Does that mean if I use a USB-to-TTL cable (Such as the 'USB to Serial TTL Cable' from CoolComponents, say) I can get rid of the usb chip and program the ATMega directly?
Again, I know that for the Arduino 2009/Uno you can burn the bootloader via the USB if you use the Arduino IDE
If we're talking about the same FTDI cable then I think you can use pin 2 (RTS) to do the same job. I'm pretty sure this gets toggled as well.
