Category: Installing LinuxCNC
Hi,
I'm a bit desperate. I want to replace my very old pc based linuxcnc with the actual version running on a raspberry pi 5.
I've been trying to get signals to the pin header for a day now.
First of all: Is there a tutorial for raspberry configuration? I found nothing except the general docu and then went from one error message to another.
What I did is:
1. Started Stepconf wizard
2. Replaced parallel port Pins with hal_gpioxxx, see attached hal file
When I start this Setup following error occurs:
This was my try to set the PINs:
halcmd: loadrt hal_gpio inputs=PIN3,PIN5,PIN7 outputs=PIN5,PIN6,PIN9,PIN10,PIN11,PIN17,PIN22,PIN27
Note: Using POSIX realtime
The GPIO line PIN3 can not be found
hal_gpio: rtapi_app_main: Operation not permitted (-1)
<stdin>:12: waitpid failed /usr/bin/rtapi_app hal_gpio
<stdin>:12: /usr/bin/rtapi_app exited without becoming ready
<stdin>:12: insmod for hal_gpio failed, returned -1
halcmd: Note: Using POSIX realtime
Would be nice if onyone could show my where I'm wrong.
Andy
