Segger adds DLM and Trustzone to in-circuit programmers

Working with Renesas, Segger has added device lifecycle management (DLM) and Trustzone partitioning to its Flasher in-circuit programmers which offers high speed programming of Renesas RA4 and RA6 microcontrollers with Arm Cortex-M33 cores.

Flasher owners can install the new features by downloading software from Segger’s website. The updates are available free of charge, with no license cost and no hidden fees.

The Flasher programmer can be seamlessly integrated into a standard production workflow without the need for third-party tools. Once configured, the Segger Flasher operates as a standalone device.

According to Bernd Westhoff, Renesas’ marketing director for the RA family, Segger offers the first support of Arm TrustZone and Renesas’ DLM.

Segger Flashers are a family of professional in-circuit programmers, designed to be used in service environments, prototype programming and for mass production. They program the flash (non-volatile) memory of microcontrollers and SoCs as well as QSPI (quad serial peripheral interface) flashes.

The programmers work with a PC or in standalone mode. They connect via USB and/or Ethernet, and can be used with Linux, macOS and Windows.

The Cortex-M33-based devices in the Renesas RA4 and RA6 families of microcontrollers build upon the security features provided by Arm’s Trustzone-M functionality to offer additional levels of embedded security. The DLM defines the different phases of a device’s life and controls the capabilities of the debug interface as well as the boot mode serial interface. At production time, the DLM state can be configured to lockdown debug and/or boot mode access, helping to keep the system and the software it contains secure.

Segger Microcontroller has three decades of experience in embedded systems, producing RTOS and software libraries, J-Link and J-Trace debug and trace probes, a line of Flasher in-system programmers and software development tools. 

Segger’s emPower OS provides an RTOS with software libraries including communication, security, data compression and storage and user interface software.

The company was founded by Rolf Segger in 1992, is privately held. It has a US office in the Boston area and branch operations in Silicon Valley, Shanghai and the UK, with distributors on most continents.
