IAR STM32F10x_StdPeriph_Driver 3.4转3.6.1库

1、Fatal Error[Pe1696]: cannot open source file core_cmInstr.h

STM32F10x_StdPeriph_Driver 3.4库移植换成3.6.1库时 出现  Fatal Error[Pe1696]: cannot open source file "core_cmInstr.h"3.6.1库取消了 core_cm3.c 文件 ，增加了 core_cmFunc.h  core_cmInstr.h 文件，只要将这两个文件添加进来即可。

2、Warning[25]: Label ‘Reset_Handler’ is defined pubweak in a section implicitly declared root

IAR编译STM32的M3，早期的版本，需要使用core_cm3文件，6版后就不使用它了。在使用6版的编译成功的项目，现在使用7.1编译，就会出警告，它来自：startup_stm32f10x_hd.s文件内容：Warning[25]: Label 'Reset_Handler' is defined pubweak in a section implicitly declared root等信息如果将startup_stm32f10x_hd.s在项目中去掉，编译将没有任何警告及错误这是可以省去startup_stm32f10x_hd.s文件的节奏？

解决办法

After upgrading to EWARM 7.10.1 the Warning[25] is issued during assembly of a file that assembled without warning on earlier version of EWARM.The assembler (iasmarm) is (from EWARM 7.10.1) issuing Warning[25] for a deprecated assembler construction.The deprecated assembler source construction looks like this:        PUBWEAK NMI_Handler        SECTION .text:CODE:REORDER(1)NMI_Handler        B NMI_Handler

To avoid the warning, add ":NOROOT" to the "SECTION" statement:        PUBWEAK NMI_Handler        SECTION .text:CODE:REORDER:NOROOT(1)NMI_Handler        B NMI_Handler
