It's a nice instruction set, and a CPU with an MMU is a lot nicer to work with. So assuming it isn't too expensive (it probably isn't), it is probably a good choice. I know we would rather have used a powerpc with MMU than a coldfire without on the boards we use the coldfire, but costs involved with the powerpc option (more voltage rails to feed, much more expensive ram, etc) made the powerpc option impractical. uclinux on the coldfire works fine for the task though. -- Len Sorensen _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
