What are default values for confgen.py for kconfig?

Loading defaults file ./sdkconfig…

Hello, what branch of my fork are you using? I recommend using the upstream version of the repository based on a release tag. Code in my branches are typically for development or one-off examples and are not tested in the same way the releases are.
