    HI Sui,

    Can you get a register dump of the patgen page once you have finished programming? Can you complete the below table so I can work on getting a script with all the settings? 

    PATGEN Output   
       
    Horizontal Resolution 1280
    Vertical  Resolution 720
    Total Vertical Blanking  ?
    Vertical Front Porch ?

    Hi SUI,

    Sorry missed one question, What FC speed are you using 4Gbps or 4.16? I will send you an example how to program the color bar by Tuesday.

    HI Sui,

    The 954 data sheet mentions the reference color bar along with that two patterns which are supported- reference color bar and fixed pattern. The provided color bar is the black and white that we have. Can you use RGB 565? This one would have color. 

    For getting a full screen color (blue), need to change the block size to 3 (for RGB888, it’s the default as well), enable fixed color pattern 0x02[7]=1’b1 and change color 0,1,2 to (0xFF, 0x00, 0x00 for blue)- RGB88 inverts the data thus the sequence is BGR for byte n,n+1 and n+2.
