What's gPTP timing error between two i210T1 cards?

When using your two i210T1 cards to see their SDP function for gPTP(like PPS), we found a problem: Two SDP pins show over 100ms timing error?

Hello, @3000022607141.5628375056881528E12​:

 

Thank you for contacting Intel Embedded Community.

 

Could you please confirm if your question is related to the Intel(R) Ethernet Server Adapter I210-T1? The information of this device can be found at:

 

https://ark.intel.com/content/www/us/en/ark/products/68668/intel-ethernet-server-adapter-i210-t1.htm...

 

We are waiting for your clarification.

Hi Intel Experts, Thanks for your feedback! Actually, I have already been checking this i210T1’s gPTP timing error issue with “Intel Customer Support” for over one month, so they suggest me directly contact Intel software engineer who is familiar with i210T1’s gPTP&SDP pin function via this Intel Embedded Community Forum. And, before that problematic test result, we already modified i210T1’s Linux driver with gPTP’s SDP pin setting (for PPS function) information from Intel! What I need is: We have an CNDA with Intel, so I need an Intel software engineer who is familiar with i210T1’s gPTP&SDP pin function to directly contact me A.S.A.P. And, I will provide more details for this issue checking after that. Thanks a lot! Many Thanks jerry

Hi Maecenas_INTEL, Please check the attachments for our test result. Thanks! Problem: Why 2 i210T1 show large constant timing error after time sync. works? 1) i210T1 driver: Please find our testing i210T1 driver(igb-5.3.5.22_pps.zip) under following space: <https://drive.google.com/drive/folders/1LDD3l8ST1FWGr6d2VSZ6ORcbG9oICkgV> https://drive.google.com/drive/folders/1LDD3l8ST1FWGr6d2VSZ6ORcbG9oICkgV Note: We downloaded your i210 Linux driver from your website. Then, we added some software codes as page 29~33 of attached IE1588 clock synchronization test_v6.pdf. Please help first check its correctness of SDP setting. Thanks! 2) Test tool and Test setup: For Test tool, we’re using your “An example Intel provided gptp daemon” under <https://github.com/AVnu/gptp> https://github.com/AVnu/gptp. As attached i210T1_SDP_test.doc, the 2 i210T1 cards are directly connected by a short Ethernet cable to test! Many Thanks jerry
