Hello every one,

I have a few issues with Ethernet of STM32F107VC, I used external 25MHz and my code

https://drive.google.com/drive/folders/0B_pYftFJNE1IRjdtOTlSZG5ma0U

I connected STM to DP8384 as below:  - ETH_MII_MDIO / ETH_RMII_MDIO: PA2  - ETH_MII_MDC / ETH_RMII_MDC: PC1\  - ETH_MII_TX_EN / ETH_RMII_TX_EN: PB11  - ETH_MII_TXD0 / ETH_RMII_TXD0: PB12  - ETH_MII_TXD1 / ETH_RMII_TXD1: PB13  - ETH_MII_RX_CLK / ETH_RMII_REF_CLK: PA1- PA8=> Connected with X1 DP8384  - ETH_MII_RX_DV / ETH_RMII_CRS_DV: PD8  - ETH_MII_RXD0 / ETH_RMII_RXD0: PD9  - ETH_MII_RXD1 / ETH_RMII_RXD1: PD10I build my code no error but It do not run...Can you (guy) write for me a code example?Please help me...I am waiting.....

Hi duy.tran,

DP83848 is used in the ETHERNET examples available in the CubeF1 package.You find them under STM32Cube_FW_F1_V1.2.0\Projects\STM3210C_EVAL\Applications\LwIP.If you check the file ethernetif.c, you will see this comment regarding the Ethernet pins configuration:  - ETH_MII_MDIO / ETH_RMII_MDIO: PA2  - ETH_MII_MDC / ETH_RMII_MDC: PC1  - ETH_MII_TXD2: PC2  - ETH_MII_TX_EN / ETH_RMII_TX_EN: PB11  - ETH_MII_TXD0 / ETH_RMII_TXD0: PB12  - ETH_MII_TXD1 / ETH_RMII_TXD1: PB13  - ETH_MII_PPS_OUT / ETH_RMII_PPS_OUT: PB5  - ETH_MII_TXD3: PB8     - ETH_MII_CRS CRS: PA0  - ETH_MII_RX_CLK / ETH_RMII_REF_CLK: PA1  - ETH_MII_COL: PA3  - ETH_MII_RX_DV / ETH_RMII_CRS_DV: PD8  - ETH_MII_TX_CLK: PC3  - ETH_MII_RXD0 / ETH_RMII_RXD0: PD9  - ETH_MII_RXD1 / ETH_RMII_RXD1: PD10  - ETH_MII_RXD2: PD11  - ETH_MII_RXD3: PD12  - ETH_MII_RX_ER: PB10 -Mayla-
