I still don't understand why you feel the need to do that. Once uClinux is booted there is no way to get back into dBUG (unless you've got some weird code), so it doesn't matter if you overwrite the RAM that dBUG was using. I think you should just change PAGE_OFFSET_RAW to 0x40000000 and leave it at that. (caveat: I don't use either 2.4 or 5208) _______________________________________________ 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
