Well, this is NOT a usable root file system. First, static linking
with glibc is not excactly doing what you might think it does; second,
the kernel tries to start "init", not "test"; third, user space
applications expect a certain environment like stnadar input and
output channels connected to devices, and all the other things a real
init process will do for them.


Why don't you use the ramdisk image that comes with the ELDK?

Best regards,

Wolfgang Denk
