I have a custom board which is configured exactly as the DP83867E EVK in snlu209.pdf, as far as PHY, Magnetics, and RJ45. I have established MDIO communication using an FPGA, and can read and write registers. I need to configure the board for SGMII operation, fixed 1Gbps. Please confirm that Port Mirroring should be enabled, as the EVK (and therefore our custom board) have
PHY TD_A going to Magnetics TD4
PHY TD_B going to Magnetics TD3
PHY TD_C going to Magnetics TD2
PHY TD_D going to Magnetics TD1
I am programming registers
0x0000 = 0x0140
0x0009 = 0x0300
0x0010 = 0x5848
0x0011 = 0xA802
0x0014 = 0x2903
0x0031 = 0x0001 (using extended addressing)
But I do not get a link on the MD side.
