When the uC is reset, single step the program once. The uC (always) gets the correct data, but the PC gets back 0xFF (just after reset). Now run the program w/o single step. Everything works fine.
Most likely, in single step, you start the UART in one step, but all that is transmitted is the start bit, this will make a 0xff be the received byte. Erik |
