Re: [Linuxptp-users] Interesting (very wrong) PTP output

[Keller, J. E <jac...@in...>]

I found the bug in my driver: the time increment register was being zeroed by a reset path, and I wasn't properly resetting it, so the ptp daemon was unable to sync to it as master because the other end has a clock that wasn't changing.

This was the cause of the problems.
