Linux PTP IEEE 1588

Hii Everyone..,

I designed Ethernet board with Cyclone V(5CSEBA5U19A7N) using ethernet chip(KSZ9031RNX) PHY supported.

now i want to configure Linux PTP IEEE 1588 in my design. I am using Linux 3.10.31-ltsi angstrom version.

I followed some steps,but i am getting some errors in my serial console.

1)First I downloaded Linux source code from http://sourceforge.net/projects/linuxptp/files/latest/download.

2)I changed my design IP address similar to switch(CM-1600) IP address

3)I run make clean,make and make install command.

4)I set hwstamp by using the command hwstamp_ctl -i eth0 -r 1 -t 1.

5)Finally i run ptp4l -i eth0 -m -s command.

After that command my board receives master clock, but it shows some errors

/*************************************************************************************************

ptp4l[311.172]: timed out while polling for tx timestamp

ptp4l[311.173]: increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug

ptp4l[311.174]: port 1: send delay request failed

ptp4l[311.174]: port 1: UNCALIBRATED to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED

***************************************************************************************************/

I increased that tx_timestamp_timeout.still i m getting this error only.

If anyone knows information and documents or anything related to my query.please help me.I hope someone will helps me to debug this issue.

Thanks & Regards,

Chethan
