[U-Boot] U-Boot Loop

[Tran, Dang]

Hi,

I'm running a PowerPC board that uses U-Boot and I get into this loop (see terminal output below).
It doesn't matter how I get into this loop. What I really care about is how to break out of it without manually resetting the board.
Is there a way to break out of this loop and reset the system via the terminal? Ctrl-X and Ctrl-C doesn't seem to do anything.
