Hi James,
I'm using U-Boot 2010.06 (Jun 18 2013 - 14:03:16)
This is a version of U-Boot that is even older than the version I used
for my demonstration that ctrl-c works. (I used 2010.12)
You should make efforts towards using a more recent version.
What information can you provide as to the settings of your serial
terminal emulator? Is it known to send your ctrl-c to the target device?

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.
It might be helpful to know which version of U-Boot you are using.

Please make sure your serial communication terminal emulator correctly transmits the
ctrl-C when you type it. To see if this works, get to a U-Boot prompt and type
ctrl-C, you should see <INTERRUPT>
