* Documentation: consistency in GDB command nameMarc Pignat2010-05-111-1/+1
| | | | Always use the complete name of the GDB command, not an abbreviation.
* Documentation : arm920t implements armv4Marc Pignat2010-05-111-1/+1
| | | | There is a small typo in the cpu list, arm920t is armv4.
* flash: stop caching protection stateØyvind Harboe2010-05-051-11/+2
| | | | | | | | | | | | | | There are a million reasons why cached protection state might be stale: power cycling of target, reset, code executing on the target, etc. The "flash protect_check" command is now gone. This is *always* executed when running a "flash info". As a bonus for more a more robust approach, lots of code could be deleted. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* jtag/tcl.c cleanup -- split out "adapter.c"David Brownell2010-03-271-3/+3
| | | | | | | | | | | | Clean up the jtag/tcl.c file, which was one of the biggest and messiest ones in that directory. Do it by splitting out all the generic adapter commands to a separate "adapter.c" file (leaving the "tcl.c" file holding only JTAG utilities). Also rename the little-used "jtag interface" to "adapter_name", which should have been at least re-categorized earlier (it's not jtag-only).

| | | | | | | | | | | The mips_m4k_assert_reset has now been restructured so the variant ejtag_srst is not required anymore. The ejtag software reset will be used if the target does not have srst connected. Remove ejtag_srst from docs. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* rename jtag_nsrst_assert_width as adapter_nsrst_assert_widthDavid Brownell2010-03-151-1/+1
| | | | | | | | | | | Globally rename "jtag_nsrst_assert_width" as "adapter_nsrst_assert_width", and move it out of the "jtag" command group ... it needs to be used with non-JTAG transports Includes a migration aid (in jtag/startup.tcl) so that old user scripts won't break.

* Add support for Bus Pirate as a JTAG adapter.Michal Demin2010-03-111-0/+3
| | | | | | | | This includes a driver and matching config file. This support needs to be enabled through the initial "configure" (use "--enable-buspirate"). Signed-off-by: Michal Demin <michaldemin@gmail.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* split "interface" commands from "jtag" onesDavid Brownell2010-03-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | We'll need to be able to work with debug adapter interfaces (drivers) even when they're not used for JTAG ... for example, while there are multi-transport drivers which support JTAG *and* several other transports (or just one more, like SWD) there are also adapters with more limited goals (and no JTAG support at all). Start decoupling the two concepts ("debug adapter driver", "jtag") by having two command groups, which initialize separately. This will help us support OpenOCD sessions using only non-JTAG transports, in which JTAG commands should not be registered. Update docs to mention that the JTAG, SVF, and XSVF commands won't work without a JTAG transport. Note that at least commands working with SRST are still inappropriately coupled to JTAG ... inappropriate because (a) SRST is not part of the JTAG standard, for all that many platforms (like ARM) expect it; and also (b) because they're used with non-JTAG debug and programming interfaces, too. They should perhaps become generic "interface" operations at some point. (Similarly with the clock rate to be used by a given adapter.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* doc: not all debug adapters are "dongles"David Brownell2010-03-051-36/+98
| | | | | | | | | | | | | | | | | Talk more about "debug adapters" instead of only "dongles". Not all adapters are discrete widgets; some are integrated onto boards. If we only talk about "dongles" we rule out many valid setups, and help confuse some users (who may be using Dongle-free environments). Also start bringing out the point that JTAG isn't the only transport protocol, even though OpenOCD historically presumes "all is JTAG". (Not all debug adapters are JTAG adapters, or JTAG-only adapters.) Plus a few minor fixes (spelling etc) in the vicinity of those changes, and updates about FT2232H clocking issues (they can go faster than the older chips, and can support adaptive clocking).

Additional features are: - inverted-F pcb antenna - 36 GPIO brought out to 0.1" pin header (includes all peripheral pins) - Reset button - Two push buttons (on kbi1-5 and kbi0-4) - USB-A connector, powered from USB - up to 16V external input - pads for optional buck inductor - pads for optional 32.768kHz crystal - 2x LEDS on TX_ON and RX_ON [ dbrownell@users.sourceforge.net: shrink lines; texi ] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* new "stellaris recover" commandDavid Brownell2010-02-271-0/+15
| | | | | | | | | | | | | | | Stellaris chips have a procedure for restoring the chip to what's effectively the "as-manufactured" state, with all the non-volatile memory erased. That includes all flash memory, plus things like the flash protection bits and various control words which can for example disable debugger access. clearly, this can be useful during development. Luminary/TI provides an MS-Windows utility to perform this procedure along with its Stellaris developer kits. Now OpenOCD users will no longer need to use that MS-Windows utility. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* User's Guide mentions OS-specific installationDavid Brownell2010-02-211-0/+12
| | | | | | | | | | Specifically the Linux issue of needing "udev" rules, and MS-Windows needing driver configuration. Also, update the existing udev note to use the correct name of that rules file in the source tree. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* User's Guide: "#" in filesystems names is badDavid Brownell2010-02-101-6/+14
| | | | | | | | Sometimes MS-Windows users try to use filesystem names which include the "#" character. That's generally unwise, since it begins Tcl comments. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* User's Guide: clarify jtag_rclk adviceDavid Brownell2010-02-101-2/+4
| | | | | | | | | | Not all cores and boards support adaptive clocking, so qualify all advice to use it to depend on core and board support. It's primarily ARM cores which support this; and many of the newer ones (like Cortex-M series) don't. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* NOR: User's Guide updatesDavid Brownell2010-02-021-6/+5
| | | | | | | | | | | | Remove long-obsolete text about "erase_check" affecting "flash info" output. Move parts of that text to "protect_check", where it's still relevant; and update the "flash info" description to mention the issue. (This is still awkward. It might be best to make "protect_check" mirror "erase_check" by dumping what it finds, so "flash info" doesn't dump any potentially-stale cache info.)

* doc clarifications for server flagsDavid Brownell2010-01-281-3/+4
| | | | | | | | | | | | | | | | | | The "-f" is a shortcut for "-c" ... and providing any "-c" options means the "openocd.cfg" file isn't implicitly used. Both the User's Guide and the manual page were weak on these points, which has led to some confusion. Also update the manual page to include highlights of the search path mechanism, including the facts that it exists and that "-s" adds to it. Stop saying only the current directory is involved; the OpenOCD script library is quite significant. (Missing: complete manpage coverage of the search path, including a FILES section listing all components and saying where the script library is found.)

* User's Guide secton on target hardware setupDavid Brownell2010-01-211-1/+81
| | | | | | | | | | | Highlight the needs to properly jumper development boards; to make the OpenOCD configuration match the jumpering; and to have a usable "reset-init" method when debugging early boot code. Specific mention of the "ATX Mode" that seems useful on many i.MX boards, forcing NAND boot. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* User's guide: mention lpc2000 checksum issueDavid Brownell2010-01-201-4/+10

* NOR: add optional "flash erase_address" sector paddingDavid Brownell2010-01-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a NOR flash mechanism where erase_address ranges can be padded out to sector boundaries, triggering a diagnostic: > flash erase_address 0x0001f980 16 address range 0x0001f980 .. 0x0001f98f is not sector-aligned Command handler execution failed in procedure 'flash' called at file "command.c", line 647 called at file "command.c", line 361 > > flash erase_address pad 0x0001f980 16 Adding extra erase range, 0x0001f800 to 0x0001f97f Adding extra erase range, 0x0001f990 to 0x0001fbff erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s) > This addresses what would otherwise be something of a functional regression. An earlier version of the interface had a dangerous problem: it would silently erase data outside the range it was told to erase. Fixing that bug turned up some folk who relied on that unsafe behavior. (The classic problem with interface bugs!) Now they can get that behavior again. If they really need it, just specify "pad".

* parport (mostly) doc fixesDavid Brownell2010-01-091-13/+19
| | | | | | | | | | | | | | | | | | | The "parport_port" commands generally don't *require* a port_number; they're of the "apply any parameter, then print result" variety. Update the User's Guide accordingly. Some of those commands are intended to be write-once: parport_port, and parport_cable. Say so. Use proper EBNF for the parport_write_on_exit parameter. Parport address 0xc8b8 is evidently mutant. Say so in the "parport.cfg" file, to avoid breaking anyone with that mutant config. But update the User's Guide to include a sane example for the LP2 port. Finally document the "presto_serial" command. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
