I was trying to use connectors J6 or J7 to connect to the digital microphone inputs on the ADAU1787 eval board. After having no success, I eventually connected the microphone to J5 which worked for me. Taking a closer look at the schematic I now wonder if J6 and J7 are not functional. They connect to nets named "DMIC_0_1" and "DMIC_CLK0" which I do not see anywhere else in the design, elsewhere the nets are named "DMIC_0_1/MP9" and "DMIC_CLK0/MP7", and I cannot ohm out the J6/J7 pins anywhere on the board.

Has ADI tested that the J6/J7 connectors of the ADAU1787 eval kit work? If so, what do I need to do to use them?
