Make sure your ptp4l has these five patches: a082bcd clockcheck: Increase minimum interval. 6df8425 port: Don't renew raw transport. e117e37 port: Don't check timestamps from non-slave ports. 262a49b clock: Reset clock check on best clock/port change. 7e8eba5 clock: Reset state when switching port with same best clock. If that doesn't fix the problem, then: 2. Disable clock sanity check. sanity_freq_limit The maximum allowed frequency offset between uncorrected clock and the system monotonic clock in parts per billion (ppb). This is used as a sanity check of the synchronized clock. When a larger offset is measured, a warning message will be printed and the servo will be reset. When set to 0, the sanity check is dis‐ abled. The default is 200000000 (20%). |
