NAME

       elbpcom - Communicate with Mesa ethernet cards

SYNOPSIS

       Common options:

              elbpcom [--ip=IP] [--port=PORT] [--timeout=TIMEOUT] [--space=MEMSPACE] [--size=TRANSFER_SIZE]

       Reading data:
              elbpcom [common options] [--info] --address=ADDRESS --read=LENGTH

       Writing data:
              elbpcom [common options] --address=ADDRESS --write=HEXDATA

       Read and decode memory space info area:
              elbpcom [--space=MEMSPACE] --read-info

       Sending arbitrary packets:
              elbpcom [common options] HEXDATA

DESCRIPTION

       Read or write data from a Mesa ethernet card that uses the LBP16 protocol, such as the 7I80.  This can be
       useful for performing certain low-level tasks.

       For more information about the meaning of each address space, see the card documentation.  Incorrect use
       of this utility can have negative effects such as changing the board's IP address or even corrupting the
       FPGA bitfile in the eeprom.  For some tasks, such as updating FPGA bitfiles and setting IP addresses,
       mesaflash(1) is a more appropriate tool.

       If not specified, the default values are
              --ip=192.168.1.121 --port=27181 --timeout=.2 --space=0 --size=0

       If the --size argument TRANSFER_SIZE is 0, elbpcom will look up the preferred transfer size of the space
       in the space's info area.

       This example demonstrates reading the HOSTMOT2 identifying string from the IDROM in space 0:
              $ elbpcom --address 0x104 --read 8
              > 82420401
              < 484f53544d4f5432
                    HOSTMOT2
       First the request is shown in hex.  Then the response (if any) is shown in hex.  Finally, the response is
       shown in ASCII, with "." replacing any non-ASCII characters.  This is similar to the following
       invocations of mesaflash:
              $ ./mesaflash  --device 7i80 --rpo 0x104
              54534F48
              $ ./mesaflash  --device 7i80 --rpo 0x108
              32544F4D
       but notice its different treatment of byte order.
