Add generic support for link-time registration of struct instances, modeled after the Zephyr STRUCT_SECTION_* mechanism: - include/nuttx/iterable_sections.h: STRUCT_SECTION_ITERABLE/DECLARE/ FOREACH/GET/COUNT macros placing instances in name-sorted linker sections delimited by _<type>_list_start/_end symbols (attributes through the nuttx/compiler.h macros; FOREACH takes a caller-declared iterator, like list_for_every_entry). - include/nuttx/linker/iterable_sections.ld: ITERABLE_SECTION() macro emitting the KEEP + SORT_BY_NAME collection statements (linker scripts in ARCHSCRIPT are CPP-preprocessed). - include/nuttx/linker/common-rom.ld / common-ram.ld: central aggregators meant to be included by board linker scripts (inside .text and .data respectively); subsystems register their sections here guarded by their Kconfig options, so the fragments expand to nothing on configurations that do not use them. - CONFIG_ITERABLE_SECTIONS_LINKER_INSERT + include/nuttx/linker/ common-insert.ld (added before the board script by tools/Config.mk and by the top-level CMakeLists.txt): optional zero-touch mode that supplements the board script through GNU ld INSERT AFTER, collecting the subsystems' ITERABLE_SECTION blocks in one output section; the common-rom.ld/common-ram.ld fragments expand to nothing in that mode. See the option help for the constraints. - Documentation/components/iterable_sections.rst. First user: the Zephyr zbus message bus port (apps/system/zbus in nuttx-apps); its board integration comes in a companion PR. Signed-off-by: Jorge Guzman <jorge.gzm@gmail.com> |

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.
