CFE> flash -mem

     flash [options] filename [flashdevice]

     Copies data from a source file name or device to a flash memory device.
     The source device can be a disk file (FAT filesystem), a remote file
     (TFTP) or a flash device.  The destination device may be a flash or eeprom.
     If the destination device is your boot flash (usually flash0), the flash
     command will restart the firmware after the flash update is complete

     -offset=*    Begin programming at this offset in the flash device
     -size=*      Size of source device when programming from flash to flash
     -noheader    Override header verification, flash binary without checking
     -forceflash  Dangerous Command, Don't use if you don't know what you do
     -erase       Erase the partition, can set the  offset and length
     -writechksum Write image checksum to the end of partition
