Tomas Vanek fd8a3c9516 target, breakpoints: improve error handling
handle_bp_command_set() showed the error message
"Failure setting breakpoint, the same address(IVA) is already used"
on any error returned from (xxx_)breakpoint_add().
Paradoxically breakpoint_add() returned ERROR_OK if it detected
duplicated bp address.
context_breakpoint_add() and hybrid_breakpoint_add() returned -1
instead of OpenOCD compatible error if they detected duplicity.

Introduce ERROR_TARGET_DUPLICATE_BREAKPOINT
Unify error handling to LOG_ERROR() any error in (xxx_)breakpoint_add()
Remove misleading error messages from handle_bp_command_set()
handle_bp_command_set() returns error if the target does not implement
add_context_breakpoint or add_hybrid_breakpoint.

Marc Schink 6c2020eb48 jlink: Use correct SWD buffer size
Currently, the SWD buffer size is adjusted corresponding to the free
device memory. However, the adjusted size is not used.

This fixes SWD operations on devices with small device memory, such as
EFM32PG12 Pearl Gecko STK. It should also fix #184.

Antonio Borneo 3117a318d4 command: fix the mode for command "jtag configure"
Before commit 877cec20dc ("command:
check command mode for native jim commands") all the jim commands
were erroneously treated as they had mode COMMAND_ANY.
The commit above fixes the code in order to check the mode and
permit running the commands only if the mode is respected.

Those jim commands that have incorrect mode were not detected nor
fixes because the wrong mode was masked by the missing mode check.
After the commit above, the wrong mode triggers error in several
existing configuration scripts.
A complete list of commands that now does not run anymore as
CONFIG_ANY is reported in ticket 225, but most of them have the
mode set correctly.
At least two instances of command "jtag configure" have the wrong
mode.

Fix the mode to CONFIG_ANY for command "jtag configure" in files
src/jtag/aice/aice_transport.c and src/jtag/tcl.c

Jan Vojtech 9f576d3f48 flash/nor/stm32f1x: Ability to change user option bytes.
Adds ability to change the user data in STM32F1x/STM32F3x MCU's option byte.
Since OpenOCD prints the content of user data in option byte registers, it
is seems logical to also provide a way how to change this data.

Tomas Vanek deaf3d2641 flash/nor: flash driver and cfg for SAM E54, E53, E51 and D51
The new Microchip (former Atmel) series powered by Cortex-M4 looks
very similar to older M0+ powered SAM D2x at the first sight.
Unfortunately the new series differs a lot in important details.
NVMCTRL has different register addresses, moved important bits
and even changed binary command set. An universal driver for all SAM D/E
would be very complicated. That's why a new driver was derived.

Tested on Microchip SAM E54 Xplained Pro kit (board cfg included).

Adjusted for the restructured dap support.
Checked by valgrind and clang static analyzer.

Antonio Borneo 7a80a74e81 arm_adi_v5: rewrite dap_to_jtag and dap_to_swd
The functions dap_to_jtag() and dap_to_swd() have been introduced by
3ef9beb52c ("ADIv5 DAP ops switching to JTAG or SWD modes") in
arm_adi_v5.c by using the JTAG queue only.
Later, in 6f8b8593d6 ("ADIv5 transport support moves to separate
files") the functions has been moved in adi_v5_swd.c and adi_v5_jtag.c
but keeping the dependency from JTAG queue.
The functions does not work if the current transport is not JTAG.

Move back the functions in arm_adi_v5.c, replace the input parameter
"target" with "dap", use the transport to detect if the JTAG queue is
present, in case of SWD transport use the proper method, for other
transports report error.
Reuse the ADI v5 sequences already present in jtag/swd.h.
Also, OpenOCD does not support switching to another transport after
the initial selection, so do not change DAP's ops vector.

All the commands in OpenOCD have been inspected and have the

This is not critical, because the uninitialized value (0) is
equivalent to the enum COMMAND_EXEC, that is also the correct

To keep the code consistent, initialize the command mode to

Antonio Borneo c2e18bfaea arm_adi_v5: fix and update sequences to spec IHI 0031E
Fix the SWD line reset sequence accordingly to Arm specification IHI
0031E that requires at least 2 idle clocks after the 50 clocks with
SWDIO high.
Fix the value of the activation code in the (currently unused)
sequence dormant-to-SWD.
Make each sequence's length multiple of 8, so it is compatible with
adapters that have such limitation (e.g. buspirate) and try to split
and comment each part of the sequence (when possible keep each part
byte aligned, inspired from commit 3ef9beb52c). This slightly
increases the sequence length but does not impact run-time
performance because these are rarely used sequences.
Add the missing sequence dormant-to-JTAG and JTAG-to-dormant, not
used yet.

On devices that implements the dormant state, IHI 0031E deprecates
the direct switching between SWD and JTAG, and recommends using a
transition through dormant. This is not implemented.

Austin Phillips 42d8fa899c stlink_usb: Submit multiple USB URBs at once to improve performance
Commands to stlink devices are typically comprised of multiple
transactions with each transaction completing before moving to the next.
This change allows for multiple USB transactions to be issued at once
followed by a check that all transactions completed successfully.  This
improves performance on some machines where there is a large turn-around
time between USB transfers such as is seen on some virtual machines.

This change is only supported when compiled with libusb1 as libusb1
supports and asynchronous interface.

Multi-transaction queueing introduced in this change paves the way for
improving speed of other transactions in the future such as memory and
register reads where multiple USB transactions in succession are
required to complete a command.  Multiple USB transactions can be
submitted at once using jtag_libusb_bulk_transfer_n function.

Cody P Schafer 49bd64347a armv7m: always set xPSR.T=1 when starting an algorithm
xPSR.T sets the processor to Thumb mode when set to 1. ARMv7-M only
supports execution of Thumb instructions, so it must always be set to 1.

If xPSR.T is set to 0 on armv7m, a usage fault is generated when a
instruction execution is attempted.

On armv7m, issuing a reset causes the vector table to be examined. PC
and xPSR.T  are loaded from the vector table at byte offset 4. xPSR.T is
taken from the least significant bit this value, PC from the remaining
bits.  This occurs even with `reset halt`, as the reset itself causes
this load to occur without the execution of any instructions.

As a result of this, following a reset with a "bad" value programmed in
the vector table, openocd would be unable to run algorithms on the
target, as running them would immediately result in a usage fault due to
xPSR.T being unset (0).

Allow algorithms to run regardless of the content of the vector table by
explicitly setting xPSR so that xPSR.T=1 prior to executing an
algorithm. One can think of this as openocd more closely emulating a
reset or branch instruction in executing it's algorithms.

Antonio Borneo bff87a7f28 target/cortex_a: enable DSCR_HALT_DBG_MODE during examine
Arm architecture reference manual DDI0406C reports at page 2024 in
table C3-1 the processor behaviour on debug events depending on
the debug-mode (none, monitor or halt), mode selected through the
bits MDBGen and HDBGen in DSCR register.

The halt request is served independently from the debug-mode. Thus
it's useless to enable the halt debug-mode in cortex_a_halt() by
setting the bit HDBGen (macro DSCR_HALT_DBG_MODE).

On the other side, halting for a breakpoint, a watchpoint or a
vector catch requires being in halt debug-mode.
Today HDBGen is set only in cortex_a_halt(), so we are forced to
halt the core at least once before it can be halted for hitting a
breakpoint/watchpoint/vector-catch. This is annoying since there
is no need to halt the target to set a HW breakpoint.

Move in cortex_a_init_debug_access() the selection of the halt
debug-mode, so the mode is set during examine.
To prevent a misconfigured hardware breakpoint/watchpoint/vector
catch to halt the target when OpenOCD has already quit, return to
debug-mode none at OpenOCD exit.

Antonio Borneo 334552bc83 helper/startup.tcl: fix execution stack frame of wrapped commands
The OpenOCD commands that have been wrapped with 'ocd_bouncer' are
executed within two levels of nested proc's:
	# see register_command_handler() in src/helper/command.c
	proc my_command {args} {eval ocd_bouncer my_command $args}

	# see ocd_bouncer in src/helper/startup.tcl
	proc ocd_bouncer {name args} {
		... [eval ocd_my_command $args] ...
	}
This causes the stack frame of 'ocd_my_command' to be the same one
of proc 'ocd_bouncer', thus two levels below the stack frame of the
caller of 'my_command'. This is an issue with commands that receive
a variable by name and have to resolve them to access the value.

E.g. the command
	<target> mem2array arrayname bitwidth address count
is wrapped; it receives the name of the array but fails to resolve
it in the current stack frame. Instead, the commands
	mem2array arrayname bitwidth address count
	ocd_<target> mem2array arrayname bitwidth address count
are not wrapped and can directly access the array because they share
the same stack frame of the caller.
Same situation with the symmetric commands 'array2mem'.

How to test:
within a telnet connection, run the following set of commands,
eventually replacing the address 0x08000000 with a valid readable
address of your <target>,
	unset -nocomplain v1 v2 v3
	info vars v?
	mem2array v1 32 0x08000000 1
	<target> mem2array v2 32 0x08000000 1
	ocd_<target> mem2array v3 32 0x08000000 1
	info vars v?
and notice that only v1 and v3 are now allocated. The array v2 has
been allocated in the temporarily stack frame of proc ocd_bouncer,
together with its local variables, and then lost when proc ended.

Fixed by executing the wrapped commands with the command 'uplevel'
instead of 'eval'. The amount of levels to skip is checked to avoid
errors in the unusual case 'ocd_bouncer' is called directly without
the first level of wrapper.

Antonio Borneo 717d3af087 stlink: remove reset pulse when entering in JTAG
Until version J14 the behaviour of ST-Link was to send a reset
pulse to the target when the debug connection is started in JTAG
mode. No reset pulse is sent, instead, in SWD mode.
Version J15 introduces a new parameter to avoid the reset pulse in
JTAG mode, aligning the behaviour with SWD.

This reset from the ST-Link, if propagated to the target, prevents
attaching a running target.

Actually this reset pulse is very short (few microsecond) and can
be easily filtered out by an on-board capacitor, usually present
on the reset wire (mainly to filter the bounces of the reset
button). Moreover, most of the use cases for ST-Link are with SWD
(not with JTAG) and this has probably further masked this JTAG
specific behaviour.

OpenOCD can tolerate it but requires the flag "connect_assert_srst"
to the command "reset_config", but the flag is not present in any
configurations in folder tcl. This enforces the guess it was not
noticed due to on-board capacitors or missing connection of reset
pin or ST-Link only used in SWD; so it's safe applying this patch.

Change the default behaviour to avoid reset in JTAG at connection.
There is no need to manage the ST-Link version here, since every
parameter that is not recognized by older ST-Link is treated as
"connect in JTAG with reset pulse", keeping backward compatibility.

Christopher Head ea41048830 Permit null target on TCL connection
In previous versions of OpenOCD, it was possible to connect to the TCL
RPC interface without a current target. In `tcl_new_connection`, the
curent target would be queried by number, and the possibility of a null
current target was handled properly.

In commit bb9d9c6026, the
`get_target_by_num` call was replaced by a `get_current_target` call,
without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.

Provide a `get_current_target_or_null` function for use by consumers who
are OK with a null current target, and use it in `tcl_new_connection`.

Antonio Borneo fac9be64d9 target/cortex_a: remove buggy memory AP accesses
The armv7m debug port provides a direct access to the CPU memory
bus, allowing the debugger to bypass the CPU for every memory
operation.
The armv7a debug port doesn't offer the same feature, mainly
because CPU caches and MMU makes the direct memory access more
tricky. Nevertheless most SoC with armv7a provide direct memory
access through an AHB bus available on another DAP access port,
different from the debug port.

The original port of cortex_a in OpenOCD was inspired from the
working cortex_m code, and provided optional memory access
through the AHB, if present.
The code for AHB access is problematic and partially buggy due
to incomplete management of cache coherency and missing check of
page boundary during virtual address operations.

With the commit 5d458cf727
("target/mem_ap: generic mem-ap target") we have a clean support
for memory access through system buses connected to DAP AP, which
obsoletes the buggy memory AP hack in cortex_a.

Remove any code that uses the memory AP accesses in cortex_a.

Antonio Borneo 1e3ba2046c arm_adi_v5: do not deactivate power domains while trying to clear sticky error
At OpenOCD start-up the operation of clearing the sticky error in
CTRL/STAT register ignores the current value of the power domains
bits CDBGPWRUPREQ and CSYSPWRUPREQ in the same register and
incorrectly set them to zero.
This abrupt disable does not follow the requirement in IHI0031 to
wait for the acknowledgment of power disabled before continuing.
The power domains are then re-enabled immediately after; it is
possible that such short disable period has passed undetected or
has been tested only on devices that do not implement the power
domains.
Anyway, this sequence is incorrect and can generate unexpected
and hard-to-debug issues while OpenOCD attaches to a running
target that implements power domains.

Anticipate the initialization of dap->dp_ctrl_stat and use it
while clearing the sticky bit. This has the additional effect of
avoiding a power disable in the error recovery part of the
function dap_dp_read_atomic().
Keep the same sequence of read/write in dap_dp_init() to avoid
breaking the initialization of some problematic target.
Add comments to document these choices.

The performance of CMSIS-DAP in long data transfers was improved substantially in
ef02b69b14. But it not as good as some
other USB/MCU based adapters. Using HID and therefore interrupt endpoint
is slower than USB bulk transfer.

CMSIS-DAP adapter implements multiple HID buffer handling and OpenOCD already
reads number of buffers from info command.

This change adds capability to sumbit more than one HID requests before
driver waits for a HID response. This scenario is used for long transfers only.
Results show about double speed on USB FS and ~140% speed on USB HS:

Antonio Borneo cf81de7052 target/cortex_a: fix temporary breakpoint during step
Commit c8926d1457 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.

The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".

Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".

Fixed by initializing "asid" to 0 in cortex_a_step().

Fixes: c8926d1457 ("cortex_a hybrid & context breakpoints")

Antonio Borneo 1ba715422f target/arm_adi_v5: fix sync CSW cache on apreg write
Commit 0057c71ab6 updates the OpenOCD
cached values of CSW and TAR registers if these registers are modified
by an apreg command.
The condition to force the update of CSW cache is incorrect and it will
erase the default CSW value.
Moreover, calling mem_ap_setup_csw() does not honor the value requested
in the apreg command because such value is incorrectly bitwise or-ed
with csw_default.

Fix it by updating csw_value, instead of erasing csw_default, and writing
directly in CSW register the new value from the command line.

The issue is caused in cmsis_dap_init() by anticipating the call to

following test to always fail.
Actually the original code was quite tricky:
	if (swd_mode)
		do something that also sets cmsis_dap_handle;
	if (cmsis_dap_handle == NULL)
		do something for !swd_mode;

Convert the sequence of tricky "if"s in a single "if-then-else" to
handle clearly the cases swd_mode and !swd_mode.

Virtual targets, like mem_ap, do not or cannot implement the required
functionality to accept a GDB connection. In the case of mem_ap, the
method get_gdb_reg_list() is missing and a following connection from
gdb causes OpenOCD to segfault.
OpenOCD opens a GDB port for each target; it's always possible to
connect, by mistake, GDB to one virtual target.

Add a method to check if the target supports GDB connections (for the
moment just checking if get_gdb_reg_list is implemented).
Skip opening a gdb server for every targets that don't support GDB
connections.

Antonio Borneo 56cdc3f3d5 target/cortex_a: poll all targets in SMP node after halt
The periodic poll scans all the targets in the same order they
have been declared in the configuration file.
When one target in a SMP node halts, the transition is detected
in the following poll and this triggers a halt request to all the
other cores of the SMP node.
The targets that will be polled afterwards will be identified as
"halted", but the targets already scanned will remain as
"running" until the next periodic poll.
This creates a race condition with GDB; GDB sets the breakpoints
when runs the target and removes them as soon as the target is
halted. When it receives the halt event, it starts removing the
breakpoints and fails on the targets that are still reported as
"running".

Fixed by polling all the targets in the SMP node before informing
GDB about the halt event.
This implementation is almost copy/paste from the one in aarch64.

Antonio Borneo ab858febb6 gdb_server: add per target option "-gdb-port"
The argument passed to global config command "gdb_port" is usually,
but not always, a TCP port number. In case of multiple targets, this
numeric value is used as the first port of a set of consecutive TCP
ports assigned one per target.
If the argument is not a numeric value (e.g. "pipe", "disabled", ...)
then incrementing it for the next target has no sense.

Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.

This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.

It also makes possible to choose a custom TCP port number for each
target, overriding the usual sequence of consecutive port numbers.

Christopher Head c6cc60e0e1 target/cortex_m: restore C_MASKINTS after reset
The cortex_m maskisr user-facing setting is not changed across a target
reset. However, the in-core C_MASKINTS bit was always cleared as part of
reset processing, meaning that a cortex_m maskisr on setting would not
be respected after a reset. Set C_MASKINTS based on the user-facing
setting value rather than always clearing it after reset.

Antonio Borneo 527113ad2b target/armv7a_cache: add gdb keep-alive and fix a missing dpm finish
Depending on range size, the loop on cache operations can take quite
some time, causing gdb to timeout.

Add keep-alive to prevent gdb to timeout.
Add also a missing dpm->finish() to balance dpm->prepare().

Antonio Borneo 766d6114fe target/cortex_a: allow command dacrfixup during init phase
There is no reason to restrict the command "cortex_a dacrfixup"
to the EXEC phase only.
Change the command mode to ANY so the command can be used in
the initialization phase too.

Antonio Borneo e48690cb26 target/arm_adi_v5: allow commands apsel and apcsw during init phase
The current implementation of apsel cannot be executed during the
initialization phase because it queries the DAP AP to retrieve and
print the content of IDR register, and the query is only possible
later on during the exec phase.
But IDR information is already printed by the dedicated command
apid, making redundant printing it by apsel too.
Being unable to run apsel during initialization, makes also apcsw
command (that depends on apsel) not usable in such phase.

Modify the command apsel to only set the current AP, without making
any transfer to the (possibly not initialized yet) DAP. When run
without parameters, just print the current AP number.
Change mode to COMMAND_ANY to apsel and to apcsw.
