I’m trying to compile [yanjos-dev] amazon-freertos-examples form github and I’m getting the below error. It seems to be needing some default values, but I don’t know how to correct this.

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.
