Hi,

I already know the pinout-listing of the BeagleBone Black but this
does not seem to solve my problem. Depending on the choosen
pin-mux-mode the eMMC signals can appear on different pins on P8/P9.
So I need to know the real wiring, means which pins on P8/P9 are
electrically connected to CPU and eMMC. Unfortunately I do not
understand the wiring diagram good enough to find the answer there. So
I hoped there is a pinout-listing available somewere that contains the
information which of the pins are also wired to eMMC...
