examples
^^^^^^^^
examples/ostest
This is the NuttX 'qualification' suite. It attempts to exercise
a broad set of OS functionality. Its coverage is not very extensive
as of this writing, but it is used to qualify each NuttX release.
examples/nsh
This directory containst the NuttShell (NSH). This is a primitive
shell-like application. With some additional development, NSH will
someday be a great NuttX application debugger.
examples/null
This is the do nothing application. It is only used for bringing
up new NuttX architectures
