It basically permits you to map arbitrary blocks of Flash into the address space (not actually as RAM). If you just want to read from it then you can simply access those addresses as if they were ROM. If you want to write to it then you need to do a bit more work, since most flash requires explicit erase cycles as they can't flip bits both ways. > What is the MTD_UCLINUX? That is a mapping driver which supports the "root fs appended to kernel image" design. If you get to your root fs some other way, then you don't need this, but if you do, that's how Linux finds it. _______________________________________________ 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
