Hello sir,
Even we are using the DP83640. We able to time stamp the EVENTs but not the packet time stamping. I am not using PSFs. I am trying to read the PTP status register after sending an PTP version 2 sync message. But not TX_TS(Transmit timestamp ) bit is setting. Could you please tell me the sequence that you are following to configure the registers for packet time stamping. If you have an "wireshark" snap shot of your sent sync or delay_req message, please provide that one also.
Thankyou,
Sushma
