Debugging/inspecting code can be done through a debugger tool, or through logging. For this case I think to the easiest and most convenient approach is to just add some logging inside the mentioned functions.

Logging

Add #include <sys/printk.h> at the top of the file (e.g. boot_serial.c) and use printk("This will get logged in a Terminal");. E.g. add printk("Inside boot_serial_start()\n") in boot_serial_start()
- You could also use BOOT_LOG_INF("This will get logged");
Then you should open a serial terminal (open several terminals, since the nRF9160 DK exposes several COM ports) to display the messages, e.g. use Termite with these settings

Debuging options:
