Hi,

I'm trying to use initramfs on an ML403 system but don't understand why I = can't see any console output after the line:

[    1.034361] Freeing unused kernel memory: 1172k init  =

 

my filesystem is built from the following:

dir /dev 755 0 0
nod /dev/console 644 0 0 c 5 1
dir /proc 755 0 0
dir /sys 755 0 0
file /init usr/busybox 755 0 0

 

Busybox was built statically, with init functionality so I think I can just = rename it to init and it should run the init process.   It seems to find /dev/console because if I delete that node I get an error message that = it can't find /dev/console.   Also I think it is finding the busybox = init because I don't get a kernel panic like I do when I don't include = it.

Any help would be great.

Thanks,
Joe
