Hello @sunshine88 ,
IVT/DCD support in Configuration Tools depends on the selected device and on the scope implemented in the installed tool package. The fact that the IVT editor is disabled does not mean that the RTD example project is invalid.
For the selected S32K358 configuration, the graphical IVT/DCD editors are not available in Configuration Tools. These tools are related to BootROM/boot-image configuration and are not required for the standard projects.
Therefore, if Update Code and the project build complete successfully, the project can still be used normally for the supported configuration areas such as Pins, Clocks and Peripherals.
Best regards,
Pavel
