If you've never connected the IOIO to a PC, the blinking might be a signal that means that clock calibration is required. Connect it to a PC once to make it go away for good.
I don't know what the specs of the dynamo are, but my gut feeling is that it is very likely that it would probably not supply a clean 5V @ 0.5A. The processor may be browning out although that in theory shouldn't be causing the yellow LED to blink. If all you need is to charge the phone, why do you need the IOIO in the middle at all???
