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.
