Re: [Linuxptp-users] can't get linux PTP to run

[<Tim...@de...>]

I'm not on kernel 3.9 maybe that's why I get the 25usec offset. 
My master clock is using hardware time stamping with kernel 3.2 (with RT support) and the patched e1000e driver. (http://sourceforge.net/projects/e1000/files/e1000e%20stable/)

What offset do you get and how do you measure it? Maybe I do get the error because of my way to measure the offset.

Today I tried my 82574 card with kernel 3.9-rc2 and the lastest ptp4l, and it seems to be working fine. Perhaps the 25 usec offset error you see is because your master clock is using software time stamping?

HTH,
