Re: undefined reference to `app_main'
I noticed that on newer esp-idf versions, the reference to 'app_main' only works when the main folder of the project is named "main". Had it already twice, I think both times with an esp32S3. Lost a lot of time but now I have already changed it in all my projects, even some examples have folder name...
