* 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>

| | | | | | | | | | | | 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 Brownell2010-03-052-40/+102
| | | | | | | | | | | | | | | | | 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.
