Post by charly29160 on CmpCharDevice blocks gpiochip access on Raspberry Pi 5 since update from SP18 to SP21 ^{CODESYS Forge talk (Post)}
Hi, after updating CODESYS Control for Raspberry Pi SL from patch level 18 to 21 (currently 4.21.0.0), the IoDrvGPIO driver ("GPIOs B+/Pi2") can no longer open any GPIO chip on a Raspberry Pi 5. Log output on login: Could not open GPIOChip0. Access to path /dev/gpiochip0 not allowed. Add /dev/gpiochip0 to permitted paths in configuration file if required Could not open GPIOChip4. Trying to open GPIOChip0 Access to path /dev/gpiochip4 not allowed. Add /dev/gpiochip4 to permitted paths in configuration file if required Could not open any GPIOChip. System details: Raspberry Pi 5, 32-bit Raspberry Pi OS (armv7l), kernel 6.12.47+rpt-rpi gpiodetect correctly shows gpiochip0 [pinctrl-rp1] (54 lines) as the RP1 GPIO controller Runtime: CODESYS Control for Raspberry Pi SL 4.21.0.0, Runtime Toolkit SP21+ This worked without issues before the update to SP21. I've tried adding the following to CODESYSControl_User.cfg without success: ini[CmpCharDevice] Linux.DevicePath.1=/dev/gpiochip0 Linux.DevicePath.2=/dev/gpiochip4 Could you tell me the correct section/key to whitelist /dev/gpiochip0 (and /dev/gpiochip4) for CmpCharDevice? I suspect this is part of the general security hardening introduced around SP21 (similar to ForceIecFilePath for SysFile, or the new Gateway "accept local clients only" default), but I couldn't find it documented anywhere. Thanks in advance!

Post by mabac on No file found ^{CODESYS Forge talk (Post)}
CODESYS introduced many cyber security related changes over the last few years, one of them is to restrict file access. By default, file access is restricted to the PlcLogic folder and subfolders of the CODESYS control runtime of version 3.5.19.0 and newer. For Control Win this would be the folder C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxxxxxxx\PlcLogic\ To enable access to other folders, you can configure additional paths by adding them to the file CODESYSControl.cfg. For example: [SysFile] FilePath=C:/temp/test FilePath.1=C:/Users/Public You should now be able to access your file in C:\temp\test\ or in C:\Users\Public
