It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

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...

We currently do something unusual: version codes in config.in get
updated after the release, which means that "git describe" won't
match up to development version labels. Comment that trouble spot.
We can fix this by switching away from the major/minor/micro type
release numbering, as various other projects have done. The major
numbers basically don't tend to change, and doing a good job with
micro versions is so annoying that they rarely change either.
Contrast releases to git snapshot tarballs. Mention that
releases have some quality-improvement focus, with special
non-"dev" version IDs. Explain more about version IDs,
using "openocd -v" to see them, etc;
Make release milestone info be less specific about timing,
and presume we have both a merge window and an RC stage.
Rework the release process information to match reality a
bit more closely. Reference the version.sh script (in one
place the wrong script was referenced). Bugfix branches
get special treatment, while non-bugfix releases are more
or less what *defines* being the mainline branch.

Update documentation to reflect GIT methodology. Rewrite release.sh
script to use appropriate process. With this update, tools/release.sh
can be used for producing private release tags on local branches.
The documentation still needs work, but their use for v0.3.x should
help rectify the deficiences.
Bit 5 shouldn't be used. Remove all support for modifying it.
Matches the exception vector table, of course ... more than one
bootloader uses that non-vector to help distinguish valid boot
images from random garbage in flash.
The register names are perversely not documented as zero-indexed,
so rename them to match that convention. Also switch to lowercase
suffixes and infix numbering, matching ETB and EmbeddedICE usage.
Update docs to be a bit more accurate, especially regarding what
the "trigger" event can cause; and to split the issues into a few
more paragraphs, for clarity.
Make "configure" helptext point out that "oocd_trace" is prototype
hardware, not anything "real".

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
to the bitstrings later ... so that we can actually make sense of the
paths. (And see the extra clocks, detours through RUN, etc.)

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

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

* clarify "etm status" ... previously it was traceport status
* explain "etm trigger_percent" as a *traceport* option

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.

- 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.

written to configure what is traced, and that some ETM configs
are not yet handled. Also, give some examples of the kinds of

+ catch a few more bogus parameter cases, like length == 0 (sigh)
- nand_erase() should be static
- on error

+ 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)

- 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

* This has a different signature: pass the target, not the

The instruction size is likewise returned to the caller.

TAP names instead of target names. This starts letting TAPs be

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.

Doc update: say "jtag newtap ... -disable" records the
state after exiting the RESET state, matching the only
implementation we're working with so far (TI ICEpick-C).
Matching code updates. Now we can be sure that the
"enabled" flag value is correct after JTAG resets.

Minor updates to the text about reset configuration:
- Mention a new point that it interacts with JTAG routers;
- Talk about a "user" config file not a "system" one;
- Remove text from the "reset_config" description; instead,
cross-reference the more extensive text earlier.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2243 b42882b7-edfa-0310-969c-e2dbd0fdcd60
OpenOCD doesn't actually *need* to be keeping all TCP ports
active ... creating security issues in some network configs.
Instead, let config file specify e.g. "tcl_port 0" (or gdb_port,
telnet_port) to disable that particular remote access method.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2240 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Move the discussion of the "scan_chain" command up to go with
the presentation of that topic in the TAP declaration chapter.
This makes the presentation of the TAP and target lists be
parallel, which will be something of an aid to understanding
that they are different (and how).
git-svn-id: svn://svn.berlios.de/openocd/trunk@2223 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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
Nudge packagers a bit more strongly to send patches (including
config files) upstream.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2204 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Update "arm9tdmi vector_catch" command description to highlight both
use cases (display configuration, or first change that config) and
to explain a bit more about what this is: an alternative to using
hardware breakpoint resources.
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
as if vector triggering was noticed, either.
Also some minor unrelated tweaks: @ignore some unused or don't-use
event names; fix a few typos; tweak chip-specific reset descriptions.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2203 b42882b7-edfa-0310-969c-e2dbd0fdcd60
other server configuration. Explain what it's about;
reference the related "$target_name curstate" method.
Update "poll" output to report whether background polling
is enabled or not.
Also fix a small typo; PC's have "complementary" tools.
Some have also "complimentary" ones; but not all.

- Don't let disabled TAPs be set as the current target
- Improve "targets" output:
* Remove undesirable "chain position" number; we discourage using them
* TAP and Target column updates:
+ make them long enough for current usage
+ improve labels, removing guesswork
+ "TapName" label patches scan_chain output
* Highlight the "current" target
* Display "tap disabled" as a new pseudo-state
* Update docs accordingly

Rework chapter 12 (CPU configuration) to use @deffn, match
the code more closely, and present things more clearly.
Includes the *current* list of targets.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2097 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Various minor tweaks for the User's guide.
- Fix various minor (but repeated) typographic goofs;
- Talk about TAP "declaration" not "creation" (they exist
even if OpenOCD never learns about their board);
- Encourage board.cfg for reset config, not target.cfg
- Fill in some missing information (e.g. x16_as_x8)
- Add a cross reference to the FAQ on TAP ordering;
- Unclutter the concept index a bit (re core-specific commands)
- Provide a bit more info about TAP states
git-svn-id: svn://svn.berlios.de/openocd/trunk@2096 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2039 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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;

git-svn-id: svn://svn.berlios.de/openocd/trunk@2034 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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

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).

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
git-svn-id: svn://svn.berlios.de/openocd/trunk@1975 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Provide basic documentation on the ARM ETM and ETB trace commands.
Fix minor goofs in registration of the ETM commands; and whitespace
issues in the proof-of-concept oocd_trace code. (Plus include a
ref to Dominic's email saying that it's just proof-of-concept code.)
Note that I'm still not sure whether the ETM support works. But
documenting how it's expected to work should help sort out which
behaviors are bugs, which will help get bugs patched.
ZW: whitespace changes were split out of this patch but will follow.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1945 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Make it so the magic "reset_config" keywords can be provided in any
order. This eliminates needless error paths, and makes it easier
to define things at the right level (adapter, board, target).
It also includes two other behavioral changes:
(1) When "handle_reset_config" sees a parameter error, it
exits without changing anything. This is best viewed
as a bugfix. (Old behavior: restore defaults, even if
they weren't previously active.)
(2) Only the behaviors that were explicitly specified get
changed. (Old behavior: everything else gets reset to
the "default".) So for example you can now specify SRST
drive requirements without saying anything about the
three unrelated topics you previously had to specify.
That second one might cause confusion for any configs that end
up calling "reset_config" twice, so it will deserve to be called
out in the release notes. (There were no such configurations in
the current OpenOCD source tree.)
Update docs accordingly. Note that at least some versions of
the texi-to-html tools can't handle "@xref{with spaces}", but
those work properly in PDF and in the info files.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1944 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Provide basic documentation for some of the other flash drivers.
avr ... looks incomplete, may work with one AVR8 microcontroller
ecosflash ... can't find docs
lpc288x ... an NXP part, driver seems lpc2888-specific
ocl ... some arm7/arm9 thing, can't find docs
pic32mx ... looks incomplete, for PIC32MX (MIPS 4K) devices
tms470 ... for TI TMS470 parts
Still seems to be mostly arm7tdmi... several of these have no
users in the current tree.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1941 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Start converting the architecture-specific commands to @deffn format,
reviewing against the code.
* armv4_5 disassemble ... now documented; although Jazelle code
is not handled
* It's "armv4_5 core_state" not "core_mode"; although Jazelle state
is not handled
* arm7/9 "debug" commands ... now with other arm7_9 commands, no
longer in a separate section
* arm926ejs cp15 ... previous description was broken, it matched
the code for arm920t instead
* Have separate subsections for ARMv4/ARMv5, ARMv6, and ARMv7; the
latter are new
* Move core-specific descriptions into sub-subsections under those
architectures; XScale and ARM11 descriptions are new
The new XScale and ARM11 command descriptions surely need elaboration
and review. ARM CP15 operation descriptions in general seem to be
confused and incomplete.

Continue updating the NOR flash coverage to use @deffn syntax, so the
commands have more consistent presentation and formatting. This
reorganizes information and updates its presentation, except where
the information didn't really match the code.
This patch updates the main commands, and finishes making the section
structure parallel the NAND presentation. Of note:
- The "flash fill[whb] addr value length" commands are now documented.
- The "flash bank" command is now presented much earlier
- Explicit mention is made that NOR flash should be read using just
standard memory access commands, like "mdw" and "dump_image".
git-svn-id: svn://svn.berlios.de/openocd/trunk@1938 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Start updating the NOR flash coverage to use @deffn syntax, so the
commands have more consistent presentation and formatting. This
reorganizes information and updates its presentation, except where
the information didn't really match the code.
This patch updates most of the driver specific support, creating one
new (and alphabetized!) section just for driver-specific data, where
previously that data was split over up to three sections. Of note:
- The at91sam7 docs were a bit out of date with respect to the code.
- The "str9xpec" stuff still deserves some work. For now, it sits
in its own subsection; pretty messy.
- Likewise the "mflash" stuff. That's a parallel infrastructure,
and is now in a section of its own.
- The "mass_erase" commands for the Cortex M3 chips got turned into
footnotes. IMO, they should vanish sometime; they're superfluous.
- There are still a bunch of undocumented NOR drivers. Examples:
avr(8), tms470, pic32mx, more.
Plus there are a handful of minor tweaks to the NAND docs (to help make
the NOR and NAND presentations be parallel); the "Command Index" has
been renamed as the "Command and Driver Index"; reference TI instead
of Luminary Micro in several places.

Fix a bunch of PDF generation bugs in the texi:
* The "overfull" warnings are basically complaints about lines
that are too long, so they ran off the right margin of the
PDF documentation and turn into a "black blot".
* The "underfull" warnings are basically complaints about lines
that look ugly when they get filled, because the tokens are
so long that the line-break algorithm can't do anything good.
In a few cases the simplest fix seemed to be to use more appropriate
texi commands.
In other cases the fix was a content bugfix: "ocd_" not "openocd_";
and many of those "target variants" actually aren't recognized.

Update the "Reset Configuration" information in the User's guide:
- Convert to @deffn syntax
- Move tutorial text from command descriptions into new sections
- Describe several different types of JTAG-visible reset
- Expand descriptions of configuration tweaks for SRST and TRST
- Link to the "reset" command, and vice versa
- Bugfix the "reset_config" description (it didn't match the code)
Plus, be more proscriptive: do it in board config files, except for
the oddball cases where that won't work. (Current target.cfg files
seem to have much goofage there; several seem board-specific.)

Doc (mostly) update for jtag_khz:
- switch to @deffn syntax
- add entry for "jtag_rclk"
- move deprecated "jtag_speed" into collection of deprecated calls
And for ft2232, don't be the only adapter to *log* an error if RTCK
is requested; it's already reported properly, like any other nonfatal
command parameter. "jtag_rclk" just works as expected, without any
scarey messages.

Make startup for the various server ports be quiet, unless
debugging is active: don't emit needless scarey messages.
Update the relevant documentation and its references:
- For these port commands ... cover the default values;
convert to @deffn syntax; include their use outside of
the configuration stage; and alphabetize.
Similar updates to the rest of that small chapter:
- Highlight that there even *IS* a configuration stage, after
which some command functionality is no longer available.
- For GDB commands ... convert to @deffn syntax; alphabetize;
include a missing command (!); add missing helptext (!) for
one non-missing command; update relevant cross-references
and index entries.

Update two oddball NAND commands to work with {offset, length}
instead of block numbers, matching the other commands as well
as usage in U-Boot and the Linux-MTD utilities.
Document them accordingly. Update the single in-tree use of
those commands (sheevaplug).
ALSO:
(a) Document the current 2 GByte/chip ceiling for NAND chipsize.
(32 bit offset/length values can't represent 4 GBytes.) Maybe
after the upcoming release, the code can switch to 64-bits.
(b) The "nand check_bad_blocks" should report "bad" blocks. They
are not "invalid" blocks; they're "bad" ones.
(c) Tweak the "nand info" command to handle the "no arguments"
case sanely (show everything, instead of showing garbage) and
not listing the blocksize in hex kbytes (duh).

NAND support for DaVinci-family drivers, with HW ECC support.
Declare the NAND chip on the DM355 EVM board.
Currently tested on DM355 for Linux interop using the standard
large page (2KB) chip in the EVM socket; "hwecc1" and "hwecc4"
work fine. (Using hwecc4 relies on patches that haven't quite
made it through the Linux-MTD bottlenecks yet.)
Not yet tested: 1-bit on small-page (although it's hard to see
how that could fail); 4-bit on small page (picky layout issues);
the "hwecc_infix" mode (primarily for older boot ROMs; testing
there is blocked on having new bootloader code).

Add a "NAND Commands" section to to the TEXI docs, covering the basic
commands except for those previously discussed as being due for removal
("nand copy") or switching to use byte offsets not block numbers.
This uses the "@deffn..." syntax for defining commands, as somewhat
suggested by the TEXI documentation, and adds a new "Command Index".
We might prefer to merge those indexes for the near term, but I think
the "@deffn" approch is probably worth switching to.
Updates a few other bits to clarify that "flash" doesn't just mean NOR.
And to fix one niggling falsity: the "reset-init" event *is* used, and
in fact it's quite important.
