You two choices:
Buy a debugger, light some led's or wiggle pin with a different
number of pules to help you figure out where  you're hanging.
The console is enabled very early in the booting process and if
you don't see anything (assuming the code is correct for UART),
you are hanging very soon after the reset vector...
