The TI TMS470 and TMS570 series of processors are BE-32 processors,
despite BE-32 not being supported by ARM in the Cortex-R4 core. TI
hacked in BE-32 support, which requires odd swizzling in OpenOCD to
make memory reads and writes function correctly. In particular,
without this change, OpenOCD word reads and writes had the bytes
reversed, and halfword and byte packed reads were reading garbage.
In my testing, this change fixes these problems.

Some fixes to 'samd_protect' including:
- Fix a bug in which the value of 'set' parameter passed into the
function was ignored so it was impossible to remove flash
protection once it was set.
- Check the protection status of the sector via 'is_protected'
field of the corresponding 'flash_sector' structure to see if
any actual HW manipulations needs to be done.
- Change the way the errors during protection activation are
handled. Now even in the case of error in the middle of
protecting a number of sectors the subroutine would still update
the state of the sector protection in sectors array so as to
avoid cases where openocd thinks that the sector is not protected
while it actually is.

This introduces a new global Tcl procedure that is run just after
init_targets and before init_boards.
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.

The JLink-OB (onboard) devices work the same way as the normal JLink
except that their PID is 0x0105 (and that's the only one we know of so
far) and their endpoint addresses are different due to there being a
CDC-ACM interface as well. These JLink-OB devices show up on a lot of
vendors' development kits as an integrated debugger.
This change simply checks whether the adapter we opened has a JLink-OB
PID and, if it does, uses the JLink-OB endpoints rather than the
default. To do this, we add a new routine, jtag_libusb_get_pid() to the
libusb adapter layer, it in turn just calls
libusb_get_device_descriptor(), which previously had no wrapper.
Also, checkpatch.pl doesn't like the VID/PID macros as defined so I
moved them to the array itself. This should have no effect on the code.
This change adds the 0102 through 0104 PIDs to openocd.rules as well as this
new 0105 PID.
Tested on an Atmel SAM4S Xplained board which has a JLink-OB, also
regression tested by using a 0x0101 PID normal JLink adapter.

Atmel's SAM3 and SAM4 processor families are very close to each other
in many respects. However, so far, only the SAM4 target script
contained the magic to allow using SWD, while SAM3 was tied to JTAG
only. This e.g. prevented the CMSIS-DAP driver from accessing SAM3
devices as it only uses SWD transport (by now).
The patch pulls all the things from the SAM4 target script that are
also applicable to SAM3 devices. With the patch, an Atmel CMSIS-DAP
debugger (Atmel-ICE) was proven to be able to successfully attach to a
SAM3S-EK evaluation kit. I also cross-checked that accessing through
a SAM-ICE (Segger J-Link) still works with the patch.

The existing CMSIS-DAP driver matches the USB VID/PID against 0x3eb
(Atmel VID) and 0x2111 (Atmel EDBG embedded CMSIS-DAP debugger), and
then bumps the packet size from its default of 64 to 512. However, it
turned out that *all* Atmel-provided CMSIS-DAP devices (EDBG with PID
0x2111; JTAGICE3 with firmware version 3.x, PID 0x2140; new Atmel-ICE
[successor of JTAGICE3], PID 0x2141) require a 512-byte packet size.
Obviously, all run the same USB implementation inside their custom
microcontroller. Thus, it seems best to simply assume that *all*
Atmel CMSIS-DAP devices use this packet size, and don't check the PID
at all.

The ST-LINK/V2 has limited internal buffering, such that trace data
can be missed if the target is generating data at a rate quicker than
the OpenOCD trace sampling. The issue of lost data is compounded since
individual TPIU packets may be split across individual STLINK_TRACE_EP
reads, and misleading results can occur if mid-packet loss occurs.
This patch increases the frequency of checking for pending trace data
with the aim of minimising such losses. Note: With the limited (I/O
and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a
guarantee against trace data loss.
The timer callback is only added when enabling tracing, and is removed
when tracing is disabled.

Comment in gdb_server code mistakenly attributed constant warnings
about unexpected acknowledgement to the ACK packet sent by GDB when
establishing connection. However that is not the case, OpenOCD
gdb_server is handling this packet correctly without an warnings. This
warning instead was caused by the ACK packet which GDB sends right after
going into noack mode. Because OpenOCD gdb_server is already in noack
mode at this state, it emits warning about it. This is a documented GDB
behaviour
(https://sourceware.org/gdb/onlinedocs/gdb/Packet-Acknowledgment.html)
so there is no reason to scare users with warnings in this case.
This patch basically introduces two-level noack mode: after receiving
QStartNoAckMode gdb_server will set noack_mode to 1, then it will
receive this last ACK packet, but instead of printing a warning,
noack_mode will be increased to 2. Should there be any other ACK packets
after that, they will be properly reported by warning. All other code
that relies on noack_mode checks it for "!= 0", so there will be no
difference if it is 1 or 2.

The Cypress chip as an embedded 8051 microcontroller.
When it's powered up, the firmware is downloaded to the
chip then the device is disconnected and reconnected with
the new firmware.
The USB-Blaster II protocol is almost identicial to
the old one. The only difference is that you need to
send a 0x5F before read TDO back. This command
seems to copy TDO buffer datas to the endpoint buffer.
Driver will be auto enabled if libusb-1.0 is detected.

This adds the bcm47xx config with the special undocumented trick to
put it into standard EJTAG mode from the mystic "LV mode".
The RAM setup is not done as it would require considerable efforts
without much practical gain.
The only issue I noticed so far is that "reset" doesn't actually reset
the chip.
Unfortunately, it's unclear how to make it work properly with SRST as
OpenOCD asserts it in MIPS-specific code so the device will enter LV
mode again but the LV tap is already disabled by that time, so it's
not possible to send the magic command again.
Anyway, this config is more than enough to "recover" any RT-N16
provided the hardware is not damaged.

On Windows, set run_prefix to the runtime path of the executable, minus

run_prefix is empty.
The script paths can now be adjusted on Windows builds the normal way; by

of going via void*.
Don't explicitly cast to void* if it would have been done implicitly.

Don't use const on pointers that hold heap allocated data, because that

Do use const on pointer parameters or fields that needn't be modified.

Re-order the "trace" parameters to allow the raw capture (log) file to
be an optional feature. The clock frequency for calculating the "Async
Clock Prescalar" is always required when enabling trace processing and
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.

Add a mandatory field in struct arm7_9_common for regular, non-optimized
memory writes. Together with the existing bulk_memory_write field, this
allows variants to select any combination of implementations for regular
and bulk writes, without risking infinite loops from accidentally using
bulk writes for implementing bulk writes.
ARM 7/9 targets may now select arm7_9_memory_write_opt as their
target.write_memory implementation, which will dispatch to
arm7_9_common.bulk_write_memory if possible, or fallback to
arm7_9_common.write_memory otherwise.
To avoid loops, bulk write implementations mustn't call any other
functions than arm7_9_write_memory_no_opt() to write memory; it will
unconditionally call arm7_9_common.write_memory. If they fail, they should
simply return error to allow the caller to fallback to regular writes.
Tested on a regular ARM7TDMI only.

This unifies the way the USB adapters are handled, and enables them
automatically whenever possible (until explicitly disabled). If an
adapter is explicitly enabled but can't be built, abort the
configure.
Also add infrastructure for generic handling of adapter drivers in
configure and print a summary of the configuration results after
finishing.
The m4 quoting is as conservative as I could get it, and seems
appropriate.

An alternative approach to show how much cleaner the pure pkg-config
way is.
This changes the discovery procedures for libusb-1.0 and libusb-0.1,
making them depend on pkg-config being properly installed and
configured, including the necessary build host configuration for the
cross-builds (see
http://www.flameeyes.eu/autotools-mythbuster/pkgconfig/cross-compiling.html)
It should make it possible to compile OpenOCD without changes and
extra effort on GNU/Linux, FreeBSD users would need to supply a .pc
file for their libusb implementation or add LIBUSB1_LIBS and
LIBUSB1_CFLAGS to the configure environment.

This is an attempt to bring the README files in line with the current
status of the OpenOCD development.
- remove some obsolete information and duplicated instructions
- reword some statements
- restructure in a way more appealing to a regular user
- add a supported hardware list to allow a potential user to determine
if his/her usecase is covered by a freetext keyword search through
the document
- Add OSX notes (courtesy GrizzlyAdams and inca)
Since most ftdi-based adapters are now covered by the ftdi driver, I
think it's ok to remove some of the libftdi/ftd2xx instructions, the
few users who still need them should refer to upstream docs instead.
I'm not sure if README.Windows should come with the DOS line endings,
but i'd expect many windows users to use their silly notepad to view
it, and notepad ignores LF apparently. (Decided to use LF anyway.)
I understand discussing and reviewing such a massive README change is
a somewhat demanding task but I feel it's a necessity to move forward
maintaining proper documentation.

Adds a flash driver for Nuvoton MINI51, MINI52 and MINI54 microcontrollers.
At the moment, it only supports the erase and write operations.
These microcontrollers have a 4 / 8 / 16 KB APROM for application code and a
2 KB LDROM for bootloaders. When the MCU has booted off the APROM, the LDROM
isn't mapped in memory but can be programmed, and the other way around.
This means that the ARM core is typically rebooted for programming. After a
successful write or erase operation, it is rebooted again, using the initial
boot source.
This driver only supports programming the APROM.
This driver is a pure JTAG implementation, it doesn't use any SRAM.
I've tested it on a MINI54ZAN microcontroller using an ST-LINK/V2. With the
microcontroller running at the default clock frequency of 22.1184 MHz, speed
seems to be around 1.1 KB/s.

This adds example config and flash driver for russian Cortex-M3
microcontroller model.
Run-time tested on MDR32F9Q2I evaluation board; the flash driver
should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware
to test.
There're no status bits at all, the datasheets specifies some delays
for flash operations instead. All being in <100us range, they're hard
to violate with JTAG, I hope. There're also no flash identification
registers so the flash size and type has to be hardcoded into the
config.
The flashing is considerably complicated because the flash is split
into pages, and each page consists of 4 interleaved non-consecutive
"sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the
fastest way is to latch the page and sector address and then write
only the part that should go into the current page and current sector.
Performance testing results with adapter_khz 1000 and the chip running
on its default HSI 8MHz oscillator:
When working area is specified, a target helper algorithm is used:
wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s)
This can theoretically be sped up by ~1.4 times if the helper
algorithm is fed some kind of "loader instructions stream" to allow
sector-by-sector writing.
Pure JTAG implementation (when target memory area is not available)
flashes all the 128k memory in 49.5s.
Flashing "info" memory region is also implemented, but due to the
overlapping memory addresses (resulting in incorrect memory map
calculations for GDB) it can't be used at the same time, so OpenOCD
needs to be started this way: -c "set IMEMORY true" -f
target/mdr32f9q2i.cfg
It also can't be read/verified because it's not memory-mapped anywhere
ever, and OpenOCD NOR framework doesn't really allow to provide a
custom handler that would be used when verifying.

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.

As debugging multi-targets, every target has its own gdb connection.
If there are two connections, gdb_target_callback_event_handler will
be registered twice. Everytime event occurs, the registered callback
will be executed twice. If both targets are running, as user issues
ctrl-c in one gdb client, both connections will send "stop reply" to
GDB clients even TARGET_EVENT_GDB_HALT is caused by one of them.
The commit fix above problem as debugging multi-targets.

The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.
To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target
As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).
To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.
Details refer to GDB manual "File-I/O Remote Protocol Extension"

Simplify the API by making all MPSSE command functions return void instead
of an error code. If there is an error during an implicit flush in a
command call, further commands are ignored until an explicit flush is
performed. The flush function returns and clears any error code set.
The only command functions that still return an error code are those that
can fail directly based on the type of the FTDI chip, i.e. when trying to
enable RCLK or divide-by-5 on a non-high-speed chip.
Adapt the ftdi adapter driver to the new API.

to connect to an ETM-equipped target (i.MX25 ARM9 in my case), this
results in writing garbage values in the etm reg_cache as the ETM bit
fields for the comparators, counters and outputs are wider than the
amount of entries in the corresponding arrays. This later results in a
segfault in the first etm_reg_lookup() call.

mips_m4k_bulk_write_memory was only called from target_write_buffer as an
optimization when the word count was large enough.
Remove mips_m4k_bulk_write_memory from the target type, causing the default
implementation to call the regular mips_m4k_write_memory instead.
Perform the dispatch to bulk write in mips_m4k_write_memory, enabling the
optimization for target_write_memory() writes with size 4, in addition to
target_write_buffer() writes.
It also enables making the choice of bulk write vs regular write
specifically for the architecture and not relying on the generic target

This makes libusb handling more consistent: if any driver requires
libusb, first check for libusb-1 availability, if not found and
libusb0 is ok for this case, try libusb0.
A user-visible bug fixed by this is that when a user was selecting a
driver that required libusb-1 but was lacking the necessary dev files
or libraries, configure didn't complain (but the build was failing of
course).
--enable-stlink doesn't really require libusb-1 but since it's using the
same automake symbol HLAADAPTER, ti_icdi is getting built too which needs
libusb1 unconditionally. Since using libusb-0.1 makes little sense anyway,
leave that as is.

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.

it's not present. Currently it's impossible for the user to enable

NOTE: I could only program flash successfully when the chip is powered

Note: flash program testing required hacking kinetis_write() to force
longword programming, as the FTFL program section commands formulated by

Functions mips32_pracc_read_mem(), mips32_cp0_read() and mips32_pracc_read_regs() are now modified.
mips32_cp0_read() is very similar to mips32_read_u32() with one store access.
mips32_pracc_read_regs() is the only function that can not be executed from only one queue.
Now this function is modified to use reg8, it saves all the registers but does not restore reg8.
To remedy this, mips_ejtag_config_step() is called after mips32_save_context() in
mips_m4k_debug_entry(). Function mips_ejtag_config_step() is modified to use reg8 and
restore it from ejtag info instead of using DeSave for save/restore.

Each pracc function defines a variable ctx of type struct pracc_queue_info.
To simplify the code tree auxiliary functions are defined: pracc_queue_init(), pracc_add() and
pracc_queue_free().
The second parameter in pracc_add() is the store address if the instruction is a store at dmseg,
otherwise it should be 0.
The code is executed by mips32_pracc_queue_exec(). If ejtag_info->mode is 0 mips32_pracc_exec()
is called and it should work like with current code.
To generate the delay between scans the number of clock ticks are calculated with the help of
jtag_get_speed_khz(). Due to delays in the execution of each single ftdi instruction the number of ticks
are higher as it should be, specially at higher scan rates.
mips32_pracc_read_u32() should now work with the new code.

This patch and the following patches define another way of doing processor access without the need to read back
the pracc address as needed in current pracc code.
Current pracc code is executed linearly and unconditionally. The processor starts execution at 0xff200200
and the fetch address is ever incremented by 4, including the last instruction in the delay slot of the branch to start.
Most of the processor accesses are fetch and some are store accesses.
After a previous patch regarding the way of restoring registers (reg8 and reg9), there are no load processor accesses.
The pracc address for a store depends only on the store instruction given before.
m4k core has a 5 stage pipeline and the memory access is done in the 3rth stage. This means that the store access
will not arrive immediately after a store instruction, it appears after another instruction enters the pipeline.
For reference: MD00249 mips32 m4k manual.
A new struct pracc_queue_info is defined to help each function in generating the code. The field pracc_list holds in the
lower half the list of instructions and in the upper half the store addressess, if any. In this way the list can be used by
current code or by the new one to generate the sequence of pracc accesses.
For every pracc access only one scan to register "all" is used by calling the new function mips_ejtag_add_scan_96().
This function does not call jtag_execute_queue(), all the scans needed can be queued before calling for execution.
The pracc bit is not checked before execution, is checked after the queue has been executed.
Without calling the wait function the code works much faster, but the scan frequency must be limited. For pic32mx
with core clock at 4Mhz works up to 600Khz and with 8Mhz up to 1200. To increase the scan frequency a delay
between scans is added by calling jtag_add_cloks().
A time delay in nano seconds is stored in scan_delay, a new field in ejtag_info, and a handler is provided for it.
A mode field is added to ejtag_info to hold the working mode. If a time delay of 2ms (2000000 ns) or higher is set,
current code is executed, if lower, new code is executed.
Initial default values are set in function mips32_init_arch_info. A reset does not change this settings.

The em357 driver only supported one page configuration (192k in 96 2048k)

ST's STM32W chips (pretty much the same) have different flash
configurations available (64, 128, 192, 256k). I can't find anywhere
that would indicate the size of the chip anywhere in memory so the
selection must be manual, using the 'size' parameter. For backwards
compatibility, any size not known to be in use defaults to the 192k
configuration. I don't have any em357 devices to test, but I also found

In current devel code there are 3 functions (related to m4k code) that need to restore register 8 from pracc stack:
mips32_pracc_read_u32()
mips32_cp0_read()
mips32_pracc_write_mem_generic()
And mips32_pracc_read_mem() needs to restore regs 8 and 9 from pracc stack.
Values in this registers should be the same as read by mips32_pracc_read_regs() when entering debug
mode and can be modified by mips32_pracc_write_regs() when leaving debug mode.
There is no need to read their values from the processor registers every time.
The fields reg8 and reg9 are added to struct mips_ejtag to store these register values
and the call to mips32_save_context() is shifted in mips_m4k_debug_entry() in order
to store them before any other function needs to restore these registers.
For the same reason in function mips_m4k_step() the call to mips_m4k_set_breakpoint(), if needed,
should be made after calling mips_m4k_debug_entry().
For single word write the number of pracc accesses are now 9 or 8, from 13 or 12 in current code,
single word read takes now 10 instead of 12.
This patch is really the first in a set of patches for an alternate m4k pracc code
much faster that current code. At least for me with pic32mx works fine.

To show up the fail try to step with the core clock set to 31.25Khz
and with a ftdi/hs adapter or with a wiggler, -not with ft2232-.
The scan frequency should be set to 300Khz or higher, at lower frequency probably will not fail.
The code exits with error because the pracc address is at 0x0.
It also fails when using the "all" register, but in this case the code works without any message because the
pracc address is at 0xff202004 when it fails.
I never saw this fail with the core clock set to 500Khz or higher, but ...
The workaround simply puts a 1 ms delay after the execution of the DERET instruction.

When the ftdi driver calls finally the mpsse_flush function, it first
initiate the USB in and finally the corresponding USB out transaction.
Because data in is requested too early the USB device will always answer
the first USB in by a NAK. That can prevented by a simple reordering of
the out and then the in transfer and can improve the Jtag performance for
high JTAG clock rates.

This update adds support for the STM32Lx 384kb dual bank flash. Previously there was a problem when writing an
image that was larger than 192Kb. That lead to openocd printing out two error messages like
"Error: access denied / write protected" and "Error: invalid program address". The reason was that the stm32lx
driver tried to write half pages which overlapped into the next flash bank.
A new configuration file stm32lx_dual_bank.cfg can be used for stm32lx chips with dual bank flash (256kb or 384kb devices).
A sanity check was added for probed flash size values to fix the issue seen on some ST samples that answered incorrectly.

Two solution's seem to workaround this issue:
1, Handle the exception, this means adding exception vectors to the loader
and changing the exception address using nvic vtor register.
2. falling back to using slower direct page writes - approx 50% slower.
Using solution 1 would mean restrictions are placed on the loader location.
Solution 2 was chosen mainly as it was simpler too implement.

This change adds smp debug support for mips platforms. The change
leverages the exiting gdb smp support as mentioned in the OpenOCD
documentation for using gdb in smp environemnt. Added commands
smp_on, smp_off, smp_gdb to control the smp mode. The implementation
also provides a way to send Jc packet and toggle the gdb display core

Like in the previous patch, for speed optimization in write code,
same instructions can be saved if the lower half word or the upper
half word is 0.
If the lower half word is 0, it can be loaded with only a lui instruction.
If the higher half word is 0 it can be done with an ori instruction with register 0.

This function is highly optimized, there is not much to
improve.
Loading the base address for pracc access with the new
defined MIPS32_PRACC_BASE_ADDR saves one instruction.
The memory address is loaded in too steps. First the upper
address is loaded. The lower address is passed as an offset in
the memory load instruction.
The offset is signed, if the lower address is in the range of
0x8000 to 0xffff the offset is a negative value, and the upper
address must be incremented by 1.
Pracc accesses are now 12 instead of 14.

The function mips_ejtag_read_debug() is defined in mips_ejtag.c

CP0 debug register. The comment in this function is obviously wrong.
There is a generic function to read CP0 registers with similar code.
A call to mips32_cp0_read() should work in the same way.
The purpose of reading the debug register is to test if the DSS
bit is set and clear the SSt bit.
It is faster and easier if the SSt bit is cleared without any check.
Remark: DSS bit set only means that a debug single-step exception
ocurred, but it is not possible to step over a sdbbp instruction,
in this case DSS will not be set and the SSt bit not cleared by code.
Resume command at another address will step, so really the behavior
is not the same.

The erase time for the option byte page is not directly specified but is
assumed to be the same as the other pages (or mass erase) which is 20 to
40 ms. The current timeout value is 10 which means 10 ms plus the time to
poll the status flag that many times.
With faster interfaces or drivers (such as when using the ftdi driver
instead of the ft2232 driver) the adapter delay is not enough in some
cases, unless the jtag freq is reduced as a workaround. The result is a
"timed out waiting for flash" error when trying to write the options.
Increase the timeout to a minimum of 100 ms, which is in line with the
other erase timeouts. Also make defines of both the erase and the program

Matthias Blaicher submitted a patch at http://openocd.zylin.com/#/c/891/
to fix the false positive; when no RTOS was detected OpenOCD used the
last RTOS in the list.
While reviewing the code affected by Matthias' patch a rewrite seemed
appropriate, to make the code readable.
Matthias has abandoned his change and this change also fixes the false
positive.

The new code is almost functionally equivalent to the old.
The function now returns 0 instead of -1 if target->rtos has not yet
been allocated. All call sites only test for success, and in practise
that is also the only thing that matters; if the function successfully
iterated to the next RTOS or not.
Other than that the only difference is that the code is now readable.
Many thanks to Matthias Blaicher for the fix to the iteration error!

Because the dseg segment is serviced exclusively by the EJTAG features, there
are no physical address per se. Instead the lower 21 bits of the virtual address select
the appropriate reference in either EJTAG memory or registers. References are not mapped through the
TLB, nor do the accesses appear on the external system memory interface.
Both of this memory segments are Uncached.
On debug exception (break) CPU jumps to the beginning of dmseg. This some kind of memory shared
between CPU and EJTAG dongle.
There CPU stops (correct terminology is : stalls, because it stops it's pipeline), and is waiting for some action of dongle.
If the dongle gives it instruction, CPU executes it, augments it's PC to 0xFFFF FFFF FF20 0001 - but it again points to dmseg area,
so it stops waiting for next instruction.
This will all become clear later, after reading following prerequisite chapters.
@section impflags Important flags
@subsection pnnw PNnW
Indicates read or write of a pending processor access:
- 0 : Read processor access, for a fetch/load access
- 1 : Write processor access, for a store access
This value is defined only when a processor access is pending.
Processor will do the action for us : it can for example read internal state (register values),
and send us back the information via EJTAG memory (dmseg), or it can take some data from dmseg and write it into the registers or RAM.
Every time when it sees address (i.e. when this address is the part of the opcode it is executing, wether it is instruction or data fetch)
that falls into dmseg, processor stalls. That acutally meand that CPU stops it's pipeline and it is waitning for dongle to take some action.
CPU is now either waiting for dongle to take some data from dmseg (if we requested for CPU do give us internal state, for example),
or it will wait for some data from dongle (if it needs following instruction because it did previous, or if the operand address of the currently executed opcode
falls somewhere (anywhere) in dmseg (0xff..ff20000 - 0xff..ff2fffff)).
Bit PNnW describes character of CPU access to EJTAG memory (the memry where dongle puts/takes data) - CPU can either READ for it (PNnW == 0) or
WRITE to it (PNnW == 1).
By reading PNnW bit OpenOCD will know if it has to send (PNnW == 0) or to take (PNnW == 1) data (from dmseg, via dongle).
@subsection pracc PrAcc
Indicates a pending processor access and controls finishing of a pending processor access.
When read:
- 0 : No pending processor access
- 1 : Pending processor access
A write of 0 finishes a processor access if pending;
otherwise operation of the processor is UNDEFINED
if the bit is written to 0 when no processor access is
pending. A write of 1 is ignored.
A successful FASTDATA access will clear this bit.
As noted above, on any access to dmseg, processor will stall. It waits for dongle to do some action - either to take or put some data.
OpenOCD can figure out which action has to be taken by reading PrAcc bit.
Once action from dongle has been done, i.e. after the data is taken/put, OpenOCD can signal to CPU to proceed with executing the instruction.
This can be the next instruction (if previous was finished before pending), or the same instruction - if for example CPU was waiting on dongle
to give it an operand, because it saw in the instruction opcode that operand address is somewhere in dmseg. That prowoked the CPU to stall (it tried operand fetch to dmseg and stopped),
and PNnW bit is 0 (CPU does read from dmseg), and PrAcc is 1 (CPU is pending on dmseg access).
@subsection spracc SPrAcc
Shifting in a zero value requests completion of the Fastdata access.
The PrAcc bit in the EJTAG Control register is overwritten with zero when the access
succeeds. (The access succeeds if PrAcc is one and the operation address is in the legal dmseg segment
Fastdata area.)
When successful, a one is shifted out. Shifting out a zero indicates a Fastdata access failure.
Shifting in a one does not complete the Fastdata access and the PrAcc bit is unchanged. Shifting out a
one indicates that the access would have been successful if allowed to complete and a zero indicates
MIPS32_LW(8,0,9), /* lw $8,0($9), Load $8 with the word @mem[$9] */
MIPS32_SW(8,0,11), /* sw $8,0($11) */
MIPS32_ADDI(10,10,NEG16(1)), /* $10-- */
MIPS32_ADDI(9,9,4), /* $1 += 4 */
MIPS32_ADDI(11,11,4), /* $11 += 4 */
MIPS32_B(NEG16(8)), /* b loop */
MIPS32_NOP,
/* end: */
MIPS32_LW(11,0,15), /* lw $11,($15) */
MIPS32_LW(10,0,15), /* lw $10,($15) */
MIPS32_LW(9,0,15), /* lw $9,($15) */
MIPS32_LW(8,0,15), /* lw $8,($15) */
MIPS32_B(NEG16(27)), /* b start */
MIPS32_MFC0(15,31,0), /* move COP0 DeSave to $15 */
};
@endcode
We have to pass this code to CPU via dongle via dmseg.
After debug exception CPU will find itself stalling at the begining of the dmseg. It waits for the first instruction from dongle.
This is MIPS32_MTC0(15,31,0), so CPU saves C0 and continues to addr 0xFF20 0001, which falls also to dmseg, so it stalls.
Dongle proceeds giving to CPU one by one instruction in this manner.
However, things are not so simple. If you take a look at the program, you will see that some instructions take operands. If it has to take
operand from the address in dmseg, CPU will stall witing for the dongle to do the action of passing the operand and signal this by putting PrAcc to 0.
If this operand is somewhere in RAM, CPU will not stall (it stalls only on dmseg), but it will just take it and proceed to nex instruction. But since PC for next instruction
points to dmseg, it will stall, so that dongle can pass next instruction.
Some instuctions are jumps (if these are jumps in dmseg addr, CPU will jump and then stall. If this is jump to some address in RAM, CPU will jump and just proceed -
will not stall on addresses in RAM).
To have information about CPU is currently (does it stalls wanting on operand or it jumped somewhere waiting for next instruction),
OpenOCD has to call TAP ADDRESS instruction, which will ask CPU to give us his address within EJTAG memory :
if ((retval = mips32_pracc_exec_write(&ctx, address)) != ERROR_OK)
return retval;
}
else
{
/* Check to see if its reading at the debug vector. The first pass through
* the module is always read at the vector, so the first one we allow. When
* the second read from the vector occurs we are done and just exit. */
if ((address == MIPS32_PRACC_TEXT) && (pass++))
{
break;
}
if ((retval = mips32_pracc_exec_read(&ctx, address)) != ERROR_OK)
return retval;
}
if (cycle == 0)
break;
}
@endcode
and using presented R (mips32_pracc_exec_read()) and W (mips32_pracc_exec_write()) functions it reads in the code (RO) and reads and writes operands (RW).
@section fdimpl OpenOCD FASTDATA Implementation
OpenOCD FASTDATA write function, mips32_pracc_fastdata_xfer() is called from bulk_write_memory callback, which writes a count items of 4 bytes
to the memory of a target at the an address given. Because it operates only on whole words, this should be faster than target_write_memory().
In order to implement FASTDATA write, mips32_pracc_fastdata_xfer() uses the following handler :
@code
uint32_t handler_code[] = {
/* caution when editing, table is modified below */
MIPS32_MFC0(15,31,0), /* move COP0 DeSave to $15 */
};
@endcode
In the begining and the end of the handler we have fuction prologue (save the regs that will be clobbered) and epilogue (restore regs),
and in the very end, after all the xfer have been done, we do jump to the MIPS32_PRACC_TEXT address, i.e. Debug Exception Vector location.
We will use this fact (that we came back to MIPS32_PRACC_TEXT) to verify later if all the handler is executed (because when in RAM,
processor do not stall - it executes all instructions untill one of them do not demand access to dmseg (if one of it's opernads is there)).
This handler is put into the RAM and executed from there, and not instruction by instruction, like in previous simple write
(mips_m4k_write_memory()) and read (mips_m4k_read_memory()) functions.
N.B. When it is executing this code in RAM, CPU will not stall on instructions, but execute all until it comes to the :
@code
MIPS32_LW(9,0,8) /* start addr in t1 */
@endcode
and there it will stall - because it will see that one of the operands have to be fetched from dmseg (EJTAG memory, in this case FASTDATA memory segment).
This handler is loaded in the RAM, ath the reserved location "work_area". This work_area is configured in OpenOCD configuration script and should be selected
in that way that it is not clobbered (overwritten) by data we want to write-in using FASTDATA.
What is executed instruction by instruction which is passed by dongle (via EJATG memory) is small jump code, which jumps at the handler in RAM.
CPU stalls on dmseg when receiving these jmp_code instructions, but once it jumps in RAM, CPU do not stall anymore and executes bunch of handler instructions.
Untill it comes to the first instruction which has an operand in FASTDATA area. There it stalls and waits on action from probe.
It happens actually when CPU comes to this loop :
@code
MIPS32_LW(9,0,8), /* start addr in t1 */
MIPS32_LW(10,0,8), /* end addr to t2 */
/* loop: */
/* 8 */ MIPS32_LW(11,0,0), /* lw t3,[t8 | r9] */
/* 9 */ MIPS32_SW(11,0,0), /* sw t3,[r9 | r8] */
MIPS32_BNE(10,9,NEG16(3)), /* bne $t2,t1,loop */
@endcode
and then it stalls because operand in r8 points to FASTDATA area.
OpenOCD first verifies that CPU came to this place by :
@code
/* next fetch to dmseg should be in FASTDATA_AREA, check */
and then passes to CPU start and end address of the loop region for handler in RAM.
In the loop in handler, CPU sees that it has to take and operand from FSTDATA area (to write it to the dst in RAM after), and so it stalls, putting PrAcc to "1".
OpenOCD fills the data via this loop :
@code
for (i = 0; i < count; i++)
{
/* Send the data out using fastdata (clears the access pending bit) */
if ((retval = mips_ejtag_fastdata_scan(ejtag_info, write_t, buf++)) != ERROR_OK)
return retval;
}
@endcode
Each time when OpenOCD fills data to CPU (via dongle, via dmseg), CPU takes it and proceeds in executing the endler. However, since handler is in a assembly loop,
CPU comes to next instruction which also fetches data from FASTDATA area. So it stalls.
Then OpenOCD fills the data again, from it's (OpenOCD's) loop. And this game continues untill all the data has been filled.
After the last data has beend given to CPU it sees that it reached the end address, so it proceeds with next instruction. However, rhis instruction do not point into dmseg, so
CPU executes bunch of handler instructions (all prologue) and in the end jumps to MIPS32_PRACC_TEXT address.
On it's side, OpenOCD checks in CPU has jumped back to MIPS32_PRACC_TEXT, which is the confirmation that it correclty executed all the rest of the handler in RAM,
and that is not stuck somewhere in the RAM, or stalling on some acces in dmseg - that would be an error :
FASTDATA register is 1-bit width register. It takes in SPrAcc bit which should be shifted first,
followed by 32 bit of data.
Scan width of FASTDTA is 33 bits in total : 33 bits are shifted in and 33 bits are shifted out.
First bit that is shifted out is SPrAcc that comes out of Fastdata register and should give us status on FATSDATA write we want to do.
@section fdcheck OpenOCD misses FASTDATA check
Download flow (probe -> target block transfer) :
1) Probe transfer target execution to a loop in target memory doing a fixed number of "loads" to fastdata area of dmseg (and stores to the target download destination.)
2) Probe loops attempting to satisfy the loads "expected" from the target.
On FASTDATA access "successful" move on to next "load".
On FASTDATA access "failure" repeat until "successful" or timeout.
(A "failure" is an attempt to satisfy an access when none are pending.)
Note: A failure may have a recoverable (and even expected) cause like slow target execution of the load loop. Other failures may be due to unexpected more troublesome causes like an exception while in debug mode or a target hang on a bad target memory access.
Shifted out SPrAcc bit inform us that there was CPU access pendingand that it can be complete.
Basically, we should do following procedure :
- Download (dongle -> CPU) :
You shift "download" DATA and FASTDATA[SPrAcc] = 0 (33 bit scan) into the target. If the value of FASTDATA[SPrAcc] shifted out is "1" then an access was pending when you started the scan and it is now complete.
If SPrAcc is 0 then no access was pending to the fastdata area. (Repeat attempt to complete the access you expect for this data word. Timeout if you think the access is "long overdue" as something unexpected has happened.)
- Upload (CPU -> dongle) :
You shift "dummy" DATA and FASTDATA[SPrAcc] = 0 (33 bit scan) into the target. If the value of FASTDATA[SPrAcc] shifted out is "1" then an access was pending when you started the scan and it is now complete. The "upload" is the DATA shifted out of the target.
If SPrAcc is 0 then no access was pending to the fastdata area. (Repeat attempt to complete the access you expect for this data word. Timeout if you think the access is "long overdue" as something unexpected has happened.)
Basically, if checking first (before scan) if CPU is pending on FASTDATA access (PrAcc is "1"), like this
@code
wait(ready);
do_scan();
@endcode
which is inefficient, we should do it like this :
@code
BEGIN :
do_scan();
if (!was_ready)
goto BEGIN;
@endcode
by checking SPrAcc that we shifted out.
If some FASTDATA write fails, OpenOCD will continue with it's loop (on the host side), but CPU will rest pending (on the target side)
waiting for correct FASTDATA write.
Since OpenOCD goes ahead, it will eventually finish it's loop, and proceede to check if CPU took all the data. But since CPU did not took all the data,
it is still turns in handler's loop in RAM, stalling on Fastdata area so this check :
LOG_ERROR("mini program did not return to start");
@endcode
fails, and that gives us enough information of the failure.
In this case, we can lower the JTAG frquency and try again, bacuse most probable reason of this failure is that we tried FASTDATA upload before CPU arrived to rise PrAcc (i.e. before it was pending on access).
However, the reasons for failure might be numerous : reset, exceptions which can occur in debug mode, bus hangs, etc.
If lowering the JTAG freq does not work either, we can fall back to more robust solution with patch posted below.
To summarize, FASTDATA communication goes as following :
-# CPU jumps to Debug Exception Vector Location 0xFF200200 in dmseg and it stalls, pending and waiting for EJTAG to give it first debug instruction and signall it by putting PrAcc to "0"
-# When PrAcc goes to "0" CPU execute one opcode sent by EJTAG via DATA reg. Then it pends on next access, waiting for PrAcc to be put to "0" again
-# Following this game, OpenOCD first loads handler code in RAM, and then sends the jmp_code - instruction by instruction via DATA reg, which redirects CPU to handler previously set up in RAM
-# Once in RAM CPU does not pend on any instruction, but it executes all handler instructions untill first "fetch" to Fastdata area - then it stops and pends.
-# So - when it comes to any instruction (opcode) in this handler in RAM which reads (or writes) to Fastdata area (0xF..F20.0000 to 0xF..F20.000F), CPU stops (i.e. stalls access).
I.e. it stops on this lw opcode and waits to FASTDATA TAP command from the probe.
-# CPU continues only if OpenOCD shifted in SPrAcc "0" (and if the PrAcc was "1"). It shifts-out "1" to tell us that it was OK (processor was stalled, so it can complete the access),
and that it continued execution of the handler in RAM.
-# If PrAcc was not "1" CPU will not continue (go to next instruction), but will shift-out "0" and keep stalling on the same instruction of my handler in RAM.
-# When Fastdata loop is finished, CPU executes all following hadler instructions in RAM (prologue).
-# In the end of my handler in RAM, I jumps back to begining of Debug Exception Vector Location 0xFF200200 in dmseg.
-# When it jumps back to 0xFF200200 in dmseg processor stops and pends, waiting for OpenOCD to send it instruction via DATA reg and signal it by putting PrAcc to "0".
