SEGGER J-Link debugger support for Cortex-M85 device

Working closely with the Renesas hardware and software development teams, SEGGER swiftly supplied a working J-Link programming and debug solution very early in the RA8M1 group development cycle. The first solution supplied was capable of debugging on the Renesas VHDL simulator running in their design offices in Japan. Due to the remote location and very restricted access, SEGGER was able to use their remote tunnelling capability to bring up J-Link debugging from SEGGER's headquarters in Germany.

The latest release of J-Link debugger software offers the usual very fast debug features including download to the RA8M1 on-chip flash and external OSPI flash along with hardware/software breakpoints as well as streaming instruction trace when using J-Trace PRO.

“Having access to the J-Link debug probes so early in the RA8 series development cycle has enabled us to release the first commercially available Cortex-M85 MCUs with a fully functional ecosystem,” says Andy Beeson, Product Manager at Renesas Electronics. “This includes the Renesas RA Flexible Software Package (FSP), TrustZone and IDEs, with J-Link at the very heart of it.”

“SEGGER is pleased that Renesas chose J-Link to be the debug probe of choice for the extremely powerful and impressive range of RA8 series devices,” says Ivo Geilenbruegge, Managing Director of SEGGER. “We look forward to adding further software products to RA8 product groups in the near future.”

In addition to the new device now being supported by SEGGER’s J-Link debug probes and J-Trace streaming trace probes, it is now also supported by SEGGER’s Flasher in-circuit programmers.

The Flasher family of programmers are fast, robust, reliable, and easy to use. Using Turbo mode, programming speed is extremely fast. Whether the focus is on size, flexibility, portability, security, or mass production, SEGGER has the perfect programmer for the task at hand.
