IAR怎么把HEAP放到.bss,.data之后？？

发现IAR默认情况下，总是把HEAP放在了.bss,.data的前面，
有没有办法把HEAP放到.bss,.data之后？？

不知道你用的是哪个版本
4.42里面只要更改.xcl文件中各段出现的先后顺序即可

当然是 5.XX

place in RAM_region { readwrite };
place in RAM_region { block HEAP };
place in RAM_region { block CSTACK };

窃以为楼上的方法可行
不过没有东西验证

4楼的方法行不通。

4楼试过吗？还是就我的不行？

//设置部分
define symbol RAM_SIZE = 1024*16;
define symbol ROM_SIZE = 1024*64;

define symbol CSTACK_SIZE =  1024*1;
define symbol HEAP_SIZE =  1024*1;

//非设置部分
define symbol RAM_START  = 0x20000000;
define symbol ROM_START  = 0x08000000;

define symbol INTVEC_START = ROM_START;

define memory mem with size = 4G;

define region ROM_region = mem:[from ROM_START  size  ROM_SIZE];
define region RAM_region = mem:[from RAM_START  size  RAM_SIZE];

define block CSTACK with alignment = 4, size = CSTACK_SIZE  { };
define block HEAP    with alignment = 8, size = HEAP_SIZE { };

initialize by copy { rw };
do not initialize  { section .noinit };

place at address mem:INTVEC_START {ro section .intvec };
place in ROM_region {ro code,ro data};

place at start of  RAM_region {rw};
place in RAM_region {block HEAP};
place at end of RAM_region {block CSTACK};
