J-Link downloads

The J-Link software & documentation pack gives you the USB drivers needed for your system, a number of utilities as well as a dynamically linkable library (DLL on Windows) used by most of the IDEs and debuggers using J-Link.

Also included are a number of sample setup scripts for devices needing one as well as documentation. The package can be downloaded and used free of charge by any owner of a J-Link, J-Trace or Flasher ARM, Flasher RX model.

It is updated frequently. All utilities and features included can be used on any of these units without the need for an additional license, with the exception of J-Flash, RDI and "Unlimited Flash Breakpoints", which require a separate license on most units (not J-Link ULTRA+, J-Link PRO or J-Link PLUS which include all licenses)

J-Link software & documentation pack can also be used with J-Link KS, SAM-ICE, mIDASLink, DIGI JTAG Link and any other licensed J-Link compatible emulator.

Software for Linux ARM systems 

Software and documentation pack for Linux ARM systems V5.00k [7,738 kb]
md5 checksum: 397dad747dd4093aa1ac25cb5ecb5de5
  Note: This package is only needed in the special case of J-Link being controlled by a Linux system which is running on an ARM hardware (so J-Link is connected via USB/Ethernet to this ARM system that is running Linux). In case J-Link is just connected to a PC running Linux, the "J-Link software & documentation pack for Linux" is the correct package.

Note: This package comes without any support.
