SEGGER J-Links are the most widely used line of debug
probes available today. They've been proven for more than
10 years with over 250,000 units sold, including OEM
versions and on-board solutions. This popularity stems from
the unparalleled performance, extensive feature set, large
number of supported CPUs, and compatibility with all
popular development environments.
With up to 3 MBytes/s download speed to RAM and record
breaking flashloaders, as well as the ability to set an
unlimited number of breakpoints in flash memory of MCUs,
the J-Link debug probes are undoubtedly the best choice to
optimize your debugging and flash programming experience.
J-Link debug probes support all ARM 7/9/11, Cortex™, Renesas RX™ CPUs and are supported by all major IDEs such
as IAR EWARM, Keil MDK,Rowley CrossWorks, Atollic
TrueSTUDIO, IAR EWRX,Renesas HEW, Renesas e2studio,
including GDB based IDEs, and many others.
Debug smarter and faster with J-Link debug probes!
Hardware features like Ethernet interface, USB full- /
high-speed interface, etc. are J-Link model specific
features which can not be updated or changed by software
Price does not include VAT or Sales Tax which may be applicable in some
Cortex-M3,4 cores only
ARM 7/9 cores only
The download speeds listed here are the peak download speeds that can be
achieved by the particular J-Link model.The actual download speed may be lower
as it depends on various factors, such as, but not limited to: The selected
debug interface & speed, the CPU core and its operating frequency, other devices
in the JTAG chain in case JTAG is used as target interface.
For customers who want to build their own applications
using J-Link, and for IDE vendors who implement J-Link
support for their IDE, SEGGER offers a J-Link SDK which
comes with the J-Link DLL + API documentation +
implementation samples. The SDK is available for Windows
Remote Server Debugging in Tunnel Mode
The J-Link Remote Server effortlessly debugs target
hardware and application in remote locations over TCP/IP
as if the target was on the developer's desk. Taking this
concept to the next level, SEGGER offers a tunnel mode
for remote debugging anywhere in the world.
Tunnel mode initiates the connection sending the serial
number of the J-Link to the tunnel server. The J-Link DLL
then is capable of creating a tunnel connection via the
server just by using the serial number of the target
Support engineers can debug unwieldy hardware at the
customer's site without having to travel there, just by
sending a J-Link. Distributed development teams can share
early prototypes even in remote locations.
SEGGER announces J-Link Real Time Terminal (RTT) which
speeds up bidirectional communication between the target
system and the development computer by at least an order of
magnitude. This new technology brings printf-style
debugging and system verification functionality to any
application. The only thing needed to use J-Link RTT is a
CPU with a debug interface that allows background memory
access; no extra pins are required.
SEGGER announces J-Scope, their new data visualization
software for the industry standard J-Link family of debug
probes. J-Scope is an application to analyze and visualize
data on a microcontroller in real-time, while the target is
running. It providesa real-time, accurate representation of
the sampled variables enabling the engineer to better
understand the embedded application.
J-Scope is based on the newly introduced J-Link HSS (High
Speed Sampling) feature, which makes it possible to
continuously sample variables at extremely high speeds
without affecting the real-time nature of the embedded
device. Using the standard debug interface, it does not
require any extra resources on the target such as memory,
CPU time or extra pins.
