Hello!

        I want to develop a project in which my device will act as TCP/IP client hence I'm about to use STM32F207ZET6, as it supports Ethernet MAC( IEEE 1588v2 hardware, MII/RMII ). I try to search online(datasheet and STM forums). but could't find any specific details  

details of MII/RMMI's pins

so anyone can give me brief description about these pin's usage, advantage(if use), mode(if applicable) etc:

ETH_MDIO            -------------------------> PA2

ETH_MDC             --------------------------> PC1

ETH_PPS_OUT     -------------------------> PB5

ETH_MII_CRS       -------------------------> PH2

ETH_MII_COL       -------------------------> PH3

ETH_MII_RX_ER  -------------------------> PI10

ETH_MII_RXD2    --------------------------> PH6

ETH_MII_RXD3    --------------------------> PH7

ETH_MII_TX_CLK -------------------------> PC3

ETH_MII_TXD2      -------------------------> PC2

ETH_MII_TXD3      -------------------------> PB8

ETH_MII_RX_CLK/ETH_RMII_REF_CLK   -----> PA1

ETH_MII_RX_DV/ETH_RMII_CRS_DV      -----> PA7

ETH_MII_RXD0/ETH_RMII_RXD0             -----> PC4

ETH_MII_RXD1/ETH_RMII_RXD1             -----> PC5

ETH_MII_TX_EN/ETH_RMII_TX_EN        -----> PG11

ETH_MII_TXD0/ETH_RMII_TXD0             -----> PG13

ETH_MII_TXD1/ETH_RMII_TXD1             -----> PG14

mainly I want to know more about:

1) the significant of 

ETH_PPS_OUT and ETH_MII_RX_ER.

2) whether it is necessary to use these two or we can neglect them.

3) if we can't neglect them where exactly I need to connect on the controller embedded with Ethernet interface.

4) and where exactly I can get 

the 

LwIP 

examples under STM32CubeF2 package.

Thanks and Regards.
