* NEWS updatesDavid Brownell2010-01-221-11/+15
| | | | | | | | | | Summarize most ARM11 and Cortex-A8 updates as "acting much more like other ARMs", and mention code sharing. Clarify a few other points, including support for "reset-assert" on all ARMs except Cortex-M (which doesn't exactly need it). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* NOR: add optional "flash erase_address" sector paddingDavid Brownell2010-01-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a NOR flash mechanism where erase_address ranges can be padded out to sector boundaries, triggering a diagnostic: > flash erase_address 0x0001f980 16 address range 0x0001f980 .. 0x0001f98f is not sector-aligned Command handler execution failed in procedure 'flash' called at file "command.c", line 647 called at file "command.c", line 361 > > flash erase_address pad 0x0001f980 16 Adding extra erase range, 0x0001f800 to 0x0001f97f Adding extra erase range, 0x0001f990 to 0x0001fbff erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s) > This addresses what would otherwise be something of a functional regression. An earlier version of the interface had a dangerous problem: it would silently erase data outside the range it was told to erase. Fixing that bug turned up some folk who relied on that unsafe behavior. (The classic problem with interface bugs!) Now they can get that behavior again. If they really need it, just specify "pad".

* Cortex-M3: improved core exception handlingDavid Brownell2010-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | This updates three aspects of debugger/exception interactions: - Save the user's "vector_catch" setting, and restore it after reset. Previously, it was obliterated (rather annoyingly) each time. - Don't catch BusFault and HardFault exceptions unless the user says to do so. Target firmware may need to handle them. - Don't modify SHCSR to prevent escalating BusFault to HardFault. Target firmware may expect to handle it as a HardFault. Those simplifications fix several bugs. In one annoying case, OpenOCD would cause the target to lock up on ome faults which triggered after the debugger disconnected. NOTE: a known remaining issue is that OpenOCD can still leave DEMCR set after an otherwise-clean OpenOCD shutdown. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Coexist with quilt: rename PATCHES --> PATCHES.txtDavid Brownell2010-01-081-1/+4
| | | | | | | | | | The issues is on Win32, which ignores case in filesystem and thus doesn't tolerate the quilt "patches" directory. Rename, and add "patches" to .gitignore so that developers can choose to use quilt for local patch management. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Fix Luminary FT2232 layout docs/configsDavid Brownell2009-12-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ETM: add "etm trigger_debug" commandDavid Brownell2009-12-191-0/+1
| | | | | | | | | | | | | | | | In conjunction with manual register setup, this lets the ETM trigger cause entry to debug state. It should make it easier to test and bugfix the ETM code, by enabling non-trace usage and isolating bugs specific to thef ETM support. (One current issue being that trace data collection using the ETB doesn't yet behave.) For example, many ARM9 cores with an ETM should be able to implement four more (simple) breakpoints and two more (simple) watchpoints than the EmbeddedICE supports. Or, they should be able to support complex breakpoints, incorporating ETM sequencer, counters, and/or subroutine entry/exit criteria int criteria used to trigger debug entry.

* ETM trigger_percent becomes an ETB commandDavid Brownell2009-12-191-0/+2
| | | | | | | | This command was misplaced; it's not generic to all traceport drivers, only the ETB supports this kind of configuration. So move it, and update the relevant documentation. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* NOR FLASH: only erase/unlock whole sectorsDavid Brownell2009-12-181-0/+2
| | | | | | | | | | | | | | | Much to my surprise, I observed a "flash erase_address ..." command erasing data which I said should not be erased. The issue turns out to be generic NOR flash code which was silently, and rather dangerously, morphing partial-sector references into unrequested whole-sector ones. This patch removes that low-level morphing. If desired, it can and should be done in higher level code. (We might need to fix some stuff in the GDB server code.)

* ARM11: basic watchpoint supportDavid Brownell2009-12-041-0/+2

* basic ARM semihosting supportNicolas Pitre2009-12-031-0/+1
| | | | | | | | | | | | | | | | | | | | Semihosting enables code running on an ARM target to use the I/O facilities on the host computer. The target application must be linked against a library that forwards operation requests by using the SVC instruction that is trapped at the Supervisor Call vector by the debugger. The "hosted" library version provided with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example. This is currently available for ARM9 processors, but any ARM variant should be able to support this with little additional work. Tested using binaries compiled with Sourcery G++ Lite 2009q1-161 and ARM RVCT 3.0.

* ARM: "armv4_5" command prefix becomes "arm"David Brownell2009-11-161-0/+2
| | | | | | | | | | Rename the "armv4_5" command prefix to straight "arm" so it makes more sense for newer cores. Add a simple compatibility script. Make sure all the commands give the same "not an ARM" diagnostic message (and fail properly) when called against non-ARM targets. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: use now-generic memory utilsDavid Brownell2009-11-151-0/+8
| | | | | | | | | | | | Now the ARM11 cores can use the renamed arm_checksum_memory() and arm_blank_check_memory() routines ... do so. Sanity checked with "flash erase_check" of both NOR banks on an OMAP2420 ... the algorithm code dumped four lines of of "poll" status after each of almost 520 blocks (yes, *very* annoying) but gave plausible results after producing that spam.

* ARM: rename "arm9tdmi vector_catch" to "arm9 ..."David Brownell2009-10-251-0/+2
| | | | | | And update doc accordingly. That EmbeddedICE register was introduced for ARM9TDMI and then carried forward into most new chips that use EmbeddedICE.
* make PXA255 targets enumerate sort-of-OKDavid Brownell2009-10-081-0/+1
| | | | | | | | | | | | | | | | | | | Startup now mostly works, except that the initial target state is "unknown" ... previously, it refused to even start. Getting that far required fixing the ircapture value (which can never have been correct!) and the default JTAG clock rate, then providing custom reset script. The "reset" command is still iffy. DCSR updates, and loading the debug handler, report numerous DR/IR capture failures. But once that's done, "poll" reports that the CPU is halted (which it shouldn't be, this was "reset run"!), due to the rather curious reason "target-not-halted". Summary: you still can't debug these parts, but it's closer. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* add overridable Tcl "init_reset"David Brownell2009-10-081-0/+1
| | | | | | | | | | | This abstracts the "jtag arp_init-reset" call into a method called from OpenOCD startup and reset processing. Platforms which have different requirements for how such hard resets must be performed can now override "init_reset" instead of needing to rebuild custom hacked versions of the server.
