[STM32]drv_eth.c在H7系列报错

[CharlesXSong]

初始化函数rt_stm32_eth_init

rt_stm32_eth_init初始化EthHandle时的代码如下：

    __HAL_RCC_ETH_CLK_ENABLE();

    phy_reset();

    /* ETHERNET Configuration */
    EthHandle.Instance = ETH;
    EthHandle.Init.MACAddr = (rt_uint8_t *)&stm32_eth_device.dev_addr[0];
    EthHandle.Init.AutoNegotiation = ETH_AUTONEGOTIATION_DISABLE;
    EthHandle.Init.Speed = ETH_SPEED_100M;
    EthHandle.Init.DuplexMode = ETH_MODE_FULLDUPLEX;
    EthHandle.Init.MediaInterface = ETH_MEDIA_INTERFACE_RMII;
    EthHandle.Init.RxMode = ETH_RXINTERRUPT_MODE;
#ifdef RT_LWIP_USING_HW_CHECKSUM
    EthHandle.Init.ChecksumMode = ETH_CHECKSUM_BY_HARDWARE;
#else
    EthHandle.Init.ChecksumMode = ETH_CHECKSUM_BY_SOFTWARE;
#endif

    HAL_ETH_DeInit(&EthHandle);

然而，在bsp\stm32\libraries\STM32H7xx_HAL\STM32H7xx_HAL_Driver\Inc\stm32h7xx_hal_eth.h中关于该句柄Init成员ETH_InitTypeDef Init; /*!< Ethernet Init Configuration */的定义如下：

typedef struct
{

  uint8_t                     *MACAddr;                  /*!< MAC Address of used Hardware: must be pointer on an array of 6 bytes */

  ETH_MediaInterfaceTypeDef   MediaInterface;            /*!< Selects the MII interface or the RMII interface. */

  ETH_DMADescTypeDef          *TxDesc;                   /*!< Provides the address of the first DMA Tx descriptor in the list */

  ETH_DMADescTypeDef          *RxDesc;                   /*!< Provides the address of the first DMA Rx descriptor in the list */

  uint32_t                    RxBuffLen;                 /*!< Provides the length of Rx buffers size */

}ETH_InitTypeDef;

可以看到驱动代码初始化的属性和H7对应的结构体成员不匹配，导致在H7中使用LWIP和ETH功能时报错

rt_stm32_eth_tx和rt_stm32_eth_rx也会因为没有EthHandle.TxDesc等成员与之对应而报错： bsp\stm32\libraries\STM32H7xx_HAL\STM32H7xx_HAL_Driver\Inc\stm32h7xx_hal_eth.h

可以参考一下 stm32H750-artpi 的处理方式
