rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

I'm trying to use a static library that I compiled for the ESP32. Some parts of the library work, but if I add a call into another module of this library the esp32 doesn't even boot up and keeps rebooting with

What steps can I take to figure out what exactly is causing the esp32 not being able to startup?

By default, ESP-IDF does not enable C++ exceptions in the compiler. So if C++ code throws an exception, libstdc++ will immediately call abort(). That's what the stack trace is showing.

In ESP-IDF you can enable C++ exceptions in the project config and recompile the ESP-IDF project (you may need to also recompile your static library with -fexceptions, although it looks like this might already have happened):
https://docs.espressif.com/projects/esp ... exceptions

However, from the stack trace it looks like you might be using Arduino? Arduino IDE doesn't support enabling C++ exceptions.

Hey ! Another Arduino user here. Is there a link we can use to understand how to use ESP-IDF to enable C++ exceptions to keep using Arduino after?

Thanks!
