Hi

It actually looks like you have TX to TX and RX to RX you should just check the wiring. When everything is working I would recommend you solder permanent wires as using jumpers can sometimes cause issues.

As for your problem when you program the firmware you plug both sides of the adapter into the computer and when prompted you unplug and re plug the cable going to the AVR board it should then update you have 10 seconds to do this. If you still don't get it to work just connect the AVR board and when prompted quickly short out RST and GND on the AVR.
