I'm supporting one of my customers and we're having difficulty getting S/PDIF to work on his EZ-KIT. I think it may be due to different versions of the EZ-KIT. How do I tell what the revision number for this EZ-KIT is? I see the following information on the board:
A sticker with "1.6" on the top surface of the board on an IC.
A sticker with BOM REV "1.7" on the bottom edge of the board
And "ADSP-21489 EZ-BOARD 0.1" silk screen on the bottom of the board
Which of these items should we compare to tell if our EZ-KITs are same or different?
