Hi,

The hardfault library will print out more info about what that is causing this to fault. You have to enable the hardfault library first by:

Enabling HARDFAULT_HANDLER_ENABLED in sdk_config.h by setting it to 1.
Add hardfault_implementation.c and hardfault_handler_gcc.c from \components\libraries\hardfault to your project.

Do you see a more verbose log being printed now?

Hi,

Can you follow the instructions in this thread to activate the Hardfault handling library. Next, can you rerun the application and see if a more detailed log is printed when the application stops?
