Network clock

100jade over 9 years ago

Hello,

I'm looking for an example or documentation on how to use/access the network clock in a hardware design. Is there any information available?

Hi Jan,
Sorry I didn't notice your response asking this question on your other post. I found some documentaion/forum posts that should get you going.

Hi Josh,
thanks for the links! That is interesting information. I build my own Linux with Yocto and it has LinuxPTP installed. So it seems the drivers are there. At least the output from ethtool -T eth0 is promising.
What I miss now is information on how to use the network clock in programmable logic (PL). I could not find anything in the PL library. I found the example in emacps, but that is PS. Is there something for PL available? What do I have to look for?
Thanks
Jan
