chao an a506f9fb70 Revert "cmake: restore old behavior for savedefconfig"
@raiden00pl I'm surprised why this commit was reverted. It maintains the same functionality as tools/refresh.sh. this change is a good improvement because overwriting the original defconfig to prevent developers from missing out on enabled or disabled features during the development process. If you find any changes in the defconfig after saving it, you should manually restore it, git diff will tell you what has happened. and also this feature prevents more junior developers from forgetting to save their own defconfig

This reverts commit 751bc1528a.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
