This worked great for me, and I got my amdcfi component to more or less wor= k,=20 but have one more hurdle to overcome: The processor is an arm7t with a 32 bit bus. The flash is a 16 bit device.= =20 (The component can also be an 8 bit device, but I don't need this=20 particularly.) In our actual hardware, we have a mapper that will read and= =20 register two 16 bit addresses on the flash and shift/concatenate them to fo= rm=20 a single 32 bit word when the processor executes a 32 bit read. (This allow= s=20 us to execute non-thumb instructions out of flash for example.) I haven't y= et=20 found a way to make the SID mapper do this. Is this currently possible? Am = I=20 looking in the wrong place? Am I going to have to do some re-writing?
