for IAR Embedded Workbench for MSP430 version 6.50.1

Read about the latest features, new device support, and program corrections in the release notes.

Highlights

Extended functionality in C-STAT
The static analysis tool C-STAT has been extended with approximately 150 new checks including 90 new MISRA C:2012 checks and two new packages of checks. There are also new options to enable or disable the false-positives elimination phase of the analysis and to exclude files from the analysis. C-STAT message suppression can now be controlled by directives placed in comments in the source files. For more information see the release notes for the compiler.
Extended inline assembler
The inline assembler has been extended with the possibility to take input arguments, have return values, and read or write to C symbols. The syntax is similar to the syntax used in GNU GCC. For more information see the release notes for the compiler.
Support for new devices
Support has been added for the following new MSP430 devices:
MSP430FR2110, MSP430FR2111
Updated user guides
The IAR C/C++ Compiler User, the C-SPY Debugging Guide, and the IAR Assembler Reference Guide have been updated.

Important information

Upgrade information

Before you install

To avoid any problems, do not install this release in a directory where you have previously installed any older version of IAR Embedded Workbench. It is recommended that you either uninstall an earlier product, or install this release in a separate directory. As before, however, it is possible to install different products, all using the same version of the main application, in the same root directory.
License renewal

The upgrade to this version might require a license renewal. This is performed by starting the IAR License Manager and selecting License>Check for License Renewal.
Note, if you have a network license, this must be performed on the license server.

Microsoft Windows

Windows Vista and newer operating systems have a security mechanism called UAC (User Access Control). Disabling UAC will automatically grant you permission when a task requires administrative rights but this is not recommended because it will reduce the security of the computer. It is not necessary to run the IAR Embedded Workbench IDE as an administrator. However, if you are not, modifications to the installed product tree in C:\Program Files\IAR Systems might not work as intended and could give unexpected results. One example is opening and building projects directly from the installed product tree. The build will succeed, but the resulting files (object, list, ...) will not appear where expected. Instead all output files will be redirected by the OS to C:\Users\\AppData\Local\VirtualStore\Program Files\IAR Systems. To avoid this, the preferred way is to copy the examples to a location outside Program Files, either manually or automatically by opening them via the IAR Information Center.
Migration
Project files generated by version 3.x or newer of IAR Embedded Workbench for MSP430 can be opened by the project manager in this version of the product. Project files generated by version 1.x and 2.x can also be opened but the debugger settings will however be lost and must be set again.

If you are migrating from version 2.x or later to this version we recommend that you take a look at the IAR Embedded Workbench for MSP430 Migration Guide for detailed information.

If you are migrating from version 1.x to this version, you can use the Step by step migration for descriptions on how to convert your old projects.
Upgrade from Kickstart to the full version
It will be possible to use a Kickstart project without modifications in the full or Baseline version of IAR Embedded Workbench for MSP430.
The IAR XLINK Linker, IAR XLIB Librarian and IAR XAR Library Builder have been moved from the common\bin directory to the 430\bin directory. Related documentation files and code examples have been moved to 430\doc and 430\src\xlink respectively.
