* David Brownell <david-b@pacbell.net>:zwelch2009-06-163-7/+11
| | | | | | | | | | | | 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
* David Brownell <david-b@pacbell.net>:zwelch2009-06-162-6/+14
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | 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
* David Brownell <david-b@pacbell.net>:zwelch2009-06-121-0/+6
| | | | | | | | | | | | | 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

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