Posted on June 20, 2018 at 09:31Hello!
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.
