Yes, Wolfgang, it is 32-bit register. I used => md ff2800A0 1 => md ff2800A0 2 => md ff2800A0 4 => md.b ff2800A0 1 => md.b ff2800A0 2 => md.b ff2800A0 4 and I've got the same result, the system is hang _______________________________________________ eldk mailing list [email protected] http://lists.denx.de/mailman/listinfo/eldk
