    Hi together,

    -> I updated my raspberry pi3 with runtime 4.22.0.0, and then no I2C device is running.
    -> when i switch back to runtime 4.20.0.0 all I2C devices running.

    what have i additionally to do, so that I2C Bus is although running in the newest Runtime Version 4.22.0.0 ?

    I did read something about security changes on the new runtime Version, but i do not clear
    understand, what i have do do, do bring the I2C Bus to live again ?

    ... there should be a Dialog in the Runtime Deploy tool, (see the link below) , but im my
    Codesys Version 3.5.22.40 i could not find this "Change Service User button" ...

    strange things happen, so what to do, any Ideas appreciated !

    CODESYSControl_User.cfg
    [CmpCharDevice]
    PermittedPath.0=/dev/i2c
    PermittedPath.1=/dev/spidev
    PermittedPath.2=/sys/class/gpio/
    PermittedPath.3=/dev/gpiochipPerm
    will be solved to 4.23.0.0 release
