you don't have any "bootargs" setup!! this might be it
Q2. I marked several places above by "<<--??". Any one see those before? If you do, please let me know how to fix them.
If I understand correctly your problem, it is quite simple actually. You need a variable "bootargs" to be passed to the kernel... you could do something like that:
setenv console=ttyS0,9600 ip=$(ipaddr) root=$(root)
type that and with your u-boot settings, it should work.
good luck Raphaël
