Replace the CMake skeleton with full SDK build machinery, mirroring the make-side ameba_board.mk. RTL8730E differs from the KM4-based ICs in three ways that prevent a direct include(ameba_board.cmake): - No SDK autoconf / image2 ldscript generation: the board uses its own dramboot.ld and a static prebuilt platform_autoconf.h - No NP firmware build: KM0/KM4 are prebuilt blobs in prebuilt/ - No -mcmse: CA32 is ARMv7-A, not Cortex-M33; uses -DCONFIG_ARM_CORE_CA32 The ameba_build_lib() helper (adapted from ameba_board.cmake) compiles SDK sources with an isolated flag set into libameba_fwlib.a and libameba_wifi.a, avoiding NuttX header conflicts. Key additions: - libameba_fwlib.a: arch.c + log.c + sscanf_minimal.c always; IPC for WiFi/FlashFS; ameba_flash_ram.c for FlashFS - lib_rom.a linked for GPIO or FlashFS (GPIO_Init, Pinmux_Config, etc.) - libameba_wifi.a + prebuilt WHC host libs for WiFi - VFS1 geometry extracted from platform_autoconf.h via target_compile_definitions (set_property(SOURCE) has scope issues in NuttX's include()-based CMake structure) - `flash` target calls ameba_smart_flash.sh Verified: gpio (1186 targets) and nsh (1530 targets) configs both build cleanly; /data mounts at correct 2 MB partition size.

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.
Contributing
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.
