Добрый день! С некоторых пор перестал грузиться маршрутизатор 1841. входит в rommonitor нормально, но когда делаешь tftpdnld пишет:
get_mac_address(): Search T_IDPROM_MACADDR (0xc3) fai
led

Illegal MAC address.

usage: tftpdnld [-hr]
    Use this command for disaster recovery only to recover an image via TFTP.
    Monitor variables are used to set up parameters for the transfer.
    (Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.)
    "ctrl-c" or "break" stops the transfer before flash erase begins.

    The following variables are REQUIRED to be set for tftpdnld:
                        IP_ADDRESS: The IP address for this unit
                IP_SUBNET_MASK: The subnet mask for this unit
              DEFAULT_GATEWAY: The default gateway for this unit
                      TFTP_SERVER: The IP address of the server to fetch from
                          TFTP_FILE: The filename to fetch

    The following variables are OPTIONAL:
                    TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default), 2=verbose
            TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=18)
                    TFTP_TIMEOUT: Overall timeout of operation in seconds (default=7200)
                  TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1)
                              FE_PORT: 0= (default), 1
                  FE_SPEED_MODE: 0=10/hdx, 1=10/fdx, 2=100/hdx, 3=100/fdx,
                                                4=Auto (default)

    Command line options:
      -h: this help screen
      -r: do not write flash, load to DRAM only and launch image

Если делаешь xmodem то:
rommon 25 > xmodem -c 1841
