ESP-SR Basic Example does not work

Hi, I am trying to upload the basic example of esp-sr on my esp32-s3 (esp32-s3 DevkitC 1 N16R8), the upload is done correctly but in the serial I see this

(I have the Core Debug Level in Verbose)

I share with you the code although it is the same of the example without modification

I have downloaded the libraries from the github repository, latest version of the esp32 core.

Maybe start with basic sketches to make sure you know how to do an upload, and that the right drivers are installed, etc.

3

Yes, I already done that

4

Have you also checked that the Boards 3 migration isn't an issue?

5

You have a runtime error you need to handle. I don't know the lingo, but you need to provide an exception handler where you can place some debug prints.
