Created file 90-gpio-access
Code:
SUBSYSTEM=="bcm2711-gpiomem", GROUP="gpio", MODE="0660" SUBSYSTEM=="gpio", GROUP="gpio", MODE="0660" SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/gpio && chmod -R 770 /sys/class/gpio;\ chown -R root:gpio /sys/devices/virtual/gpio && chmod -R 770 /sys/devices/virtual/gpio;\ chown -R root:gpio /sys$devpath && chmod -R 770 /sys$devpath\ '"
SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\ chown -R root:gpio /sys/devices/platform/soc/.pwm/pwm/pwmchip && chmod -R 770 /sys/devices/platform/soc/.pwm/pwm/pwmchip\
I am assuming this is a udev rule ???
I done the following :
Code:
sudo groupadd gpio
sudo cp 90-gpio-access /usr/lib/udev/rules.d/
sudo chmod +x /usr/lib/udev/rules.d/90-gpio-access
sudo usermod -aG gpio cnc
reboot
I started linuxcnc in terminal with following output :
Code:

I am using GPIO 20 for output and GPIO 5 for input, still nothing.
