Command Syntax:

+ Synopsis. + The 'm ount' command mounts a file system in the NuttX psuedo + filesystem. 'mount' performs a three way associating, binding: +

+
    +
  1. File system. + The '-t <fstype>' option identifies the type of + file system that has been formatted on the <block-device>. + As of this writing, vfat is the only supported value for <fstype> +
    2. +
  2. Block Device. + The <block-device> argument is the full or relative + path to a block driver inode in the pseudo filesystem. + By convention, this is a name under the /dev sub-directory. + This <block-device> must have been previously formatted with the same file system + type as specified by <fstype> +
    3. +
  3. Mount Point. + The mount point, <dir-path>, is the location in the + pseudo filesystem where the mounted volume will appear. + This mount point can only reside in the NuttX pseudo filesystem. + By convention, this mount point is a subdirectory under /mnt. + The mount command will create whatever psuedo directories that may be needed to complete the + full path but the full path must not already exist. +
