IAR Embedded Workbench for Eclipse (EWARM version 8.x)

Known issues

• Manually specifying MISRA options in the Compiler Extra Options field requires the global MISRA settings to be turned off. (ECL-2929)
• Eclipse Expressions View, Variables View and mouse hover fails to properly display unique_ptr and vectors (ECL-2766)
• TrustZone options are not supported yet. (ECL-2686)
• The MISRA options in the GUI cannot be overridden per-file. The compiler and linker "Extra Options" field can be used to specify MISRA flags per file or folder manually. When this happens, the MISRA options in the GUI need to be turned off, and only the Extra Options should be used. Please refer to the Embedded Workbench Misra C Reference guides for details on the command line option syntax. (ECL-2682)
• The General > Tracing preference page might be missing when installing our plugins in the Eclipse CDT distribution. (ECL-2668)
• Using source file or source folder names containing spaces is not supported by the Gnu Makefile builder and will result a linker error. See http://savannah.gnu.org/bugs/?712 (ECL-2664)
• Parts of the Eclipse help option reference are out of date. Please refer to the Embedded Workbench guides for up to date documentation. (ECL-2655)
• There is no support for TI:s MSP-FET and XDS debug probes. (ECL-2637)
• Excluding / including a source file from the project will cause recompilation of all files because of a known Eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=193286 . Also note that object files for the excluded sources will not be automatically removed from the build output folder. (ECL-2625)
• There is no support the CMSIS-DAP debugger probe. (ECL-2503)
• Certain debugger macros cannot be used without deadlocking the Eclipse UI, for example __messageBoxYesNo. The deadlock can be broken by terminating the CSpyServer2.exe process, although this will terminate the debug session. (ECL-2465)
• The view id of C-SPY views (e.g. "C-SPY Locals") has changed, and these views will no longer work. The workaround is to close these views, and open the corresponding new views from the Window → Show C-SPY View... menu. (ECL-2404)
• Per-file C-RUN settings are not yet supported (ECL-2190)
• The ST-LINK probe selection dialog is not supported in Eclipse. A probe must be selected via its serial number. (ECL-2047)
• Under specific conditions, a breakpoint failing to install in the current debug session might cause the debugger to display an incorrect source file when the target suspends. If this occurs, a workaround is to delete all breakpoints from the Breakpoints view and restart the debug session. (ECL-1947)
• A C-SPY debugger launch will only succeed if the executable is inside of the project being debugged. A workaround is to create a linked resource inside the project pointing to the executable, and enter the project-relative resource path in the Executable field of the launch configuration. (ECL-1816)
• Multi-file compilation is only supported for the entire project. (ECL-1811)
• Using the "@" placement operator in a function declaration will result in a syntax error being reported by the CDT indexer. The workaround is to use a #pragma location instead. (ECL-1801)
• In projects which use many/long include paths, the compiler command line might exceed system limits, which in turn might cause the Eclipse CDT Internal Builder to truncate it. A workaround is to build the project using make, via Project > Properties > C/C++ Build > Tool Chain Editor > Current builder, by setting it to Gnu Make Builder. For further information about Eclipse CDT and command line length, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=72965 . (ECL-1794)
• The Debugger settings tabs do not support Eclipse build variables syntax (e.g. ${ProjName}). However, EW variables are supported ($TOOLKIT_DIR$, etc). (ECL-1650)
• Binaries created via the Output Converter options are not displayed in the project Binaries group. (ECL-1581)
• The Embedded Workbench "Project > Download" submenu is not available in Eclipse yet (download without debug, erase memory). (ECL-1235)
• When the "@" placement operator is used in a declaration, the CDT Indexer will also report a dummy char * @ variable declaration after it. (ECL-1193)
• The CDT Variables view might not display a parent class correctly in some cases. Use the C-SPY Locals view instead. (ECL-740)
• There are several Eclipse issues affecting Parallel Build: post-build actions will not run (see Eclipse bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=408948), a "build error: null" message is displayed at times (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=289048) and under some conditions, building a project might always result in a full rebuild (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=217674). (ECL-164)

• Fixed an issue where the canvas in C-SPY views might get corrupted. (ECL-2715, resolved 2018-06-15)
• Fixed a syntax error in the makefiles generated by the Gnu Makefile Builder which would be detected when running them in Cygwin make.

It is enabled by setting the Eclipse debug option com.iar.ide.common/debug/chrometrace to true in the .options file, or by selecting it in Window → Preferences → General → Tracing → Enable tracing → IAR Toolchain and Debugger Tracing.
