Issues of the Jetson series selection

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

and ethtool -T eth0 returns

Time stamping parameters for eth0:
	hardware-transmit     (SOF_TIMESTAMPING_TX_HARDWARE)
	software-transmit     (SOF_TIMESTAMPING_TX_SOFTWARE)
	hardware-receive      (SOF_TIMESTAMPING_RX_HARDWARE)
	software-receive      (SOF_TIMESTAMPING_RX_SOFTWARE)
	software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
	hardware-raw-clock    (SOF_TIMESTAMPING_RAW_HARDWARE)
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes:
	off                   (HWTSTAMP_TX_OFF)
	on                    (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
	none                  (HWTSTAMP_FILTER_NONE)
	ptpv1-l4-sync         (HWTSTAMP_FILTER_PTP_V1_L4_SYNC)
	ptpv1-l4-delay-req    (HWTSTAMP_FILTER_PTP_V1_L4_DELAY_REQ)
	ptpv2-l4-sync         (HWTSTAMP_FILTER_PTP_V2_L4_SYNC)
	ptpv2-l4-delay-req    (HWTSTAMP_FILTER_PTP_V2_L4_DELAY_REQ)
	ptpv2-l2-sync         (HWTSTAMP_FILTER_PTP_V2_L2_SYNC)
	ptpv2-l2-delay-req    (HWTSTAMP_FILTER_PTP_V2_L2_DELAY_REQ)

According to the linuxptp website the requirements for using ptp are met by Xavier AGX.

Thank you for your help!
