Erm. 405 and 440 have entirely different MMUs. 405 has real-mode, and 440 is BookE and therefore has the MMU always on. That is mostly an impact to the kernel itself and not to userspace. But it can be annoying if you aren't used to dealing with BookE style CPUs. josh _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
