* 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

* When setting up an ETM, cache its ETM_CONFIG register. Thendbrownell2009-09-232-51/+178
| | | | | | | | | | | | | | | | | | | | | | | | | only expose the registers which are actually present. They could be missing for two basic reasons: - This version might not support them at all; e.g. ETMv1.1 doesn't have some control/status registers. (My sample of ARM9 boards shows all with ETMv1.3 support, FWIW.) - The configuration on this chip may not populate as many registers as possible; e.g. only two data value comparators instead of eight. Includes a bugfix in the "etm info" command: only one of the two registers is missing on older silicon, so show the first one before bailing. Update ETM usage docs to explain that those registers need to be written to configure what is traced, and that some ETM configs are not yet handled. Also, give some examples of the kinds of constrained trace which could be arranged. git-svn-id: svn://svn.berlios.de/openocd/trunk@2752 b42882b7-edfa-0310-969c-e2dbd0fdcd60

ETM registers which don't even exist there ... - Integrate the various tables to get one struct per register - Get rid of needless per-register dynamic allocation - Double check list of registers: * Remove sixteen (!) non-registers for data comparators * Remove four registers that imply newer ETM than we support * Change some names to match current architecture specs - Handle more register info * some are write-only * some are read-only * record which versions have them, just in case - Reorganize the registers to facilitate removing the extras * group e.g. comparator/counter #N registers together * add and use lookup-by-ID git-svn-id: svn://svn.berlios.de/openocd/trunk@2751 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* Initial ETM cleanups. Most of these are cosmetic:dbrownell2009-09-232-83/+113
| | | | | | | | | | | | | | | | - Add a header comment - Line up the ETM context struct, pack it a bit - Remove unused context_id (this doesn't support ETMv2 yet) - Make most functions static - Remove unused string table and other needless lines of code - Correct "tracemode" helptext Also provide and use an etm_reg_lookup() to find entries in the ETM register cache. This will help cope with corrected contents of that cache, which doesn't include entires for non-existent registers. git-svn-id: svn://svn.berlios.de/openocd/trunk@2750 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...

| | | | | | | | | | | | | | | | | | | | | | | | | | | Erase logic: - command invocation + treat "nand erase N" (no offset/length) as "erase whole chip N" + catch a few more bogus parameter cases, like length == 0 (sigh) - nand_erase() should be static - on error + say which block failed, and if it was a bad block + don't give up after the first error; try to erase the rest - on success, say which nand device was erased (name isn't unique) Device list ("nand list"): - say how many blocks there are - split summary into two lines - give example in the docs Doc tweaks: - Use @option{...} for DaVinci's supported hardware ECC options For the record, I've observed that _sometimes_ erasing bad blocks causes failure reports, and that manufacturer bad block markers aren't always erasable (even when erasing their blocks doesn't trigger an error report). git-svn-id: svn://svn.berlios.de/openocd/trunk@2724 b42882b7-edfa-0310-969c-e2dbd0fdcd60
