在程序下載起始地址，范圍，RAM的地址，范圍，堆棧的配置有兩種方法。其實本質(zhì)是一樣的。

方法1：在EWARM中利用編譯化境配置，如下圖

方法2：修改stm32f10x_flash.icf文件(其實就是方法1)

define symbol __ICFEDIT_intvec_start__ = 0x08004000;

define symbol __ICFEDIT_SYS_FUNC_start__ = 0x08004200; //functab

define symbol __ICFEDIT_region_ROM_start__ = 0x08004000;

define symbol __ICFEDIT_region_ROM_end__ = 0x0803FFFF; //240K的空間，程序下載到這里面

define symbol __ICFEDIT_region_RAM_start__ = 0x20000000;

define symbol __ICFEDIT_region_RAM_end__ = 0x20001FFF; //8K的ram

define symbol __ICFEDIT_size_cstack__ = 400;

define symbol __ICFEDIT_size_heap__ = 200;

define memory mem with size = 4G;

define region ROM_region = mem:[from __ICFEDIT_region_ROM_start__ to __ICFEDIT_region_ROM_end__];

define region RAM_region = mem:[from __ICFEDIT_region_RAM_start__ to __ICFEDIT_region_RAM_end__];

define block CSTACK with alignment = 8, size = __ICFEDIT_size_cstack__ { };

define block HEAP with alignment = 8, size = __ICFEDIT_size_heap__ { };

initialize by copy { readwrite };

do not initialize { section .noinit };

place at address mem:__ICFEDIT_intvec_start__ { readonly section .intvec };

place at address mem:__ICFEDIT_SYS_FUNC_start__ { readonly section SYS_FUNC };

place in ROM_region { readonly };

place in RAM_region { readwrite,

block CSTACK, block HEAP };

從上面的ICF文件可以看到，中斷向量表的地址是0x08004000。同時用戶自定義了一個固定的起始地址0x08004200，用于存放代碼段SYS_FUN
