[Linuxptp-users] Need help : new to PTP testing

[Rayagond K. <ray...@gm...>]

Hi All,

I am new to PTP implementation and testing.

So far I have done following with the help of Linux doc and browsing (
http://linuxptp.sourceforge.net/),

1. I referred Linux doc and reference driver and implemented PTP V1 and V2
in MAC driver - MAC driver is able to handle PTP packets, it can pass the
transmitted/received packets timestamp value to stack.

2. I am able to write PTP Hardware Clock (PHC) driver and integrate with my
MAC driver - Through PHC driver I have registered all the clock API's like
gettime/settime/adjtime etc to ptp clock driver or ptp stack. My MAC has
internal clock source, so I am registering the PHC driver as part of MAC
driver itself.

3. I build Linux kernel with version 3.1.1 and enabled all the PTP related
kernel configurations like CONFIG_PPS, CONFIG_NETWORK_PHY_TIMESTAMPING and
PTP_1588_CLOCK.

4. After loading MAC driver I can see /dev/ptp0 entry for my PHC driver.

5. For testing PTP, I downloaded the ptp application from -  git clone
git://git.code.sf.net/p/linuxptp/code, and compiled the ptp it and
installed in my system. Now I can run the ptp application.

6. I ran following commands ...

$ptp4l -i eth0 -p /dev/ptp0

ie I choose my system ad PTP master and it is sending the SYNC messages and
all.

I am not getting how to use -f option and what is the configuration file
etc.

I don't have clear idea on how to test the PTP, please give me some
suggestions to go ahead.

Thank you all in advance for any help.
