VMU access flash storage

RAW access to the VMU flash storage can be done using the mtd-utils mtd_debug. mtdinfo /dev/mtd0 shows information about the VMU.

mtd_debug info /dev/mtd0
mtd_debug read /dev/mtd0 0 255 myvmu.bin

# and if you want to write:
# mtd_debug write /dev/mtd0 0 10 testfile.bin

You can also create a small FAT Filesystem on the VMU:

mkfs.vmufat /dev/mtdblock0
mount -t vmufat /dev/mtdblock0 /mnt/
