I think this is just a coincidence. The LCDK came after the hawkboard as
its replacement, and I guess there was some effort to derive out of
hawkboard design. But they are not 100% software compatible, like you
are discovering now.

Yes.

Not sure what you mean by "live with inconsistencies on the lcdk". The
two boards need to be treated as close cousins, but independent boards.
