Switch every qemu-armv8a defconfig whose init entry point was nsh_main (20 configs) to nxinit (init_main). nsh now runs as a "console sh" service started by init.rc instead of being the top-level init task. Each switched defconfig only gains the nxinit-essential keys (minimal delta): - CONFIG_INIT_ENTRYPOINT="init_main" - CONFIG_SYSTEM_NXINIT=y plus its Kconfig deps not already set: CONFIG_EXPERIMENTAL, CONFIG_LIBC_EXECFUNCS, CONFIG_SCHED_CHILD_STATUS (depends on CONFIG_SCHED_HAVE_PARENT) - CONFIG_ETC_ROMFS=y / CONFIG_FS_ROMFS=y to ship init.rc via ROMFS No stack-size overrides: INIT_STACKSIZE/SYSTEM_NSH_STACKSIZE keep their Kconfig defaults (DEFAULT_TASK_STACKSIZE, already 8192 on this board). Add boards/arm64/qemu/qemu-armv8a/src/etc/init.d/init.rc, shipped via ROMFS in the Make build (RCSRCS) and CMake (nuttx_add_romfs()), gated on CONFIG_ETC_ROMFS && CONFIG_SYSTEM_NXINIT. Omitting this ROMFS plumbing causes a link-time "undefined reference to romfs_img". Testing: qemu-armv8a:nsh (and nsh_smp with -smp 4) boot into nxinit with nsh spawned as its service (init task = init_main, sh = its child), confirmed via qemu-system-aarch64 in an earlier run of this series. The removed explicit 8192 stack sizes equal this board's DEFAULT_TASK_STACKSIZE, so runtime behavior is unchanged. Note: current apache/master fails to build locally this round (empty -Wstack-usage=, missing libfdt.h) independent of this change.

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.
