Hello=20 all

I'm = trying to=20 understand if we need to move from MPC8347 to MPC8360 in our=20 boards.

One of = the features=20 that most attracts, is the eTSEC which includes support for IEEE 1588 = PTP time=20 synchronization.

I need = to=20 synchronize the clock of 3 boards via ethernet, I need a time = resolution of=20 under 1ms.

Has = anyone had the=20 pleasure of playing around with time synchronization = ?

Do I = really need the=20 hardware capabilities for this type of time resolution ? or can I = implement it=20 in software ?

Thanks = in=20 advance.
