Add NuttX support for the Realtek AmebaSmart (RTL8730E) running on the
CA32 (Cortex-A32) application core, with the KM4/KM0 cores kept as
vendor firmware (KM4 acts as the WiFi network processor over WHC IPC).
Stage 1 bring-up, hardware verified:
- CA32 boot / exception vectors / MMU + page allocator / heap
- LOGUART console (RX via KM0-owned IPC + shared memory)
- IRQ controller, timer, serial
- On-chip SPI NOR flash MTD -> littlefs mounted at /data
- WHC-host WiFi netdev (STA): scan / connect / DHCP, verified end to
end (association -> 4-way -> DHCP -> ping, bidirectional TCP)
IC-agnostic Ameba glue is shared from arch/arm/src/common/ameba via a
relative VPATH entry (matching the rtl8721dx pattern), which also avoids
the empty mkdeps --dep-path that a leading-":" VPATH entry produced and
which intermittently broke parallel .ddc dependency generation.
The FIP packaging / flash image assembly is driven by
common/ameba/tools/ameba_smart_flash.sh from the board scripts.
Vendor blobs and build artefacts under the board prebuilt/ directory are
kept out of the tree via prebuilt/.gitignore.

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.
