How to enable HW timestamping in PTP

I was able to compile Linux with PTP for the EZ-kit SC589.


Although the datasheet describes that hardware timestamping in the MAC is supported, I was not able to configure the linuxPTP (ptp4l) to use hardware timestamping, on none of the two EMAC's.


Also the timestamping in the Phy doesn't work.


The result of the <ptp4l -m -f ptp4cfg.cfg > command is :

interface 'eth0' does not support requested timestamping mode


The same goes for eth1 when changed in the config file.


The linux compilation is the one as can be downloaded in the cces-linux-add-in version 1.2.0.


Enclosed the config file
