Yes, please.

I am interested in this mystery.
I really suspect there are some
incompatible versions in Denali IP.

I sent a question about this to Cadence.
They did not admit it. (But I doubt it.)

By the way, Panasonic have been using Denali
NAND controller IP since 2010.
I refer to "Denali NAND Flash Memory Controller User's Guide"
issued on Nov. 30, 2010.
Unfortunately, I can not share it because it is marked as
"confidential".
