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, CortexT,
Renesas RXT 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.
Wifi based Segger JLINK, a new member of the J-Link family of debug probes With
USB and Wi-Fi interfaces, any software compatible with J-Link
can easily use the new model. Removing the physical connection between J-Link and the
host opens up a world of new possibilities: A robot, vehicle, drone, or other devices
with moving parts can be monitored or debugged on the move or from a distance. Physical
disconnection provides the ultimate in electrical isolation where desired, and J-Link
over Wi-Fi is perfect for accessing air-sealed environments.

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
and Linux.
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
J-Link.
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.

J-Trace
|
|
| |
|
|
| |
J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables
continuous streaming trace, lifting the limitations by internal buffers and slow
data transmission to give you all the insights you need to develop and optimize
your code.
J-Trace PRO can capture complete traces over long periods-thereby enabling the
recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when
the program flow 'runs off the rails' and stops in a fault state.
It also supports extended trace features, such as code
coverage (so engineers have visibility over
|
|
|
|
|
| |
which parts of the application code have
been executed) and execution profiling (providing
visibility as to which instructions have been executed and
how often-so hotspots can be addressed and optimization
opportunities identified). |
