ATSAM4L has a "System Manager Access Port" (SMAP) that holds the CPU
in reset if TCK is low when srst (RESET_N) is deasserted.
Without this change any use of sysresetreq or srst locks the chip
in reset state until power is cycled.
A new function smap_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and SMAP reset is released then.

This patch might influence openocd Tcl commands behaviour in subtle
ways, please give it a nice testing.
The idea is that if an OpenOCD Tcl command returns an error, an
exception is raised, and then the return code is propogated all the
way up (or to the "catch" if present). This allows to detect
"shutdown" which is not actually an error but has to raise an
exception to stop execution of the commands that follow it in the
script.
openocd_thread special-cases shutdown because it should then terminate
OpenOCD with a success error code, unless shutdown was called with an
optional "error" argument which means terminate with a non-zero exit
code.

This should allow most of the existing configurations for older
versions to remain compatible without forcing the user to change his
or her config to explicitly select transport.
Also in some circumstances can remove the need to chain a "-c transport
select X" when building custom configs on the command line, which seems
like a common new user pitfall.

There were two problems with the _protect() feature:
1. The address written was off by a factor of two because the address
register takes 16-bit rather than 8-bit addresses. As a result the
wrong sectors were (un)protected with the protect command. This has
been fixed.
2. The protection settings issued via the lock or unlock region commands
don't persist after reset. Making them persist requires modifying the
LOCK bits in the User Row using the infrastructure described below.
The Atmel SAMD2x MCUs provide a User Row (the size of which is one
page). This contains a few settings that users may wish to modify from
the debugger, especially during production. This change adds commands
to inspect and set:
- EEPROM size, the size in bytes of the emulated EEPROM region of the
Flash.
- Bootloader size, the size in bytes of the protected "boot" section of
the Flash.
This is done by a careful read-modify-write of the special User Row
page, avoiding erasing when possible and disallowing the changing of
documented reserved bits. The Atmel SAMD20 datasheet was used for bit
positions and descriptions, size tables, etc. and testing was done on a
SAMD20 Xplained Pro board.
It's technically possible to store arbitrary user data (ex: serial
numbers, MAC addresses, etc) in the remaining portion of the User Row
page (that is, beyond the first 64 bits of it). The infrastructure used
by the eeprom and bootloader commands can be used to access this as
well, and this seems safer than exposing the User Row as a normal Flash
sector that openocd understands due to the delicate nature of some of
the data stored there.

Reference code for the SAMD2x disables caching in the NVM controller when
issuing NVM commands. Let's do this as well to be consistent and safer.
Add a "chip-erase" for the Atmel SAMD targets that issues a complete Chip Erase
via the Device Service Unit (DSU). This can be used to "unlock" or otherwise
unbrick a chip that can't be halted or inspected, allowing the user to reflash
with new firmware.
Add a "set-security" command which issues an SSB. Once that's done and the
device is power-cycled, the flash cannot be written to until a "chip-erase" is
issued. The chip-erase cannot be issued by openocd at this time because
the device will not respond to a request for the DAP IDCODE.

In the case of xscale, the use of -variant is dubious since
1) it's used as a redundant irlen specifier,
2) it carries a comment that it doesn't really need it and
3) only two xscale configs even specify it.
If there's a future target that needs a variant set, a target specific
option could be added when needed.

This introduces a new global Tcl procedure that is run just after

Its default behaviour is to assign gdb-flash-erase-start and
gdb-flash-write-end to reasonable defaults.
The rationale for doing "reset init" before gdb erases and flashes
memory is that all flash drivers are written in assumption that they
can safely be used only after chip reset (plus chip-specific
configuration in the init handler if any). The need to use "reset
halt" after flashing is because a user expects running firmware after
loading to be the same as running it from power-on-reset.

Re-order the "trace" parameters to allow the raw capture (log) file to

is now the first "required" parameter.
The ST-Link driver is updated to use the (required parameter)
"trace_source_hz" non-zero value as the indicator of trace being
required, rather than the now optional output file descriptor being
non-NULL.
Background: This patch is groundwork for extending the OpenOCD SWO
capture to implement other (OpenOCD built-in) ITM/DWT processing where
the core trace support is required, but there is no requirement to
store raw trace data to a configured host file. By itself this patch
is almost a functional NOP, since without the other processing in
place there is no reason NOT to specify a capture file.

Enable reading the SWO trace output via STLinkv2 dongles that support
it.
This adds an optional initialization parameter "trace" with which the user
specifies a destination file where SWO trace output is appended as it comes in
as well as the trace module's source clock rate.
STLink will be configured for a 2MHz SWO data rate (STLink's highest
supported rate) if the source clock is > 2MHz, otherwise the source
clock is used as the data rate directly.
For example:
trace swo.log 168000000
If "trace" is specified with a usable file path, the stlink_usb driver will
attempt to configure and read SWO trace data as follows:
- on _run(), the target's TPI and TMI are configured and the STLinkv2 is told
to enable tracing. Only generic ARM TPI and TMI registers are
configured, any MCU-specific settings (ex: pin routing) are the
responsibility of the target firmware. The configuration applied is
based on the STLinkv2's capabilities (UART emulation).
- on _v2_get_status(), the trace data (if any) is fetched from the
STLink after the target status is checked and the target is found to
be running.
- on _halt(), the STLink is told to disable tracing.
When fetching trace data, the entire trace frame is written to the output file
and that data is flushed. An external tool may be used to parse the
trace data into a more human-readable format.
Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).

This adds support for JTAG programming by bitbanging GPIOs exposed on
the RaspberryPi's expansion header.
Tested by connecting directly to an STM32VLDiscovery board, without any
additional circuity. I observed maximum about 4MHz on the TCK pin with an
old analogue 'scope and about 100kHz when setting the speed to 100kHz.
Busyloop waiting is needed because even with a single 0ns nanosleep call
(with FIFO priority) it lowers the TCK speed to ~30kHz which is way too low
to be useful.
The speed testing with adapter_khz 2000 gave the following results:
sudo chrt -f 1 nice -n -19 ./src/openocd \
-f interface/raspberrypi-native.cfg \
-c "set WORKAREASIZE 0x2000" \
-f target/stm32f1x.cfg -c "adapter_khz 2000"
wrote 131072 bytes from file random.bin in 3.973677s (32.212 KiB/s)
dumped 131072 bytes in 1.445699s (88.538 KiB/s)
This is 3.7 times faster for writing and 14.3 times faster for reading
compared to the generic sysfsgpio driver; probably the writing speed is
limited by the target itself here and reading speed might be considerably
higher too with appropriate connection and a capable target.
BCM2835 name is choosen over BCM2708 because the published peripherals
datasheet uses the particular model name and not family name.

The SAM4S processors still suffer from the "6 waitstates needed

Other relevant changes are:
1. Address of flash memory starts at 0x400000.
2. EWP (Erase page and write page) only works for the first two 8KB "sectors"
3. Because of the EWP not working for all the sectors, normal page writes have
to be used. The default_flash_blank_check is used to check if lockregions
should be erased.
4. The EA (Erase All) command takes 7.3s to complete. (Previous timeout was
500 ms)
5. There are 128 lockable regions of 8KB each.
Implemented default blank checking, and page erase for load_image scenarios.
This is to compensate for the EWP flash commands only working on the
first 2 8KB sectors.

This patch extends the cortex_m3 maskisr command by a new option 'auto'.
The 'auto' option handles interrupts during stepping in a way they are
processed but don't disturb the program flow during debugging.
Before one had to choose to either enable or disable interrupts. The former
steps into interrupt handlers when they trigger. This disturbs the flow during
debugging, making it hard to follow some piece of code when interrupts occur
often.
When interrupts are disabled, the flow isn't disturbed but code relying on
interrupt handlers to be processed will stop working. For example a delay
function counting the number of timer interrupts will never complete, RTOS
task switching will not occur and output I/O queues of interrupt driven
I/O will stall or overflow.
Using the 'maskisr' command also typically requires gdb hooks to be supplied
by the user to switch interrupts off during the step and to enable them again
afterward.
The new 'auto' option of the 'maskisr' command solves the above problems. When
set, the step command allows pending interrupt handlers to be executed before
the step, then the step is taken with interrupts disabled and finally interrupts
are enabled again. This way interrupt processing stays in the background without
disturbing the flow of debugging. No gdb hooks are required. The 'auto'
option is the default, since it's believed that handling interrupts in this
way is suitable for most users.
The principle used for interrupt handling could probably be used for other
targets too.

This patch extends the cortex_m3 maskisr command by a new option 'auto'.
The 'auto' option handles interrupts during stepping in a way they are
processed but don't disturb the program flow during debugging.
Before one had to choose to either enable or disable interrupts. The former
steps into interrupt handlers when they trigger. This disturbs the flow during
debugging, making it hard to follow some piece of code when interrupts occur
often.
When interrupts are disabled, the flow isn't disturbed but code relying on
interrupt handlers to be processed will stop working. For example a delay
function counting the number of timer interrupts will never complete, RTOS
task switching will not occur and output I/O queues of interrupt driven
I/O will stall or overflow.

This piggy backs on JTAG so it's not yet pretty, but that
seems unavoidable so far given today's OpenOCD internals.
SWD init and data transfer are unfinished and untested, but
that should cause no regressions, and will be addressed by
the time drivers start using this infrastructure. Checking
in whould get the code working better sooner, and turn up any
structural/architectural issues while they're easier to fix.
The debug adapter drivers will provide simple SWD driver
structs with methods that kick in as needed (instead of JTAG).
So far just one adapter driver has been updated (not yet
ready to use or circulate).
The biggest issues are probably
- fault handling, where the ARM Debug Interface V5 pipelining
needs work in both JTAG and SWD modes and
- missing rewrite of block I/O code to work on both of our
Cortex-ready transports (Current code is hard-wired to JTAG);
relates also to the pipelining issue.
- omitted support to activate/deactivate SWO/SWV trace (this is
technically trivial, but configuring what to trace is NOT.

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

Make it scriptable, so code can be conditionalized based on
what transport is in use for the session.
Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
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.

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.)

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.

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.

This command was misplaced; it's not generic to all traceport drivers,

When starting up, say how many hardware breakpoints and watchpoints
are available on various targets.
This makes it easier to tell GDB how many of those resources exist.
Its remote protocol currently has no way to ask OpenOCD for that
information, so it must configured by hand (or not at all).
Update the docs to mention this; remove obsolete "don't do this" info.
Presentation of GDB setup information is still a mess, but at least
it calls out the three components that need setup.

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.

Remove two commands that were documented as "debug commands"

intended to support them, and at least one problem report

Update the docs on the existing register commands to talk a

Add the 'nand verify' command to perform a dump and fake-write
simultaneously, checking the read bits against those generated by the
write process. Appropriate user documentation for this command has
been added to the user guide as well.
The algorithm presently makes a relatively naive comparison. Some chips
that use ECC may not verify correctly using this implementation, but the
new documentation provides details about this limitation.
This documentation update provides an introduction to the command
handling facilities provided by command.[ch]. A primer walks the user
through the elements of a pointedly pedantic module: src/hello.c.
A summary of the API is provided in the OpenOCD Architecture section.
ARM11 and newer cores include updated ETM modules. Recognize
their version codes and some key config differences. Sanity
checked on an OMAP2, with an ETM11RV r0p1 (ETMv3.1).
This still handles only scan chain 6, with at most 128 registers.
Newer cores (mostly, Cortex) will need to use the DAP instead.
Note that the newer ETM modules don't quite fit the quirky config
model of the older ones ... having more port widths is easy, but
the modes aren't the same. That still needs to change.
Fix a curious bug ... how did the register cache NOT get saved??

Start switching MMU handling over to a more sensible scheme.
Having an mmu() method enables MMU-aware behaviors. Not having
one kicks in simpler ones, with no distinction between virtual
and physical addresses.
Currently only a handful of targets have methods to read/write
physical memory: just arm720, arm920, and arm926. They should
all initialize OK now, but the arm*20 parts don't do the "extra"
stuff arm926 does (which should arguably be target-generic).
Also simplify how target_init() loops over all targets by making
it be a normal "for" loop, instead of scattering its three parts
to the four winds.

It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

The semantics of "-work-area-virt 0" (or phys) changed with
the patch to require specifying physical or virtrual work
area addresses. Specifying zero was previously a NOP. Now
it means that address zero is valid.
This patch addresses three related issues:
- MMU-less processors should never specify work-area-virt;
remove those specifications. Such processors include
ARM7TDMI, Cortex-M3, and ARM966.
- MMU-equipped processors *can* specify work-area-virt...
but zero won't be appropriate, except in mischievous
contexts (which hide null pointer exceptions).
Remove those specs from those processors too. If any of
those mappings is valid, someone will need to submit a
patch adding it ... along with a comment saying what OS
provides the mapping, and in which context. Example,
say "works with Linux 2.6.30+, in kernel mode". (Note
that ARM Linux doesn't map kernel memory to zero ...)
- Clarify docs on that "-virt" and other work area stuff.
Seems to me work-area-virt is quite problematic; not every
operating system provides such static mappings; if they do,
they're not in every MMU context...

We currently do something unusual: version codes in config.in get
updated after the release, which means that "git describe" won't
match up to development version labels. Comment that trouble spot.
We can fix this by switching away from the major/minor/micro type
release numbering, as various other projects have done. The major
numbers basically don't tend to change, and doing a good job with
micro versions is so annoying that they rarely change either.
Contrast releases to git snapshot tarballs. Mention that
releases have some quality-improvement focus, with special
non-"dev" version IDs. Explain more about version IDs,
using "openocd -v" to see them, etc;
Make release milestone info be less specific about timing,
and presume we have both a merge window and an RC stage.
Rework the release process information to match reality a
bit more closely. Reference the version.sh script (in one
place the wrong script was referenced). Bugfix branches
get special treatment, while non-bugfix releases are more
or less what *defines* being the mainline branch.

Update documentation to reflect GIT methodology. Rewrite release.sh
script to use appropriate process. With this update, tools/release.sh
can be used for producing private release tags on local branches.
The documentation still needs work, but their use for v0.3.x should

Bit 5 shouldn't be used. Remove all support for modifying it.
Matches the exception vector table, of course ... more than one
bootloader uses that non-vector to help distinguish valid boot
images from random garbage in flash.
The register names are perversely not documented as zero-indexed,
so rename them to match that convention. Also switch to lowercase
suffixes and infix numbering, matching ETB and EmbeddedICE usage.
Update docs to be a bit more accurate, especially regarding what
the "trigger" event can cause; and to split the issues into a few
more paragraphs, for clarity.

hardware, not anything "real".

XSVF improvements:
- Layer parts of XSVF directly over SVF, calling svf_add_statemove()
instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
requirements (which it doesn't).
This should improve XSTATE handling a lot; it removes most users of
jtag_add_statemove(), and the comments about how it should really do
what svf_add_statemove() does.
- Update XSTATE logic to be a closer match to the XSVF spec. The main
open issue here is (still) that this implementation doesn't know how
to build and submit paths from single-state transitions ... but now
it will report that error case.
- Update the User's Guide to mention the two utility scripts for
working with XSVF, and to mention the five extension opcodes.
Handling of state transition paths is, overall, still a mess. I think
they should all be specified as paths not unlike SVF uses, and compiled
to the bitstrings later ... so that we can actually make sense of the
paths. (And see the extra clocks, detours through RUN, etc.)
