RPI4 Raspbian 64 bit & LinuxCNC

Sorry about that, I seem to be at war with the forum software. Tried a few times to attach something, kept saying no file attached.
Here we go again.
 

Not my day...

Can you share your ini file?
Further to What Dewey has said the log indicates some missing ini file sections.

  I never made it to a complete .ini file, but I tested many settings (the I86 system that died had an earlier LinuxCNC version. and it got 'converted'. I started from scratch and it took some time to understand the hal file requirements, which I documented first. It was my intention to post one complete working configuration, but after many hours I did not make it that far.

I Attached is the linuxcnc.report I ran just now on the RPI as well as my .hal and .ini file.

Meanwhile, there are a number of problems in the .hal file.
In fact, in the instructions hal_pi_gpio.pin-xx-out and hal_pi_gpio.pin-xx-in the parameter xx refers to the physical pin number of the Raspberry and not to the gpio number.
Furthermore, there is no variant -not used for the estop signal In some lines the command hal_pi_gpio.pin-xx-out (xhome and following) is misspelled.

Attached is the correct version of the commands for the .hal file.
 

elovalvo,

Thanks a lot for clarifying and fixing the gpio assignments.

I am trying to debug at the command line why LinuxCNC does not want to start. I found that when in [EMCMOT] the COMM_TIMEOUT is set to 10 (5 is too short) the following errors disappear:
USRMOT:ERROR: command timeout
emcMotionInit:emcTrayInit failed.

RTAPI then tries to load milltask. However, it fails to find milltask.so in linuxcnc/modules, upon which waitpid times out.

This is with the Linux Raspberry 5.10.74 rt54-V8+ #1 SMP PREEMPT_RT Fri Oct 22 10:15:42 PDT 2021 aarch64 GNU Linux version
LinuxCNC 2.8.2 . The hardware is a RPi 4B 8 GB
