Highlights
Service Pack 2.80.3- Device support for RX230 and RX231 has been added.
- New libraries have been added to handle option byte settings for different CPU core and flash memory combinations.
- Errors have been corrected in the C-SPY emulator driver.
- Renesas AP4 for RX is updated to V1.07.00.
- Errors have been corrected in the compiler.
- C-STAT
The add-on product C-STAT for static analysis is now supported. C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008. For more information, see the C-STAT Static Analysis Guide. - E2 Lite emulator support
C-SPY now supports the Renesas E2 Lite on-chip debugging emulator. - External flash support
You can now write data through the emulator to the external flash memory embedded in the system. As input, C-SPY is using external flash definition files (USD files) prepared with the External Flash Definition Editor tool from Renesas. - Parallel build
IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers. To enable parallel build, select Tools>Options>Project>Enable parallel build. - DSP intrinsic functions added
Intrinsic functions for DSP multiply-accumulate operations have been added. - Renesas AP4 for RX included
Renesas AP4 (former Applilet) is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with settings. It fully supports code generation for IAR Embedded Workbench for RX and the generated modules are incorporated via the IAR Project Connection mechanism. - Renesas Firmware Integration Technology (FIT)
Firmware Integration Technology (FIT) is a Renesas concept that emphasizes the simplification of embedding of peripheral function module drivers and improvement of portability between RX microcontrollers. A selection of these FIT modules are now included in the Information Center under Example projects. - Updated device support and example projects
SFR header files, linker configuration files, and device description files have been added for the latest Renesas devices together with various new example projects. - Updated user documentation
The IDE Project Management and Building Guide, and the C-SPY Debugging Guide have been updated to reflect the product changes.
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 from Renesas HEW or e2studio
Read the guide Migrating from Renesas to IAR Embedded Workbench if you are migrating from Renesas development tools. - Migration from UBROF
Read the guide Migrating from UBROF to ELF/DWARF if you are migrating from an IAR product using UBROF and IAR XLINK.
