在 IAR 中:在安装目录 IAR Systems\Embedded Workbench\arm\config\linker\ArteryTek 下找到相应 MCU型号的分散加载描述文件*.ICF,复制到 project 路径下,按下图方式启用*.icf 文件。
如果是要放在 Flash 零等待区指定地址,根据需要在零等待区分配一段 region,增加下面红色字体的部分,即可将 my_code.c 内的代码都放入该零等待区内(ZWROM_CODE_region):

如果有多个.c 文件需要放入零等待区,place in ZWROM_CODE_region 可以如下书写:
/* Place Code in ZWROM CODE */
place in ZWROM_CODE_region {ro object my_code1.o, ro object my_code2.o, ro object

如果是要放在 SRAM 指定地址,以 SRAM 扩大到 224KB 为例,根据需要在零等待区分配一段 region,增加下面红色框线内的部方式分,即可将 my_code.c 内的代码都放入该零等待区内(RAM_CODE_region)
