hello,
My board uses DP83867E + FPGA, and my board uses 100M mode to successfully communicate with the computer.
I want to make the board work in RGMII, 1000Mhz, full-duplex mode.
My current situation is that no matter how to configure DP83867E, it will not succeed. When the board is connected to the computer via a network cable, the computer cannot recognize the network connection.
How should I configure to DP83867E, please give me a complete register configuration flow chart. Make sure it can work in RGMII, 1000Mhz, full-duplex mode.
This problem has troubled me for a long time, please help me。
(I can make sure that the RGMII timing is correct, because using my FPGA code can successfully connect to the Ethernet on other chips.)
Regards
