no, because with a MMU, the memory would be virtualized and we could handle it dynamically > It looks like a way for certain special executables to load themselves > into fixed regions of the on-chip SRAM - and promptly crash if another > executable does the same.

What am I missing here? the addresses are keys, not fixed and/or "real" addresses -mike _______________________________________________ uClinux-dev mailing list [email protected] http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by [email protected] To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
