J-Link
JTAG/SWD Emulator with USB interface
 J-Link is a USB powered JTAG emulator supporting a large
number of CPU cores.
Based on a 32-bit RISC CPU, it can communicate at high speed with the
supported target CPUs. J-Link is used around the world in tens of
thousand places for development and production (flash programming)
purposes.
J-Link support is integrated in most professional IDEs such as IAR,
Keil, Rowley and many others.
Along with the OEM version (such as IAR J-Link, ATMEL SAM-Ice and
others) more than 60,000 J-Links have been sold so far, making J-Link
probably the most popular emulator for ARM cores and the de-facto
standard.

Available Software Packages
J-Link Flash Breakpoints
The J-Link software contains an additional feature, called Flash
Breakpoints.
Flash breakpoints allow the user to set an unlimited
number of software breakpoints when debugging in flash memory.
This feature is also available for
J-Link RDI.
J-Flash
J-Flash is a PC software running on Windows 2000/XP systems,
which enables you to program your Flash EEPROM devices via the
On-Chip Debug connector (JTAG) on your target system.
J-Link GDB Server
The J-Link GDB Server is a remote server for the GDB.
The GDB
and GDB Server communicate via a TCP/IP connection, using the
standard GDB remote serial protocol.
The GDB Server translates
the GDB monitor commands into J-Link commands.
J-Link SDK
The J-Link DLL is a standard Windows DLL typically used from "C"
(Visual Basic or Delphi projects are also doable).
It makes the
entire functionality of J-Link available thru the exported
functions.
J-Link Flash SDK
An enhanced version of the J-Link SDK, which contains additional
API functions for flash programming.
The additional API functions
(Prefixed JLINKARM_FLASH) allow erasing and programming the internal
flash memory of many ARM 7/9 and Cortex-M3 MCUs.
J-Link ARM RDI
The J-Link ARM RDI software is an RDI interface for J-Link.
It
makes it possible to use J-Link with any RDI compliant debugger.
