In this configuration, the FAT file system will not be automatically
monounted. When NuttX boots to the NSH prompt, you will find the
SST5 block driver at /dev/mtdblock0. This can be formatted with a
FAT file system and mounted with these commands:
nsh> mkfatfs /dev/mtdblock0
nsh> mount -t vfat /dev/mtdblock0 /mnt/sst25
