STM32H7A3 DCMI, CubeIDE generates faulty DCMI.c with wrong DMA initialization

[Johannes]

I use CubeIDE 1.9.0

MCU packate STM32H7 V1.10.0

My project generates separate files for each hardware. In this case "dcmi.c" and "dcmi.h"

DCMI is set to Slave 10 bits External Synchro

I use DCMI_PSSI DMA1 Stream 2 Perpheral to Memory

CubeIDE generates following lines in HAL_DCMI_MspInit

  __HAL_LINKDMA(dcmiHandle,hdmarx,hdma_dcmi_pssi);

  __HAL_LINKDMA(dcmiHandle,hdmatx,hdma_dcmi_pssi);

Both of these lines fail with

../Core/Src/dcmi.c:161:5: note: in expansion of macro '__HAL_LINKDMA'
  161 |     __HAL_LINKDMA(dcmiHandle,hdmarx,hdma_dcmi_pssi);
      |     ^~~~~~~~~~~~~
../Drivers/STM32H7xx_HAL_Driver/Inc/stm32h7xx_hal_def.h:65:43: error: 'DCMI_HandleTypeDef' {aka 'struct __DCMI_HandleTypeDef'} has no member named 'hdmatx'
   65 |                               (__HANDLE__)->__PPP_DMA_FIELD__ = &(__DMA_HANDLE__); \

What is the correct way of handling this?

For now, I just comment these lines out. DMA seems to work...

dcmi.c

   /* Several peripheral DMA handle pointers point to the same DMA handle.
     Be aware that there is only one channel to perform all the requested DMAs. */
    __HAL_LINKDMA(dcmiHandle,DMA_Handle,hdma_dcmi_pssi);
    //__HAL_LINKDMA(dcmiHandle,hdmarx,hdma_dcmi_pssi);
    //__HAL_LINKDMA(dcmiHandle,hdmatx,hdma_dcmi_pssi);

Is this a bug in FW-Package?

Is "commenting out" the correct workaround?

Thanks for your help

Hi @Johannes​ ,

That looks like an issue with STM32CubeMX generated code.

@Sara BEN HADJ YAHYA​ do you confirm it?

Hello @Johannes​ ,

Thanks for your feedback,

These three lines are generated whereas the Request is for DCMI IP or for PSSI IP . A specific comment is added to inform that only one LINK will be useful.

* Several peripheral DMA handle pointers point to the same DMA handle.
     Be aware that there is only one channel to perform all the requested DMAs. */
    __HAL_LINKDMA(hpssi,DMA_Handle,hdma_dcmi_pssi);
    __HAL_LINKDMA(hpssi,hdmarx,hdma_dcmi_pssi);
    __HAL_LINKDMA(hpssi,hdmatx,hdma_dcmi_pssi);

The needed request should be kept and the others should be commented as you did. Please make sure to comment the unneeded lines each time you re-generate the code.

I submitted a ticket to the dev team to see if they can change the code generation and keep only the needed DMA request. I will keep you posted.

Hello @Johannes​ ,

This issue is fixed in STM32CubeMX latest release.

V6.7.0 is now available under this Link.

Thanks for your contribution :smiling_face_with_smiling_eyes:

Hello, 

I am using V6.9.0. However, still encountering problem that occurs during initialization from CUBEMX. Following lines are generate the error. 

 /* DCMI DMA DeInit */
HAL_DMA_DeInit(hdcmi->DMA_Handle);
HAL_DMA_DeInit(hdcmi->hdmarx);
HAL_DMA_DeInit(hdcmi->hdmatx);

Error code is: 
../Core/Src/stm32h7xx_hal_msp.c: In function 'HAL_DCMI_MspDeInit':
../Core/Src/stm32h7xx_hal_msp.c:226:25: error: 'DCMI_HandleTypeDef' has no member named 'hdmarx'
226 | HAL_DMA_DeInit(hdcmi->hdmarx);
| ^~
../Core/Src/stm32h7xx_hal_msp.c:227:25: error: 'DCMI_HandleTypeDef' has no member named 'hdmatx'
227 | HAL_DMA_DeInit(hdcmi->hdmatx);
| ^~

 After commenting lines that generate the error, DCMI is somehow works but other code blocks are not working. I there another solution beyond updating CubeMx or commenting those lines?
