Currently only FLAT mode development can enjoy cmake build system. This patch tries to add initial kernel mode support. It can build NuttX kernel and libproxies.a, the latter will be further checked though. This can already help to build an AMP remote node image as it can share userland apps living in the AMP master node. Major changes: - in top folder: - CMakeLists.txt adjust for KERNEL mode, separate from PROTECTED mode. - in `syscall`: - CMakeLists.txt add mksyscall target for stubs/proxies generation - in `syscall/stubs`: - CMakeLists.txt use dependency to mksyscall - in `syscall/proxies`: - CMakeLists.txt use dependency to mksyscall - in `arch`: - CMakeLists.txt separate KERNEL from PROTECTED mode. - in `arch/risc-v/src`: - CMakeLists.txt separate from PROTECTED mode, add sub folders. - in `arch/risc-v/common`: - CMakeLists.txt add sources and sub-folders for KERNEL mode. - in `arch/risc-v/k230`: - CMakeLists.txt add sources for KERNEL mode. - in `boards/risc-v/k230/canmv230/src`: - CMakeLists.txt adjust k230 specific scripts for kernel mode. New additions: - in `arch/risc-v/src/nuttsbi/` add CMakeLists.txt - in `arch/risc-v/src/common/supervisor/` add CMakeLists.txt Signed-off-by: Yanfeng Liu <yfliu2008@qq.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.
