Hello, I am working on AM335x running on linux -3.2.0
I want to implement PTP and I have done the following configuration 1. Select PPS Support - Device Drivers ---> PPS Support ---> <*> PPS Support 2. Select PTP Clock Support - Device Drivers ---> PTP Clock Support ---> <*> PTP Clock Support 3. Select TI CPTS PTP Clock - Device Drivers ---> PTP Clock Support ---> <*> TI CPTS as PTP clock As per my study AM335x supports Hardware time stamping at MAC layer. In order to confirm this I am using ethtool. root@phyCORE-AM335x:~ ./ethtool -T eth0 Time stamping parameters for eth0: Cannot get device time stamping settings: Operation not supported starting from which kernel version support is there ? how to confirm HW time stamping feature ? Regards, Hardik A Gohil
