STM32H7232ZG CORDIC DMA code generation issue

[beauwilmink]

I would like to file a bug report for STM32CubeMX.

During configuration of CORDIC using DMA, I have found the following issue:

In:

void HAL_CORDIC_MspInit(CORDIC_HandleTypeDef* hcordic)
{
  if(hcordic->Instance==CORDIC)
  {
    /* USER CODE BEGIN CORDIC_MspInit 0 */

    /* USER CODE END CORDIC_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_CORDIC_CLK_ENABLE();

    /* CORDIC DMA Init */
    /* CORDIC_WR Init */
    hdma_cordic_wr.Instance = DMA1_Stream0;
    hdma_cordic_wr.Init.Request = DMA_REQUEST_CORDIC_WRITE;
    hdma_cordic_wr.Init.Direction = DMA_MEMORY_TO_PERIPH;
    hdma_cordic_wr.Init.PeriphInc = DMA_PINC_DISABLE;
    hdma_cordic_wr.Init.MemInc = DMA_MINC_ENABLE;
    hdma_cordic_wr.Init.PeriphDataAlignment = DMA_PDATAALIGN_WORD;
    hdma_cordic_wr.Init.MemDataAlignment = DMA_MDATAALIGN_WORD;
    hdma_cordic_wr.Init.Mode = DMA_NORMAL;
    hdma_cordic_wr.Init.Priority = DMA_PRIORITY_LOW;
    hdma_cordic_wr.Init.FIFOMode = DMA_FIFOMODE_DISABLE;
    if (HAL_DMA_Init(&hdma_cordic_wr) != HAL_OK)
    {
      Error_Handler();
    }

    __HAL_LINKDMA(hcordic,hdmaOut,hdma_cordic_wr);

    /* CORDIC_RD Init */
    hdma_cordic_rd.Instance = DMA1_Stream1;
    hdma_cordic_rd.Init.Request = DMA_REQUEST_CORDIC_READ;
    hdma_cordic_rd.Init.Direction = DMA_PERIPH_TO_MEMORY;
    hdma_cordic_rd.Init.PeriphInc = DMA_PINC_DISABLE;
    hdma_cordic_rd.Init.MemInc = DMA_MINC_ENABLE;
    hdma_cordic_rd.Init.PeriphDataAlignment = DMA_PDATAALIGN_WORD;
    hdma_cordic_rd.Init.MemDataAlignment = DMA_MDATAALIGN_WORD;
    hdma_cordic_rd.Init.Mode = DMA_NORMAL;
    hdma_cordic_rd.Init.Priority = DMA_PRIORITY_LOW;
    hdma_cordic_rd.Init.FIFOMode = DMA_FIFOMODE_DISABLE;
    if (HAL_DMA_Init(&hdma_cordic_rd) != HAL_OK)
    {
      Error_Handler();
    }

    __HAL_LINKDMA(hcordic,hdmaIn,hdma_cordic_rd);

    /* USER CODE BEGIN CORDIC_MspInit 1 */

    /* USER CODE END CORDIC_MspInit 1 */

  }

}

The DMA streams are linked to the wrong DMA handles, I had to manually adjust the following to get the CORDIC working with DMA:

__HAL_LINKDMA(hcordic,hdmaOut,hdma_cordic_wr); -> __HAL_LINKDMA(hcordic,hdmaIn,hdma_cordic_wr);

and:

__HAL_LINKDMA(hcordic,hdmaIn,hdma_cordic_rd); ->     __HAL_LINKDMA(hcordic,hdmaOut,hdma_cordic_rd);

This issue happens when generating code using STM32CubeMX version 6.14.0. The issue can be reproduced by simply creating a project for the NUCLEO-H723ZG, initializing the CORDIC with the write and read DMA streams enabled and then generating the code. 

Note: The CORDIC_Sin_DMA example shows the correct HAL_CORDIC_MspInit function. This example was used to pinpoint why the CORDIC wasn't working in a newly created project.
