To who may help:
I am a beginer with stm32. Today, I have some promble with my board(stm32f407xx): the main fuction will automatically cycle three times. codes are follow:
/* this function just do some init work for uart1 */
/* printf already redirect to UART1 */
the result from Serial debugging assistant:
My friend told me I should add while(1) at the end of code. But I have write some test code without while(1) before, and it work well. It is really puzzled me. Why?Why?Why? By the way, I use Keil MDK5 to build my code. hope someone can help me.
