Intel DCI-DbC on Skylake-U

[Benjamin Doron]

Hi all,
Does Skylake-U support DCI over USB3-DbC (standard USB 3.0 debug cable), or
only with the SVT-CCA? I've seen conflicting information on this matter.

In my attempts (using USB3-DbC), Intel System Debugger was able to
successfully identify only the PCH as a "custom" configuration, but just
once (perhaps due to an issue with the host, but now, the "Target
Indicator" indicates an "access error").

Debugging the PCH is not very useful to me, but as far as I can tell, my
board (an Acer Aspire VN7-572G laptop) should be compatible with DCI in
general. I'm not certain what I'm looking to see on the schematics or
boardview, but I think that the CPU and PCH JTAG lines are connected. The
ME also permits CPU debugging (if it's relevant, Boot Guard is disabled).

Thanks for any and all help,
Benjamin Doron
