DSA switch port is stop receiving ptp packets from the master after ptp4l is started #49

Open msmudide opened 8 months ago

msmudide commented 8 months ago

Hi All,

I have a zynq 7000 board with an 88E6393X switch running linux kernel 6.1.30. The ports 3, 9 and 10 are external ports and another port is connected to zynq mac. port 3 is connected to ptp master. The following tcpdump command shows the announce, sync and follow up from master.

tcpdump -i lan3 ether proto 0x88f7.

When I ran ptp4l on lan3, the lan3 port stops receiving the ptp packets from the master and the tcpdump shows only pdelay requests go from the lan3.

Any idea what might be the problem?

Don't understand why ptp4l is choosing /dev/ptp0 as ptp clock. The /dev/ptp0 is for the gem0 of the zynq. I thought, if I use -i lan3, then ptp4l uses the timestamping unit of the switch port 3.
