Syncing Xavier with external device

Hello, I have Xavier board with Drive software 9.0 on it. I am trying to sync one Xavier with other device, where is Xaviare slave ande other device master, and I keep getting this log

And the time remains unsynced.

Hi Tegdif,

Please refer to the time sychronization use cases described in “Ethernet 100M/1G Networking” section of “NVIDIA DRIVE OS SDK Development Guide” below. Thanks!

https://docs.nvidia.com/drive/drive_os_5.1.6.1L/nvvib_docs/index.html#page/DRIVE_OS_Linux_SDK_Development_Guide/Network%20Setup/network_ethernet_100m_1g.html#wwpID0EPHA

Hi Tegdif,

Please confirm this answers your question so we can close the topic.

Thanks!

This was the page i was following the whole time. I found workaround: when i first start external device with master and then Xavier, syncing is happening.

Thank you for sharing back!
