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: clunc 1.1

Repository: clunc.git

The documentation is in the README file.

Boot your kernel

  • Connect to U-Boot using network console with 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'.
