Hi, We have a setup of a master PC(Linux OS) and slave embedded HW running Linux OS connected via media gateway(not time aware) and synchronizing using IEEE 1588. With no application running on the HW, or dedicating a specific core to ptp, we are able to synchronize the clocks between the two systems. But when we have our application that uses ethernet bandwidth both on the receive and transmit side running on all cores, we see very frequent timeouts. We found that the timeout is happening when the slave responds to master and waits for the follow-up message from master within 1ms or 10ms (depending on the tx_timestamp_timeout parameter), the timeout occurs on the socket. Can you please recommend any way of prioritizing ptp packets over other traffic?
Thanks, Mani
