====== CLUNC (Client for LaCie U-Boot NetConsole) ======

CLUNC uses the network (ethernet cable) to connect to U-Boot.

**No need of custom serial cable** to play with a LaCie NAS !

Latest release: [[ftp://lacie-nas.org/tools/clunc-1.1.tar.gz|clunc 1.1]]

Repository: [[http://git.lacie-nas.org/?p=clunc.git;a=summary|clunc.git]]

The documentation is in the [[http://git.lacie-nas.org/?p=clunc.git;a=blob_plain;f=README;hb=HEAD|README file]].


==== Boot your kernel ====

  * Connect to U-Boot using network console with [[CLUNC|clunc]]:

As a preliminary step, you must export your kernel uImage via **tftp** . U-Boot will use this way to load the kernel image into RAM.

  $ ./clunc -i ${NAS_IP}

  Marvell>> setenv ipaddr ${ipaddr}; setenv serverip ${serverip}; tftpboot 0x800000 uImage
  setenv ipaddr ${ipaddr}; setenv serverip ${serverip}; tftpboot 0x800000 uImage
  Using egiga0 device
  TFTP from server ${serverip}; our IP address is ${ipaddr}
  Filename 'uImage'.
