Is there RAM or ROM here? It seems to be never mentioned at all..
ARM needs the reset and interrupt vectors in that region, so I decided to read it with a flash utility to see what happens on startup. The region *is* different from any other, and contains the string "May 10 2000....DCT3 ALGORIT".
The entry point is at 0x20. I really can't figure out what the routine does though, it subsequently writes to the same range (1000-2000 et al) .. so it could be RAM as well, mysterious.
Does anyone know more?
