<b>NOTE</b>:

<code>examples/nsh/rcS.template</code> generates the standard, default <code>nsh_romfsimg.h</code> file.
|

If <code>CONFIG_EXAMPLES_NSH_ARCHROMFS<code> is defined in the NuttX configuration file, then a custom, board-specific <code>nsh_romfsimg.h</code> file residing in <code>configs/<board>/include</code> will be used.

- The configuration settings then installed configuration.
