Using PTPv2 with Digiface Dante

Hi guys,

At my company we have bought a Digiface Dante. We want to create a local network. In this network there is a Rapberry Pi 4 with GPS module, acting as a Grandmaster clock.

We switched on the AES67 on Digiface and connected everything to one switch. Raspberry can ping Digiface and tcpdump shows that PTPv2 packets are transfered. But in the Dante Controller we see that Digiface is still playing the role of the Master Clock. Why is that? How can we make it follow the Raspberry master clock?

Raspberry is using ptp4l, and domain is set to be 127.

Any help is appreciated
