3.3 J-Link GDB Server
The GNU Project Debugger (GDB) is a freely available and open source debugger. It
can be used in command line mode, but is also integrated in many IDEs like emIDE
or Eclipse.
J-Link GDB Server is a remote server for GDB making it possible for GDB to connect
to and communicate with the target device via J-Link. GDB Server and GDB commu-
nicate via a TCP/IP connection, using the standard GDB remote protocol. GDB Server
receives the GDB commands, does the J-Link communication and replies with the
answer to GDB.
With J-Link GDB Server debugging in ROM and Flash of the target device is possible
and the Unlimited Flash Breakpoints can be used.
It also comes with some functionality not directly implemented in the GDB. These can
be accessed via monitor commands, sent directly via GDB, too.
The GNU Project Debugger (GDB) is a freely available debugger, distributed under
the terms of the GPL. The latest Unix version of the GDB is freely available from the
GNU committee under: http://www.gnu.org/software/gdb/download/
J-Link GDB Server is distributed free of charge.
3.3.1 J-Link GDB Server CL (Windows, Linux, Mac)
J-Link GDB Server CL is a commandline-only version of the GDB Server.
The command line version is part of the Software and Documentation Package and
also included in the Linux and MAC versions.
Except for the missing GUI, J-Link GDB Server CL is identical to the normal version.
All sub-chapters apply to the command line version, too.
