Description: STM32启动过程解析
1、 通过boot引脚设置可以将中断向量表定位于SRAM区，即起始地址为0x2000000，同时复位后PC指针位于0x2000000处；
2、 通过boot引脚设置可以将中断向量表定位于FLASH区，即起始地址为0x8000000，同时复位后PC指针位于0x8000000处；
3、 通过boot引脚设置可以将中断向量表定位于内置Bootloader区，本文不对这种情况做论述；
而Cortex-M3内核规定，起始地址必须存放堆顶指针，而第二个地址则必须存放复位中断入口向量地址，这样在Cortex-M3内核复位后，会自动从 起始地址的下一个32位空间取出复位中断入口向量，跳转执行复位中断服务程序。对比ARM7/ARM9内核，Cortex-M3内核则是固定了中断向量表 的位置而起始地址是可变化的。

Description: KEIL开发STM32F103程序，在片外NorFlash或者是SRAM中运行。
STM32F103有三种启动方式，但是都无法直接在NorFlash或者片外SRAM启动，因此需要BootLoader，然后再执行跳转。
附件里有三个文件夹，一个是BOOT，一个是NorFlash应用程序，一个是SRAM应用程序，都是采用KEIL3.8编译。
本次选用BootLoader放在片内Flash，启动后配置FSMC_SRAM、以及FSMC_NOR，然后执行跳转到片外运行。
-KEIL development STM32F103 program, or SRAM chip NorFlash run. STM32F103 There are three ways to start, but they are not directly or SRAM chip start NorFlash, requiring BootLoader, and then perform a jump. There are three folders in Annex A is BOOT, one is NorFlash application, an application is SRAM, and are based KEIL3.8 compilation. The choice of BootLoader on-chip Flash, after the startup configuration FSMC_SRAM, and FSMC_NOR, then execution jumps to the chip to run.
