You don't need to initialize the UPM in order to reprogram flash devices via BDM; you just have to enable the appropriate chip select via the relevant BRx and ORx register. Two register writes is all you need (assuming your BDM already disables the pesky watchdog for you). What BDM are you using? Embedded Planet tech support should be able to help you with this sort of thing.
