Regarding PTP Implementation with T1022.

anilks — Fri, 12 Apr 2024 09:28:42 GMT

Hello All,

We have a requirement to implement PTP on a T1022 based custom board(Operating system: linux-4.1.8-rt8).
The board has a PHY with time-stamping capabilty. When I check the timestamping capabilities of the SerDes connected to this PHY with "ethtool -T fm1-gb1" it reports its capabilities as below:

ethtool -T fm1-gb1
Time stamping parameters for fm1-gb1:
Capabilities:
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

Please guide how to proceed with this implementation.

Your help with this is greatly appreciated.

Please configure Linux Kernel with the following option enabled.

CONFIG_PTP_1588_CLOCK_DPAA=y

CONFIG_FSL_SDK_DPAA_ETH=y

Please check your dts file with the following file included.
