Based partly on http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RPi3BPreemptRT#buildhalgpio
I am trying to add Raspberry Pi GPIO to LinuxCNC (based on the Machinekit code) The makefile in that Wiki page copies the hal_gpio files into the Makefile in the same place as the hal_bb_gpio, but for some reason the bp_gpio files seem to have been added in to the Hostmot2 objects. I have fixed this, and have hal_gpio compiling, but at runtime I seem to have a permissions problem: halcmd: loadrt hal_gpio Note: Using POSIX realtime HAL_GPIO: can't open /dev/gpiomem: 13 - Permission denied HAL_GPIO: can't open /dev/mem: 13 - Permission denied hal_gpio: rtapi_app_main: Operation not permitted (-1) <stdin>:1: waitpid failed /home/andypugh/linuxcnc-dev/bin/rtapi_app hal_gpio Do I perhaps need to add something to the make-setuid section? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
