* 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

- 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
git-svn-id: svn://svn.berlios.de/openocd/trunk@439 b42882b7-edfa-0310-969c-e2dbd0fdcd60
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
git-svn-id: svn://svn.berlios.de/openocd/trunk@390 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- 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

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.
git-svn-id: svn://svn.berlios.de/openocd/trunk@364 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- bugfix in server.c
- removed unused parameter from jtag_add_ir_scan et al. This
wasn't necessary in hindsight but anyway.
- arm11 source committed but not not in Makefile.am/target.c for now.
git-svn-id: svn://svn.berlios.de/openocd/trunk@341 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- some more flash cleanup of checking halted state
- moved output handler into options.c
- very slightly tweaked server.c to make it a bit more compatible with eCos
- retired arch_state. Not quite sure how I managed to leave that out last time.

command and reduce confusion with "flash write_image".
- retired deprecated "flash erase" & "flash write".
- added flash_driver_protect/write/erase() that are wafer thin frontend
functions to low level driver functions. They implement checks
that were inconsistently handled by the drivers, e.g. check for
target halted was done in a spotty fashion.
- use return ERROR_COMMAND_SYNTAX_ERROR to print out
syntax of command instead of having lots of inlined replicas of
the command line syntax(some of which were wrong).
- use logging instead of dubious translation of error values to
human understandable explanations of why things failed.
The lower levels log the precise reason and the higher
levels can ammend context as the error propagates up
the call stack.
- simplified flash API slightly with logging instead of
allocating and returning information that the caller then
has to translate into print statements.

access by disabling "unecessary" checks.
- arm926ejs. Added missing type->mmu and type->virt2phys fn's.
for now these are used by working_area when specifying
mmu enabled and mmu not enabled address
git-svn-id: svn://svn.berlios.de/openocd/trunk@335 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added arch_state to show status of currently selected target
- simplified target->type->arch_state() api.
- clean up telnet output a bit
- fixed GDB output for arch_state
- removed a couple of unecessary exit()'s
- cleaned up error propagation a bit in a few places
git-svn-id: svn://svn.berlios.de/openocd/trunk@332 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added virtual address to working_area.
- Improved error messages in a number of places
- Added ERROR_COMMAND_SYNTAX_ERROR that commands can return to have syntax printed
- Added help for some config commands
- Added verification of sw breakpoints with ERROR() message
- Removed a couple of exit()'s and replaced with error message
- cosmetic fix to armv4_5.c, easier to read
- added polymorphic(with default) virt2phys and mmu enable query function to target.h
- added virt2phys command that uses target->type->virt2phys() fn

- now uses jtag_state_pathmove() instead of making assumptions about implementation of jtag_statemove().
- fixed a couple of bugs in timeout handling
- removed megabytes of log output when communication is failing.
- sleep is now 300ms as documented instead of 3000ms
- fixed error path of bulk write
- debug_handler can now be issued during normal operation + has help text.
Thanks Øyvind Harboe

- Faster DEBUG/INFO() when they are disabled
- target_read/write_buffer() now uses 16 and 32 bit access for single word aligned requests. Other requests are serviced as quickly as possible.
- *much* faster read/write GDB packets, removing timeout problems.
- GDB read/write packets w/single word aligned 32/16 bit access now use 32/16 bit word access.
- working area can now be changed on the fly. Provides a way to move working area about as MMU is enabled/disabled.
- cleaned up error messages for verify_image.
Thanks Øyvind Harboe
git-svn-id: svn://svn.berlios.de/openocd/trunk@302 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added target_init_reset which calls target_process_reset after all drivers have been initialised
