Additionally, using: $ sudo config-pin overlay univ-all $ sudo config-pin P9.15 hi / low
Seems to work fine on the BBG too. However the idea is to use P9.15 as normal through sysfs. Without having to mux the pins. If at all possible. But since pin is not exactly brought out to the header( except that it's tied to gpio1_16 ) it's not going to have a header pin value. However knowing the gpio number needing to be echoed into the export file would be fine too. It such a critter existed. Which I am thinking it is also possible that it also does not exist . . .
