STM32N657B0 Drive the VD55G0

[eureka]

I want to use N657B0 to drive VD55G0, and the camera side can already enter the Stream state. After I use the function HAL_DCMIPP_CSI_PIPE_Start, I track the variable csi_instance through single-step debugging and find that several bits in its SR1 register are inconsistent with the normal state. And I find the defination about these.The normal state is 1 but I get 0.Could you please tell me what the reason for this might be? 

Is the issue caused by a voltage supply problem in the hardware connection, or by inadequate rate matching in the port?

That is my configuration.

Hello,

Could you please first correctly reorder the configuration and share if the problem persists?

static void MX_DCMIPP_Init(void)
{
/* USER CODE BEGIN DCMIPP_Init 0 */
/* USER CODE END DCMIPP_Init 0 */
DCMIPP_CSI_PIPE_ConfTypeDef pCSIPipeConf = {0};
DCMIPP_PipeConfTypeDef PipeConfig = {0};
DCMIPP_CSI_ConfTypeDef csiconf = {0};

/* USER CODE BEGIN DCMIPP_Init 1 */
/* USER CODE END DCMIPP_Init 1 */
phdcmipp.Instance = DCMIPP;

if (HAL_DCMIPP_Init(&phdcmipp) != HAL_OK)
{
Error_Handler();
}

/* Configure the CSI */
csiconf.DataLaneMapping = DCMIPP_CSI_PHYSICAL_DATA_LANES;
csiconf.NumberOfLanes = DCMIPP_CSI_TWO_DATA_LANES;
csiconf.PHYBitrate = DCMIPP_CSI_PHY_BT_250;
HAL_DCMIPP_CSI_SetConfig(&phdcmipp, &csiconf);

/* Set Virtual Channel config */
HAL_DCMIPP_CSI_SetVCConfig(&phdcmipp, DCMIPP_VIRTUAL_CHANNEL0, DCMIPP_CSI_DT_BPP8);

/* Pipe 1 Config */
pCSIPipeConf.DataTypeMode = DCMIPP_DTMODE_DTIDA;
pCSIPipeConf.DataTypeIDA = DCMIPP_DT_RGB565;
pCSIPipeConf.DataTypeIDB = DCMIPP_DT_RGB565;
HAL_DCMIPP_CSI_PIPE_SetConfig(&phdcmipp, DCMIPP_PIPE1, &pCSIPipeConf);

PipeConfig.FrameRate = DCMIPP_FRAME_RATE_ALL;
PipeConfig.PixelPackerFormat = DCMIPP_PIXEL_PACKER_FORMAT_RGB565_1;
PipeConfig.PixelPipePitch = FRAME_WIDTH * 2 ; /* Number of bytes per Line */
if (HAL_DCMIPP_PIPE_SetConfig(&phdcmipp, DCMIPP_PIPE1, &PipeConfig) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN DCMIPP_Init 2 */
/* USER CODE END DCMIPP_Init 2 */
}

Best Regards,

It's still the same error. Is the difference between this code and the one I provided that Pipe0 has been changed to Pipe1? We still can't receive data, and RxActivateHS_lane0 is still 0

 

[Ch_JE]

It was just an example. Surely, you can use pipe0. What I meant was the order or call sequence of the functions

[eureka]

Sorry, I can't understand what you meaning. Do you mean the position of MX_DCMIPP_Init() in main.c?

[Ch_JE]

No I mean the HAL_DCMIPP... Functions calls

[eureka]

However,  when I ran the code you provided earlier, I still couldn't solve that problem, and I still couldn't receive the image.
