Hi, I am using TI DP83640 PHY with Xilinx Zedboard (with Ubuntu 16.04 running on it)
I have followed the steps mentioned in the following mail thread to configure the Xilinx_emacps drivers to detect HW timestamps from PHY: https://linuxptp-users.narkive.com/i5cijFRH/linuxptp-on-zynq-with-dp83640 However on running the following command "ptp4l -P -i eth0 -f ./gPTP.cfg -m", I get the following error: ptp4l[265621.845]: selected /dev/ptp0 as PTP clock ptp4l[265621.900]: port 1: INITIALIZING to LISTENING on INITIALIZE ptp4l[265621.900]: port 0: INITIALIZING to LISTENING on INITIALIZE ptp4l[265623.000]: timed out while polling for tx timestamp ptp4l[265623.001]: increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug ptp4l[265623.001]: port 1: send peer delay request failed ptp4l[265623.001]: port 1: LISTENING to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED) ptp4l[265639.120]: port 1: FAULTY to LISTENING on FAULT_CLEARED I tried increasing the "tx_timestamp_timeout" to 10ms, 100ms. But it is not resolving the error Am I missing any step? Regards, Anmol
