Did you ever get an answer to this? I just bought the EVKB (assuming it is a replacement for EVK); but it seems most of the documentation is still EVK-based. Is there a list of differences anywhere or is there EVKB-based documentation?
We ended up abandoning the EVK and focusing on the EVKB. Spent lots of time staring at the schematics (they jammed *way* too much onto one board). Good luck!
