* Improve jtag_validate_ircapture() diagnostics.dbrownell2009-10-051-8/+10
| | | | | | | | | | | Bugfix the error message so it shows the disliked value, and add a debug message showing each TAP's IR capture value, all N bits. This just changes diagnostics ... it still ignores the parameters given to us at TAP declaration time. git-svn-id: svn://svn.berlios.de/openocd/trunk@2801 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* Add a new JTAG "setup" event; use for better DaVinci ICEpick support.dbrownell2009-10-053-23/+43
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | - Don't issue needless JTAG resets ... only do them after errors. Normal exit now leaves every TAP in BYPASS. - Fix an unlikely memory leak on one fault path. - Remove the oddball limitation that invalid capture LSBs trigger errors only for TAPs that support IDCODE. Re the JTAG reset: there are too many of them, and they can (and do!) change system state. So the needless ones should get removed. This one was especially pointless. git-svn-id: svn://svn.berlios.de/openocd/trunk@2777 b42882b7-edfa-0310-969c-e2dbd0fdcd60

* Update FT2232 driver so that it reliably enters TAP_RESET.dbrownell2009-09-271-2/+10
| | | | | | | | | | | | | | | | When the OpenOCD server starts up it records its state as TAP_RESET, even though it could be anything. Then when it starts to examine the scan chain, it calls jtag_add_tlr() which sees it doesn't have any work to do, and so it does nothing. This can make the next operations fail because they start from the wrong TAP state... Instead of caring about the current recorded state, always enter TAP_RESET by forcing five clocks with TMS high. (NOTE: it seems most other JTAG adapter drivers have this same bug.) git-svn-id: svn://svn.berlios.de/openocd/trunk@2763 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

NOTE that there was previously some code that looked like it was trying to do this ... which didn't work, because it was looping over the list of expected TAPs, and never checked *after* that list completed! That could hide some *nasty* reset issues... Also replace a now-obsolete scanchain length test with one that behaves correctly; and update reporting of unexpected IDCODEs. git-svn-id: svn://svn.berlios.de/openocd/trunk@2739 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | - 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

| | | | | | | | | | | | | | | | | | | | | | | - 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

It can only be built with the FTD2XX driver. libftdi supports FT2232H/FT4232H since version 0.16 2. A speed value of 0 is used as a RTCK request indicator. This clashes with the valid clock division value 0 that provide the highest fixed clock frequency. 3. The ft2232_speed_div function return the maximum selectable frequency (30MHz) when RTCK is activated. It should return 0. 4. The ft2232_khz function return ERROR_OK when RTCK is requested even for devices lacking RTCK support. It should return ERROR_FAIL so the upper driver layers can detect this and try to fallback to a fixed frequency. 5. FT2232H/FT4232H have a backward compatibility function that divide the clock by 5 to get the same frequency range as FT2232D. There is no code that disable this functionality. I can not find anything about if this is enabled or disabled by default. I think it is safest to actively disable it. git-svn-id: svn://svn.berlios.de/openocd/trunk@2591 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updates to private TAP state tables in amtjtagaccel interface driver. The first change is the neccesary one to correct a long-standing bug that caused the IDCODE to be shifted by one bit too many. This was caused by an incorrect path from state RESET to state DRSHIFT. The value of those 2 bytes were 0x8a and 0x04. This means that the bitstream to do this transition is 0b 00100 01010 (send LSB first). This will bring you from the reset state to the shift state; however, you enter the shift-state twice, which explains why the ID-CODE that will be read next will be shifted 1 bit. The fix changes these to 0x05 and 0x00. This will send the bitstream 0b 00101 (send LSB first). This will bring the TAP controller from the RESET state to the DRSHIFT state directly, without entering the DRSHIFT state twice. After checking the whole table, two other transitions were found that could be optimized (5 bits in stead of 10 bits). Summary off all changes: From To Old values Old Bitstream New values New Bitstream Remarks ---- ------- ---------- ------------- ---------- ------------- ------- RESET DRSHIFT 0x8a 0x04 0b00100 01010 0x05 0x00 0b00101 1,2 IDLE DRSHIFT 0x85 0x08 0b01000 00101 0x04 0x00 0b00100 2 IDLE IRSHIFT 0x8b 0x08 0b01000 01011 0x06 0x00 0b00110 2 [1] Fixes the IDCODE bug [2] Optimization git-svn-id: svn://svn.berlios.de/openocd/trunk@2472 b42882b7-edfa-0310-969c-e2dbd0fdcd60
