Fantastic project.

that's so good, anybody have a guide?

The leading PTP for linux, for good reason!

I am using the latest version 1.9.2 of linuxptp wherein , I am combining the NTP as well as PTP sources using timemaster program in the client machine running RHEL 7.1. I am facing issues w.r.t the time source selection. I have 1 PTP source and 3 NTP sources. Whenever all 4 sources are present and working, the local clock gets synchronized with the PTP master but as soon as I make the PTP master offline, the timemaster service does not switch to any of NTP sources and always indicates that it is synced to PTP, which is false . I have tested this for continuous 24 hours of operation. However , when I restart the timemaster service, it gets synchronized with the best NTP server. So every time, I have to restart the timemaster service when the PTP master fails. looking forward for a solution and possible configuration change if required.

Very good HW TS synchronization on all the Freescale and TI platforms we have tested

Excuse me, I want to install your linuxptp on either Ubuntu(PC) or Angstrom(embedded system). (one for master and another for slave) But I don't know what the Step 6.1 about Linux kernel means in your website, "It is important to have the kernel headers available when compiling the Linux PTP stack." If I use a kernel version upper than 3.8, should I do any work to kernel header? I don't really know how Linux kernel works, so the Step 6.1 is for a custom kernel to do with? Thanks!
