@cindex gdb_port
First port on which to listen for incoming GDB connections. The GDB port for the
first target will be gdb_port, the second target will listen on gdb_port + 1, and so on.
+@item @b{gdb_breakpoint_override} <@var{hard/soft/disabled}>
+@cindex gdb_breakpoint_override
+hard/soft/disabled - force breakpoint type for gdb 'break' commands.
+The raison d'etre for this option is to support GDB GUI's without
+a hard/soft breakpoint concept where the default OpenOCD and
+GDB behaviour is not sufficient. Note that GDB will use hardware
+breakpoints if the memory map has been set up for flash regions.
+
+This option replaces older arm7_9 target commands that addressed
+the same issue.

CFI flashes require the number of the target they're connected to as an additional
argument. The CFI driver makes use of a working area (specified for the target)
to significantly speed up operation.
@var{chip_width} and @var{bus_width} are specified in bytes.

@node Target library
@chapter Target library
@cindex Target library
These commands are specific to ARM7 and ARM9 targets, like ARM7TDMI, ARM720t,
ARM920t or ARM926EJ-S.
@itemize @bullet
-@item @b{arm7_9 sw_bkpts} <@var{enable}|@var{disable}>
-@cindex arm7_9 sw_bkpts
-Enable/disable use of software breakpoints. On ARMv4 systems, this reserves
-one of the watchpoint registers to implement software breakpoints. Disabling
-SW Bkpts frees that register again.
-@item @b{arm7_9 force_hw_bkpts} <@var{enable}|@var{disable}>
-@cindex arm7_9 force_hw_bkpts
-When @option{force_hw_bkpts} is enabled, the @option{sw_bkpts} support is disabled, and all
-breakpoints are turned into hardware breakpoints.
@item @b{arm7_9 dbgrq} <@var{enable}|@var{disable}>
@cindex arm7_9 dbgrq
Enable use of the DBGRQ bit to force entry into debug mode. This should be
Informing gdb of the memory map of the target will enable gdb to protect any
flash area of the target and use hardware breakpoints by default. This means
-that the OpenOCD option @option{arm7_9 force_hw_bkpts} is not required when
+that the OpenOCD option @option{gdb_breakpoint_override} is not required when
using a memory map.
To view the configured memory map in gdb, use the gdb command @option{info mem}
@item @b{load_binary}
@cindex load_binary
use @option{load_image} command with same args
+@item @b{target}
+@cindex target
+@option{target} no longer take the reset_init, reset_run, run_and_halt, run_and_init. The @option{reset} command
+always does a @option{reset run} when passed no arguments.
@item @b{dump_binary}
@cindex dump_binary
use @option{dump_image} command with same args
this config option has been removed, simply adding @option{init} and @option{reset halt} to
the end of your config script will give the same behaviour as using @option{daemon_startup reset}
and @option{target cortex_m3 little reset_halt 0}.
+@item @b{arm7_9 sw_bkpts}
+@cindex arm7_9 sw_bkpts
+On by default. See also @option{gdb_breakpoint_override}.
+@item @b{arm7_9 force_hw_bkpts}
+@cindex arm7_9 force_hw_bkpts
+Use @option{gdb_breakpoint_override} instead. Note that GDB will use hardware breakpoints
+for flash if the gdb memory map has been set up(default when flash is declared in
+target configuration).
@item @b{run_and_halt_time}
@cindex run_and_halt_time
This command has been removed for simpler reset behaviour, it can be simulated with the
GDB issues software breakpoints when a normal breakpoint is requested, or to implement
source-line single-stepping. On ARMv4T systems, like ARM7TDMI, ARM720t or ARM920t,
-software breakpoints consume one of the two available hardware breakpoints,
-and are therefore disabled by default. If your code is running from RAM, you
-can enable software breakpoints with the @option{arm7_9 sw_bkpts enable} command. If
-your code resides in Flash, you can't use software breakpoints, but you can force
-OpenOCD to use hardware breakpoints instead: @option{arm7_9 force_hw_bkpts enable}.
+software breakpoints consume one of the two available hardware breakpoints.
