I wanted to report that the version of LinuxCNC present at http://buildbot.linuxcnc.org/dists/buster/master-rtpreempt/binary-armhf/
with the Raspberry PI 4 (2gb and 4gb) shows this error message: pi@raspberrypi:~ $ halrun halcmd: loadrt hal_pi_gpio Note: Using POSIX realtime unrecognized Raspberry revision, see /proc/cpuinfo hal_pi_gpio: rtapi_app_main: Invalid argument (-22) <stdin>:1: waitpid failed /usr/bin/rtapi_app hal_pi_gpio <stdin>:1: /usr/bin/rtapi_app exited without becoming ready <stdin>:1: insmod for hal_pi_gpio failed, returned -1 halcmd: Note: Using POSIX realtime Also, the .zip file at https://www.linuxcnc.org/iso/linuxcnc-2.8.0-pi4.zip contains 2 identical files with the name: 1) 2020-09-08-linuxcnc-2.8.0-pi4.img 2) linuxcnc-2.8.0-pi4.img Instead, in this version the hal_pi_gpio module works correctly.
