Configure 1PPS in Ethernet Network Adapter XXV710-DA2T (Intel)

[mvellop]

Saltar a solución

Good afternoon,

I am using two Ethernet Network Adapter XXV710-DA2T in the LAB and I am looking for a manual to configure the PPS because I can not see the PPS out from the SMA port and we have checked all options.

Therefore, to whom may concern, could you please provide a manual to us to configure the PPS at the SMA ports and the boundary clock functionality?

Thanks in advance,

Greetings,

Carmen.

Hello mvellop,

Thank you for posting in Intel Ethernet Communities. 

Before we proceed, let me check if you are designing a board or a system with embedded XXV710-DA2T?

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days.

Thank you.

Hello!!

We would like to design a PTP system. Therefore, we are using two servers with the XXV710-DA2T board in each one and we would want to configure the XXV710-DA2T for timing synchronization between them. So, first of all, our main aim is to have some knowledge about how to configure the PPS OUT/IN in the SMA port and which corresponds to.

Thanks in advance,

Greetings,

Carmen.

Hello, @mvellop:

Thank you for contacting Intel Embedded Community.

Based on your replies, we want to address the following questions:

Could you please clarify if your consultation is related to add-in network cards or Ethernet controllers? In case that it is related to Ethernet controllers, could you please let us know the part numbers? 

Could you please let us know the list of the sources that you used to design the PTP system?

Could you please clarify if this system has been verified by Intel?

We are waiting for your reply to these questions.

Best regards,

@CarlosAM_INTEL.

Hello @CarlosAM_INTEL :

We also want to use these ethernet adapters (XXV710-DA2T) in our setup. We want to use linuxptp and GPS receiver w/ 1PPS output (GPS data to virtual COM port via USB) for this purpose. The OS is - Ubuntu Server 18.04 LTS. The driver: i40e version: 2.15.9, firmware-version: 8.30 0x8000a483 1.2926.0.

Could you please provide the requested information (SMA configuration for 1PPS input and use GPS timestamps for PHC) without asking additional questions?

Thank you!

Hello, @KVladimir:

Thank you for contacting Intel Embedded Community.

You should address as a reference your questions related to the cited driver through the channels listed on the following website:

 https://sourceforge.net/projects/linuxptp/support

Hello, @CarlosAM_INTEL :

Is it correct that linuxptp community should know more about Intel ethernet adapter configuration than Intel Embedded Community?

Actually I've already visited this website and there is no such information. In anyway ptp4l and phc2sys works well with system time but we need to make sure that Intel NIC uses GPS timestamps and 1PPS signal.

I already looked through this spec and many other docs but didn't find how to configure it's pins.

[ChrRaj00]

Hello KVladimir,

have you figured out how to configure the pins? I'm also searching for this information like you.

Thanks,

Christian

[KVladimir]

Hi Christian,

Check /sys/class/ptp/ directory, go into the one you need to configure and then list pins. You can use 'cat' for reading them and 'echo' to modify.

Vladimir
