Not sure but you may have the TX and RX lines swapped, swap them and give it a shot. Another thing is that you might have to power cycle or reset the chip right before uploading the program to put the boot loader into the programming mode.


OK I'VE GOT IT, I didn't read it at first but with this converter you have to connect its DTR pin to the reset button of the AtMega with a coupling capacitor, this way it resets right before being programmed, another thing that I had wrong is the programer selected in Arduino GUI, it has to be usb.
