You could use the old "printf" technique to see how far it gets (or
"diag_printf" would be better in eCos). But my first guess would be some
problem with the clock interrupt. If you were having problems with the
memory mapping, perhaps the IRQ vector is not pointing into the memory map
with the correct addresses.
