when I first powered up the mcb900 out of the box the hello program ran with a white power led and successful output to hyperterminal. I changed the program, couldn't download through uvision 3 because of "can't execute FM.exe". I successfully downloaded with flash magic. Now when I try to run the power led is red I get no output to hyperterminal. Changing the programming on the lights is succesful. Does the red light in run mode mean there is a problem with the serial connection?
