I have been tried to evaluate BF609's performance with BF609 ezboard and Video decoder extender.
I tried FramCaputure example packaged in Video_Decoder_EI3_Extender_Board-Rel1.0.1.
It seems that BF609 never captures any image when FrameCapture is downloaded and excuted. In addtion to FrameCapture example, all examples packaged in Video_Decoder_EI3_Extender_Board-Rel1.0.1 don't work as well. EPPI0 registers configured after running and stopping BF609 are shown below. Only EPPI0_IMASK was configured. I think that ADI drivers associated with ADV7842 would be wrong.
