基于野火霸道 野火_F429挑战者 实现 spiflash 文件系统   W25Q256

一、STM32CubeMX 配置   

fats

二 代码 ：

 1，开启串口1终端

void HAL_UART_MspInit(UART_HandleTypeDef* huart)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  if(huart->Instance==USART1)
  {
  /* USER CODE BEGIN USART1_MspInit 0 */

  /* USER CODE END USART1_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_USART1_CLK_ENABLE();

    __HAL_RCC_GPIOA_CLK_ENABLE();
    /**USART1 GPIO Configuration
    PA9     ------> USART1_TX
    PA10     ------> USART1_RX
    */
    GPIO_InitStruct.Pin = GPIO_PIN_9|GPIO_PIN_10;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF7_USART1;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

    /* USART1 interrupt Init */
    HAL_NVIC_SetPriority(USART1_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(USART1_IRQn);
  /* USER CODE BEGIN USART1_MspInit 1 */
	__HAL_UART_ENABLE_IT(huart, UART_IT_RXNE);
  /* USER CODE END USART1_MspInit 1 */
  }

}

2，串口终端接收

void USART1_IRQHandler(void)
{
  /* USER CODE BEGIN USART1_IRQn 0 */
	//½ÓÊÕÊý¾Ý
	HAL_UART_Receive(&huart1, pRx_Data, 1, 1000);//  
}

3，调试信息输出

/* USER CODE BEGIN 0 */
int fputc(int ch, FILE* FILE)
{
    HAL_UART_Transmit(&huart1, (uint8_t*)&ch, 1, HAL_MAX_DELAY);
    return ch;
}
/* USER CODE END 0 */

4、挂载文件系统 

// HAL_Delay(1000);
    printf("system is booting\r\n");

   // printf("****** ²Á³ýSPI_FLASH ÉÈÇø0 ******\r\n");
   // BSP_W25Q256_Erase_Sector(0);
    //HAL_Delay(1000);
    /*----------------------- ¹ÒÔزâÊÔ ---------------------------*/
    printf("****** SPI FLASH ÎļþϵͳÆô¶¯ÖÐ******\r\n");
    res = f_mount(&spi_fs, "0:", 1);
    if(res != FR_OK)
    {
        if(res == FR_NO_FILESYSTEM)
        {
            printf("f_mount ûÓÐÎļþϵͳ,¿ªÊ¼¸ñʽ»¯spi-flash\r\n");
            res = f_mkfs("0:", FM_ANY, 0, &work, 4096);
            if(res != FR_OK)
            {
                printf("f_mkfs ¸ñʽ»¯Ê§°Ü£¬err = %d\r\n", res);
                while(1);
            }
            else
            {
                printf("¸ñʽ»¯³É¹¦£¬¿ªÊ¼ÖØйÒÔØspi-flash\r\n");
                res = f_mount(&spi_fs, "0:", 1);
                if(res != FR_OK)
                {
                    printf("f_mount ·¢Éú´íÎó£¬err = %d\r\n", res);
                }
                else printf("spi-flashÎļþϵͳ¹ÒÔسɹ¦\r\n");
            }
        }
        else
        {
            printf("f_mount ·¢ÉúÆäËû´íÎó£¬err = %d\r\n", res);
            while(1);
        }
    }
    else printf("spi-flashÎļþϵͳ¹ÒÔسɹ¦\r\n");
