Hi dbdeset;
I have the same design to do. cvi->clipper(900x1080)->scaler(1920x1080)->fb(1920x1080)->cvo(1920x1080).
How can I do to get it working?
thx.

hi, you have to place the fb between the clipper and the scaler like vgs wrote... first try using a testpattern-generator and then develop your system step by step....

Since this is an upscale, I would guess that the scaler is applying quite a lot back-pressure on the clipper which in turns applies back-pressure on your input and overflows it. Maybe you could try putting the frame buffer between the clipper and the scaler?
