Fix a bug preventing ICEpick "enable that TAP" code from working: the "runtest" command wrongly finished with a JTAG reset, discarding the work the TAP enable handler just finished! Instead, JTAG should stay in RUN/IDLE state. git-svn-id: svn://svn.berlios.de/openocd/trunk@2252 b42882b7-edfa-0310-969c-e2dbd0fdcd60

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

Tighten error handling on TAP enable/disable paths a bit: - Don't enable/disable unless it's necessary. Those event handlers could have nasty side effects... - Don't *succeed* enables/disables if there was no code which could have implemented that action. This prevents bugs like wrongly acting as if the scan chain changed. - Minor whitespace cleanup in enable/disable command code. The big problem is still the lack of code to verify scan chains were actually updated as requested; this adds a comment on that. I suspect the best we can do near term will be to verify IDCODE. git-svn-id: svn://svn.berlios.de/openocd/trunk@2250 b42882b7-edfa-0310-969c-e2dbd0fdcd60

Fix bug in a warning. It warned about "huge IRlength" for an older JRC with a two bit instruction register ... wrong! git-svn-id: svn://svn.berlios.de/openocd/trunk@2249 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

Minor jtag cleanup: - remove hidden assumption about JTAG event numbering - move function declarations to a header - some end'o'line whitespace - use "calloc" not "malloc + memset" git-svn-id: svn://svn.berlios.de/openocd/trunk@2244 b42882b7-edfa-0310-969c-e2dbd0fdcd60

Currently the "debug_level 3" command tracing ignores commands that could return values to TCL scripts (by plugging in to a slightly lower level of the interpreter stack). Fix that by abstracting the tracing command and starting to make some of those previously-untraced commands use this new mechanism. git-svn-id: svn://svn.berlios.de/openocd/trunk@2224 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
