Important information

• To be able to see information about the size of the generated object files in the Build message window, you must select message level All under Tools>Options>Messages>Show build messages.

New features

• Find in files improvements
  Regular expressions: You can now use regular expressions in the search field, if the corresponding check-box is selected. The regular expressions must use the Perl standard.

  Search the whole workspace: You can now let the search traverse all projects in the workspace by selecting the option For all projects in workspace. The option will be unavailable if the option Directory is selected.

Known Problems

• EW21123: The Edit>Navigate>Go to definition command in the editor window does not work if the symbol definition is located in a header file that is included in another header file. An example is the msp430.h file that includes all other device-specific header files.
  The workaround is to include the device-specific file directly in your project.

• EW20738: If you select ELF/DWARF as output format from the linker, only the ELF part with symbol information etc will be generated. The DWARF part is not provided which means that it is not possible to use the output file for debugging. The linker does not generate any warning message about this.

• EW20351: The IDE does not remember which monitor was used the last time, it will always start up on the primary monitor.

• EW20146: The automatic indentation does not work in some rare cases.

• EW19886: If you move your Embedded Workbench project, you must not break any paths to source files that have been added to it. Therefore, remember to move all added source files located on the same drive as the project file.

• EW19864: The following code causes the Go to function button to malfunction:
  

  #ifdef SOMETHING
    if (condition_1) {
  #elif
    if (condition_2) {
  #endif
  

• EW17444: When a workspace is created on a computer with a source code control system installed, the SCC information is stored in the workspace file (.eww). This causes problems if the workspace is moved to a computer without SCC.
  The only way to remove the information related to the source code control system is edit the .eww file.

• EW16325: The IDE may crash under WinXP if the user logs out while the IAR Embedded Workbench is running.

• EW16126: If a file is moved between two source groups in the Workspace window using drag and drop, the moved file is not selected after the move operation. Instead a file in the first group becomes selected.

• EW15459: Remarks from the compiler are not displayed in the summary of errors/warnings on compiler level in the message window even if remarks are enabled. However they are counted as warnings on the project level.

• IAR Embedded Workbench IDE - Known problems.

Program Corrections

• EW21588: Multiple blank spaces are no longer removed from instantiated code templates.

• EW21382: If you specify a custom value for the Target VCC option on the Project>Options>FET Debugger>Setup page, it will be saved when you close the dialog box.

• EW20275: Breakpoints with a path that were not under $PROJ_DIR$ were not saved with relative paths. Paths on the same drive are now always saved as relative to $PROJ_DIR$, regardless where the file resides (unless it is actually under $TOOLKIT_DIR$, in which case it will be relative to $TOOLKIT_DIR$).

• IAR Embedded Workbench IDE - Corrected problems.

User guide corrections

The corrections below refer to the PDF versions of the user guide MSP430 IAR Embedded Workbench IDE User Guide, U430-6. The information in the PDF files is, in the event of any differences, more accurate than the printed user guides and the online help files.

• EW21378: Part 7, IAR Embedded Workbench IDE reference, Menus, Embedded Workbench startup dialog box, page 318
  The Embedded Workbench startup dialog box has been replace with IAR Information Center.

Miscellaneous

Nothing.

4.11B 2008-07-10

Program corrections

• EW20128: Modulo operator with divisor 0 within preprocessor directives could cause IAR Embedded Workbench to terminate abnormally. This has been corrected.

• EW19981: When position independent code is selected and switching to a 430X core, position independent code will now be unselected.

• EW19879: The Embedded Workbench IDE could terminate abnormally if the application JAWS from Freedom Scientific was running concurently. This has been corrected.

• EW19805: A preprocessor directive in the form of #define X(y) #x could cause abnormal termination of IAR Embedded Workbench. This has been corrected.

• EW19778: A problem with keeping user-defined key bindings has been corrected.

• EW19736: The option --core=430X will now be inherited when "override inherited settings" are selected in the C/C++ compiler options.

• EW18979: The release built FET examples have been removed.

New features

None.

3.42A 2006-12-07

Program corrections

• EW18318: Under certain circumstances, project member files that were excluded from build could still be considered when computing the build sequence, causing unexpected build errors. This has been corrected.

• EW18187: The Auto Indent function now better handles lines already indented using tabs (previously this could also cause a crash in unusual circumstances).

New features

• New Find commands
  Two new search commands have been added, Find Next (Selected) and Find Previous (Selected). If there is a non-empty selection, that text is immediately searched for. Otherwise, if there is a word surrounding the insertion point, that word is searched for.

• New source browser filter
  A new filter, Non-member functions & variables has been added to the source browser context menu. This filter will limit the display to functions and variables that are not members of a class.
  

3.41A 2006-04-13

Program corrections

• EW17825 The MSP430 device linker configuration files defined the CODE segment before the DATA16_C and other CONST segments.
  The CONST segments (DATA16_C, DATA16_ID and DIFUNCT) are now placed before the CODE segments.
   
• EW17805: There was a typo in the file syntax_asm.cfg, the instruction rra.w was incorrectly defined as rra:w.
