有没有APM32F107RC以太网问题
开发板用的的是PD8、PD9、PD10复用引脚，我板子上用的是PA7、PC4、PC5不管怎么调就是不好使，确认PHY正常运行通过MDIO可以读取到PHY状态，以下是初始化代码：voidEthernet_GPIOConfig(void){GPIO_Config_TconfigStruct;/**ETH_RESET#PB15*ETH_INTPB14*ETH_MDIOPA2*ETH_MDCPC1*ETH_MCOPA8*//*EnableGPIOsclocks*/RCM_EnableAPB2PeriphClock(ETH_MDC_GPIO_CLK|ETH_MDIO_GPIO_CLK|ETH_RESET_GPIO_CLK|ETH_INT_GPIO_CLK|ETH_MCO_GPIO_CLK);/*EnableSYSCFGclock*/RCM_EnableAPB2PeriphClock(RCM_APB2_PERIPH_AFIO);/*ConfigureETH_RESET#*/GPIO_ConfigStructInit(&configStruct);configStruct.pin=ETH_INT_PIN;configStruct.speed=GPIO_SPEED_50MHz;configStruct.mode=GPIO_MODE_OUT_PP;GPIO_Config(ETH_RESET_PORT,&configStruct);/*ConfigureETH_MII_INT*/configStruct.pin=ETH_INT_PIN;GPIO_Config(ETH_INT_PORT,&configStruct);ETH_INT_PIN_HIGH();/*ConfigureETH_MDC*/configStruct.pin=ETH_MDC_PIN;configStruct.mode=GPIO_MODE_AF_PP;GPIO_Config(ETH_MDC_PORT,&configStruct);/*ConfigureETH_MDIO*/configStruct.pin=ETH_MDIO_PIN;GPIO_Config(ETH_MDIO_PORT,&configStruct);/*RESETETHPHY*/ETH_RESET_PIN_LOW();Ethernet_ResetDelay(DP83848_RESET_DELAY);ETH_RESET_PIN_HIGH();Ethernet_ResetDelay(DP83848_RESET_DELAY);/*ConfigurePB10,PB11,PB12,PB13asalternatefunctionpush-pull*/configStruct.pin=GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_13;GPIO_Config(GPIOB,&configStruct);/**ETH_RMII_REF_CLKPA1*ETH_RMII_CRS_DVPD8->PA7*ETH_RMII_RXD0PD9->PC4*ETH_RMII_RXD1PD10->PC5*ETH_RMII_TX_ENPB11*ETH_RMII_TXD0PB12*ETH_RMII_TXD1PB13*//*EnableGPIOsclocks*/RCM_EnableAPB2PeriphClock(RCM_APB2_PERIPH_GPIOA|RCM_APB2_PERIPH_GPIOB|RCM_APB2_PERIPH_GPIOC|RCM_APB2_PERIPH_GPIOD);/*ETHERNETpinsremappinAPM32107
