Debug and Trace Support for Renesas 32-bit-RISC-V Microcontrollers

Hoehenkirchen, Germany—September 10, 2024 — Lauterbach’s TRACE32® development tools now support Renesas’ first 32-bit RISC-V® general-purpose Microcontroller group for cost-sensitive and low-power embedded applications. TRACE32® tools support includes debugging of the RISC-V processor core as well as read and write access to the chip’s internal flash memory.

The new R9A02G021 microcontroller (MCU) features a power-efficient and high-performance Renesas RISC-V 32-bit core. Renesas added several extensions that are very important for deeply embedded systems. The multiplication and bit-manipulation extensions and the integrated hardware divider speed up operations, while the additional compressed instructions further reduce code size, speed up execution and save power.

Lauterbach's TRACE32® development tools provide hardware-accelerated debugging of the RISC-V core and read/write access to the chip's internal flash memory. Embedded developers therefore do not need any additional flash programming hardware. The TRACE32® tools consist of the universal PowerView debugging and tracing software and debug and trace accelerator modules. While Lauterbach's intelligent PowerDebug modules provide the fastest download speeds and shortest response times available for efficient debugging and test automation, PowerTrace real-time trace modules provide complete visibility into what traceable processors and other cores of an embedded system are doing without impacting real-time performance in any way.

The unique OS-awareness feature of TRACE32® provides important insights into applications and the operating systems they run on. TRACE32® OS-aware debugging can query and display all OS objects such as threads, message queues, and more. This enables engineers to better understand how they behave and how they use chip resources.

“The first RISC-V microcontroller by Renesas combines performance and energy efficiency,” says Norbert Weiss, Managing Director at Lauterbach GmbH. “With the latest support of TRACE32®, engineers can use our market-leading debug and trace tools right from the start."

“TRACE32® from Lauterbach provides a complete set of hardware and software tools to simulate, analyze and streamline embedded system with our RISC-V MCUs,” said Markus Vomfelde, Director Business Development at Renesas. “With this new toolchain, customers designing with the R9A02G021 devices enjoy flexible and user-friendly design options for power-conscious, cost-sensitive applications based on the growing market for the RISC-V open-source instruction set architecture.”

Lauterbach’s TRACE32® development tools enable embedded developers to evolve their applications based on Renesas RISC-V MCUs even faster and easier.
