DP83867IR: RGMII TX Delay Setting Variation Between Boards

Part Number: DP83867IR

Dear Specialists,

My customer is encountering packet loss issue.

It can be solved by adjusting RGMII TX DELAY CTRL but optimal setting varies from board to board.

I would be grateful if you could advise.

The customer would like to communicate offline.

Could you please send  a friendship request.

I appreciate your great help in advance.

Best regards,

Shinichi
