2009-08-25David Brownell <david-b@pacbell.net> More jtag_add_reset() cleanup:oharboe
Unify the handling of the req_srst parameter, and rip out a large NOP branch and its associated FIXME. (There didn't seem to be anything that needs fixing; but that was unclear since the constraints were scattered all over the place not unified.) git-svn-id: svn://svn.berlios.de/openocd/trunk@2623 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-08-25David Brownell <david-b@pacbell.net> More jtag_add_reset() cleanup:oharboe
Unify the handling of the req_tlr_or_trst parameter. Basically, JTAG TMS+TCK ops ("TLR") is always used ... unless TRST is a safe option in this system configuration. git-svn-id: svn://svn.berlios.de/openocd/trunk@2622 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-08-25David Brownell <david-b@pacbell.net> Some jtag_add_reset() cleanup:oharboe
- Track whether TRST and/or SRST actually change: * If they're not changing, don't ask the JTAG adapter to do anything! (JTAG TCK/TMS ops might still be used to enter TAP_RESET though.) * Don't change their recorded values until after the adapter says it did so ... so fault paths can't leave corrupt state. * Detect and report jtag_execute_queue() failure mode * Only emit messages saying what really changed; this includes adding an omitted "deasserted TRST" message. * Only apply delays after deasserting SRST/TRST if we *DID* deassert! - Messages say "TLR" not "RESET", to be less confusing; there are many kinds of reset. (Though "TLR" isn't quite ideal either, since it's the name of the TAP state being entered by TMS+TCK or TRST; it's at least non-ambiguous in context.) So the main effect is to do only the work this routine was told to do; and to have debug messaging make more sense. git-svn-id: svn://svn.berlios.de/openocd/trunk@2621 b42882b7-edfa-0310-969c-e2dbd0fdcd60

2009-06-29David Brownell <david-b@pacbell.net>:zwelch
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

2009-06-16David Brownell <david-b@pacbell.net>:zwelch
Extend the internal JTAG event handlers to cover enable/disable, and use those events to make sure that targets get "examined" if they were disabled when the scan chain was first set up: - Remove "enum jtag_tap_event", merge with "enum jtag_event", so C code can now listen for TAP enable/disable events. - Report those events so they can trigger callbacks. - During startup, make target_examine() register a handler to catch ENABLE events for any then-disabled targets. This fixes bugs like "can't halt target after enabling its TAP". One class of unresolved bugs: if the target has an ETM hooked up to an ETB, nothing activates the ETB. But starting up the ETM without access to the ETB registers fails... git-svn-id: svn://svn.berlios.de/openocd/trunk@2251 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-06-16David Brownell <david-b@pacbell.net>:zwelch
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
2009-06-16David Brownell <david-b@pacbell.net>:zwelch
Fix a memory leak in jtag_tap_free(): unregister the event callback too. Also fix the associated conceptual bug in unregistering JTAG event callbacks: since the same callback procedure is used many times with different callback data (a TAP handle), that data must be considered when unregistering any callback. This could fix some crashes after TAP registration errors, by making sure the reset event handler doesn't scribble over memory that's now used by something else. git-svn-id: svn://svn.berlios.de/openocd/trunk@2245 b42882b7-edfa-0310-969c-e2dbd0fdcd60

2009-06-12David Brownell <david-b@pacbell.net>:zwelch
Partial fix to the "long IR length" problems. - Current code could handle up to 32 bit IR lengths with full functionality, if it didn't just reject may of them out of hand. So only reject clear errors, where the IR mask (or capture instruction) needs more than IrLen bits. - Longer IR lengths can only be handled in BYPASS mode for now. Example: TI's DSPs use 38-bit IR lengths. So we can't issue their IDCODE instructions... A more complete fix would be able to issue longer instructions; or minimally, would fail cleanly for the non-BYPASS case. Note that this *could* make some currently broken scripts fail, since the previous code accepted garbage values so long as they didn't use more than 16 bits. git-svn-id: svn://svn.berlios.de/openocd/trunk@2222 b42882b7-edfa-0310-969c-e2dbd0fdcd60
