Exception handler in zephyr + SPM on nRF9160

[Chris Burns]

According to the Zephyr documentation here the way to implement an application-specific exception handler is to define k_sys_fatal_error_handler. When I try to do this I get a build error with this message:

multiple definition of `k_sys_fatal_error_handler'

and it points me to <my path>\ncs\v1.3.1\nrf\lib\fatal_error\fatal_error.c where it's defined.

Is there a way to define an error handler for my application without having to modify the fatal error handler in NCS?

I should have looked more before asking the question. Adding CONFIG_RESET_ON_FATAL_ERROR=n to my prj.conf file allowed me to define my own error handler.
