reComputer J401 Carrier Board IEEE1588 PTP support


I read that the Jetson Orin NX/Nano module supports PTP, but does the J401 carrier board support it?

I’ve flashed my J401 Carrier board + Jetson Orin Nano 8GB with Jetpack 5.1.1

However, when I try to check the PTP capabilities; it does not seem to be present:

$ sudo ethtool -T eth0
Time stamping parameters for eth0:
	software-transmit     (SOF_TIMESTAMPING_TX_SOFTWARE)
	software-receive      (SOF_TIMESTAMPING_RX_SOFTWARE)
	software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none

I’m wondering if this is expected?
