But suddenly the execution stops while > enabling the MMU in src/sys/arm/arm/locore.S: I'm not 100% shure, since what Warner suggested to get our board running just worked, but I assume the kernel needs to be copied and therefor it is mandantory to use the kernel.tramp. I personally use kernel.gz.tramp, but I expect a non compressed image should work as well. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
