- hmm..... did I screw up? Was XScale and not gdb_server busted here?
My thinking was that OpenOCD has a canonical internal representation
of registers that match GDB's expectations
git-svn-id: svn://svn.berlios.de/openocd/trunk@484 b42882b7-edfa-0310-969c-e2dbd0fdcd60
are up and running. The examination and validation is actually
"optional" from the point of view of GDB + telnet servers.
Multiple targets should work fine with this.
- jtag_speed is dropped(divisor is increased), if jtag examination and
validation fails.
- the chain is validated 10x to catch the worst jtag_speed offences
- added LOG_SILENT that can be used to shut up log. Feeble
ersatz for try+catch.
- GDB register packets are now always replied in order to make sure
that GDB connect works. If the target is not halted, then these
packets contain dummy values.

- Fixed memory leak in gdb_server.c
- pushed "Error:" statements up into fn's that know something about what went wrong
- load_image now fails if target_write_memory() fails
- only issue an asynchronous halt() upon connect of GDB. Synchronous halt/reset
doesn't really work as what's required to initialize the target might involve a
special monitor sequence for the target in question
- syntax error handling improved(fewer exit()'s)
git-svn-id: svn://svn.berlios.de/openocd/trunk@482 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- ERROR_FAIL - added to emphasize that information about what went wrong is
contained in Error: log statements and not in a 32 bit return value.

- added new commands arm11 mrc and arm11 mcr to generate these instructions during debug
Thanks Michael Bruck

- switch to synchronous halt during connect. This fixes the bug
where poll() was not invoked between halt() and servicing the
'g' register packet
- halt() no longer returns error code when target is already halted, just
logs a warning. Only the halt() implementation can say anything
meaningful about why a halt() failed, so error messages are pushed
up to halt()
- fixed soft_reset_halt infinite loop bug in arm7_9_common.c. The rest
of the implementations are still busted.
- by using USER() instead of command_print() the log gets the
source + line #. Nice.
- no longer invoke exit() if soft_reset_halt fails. A reset can often
fix the problem.

- force simulate_reset_on_next_halt when target state is initially detected
- print out method of debug entry
- fix VCR activation (didn't work before)
git-svn-id: svn://svn.berlios.de/openocd/trunk@452 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added a check to jtag_add_pathmove() for legal path transitions
- tweaked jtag.h docs a little bit
- made some jtag bypass tests _DEBUG_JTAG_IO_
git-svn-id: svn://svn.berlios.de/openocd/trunk@448 b42882b7-edfa-0310-969c-e2dbd0fdcd60
Passes 94kBytes/s regression test.
Works with str912, which relies on bypass

uninitialized buffer issue in handle_flash_info_command in flash.c, some formatting.

* GDB remote server will now remain online even if the target
is in a funny state, e.g. if it requires a reset, it is
running while GDB is not in the continue or step packet,
e.g. via monitor resume/halt commands in GDB script.
* Added some _DEBUG_GDB_IO_ debug tools
* Fixed a couple of GDB server lockups, e.g. when O packets
detect a severed connection
* added ACK upon connection (send +).
* added keep-alive messages to reset so GDB protocol remains happy.
* fixed crash when timing out connection to GDB
git-svn-id: svn://svn.berlios.de/openocd/trunk@445 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Added simulate_reset_on_next_halt that can be extended to do all sorts
of cleanups for systems without proper reset. Right now it just writes 0
to the control register to disable caches.
- Step skips over Wait for Interrupt instruction
- fix for count
- fix for printf format errors

Small cosmetic fixes in the license header to make them all look the
same, fix some typos, update README.
git-svn-id: svn://svn.berlios.de/openocd/trunk@396 b42882b7-edfa-0310-969c-e2dbd0fdcd60
More precise, less code.
- removed unused code in fileio.c
- Windows should now find debug_handler.bin

- open_file_from_path() now uses logging feature
- open_file_from_path() no longer uses paths for anything but "r" mode. Fixes
bug waiting to happen.

arm11
--- Added burst memory transfer mode
This does not explicitly query command execution but rather uses a small
delay produced by the FT2232 on certain TAP commands.
A potential failure of this process is detected afterwards and the
program terminates with an error.
'arm11 memwrite burst disable'
can be used to switch this feature off.
'arm11 memwrite error_fatal disable'
can be used to prevent the program to exit on an memory write error
--- Added support for interrupt breaking via VCR register
Use 'arm11 vcr' command to set.
--- Cleaned up the handling of
halt/resume/step/poll, target->state, target->debug_reason,
target_call_event_callbacks() at least as far as I could guess the
intended behaviour from other targets.
Did some overall positive tests with GDB.
--- Added support for breakpoints
Hardware breakpoints only. All breakpoints will be treated as hardware
breakpoints.
All ARM11's seem to have at least 6 hardware breakpoints.
--- Stepping over BKPT added
Modification to PC without touching the target.
--- Stepping over a B or BL to self will do nothing

- fix indentation of multi-level commands
- make help command work with multi-level commands

this patch fixes an issue in jtag_init - shall not reset jtag to NULL.
This causes jtag interface (USB device) not to be closed properly if jtag chain validation fails.
Once the underlaying jtag interface is initialized, jtag pointer shall be left untouched,
even in case of an error, so that proper cleanup can be done, see exit_handler in openocd.c

provides a better impeadance match for debug output char fn's, e.g. eCos.
- Line endings are now added at the caller site of command_print*(). command_print()
still adds a line ending
- echo of commands in scripts are now available via debug_level instead of
forced echo
- Added a USER_SAMELINE() for printing without a lineend.
