1. The input consists of multiple static libraries and an ELF file. The tool searches for external APIs used by the static libraries, then locates these API function signatures in the ELF file, and outputs the results as a JSON file. 2. Using the first feature, with the static libraries unchanged, the tool can take a new ELF file and an old ELF file as input, output two JSON files, and compare the function signatures of functions with the same name in the two JSON files. The comparison includes return values, parameters, and if they are structures, it also compares the structure size, member offsets, member types, etc. 3.When the input is a single ELF file, the tool can check if structures with the same name have different members.

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.
