PTP TEST( ethtool -T information)

[Juan Jonathan]

I am trying PTP and PPS function with LINUXPTP from sourceforge and testptp from kernel 4.1 document. We use "ethtool -T" to get the following. Is the "PTP Hardware Clock:0" is the correct value.

===============================================

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)

        ptpv2-event           (HWTSTAMP_FILTER_PTP_V2_EVENT)

======================================================

We use testptp to get the clock capabilities. it show the following message.

We want to design a pulse output function. Can  the hardware config do this function?

=======================================================

beaglebone:~/TESTPTP# ./a.out -c

capabilities:

  1000000 maximum frequency adjustment (ppb)

  0 programmable alarms

  0 external time stamp channels

  0 programmable periodic signals

  0 pulse per second

==================================================

Thanks for your help

Hi Juan,

Did you get reply to this question ?

How to check if my NIC/PHY supports PPS outout ?

Thanks,
