I'm Using Boundary Nitrogen6X Development board.
ENET connection is shown as below:
Physical <==> MII <==> MAC
KSZ9021RN is used in the design.
In the development board, RGMII_TD and RGMII_RD pins are connected to KSZ9021RN as data transfer pins.
BTW, ENET_RX_DATA & ENET_TX_DATA pins remains unused. What is the purpose of ENET_RX_DATA & ENET_TX_DATA in the ENET module?
