Re: [Linuxptp-users] PTP on Davinci(TI81xx)

[<sur...@wi...>]

Hi,

 We are refering to this website where it is suggested to use linuxptp for TI boards

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/p/204024/859216.aspx#859216

Linuxptp web tells that davinci TI board is supported.
 http://linuxptp.sourceforge.net/
---------------------------------------------------------------------------
davinci_emac	TI DaVinci, Sitara	SW	N	Y	3.1
----------------------------------------------------------------------------


We are trying to sync the PTP clock on boards.


Thanks and Regards
Suresh

Which SoC is it exactly and which kernel (compiled from which source repository/branch) are you using?

What are the URLs of the relevant wiki pages?

linuxptp's command line options look OK to me (of course that depends on what you are trying to do). There is a problem with packet timestamping though.
