I tried to insert a dummy block after chroma resampler. It masks the upper 8 bits with zeros.
But when I connected the FMC camera with zed board I am getting video but with a green display.
My aim is to get a grey image. i was told that in YCRCB 422 if i take y then I get grey image ...But why am I getting green content too?

this is because the chroma chanels are zero-referenced at 128 on a 8 bit/channel system, If you set to 0 you are removing both the blue and red content from the signal leaving only green. Try setting to 128 and you should get greyscale.
