well, I have two LEDs on my board for 'very hardware debug' (I know it's VERY
cheap, but it's very useful too ;-), so I try to turn one LED on before the
jump ('rfi' call) and another at the beginning of 'start_here' procedure. As
you can guess - first LED turned on but second didn't.

Any idea? Could be something wrong with my cross-compiler? Initialization of
MMU? Stack?
I'm pretty much down on this :-(
