What is the significance of the aligment settings? What happens when I leave it at 4? Or at STM32F407 must be 8?
You probably won’t notice any problems with it at four until you use 64 bit numbers, or use a library function that makes assumptions about how 64 bit numbers are stored. The most common symptom is getting an incorrect value for a printf() with a floating point modifier.
