IAR Embedded Workbench for RISC-V supports RV32 and RV32E 32-bit RISC-V cores and extensions, including RISC-V P extension for Packed-SIMD instructions and RISC-V B extension. The support for custom extensions helps when working with designing custom cores with exact definitions for an application or a product.

- 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 requires a license renewal. This can be performed by starting the IAR License Manager and selecting License→Check for License Renewal, or by using the Light License Manager with the command LightLicenseManager renew YOUR_PROD.EW.
- 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.
- Known limitations
- C++ RTTI and exceptions are not supported by the compiler
The exception and interrupt catch functionality that can be enabled under Project>Options>I-jet>Breakpoints>Catch exceptions requires that the selected device has implemented triggers for instruction counter, interrupt catch, and exception catch. Consult the device vendor manual for details
Flash breakpoints are not supported in this release
#pragma vector and automatic population of an interrupt vector are not supported for all devices, and interrupt vectors must then be set up manually
Some of the flash loaders included in this release are macro-based and are to be considered temporary. Until a flash loader executing in RAM is implemented, the performance with respect to download speed will be limited
IAR Embedded Workbench for RISC-V is not ABI-compliant with the RISC-V specification, and linking with libraries compiled with gcc is not supported in this release
The code generation for the B-extensions Zba, Zbb, Zbc, and Zbs is not fully optimized in this release
- Network licenses
For network licenses, IAR Embedded Workbench for RISC-V version 2.10.1 and later requires IAR License Server Tools version 2.18.2 or later. For more information, see technical note TN21842. The latest IAR License Server Tools are backwards compatible with previous IAR Embedded Workbench versions.
- 64-bit Windows support
IAR tools such as the compiler and debugger now run as Windows 64-bit programs. 32-bit Windows is not supported.
- Incompatibility with Embedded workbench for Arm 9.10.1
If Embedded workbench for RISC-V is installed after Embedded Workbench for Arm 9.10.1 (All other versions are fine) in the same installation directory and then uninstalled it will break the Arm installation. To fix this issue run the Embedded workbench for Arm installer again to repair the installation.
