Today, there is a build target is added for each runner: flash, debug,
debugserver, attach.
And those runners will have a dependency to Zephyr logical target that
is built before invoking `west <runner>`.
This design has some flaws, mainly that additional dependencies directly
on the target will not be built when running `west <runner>` directly.
That generator expressions cannot be used for the DEPENDS argument.
Instead, the build target `<runner>` will not have any dependencies, and
will raise a build error if a dependency is added to the target.
Due to how `add_dependencies()` work, this must be done as a build time
check, and not configure time check.
`west <runner>` will invoke a build before executing the runner, and
this way ensure the build target is up-to-date, which again removes the
need for a dedicated `west_<runner>_target`.
It also minimizes the risk of developer errors, as developers no longer
need to consider the need for adding additional dependencies.
If a custom target is part of the default `all` build, then it's ensured
to be up-to-date.

When CONFIG_MCUBOOT_SIGNATURE_KEY_FILE is set and the build system
successfully creates signed outputs, use them as the default artifacts
to flash.
This flashes the non-confirmed variant regardless of
CONFIG_MCUBOOT_GENERATE_CONFIRMED_IMAGE, allowing POST code in the
application to confirm the image or not. Since this is used primarily
from development, I'd hesitate to assume the confirmed image is good.

This commit message is a bit of a novel mostly:
- because the issues involved are longstanding
- as evidence this is not a capricious refactoring
The runners.core.RunnerConfig Python class holds common configuration
values used by multiple runners, such as the location of the build
outputs and board directory.
The runners code, first written in 2017-ish, replaced various shell
scripts that got this information from the environment. Avoiding
environment variables was a requirement, however. It's ghastly to set
environment variables for a single command invocation on Windows, and
the whole thing was part of a larger push to make Zephyr development
on Windows better.
I had a hammer (the argparse module). Finding a replacement naturally
looked like a nail, so the information that ends up in RunnerConfig
got shunted from the build system to Python in the form of 'west
flash' / 'west debug' command line options like '--board-dir',
'--elf-file', etc.
I initially stored the options and their values in the CMake cache.
This was chosen in hopes the build system maintainer would like
the strategy (which worked).
I knew the command line arguments approach was a bit hacky (this
wasn't a nail), but I also honestly didn't have a better idea at the
time.
It did indeed cause issues:
- users don't know that just because they specify --bin-file on the
command line doesn't mean that their runner respects the option, and
have gotten confused trying to flash alternate files, usually for
chain-loading by MCUboot (for example, see #15961)
- common options weren't possible to pass via board.cmake files
(#22563, fixed partly via introduction of runners.yaml and the west
flash/debug commands no longer relying on the cache)
- it is confusing that "west flash --help" prints information about
openocd related options even when the user's board has no openocd
support. The same could be said about gdb in potential future use
cases where debugging occurs via some other tool.
Over time, they've caused enough users enough problems that
improvements are a priority.
To work towards this, put these values into runners.yaml using a new
'config: ...' key/value instead of command line options.
For example, instead of this in the generated runners.yaml file:
args:
common:
- --hex-file=.../zephyr.hex
we now have:
config:
hex_file: zephyr.hex
and similarly for other values.
In Python, we still support the command line options, but they are not
generated by the build system for any in-tree boards. Further work is
needed to deprecate the confusing ones (like --hex-file) and move the
runner-specific host tool related options (like --openocd) to the
runners that need them.
Individual board.cmake files should now influence these values by
overriding the relevant target properties of the
runners_yaml_props_target.
For example, instead of:
board_runner_args(foo "--hex-file=bar.hex")
Do this:
set_target_properties(runners_yaml_props_target PROPERTIES
hex_file bar.hex)
This change additionally allows us to stitch cmake/mcuboot.cmake and
the runners together easily by having mcuboot.cmake override the
properties that set the hex or bin file to flash. (The command line
arguments are still supported as-is.)
Combined with 98e0c95d91ae16f14e4997fb64ccdf0956595712 ("build:
auto-generate signed mcuboot binaries"), this will allow users to
build and flash images to be chain loaded by mcuboot in a way that
avoids calling 'west sign' and passing 'west flash' its output files
entirely.
While we are here, rename runner_yml_write to runners_yaml_append().
This function doesn't actually write anything, and we're here
refactoring this file anyway, so we might as well improve the
situation while we're at it.

This commit creates a list of a phony targets for each runner, that is:
`west_flash_depends`, `west_debug_depends`, and so on.
Those targets has identical dependencies as CMake runner target.
flash, debug, debugserver, attach targets.
As example `ninja flash` correctly ensures dependencies are taken into
consideration before calling `west flash`.
Unfortunately, calling `west flash` directly would not re-run the flash
dependencies, cause `west flash` would only build the default CMake
target.
Now, `west flash` calls the phony `west_flash_depends` target, ensuring
all deps are up-to-date before flashing (unless --skip-rebuild is given)

There are two problems with the way runners.yaml is being created:
1. The dictionary which contains the arguments for each runner is
using the runner's name converted to a C identifier instead of the
runner's name itself. That causes west flash to fail when the two
are different, e.g. for 'misc-flasher' (runner name), which is
different than 'misc_flasher' (runner name as C identifier)
2. We need to make sure that the dictionary key maps to an empty list
if there are no arguments, which normally doesn't happen since the
runner usually at least takes the path of the file to flash or debug.
It does happen in the case of misc-flasher, though, since the whole
point of that runner is that it's an escape hatch for people with
out of tree scripts that nevertheless want 'west flash' integration
for things like sanitycheck device testing.
3. A copy/paste error is setting the debug runner to the flash runner.
Fix them all.

This makes it possible for Python to intermix them with

Of the 1.7s or so that CMake spends in Configure-time there is 0.1s
spent to determine whether west can flash or not. This is significant
compared to the usefulness of flash-check.
AFAICT when installing west there is no longer a two-step procedure
where first a bootstrapper that can't flash is installed, and then a
proper west is installed, so the risk of having installed the
bootstrapper is no longer something we should spend 100ms testing for.
This patch removes the check, thereby speeding up CMake by 100ms.

Update to the latest west. This includes a new 'attach' command. There

Replace the launchers; they now detect whether zephyr is part of a

if that is the case.
This also requires an update to:
- the flash/debug CMakeLists.txt, as the new west package is no longer
executable as a module and must have its main script run by the

Continue better integration of the runner subpackage into west by
moving the common runner configuration options into the command
core. This allows commands like "west flash -h" to display help for
common overrides like --kernel-hex.
Adjustments needed to make this happen are:
- Change the build system to separate common configuration values from
runner-specific options and arguments
- Prepare the runner core by defining a new RunnerConfig class that
represents the common configuration, and accepting that from a new
create() method, which replaces create_from_args().
- Convert all concrete runner classes to use the new style of
argument parsing and initialization.
- Group the command options appropriately for help output readability
There's still a bit of tool-specific stuff in the common
configuration (gdb and openocd configuration in particular); a more
generic way to deal with that will be necessary to better support
things like non-GDB debuggers, but that's out of scope of this patch.
All the runner-specific options are still in the runner packge, which
currently prevents them from being included in "west flash -h" etc.
Fixing that is also out of scope of this patch.
This has the ancillary benefit of getting rid of the legacy 'debug'
argument to ZephyrBinaryRunner, which is no longer appropriate since
verbose debug logging is handled by log.py in west.

The various runners (flash/debug scripts) use environment variables to
take arguments. This is legacy behavior which is not desirable.
Use command line arguments instead.
Note: this leaves more general environment variables with publicly
documented behavior in place for now, for compatibility, e.g.:
ZEPHYR_FLASH_OVER_DFU, OPENSDA_FW, ESP_IDF_PATH, PYOCD_DAPARG
For example, when using dfu-util to flash arduino_101, instead of
setting DFUUTIL_PID, DFUUTIL_ALT, and DFUUTIL_IMG environment
variables, have the script invocation look like this:
python3 .../zephyr_flash_debug.py dfu-util flash \
[common arguments omitted] \
--pid=8087:0aba --alt=x86_app \
--img=.../build/zephyr/zephyr.bin
Make similar changes for other runners (openocd, etc.) and
targets (debug, debugserver).
To implement this in the scripts:
- have the individual scripts/support/runner/some-runner.py files
register their own command line arguments
- teach them to construct instances from arguments, not the
environment
- have zephyr_flash_debug.py request runners to register command
line argument parsers, and handle arguments
In the build system:
- add a new board_runner_args() extension function that board.cmake
files can use to add to the zephyr_flash_debug.py command line
- adjust cmake/flash/CMakeLists.txt to invoke with arguments
- add new helper include files for each runner (like
boards/common/dfu-util.board.cmake, etc.), which add default
options as needed and then add on overrides from
board_runner_args() calls
- update board.cmake files to use the new includes and extension
This implied some tweaking when using openocd to make the CMake string
escaping and unescaping work properly.

The Python-based runners have replaced the old shell scripts. Refactor
the build system accordingly:
- FLASH_SCRIPT is now BOARD_FLASH_RUNNER
- DEBUG_SCRIPT is now BOARD_DEBUG_RUNNER
The values, rather than being the names of files, are now the names of
runners in scripts/support/runner. They are still short, descriptive
names like "openocd", "jlink", "em-starterkit", etc.
Adjust the zephyr_flash_debug.py call and runner internals
accordingly. Have each runner class report a name and the commands it
can handle. This lets us move some boilerplate from each do_run()
method into the common run() routine, and enables further improvements
in future patches.
The handles_command() method is temporary, and will be replaced by a
more general mechanism for describing runner capabilities in a
subsequent patch. The initial use case for extending this is to add
device tree awareness to the runners.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:

$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
