iar error

1.IAR7.5版本软件打开老版本的工程错误

Error[Pe147]: declaration is incompatible with "__nounwind __interwork __softfp unsigned long __get_PSP(void)" (declared at line 52 of "C:\Program Files (x86)\IAR Systems\Embedded  C:\Users\robot.xiong\Desktop\资料\STM32_Update14\STM32_Update\STM32_App\Libraries\CMSIS\inc\core_cm3.h 1084 

解决方法：打开你自己的工程中的CMSIS文件夹，里面有个inc和src文件夹，分别删除里面的core_cm3.h和core_cm3.c ，然后打开工程配置Options for node “XXX”选项->General Options->Library Configuration,值勾选又下脚的Use CMSIS 即可.原因是新版的IAR安装目录中已经有该文件，so不需要STM32库自带的内核文件了。

2.IAR7.5版本软件打开老版本的工程警告

：Warning[25]: Label 'Reset_Handler' is defined pubweak in a section implicitly declared root C:\Users\robot.xiong\Desktop\资料\STM32_Update14\STM32_Update\STM32_App\Libraries\CMSIS\startup\startup_stm32f10x_hd.s 142 

打开.s文件，从Default interrupt handlers.开始，

        ;SECTION .text:CODE:REORDER(1)                   ；屏蔽该行

SECTION .text:CODE:REORDER:NOROOT(1) ；添加该行

改过效果如下：
