* pipes: add documentation for pipesØyvind Harboe2010-10-011-5/+22
| | | | | | | | | Stick with the name "gdb_port" even if this command can be used for other things(disable, named pipes, anonymous stdin/out pipe). "port" is correct for probably more than 90% of use cases, if not more. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* xscale: some wp detail added to user manualMike Dunn2010-09-201-0/+9
| | | | | | | | | | | | | | | | Hi everyone (again), Watchpoints on xscale are quirky, so I thought a little explanation in the user's manual was warranted. Comments gratefully received. Last one, Øyvind :-) Thanks, Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
* cortex m3: add cortex_m3 reset_config cmdSpencer Oliver2010-08-311-0/+15
| | | | | | | | | | | | This new cmd adds the ability to choose the Cortex-M3 reset method used. It defaults to using SRST for reset if available otherwise it falls back to using NVIC VECTRESET. This is known to work on all cores. Move any luminary specific reset handling to the stellaris cfg file. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

* tcl: remove silly ocd_ prefix to array2mem and mem2arrayØyvind Harboe2010-08-111-2/+2
| | | | | | | | ocd_ prefix is used internally in OpenOCD as a kludge more or less to deal with the two kinds of commands that OpenOCD has. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* xscale documentation: vector table handlingMike Dunn2010-08-021-4/+22
| | | | | | | | | | | | | | | | | | | | | | | Hi everyone. I noticed some incorrect information in the user manual regarding how the vector table is handled on the xscale, so for your consideration, here's a short patch that corrects it, and adds a little more detail I thought might be helpful. The documentation states that OpenOCD does not attempt to synchronize the vector tables in memory with those stored in the "mini instruction cache". In fact, on each resume it does copy from memory to the cache all entries in the high and low tables that were not previously defined using the 'xscale vector_table' command. (In src/target/xscale.c, see xscale_update_vectors(), which is invoked by xscale_resume().) I take advantage of this during Linux boot-up. The extra detail describes in general terms how I do this. Corrections, comments are of course gratefully received. Thanks, Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com>

* initial "transport" frameworkDavid Brownell2010-07-021-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the guts of a transport framework with initialization, which should work with current JTAG-only configurations (tested with FT2232). Each debug adapter can declare the transports it supports, and exactly one transport is initialized. (with its commands) in any given OpenOCD session. * Define a new "struct transport with init hooks and a few "transport" subcommands to support it: "list" ... list the transports configured (just "jtag" for now) "select" ... makes the debug session use that transport "init" ... initializes the selected transport (internal) * "interface_transports" ... declares transports the current interface can support. (Some will do this from C code instead, when there are no hardware versioning (or other) issues to prevent it. Plus some FT2232 tweaks, including a few to streamline upcoming support for an SWD transport (initially for Luminary adapters). Eventually src/jtag should probably become src/transport, moving jtag-specific stuff to transport/jtag. Signed-off-by: David Brownell <db@helium.(none)>
* flash: add virtual flash bank driverSpencer Oliver2010-05-261-0/+20
| | | | | | | | | | | | | This adds a virtual flash bank driver that allows virtual banks to be defined that refer to an existing flash bank. For example the real address for bank0 on the pic32 is 0x1fc00000 but the user program will either be in kseg0 (0xbfc00000) or kseg1 (0x9fc00000). This also means that gdb will be aware of all the read only flash addresses. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

* 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).

* 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).

* 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.

* User's Guide mentions OS-specific installationDavid Brownell2010-02-211-0/+12

* 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>

* 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.)
