In the “in” table. the pin numbers are referred from the DPLL Priority See Section 4.2, “DPLL Priority”.
In the “out” table pin 0 is SMA1 pin 1 is SMA2, all the other values do not modify.
Changing the DPLL priority list:
# echo "prio <prio_value> dpll <dpll_index> pin <pin_index>" > \ /sys/class/net/$ETH/
device/pin_cfg
where:
Note: A prio value 15 disables the input for synchronization.
Example:
Set priority 1 for pin 3 on DPLL 0:
# export ETH=enp1s0f0
# echo "prio 1 dpll 0 pin 3" > /sys/class/net/$ETH/device/pin_cfg
Changing input/output pin configuration:
# echo "<direction> pin <pin_index> <config>" > /sys/class/net/$ETH/device/pin_cfg
where:
Note: The eSync setting has meaning only with the 10 MHz frequency, you need to have eSync
to have the same setting in both ends of the SMA.
prio_value = Desired priority of configured pin [0-14]
dpll_index = Index of DPLL being configured [0:EEC (DPLL0), 1:PPS (DPLL1)]
pin_index = Index of pin being configured [0-9]
direction = pin direction being configured [“in”: input pin, “out”: output pin]
pin index = index of pin being configured [for in 0-6 (see DPLL priority section); for out 0:
SMA1 1: SMA2]
config = list of configuration parameters and values:
[ "freq <freq_value_in_Hz>",
"phase_delay <phase_delay_value_in_ns>" // NOT used for out,
"eSync <0:disabled, 1:enabled>"
"enable <0:disabled, 1:enabled>" ]
