/* Configure Ethernet MAC for connection with an RMII PHY */

GPIO_ETH_MediaInterfaceConfig(GPIO_ETH_MediaInterface_RMII);

In F2 series you have to update this code as follows:

/* Configure Ethernet MAC for connection with an MII PHY */

SYSCFG_ETH_MediaInterfaceConfig(SYSCFG_ETH_MediaInterface_MII);

/* Configure Ethernet MAC for connection with an RMII PHY */

SYSCFG_ETH_MediaInterfaceConfig(SYSCFG_ETH_MediaInterface_RMII);

TIM2 internal trigger 1 (ITR1) remapping

The example below shows how to select USB OTG FS SOF output or ETH PTP trigger

output as input for TIM2 ITR1 in STM32 F1 series:

/* Connect USB OTG FS SOF output to TIM2 ITR1 input */

GPIO_PinRemapConfig(GPIO_Remap_TIM2ITR1_PTP_SOF, ENABLE);

/* Connect ETH PTP trigger output to TIM2 ITR1 input */

GPIO_PinRemapConfig(GPIO_Remap_TIM2ITR1_PTP_SOF, DISABLE);

In F2 series you have to update this code as follows:

/* Connect USB OTG FS SOF output to TIM2 ITR1 input */

TIM_RemapConfig(TIM2, TIM2_USBFS_SOF);

/* Connect ETH PTP trigger output to TIM2 ITR1 input */

TIM_RemapConfig(TIM2, TIM2_ETH_PTP);
