Support Overview

The following EWARM (Embedded Workbench for ARM) compiler/environment versions are supported:

• IAR EWARM 5.3x.
• IAR EWARM 5.4x.
• IAR EWARM 5.5x.
• IAR EWARM 6.1x (C-only).
• IAR EWARM 6.3x (C-only).
• IAR EWARM 6.6x.
• IAR EWARM 7.4x.
• IAR EWARM 7.8x.
• IAR EWARM 8.11x
• IAR EW ARM 8.20.x (Static Analysis Only)
  

IAR EW integration is provided as follows:

• The preferred method of importing EWARM projects is to use the cpptesttrace utility. See Importing Projects with IAR Embedded Workbench Support for more information.
• C++test also provides a built-in GUI-based EW project importer for EWARM 5.3x-6.3x. The importer is not supported and not recommended for other versions of EWARM.
  • The options extractor works directly with IAR EW project files (.ewp files).
  • The project importer accepts both project (.ewp) and workspace (.eww) files.

The following components are provided to facilitate testing IAR Embedded Workbench projects:

• Compiler configurations for specific supported versions of IAR compiler for ARM (listed above).
• "Use options from IAR Embedded Workbench project" options source.
• "Import IAR Embedded Workbench projects" importer GUI.

• CLI/Batch mode importer: "-ewp" option + "localsettings" properties: "ewp.import.config", "ewp.import.linked", "ewp.import.location", "ewp.import.subdirs", "ewp.import.pathvar.enabled", "ewp.import.pathvar.name", "ewp.import.pathvar.value".

• "IAR_iccarm.mk" Runtime Library build configuration file for building C++test Runtime Library with IAR ARM compiler versions starting from v. 6.1x using 'make'.
• "IAR_iccarm_5_5x_and_older.mk" Runtime Library build configuration file for building C++test Runtime Library with IAR ARM compiler versions 5.3x-5.5x using 'make'.
• Test Configurations prepared for launching Unit & App Testing on C-SPY Simulator:
  • Run IAR EW Tests (Batch Template) - uses EW-generated batch scripts ('.cspy.bat') to launch simulator.
  • Run IAR EW Application with Mem Monitoring (Batch Template) - uses EW-generated batch scripts ('.cspy.bat') to launch simulator.
  • Run IAR ARM Tests - a pure manual simulator configuration.
  • Run IAR ARM Application with Mem Monitoring - a pure manual simulator configuration.

Known Limitations

• Some option descriptions may be missing from project files that originate from old EW versions or were generated by other means. If this occurs when the GUI-based EW project importer is used, C++test will assume that the corresponding compiler/linker options are absent and will rely on tool defaults. This may conflict with EW's approach of providing internal defaults for options with missing descriptions.
• The C++test GUI-based EW project importer does not support the following IAR EW project (.ewp) settings: 
  • General Options>Library Configuration> CMSIS> DSPlibrary setting is ignored (regarding linker options).
    Workaround: Manually append appropriate library in Parasoft> C++test> Build Settings> Linkeroptions
  • The General Options> Target> FPU setting is ignored.
    Workaround: Manually add appropriate --fpu option to Project Properties >Parasoft> C++test> Build Settings> Compiler Options.
  • The Linker> List> Generate linker mapfile setting is ignored.
    Workaround: Manually add the appropriate --map option to Project Properties >Parasoft> C++test> Build Settings> Linker Options. 
  • The .no_neon- designated core names are not provided to the --cpu option for Cortex-Ax cores, regardless of the General Options> Target> FPU setting.
    Workaround: Switch Use options from IAR Embedded Workbench project mode to Specify all options manually in Project Properties> Parasoft> C++test> Build Settings and manually adjust all options. 

• Due to the limitation of the preprocessor included with some IAR ARM compiler versions, C++test will not accept the following code for IAR ARM compiler v. 7.2x and earlier:

  #define MHZ *1000000l 
  #define FREQ (1MHZ)
   
  void foo(long freq);
   
  void bar(void)
  {
         foo(FREQ);
  }

  Workaround: space should be inserted between 1 and MHZ:

  #define FREQ (1 MHZ)
     

• C++test does not support the __nounwind keyword because exceptions are re-thrown after they have been caught. If your program contains __nounwind, add the following macro to compiler options under Project Properties> Parasoft> C++test>  Build settings:

  -DCPPTEST_COLLECT_STACK_TRACE=0
 

• C++test does not correctly reconstruct multibyte characters in C.
