[Linuxptp-users] PTP implementation on AM335x

[Hardik G. <har...@gm...>]

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 ?
