stm32f756 dcmi - no dcmi interrupts

Does DMA complete successfully, or is there any error reported in status register ?

Thanks for your response.

There is no

error

or

a

DMA

or

at

DCMI

I will add

that

I checked

the wiring

Did you correctly clear status flags during the interrupt handler ? (DMA_FLAG_HTIF1 and/or DMA_FLAG_TCIF1)

yes - flags are unset.

I will add

that

I get

dma

interrupt

transfer

complete

at

the

end.

void
DMA2_Stream1_IRQHandler(
void
)
{
BSP_CAMERA_DMA_IRQHandler();
volatile
uint32_t flags = __HAL_DMA_GET_FLAG(hDcmiHandler.DMA_Handle, DMA_FLAG_TCIF1_5 | DMA_FLAG_HTIF1_5 | DMA_FLAG_TEIF1_5 | DMA_FLAG_DMEIF1_5 | DMA_FLAG_FEIF1_5);
if
(flags > 0) {//Never go into

__HAL_DMA_CLEAR_FLAG(hDcmiHandler.DMA_Handle, DMA_FLAG_TCIF1_5 | DMA_FLAG_HTIF1_5 | DMA_FLAG_TEIF1_5 | DMA_FLAG_DMEIF1_5 | DMA_FLAG_FEIF1_5);
}
}

I found the problem. One chip pad had no contact.

I don't understand how you known you are getting TCIF while never having (flag>0), please clarify.

BSP_CAMERA_DMA_IRQHandler

BSP_CAMERA_DMA_IRQHandler

dma not want to work after the one interrupt.

I insert test code to application

.
