================ Host File System ================ The Host file system provides a mechanism to mount directories from the host OS during simulation mode. The host directory to be "mounted" is specified during the mount command using the ``-o`` command line switch, such as:: mount -t hostfs -o fs=/home/user/nuttx_root /host For non-NSH operation, the option ``fs=home/user/nuttx_root`` would be passed to the ``mount()`` routine using the optional ``void *data`` parameter.
