How can I execute a custom app for NuttX with minicom?

Question

I wrote my first application for NuttX. I want it to read the state of a button and if its pressed the LED should light up for 1 second. I am using a self created board from a company with a STM32F103 on it. I can activate the app via menuconfig. Then I compile the code and flash the Firmware on the board. I thought if I now open minicom I should be able to execute the app but it isnt possible. What did I do wrong? Also I dont think all of my code is correct. I would appreciate if you could help me there also :)

All my files are:

Make.defs

include $(wildcard $(APPDIR)/BeispielApp/*/Make.defs)

Makefile

MENUDESC = "Beispiel App"

include $(APPDIR)/Directory.mk

BeispielLED.c
