STM32N6570-DK MIPI CSI-2 D-PHY Camera Issue

[Nian8113]

Hello teams,

I tried to use STM32N6570-DK DCMIPP Pipe0 to read data from my camera that has own ISP. The camera output format is UYVY (YUV422 BPP16). The issue is that I can't get any data from DCMIPP and CSI-2 Host, I only received SOF and EOF events from CSI-2 Host. I've referred to other people's posts, but my issue still exists. Is my DCMIPP and CSI configuration wrong?

Additionally, I'm not sure if the CSI and DCMIPP clock is set correctly, I just follow the example. If my camera out is 640x480@60fps and format is UYVY, how should I configure this clock?

My settings are as follows.

static void MX_DCMIPP_Init(void)
{

	/* USER CODE BEGIN DCMIPP_Init 0 */

	/* USER CODE END DCMIPP_Init 0 */

	DCMIPP_CSI_PIPE_ConfTypeDef pCSI_PipeConfig = { 0 };

	DCMIPP_PipeConfTypeDef pPipeConfig = { 0 };

	/* USER CODE END DCMIPP_Init 1 */
	hdcmipp.Instance = DCMIPP;
	if (HAL_DCMIPP_Init(&hdcmipp) != HAL_OK) {
		Error_Handler();
	}
