all_in_one example in crash loop immediately after download #2

Closed haverdude closed 3 years ago

haverdude commented 3 years ago

This issue is in reference to the "all_in_one" example - I have not tried any of the others.

The code is compiling, I have the ESP32S2 branch installed (manually) in the Arduino IDE, I can build and download the code, but all it does is what is shown in the log below.

Is there any particular setup option and / or partition scheme I have to use to make this work?

I had the same exception and it was caused by the MSC example component trying to use the psram of the wrover module without me first enabling it at compile time. Just enable PSRAM in the Tools menu.
