Under normal operation, the very first instruction access by the Intel XScale® core begins at location 0x0 on the 80333 Internal Bus. By default, address 0x0 is pointing to PCE0 where Flash is located.

Currently, the Intel Flash Recovery Utility (FRU) can be used with the IQ80333. Another alternative to FRU would be to reprogram the Flash through JTAG or using Redboot commands, when Redboot is currently loaded onto the board. For more information on using Redboot to program the Flash, please see Redboot Manual.
