I'll just assume your uImage is correct - although I don't understand why 
you don't just do make uImage. Apart from that, verify that your console= 
command line parameter is correct, your machine ID matches, and that you 
don't have a jtag debugger like bdi2000 connected when you're trying to 
boot.
