Should that be updated too? Or are you just limiting the region to > the registers currently described rather than the allocated address space? Ah, actually, I see what's going on. We really have this layout (taking some liberties): 0x1e785000 - 0x1e785500: PGPIO 3.3V 0x1e785500 - 0x1e785600: SGPM1 0x1e785600 - 0x1e785700: SGPM2 0x1e785700 - 0x1e785740: SPGS1 0x1e785740 - 0x1e785780: SPGS2 0x1e785800 - 0x1e786000: PGPIO 1.8V Ryan: Can you change the address space layout table to reflect this? That way it still functions as a quick - but accurate - reference. Andrew
