Dear all,
I have 2 intel i210 NICs and I want to enable one as a PPS source and the other
as a PPS sink.
I get the PTP_EXTTS_REQUEST2 failed: Operation not supported error when running
ts2phc.
Am I doing something wrong? Should I be using some special driver to make this
work?
Some outputs are:
1. ethtool -i enp1s0
driver: igb
version: 5.15.0-43-generic
firmware-version: 3.25, 0x800006eb, 1.1824.0
2. uname -r
5.15.0-43-generic
3. sudo phc_ctl enp1s0
phc_ctl[17465.576]:
capabilities:
62499999 maximum frequency adjustment (ppb)
0 programable alarms
2 external time stamp channels
2 programmable periodic signals
4 configurable input/output pins

doesn't have cross timestamping support
doesn't have adjust phase support
4. sudo ts2phc -c /dev/ptp0 -s generic -m
ts2phc[17625.163]: PTP_EXTTS_REQUEST2 failed: Operation not supported
failed to arm PPS sinks
5. sudo ./testptp -d /dev/ptp0 -z
