Also, when I try to export a gpio in sysfs echo 9 > /sys/class/gpio/export
It gives me an error in dmesg gpio_request: gpio-9 (sysfs) status -22 export_store: status -22 Here is a look of sysfs on my machine # ls /sys/class/gpio/ -la drwxr-xr-x 4 root root 0 Jan 1 00:00 . drwxr-xr-x 24 root root 0 Jan 1 00:00 .. --w------- 1 root root 4096 Jan 1 00:10 export drwxr-xr-x 3 root root 0 Jan 1 00:00 gpiochip192 drwxr-xr-x 3 root root 0 Jan 1 00:00 gpiochip224 --w------- 1 root root 4096 Jan 1 00:00 unexport
