stm32f429+RW007 初始化一直失败？？？

发布于 2020-10-20 16:38:51 浏览：1868 订阅该版

硬件使用的ALIENTEK的F429核心板，底板是自己画的板子
RW007在SPI4上总线上挂载
spi4通过cubmux配置IO口，KCONFIG里也修改了，list_device里也有spi4设备
初始化一直失败，感觉是SPI初始化的有问题，请大家帮我看看
SPI4 IO口配置（cubmux生成的）

  /* USER CODE END SPI4_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_SPI4_CLK_ENABLE();
    __HAL_RCC_GPIOE_CLK_ENABLE();
    /**SPI4 GPIO Configuration    
    PE2     ------> SPI4_SCK
    PE5     ------> SPI4_MISO
    PE6     ------> SPI4_MOSI 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_2|GPIO_PIN_5|GPIO_PIN_6;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI4;
    HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
