You would need to be able to alter the boot parms, which you'll only be able to change if you have access to uBoot ( as far as I can see ).

Seems like with LE32B550 uboot access is broken because it has not the network components it needs:

Code: Select all

ONBOOT :: 96100128 6420642
BOARD  :: EU


U-Boot 1.1.6 (Jan 28 2009 - 15:44:37)

It's frozen always on this line (Err: serial) where normally the next line is (based on wiki):
