[I350-T4] (repost) Is it allowed us to use pps through SDP?

ymha — Fri, 10 Mar 2023 15:19:38 GMT

Hi,

I have been using a system with Jetson Xavier AGX (developer kit board with ubuntu 20.04) and a NIC based on the Intel I350-T4 chipset. I would like to receive the reference schematic of the chipset, enable and capture pps (pulse per second) of the NIC, and test performance of the NIC for the IEEE 1588 synchronization.

Could you please provide information about the below?

- requirement for obtaining the schematic,

- support of a device driver of the Ubuntu 20.04 for the Jetson Xavier AGX for enabling pps of the NIC,

- and accessible physical pin(s) or pinmap to capture the pps (NIC product name: aswinipc LX4-350 based on the Intel I350-T4).

Thank you in advance.

Best Regards,

Youngmok Ha

Hello YMHA,

Thank you for posting in Intel Ethernet Communities.

You may refer this link for the datasheet of I350 series:

https://www.intel.com/content/www/us/en/content-details/333171/intel-ethernet-controller-i350-datasheet.html

For the schematic and pinmap, please refer this link below to post this question to embedded community
https://community.intel.com/t5/Embedded-Connectivity/bd-p/embedded-networking-connectivity

To enable PPS (Pulse Per Second) on the NIC (Network Interface Card) of the Jetson Xavier AGX, you will need to install a device driver that supports PPS. One possible driver that you can use is the ptp_kvm driver, which is included in the Ubuntu 20.04 kernel.

Since you mentioned this is a repost, I think the solution might provided from the previous communities post.
