idk, in the out of box default configuration, all valid pin's are pre-exported.. Including 47 debian@bbb-pwr03-ser11:/sys/class/gpio$ ls export gpio117 gpio26 gpio37 gpio5 gpio68 gpio77 gpio9 gpio10 gpio12 gpio27 gpio38 gpio50 gpio69 gpio78 gpiochip0 gpio11 gpio13 gpio3 gpio39 gpio51 gpio7 gpio79 gpiochip32 gpio110 gpio14 gpio30 gpio4 gpio60 gpio70 gpio8 gpiochip64 gpio111 gpio15 gpio31 gpio44 gpio61 gpio71 gpio80 gpiochip96 gpio112 gpio19 gpio32 gpio45 gpio62 gpio72 gpio81 unexport gpio113 gpio2 gpio33 gpio46 gpio63 gpio73 gpio86 gpio114 gpio20 gpio34 gpio47 gpio65 gpio74 gpio87 gpio115 gpio22 gpio35 gpio48 gpio66 gpio75 gpio88 gpio116 gpio23 gpio36 gpio49 gpio67 gpio76 gpio89 debian@bbb-pwr03-ser11:/sys/class/gpio$ uname -r 4.19.94-ti-r43 i'm wondering what blocking that auto export?
