I am using a Buspirate v3b in transparent UART with 115200 baudrate, etc as shown here: (link)
buspirate cable:
what I am doing:
CLK does appear to be resetting the arduino in time, and I have tried pressing the reset button myself to no avail. I have soldered a 15k resistor pulling up my RST pin, but to no effect.
No errors appear in the arduino IDE, cannot upload Blink sketch with Arduino pro mini 5V 16mhz option (matches board). Problem same across two different pro mini boards.
