  • If you use the FTDI breakout board instead you can get it to work by NOT setting the processor to the 5V Pro Mini 16MHZ mega328 option. Use the 3.3 V Pro Mini 8 MHz mega328 option, as the FTDI breakout board runs on 3.3V. I had your problem exactly until I realized the processor needed it to be seen as 3.3 V. Further experimentation revealed trouble with loading large files. I’m using Windows 7, so I also checked for serial port settings. In my case it was COM12. I set the baud rate to 57600, enabled hardware handshaking. Finally I changed the programmer setting to ‘use Arduino as ISP’ and then it didn’t have problems with loading files bigger than the blink sketch. So far so good, I think that will make it work properly, good luck.

No public wish lists :(
