---help---
The file system is assumed to reside on some external media
such as an SD card or a USB FLASH drive. In this case, that
external file system must be created manually by copying the
files in apps/examples/elf/tests/romfs to the volume.
The external volume can optionally be mounted by the test if
the CONFIG_EXAMPLES_FSMOUNT option is also selected.
