I found this command: cat /sys/kernel/debug/gpio
GPIOs 0-31, gpio:
gpio-6 (mmc_cd ) in lo
GPIOs 32-63, gpio:
gpio-45 (w1 ) in lo
gpio-52 (eMMC_RSTn ) out lo
gpio-53 (beaglebone:green:usr) out lo
gpio-54 (beaglebone:green:usr) out lo
gpio-55 (beaglebone:green:usr) out hi
gpio-56 (beaglebone:green:usr) out lo
gpio-59 (McASP Clock Enable P) out hi
gpio-60 (sysfs ) in hi
It looks like the appropriate PIN is loading and listening correctly. I'm
at a loss
