I've lost some of the context on the board you are working with, but
from ttyAMA2, I'm assuming it is an arm board. Have you verified that your
bootloader can pass the kernel bootline properly to the kernel ? It is
(unfortunately) fairly common that it isn't properly passed. If you
modify your configuration to have a built in command line with your
configuration, you may be able to get better setup to debug the
problem.

Cheers,
