CMSIS build problems with IAR Embedded Workbench ver. 6.30.6

If you try to use the STM32 Library examples with IAR 6.30.6 you get a loot of errors.
Below there is the solution.

The customer's file: 
...\Libraries\CMSIS\CM3\CoreSupport\core_cm3.h 
is a very old version of CMSIS (V1.30 from 2009) with no adaptations for IAR Embedded Workbench for ARM.
It is not possible to use this old header file with EWARM 6.30.6.
Included and integrated in IAR Embedded Workbench for ARM 6.30.6 is "core_cm3.h" version V2.11 from 2011.
See the directory: 
<EWARM>\arm\CMSIS\Include\core_cm3.h
To take advantage of this new, improved CMSIS library, just select: 
Project -> Options -> General Options -> Library Configuration -> Use CMSIS

The fix for this project as described by Technical Note 75890:
http://supp.iar.com/Support/?note=75890
is to:
A. Rename the outdated CMSIS file "...\Libraries\CMSIS\CM3\CoreSupport\core_cm3.h" to "core_cm3.h.old" (for example)



B. Enable CMSIS:  Project -> Options -> General Options -> Library Configuration -> Use CMSIS

CMSIS build problems with IAR Embedded Workbench ver. 6.20

If you use IAR release 6.20 and STM Library 3.5 you probably have a lot of errors (see below).

This is caused to the fact that IAR now incorporate CMSIS files that are also inside the STM Library.
This problem is known and the IAR solution is here (html page) or here (pdf).

My solution is: commenting the line 93 in the file core_cm3.c, see below. 



It is not an elegant solution but it work.

Constructing a bootloader with IAR Embedded Workbench and the STM32F207ZG-SK

As software becomes more and more complex, the potential for defects to exist in shipped code increases exponentially. 
It is therefore becoming quite common for design specifications to call for the ability to dynamically update a device’s firmware in the field. 
This is done commonly via a bootloader. In this article, we will discuss some of the issues involved with developing a bootloader and show you how to set one up with the Embedded Workbench on the STM32F207ZG-SK board.
