About this document
Assumptions
This document assumes that you already have a solid knowledge of the following:
• The software tools used for building your application (assembler, linker, C compiler).
• The C programming language.
• The target processor.
• DOS command line.
If you feel that your knowledge of C is not sufficient, we recommend The C Programming Lan-
guage by Kernighan and Richie (ISBN 0–13–1103628), which describes the standard in C pro-
gramming and, in newer editions, also covers the ANSI C standard.
How to use this manual
This manual explains all the functions and macros that the product offers. It assumes you have
a working knowledge of the C language. Knowledge of assembly programming is not required.

Chapter 1
Why J-Link OB?
The J-Link on-board (J-Link OB) was designed in order to provide a low-cost, space-saving
and on-board alternative to the general J-Link, for eval board manufacturers. J-Link OB can
be used with the same software package as the general J-Links and can be used with the
same utilities (as far as the feature set of the J-Link OB supports this)
Note
It is not allowed to use J-Link-OB-STM32F072-128KB (Cortex-M) for stand-alone em-
ulators.
