In trying to use the serial Flash ISP for the first time, I got a connection and downloaded new code. The code had some bugs, and now I can't connect any longer. When you attempt to put the MCB2140 in manual ISP mode by using SW1 and SW2, is there an indication? How do I tell? I will be using the JTAG later. Just trying to get the serial version working reliably.
They are set per the document. But, still will not connect to serial port as it did before.
