apache/nuttx: README-based editorial guide

apache/nuttx describes itself in the README as "Apache NuttX is a mature, real-time embedded operating system (RTOS)". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "README", the README says: 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. That establishes the project's stated boundary, not a production test.

The README's "License" section gives a useful starting point for deciding whether the project fits: README 没有列出这一项具体能力。. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: README 没有列出这一项具体能力。. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "Supported Boards". The source evidence includes: NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: README 没有给出可直接复制的安装命令。 When the README contains no runnable command, this article does not invent one. Open its "License" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
