Part Number: AM5728
My board is AM572x Rev 1.3B. When the board delivered to me, first I want to make the board output PPS signal with PTP operating. So I followed the next link.
After I set up u-boot environment variables and device tree file, and hardware modification, I modified the pps_enable file to PPS_ON(1). But it didn't work.
Also I operated ptp4l program with another TI EVM(EVMK2H). I connected two EVMs on each eth0 port with ethernet cable directly. It looked operating normally. But when I connected two EVMs and PTP supported network switch(RSG-2488), AM 572x didn't work. It looks like that it could not catch timestamp messages from other devices.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Schuyler Patton:
I only used one switch. I watched the packets by the wireshark program. I tried ping test by the AM572x board to grand master clock. I saw that the sending message was from the eth3 port in AM572x boards, but the destination port was not same, eth2.
