* NOR: add FIXMEs for writing onesDavid Brownell2010-01-081-2/+5
| | | | | | | | It can invalidate ECC codes, and in general is not guaranteed to work. (However on some chips it _appears_ to behave.) Just don't do it; don't write in those cases. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* misc ARM help/usage updatesDavid Brownell2010-01-073-7/+9
| | | | | | | | | | | | Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Uupdate some helptext to be more accurate. Don't use "&function"; functions are like arrays, their address is their name. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM966: help/usage updatesDavid Brownell2010-01-071-1/+11
| | | | | | | | | | Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Fix the User's Guide to say where the magic CP15 bits are defined; and add comments in case someone provides mcr/mrc methods. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM720: help/usage updatesDavid Brownell2010-01-071-10/+14
| | | | | | | | | | | | | Deprecate the "pass an instruction opcode" flavor of cp15 access in favor of the "arm mcr ..." and "arm mrc ..." commands, which offer fewer ways to break things. Use the same EBNF syntax in the code as for the user's guide. Update User's Guide to say where to find those magic values (which table in the ARM920 TRM).

* ARM11: help/usage updatesDavid Brownell2010-01-071-12/+17
| | | | | | | | | | | | | | | | | Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Uupdate some helptext to be more accurate. Fix the User's Guide in a few places to be more consistent (mostly to use brackets not parentheses) and to recognize that parameter may be entirely optional (in which case the command just displays output, and changes nothing). Also reference NXP, not Philips, for LPC chips. Don't use "&function"; functions are like arrays, their address is their name. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM7/ARM9: help/usage updatesDavid Brownell2010-01-071-8/+8

Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Don't use "&function"; functions are like arrays, their address is their name. Shrink some overlong lines, remove some empties. Add a couple comments about things that should change: those extra TCK cycles for MEM-AP reads are in the wrong place (that might explain some problems we've seen); the DAP command tables should be shared, not copied.

Usage syntax messages have the same EBNF as the User's Guide. In some cases, *exactly* what the user's guide shows... e.g. talking about "offset" not "address" for trace_image.

| | | | | | | | | | Starting the daemon with with just a bare "openocd" I saw: Can't find openocd.cfg That's not an error; don't treat it as if it were. There may be an error later -- like, "no interface set up" -- but let messages only report real errors, not fake ones.
* ARM: add #defines for JTAG ack codesDavid Brownell2010-01-052-6/+9
| | | | | | | | JTAG has only two possible JTAG ack codes for APACC and DPACC register reads/writes. Define them, and remove empty "else" clause in the code which now uses those codes. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: add comments re DAP assumptionsDavid Brownell2010-01-051-2/+14
| | | | | | | I think some of these assumptions are not well-founded. Related, that swjdp_transaction_endcheck() is a bit iffy. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* gdb: fix regression in gdb_port commandØyvind Harboe2010-01-051-2/+3
| | | | | | | | | | | | | | | | | | | The gdb_port command can be invoked during normal execution to report the port used for gdb, whereas it was listed as CONFIG stage only, which caused an error when excuting it to return the reported error. Also in line with the grander goal of making more commands available during all "modes" (perhaps retiring config mode), there is no particular reason to limit gdb_port to the config stage. Regression was introduced in: b3bf1d12b2fdfba1c1cbee3e1afbfbb27cbd1a26 aka v0.4.0-rc1-32-gb3bf1d1 Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

| | | | | | | | | | The command processing conversion a while back lost the "rtck" enable/disable command; restore it. NOTE that having such a command is wrong; there's a standard way to enable adaptive clocking ("speed 0"). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM: ADIv5 JTAG symbol cleanupDavid Brownell2010-01-022-35/+68
| | | | | | | | | | | | | | Rename DAP_IR_* as JTAG_DP_* since those symbols are specifically for JTAG-DP (or SWJ-DP in JTAG mode), and won't work with SWD. Define the JTAG ABORT and IDCODE instructions for completeness; add a comment about where to (someday) use ABORT. Fix messaging which assumes everything is an SWJ-DP; say "JTAG-DP" instead, it's at least more appropriate for all JTAG transports. Shrink the affected lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: dap info fix + tweaksDavid Brownell2010-01-021-8/+14
| | | | | | | | Fix: don't print the BASE address except if it's a MEM-AP; that's an unlikely error, but there's no point getting it wrong. Tweaks: comments, capitalization. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: ADIv5 export cleanupDavid Brownell2010-01-022-31/+35
| | | | | | | | | Make some private functions "static". Remove their public declarations, and what is now an obviously unused function. Shrinks this object's size (about 5% on x86_64) while making the code's scope easier to understand. Shrink the affected lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: ADIv5 symbol and comment cleanupDavid Brownell2010-01-022-29/+94
| | | | | | | | | | | Instead of magic numbers, use their AP_REG_* constants. Rename the ROM address symbol as BASE to match ARM's documentation. Comment various other symbols in the header; add some missing ones. Remove an unused struct. Add some doxygen for stuff including the DAP structure and initialization.

* streamline and document helptext mode displaysDavid Brownell2010-01-027-16/+29
| | | | | | | | | | | | | | | | | | | Most commands are usable only at runtime; so don't bother saying that, it's noise. Moreover, tokens like EXEC are cryptic. Be more clear: highlight only the commands which may (also) be used during the config stage, thus matching the docs more closely. There are - Configuration commands (per documentation) - And also some commands that valid at *any* time. Update the docs to note that "help" now shows this mode info. This also highlighted a few mistakes in command configuration, mostly commands listed as "valid at any time" which shouldn't have been. This just fixes ones I noted when sanity testing.

* Fix usage/help search for subcommands.Dean Glazeski2010-01-021-7/+34
| | | | | | | | This makes it so that the usage/help command properly uses the whole command, including subcommand, in the search for help information. This previously caused erroneous output from the usage command handler. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Add the current command to the command informationDean Glazeski2010-01-021-0/+1
| | | | | | | | | | | I wanted to make it so I can be ignorant of a commands invocation string, so I tried to use CMD_CURRENT (aka cmd->current) which is supposed to house a pointer to the current command.  It turns out that this wasn't being set. This patch adds the current command structure to the command invocation structure before sending it along to the command handler. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Fix Luminary FT2232 layout docs/configsDavid Brownell2009-12-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
