Designing video system

Hi everyone!

I'm using cyclone 3 and daughter board with tfp410 chip from TI on it.

I need to connect "Clockod Video output" with "SG-DMA" in SOPC Bilder to be able output image to LCD screen from memory. But there is some problem I can't recognize in my design because i can't get anything on my screen.

could anybody give a sample project using "Clockod Video output" and sgdma, please? Or write any suggestions.

    Haven't anybody ever designed video systems using SOPC builder? Please, just give me advice where is my error and what I must do to make that design work. You can request additional information if you need.

    Have you considered using the VIP Frame Reader instead of SGDMA to read the image from memory? If I recall correctly, the Frame Reader was added in Quartus II 9.0.
