This is my first experiment with bringing some of the A64 gpio mux lines to the outside via the SD card slot; SDIO. These are data lines D0-D3, CMD, CLK, VDD, & VSS. The lines are gpio160 - gpio166; PF0 - PF6.
The pic above is the 48cm ribbon cable that extends the SD micro slot to a full size card adapter; this ribbon is useful in itself; but I plan to modify it for pin access on a solderable bread-board.
These two shots are the modified ribbon cable; this was actually easier than I expected. The cable will extend under the notebook.
The two shots above show the finished cable running; I have the green and red LED(s) initially connected to CMD and CLK. These are pulsing at regular 3/4 second intervals (or so). The gpio(s) are not useful in this state; next I need to hack the dts and make sure that the pin function register has '0' s.
