It's been a while since I've gotten down and dirty with microcontrollers, but I remember many a long hour debugging errors with terrible logs and information, because it wasn't trivial to determine what the microcontroller was actually doing. Fortunately it looks like with ARM microcontrollers, you can run some additional C code with the help of a built in feature. Amine El Messaoudi's article introduces this feature, and demonstrates how you can get it running.
