitely under-documented. The short answer is: This function should be called for synchronous operations, but only on X3x0 will it make any difference if you don't call it.
What does it do? This function provides additional synchronization on top of the timekeeper synchronization. Currently, only X310 needs this for the DAC synchronization. So why is not called in multi_usrp_rfnoc? To be honest, I had to double-check the code myself On Wed, Nov 17, 2021 at 12:04 AM Rob Kossler <rkoss...@nd.edu> wrote: > Hi, > I recently stumbled across this synchonize_devices() function and I'm > wondering if I need to be calling it.
