testptp

Build

gcc testptp.c -o testptp

Here we use Intel I210 for example.

Set SDP0 channel 0 as PPS output with 1Hz

sudo ./testptp -d /dev/ptp0 -L0,2 -i 0
sudo ./testptp -d /dev/ptp0 -p 1000000000

Set SDP1 channel 1 as PPS input

sudo ./testptp -d /dev/ptp0 -L1,1 -i 1

Listen PPS input event for channel 1

sudo ./testptp -d /dev/ptp0 -e 100 -i 1

Detect only the rising edge

EXTTS_RISING=1 sudo -E ./testptp -d /dev/ptp0 -e 100 -i 1

Detect only the falling edge

EXTTS_FALLING=1 sudo -E ./testptp -d /dev/ptp0 -e 100 -i 1
