Some keyboard shortcuts supported by kconfig-mconf, the tool that runs when you do 'make menuconfig':. The NuttX configuration options have gotten complex and it can be very difficult to find options in the menu trees if you are not sure where to look.
The "basic configuration order" describe above can help to narrow things down. It will show you not only where to find the configuration item, but also all of the dependencies related to the configuration item. If you type Z , then kconfig-mconf will change what is displayed. Normally, only enabled features that have all of their dependencies met are displayed.
That is, of course, not very useful if you would like to discover new options or if you are looking for an option and do not realize that the dependencies have not yet been selected and, hence, it is not displayed. But if you enter Z , then every option will be shown, whether or not its dependencies have been met.
You can then see everything that could be selected with the right dependency selections. These additional options will be shown the - for the selection and for the value since it cannot be selected and has no value. Saved configurations may run on Linux, Cygwin or bit , or other platforms.
The platform characteristics can be changed use make menuconfig. Sometimes this can be confusing due to the differences between the platforms. Enter sethost. This can greatly simplify life if you use many different configurations. For example, if you are running on Linux and you configure like this:.
The you can use the following command to both 1 make sure that the configuration is up to date, AND 2 the configuration is set up correctly for Linux:. Other options are available from the help option built into the script. You can see all options with:. Recently, the options to the configure. If you try to compare two configurations using 'diff', you will probably not be happy with the result.
There are superfluous things added to the configuration files that make comparisons with the human eye difficult. The output from this difference tool will show only the meaningful differences between two configuration files. This tool is built as follows:.
Why would you want to compare two configuration files? Here are a few of the reasons why I do this. When I create a new configuration I usually base it on an older configuration and I want to know, "What are the options that I need to change to add the new feature to the older configurations?
But the most common reason that I use the 'cmpconfig' program is to check the results of "refreshing" a configuration with 'make oldconfig' see the paragraph "Refreshing Configurations" above. The 'make oldconfig' command will make changes to my configuration and using 'cmpconfig', I can see precisely what those changes were and if any should be of concern to me.
The 'cmpconfig' tool can also be useful when converting older, legacy manual configurations to the current configurations based on the kconfig-frontends tools. See the following paragraph. The minimum defconfig file is simply the generated. The default is.. For example, the name of versioned NuttX releases are always in the form apps-xx. The Makefile also supports an option to generate very small defconfig files.
But most of the settings in the. That make target will generate a defconfig file in the top-level directory. The size reduction is really quite remarkable:. In order to be usable, the. All patches and PRs that attempt to add or modify a defconfig file MUST use the compressed defconfig format as created by 'make savdefconfig.
NOTE 2 : When 'make savedefconfig' runs it will try several things some of which are expected to fail.
In these cases you will see an error message from make followed by " ignored. The underlying assumption here is, of course, that the default settings do not change. If the default settings change, and they often do, then the original. As described above defconfig , all NuttX defconfig files are compressed using make savedeconfig. These compressed defconfig files are generally not fully usable as they are and may not build the target binaries that you want because the compression process removed all of the default settings from the defconfig file.
To restore the default settings, you should run the following after configuring:. Using this command after configuring is generally a good practice anyway: Even if the defconfig files are not "compressed" in this fashion, the defconfig file may be old and the only way to assure that the installed.
See the paragraph above entitled "Refreshing Configurations" for additional information. The current NuttX build system supports only the new compressed, defconfig configuration files generated using the kconfig-frontends tools as described in the preceding section. Support for the older, legacy, manual configurations was eliminated in NuttX 7.
All configurations must now be done using the kconfig-frontends tool. The older manual configurations and the new kconfig-frontends configurations are not compatible. Old legacy configurations can not be used with the kconfig-frontends tool and, hence, cannot be used with releases of NuttX 7. If you run make menuconfig with a legacy configuration the resulting configuration will probably not be functional.
Q: How can I tell if a configuration is a new kconfig-frontends configuration or an older, manual configuration? Q: How can I convert a older, manual configuration into a new, kconfig-frontends toolchain. As described above, whenever you use a configuration, you really should always refresh the configuration with the following command before you make NuttX:. This will make sure that the configuration is up-to-date in the event that it has lapsed behind the current NuttX development see the paragraph "Refreshing Configurations" above.
But this only works with new configuration files created with the kconfig-frontends tools. Further, this step is NOT optional with the new, compressed defconfig files. It is a necessary step that will also uncompress the defconfig file, regenerating the. Never do make oldconfig OR make menuconfig on a configuration that has not been converted to use the kconfig-frontends tools! But kconfig-frontends is a Linux tool. At one time this was a problem for Windows users, but now there are two specially modified versions of the kconfig-frontends tools that can be used.
The configuration steps of the most recent versions of NuttX require the kconfig-tweak tool that is not not available in the the above. It is also possible to use the version of kconfig-frontends built under Cygwin outside of the Cygwin sandbox in a native Windows environment:. You can run the configuration tool using Cygwin. However, the Cygwin Makefile. For example, change.. You can, with some effort, run the Cygwin kconfig-mconf tool directly in the Windows console window.
In this case, you do not have to modify the. You need to temporarily set the Cygwin directories in the PATH variable then run kconfig-mconf manually like:. There is an issue with accessing DOS environment variables from the Cygwin kconfig-mconf running in the Windows console. The following change to the top-level Kconfig file seems to work around these problems:. In order to build NuttX for your board, you will have to obtain a cross- compiler to generate code for your target CPU.
That README file contains suggestions and information about appropriate tools and development environments for use with your board. In any case, the PATH environment variable will need to be updated to include the location where the build can find the toolchain binaries.
These tools can be downloaded from the NuttX Bitbucket. Disadvantages: This tool chain is not was well supported as some other toolchains. GNU tools are not my priority and so the buildroot tools often get behind.
If the make system ever picks the wrong prefix for your toolchain, you can always specify the prefix on the command to override the default like:. The NuttX build relies on some shell scripts. The scripts were all developed using bash and many contain bash shell dependencies.
Most of the scripts begin with! Some still have! In this case, bash is probably available and the! If any scripts with! The other, reverse case has also been reported on FreeBSD setups that have the Bourne shell, but not bash.
In this base,! There may still be issues, however, with certain the bash -centric scripts that will require modifications. NuttX builds in-place in the source tree. You do not need to create any special build directories. Assuming that your Make.
At least one configuration eagle requires additional command line arguments on the make command. But there are some things that can "get you" when you use the Cygwin development environment with Windows native tools.
The native Windows tools do not understand Cygwin's symbolic links, so the NuttX make system does something weird: It copies the configuration directories instead of linking to them it could, perhaps, use the NTFS mklink command, but it doesn't. A consequence of this is that you can easily get confused when you edit a file in one of the linked i. That is because build is still using the version of the file in the copied directory, not your modified file! Older versions of NuttX did not support dependencies in this configuration.
So a simple work around this annoying behavior in this case was the following when you re-build:. This 'make' command will remove of the copied directories, re-copy them, then make NuttX. However, more recent versions of NuttX do support dependencies for the Cygwin build. A much less gracefully but still effective command in this case is the following for the ARM configuration:. This "kludge" simple removes the copied directories.
These directories will be re-created when you do a normal 'make' and your edits will then be effective. Removes derived object files, archives, executables, and temporary files, but retains the configuration and context files and directories. Does 'clean' then also removes all configuration and context files. This essentially restores the directory structure to its original, unconfigured stated. Application housekeeping targets. For the most part, the application directory is treated like any other build directory in the Makefile script.
However, as a convenience, the following targets are included to support housekeeping functions in the user application directory from the NuttX build directory. Perform the distclean operation only in the user application directory. The export target will package the NuttX libraries and header files into an exportable package. This is a helper target that will rebuild NuttX and flash it to the target system in one step.
The following targets are used internally by the make logic but can be invoked from the command under certain conditions if necessary. Create build dependencies. Download Now. Your email address will not be published.
