Other Uses of Built-In Application. The primary purpose of builtin applications is to support command line execution of applications from NSH. - However, there are two other uses of builtin applications that should be mentioned. + However, there is one other use of builtin applications that should be mentioned.

    - Built-In Application Start-Up main() function. - A builtin application can even be used as the main, start-up entry point into your embedded software. - When the user defines this option in the NuttX configuration file: -

    -
      -CONFIG_BUILTIN_APP_START=<application name>
-
    -

    - that application will be invoked immediately after system starts instead of the default CONFIG_USER_ENTRYPOINT() entry point. - Note that <application name> must be provided just as it would have been on the NSH command line. - For example, hello would result in hello_main() being started at power-up. -

    -

    - This option might be useful in some develop environments where you use NSH only during the debug phase, but want to eliminate NSH in the final product. - Setting CONFIG_BUILTIN_APP_START in this way will bypass NSH and execute your application just as if it were entered from the NSH command line. -

This gives some superficial Unix compatibility, but does not really add any new functionality. -
