Opps, my fail. "go" command occurs ^^!.

About "exec" command. Does it require MMU to load Linux kernel?
http://www.arm.com/community/software-enablement/linux.php?tab=uClinux
this link said that uClinux & u-boot can run with *NON MMU* ARM
processors. Do you have any ways to run bootloader and Linux kernel
(uClinux) on *NON MMU* ARM??? Thanks so much.
