Stellaris chips have a procedure for restoring the chip to
what's effectively the "as-manufactured" state, with all the
non-volatile memory erased. That includes all flash memory,
plus things like the flash protection bits and various control
words which can for example disable debugger access. clearly,
this can be useful during development.

Most of this patch updates documentation and comments for various
Luminary boards, supporting two bug fixes by helping to make sense
of the current mess:
- Recent rev C lm3s811 eval boards didn't work. They must use
the ICDI layout, which sets up some signals that the older
boards didn't need. This is actually safe and appropriate
for *all* recent boards ... so just make "luminary.cfg" use
the ICDI layout.
- "luminary-lm3s811.cfg", was previously unusable! No VID/PID;
and the wrong vendor string. Make it work, but reserve it
for older boards where the ICDI layout is wrong.
- Default the LM3748 eval board to "luminary.cfg", like the
other boards. If someone uses an external JTAG adapter, all
boards will use the same workaround (override that default).
The difference between the two FT2232 layouts is that eventually
the EVB layout will fail cleanly when asked to enable SWO trace,
but the ICDI layout will as cleanly be able to enable it. Folk
using "luminary.cfg" with Rev B boards won't see anything going
wrong until SWO support is (someday) added.

Semihosting enables code running on an ARM target to use the

all initialize OK now, but the arm*20 parts don't do the "extra"

The semantics of "-work-area-virt 0" (or phys) changed with
the patch to require specifying physical or virtrual work
area addresses. Specifying zero was previously a NOP. Now
it means that address zero is valid.
This patch addresses three related issues:
- MMU-less processors should never specify work-area-virt;
remove those specifications. Such processors include
ARM7TDMI, Cortex-M3, and ARM966.
- MMU-equipped processors *can* specify work-area-virt...
but zero won't be appropriate, except in mischievous
contexts (which hide null pointer exceptions).
Remove those specs from those processors too. If any of
those mappings is valid, someone will need to submit a
patch adding it ... along with a comment saying what OS
provides the mapping, and in which context. Example,
say "works with Linux 2.6.30+, in kernel mode". (Note
that ARM Linux doesn't map kernel memory to zero ...)
- Clarify docs on that "-virt" and other work area stuff.
Seems to me work-area-virt is quite problematic; not every
operating system provides such static mappings; if they do,
they're not in every MMU context...

XSVF improvements:
- Layer parts of XSVF directly over SVF, calling svf_add_statemove()
instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
requirements (which it doesn't).
This should improve XSTATE handling a lot; it removes most users of
jtag_add_statemove(), and the comments about how it should really do
what svf_add_statemove() does.
- Update XSTATE logic to be a closer match to the XSVF spec. The main
open issue here is (still) that this implementation doesn't know how
to build and submit paths from single-state transitions ... but now
it will report that error case.
- Update the User's Guide to mention the two utility scripts for
working with XSVF, and to mention the five extension opcodes.
Handling of state transition paths is, overall, still a mess. I think
they should all be specified as paths not unlike SVF uses, and compiled

This makes the documentation a closer match to "help" output:
- "pathmove" somehow was not documented in the User's Guide
- "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width"
are new; both needed descriptions.
- Removed two undocumented and fairly useless script mechanisms:
* production/production_info/production_test ... using it,
requires replacing everything; so having it adds no value.
* cpu ... way out of date; hopeless to keep that current
Note that anyone using that "production" stuff already defines
their own procedures, and can keep using them with no change.

- The guess-rev.sh script is now a tweaked version of "setlocalversion" as
seen in Linux, U-Boot, and various other projects. When it finds source
control support (git, hg, svn) it uses IDs from there. Else (specific
to this project) it reports itself as "-snapshot", e.g. from gitweb.
I verified this new "guess-rev.sh" script runs under Cygwin.
- Also update the generic version strings to be like "0.3.0-dev" (during
development) instead of the very long "0.3.0-in-development". These also
show up in the PDF docs. For better tracking, we might eventually change
these strings to include the version IDs too.
- Change the startup banner version strings so they include the guess-rev
output. Development and release versions with GIT will be like
Open On-Chip Debugger 0.3.0-dev-00282-g7191a4f-dirty (2009-10-05-20:57)
Open On-Chip Debugger 0.3.0 (2009-10-05-20:57)

The model is that this fires after scanchain verification, when it's
safe to call "jtag tapenable $TAPNAME". So it will fire as part of
non-error paths of "init" and "reset" command processing. However it
will *NOT* trigger during "jtag_reset" processing, which skips all
scan chain verification, or after verification errors.
ALSO:
- switch DaVinci chips to use this new mechanism
- log TAP activation/deactivation, since their IDCODEs aren't verified
- unify "enum jtag_event" scripted event notifications
- remove duplicative JTAG_TAP_EVENT_POST_RESET

* add a missing diagnostic on a potential ETB setup error
* prefix any diagnostics with "ETB"
- ETM
* make "etm status" show ETM hardware status too, instead of
just traceport status (which previously was fake, sigh)
- Docs
* flesh out "etm tracemode" docs a bit
* clarify "etm status" ... previously it was traceport status
* explain "etm trigger_percent" as a *traceport* option
ETM+ETB tracing still isn't behaving, but now I can see that part of
the reason is that the ETB turns itself off almost immediately after
being enabled, and before collecting any data.

Change the handling of the "-ircapture" and "-irmask" parameters
to be slightly more sensible, given that the JTAG spec describes
what is required, and that we already require that conformance in
one place. IR scan returns some bitstring with LSBs "01".
- First, provide and use default values that satisfy the IEEE spec.
Existing TAP configs will override the defaults, but those parms
are no longer required.
- Second, warn if any TAP gets set up to violate the JTAG spec.
It's likely a bug, but maybe not; else this should be an error.
Improve the related diagnostics to say which TAP is affected.
And associated minor fixes/cleanups to comments and diagnostics.

only expose the registers which are actually present. They
could be missing for two basic reasons:
- This version might not support them at all; e.g. ETMv1.1
doesn't have some control/status registers. (My sample of
ARM9 boards shows all with ETMv1.3 support, FWIW.)
- The configuration on this chip may not populate as many
registers as possible; e.g. only two data value comparators
instead of eight.
Includes a bugfix in the "etm info" command: only one of the
two registers is missing on older silicon, so show the first
one before bailing.
Update ETM usage docs to explain that those registers need to be
written to configure what is traced, and that some ETM configs
are not yet handled. Also, give some examples of the kinds of
constrained trace which could be arranged.

Erase logic:
- command invocation
+ treat "nand erase N" (no offset/length) as "erase whole chip N"
+ catch a few more bogus parameter cases, like length == 0 (sigh)
- nand_erase() should be static
- on error
+ say which block failed, and if it was a bad block
+ don't give up after the first error; try to erase the rest
- on success, say which nand device was erased (name isn't unique)
Device list ("nand list"):
- say how many blocks there are
- split summary into two lines
- give example in the docs
Doc tweaks:
- Use @option{...} for DaVinci's supported hardware ECC options
For the record, I've observed that _sometimes_ erasing bad blocks causes
failure reports, and that manufacturer bad block markers aren't always
erasable (even when erasing their blocks doesn't trigger an error report).

Work around that (for now) by re-assigning the desired

Initial support for disassembling Thumb2 code. This works only for
Cortex-M3 cores so far. Eventually other cores will also need Thumb2
support ... but they don't yet support any kind of disassembly.
- Update the 16-bit Thumb decoder:
* Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added
by ARMv6. (It already seems to treat CPY as MOV.)
* Understand CB, CBNZ, WFI, IT, and other opcodes added by
in Thumb2.
- A new Thumb2 instruction decode routine is provided.
* This has a different signature: pass the target, not the
instruction, so it can fetch a second halfword when needed.
The instruction size is likewise returned to the caller.
* 32-bit instructions are recognized but not yet decoded.
- Start using the current "UAL" syntax in some cases. "SWI" is
renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM".
- Define a new "cortex_m3 disassemble addr count" command to give
access to this disassembly.

This patch adds support for the Luminary Micro LM3S9B90 target and

Add "jtag names" command, mirroring "target names" but returning
TAP names instead of target names. This starts letting TAPs be
manipulated in scripts ... much like what works now for targets.
It's a bit limited just yet, since "jtag cget $TAPNAME" doesn't
expose all TAP attributes. "$TARGETNAME cget" is more functional.

Warn when people (or scripts) use numeric identifiers for TAPs,
instead of dotted.name values. We want this usage to go away,
so that for example adding more TAPs doesn't cause config scripts
to break because some sequence number changed.
It's been deprecated since late 2008, but putting a warning on
this should help us remove it (say, in June 2010) by helping to
phase out old (ab)usage in config scripts.
Other than in various config files, the only code expecting such
a number was the almost unused str9xpec driver. This code was
changed to use the TAP it was passed, instead of making its own
dubious lookup and ignoring that TAP.

This should be my last significant update of the User's Guide for
this release. Mostly it's a rework of the config file chapter's
presentation of board and target config files.
- Give the new path for scripts!
- Move board-config material out of the target-config section
- Add more board-config info, notably for reset-init events
- Link out of the board-config section to NAND, NOR, and Reset chapters
- Emphasize target input vs. output naming conventions
- Other textual improvements

- Clean the config file guidelines a bit:
* They're for all users, not just integrators
* Reference the interface config chapter
* Don't emphasize command line usage here
* Tweak board and target config introductory text

OpenOCD license (GNU GPLv2 with no exceptions).
Make that clear where that build option is presented, and don't

fine for personal use, of course.)

OpenOCD doesn't actually *need* to be keeping all TCP ports

Rework the "Simple Configuration Files" chapter so it's more
of a quick-start "how to set up your project" tutorial:
- Say how to hook up the JTAG adapter. This will help new
users, and in any case is worth spelling out somewhere.
- Streamline the previous rather haphazard presentation,
filling in some missing holes along the way:
* Suggest "project directory" structure
* Introduce new term, "user config" file (openocd.cfg)
* Talk about more options for openocd.cfg contents
* ... and about creating new config files
* Add new topic, project-specific utilities (+examples)
- Remove too-short, yet duplicative, chapter 19

Note that I tried this on an arm920t, but it didn't work. Set bits,
then examined them and they weren't set. And it didn't seem to act

Update the "General Commands" (a.k.a. "random stuff") chapter,
and associated chunks of other text:
- Switch to @deffn and review everything that's documented
- Improve descriptions of reset events, with reference to
the setup.tcl code which issues them.
- Move one zy1000-specific command to that driver's doc.
- There is no "script" command; remove its doc.
NOTE: Some things missing from this bit of work are:
1- Reviewing the code to catch various *missing* functions,
mostly from "target.c"
2- Alphabetizing and organizing. This chapter is a real
grab-bag with no evident focus or structural principle.
3- Hole-filling and bugfixing with respect to messaging/logging.
Example, what principle could possibly justify the tcl command
output going into the server output/log instead of just the
telnet session?
4- Not just for this chapter ... but there should be a section
with descriptions of all the supported image file formats,
so every image command can just reference that section.

Convert the Interface/Dongle Config chapter's section
on drivers to use the @deffn syntax, and integrate the
presentation of the driver-specific commands with the
relevant driver. Alphabetize.
Cross-checked against the code ... several adapters were
not listed, and a few commands weren't.
(Maintainers for the versaloon and zy1000 drivers would be
good candidates to add the commands missing from those
sections...)
git-svn-id: svn://svn.berlios.de/openocd/trunk@2035 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Convert the str9xpec driver info to use @deffn; alphabetize;
add the missing part_id command.
Convert the mflash support to use @deffn; alphabetize.

Update docs for most of the remaining commands in jtag.c:
- switch to @deffn
- these are just the "low level" JTAG commands
- resolve much goofage!
* remove docs for non-existent commands
* add missing docs for some existing commands
* fix incorrect docs for some commands
- just index TAP states overall, not individually
- current name is "RUN/IDLE" not "IDLE"
Cross checked against the source.
This also creates an "Interface Drivers" section, analagous to how
(NOR) Flash and NAND drivers are presented; that's not yet sorted.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2014 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Rework the TAP creation documentation.
- Try to use "TAP" not "tap" everywhere; it's an acronym.
- Update the associated "target config files" section:
* reference the "TAP Creation" chapter for details
* simplify: reference interesting multi-tap config files
* let's not forget CPU configuration (*before* workspace setup)
* streamline it a bit
* move that workspace-vs-mmu issue to a better location
- Clean up TAP creation doc mess
* switch to @deffn
* (re)organize the remaining stuff
* reference the "Config File Guidelines" chapter
- Tweak the "Target Configuration" chapter
* rename as "CPU configuration"; unconfuse vs. target/*.cfg
* bring out that it's not just there for GDB
* move TAP events to the TAP chapter, where they belong (bugfix)
git-svn-id: svn://svn.berlios.de/openocd/trunk@2013 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- change SWJDP_IR/DR_APACC to DAP_IR/DR_APACC to conform with ARM_ADI docs.
- add swjdp->memaccess_tck field and code for extra tck clocks before accessing memory bus
- Set default memaccess value to 8 for Cortex-M3.
- Add dap memaccess command.
- document all armv7 dap cmds.
- Original patch submitted by Magnus Lundin [lundin@mlu.mine.nu].
git-svn-id: svn://svn.berlios.de/openocd/trunk@2005 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Remove two sections about deprecated/removed commands, documenting
them briefly in the chapter on deprecated/removed commands. The
"working_area" command just duplicated text; "jtag_device" wasn't
listed in that chapter before.
Also start de-emphasizing those commands. Don't index them, and
include a disclaimer that their documentation may start to vanish
about a year after the code does (e.g. in January 2010).
git-svn-id: svn://svn.berlios.de/openocd/trunk@1986 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Uplevel the arch commands to be a chapter; they really
don't fit in the "general commands" category.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1977 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Fix minor goofage in previous doc updates:
* The ETM dummy driver name is "dummy" not "etm_dummy";
re-alphabetize.
* DCC trace message mode "charmsg" is a format type
(and what Linux needs)
git-svn-id: svn://svn.berlios.de/openocd/trunk@1976 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Various updates, mostly small/formatting changes:
* Small content tweaks:
- Re-title: "OpenOCD User's Guide".
- For users, URLS for latest doc and SparkFun forum
- Mention GIT-SVN
* Fix some front-matter goofage, matching texinfo docs:
- "paragraphintent" location matters
- put release version/date description with the copyright
* Fix some other stuff matching texinfo docs:
- no tabs
- tweak some refs and anchors
* whitespace-at-end-o-line fixes
