DM355 Image Flipping

Gerardo Artola Pola

Hi all,

I'm using the ipipe to flip an image. At the moment, I can do both horizontal and vertical flips, but I have a problem with the chroma. It looks like Cb and Cr bytes are swapped.

I've tried with the CRV bit in the RSZ_SEQ register but this doesn't work.

Can anybody help me with this issue?

Thanks.

Best Regards.

Have you tried CCDCFG.BSWD register field?

That bit (CCDCFG.BSWD) does not help.

It seems like a hardware error. In vertical flipping (RSZ_SEQ.VRV) everything works ok, but in horizontal flipping (RSZ_SEQ.HRV) does not, and Cb/Cr are swaped after processing.

There is a bit in the VPBE (MODE.CS) that swaps the chroma order. But I'm not using any display and I can not find something similar in the VPFE.
