Where will the ITCM be located at reset?

Applies to: ARM926EJ-S

Answer

The ITCM will be mapped at 0x00000000 at reset and enabled if the INITRAM pin is asserted AND the VINITHI pin is deasserted; in this case, code will be fetched from 0x00000000 over the ITCM interface. If both INITRAM and VINITHI are asserted, then the first instruction is fetched from 0xFFFF0000 over the AHB interface.
