* Add a new JTAG "setup" event; use for better DaVinci ICEpick support.dbrownell2009-10-051-6/+22
| | | | | | | | | | | | | | | | | 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 git-svn-id: svn://svn.berlios.de/openocd/trunk@2800 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* Minor ETB and ETM bugfixes and doc updatesdbrownell2009-10-021-5/+29
| | | | | | | | | | | | | | | | | | | | | - ETB * report _actual_ hardware status, not just expected status * 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. git-svn-id: svn://svn.berlios.de/openocd/trunk@2790 b42882b7-edfa-0310-969c-e2dbd0fdcd60

* Streamline Capture-IR handling and integrity test.dbrownell2009-09-261-10/+12
| | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn://svn.berlios.de/openocd/trunk@2758 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* When setting up an ETM, cache its ETM_CONFIG register. Thendbrownell2009-09-231-2/+38
| | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn://svn.berlios.de/openocd/trunk@2752 b42882b7-edfa-0310-969c-e2dbd0fdcd60

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.

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

| | | | | | | | | | | | 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
