Thanks uilka_b for replying. Yes I agree with you, I did not see the need for the CPS but when I remove it and go directly from the Frame Reader to the CVO it does not work. QSYS is happy

but it does not work. From what I can see, the CPS receives 4 bytes of which only 3 are needed (23:0 = RGB) and the 4th one (31:24) is discarded. I would love to get rid of it, what am I missing? Again, if I go directly from the Frame Reader to the CVO 3 color planes all the way things don't work, I don't get any license warning and no "time limited" .sof. But it does not work. Can someone explain this?

The SD card controller from TERASIC simply uses 3 PIOs and some SW - don't need Altera's IP.

Thanks,

Guys
