Hi, In our setup, when the grandmaster reboots, the ptp slave gets out of sync and is unable to resync again. The ptp slave shows a huge offset once the grandmaster comes back up and it remains like this. When I set the step_threshold parameter to 0.00002, the offset reduces but the port state stays in UNCALIBRATED state and is unable to switch to RS_SLAVE state. On further increasing the step_threshold parameter to 0.02, the ptp slave is able to resync with the master and switch to RS_SLAVE state easily. I am confused about what is going on here. Why didn't 0.00002 worked but 0.02 did.
Another thing I am a bit confused about is first_step_threshold. In the manpage it says, The maximum offset the servo will correct by changing the clock frequency instead of stepping the clock. This is only applied on the first update. I would like to know what does "first update" mean in this context. Thanks for your time. Best regards, Jawad
