Sat 03 Mar 2018 10:10:16 PM UTC, original submission:   When using a Raspberry Pi to program an atmega2560 using linuxgpio and you do not have the permission to access /sys/class/gpio/gpioX/direction it would leave the gpio pin exported.  The only way to unexport the pin would be to reboot the Rasbperry Pi. The problem lies in the function linuxgpio_open, change line 280 from: if (r < 0)    return r; TO: if (r < 0) {    linuxgpio_unexport(pin);    return r; }
