It looks like the SPI1 lines have been re-purposed as HDMI audio on the BB Black. I was wondering if I can still use SPI1 as SPI and have HDMI still work video only? Would I have to cut the traces to the HDMI part?
Thanks,
Jim
Video and audio are separate functions. No you don’t have to cut any traces on the board. Just make them be whatever it is you want them to be. As stated in the SRM, these are all inputs to the HDMI chip. The HDMI chip will not interfere with the operation of the signals.
