Can't use ptp4l on LS1043ARDB

Hi experts:

I am trying to use ptp4l on LS1043. I use the command in the OpenIL User Guide, but what i got is:

[root@OpenIL:~]# ptp4l -i eth0 -m -p /dev/ptp0 -f /etc/ptp4l_default.cfg
ptp4l[90.468]: interface 'eth0' does not support requested timestamping mode
failed to create a clock

 

And even with "-S", just for software timestamp, the output stays the same.  And the ethtool shows:

[root@OpenIL:~]# ethtool -T eth0
Time stamping parameters for eth0:
Capabilities:

          software-receive (SOF_TIMESTAMPING_RX_SOFTWARE)
          software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none

 

The user guide shows Linux PTP stack supports 1043, so why can't i use LinuxPTP?

Could you please help me?

 

Regards,

Jason
