Hi, can some one clarify below items.
1)Like to know TC399 supports gPTP ?
If only hardware support then can we use AVNU gptp stock on top of TC399.

2)From the link below 802.1AS is supported for TC377.

AURIX ™ TC377 Automotive Secure Gateway - Infineon Technologies

Does that mean hardware support only ?
Can we run AVNU gPTP stack with the devkit ?

Hi aravind403,

yes, gPTP is supported. The Ethernet MAC in TC399 is supporting timestamping in hardware. You can run gPTP, PTPv1, PTPv2, etc.. on it.

In case you want to implement AVB (because you are referencing to AVNU) I can give you quite more detailed information about implementation hints (I²S / TDM interface, media-clock recovery for audio-interface, time synchronization of audio-sample to PTP clock, etc..) Just ping me directly
