Hi,
I was using Linux ptpd-2.1.0 as master, Naional Semiconductor ethernet chip DP83640 as Slave, I would be able to have hardware timestamped of Synchronization message on Slave side(I run "./ptpd2 -c" on master side), but if I run "./ptpd2 -GW" with version ptpd-2.2.2), I won't be able to get hardware stamp on slave side(run the same source code).
So anybody knows the differences between v2.1 and v2.2 on hardware timestamp related, or it could be configuration related?
Thanks for your help.
