a. To prevent file system corruption, make sure that the AT25 is un-
mounted *before* exporting the mass storage device to the host:
The AT25 can be re-mounted after the mass storage class is disconnected:
nsh> umount /mnt/at25
nsh> mscon
nsh> msdis
nsh> mount -t vfat /dev/mtdblock0 /mnt/at25

b. If you change the value CONFIG_EXAMPLES_USBMSC_DEVPATH1, then you
can export other file systems:
"/dev/mmcsd1" will export the HSMCI1 microSD
"/dev/mmcsd0" will export the HSMCI0 full-size SD slot
"/dev/ram0" could even be used to export a RAM disk. But you would
first have to use mkrd to create the RAM disk and mkfatfs to put
a FAT file system on it.

in this configuration.
