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
Time stamping parameters for eth0: Capabilities: 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!
