[Linuxptp-users] Adding LinuxPTP to Arria 10 SoC

[John L. <joh...@fo...>]

Hello,

 

I am trying to add ptp support into my Altera Arria 10 SoC dev kit
(Cortex-A9).  Eventually I would like to use a 10G MAC with SGDMAs and SFP
port, but for now I am trying to get it working using the ARM HPS Gb-EMAC
and Micrel KSZ9031RN triple speed PHY .  

 

I have built Linux both using Yocto and also my own build from Altera's
LTSI kernel and Buildroot/Busybox for filesystem.  My question is how to
add LinuxPTP to my embedded Linux and add driver bindings to the MAC, etc.
so that I can run as an OC slave?  I have downloaded the LinuxPTP source,
and set my:

 

ARCH=arm

CROSS_COMPILE=CROSS_COMPILE=/localcad/skyfather/ArriaX/ltsi_4_1_33/gcc-lin
aro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-  

 

And then I ran:  make install  which put the output files into
usr/local/sbin   and usr/local/man/man8

 

Can I just copy those directories to my embedded Linux FS and run them?  

 

BTW - 

When I run ethtool -T eth0 to check capabilities I get:

 

Time stamping parameters for eth0:
