Hilden, Germany – December 21st, 2012 – After a recent upgrade to the J-Link hardware and further improvements to the software, the industry leading J-Link has been subjected to a flash programming speed comparison against various debug probes. The results show, that even the base model of the J-Link outperforms the competition. All tests have been performed on the same target chip, STM32 with blank flash memory.
The speed tests have been made with different debug probes and software under the same test conditions. The I-jet and ST-Link V2 were tested with IAR Embedded Workbench for ARM. The ULINKpro was tested with KEIL uVision. The J-Link base model of the 2013 hardware (v9) was tested with the IAR Embedded Workbench for ARM, KEIL uVision, and the J-Link Commander version 4.59a (test utility included freely with the J-Link related software package). All tests have been performed by placing a 512 KB program into the flash memory of a blank STM32F417IG microcontroller connected via SWD interface. Tests via JTAG interface gave similar results.
“Flash Download performance has a significant impact on debug turn around times. This Flash-Download performance comparison shows once again that J-Link plays in a league of its own, as even our base model clearly outperforms every other emulator we have tested with”, says Rolf Segger, Founder, and CTO of SEGGER.

The SEGGER J‑Link is the industry-standard for ARM debug emulators, supported by all major tool chains for ARM cores. The SEGGER J-Link is tool chain independent and will work with IDEs from: Atmel, Atollic, Freescale, IAR, KEIL, Mentor Graphics, Rowley, Renesas, Tasking, Phyton and others. In addition to those listed above; any RDI compliant debugger can be used with the optional RDI module, and any GDB compliant debugger with the free GDB-Server. Therefore; as projects change, a different compiler/debugger may have to be used. With the J-Link family, investments (monetary and learning curve) in development/ production tools are preserved. Setup of a J‑Link is done in mere minutes.
J-Link supports multiple CPU families, such as ARM 7, 9, 11, Cortex-M0, M1, M3, M4, R4, A5, A8, A9, Renesas RX in a single model; there is typically no need to buy a new J-Link or new license when switching to a different CPU family or tool-chain. 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-and-play.
