Command Strings - Segger J-Link User Manual

5.12 Command strings

The behavior of the J-Link can be customized via command strings passed to the
JLinkARM.dll which controls J-Link. Applications such as the J-Link Commander, but
also the C-SPY debugger which is part of the IAR Embedded Workbench, allow pass-
ing one or more command strings. Command line strings can be used for passing
commands to J-Link (such as switching on target power supply), as well as customize
the behavior (by defining memory regions and other things) of J-Link. The use of
command strings enables options which can not be set with the configuration dialog
box provided by C-SPY.
