Hi Kelvin,
the second option in the wizard (new configuration based on existing project) should be used if you project already contains source files with YAML configuration, such as pin_mux.c or clock_config.c. Almost all SDK examples contain these files and you can open the configuration of the project and modify and then update a source code.
In case you have an empty project or new project created in IAR, that does not contain any of these files, simply create new configuration using third option (new configuration for the processor). We recommend to save configuration file into root folder of your project and then hit "Update Code" button to generate code into the project.
