Software Reference
4.2.1 Flash ROM
The Flash ROM is an 8 MB Intel StrataFlash
®
(part# 28F640) that sits on the Peripheral Bus and is
accessed using PCE0.
Under normal operation, the very first instruction access by the Intel XScale® core begins at location
0x0 on the 80332 Internal Bus. By default, address 0x0 is pointing to PCE0 where flash is located.
Currently, the Intel Flash Recovery Utility (FRU) cannot be used with the IQ80332. An 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.
