IAR Systems, the future-proof supplier of software tools and services for embedded development, is pleased to announce the availability of IAR Embedded Workbench for Renesas RX 4.20.2 is Complete development toolchain to create smaller, faster, smarter code for all RX devices.
Release notes for IAR Embedded Workbench for Renesas RX version 4.20.2
Highlights
- Error correction
Errors have been corrected in the compiler, ielftool and in the linker configuration files for devices in groups RX651, RX65N, RX66N, RX72M, and RX72N that have on-chip expansion RAM starting at 0x0080000.

IAR Embedded Workbenchis a complete development toolchain including the highly optimizing IAR C/C++ Compiler and the feature-rich C-SPY Debugger. The software is complemented by native debugging and trace probes. The debug probe I-jet supports on-chip RAM buffered trace, in addition to fast JTAG/cJTAG/DAP debug and is complemented by the powerful trace probe I-jet Trace, which can livestream trace information for code coverage and profiling purposes. The new trace features include an updated trace control and status window that provides developers with full control of all active settings and the live trace status of the application. The C-SPY Debugger will decode trace and calculate coverage and profiling as the application executes, populating the respective windows on the fly. This live update enables developers to monitor everything from the available trace buffer to the number of covered instructions. In addition, function profiling makes it possible to see and analyze timing information for the functions in an application, while code coverage analysis shows the percentage of code that has been executed down to single instruction resolution. These combined capabilities offer a non-intrusive and easy-to-use code optimization tool.
Since the 1980's, IAR Systems and Renesashave had a strong partnership. Thanks to the longstanding collaboration, we are the only tool vendor able to deliver high-performing development tools for the entire lineup of Renesas microcontrollers.
With more than 4,000 supported Renesas devices, IAR Embedded Workbench supplies exceptional design flexibility for embedded developers working with the extensive Renesas product portfolio. The tools deliver outstanding performance and let our customers migrate easily between different architectures, and choose the one best suited for a specific application while using the same development tools. It also simplifies reuse of code.
In this video, you get a demo of how to work with integrated code analysis in IAR Embedded Workbench for RX. C-STAT static analysis and C-RUN runtime analysis are available as add-ons to bring code quality control to the desk of every developer.
IAR Systemssupplies future-proof software tools and services for embedded development, enabling companies worldwide to create the products of today and the innovations of tomorrow. Since 1983, IAR Systems' solutions have ensured quality, reliability and efficiency in the development of over one million embedded applications. The company is headquartered in Uppsala, Sweden and has sales and support offices all over the world.
