2010-09-13propagate return status of set_breakpoint() up call chainMike Dunn
Hi everyone, I figured since I was poking around in the breakpoint code on other arches, I'd add this change to those arches that don't do it already. This patch propagates the return code of <arch>_set_breakpoint() up the call stack. This ensures that the higher layer breakpoint infrastructure is aware that an error ocurred, in which case the breakpoint is not recorded. Normally I wouldn't touch code that I can't test, but the code is very uniform across architectures, and the change is rather benign, so I figured after careful inspection that it is safe. If the maintainers or others think this is imprudent, the patch can be dropped. Also changed the error code to something more appropriate in two cases where hardware resources are unavailable. Comments and criticisms of course gratefully received. Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-09-12helper: add stacktrace command that returns error stacktraceØyvind Harboe
Ability to access the stacktrace from a script is quite handy. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

2010-09-11version command: make it scriptableØyvind Harboe
you can now set a variable in a script like set version [version]. Also version takes an optional argument "git" to show git version of source. If git is not installed during the build, then this will yield an error that is ignored during the build and "version git" returns an empty string.

2010-09-11command: capture command now handles both types commandsØyvind Harboe
Commands that output progress output and no return value will have the progress output captured. Commands that do not output progress output(tcl commands) will return the tcl return value instead. The advantage here is that it is no longer necessary to consider which command one is capturing, it works for either. Example #1: capture progress output: set foo [capture help] Example #2: capture tcl return value set foo [capture {set abc def}] Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-09-11cfi: random crash in cfi_probe() fixedØyvind Harboe
for non_cfi cfi chips free() was invoked on rodata. The mystery is why this bug has survived for so long. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-09-11cfi: tighten up type usage a bitØyvind Harboe
sizeof() is a bit less scary than seing assumption about size of type, no bug as such. Use NULL instead of 0 for pointers. More obvious that it is a pointer from code inspection. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-09-09xscale: mark xscale registers invalid on debug entryMike Dunn
Hi everyone, This simple patch fixes a problem I noticed on the xscale where incorrect values are sometimes reported by the reg command. The problem can occur when requesting the value of registers in the xscale-specific register cache. With a couple of exceptions, none of the registers in the xscale register cache are automatically retrieved on debug entry. This is probably fine, as they are unlikely to be needed on a regular basis during a typical debug session, and they can be retrieved when explicitly requested by name using the reg command. The problem is that once this is done, the register remains marked as valid for the remainder of the OpenOCD session, and the reg command will henceforth always report the same value because it is obtained from the cache and is never again retrieved from the debug handler on the target. The fix is to mark all registers in the xscale register cache as invalid on debug entry (before the two exceptions are retrieved), thus forcing retrieval (when requested) from the target across resumptions in execution, and avoiding the reporting of stale values. Small addition change by Øyvind: change 'i' to unsigned to fix compiler warning for xscale_debug_entry() fn.

2010-09-08Remove duplicated initializationAlexander Stein
I a mail conversation with Øyvind we stated that speed may not be set at all on case CLOCK_MODE_KHZ and CLOCK_MODE_RCLK. Also there isn't proper error propagation adapter_khz_to_speed or jtag_rclk_to_speed. So jtag_get_speed may need some rewrite for error propagation.

2010-09-03jtag: fix regression with dummy driver and when starting OpenOCD with target ↵Øyvind Harboe
powered down Do not fail startup if communication with target is not possible. OpenOCD supports launching without a target connected or the target powered down. The user will typically power up the target and issue a "reset init" + load his application after OpenOCD is started then. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-09-03Numonyx M29W160ET patchWookey
Someone called David Carne popped up on IRC and offered a fix (as he's not on this list so can;t post here). I am just passing it on. (thanx David) 10:54 < davidc__> Basically; the Numonyx M29W160ET has an incorrect CFI PRI block; it describes the erase blocks backwards 10:54 < davidc__> the linked patch has a fixup for that part [really trivial]:
2010-08-31cortex m3: add cortex_m3 reset_config cmdSpencer Oliver
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>

2010-08-15avr32: work-in-progressOleksandr Tymoshenko
committed so as to ease cooperation and to let it be improved over time. So far it supports: - halt/resume - registers inspection - memory inspection/modification I'm still getting up to speed with OpenOCD internals and AVR32 so code is a little bit messy and I'd appreciate any feedback.

2010-08-12str9x: faster flash erase of entire chipFredrik Hederstierna
The patch improves flash erase for STR9x in case of a full bank erase. Then the chip erase command is used instead which improves speed significantly. Also I think it might help if e.g. STR912 enters some state where flash banks are locked, and a chip erase command is the key for unlocking the flash.

2010-08-09arm7/9: fix "reset run + halt"Øyvind Harboe
if polling is off, then "reset run + halt" would fail since halt incorrectly assumed the target was in the reset state as it is the internal poll implementation that moves the sw tracking of the target state out of the reset state. To reproduce: > reset run; halt JTAG tap: zy1000.cpu tap/device found: 0x1f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x1) BUG: arm7/9 does not support halt during reset.
