Can I use pins muxed to different modes on the same header using a device tree overlay?

E.g., could I take my Beaglebone Black's P9 header and mux pins 28-31 to mode 3 for SPI, and pins 11-16 to mode 7 for GPIO? Or is it the case that must the entire P9 header be used in a single mode?

  • \$\begingroup\$ I'm just getting started on my first Beaglebone design, and it sounds like you've got further than me in working out these details --- I don't really know enough to develop this into a full answer, but it sounds like you might be able to. \$\endgroup\$

The answer is yes you can use pins in whatever modes you want, as long as they don't interfere with on another.
