-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear pikao,
you are trying to _run_ that file rather than writing into it to enable a GPIO line. And hence the file doesn't have execute right (as it meant to written into, not execute) you get a permission error. You need to call something like: echo 48 > /sys/class/gpio/export to enable a GPIO line. See for example http://www.armhf.com/using-beaglebone-black-gpios/ for further details.
