-Current as of Aug 30, 2008 - Duane Ellis
-==
-
-===================================================
-Overview - History
-
- Pre "tcl" - many commands in openocd where implimented as C
- functions. Post "tcl" (Jim-Tcl to be more exact, June 2008 ...) TCL
- became a bigger part of OpenOCD.
-
-One of the biggest changes is the introduction of 'target specific'
-commands. When every you create a target, a special command name is
-created specifically for that target.
-
- For example - in Tcl/Tk - if you create a button (or any other
- screen object) you can specify various "button configuration
- parameters". One of those parameters is the "object cmd/name"
- [ In TK - this is refered to as the object path ]. Later you
- can use that 'path' as a command to modify the button, for
- example to make it "grey", or change the color.
-
-In effect, the "path" function is an 'object oriented command'
-
-The TCL change in OpenOCD follows the same principle, you create a
-target, and a specific "targetname" command is created.
-
-There are two methods of creating a target.
-
- (1) Depricated: Using the old syntax Target names are autogenerated
- as: "target0", "target1" etc..
-
- (2) Using the new syntax, you can specify the name of the target.
-
-As most users will have a single JTAG target, and by default the
-command name will probably default to "target0", thus for reasons of
-simplicity the instructions below use the name 'target0'
-
-Overview - History *END*
-==================================================
-
-OpenOCD has the following 'target' or 'target-like' commands.
-
-(1) targets -(plural) lists all known targets and a little bit of
- information about each target, most importantly the target
- *COMMAND*NAME* (it also lists the target number)
-
-(2) target -(singular) used to create, configure list, etc the targets
-
-(3) target0 - the command object for the first target.
- Unless you specified another name.
-
-===================================================
-
-The "targets" (plural, 1 above) command has 2 functions.
-
-With a parameter, you can change the current command line target.
-
- NOTE: "with a parameter" is really only useful with 'multiple
- jtag targets' not something you normally encounter (ie: If you
- had 2 arm chips - sharing the same JTAG chain)
-
- # using a target name..
- (gdb) mon targets target0
- # or a target by number.
- (gdb) mon targets 3
-
-Or - plain, without any parameter lists targets, for example:
-
- (gdb) mon targets
- CmdName Type Endian ChainPos State
- -- ---------- ---------- ---------- -------- ----------
- 0: target0 arm7tdmi little 0 halted
-
-This shows:
- (a) in this example, a single target
- (b) target number 0 (1st column)
- (c) the 'object name' is target0 (the default name)
- (d) it is an arm7tdmi
- (e) little endian
- (f) The position in the JTAG chain
- (g) and is currently halted.
-
-====================================================
-
-The "target" (singular, 2 above) command has the following options:
-
- target create CMDNAME TYPE ... config options ...
- argv[0] = 'target'
- argv[1] = 'create'
- argv[2] = the 'object command'
- (normally, target0, see (3) above)
- argv[3] = the target type, ie: arm7tdmi
- argv[4..N] = configuration parameters
-
- target types
- Lists all supported target types.
- ie: arm7tdmi, xscale, fericon, cortex-m3
-
- The result TCL List of all known target types (and is human
- readable)
-
- target names
-
- Returns a TCL list of all known target commands (and is
- human readable)
-
- Example:
- foreach t [target names] {
- puts [format "Target: %s\n" $t]
- }
-
-
- target current
-
- Returns the TCL command name of the current target.
-
- Example:
- set ct [target current]
- set t [$ct cget -type]
-
- puts "Current target name is: $ct, and is a: $t"
-
-
- target number <VALUE>
-
- Returns the TCL command name of the specified target.
- For example
-
- set thename [target number $x]
- puts [format "Target %d is: %s\n" $x $thename]
-
- For instance, assuming the defaults
-
- target number 0
-
- Would return 'target0' (or whatever you called it)
-
- target count
-
- Returns the larget+1 target number.
- For example:
-
- set c [target count]
- for { set x 0 } { $x < $c } { incr x } {
- # Assuming you have this function..
- print_target_details $x
- }
-
-====================================================
-
-"target0" - (#3 above) the "Target Object" command.
-
- Once a target is 'created' a command object by that targets name is
- created, for example
-
- target create BiGRed arm7tdmi -endian little -chain-position 3
-
-Would create a [case sensative] "command" BiGRed
-
-If you use the old [deprecated] syntax, the name is automatically
-generated and is in the form:
-
- target0, target1, target2, target3, .... etc.
-
-====================================================
-
-** Target CREATE, CONFIGURE and CGET options **
-
-The commands:
-
- target create CMDNAME TYPE [configure-options]
- CMDNAME configure [configure-options]
- CMDNAME cget [configure-options]
-
-In the 'create' case, one is creating the target and can specify any
-number of configuration parameters.
-
-In the 'CMDNAME cget' case, the goal is to query the target for a
-specific configuration option.
-
-In the 'CMDNAME configure' case, one can change the setting.
-[Not all things can, or should be changed]
-
-In the above, the "default" name target0 is 'target0'
-
-Example:
-
- From the (gdb) prompt, one can type this:
-
- (gdb) mon target0 configure -endian big
-
- And change target0 to 'big-endian'. This is a contrived example,
- specifically for this document - don't expect changing endian
- 'mid-operation' to work you should set the endian at creation.
-
-Known options [30/august/2008] are:
-
-[Manditory 'create' Options]
- -type arm7tdmi|arm720|etc ...
- -chain-position NUMBER
- -endian ENDIAN
-
-Optional
-
- -event EVENTNAME "tcl-action"
- -reset RESETACTION
- -work-area-virt ADDR
- -work-area-phys ADDR
- -work-area-size ADDR
- -work-area-backup BOOLEAN
-
-[Hint: To get a list of avaialable options, try this]
-
- (gdb) mon target0 cget -BLAHBLAHBLAH
-
- the abov causes an error - and a helpful list of valid options.
-
-==================================================
-** Example Target Configure Query **
-
-One can query any of the above options at run time, for example:
-
- (gdb) mon target0 cget -OPTION [param]
-
-Example TCL script
-
- # For all targets...
- set c [target count]
- for { set x 0 } { $x < $c } { incr x ] {
- set n [target number $x]
- set t [$n cget -type]
- set e [$n cget -endian]
- puts [format "%d: %s, %s, endian: %s\n" $x $n $t $n]
- }
-
-Might produce:
- 0: pic32chip, mips_m4k, endain: little
- 1: arm7, arm7tdmi, endian: big
- 2: blackfin, bf534, endian: little
-
-Notice the above example is not target0, target1, target2 Why? Because
-in this contrived multi-target example - more human understandable
-target names might be helpful.
-
-For example these two are the same:
-
- (gdb) mon blackfin configure -event FOO {puts "Hi mom"}
-
-or:
- (gdb) mon [target number 2] configure -event FOO {puts "Hi mom"}
-
-In the second case, we use [] to get the command name of target #2, in
-this contrived example - it is "blackfin"
-
-====================================================
-** TWO Important Configure Options Are: **
-
-Two important configuration options are:
-
- "-event" and "-reset"
-
-The "-reset" option specifies what should happen when the chip is
-reset, for example should it 'halt', 're-init', or what.
-
-The "-event" option less you specifiy a TCL command to occur when a
-specific event occurs.
-
-====================================================
-** Target Events * Overview **
-
-At various points in time - certian 'target' events happen. You can
-create a custom event action to occur at that time.
-
-For example - after reset, the PLLs and CLOCKs may need to be
-reconfigured, or perhaps the SDRAM needs to be re-initialized
-
-Often the easiest way to do that is to create a simple script file
-containing the series of (mww [poke memory]) commands you would type
-by hand, to reconfigure the target clocks. You could specify the
-"event action" like this:
-
- (gdb) mon target0 configure -event reset-init "script cfg.clocks"
-
-In the above example, when the event "reset-init" occurs, the
-"action-string" will be evaluated as if you typed it at the console
-
-Option1 -
-
- The simple approach (above) is to create a script file with
- lots of "mww" (memory write word) commands to configure your
- targets clocks and/or external memory.
-
-Option2 -
-
- You can instead create a fancy Tcl procedure and invoke that
- procedure instead of sourcing a file.
-
- [Infact, "script" is a TCL procedure that loads a file]
-
-==================================================
-
-** Target Events * Details **
-
-There are many events one could use, to get a current list of events
-type the following invalid command, you'll get a helpful "runtime
-error" message, see below: [list valid as of 30/august/2008]
-
- (gdb) mon target0 cget -event FAFA
-
-Runtime error, file "../../../openocd23/src/helper/command.c", line 433:
- -event: Unknown: FAFA, try one of: old-pre_reset,
- old-gdb_program_config, old-post_reset, halted,
- resumed, resume-start, resume-end, reset-start,
- reset-assert-pre, reset-assert-post,
- reset-deassert-pre, reset-deassert-post,
- reset-halt-pre, reset-halt-post, reset-wait-pre,
- reset-wait-post, reset-init, reset-end,
- examine-start, examine-end, debug-halted,
- debug-resumed, gdb-attach, gdb-detach,
- gdb-flash-write-start, gdb-flash-write-end,
- gdb-flash-erase-start, gdb-flash-erase-end,
- resume-start, resume-ok, or resume-end
-
-NOTE:
-
- The event-names "old-*" are deprecated and exist only to help old
- scripts continue to function, and the old "target_script" command
- to work. Please do not rely on them.
-
-These are some other important names.
-
- gdb-flash-erase-start
- gdb-flash-erase-end
- gdb-flash-write-start
- gdb-flash-write-end
-
- These occur when GDB/OpenOCD attempts to erase & program the FLASH
- chip via GDB.
-
- For example - some PCBs may have a simple GPIO pin that acts like
- a "flash write protect" you might need to write a script that
- disables "write protect"
-
-==================================================
-
-** How to get a list of current event actions **
-
-To get a list of current 'event actions', type the following command:
-
- (gdb) mon target0 eventlist
-
- Event actions for target (0) target0
-
- Event | Body
- ------------------------- | ----------------------------------------
- old-post_reset | script event/sam7x256_reset.script
- ***END***
-
-Here is a simple example for all targets:
-
- (gdb) mon foreach x [target names] { $x eventlist }
-
-The above uses some TCL tricks:
-
- (a) foreach VARIABLE LIST BODY
-
- (b) to generate the list, we use [target names]
-
- (c) the BODY, contains $x - the loop variable
- and expands to the target specific name
-
-====================================================
-
-Recalling the earlier discussion - the "object command" there are
-other things you can do besides "configure" the target.
-
-Note: Many of these commands exist as "global" commands, and they also
-exist as target specific commands.
-
-For example, the "mww" (memory write word) operates on the current target
-if you have more then 1 target, you must switch
-
-In contrast to the normal commands, these commands operate on the
-specific target. For example, the command "mww" writes data to the
-*current* command line target.
-
-Often, you have only a single target - but if you have multiple
-targets (ie: a PIC32 and an at91sam7 - your reset-init scripts might
-get a bit more complicated, ie: you must specify which of the two
-chips you want to write to. Writing 'pic32' clock configuration to an
-at91sam7 does not work)
-
-The commands are: [as of 30/august/2008]
-
- TNAME mww ADDRESS VALUE
- TNAME mwh ADDRESS VALUE
- TNAME mwb ADDRESS VALUE
- Write(poke): 32, 16, 8bit values to memory.
-
- TNAME mdw ADDRESS VALUE
- TNAME mdh ADDRESS VALUE
- TNAME mdb ADDRESS VALUE
- Human 'hexdump' with ascii 32, 16, 8bit values
-
- TNAME mem2array [see mem2array command]
- TNAME array2mem [see array2mem command]
-
- TNAME curstate
- Returns the current state of the target.
-
-
- TNAME examine
- See 'advanced target reset'
- TNAME poll
- See 'advanced target reset'
- TNAME reset assert
- See 'advanced target reset'
- TNAME reset deassert
- See 'advanced target reset'
- TNAME halt
- See 'advanced target reset'
- TNAME waitstate STATENAME
- See 'advanced target reset'

+
+@subsection Commands
+@cindex Commands
+OpenOCD has the following 'target' or 'target-like' commands:
+
+@enumerate
+@item
+@b{targets (plural)} - lists all known targets and a little bit of information about each
+ target, most importantly the target *COMMAND*NAME* (it also lists the target number);

+@cindex target
+@item
+@b{target0} - the command object for the first target. Unless you specified another name.
+@cindex target0
+@end enumerate
+
+@subsubsection Targets Command
+@cindex Targets Command
+The "targets" command has 2 functions:
+
+@itemize
+@item
+With a parameter, you can change the current command line target.
+
+NOTE: "with a parameter" is really only useful with 'multiple JTAG targets' not something
+you normally encounter (ie: If you had 2 arm chips - sharing the same JTAG chain).
+@verbatim
+# using a target name.
+(gdb) mon targets target0
+# or a target by number.
+(gdb) mon targets 3
+@end verbatim
+@cindex with a parameter
+@item
+Plain, without any parameter lists targets, for example:
+
+@verbatim
+(gdb) mon targets
+ CmdName Type Endian ChainPos State
+-- ---------- ---------- ---------- -------- ----------
+ 0: target0 arm7tdmi little 0 halted
+@end verbatim
+
+This shows:
+@enumerate a
+@item
+in this example, a single target;
+@item
+target number 0 (1st column);
+@item
+the 'object name' is target0 (the default name);
+@item
+it is an arm7tdmi;
+@item
+little endian;
+@item
+the position in the JTAG chain;
+@item
+and is currently halted.
+@end enumerate
+@cindex without any parameter
+@end itemize
+
+@subsubsection Target Command
+@cindex Target Command
+
+The "target" command has the following options:
+@itemize
+@item
+target create
+
+@verbatim
+ target create CMDNAME TYPE ... config options ...
+ argv[0] = 'target'
+ argv[1] = 'create'
+ argv[2] = the 'object command'
+ (normally, target0, see (3) above)
+ argv[3] = the target type, ie: arm7tdmi
+ argv[4..N] = configuration parameters
+@end verbatim
+@item
+target types
+
+ Lists all supported target types; ie: arm7tdmi, xscale, fericon, cortex-m3.
+ The result TCL list of all known target types (and is human readable).
+@item
+target names
+
+ Returns a TCL list of all known target commands (and is human readable).
+
+ Example:
+@verbatim
+ foreach t [target names] {
+ puts [format "Target: %s\n" $t]
+ }
+@end verbatim
+@item
+target current
+
+ Returns the TCL command name of the current target.
+
+ Example:
+@verbatim
+ set ct [target current]
+ set t [$ct cget -type]
+
+ puts "Current target name is: $ct, and is a: $t"
+@end verbatim
+@item
+target number <VALUE>
+
+ Returns the TCL command name of the specified target.
+
+ Example
+@verbatim
+ set thename [target number $x]
+ puts [format "Target %d is: %s\n" $x $thename]
+@end verbatim
+ For instance, assuming the defaults
+@verbatim
+ target number 0
+@end verbatim
+ Would return 'target0' (or whatever you called it)
+@item
+target count
+
+ Returns the larget+1 target number.
+
+ Example:
+@verbatim
+ set c [target count]
+ for { set x 0 } { $x < $c } { incr x } {
+ # Assuming you have this function..
+ print_target_details $x
+ }
+@end verbatim
+@end itemize
+
+@subsubsection Target0 Command
+@cindex Target0 Command
+The "target0" command (the "Target Object" command):
+
+Once a target is 'created' a command object by that targets name is created, for example
+@verbatim
+ target create BiGRed arm7tdmi -endian little -chain-position 3
+@end verbatim
+
+Would create a [case sensitive] "command" BiGRed
+
+If you use the old [deprecated] syntax, the name is automatically
+generated and is in the form:
+@verbatim
+ target0, target1, target2, target3, ... etc.
+@end verbatim
+
+@subsubsection Target CREATE, CONFIGURE and CGET Options Command
+@cindex Target CREATE, CONFIGURE and CGET Options Command
+The commands:
+@verbatim
+ target create CMDNAME TYPE [configure-options]
+ CMDNAME configure [configure-options]
+ CMDNAME cget [configure-options]
+@end verbatim
+@itemize
+@item
+In the 'create' case, one is creating the target and can specify any
+number of configuration parameters.
+@item
+In the 'CMDNAME configure' case, one can change the setting [Not all things can, or should be changed].
+@item
+In the 'CMDNAME cget' case, the goal is to query the target for a
+specific configuration option.
+@end itemize
+
+In the above, the "default" name target0 is 'target0'.
+
+ Example:
+
+ From the (gdb) prompt, one can type this:
+
+@verbatim
+ (gdb) mon target0 configure -endian big
+@end verbatim
+
+ And change target0 to 'big-endian'. This is a contrived example,
+ specifically for this document - don't expect changing endian
+ 'mid-operation' to work you should set the endian at creation.
+
+Known options [30/august/2008] are:
+@itemize
+@item
+[Mandatory 'create' Options]
+ @itemize
+ @item
+ type arm7tdmi|arm720|etc ...
+ @item
+ chain-position NUMBER
+ @item
+ endian ENDIAN
+ @end itemize
+@item
+Optional
+ @itemize
+ @item
+ event EVENTNAME "tcl-action"
+ @item
+ reset RESETACTION
+ @item
+ work-area-virt ADDR
+ @item
+ work-area-phys ADDR
+ @item
+ work-area-size ADDR
+ @item
+ work-area-backup BOOLEAN
+ @end itemize
+@end itemize
+Hint: To get a list of available options, try this:
+@verbatim
+ (gdb) mon target0 cget -BLAHBLAHBLAH
+@end verbatim
+
+ the above causes an error - and a helpful list of valid options.
+
+One can query any of the above options at run time, for example:
+@verbatim
+ (gdb) mon target0 cget -OPTION [param]
+@end verbatim
+
+Example TCL script
+
+@verbatim
+ # For all targets...
+ set c [target count]
+ for { set x 0 } { $x < $c } { incr x ] {
+ set n [target number $x]
+ set t [$n cget -type]
+ set e [$n cget -endian]
+ puts [format "%d: %s, %s, endian: %s\n" $x $n $t $n]
+ }
+@end verbatim
+
+Might produce:
+
+@verbatim
+ 0: pic32chip, mips_m4k, endain: little
+ 1: arm7, arm7tdmi, endian: big
+ 2: blackfin, bf534, endian: little
+@end verbatim
+
+Notice the above example is not target0, target1, target2 Why? Because in this contrived multi-target example -
+more human understandable target names might be helpful.
+
+For example these two are the same:
+
+@verbatim
+ (gdb) mon blackfin configure -event FOO {puts "Hi mom"}
+@end verbatim
+
+or:
+
+@verbatim
+ (gdb) mon [target number 2] configure -event FOO {puts "Hi mom"}
+@end verbatim
+
+In the second case, we use [] to get the command name of target #2, in this contrived example - it is "blackfin".
+
+Two important configuration options are:
+
+ "-event" and "-reset"
+
+The "-reset" option specifies what should happen when the chip is reset, for example should it 'halt', 're-init',
+or what.
+
+The "-event" option less you specify a TCL command to occur when a specific event occurs.
+
+@subsection Target Events
+@cindex Target Events
+
+@subsubsection Overview
+@cindex Overview
+At various points in time - certain 'target' events happen. You can create a custom event action to occur at that time.
+For example - after reset, the PLLs and CLOCKs may need to be reconfigured, or perhaps the SDRAM needs to be re-initialized.
+Often the easiest way to do that is to create a simple script file containing the series of (mww [poke memory]) commands
+you would type by hand, to reconfigure the target clocks. You could specify the "event action" like this:
+
+@verbatim
+ (gdb) mon target0 configure -event reset-init "script cfg.clocks"

+
+In the above example, when the event "reset-init" occurs, the "action-string" will be evaluated as if you typed it at the
+console:
+@itemize
+@item @b{Option1} - The simple approach (above) is to create a script file with lots of "mww" (memory write word) commands
+ to configure your targets clocks and/or external memory;
+@item @b{Option2} - You can instead create a fancy TCL procedure and invoke that procedure instead of sourcing a file [In fact,
+ "script" is a TCL procedure that loads a file].
+@end itemize

+There are many events one could use, to get a current list of events type the following invalid command, you'll get a helpful
+"runtime error" message, see below [list valid as of 30/august/2008]:
+
+@verbatim
+(gdb) mon target0 cget -event FAFA
+Runtime error, file "../../../openocd23/src/helper/command.c", line 433:
+ -event: Unknown: FAFA, try one of: old-pre_reset,
+ old-gdb_program_config, old-post_reset, halted,
+ resumed, resume-start, resume-end, reset-start,
+ reset-assert-pre, reset-assert-post,
+ reset-deassert-pre, reset-deassert-post,
+ reset-halt-pre, reset-halt-post, reset-wait-pre,
+ reset-wait-post, reset-init, reset-end,
+ examine-start, examine-end, debug-halted,
+ debug-resumed, gdb-attach, gdb-detach,
+ gdb-flash-write-start, gdb-flash-write-end,
+ gdb-flash-erase-start, gdb-flash-erase-end,
+ resume-start, resume-ok, or resume-end
+@end verbatim
+
+NOTE: The event-names "old-*" are deprecated and exist only to help old scripts continue to function, and the old "target_script"
+command to work. Please do not rely on them.
+
+These are some other important names:
+@itemize
+@item gdb-flash-erase-start
+@item gdb-flash-erase-end
+@item gdb-flash-write-start
+@item gdb-flash-write-end
+@end itemize
+
+These occur when GDB/OpenOCD attempts to erase & program the FLASH chip via GDB. For example - some PCBs may have a simple GPIO
+pin that acts like a "flash write protect" you might need to write a script that disables "write protect".
+
+To get a list of current 'event actions', type the following command:
+
+@verbatim
+ (gdb) mon target0 eventlist
+
+ Event actions for target (0) target0
+
+ Event | Body
+ ------------------------- | ----------------------------------------
+ old-post_reset | script event/sam7x256_reset.script
+@end verbatim
+
+Here is a simple example for all targets:
+
+@verbatim
+ (gdb) mon foreach x [target names] { $x eventlist }
+@end verbatim
+
+The above uses some TCL tricks:
+@enumerate a
+@item foreach VARIABLE LIST BODY
+@item to generate the list, we use [target names]
+@item the BODY, contains $x - the loop variable and expands to the target specific name
+@end enumerate
+
+Recalling the earlier discussion - the "object command" there are other things you can
+do besides "configure" the target.
+
+Note: Many of these commands exist as "global" commands, and they also exist as target
+specific commands. For example, the "mww" (memory write word) operates on the current
+target if you have more then 1 target, you must switch. In contrast to the normal
+commands, these commands operate on the specific target. For example, the command "mww"
+writes data to the *current* command line target.
+
+Often, you have only a single target - but if you have multiple targets (ie: a PIC32
+and an at91sam7 - your reset-init scripts might get a bit more complicated, ie: you must
+specify which of the two chips you want to write to. Writing 'pic32' clock configuration
+to an at91sam7 does not work).
+
+The commands are [as of 30/august/2008]:
+@verbatim
+ TNAME mww ADDRESS VALUE
+ TNAME mwh ADDRESS VALUE
+ TNAME mwb ADDRESS VALUE
+ Write(poke): 32, 16, 8bit values to memory.
+
+ TNAME mdw ADDRESS VALUE
+ TNAME mdh ADDRESS VALUE
+ TNAME mdb ADDRESS VALUE
+ Human 'hexdump' with ascii 32, 16, 8bit values
+
+ TNAME mem2array [see mem2array command]
+ TNAME array2mem [see array2mem command]
+
+ TNAME curstate
+ Returns the current state of the target.
