关于STM32F429的SPI的DMA传输问题

配置已经截图，现在是这样，上述配置下，用HAL_SPI_Transmit(&hspi3, txbuff, 1, 1000);发送没有任何问题正常，现在用HAL_SPI_Transmit_DMA(&hspi3, (uint8_t*)txbuff, sizeof(txbuff));或者//      HAL_SPI_TransmitReceive_DMA(&hspi3,(uint8_t*)txbuff,(uint8_t*)rxbuff,(sizeof(txbuff)/sizeof(uint16_t)));这两个函数发送数据，在总线上没有任何数据，也没有任何波形，这是什么原因

我遇到了和你类似的问题，老哥最后解决了吗

我这边最后解决了，是缓存一致性的问题，下面贴一下我包装的发送函数和中断服务程序。
在调用发送函数前调用一下API缓存一致性就好了。
接收时其实并没有出现问题，但还是调了一下



/**
* @brief 启用了DMA功能的SPI，调用发送函数时的分支处理，开启一个发送通道
* @param pd stdio结构体指针
* @param TBuf 期望使用DMA发送的地址头
* @param ui32Len 期望发送的数据长度
* @return 标准返回
*/
static uint32_t SpiDMATransmit(_SPI_STDIO_HANDLE *pd, const uint8_t *TBuf, uint32_t ui32Len)
{
    SCB_CleanDCache_by_Addr((uint32_t *)TBuf, ui32Len); // DMA发送前解决发送内存区 缓存一致性
    if(HAL_SPI_Transmit_DMA(pd->SpiConfig.Spi, TBuf, ui32Len) != HAL_OK)
      return RETURN_ERR_INDEFINITE;

    return RETURN_DEFAULT;
}



/**
* @brief hal中断的接收完成回调
* @param hspi
*/
void HAL_SPI_RxCpltCallback(SPI_HandleTypeDef *hspi)
{
    if(hspi->Instance == SPI5)
    {
      tSpi5.SpiStatus.LineMiso = SPI_LINE_COMPLETE;
      if(tSpi5.SpiConfig.SpiReceiverDma == SPI_DMA_EN) // 开启了DMA，接收完成时解决内存一致性
      {
            SCB_InvalidateDCache_by_Addr((uint32_t *)tSpi5.SpiConfig.Spi->pRxBuffPtr, tSpi5.SpiConfig.Spi->RxXferSize);
      }
    }
}
