Hello
I just built Buster and preempt and linuxcnc on an RPi3B ( not B+)
I could not loadrt hal_pi_gpio.
I got error Unrecognized revision.
I see there is an error in code to identify revision.
The file cpuinfo.c searches for the text "Raspberry" in the file
/proc/cpuinfo.
It doesnt exist for my RPi3B
(the output of cat /proc/cpuinfo is attached )
........
Following as reported in
https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md
I have proposed a commit:
https://github.com/elovalvo/linuxcnc/blob/patch-3/src/hal/drivers/cpuinfo.c
In this commit your revision (a32082) is also included
