文章简介:	IROM中可以分成两个区域，起始代码运行地址为0x08000000,这是基本固定的，可以将IROM的0x08000000 ~ 0x08002000这8KB的空间存放Bootloader代码，而0x08002000 ~ 上限的位置存放APP代码。

　　1.STM32 Bootloader与APP

　　IROM中可以分成两个区域，起始代码运行地址为0x08000000,这是基本固定的，可以将IROM的0x08000000 ~ 0x08002000这8KB的空间存放Bootloader代码，而0x08002000 ~ 上限的位置存放APP代码。

　　需要实现两个工程，分别为bootloader工程与app工程。

　　1.1 先说bootloader工程，以IAR为例

　　建立基本stm32工程需要的工程文件等，工程的建立这里不去说明，有了工程后，需要将该工程代码的链接地址配置为0x08000000 ~ 0x08002000，对于IAR可以在icf文件中进行修改参数达到效果，也可在工程配置中修改达到效果，中断向量表的地址为程序运行起始地址就行。

　　1.1.1 在icf中修改链接地址，__ICFEDIT_intvec_start__是中断向量表位置，按照上面说的bootloader地址范围，这里要填起始地址0x08000000，__ICFEDIT_region_ROM_start和__ICFEDIT_region_ROM_end__是配置这部分bootloader代码在IROM中的位置，根据上面说的划分区域，这里start应是0x08000000、end应是0x08002000，后面的RAM_Start与RAM_end是内存的起始地址与结束地址，IROM和RAM的范围应该能根据实际芯片手册去划分修改。修改后到时编译好程序，链接脚本就会将程序链接到对应IROM中。

　　直接通过icf文件修改，其实就是一个链接脚本

　　直接通过工程修改，Vector Table是设置向量表的位置

　　1.1.2 之后就可以开始撸起bootloader代码了，看你的需求是什么，普遍bootloader的需求都是起到一个搬运工的作用，当发现有app的升级文件需要升级时，从一个存放的介质中搬运到IROM中对应的APP代码位置，然后跳转到APP代码位置进行运行。

　　说明：主要就是判断介质中是否有升级文件需要升级，如果有则擦除IROM中APP代码对应的位置，然后将介质中的APP升级文件搬运到IROM中的APP位置去，没问题后，定义一个函数指针指向APP应用程序代码段的地址，就是链接地址0x08002000，然后调用函数指针直接到这个代码段运行，运行之前设置一下APP链接地址数的堆栈。栈顶设置为起始地址的前4个字节，函数指针指向的其实是这个起始地址的后4个字节，表示中断向量表的复位中断向量位置。所以起始地址+4，然后运行。

　　1.2 APP工程，APP的工程搭建好后，同样的要修改链接位置，将程序代码链接到指定的位置去，同样的可以通过icf文件修改，也可以直接通过工程修改，这里就不在进行说明，IROM链接的起始地址为0x08002000，上限就是IROM的上限即可。配置好链接地址后，就可以撸起你的代码了，但如果想要让bootloader跳转到app能够成功，则必须在app代码的开始设置好中断向量的表偏移，因为app的代码是在0x08002000开始，所以中断向量表的位置设置为0x08002000即可。

1 /* 设置中断向量表位置 0x08002000 */
2 NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x2000);

复制代码

　　　如此就完成了bootloader与app工程。一般bootloader写好后是不需要重复的更改的，而只会该应用程序，可以将bootloader代码编译成bin文件，因为bin文件全都是数据，所以可以转换成一个数组，表示一个代码段，然后将这个数据放入到APP的工程中，将这个bootloader的数组指定到一个IROM的位置，这样就可以达到一次烧写两个工程的效果。

　　如何将bootloader的数组指定到固定的IROM中，使用#pragma loation = 0Xxxxxxxxx __root 就可以指定，我是这么指定的，指定到了0x08000000位置。同时APP的工程链接地址要为0x08002000，因为按照上面说的对IROM的划分，应该要如此划分。

#pragma location = 0x08000000

文章简介:	IROM中可以分成两个区域，起始代码运行地址为0x08000000,这是基本固定的，可以将IROM的0x08000000 ~ 0x08002000这8KB的空间存放Bootloader代码，而0x08002000 ~ 上限的位置存放APP代码。
