stm32f107+dm9161的phy芯片报错eth硬件初始化失败

[tocm] ## 硬件软件配置： - 主控芯片：stm32f107VCT6 - phy芯片：DM9161AEP - 系统版本：4.0.2 - LwIP版本：2.0.2 ## 操作的步骤： - ①新建 RT-Thread 完整版项目 - ②board.h中定义 BSP_USING_ETH 和 PHY 相关的宏 - ③board.c中初始化 ETH 相关的引脚和时钟 - ④stm32xxxx_hal_config.h中打开 HAL 库函数对 ETH 的支持 - ⑤board.c 中实现自己的 PHY 复位函数（复位函数为空） - ⑥配置 lwIP 协议栈 ## 运行产生错误： ``` [E/drv.emac] eth hardware init failed ``` 麻烦大佬指定下，感谢感谢！ 主要是操作的第③步骤，用stm32cubeMX配置eth的硬件关键生成的HAL_ETH_MspInit如下。 ```c void HAL_ETH_MspInit(ETH_HandleTypeDef* heth) { GPIO_InitTypeDef GPIO_InitStruct = {0}; if(heth->Instance==ETH) { /* USER CODE BEGIN ETH_MspInit 0 */ /* USER CODE END ETH_MspInit 0 */ /* Peripheral clock enable */ __HAL_RCC_ETH_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); __HAL_RCC_GPIOD_CLK_ENABLE(); /**ETH GPIO Configuration PC1 ------> ETH_MDC PA1 ------> ETH_REF_CLK PA2 ------> ETH_MDIO PB11 ------> ETH_TX_EN PB12 ------> ETH_TXD0 PB13 ------> ETH_TXD1 PD8 ------> ETH_CRS_DV PD9 ------> ETH_RXD0 PD10 ------> ETH_RXD1 */ GPIO_InitStruct.Pin = GPIO_PIN_1; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; HAL_GPIO_Init(GPIOC, &GPIO_InitStruct); GPIO_InitStruct.Pin = GPIO_PIN_1; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); GPIO_InitStruct.Pin = GPIO_PIN_2; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); GPIO_InitStruct.Pin = GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_13; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct); GPIO_InitStruct.Pin = GPIO_PIN_8|GPIO_PIN_9|GPIO_PIN_10; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOD, &GPIO_InitStruct); __HAL_AFIO_REMAP_ETH_ENABLE(); /* USER CODE BEGIN ETH_MspInit 1 */ /* USER CODE END ETH_MspInit 1 */ } } ``` -------------------------------------------------------- 用stm32cubeMX配置成如下  -------------------------------------------------------- stm32f107的接线图 --------------------------------------------------------  -------------------------------------------------------- DM9161AEP的接线图 --------------------------------------------------------  详细的运行log ``` \ | / - RT - Thread Operating System / | \ 4.0.2 build Aug 12 2020 2006 - 2019 Copyright by rt-thread team lwIP-2.0.2 initialized!

muc rmii 接口 驱动phy芯片不工作。先看phy晶振是否起振了，然后再检查mcu ref clk是否有50M时钟输入了。 再看看mdio读写寄存器phy的ID是不是手册上的值。一步步来就能排查出

你这个很难判断，可以用断点方式进行调试，先找到fail的位置

这个问题我碰到过，log也是显示`[D/drv.emac] phy basic status reg is 0x7849`。这个需要改写`phy_linkchange()`。 我之前用的是`Marvell 88E6060`。`phy_linkchange`原检测的是BSR寄存器，我改成SSR寄存器，或者交换机的寄存器，就可以了，插拔能正常识别linkstatus以及全双工和speed检测都正常。
