Hi,
I've found three bugs in CubeMX for the DCMI code generation.
uC: STM32H7A3IITxQ
CubeMX Version: 6.5.0
Firmware Package: STM32Cube FW_H7 V1.10.0
The IOC-file is attached.
1.Following lines are getting generated in HAL_DCMI_MspDeInit:
HAL_DMA_DeInit(dcmiHandle->DMA_Handle);
HAL_DMA_DeInit(dcmiHandle->hdmarx);
HAL_DMA_DeInit(dcmiHandle->hdmatx);
=> The dcmiHandle has no members named "hdmarx" and "hdmatx". (Compile Error)
2.Following lines are getting generated in HAL_DCMI_MspInit:
__HAL_LINKDMA(dcmiHandle,DMA_Handle,hdma_dcmi_pssi);
__HAL_LINKDMA(dcmiHandle,hdmarx,hdma_dcmi_pssi);
__HAL_LINKDMA(dcmiHandle,hdmatx,hdma_dcmi_pssi);
=> Same thing here, "hdmarx" and "hdmatx" are no members of the dcmiHandle. (Compile Error)
3.In the main function, following lines are getting generated:
MX_GPIO_Init();
MX_FMC_Init();
MX_DCMI_Init();
MX_DMA2D_Init();
MX_LTDC_Init();
MX_TIM2_Init();
MX_I2S1_Init();
MX_I2C1_Init();
MX_I2C2_Init();
MX_SPI2_Init();
MX_CRC_Init();
MX_DMA_Init();
MX_JPEG_Init();
MX_TIM7_Init();
MX_TouchGFX_Init();
=> MX_DMA_Init() has to be called before MX_DCMI_Init(), else the DCMI-Peripheral isn't working.
Two years ago, someone reported the same problem: https://community.st.com/s/question/0D50X0000BvhrT2SQI/why-do-i-get-overrun-error-when-using-dcmi?t=1648534322363
Hope this get's fixed soon, as I have to change these lines everytime i regenerate the code with CubeMX.
