I am install linuxcnc 2.9.2 on raspberry pi5 and I am completing all setting for Linux cnc lathe then I started linuxcnc and I found error and error picture I am also attached please see and guide me how to solve this problem
At the moment (2023-07-16) this driver only seems to work on Raspbian as the generic Debian image does not set up the correct interfaces in /dev/gpiomem and restricts access to the /sys/mem interface.
HAL_PI_GPIO: can't open /dev/gpiomem: 2 - No such file or directory
If the error is 'permission denied' then try adding the user who runs
LinuxCNC to the gpio group: sudo gpasswd -a username gpio
HAL_PI_GPIO: can't open /dev/mem: 13 - Permission denied
hal_pi_gpio: rtapi_app_main: Operation not permitted (-1)
try
Code:
sudo gpasswd -a username gpio
where username should be PI or whatever user name you are using.
