I would like to buy a Jetson for controling my system. Respect to the synchronization, I would like to use the PTP 1588 to synchronize my system. Besides, I want to use the Jetson product as my time master to synchronize my hardware.
The question is: can you tell me which model can support hardware timestamping in Jetson series?
I checked that Jetson Nano could not support hardware timestamping, but I did not know other board, Jetson Xavier NX, Jetson AGX Xavier and Jetson TX2, which model can support both hardware timestamping and software timestamping?
I will appreciate if you can give me some ideas/results!
I am moving this from the Community Information forum to the Jetson Nano forum for better visibility.
Thx for your help!
Don’t know if it helps as I don’t have any experience with it: on my Xavier AGX with JetPack 4.5.1 a “
apt search 1588” returns
linuxptp/bionic 1.8-1 arm64 Precision Time Protocol (PTP, IEEE1588) implementation for Linux ptpd/bionic 2.3.1-debian1-3 arm64 Precision Time Protocol daemon
ethtool -T eth0 returns

According to the linuxptp website the requirements for using
ptp are met by Xavier AGX.
Thank you for your help!
