     Usage: bitbake [options] [recipename/target recipe:do_task ...]

         Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
         It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
         will provide the layer, BBFILES and other configuration information.

     Options:
       --version             show program's version number and exit
       -h, --help            show this help message and exit
       -b BUILDFILE, --buildfile=BUILDFILE
                             Execute tasks from a specific .bb recipe directly.
                             WARNING: Does not handle any dependencies from other
                             recipes.
       -k, --continue        Continue as much as possible after an error. While the
                             target that failed and anything depending on it cannot
                             be built, as much as possible will be built before
                             stopping.
       -f, --force           Force the specified targets/task to run (invalidating
                             any existing stamp file).
       -c CMD, --cmd=CMD     Specify the task to execute. The exact options
                             available depend on the metadata. Some examples might
                             be 'compile' or 'populate_sysroot' or 'listtasks' may
                             give a list of the tasks available.
       -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP
                             Invalidate the stamp for the specified task such as
                             'compile' and then run the default task for the
                             specified target(s).
       -r PREFILE, --read=PREFILE
                             Read the specified file before bitbake.conf.
       -R POSTFILE, --postread=POSTFILE
                             Read the specified file after bitbake.conf.
       -v, --verbose         Enable tracing of shell tasks (with 'set -x'). Also
                             print bb.note(...) messages to stdout (in addition to
                             writing them to ${T}/log.do_<task>).
       -D, --debug           Increase the debug level. You can specify this more
                             than once. -D sets the debug level to 1, where only
                             bb.debug(1, ...) messages are printed to stdout; -DD
                             sets the debug level to 2, where both bb.debug(1, ...)
                             and bb.debug(2, ...) messages are printed; etc.
                             Without -D, no debug messages are printed. Note that
                             -D only affects output to stdout. All debug messages
                             are written to ${T}/log.do_taskname, regardless of the
                             debug level.
       -q, --quiet           Output less log message data to the terminal. You can
                             specify this more than once.
       -n, --dry-run         Don't execute, just go through the motions.
       -S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER
                             Dump out the signature construction information, with
                             no task execution. The SIGNATURE_HANDLER parameter is
                             passed to the handler. Two common values are none and
                             printdiff but the handler may define more/less. none
                             means only dump the signature, printdiff means compare
                             the dumped signature with the cached one.
       -p, --parse-only      Quit after parsing the BB recipes.
       -s, --show-versions   Show current and preferred versions of all recipes.
       -e, --environment     Show the global or per-recipe environment complete
                             with information about where variables were
                             set/changed.
       -g, --graphviz        Save dependency tree information for the specified
                             targets in the dot syntax.
       -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
                             Assume these dependencies don't exist and are already
                             provided (equivalent to ASSUME_PROVIDED). Useful to
                             make dependency graphs more appealing
       -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
                             Show debug logging for the specified logging domains
       -P, --profile         Profile the command and save reports.
       -u UI, --ui=UI        The user interface to use (knotty, ncurses or taskexp
                             - default knotty).
       --token=XMLRPCTOKEN   Specify the connection token to be used when
                             connecting to a remote server.
       --revisions-changed   Set the exit code depending on whether upstream
                             floating revisions have changed or not.
       --server-only         Run bitbake without a UI, only starting a server
                             (cooker) process.
       -B BIND, --bind=BIND  The name/address for the bitbake xmlrpc server to bind
                             to.
       -T SERVER_TIMEOUT, --idle-timeout=SERVER_TIMEOUT
                             Set timeout to unload bitbake server due to
                             inactivity, set to -1 means no unload, default:
                             Environment variable BB_SERVER_TIMEOUT.
       --no-setscene         Do not run any setscene tasks. sstate will be ignored
                             and everything needed, built.
       --setscene-only       Only run setscene tasks, don't run any real tasks.
       --remote-server=REMOTE_SERVER
                             Connect to the specified server.
       -m, --kill-server     Terminate any running bitbake server.
       --observe-only        Connect to a server as an observing-only client.
       --status-only         Check the status of the remote bitbake server.
       -w WRITEEVENTLOG, --write-log=WRITEEVENTLOG
                             Writes the event log of the build to a bitbake event
                             json file. Use '' (empty string) to assign the name
                             automatically.
       --runall=RUNALL       Run the specified task for any recipe in the taskgraph
                             of the specified target (even if it wouldn't otherwise
                             have run).
       --runonly=RUNONLY     Run only the specified task within the taskgraph of
                             the specified targets (and any task dependencies those
                             tasks may have).

Операция	Описание
`d.getVar("X", expand)`	Возвращает значение переменной X, преобразуя значение при expand=True. Если переменной X нет, возвращает None.
`d.setVar("X", "value")`	Устанавливает для переменной X значение value.
`d.appendVar("X", "value")`	Добавляет value в конце переменной X. Ведет себя как d.setVar(“X”, “value”) при отсутствии переменной X.
`d.prependVar("X", "value")`	Добавляет value в начале переменной X. Ведет себя как d.setVar(“X”, “value”) при отсутствии переменной X.
`d.delVar("X")`	Удаляет переменную X из хранилища при ее наличии.
`d.renameVar("X", "Y")`	Переименовывает переменную X в Y, если она существует.
`d.getVarFlag("X", flag, expand)`	Возвращает значение переменной X, преобразуя значение при expand=True. Если переменной X или флага нет, возвращает None.
`d.setVarFlag("X", flag, "value")`	Устанавливает для флага переменной X значение value.
`d.appendVarFlag("X", flag, "value")`	Добавляет value в конец флагов переменной X. Ведет себя как d.setVarFlag(“X”, flag, “value”) при отсутствии флага.
`d.prependVarFlag("X", flag, "value")`	Добавляет value в начало флагов переменной X. Ведет себя как d.setVarFlag(“X”, flag, “value”) при отсутствии флага.
`d.delVarFlag("X", flag)`	Удаляет из хранилища флаг переменной X.
`d.setVarFlags("X", flagsdict)`	Устанавливает флаг, заданный в параметре flagsdict, не сбрасывая имеющийся флаг (как addVarFlags).
`d.getVarFlags("X")`	Возвращает flagsdict флагов переменной X или None, если X нет.
`d.delVarFlags("X")`	Удаляет все флаги переменной X при ее наличии.
`d.expand(expression)`	Преобразует переменную, указанную строкой expression. Ссылки не отсутствующие переменные не меняются. Например, d.expand(“foo ${X}”) преобразует строку foo ${X}, если переменной X не существует.
