"go" command occurs ^^!. About "exec" command. Does it require MMU to load Linux kernel? http://www.arm.com/community/software-enablement/linux.php?tab=3DuClinux 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.
