  1. Hello, No access to GPIO without root. It is necessary for Moonraker. in group grep gpio /etc/group gpio:x:1001:isp isp@3dprinter:~$ echo 10 /sys/class/gpio/export 10 /sys/class/gpio/export but isp@3dprinter:~$ ls -lL /sys/class/gpio/ total 0 -rwxrwx--- 1 root gpio 4096 сен 25 23:10 export drwxr-xr-x 3 root root 0 сен 25 23:10 gpiochip0 drwxr-xr-x 3 root root 0 сен 25 23:10 gpiochip352 -rwxrwx--- 1 root gpio 4096 сен 25 23:10 unexport and isp@3dprinter:~$ sudo cat /sys/kernel/debug/gpio gpiochip0: GPIOs 0-223, parent: platform/1c20800.pinctrl, 1c20800.pinctrl: gpio-17 ( |orangepi:red:status ) out lo gpio-20 ( |reg_vcc_wifi ) out hi gpio-166 ( |cd ) in lo ACTIVE LOW gpio-204 ( |usb0_id_det ) in hi IRQ gpiochip1: GPIOs 352-383, parent: platform/1f02c00.pinctrl, 1f02c00.pinctrl: gpio-358 ( |vdd-cpux ) out lo gpio-359 ( |reset ) out hi ACTIVE LOW gpio-362 ( |orangepi:green:pwr ) out hi if i make echo 10 | sudo tee /sys/class/gpio/export then all ok isp@3dprinter:~$ sudo cat /sys/kernel/debug/gpio gpiochip0: GPIOs 0-223, parent: platform/1c20800.pinctrl, 1c20800.pinctrl: gpio-10 ( |sysfs ) in lo gpio-17 ( |orangepi:red:status ) out lo gpio-20 ( |reg_vcc_wifi ) out hi gpio-166 ( |cd ) in lo ACTIVE LOW gpio-204 ( |usb0_id_det ) in hi IRQ gpiochip1: GPIOs 352-383, parent: platform/1f02c00.pinctrl, 1f02c00.pinctrl: gpio-358 ( |vdd-cpux ) out lo gpio-359 ( |reset ) out hi ACTIVE LOW gpio-362 ( |orangepi:green:pwr ) out hi rc.local: chown -R root:gpio /sys/class/gpio chmod -R 770 /sys/class/gpio 99-gpio.rules SUBSYSTEM=="gpio", PROGRAM="/bin/sh -c 'chown -R root:gpio /sys/class/gpio && chmod -R 770 /sys/class/gpio'" SUBSYSTEM=="gpio", PROGRAM="/bin/sh -c 'chown -R root:gpio /sys/devices/platform/soc/1c20800.pinctrl/gpiochip0/gpio && chmod -R 770 /sys/devices/platform/soc/1c20800.pinctrl/gpiochip0/gpio'" What am I doing wrong? I need to access GPIO without root to work with Moonraker. Thanks!
