i wanted to program the GPIO froml Linux.
so as it was given in this link.
i tried some of these commands mentioned to enable the GPIO control using sysfs.
root@clanton:~# echo -n "27" > /sys/class/gpio/export
but it is not working.
the response is like:
echo : write error : Device or resource is busy
what am i missing.
Help please i am stuck here.
i am using intel galileo
and i am booting the linux from the SD card
The “write error: Device or resource busy”, appears when you attempt to export a GPIO that is already exported. Some GPIOs are already exported by default. Continue writing all necessary commands and try your application.
