Zynq> mtd
mtd - MTD Sub-system

Usage:
mtd list                        - show list of MTD devices
mtd info                        - show current MTD device info
mtd probe devnum                - probe the 'devnum' MTD device
mtd erase offset len            - erase 'len' bytes from 'offset'
mtd write addr to len           - write 'len' bytes to 'to' from 'addr'
mtd read addr from len          - read 'len' bytes from 'from' to 'addr'
