Using the J-Link DLL

4.7.1

What is the JLink DLL?

The J-LinkARM.dll is a standard Windows DLL typically used from C or C++, but also Visual
Basic or Delphi projects. It makes the entire functionality of the J-Link / J-Trace available
through the exported functions. The functionality includes things such as halting/stepping
the ARM core, reading/writing CPU and ICE registers and reading/writing memory. There-
fore, it can be used in any kind of application accessing a CPU core.
4.7.2

Updating the DLL in third-party programs

The JLink DLL can be used by any debugger that is designed to work with it. Some debuggers
are usually shipped with the J-Link DLL already installed. Anyhow it may make sense to
replace the included DLL with the latest one available, to take advantage of improvements
in the newer version.
