I have the MEMMAP = 2 as the first line in my main.

Done that, but the handler newer gets called.

After having looked at the elf file with objdump it seems as if the
VIC interrupt handler points to the an address 3fffffef (or similar
isn't at work just now) - but that's in the flash! So maybe it is my
startup code that's wrong?

I have ldr pc, [pc, #-0x0FF0] (again - it's taken from my memory) as
my VIC handler and it works in flash. Is it the same in RAM?
