2009-11-13presto_t -> struct prestoZachary T Welch
Remove useless typedef.
2009-11-13ft2232_device_t -> struct ft2232_deviceZachary T Welch
Remove misleading typedef from ft2232_device; it was barely used.
2009-11-13jlink_jtag_t -> struct jlinkZachary T Welch
Remove misleading typedef and redundant suffix.
2009-11-13cable_t -> struct cableZachary T Welch
Remove useless typedef and redundant suffix from parport struct cable.
2009-11-13pending_scan_result_t -> struct pending_scan_resultZachary T Welch
Remove misleading typedef from struct struct pending_scan_result. Future patches need to remove these duplicated types and code.
2009-11-13armjtagew_jtag_t -> struct armjtagewZachary T Welch
Remove useless typedef and redundant suffix from struct armjtatew_jtag.
2009-11-13use struct jtag_tap_event_actionZachary T Welch
Remove useless typedef and redundant suffix from jtag_tap_event_action.
2009-11-13jtag_event_callback_t -> struct jtag_event_callbackZachary T Welch
Remove useless typedef and redundant suffix from jtag_event_callback. Add documentation for the structure.
2009-11-13jtag_interface_t -> struct jtag_interfaceZachary T Welch
Remove useless typedef and redundant suffix from struct jtag_interface.
2009-11-13bitbang_interface_t -> struct bitbang_interfaceZachary T Welch
Removes another useless typedef and suffix.
2009-11-13bitq_interface_t -> struct biq_interfaceZachary T Welch
Remove useless typedef and redundant suffix.
2009-11-13encapsulate bitq_state structureZachary T Welch
Move the bitq_state structure from the header to source file, as it is used internally. Also removes its silly typedef.
2009-11-13scan_field_t -> struct scan_fieldZachary T Welch
Remove useless structure typedef.
2009-11-13jtag_tap_t -> struct jtag_tapZachary T Welch
Search and destroy the jtag_tap_t typedef. This also cleans up a layering violation, removing the declaration from types.h.
2009-11-13command_handler_t: make argc unsignedZachary T Welch
The number of command arguments will always be 0 or more, so use the right type in handlers. This has a cascading effect up through the layers, but the new COMMAND_HANDLER macros prevented total chaos.
2009-11-13add CMD_NAME macro for command handlersZachary T Welch
By introducing the CMD_NAME macro, this parameter may be integrated as args[-1] in command.[ch], without touching any other call sites.
2009-11-13use CALL_COMMAND_HANDLER instead of direct callsZachary T Welch
By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or even removed in inherited signatures, without requiring revisiting all of the various call sites.
2009-11-13use COMMAND_HELPER for command helper functionsZachary T Welch
Define the numerous helpers that inherit command handler parameters using the COMMAND_HELPER macro.
2009-11-13use COMMAND_HANDLER macro to define all commandsZachary T Welch
2009-11-12parport: add support for the jtag_khz command.Jonas Horberg
Add the khz and speed_div functions to the parport interface driver. Add the parport_toggling_time function that tells the parport driver how long (in nanoseconds) it takes for the hardware to toggle TCK. [dbrownell@users.sourceforge.net: tweak doc for clarity, mention multimeter, and whitespace fixes] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-11fix 'jtag interface' behaviorZachary T Welch
Without this patch, running "openocd -c 'jtag interface'" segfaults. Now, it returns the string "undefined" when the interface is unset.
2009-11-09jtag: remove useless declarationsZachary T Welch
Contrary to my previous assessment, some opportunities to remove forward declarations were overlooked. Remove them by moving the definitions of the command registration and interface structure to the end of files.
2009-11-09finish removing deprecated/obsolete commandsDavid Brownell
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 ...

2009-11-09src/jtag: remove 'extern' and wrap headers.Zachary T Welch
Removes the 'extern' keyword from function declarations. Wraps long prototypes to fit into 80 columns. Fixes documentation for jtag_tap_s::{,has}idcode fields.

2009-10-27Signalyzer: H2 and H4 supportOleg Seiljus
This patch includes partial support for these new JTAG adapters. More complete support will require updates to the libftdi code, for EEPROM access. [dbrownell@users.sourceforge.net: fix whitespace, linelen, etc ] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-26ft2232: less noise with _DEBUG_JTAG_IO_David Brownell
Don't log "Yes, I'm *still* in TAP_IDLE" every seven runtest clocks.

2009-10-26JTAG: simple autoprobingDavid Brownell
This patch adds basic autoprobing support for the JTAG scan chains which cooperate. To use, you can invoke OpenOCD with just: - interface spec: "-f interface/...cfg" - possibly with "-c 'reset_config ...'" for SRST/TRST - possibly with "-c 'jtag_khz ...'" for the JTAG clock Then set up config files matching the reported TAPs. It doesn't declare targets ... just TAPs. So facilities above the JTAG and SVF/XSVF levels won't be available without a real config; this is almost purely a way to generate diagnostics. Autoprobe was successful with most boards I tested, except ones incorporating C55x DSPs (which don't cooperate with this scheme for IR length autodetection). Here's what one multi-TAP chip reported, with the "Warn:" prefixes removed: clock speed 500 kHz There are no enabled taps. AUTO PROBING MIGHT NOT WORK!! AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x2b900f0f ..." AUTO auto1.tap - use "jtag newtap auto1 tap -expected-id 0x07926001 ..." AUTO auto2.tap - use "jtag newtap auto2 tap -expected-id 0x0b73b02f ..." AUTO auto0.tap - use "... -irlen 4" AUTO auto1.tap - use "... -irlen 4" AUTO auto2.tap - use "... -irlen 6" no gdb ports allocated as no target has been specified The patch tweaks IR setup a bit, so we can represent TAPs with undeclared IR length.

2009-10-25JTAG: jtag_tap_init() bugfixesDavid Brownell
Stop allocating three bytes per IR bit, and cope somewhat better with IR lengths over 32 bits. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-23jtag: clean up TAP state name handlingDavid Brownell
Some cosmetic cleanup, and switch to a single table mapping between state names and symbols (vs two routines which only share that state with difficulty). Get rid of TAP_NUM_STATES, and some related knowledge about how TAP numbers are assigned. Later on, this will help us get rid of more such hardwired knowlege. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-23SVF: clean up, mostly for TAP state name handlingDavid Brownell
- Use the name mappings all the other code uses: + name-to-state ... needed to add one special case + state-to-name - Improve various diagnostics: + don't complain about a "valid" state when the issue is actually that it must be "stable" + say which command was affected - Misc: + make more private data and code be static + use public DIM() not private dimof() + shorten the affected lines Re the mappings, this means we're more generous in inputs we accept, since case won't matter. Also our output diagnostics will be a smidgeon more informative, saying "RUN/IDLE" not just "IDLE" (emphasizing that there can be side effects). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-20XSVF: use svf_add_statemove()David Brownell
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.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-08prevent abort via polling during jtag_resetDavid Brownell
Observed: openocd: core.c:318: jtag_checks: Assertion `jtag_trst == 0' failed. The issue was that nothing disabled background polling during calls from the TCL shell to "jtag_reset 1 1". Fix by moving the existing poll-disable mechanism to the JTAG layer where it belongs, and then augmenting it to always pay attention to TRST and SRST. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-08Stop ignoring most scan chain validation errorsDavid Brownell
Among other things this causes startup errors to kick in the fallback "reset harder" logic during server startup. Comments are also updated a bit, explaining what the various error paths signify (in at least my observation). There's one class of validation error that we can still plausibly ignore: when wrong IDCODE values are observed. This change seems to have helped make an OMAP5912 behave much more reliably. There's still some post-reset flakiness, but it's unrelated to scan verification. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-07Force sane SRST and TRST initializationdbrownell
At least some FT2232 based adapters don't necessarily come up in the expected state, with SRST and TRST disabled. Since other adapters could suffer the same problem, let's avoid needing to patch every driver and just force *all* adapters to initialize those values properly at server startup. git-svn-id: svn://svn.berlios.de/openocd/trunk@2824 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-10-07Better fix for TAPs violating the JTAG spec for IR-Capture.dbrownell
Instead of just assuming all IDCODE-deprived TAPs violate the JTAG spec (they don't!), just require TAPs with such problems to be declared with proper ircapture/irmask values. Example, with mask and value of zero. git-svn-id: svn://svn.berlios.de/openocd/trunk@2823 b42882b7-edfa-0310-969c-e2dbd0fdcd60
