Hallo Herr Schwellinger - Danke für die Info. Der Fehler besteht weiterhin: Follow-up: Rootless mode is not the cause here — verified with ps aux, the runtime binary runs as root: root 1974 48.9 0.7 854852 62140 ? SLl 13:00 0:04 /opt/codesys/bin/codesyscontrol.bin /etc/codesyscontrol/CODESYSControl.cfg gpioinfo gpiochip0 as root also works flawlessly (all 54 lines listed correctly, no permission errors at the kernel level). So the block is happening purely inside CmpCharDevice's own sandboxing, not at the Linux/kernel permission level and not due to a dedicated unprivileged user. The correct config key to whitelist /dev/gpiochip0 for CmpCharDevice is still what I'm looking for. Im Voraus herzlichen Dank für Ihre Hilfe Karl Schuler
