Yo Jacob!
Just to summarize what I just tried, that failed. I repeated several times,
similar results, it just took varying times before going crazy, usually
10 to 90 seconds.
Here is my hardware:
kong ~ # ethtool -T eth0
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)
all (HWTSTAMP_FILTER_ALL)
ptpv1-l4-sync (HWTSTAMP_FILTER_PTP_V1_L4_SYNC)
ptpv1-l4-delay-req (HWTSTAMP_FILTER_PTP_V1_L4_DELAY_REQ)
ptpv2-l4-sync (HWTSTAMP_FILTER_PTP_V2_L4_SYNC)
ptpv2-l4-delay-req (HWTSTAMP_FILTER_PTP_V2_L4_DELAY_REQ)
ptpv2-l2-sync (HWTSTAMP_FILTER_PTP_V2_L2_SYNC)
ptpv2-l2-delay-req (HWTSTAMP_FILTER_PTP_V2_L2_DELAY_REQ)
ptpv2-event (HWTSTAMP_FILTER_PTP_V2_EVENT)
ptpv2-sync (HWTSTAMP_FILTER_PTP_V2_SYNC)
ptpv2-delay-req (HWTSTAMP_FILTER_PTP_V2_DELAY_REQ)
Here I make sure no conflicting daemons:
kong ~ # killall ptp4l phc2sys
ptp4l: no process found
phc2sys: no process found
kong ~ # killall ptp4l phc2sys
ptp4l: no process found
phc2sys: no process found
Here is my config:
kong ~ # cat ptp.conf
[global]
clock_servo linreg
Start ptp4l:
kong ~ # ptp4l -i eth0 -l 7 -m -f ptp.conf &
And drop the bomb:
kong ~ # phc2sys -a -r -E ntpshm -m -M 2
phc2sys[354.145]: uds: sendto failed: No such file or directory
This one is odd, is uds_address not defaulted as documented?
Sadly, add uds_address /var/run/ptp4l to my ptp.conf does not change
anything.
