SEGGER J-Link supports Cortex-M0+ based Atmel SAM D20

SEGGER enables debug support for Atmel’s new Cortex-M0+ based microcontroller SAM D20 from day one with the J-Link family of debug probes. The SAM D20 is the first device from Atmel based on the lowpower processor Cortex-M0+ from ARM. The Cortex-M0+ core has 4 hardware breakpoints which can be used in internal flash memory. The J-Link family can enhance the debug experience for the developer with the unlimited number of Flash Breakpoints. This feature, available in J-Link PLUS, J-Link ULTRA+, J-Link PRO and J-Trace, allows the developer to set an unlimited number of breakpoints in internal and external flash memory.

“As a result of our long term partnership with Atmel J-Link is the first debug probe supporting the SAM D20, Atmel’s first Cortex-M0+ based microcontroller”, says Dirk Akemann, Marketing Manager at SEGGER.

“The addition of the J-Link and the J-Link-based SAM-ICE for our recently launched SAM D20 Cortex M0+-based family gives customers market-leading debugging and programming capabilities required for their projects”, says Joerg Bertholdt, Director of Software and Tools, Atmel Corporation. “With strong eco-system partners such as SEGGER, designers can have the confidence that Atmel provides all the right tools for every design.”

About J-Link
The SEGGER J-Link is the most popular debug probe on the market. It is tool chain independent and works with commercial IDEs from: Atmel, Atollic, Coocox, Freescale, IAR, i-Systems, ImageCraft, KEIL, Mentor Graphics, Phyton, Rowley, Renesas, Tasking and others, as well as free GDB-based tool chains such as emIDE and EmBlocks. With the J-Link family, investments in the debug probe are likely preserved when changing compiler or even CPU architecture.

J-Link supports multiple CPU families, such as ARM 7, 9, 11, Cortex-M0, M0+, M1, M3, M4, R4, A5, A8, A9 as well as Renesas RX610, 620, 62N, 62T, 630, 631, 63N; there is typically no need to buy a new J-Link or new license when switching to a different CPU family or toolchain. SEGGER is also continuously adding support for additional cores, which in most cases, only requires a software/firmware update. Unlimited free updates are included with even the baseline model of the J-Link. SEGGER is excited to continue advanced development of its cutting edge embedded tool solutions to be utilized with pretty much any development environment you choose. All J-Links are fully compatible to each other, so an upgrade from a lower-end model to a higher-end model is a matter of a simple plug-andplay. Different architectures, same debug probe!
