ADV7280-M,I want to output Frame Start code and Frame End code of CSI short packet data type code from ADV7280.

    Product Number:  ADV7280ABCPZ-M 
    
    		        		    		    	
			
    I'm connecting the CSI output of the ADV7280 to a Lattice FPGA.
    

    [Contents of question]
    

    As a result of checking the short packet data type code of the FPGA CSI DPHY Receiver IP,Frame Start Code(csi short packet Data type=0x00) and Frame End Code(csi short packet Data type=0x01) of csi data type output each line. 
    

    Is it necessary to set the ADV7280 to output the start code at the beginning of the frame?
    

     
    

    Thanks and regards,
    

    Takuya

      Hi,
      

        These details we can check with 'MIPI DPHY version 1.00.00 specification' to check whether the output data format is compliance with MIPI-CSI2 Specifications and this is the best way whether whether the output data format is compliance with MIPI-CSI2 Specifications.
      

        Please refer http://www.jmrcubed.com/vr/ref_te/mipi_d_phy_specification_v01-00-00.pdf
      

       
      

      MIPI CSI-2 uses short packets for frame events, and long packets for the image data. Between each packet, the link goes into a low-power state in which it remains until more data needs to be sent.
      

      Note: 
      

      By default the ADV728x-M outputs MIPI frame start/end packets as well as line start/end packets. Further information on this is available in the MIPI CSI-2 specification.
      

      Note that Frame start/end packets are required by the MIPI CSI-2 specification but line start/end packets are optional.
      

      

      Thanks,
      

      Poornima
