+== GDB ==
+
+GDB is an open source debugger that is included in the !CodeSourcery development package.
+
+Using a terminal program such as Hyperterm to communicate with the 825 console at the “#” prompt type:
+
+gdbserver :''port'' ''progname'' [''args''] &  (where port is the TCP/IP port to be used, and programe is the name of the program to be debugged)
+
+For example:
+
+gdbserver :10000 cardbas 788IDS.77X &
+
+This will start the gdbserver process:
+
+184
+
+Process cardbas created; pid = 185
+
+Listening on port 10000
+
+From the PC you may then start debugging by selecting the “Debug” perspective and then clicking the “Bug” icon in Eclipse.
+
+For example, the terminal will show:
+
+Remote debugging from host 90.1.1.216
+
+Breakpoints may be set by double-clicking the border just to the left of a program line in the editor.
+
+F5 – Step Into (If stopped at a function call, this will step into the function)
+
+F6 – Step Over (If stopped at a function call, this will step over to the next statement)
+
+F8 – Resume (If stopped this will resume running)
+
+The “Variables” window will automatically show the local variables that are in use.
+
+Right-click in the “Variables” window and select “Add global Variables…” to select global variables to monitor. These will not appear until the next break.
+
+To stop the debugging session from !CodeSourcery click the red square icon. The application being debugged and the gdbserver will automatically exit.
+
+The terminal window will show:
+
+Killing inferior
+
+It is also possible to set gdbserver to attach to an already executing process.
+
+Determine the existing process ID first by using the PS command.
+
+gdbserver :''port'' – attach ''pid'' &  (where ''port ''is the TCP/IP port number and ''pid ''is the process ID)
+
+For example:
+
+gdbserver :10000 –attach 187 &
+
+When using the attach method stopping the debugging session from Eclipse may not stop gdbserver or the application.
