[Linuxptp-users] Time stamping over RNDIS (ethernet-over-USB)

[Samuel-EXT, J. <jer...@co...>]

Hello,

I want to synchronize clocks between two nodes communicating by RNDIS. Since the USB driver does not handle HW clock, I configured ptp4l to use SW time stamping.

I do see that the slave receive the PTP messages but I do not see the system clocks converging

On the contrary they diverge : 10 min in one night with ptp4l running

Yesterday:

Thanks for the help,
