在IAR中，硬件环境为STM32F464单片机，额外的CCM不能用DMA访问，但可以作为内部额外扩充RAM使用
修改文件中的内容为：
define symbol __ICFEDIT_region_ROM_start__ = 0x08000000; define symbol __ICFEDIT_region_ROM_end__ = 0x080FFFFF; define symbol __ICFEDIT_region_RAM_start__ = 0x20000000; define symbol __ICFEDIT_region_RAM_end__ = 0x2001FFFF; define symbol __ICFEDIT_region_CCMRAM_start__ = 0x10000000; define symbol __ICFEDIT_region_CCMRAM_end__ = 0x1000FFFF; /*-Sizes-*/ define symbol __ICFEDIT_size_cstack__ = 0x400; define symbol __ICFEDIT_size_heap__ = 0x800; /**** End of ICF editor section. ###ICF###*/ 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 region CCMRAM_region = mem:[from __ICFEDIT_region_CCMRAM_start__ to __ICFEDIT_region_CCMRAM_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 in ROM_region { readonly }; place in CCMRAM_region { readwrite }; //内存分配CCM优先（除堆栈） place in RAM_region { block CSTACK, block HEAP }; //堆区和栈区设置在SRAM
要具设置某个文件生成在CCM区，place in CCMRAM_region { readwrite };修改为：
place in CCMRAM_region {readwrite object tasks.o,
readwrite object heap_4.o };
或者具体到内存中分配的类型（具体查看生成的map文件）修改为：
place in CCMRAM_region {section .bss object tasks.o,
section .bss object heap_4.o };
内存灵活配置，当然也可配置为（注意CCM区不能使用DMA）：
place in CCMRAM_region { block CSTACK, block HEAP }; //堆区和栈区设置在CCM
place in RAM_region { readwrite }; ///内存分配CCM优先（除堆栈）
