ADV7511/7612 routines not outputting video

My customer has the below two rountines that initialize the 7612 and the 7511. The 7511 comes up and outputs video from a test pattern generator in an FPGA. The 7612 does not operate. I was hoping you provide any clues as to why the ADV7612 does not output video?
