Does the code run if you comment out 'lora_send("coucou", 7);
Does it still crash with simple main() { _delay_ms(1000);
stty_print("hello");}

That is start removing code until it works, when you find the line in main
that causes a crash, go into that function and start removing code until it
works.  Slowly you will find the problem.
