在配置之前，先看看这个。Stm32中，存储器映射的图如下：

STM32三种启动模式对应的存储介质均是芯片内置的，它们是：
1）用户闪存 = 芯片内置的Flash。
2）SRAM = 芯片内置的RAM区，就是内存啦。
3）系统存储器 = 芯片内部一块特定的区域，芯片出厂时在这个区域预置了一段Bootloader，就是通常说的ISP程序。这个区域的内容在芯片出厂后没有人能够修改或擦除，即它是一个ROM区。

在每个STM32的芯片上都有两个管脚BOOT0和BOOT1，这两个管脚在芯]]>https://blog.youkuaiyun.com/lbjfeng/article/details/5642631https://blog.youkuaiyun.com/lbjfeng/article/details/5642631lbjfengWed, 02 Jun 2010 16:29:00 +0800AMBA简介
    随着深亚微米工艺技术日益成熟，集成电路芯片的规模越来越大。数字IC从基于时序驱动的设计方法，发展到基于IP复用的设计方法，并在SOC设计中得到了广泛应用。在基于IP复用的SoC设计中，片上总线设计是最关键的问题。为此，业界出现了很多片上总线标准。其中，由ARM公司推出的AMBA片上总线受到了广大IP开发商和SoC系统集成者的青睐，已成为一种流行的工业标准片上结构。AMBA规范主要包括了AHB(Advanced High performance Bus)系统总线和A]]>https://blog.youkuaiyun.com/lbjfeng/article/details/5605279https://blog.youkuaiyun.com/lbjfeng/article/details/5605279lbjfengTue, 18 May 2010 20:05:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5564365https://blog.youkuaiyun.com/lbjfeng/article/details/5564365lbjfengThu, 06 May 2010 19:15:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5408090https://blog.youkuaiyun.com/lbjfeng/article/details/5408090lbjfengTue, 23 Mar 2010 14:10:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5397101https://blog.youkuaiyun.com/lbjfeng/article/details/5397101lbjfengFri, 19 Mar 2010 17:10:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5344779https://blog.youkuaiyun.com/lbjfeng/article/details/5344779lbjfengThu, 04 Mar 2010 10:22:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5316031https://blog.youkuaiyun.com/lbjfeng/article/details/5316031lbjfengMon, 22 Feb 2010 10:12:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5258512https://blog.youkuaiyun.com/lbjfeng/article/details/5258512lbjfengTue, 26 Jan 2010 16:46:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5258221https://blog.youkuaiyun.com/lbjfeng/article/details/5258221lbjfengTue, 26 Jan 2010 15:38:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/5042656https://blog.youkuaiyun.com/lbjfeng/article/details/5042656lbjfengSun, 20 Dec 2009 11:35:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/4943109https://blog.youkuaiyun.com/lbjfeng/article/details/4943109lbjfengFri, 04 Dec 2009 23:31:00 +0800https://blog.youkuaiyun.com/lbjfeng/article/details/4639507https://blog.youkuaiyun.com/lbjfeng/article/details/4639507lbjfengWed, 07 Oct 2009 15:57:00 +0800
