no i have not connected tyhe DTR or CTS. but i tried resetting just before down load and still it does not work. Can u tell me the status of TXO pin in idle condition of the ProMini. Is it High or lo?
On mine it is LO.
mellis:
What board is the FT232 on? Did you connect DTR or RTS from the FT232 through a 0.1 uF capacitor to reset on the Pro Mini? Otherwise, you'll need to manually reset the Pro Mini right before (or right after) hitting the upload button in the Arduino software.
