That is, every character is output as a blank -- you can : see them printing, and see the 10 second autoboot messages, but : they're all space characters. I have seen this when I've had the baud rate wrong. On my development box that has a serial console, I seem to recall that I needed to build special bootblocks to run at 115200. Try connecting a serial line analyser to the line if you have it. Or a oscope will do in a pinch. Or try the default baud rate of 9600.
