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.
Sanity checked against "objdump -d" output; a bunch of the new
instructions checked out fine.

no longer explicitly specify it.

Add some text to introduce the project to new users.
Move packaging, configuration, and compilation of OpenOCD out of
the User's Guide and into README, where it can be used by users
before configuring and compiling the documentation.
Improve notes about required Subversion repository build steps.
Add reference to the standard GNU INSTALL file.

This patch adds support for the Luminary Micro LM3S9B90 target and
LM3S9B92 Evaluation Kit. These kits include a new ft2232 adapter, the
Luminary In-Circuit Debug Interface (ICDI) Board, so this is added as a
new ft2232 layout called "luminary_icdi".
git-svn-id: svn://svn.berlios.de/openocd/trunk@2429 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2428 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2415 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Minor fixup to the User's Guide, primarily related to the
handful of commands defined in "startup.tcl"; "help" was
not previously documented.
Also, be more consistent about "Config Command" definitions
(and to be explicit about that doc convention).
git-svn-id: svn://svn.berlios.de/openocd/trunk@2414 b42882b7-edfa-0310-969c-e2dbd0fdcd60
and some formatting issues with sam7 and stm32 keyword params.
Tweak at91sam3 docs. Remove ninth nibble from flash bank addresses,
clarify "at91sam3 show" variants and that the flash bank layout is
not needed as a parameter (unlike with sam7); formatting fixes.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2400 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Move the short chapter about JIM-Tcl earlier, so that we
can reasonably assume it's been introduced before we start
presenting things that presume such an introduction.
Plus a few minor typo-level fixes.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2355 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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
Plus some other updates, like adding my copyright (now that I've
basically rewritten much of this).
git-svn-id: svn://svn.berlios.de/openocd/trunk@2354 b42882b7-edfa-0310-969c-e2dbd0fdcd60
This is minimal patch to support FA526 ARMv4 compatible core.
Since it is very similar to ARM920T I tried to reuse as much
code as possible.
CPU and board configs will follow soon.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2292 b42882b7-edfa-0310-969c-e2dbd0fdcd60
The PLD stuff hasn't been documented yet. It's just Virtex2 for now,
but it looks like adding others would be easy.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2273 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Various bits of cleanup, mostly to match the style hints
I just got around to writing up.
- Various @cindex improvements
- Cross reference the command line options in a few spots,
notably for @command{debug_level}
- 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
Plus two minor bits of cleanup: remove most date references,
and refer to the reader as "you" not "the user".
git-svn-id: svn://svn.berlios.de/openocd/trunk@2271 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Distributing FTDI's "ftd2xx" library with OpenOCD violates the
OpenOCD license (GNU GPLv2 with no exceptions).
Make that clear where that build option is presented, and don't
describe the FTDI libraries as an option for any packager. (It's
fine for personal use, of course.)
Plus some related clarifications: libftdi version 0.16 for the
new FT2232H chips (for RTCK and high speed USB); the Amontec
drivers are just ftd2xx variants.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2248 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2246 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2178 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- 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
git-svn-id: svn://svn.berlios.de/openocd/trunk@2107 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Clarify docs for the evb_lm3s811 layout: works in
two modes, not just one.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2099 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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;
add the missing part_id command.
Convert the mflash support 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
- 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
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.
