Oh, excellent. The 2.4.26 mmap code does not do that, which is why I needed the driver. It's not XIP in ROM, but is sharing code segments in RAM in the same way (and same compiler options), which is critical for my application. It reduces no-MMU fragmentation considerably. You say private R/O - not shared R/O? -- Jamie _______________________________________________ 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
