Hi anyone:

I found in RM of imx7d, some MII interface PIN is missing or wrong. 

example:

TX_CLK should be use as input ,but in RM it's ouput.

and there is no ENET1_TX_EN pin. 

RGMII_TX_CTL is similar to TX_EN, but it used for RGMII only

Does anyone know the detail of pin assignment for MII interface?

MII interface should contains the following pins:

TXD[0:3] TX_ER TX_CLK/TXC  TX_EN  RXD[0:3] RX_CLK RX RX_XDV COL CRS

1. There is the typo in the manual regarding the ENETx_TX_CLK signal. Actually, it is input in the MII mode.

2. There is the typo in the manual regarding the RGMIIx_TX_CTL signal. Actually, in MII mode it operates as ENETx_TX_EN.


Have a great day,
Artur
