* Updates for "reset_config":dbrownell2009-10-071-13/+94
| | | | | | | | | | | - revert to previous default: don't talk JTAG during SRST - add "srst_nogates" flag, the converse of "srst_gates_jtag" - with no args, display the current configuration And update the User's Guide text with bullet lists to be a bit more clear. git-svn-id: svn://svn.berlios.de/openocd/trunk@2818 b42882b7-edfa-0310-969c-e2dbd0fdcd60

* Add a new JTAG "setup" event; use for better DaVinci ICEpick support.dbrownell2009-10-051-8/+10
| | | | | | | | | | | | | | | | | 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

* Streamline Capture-IR handling and integrity test.dbrownell2009-09-261-12/+22
| | | | | | | | | | | | | | | | | | | | 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
* Debug message updates:dbrownell2009-09-201-14/+1
| | | | | | | | | | | | | | | | | | | - Shrink messaging during resets, primarily by getting rid of "nothing happened" noise that hides *useful* information. - Improve: the "no IDCODE" message by identifying which tap only supports BYPASS; and the TAP event strings. Related minor code updates: - Remove two needless tests when examining the chain: we know we have a TAP, and that all TAPs have names. - Clean up two loops, turning "while"s into "for"s which better show what's actually being done. git-svn-id: svn://svn.berlios.de/openocd/trunk@2736 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

| | | | | | | | | | | | | | | | | | | | | | | 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
* David Brownell <david-b@pacbell.net>:zwelch2009-06-161-12/+33
| | | | | | | | | | | | | | | | | | | | 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

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