Ethernet over serial line on the eb63

The eb63 has no ethernet chip but it has two serial lines. This page explains how to use your PC as a proxy.

  1. First get the NTU simulator networking working. The same packet driver and second ethernet card is used on the PC side (the same ethernet card can be used only by one program at a time so the simualtor can't be used simultaneously).
  2. Flash a file system image (eb63fs.flp) into the flash as explained in the eb63 instructions. E.g. if the board is USER then type something like eb_flash.exe 1000000 fs/ebfs.flp 180000
  3. Flash a base image (eb63big.bin) that boots from RomFs.
  4. Plug Cable-1 into your PC on COM2 and start serplexd on the NT side 

    HOST> %MMLITE_SDK%\build\i386\release\bin\serplexd COM2
    Serplexd does some filtering so as to not overload the serial line.
  5. Run 
    > sock.exe sr0 dhcp
    The above command will start protocol stack, sernet automatically.

    6. Now the board is on the ethernet and there are two file systems: fs and srfs. The local file system is fs and the remote is srfs.
