+@node Target library
+@chapter Target library
+@cindex Target library
+
+OpenOCD comes with a target configuration script library. These scripts can be
+used as-is or serve as a starting point.
+
+The target library is published together with the openocd executable and
+the path to the target library is in the OpenOCD script search path.
+Similarly there are example scripts for configuring the JTAG interface.
+
+The command line below uses the example parport configuration scripts
+that ships with OpenOCD, then configures the str710.cfg target and
+finally issues the init and reset command. The communication speed
+is set to 10kHz for reset and 8MHz for post reset.
+
+
+@smallexample
+openocd -f interface/parport.cfg -c "jtag_khz 10 8000" -f target/str710.cfg -c "init" -c "reset"
+@end smallexample
+
+
+To list the target scripts available:
+
+@smallexample
+$ ls /usr/local/lib/openocd/target

@node Commands
@chapter Commands
@cindex commands
@cindex debug_level
Display or adjust debug level to n<0-3>
+@item @b{fast} [@var{enable/disable}]
+@cindex fast
+Default disabled. Set default behaviour of OpenOCD to be "fast and dangerous". For instance ARM7/9 DCC memory
+downloads and fast memory access will work if the JTAG interface isn't too fast and
+the core doesn't run at a too low frequency. Note that this option only changes the default
+and that the indvidual options, like DCC memory downloads, can be enabled and disabled
+individually.
+
+The target specific "dangerous" optimisation tweaking options may come and go
+as more robust and user friendly ways are found to ensure maximum throughput
+and robustness with a minimum of configuration.
+
+Typically the "fast enable" is specified first on the command line:
+
+openocd -c "fast enable" -c "interface dummy" -f target/str710.cfg

+By default the target memory map is sent to gdb, this can be disabled by
the following openocd config option:
@smallexample
-gdb_memory_map enable
+gdb_memory_map disable
@end smallexample
For this to function correctly a valid flash config must also be configured
in openocd. For speed also configure a valid working area.
To view the configured memory map in gdb, use the gdb command @option{info mem}
All other unasigned addresses within gdb are treated as RAM.
+GDB 6.8 and higher set any memory area not in the memory map as inaccessible,
+this can be changed to the old behaviour by using the following gdb command.
+@smallexample
+set mem inaccessible-by-default off
+@end smallexample

If @option{gdb_flash_program enable} is also used, gdb will be able to
program any flash memory using the vFlash interface.
