I am using SDK 14.2 and just upgraded to IAR EWARM 8.22.1. When compiling, it now gives me the following complain for virtually every .c file in my project:
Warning: The header file 'cmsis_iar.h' is obsolete and should not be used.
A sutiable version is automatically included from the CMSIS-core package.
This file will be removed in a future release.
I tracked down the include statement to this file: components\toolchain\CMSIS\Include\core_cmSimd.h
I'm not sure if this is something with my IAR installation or with the SDK.
