Swift 6 on NuttX RTOS using CMake

Description

Run blink rv32-blink_leds (QEMU) example on NuttX RTOS.

Note

CMake is adapted to build NuttX and NuttX-apps (Makefiles) with Swift 6.

Requirements

How to build

# list all supported boards
cmake -B build -DLIST_ALL_BOARDS=ON | less
# build configuration
cmake -B build -GNinja -DBOARD_CONFIG=rv-virt:leds_swift -DENABLE_NUTTX_TRACE=[ON|OFF]
# build
cmake --build build
# clean
cmake --build build -t distclean
# export NuttX as library
cmake --build build -t nuttx-libs
