``refresh.sh``

==============

|
.. note::
|
|
|
|
This script with ``--silent`` is obsolete.
|
|
|
|
The silent option adds default values, however, as of 2017-07-09,
|
|
defconfig files are retained in a compressed format, i.e. with default values
|
|
removed. So the ``--silent`` option will accomplish nothing. Without
|
|
``--silent``, you will have the opportunity to override the default values
|
|
from the command line and, in that case, the script may still have some
|
|
minimal value.
|
|
|
|
This is a bash script that automates refreshing board default configuration
|
|
(defconfig) files. It does not do anything special that you cannot do manually,
|
|
but is useful for updating dozens of configuration files. It is also used in the
|
|
NuttX CI process.
|
|
|
|
Configuration files have to be updated because, over time, the configuration
|
|
settings change; new configurations are added and new dependencies are added.
|
|
So an old configuration file may not be usable anymore until it is refreshed.
|

|
|
tools/refresh.sh is a tool for refreshing board configurations
|
|
|
|
USAGE: tools/refresh.sh [options] (<board>:<config>|<path/to/config/folder>)+
|
|
|
|
Where [options] include:
|
|
--debug
|
|
Enable script debug
|
|
--silent
|
|
Update board configuration without interaction. Implies --defaults.
|
|
Assumes no prompt for save. Use --silent --prompt to prompt before saving.
|
|
--prompt
|
|
Prompt before updating and overwriting the defconfig file. Default is to
|
|
prompt unless --silent
|
|
--defaults
|
|
Do not prompt for new default selections; accept all recommended default values
|
|
--nocopy
|
|
Do not copy defconfig from nuttx/boards/<board>/configs to nuttx/.config
|
|
--help
|
|
Show this help message and exit
|
|
<board>
|
|
The board directory under nuttx/boards/arch/chip/
|
|
<config>
|
|
The board configuration directory under nuttx/boards/arch/chip/<board>/configs
|
|
<archname>
|
|
The architecture directory under nuttx/boards/
|
|
<chipname>
|
|
The chip family directory under nuttx/boards/<arch>/
|
|
<path/to/config/folder>
|
|
Relative or absolute path the configuration subdirectory
|
|
|
|
Note1: all configurations are refreshed if <board>:<config> is replaced with "all" keyword
|
|
Note2: all configurations of arch XYZ are refreshed if "arch:<namearch>" is passed
|
|
Note3: all configurations of chip XYZ are refreshed if "chip:<chipname>" is passed
|
|
Note4: all configurations of board XYZ are refreshed if "board:<boardname>" is passed
|
|
|
|
The steps to refresh the configurations and/or files given to ``refresh.sh`` are:
|
|
|
|
1. Copy the defconfig file to the top-level NuttX directory as ``.config`` and its
|
|
corresponding ``Make.defs`` file (being careful to save any previous identically
|
|
named files that you might want to keep).
|
|
|
|
2. Execute ``make oldconfig`` to update the configuration. ``make oldconfig``
|
|
will prompt you for each change in the configuration that requires that you
|
|
make some decision. With the ``--defaults`` option, the script will use ``make
|
|
oldefconfig`` instead and you won't have to answer any question; the refresh
|
|
will simply accept the default value for any new configuration setting.
|
|
|
|
3. Execute ``make savedefconfig`` to create the new defconfig file. Any setting set
|
|
to its default value is stripped down from this file.
|
|
|
|
This will also strip down the ``CONFIG_APPS_DIR`` and ``CONFIG_BASE_DEFCONFIG``
|
|
settings. They should not be in checked-in defconfig files because they must be
|
|
determined each time the configuration is installed.
|
|
|
|
4. Check for any difference between the generated defconfig and the original
|
|
configuration file using the ``diff`` utility.
|
|
|
|
If there are differences, it save the new configuration (with or without prompt
|
|
depending on the ``--silent`` and ``--prompt`` options).
|
|
|
|
5. Restore the ``.config`` and ``Make.defs`` files from step 1.

Usage examples
|
|
--------------
|
|
|
|
Update all boards without verbose output:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults all
|
|
|
|
Update all boards and configs from `arm` architecture:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults arch:arm
|
|
|
|
Update all boards from ``stm32f7`` chip family:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults chip:stm32f7
|
|
|
|
Update all configs from ``stm32f103-minimum`` board:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults board:stm32f103-minimum
|
|
|
|
Update only the `nsh` config from ``stm32f103-minimum`` board:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults stm32f103-minimum:nsh
|
|
|
|
Update the `hello` config from the ``arduino-mega2560`` board and the `ostest` config
|
|
from the ``sim`` pseudo-board:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults arduino-mega2560:hello sim:ostest
|
|
|
|
Update the `nsh` config from ``stm32f103-minimum`` board, using the path to the
|
|
configuration subdirectory:
|
|
|
|
.. code:: console
|
|
|
|
$ ./tools/refresh.sh --defaults boards/arm/stm32f1/stm32f103-minimum/configs/nsh
