当系统中，只有一个程序时，可以直接从起始地址开始运行；但当系统中有两个程序时，例如带bootloader的系统，则应用程序的运行需要通过bootloader跳转，和bootloader相比，应用程序的地址和中断向量表地址都发生改变，如何告诉编译器来分配bootloader和应用程序在flash中的地址以及如何告诉CPU中断表向表的位置，是本文讨论的主要内容。

在IAR环境下，用寄存器实现STM8S003单片机串口打印函数printf功能。只需要将添加头文件stdio.h并将输出字符函数重定向即可。

该压缩文档主要包括了IAR for stm32_新建工程实例，IAR下用JLINK_调试STM32心得，STM32固件库详解以及STM32编程的一些日记，对于刚刚学习stm32的人来说很不错的哦
