DP83867IR: DP83867IR issue from Inspur

Part Number: DP83867IR

Hello team,

Customer use the IT part, PHY chip, DP83867IR. However, there is an issue occur on their PFGA board. ”This is urgent case.

Kindly help us to clarify this issue.

1.       Auto-negotiation – Passed, the DUT could get 1Gbps/100Mbps/10Mbps accordingly.

2.       Dynamic IP – Failed, our fine worked DHCP server didn’t get requested packet from DUT client. DUT represented “sending discover” message…

3.       TCP/IP – Passed when FPGA be server and computer be client, when use static IP. Server and client side can be assessed, including 1Gbps/100Mbps/10Mbps.

4.   TCP/IP – Failed when FPGA be client and computer be server, when use static IP. Server and client side can be assessed, including 1Gbps/100Mbps/10Mbps.(UDP will pass)

 

Or could you help to review our schematic. Thanks.

 Regards,

Antony

  • Hi Antony,

    We support the PHY in this forum. It looks like you've shown the PHY in layer 1 is operational as layer 4 is passing, but layer 5 is failing.

    I would recommend getting assistance from the people responsible for the IP stack or OS on the FPGA board.

    Best Regards,
