Interrupts are not running, you don't have a kernel. So no.
The nearest you have is that Redboot has a poll loop. When redboot has
nothing to do, it calls do_idle() which calls a list of idle
functions. You could hook this and blink your LED. But by the time
this is being called, booting is over. Redboot is running.
