这家伙很懒，什么也没写！

之前加过一个自定义的 `.version` 段，好像也没出问题

```
/*###ICF### Section handled by ICF editor, don't touch! ****/
/*-Editor annotation file-*/
/* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_0.xml" */
/*-Specials-*/
define symbol __ICFEDIT_intvec_start__ = 0x08000000;
/* 软件及硬件版本号存放地址 */
define symbol __ICFEDIT_version_start__ = __ICFEDIT_intvec_start__ + 512;
/*-Memory Regions-*/
define symbol __ICFEDIT_region_ROM_start__ = __ICFEDIT_intvec_start__;
define symbol __ICFEDIT_region_ROM_end__   = 0x080FFFFF;
define symbol __ICFEDIT_region_RAM_start__ = 0x20000000;
define symbol __ICFEDIT_region_RAM_end__   = 0x2001FFFF;
/*-Sizes-*/
define symbol __ICFEDIT_size_cstack__ = 0x2000;
define symbol __ICFEDIT_size_heap__   = 0x2000;
/**** End of ICF editor section. ###ICF###*/

define symbol __region_RAM1_start__ = 0x10000000;
define symbol __region_RAM1_end__   = 0x1000FFFF;

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 RAM1_region  = mem:[from __region_RAM1_start__   to __region_RAM1_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 RAM_region   { block CSTACK, last block HEAP, section .sram};
place in RAM1_region  { readwrite };

/* armink add for version storage */
keep { section .version };
place at address mem:__ICFEDIT_version_start__ { readonly section .version };

/* armink add for finsh */
keep { section FSymTab };
keep { section VSymTab };
keep { section .rti_fn* };
```

  增加了一个绝对section.导致的。有没有解决办法呢。这绝对地址是一定要的
