I have the Universal SL Dev Kit with 2 socket boards. The SL6087 socket board works fine. I can connect UART1 through a serial port to my laptop and issue some basic AT commands. When I plug in the SL5011 and set the switches properly to SW600-Open SW601-L as the doc describes, I get nothing but junk on the serial port. Is there something magic I need to do to make the SL5011 socket board work?
