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 SCC interface no longer supported
Microsoft SCC-compatible version control systems are no longer supported by IAR Embedded Workbench.
- 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\<user name>\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.
- Network licenses
For network licenses, this version of the IAR Embedded Workbench requires IAR License Server Tools version 2.15.4 or later. For more information see technical note TN21842. The latest IAR License Server Tools are backwards-compatible with previous IAR Embedded Workbench versions.
- Migration
The debugger flash loader mechanism was changed in version 5.40. If your project uses a default flash loader with no extra parameters, no migration work is needed.
If the debugger detects that your project uses a non-default flash loader or that it uses extra parameters, it will revert to the default flash loader for your device. In addition a.board
file will be created in the project directory. If necessary the.board
file can be edited and used by manually overriding the default flash loader with this project-specific.board
file.If you are migrating from version 4.x to this version, we recommend that you read the IAR Embedded Workbench Migration Guide for ARM.
- Object format
The object format used in the compiler, assembler, linker, and debugger is based on the ARM ABI standard version 2.10 with ELF/DWARF 4. For the standard definition, see the ARM Application Binary Interface.
